Description

Technical Field

[0001] The utility model relates to the technical field of pipeline filters, in particular to a pipeline filter with an automatic cleaning function. Background Art

[0002] Pipeline filter, a hydraulic term, is a filter used for the pipeline part of the hydraulic system. Pipeline filter is a filter involved in the pipeline transportation process. It is installed on the pipeline to remove larger solid impurities in the fluid, so that machinery, equipment and instruments can work and operate normally, achieve a stable process and ensure safe production. After long-term use, the filter basket used for filtration will contain a large amount of impurities.

[0003] Patent application number 202321126913.9 discloses a pipe filter with an automatic cleaning device, including a pipe filter body and an electric push rod, the inner wall of the pipe filter body is provided with a fixed tube, the inner wall of the fixed tube is slidably mounted with a filter basket, the output end of the electric push rod is fixedly mounted with a movable circular plate, and the surface of the movable circular plate is fixedly mounted with a sealing ring. The movable circular plate is driven by the electric push rod to move to the outside of the pipe filter body, and the water pump draws out the water inside the pipe filter body through the pumping pipe, and the water is output through the output pipe, and sprayed to the surface of the movable circular plate through the nozzle to rinse the impurities on the surface of the movable circular plate. After rinsing, the electric push rod drives the movable circular plate to move to the inner wall of the filter basket to block the bottom of the filter basket.

[0004] However, this technical solution requires that the filter structure be supported by an electric push rod at all times. When the electric push rod is powered off, the filter structure is prone to slipping, resulting in poor sealing effect of the pipeline filter. At the same time, in order to be able to move the filter structure out of the pipeline, the inclined filter structure causes the flow space inside the filter to be reduced, thereby reducing the flow rate of water. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and provide a pipeline filter with an automatic cleaning function, which realizes the cleaning function on both sides of the filter plate through a flushing pipe and a driving pipe structure in conjunction with a flushing frame and a blade structure, thereby solving the problem that the filter structure cannot be installed normally and has a poor sealing effect due to being removed from the pipeline for cleaning.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipe filter with automatic cleaning function, comprising a pipe body and control valves installed at both ends of the pipe body, a filter plate is embedded and fixed in the pipe body, and a flushing frame located on the side wall of the filter plate is fixed on the pipe body, an installation shaft is rotatably provided at one end of the filter plate away from the flushing frame, blades and a scrubbing plate are respectively fixed at both ends of the installation shaft, a delivery pipe is fixed at the bottom end of the pipe body, a drive pipe and a flushing pipe are respectively installed on the delivery pipe, the flushing pipe and the drive pipe are respectively connected to the outer wall of the pipe body and the flushing frame, and the drive pipe is staggered with the axis of the pipe body.

[0007] Preferably, a sewage pipe is installed at the bottom end of the pipeline body, and solenoid valves are installed on the sewage pipe, the flushing pipe and the driving pipe.

[0008] Furthermore, a tee is fixedly installed on the connecting pipe, and the tee is fixedly connected to the flushing pipe and the driving pipe respectively.

[0009] Furthermore, the inner wall of the flushing rack is provided with flushing holes in a circular array, and the plurality of flushing holes are all facing the side wall of the filter plate.

[0010] Furthermore, a support rod is embedded and fixed at the center of the filter plate, and a filter element is embedded in the filter plate, and the installation shaft is rotatably inserted in the support rod.

[0011] Furthermore, the blades are arranged in a plurality in an annular array, and one end of the driving pipe extending into the pipe body corresponds to the blades.

[0012] Furthermore, rotating plates are fixed on both sides of the outer wall of the mounting shaft, one end of the scrubbing plate is fixedly connected to the rotating plate, and the other end of the scrubbing plate is in contact with the filter plate.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model provides control valves at both ends of the pipeline body and installs a delivery pipe on the pipeline body. When the filter plate is self-cleaned, the control valves at both ends of the pipeline body are closed and multiple solenoid valves are opened. Water in the pipeline body is discharged along the flushing pipe and the driving pipe through the delivery pipe. The flushing pipe flushes the surface of the filter plate through multiple flushing holes on the inner wall of the flushing frame. The water flow in the driving pipe contacts the blades and causes the blades to drive the mounting shaft to rotate. When the mounting shaft rotates, it drives the rotating plate and the scrubbing plate to move, so that the scrubbing plate scrubs the surface of the filter plate. The water flow splashed by the contact between the water flow and the blade surface flushes the scrubbed filter plate, which is convenient for self-cleaning of the filter plate fixed in the pipeline and improves the cleaning effect of the filter plate.
