Description

Technical Field

[0001] The invention relates to the technical field of scrap copper recovery, and in particular to an environmentally friendly scrap copper smelting system. Background Art

[0002] The environmentally friendly smelting system for scrap copper is a device or process specifically used to process and recycle scrap copper materials, aiming to convert scrap copper into reusable copper raw materials in an environmentally friendly way. The application of this system helps to reduce resource waste, reduce environmental pollution, and improve economic benefits. In the process of recycling and smelting scrap copper, a large amount of flue gas containing harmful substances will inevitably be generated. In order to protect the environment and meet increasingly stringent environmental standards, these flue gases must be effectively purified. Among the traditional flue gas purification methods, bag dust collectors are widely used due to their efficient dust capture ability. However, in actual operation, due to the high concentration of fine particles in the flue gas of scrap copper smelting, conventional bag dust collection systems face the problem of easy clogging of bags, which not only reduces the dust collection efficiency, but also increases maintenance costs.

[0003] In order to solve this problem, the present invention proposes an environmentally friendly smelting system for scrap copper. This smelting system adopts the design concept of three groups of bag filter structures. By dividing the bag filter structure into three independent working units, the regular replacement and cleaning of the bags can be achieved without affecting the overall dust collection effect. The advantage of this is that when a group of bag filter structures has been used for a certain period of time, it automatically switches to the next group to continue working, while the previous group starts the dust cleaning operation. This rotating working mode effectively avoids system shutdowns caused by bag blockage, while also reducing the frequency of manual intervention and improving the continuity and stability of the entire smelting process. Summary of the invention

[0004] In order to overcome the problem that bag-type dust collectors are prone to clogging after being used for a certain period of time, and need to be shut down for cleaning, which not only reduces the dust collection efficiency but also increases the maintenance cost, the technical problem of the present invention is to provide an environmentally friendly smelting system for scrap copper.

A first gear 16 is fixedly connected to the left part of the rotating shaft 8. A reduction motor 17 is fixedly connected to the left side of the processing box 6. A toothed ring 18 is fixedly connected to the output shaft of the reduction motor 17, and the toothed ring 18 rotates to engage with the first gear 16. An extrusion component for squeezing the cloth bag 11 to retract is provided on the processing box 6 and the partition 9, and a knocking component is provided on the processing box 6 and the rotating shaft 8. The knocking component is used to knock on the processing box 6 to shake off the dust on the inner wall.

[0033] When the device is used, the flue gas generated by smelting scrap copper in the smelting furnace 1 enters the absorption tower 3, and harmful chemicals are absorbed by the absorption tower 3. The purified flue gas enters the hollow cylinder 5 through the gas transmission pipe 4, and is then introduced into a front space in the treatment box 6 through the fixed cylinder 51 and the connecting pipe 7. The flue gas in the treatment box 6 is filtered by the cloth bag 11, and then transported to the right from the inside of the cloth bag 11 and discharged through the air outlet pipe. During the use of this device, the staff controls the operation of the reduction motor 17, and the output shaft of the reduction motor 17 rotates to drive the missing gear ring 18 to rotate. When the missing gear ring 18 rotates to mesh with the first gear 16, the missing gear ring 18 continues to rotate, which will drive the first gear 16 to rotate counterclockwise. The counterclockwise rotation of the first gear 16 drives the rotating shaft 8 to rotate counterclockwise. The counterclockwise rotation of the rotating shaft 8 drives the partition 9 to rotate counterclockwise. The counterclockwise rotation of the partition 9 drives the fixed ring 10, the cloth bag 11, the guide rail 12, the slider 13 and the moving The ring 15 rotates counterclockwise together to switch the next group of filtering structures. The fixed ring 10 will block the exhaust pipe when it revolves counterclockwise to prevent unfiltered smoke from being discharged. When the partition 9 rotates counterclockwise to switch the cloth bag 11, the extrusion assembly can squeeze the cloth bag 11 to retract, and the left end of the cloth bag 11 moves to the right, and then the slider 13 slides to the right through the moving ring 15, and the first spring 14 is deformed. When the extrusion assembly releases the cloth bag 11, under the action of the first spring 14 resetting, the slider 13 drives the moving ring 15 to move to the left and reset, and then the moving ring 15 and the fixed ring 10 cooperate to pull the cloth bag 11, and then the dust attached to the surface of the cloth bag 11 is shaken off to prevent the cloth bag 11 from being blocked and affecting subsequent use. The dust pulled off can be discharged through the dust discharge port on the lower side of the treatment box 6. While the rotating shaft 8 rotates, the knocking assembly can knock on the treatment box 6 to shake off the dust on the inner wall of the treatment box 6.

[0034] like Figure 6 and Figure 7 As shown, the extrusion assembly includes a convex plate 181, a mounting frame 19, an extrusion plate 20, a first torsion spring 201 and a second gear 21. The convex plates 181 are fixedly connected to the smelting furnace 1 with equal spacing. The left and right mounting frames 19 are fixedly connected between two adjacent partitions 9. The extrusion plate 20 is rotatably connected to the mounting frame 19. The extrusion plate 20 on the right side revolves counterclockwise to be extruded and matched with the convex plate 181. The first torsion spring 201 is connected between the extrusion plate 20 and the adjacent mounting frame 19. The second gear 21 that meshes with each other is fixedly connected to the side where the two adjacent extrusion plates 20 are close to each other.

