[0033] Further, the cleaning mechanism 200 comprises a scraper assembly 210, a flushing assembly 220, a rolling brush assembly 230 and a receiving hopper 240, one end of the scraper assembly 210 is fixed to the rack 110, the other end of the scraper assembly 210 elastically abuts against the bottom of the lower end surface of the conveying belt 150, the scraper assembly 210 is used for removing the residual slurry on the surface of the conveying belt 150, the receiving hopper 240 is fixed to the rack 110, the receiving hopper 240 is arranged below the scraper assembly 210, the receiving hopper 240 is used for receiving the falling slurry, the flushing assembly 220 is arranged at the bottom of the conveying belt 150, the flushing assembly 220 is used for flushing the surface of the conveying belt 150, the rolling brush assembly 230 is arranged in the water washing tank 301, the rolling brush assembly 230 abuts against the conveying belt 150, the rolling brush assembly 230 is used for brushing the surface of the conveying belt 150.

[0034] In this embodiment, clean water is first injected into the water washing tank 301, so that the liquid surface of the clean water submerges the rolling brush assembly 230, the conveying main roller 120 drives the movement of the conveying belt 150, when the conveying belt 150 passes through the scraper assembly 210, the scraper assembly 210 scrapes off the slurry adhered to the surface of the conveying belt 150, so that the scraped slurry falls into the receiving hopper 240; the conveying main roller 120 drives the movement of the conveying belt 150 to above the flushing assembly 220, the flushing assembly 220 flushes the surface of the conveying belt 150, so that the residual slurry on the conveying belt 150 is removed by flushing; the conveying main roller 120 drives the movement of the flushed conveying belt 150 into the water washing tank 301, the rolling brush assembly 230 brushes the conveying belt 150, so that the slurry on the conveying belt 150 is fully cleaned.

[0035] The NMP slurry conveying and cleaning device 10 described above, when the conveying belt 150 passes through the scraper assembly 210, the scraper assembly 210 scrapes off the slurry adhered on the conveying belt 150, and the scraped slurry is collected through the lower material receiving hopper 240, thereby avoiding the problems of material accumulation and blockage caused by the slurry falling from the conveying belt 150, and facilitating the recycling of the scraped slurry; the conveying belt 150 is washed through the washing assembly 220, the conveying belt 150 is diverted into the water washing tank 301 through the diverting roller 140, the conveying belt 150 is brushed and washed by the rolling brush assembly 230 in the water washing tank 301, so that the conveying belt 150 is fully cleaned, efficient cleaning of the conveying belt 150 during operation is realized, and the maintenance time is saved, thereby improving the production efficiency.

[0036] As shown in the drawings, Figure 2 In one embodiment, the scraper assembly 210 includes a scraper frame 211, an abutting piece 212, an elastic member 213, and a scraping plate 214. The scraper frame 211 is connected to the rack 110, and is provided with a movable groove 2101. The abutting piece 212 is connected to the elastic member 213, and the elastic member 213 and the abutting piece 212 are installed in the movable groove 2101. Part of the scraping plate 214 is movably arranged in the movable groove 2101, the abutting piece 212 abuts against the scraping plate 214, and the scraping plate 214 elastically abuts against the bottom of the lower end surface of the conveying belt 150. In this embodiment, the scraping plate 214 is made of polyurethane, which has good wear resistance. The contact surface of the scraping plate 214 is flat, the elastic member 213 and the abutting piece 212 elastically abut against the scraping plate 214, and the scraping plate 214 elastically abuts against the bottom of the lower end surface of the conveying belt 150. Therefore, the elastic member 213 can absorb the vibration generated when the scraping plate 214 scrapes off the slurry, and automatically compensate for the wear of the scraping plate 214, so that the scraping plate 214 maintains good contact with the conveying belt 150, and the scraping plate 214 maintains good scraping effect on the bottom of the lower end surface of the conveying belt 150.

