[0002] At present, chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering", etc. Any technology that uses chemical methods to change the composition and structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical technology. The resulting products are called chemicals or chemical products. Most chemical liquids are highly corrosive and need to be stored in plastic storage tanks with good anti-corrosion properties.

[0003] Among them, plastic storage tanks are made of pure polyethylene and are integrally formed using a rotational molding process. They have the advantages of no welding, no leakage, non-toxicity, light weight, anti-aging, impact resistance and long life. They can store and react with most inorganic acids, alkalis, salt solutions and most organic solvents. They are ideal storage containers for reactive chemical solutions and clean solutions.

[0004] However, there are still some shortcomings in the use of plastic storage tanks on the market; the weight of the chemical liquid inside the plastic storage tank cannot be detected, resulting in a large liquid capacity inside the plastic storage tank, causing the bottom of the plastic storage tank to be subjected to excessive pressure, causing the outer wall of the plastic storage tank to rupture. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0007] The quantitative storage mechanism includes plastic storage tanks that are detachably installed in the four groups of the first positioning grooves, suction pipes that are connected and installed at the bottom of the four groups of plastic storage tanks, a steel barrel that is detachably installed in the second positioning groove, and a liquid pump that is connected and installed at the top of the steel barrel.

[0008] As an optional solution of the technical solution of the present application, the inlet end of the liquid pump is connected and installed with a tap, and the tap interfaces are respectively connected and installed with multiple groups of the suction pipes.

[0010] As an optional solution to the technical solution of the present application, a base is fixedly installed on the bottom side of the outer barrel, and a plurality of groups of equidistantly distributed docking grooves are provided on the top of the base. The plurality of groups of docking grooves respectively correspond to the four groups of plastic storage tanks and the bottom of the steel barrels, thereby supporting the plastic storage tanks and the steel barrels.

[0011] As an optional solution of the technical solution of the present application, pressure sensors are fixedly installed inside the multiple groups of docking grooves, and the multiple groups of pressure sensors correspond to the four groups of plastic storage tanks and the bottom of the steel barrel respectively, so as to detect the weight of the plastic storage tanks.

[0012] As an optional solution of the technical solution of the present application, a plurality of groups of equally spaced reinforcement hoops are fixedly installed on the outer walls of the four groups of plastic storage tanks, and connecting frames are fixedly installed between the corresponding reinforcement hoops, so as to reinforce the plastic storage tank machine.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application is to install four groups of equidistantly distributed plastic storage tanks inside the outer barrel and support them in the docking grooves on the top of the base, so that the plastic storage tanks can still remain inside the outer barrel in the event of leakage. At the same time, with the pressure sensors installed in the multiple groups of docking grooves, the real-time pressure monitoring of the plastic storage tanks is carried out. When the weight of the plastic storage tank is greater than the set value of the pressure sensor, the signal will be transmitted to the control processor to control the liquid pump and the solenoid valve in the quantitative storage mechanism to transport the chemical liquid inside the plastic storage tank that exceeds the weight into the steel barrel, so as to avoid excessive pressure inside the plastic storage tank and cause the plastic storage tank to burst.

[0015] 2. The technical solution of the present application has four groups of plastic storage tank outer walls with multiple groups of equally spaced reinforcement hoops fixedly installed, and connecting frames are fixedly installed between the corresponding reinforcement hoops. When the plastic storage tank is filled with a large amount of chemical liquid, the reinforcement hoops installed on the outside of the connecting frame can support the outer wall of the plastic storage tank to improve the loading capacity of the plastic storage tank.
