Expansion-prevention plastic chemical barrel

Abstract

The invention provides an expansion-prevention plastic chemical barrel. The expansion-prevention plastic chemical barrel is characterized by comprising a barrel cover and a barrel body; a pressure release hole is formed in the top of the barrel body; a pressure release valve is arranged on the pressure release hole; the lower portion of the barrel body is provided with a pressure gauge and a warning display lamp; a control device is arranged on the surface of the barrel body; and the control device is connected with the pressure gauge, the warning display lamp and the pressure release valve through circuits. The pressure gauge is arranged on the expansion-prevention plastic chemical barrel and can monitor the pressure in the chemical barrel in real time, once the pressure in the chemical barrel exceeds a warning value, the control device triggers a warning, the warning display lamp flickers, meanwhile, the pressure release valve is opened to release pressure, the pressure in the chemical barrel can reach a normal value, the phenomenon that the chemical barrel expands or even explodes along with rising of the temperature of the external environment in the chemical raw material storage and transportation process is avoided, and potential safety hazards are eliminated; and the inner wall of the barrel body is provided with an anticorrosive coating so that the barrel body can be protected against corrosion of chemical raw materials in the barrel, and the service life of the chemical barrel is further prolonged.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an anti-expansion plastic chemical barrel. Background technique [0002] Chemical barrel is a container used to hold chemical raw materials, widely used in chemical enterprises. At present, most of the chemical raw materials are packaged in general open plastic barrels or stainless steel barrels. The inside of such plastic barrels cannot withstand pressure and is prone to deformation, aging and rupture. However, some chemical raw materials will evaporate due to the high ambient temperature, changing from liquid to gas, which will increase the air pressure in the closed environment, eventually causing the barrel to expand or even explode. It brings potential safety hazards to the storage and transportation of chemical raw materials. Contents of the invention [0003] In order to solve the above existing problems, the object of the present invention is to provide an ...

Problems solved by technology

At present, most chemical raw materials are packaged in general open plastic barrels or stainless steel barrels. The inside of such plastic barrels cannot withstand pressure and is prone to deformation, aging and rupture.

However, some chemical raw materials will evaporate due to high ambient temperature and change from liquid to gas, which will increase the air pressure in the closed environment and eventually cause the barrel to expand or even explode.
