Detailed Implementation
[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1 to 6 As shown in the figure, this utility model embodiment proposes a filtration device for rosin production, which is used to filter rosin during the rosin production process to remove impurities from the rosin.
[0025] Please refer to Figure 1 , Figure 2 and Figure 4The rosin production filtration device includes a filter barrel 100 and a cover 200 detachably connected to the filter barrel 100. The cover 200, after being installed on the filter barrel 100, closes the opening of the filter barrel 100. The filter barrel 100 is provided with a discharge pipe 101. A rotatable rotating seat 300 is provided inside the filter barrel 100, and a drive motor 400, which is pulsatorically connected to the rotating seat 300, is provided on the filter barrel 100. A detachable filter cartridge 500 is provided on the filter barrel 100. The cover 200 covers the opening at the top of the filter barrel 100, and a feed pipe 201, communicating with the filter cartridge 500, is provided on the cover 200. Material is fed into the filter cartridge 500 along the feed pipe 201, and the drive motor 400 drives the rotating seat 300 to rotate, which in turn drives the filter cartridge 500 to rotate, thus accelerating the passage of material through the filter cartridge 500. The filter cylinder 500 has a mesh that filters the material. The cover 200 is also provided with a first scraper 202 that can move radially along the cover 200 and a first spring 203 that abuts against the first scraper 202. The first scraper 202 extends into the filter cylinder 500. The first spring 203 drives the first scraper 202 to abut against the inner wall of the filter cylinder 500. The cover 200 is also provided with a second scraper 204 that can move radially along the cover 200 and a second spring 205 that abuts against the second scraper 204. The second scraper 204 is located between the filter barrel 100 and the filter cylinder 500. The second spring 205 drives the second scraper 204 to abut against the outer wall of the filter cylinder 500. During the rotation of the filter cylinder 500, the first scraper 202 and the second scraper 204 scrape the inner and outer walls of the filter cylinder 500, respectively.
[0026] Specifically, the operation steps for filtering rosin using the rosin production filtration device provided in this embodiment are as follows: the material to be filtered is injected into the filter cylinder 500 along the feed pipe 201; the drive motor 400 is started to drive the rotating seat 300 to rotate and drive the filter cylinder 500 to rotate; when the filter cylinder 500 rotates, the material in the filter cylinder 500 is thrown out of the filter cylinder 500 and passes through the mesh on the filter cylinder 500 to filter the material; the filtered material enters between the filter cylinder 500 and the filter barrel 100 and is discharged from the discharge pipe 101, while the impurities in the material remain in the filter cylinder 500, thus completing the material filtration operation. Furthermore, during the operation of the rosin production filtration device, the first scraper 202 on the cover plate extends into the filter cylinder 500, and the second scraper 204 extends between the filter cylinder 500 and the filter barrel 100. The first scraper 202, driven by the first spring 203, abuts against the inner wall of the filter cylinder 500, and the second scraper 204, driven by the second spring 205, abuts against the outer wall of the filter cylinder 500. During the rotation of the filter cylinder 500, the first scraper 202 can scrape off the impurities attached to the inner wall of the filter cylinder 500, while the second scraper 204 scrapes off the material retained on the outer wall of the filter cylinder 500, thereby preventing impurities or retained material from clogging the filter cylinder 500. The rosin production filtration device provided in this embodiment automatically cleans the inner and outer walls of the filter cylinder 500 during its rotation by setting the first scraper 202 and the second scraper 204, thereby extending the service life of the rosin production filtration device and reducing the maintenance frequency, thus reducing the number of maintenance operations and improving filtration efficiency.
[0027] like Figure 2 As shown, the rotating base 300 has a mounting shaft 301, and the filter barrel 100 is provided with a mounting hole that mates with the mounting shaft 301. One end of the mounting shaft 301 passes through the mounting hole and mates with the output end of the drive motor 400. The mounting shaft 301 is positioned on the mounting base to mate with the output end of the drive motor 400, so that the mounting base can rotate smoothly under the drive of the drive motor 400.
[0028] Please combine Figure 5 and Figure 6The rotating seat 300 has a slot 302 and a through hole 303 communicating with the slot 302. The bottom of the filter cartridge 500 has a mounting part 501 and the mounting part 501 is provided with a locking block 502 that cooperates with the slot 302. The through hole 303 allows the locking block 502 to enter and exit the slot 302. When installing the filter cartridge 500 onto the rotating base 300, first pass the locking block 502 through the through hole 303, then rotate the filter cartridge 500 so that the locking block 502 is engaged in the slot 302, thus fixing the filter cartridge 500 onto the rotating base 300. This ensures a reliable fit between the filter cartridge 500 and the rotating base 300. After the filter cartridge 500 is installed onto the rotating base 300, the mounting part 501 closes the through hole 303 and the slot 302, preventing material from entering the through hole 303 or the slot 302. When it is necessary to remove the filter cartridge 500 from the rotating base 300 for cleaning, first rotate the filter cartridge 500 so that the locking block 502 exits the slot 302 and aligns with the through hole 303, then pull the locking block 502 out of the through hole 303. The operation is simple and disassembly is convenient.
