Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a quick-release pressurized filter used for epoxy resin. Background Art

[0002] The filter is a device used to filter tiny impurities and particles. The commercially available filters use round or hexagonal nuts as the head. When cleaning or replacing the filter, it is necessary to use a round-headed special caliper tool or a larger and longer wrench to disassemble it. However, when the filter is in a small space, the use of special disassembly tools or large wrenches will be limited by the space, resulting in low work efficiency and inconvenience. Especially during filtering work, when there are many impurities, the filter needs to be replaced frequently or the filter needs to be cleaned, which greatly reduces the work efficiency.

[0003] In order to increase the filtering speed, pressurized filtration is usually used. Only the filter in the filter is used for filtering. When there are many impurities and the filter is not replaced in time, the resistance in the filter will become larger and larger, and the filter will be squeezed and broken, which greatly reduces the filtering efficiency. The requirements for the filter are high, resulting in high replacement costs. In order to solve this problem, we proposed a quick-release pressurized filter for epoxy resin production. Utility Model Content

[0004] In view of the above problems, the present invention provides a quick-release pressurized filter for epoxy resin, which not only solves the problem of difficulty in replacing or cleaning the filter and the easy breakage of the filter during pressurized filtration after the epoxy resin production is completed, but also simplifies the replacement process, reduces labor intensity, and improves the filtration efficiency of the epoxy resin.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is as follows:

[0006] A quick-release pressurized filter for epoxy resin, comprising a feed port, a filter housing and a discharge port, wherein an inner liner tube is arranged in the filter housing, filter holes are evenly arranged on the tube wall of the inner liner tube, a filter screen is arranged on the outer sleeve of the inner liner tube, the inner diameter of the discharge port is smaller than the inner diameter of the inner liner tube, one end of the inner liner tube is in contact with the discharge port, and the other end of the inner liner tube is sealed with a spiral cover plate to fix the filter screen, and at least three steel bars are arranged in the radial direction of the spiral cover plate.

[0007] Preferably, the feed port is arranged on a side of the filter housing, and the discharge port is arranged at one end of the filter housing.

[0008] Preferably, the other end of the filter housing is threadedly connected to the spiral cover plate, a socket is provided at the center of the spiral cover plate, and the socket is nested and connected to the liner pipe.

[0009] Preferably, a handle is provided on the spiral cover plate.

[0010] Preferably, the inner diameter of the filter housing is larger than the outer diameter of the liner tube.

[0011] Preferably, the pore size of the filter is 15-18 mesh.

[0012] Preferably, the discharge port is funnel-shaped.

[0013] Preferably, the filter housing is integrally injection molded.

[0014] Preferably, the handle is cylindrical in shape.

[0015] Preferably, the pore size of the filter holes is 1-3 mm, the interval between adjacent filter holes is 2-4 mm, and the shape of the filter holes is circular.

[0016] The utility model has the following positive effects:

[0017] 1. The utility model provides at least three steel rods, an inner liner tube and a filter screen covered by the inner liner tube in the radial direction of the spiral cover plate. When the filter screen needs to be cleaned or replaced, the steel rods welded at the spiral cover plate are directly used to remove it by hand, and then the filter screen is cleaned or replaced. This not only solves the problem that it is difficult to replace or clean the filter screen and the filter screen is easy to break during pressurized filtration after the production of epoxy resin is completed, but also simplifies the replacement process, reduces labor intensity, and improves the filtration efficiency of epoxy resin.

[0018] 2. The inner liner tube of the utility model is provided with filter holes, the aperture of which can be adjusted according to actual needs, which can not only adapt to different epoxy resin filtering conditions, but also the filter holes interact with the filter screen during the pressurized filtration process, thereby improving the filtering quality of the epoxy resin.
