Description

Technical Field

[0001] This application relates to the field of silicone rubber production technology, and in particular to a meterable silicone rubber filtration device. Background Technology

[0002] Silicone rubber is a type of rubber whose main chain consists of alternating silicon and oxygen atoms, with two organic groups typically attached to each silicon atom. Ordinary silicone rubber is mainly composed of siloxane chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve its temperature and oil resistance. Silicone rubber has good low-temperature resistance, generally remaining functional at -55°C. With the introduction of phenyl groups, it can reach -73°C.

[0003] Silicone rubber production requires filtration, but existing metering silicone rubber filtration equipment is inconvenient to clean the filtered impurities during the actual process. Prolonged filtration leads to the accumulation of a large amount of impurities, which in turn affects the filtration efficiency of the equipment. Utility Model Content

[0004] To address the problem of inconvenient cleaning and impurity removal in existing filtration equipment, this application provides a meterable silicone rubber filtration device.

[0005] This application provides a meterable silicone rubber filter device, including a base, a conveying pipe installed on the base, and a feeding mechanism installed on the conveying pipe. The feeding mechanism includes a feeding hopper installed on the conveying pipe, and the feeding hopper and the conveying pipe are connected. The same mounting frame is fixedly connected to the inner walls of both sides of the feeding hopper, and a filter screen is fixedly connected to the inner wall of the mounting frame. Cleaning components are slidably arranged on the inner walls of both sides of the feeding hopper. A slag discharge port is opened on one outer wall of the feeding hopper, and a sealing plate is hinged to the inner wall of the slag discharge port. Two symmetrically arranged handles are fixedly connected to one outer wall of the sealing plate.

[0006] By adopting the above structure, the installation frame in the feeding mechanism facilitates the installation of the filter screen. The filter screen facilitates the initial filtration of the silicone rubber liquid injected into the feeding hopper. Long-term filtration will cause a large amount of impurities to adhere to the filter screen. The cleaning component facilitates the removal of impurities from the filter screen. The removed impurities can be directly discharged through the slag discharge port. The sealing plate facilitates the sealing of the slag discharge port to prevent leakage of silicone rubber raw materials.

[0007] The cleaning assembly includes a cleaning seat slidably connected to the inner wall of the hopper, and the inner wall of the cleaning seat has an installation cavity. A drive seat is slidably connected to the inner wall of the installation cavity, and the cross-section of the drive seat is T-shaped.

[0008] By adopting the above structure, the drive seat can be easily slidably installed by cleaning the mounting cavity in the seat, and the T-shaped drive seat can effectively prevent it from falling out of the mounting cavity.

[0009] A scraper is fixedly connected to the bottom outer wall of the drive seat, and the scraper is in contact with the filter screen.

[0010] By adopting the above structure, the installation of the scraper is convenient through the setting of the drive seat. The scraper can easily clean the impurities adhering to the filter screen, thereby preventing the filter screen from being blocked by impurities.

[0011] The same bidirectional screw is rotatably connected to the inner walls of both sides of the mounting cavity, and two symmetrically arranged threaded sleeves are screwed onto the outer wall of the bidirectional screw. A connecting plate is rotatably connected to the outer wall of each of the two threaded sleeves, and one end of each connecting plate is rotatably connected to the drive seat.

[0012] By adopting the above structure, the installation cavity facilitates the rotational installation of the bidirectional screw. When the bidirectional screw rotates, it directly drives the two threaded sleeves to move towards or away from each other. When the two threaded sleeves move towards each other, they directly push the drive seat down through the connecting plate, thereby driving the scraper to move.

[0013] A U-shaped mounting bracket is fixedly connected to the top inner wall of the mounting cavity, and a bidirectional screw is rotatably connected to the mounting bracket.

[0014] By adopting the above structure, the mounting bracket facilitates the auxiliary installation of the bidirectional screw, thereby ensuring the stability of the bidirectional screw.

[0015] A worm gear is fixedly connected to the midpoint of the bidirectional screw. A worm is rotatably connected to the inner wall of one side of the mounting cavity, and the worm and the worm gear mesh with each other. A rotating disk is rotatably connected to the top outer wall of the cleaning seat, and one end of the rotating disk's drive shaft is fixedly connected to the worm. Two symmetrically arranged electric slide rails are fixedly connected to the top outer wall of the feeding hopper, and the cleaning seat is slidably connected to the two electric slide rails.

