Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization pumps, in particular to a corrosion-resistant and wear-resistant desulfurization liquid delivery pump. Background Art

[0002] The desulfurization pump is a corrosion-resistant pump, mainly used for conveying corrosive liquids. It is a widely used pump among general equipment pumps and can adapt to various working conditions, such as conveying acid, alkaline clear liquid or slurry, various corrosive slurries in the smelting industry, various dilute acids in the sulfuric acid industry, and various sewage in the environmental protection industry. The pump is both corrosion-resistant and wear-resistant, and has a wide range of uses. Common materials for desulfurization pumps are plastic pumps and metal pumps. The flow-through material is required to be wear-resistant, corrosion-resistant, impact-resistant, and temperature-resistant (generally -20 degrees to 90 degrees Celsius). The north requires that the mechanical seal has no external cooling water system, and the pump body provides self-cooling.

After the pump body has been operating for a long time, the coating is prone to wear and thinning and needs to be maintained. The existing maintenance method is to replace the pump body, which increases the expenditure of manpower and economic costs. In order to realize the convenient removal and replacement of the anti-corrosion and wear-resistant coating inside the pump body, the present invention makes the following improvements.

A liquid inlet pipe 44 is fixedly provided inside the front protective plate 42, and one end of the liquid inlet pipe 44 passes through the front cover 22 and extends to one side of the front cover 22. One end of the liquid inlet pipe 44 located on the side of the front cover 22 is threadedly connected to a blocking ring 45. The top surface of the annular shell 21 is threadedly connected to a liquid outlet pipe 46.

[0030] Example 2

[0031] Based on Example 1, please refer to Figure 1 、 Figure 2 and Figure 4 As shown, in order to facilitate the removal and replacement of a single blade 62 or axle 61, the specific improvements are as follows:
