[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Example:

[0021] The accompanying drawings illustrate a specific embodiment of the leak-proof paper tape filter of this utility model. Figure 1 The filter mainly includes a filter box 1, inside which is a supporting filter screen 2, and a V-shaped paper strip 3 is mounted on the supporting filter screen 2. One end of the V-shaped paper strip 3 is connected to an unwinding roller 12, and the other end is connected to a recovery mechanism 13. The recovery mechanism 13 includes a take-up roller driven by a paper feeding motor. The filter adopts a dual-roller structure (unwinding roller + take-up roller), driven by a paper feeding motor, to achieve automatic paper strip feeding without the need for manual paper strip replacement.

[0022] The filter box 1 is equipped with an inlet 1a and an outlet 1b, which are located on the upper and lower sides of the V-shaped paper belt 3, respectively. A filtrate tank 11 is located below the filter box 1, and the outlet 1b is connected to the filtrate tank 11. The raw liquid containing impurities enters the filter box 1 through the inlet 1a, is filtered by the V-shaped paper belt 3 (supported by a support filter screen 2), and the filtrate enters the filtrate tank 11 through the outlet 1b.

[0023] In this embodiment, combined with Figure 3 The V-shaped paper tape 3 comprises, from top to bottom, a non-woven fabric layer 3a, a filter paper layer 3b, and a tear-resistant layer 3c. The surface layer of the V-shaped paper tape 3 is made of highly permeable non-woven fabric for pre-filtering large particles; the middle layer is filter paper for intercepting fine particles; and the bottom layer, the tear-resistant layer 3c, is woven from transverse and longitudinal tensile fibers to enhance mechanical strength and prevent tearing. This multi-layered filtration structure extends the lifespan of the paper tape, reduces consumable costs, and improves filtration accuracy.

[0024] Slots 4 are provided on the inner walls of both sides of the filter box 1, and the two edges of the V-shaped paper tape 3 are respectively placed in the slots 4 on both sides. Figure 2The bottom of the slot 4 is provided with a connected T-shaped groove 4a, which extends along the length of the slot 4. A spring 6 is provided at the bottom of the T-shaped groove 4a. Several springs 6 can be provided and closely distributed along the T-shaped groove 4a. The upper ends of several springs 6 are connected to elastic sealing strips 5. The elastic sealing strips 5 are provided in the upper part of the T-shaped groove 4a and can move up and down. The elastic sealing strips 5 extend along the length of the T-shaped groove 4a and are T-shaped, so they will not come out of the T-shaped groove 4a. The top of the elastic sealing strip 5 is provided with an upwardly protruding main sealing lip 14 and a secondary sealing lip 15. The main sealing lip 14 and the secondary sealing lip 15 extend along the length of the elastic sealing strip 5. The secondary sealing lip 15 is located near the edge of the V-shaped paper tape 3, and the main sealing lip 14 is located inside the secondary sealing lip 15. The main sealing lip 14 and the secondary sealing lip 15 are used to achieve a tight fit with the V-shaped paper tape 3 and facilitate the replacement of the V-shaped paper tape 3. A pressure sensor 7 is provided below the elastic sealing strip 5, and the pressure sensor 7 is embedded in the T-slot 4a.

[0025] The top of slot 4 has a communicating upper groove 4b, which extends along the length of slot 4. A pressure plate 8 is movable up and down within the upper groove 4b, also extending along the length of the groove. The pressure plate 8 is made of aluminum alloy, making it lightweight. A buffer pad 9, made of polyurethane, is located at the bottom of the pressure plate 8 to prevent direct rigid contact and damage to the paper tape. A cylinder 10 is located at the top of filter box 1. The output shaft of the cylinder 10 is connected to the top of the pressure plate 8. In this embodiment, a cylinder 10 is connected to each end of the pressure plate 8 to ensure uniform pressure. A guide rod 16 is also connected to the top of the pressure plate 8. A linear bearing 17 is located inside the filter box 1, and the guide rod 16 is installed within the linear bearing 17 to ensure vertical movement of the pressure plate 8 during the pressing process. The pressure plate 8 can cooperate with the elastic sealing strip 5 to press and seal the edge of the V-shaped paper tape 3, effectively preventing liquid leakage from the edge of the paper tape and ensuring the stability of the filtration efficiency.

[0026] In the specific operation of this embodiment, as follows: Figure 2 As shown, first, the edge of the V-shaped paper tape 3 is installed along the slot 4. At this time, the elastic sealing strip 5 and the buffer pad 9 at the bottom of the pressure plate 8 are not in contact with the V-shaped paper tape 3, and the pressure sensor 7 cannot detect a pressure signal. Then, the cylinder 10 drives the pressure plate 8 to press down, and the pressure plate 8 drives the buffer pad 9 to press down, as shown. Figure 4As shown, the buffer pad 9 contacts the V-shaped paper tape 3 and continues to press down for a certain distance before stopping, making the V-shaped paper tape 3 in close contact with the elastic sealing strip 5. Under the action of the spring 6, the main sealing lip 14 and the secondary sealing lip 15 at the top of the elastic sealing strip 5 are tightly fitted with the V-shaped paper tape 3. At this time, the pressure sensor 7 cannot detect a pressure signal. In this state, the buffer pad 9 and the elastic sealing strip 5 are used to slightly press the edge of the V-shaped paper tape 3 for sealing during paper tape replacement, preventing liquid leakage from the edge. After the paper tape replacement is completed, the cylinder 10 continues to drive the pressure plate 8 to press down, and the pressure plate 8 continues to drive the buffer pad 9 to press down, as... Figure 5 As shown, the buffer pad 9 presses the V-shaped paper tape 3 down to the bottom of the slot 4, and the elastic sealing strip 5 further fits tightly with the V-shaped paper tape 3. At this time, the main sealing lip 14 and the secondary sealing lip 15 undergo elastic deformation and fit more tightly. The pressure sensor 7 detects the pressure signal, indicating that the V-shaped paper tape 3 has been compressed and a highly reliable seal has been achieved. At this time, filtration can be carried out, and the liquid will not leak from the edge of the paper tape.

They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
