Problems solved by technology

[0003] For example, the Chinese invention patent application (application number: 200410024976.9) discloses a new glass-lined reaction tank, which mainly includes an inner cylinder body, an outer jacket, a tank body, a glass-lined glaze layer, a jacket body, a head body, and a head piece. , which is characterized in that: the tank body includes an inner cylinder body and an outer jacket, the inner cylinder body is made of carbon steel, the inner wall is coated with a glass-lined glaze layer, the outer jacket is made of stainless steel, and the overall structure is directly welded to the inner cylinder body to form a Tank body, the glass-lined equipment uses an outer jacket to prevent the carbon steel inner cylinder from rusting. However, due to the problem of the glass-lined glaze layer bursting due to the welding of the outer jacket, the outer jacket of the glass-lined equipment cannot completely cover The entire outer surface of the inner cylinder body, resulting in localized rust during long-term use, which will eventually affect the hygiene of the clean workshop

Embodiment 1

[0037] like figure 1 , figure 2 As shown, a glass-lined equipment includes a cylinder body 1 and an insulation cover 2. The cylinder body 1 is integrally formed of carbon steel, and the insulation sleeve 2 is made of stainless steel and coated on the outside of the cylinder body 1. The insulation material 3 is filled therebetween, and the cylinder body 1 has a connecting portion 13, which is tubular and protrudes from the outer surface of the cylinder body 1. The inner surface of the cylinder body 1, the inner surface of the connecting portion 13 and the outer end surface of the connecting portion 13 are all Covered with a glass-lined layer 4; the connecting portion 13 is covered with a connecting flange 5 made of stainless steel, the connecting flange 5 is fixedly connected with the connecting portion 13, and its upper end surface is flush with the upper end of the connecting portion 13, and the glass-lined layer 4 is in contact with the upper end surface of the connecting ...

Embodiment 2

[0045] The structure of the glass-lined equipment is basically the same as that of Embodiment 1, the difference is that image 3 , Figure 4 As shown, the cylinder 1 includes an upper cylinder 11 and a lower cylinder 12, the upper cylinder 11 and the lower cylinder 12 are connected by bolts; the upper cylinder 11 has an upper high neck flange 111, and the lower cylinder 12 has It has a lower high-neck flange 121, the end faces and outer surfaces of the upper high-neck flange 111 and the lower high-neck flange 121 are covered with a glass-lined layer 4, and the upper cylinder 11 is set with a stainless steel cover. The upper transition ring 112, the lower cylinder body 12 is covered with a lower transition ring 122 made of stainless steel, the upper transition ring 112 abuts against the upper end surface of the upper high neck flange 111, the upper transition ring 112 and the upper cylinder body 11 Fixedly connected, the lower transition ring 122 abuts against the lower end su...

Abstract

The invention discloses a glass lining device and a production method thereof and belongs to the technical field of medical and chemical instruments. The glass lining device can be used for solving the problem that parts of an existing glass lining device easily rust. The glass lining device comprises a barrel body made of carbon steel and a thermal insulating sleeve made of stainless steel, wherein the thermal insulating sleeve is wrapped outside the barrel body; the space between the barrel body and the thermal insulating sleeve is filled with a thermal insulating material; a pipe connecting part is arranged on the barrel body; all the inner surface of the barrel body and the inner and outer surfaces of the pipe connecting part are covered with glass lining layers; the pipe connecting part is sleeved by a pipe connecting flange disc made of stainless steel; the pipe connecting flange disc and the pipe connecting part are fixedly connected; the thermal insulating sleeve and the outer side surface of the pipe connecting flange disc are fixedly connected by virtue of welding. According to the glass lining device, the sanitary requirement of the glass lining device with the carbon steel barrel body can be improved.

Description

technical field [0001] The invention belongs to the technical field of medical chemical equipment, and relates to glass-lined equipment and a manufacturing method thereof. Background technique [0002] Glass-lined equipment is a kind of enamel with high silicon content coated on the metal surface, and fired at 950 ° C to make the enamel adhere to the surface of the metal iron tire (low carbon steel), so it has chemical stability similar to glass and metal The double advantage of strength. Glass-lined equipment is widely used in reaction, evaporation, concentration, synthesis, extraction, polymerization, saponification, mineralization, chlorine Nitrification, nitrification, etc., to replace expensive stainless steel and non-ferrous metals. Glass-lined equipment mainly includes reaction tanks, storage tanks, distillation tanks, condensers, etc., which have strong corrosion resistance to various concentrations of inorganic acids, organic acids, organic solvents and weak alkal...
