Detailed Implementation

[0024] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The polymer material filtration system of this application embodiment will now be described with reference to the accompanying drawings.

[0026] like Figures 1-3 As shown, the polymer material filtration system of this application embodiment may include a support frame 10, a cylinder 20, a collection box 30, a first filtration device 40, a second filtration device 50, a reciprocating motion mechanism 60, and a cleaning mechanism 70.

[0027] The cylinder 20 is mounted on the support frame 10, and a discharge port 21 is provided at the bottom of the cylinder 20. The collection box 30 is located below the discharge port 21. It should be noted that the cylinder 20 described in this embodiment is sealed at both ends.

[0028] It should be noted that the bottom wall of the inner cavity of the collection box 30 described in this embodiment may be a downward sloping surface, so as to facilitate the discharge and collection of the secondary polymer material reaction raw materials collected in the collection box 30.

[0029] The first filter device 40 is rotatably disposed inside the cylinder 20. The first filter device 40 is used to filter primary impurities in the raw material for the polymer reaction to obtain primary polymer raw material. It should be noted that, in this embodiment, the raw material for the polymer reaction to be filtered can be crushed natural rubber blocks.

[0030] It should be noted that the primary impurity described in this embodiment can be a larger impurity (such as gravel), while the primary polymer material reaction raw material is a polymer material reaction raw material for which larger impurities have been removed.

[0031] The second filter device 50 is oscillatingly disposed within the collection box 30. The second filter device 50 is used to filter secondary impurities in the primary polymer material reaction raw materials to obtain the secondary polymer material reaction raw materials.

[0032] It should be noted that the secondary impurities described in this embodiment can be relatively small impurities, and the raw materials for the secondary polymer material reaction can be raw materials for the polymer material reaction after removing the relatively small impurities.

[0033] The reciprocating motion mechanism 60 is mounted on the cylinder 20, and one end of the reciprocating motion mechanism 60 is connected to the other end of the first filter device 40 through the first belt drive mechanism. The first filter device 40 is used to drive the reciprocating motion mechanism 60 to move through the first belt drive mechanism.

[0034] One end of the cleaning mechanism 70 is connected to the reciprocating motion mechanism 60, and the other end of the cleaning mechanism 70 is movably connected to the first filter device 40 and the second filter device 50 respectively. The reciprocating motion mechanism 60 is used to drive the cleaning mechanism 70 to perform reciprocating motion in order to clean the first filter device 40 and the second filter device 50.

[0035] Specifically, when it is necessary to filter the raw materials for the polymer reaction, the relevant personnel first need to set up the polymer filtration system at the location of the raw materials (which can be inside the factory where the raw materials are processed). Then, the personnel control a conveying device (which can be a belt conveyor) to transport the raw materials to the first filtration device 40. The personnel then control the first filtration device 40 to rotate inside the cylinder 20. The rotating first filtration device 40 filters out primary impurities in the raw materials and gradually discharges them as it rotates. The resulting primary polymer reaction raw materials are filtered into the cylinder 20 and discharged into the second filtration device 50 through the discharge port 21 at the bottom of the cylinder 20.

[0036] Subsequently, the staff controls the second filtration device 50 to swing back and forth within the collection box 30. This swinging motion filters out secondary impurities from the primary polymer material reaction raw material, which are then gradually discharged as the device swings. The resulting secondary polymer material reaction raw material is discharged into the collection box 30 and collected via the slope at the bottom. By performing multiple filtrations on the polymer material reaction raw material, incomplete filtration can be effectively avoided, thereby significantly improving the filtration quality of the polymer material reaction raw material.

[0037] Meanwhile, the rotating first filter device 40 drives the reciprocating motion mechanism 60 via the first belt drive mechanism. The reciprocating motion mechanism 60 drives the cleaning mechanism 70 to move back and forth, cleaning the first filter device 40 and the second filter device 50 respectively, to remove primary and secondary impurities clogging the first filter device 40 and the second filter device 50. This effectively prevents clogging of the filtration system, improves filtration efficiency, and extends the service life of the filtration system.