[0029] like Figure 2 and Figure 4 As shown, the cover 200 has a positioning hole 206 on the side near the filter barrel 100, and the feed pipe 201 communicates with the positioning hole 206. The top of the filter cylinder 500 extends into the positioning hole 206 and fits against the cover 200. With the positioning hole 206 on the cover 200, after the cover 200 is installed on the filter barrel 100, the top of the filter cylinder 500 engages with the positioning hole 206, thereby sealing the top of the filter cylinder 500 through the cover 200. This prevents material from being thrown out from the top of the filter cylinder 500 during rotation, thus avoiding some unfiltered material from mixing into the filtered material and ensuring the filtration effect of the rosin production filtration device.
[0030] Please refer to Figure 3 and Figure 4The cover 200 is provided with a guide groove 207, the length direction of which is consistent with the radial direction of the cover 200. The first scraper 202 and the second scraper 204 each have a slider 208 that cooperates with the guide groove 207. The guide groove 207 on the cover 200 guides the first scraper 202 and the second scraper 204 to move on the cover 200. The sliders 208 on the first scraper 202 and the second scraper 204 cooperate with the guide groove 207 to prevent unexpected deviations during movement and to ensure that the first scraper 202 and the second scraper 204 remain in contact with the surface of the filter cartridge 500 during rotation.
[0031] In detail, the cover 200 is provided with a guide rod 209 that extends into the guide groove 207. The slider 208 is provided with guide holes that cooperate with the guide rod 209. The first spring 203 and the second spring 205 are respectively sleeved on the guide rod 209. By setting the guide rod 209 in the guide groove 207 and cooperating with the guide holes on the slider 208, the slider 208 is kept in the guide groove 207, preventing the first scraper 202 and / or the second scraper 204 from falling out of the groove. The first spring 203 and the second spring 205 are respectively sleeved on the guide rod 209, so that the first spring 203 is kept in contact with the first scraper 202 and the second spring 205 is kept in contact with the second scraper 204, thereby improving the structural stability of the rosin production filter device.
[0032] like Figure 4 As shown, the first scraper 202 is L-shaped, and it abuts against the side and bottom surfaces of the inner wall of the filter cartridge 500. By setting the first scraper 202 to an L-shape, it can scrape away impurities adhering to the side and bottom surfaces of the inner wall of the filter cartridge 500 during rotation, thereby preventing clogging of the mesh openings on the side and bottom surfaces of the filter cartridge 500 and improving the cleaning effect of the first scraper 202.
[0033] Please combine Figure 1 , Figure 3 and Figure 4The top of the filter barrel 100 is provided with a locking seat 102. The locking seat 102 is provided with a rotatable locking screw 103 and a locking knob 104 that cooperates with the locking screw 103. The cover 200 is provided with a locking plate 210 and the locking plate 210 has a slot 211 for accommodating the locking screw 103. The locking knob 104 abuts against the side of the locking plate 210 away from the locking seat 102 and presses the cover 200 onto the filter barrel 100. After the cover plate is placed on the filter barrel 100, rotate the locking screw 103 to make the locking screw 103 enter the slot 211, and then rotate the locking knob 104 to make the locking knob 104 abut against the locking plate 210 to fix the position of the cover plate on the filter barrel 100 and ensure that the cover plate seals the filter barrel 100. When it is necessary to remove the cover plate to clean the inside of the filter barrel 100, rotate the locking knob 104 to move the locking knob 104 away from the locking plate 210, and then rotate the locking screw 103 to make the locking screw 103 exit the slot 211, so that the cover plate can be removed from the filter barrel 100. The operation is simple and convenient.
[0034] like Figure 2 As shown, the filter barrel 100 has a jacket 105, and the filter barrel 100 is also provided with an inlet pipe 106 and an outlet pipe 107, and the inlet pipe 106 and the outlet pipe 107 are respectively connected to the jacket 105. By injecting a heat-conducting medium into the inlet pipe 106 connected to the jacket 105 and discharging it through the outlet pipe 107, the heat-conducting medium circulates within the jacket 105, which can heat the material in the filter barrel 100, so that the material in the filter barrel 100 remains fluid, preventing the material from solidifying after cooling, and ensuring the stable operation of the rosin production filtration device.
