Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a device for improving the filtration efficiency of a paper tape filter. Background Technology

[0002] In the pretreatment process of the SUV painting line, the paper tape filter is a key piece of equipment to ensure the cleanliness of the bath solution. Its core function is to trap iron filings in the bath solution through the paper tape, so as to prevent the iron filings from contaminating the pretreatment hot water wash, pre-degreasing and degreasing tanks.

[0003] However, existing paper belt filters have significant drawbacks: the tank liquid discharged from the water tank (especially the liquid discharged through the hydrocyclone separator) has extremely strong impact force, which can easily cause the paper belt to break upon direct impact. Once the paper belt breaks, the filtration function fails, and the contaminated tank liquid flows directly back into subsequent process tanks, damaging the process environment. Furthermore, frequent manual movement and replacement of damaged paper belts are required, increasing labor costs and significantly reducing the efficiency of iron filings removal, thus affecting the stability of the pretreatment process. Currently, there is no effective solution to this problem, and there is an urgent need for an improved device that can reduce the impact force of the tank liquid and prevent paper belt breakage, thereby improving the filtration reliability and iron filings removal capability of the paper belt filter. Utility Model Content

[0004] The purpose of this invention is to provide a device for improving the filtration efficiency of a paper tape filter, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for improving the filtration efficiency of a paper tape filter, adapted to a paper tape filter with a paper tape, including a water tank, the water tank being the liquid storage component of the paper tape filter, an L-shaped drain pipe installed at the bottom of the water tank, an opening at the bottom end of the drain pipe, through which the tank liquid in the water tank is sprayed horizontally outward from the opening, and a pressure relief plate installed at the opening of the drain pipe, the pressure relief plate being used to receive the tank liquid sprayed by the drain pipe and to relieve the pressure of the tank liquid, the paper tape being horizontally positioned downstream of the pressure relief plate in the direction of tank liquid outflow, and the upper surface of the paper tape being opposite to the lower edge of the pressure relief plate, for filtering the tank liquid that flows down naturally after being relieved by the pressure relief plate.

[0006] Preferably, an inlet is fixedly installed on the top of the water tank.

[0007] Preferably, a support frame is fixedly installed on the outer side of the pressure relief plate, and the paper tape is installed in the support frame.

[0008] Preferably, a plurality of support rods are fixedly connected between the support frame and the bottom of the water tank.

[0009] Preferably, the pressure relief plate includes a plate body and a frame, the frame is fixedly sleeved on the outside of the plate body, and the plate body has a plurality of through pressure relief holes.

[0010] Preferably, the plurality of pressure relief holes are distributed in a matrix array.

[0011] The technical effects and advantages of this utility model are as follows: 1. The L-shaped drain pipe guides the horizontal spray of the filtration solution, which is then caught by a pressure relief plate at the opening. The solution is dispersed and depressurized through the pressure relief holes on the plate, significantly reducing the impact force of the solution and completely solving the problem of paper tape being torn in existing technologies. This ensures continuous and effective filtration and prevents backflow of dirty solution. The pressure relief holes are arranged in a matrix array, allowing the solution to flow evenly to the horizontally positioned paper tape, avoiding uneven filtration caused by localized solution accumulation. This greatly improves the paper tape's efficiency in retaining iron filings and optimizes the iron filings removal effect.

[0012] 2. The support frame on the outside of the pressure relief plate can stably fix the paper tape, and the support frame is connected to the bottom of the water tank through the support rod to prevent paper tape displacement; there is no need for frequent manual adjustment and replacement of paper tape, reducing labor input, while ensuring the cleanliness of the pretreatment process tank solution and improving the overall process stability. The overall structure only requires the addition of drainage pipes, pressure relief plates and other components to the bottom of the water tank of the existing paper tape filter, without the need for large-scale modification of the original equipment, making it highly adaptable and low in implementation cost.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides, for example Figures 1-2The device shown is for improving the filtration efficiency of a paper tape filter, adapted to a paper tape filter with a paper tape. It includes a water tank 1, which is the liquid storage component of the paper tape filter. An L-shaped drain pipe 2 is installed at the bottom of the water tank 1. An opening 21 is opened at the bottom end of the drain pipe 2. The liquid in the tank 1 is sprayed outward from the opening 21 in a horizontal direction through the drain pipe 2. A pressure relief plate 3 is installed at the opening 21 of the drain pipe 2. The pressure relief plate 3 is used to receive the liquid sprayed from the drain pipe 2 and to relieve the pressure of the liquid. The paper tape is set horizontally downstream of the pressure relief plate 3 in the direction of liquid outflow, and the upper surface of the paper tape is opposite to the lower edge of the pressure relief plate 3. It is used to filter the liquid that flows down naturally after being relieved by the pressure relief plate 3.

