Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a wastewater filtration and purification device for ink production. Background Art

[0002] The wastewater generated during the ink production process mainly comes from equipment cleaning, raw material residues, and reaction by-products, and contains harmful substances such as dyes, resins, solvents, and heavy metal ions. It has the characteristics of high chromaticity, high COD (chemical oxygen demand), and being difficult to degrade. The wastewater has a complex composition. If directly discharged, it will seriously pollute water bodies and affect the ecological environment. Therefore, it is necessary to use a wastewater filtration and purification device for ink production to filter and purify the wastewater, so as to remove harmful substances and reduce the pollutant concentration, ensuring that the wastewater meets the discharge standards.

[0003] When the existing wastewater filtration and purification device for ink production filters wastewater, it usually uses a filter screen to filter impurities in the wastewater. However, the existing filter screens are usually fixedly installed inside the filtration and purification device, which is not convenient for quickly cleaning the blocked impurities on the filter screen, thereby affecting the wastewater filtration effect. Moreover, during the process of purifying wastewater, the medicament is usually directly poured into the wastewater, and the medicament will directly precipitate at the bottom of the wastewater, and the wastewater's absorption effect of the medicament is not good, resulting in poor filtration and purification effects on the wastewater of ink production. Therefore, based on the actual usage situation, we have improved the above existing technology. Summary of the Invention

[0025] Embodiment 1:

[0026] Please refer to Figures 1-6 , the present invention provides a technical solution: a wastewater filtration and purification device for ink production, including a wastewater treatment tank 1 and two groups of support chassis 2. A top cover 3 is provided at the top of the wastewater treatment tank 1, and a wastewater pipe 4 communicating with the inner cavity of the wastewater treatment tank 1 is provided on the top cover 3. Four groups of connecting rods 10 are installed at the bottom of the top cover 3, and a filter screen 11 is connected to the bottom of the four groups of connecting rods 10. A lifting assembly 9 for adjusting the height of the top cover 3 is provided on the wastewater treatment tank 1. A cleaning mechanism for cleaning impurities on the filter screen 11 is provided on the left side wall of the wastewater treatment tank 1, and a collection box 5 for collecting impurities is installed on the right side wall of the wastewater treatment tank 1; before use, the electrical terminals of each electrical device are electrically connected to the electrical terminals of an external power source and a controller (installed on the front end face of the wastewater treatment tank 1) through wires. When treating wastewater, the wastewater is added into the inner cavity of the wastewater treatment tank 1 through the wastewater pipe 4. The filter screen 11 first filters impurities in the wastewater. The lifting assembly 9 can lift the top cover 3, and the top cover 3 drives the fixedly connected filter screen 11 to move upward through the four groups of connecting rods 10. When the filter screen 11 is flush with the top of the wastewater treatment tank 1, the cleaning mechanism quickly cleans the impurities on the filter screen 11, so that the impurities on the filter screen 11 are collected into the collection box 5, avoiding blockage of the filter screen 11 and affecting the filtration effect of the wastewater;

[0027] The inner wall of the wastewater treatment tank 1 is successively installed with an upper sealing plate 12 and a lower sealing plate 13 from top to bottom. Drain pipes are provided at the bottoms of the upper sealing plate 12 and the lower sealing plate 13. A drain pipe 17 is connected to the bottom of the wastewater treatment tank 1. Solenoid valves are provided on both the drain pipe 17 and the drain pipes. A chemical agent adding pipe 18 communicating with the inner cavity of the wastewater treatment tank 1 is installed on the left side wall of the wastewater treatment tank 1. A mixing component 14 is provided between the upper sealing plate 12 and the lower sealing plate 13. When the solenoid valve on the drain pipe of the upper sealing plate 12 is opened, the solenoid valve on the drain pipe of the lower sealing plate 13 is closed. At this time, the wastewater after filtering impurities remains between the upper sealing plate 12 and the lower sealing plate 13. Then, the chemical agent is added into the wastewater treatment tank 1 through the adding pipe 18. The mixing component 14 works to fully stir and mix the chemical agent and the wastewater, improving the absorption effect of the chemical agent and the wastewater, and improving the filtering and purification effect of the wastewater during ink production.