[0016] By adopting the above structure, the rotating disk directly drives the worm to rotate, the worm to rotate, and the worm to rotate, which in turn drives the bidirectional screw to rotate, thus facilitating the direct drive of the two threaded sleeves on the bidirectional screw. The electric slide rail facilitates the direct drive of the cleaning seat to reciprocate, thereby facilitating the cleaning of impurities on the filter screen.

[0017] A feeding pipe is fixedly connected to one side of the outer wall of the base, and the same flow meter is installed between the feeding pipe and the conveying pipe. A control box is fixedly connected to one side of the outer wall of the base.

[0018] By adopting the above structure, the filtered silicone rubber liquid is discharged through the feed pipe via the delivery pipe, and the flow meter facilitates real-time and accurate measurement of the flow rate of the filtered silicone rubber.

[0019] In summary, the beneficial effects of this application are as follows:

[0020] 1. This application provides a filter screen on the feeding mechanism and a cleaning component in the feeding hopper. The cleaning component facilitates the removal of impurities adhering to the filter screen. Furthermore, an openable sealing plate is provided on the feeding hopper, allowing the impurities removed by the cleaning component to be discharged directly when the sealing plate is opened.

[0021] 2. This application provides an adjustable drive seat in the cleaning unit, which allows for easy adjustment of the scraper's position. The scraper facilitates the removal of impurities adhering to the filter screen. Furthermore, the cooperation between the bidirectional screw, threaded sleeve, and connecting plate facilitates the adjustment of the scraper's position, thereby avoiding large gaps between the scraper and the filter screen and improving the scraper's cleaning efficiency.

The feeding hopper 7 is connected to the conveying pipe 3, and the same mounting frame 10 is fixedly connected to the inner walls of both sides of the feeding hopper 7. A filter screen 11 is fixedly connected to the inner wall of the frame 10. The frame 10 is designed to facilitate the fixed installation of the filter screen 11. Cleaning components 13 are slidably installed on the inner walls of both sides of the feeding hopper 7. The cleaning components 13 are designed to facilitate the cleaning of impurities adhering to the filter screen 11. A slag discharge port is opened on one outer wall of the feeding hopper 7. The slag discharge port is designed to facilitate the direct discharge of impurities filtered out of the filter screen 11. A sealing plate 8 is hinged to the inner wall of the slag discharge port. Two symmetrically arranged handles 9 are fixedly connected to one outer wall of the sealing plate 8. The handles 9 are designed to facilitate the opening of the sealing plate 8. The sealing plate 8 is designed to facilitate the sealing of the slag discharge port, thereby preventing the leakage of silicone rubber in the feeding hopper 7.

[0029] In use, the filter screen 11 is easily installed through the mounting frame 10 in the feeding mechanism 6. The filter screen 11 facilitates the initial filtration of the silicone rubber liquid injected into the feeding hopper 7. Long-term filtration of the filter screen 11 will cause a large amount of impurities to adhere to it. The cleaning component 13 facilitates the removal of impurities from the filter screen 11.

The scraper 17 has a trapezoidal cross-section and is in contact with the filter screen 11.

[0032] Reference Figure 4 The same bidirectional screw 19 is rotatably connected to the inner walls of both sides of the mounting cavity 15. The bidirectional screw 19 is horizontally mounted on the inner wall of the mounting cavity 15, and two symmetrically arranged threaded sleeves 20 are screwed to the outer wall of the bidirectional screw 19. When the bidirectional screw 19 rotates, it directly drives the two threaded sleeves 20 to move towards or away from each other. The outer walls of the two threaded sleeves 20 are rotatably connected to connecting plates 21. By setting the connecting plates 21 on the outer walls of the threaded sleeves 20, it is convenient to restrict the rotation of the threaded sleeves 20 with the bidirectional screw 19. One end of each connecting plate 21 is rotatably connected to the drive seat 16. When the bidirectional screw 19 rotates, it directly drives the two drive seats 16 to move towards or away from each other. When the two threaded sleeves 20 move towards each other, the drive seat 16 is pushed down directly through the connecting plate 21. When the two threaded sleeves 20 move away from each other, the drive seat 16 is pulled up directly through the connecting plate 21. When the drive seat 16 moves down, it drives the scraper 17 closer to the filter screen 11. When the drive seat 16 moves up, it drives the scraper 17 away from the filter screen 11. The mounting cavity 15 facilitates the rotation and installation of the bidirectional screw 19. When the bidirectional screw 19 rotates, it directly drives the two threaded sleeves 20 to move towards or away from each other. When the two threaded sleeves 20 move towards each other, the drive seat 16 is pushed down directly through the connecting plate 21, thereby driving the scraper 17 to move.

