Description

Technical Field

[0001] The invention relates to the technical field of electrophoresis wastewater treatment, in particular to an electrophoresis wastewater treatment device with multi-stage treatment. Background Art

[0002] Electrophoretic coating is one of the steps in the surface treatment of spare parts in the automotive, household appliances and electronics industries. Electrophoretic coating can produce a coating on the surface of spare parts, thereby protecting the spare parts from corrosion. Electrophoretic wastewater is generated during the electrophoretic coating process. Therefore, electrophoretic wastewater treatment equipment is currently used to treat electrophoretic wastewater to avoid environmental pollution.

[0003] The patent name disclosed in the prior art with application number "CN202410777346.6" is "A treatment process for cathode electrophoretic coating wastewater". When the pressure plate moves downward, the pressure plate will pull the fixed pulley to move, the fixed pulley drives the winding wheel to rotate, the winding wheel drives the connecting shaft to rotate, and during the rotation of the connecting shaft, the two coil springs will not continuously accumulate power, the connecting shaft drives the bevel gear three to rotate, the bevel gear three drives the bevel gear four to rotate, the bevel gear four drives the cleaning shaft to rotate, the cleaning shaft drives the cleaning rod to rotate, and the cleaning rod is on The filter screen can be cleaned by a plurality of cleaning strips, which can clear the mesh of the filter screen, so that the filtering effect of the filter screen is always in a relatively stable state, and the slow flow rate caused by the blockage of the mesh of the filter screen is effectively avoided; when the pressure plate moves upward, the connecting shaft rotates in the opposite direction under the action of the winding spring, so that the winding wheel rotates in the opposite direction, and the wiring harness will return to its original state, which is convenient for the pressure plate to continue to drive the winding wheel to rotate next time, effectively improving the coordination degree of the device, with high functionality and strong practicality;

[0004] The patent name disclosed in the prior art with application number "CN201922256366.6" is "A wastewater treatment device for electrophoresis processing of metal parts", which discloses that the wastewater for electrophoresis processing of metal parts is introduced into the interior of the particle filtering mechanism. Since a groove is opened in the middle of the sedimentation tank, and both sides of the groove are welded and connected to the filter plate, the particles filtered by the filter plate enter the interior of the sedimentation tank, and the spiral blade is driven by the first motor to rotate, so that the spiral blade pushes the wastewater particles inside the sedimentation tank to one end of the sedimentation tank, and is collected by the sludge storage tank. The wastewater pre-treated by the filter plate enters the interior of the chemical treatment tank, and after chemical treatment in the chemical treatment tank, it is introduced into the interior of the reclaimed water purification mechanism through a water pump, and the wastewater is filtered through the filter membrane. At the same time, the second motor drives the connecting shaft to rotate. Since the connecting shaft and the top of the rotating shaft are connected by welding, the connecting shaft drives the rotating shaft to rotate, and then the connecting rod drives the brush to rotate. Since one end of the brush is completely in contact with the inner surface of the filter membrane, the brush cleans the inner surface of the filter membrane.

[0005] The electrophoresis sewage treatment device in the above prior art only has one filter plate when treating sewage, so that only the sewage can be initially filtered and the sewage cannot be filtered in multiple stages, which results in poor sewage filtering effect and affects subsequent treatment work.

The specific contents are as follows:

[0033] (1) The large suspended solids in the electrophoresis wastewater can be initially filtered through the grid body, and the electrophoresis wastewater with precipitation can be filtered again through the protective filter net at a later stage, thereby facilitating multi-stage filtration treatment of the electrophoresis wastewater, thus improving the filtration treatment effect of the electrophoresis wastewater, facilitating the subsequent treatment of the electrophoresis wastewater, and thus improving the treatment effect of the electrophoresis wastewater;

When the first adsorption block and the second adsorption block are not on the same vertical plane, the reset rod and the upper support plate are automatically driven to move upward by the stored force of the connecting spring. Therefore, when the rotating rod rotates, the upper support plate reciprocatingly presses and stretches the protective filter, and then the protective filter is shaken, thereby preventing sediment from sticking to the outside of the protective filter, thereby facilitating the use of the protective filter;

[0035] Furthermore, by setting the first piston body, when the reset rod drives the first piston body to descend, the first piston body will push the gas in the reset column, so that the gas in the reset column enters the fixed sleeve, and then the second piston body in the fixed sleeve is pushed to move outward, and the second piston body drives the arc-shaped expansion plate to move outward, so that the expansion plate can expand the surrounding areas of the pressed protective filter screen outward, thereby avoiding affecting the sewage from entering the guide pipe from the protective filter screen;

[0036] (3) When the medicine tube rotates, the connecting rod drives the grille body to rotate together, so that the grille body can filter while rotating. In this way, various positions of the grille body can be used. At the same time, through the rotation of the grille body, the scraping mechanism with an arc-shaped structure on one side can scrape the impurities on the outer side of the grille body well, so that the impurities fall into the slag storage tank, which is convenient for later cleaning, and no additional power source is required.