[0028] Two groups of ultraviolet germicidal lamps 16 are installed on the lower surface of the lower sealing plate 13. An activated carbon plate 15 is provided on the inner cavity bottom wall of the wastewater treatment tank 1. After the chemical agent and the wastewater are mixed for a period of time, the solenoid valve on the drain pipe at the bottom of the lower sealing plate 13 is opened to allow the wastewater to enter the bottom of the inner cavity of the wastewater treatment tank 1. The two groups of ultraviolet germicidal lamps 16 disinfect the wastewater. The activated carbon plate 15 can adsorb organic substances in the wastewater, remove pigments, dissolved organic substances, and odor substances, improving the purification effect of the wastewater. Finally, the solenoid valve on the drain pipe 17 is opened to discharge the filtered and purified wastewater.

[0029] Among them, the lifting component 9 includes a fixing frame 900 fixedly connected to the left side wall of the wastewater treatment tank 1. A stepping motor 901 is provided at the top of the fixing frame 900. The output end of the stepping motor 901 is connected to a lead screw 902. The bottom end of the lead screw 902 is rotationally connected to the inner bottom wall of the fixing frame 900 through a bearing. A limiting vertical rod 903 is installed on the inner wall of the fixing frame 900. The limiting vertical rod 903 is slidably connected to the top cover 3. The lead screw 902 is threadedly connected to the top cover 3.

[0030] Threaded holes and sliding holes adapted to the lead screw 902 and the limiting vertical rod 903 are provided on the top cover 3. The operation of the stepping motor 901 can drive the lead screw 902 to rotate forward or backward. After the top cover 3 threadedly connected to the lead screw 902 is slidably limited by the limiting vertical rod 903, the top cover 3 can move up and down. The top cover 3 drives the filter screen 11 to move up and down through four groups of fixedly connected connecting rods 10.

[0031] The cleaning mechanism includes a fixed box 6 fixedly connected to the top of the left outer wall of the wastewater treatment tank 1. A reduction motor 7 is provided on the front end face of the fixed box 6, and the output end of the reduction motor 7 is connected to a drive shaft 19. A rotating gear 20 is sleeved on the drive shaft 19; the fixed box 6 is fixedly installed on the top of the left side wall of the wastewater treatment tank 1, the drive shaft 19 is fixedly connected to the rotating gear 20, and the operation of the reduction motor 7 drives the rotating gear 20 fixedly connected to the drive shaft 19 to rotate forward or backward.

[0032] A moving tooth plate 8 is horizontally slidably connected in the fixed box 6 and penetrates through both ends of the fixed box 6. Multiple groups of meshing grooves are formed on the moving tooth plate 8, and each group of meshing grooves is meshed with the rotating gear 20. One end of the moving tooth plate 8 close to the collection box 5 is connected with a pushing plate 21; the pushing plate 21 is fixedly connected to the moving tooth plate 8. Since the multiple groups of meshing grooves formed on the moving tooth plate 8 are meshed with the rotating gear 20, after the two ends of the moving tooth plate 8 are limited by the fixed box 6, the moving tooth plate 8 drives the fixedly connected pushing plate 21 to move. The movement of the pushing plate 21 can push the impurities on the filter screen 11 into the collection box 5, realizing the cleaning of the impurities on the filter screen 11.

[0033] The mixing component 14 includes an ear plate 145. The ear plate 145 is fixedly connected to the right inner wall of the wastewater treatment tank 1, and a servo motor 144 is provided on the ear plate 145. The output end of the servo motor 144 is connected to a screw rod 140. The bottom end of the screw rod 140 is rotatably connected to the top of the lower sealing plate 13 through a bearing. A threaded sleeve 141 is threadedly connected to the screw rod 140. A guide groove 142 is formed on the right inner wall of the wastewater treatment tank 1. A connecting slider 143 is slidably connected in the guide groove 142, and the outer side wall of the connecting slider 143 is fixedly connected to the threaded sleeve 141;

[0034] The threaded sleeve 141 is fixedly connected to the connecting slider 143. The operation of the servo motor 144 drives the screw rod 140 to rotate. After the threaded sleeve 141 threadedly connected to the screw rod 140 is slidably limited by the connecting slider 143 through the guide groove 142, the threaded sleeve 141 can move up and down reciprocally.

