Description

Technical Field

[0001] The present application relates to the technical field of filter cloth cleaning equipment, and in particular to a composite filter cloth cleaning filter tank aeration backwashing equipment. Background Art

[0002] Filter cloth is a porous material used for solid-liquid separation or gas-solid separation. Through its unique structure and material properties, it allows liquid or gas to pass through and intercepts solid particles, thereby achieving the purpose of material separation. It is widely used in many industrial fields, especially in the field of environmental protection (including air pollution, garbage and sewage treatment). The filter cloth industry has gradually become a key development project supported by the state.

[0003] However, during the long-term use of the filter cloth, as the solid particles filtered by it increase, they will gradually accumulate on the surface of the filter cloth and even enter the filter pores thereon, causing blockage, thereby reducing the filtering effect of the filter cloth. Therefore, the filter cloth needs to be backwashed and cleaned after long-term use to ensure its good filtering effect. However, when the existing backwashing equipment is used to clean the filter cloth, the water flow is very likely to spread around the filter cloth, making it difficult to clean out the solid particles stuck in the filter pores, thereby resulting in poor backwashing cleaning effect for the filter cloth, and low stability and reliability.

[0004] Therefore, there is an urgent need for a backwashing cleaning device for filter cloth to solve the defects of the above-mentioned existing backwashing cleaning equipment during actual use. Summary of the Invention

[0005] The present application proposes a composite filter cloth cleaning filter tank aeration backwashing equipment, which has the advantages of being able to effectively clean out solid particles stuck in the filter cloth filter holes, so that it has a better backwashing cleaning effect on the filter cloth, and has high stability and reliability. It is used to solve the problem that when the existing backwashing equipment is cleaning the filter cloth, the water flow is very easy to spread around the filter cloth, making it difficult to clean out the solid particles stuck in the filter holes, thereby resulting in poor backwashing cleaning effect on the filter cloth.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a composite filter cloth cleaning filter tank aeration backwashing equipment, including a cleaning box body with an arc-shaped curved surface structure on one side of the inner wall, the bottom of one side of the end of the cleaning box body is provided with a sewage pipe connected to its inner cavity for discharging backwash sewage, and a hollow shaft is fixedly installed on the inside of the cleaning box body passing through it on the left and right, and one end of the hollow shaft is connected to the flushing water pipe, and the flushing water can be transported to the inner cavity of the cleaning box body through the hollow shaft, and an aeration component connected to the inner cavity of the hollow shaft is provided on the top of the outer surface of the hollow shaft and located in the inner cavity of the cleaning box, so that the flushing water discharged through the aeration component contains a large number of bubbles to further improve its backwashing effect, and a group of power components for squeezing the end of the filter cloth are respectively provided on both sides of the outer surface of the hollow shaft, and the power component includes a positioning sleeve movably sleeved on the outer surface of the hollow shaft and located in the inner cavity of the cleaning box, one end of the positioning sleeve on the right side is transmission-connected to the rotating motor fixedly installed on the other side of the end of the cleaning box body, and a A linear motor with an annular clamping block is fixedly installed at the output end, and under the action of the linear motor, the annular clamping block can be driven to move left and right along the trajectory of the central axis of the positioning sleeve to squeeze or move away from the end of the filter cloth. An expansion ring sleeve for flattening the filter cloth and wrapping the aeration component therein is provided between the corresponding ends of the two groups of positioning sleeves. The expansion ring sleeve is provided with a groove along one side of its generatrix, and a splint with an end movably connected to the outer surface of the positioning sleeve is provided on the groove, and the splint and the expansion ring sleeve are connected by an elastic member fixedly installed on the inner wall of the splint. The filter cloth is dynamically connected, and when backwashing the filter cloth, one end of the filter cloth can be clamped between the clamping plate and the expansion ring sleeve, and the filter cloth is spread flat on the outer surface of the expansion ring sleeve. Then the power component is triggered, and the two sets of linear motors respectively drive the two sets of annular clamping blocks to move toward each other to squeeze the ends of the filter cloth and fix the filter cloth on the outer surface of the expansion ring sleeve. Then, the rotary motor is started to drive the positioning shaft sleeve and the structure above it to rotate, while triggering the aeration component to generate flushing water containing a large number of bubbles to perform backwashing and cleaning operations on the filter cloth spread on the expansion ring sleeve.

[0007] Furthermore, the gap between the outer surface of the expansion ring and the arc-shaped surface on one side of the inner wall of the cleaning box is equal to the thickness of the filter cloth. Under the action of the expansion ring and the cleaning box, the flushing water containing a large number of bubbles generated by the aeration component can be concentrated and rotated to the filter cloth on the other side of the inner wall of the cleaning box, causing the filter cloth on the other side of the inner wall of the cleaning box to swell, thereby achieving a better backwashing cleaning effect on the filter cloth.

[0008] Furthermore, the end of the support ring is set as a conical inclined surface structure, and the inner end of the annular clamp is set as a concave inclined surface structure matching it, so as to effectively increase the friction and extrusion force generated by the annular clamp on the end of the filter cloth, thereby preventing the end of the filter cloth from loosening or falling off when backwashing the filter cloth.

[0009] Furthermore, a pressure plate is provided on one side of the bottom of the inner cavity of the cleaning box, and the inner wall of the pressure plate is set to an arc-shaped curved surface structure with the same trajectory as one side of the inner wall of the cleaning box, so that the bulging filter cloth can be squeezed by the pressure plate to further clean the solid particles stuck in the filter holes thereon, and the more stubborn solid particles attached to the outer surface of the filter cloth can be scraped off.

[0010] Furthermore, the pressure plate is elastically and movably connected to the cleaning box, and a linkage block is fixedly installed at one end of the pressure plate, and the linkage block is frictionally connected to the inner groove provided on the annular clamping block. Therefore, in the process of the annular clamping blocks moving toward each other, the pressure plate can be forced to move closer to the support ring under the transmission action of the linkage block, thereby regulating the extrusion force of the pressure plate on the bulging filter cloth.

[0011] The beneficial effects of the present invention are as follows:

[0012] The present application provides a composite filter cloth cleaning filter tank aeration backwashing equipment. Regarding the arrangement of the power component and the structure thereon, when the filter cloth is backwashed, the filter cloth can be spread flat on the outer surface of the open ring sleeve through the annular clamping block and the clamping plate and caused to rotate. Then, while the rotating filter cloth is backwashed and cleaned through the aeration component, the swollen filter cloth can be squeezed by the pressure plate to further clean the solid particles stuck in the filter holes thereon, and the more stubborn solid particles attached to the outer surface of the filter cloth can be scraped off, so that the backwashing cleaning effect of the filter cloth is better, and the stability and reliability are higher.