[0053] The interior of the reset column 21 is a hollow structure, and a connecting spring 20 is installed inside the reset column 21. The upper end of the connecting spring 20 is connected to the reset rod 211, and the upper end of the reset rod 211 is connected to the upper support plate 18. The three groups of delivery pump bodies 10 sequentially transport the sewage to the sedimentation treatment chamber 24, the acid-base adjustment chamber 8, the flotation treatment chamber 9 and the adsorption treatment chamber 11 for multi-stage treatment. A slag storage groove 201 is provided on the rear side of the bottom surface of the preliminary treatment chamber 2, and the slag storage groove 201 is connected to the slag discharge port 7 on the rear side of the outer box body 1. The rear side of the grille body 16 is fitted with a scraping mechanism 17 installed inside the preliminary treatment chamber 2, and the scraping mechanism 17 is arranged in an arc shape at one end close to the grille body 16. A residue storage groove 201 is provided at the lower left side of the scraping mechanism 17, the interior of the lower medicine pipe 4 is hollow, and through grooves 401 with an arc-shaped structure are evenly spaced on the upper outer side of the lower medicine pipe 4. The through grooves 401 are arranged in the temporary storage box 3, and the height of the through grooves 401 is less than the height of the temporary storage box 3. Through holes are evenly spaced above the guide pipe 14, and the height of the guide pipe 14 with through holes is less than the height of the protective filter screen 13. The inner side of the grid body 16 is connected to the lower medicine pipe 4 through a connecting rod 161; the bottom surface of the preliminary processing chamber 2 is open, and the inner diameter of the bottom surface of the preliminary processing chamber 2 is smaller than the inner diameter of the grid body 16; the lowest point of the lower medicine pipe 4 is lower than the lowest point of the grid body 16.

[0054] First, the entire electrophoretic wastewater treatment device is moved into the working area. After arriving at the working area, the entire electrophoretic wastewater treatment device can be used. First, the electrophoretic wastewater from the outside is conveyed into the preliminary treatment chamber 2 through the water inlet pipe on the left side of the preliminary treatment chamber 2 through the conveying mechanism. At this time, the wastewater is first filtered through the annular grid body 16 in the preliminary treatment chamber 2, and then the filtered wastewater flows into the sedimentation treatment chamber 24 through the bottom end of the grid body 16, and impurities remain on the outside of the grid body 16.

[0055] Then, the chemical precipitant is transported to the temporary storage box 3, and then the chemical precipitant enters the medicine tube 4 with a hollow structure inside through the through groove 401, and then the chemical precipitant falls into the precipitation treatment chamber 24 through the medicine tube 4. At this time, the chemical precipitant reacts with the electrophoresis wastewater, so that the metal ions and suspended matter in the electrophoresis wastewater are precipitated. At the same time, the upper end of the medicine tube 4 can be connected to an external motor through a coupling, and the motor drives the medicine tube 4 and the rotating rod 15 to rotate. At this time, the rotation of the rotating rod 15 can make the chemical precipitant and The electrophoretic wastewater is well contacted and reacted, and at the same time, the medicine tube 4 will drive the grid body 16 to rotate through the connecting rod 161 when rotating. At this time, the grid body 16 rotates in the preliminary treatment chamber 2, so that the fixed scraping mechanism 17 can well scrape the impurities on the outer side of the grid body 16, so that the impurities fall into the slag storage tank 201, and the impurities can be discharged later by opening the slag discharge port 7, thereby the impurities on the surface of the grid body 16 can be well cleaned, so that the grid body 16 can be well filtered for preliminary filtering of the electrophoretic wastewater.

[0056] After a period of time, the delivery pump body 10 below the sedimentation treatment chamber 24 is started, and then the sewage in the sedimentation treatment chamber 24 is filtered through the protective filter screen 13, and then enters the guide tube 14 through the hole at the upper end of the guide tube 14, and then the sewage in the sedimentation treatment chamber 24 is transported to the acid-base adjustment chamber 8 through the delivery pump body 10. At this time, part of the sediment is accumulated in the sedimentation treatment chamber 24, and the other part of the sediment is adhered to the outside of the protective filter screen 13. At a later stage, the sediment in the sedimentation treatment chamber 24 can be cleaned by opening the observation door on the left side of the outer box body 1, and then by sending the acid-base Hydrochloric acid or sodium hydroxide is added to the adjustment chamber 8 to adjust the pH value, and then the delivery pump body 10 below the acid-base adjustment chamber 8 is started, so that the sewage in the acid-base adjustment chamber 8 is transported to the flotation treatment chamber 9 through the delivery pump body 10, and then tiny bubbles are injected into the sewage in the flotation treatment chamber 9 through the dissolved air release mechanism 6. At this time, the suspended matter and grease in the sewage adhere to the bubbles, and the buoyancy increases and floats to the water surface to form scum. Then the staff can open the observation door on the outer box body 1, and then take the scraping tool from the outside to remove the scum. Since this part is a prior art, it will not be introduced in detail here.

