Negative pressure moisture absorption storage tank

Abstract

The invention discloses a negative pressure moisture absorption storage tank, and relates to the technical field of novel storage tanks. The storage tank comprises a storage tank body, one side of the storage tank body is fixedly connected with a negative pressure pumping and discharging pipe, the top end of the storage tank body is fixedly connected with a sealing cover, one side of the top end of the sealing cover is fixedly connected with an internal expansion prevention opening structure, and the other side of the top end of the sealing cover is fixedly connected with two convenient-to-replace damp-proof block carrying structures. According to the storage tank, through the design of the internal expansion prevention opening structure, pre-filling of mixed gas in the tank is conveniently completed in the tank opening process, a pre-opening support in the tank is formed, expansion explosion with different pressure intensities generated by direct opening in the tank is avoided, and the use safety of the tank is greatly improved; and through the design of the convenient-to-replace damp-proof block carrying structures, the tank can conveniently complete carrying placement of damp-proof blocks of different sizes, and the damp-proof blocks are convenient to replace.

Description

technical field [0001] The invention relates to the technical field of novel storage tanks, in particular to a negative pressure moisture-absorbing storage tank. Background technique [0002] With the rapid development of society, in order to facilitate the preservation of food, vacuum preservation technology is applied to daily life. The negative pressure moisture absorption storage tank fundamentally solves the problem, ensuring low oxygen and low pressure inside the container, forming a true vacuum preservation, but , In the existing device, the air pressure in the tank is not restored during the opening process, and the overall is too low, resulting in the cover being absorbed during the application process and making it difficult to open, and there is an air pressure gap and the inside of the tank is easy to expand. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a negative pressure moisture-absorbing storage tank to...

Problems solved by technology

[0003] The purpose of the patent of the present invention is to provide a negative pressure moisture-absorbing storage tank to solve the existing problem: in the opening process of the existing device, due to the lack of recovery of the air pressure in the tank, the whole is too low, resulting in the overall failure in the application process. The middle cover is absorbed and it is not easy to open, and there is an air pressure gap and the inside of the tank is easy to expand
