Description

Technical Field

[0001] This utility model belongs to the field of PVC adhesive production technology, specifically relating to a filtration device for preparing high-adhesion environmentally friendly PVC floor adhesive. Background Technology

[0002] In the preparation process of environmentally friendly PVC flooring adhesives, colloidal filtration is a core step in ensuring product adhesion, uniformity, and environmental performance. Traditional filtration devices generally suffer from the following technical defects, severely restricting production efficiency and product quality: Traditional equipment lacks a constant temperature heating mechanism, and high-viscosity PVC colloids are prone to localized cooling due to temperature fluctuations during transportation and filtration, forming clumps (experimental data shows a clumping rate as high as 8%-12%). Clumped colloids not only clog the screens but also reduce colloid flowability, leading to a filtration efficiency decrease of more than 30%, requiring frequent shutdowns for cleaning and affecting continuous production. Most equipment relies on manual disassembly of the screens or unidirectional scraper cleaning, requiring shutdown operations (each taking 20-30 minutes), and cannot completely remove impurities embedded in the screen holes (residual clogging rate >15%). During filtration, colloidal particles continuously accumulate on the screen surface, causing the effective filtration area to gradually shrink (screen throughput decreases by 40% after 2 hours of operation), requiring repeated production interruptions.

[0022] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:

[0023] A filtration device for preparing high-adhesion environmentally friendly PVC flooring adhesive, comprising,

[0024] Storage shell 1 and heating shell 2, with heating shell 2 embedded in the inner wall of storage shell 1;

[0025] The heating and filtering assembly is located inside the housing 1. The assembly includes a sealing block 201, a lifting frame 202, a protective shell 3, a drive rod 4, a drive shaft 401, a discharge fan blade 5, a scraper 6, a drive block 7, a cleaning blade 8, a collection hopper 9, a mounting shell 10, a screen 11, and a drive assembly. The sealing block 201 is slidably embedded in the top opening of the heating shell 2. The lifting frame 202 is slidably fitted onto the top of the outer wall of the heating shell 2. The protective shell 3 is fixedly mounted on the bottom of the outer wall of the sealing block 201 via a bracket. The drive rod 4 is rotatably embedded in the lifting frame 202. On the inner wall, the discharge fan blade 5 is rotatably inserted into the outer wall of the drive rod 4 via the bracket. The scraper 6 is sleeved on the outer wall of the bottom end of the drive rod 4. The outer wall of the scraper 6 is attached to the inner wall of the heating shell 2. The drive shaft 401 is fixedly installed on the outer wall of the bottom end of the drive rod 4. The drive block 7 is slidably sleeved on the outer wall of the bottom end of the drive shaft 401. The cleaning blade 8 is fixedly installed on the outer wall of the drive block 7. The collection hopper 9 is embedded in the inner wall of the storage shell 1. The screen 11 is embedded in the inner wall of the mounting shell 10. The screen 11 and the cleaning blade 8 are matched with each other. The drive assembly is embedded in the inner wall of the protective shell 3.

[0026] In a specific embodiment of this utility model, environmentally friendly PVC floor adhesive is injected into the interior of the heating shell 2 through a pipe on the heating shell 2. The heating shell 2 maintains the temperature and prevents clumping. Then, before sieving, the stirring motor 204 is continuously started, driving the drive rod 4 to rotate. The drive rod 4 drives the scraper 6 to continuously scrape the inner wall of the heating shell 2 to prevent adhesion. Subsequently, the driven gear 13 on the discharge fan blade 5 revolves around the gear ring 12, causing the driven gear 13 to rotate, further rotating the discharge fan blade 5. When sieving is required, the lifting cylinder 20 is activated. 3. The guide lifting frame 202 rises, which in turn drives the drive rod 4 to rise. At this time, one end of the drive rod 4 protrudes, releasing the blockage of the discharge port at the bottom of the heating shell 2. The drive rod 4 rises, but the cross-section of the drive block 7 and the drive shaft 401 is a regular hexagon. Therefore, the drive shaft 401 can still drive the drive block 7 to rotate at high speed, causing the environmentally friendly PVC floor adhesive to fall into the inside of the collection hopper 9. At this time, the drive rod 4 continues to rotate, causing the drive block 7 to drive the cleaning blade 8 to rotate continuously, continuously cleaning the outer wall of the screen 11, avoiding a large amount of debris and clumps clogging the screen 11, thus preventing sieving. Efficiency decreases. After completing a batch of production, the screen 11 becomes clogged, and a large amount of clumps clog the collection hopper 9. The drive rod 4 resets, blocking the discharge port at the bottom of the heating shell 2. At this time, the cleaning pipe 101 supplies high-pressure air to clean the screen 11, pulling the drain plug 102 to discharge the clumps and other impurities from the collection hopper 9. Finally, the collection hopper 9 is connected to an external collection device, and the drain plug 102 is used again to supply cleaning solvent and high-pressure air to clean and unclog the screen holes of the screen 11. Impurities, air, and solvent are discharged through the collection hopper 9, and the scraper 6 at the bottom of the drive rod 4 follows. The rotating blades closely adhere to the inner wall of the heating shell 2, continuously scraping away the attached colloids to reduce material waste and maintain stable heating efficiency. When the drive rod 4 rises and falls, the hexagonal drive shaft 401 drives the cleaning blades 8 to rotate at high speed, scraping away blockages on the surface of the screen 11 in real time to ensure the screen hole throughput. The cleaning pipe 101 is connected to high-pressure air and solvent, and with the rapid opening and closing of the drain plug 102, deep cleaning of the screen 11 is achieved. Maintenance can be completed without disassembly, saving 70% of manual cleaning time. At the same time, the screen 11 is continuously cleaned and pushed during filtration to prevent the agglomerated raw materials from clogging the screen 11 and causing a decrease in sieving efficiency.

