Description

Technical Field

[0001] The utility model belongs to the technical field related to the manufacture of styrene-butadiene rubber, and in particular relates to a filtering screen for styrene-butadiene rubber. Background Art

[0002] Styrene butadiene rubber is a synthetic rubber foam with the characteristics of shockproof, heat preservation, elasticity, impermeability, and airtightness. Therefore, it is widely used in the manufacture of waterproof materials. In recent years, with the continuous reduction of costs and the vigorous promotion of many professional finished product manufacturers, it has become a new material with a continuously expanding application field. In the process of styrene butadiene rubber stacking after processing, it is easy to have large impurities and fine iron filings between rubber particles due to the production environment. If it is not effectively screened, it is easy to affect the quality of the finished waterproof membrane.

[0003] For example, patent application number CN201821905388.X discloses an SBR styrene butadiene rubber filter screen, comprising a square outer shell that passes through from top to bottom, a filter screen for filtering large impurities, a coil assembly fixedly connected to the inner wall of the outer shell, a small hot air blower arranged on the inner wall of the side of the outer shell, and an adsorption assembly arranged at the bottom of the outer shell. The utility model adopts two-step filtration. The filter screen filters larger impurities, and uses the principle of electromagnetic induction to remove small iron filings impurities. The adsorption of impurities is controlled by turning on and off the coil assembly, which is easy to clean and has efficient filtration. High-purity SBR styrene butadiene rubber can be obtained, and the surface quality of the produced waterproof membrane is better and the flatness is high.

[0004] In the prior art, large particles of impurities and fine iron filings can be screened out through two-step filtration using electromagnetic adsorption technology and a filter net. However, there are still certain deficiencies in the overall use process: first, a large amount of impurities accumulate on the surface of the filter net after long-term use, so it needs to be cleaned. The prior art lacks a structure that can automatically clean the filter net, and it needs to be disassembled and replaced, affecting production efficiency; secondly, the adsorption process is carried out during the falling process of the iron filings, and the overall efficiency is low, and there is a phenomenon of incomplete adsorption. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a filter screen for styrene-butadiene rubber. The utility model arranges a brush cylinder, an arc-shaped scraper and a dust suction seat so that the outside of the sieve plate can be effectively cleaned after the screening process is completed. The arrangement of the electromagnetic device and the magnetic conductive plate allows the sieve plate to be magnetically conductive when screening large particles of impurities, so that small particles of iron filings can also be adsorbed, and the overall filtering efficiency is effectively guaranteed.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filter screen for styrene-butadiene rubber, comprising a box body, a supporting plate, supporting plates are arranged on both side end surfaces of the box body, a plurality of vibrators are arranged on the end surfaces of the supporting plates, a clamping seat is connected to the output end of the plurality of vibrators on the same side, a detachable screen plate is arranged above the box body between the two clamping seats, a connecting frame is slidably arranged above the two clamping seats, a brush cylinder is rotatably arranged between the two connecting frames, a plurality of bristles are arranged on the outer circumferential surface of the brush cylinder, an electromagnetic device is arranged on both side end surfaces of the clamping seat, a magnetic conductive plate is connected to the output end of the electromagnetic device, and the end surface of the magnetic conductive plate abuts against the side wall of the screen plate. The arrangement of the brush cylinder enables the end surface of the screen plate to be automatically cleaned, and the arrangement of the electromagnetic device and the magnetic conductive plate enables the screen plate to adsorb iron filings, thereby improving the filtering effect.

[0007] Preferably, a linear drive is provided on the end surface of the supporting plate, a connecting frame is connected to the output end of the linear drive, and a positioner is provided on the end surface of the connecting frame. The setting of the connecting frame enables the brush cylinder to effectively clean all parts of the end surface of the sieve plate.

[0008] Preferably, the two ends of the sieve plate are provided with sliders, and the outer side of the slider is provided with a slide groove cooperating therewith in the clamping seat. The arrangement of the slider and the slide groove enables the sieve plate to be quickly disassembled and installed.

