[0002] In recent years, the impact of waste batteries on the environment has become one of the hot topics in the domestic media. Whether in the atmosphere or buried deep underground, the heavy metal components of waste batteries will overflow with the seepage, causing groundwater and soil pollution, which will seriously endanger human health over time. Before the waste lithium batteries are crushed and recycled, it is usually necessary to heat-treat the harmful substances such as sulfides and nitrogen-containing compounds in the waste lithium batteries so that the harmful substances can be fully separated. The pyrolysis process can be effectively completed by thermal desorption equipment. However, after the pyrolysis of waste lithium batteries, a large amount of dust and flue gas are usually generated, which requires corresponding flue gas treatment equipment to treat it.

[0003] During use, the waste lithium battery pyrolysis flue gas treatment devices in the prior art mostly simply discharge the flue gas directly after filtering. This treatment method is not effective in removing dust in the flue gas, and the filter surface will be clogged after a period of use, thereby affecting the device's treatment of the flue gas and being unfavorable for use.

[0004] Therefore, a waste lithium battery pyrolysis flue gas treatment device is needed to solve the problem in the prior art that the dust removal effect in the flue gas is poor by simply discharging the flue gas directly after filtering, and the filter surface will be clogged after a period of use, thereby affecting the device's treatment of the flue gas.

[0023] See also Figure 1-5The utility model provides a waste lithium battery pyrolysis flue gas treatment device, comprising a spray barrel 1, an air pump 3 is arranged on one side of the spray barrel 1, a filter box 2 is arranged on one side of the air pump 3, an air inlet pipe of the air pump 3 is connected and fixedly arranged with the inner cavity of the spray barrel 1, an air outlet pipe of the air pump 3 is connected and fixedly arranged with the inner cavity of the air pump 3, a water storage shell 5 is arranged on the top of the inner cavity of the spray barrel 1, a plurality of Y-shaped spray heads 6 are connected and fixedly arranged at the bottom of the water storage shell 5, a rotating tube 9 is rotatably connected at the middle position of the top of the spray barrel 1, the bottom of the rotating tube 9 is connected and fixedly arranged with the inner cavity of the water storage shell 5, a motor 10 is fixed on the top surface of the spray barrel 1 on one side of the rotating tube 9, and the output end of the motor 10 A first gear 11 is fixedly sleeved on the outer circumference, and a second gear 12 is fixedly sleeved on the outer circumference of the rotating tube 9 near the first gear 11. The first gear 11 and the second gear 12 are meshingly connected. A water inlet pipe 13 is inserted on the top of the rotating tube 9. After the smoke is transported to the interior of the spray barrel 1, the dust contained in the smoke is mixed into the water body by the moisture sprayed from the spray head 6 during the rotation of the water storage shell 5. After thus treated, the smoke is transported by the air pump 3 into the interior of the filter box 2 and filtered by the telescopic plate 16, thereby improving the treatment effect of the smoke, and it is not easy to be blocked on the surface of the telescopic plate 16 after a short period of use.

[0024] Further as Figure 3 and Figure 5 As shown, it is worth specifically explaining that the bottom of the water inlet pipe 13 extends to the inner cavity position of the rotating tube 9, and a slot 14 is provided at the top of the inner circumference of the rotating tube 9. An insert ring 15 is inserted into the slot 14. The inner circumference of the insert ring 15 is fixed to the outer circumference of the water inlet pipe 13. When the rotating tube 9 rotates, the slot 14 can be resisted by the insert ring 15, thereby limiting the rotation trajectory of the rotating tube 9, and the setting of the insert ring 15 can improve the sealing effect of the connection between the water inlet pipe 13 and the rotating tube 9.

[0025] Further as Figure 3 As shown, it is worth specifically explaining that a telescopic plate 16 is fixed to the surface of one side of the water storage shell 5, and a scraper 17 is fixed to one side of the telescopic plate 16. The surface of one side of the scraper 17 is in contact with the inner circumference of the spray barrel 1. When the water storage shell 5 rotates, the telescopic plate 16 and the scraper 17 are driven to move. Due to the telescopic reset characteristics of the telescopic plate 16, the scraper 17 can be close to the inner circumference of the spray barrel 1 when the spray head 6 rotates, so as to play a friction cleaning role, thereby removing dust attached to the inner circumference of the spray barrel 1.

[0026] Further as Figure 1 and Figure 2As shown, it is worth explaining in detail that two filter plates 18 are inserted into the inner cavity of the filter box 2, and two groups of symmetrically distributed positioning grooves 19 are provided at both ends of the inner wall of the filter box 2. Positioning strips 20 are inserted inside the positioning grooves 19, and one end of the positioning strip 20 passes through the positioning grooves 19 and is fixed to the surface of one end of the filter plate 18 at the adjacent position. The surface of one side of the filter box 2 is rotatably connected with a rotating plate 22, and the surface of the rotating plate 22 is threadedly connected with a bolt 4. Two threaded holes 21 are provided on the surface of one side of the filter plate 18, and one end of the bolt 4 extends to the inside of the threaded hole 21 at the adjacent position. When the filter plate 18 needs to be replaced, the bolt 4 is separated from the rotating plate 22 through the threaded structure by rotating the bolt 4, so that the bolt 4 can be disengaged from the inside of the threaded hole 21 at the adjacent position, so that the filter plate 18 can be extended out of the filter box 2 after the rotating plate 22 is rotated so that it no longer blocks the filter plate 18.