[0027] Specifically, the drive assembly includes a gear ring 12 and a driven gear 13.

[0028] In a specific embodiment of this utility model, the drive component can ensure continuous high-torque drive of the discharge fan blade 5.

[0029] Specifically, the gear ring 12 is embedded in the inner wall of the protective shell 3, and the driven gear 13 is fixedly installed at the center of the outer wall of the top of the discharge fan blade 5. The gear ring 12 and the driven gear 13 are meshed and connected for transmission.

[0030] In a specific embodiment of this utility model, the gear ring 12 and the driven gear 13 are meshed and connected to ensure transmission accuracy.

[0031] Specifically, lifting cylinders 203 are fixedly installed on both sides of the top of the outer wall of the heating shell 2, and the output end of the lifting cylinder 203 is fixedly installed at the bottom of the outer wall of the lifting frame 202. A stirring motor 204 is fixedly installed at the center of the top of the outer wall of the lifting frame 202, and the output end of the stirring motor 204 is fixedly installed at the center of the top outer wall of the drive rod 4.

[0032] In a specific embodiment of this utility model, the output end of the stirring motor 204 is fixedly located at the center of the top outer wall of the drive rod 4, which can ensure the stable rotation of the drive rod 4.

[0033] Specifically, a drain plug 102 is slidably embedded in the inner wall openings of the storage shell 1 and the collection hopper 9.

[0034] In a specific embodiment of this utility model, the drain plug 102 can ensure sealing while facilitating the quick discharge of debris during the cleaning of the screen 11.

[0035] Specifically, the inner wall openings of the storage shell 1 and the collection hopper 9 are fitted with cleaning pipes 101, and the input end of the cleaning pipes 101 is connected to an external cleaning gas supply device via a hose and a valve.

[0036] In a specific embodiment of this utility model, the inner wall openings of the housing 1 and the collecting hopper 9 are fitted with cleaning tubes 101, which can ensure the rapid injection of cleaning air and solvent, and the collecting hopper 9 has a sealing function to prevent leakage.

[0037] Working principle:

[0038] Environmentally friendly PVC floor adhesive is injected into the interior of the heating shell 2 through the pipes on the heating shell 2. The heating shell 2 maintains the temperature and prevents clumping. Before sieving, the stirring motor 204 is continuously started, driving the drive rod 4 to rotate. The drive rod 4 drives the scraper 6 to continuously scrape the inner wall of the heating shell 2 to prevent adhesion. Then, the driven gear 13 on the discharge fan blade 5 revolves around the gear ring 12, causing the driven gear 13 to rotate, further rotating the discharge fan blade 5. When sieving is required, the lifting cylinder 203 is activated, guiding the lifting frame 202 to rise, which in turn drives the drive rod 4 to rise. At this time, one end of the drive rod 4 protrudes, releasing the blockage of the discharge port at the bottom of the heating shell 2. The drive rod 4 rises, but the cross-section of the drive block 7 and the drive shaft 401 is hexagonal, so the drive shaft 401 can still drive the drive... The moving block 7 rotates at high speed, causing the environmentally friendly PVC floor adhesive to fall into the collection hopper 9. At this time, the drive rod 4 continues to rotate, causing the drive block 7 to drive the cleaning blade 8 to rotate continuously, continuously cleaning the outer wall of the screen 11, preventing a large amount of debris and clumps from clogging the screen 11 and reducing the screening efficiency. After completing a batch of production, the screen 11 will become clogged, and a large amount of clumps will clog the collection hopper 9. The drive rod 4 will reset, causing the bottom discharge port of the heating shell 2 to be blocked. At this time, the cleaning pipe 101 supplies high-pressure air to clean the screen 11, pulling the drain plug 102, allowing the collection hopper 9 to discharge clumps and other impurities. Finally, the collection hopper 9 is connected to an external collection device, and the drain plug 102 is used again to supply cleaning solvent and high-pressure air to complete the cleaning and unblocking of the screen holes of the screen 11. Impurities, air and solvent are discharged through the collection hopper 9.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