[0037] As shown in the drawings, Figure 2 In one embodiment, the scraper assembly 210 further includes a threaded limiting member. The number of threaded limiting members 215 is multiple, and the two side walls of the scraper frame 211 are respectively provided with a plurality of threaded holes 2102. Each threaded limiting member 215 is arranged in the corresponding threaded hole 2102. In this embodiment, the threaded limiting members 215 of the two side walls of the scraper frame 211 are used to limit the position of the scraping plate 214, so that the threaded limiting members 215 can adjust the horizontal position of the scraping plate 214 in the movable groove 2101. The threaded limiting members 215 control the scraping plate 214 to abut against the conveying belt 150, so that the scraping plate 214 maintains pressure on the conveying belt 150, thereby maintaining the stable scraping effect of the scraping plate 214 on the conveying belt 150.

[0038] As shown in the drawings,Figure 1 and Figure 3 As shown, in one embodiment, the flushing assembly 220 includes a Laval nozzle 221 and a flushing pipe 222. The flushing pipe 222 is disposed at the bottom of the conveyor belt 150 and is horizontally arranged in the width direction of the conveyor belt 150. Multiple Laval nozzles 221 are present, each connected to a flow channel within the flushing pipe 222. These multiple Laval nozzles 221 are spaced apart along the length direction of the flushing pipe 222. In this embodiment, the Laval nozzle 221 mainly consists of a constriction section, a throat, and an expansion section. The constriction section is conical or curved and gradually contracts inward, causing the high-pressure liquid to gradually increase in velocity and decrease in pressure as it flows through the constriction section, simultaneously converting the liquid's pressure energy into kinetic energy. The throat is the junction with the smallest cross-sectional area between the constriction and expansion sections, where the liquid velocity reaches the speed of sound. The expansion section is located after the throat, and is conical or curved and gradually expands outward, further increasing the liquid velocity and allowing the liquid to obtain maximum kinetic energy when it exits the nozzle. The system features a flushing pipe 222 connected to a water pump. The water pump delivers liquid into the flow channel within the flushing pipe 222, and the liquid then enters the Laval nozzle 221 from the flow channel of the flushing pipe 222. The special structure of the Laval nozzle 221 causes the liquid flow rate to change due to the change in the spray cross-sectional area, thereby increasing the flow rate of the spray water formed by the liquid spraying out of the Laval nozzle 221. This results in a better cleaning effect of the spray water on the conveyor belt 150. By flushing the conveyor belt 150 with multiple Laval nozzles 221, the cleaning effect of the conveyor belt 150 is improved.

[0039] like Figure 3 As shown, in one embodiment, the Laval nozzle 221 is tilted at an angle of 25°-35° relative to the direction of movement of the conveyor belt 150. In this embodiment, A in the figure represents the tilt angle between the Laval nozzle 221 and the direction of movement of the conveyor belt 150. The direction of the spray water from the Laval nozzle 221 is consistent with the direction of movement of the conveyor belt 150, making the impact of the spray water from the Laval nozzle 221 on the conveyor belt 150 more gentle, reducing the impact damage to the conveyor belt 150, and thus extending the service life of the conveyor belt 150.

[0040] like Figure 5 As shown, in one embodiment, the roller brush assembly 230 includes an electric roller brush 231 and an adjusting bracket 232. The adjusting bracket 232 is disposed within the washing tank 301, and the electric roller brush 231 is rotatably mounted on the adjusting bracket 232, abutting against the surface of the conveyor belt 150. In this embodiment, the adjusting bracket 232 can adjust the electric roller brush 231 to be closer to the conveyor belt 150, so that the electric roller brush 231 makes full contact with the conveyor belt 150, thereby improving the cleaning effect of the electric roller brush 231 on the conveyor belt 150.

[0041] As shown in Figure 5 one of the embodiments, the adjusting support 232 comprises a support base 2321, a first rod 2322 and a second rod 2323. The support base 2321 is provided with a strip-shaped hole 2301. One end of the first rod 2322 is hingedly connected to the support base 2321. The motorized roller brush 231 is rotatably connected to the other end of the first rod 2322. The first end of the second rod 2323 is hingedly connected to the middle part of the first rod 2322. The second end of the second rod 2323 is provided with a threaded connection part 2323a, which is rotatably connected to the support base 2321 and slidably connected to the support base 2321. The threaded connection part 2323a is provided in the strip-shaped hole 2301. In this embodiment, when the motorized roller brush 231 is adjusted to contact the conveying belt 150, the second end of the second rod 2323 is slid and rotated in the strip-shaped hole 2301 by a corresponding angle, so that the position of the first rod 2322 hingedly connected to the first end of the second rod 2323 is changed, thereby controlling the position of the motorized roller brush 231 on the first rod 2322, adjusting the pressure of the motorized roller brush 231 on the conveying belt 150, and further making the cleaning effect of the motorized roller brush 231 on the conveying belt 150 better.