[0038] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the first filtration device 40 may include a drum screen 41, two sets of spiral conveying blades 42 and a first drive mechanism 43.

[0039] The drum screen 41 is rotatably disposed inside the cylinder 20. Two sets of spiral conveying blades 42 are respectively disposed on the inner walls of both ends of the drum screen 41. Each set of spiral conveying blades 42 may include multiple spiral conveying blades 42, which are spirally and equidistantly distributed on the inner wall of the drum screen 41 and disposed near the end of the drum screen 41.

[0040] One end of the first drive mechanism 43 is connected to the cylinder 20, and the other end of the first drive mechanism 43 is connected to one end of the drum screen 41 through the second belt drive mechanism. The first drive mechanism 43 drives the second belt drive mechanism to rotate the drum screen 41. It should be noted that the first drive mechanism 43 described in this embodiment can be a motor. The motor body can be mounted on the cylinder 20 using threaded fasteners (screws, bolts, or bolts), and the output shaft of the motor is connected to one end of the drum screen 41 through the second belt drive mechanism.

[0041] It should be noted that the second belt drive mechanism described in this embodiment may include a second driving pulley (not specifically marked in the figure), a second driven pulley (not specifically marked in the figure), and a second belt (not specifically marked in the figure). The second driving pulley is mounted on the output shaft of the motor, the second driven pulley is fitted onto the feed inlet end of the drum screen 41, and the second belt is fitted onto both the second driving pulley and the second driven pulley. That is, when the motor starts, it drives the second driving pulley to rotate. The rotating second driving pulley drives the second driven pulley to rotate via the first belt, thereby causing the drum screen 41 to rotate within the cylinder 20.

[0042] Furthermore, in one embodiment of this application, such as Figure 1 and Figure 3 As shown, the second filter device 50 may include a screen 51, two sets of connecting plates 52, and a second drive mechanism 53.

[0043] The screen 51 is suspended inside the collection box 30. Two sets of connecting plates 52 are respectively arranged on both sides of the screen 51. One end of the two sets of connecting plates 52 is pivotally connected to the screen 51, and the other end of the two sets of connecting plates 52 is pivotally connected to the collection box 30. Each set of connecting plates 52 includes two connecting plates 52, which are symmetrically arranged on one side of the screen 51. One end of the two connecting plates 52 is pivotally connected to the side wall of the screen 51, and the other end of the two connecting plates 52 is pivotally connected to the inner wall of the collection box 30.

[0044] One end of the second drive mechanism 53 is connected to the support frame 10, and the other end of the second drive mechanism 53 is connected to one end of the screen 51 through the transmission mechanism 510. It should be noted that the second drive mechanism 53 described in this embodiment can be a servo motor. The body of the servo motor can be mounted on the support frame 10 by threaded fasteners, and the output shaft of the servo motor is connected to one end of the screen 51 through the transmission mechanism 510.

[0045] It should be noted that the mesh size of the drum screen 41 described in the above embodiment is smaller than that of the screen 51, thereby achieving finer filtration.

[0046] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 1 As shown, the transmission mechanism 510 may include a crank 511 and a connecting rod 512.

[0047] The crank 511 is connected to the other end of the second drive mechanism 53, that is, the crank 511 is set on the output shaft of the servo motor (second drive mechanism 53).

[0048] One end of the connecting rod 512 is pivotally connected to the crank 511, and the other end of the connecting rod 512 is pivotally connected to one end of the screen 51. The connecting rod 512 is eccentrically connected to the crank 511, that is, one end of the connecting rod 512 is eccentrically set on the crank 511.

[0049] Specifically, when the raw material for the polymer reaction to be filtered is introduced (poured) into the drum screen 41 through the feed port, the operator starts the motor (first drive mechanism 43) by controlling the motor. The started motor drives the drum screen 41 to rotate inside the cylinder 20 through the second belt drive mechanism. The rotating drum screen 41 filters the primary impurities in the raw material for the polymer reaction to be filtered into the drum screen 41. As the drum screen 41 rotates gradually, the filtered primary impurities are discharged from the discharge port of the drum screen 41. The filtered primary polymer reaction raw material is screened into the cylinder 20 through the screen holes on the drum screen 41 and discharged into the screen 51 through the discharge port 21 on the cylinder 20.

