Description

Technical Field

[0001] This utility model belongs to the technical field of metal corrugated filter cartridges, specifically relating to a pipeline-type metal corrugated filter cartridge precision filter. Background Technology

[0002] A pipeline metal corrugated filter is a filtration device used in pipeline systems. When fluid (liquid or gas) enters the filter through the pipeline, impurity particles in the fluid are intercepted by the metal corrugated filter element.

[0003] Due to the corrugated structure of the filter element, impurities will gradually accumulate on the surface or inside of the filter element, while the filtered clean fluid continues to flow in the pipeline. As the filtration process continues, the impurities accumulated on the filter element will gradually increase. When they reach a certain level, they may affect the filtration effect and the flow rate of the fluid. At this time, the filter element needs to be cleaned or replaced.

[0004] However, during the replacement of the filter element, the staff needs to loosen the bolts to remove the cover plate in order to take out the filter element. After the filter element is replaced, the bolts need to be loosened again to fix the cover plate in order to complete the replacement of the filter element. Therefore, this greatly reduces the work efficiency of the staff. Utility Model Content

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-5 This utility model provides a pipeline-type metal pleated filter element precision filter, including a filter box 1. The bottom of the filter box 1 is provided with a placement groove 2. A metal pleated filter element 3 is movably installed inside the placement groove 2. The top of the filter box 1 is provided with a fixing structure for the metal pleated filter element 3. The fixing structure includes an auxiliary groove 31 opened on the top of the filter box 1. A sealing cover 32 is rotatably connected to the middle of the auxiliary groove 31. A support plate 33 is fixedly connected to the top of the sealing cover 32 in a left-right symmetrical manner. A connecting shaft 34 is fixedly connected to the opposite side of the support plate 33. A support platform 35 is fixedly connected to the back of the filter box 1. A lifting rod 36 is fixedly connected to the inside of the support platform 35 in a left-right symmetrical manner.

[0024] The telescopic end of the lifting rod 36 is rotatably connected to the connecting shaft 34. By activating the lifting rod 36, the telescopic end of the lifting rod 36 provides upward support to the connecting shaft 34, thereby causing the sealing cover 32 to rotate inside the auxiliary groove 31 and complete the closing of the sealing cover 32. During the closing process, the fixing plate 6 of the sealing cover 32 will contact the top of the metal pleated filter element 3, thereby fixing the position of the metal pleated filter element 3.

[0025] Specifically, such as Figure 3 As shown, the left side of the filter box 1 is fixedly connected to the water inlet pipe 4, the bottom of the filter box 1 is fixedly connected to the water outlet pipe 5, and the bottom of the sealing cover 32 is fixedly connected to the fixing plate 6.

[0026] Specifically, such as Figure 3, Figure 4 and Figure 5 As shown, the inner wall of the placement groove 2 is provided with a circular array of fixing grooves 9, and a connecting structure is installed on the side surface of the bottom of the metal pleated filter element 3. The connecting structure includes fixing blocks 91 that are fixedly connected to the bottom side surface of the metal pleated filter element 3 in a circular array.

[0027] The fixed block 91 has a movable groove 92 inside. The side surface inside the movable groove 92 has symmetrical limit grooves 93. The movable groove 92 is slidably connected to the second support platform 94. The top of the second support platform 94 is fixedly connected to a helical spring 95. The other end of the helical spring 95 is fixedly connected to the top inside the movable groove 92.

[0028] The fixing groove 9 is L-shaped, and the fixing block 91 is adapted to the fixing groove 9. The fixing block 91 at the bottom of the metal corrugated filter element 3 is inserted into the fixing groove 9 and rotated so that the fixing block 91 is inserted deep into the fixing groove 9. Then, the elastic force of the helical spring 95 drives the support platform 2 94 to support the metal corrugated filter element 3, thereby improving the stability and safety of the installation of the metal corrugated filter element 3.

[0029] Specifically, such as Figure 3 As shown, a sealing gasket 7 is fixedly connected to the bottom of the sealing cover 32 and to the outside of the fixing plate 6, and a water pressure sensor 8 is fixedly connected to the bottom inside the filter box 1.

[0030] The water pressure sensor 8 can detect the water pressure inside the filter housing 1. When the metal pleated filter element 3 is severely clogged and cannot filter water normally, the water pressure inside the filter housing 1 will increase; otherwise, it is normal.

[0031] Specifically, such as Figure 1 As shown, a display screen 10 is fixedly connected to the front of the filter housing 1, and a heat dissipation groove 11 is provided on the right side of the filter housing 1. A strip grid 12 is fixedly connected inside the heat dissipation groove 11.

[0032] The working principle and usage process of this utility model: During use, the staff first fixes the filter box 1 in a suitable position and connects the inlet pipe 4 and the outlet pipe 5 to the external water pipe respectively.

[0033] Then the metal corrugated filter element 3 can be fixedly placed inside the placement groove 2. During the placement process, the fixing block 91 at the bottom of the metal corrugated filter element 3 needs to be inserted into the fixing groove 9 and rotated so that the fixing block 91 is inserted deep into the fixing groove 9. Then, the elastic force of the helical spring 95 drives the support platform 2 94 to support the metal corrugated filter element 3, thereby improving the stability and safety of the installation of the metal corrugated filter element 3.

[0034] Finally, by activating the lifting rod 36, the telescopic end of the lifting rod 36 rises and supports the connecting shaft 34, causing the sealing cover 32 to rotate inside the auxiliary groove 31 and close. During the closing process, the fixing plate 6 of the sealing cover 32 contacts the top of the metal pleated filter element 3, thereby fixing the position of the metal pleated filter element 3. When the metal pleated filter element 3 needs to be replaced or cleaned after long-term use, the telescopic end of the lifting rod 36 can be retracted by activating the lifting rod 36, which will drive the sealing cover 32 to rotate and open, making it convenient to remove and clean the metal pleated filter element 3. This effectively improves the convenience of removing the metal pleated filter element 3 and facilitates its use by staff.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
