Breathing apparatus for normal pressure storage tank

Abstract

The invention discloses a breathing apparatus for a normal pressure storage tank, which relates to a self-cleaning type breathing apparatus. The breathing apparatus is arranged on the top of the normal pressure storage tank and comprises a fan blade box internally provided with fan blades and a driving mechanism thereof, a sliding bearing connecting mechanism in driving connection with the fan blades, a pass burble spiral scraper in driving connection with the sliding bearing connecting mechanism, a ventilating pipe group running through the mechanism and a ventilating pipe of the normal pressure storage tank, wherein the pass burble spiral scraper is formed by forming micropores on a burble spiral scraper. The breathing apparatus for the normal pressure storage tank adopts the self-cleaning breathing apparatus which is driven by wind energy and has self-cleaning function to achieve the aims of ensuring the balance between the pressure in the tank and the atmospheric pressure in the process of lifting the liquid surface in the storage tank, preventing breathing holes and pipelines from being blocked, improving the anti-explosion and corrosion resisting capabilities, and simultaneously improving the safe using rate of the apparatus, and reducing the production and maintenance cost.

Description

technical field [0001] The invention relates to a safety device for an atmospheric pressure storage tank, in particular to a wind energy self-cleaning atmospheric pressure storage tank breathing device for chemical and pharmaceutical manufacturing enterprises. Background technique [0002] In order to ensure the balance between the tank and the atmospheric pressure during the rise and fall of the liquid level in the storage tank, that is, to protect the normal transportation of equipment and materials, and to play a safety role, domestic large and medium-sized coal and petrochemical companies often use chemical and chemical raw materials in storage tanks, etc. The tank body (mostly the tank top) of the atmospheric pressure storage tank is equipped with breathing holes, pipe equipment, etc. [0003] However, due to the characteristics of the storage medium of chemical and chemical raw material storage tanks, such as tar, ammonia water and other organic media, the volatile com...

AI Technical Summary

Problems solved by technology

[0013] In order to solve the problem of easy clogging of breathing devices (holes and tubes) of atmospheric storage tanks with complex components in existing coal chemical enterprises, and easy adhesion of materials on the inner wall of breathing tubes, and to prevent direct damage to the main structure of the storage tanks, explosion-proof, anti-explosion Explosion and other problems, the object of the present invention is to: provide a kind of normal pressure storage tank breathing device, the normal pressure storage tank breathing device adopts the breathing device of the self-cleaning function of the wind energy transmission of natural cleanness, thus reaches to ensure the liquid in the storage tank The balance between the tank and the atmospheric pressure during the surface lifting process prevents the blockage of breathing holes and pipes, improves the explosion-proof and corrosion-resistant capabilities, and at the same time improves the safe use of equipment and reduces production and maintenance costs.
