Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a parallel filter element. Background Art

[0002] The filter is an indispensable device on the pipeline for conveying medium, and is usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level valve, and other equipment of Fanggong filter. The filter has a filter cartridge with a certain specification of filter screen, and its impurities are blocked. When it needs to be cleaned, just take out the detachable filter cartridge, process it and reinstall it, so it is very convenient to use and maintain.

[0003] The existing public technology has a publication number of CN207871650U, which is a new type of filter equipment. It includes a main PPR cylinder, a liquid inlet pipe, a pump, a filter element and a liquid outlet pipe. Several filter elements are evenly distributed in the main PPR cylinder. The bottom of the main PPR cylinder is connected to the liquid inlet pipe, and a pump is arranged on the liquid inlet pipe. The bottom side wall of the main PPR cylinder is connected to the liquid outlet pipe. Several filter elements are connected in parallel with each other, and several filter elements are squeezed from the inside to the outside. Several filter elements are respectively mounted on their own hole filter element seats, and several filter elements are respectively pressure-tested by pressure gauges. The diameter of the main PPR cylinder is 50mm; the pump adopts a self-priming pump. The utility model eliminates the hidden danger of filter element clogging, meets the requirements for solution circulation, and makes the solution reach a pure state.

[0004] Combining the above patents with actual production and life, it is not difficult to find that the filter element in the filter is more complicated to install, and its top thread needs to be rotated so that the filter element can be used stably. It also needs to be rotated during subsequent disassembly, which is time-consuming and labor-intensive. In addition, since the filter elements are arranged in parallel, there is no separation measure when the liquid flows. This results in the need to shut down the entire structure when a specific filter element needs to be replaced. Otherwise, the flow of liquid will affect the replacement operation, reducing the overall maintenance efficiency, and causing greater interference to the operation of the device, resulting in the use effect being not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Then, when it needs to be disassembled later, it is only necessary to pull the insertion rod 16 to make it When the filter element 9 is replaced, the adjusting shaft 8 at the designated position can be rotated, and the adjusting shaft 8 can drive the sealing cover 4 to be inserted into the sealing groove 7. At this time, the inlet and outlet liquid gaps at both ends of the filter element 9 can form a sealing area with the liquid to prevent the outflow of liquid. At this time, the personnel can replace the designated filter element 9 without stopping the overall liquid flow, which effectively reduces the interference of maintenance on the use of the intact filter element 9 and improves the overall use effect. The device as a whole has the advantages of convenient loading and unloading, independent replacement, and small impact of replacement.
