[0008] As a further solution of the utility model, the mesh core is pressed between the first fixing ring and the second fixing ring in multiple stages by the first groove, the second groove and the convex ring.

[0009] As a further solution of the utility model, a mounting structure is provided on the upper part of the first fixing ring, and the mounting structure includes a mounting seat and an externally threaded tube. The externally threaded tube is fixedly installed on the top of the first fixing ring, and the mounting seat is threadedly connected to the outside of the externally threaded tube. A plurality of mounting holes are opened at the edge of the upper surface of the mounting seat.

[0010] As a further solution of the utility model, a boss is fixedly mounted on the inner wall of the mounting seat, and a sealing groove is opened on the lower surface of the boss, and a rubber ring is placed inside the sealing groove.

[0011] As a further solution of the utility model, the height of the external threaded tube is the same as the distance between the bottom surface of the boss and the bottom surface of the mounting seat.

[0012] As a further solution of the utility model, external hexagonal blocks are fixedly installed on the outside of the first fixing ring and the second fixing ring.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting the first fixing ring and the second fixing ring, the entire filter structure is connected in an assembled manner, which facilitates the replacement of the filter core in the later stage and improves the convenience of maintenance and operation;

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 5 As shown, an assembled filter screen for raw liquid treatment includes a first fixing ring 1 and a second fixing ring 2, a mesh core 3 is provided between the first fixing ring 1 and the second fixing ring 2, and a convex ring 7 is integrally connected to the bottom of the first fixing ring 1 near the inner side, and a first groove 8 is provided on the bottom surface of the first fixing ring 1 located on the outer side of the convex ring 7, a second groove 9 is provided on the top surface of the second fixing ring 2, and the convex ring 7 is adaptively matched with the second groove 9, the first groove 8 is adaptively matched with the outer contour of the second fixing ring 2, and the inner wall of the first groove 8 is threadedly connected with the outer wall of the second fixing ring 2.

[0025] In this embodiment, the mesh core 3 is pressed between the first fixing ring 1 and the second fixing ring 2 in multiple stages by the first groove 8, the second groove 9 and the convex ring 7;

[0026] The mesh core 3 is compressed so that it is detachable and easy to replace in later use.

[0027] In this embodiment, a mounting structure is provided on the upper part of the first fixing ring 1, and the mounting structure includes a mounting seat 4 and an externally threaded tube 5. The externally threaded tube 5 is fixedly mounted on the top of the first fixing ring 1, and the mounting seat 4 is threadedly connected to the outside of the externally threaded tube 5. A plurality of mounting holes are provided at the edge of the upper surface of the mounting seat 4.

[0028] The installation structure facilitates the connection of the entire filter structure to external equipment, and during later disassembly, there is no need to frequently use bolts to connect external equipment.

[0029] In this embodiment, a boss 6 is fixedly mounted on the inner wall of the mounting seat 4, and a sealing groove 10 is formed on the lower surface of the boss 6, and a rubber ring 11 is placed inside the sealing groove 10;

[0030] The boss 6 cooperates with the rubber ring 11 to enhance the sealing performance, thereby improving the sealing performance between the external threaded tube 5 and the mounting seat 4 .

[0031] In this embodiment, the height of the external threaded tube 5 is the same as the distance between the bottom surface of the boss 6 and the bottom surface of the mounting seat 4;

[0032] When the externally threaded tube 5 is completely screwed into the mounting seat 4 , the externally threaded tube 5 can squeeze the rubber ring 11 , compressing and deforming the rubber ring 11 , thereby achieving the effect of increasing the sealing performance.

[0033] In this embodiment, the first fixing ring 1 and the second fixing ring 2 are both fixedly mounted with external hexagonal blocks;

[0034] The outer hexagonal block can facilitate the force application operation to rotate the first fixing ring 1 and the second fixing ring 2.

[0035] It should be noted that the utility model is an assembled filter screen for raw liquid treatment. When in use, an external bolt is used to penetrate the mounting hole on the top surface of the mounting seat 4 to fix it at the discharge port position of the raw liquid processing equipment or on the raw liquid pipeline. When the raw liquid passes through, it can be filtered by the mesh core 3 and then discharged from the second fixing ring 2, thereby purifying the raw liquid. The inner wall of the second fixing ring 2 is provided with a thread, which can be used to connect a corresponding pipeline to receive the discharged raw liquid;

[0036] In later maintenance, the first fixing ring 1 can be rotated first, and the first fixing ring 1 drives the external threaded tube 5 to rotate, and the external threaded tube 5 is separated from the mounting seat 4, so that the entire filter structure can be removed, which is convenient for maintenance and replacement;

[0037] After removing the first fixing ring 1, the first fixing ring 1 and the second fixing ring 2 can be rotated in opposite directions to separate the first fixing ring 1 and the second fixing ring 2, and the mesh core 3 can be removed, and a new mesh core 3 can be placed between the first fixing ring 1 and the second fixing ring 2, and then the first fixing ring 1 and the second fixing ring 2 are pressed and rotated. After the first fixing ring 1 and the second fixing ring 2 are fully engaged, the convex ring 7 is inserted into the second groove 9, and the first groove 8 is sleeved on the outside of the second fixing ring 2, so that the mesh core 3 is pressed between the first fixing ring 1 and the second fixing ring 2 in multiple sections, and finally the external threaded tube 5 can be connected to the mounting seat 4 again. The overall assembly connection method is adopted, which is convenient for later maintenance.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
