Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a bottom running track type cloth washing device for a filter press. Background Art

[0002] The filter press is a filtering equipment in the solid-liquid separation industry. The material enters the filter press through the pressure of the feed pump, and the particles in the filtrate are intercepted by the filter cloth, the filter medium, to form a filter cake in the filter chamber, and the filtrate is discharged from the discharge holes of the filter plate. During long-term use, the particles in the material will adhere to the filter cloth. As the particles accumulate, they will block the air holes of the filter cloth, making it difficult to discharge the filtrate and unable to form a filter cake, affecting normal production. For this reason, the filter cloth needs to be cleaned.

[0003] At present, the most commonly used method is the knocking method, that is, after the filtration is completed, the filter frame where the filter cloth is located is knocked with an iron rod to make large pieces of filter cake fall off, but it is impossible to completely remove all the filter cakes, and the continuous knocking method also damages the mechanical structure of the filter frame. Therefore, an efficient and lossless cleaning method is urgently needed by those skilled in the art. Summary of the invention

[0016] like Figure 1-3 , the marks in the figure are: walking track 1, walking wheel group 2, lower frame 3, upper frame 4, high-pressure water channel cross pipe 5, silt loosening agent cross pipe 6, high-pressure water nozzle 7, agent nozzle 8, joint 9, joint 10, silt loosening agent hose 11, high-pressure water hose 12, drag chain high-pressure pipeline 13, mobile end chain link 131, fixed end chain link 132, chain link 133, high-pressure pump 14, agent box 15, high-pressure pump 16, water tank 17.

[0017] Example: Figure 1 , 2As shown in , 3 , this embodiment specifically relates to a lower running track type cloth washing device for a filter press, including a running track 1, a running wheel group 2, a door-type frame, a drag chain type high-pressure pipeline, a high-pressure pump 14, a high-pressure pump 15, a water tank 17 and a medicine box 15.

[0018] like Figure 1 , 2 As shown in Figure 3, the running wheel group 2 is installed at the lower end of the door-type frame, and can slide on the running track 1. The running wheel group 2 includes a driving wheel and a driven wheel, wherein the driving wheel is driven by the running motor (omitted and not shown in the figure). The door-type frame includes a lower frame 3 and an upper frame 4. The lower frame 3 is a door-type structure, including vertical beams on both sides and a cross beam in the middle. The upper frame 4 is vertically slidably assembled on the vertical beams on both sides of the lower frame 3, forming a vertical lifting and sliding fit, and two horizontal pipes are arranged between the two lifting vertical beams of the upper frame 4, namely a high-pressure waterway cross pipe 5 and a silt loosening agent cross pipe 6. A number of high-pressure water nozzles 7 are arranged at intervals along the horizontal direction on the high-pressure waterway cross pipe 5, and a number of agent nozzles 8 are arranged at intervals along the horizontal direction on the silt loosening agent cross pipe 6. Through the lifting and lowering movement of the upper frame 4 on the lower frame 3, the full range of spray coverage of the filter cloth is achieved. It should be noted that in the actual structural selection, one of the vertical beams of the lower frame 3 and a corresponding lifting vertical beam in the upper frame 4 can be composed of a hydraulic cylinder to facilitate the realization of the lifting function.

[0019] like Figure 1 , 2 As shown in , 3 , the drag chain high-pressure pipeline 13 includes a plurality of mutually hinged links 133 , one end of the link connected in series by the links 133 is a movable end link 131 , and the other end is a fixed end link 132 , wherein the movable end link 131 is connected to the lower frame 3 , and the fixed end link 132 is fixedly connected to the end of the high-pressure pump 16 . Adjacent links 132 are hinged to adapt to bending and transformation at a certain angle. Two slots are provided in the cavity of the link 132, which are used to clamp the hoses set therein, specifically the silt loosening agent hose 11 and the high-pressure water hose 12. The silt loosening agent hose 11 extends outward at the fixed end and is connected to the medicine box 15 through the high-pressure pump 14, and the silt loosening agent hose 11 extends outward at the mobile end and is connected to the joint 9 of the silt loosening agent cross pipe 6. The high-pressure water hose 12 extends outward at the fixed end and is connected to the water tank 17 through the high-pressure pump 16, and the high-pressure water hose 12 extends outward at the mobile end and is connected to the joint 10 of the high-pressure waterway cross pipe 5.

[0020] like Figure 1 , 2As shown in Figure 3, the working method of the lower running track type cloth washing device for the filter press in this embodiment includes the following steps: water and silt loosening agent are respectively poured into the water tank 17 and the reagent box 15, and the silt loosening agent fully utilizes the active functions such as strong emulsifier and penetrant to quickly emulsify and decompose oil pollution and loosen silt; the door-shaped frame is driven to move longitudinally on the running track 1 by the running wheel group 2, and after it moves to within the working distance of the filter cloth, the high-pressure pump 14 and the high-pressure pump 16 are respectively turned on to pump the silt loosening agent in the reagent box 15 and the water in the water tank 17 at high pressure, and the silt loosening agent is passed through the mud. The sand loosening agent hose 11 is pumped into the sediment loosening agent horizontal pipe 6 and sprayed onto the filter cloth through the agent nozzle 8 to soften and decompose the sediment in the filter cake. After that, the high-pressure water is pumped into the high-pressure water channel horizontal pipe 5 through the high-pressure water hose 12 and sprayed onto the filter cloth through the high-pressure water nozzle 7 to disperse and drop the filter cake under high pressure; finally, the remaining filter cake residue is decomposed by the agent nozzle 8 and then cleaned by the high-pressure water nozzle 7 to achieve complete and efficient cleaning of the filter cake on the filter cloth; it should be noted that during the entire cleaning process, the upper frame 4 is controlled to perform continuous lifting operations.

[0021] The advantages of this embodiment are: by adopting a drag chain type high-pressure pipeline, the high-pressure water hose and the silt loosening agent hose can adapt to the longitudinal sliding of the portal frame; the portal frame adopts a lifting structure, which can make the high-pressure water nozzle and the silt loosening agent nozzle rise and fall to clean the entire area of ​​the filter cloth.
