Description

Technical Field

[0001] The invention relates to the technical field of electrophoresis wastewater treatment, and in particular to a vehicle frame electrophoresis wastewater discharge treatment system. Background Art

[0002] Electrophoresis refers to the phenomenon that charged particles move toward the electrode with opposite electrical properties under the action of an electric field. The technology that uses the different moving speeds of charged particles in an electric field to achieve separation is called electrophoresis technology. A large amount of wastewater will be generated during the electrophoresis processing of the frame. In order to reduce the pollution of wastewater to the environment, it is necessary to purify the wastewater.

[0003] Chinese patent CN115571960A discloses an electrophoresis wastewater treatment system, including a base and a cover, a main box body is fixed on the upper end surface of the base, and a sedimentation chamber with an opening upward is arranged in the main box body. The invention rotates the material distribution plate so that the electrophoresis wastewater and the sediment in the sedimentation chamber enter the material distribution chamber in batches, and then enter the filter chamber through the lower connecting chamber, and the sediment in the wastewater is filtered out by using a U-shaped filter screen, and the supernatant is discharged through the drain port and the drain chamber. The sediment is rotated to the left side of the spherical brush by the rotation of the filter plate, and the sediment is swept into the storage box by the rotating spherical brush, and then the sediment is removed by the addition of the filter plate. The precipitate is dried under the heating of the heat pipe for subsequent treatment, while preventing the precipitate from accumulating on the U-shaped filter, ensuring the filtering effect of the U-shaped filter. The multiple filtration allows the wastewater in the sedimentation chamber to be continuously precipitated, thereby improving the treatment efficiency of the electrophoretic wastewater. The above-mentioned related technologies have the following defects: In the existing technology of adding flocculants for precipitation treatment, the generated flocculants need to be precipitated to the bottom for collection, which makes it inconvenient to separate the purified wastewater from the thicker deposited flocculants. More flocculants are precipitated at the bottom, which is easy to cause blockage in the filtration. Therefore, a frame electrophoretic wastewater discharge treatment system is proposed.

When the interlayer isolation plate 43 rotates to a horizontal state, the end of the interlayer isolation plate 43 away from the outer cylinder 41 contacts the inner wall of the wastewater treatment tank 1. When the lowest interlayer isolation plate 43 rotates to a horizontal state, the bottom surface of the interlayer isolation plate 43 contacts the inner bottom wall of the wastewater treatment tank 1 to ensure that no wastewater is below the lowest interlayer isolation plate 43, and to ensure that the generated sediment is located above the interlayer isolation plate 43.

[0034] A liquid supply box 3 is installed on the outside of the wastewater treatment box 1, and the flocculating agent is placed in the liquid supply box 3. The liquid supply box 3 and the sedimentation collection box 2 are located on the same side of the wastewater treatment box 1. A gas supply box 5 is installed on the outside of the wastewater treatment box 1 away from the sedimentation collection box 2. The gas supply box 5 is installed with an air pump and a pressure relief valve.

[0035] The liquid transfer structure 6 includes a liquid through tube 61, an inner ring plugging plate 62 and an outer ring plugging plate 63.

[0036] The gas transfer structure 7 includes a ventilation pipe 71, an inner ring twist plate 72 and an outer ring fixing plate 73. The inner ring twist plate 72 is fixedly sleeved on the outer surface of the ventilation pipe 71. The other end of the ventilation pipe 71 is fixed to the adjacent outer cylinder 41. The ventilation pipe 71 is connected to the gas cavity 46. The outer ring surface of the inner ring twist plate 72 is in sliding contact with the inner ring surface of the outer ring fixing plate 73. The outer ring fixing plate 73 is fixed to the outer surface of the wastewater treatment box 1. A gas pipe 74 is fixedly passed through the outer ring surface of the outer ring fixing plate 73. The other end of the gas pipe 74 is connected and installed with the gas supply box 5. When the interlayer isolation plate 43 rotates to a horizontal state, the ventilation pipe 71 rotates to be connected with the gas pipe 74. The gas supply box 5 inflates the gas cavity 46 through the gas pipe 74 and the ventilation pipe 71.

[0037] The interior of the interlayer isolation plate 43 is connected with the interior of the liquid cavity 45. A liquid outlet 8 is provided on the inner top wall of the interlayer isolation plate 43. A conical plug 9 is slidably inserted into the interior of the liquid outlet 8. The conical plug 9 is elastically connected to the inner wall of the interlayer isolation plate 43. The conical plug 9 has a tendency to block the liquid outlet 8 under the elastic connection with the interlayer isolation plate 43. The front and rear ends of the upper surface of the interlayer isolation plate 43 are bent upward. A pushing structure 10 is slidably fitted on the upper side of the interlayer isolation plate 43. An elastic telescopic soft cylinder 11 is installed at one end of the pushing structure 10 close to the adjacent outer cylinder. The other end of the elastic telescopic soft cylinder 11 is connected and installed with the adjacent outer cylinder 41. The elastic telescopic soft cylinder 11 is connected to the gas cavity 46.

