Composed of various parts of the steel plate in front of the lipp silo has been done many times that today I come to explain to you the next use and various parts of the production process.

  1: Basic Foundation

   Steel reinforced concrete foundation lipp silo foundation for a ring structure, with the C30 is made of reinforced concrete casting, steel lipp silo foundation wall perpendicular to the ground, within the inner wall of the bottom-up cut steel lipp silo foundation. lipp silo foundation than steel aboveground and underground parts of 2: 3. Due to the special nature of cement steel lipp silo inventory objects, in the production of steel should be used for expansion of the lipp silo cement concrete quality requirements, the incorporation of an appropriate amount of alunite UEA expansive concrete in C30, so the foundation can withstand 10 standard atmospheric pressure is completely permeable, no leakage; while the inner and outer surfaces of the steel lipp silo based polymer materials and asphalt, and so do the two strengthen waterproof, so the lipp silo impermeability grade steel to meet or exceed P12, which is not under the pressure of 1.2MPa infiltration drain. Through the implementation of these measures can solve the lipp silo foundation seepage from the plate, gassing technical barrier.

2: lipp silo body

    lipp silo body steel lipp silo is composed of steel lipp silo lipp silo roof, wall and plate steel lipp silo database lipp silo lipp silo at the end of three parts. (1): steel top plate lipp silo lipp silo lipp silo lipp silo is a ball missing the top body, the lower and welded steel plate attached to the lipp silo. Hemispherical body steel skeleton lipp silo, each ball nullisomic 1-3 million tonnes steel by 36 libraries are the main beam, 36 deputy beam; each ball nullisomic 5-20 tons of steel lipp silo are the main beam by 54, 54, vice beam composed of main beam angle steel welded beams of flat steel welded deputy; lipp silo top 1-20 million tons of steel ring beam as well as the lipp silo, the ball is from the beam top plate lipp silo lipp silo-like distribution center outward in concentric circles, the distribution is separated from the ball one meter beam path between each ring beam, the beam is made of flat steel ball welded. Steel base plate for hemispherical body skin: skin thickness of 1-3 million tons of steel for 4-6mm; skin plate thickness 5-20 million tons of 6-8mm. Body of missing the ball at the center of the platform is a channel to the lipp silo roof girders together: 1-3 ten thousand tons used channel model is 12-16; 5-20 tonnes channel model 18-22. Skin plate thickness Platform: lipp silo 1-3 million tons of steel 12-14mm; lipp silo 5-10 million tons of steel 16-18mm. No feed inlet at the center of the platform, the exhaust port (by ESP) and lipp silo roof rails. In the external skin polyurethane foam composite steel steel (thickness 30-35mm) thermal insulation corrosion proof treatment to ensure that the cement between -50 ℃ -160 ℃, the physical indicators steel lipp silo unchanged. (2): steel wall plate lipp silo lipp silo lipp silo lipp silo walls are welded together by a thickness ranging from steel, steel plate welded junction lipp silo database cylindrical wall, from the bottom plate thickness used in the lipp silo of 1-3 million tons of steel and on are 12,10,8,6mm; 5-20 tons steel lipp silo is 26,24,22,20,18,16,14,12,10,8mm bottom-up, respectively, in the lipp silo wall the inside has reinforced the link system, lipp silo wall and the entire steel reinforcement system link lipp silo into a whole. In the lipp silo wall steel with a layer of polyurethane foam outer protective layer made ​​of composite board, he can play a waterproof, moisture, cold, high temperature, corrosion and other functions, steel lipp silo in minus 50 degrees to 160 degrees in the environment the various storage physical indicators unchanged. In the outer wall of the lipp silo has a lipp silo database through the steel roof of the ladder, the ladder is welded angle iron, steel, flat steel and iron made​​. (3): steel body steel lipp silo lipp silo lipp silo lipp silo at the end, there are two design patterns, 1-3 tons steel conical bottom structure lipp silo database structure; 5-20 of tons of steel lipp silo database conical top of polycyclic . The design concept of the expansion of the lipp silo in the bottom area, reducing pressure on the lipp silo at the end of storage, while the bottom of the conical steel libraries also facilitate the settlement plus a solid foundation to achieve density and improve the bearing capacity of the foundation, steel storage capacity reaches saturation of the required foundation bearing capacity. In the bottom of the outer steel lipp silo database set up two reinforcing waterproof layer, a layer of asphalt waterproof layer, another layer of polymer waterproof layer. In the bottom plate lipp silo database and then set the internal surface of a layer of corrosion-resistant waterproof layer in order to achieve the above P12 waterproof rating, ensure cement or steel lipp silo storage in the lipp silo of the physical and chemical indicators of change. Structure of the lipp silo at the end of C35 reinforced concrete structure, the thickness of the steel bottom 1-3 tons lipp silo database for 20-30cm, 5-20 tons of reservoir bottom thickness 25-40cm, lipp silo lipp silo at the end of its steel used in concrete all add alum expanders, in order to achieve the above impermeable P12 grade, waterproof rating of one.

