Description

Circulating filtering belt type solid-liquid separator suitable for high-flow solid-liquid mixture Technical Field The invention relates to the technical field of solid-liquid mixture filtration, in particular to a circulating filtration belt type solid-liquid separator suitable for a high-flow solid-liquid mixture. Background In some large food processing enterprises, the material boiling processing time is long, but in order to ensure the material boiling effect, a material processing tank with a larger volume is generally not selected limitlessly, but a plurality of material processing tanks are selected to be respectively boiled for production and processing, and a plurality of processing tanks can be simultaneously processed when being respectively processed after the selection, so that more foods can be processed in unit time. In addition, by controlling the feeding and discharging time points of different material treatment tanks, operators can respectively treat feeding and discharging of different material treatment tanks in different time periods, so that the situation that the operators need to feed and discharge the material treatment tanks simultaneously in a short time is avoided, the labor intensity is too high, or the operators do not need to feed and discharge the material treatment tanks in a short time, and the utilization rate of the operators in the time is low is avoided. In the production mode, when the number of the material treatment tanks is large, the working time of operators can be fully utilized basically, and the working strength is not excessively high in a certain period of time. The material processing tank loading and unloading method comprises the following steps that after one material processing tank finishes loading and unloading and starts to start the material processing tank, the other material processing tank needs to be loaded and unloaded after a last material processing tank finishes loading and unloading and starts the material processing tank, and after the last material processing tank finishes loading and unloading and starts the material processing tank, the first material processing tank needs to be loaded and unloaded after the last material processing tank finishes loading and unloading, the first material processing tank needs to be loaded and unloaded again after the last material processing tank finishes loading and unloading and starting. However, in order to further improve the production efficiency, the production method needs to shorten the feeding and discharging time. The feeding and discharging operation comprises that an operator adds solid materials into a material treatment tank, a liquid adding pipe adds liquid materials into the material treatment tank, the operator removes the solid materials from the material treatment tank, a liquid discharging pipe respectively discharges the liquid materials mixed with a small amount of the solid materials out of the material treatment tank and conveys the liquid materials to subsequent treatment equipment for treatment through a pipeline, and the liquid discharging speed is required to be higher in order to ensure the liquid discharging speed because a large amount of liquid materials are contained in the tank body of the material treatment tank. In the process, the time required by operators in the feeding and discharging processes is reduced relatively limited, the time for adding liquid in the material treatment tank is related to the liquid adding speed of the liquid adding pipe, the time is related to a water supply company, the liquid discharging speed cannot be automatically improved, although the liquid discharging speed is in design of equipment pipelines, the discharged liquid is inevitably scattered in the liquid because part of steamed solid materials can be soft and rotten in the boiling process, and the liquid discharging pipeline from the material treatment tank to subsequent treatment equipment is long, so that the efficiency of the liquid discharging pipeline is influenced by the residual solid materials in the pipeline after a period of time is caused, the liquid discharging time of the material treatment tank is further increased, the feeding and discharging efficiency is reduced, the feeding and discharging time cannot be matched with the designed production rhythm due to the extension of the liquid discharging time, the labor intensity of operators in unit time is further increased, the production rhythm can only be slowed down, the production efficiency is further reduced, or the quantity of operators is increased, and the production cost is increased. In order to solve the problems, the prior art adopts the structure that after all liquid discharge pipes of all material processing tanks are gathered to a liquid discharge main pipe, a filtering tank is communicated, solid materials contained in liquid discharged by all material processing tanks are filtered through a filtering d
