Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically a layered filtration device for the production of water-based hydroxy acrylic emulsion. Background Technology

[0002] In the production of water-based hydroxy acrylic emulsions, filtration is a crucial step in ensuring product quality. Traditional filtration equipment often uses static filter cloths to intercept impurities. Over time, the filter cloth surface accumulates a large amount of polymer gel, unreacted particles, and mechanical impurities, leading to a significant decrease in filtration efficiency, reduced emulsion throughput, and even clogging of the filter cloth pores, affecting product purity and stability. Existing cleaning methods mostly rely on manual disassembly of the filter cloth for rinsing or replacement, which is not only costly in terms of manpower and time, but frequent disassembly can also damage the filter cloth, and there is a risk of secondary contamination during manual cleaning. Furthermore, while some equipment has automatic cleaning functions, the cleaning and collection processes are separated, allowing impurities to remain inside the equipment, resulting in incomplete cleaning.

[0003] Therefore, those skilled in the art have provided a layered filtration device for the production of aqueous hydroxyacrylic acid emulsions to solve the problems mentioned in the background art. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Reference Figures 1-7This embodiment provides a layered filtration device for producing water-based hydroxy acrylic emulsion, including a filter frame 1. A filter cloth 2 is provided at the bottom of the filter frame 1. A left guide rail 3 and a right guide rail 4 are respectively provided on the left and right sides of the filter frame 1. A lead screw 8 is rotatably installed inside the left guide rail 3, and a guide rod 9 is fixedly connected inside the right guide rail 4. A moving block 5 is threaded onto the lead screw 8, and a slider 6 is slidably connected to the guide rod 9. The moving block 5 and the slider 6 are slidably connected to the inner walls of the left and right guide rails, respectively. A crossbeam 7 is fixedly connected to the moving block 5 and the slider 6. Two connecting arms 22 are fixedly connected to the lower end of the crossbeam 7, and a scraper 23 is fixedly connected to the end of each connecting arm 22. The connecting arm 22 is tightly attached to the inner rear wall of the filter frame 1. The bottom of the scraper 23 is provided with an elastic scraper strip, which is in linear contact with the surface of the filter cloth 2. The material of the elastic scraper strip is rubber or silicone. The water-based hydroxy acrylic emulsion flows into the filter frame 1 and is filtered through the filter cloth 2 at the bottom. Impurities are intercepted on the surface of the filter cloth. When the accumulation of impurities on the surface of the filter cloth affects the filtration efficiency, the drive motor 10 drives the lead screw 8 to rotate. The moving block 5 is threaded on the lead screw 8. In conjunction with the slider 6 on the guide rod 9, the crossbeam 7 moves along the left guide rail 3 and the right guide rail 4 from the rear end to the front end of the filter frame 1, so that the connecting arm 22 drives the scraper 23 to move synchronously. The scraper 23 is tightly attached to the surface of the filter cloth and scrapes the impurities to the front end of the filter frame 1.

[0027] Example 2

[0028] Reference Figures 1-7 This embodiment is based on the previous embodiment, but differs in that the front end face of the filter frame 1 is provided with a front guide rail 11, and a second lead screw 12 is rotatably installed inside the front guide rail 11. A second movable block 13 is threadedly connected to the second lead screw 12, and the second movable block 13 is slidably connected to the inner wall of the front guide rail 11. A bracket 14 is fixedly connected to the upper end of the second movable block 13, and a suction pipe 15 is detachably installed on the bracket 14 by means of a clamp. The suction end of the suction pipe 15 extends into the filter frame 1 and is fixedly connected to a suction hood 1. 6. The dust hood 16 is attached to the inner front wall of the filter frame 1; the suction end of the dust suction pipe 15 is fixedly connected to the hose 17 through a quick adapter, and the hose 17 is connected to the external blower; the drive motor 18 drives the lead screw 12 to rotate, causing the moving block 13 to move back and forth along the front guide rail 11, and then drives the dust hood 16 to move back and forth in the front area through the bracket 14. Under the negative pressure generated by the external blower, the dust hood 16 sucks in the impurities scraped by the scraper 23 in time, and transports them to the external collection device through the dust suction pipe 15 and the hose 17.