[0035] When using the device, the counterclockwise revolution of the partition 9 will also drive the mounting frame 19 and the extrusion plate 20 to revolve counterclockwise. When the extrusion plate 20 on the right side revolves counterclockwise until it contacts the convex plate 181, the extrusion plate 20 on the right side will be squeezed by the convex plate 181 and rotated toward the side close to the cloth bag 11. Under the action of the second gear 21, the extrusion plate 20 on the left side will also rotate toward the side close to the cloth bag 11, and the first torsion spring 201 will be deformed. The two extrusion plates 20 squeeze the cloth bag 11 from the upper and lower sides, which will cause the left end of the cloth bag 11 to retract to the right. When the extrusion plate 20 on the right side revolves counterclockwise until it is disengaged from the convex plate 181, under the action of the first torsion spring 201 resetting, the extrusion plate 20 will also rotate in the opposite direction and no longer squeeze the cloth bag 11. At this time, the cloth bag 11 can be quickly flattened under the action of the first spring 14 resetting, thereby shaking off the dust.

[0036] like Figure 2 and Figure 8 As shown, the knocking assembly includes an extrusion wheel 22, a sliding plate 23, a guide rod 24, a knocking plate 25 and a second spring 26. The right end of the rotating shaft 8 is fixedly connected to the extrusion wheel 22. The right side of the processing box 6 is slidably connected to three sliding plates 23 with equal distances around the circumference. The extrusion wheel 22 rotates and is pressed and matched with the sliding plate 23. Three groups of guide rods 24 with equal distances around the circumference are fixedly connected to the surface of the processing box 6. A group of guide rods 24 is composed of two and is symmetrically arranged on the left and right. A knocking plate 25 is slidably connected between the two guide rods 24 of each group. The knocking plate 25 is provided with equal distances. Protrusions for knocking are provided on the side of the knocking plate 25 close to the processing box 6. The left end of the knocking plate 25 is inserted into the adjacent sliding plate 23. A second spring 26 is connected between the knocking plate 25 and the adjacent guide rod 24.

[0037] When the device is used, the rotation of the rotating shaft 8 drives the extrusion wheel 22 to rotate, and the rotation of the extrusion wheel 22 drives the sliding plate 23 to slide outward, and the sliding plate 23 slides outward, driving the knocking plate 25 to slide outward, and the second spring 26 is deformed. When the extrusion wheel 22 rotates to disengage from the sliding plate 23, under the action of the second spring 26 resetting, the knocking plate 25 slides inward and resets to knock on the processing box 6, so that the dust on the inner wall of the processing box 6 is shaken off.

[0038] Embodiment 2: Based on embodiment 1, Figure 2 , Fig. 9 and Fig.10As shown, it also includes a cleaning assembly for cleaning dust on the partition 9, the cleaning assembly includes a spiral rod 27, a guide rod 271, a second torsion spring 272, a scraper 28, a contact block 29, a sliding rod 30, a third spring 31, a flat plate 32 and a protrusion 33, one side of the outer end of the partition 9 is rotatably connected to the spiral rod 27, the second torsion spring 272 is connected between the spiral rod 27 and the adjacent partition 9, the other side of the outer end of the partition 9 is fixedly connected to the guide rod 271, the guide rod 271 is slidably connected to the scraper 28, and the scraper 28 and the spiral rod in the same space 27 is connected by a spiral, the scraper 28 is V-shaped and fits with the two adjacent partitions 9, the left part of the spiral rod 27 is fixedly connected to the contact block 29, the left part of the processing box 6 is slidably connected to the sliding rod 30, one end of the sliding rod 30 extends into the processing box 6, the sliding rod 30 slides upward and is pressed and matched with the adjacent contact block 29, a third spring 31 is connected between the sliding rod 30 and the processing box 6, the other end of the sliding rod 30 is fixedly connected to the flat plate 32, and a protrusion 33 is fixedly connected to the toothed ring 18, and the protrusion 33 revolves counterclockwise and is pressed and matched with the flat plate 32.

[0039] When using the device, the toothed ring 18 rotates to drive the protrusion 33 to rotate. When the protrusion 33 rotates to contact the flat plate 32, the protrusion 33 continues to rotate to push the flat plate 32 to move upward. The upward movement of the flat plate 32 drives the sliding rod 30 to slide upward, the third spring 31 is deformed, the sliding rod 30 slides upward to squeeze the contact block 29, and then drives the spiral rod 27 to rotate, the second torsion spring 272 is deformed, the rotation of the spiral rod 27 drives the scraper 28 to slide to the right, and when the protrusion 33 rotates to disengage from the flat plate 32, under the action of the third spring 31 resetting, the sliding rod 30 drives the flat plate 32 to move downward and reset. After the sliding rod 30 moves downward, it no longer squeezes the contact block 29. Under the action of the second torsion spring 272 resetting, the spiral rod 27 reverses and drives the scraper 28 to slide to the left and reset. The scraper 28 slides left and right to scrape and clean the dust attached to the partition 9.

[0041] When the device is used, the smoke entering the hollow cylinder 5 will drive the spiral blades 35 to rotate. The rotation of the spiral blades 35 can guide the smoke to flow along a predetermined path, reduce turbulence and eddy currents in the flow process, thereby improving the overall flow stability, and the smoke transported downward can also be preliminarily filtered through the filter 36. At the same time, rotating and opening the fixed cylinder 51 can also facilitate the cleaning of the filter 36.
