After the collecting box 33 moves and drives the side sealing plate 34 to move into the side groove 36, the fixing member 35 is used to fix the side sealing plate 34 and the fixing box 31. Subsequently, the large-volume colloidal precipitates discharged by the cleaning and impurity removal mechanism 2 fall into the collecting box 33 for collection, which facilitates the collection of the discharged large-volume colloidal precipitates and prevents the discharged large-volume colloidal precipitates from falling onto the sand filter tank 1 or the surrounding environment, causing the surrounding environment to be wet and slippery.

The movement of the tightening screw 354 drives the tightening plate 352 to move into the L-shaped rod 351. The tightening plate 352 can be used to tighten and fix the L-shaped rod 351, thereby ensuring the stability of the collection box 33.

[0028] Specifically, a guide plate 32 is connected to the inner wall of the fixed box 31 and located above the collecting box 33. The guide plate 32 is arranged in an inclined state.

The tightening plate 352 can be used to tighten and fix the L-shaped rod 351, thereby ensuring the stability of the collection box 33. The silver-plated electroplating wastewater after precipitation treatment is injected into the sand filter tank 1 Under the action of the filtering mechanism 5, the large colloidal precipitates in the injected wastewater remain inside the filtering mechanism 5, and the wastewater is discharged through the outlet pipe 4 to participate in subsequent treatment operations, so as to facilitate the subsequent reuse of the wastewater. The cleaning and impurity removal mechanism 2 is then used to discharge the large colloidal precipitates inside the filtering mechanism 5, and the discharged large colloidal precipitates slide along the guide plate 32 into the collection box 33, which is convenient for collecting the discharged large colloidal precipitates and preventing the discharged large colloidal precipitates from falling onto the sand filter tank 1 or the surrounding environment, causing the surrounding environment to be wet and slippery.

[0034] By adopting the above technical solution, the pushing rod is moved along the pushing mouth, and the movement of the pushing rod drives the limit rod to move into the groove. The limit rod moves to squeeze the connecting spring, and then the installation frame 64 is placed into the installation groove 63. The pushing rod is released, and the connecting spring loses the external force and returns to its original appearance, driving the limit rod to move and be inserted into the limit groove.

The air inside the delivery pipe is extracted through the suction pipe, so that the suction component can absorb the colloidal sediment with a large volume on the top of the quartz sand layer, and then the colloidal sediment is discharged outward through the delivery pipe, the suction pipe and the sewage pipe. The rotation drive source is started to drive the meshing transmission between the first flat gear and the second flat gear to rotate the delivery pipe. When the delivery pipe rotates, the sewage suction pipe is driven to rotate along the axis of the delivery pipe.

At this time, the pull rod is driven to move by the elastic part, and the first and second sliding rods on the pull rod respectively pull the first and second flipping parts to flip, so that the first and second flipping parts flip in opposite directions, and under the action of centrifugal force, the flipped colloidal sediment is concentrated and thrown onto the moving track of the sewage suction pipe.

[0037] The structure and principle of the filtering mechanism 5 composed of a support net and a quartz sand layer in the utility model have been disclosed in an electroplating wastewater reuse device disclosed in Chinese patent application No. 202410247200.0. Its working principle is: the interior of the sand filter tank 1 is connected to a support net, and a quartz sand layer is arranged above the support net. The quartz sand is supported by the support net. After the wastewater after precipitation treatment is injected into the interior of the sand filter tank 1, the quartz sand layer can filter the wastewater. The wastewater falls into the bottom of the sand filter tank 1 through the pores on the support net, and the large colloidal precipitates in the wastewater remain in the quartz sand layer.

[0038] The working principle and usage process of the present invention are as follows: after the side sealing plate 34 is moved and stored in the side groove 36 by holding the L-shaped rod 351 by hand, the side sealing plate 34 moves and drives the collection box 33 to move and store in the fixed box 31, and then the tightening screw 354 is rotated to make it rotate along the end plate 353, and the tightening screw 354 moves and drives the tightening plate 352 to move into the L-shaped rod 351. The tightening plate 352 can be used to tighten and fix the L-shaped rod 351, thereby ensuring the stability of the collection box 33. The pushing rod is moved along the pushing port, and the pushing rod moves to drive the limiting rod to move and store in the groove. The limiting rod moves to squeeze the connecting spring, and then after the installation frame 64 is placed in the installation groove 63, the pushing rod is released, and the connecting spring loses the external force and returns to its original state, driving the limiting rod to move and be inserted into the limiting groove, so that the transparent plate 61 can be installed into the observation port 62. The silver electroplating wastewater after precipitation treatment is injected into the sand filter tank 1. Under the action of the filtering mechanism 5, the large colloidal precipitates in the injected wastewater remain in the filtering mechanism 5. The wastewater is discharged through the outlet pipe 4 to participate in subsequent treatment operations, so as to facilitate the subsequent reuse of the wastewater. The cleaning and impurity removal mechanism 2 is then used to discharge the large colloidal precipitates in the filtering mechanism 5, and the discharged large colloidal precipitates slide along the guide plate 32 into the collecting box 33, so as to facilitate the collection of the discharged large colloidal precipitates and avoid the discharged large colloidal precipitates falling onto the sand filter tank 1 or the surrounding environment, causing the surrounding environment to be wet and slippery. In the process of using the cleaning and impurity removal mechanism 2 to discharge the large colloidal precipitates in the filtering mechanism 5, the operator can observe the situation of the discharged colloidal precipitates through the transparent plate 61 to judge whether the large precipitates on the upper layer of the filtering mechanism 5 are completely cleaned.