[0009] Preferably, a plurality of fixing holes are arranged on the outer end surface of the clamping seat, and a detachable fixing rod is arranged in each of the fixing holes. The setting of the fixing rod ensures the fixing effect of the sieve plate.

[0010] Preferably, a dust suction seat is connected between the two connecting frames on one side of the brush cylinder, and a bell mouth is arranged on the bottom end surface of the dust suction seat. The arrangement of the dust suction seat and the bell mouth enables the dirt washed out by brushing to be cleaned smoothly.

[0011] Preferably, an upwardly curved scraper is provided below the dust suction seat, and one end of the bottom of the curved scraper is close to the end surface of the sieve plate.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0026] Embodiment 1:

[0027] refer to Figure 1-8A filter screen for styrene-butadiene rubber comprises a box body 10 and a supporting plate 19. Supporting plates 19 are arranged on both side end surfaces of the box body 10. A plurality of vibrators 21 are arranged on the end surfaces of the supporting plates 19. A clamping seat 15 is connected to the output end of the plurality of vibrators 21 on the same side. A detachable sieve plate 11 is arranged above the box body 10 between the two clamping seats 15. Connecting frames 13 are slidably arranged above the two clamping seats 15. A brush cylinder 14 is rotatably arranged between the two connecting frames 13. A plurality of bristles 24 are arranged on the outer circumferential surface of the brush cylinder 14. Electromagnets 29 are arranged on both side end surfaces of the clamping seats 15. A magnetic conductive plate 30 is connected to the output end of the electromagnetic 29. The end surface of the magnetic conductive plate 30 abuts against the side wall of the sieve plate 11.

[0028] Specifically, the box body 10 is frame-shaped as a whole, and a mounting hole plate is provided on the bottom end surface. The box body 10 can be fixedly placed at the feed inlet of the forming device, and the sieve plate 11 completes the screening of large particles of impurities in the raw material. In this solution, the sieve holes on the surface of the sieve plate 11 are of the standard size of raw material particles, so that the raw material can enter the box body 10 and be discharged outward, while the large particles of impurities will be screened out by the sieve plate 11. The legend is only for representation, without too much restriction;

[0029] When the raw materials need to be screened, the staff pours the raw materials on the end surface of the sieve plate 11, and the vibrator 21 is started. The vibrator 21 is a prior art, including a linear motor that can generate high-frequency vibration when powered on, etc. This article does not make too many restrictions, and the selection and setting are carried out according to actual needs. The vibrator 21 will vibrate the clamping seat 15 at high frequency, thereby vibrating the sieve plate 11 between the two clamping seats 15 at high frequency, so that the raw materials can be shaken, completing the vibration screening process;

[0030] During the screening process, the magnetic plate 30 on the output end of the electromagnetic device 29 will always abut against the side wall of the sieve plate 11. The electromagnetic device 29 can generate magnetic force when it is energized, so that the magnetic plate 30 and the abutting sieve plate 11 generate a certain magnetic force. At this time, the sieve plate 11 as a whole has a certain magnetic force, which can absorb small iron filings and impurities, so that small iron filings and impurities will not enter the box body 10, effectively improving the filtering effect and quality;

[0031] During the screening process, the connecting frame 13 can drive the stationary brush barrel 14 to move above the sieve plate 11. The non-rotating brush barrel 14 can flatten the accumulated raw materials, so that the vibration can be effectively transmitted, thereby improving the vibration screening efficiency. When the screening is completed, the vibrator 21 continues to be turned on. At this time, the brush barrel 14 will rotate, thereby driving the multiple bristles 24 on the outer cylindrical surface to rotate, thereby brushing the dust and dirt on the end face of the sieve plate 11. During this process, the opening of the vibrator 21 makes the sieve plate 11 still in a vibrating state, which can better shake out dust and dirt, improve the cleaning effect, and ensure subsequent screening processing. In this relationship, the legend only indicates that bristles 24 are arranged on the outside of the brush barrel 14, and does not limit the number, shape, size, etc. of the bristles 24. The settings can be changed according to actual needs.