[0057] Then, as shown above, the delivery pump body 10 is started again to deliver the sewage in the flotation treatment chamber 9 to the adsorption treatment chamber 11 through the delivery pump body 10, and then the organic matter, residual metal ions and odorous substances in the sewage can be further removed through the activated carbon adsorption plate 12 in the adsorption treatment chamber 11, thereby improving the water quality and avoiding subsequent environmental pollution. As a result, the entire electrophoretic sewage treatment device can perform multi-stage treatment on the electrophoretic sewage to meet different usage requirements.

[0058] Embodiment 2: The multi-stage electrophoresis wastewater treatment device in this embodiment can further clean the impurities on the surface of the protective filter 13 to prevent the impurities from adhering to the outside of the protective filter 13 and affecting the subsequent filtering work. The specific structure is shown in the attached Figure 8-Figure 11 As shown, the rotating rod 15 is arranged in a "7"-shaped structure, and a first adsorption block 151 is installed on the upper and lower surfaces of the rotating rod 15; a second adsorption block 181 is symmetrically installed above the upper support plate 18, and the upper support plate 18 is arranged in a conical structure. A lower medicine tube 4 is arranged above the upper support plate 18, and the second adsorption block 181 and the first adsorption block 151 are magnet blocks with the same magnetic poles. The upper support plate 18 forms a reciprocating lifting structure through the first adsorption block 151. On the basis of Example 1, when the rotating rod 15 rotates, the rotating rod 15 will drive the first adsorption block 151 to rotate. When the first adsorption block 151 rotates to the same vertical plane as the second adsorption block 181, at this time, since the first adsorption block 151 and the second adsorption block 181 are made of magnet blocks with the same magnetic poles, a repulsive force is generated between the first adsorption block 151 and the second adsorption block 181. At this time, the second adsorption block 181 will drive the upper support plate 18 to move downward. When the first adsorption block 151 rotates to a point where it is not on the same vertical plane as the second adsorption block 181, the force stored in the connecting spring 20 will automatically drive the reset rod 211 to move upward and reset, and then the reset rod 211 drives the upper support plate 18 to move upward and reset, and at this time the upper support plate 18 pulls the protective filter screen 13, and the operation is repeated so that the upper support plate 18 reciprocates to squeeze and pull the protective filter screen 13 downward and upward, thereby allowing the upper support plate 18 to shake the protective filter screen 13 up and down, thereby facilitating the shaking off of impurities adhered to the outer surface of the protective filter screen 13, and then the protective filter screen 13 can be cleaned without the need for an additional power source, so that the protective filter screen 13 can be used well.

[0059] Embodiment 3: The multi-stage electrophoresis wastewater treatment device in this embodiment, when cleaning the impurities on the surface of the protective filter 13, will not affect the flow of wastewater through the protective filter 13 into the guide pipe 14. The specific structure is shown in the attached Figure 10-12 As shown, a first piston body 212 is installed on the outer side of the middle part of the reset rod 211, and the outer side surface of the first piston body 212 is in close contact with the inner wall of the reset column 21. A fixed sleeve 23 is installed through the outer side of the lower part of the reset column 21, and the second piston body 231 is slidably connected inside the fixed sleeve 23. An expansion plate 22 is installed on the outer end of the second piston body 231. The expansion plate 22 is arranged in an arc-shaped rotating structure. The expansion plate 22 is arranged on the inner side of the protective filter screen 13, and the highest point of the expansion plate 22 is lower than the highest point of the guide tube 14. On the basis of the second embodiment, when the lower end of the reset rod 211 enters the reset column 21 to squeeze and store force on the connecting spring 20, the upper support plate 18 squeezes the protective filter screen 13 downward. At the same time, the reset rod 211 drives the outer first piston body 212 to enter the reset column 21. The outer side surface of the first piston body 212 is fitted with the inner wall of the reset column 21, so that when the first piston body 212 moves downward, the gas in the reset column 21 will be squeezed into the fixed sleeve 23. At this time, the gas in the fixed sleeve 23 will automatically push the second piston body 231 to move outward. At this time, the outer end of the second piston body 231 drives the arc-shaped expansion plate 22 to move outward. At this time, the expansion plate 22 can expand the protective filter screen 13 that is squeezed downward outward, thereby preventing the protective filter screen 13 from being squeezed downward and affecting the sewage from entering the protective filter screen 13. Such repeated operations can not only expand the protective filter screen 13 well for filtering work, but also further push the impurities on the outside of the protective filter screen 13, so that the protective filter screen 13 can be used well, thereby completing a series of tasks.
