Abstract
The utility model discloses a stainless steel composite spherical digester, which comprises a bracket, a spherical digester, a transmission part, an air inlet, an air outlet, an air inlet pipe and a blow pipe, wherein a spherical shell is formed by compounding an outer carbon steel layer and an inner stainless steel layer. The stainless steel composite spherical digester is simple in structure, the inner layer of the spherical shell is the stainless steel layer and has the advantages of corrosion resistance 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 application environment and the application range of the spherical digester are greatly improved, and the service life of the spherical digester is prolonged. Compared with a carbon steel spherical digester, the stainless steel composite spherical digester has the advantages of high corrosion resistance, wide application range and excellent performance; and compared with a pure stainless steel spherical digester, the stainless steel composite spherical digester has the advantages of reducing the cost by 50 percent and having the same using effect and service life, so that the market application range is increased, the application prospect is wide, and the stainless steel composite spherical digester is applied to multiple fields such as pharmacy, chemical fiber, biochemical engineering, environment friendliness and wholesome food expanded from the traditional paper-making and pulping industry.
Description
Technical field
The utility model relates to a kind of paper-making pulping equipment, specifically, relates to the compound rotary spherical digester of a kind of stainless steel.
Background technology
Along with the development of the economic diversification of China, to improving constantly of the technology standards that become more meticulous such as manufacturing product quality, safety, environmental protection, health.Simultaneously, China rotary spherical digester production marketing market in continuous expansion, to using decay resistance and security performance requirements at the higher level are proposed all, progressively to high-end, development becomes more meticulous.Applying unit is also developed to the centralized production type by original dispersion type of production, and the demand of equipment is developed to concentrating big quantity to purchase by original dispersion smallest number buying.Especially; In investigation, find that China numerous paper-making pulping enterprise adopts Ammonium Sulfite Method production slurrying more, and use rotary spherical digester production industry used medium, serious to the rotary spherical digester wall erosion that the general steel plate manufacturing is produced; Significantly reduce rotary spherical digester service life, and have potential safety hazard.
Summary of the invention
The purpose of the utility model is exactly to prior art problems and deficiency, the compound rotary spherical digester of the stainless steel that provides a kind of decay resistance and security performance all to be improved.
Technical scheme: the compound rotary spherical digester of a kind of stainless steel, comprise support, rotary spherical digester, running part, and air inlet and gas outlet, air inlet pipe and blow-off pipe, spherical shell are that outer carbon steel layer and internal layer stainless steel layer are composited.
Between the inside and outside layer of spherical shell, also be provided with thermal insulation layer.
Beneficial effect: the utility model simple in structure, the spherical shell internal layer is that stainless steel layer has anticorrosive and wear-resisting advantage, thereby reduces cost.This composite construction is that rotary spherical digester has been discharged potential safety hazard, has improved the rotary spherical digester environment for use and the scope of application greatly, has prolonged service life.Compare with the carbon steel rotary spherical digester, it is strong to have corrosion resistance, and the scope of application is wide, and performance is more excellent; Compare with pure stainless steel rotary spherical digester; Cost has reduced by 50%; And result of use and service life equal advantage, scope of application development in market is increased day by day, the purposes prospect very extensively; Use from traditional paper-making pulping industry, be extended to pharmacy, chemical fibre, biochemical industry, environmental protection, a plurality of fields of wholesome food.
