Composite stainless steel spherical digester

Abstract

The invention discloses a composite stainless steel spherical digester which comprises a bracket, a spherical digester body, a transmission part, an air inlet, an air outlet, an air inlet pipe and a blowing pipe, wherein the spherical shell body is formed by compounding an outer carbon steel layer and an inner stainless steel layer. The stainless steel spherical digester is simple in structure, and the inner layer of the spherical shell is a stainless steel layer and has the advantages of high corrosion and wear resistance, so that the cost is reduced. According to the composite structure, the potential safety hazard of the spherical digester is eliminated, the service environment and the application range of the spherical digester are greatly improved, and the service life is prolonged. Compared with a carbon steel spherical digester, the composite stainless steel spherical digester has high corrosion resistance, a wide application range and an excellent performance; compared with a pure stainless steel spherical digester, the composite stainless steel spherical digester has the advantages that the cost is reduced by 50 percent, and the service effect and the service life are equal, so that the market application range is increasingly widened, the application prospect is wide, and the application is extended from the traditional papermaking and pulping industry to multiple fields of pharmacy, chemical fiber, biochemical engineering, environment friendliness and sanitary food.

Description

technical field [0001] The invention relates to a papermaking and pulping equipment, in particular to a stainless steel composite steaming ball. Background technique [0002] With the development of my country's economic diversification, the product quality, safety, environmental protection, hygiene and other refined process standards of the manufacturing industry have been continuously improved. At the same time, the sales market of steamed ball products in my country is constantly expanding, and higher requirements are put forward for the use of corrosion resistance and safety performance, and they are gradually developing towards high-end and refined products. The user unit has also developed from the original decentralized production type to the centralized production type, and the demand for equipment has developed from the original scattered small-quantity procurement to centralized large-quantity procurement. In particular, during the investigation, it was found that...

Problems solved by technology

In particular, during the investigation, it was found that many papermaking and pulping enterprises in my country mostly use the ammonium method to produce pulp, and use the medium used in the production of steamed ball products, which seriously corrodes the wall of steamed balls produced by ordinary steel plates, greatly reducing the service life of steamed balls. And there are security risks