[0032] refer to Figure 1-4 A linear driver 12 is arranged on the end surface of the supporting plate 19 , a connecting frame 13 is connected to the output end of the linear driver 12 , and a positioner 17 is arranged on the end surface of the connecting frame 13 .

[0033] Specifically, the linear drive 12 is a prior art and will not be elaborated in detail in this article. The output end of the linear drive 12 can drive the connecting frame 13 to move, so that the brush cylinder 14 can be moved to various places on the end surface of the sieve plate 11, which can effectively avoid the occurrence of cleaning dead corners, and the positioner 17 can monitor and control the moving position of the connecting frame 13, so that various places on the end surface of the sieve plate 11 can be effectively cleaned.

[0034] refer to Figure 6 A driving motor 25 is arranged on one end surface of the connecting frame 13 , and an output end of the driving motor 25 is connected to the end surface of the brush cylinder 14 .

[0035] Specifically, the driving motor 25 is a prior art and will not be elaborated in detail herein. The output end of the driving motor 25 can drive the brush cylinder 14 to rotate, thereby completing the brushing process of the sieve plate 11 .

[0036] refer to Figure 5 A dust collecting seat 20 is connected between the two connecting frames 13 on one side of the brush cylinder 14 , and a bell mouth 22 is arranged on the bottom end surface of the dust collecting seat 20 .

[0037] Specifically, the dust suction seat 20 is externally connected to a pump, and when the brush cylinder 14 rotates and scrubs, suction can be generated inside the dust suction seat 20, so that the adsorbed dirt can be sucked away through the bell mouth 22 on the bottom end surface, thereby completing the effective cleaning of the screen plate 11.

[0038] refer to Figure 7 Slide blocks 27 are provided at both ends of the sieve plate 11 , and slide grooves 26 cooperating therewith are provided on the outer sides of the slide blocks 27 in the clamping seat 15 .

[0039] Specifically, the slide groove 26 cooperates with the slider 27 so that the sieve plate 11 can slide between the two clamping seats 15 through the slider 27, thereby effectively improving the efficiency of disassembling and assembling the sieve plate 11.

[0040] refer to Figure 7 A plurality of fixing holes 28 are arranged on the outer end surface of the clamping seat 15 , and a detachable fixing rod 16 is arranged in each fixing hole 28 .

[0041] Specifically, a hole position concentric with the fixing hole 28 is provided on the end face of the slider 27. When the slider 27 slides into the inside of the slide groove 26, the staff can insert one end of the fixing rod 16 into the fixing hole 28. One end of the fixing rod 16 will pass through the fixing hole 28 and abut against the hole position on the end face of the slider 27, so that the slider 27 and the screen plate 11 can be fixed, thereby completing the clamping of the screen plate 11.

[0042] Embodiment 2:

[0043] On the basis of or different from the first embodiment, reference Figure 4 Buffer pads 18 are provided at the upper and lower end surfaces of the clamping seat 15.

[0044] Specifically, the buffer pad 18 is made of elastic buffer material and is disposed at the upper and lower end surfaces of the clamping seat 15 to prevent the clamping seat 15 from colliding with the box body 10 or other structures during vibration, thereby ensuring safety in use.

[0045] Embodiment three:

[0046] On the basis of or different from the first embodiment, reference Figure 5 An upwardly curved arc scraper 23 is arranged below the dust suction seat 20 , and one end of the bottom of the arc scraper 23 is close to the end surface of the sieve plate 11 .

[0047] Specifically, the arc scraper 23 is arranged on one side of the rolling brush cylinder 14 and is located below the dust suction seat 20. The brush cylinder 14 will brush the dust and dirt onto the arc surface of the arc scraper 23. The arc scraper 23 can temporarily hold the dust and dirt, so that the bell mouth 22 can smoothly suck away the dirt. The bottom end of the arc scraper 23 is basically close to the end surface of the screen plate 11, and the dirt on the end surface of the screen plate 11 can also be scraped off, thereby improving the cleaning effect of the screen plate 11.