[0033] Reference Figure 4 A U-shaped mounting bracket 18 is fixedly connected to the top inner wall of the mounting cavity 15. The U-shaped mounting bracket 18 facilitates the auxiliary installation of the bidirectional screw 19. The bidirectional screw 19 is rotatably connected to the mounting bracket 18. The mounting bracket 18 improves the stability of the bidirectional screw 19. The mounting bracket 18 facilitates the auxiliary installation of the bidirectional screw 19, thereby ensuring the stability of the bidirectional screw 19.

[0034] Reference Figure 4A worm gear 22 is fixedly connected at the midpoint of the bidirectional screw 19. The worm gear 22 is located at the midpoint of the bidirectional screw 19 to avoid affecting the movement of the two threaded sleeves 20. A worm 23 is rotatably connected to one side of the inner wall of the mounting cavity 15, and the worm 23 and worm gear 22 mesh with each other. The rotation of the worm 23 directly drives the rotation of the worm gear 22. When the worm gear 22 rotates, it conveniently and directly drives the bidirectional screw 19 to rotate, which in turn drives the drive seat 16 to move through the threaded sleeves 20 and the connecting plate 21. A rotating disk 24 is rotatably connected to the top outer wall of the cleaning seat 14, and one end of the drive shaft of the rotating disk 24 is fixedly connected to the worm 23. The rotating disk 24 is conveniently and directly connected to the worm 23. The worm gear 23 is manually driven to rotate. Two symmetrically arranged electric slide rails 12 are fixedly connected to the top outer wall of the feeding hopper 7. The cleaning seat 14 is slidably connected to the two electric slide rails 12. The electric slide rails 12 are designed to directly drive the cleaning seat 14 to move back and forth in the feeding hopper 7. The rotating disk 24 directly drives the worm gear 23 to rotate. When the worm gear 23 rotates, it directly drives the worm wheel 22 to rotate. When the worm wheel 22 rotates, it directly drives the bidirectional screw 19 to rotate, which in turn directly drives the two threaded sleeves 20 on the bidirectional screw 19 to move. The electric slide rails 12 are designed to directly drive the cleaning seat 14 to move back and forth, which in turn facilitates the cleaning of impurities on the filter screen 11.

[0035] Reference Figure 1-2 A discharge pipe 5 is fixedly connected to one outer wall of the base 1. The discharge pipe 5 facilitates the direct discharge of the filtered silicone rubber raw material. A flow meter 4 is installed between the discharge pipe 5 and the conveying pipe 3. The flow meter 4 is connected to the conveying pipe 3 and the discharge pipe 5, which facilitates the detection of the flow rate of the silicone rubber discharged from the conveying pipe 3. A control box 2 is fixedly connected to one outer wall of the base 1. The control box 2 facilitates the control of the electrical components in the filtration device. The filtered silicone rubber liquid is discharged through the discharge pipe 5 via the conveying pipe 3. The flow meter 4 facilitates the real-time and accurate measurement of the flow rate of the filtered silicone rubber.

[0036] The implementation principle of this application is as follows: In use, molten silicone rubber liquid is first injected into the feeding hopper 7. The liquid is then filtered through the filter screen 11. The filtered silicone rubber liquid directly enters the conveying pipe 3. The flow rate of the silicone rubber liquid in the conveying pipe 3 is monitored by the flow meter 4 on the conveying pipe 3. After the filter screen 11 has been filtering for a period of time, the impurities adhering to the filter screen 11 need to be cleaned. During cleaning, the electric slide rail 12 is activated, directly driving the cleaning component 13 to reciprocate within the feeding hopper 7. As the cleaning component 13 moves, it directly drives the scraper 17 to clean the impurities adhering to the filter screen 11. Impurities adhering to the filter screen 11 are pushed to the slag discharge port. When discharging slag, the sealing plate 8 is opened directly to facilitate the direct discharge of the filtered impurities. Long-term filtration will cause gaps to appear between the scraper 17 and the filter screen 11. At this time, the rotating disk 24 rotates, driving the worm 23 to rotate. When the worm 23 rotates, it directly drives the worm wheel 22 to rotate. When the worm wheel 22 rotates, it directly drives the bidirectional screw 19 to rotate. When the bidirectional screw 19 rotates, it directly drives the two threaded sleeves 20 on it to move towards or away from each other. When the two threaded sleeves 20 move towards each other, they directly push the drive seat 16 down through the connecting plate 21. When the drive seat 16 moves down, it directly drives the scraper 17 to contact the filter screen 11.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
