Shiyan PPH reactor manufacturing
The key manufacturing method used in the production of PPH storage tank is one-time forming coiling manufacturing method, so it is simple in structure. The application of PPH storage tank is relatively convenient due to its simple construction. When the rubber bearing is a plastic rubber bearing, the compressive strength, stiffness, service life and total number of manufacturing shall be considered. When the rubber bearing is a metal rubber bearing, the other standards shall be the same as 1. In addition, the surface of metal rubber bearing shall be corrosion resistant. When the rubber bearing is a concrete rubber bearing, the concrete rubber bearing of the first horizontal tank shall consider the compression strength provisions, and the total number of rubber bearings shall be 2. When there are several rubber bearings, their design elevation shall be the same, and there is no need for uneven ground settlement, and the bottom shall be basically flat.

The thickness requirements for the bottom plate and top plate of PPH storage tank, the previous welding process is to use a portable welding gun to melt the welding rod, and then weld the tank body and bottom plate together. Since the welding rod is an external accessory, it cannot guarantee the consistency of the material with the bottom plate and tank body, which has a certain impact on the quality of equipment. Using a portable welding gun to weld, it cannot achieve the same welding strength, and the weld surface is uneven, There are many hidden dangers for equipment leakage. The bottom plate and can body are welded by mechanical welding process, which can be divided into external welding and internal welding. The external welding of PPH storage tank is a process that uses the imported automatic extrusion welding unit to realize the one-time welding molding of large welds at the stressed parts of the storage tank. The new PPH granular material with the same property as the tank body is hot melted at the large weld seam, and is integrated with the tank bottom and tank body. Internal welding is an automatic long arm extrusion welding process, which is an important step in all processes. Its principle is the same as external welding, but its equipment is different.

PPH storage tank vertical storage tank is a plastic storage tank made of PPH granular materials after processing. The barrel of PPH storage tank is made of PPH granules through extrusion and winding process, and the product is formed at one time without welding. PPH storage tank is made of polypropylene plate by welding. From the perspective of corrosion resistance, the corrosion resistance of PPH vertical storage tank is similar to that of PPH vertical storage tank. From the perspective of safety performance, the PPH tank cylinder is integrally formed without welding and leakage, while the PPH tank is welded, which is easy to cause leakage and increase unsafe factors. And there is a big gap between the other properties of the two, such as anti-aging performance. The nozzle installation is the last process, which is equivalent to the reduced version of bottom welding. That is, the imported small automatic extrusion welding unit is used to weld the connecting pipe and flange into shape, and then the hole opener is used to cut the corresponding caliber on the tank body, and then the domestic portable extrusion welding is used. PPH storage tanks are widely used in chemical, pharmaceutical, dye, chemical fiber, metallurgy, textile and other industries to store various corrosive media. The utility model has the advantages of long service life of corrosion resistance, light self weight, safe transportation, convenient maintenance, etc.

The main contents of cleaning the HDPE storage tank are as follows: at the end of each manufacturing, clean the surface of the HDPE container with fingers, and continuously clean the outside of the mechanical equipment with a large amount of water. Damage to the thermal insulation layer is strictly prohibited. According to the processing technology, the solution can be cleaned after a certain period of time. For a long time, more than 72 hours, machines and equipment should be cleaned again before class. It is forbidden to enter acid liquor into the bobbin of this commodity. If the cleaning box requires acid, do not use acid with pH<2. Once the acid enters the casing of this mechanical equipment, hydrogen effect will occur, and the surface will fall like a fish scale on a large scale. The general cleaning cylinder uses 2% of sodium hypochlorite solution and uses tap water to clean the cylinder. The HDPE tank shall be cleaned according to the requirements of Chinese standards. When entering the machine and equipment for cleaning, the water bottle should be padded at the bottom of the sponge pad to prevent special tools from falling in. Wear rubber shoes to prevent damage to the laminated glass. To sort out the actual staff, the records must be sorted out immediately to determine the work experience and the inspection and signature of the project.
