Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a bag filter for copper oxide production. Background Art

[0002] A large amount of wastewater is generated during the production of copper oxide. In the process of wastewater treatment, not only the pollutants in the wastewater need to be removed, but also the solid waste residue in the wastewater needs to be removed. The most commonly used method for removing solid waste residue is bag filter. The existing bag filter generally adopts the upper end to feed the liquid into the filter bag, and the filter bag is supported by a filter basket outside the filter bag. The clear liquid flows out of the filter bag to the lower end outlet of the filter, and the filter residue is retained inside the filter bag. After a period of use, a lot of solid filter residue will be retained in the filter bag. Therefore, the filter needs to be opened manually every once in a while, and dozens of bolts need to be unscrewed when opening the filter, which is not only inefficient, but also labor-intensive for workers. After opening the filter, the filter bag needs to be manually taken out for cleaning or replacement, and then the filter bag needs to be put back into the filter, which increases the consumption of human resources. Manual cleaning is prone to damage to the filter bag, increasing the probability of filter bag damage, and frequent disassembly of the filter will reduce the life of the filter and affect production capacity.

[0028] Embodiment 1

[0029] like Figure 1-Figure 5 As shown, the bag filter for copper oxide production proposed by the utility model includes a housing 1, a cover plate 2, a support bracket 3, an air inlet pipe 4, an air outlet pipe 5, a dust outlet pipe 6, a telescopic rod 7, a filter screen 8, a lifting ring 9, a wave rod 10, a rotating plate 11, a locking telescopic rod 12, a locking member 13, a supporting rod 14, a sliding bracket 15, a spring 16, a sliding rod 17, a fixed bracket 18 and a friction member 19;

[0030] A cover plate 2 is provided on the top of the shell 1; a support bracket 3 is provided on the side of the outer end surface of the shell 1; a telescopic rod 7 is provided on the top of the cover plate 2; an air inlet pipe 4 is provided on the side of the shell 1; an air outlet pipe 5 is provided on the side of the shell 1; a dust removal pipe 6 is provided on the bottom of the shell 1; a control valve is provided on the side of the dust removal pipe 6; a filter screen 8 is provided inside the shell 1; a discharge structure for discharging dust is provided on the filter screen 8; a dust cleaning structure for dust cleaning processing is provided inside the filter screen 8;

[0031] The discharge structure includes a locking telescopic rod 12; a locking member 13 is provided on the output end of the locking telescopic rod 12; a rotating plate 11 rotatably connected is provided on the bottom of the filter 8; the locking member 13 is in contact with the bottom of the rotating plate 11; the top of the locking telescopic rod 12 is connected to the bottom of the filter 8;

[0032] The dust cleaning structure includes a lifting ring 9; a sliding bracket 15 with a sliding connection is provided on the top of the lifting ring 9; a supporting rod 14 is provided on the side of the sliding bracket 15; a wave rod 10 is provided on the bottom of the cover plate 2; the side of the wave rod 10 is in contact with the supporting rod 14; a sliding rod 17 is provided on the end of the sliding bracket 15 away from the supporting rod 14; a fixed bracket 18 is provided on the top of the lifting ring 9; a through hole is provided on the fixed bracket 18; the inner wall of the through hole is slidably connected with the sliding rod 17; a spring 16 is provided on the side of the fixed bracket 18; the end of the spring 16 away from the fixed bracket 18 is connected to the side of the sliding bracket 15, and a friction member 19 is provided on the side of the sliding rod 17, and the friction member 19 is in contact with the inner wall of the filter screen 8.

[0033] In this embodiment, the device can effectively improve the stability of the filtering effect of the filter 8 under long-term continuous operation. Compared with the traditional device, the dry shaking dust removal method adopted in the device can avoid the dust and moisture from combining to form a paste, thereby maintaining the dryness of the inside of the shell 1 of the device and avoiding the formation of paste sticking to the inner wall of the shell 1, thereby improving the cleaning efficiency of the inside of the shell 1.

[0034] When the device is in working state, air enters into the shell 1 and the filter 8 through the air inlet pipe 4, and is finally discharged from the air outlet pipe 5. During the process of one-way airflow, the structure of the filter 8 can effectively intercept copper oxide in the air.