[0017] The L-shaped drain pipe 2 guides the horizontal spray of the tank liquid, which is then received by the pressure relief plate 3 at the opening 21. The tank liquid is dispersed and relieved through the pressure relief holes 33 on the plate 31, which can significantly reduce the impact force of the tank liquid, completely solve the problem of paper tape being broken in the existing technology, ensure the continuous effectiveness of the filtration function, and prevent the backflow of dirty tank liquid.

[0018] Furthermore, an inlet 4 is fixedly installed on the top of the water tank 1.

[0019] Furthermore, a support frame 5 is fixedly installed on the outside of the pressure relief plate 3, and the paper tape is installed in the support frame 5.

[0020] Furthermore, multiple support rods 6 are fixedly connected between the support frame 5 and the bottom of the water tank 1.

[0021] Furthermore, the pressure relief plate 3 includes a plate body 31 and a frame 32. The frame 32 is fixedly sleeved on the outside of the plate body 31, and the plate body 31 has multiple through pressure relief holes 33.

[0022] Furthermore, the multiple pressure relief holes 33 are distributed in a matrix array.

[0023] The iron-containing blood residue solution generated by the pretreatment process flows into the water tank 1 through the liquid inlet 4 at the top of the water tank 1. The water tank 1 serves as a liquid storage component to temporarily store the solution to be filtered. After the solution in the water tank 1 is collected at the bottom, it is guided by the L-shaped drain pipe 2 installed at the bottom and sprayed outward from the opening 21 at the bottom of the drain pipe 2 in a horizontal direction. The sprayed liquid directly impacts the pressure relief plate 3 installed at the opening 21. The liquid is dispersed and flows through the matrix-type pressure relief holes 33 on the plate body 31 of the pressure relief plate 3, thereby achieving pressure relief, speed reduction, and elimination of high impact force. After the pressure is released, the tank liquid flows down naturally and flows to the horizontal paper tape located downstream of the tank liquid outflow direction of the pressure relief plate 3. The paper tape is installed in the support frame 5, and the support frame 5 is fixed to the bottom of the water tank 1 by the support rod 6 to ensure the stability of the paper tape position. The solution permeates and filters through the paper tape, trapping the iron filings. The filtered clean solution then enters the subsequent pretreatment process, completing one iron filings removal filtration cycle.

[0024] The L-shaped drain pipe 2 guides the horizontal spray of the filtration solution, which is then received by the pressure relief plate 3 at the opening 21. The filtration solution is dispersed and relieved through the pressure relief holes 33 on the plate 31, significantly reducing the impact force of the filtration solution and completely solving the problem of paper tape being torn in existing technologies. This ensures continuous and effective filtration and prevents backflow of dirty filtration solution. The pressure relief holes 33 are arranged in a matrix array, which allows the filtration solution to flow evenly to the horizontally arranged paper tape, avoiding uneven filtration caused by local filtration solution accumulation. This greatly improves the paper tape's efficiency in retaining iron filings and optimizes the iron filings removal effect.

[0025] The support frame 5 on the outside of the pressure relief plate 3 can stably fix the paper tape, and the support frame 5 is connected to the bottom of the water tank 1 through the support rod 6 to prevent paper tape displacement. This eliminates the need for frequent manual adjustments and replacements of the paper tape, reducing labor input, while ensuring the cleanliness of the pretreatment process solution and improving overall process stability. The overall structure only requires the addition of components such as the drain pipe 2 and pressure relief plate 3 to the bottom of the water tank 1 of the existing paper tape filter, without requiring large-scale modifications to the original equipment. It is highly adaptable and has low implementation costs.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
