Technical Field

[0001] The utility model relates to the technical field of pyrolysis kilns, in particular to a cooling device for a waste lithium battery pyrolysis kiln. Background Art

[0002] The pyrolysis kiln is one of the important measures for environmental protection and resource recycling to recycle waste lithium batteries, and pyrolysis is one of the key steps in the treatment of waste lithium batteries.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model can effectively improve the cooling efficiency by setting a heat exchanger device and two first fans. Through the first air duct set by the heat exchanger device, when the gas flows into the first integrated pipe through the first air duct, the gas will flow into the several copper tubes connected with it through the first integrated pipe, and the several copper tubes are sleeved with a plurality of annular fins. At this time, the first motors installed on both sides of the fixing plate installed at the lower end of the first fixing block are driven to work, so that the two first fans located in the two air holes can be rotated. The two first fans rotate to circulate air, and the circulated air can cool the several annular fins sleeved on the several copper tubes in the box body, so that the gas flowing in the several copper tubes is cooled. The cooled gas flows into the second integrated pipe connected with it through the output ends of the several copper tubes, and then the gas is transported through the second air duct connected with the second integrated pipe. In this way, efficient heat exchange is carried out through the heat exchanger device, which effectively improves the cooling efficiency, reduces energy consumption, and solves the problem of high energy consumption during use.

[0014] 2. The utility model can circulate and convert the gas to cool it down by means of the wind tube and the circulation pump. By starting the second motor installed on the cross fixing frame in the wind tube, the output end of the second motor drives the second fan to rotate so that the gas in the pyrolysis kiln is transported through the vent duct. The transported gas is heat-exchanged and air-cooled with the two first fans through the heat exchanger device. Then, by starting the circulation pump, the gas flowing into the interior from the input end is circulated and converted, and the gas enters the pyrolysis kiln through the third air duct, so that the temperature in the pyrolysis kiln is regulated, thereby avoiding safety hazards caused by excessive temperature during the pyrolysis process when the pyrolysis kiln is working.

[0015] 3. The utility model can effectively filter the circulating gas through the filter box and the two fourth flanges, and can also conveniently disassemble and replace the filter element inside the filter box. When the gas in the ventilation duct is transported to the filter box which is fixedly connected with the fourth flange and the fifth flange by the second bolt, the filter element in the filter box can filter the gas circulating inside. The fourth flange is fixedly connected with the first flange by the second bolt, so that the filtered gas flows into the first air duct. The filter element inside the filter box can be conveniently replaced by removing the second bolt.

[0016] 4. The utility model can gather the gas and evenly disperse it in the several copper tubes for heat dissipation through the first air duct, the first integrated tube and the several copper tubes and the second integrated tube and the second air duct. The gas after cooling can be gathered and discharged, and the gas in the first air duct can flow into the first integrated tube set in the heat exchanger device. The gas will be dispersed and guided through the first integrated tube, so that the gas can flow evenly to the several copper tubes connected thereto. The cooled gas flows through the several copper tubes to the second integrated tube connected thereto. Then the gas can gather the cooled gas through the second integrated tube, so that it can flow to the second air duct for transportation. Such a setting can gather the gas and evenly disperse it for cooling. The dispersed and cooled gas is then gathered for transportation. The gas can be diverted through such a parallel design, thereby reducing the pressure loss of the gas in the pipeline, which is more stable and reliable.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
