[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-Figure 5 , an electroplating sludge treatment pool, including a treatment pool barrel 1, a cover plate 2 is threadedly installed on the upper end of the treatment pool barrel 1, and a sealing gasket is provided on the cover plate 2, which is tightly connected to the treatment pool barrel 1 through a thread to prevent gas or liquid leakage during the treatment process, a driving motor 3 is fixedly installed on the upper end of the cover plate 2, and a rotating shaft 15 is fixedly installed on the output end of the driving motor 3. A stirring rod 16 is fixedly installed on the circumference of the rotating shaft 15. The stirring rod 16 is evenly distributed on the circumference of the rotating shaft 15 and adopts a spiral design or a paddle type to optimize the stirring effect and promote the full mixing of the sludge and the treatment liquid. A feed pipe 7 is fixedly installed on one side of the upper end of the cover plate 2, and an extrusion barrel 4 is fixedly installed on the upper end of the feed pipe 7. A feed hopper 11 is provided on the top of the extrusion barrel 4, and a water collecting part 9 is connected to the bottom. A threaded rod 1 driven by a stepping motor 12 is provided in the middle. 4 and a water leakage plate 13 to achieve preliminary dehydration of the sludge. A stepper motor 12 is fixedly installed on one side of the extrusion cylinder 4, and a threaded rod 14 is fixedly installed on the output end of the stepper motor 12. The threaded rod 14 is threadedly connected to the water leakage plate 13 on the circumference of the threaded rod 14. The water leakage plate 13 pushes the water leakage plate 13 to move left and right by rotating the threaded rod 14, and adjusts the extrusion gap to achieve continuous extrusion and dehydration of the sludge. A chute 6 is provided on the other side of the extrusion cylinder 4, and a baffle plate 17 is slidably installed at the bottom of the extrusion cylinder 4. The baffle plate 17 is controlled by the handle 5 and is used to temporarily block the flow of materials in the extrusion cylinder 4 for easy maintenance or adjustment. A handle 5 is fixedly installed on one side of the baffle plate 17, a dispersion part 8 is fixedly installed on the inner wall of the treatment tank cylinder 1, a water collecting part 9 is fixedly installed at the bottom of the extrusion cylinder 4, and a feed hopper 11 is fixedly installed on the upper end of the extrusion cylinder 4.

[0020] When in use, correctly connect the power cords of the drive motor 3 and the stepper motor 12 to the power supply, slowly add the electroplating sludge into the extrusion barrel 4 through the feed hopper 11, pay attention to controlling the feeding speed to avoid clogging, start the stepper motor 12, the motor drives the threaded rod 14 to rotate, pushes the leakage plate 13 to move left and right in the extrusion barrel 4, adjusts the extrusion gap, performs preliminary dehydration on the sludge, observes the dehydration effect, and adjusts the speed of the stepper motor 12 and the position of the leakage plate 13 in time. After the sludge after preliminary dehydration enters the treatment tank barrel 1 through the feed pipe 7, start the drive motor 3, and the motor drives the rotating shaft 15 to rotate The stirring rod 16 is driven by the stepper motor 12 to stir the sludge and the treatment liquid. The spiral or paddle design of the stirring rod 16 helps to optimize the stirring effect and promote the full mixing of the sludge and the treatment liquid. The extrusion cylinder 4 driven by the stepper motor 12 realizes the efficient initial dehydration of the sludge, reduces the difficulty and cost of subsequent treatment, and improves the treatment efficiency. The stirring device adopts a spiral or paddle design to ensure that the sludge and the treatment liquid are fully mixed in the treatment tank 1, thereby improving the treatment effect. The use of the dispersion element 8 can vibrate with the fluid fluctuation during the stirring process, enhance the mixing effect, and promote the decomposition and reaction of the sludge.