3: Discharge System

    Steel lipp silo system consists of gas discharge pipes, exhaust pipes, bank gasification pipes, pneumatic sweep material pipes, screw the feeder and discharge channel six parts.

    (1): gas steel pipe DN250 lipp silo using standard type of seamless steel gas main conduit arranged in the center of the gasification zone within the discharge passage, the air supply side of the main channel base plate arranged in the gasification zone lipp silo lipp silo wall outside. (2): the exhaust duct is a standard lipp silo plate type DN250 seamless manner and a gas supply which is arranged the same as the main channel, and alternatively a combination of gasification of the exhaust pipe distributed pipe.

    (3): steel pipe storage body gasification using standard lipp silo type DN250 seamless steel pipe with the outer layer of soft metal tube, the outer tube is a soft metal tube with a layer of rock cotton, pipe arrangement for vaporized by the end of the central lipp silo was extended outward circular, the distance of 50cm. Ring gasification tube parallel distance from the lipp silo at the end of 30cm, it has four regions of different pressure components.

    (4): steel lipp silo discharge system, the most important is the aerodynamic sweep steel lipp silo lipp silo materials pipeline device, which is made ​​of seamless steel pipe DN250 type of distribution of steel strip by the center outward radiation distribution was arranged . Gas transport pipeline installed in parallel with the distance from the bottom of the pipe lipp silo database for 20cm, it is composed of four different pressure region piping components. Outward pressure is gradually increased from the central area, the most critical is the flat nozzle pressure nozzle. In the gasification feed tube and spiral out feeder role, cement or other basic storage lipp silo emptying rate reached about 80%. The main effect of the material all the time by the high-pressure nozzle to complete the pneumatic tube. Cement steel lipp silo lipp silo at the end of the role of high-pressure nozzles, gradually spiral out feeder sent outside the lipp silo, the last high-pressure nozzle like a broom every corner of the cement would like to spiral out of all feeder entrance.

    (5): a steel screw feeder base is a self-closed discharge machine, which provides storage of the cement or other material out from the lipp silo into the bottom of the pipe, both the discharge pressure of the air pipe has a much , can not enter the inner feeder, because in the feeder terminal has set back pressure valve. It is simply the output of cement or other storage, outside of what the gas can not enter steel bank. This is to protect steel lipp silo does not enter the wet gas gas initiatives. Screw feeder set out in the center of the reservoir bottom plate at a minimum, and the lipp silo at the end vertical, and a bracket and reducers to discharge machine fixed. 1-3 ten thousand tons each have a screw out of the feeder, 5-20 ten thousand tons each with four spiral out feeder. (6): the steel sheet base with a discharge passage and the angle plate is welded, which is a solution of a cross-sectional shape of an isosceles triangle three corridors, the thickness of the steel sheet are used basically 1-20 tons 8, 12,16mm thickness of steel, angle steel is used in 80 × 80 × 8mm, 100 × 100 × 10mm models of the angle. Discharge channel steel exports in the lowermost part of the lipp silo lipp silo wall, entrance in the upper spiral discharge machine, the material channel has reinforcing means it solid stability. Each machine has a discharge outlet channel, channel steel we designed the lipp silo on the ground in order to facilitate water reservoir bottom one, the second is to facilitate the settlement of the uniform steel lipp silo, then there are steel lipp silo to check out the feeding system .

4: Control Systems
