Embodiment Construction

[0025] Based on the working principle of the water turbine, the present invention converts water energy into mechanical energy, and uses the energy of the liquid itself to drive the rotary cleaning device to perform 360° cycle rotation by rationally arranging the impeller, liquid outlet diameter and outlet inclination, and to clean the filter screen continuously. Make the filter residue gather in the conical slag collection chamber, and remove the filter residue through the slag discharge port.

[0026] The brush-type hydraulically driven self-cleaning filter includes a filter housing 1, a liquid inlet 3 and a liquid outlet 4 installed on both sides of the filter housing, a filter cleaning device and a filter 5 arranged in front of the liquid outlet 4, and the filter The cleaning device includes an impeller and cleaning parts. The impeller includes a special-shaped wheel body and blades 6 installed on the wheel body. The number of blades can be set according to needs. The water...

Abstract

The invention relates to a self-cleaning filter which is capable of using the energy of liquid and is suitable for transmission pipelines of refined oil. A special-shaped swiveling wheel is arranged in the filter, and is provided with nylon brushes; a liquid inlet is arranged tangentially, and an optimized angle is formed between the liquid inlet and a liquid outlet. According to the operation principles of a water turbine, when the filter runs, the liquid enters into the filter and rotates in the filter to push the special-shaped swiveling wheel to rotate; and one nylon brush arranged on one blade of the swiveling wheel will be used for clearing impurities captured by a filter screen, so that the filter screen is prevented from being blocked. A top cover and a cylinder body of the filter are connected by a clamping hoop fastening structure, can be disassembled by dismounting 4 to 6 bolts, and are easy and convenient to be disassembled. The self-cleaning filter which is capable of using the energy of liquid for automatic cleaning of the filter screen disclosed in the invention helps to solve problems that: existing self-cleaning filter needs an extra drive unit and an extra control unit, and is only suitable for low pressure working conditions; liquid backwashing is required; and deslagging is uncomplete.

Description

technical field [0001] The invention relates to a brush-type hydraulically driven self-cleaning filter, in particular to a self-cleaning filter suitable for fireproof and explosion-proof, large-flow fluid delivery pipelines. Background technique [0002] The existing self-cleaning filter has the following characteristics: the driving device is driven by motor or hydraulic pressure, the control part feeds back the pressure difference signal, the driving device starts to run, and the cleaning device (suction type, brush type and backwash type) cleans the filter medium. Remove impurities. However, the existing self-cleaning filter has a complex structure and low reliability, which increases the maintenance workload and takes a long time, increases the operating cost of the filter, and may even affect the normal operation of the entire system equipment, and does not have Explosion-proof function; the cleaning part (cleaning brush) is made of rigid material, which is consistent ...
