Description

Technical Field

[0001] The utility model relates to the technical field of chemical barrels, in particular to a chemical barrel for containing chemical reagents. Background Art

[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are an important condition for scientific and technological progress and are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. At present, chemical reagents are usually stored in chemical barrels, but some chemical reagents are prone to precipitation during the storage process, and the precipitates condense together, affecting the use effect of liquid chemical reagents.

[0003] For example, Chinese patent announcement No. CN213200660U discloses a chemical barrel for containing chemical reagents. When in use, the chemical reagents are conveniently placed into the inner tank through the liquid inlet pipe, the chemical reagents in the inner tank are conveniently taken out through the liquid extraction pipe, and the impurities in the inner tank are conveniently discharged through the sewage pipe. The driving shaft on the driving motor drives the screw on the coupling to continuously stir the chemical reagents in the inner tank, so that the chemical reagents rotate continuously, which effectively prevents the chemical reagents from precipitating. The thermal insulation layer is made of polystyrene foam board, which has a good thermal insulation effect, can prevent the heat loss in the inner tank, and is convenient for keeping the reagents in the inner tank warm.

[0004] However, the chemical reagents in the above application are contained in chemical barrels. After the chemical raw materials inside are stirred or even stored in heat preservation for a long time, the internal pressure of the chemical barrel may increase. If the pressure is not relieved, the chemical barrel may explode, which poses certain installation risks.

[0005] For this reason, we urgently need to provide a chemical barrel for storing chemical reagents. Utility Model Content

[0006] The purpose of the utility model is to provide a chemical barrel for containing chemical reagents, so as to solve the problem that the chemical barrel for containing chemical reagents proposed in the above-mentioned background technology may cause the internal pressure of the chemical barrel to increase after the chemical raw materials inside are stirred or even stored in heat preservation for a long time.

[0008] The pressure relief device includes a liquid storage tank, a pressure relief pipe, a strong spring, a sealing piston, and an exhaust pipe. The liquid storage tank is installed on the top of the right outer surface of the chemical barrel, the pressure relief pipe is fixedly connected to the top of the right outer surface of the chemical barrel, and its left end extends into the interior of the liquid storage tank. The strong spring is installed on the right inner wall of the pressure relief pipe, the sealing piston is fixedly connected to the left end of the strong spring, and the exhaust pipe is fixedly connected to the bottom right side of the pressure relief pipe.

[0009] A further improvement is that the diameter of the sealing piston is the same as the inner diameter of the pressure relief pipe and is slidably connected to the inner wall of the pressure relief pipe. When the pressure inside the chemical barrel is too high, the strong air pressure pushes the sealing piston to the right side of the pressure relief pipe and squeezes the strong spring until the sealing piston moves to the right side of the exhaust pipe. The pressure inside the chemical barrel is released to the inside of the liquid storage tank through the exhaust pipe, and the pressure relief is automatically completed, avoiding excessive pressure inside the chemical barrel and causing it to explode.

[0010] A further improvement is that a liquid injection pipe is fixedly connected to the top of the right outer surface of the liquid storage tank, and a liquid discharge pipe is fixedly connected to the bottom of the right outer surface of the liquid storage tank. Electric sealing valves are respectively installed on the outer surfaces of the liquid injection pipe and the liquid discharge pipe. The solvent is added to the interior of the liquid storage tank through the liquid injection pipe, and the waste liquid inside the liquid storage tank is regularly discharged and replaced through the liquid discharge pipe.

[0011] A further improvement is that the interior of the liquid storage tank is filled with a solvent, and an observation window is installed on the front of the liquid storage tank. The observation window is made of transparent tempered glass. Different solvents or water can be added to the interior of the liquid storage tank according to the different chemical raw materials stored in the chemical barrel. The usage of the solvent in the liquid storage tank can be observed in real time through the observation window, which is convenient for timely replacement.

[0012] A further improvement is that the stirring device includes a stirring motor, a sealed bearing, a stirring shaft, and a stirring rod. The stirring motor is installed at the top center of the chemical barrel, the sealed bearing is installed inside the top center of the chemical barrel, the stirring shaft is connected to the output end of the stirring motor, and is rotatably connected to the inside of the sealed bearing, and the bottom extends into the bottom of the inside of the chemical barrel, five groups of stirring rods are vertically and equidistantly fixed to the outer surface of the stirring shaft, and the stirring motor is started regularly to drive the stirring shaft to rotate inside the sealed bearing, thereby driving the stirring rod on the outer surface of the stirring shaft to rotate, thereby stirring and mixing the raw materials inside the chemical barrel to avoid precipitation of the chemical raw materials inside.

[0013] A further improvement is that a feed pipe is fixedly connected to the left side of the top of the chemical barrel, a discharge pipe is fixedly connected to the bottom of the left outer surface of the chemical barrel, and a pressure gauge is installed on the right side of the top of the chemical barrel. Chemical raw materials are introduced into the interior of the chemical barrel through the feed pipe and discharged for use through the discharge pipe, and the pressure gauge provides real-time feedback of the pressure conditions inside the chemical barrel.

[0014] A further improvement is that electric sealing valves are also installed on the outer surfaces of the feed pipe and the discharge pipe, and the chemical barrel and the liquid storage tank are sealed by the electric sealing valve to prevent liquid from leaking.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
