[0002] Lithium iron phosphate is a lithium-ion battery electrode material with the chemical formula LiFePO4 (LFP for short). It is mainly used in various lithium-ion batteries. Lithium iron phosphate is an important raw material for the production of lithium batteries. Currently, lithium iron phosphate will produce acidic tail gas during the production and preparation process. If the acidic tail gas is directly discharged into the atmosphere, it will cause serious pollution to the atmospheric environment. Therefore, it is usually necessary to treat the acidic tail gas through a spray tower before discharging it into the atmosphere.

[0023] The present invention also discloses a method for using a tail gas treatment device for lithium iron phosphate production, which uses the tail gas treatment device for lithium iron phosphate production, comprising the following steps:

[0024] S1. Exhaust gas generated by lithium iron phosphate production is discharged into the interior of the spray tower through an air inlet pipe, an exhaust fan is started to blow the exhaust gas toward the top of the spray tower, and a water pump is started simultaneously to extract the alkaline liquid in the water collecting tank into the interior of the drain pipe, so that the alkaline liquid is sprayed into the interior of the spray tower through a nozzle, and the acidic substances in the tail gas of lithium iron phosphate production are neutralized by the alkaline liquid, so as to treat the tail gas generated by the lithium iron phosphate production;

[0025] S2. When treating the tail gas generated by the production of lithium iron phosphate, the guide motor is started synchronously to rotate the threaded drive rod, so that the sliding rod drives the stirring plate to rotate inside the spray tower, thereby stirring the tail gas generated by the production of lithium iron phosphate and the alkaline liquid;

[0026] S3. When the packing balls need to be replaced and cleaned, the electric push rod is started, so that the two arc-shaped threaded plates are threadedly connected with the threaded driving rod, so that the threaded driving rod drives the hollow ring and the mounting rod to move downward, so that the cross plate pushes the magnet block to move downward, so that the clamping block is separated from the inner wall of the spray tower, so that the bearing fence is plugged into the inside of the bearing plate;

[0027] S4, start the driving motor to rotate the threaded rod, so that the sliding block drives the bearing plate and the arc plate to slide inside the plug-in slot, so that the bearing plate is separated from the discharge spray tower, and the bearing fence and the filler ball are moved out synchronously;

[0028] S5. When the cross plate moves downward, it synchronously drives the arc-shaped scraper plate to scrape the inner wall of the spray tower. At the same time, the support plate drives the driving tooth plate to rotate, so that the rotating rod drives the linkage gear to rotate, so that the linkage tooth plate moves upward, drives the sealing plate to move upward, and connects the inspection port with the spray tower, so that the staff can enter the interior to inspect the components.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Through the arrangement of structures such as the treatment mechanism, the bearing mechanism, the guide mechanism, the maintenance mechanism and the spray mechanism, the tail gas produced by the lithium iron phosphate is discharged into the spray tower through the air inlet pipe. Through the arrangement of the exhaust fan, the tail gas is pushed upward, and at the same time, the guide motor is started to rotate the threaded drive rod, which drives the sliding rod and the stirring plate to rotate synchronously, thereby stirring the tail gas inside the spray tower, driving the water pump to spray the alkaline liquid into the spray tower from the nozzle, and neutralizing the acidic substances in the tail gas. Through the rotation of the stirring plate, the tail gas and the atomized alkaline liquid are stirred, so that the tail gas and the alkaline liquid are mixed more thoroughly, so that the tail gas treatment device for lithium iron phosphate production can treat the tail gas more thoroughly. At the same time, through the arrangement of the exhaust fan, it is avoided that the tail gas accumulates inside the spray tower and cannot float upward;

[0031] 2. Through the arrangement of the processing mechanism, the bearing mechanism, the guiding mechanism, the driving mechanism, the maintenance mechanism and the spraying mechanism, after the tail gas treatment device for lithium iron phosphate production has been used for a long time, the electric push rod is started to make the arc-shaped threaded plate fit with the threaded driving rod, so that the threaded driving rod is threadedly connected with the arc-shaped threaded plate, driving the hollow ring to move downward, so that the installation rod pushes the cross plate downward, driving the magnet block to push the bearing fence downward, so that the bearing fence is no longer connected with the spray tower, so that the bearing fence is plugged into the inside of the bearing plate, and the bearing plate and the bearing fence are driven to move to the outside of the spray tower through the driving mechanism, so that it is convenient for the staff to clean and replace the packing balls and the bearing fence;

[0032] 3. Through the arrangement of the processing mechanism, the bearing mechanism, the guiding mechanism, the driving mechanism, the maintenance mechanism and the spraying mechanism, when the cross plate and the supporting plate move downward, not only the arc-shaped scraping plate moves downward on the inner wall of the spray tower to scrape the inner wall of the spray tower, thereby avoiding the impurities adhering to the inside of the spray tower and affecting the exhaust gas treatment, but also the driving tooth plate can be synchronously driven to move, so that the driving gear rotates, so that the stabilizing rod drives the rotating rod to rotate, so that the linkage gear rotates, so that the linkage tooth plate moves upward, and drives the sealing plate to move upward synchronously, so that the detection port is connected with the spray tower, which is convenient for the staff to inspect the components inside the spray tower;

[0033] 4. Through the arrangement of structures such as the processing mechanism, the bearing mechanism, the guiding mechanism, the maintenance mechanism and the spraying mechanism, and through the arrangement of the filter baffle, it is prevented that when the bearing fence moves downward to scrape the spray tower, the debris on the inner wall of the spray tower falls into the water collecting tank. At the same time, when the internal components of the spray tower are inspected, the mounting bolts are synchronously rotated to disengage the mounting bolts from the water collecting tank, and the water collecting tank is disengaged from the spray tower, so that the water collecting tank falls onto the support plate, which makes it convenient for the staff to clean the interior of the water collecting tank. The arrangement of the water inlet pipe makes it convenient for the staff to replenish the alkaline solution to the inside of the water collecting tank. BRIEF DESCRIPTION OF THE DRAWINGS