[0050] Then, the operator controls the servo motor (second drive mechanism 53) to drive the crank 511 to rotate. The rotating crank 511 drives the screen 51 to move back and forth within the collection box 30 via the connecting rod 512. The reciprocating screen 51 filters out secondary impurities from the primary polymer material reaction raw material. As the screen 51 swings back and forth within the collection box 30, the secondary impurities are gradually thrown off the screen 51 (i.e., the secondary impurities on the screen 51 are gradually thrown off by the inertia of the reciprocating swing). The secondary polymer material reaction raw material is discharged into the collection box 30 through the sieve holes on the screen 51. Under its own gravity, the secondary polymer material reaction raw material slides out along the slope on the bottom wall of the collection box 30 for collection by the operator. Thus, by performing secondary filtration on the polymer material reaction raw material to be filtered, incomplete filtration can be effectively avoided, thereby effectively improving the filtration quality of the polymer material reaction raw material.

[0051] In one embodiment of this application, such as Figure 3 As shown, the reciprocating motion mechanism 60 may include a reciprocating lead screw 61 and a slider 62.

[0052] The reciprocating screw 61 is rotatably mounted on the cylinder 20, and one end of the reciprocating screw 61 is connected to the other end of the drum screen 41 through the first belt drive mechanism.

[0053] It should be noted that the first belt drive mechanism described in this embodiment may include a first driving pulley (not specifically marked in the figure), a first driven pulley (not specifically marked in the figure), and a first belt (not specifically marked in the figure). The first driving pulley is located at one end of the reciprocating screw 61, the first driven pulley is sleeved on the discharge end of the drum screen 41, and the first belt is sleeved on both the first driving pulley and the first driven pulley. That is, the rotating drum screen 41 drives the first driving pulley to rotate, and the rotating first driving pulley drives the first driven pulley to rotate via the first belt, thereby driving the reciprocating screw 61 to rotate.

[0054] The slider 62 is movably mounted on the reciprocating lead screw 61, and the slider 62 is connected to one end of the cleaning mechanism 70. It should be noted that the cylinder 20 is provided with a slide (not specifically marked in the figure), and the slider 62 passes through the slide and is connected to one end of the cleaning mechanism 70.

[0055] Furthermore, in one embodiment of this application, such as Figure 3 As shown, the cleaning mechanism 70 may include a collar 71 and a scraper 72.

[0056] The collar 71 is movably fitted onto the drum screen 41, and a brush 710 is provided on the inner wall of the collar 71. The brush 710 abuts against the outer wall of the drum screen 41. The collar 71 is fixedly connected to the slider 62. The collar 71 is used to drive the brush 710 to clean the outer wall of the drum screen 41 to prevent the screen holes on the drum screen 41 from becoming clogged.

[0057] The scraper 72 is movably disposed on the screen 51 and is fixedly connected to the collar 71. The scraper 72 is used to clean the screen 51 to prevent the mesh of the screen 51 from becoming clogged.

[0058] Specifically, when the drum screen 41 rotates, the rotating drum screen 41 drives the reciprocating screw 61 to rotate through the first belt drive mechanism. The rotating reciprocating screw 61 drives the slider 62 to move back and forth along the slide. The back and forth moving slider 62 drives the collar 71 and scraper 72 to move back and forth synchronously. The reciprocating moving collar 71 drives the brush 710 to clean the drum screen 41, so as to scrape off the primary impurities or primary polymer material reaction raw materials that are blocked on the drum screen 41, and prevent the primary impurities or primary polymer material reaction raw materials from blocking the screen holes of the drum screen 41.