[0035] A waterproof shell is provided on the outer side surface of the threaded sleeve 141. A drive motor 146 is installed in the inner cavity of the waterproof shell. The output end of the drive motor 146 is connected to a drive rod 147, and multiple groups of stirring blades 148 are provided on the outer wall of the drive rod 147; the threaded sleeve 141 is fixedly connected to the waterproof shell. The operation of the drive motor 146 drives the multiple groups of stirring blades 148 fixedly connected to the drive rod 147 to rotate. The reciprocally moving up and down threaded sleeve 141 drives the drive rod 147 and multiple groups of stirring blades 148 to move up and down, realizing the mixing and stirring of the chemical agent and the wastewater, improving the absorption effect of the chemical agent and the wastewater, and improving the wastewater purification effect.

[0036] Embodiment 2:

[0037] Reference Figure 1 , the difference between this embodiment and the first embodiment is that a transparent porthole is installed on the rear side of the wastewater treatment tank 1, support pads are installed at the bottoms of the two groups of support chassis 2, and damping pads are bonded to the lower surfaces of the support pads. The lower surfaces of the damping pads are embedded with staggered protrusions; the transparent porthole facilitates viewing the treatment effect of the wastewater in the wastewater treatment tank 1, and the support pads, damping pads, and staggered protrusions can increase the friction with the working ground, improving the stability of the entire wastewater treatment tank 1 during use.

[0038] Working principle: Before using the present invention, first, the electrical ends of each electrical device are electrically connected to the electrical ends of an external power supply and a controller (installed on the front end face of the wastewater treatment tank 1) through wires. When treating wastewater, the wastewater is added into the inner cavity of the wastewater treatment tank 1 through the wastewater pipe 4, and the impurities in the wastewater are filtered by the filter screen 11. The wastewater after filtering the impurities enters the next space through the drain pipe at the bottom of the upper sealing plate 12;

[0039] When it is necessary to clean the impurities on the filter screen 11, the operation of the stepping motor 901 on the lifting assembly 9 can drive the lead screw 902 to rotate forward or backward. After the top cover 3 threadedly connected to the lead screw 902 is slidably limited by the limiting vertical rod 903, the top cover 3 can move up and down. The top cover 3 drives the filter screen 11 to move up and down through four fixedly connected connecting rods 10. The filter screen 11 can be located in the inner cavity of the wastewater treatment tank 1 and can also make the filter screen 11 flush with the top of the wastewater treatment tank 1. After the filter screen 11 is flush with the top of the wastewater treatment tank 1, the operation of the deceleration electric motor 7 drives the rotating gear 20 fixedly connected to the drive shaft 19 to rotate forward or backward. Since the multiple meshing grooves formed on the moving tooth plate 8 are meshed with the rotating gear 20, and the two ends of the moving tooth plate 8 are limited by the fixed box 6, the moving tooth plate 8 drives the fixedly connected pushing plate 21 to move. The movement of the pushing plate 21 can push the impurities on the filter screen 11 into the collection box 5, realizing the cleaning of the impurities on the filter screen 11 and avoiding the blockage of the filter screen 11 from affecting the filtering effect of the wastewater;

[0040] The reagent is added into the inner cavity (between the upper sealing plate 12 and the lower sealing plate 13) of the wastewater treatment tank 1 through the reagent adding pipe 18. Then, the servo motor 144 on the mixing component 14 works, driving the screw 140 to rotate. After the threaded sleeve 141 threadedly connected to the screw 140 is slidably limited by the guide groove 142 and the connecting slider 143, the threaded sleeve 141 can move up and down reciprocally. The operation of the driving motor 146 drives the rotation of multiple stirring blades 148 fixedly connected to the driving rod 147. The reciprocally moving threaded sleeve 141 drives the driving rod 147 and multiple stirring blades 148 to move up and down, realizing the mixing and stirring of the reagent and the wastewater, improving the absorption effect of the reagent and the wastewater, and enhancing the wastewater purification effect. Finally, the solenoid valve on the drain pipe at the bottom of the lower sealing plate 13 is opened, enabling the wastewater to pass through the two groups of ultraviolet germicidal lamps 16 and the activated carbon plate 15. The two groups of ultraviolet germicidal lamps 16 and the activated carbon plate 15 disinfect the wastewater. The activated carbon plate 15 can adsorb organic substances in the wastewater, remove pigments, dissolved organic substances, and odor substances, realizing the filtration and purification treatment of the wastewater during ink production and improving the filtration and purification effect of the wastewater during ink production.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
