Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage tanks, in particular to an acid-resistant lining of a plastic storage tank. Background Art

[0002] Chemical containers are commonly used equipment in chemical production. In some cases, the medium in the container has a strong corrosive effect. In order to prevent the container from being corroded by the medium, the container is required to be made of expensive corrosion-resistant materials. When the container is also under pressure, the container is required to have sufficient wall thickness, which increases the manufacturing cost of the container. Using ordinary carbon steel as the pressure shell and lining the engineering plastic anti-corrosion lining container can solve this problem well.

[0003] For example, a polytetrafluoroethylene lining of a chemical container with a publication number of CN209791521U includes a lining layer and a lining flange, wherein the lining layer is adhered to the inner wall of the container cylinder, and the lining flange is attached to the container flange, wherein an embedded anchor is embedded in the outer surface of the lining layer, and the embedded anchor is composed of an adhesive disc and an anchor claw, wherein the outer surface of the adhesive disc is exposed from the outer surface of the lining layer, and the anchor claw is embedded in the lining layer and does not appear from its inner surface; the adhesive disc and the anchor claw are fixedly connected. The embedded anchors are basically evenly distributed on the outer surface of the lining layer. Since the outer surface of the polytetrafluoroethylene lining is distributed with embedded anchors embedded in the lining layer, and these embedded anchors have adhesive discs made of metal, the lining layer can be firmly bonded to the inner wall of the container cylinder through the adhesive discs of these embedded anchors, thus converting the problem into bonding between metal and metal.

[0004] The above technical solution has some problems in practical application. The installation and disassembly of the lining in this technical solution is relatively complicated, and it is not convenient to replace and maintain. In addition, the sealing effect of the lining joint is general, and it is difficult to ensure its acid and penetration resistance.

[0005] Therefore, it is necessary to invent an acid-resistant lining for plastic storage tanks to solve the above problems. Utility Model Content