[0059] Simultaneously, the scraper 72, moving synchronously with the collar 71, cleans the screen 51 by scraping away primary and secondary polymer reaction raw materials or secondary impurities that are clogging the screen 51, thus preventing these materials from clogging the mesh. This effectively avoids clogging of the screen 51 and the drum screen 41, improving filtration efficiency and extending their service life.

[0060] In one embodiment of this application, such as Figure 4 and Figure 5 As shown, the above-mentioned polymer material filtration system may also include an auxiliary cleaning device 80, which is movably disposed inside the drum screen 41. The auxiliary cleaning device 80 is used to clean the inner wall of the drum screen 41.

[0061] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 4 and Figure 5 As shown, the auxiliary cleaning device 80 may include a first support sleeve 81, a second support sleeve 82, a slide bar 83, a threaded rod 84, a third drive mechanism 85, and a cleaning ring 86.

[0062] The first support sleeve 81 and the second support sleeve 82 are arranged side by side and suspended inside the drum screen 41 along the central axis of the drum screen 41. The first support sleeve 81 and the second support sleeve 82 are respectively fixed at both ends of the cylinder 20, and the openings of the first support sleeve 81 and the second support sleeve 82 are arranged opposite to each other.

[0063] One end of the slide rod 83 is slidably connected to the first support sleeve 81, and the other end of the slide rod 83 is slidably connected to the second support sleeve 82.

[0064] One end of the threaded rod 84 is rotatably connected to the first support sleeve 81, and the other end of the threaded rod 84 passes through the slide rod 83 and the second support sleeve 82 in sequence and is connected to one end of the third drive mechanism 85. The threaded rod 84 is threadedly connected to the slide rod 83.

[0065] It should be noted that the first support sleeve 81 and the second support sleeve 82 described in this embodiment have rhomboid slides respectively opened inside, and the slide rod 83 is a rhomboid slide rod. It can be understood that by setting the rhomboid slide rod in a movably set in the rhomboid slide, when the threaded rod 84 rotates, the rhomboid slide rod can move back and forth in the rhomboid slide, thereby preventing the slide rod from rotating with the threaded rod 84.

[0066] The other end of the third drive mechanism 85 is fixedly connected to the cylinder 20. The third drive mechanism 85 is used to drive the threaded rod 84 to rotate.

[0067] It should be noted that the third drive mechanism 85 described in this embodiment can be a bidirectional servo motor. The body of the bidirectional servo motor can be connected to the cylinder 20 through threaded fasteners, and the output shaft of the bidirectional servo motor is connected to one end of the threaded rod 84.

[0068] The cleaning ring 86 is movably disposed inside the drum screen 41 and is in contact with the inner wall of the drum screen 41. The cleaning ring 86 is fixedly connected to the slide rod 83 through a bracket (not specifically marked in the figure). The cleaning ring 86 is used to clean the inner wall of the drum screen 41.

[0069] Specifically, when the drum screen 41 rotates to filter the raw material for the polymer reaction, the relevant personnel can simultaneously control the bidirectional servo motor (third drive mechanism 85) to start. The started bidirectional servo motor drives the threaded rod 84 to rotate clockwise for a preset time. Then, the bidirectional servo motor drives the threaded rod 83 to rotate counterclockwise. The rotating threaded rod 84 drives the slide rod 83 to move back and forth between the first support sleeve 81 and the second support sleeve 82. The back-and-forth movement of the slide rod 83 drives the cleaning ring 86 to move back and forth along the inner wall of the drum screen 41 through the bracket. This scrapes away the primary impurities or primary polymer reaction raw material that are blocked on the inner wall of the drum screen 41, thereby effectively preventing the drum screen 41 from clogging, effectively improving the filtration efficiency, and extending the service life of the drum screen 41.

[0070] In summary, the polymer material filtration system of this application embodiment can effectively avoid incomplete filtration by filtering the raw materials for polymer material reaction multiple times, thereby effectively improving the filtration quality of the raw materials for polymer material reaction. In addition, it can also effectively prevent clogging of the filtration system and improve filtration efficiency.
