Explosion-proof type chemical raw material premixing equipment

Abstract

The invention discloses explosion-proof type chemical raw material premixing equipment. The equipment comprises a shell and a seal cover arranged on the shell, wherein supporting legs are arranged atthe bottom of the shell, and floor pins are arranged at the bottoms of the supporting legs; a lower flange and an upper flange are respectively arranged on the joint of the shell and the seal cover; aseal groove is formed in the top of the lower flange; a seal bar corresponding to the seal groove is arranged at the bottom of the upper flange; the lower flange and the upper flange are fastened through a screw; a motor is arranged in the middle of the top of the seal cover; a filter screen is arranged inside an exhaust pipe; a piston board is arranged at the top of the filter screen, a spring is connected to the top of the piston board, and the piston board can be lifted freely inside the exhaust pipe; the top end of the spring is fixedly connected with the exhaust pipe; and an exhaust holeis formed in the side wall of the exhaust pipe at the top of the filter screen. The equipment ensures the internal pressure in a safe range, effectively prevents explosion, and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an explosion-proof chemical raw material premixing equipment. Background technique [0002] The relationship between human beings and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing and transportation to spiritual life such as culture, art and entertainment, chemical products are required to serve them. Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. The lives of ancient people depended more on the direct utilization of natural substances, or extracting needed things therefrom. Because the inherent properties of these substances cannot meet people's needs, various proce...

Problems solved by technology

[0003] Chemical raw material premixing equipment has a very wide range of applications, and it needs to be released in time, otherwise there will be a danger of explosion. The structure of traditional chemical raw material premixing equipment is relatively complicated, and the mixing efficiency is difficult to guarantee. In addition, it lacks a pressure relief mechanism, which has a certain degree of safety. Hidden danger
