Description

Technical Field

[0001] This utility model relates to the field of pipeline filter technology, and in particular to a pipeline sealed Y-type filter device. Background Technology

[0002] In steel production processes, such as steelmaking and rolling, Y-type filters are used in the continuous casting turbidity circulating water system to filter particulate impurities within the pipeline, stabilizing water quality and reducing nozzle clogging rates. Most steel companies use socket-type filter screens secured with bolts. During use, the filter screen deforms under pressure, leading to a poor seal between the screen and the filter housing. Particulate matter flows through these gaps to the end, affecting filtration efficiency and clogging nozzles, further impacting billet cooling and product quality. Furthermore, cleaning Y-type filters requires offline disassembly and cleaning, reducing work efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a pipeline-sealed Y-type filter device. By adding annular concave grooves at both ends of the cylindrical double-layer filter screen and setting valve body concave grooves on the Y-type filter valve body, the sealing effect of the connection is improved, replacing the original filter screen socket connection method, which can effectively prevent filter screen deformation and particulate matter leakage.

[0004] To achieve the above objectives, this utility model provides a pipeline-sealed Y-type filter device, comprising:

[0005] Y-type filter valve body, which has a filter cavity, the bottom of which is biased towards the water inlet direction;

[0006] Valve cover, connected to the top of the Y-type filter valve body;

[0007] A cylindrical double-layer filter screen is installed inside the filter cavity, and annular concave grooves are installed at both ends to increase the sealing between the cylindrical double-layer filter screen and the Y-type filter valve body;

[0008] A drain valve is located at the center of the valve cover, and the drain valve is configured to control the discharge of sewage from the inner cavity of the cylindrical double-layer filter screen.

[0009] Furthermore, the pipeline-sealed Y-type filter device also includes: a positioning ring disposed on the outside of the cylindrical double-layer filter screen, the positioning ring being sleeved on the upper end of the cylindrical double-layer filter screen to prevent the cylindrical double-layer filter screen from shaking in the filter cavity, and the positioning ring being configured to fix the cylindrical double-layer filter screen.

[0010] Furthermore, the length of the cylindrical double-layer filter screen is less than the filter cavity of the Y-type filter valve body to avoid deformation of the cylindrical double-layer filter screen under pressure.

[0011] Furthermore, the pipeline-sealed Y-type filter device also includes an O-ring seal, which is disposed in the annular concave groove to further improve the sealing performance between the cylindrical double-layer filter screen and the Y-type filter valve body.

[0012] Furthermore, the cylindrical double-layer filter screen includes an outer skeleton and an inner filter screen with a specific mesh size, wherein the inner filter screen can be selected with a corresponding mesh size according to different filtration requirements.

[0013] Furthermore, the valve cover is tightly connected to the Y-type filter valve body by bolts and nuts to improve the sealing of the filter cavity.

[0014] Furthermore, the Y-type filter valve body is provided with a valve body concave groove, which is configured to cooperate with the annular concave groove at the bottom of the cylindrical double-layer filter to fix the cylindrical double-layer filter.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] (1) This utility model changes the traditional method of adding annular concave grooves at both ends of the cylindrical double-layer filter screen and setting valve body concave grooves on the Y-type filter valve body. This realizes a soft connection between the filter screen and the Y-type filter valve body, replacing the filter screen socket connection method. This improves the sealing of the connection part and effectively prevents leakage caused by filter screen deformation due to pressure. It also ensures that particulate impurities are effectively intercepted and prevents them from flowing into the end of the system through gaps, thereby ensuring a better filtration effect.

[0017] (2) In this utility model, a drain valve is configured on the Y-type filter valve body, which can be opened directly for cleaning without interrupting the production process. The existing water pressure in the pipeline is used to flush the inner cavity of the filter screen, quickly discharge the accumulated particulate matter, simplify the maintenance process, reduce the time and labor costs required for offline disassembly and cleaning, and improve work efficiency.

[0018] (3) The cylindrical double-layer filter screen is fixed by using a positioning ring in conjunction with the concave groove of the valve body, making the entire filter assembly more stable and reliable. At the same time, the filter screen skeleton and the mesh size of the inner filter screen are adjusted according to different filtration needs, and the filter screen height is designed to be slightly smaller than the inner cavity of the filter, which further optimizes the filtration performance and extends the service life.
