Description

Mortar pipe filter equipment Technical Field The invention relates to the technical field of mortar conveying and pipeline filtering, in particular to a mortar pipe filtering device. Background In the multi-wire cutting process of silicon wafers, the mortar is usually required to be continuously conveyed to a construction position through a pipeline. Because the mortar contains a certain proportion of aggregate particles, agglomerated particles and impurities mixed in the construction process in addition to the liquid phase, a filtering structure is usually required to be arranged in a conveying path before the mortar enters a subsequent spray nozzle, valve or fine pipeline so as to reduce the adverse effect of larger particles, agglomerations and metal impurities on subsequent components. The filtering structure in the existing mortar pipeline mostly adopts a filter screen, a filter cylinder or a filtering piece directly arranged at the joint to complete interception. Such a structure is capable of screening mortar passing through the pipeline to a certain extent in practical use, but larger particles, agglomerates and high-density impurities in the mortar tend to directly impact the filtering part and gradually accumulate in the filtering area. With the prolonged service time, the local flow resistance of the filtering part can be gradually increased, so that the conveying continuity is affected, the filtering area is blocked when serious, and the shutdown maintenance frequency is increased. In order to solve the above problems, there is a conventional technology in which the filtering function is maintained by enlarging the filtering area, increasing the strength of the filter, or periodically disassembling and cleaning. According to the scheme, the failure of the filter element can be delayed under a certain condition, but under the continuous mortar conveying working condition, heavier impurities and larger particles still concentrate near the filtering part at first, and the load born by the filtering area is not effectively split. When a large amount of particles and adhesion substances are adhered to the outer surface of the filter element, the filter element is detached and cleaned simply after stopping, and often can only be treated after the blockage is formed, so that the maintenance timeliness is limited. Another type of problem exists with existing filter structures during the unpick and wash maintenance phase. When the part of the structure is disassembled, the filtering piece is required to be directly taken out of the pipeline, in the process, residual mortar liquid and trapped impurities inside and outside the filtering piece are easy to leak or fall back, so that maintenance pollution is increased, and the trapped particles can possibly reenter the main pipeline or the peripheral part. For the mortar working condition with liquid residue and adhesive particles, if the disassembling and cleaning action lacks a controlled closing and flow path switching process, once the filter element is disassembled, unordered migration of internal attachments and in-bin sediments is easy to occur. In addition, although the part of the filtering structure in the prior art can be manually disassembled and washed, the disassembling and washing action is usually only to take out the whole filtering piece and then to wash the outside, and the matching structure for performing back flushing and mechanical cleaning on the filtering area before disassembling is absent. For fine particles and an adhesive layer attached to the filtering surface or near the filtering holes, the filter is difficult to separate from the working position in time only by external disassembly and cleaning, so that the filter is still easy to reenter into a high-resistance state in a short time after being reloaded, and the repeated use effect is affected. Therefore, it is still necessary to provide a mortar pipe filter device, which not only can pre-separate heavier impurities before mortar enters a filtering area, and form a step-by-step filtering path from outside to inside in a filtering stage, but also can finish bottom sealing and flow path switching in a disassembling and washing stage, and then perform back flushing on the filtering area by utilizing residual liquid in the interior, and realize controlled maintenance by matching with mechanical cleaning, so as to solve the problems of concentrated load of filtering parts, easy falling back of dirty liquid and impurities during disassembling and washing and unstable maintenance effect in the prior art. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides a mortar pipe filtering device to solve the problems. The aim of the invention is realized by the following technical scheme: the utility model provides a mortar pipe filter equipment, including the mortar pipe, the intraductal fixedly connected with fixed bolster of mortar, the position
