Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device. Background Technology

[0002] Existing technology discloses a filtration device for producing solvent-free polyurethane adhesives (application number: CN202420946466.X). To address the issue that while general adhesives have low viscosity and can be filtered by their own weight through a filter screen or cloth, some solvent-free polyurethane adhesives have a certain viscosity and, due to factors such as storage environment or specific formulations, can form viscous clumps internally. In such cases, filtration by their own weight through the filter screen is ineffective and time-consuming, affecting actual processing efficiency and the quality of the finished adhesive product. The device addresses this by feeding adhesive into a buffer chamber through an injection pipe. When the adhesive in the buffer chamber... Once the adhesive is filled, it passes through the coarse filter holes under pressure and enters the fine filter chamber inside the filter compartment. Simultaneously, driven by an external motor, the central rod rotates, causing the scraper to rotate inside the fine filter chamber. As the scraper rotates, it can concentrate the impurities generated on the inner wall of the fine filter chamber during filtration, preventing the fine filter chamber from clogging. During this process, the viscous clumps are broken up by the coarse filter holes. If the broken clumps meet the filtration conditions, they will filter normally. However, in the above technical solution, the fine filter chamber has a circular opening for discharge. Due to gravity, the adhesive squeezed out from the upper surface will accumulate and cannot fall normally, easily increasing the risk of clogging. Therefore, this application provides a filtration device to meet the requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a filtration device to solve the problem that in the existing fine filter barrel with surrounding openings for material discharge, the adhesive squeezed out from the upper surface due to gravity will accumulate and cannot fall normally, which will easily increase the risk of blockage.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A filtration device includes a filter frame, a feed pipe on the upper surface of the filter frame, and a cover rotatably mounted on the side wall of the filter frame. A drive motor is mounted on the side wall of the filter frame, and the drive motor is distributed opposite to the cover. A discharge pipe is installed at the bottom of the filter frame. The filter frame has a filter chamber inside, and a movable and detachable filter screen is provided inside the filter chamber. The filter screen has a semi-circular ring structure, and a stirring blade is provided at the center of the filter screen inside the filter chamber.

[0005] Preferably, multiple sets of stirring blades are arranged around the center, and a rotating shaft is fixedly connected to the center. The rotating shaft is horizontally rotatable inside the filter chamber.

[0006] Preferably, the filter chamber is connected to the discharge pipe.

[0007] Preferably, an inner groove is horizontally formed on the inner wall of the filter frame.

[0008] Preferably, inner sliders are installed on both sides of the upper surface of the filter screen, and the inner sliders are slidably installed in accordance with the inner grooves.

[0009] Preferably, the outer wall of the inner slider is provided with a plurality of limiting holes spaced apart.

[0010] Preferably, the outer wall of the filter frame is provided with a limiting component for connecting the filter screen, and the limiting component includes an adjusting screw.

[0011] Preferably, the end of the adjusting screw is rotatably connected to a drive rod, which slides horizontally along the inner wall of the filter frame.

[0012] Preferably, a plurality of limiting blocks are fixedly installed at the end of the drive rod away from the adjusting screw, and the limiting blocks are adapted to the limiting holes.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, the adhesive is stirred by the stirring blades, which effectively breaks up viscous clumps, allowing the adhesive to pass through the filter screen more evenly. The semi-circular arc structure of the filter screen ensures that the discharge is concentrated at the bottom of the screen, preventing clogging. The filter screen also features a movable and detachable design, with an inner slider and inner groove that slide together, and a limiting component that secures the screen. This makes installation and removal of the filter screen simple and quick. Regular cleaning or replacement of the filter screen ensures that the filtration device maintains good filtration performance and extends the equipment's lifespan. Attached Figure Description

[0023] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a filtration device, including a filter frame 1. A feed pipe 6 is provided on the upper surface of the filter frame 1, and a cover 2 is rotatably mounted on the side wall of the filter frame 1. A drive motor 5 is mounted on the side wall of the filter frame 1, and the drive motor 5 is distributed opposite to the cover 2. A discharge pipe 3 is installed below the filter frame 1. The filter frame 1 has a filter chamber 7 inside, and a movable and detachable filter screen 10 is provided inside the filter chamber 7. The filter screen 10 has a semi-circular ring structure, and a stirring blade 9 is provided at the center of the filter screen 10 inside the filter chamber 7. Multiple sets of stirring blades 9 are arranged around the filter, and a rotating shaft 8 is fixedly connected to the center. The rotating shaft 8 is horizontally rotatably mounted inside the filter chamber 7. The filter chamber 7 is connected to the discharge pipe 3, and an inner sliding groove 11 is horizontally opened on the inner wall of the filter frame 1. Inner sliders 13 are respectively installed on the two side walls of the upper surface of the filter screen 10, and the inner sliders 13 are adapted to slide in the inner sliding groove 11.

[0024] Multiple limiting holes 12 are spaced apart on the outer wall of the inner slider 13.

[0025] like Figure 3 , Figure 4 , Figure 5 As shown, a limiting assembly 4 for connecting the filter screen 10 is provided on the outer wall of the filter frame 1. The limiting assembly 4 includes an adjusting screw 15, and a drive rod 16 is rotatably connected to the end of the adjusting screw 15. The drive rod 16 slides horizontally along the inner wall of the filter frame 1. A plurality of limiting blocks 14 are fixedly installed at the end of the drive rod 16 away from the adjusting screw 15. The limiting blocks 14 are adapted to the limiting holes 12.

[0026] The working principle of the technical solution provided by this utility model is as follows: Solvent-free polyurethane adhesive enters the filter chamber 7 through the feed pipe 6 on the upper surface of the filter frame 1. The drive motor 5 starts, causing the rotating shaft 8 to rotate horizontally. This causes multiple sets of stirring blades 9, which are arranged around the rotating shaft 8, to rotate within the filter chamber 7. The stirring blades 9 stir the adhesive entering the filter chamber 7, breaking up viscous clumps caused by storage environment or specific formulation, making it easier for the adhesive to pass through the filter screen 10. On the other hand, the power generated by stirring assists the adhesive in passing through the filter screen 10, avoiding the accumulation of adhesive in the filter screen 10 due to gravity when relying solely on gravity for filtration, which increases the risk of clogging. After being filtered through the filter screen 10, the adhesive is discharged from the device through the discharge pipe 3, which is connected to the filter chamber 7, completing the entire filtration process.

[0027] The filter screen 10 has a semi-circular ring structure, with inner sliders 13 installed on both sides of its upper surface. An inner sliding groove 11 is horizontally opened on the inner wall of the filter frame 1. The inner sliders 13 are adapted to slide in the inner sliding groove 11, which facilitates the installation and removal of the filter screen 10 and makes it easy to clean or replace the filter screen 10 regularly. After the filter screen 10 is installed in place, the adjusting screw 15 in the limiting assembly 4 is rotated to drive the drive rod 16 to slide horizontally along the inner wall of the filter frame 1. Multiple limiting blocks 14 fixedly installed at one end of the drive rod 16 are inserted into the limiting holes 12 on the outer wall of the inner slider 13 to limit and fix the filter screen 10, ensuring the stability of the filter screen 10 during the filtration process.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
