[0021] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. Furthermore, unless otherwise defined, the technical or scientific terms used in the description of this invention should have the ordinary meaning understood by those skilled in the art.

[0022] like Figure 1 As shown, a solid waste recycling device for ceramic tile manufacturing process is used for the recycling and treatment of solid waste (such as waste ceramic tiles, waste minerals, etc.) generated during ceramic tile manufacturing. It includes a crushing device, a screening device, a grinding device, a cyclone separator, and a pulse bag separator. The downstream of the crushing device is connected to the screening device via a first conveyor. The fine particles screened out by the screening device are connected to the grinding device via a second conveyor. The coarse particles / large pieces screened out are further processed according to their intended use (such as manufacturing industrial bricks, garden bricks, sand making, etc.). The downstream of the grinding device is connected to the cyclone separator. The fine particles separated by the cyclone separator are further processed according to their intended use (such as manufacturing industrial bricks, garden bricks, sand making, etc.). The downstream of the cyclone separator is connected to the pulse bag separator.

[0023] like Figure 2-4 As shown, the pulse bag separator includes a filter cartridge, a cleaning nozzle, and a blower. The cleaning nozzle includes a first cylinder 1, a second cylinder 2, an inner cylinder 3, and a nozzle head 4. The right end of the first cylinder 1 is connected to the left end of the second cylinder 2. The inner cylinder 3 is installed inside the second cylinder 2. The left end of the first cylinder 1 is connected to the nozzle head 4. The first cylinder 1 includes a right cylinder section 11 and a left cylinder section 12. The right cylinder section 11 is connected to the left end of the second cylinder 2 by a thread. The left cylinder section 12 has a first cavity 13. The inner circumferential wall of the first cavity 13 has protrusions 14. Multiple protrusions 14 are evenly distributed circumferentially. The distance between two adjacent protrusions 14 is... The first cavity airflow channel is formed by the two cylinders; the second cylinder 2 has a second cavity 22 inside, and an air inlet 21 is opened at the right end of the second cylinder 2. The air inlet 21 is connected to / communicates with a compressed air source. An annular groove 23 is opened on the inner circumferential wall at the left end of the second cavity 22; the inner cylinder 3 is installed in the second cavity 22. An axial channel 31 is opened at the right end of the inner cylinder 3, and a radial channel 32 is opened at the left end. Multiple radial channels 32 are evenly distributed along the circumference, and no airflow hole is opened on the left end face of the inner cylinder 3. The left end face of the inner cylinder 3 is flush with the left end face of the annular groove 23; the annular groove 23 and the first cavity airflow channel have a common communication channel 15.

[0024] The compressed air flow path is as follows: air inlet 21 → axial channel 31 → radial channel 32 → annular groove 23 → common connecting channel 15 → first cavity airflow channel → first cavity 13 → nozzle head 4 injection hole 43.

[0025] The protrusion 14 is elongated and its cross-section is fan-shaped, such as... Figure 4 As shown.

[0026] The centerline of the protrusion 14 is inclined or spirally arranged relative to the central axis of the cleaning nozzle.

[0027] This invention improves the spray performance (such as spray force and / or spray speed) of the cleaning nozzle of the pulse bag separator by structural design, compared with existing cleaning nozzles, under the same pressure. This improves the cleaning efficiency of the cleaning nozzle on the filter cartridge and the separation efficiency of the pulse bag separator.

[0028] In one embodiment, the nozzle head 4 includes a left nozzle head section 41 and a right nozzle head section 42. The left nozzle head section 41 has a spray hole 43, and the right nozzle head section 42 has a nozzle through hole. A ring body 44 is connected to the outer peripheral surface of the right end of the right nozzle head section 42. A helical spring 46 is sleeved on the outer periphery of the right nozzle head section 42. One end of the helical spring 46 is connected to the side of the ring body 44, and the other end is connected to the inner side of the left end of the left cylinder section 12. The right nozzle head section 42 extends into the first cavity 13 and is slidably connected to the inner hole of the left end of the left cylinder section 12. Under different supplied compressed air pressures, the ring body 44 is subjected to force and can move axially so that the ring body 44 can be located at different positions in the first cavity 13.

[0029] A limiting surface is provided at the right end of the left nozzle head section 41. This limiting surface has a distance S between it and the left end face of the left cylinder section 12. Under different supplied compressed air pressures, the ring body 44 can be moved axially, allowing it to be located at different positions within the first cavity 13, thus making the distance S variable. Figure 3-4 As shown.

[0030] The present invention, through the structural design of the nozzle head 4, allows the ring body 44 to move axially under different supplied compressed air pressures, so that the ring body 44 can be located at different positions within the first cavity 13, making the spacing S variable. This allows for adjustment of the axial length of the cleaning nozzle and the spray performance (such as spray force and / or spray speed) of the cleaning nozzle, thereby improving the cleaning efficiency of the cleaning nozzle on the filter cartridge and improving the separation efficiency of the pulse bag separator.

[0031] Furthermore, a gap g exists between the left end face of the protrusion 14 and the inner end face of the left end of the left cylinder section 12. A connecting hole 45 is provided at the right end of the right nozzle head section 42. Multiple connecting holes 45 are evenly distributed circumferentially, and the connecting holes 45 are located adjacent to the ring body 44. The upstream end of the connecting hole 45 is located closer to the ring body 44 than the downstream end. Through the connection hole 45, the airflow on the outer circumference of the right nozzle head section 42 can flow into the nozzle through hole through the connecting hole 45, which can further adjust the spray performance of the cleaning nozzle.

[0032] Optionally, the injection hole 43 and / or the nozzle through hole are provided with spiral grooves, and multiple spiral grooves are evenly distributed circumferentially.

[0033] Furthermore, the first cavity 13 has a diameter d1, the protrusion 14 has an inner diameter d2, the inner cylinder 3 has an outer diameter d3, and the annular groove 23 has a diameter d4, where d2 < d3 < d1 < d4.

[0034] Diameter d2=(0.6-0.75)d4, d3=(0.75-0.85)d4, d1=(0.85-0.95)d4.

[0035] This invention, through the optimized design of parameters d1, d2, d3, and d4, can further improve the spraying performance (such as spraying force and / or spraying speed) of the cleaning nozzle.

[0036] The present invention discloses a solid waste recycling device for ceramic tile manufacturing process. Through the structural design of the cleaning nozzle of the pulse bag separator, the device can improve the spraying performance of the cleaning nozzle compared with existing cleaning nozzles, adjust the axial length of the cleaning nozzle, and adjust the spraying performance (such as spraying force and / or spraying speed) of the cleaning nozzle, thereby improving the cleaning efficiency of the cleaning nozzle on the filter cartridge and improving the separation efficiency of the pulse bag separator.

[0037] The above embodiments are illustrative of the present invention and not intended to limit the invention. It is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
