Description

Technical Field

[0001] The invention relates to a waste residue cleaning device, in particular to a scale cleaning module for a residue discharge port. Background Art

[0002] During the processing of the circuit board, it needs to go through the steps of exposure and development to print the circuit on the circuit board. Then, in the subsequent etching process, the copper layer of the non-circuit part is corroded, and the circuit part that needs to be retained is covered with a film. After the etching is completed, the film needs to be removed and cleaned. After the film is removed from the circuit board, it will be mixed together. The cleaning liquid is reused using a circulating liquid supply system. However, since the film removed from the circuit board and the cleaning liquid are mixed together, the film in the cleaning liquid needs to be separated before recycling. The separated waste residue will be discharged from the slag discharge port. Since the separated film still contains water, it is easy to hang on the slag discharge port when discharged, and these waste residues will condense and stick to the slag discharge port after drying. As time accumulates, it will eventually cause the slag discharge port to be blocked. Summary of the invention

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Embodiment 1: The present invention specifically discloses a dirt cleaning module for a slag discharge port, such as Figure 1-Figure 5 As shown, it includes: a slag discharge pipe 11 for receiving waste slag. When in use, the slag discharge pipe 11 needs to be installed at the slag outlet of the separation equipment. The waste slag enters the slag discharge pipe 11 from the separation equipment. A rotating shaft 12 is installed and rotated in the slag discharge pipe 11. A spiral plate 13 is provided on the rotating shaft 12 and is placed in the slag discharge pipe 11 for rotation. After the waste slag enters the slag discharge pipe 11, it moves in the slag discharge pipe 11 with the rotation of the spiral plate 13. The driving of the rotating shaft 12 can be achieved by connecting a motor.

[0031] The end of the slag discharge pipe 11 is provided with a blocking cover 14 through a connector, and a protective cover 151 is provided on the blocking cover 14. A narrow extrusion gap 17 is left between the blocking cover 14 and the slag discharge pipe 11 for the waste slag to flow out. After the waste slag is pushed to the end of the slag discharge pipe 11 by the spiral plate 13, it will contact the blocking cover 14, and under the continuous rotation of the spiral plate 13, the waste slag is squeezed and pushed to flow out of the extrusion gap 17. The turntable 15 is rotatably arranged at the end of the blocking cover 14 and is connected to the rotating shaft 1 2 is connected to rotate with the rotating shaft 12, and the rotating disk 15 is rotated and placed between the protective cover 151 and the blocking cover 14, so that after the rotating shaft 12 rotates, the rotating disk 15 can rotate with the rotating shaft 12, and the scraper 16 is fixedly installed on the outer wall of the rotating disk 15. A plurality of scrapers 16 can be provided. The scraper 16 extends across the extrusion gap 17 and fits on the surface of the slag discharge pipe 11. The scraper 16 scrapes the waste slag overflowing from the extrusion gap 17 during the rotation of the rotating disk 15.

[0032] Specifically, when in use, when the waste slag moves from the slag discharge pipe 11 toward the outlet, it will be squeezed and overflow from the extrusion gap 17. The waste slag coming out in this way is scattered and is not easy to accumulate into lumps after falling, which is more convenient in subsequent processing. During the rotation of the rotating shaft 12, the turntable 15 will rotate together, and the scraper 16 installed on the turntable 15 will scrape off the waste slag adhered to the extrusion gap 17, so as to keep the extrusion gap 17 clean, avoid blockage, and achieve a self-cleaning effect at the outlet.

[0033] like Figure 1 and Figure 3As shown, the adjacent end edges of the blocking cover 14 and the slag discharge pipe 11 are beveled chamfers 171, and the blocking cover 14 and the slag discharge pipe 11 are close to each other to form an inclined extrusion gap 17 through the beveled chamfers 171. The original angle of the extrusion gap 17 is perpendicular to the axis of the slag discharge pipe 11, so that when the waste slag is extruded, it needs to make a right-angle turn to be discharged from the slag discharge pipe 11, so that part of the waste slag is left at the right-angle bend of the slag discharge pipe 11. The inclined extrusion gap 17 can make the path of the waste slag out of the slag discharge pipe 11 inclined, so that the waste slag is not easily stuck in the extrusion gap 17.

[0034] like Figure 3 As shown, the connecting member includes: a plurality of fixing bolts 141, which are installed at the end of the slag discharge pipe 11, and the blocking cover 14 is installed at the end of the slag discharge pipe 11 through the fixing bolts 141. In this way, the blocking cover 14 is fixedly installed at the end of the slag discharge pipe 11.

[0035] like Figure 4 As shown, the extended portion of the scraper 16 is an arc curved portion 161, and the arc curved portion 161 is attached to the outer surface of the slag discharge pipe 11. Figure 5 As shown, the extended portion of the scraper 16 can also be designed as a straight inclined extension portion 162, and the inclined extension portion 162 is attached to the outer surface of the slag discharge pipe 11. When in use, the scraped slag can flow along the arc curve through the shape of the arc curved portion 161 or the inclined extension portion 162, so that the slag can be better discharged to the end of the scraper 16.

[0036] In order to prevent the scraper 16 from easily causing the waste residue to adhere and accumulate on the scraper 16 when scraping the waste residue, the scraper 16 is installed on the turntable 15 at an angle of 45 degrees. Only the end of the scraper 16 after the inclination contacts the waste residue, so that the scraper 16 is not prone to the situation of waste residue adhesion.

[0037] like Figure 3As shown, the rotary disk 15 also includes a deceleration mechanism, which is additionally provided between the rotating shaft 12 and the rotating disk 15, and the rotating disk 15 is connected to the rotating shaft 12 through the deceleration mechanism. The deceleration mechanism includes: three fixing pins 21 are fixedly installed on the blocking cover 14, and the fixing pins 21 are rotatably connected to the planetary gears 23, and the sun gear 24 is connected to the rotating shaft 12 through a key, and the sun gear 24 is placed in the middle of the three planetary gears 23, and the sun gear 24 is meshed with the planetary gears 23, and the outer layer of the three planetary gears 23 is provided with an outer gear ring 22, and the outer gear ring 22 is meshed with the planetary gears 23, and the rotating disk 15 is installed on the outer gear ring 22. After the rotating shaft 12 rotates with the sun gear 24, the planetary gears 23 are driven to rotate, and finally the outer gear ring 22 is driven by the planetary gear 23 to rotate with the rotating disk 15, and after the speed of the rotating shaft 12 is decelerated, the rotating disk 15 is finally rotated slowly, and the slowly rotating rotating disk 15 has a larger torque, which can make the scraper 16 have a greater force when scraping the adhered waste residue.

[0038] Embodiment 2: Based on embodiment 1, Figure 6-Figure 10 As shown, the connecting member includes: a hoop 31 fixedly mounted on the slag discharge pipe 11, connecting posts 32 fixedly mounted on both sides of the hoop 31, and a protective cover 151 connected to the connecting posts 32. Compared with embodiment 1, the blocking cover 14 and the slag discharge pipe 11 of this embodiment are not connected by the fixing bolt 141, so that there is no obstruction in the extrusion gap 17, and the waste slag will not be blocked and stuck by the fixing bolt 141.

[0039] like Fig. 9 and Fig.10 As shown, the scraper 16 is also provided with a gap cleaning tooth 41, which is embedded in the extrusion gap 17. During the rotation of the scraper 16, the gap cleaning tooth 41 can extend into the extrusion gap 17, so that the waste residue in the extrusion gap 17 can be cleaned out to prevent the waste residue from getting stuck in the extrusion gap 17.

[0040] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
