[0002] Waste alkali filtration devices are mainly used to remove impurities from industrial waste alkali solutions, such as label paper, fibers, sulfides, and organic pollutants, in order to improve the alkali reuse rate and reduce environmental pollution.

[0003] Currently, waste alkali filtration devices use filter screens to filter impurities. Impurities accumulate on the filter screens, and cleaning them by removing the screens is time-consuming and labor-intensive. It is also inconvenient to discharge the filtered waste residue, which affects the filtration efficiency. Therefore, a waste alkali filtration device is proposed to solve the above problems.

[0037] The filter section 4 is located inside the filter tank 1 and is used to filter impurities in the waste alkali. The filter section 4 is installed in the middle of the filter tank 1 to separate impurities and alkali in the waste alkali solution. The filter section 4 increases the filtration area and improves the filtration efficiency.

[0038] The cleaning part 2 is rotatably disposed inside the filter tank 1 and fits against the inner wall of the filter part 4. It is used to clean the impurities on the filter part 4. The cleaning part 2 rotates on the filter part 4 to scrape off the impurities on the filter part 4 and prevent impurities from adhering to the surface of the filter part 4.

[0039] The discharge section 3 is located below the filter section 4 and extends to the outside of the filter tank 1. It is used to discharge impurities on the filter section 4. The discharge section 3 is inserted into the filter section 4. The impurities on the filter section 4 are transported to the outside of the filter tank 1 through the discharge section 3. The impurities are discharged without replacing the filter section 4, thereby improving the efficiency of impurity discharge.

[0040] The discharge section 3 includes a screw conveyor 31 installed on the filter tank 1 and a filter hole 32 on the outer wall of the screw conveyor 31 installed inside the filter tank 1. The filter hole 32 is used to separate the alkaline solution in the impurities and to discharge the alkaline solution inside the screw conveyor 31, so as to prevent the alkaline solution from being discharged from the discharge section 3.

[0041] In use, the filter unit 4 is installed on the filter tank 1 and is plugged into the discharge unit 3. The filter tank 1 filters the waste alkaline solution. The cleaning unit 2 cleans the impurities on the filter unit 4.

The top of the rotating shaft 21 is provided with a drive unit 22 that is fixedly installed with the cover plate 12. The drive unit 22 is an electric motor. The drive unit 22 drives the rotating shaft 21 and the cleaning brush 23 to rotate. The cleaning brush 23 sweeps away impurities on the filter cylinder 42 and the filter screen cylinder 43. The impurities fall into the collection screen cylinder 44.

[0050] In a specific embodiment, the discharge section 3 includes a connector 33 disposed on the auger elevator 31 and facing the mounting pipe 45. The mounting pipe 45 and the connector 33 are connected and installed together. Impurities in the filter screen cylinder 43 enter the auger elevator 31 through the mounting pipe 45 and the connector 33, and the alkaline solution is discharged through the filter hole 32 located in the tank 11 on the auger elevator 31, so that the auger elevator 31 only discharges the impurities in the tank 11.

[0051] It also includes a discharge pipe 34 installed on the screw conveyor 31 and located outside the tank body 11;

[0052] It also includes a drive unit 35 located at one end of the auger hoist 31 and used to drive the auger hoist 31 to run. The drive unit 35 is a motor or electric motor.

[0053] In one embodiment, the auger elevator 31 includes a housing and a rotating rod disposed within the housing. The outer wall of the rotating rod is provided with a spiral conveying blade. The rotating rod is fixedly installed with the output shaft of the drive unit 35. The housing is fixedly installed with the insertion pipe 33. A filter hole 32 is opened on the housing. The drive unit 35 drives the spiral conveying blade on the rotating rod to rotate inside the housing, conveying impurities and allowing the impurities to be discharged outside the tank 11. This achieves automatic cleaning of impurities attached to the surface of the filter screen without replacing the filter screen, and automatic discharge of impurities, thus avoiding affecting the filtration efficiency.
