[0023] refer to Figure 1-6 The washing device shown includes a washing tank 1, a support frame 2, a feed inlet 3, a drive motor 4, a stirring rod 5, a drying box 6, an inspection door 7, a temperature controller 8, a discharge mechanism 9, a placement platform 10, a screen changing platform 11, a screen changing mechanism, and a heating source 19. The bottom of the washing tank 1 is supported by the support frame 2 to ensure the stability of the washing tank 1. The screen changing platform 11 is located behind the support frame 2. A drying chamber 6 and a storage platform 10 are located on the right side of the washing tank 1. The washing tank 1 is connected to the interior of the drying chamber 6 via a drain hole 24 at its bottom, allowing the washed liquid to flow smoothly into the drying chamber 6 for further processing. The drying chamber 6 contains a removable filter screen 16. An inspection door 7 is hinged to the side wall of the drying chamber 6 for easy inspection and cleaning. A heating source 19 is also located inside the drying chamber 6 for drying the filtered material. A temperature controller 8 is connected to the top of the drying chamber 6 to precisely control the operating temperature of the heating source 19, preventing overheating or insufficient drying of the material. A waste drain hole 25 is located at the bottom of the drying chamber 6 to drain waste liquid generated during the drying process.

[0024] In one embodiment of this invention, the washing tank 1 has an inlet 3 for slurry or raw materials on its top surface. An agitator 5 is installed inside the washing tank 1 to thoroughly agitate and wash the materials entering the washing tank 1. A drive motor 4 is also installed on the top surface of the washing tank 1, and the output shaft of the drive motor 4 is connected to the agitator 5 to drive the agitator 5 to rotate.

[0025] In one embodiment of this invention, to facilitate the removal and replacement of the filter screen 16, the drying chamber 6 is equipped with a discharge mechanism 9. This mechanism can smoothly pull the filter screen 16 out of the drying chamber 6. The drying chamber 6 is also provided with a discharge hole adapted to the filter screen 16. An auxiliary plate is provided below the through hole 21, and a screen changing platform 11 is provided with a screen changing mechanism to assist in replacing the filter screen 16. The discharge mechanism 9 is used to remove the filter screen 16 from the drying chamber 6. The discharge mechanism 9 includes an electric push rod 17, a clamp 18, and a guide rod 20. A connecting plate 26 is connected to one side of the filter screen 16. Both ends of the connecting plate 26 are equipped with clamps 18. One end of the connecting plate 26 is connected to the telescopic end of the electric push rod 17 through the clamp 18, and the other end is connected to the guide rod 20 through the clamp 18. The electric push rod 17 and the guide rod 20 are installed in parallel on both sides of the drying box 6. The guide rod 20 provides a stable guide for the extraction of the filter screen plate 16 and prevents it from deviating. After the electric push rod 17 is started, it pushes or pulls the filter screen plate 16 to move smoothly along the direction of the guide rod 20. A support plate 2727 for supporting the connecting plate 26 is also connected between the two sets of clamps 18. The support plate 2727 is located below the connecting plate 26.

[0026] In one embodiment of this invention, a screen-changing mechanism is installed on a screen-changing platform 11 to assist the operator in replacing the filter screen 16. The screen-changing mechanism includes a slider 12, a baffle 13, and a pusher plate 14. A through hole 21 is provided on the screen-changing platform 11, and a lead screw 22 is horizontally installed in the through hole 21. The slider 12 is threadedly connected to the lead screw 22, so when the lead screw 22 rotates, the slider 12 will move along the axial direction of the lead screw 22. A baffle 13 is connected to the slider 12, and the baffle 13 is used to push the pusher plate 14. A guide hole 23 or guide groove is provided on the upper surface of the screen changing table 11 corresponding to the position of the baffle 13. This is to ensure that the baffle 13 moves linearly when pushing the push plate 14. The push plate 14 is placed on the upper surface of the screen changing table 11 and can slide on its surface. The screen changing table 11 is also connected to a material changing motor 15. The output shaft of the material changing motor 15 is connected to the lead screw 22 to drive the lead screw 22 to rotate, thereby controlling the movement of the slider 12, the baffle 13 and the push plate 14. This enables the filter screen 16 to be pushed to the designated position, replacing the filter screen 16 extracted by the unloading mechanism 9, and pushing the replaced screen onto the placement table 10.

[0027] In one embodiment, the electric push rod 17 is designed with an extension length that ensures it can completely push the filter screen 16 out of the drying chamber 6 and accurately place it at the predetermined replacement position on the screen changing table 11. The screen changing table 11 corresponds to the placement table 10, which is typically used to temporarily place clean filter screens to be replaced or dirty filter screens that have been removed. For ease of operation, the height of the placement table 10 is designed to be slightly lower than the height of the screen changing table 11, allowing for a smooth transition when transferring the filter screen 16.

[0028] The working principle of this product is as follows: Aluminum hydroxide slurry or crude product is added to washing tank 1 through the inlet 3 at the top. The drive motor 4 is started, which rotates the stirring rod 5 to fully stir and wash the slurry. After washing, the washing liquid flows into the drying chamber 6 below through the drain hole 24 at the bottom of washing tank 1. The liquid passes through the filter screen 16, while the solid aluminum hydroxide is trapped on the filter screen 16. The filter screen 16, containing the aluminum hydroxide, is placed inside the drying chamber 6. The heating source 19 is started, and the temperature controller 8 controls the operation of the heating source 19 according to the set temperature to dry the aluminum hydroxide. Liquid or waste gas generated during the drying process is discharged through the waste outlet 25 at the bottom of the drying chamber 6. After drying, the electric push rod 17 in the unloading mechanism 9 is activated. The electric push rod 17 extends and pushes the connecting plate 26 through the clamp 18, which in turn moves the filter screen plate 16 smoothly out of the drying chamber 6 along the guide rod 20 until it is completely between the screen changing table 11 and the placement table 10. The operator places the new filter screen plate 16 on the push plate 14 of the screen changing table 11 and starts the material changing motor 15. The material changing motor 15 drives the lead screw 22 to rotate. The lead screw 22 drives the slider 12 and the baffle 13 to move. The baffle 13 pushes the push plate 14 to move the filter screen plate 16 to the position aligned with the inlet of the drying chamber 6. At the same time, the original filter screen plate 16 is pushed along the auxiliary plate and the support plate 2727 to the top of the placement table 10. Then, the electric push rod 17 can be used to push the new filter screen plate 16 into the predetermined position inside the drying chamber 6. If it is necessary to clean or repair the inside of the drying chamber 6, the inspection door 7 can be opened for operation.
