Description

Technical Field

[0001] The utility model relates to the technical field of a desanding pump for paper pulp, in particular to a desanding pump for transporting paper pulp. Background Art

[0002] As we all know, in the process of pulp production and transportation, the treatment of impurities such as sand particles and fiber agglomerates has always been a difficult problem. These impurities will not only directly affect the quality of paper, such as causing uneven surface and reduced strength of paper, but also cause wear on production equipment, increase maintenance costs, and even lead to production interruptions. Existing filter components often use a single filter material and a fixed design, which is difficult to effectively intercept impurities of various sizes. Especially under high-concentration pulp flow conditions, the filtering effect is even more insufficient. The disassembly and cleaning process of traditional filtration systems is complicated and time-consuming, and requires professional operation, which increases production costs and downtime. In severe cases, equipment failure may occur due to improper maintenance. Most existing equipment lacks effective flow monitoring methods and cannot detect problems such as filter blockage in time, resulting in reduced production efficiency and unstable product quality. In addition, manual operation is frequent, which not only increases labor costs, but also reduces production efficiency and safety. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content