[0038] The pushing structure 10 includes a moving bar 101 and a one-way push plate 102. The lower end of the moving bar 101 is an L-shaped groove structure. The upper end of the one-way push plate 102 is located inside the L-shaped groove structure of the moving bar 101. The upper end of the one-way push plate 102 is elastically rotatably connected to the moving bar 101. The moving bar 101 is slidably matched with the upper surface of the sandwich isolation plate 43. The moving bar 101 is fixed to the elastic telescopic soft cylinder 11. The conical plug 9 is located on the sandwich isolation plate 43. The upper end is conical, and the lower end of the conical plug 9 is cylindrical and matches the liquid outlet 8. The distance between the lower end of the one-way push plate 102 and the upper end of the adjacent conical plug 9 is greater than the thickness of the inner top wall of the sandwich isolation plate 43 and the upper surface of the sandwich isolation plate 43. The lower end of the one-way push plate 102 is a plurality of groove-shaped structures. The groove-shaped structures of the one-way push plate 102 are staggered with the lateral position of the conical plug 9. When the sandwich isolation plate 43 is rotated to a horizontal state, the gas The cavity 46 inflates the elastic telescopic soft cylinder 11 connected to it, and the elastic telescopic soft cylinder 11 gradually stretches with the filling of gas, pushing the moving strip 101 and the one-way push plate 102 gradually away from the outer cylinder 41. When the one-way push plate 102 applies thrust to the conical plug 9 during its movement, the conical plug 9 retracts into the inner part of the sandwich isolation plate 43, so that the liquid in the sandwich isolation plate 43 can be added to the wastewater from the liquid outlet 8, and the corresponding flocculation agents can be added at the corresponding heights according to the height of the liquid level inside the wastewater treatment tank 1, effectively preventing excessive flocculation agents, and at the same time, the wastewater can be evenly contacted with the added flocculation agents. After the sandwich isolation plate 43 rotates to the inclined state, the vent pipe 71 is misaligned with the gas pipe 74, and at the same time, the vent pipe 71 is connected to the external space, so that the elastic telescopic soft cylinder 11 contracts under its own elasticity, and the moving strip 101 and the one-way push plate 102 move downward under gravity and the contraction and stretching of the elastic telescopic soft cylinder 11.

[0039] A liquid level sensing wireless controller 12 is fixedly inserted inside the wastewater treatment box 1, and a toothed plate 13 is arranged on the side of the wastewater treatment box 1 away from the sedimentation collection box 2. A threaded shaft 14 is threaded through the upper surface of the toothed plate 13, and an induction control motor 15 is installed on the upper end of the threaded shaft 14. The induction control motor 15 is connected to the gas supply box 5. The liquid level sensing wireless controller 12 controls the induction control motor 15 to rotate a corresponding angle according to the liquid level, and drives the toothed plate 13 to move to be flush with the liquid surface. The liquid passing pipe 61, the ventilation pipe 71 and the interlayer isolation plate 43 connected to the same outer cylinder 41 are arranged in parallel, and the two interlayer isolation plates 43 connected to the two outer cylinders 41 located on the same horizontal plane are arranged in a V shape. When the toothed plate 13 moves upward, it drives the corresponding outer cylinder 41 to rotate a certain angle by meshing with the gear 47 passed through, so that the corresponding interlayer isolation plate 43 rotates to a horizontal state, so that the two interlayer isolation plates 43 on the same horizontal plane can cooperate and contact with the inner wall of the wastewater treatment box 1.

[0040] The working principle is as follows: when purifying wastewater, the lower end of the wastewater treatment tank 1 is blocked, and wastewater is added to the wastewater treatment tank 1. The liquid level sensing wireless controller 12 detects the liquid level inside the wastewater treatment tank 1, controls the sensing control motor 15 to drive the threaded shaft 14 to rotate a corresponding angle, and the toothed plate 13 moves to be flush with the liquid level inside the wastewater treatment tank 1 by meshing with the threaded shaft 14. The toothed plate 13 drives the corresponding interlayer isolation plate 43 to rotate to a horizontal state by meshing with the passing gear 47 during the upward movement, so that the interlayer isolation plates 43 below the liquid level inside the wastewater treatment tank 1 are all in a horizontal state, and the interior of the wastewater treatment tank 1 below the liquid level is divided into multiple spaces, and the wastewater is mixed with the added flocculation agent to produce flocculent precipitation. During sedimentation, the floccules in different spaces are respectively precipitated onto the upper surfaces of the corresponding interlayer isolation plates 43, and the floccules are precipitated in layers. When the purified wastewater is discharged from the lower end of the wastewater treatment tank 1, the floccules are respectively blocked above the corresponding interlayer isolation plates 43. As the liquid level decreases, the liquid level sensing wireless controller 12 detects the drop in the liquid level, controls the reverse rotation of the threaded shaft 14 to drive the toothed plate 13 to move downward, and the toothed plate 13 is reset downward by meshing with the gear 47 to drive the corresponding interlayer isolation plate 43 to return to an inclined state, so that the open structure of the outer cylinder 41 coincides with the open structure of the inner cylinder 42, so that the sediment on the interlayer isolation plate 43 slides downward under gravity, and then falls into the inner cylinder 42 through the openings of the outer cylinder 41 and the inner cylinder 42.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