[0021] like Figure 3 or Figure 4 As shown, the dispersing member 8 is fixedly mounted on the inner wall of the treatment tank barrel 1 with a fixed plate 801, a movable plate 802, a U-shaped connecting block 803, a spring 804 and a T-shaped guide column 805. The movable plate 802 is slidably mounted inside the fixed plate 801, and the T-shaped guide column 805 is fixedly mounted on the top of the movable plate 802. The U-shaped connecting block 803 is fixedly mounted on the upper end of the fixed plate 801, and the U-shaped connecting block 803 is slidably connected to the T-shaped guide column 805. One end of the spring 804 is fixedly mounted on the bottom inner side of the U-shaped connecting block 803, and the other end is fixedly connected to the movable plate 802. During the above-mentioned use, when the stirring device in the treatment tank barrel 1 starts to work, the rotation of the stirring rod 16 will drive the flow of the treatment liquid and sludge. As the stirring progresses, The flow of the treatment liquid and the sludge will impact the movable plate 802 of the dispersion member 8. Since there is a gap between the movable plate 802 and the fixed plate 801 and it is supported by the spring 804, the movable plate 802 will vibrate under the impact of the fluid. The vibration of the movable plate 802 will further promote the mixing of the treatment liquid and the sludge, so that the sludge particles are more evenly dispersed in the treatment liquid, thereby accelerating the chemical reaction rate and improving the treatment efficiency. The vibration effect of the dispersion member 8 can significantly increase the contact area and frequency between the treatment liquid and the sludge, thereby accelerating the mixing speed and improving the treatment efficiency. The uniform mixing helps the harmful substances in the sludge to react more fully with the treatment liquid, improve the treatment effect, and reduce the difficulty and cost of subsequent treatment.

[0022] like Figure 2As shown, the water collecting part 9 is fixedly installed with the water collecting bucket 901, the water pipe 902, the water storage tank 903 and the water pumping pipe 904 at the bottom of the extrusion cylinder 4. One end of the water pipe 902 is fixedly installed with the bottom of the water collecting bucket 901, and the other end is fixedly installed with the top of the water storage tank 903. The water pumping pipe 904 is fixedly installed with one side of the water storage tank 903. During the above-mentioned use, when the electroplating sludge is squeezed and dehydrated in the extrusion cylinder 4, the wastewater generated will flow into the water collecting bucket 901. As the wastewater accumulates, the water level in the water collecting bucket 901 gradually rises. When the water level reaches a certain level, the wastewater will be discharged. The wastewater automatically flows into the water storage tank 903 through the water pipe 902 and is stored. When the wastewater in the water storage tank 903 accumulates to a certain amount, the wastewater can be pumped out through the pumping pipe 904 and sent to the wastewater treatment system for treatment, or directly discharged into drainage facilities that meet environmental protection requirements. The design of the water collecting part 9 realizes the automatic collection and storage of wastewater, reduces the tediousness and labor intensity of manual operation, and improves work efficiency. The sealed connection between the water collecting bucket 901 and the water pipe 902 effectively prevents the leakage and spread of wastewater during the treatment process, thereby protecting the cleanliness of the environment and equipment.

[0023] like Figure 2 As shown, a rubber strip is fixedly installed at the place where the water leakage plate 13 and the extrusion cylinder 4 abut each other. During the above-mentioned use, the installation of the rubber strip effectively prevents wastewater and sludge from leaking out from the gap between the water leakage plate 13 and the extrusion cylinder 4 during the extrusion process, thereby maintaining the cleanliness of the equipment and the hygiene of the environment. Due to the sealing effect of the rubber strip, the pressure in the extrusion cylinder 4 can act more concentratedly on the sludge, thereby improving the dehydration efficiency and reducing the amount of wastewater generated.

[0024] like Figure 1 or Figure 2 As shown, a support plate 10 is fixedly installed at the bottom of one side of the extrusion cylinder 4, and the bottom end of the support plate 10 is fixedly installed to the bottom surface. During the above-mentioned use, the installation of the support plate 10 significantly enhances the stability of the extrusion cylinder 4, reduces the displacement and shaking caused by vibration or impact, helps to ensure the smooth progress of the extrusion process, and improves the processing efficiency and the quality of the finished product.
