[0002] With the widespread application of lithium batteries in electric vehicles, lithium battery projects have received substantial investment and factory construction in China. Iron phosphate powder is an important raw material in lithium battery production, playing a crucial role in the manufacturing process. In the iron phosphate powder drying process, heat exchange occurs between hot air and the iron phosphate powder through convection within the dryer. The rotating drum creates a "stirring" effect, and moisture is discharged with the flue gas through a bag filter and induced draft fan at the tail end of the dryer. The dried iron phosphate powder is then stored in a warehouse via other equipment.

[0003] Currently, in the lithium battery industry, the bag filter dust collector used for drying iron phosphate powder has a problem during operation. Because the air inlet pipe is directly connected to the housing and directly connected to the bag filter area, the gas flow rate is too fast when it enters. Impurities inside the gas are not easy to settle inside the housing, which has a certain impact on the filtration of the bag. Moreover, there may be some trace residues in the filtered air, which can easily pollute the environment if directly discharged. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where the gas flow rate is too fast due to the direct connection of the air inlet pipe to the housing, which makes it difficult for impurities inside the gas to settle inside the housing and thus affects the filtration of the filter bag. Therefore, this invention proposes a ferric phosphate powder bag dust collector.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Reference Figure 1-4 A baghouse dust collector for iron phosphate powder includes a dust collection box 1, a cleaner 3 fixedly connected to the top of the dust collection box 1, and a dust hopper fixedly connected to the bottom of the dust collection box 1. It also includes an air inlet assembly, a cleaning assembly, and a slag discharge assembly. The air inlet assembly includes an interception box 201 fixedly connected to the outside of the dust collection box 1, an air inlet pipe 2 fixedly connected to the outside of the interception box 201, and a baffle plate 202 fixedly connected to the inside of the interception box 201. The interception box 201 has an opening on its side away from the air inlet pipe 2, which communicates with the inside of the dust collection box 1. The cleaning assembly includes a liquid storage tank 4 fixedly connected to the outside of the dust collection box 1, an exhaust pipe 401 disposed between the liquid storage tank 4 and the dust collection box 1, and a dehumidifying filter cartridge 402 fixedly connected to the top of the liquid storage tank 4. The slag discharge assembly is fixedly connected to the bottom of the dust hopper and is used to discharge impurities from inside the dust hopper.

[0029] When dust-laden gas passes through the interception box 201, the baffle plate 202 inside it intercepts the air, reducing the air velocity and facilitating the natural settling of dust in the bag chamber and ash hopper. The liquid storage tank 4 can be filled with clean water or detergent as needed. After the filtered air enters the interior, it is cleaned again using liquid. The cleaned air is then filtered by the dehumidifying filter cartridge 402 to keep the exhaust gas dry. In addition, the cleaner 3 is equipped with a pulse generator and an air nozzle. The pulse generator provides an air source, which is then sprayed out by the air nozzle. The air nozzle and the filter bag are symmetrically arranged, and the resulting high-pressure airflow rushes into the filter bag and removes the impurities adsorbed on the outer surface of the filter bag.

[0030] The barrier plate 202 is provided in several ways, and the barrier plates 202 are arranged in an alternating manner. The bottom wall of the interception box 201 is provided with an inclined plate 203, and the downward end of the inclined plate 203 extends through the interception box 201 into the dust removal box 1.

[0031] The baffle plates 202 are all curved, and the intercepted particles will move forward along the direction of the curve. The inclined plate 203 is inclined downward. After the baffle plates 202 intercept some impurities, the impurities will fall into the ash hopper along the inclined plate 203.

[0032] Reference Figure 4 A baghouse dust collector for iron phosphate powder is further characterized in that the upper end of the exhaust pipe 401 is connected to the exhaust port of the dust collector housing 1, and the lower end of the exhaust pipe 401 extends into the liquid inside the liquid storage tank 4. Solenoid valves 7 are installed on the exterior of both the exhaust pipe 401 and the inlet pipe 2. An inlet fan is installed at the lower end of the dehumidifying filter cartridge 402, an activated carbon adsorption layer is installed inside the dehumidifying filter cartridge 402, and an outlet pipe is installed at the upper end of the dehumidifying filter cartridge 402.

[0033] The solenoid valve 7 can control the air volume entering the exhaust pipe 401, making it convenient to control the cleaning efficiency. The dehumidifying filter cartridge 402 uses the intake fan to maintain the efficiency of the incoming air. The activated carbon adsorption layer inside the dehumidifying filter cartridge 402 can further adsorb small particles, odors and moisture in the air, keeping the exhaust gas clean and dry.

[0034] Reference Figure 5A baghouse dust collector for iron phosphate powder further includes a slag discharge assembly comprising a slag discharge pipe 5 fixedly connected to the bottom of the ash hopper, a drive motor 501 fixedly connected to the outside of the slag discharge pipe 5, a grid shaft 502 fixedly connected to the output end of the drive motor 501, and a stirring shaft 505 rotatably connected inside the ash hopper. The outer surface of the grid shaft 502 is provided with multiple compartments. Both the ends of the grid shaft 502 and the stirring shaft 505 are fixedly connected to pulleys 503. A transmission belt 504 is sleeved between two pulleys 503. A protective shell 6 is provided outside the slag discharge pipe 5 to protect the pulleys 503 and the transmission belt 504.

[0035] When impurities fall into the slag discharge pipe 5, they will accumulate inside the compartment of the grid shaft 502. Then, the drive motor 501 is started to drive the grid shaft 502 to rotate, which can carry the impurities to the outside. The outermost edge of the grid shaft 502 is attached to the inside of the slag discharge pipe 5, which can maintain the sealing of the dust collector 1 and transport the impurities out. The outer surface of the stirring shaft 505 is equipped with stirring blades. Driven by the pulley 503 and the transmission belt 504, it can rotate at the same speed as the grid shaft 502. When the stirring shaft 505 rotates, it can stir up the accumulated impurities and reduce the blockage between impurities.

[0036] Specifically, in use, this utility model works as follows: First, the solenoid valve 7 is opened to allow dust-laden gas to be transported into the dust collector 1 through the inlet pipe 2. During transport, the gas first passes through the interception box 201, where the internal baffle plate 202 obstructs the airflow, slowing its entry and intercepting some larger particulate impurities. Then, the gas is filtered by the filter bag, removing most of the impurities. The filtered gas then enters the liquid storage tank 4 through the exhaust pipe 401, where it is cleaned by the internal liquid before being discharged through the dehumidifying filter cartridge 402. The dehumidifying filter cartridge 402 further adsorbs and filters the gas, reducing impurities, odors, and moisture in the air, thus maintaining the quality of the discharged gas. After drying, the filtered impurities adhere to the filter bag. The cleaner 3 is then activated, using a pulse generator to provide air supply in conjunction with the air nozzles. The air nozzles and filter bags are symmetrically arranged, and the resulting high-pressure airflow rushes into the filter bag to remove the impurities adsorbed on the outer surface of the filter bag. The removed impurities fall into the ash hopper and then accumulate inside the slag discharge pipe 5. The drive motor 501 is then activated to rotate the grid shaft 502, which carries the impurities to the outside. The stirring shaft 505, driven by the pulley 503 and the transmission belt 504, rotates at the same speed as the grid shaft 502. When the stirring shaft 505 rotates, it agitates the accumulated impurities, reducing blockage between them.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