[0029] Furthermore, a drive motor 10 is fixedly installed at one end of the left guide rail 3, and the output shaft of the drive motor 10 is fixedly connected to the lead screw 8 via a coupling. A drive motor 28 is fixedly installed at one end of the front guide rail 11, and the output shaft of the drive motor 28 is fixedly connected to the lead screw 22 via a coupling. Support legs 20 are fixedly installed at the four corners of the filter frame 1, and receiving plates 19 are fixedly installed on the support legs 20. A slide 21 is provided on one side of the receiving plate 19. The filtered emulsion falls into the receiving plate 19. Utilizing the tilt angle of the receiving plate 19 and the design of the slide 21, the emulsion flows smoothly out of the equipment along the slide 21, completing the entire filtration and cleaning process.

[0030] Furthermore, a touch switch 24 is fixedly installed on the inner walls of both ends of the right guide rail 4, and a touch switch 25 is fixedly installed on the inner walls of both sides of the front guide rail 11.

[0031] Working principle: This invention achieves efficient filtration and automatic cleaning of water-based hydroxy acrylic emulsion through the coordinated operation of multiple components. During the filtration process, the water-based hydroxy acrylic emulsion flows into the filter frame 1, where solid-liquid separation is achieved by the filter cloth 2 at the bottom. The emulsion passes through the filter cloth 2, while impurities are intercepted on the surface of the filter cloth.

[0032] As filtration continues, when excessive impurities accumulate on the filter cloth surface, affecting filtration efficiency, the cleaning process is initiated. The drive motor 10 at one end of the left guide rail 3 starts operating, its output shaft driving the lead screw 8 to rotate via a coupling. Since the lead screw 8 is threadedly connected to the moving block 5, the moving block 5 moves along the lead screw 8 during rotation. Simultaneously, the slider 6 on the guide rod 9 assists the crossbeam 7 in maintaining stable movement. Together, they drive the crossbeam 7 along the left and right guide rails 3 and 4, moving it from the rear end to the front end of the filter frame 1. The connecting arm 22 at the lower end of the crossbeam 7 moves accordingly, thereby driving the scraper 23 to move synchronously. The elastic scraper strip at the bottom of the scraper 23 makes linear contact with the surface of the filter cloth 2, adhering closely to the filter cloth surface during movement and scraping impurities to the front end of the filter frame 1. When the slider touches the touch switch 24 on the inner wall at both ends of the right guide rail 4, the touch switch 24 sends a signal to the external controller. The external controller controls the drive motor 10 to stop rotating, the scraper 23 to stop moving, and controls the drive motor 10 to reverse, so that the scraper 23 returns to the initial position, ready for the next cleaning.

[0033] After the impurities are scraped to the front end, the drive motor 18 at one end of the front guide rail 11 starts, and its output shaft drives the lead screw 12 to rotate through the coupling. The lead screw 12 is threadedly connected to the moving block 13, causing the moving block 13 to reciprocate along the front guide rail 11. The bracket 14 at the upper end of the moving block 13 drives the dust collection hood 16 to move together. The dust collection hood 16 is against the inner wall of the front end of the filter frame 1 and is connected to an external blower through the suction pipe 15 and the hose 17. The external blower generates negative pressure, and when the dust collection hood 16 moves back and forth in the front area, it sucks in the impurities scraped by the scraper 23 in time and transports them to the external collection device through the suction pipe 15 and the hose 17. When the moving block 13 touches the touch switch 25 on both sides of the inner wall of the front guide rail 11, the touch switch 25 sends a signal to the external controller, and the external controller controls the drive motor 18 to reverse, causing the dust collection hood 16 to move in the opposite direction. This reciprocating motion achieves continuous impurity removal.

[0034] The filtered emulsion falls into the receiving plate 19 on the support leg 20. The receiving plate 19 has an inclined angle and, together with the slide 21 opened on one side, allows the emulsion to flow smoothly out of the equipment along the slide 21, thereby completing the entire process of emulsion filtration and impurity removal.