[0027] This solution has the following working process: in actual use, when the user needs to connect the smoke delivery pipe to the air inlet pipe of the spray barrel 1, the water outlet pipe of the spray barrel 1 is connected to the external drain pipe, and is connected to the air outlet pipe of the filter box 2 through an external pump body, the water inlet pipe 13 is externally connected to a water pipe for conveying water flow, and the water conveyed by the water inlet pipe 13 can flow to the inner cavity position of the water storage shell 5 through the rotating tube 9, and can be sprayed out from the spray head 6, and the motor 10 is started to rotate the first gear 11, so that the rotating tube 9 can rotate under the meshing action between the first gear 11 and the second gear 12, so that the water storage shell 5 can rotate, so as to expand the activity range of the water sprayed by the spray head 6, thereby improving the contact effect between the sprayed water and the smoke entering the inner cavity of the spray barrel 1, so that the smoke The dust contained in it can be mixed into the water body. When the water storage shell 5 rotates, the telescopic plate 16 and the scraper 17 are driven to move. Due to the telescopic reset characteristics of the telescopic plate 16, the scraper 17 can be close to the inner circumference of the spray barrel 1 when the spray head 6 rotates, and it plays a friction and cleaning role, so that the dust attached to the inner circumference of the spray barrel 1 can be removed. When it is necessary to discharge the water mixed with dust, the valve of the water outlet pipe of the spray barrel 1 is opened to allow the sewage to enter the internal discharge of the external drainage pipe. After the flue gas is sprayed, the air pump 3 is started to allow the flue gas to enter the interior of the filter box 2, so that under the action of the external pump body of the air outlet pipe of the filter box 2, the flue gas passes through the two filter plates 18 and is discharged from the interior of the filter box 2, thereby improving the treatment effect of the flue gas, and it is not easy to be blocked on the surface of the telescopic plate 16 after a short period of use.

[0028] According to the above working process, it can be known that: after the smoke is transported to the interior of the spray barrel 1, the dust contained in the smoke is mixed into the water body by the moisture sprayed from the spray head 6 during the rotation of the water storage shell 5, and the smoke after treatment enters the interior of the filter box 2 after being transported by the air pump 3 and filtered by the telescopic plate 16, thereby improving the treatment effect of the smoke, and it is not easy to be blocked on the surface of the telescopic plate 16 after a short period of use, thereby improving the practicality of the device, and by rotating the bolt 4 to extend it out of the outside of the adjacent threaded hole 21, the filter plate 18 can be extended out of the filter box 2 after adjusting the angle of the filter plate 18, thereby facilitating the replacement operation of the filter plate 18, thereby saving the time spent by the user in regularly replacing the filter plate 18, thereby improving the convenience of use of the device.

[0029] Further as Figure 4 As shown, it is worth specifically explaining that a support ring 8 is fixed at a position near the inner circumference of the spray barrel 1 near the water storage shell 5, and a support groove 7 is provided on the surface of the water storage shell 5 away from the telescopic plate 16, and the support groove 7 and the support ring 8 are slidably connected. When the water storage shell 5 rotates, the inner cavity surface of the support groove 7 will conflict with the support ring 8, thereby limiting the movement trajectory of the water storage shell 5 and supporting the water storage shell 5 to prevent it from shaking during rotation.

[0030] In summary: after the smoke is transported to the interior of the spray barrel 1, the dust contained in the smoke is mixed into the water body by the water sprayed from the spray head 6 during the rotation of the water storage shell 5, and the smoke after treatment is then transported by the air pump 3 into the interior of the filter box 2 and filtered by the telescopic plate 16, thereby improving the treatment effect of the smoke, and it is not easy to be blocked on the surface of the telescopic plate 16 after a short period of use, thereby improving the practicality of the device, by rotating the bolt 4 to extend it outside the adjacent threaded hole 21, so that the filter plate 18 can extend out of the filter box 2 after adjusting the angle of the filter plate 18, thereby facilitating the replacement of the filter plate 18, thereby saving the time spent by the user to regularly replace the filter plate 18, thereby improving the convenience of use of the device, because the inner cavity surface of the support groove 7 will conflict with the support ring 8 when the water storage shell 5 rotates, so that it can limit the movement trajectory of the water storage shell 5, and can support the water storage shell 5 to prevent it from shaking during rotation.

[0031] The air pump 3 and the motor 10 can be purchased on the market. The air pump 3 and the motor 10 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