[0035] When the airflow circulates in one direction, the telescopic rod 7 drives the lifting ring 9 to lift and reciprocate, so that the friction part 9 on the lifting ring 9 can shake the filter screen 8 at different heights, thereby expanding the shaking processing range, thereby clearing the blocked dust more thoroughly.

[0036] During the lifting and reciprocating sliding process of the lifting ring 9, since the spring 16 is connected to the fixed bracket 18, the spring 16 drives the sliding bracket 15 to be squeezed in the direction close to the wave tube 10, and the abutting rod 14 on the side of the sliding bracket 15 contacts and squeezes the side of the wave tube 10. At this time, as the lifting ring 9 is lifted and slid vertically, since the side of the wave tube 10 has a regular undulating structure, when the abutting rod 14 moves to the protruding position of the wave tube 10, it slides in the direction of the spring 16, and when the abutting rod 14 moves to the concave position of the wave tube 10 and contacts, it moves in the direction of the wave tube 10. The abutment rod 14 slides linearly according to the raised structure on the side of the wave tube 10, thereby driving the sliding bracket 15 to slide linearly back and forth on the lifting ring 9, and the sliding bracket 15 drives the sliding rod 17 and the friction member 19 to achieve linear reciprocating sliding. Since the friction member 19 is in contact with the inner wall of the filter screen 8, during the process of linear reciprocating sliding, the friction member 19 periodically contacts the inner wall of the filter screen 8, thereby forming a shaking effect of the filter screen 8. By generating shaking on the filter screen 8, the effect of the device in preventing the filter screen 8 from being blocked by dust can be improved.

[0037] Since the locking piece 13 is connected to the bottom of the rotating plate 11, and the rotating plate 11 rotates with the bottom of the filter screen 8, when the locking telescopic rod 12 linearly transmits the locking piece 13, since a transmission groove is provided on the locking piece 13, the transmission combination of the transmission groove and the locking telescopic rod 12 can achieve the effect of driving the rotating plate 11 to rotate through the locking telescopic rod 12. The structure of the transmission groove can prevent the linear reciprocating sliding of the output end of the locking telescopic rod 12 from getting stuck with the rotation of the rotating plate 11.

[0038] Embodiment 2

[0039] like Figure 1-Figure 5 As shown, the bag filter for copper oxide production proposed by the utility model is compared with the first embodiment. In this embodiment, a locking transmission member is provided on the output end of the locking telescopic rod 12, and a transmission groove is provided on the locking member 13, and the inner wall side of the transmission groove is slidably connected with the locking transmission member.

[0040] Through the combination of the locking transmission member and the transmission groove, the rotating plate 11 and the locking member 13 can be ensured to rotate stably during the transmission of the locking telescopic rod 12, thereby achieving the rotation control effect of the rotating plate 11 by the device, and further achieving the discharge control effect of the device.

[0041] Embodiment 3

[0042] like Figure 1-Figure 5As shown, the bag filter for copper oxide production proposed by the utility model is compared with the second embodiment. In this embodiment, a through hole is provided on the bottom of the filter screen 8, a pin is provided on the inner wall of the through hole, the pin is rotatably connected to the side of the rotating plate 11, a sealing member is provided on the side of the rotating plate 11, the sealing member is in contact and squeezed with the inner wall of the through hole, arc-shaped fillets are provided on the top and bottom sides of the rotating plate 11, the arc-shaped fillets are in contact and slide with the side of the inner wall of the through hole, and there is a distance between the contact position of the locking transmission member with the transmission groove and the center point inside the transmission groove.

[0043] The pin shaft can ensure the vertical rotation stability of the rotating plate 11, thereby ensuring smooth material unloading of the device. The arc-shaped rounded corner structure can prevent the device from being stuck in rotation. At the same time, the sealing structure can avoid leakage at the bottom of the device. The spacing between the contact position between the locking transmission member and the transmission groove and the inner center point of the transmission groove can make the transmission groove tilt during the process of the locking transmission member pushing the transmission groove, rather than being stuck due to vertical pressure. The tilted transmission groove drives the rotating plate 11 to rotate through the connection combination of the locking member 13 and the rotating plate 11, thereby achieving the material unloading control effect.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