[0042] As shown in Figure 6 one of the embodiments, the adjusting support 232 further comprises a locking nut 2324. The second end of the second rod 2323 is provided with the threaded connection part 2323a, which is rotatably connected to the support base 2321 and slidably connected to the support base 2321. The threaded connection part 2323a is provided in the strip-shaped hole 2301. The locking nut 2324 is threadedly connected to the threaded connection part 2323a. In this embodiment, when the motorized roller brush 231 is adjusted to contact the conveying belt 150, the threaded connection part 2323a is slid and rotated in the strip-shaped hole 2301 by a corresponding angle, so that the position of the first rod 2322 hingedly connected to the first end of the second rod 2323 is changed, thereby controlling the position of the motorized roller brush 231 on the first rod 2322, adjusting the pressure of the motorized roller brush 231 on the conveying belt 150, and further making the cleaning effect of the motorized roller brush 231 on the conveying belt 150 better. When the locking nut 2324 is tightened with the threaded connection part 2323a, the locking nut 2324 locks the position of the threaded connection part 2323a in the strip-shaped hole 2301. When the locking nut 2324 is loosened with the threaded connection part 2323a, the threaded connection part 2323a can be freely slid in the strip-shaped hole 2301, so that the second rod 2323 can adjust the position of the connected first rod 2322, thereby flexibly adjusting and fixing the position of the motorized roller brush 231 on the first rod 2322.

[0043] As shown in Figure 1 and Figure 5As shown in the figure, in one embodiment, the electric roller brush 231 is also connected to a driving motor, which is used to control the rotation of the electric roller brush 231, and the tangent direction of the rotation of the electric roller brush 231 is opposite to the direction of the movement of the conveying belt 150. In this embodiment, when the tangent direction of the rotation of the electric roller brush 231 is opposite to the direction of the movement of the conveying belt 150, the relative movement between the electric roller brush 231 and the conveying belt 150 is more intense, so that the electric roller brush 231 can effectively brush the dirt and residues on the conveying belt 150, thereby improving the cleaning effect of the electric roller brush 231 on the conveying belt 150.

[0044] As shown in the figure, Figure 5 In one embodiment, the water tank structure 300 includes a tank body 310 and a pulley 320, the tank body 310 is provided with a washing tank 301, and the pulley 320 is arranged at the bottom of the tank body 310.

[0045] As shown in the figure, Figure 5 In one embodiment, the bottom of the washing tank 301 is also formed with an inclined surface 311, the side wall of the tank body 310 is provided with a residue discharge port 3101, and the inclined surface 311 extends to the end of the residue discharge port 3101 located in the tank body 310. In this embodiment, the waste water and residues in the washing tank 301 are discharged through the residue discharge port 3101, and the inclined surface 311 can guide the flow direction of the waste water and residues to the residue discharge port 3101, which facilitates the flow of the waste water and residues from the inclined surface 311 to the residue discharge port 3101 and discharges, so that the cleaning effect of the washing tank 301 is better.

[0046] As shown in the figure, Figure 5 In one embodiment, the side wall of the tank body 310 is provided with an overflow hole 3102, and the overflow hole 3102 is communicated with the washing tank 301. In this embodiment, the overflow hole 3102 is communicated with a sedimentation tank, when the liquid level in the washing tank 301 exceeds the overflow hole 3102, the excess water is discharged into the sedimentation tank, which prevents the liquid from overflowing out of the tank body 310, and the flushing assembly 220 can extract the supernatant of the sedimentation tank to flush the conveying belt 150, thereby realizing the reuse of waste water.
