Description

Technical Field

[0001] The present invention relates to the technical field of pigment wastewater treatment, and more specifically, to a wastewater treatment device for cleaning oil painting pigments. Background Art

[0002] The pigment waste liquid filtering device is a key equipment for treating pigment waste liquid in industrial production. Its core function is to remove suspended solids, pigment particles, heavy metal ions and organic pollutants in the waste liquid through physical, chemical or biological means, so as to achieve the up-to-standard discharge or resource utilization of the waste liquid.

[0003] After retrieval, a Chinese patent with the publication number CN113480049B discloses a device and its treatment process for treating painting pigment wastewater, including a pigment barrel, a filtering device and a flocculant package. A fixing component is arranged on the pigment barrel, and the filtering device is installed on the fixing component; after the flocculant package is mixed with the pigment wastewater in the pigment barrel, it is then filtered through the filtering device. The structure of the present invention is scientific and reasonable, and it is safe and convenient to use. Compared with the previous method of pouring the wastewater outdoors or into the sewer after cleaning the painting pigment pen, the above solution neither needs to pour the dirty wastewater outdoors nor into the sewer. Only by flocculating and filtering the wastewater can clear water be obtained. However, when the above solution is actually used, there are still the following deficiencies:

[0004] When the above-mentioned pigment wastewater treatment device is used, the filtering device is responsible for filtering the wastewater. During the filtering process, sediment will gradually adhere to the surface of the filtering device, resulting in a decrease in the filtering efficiency. Manual cleaning of the sediment is required, which increases the complexity during the use of the device. In addition, the addition of the medicament also needs to be manually completed, and the automatic addition of the medicament cannot be achieved, which brings inconvenience to the actual use of the device.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By setting up the chemical adding unit, the staff only needs to inject the wastewater into the separation sieve cylinder and start the motor, and the device can automatically complete the chemical adding and mixing process. The first motor drives the stirring head to rotate to ensure the full mixing of the wastewater and the chemical. The second motor drives a plurality of medicine supply assemblies to operate in sequence through the eccentric wheel mechanism, and realizes the accurate quantitative dosing of the chemical by the coordinated action of the one-way valve and the sliding plug, avoiding the errors and intermittency of manual operation. Every time the eccentric wheel rotates one week, the medicine supply assembly completes the medicine suction and injection actions in a cycle, not only ensuring the continuity and uniformity of the chemical adding, but also reducing the manual intervention and lowering the operation complexity. In addition, this design realizes the synchronization of chemical adding and stirring through mechanical linkage, optimizing the treatment process;

[0028] 2. The automatic floc cleaning solution realizes the removal of flocs attached to the inner wall of the separation sieve cylinder through the linkage design of the winding wheel and the pulling wire. In the initial stage, the winding wheel first gathers the scattered pulling wire. After the pulling wire is tightened, it drives the cleaning ring to move upward along the inner wall of the separation sieve cylinder. Using its frustum-shaped structure, the flocs are gradually scraped to the top and pushed into the annular collection box. The whole process requires no manual intervention. The gap design between the cleaning ring and the separation sieve cylinder not only ensures the effective scraping of flocs but also avoids frictional damage. This automatic cleaning mechanism not only significantly reduces the manual cleaning frequency and operation intensity but also improves the continuity of floc collection and the stability of the device operation, making the pigment wastewater treatment process more efficient, labor-saving, and easy to maintain;

[0029] 3. The optimization of the floc treatment process is realized through the delayed winding mechanism of the pulling wire. In the initial stage, the winding wheel preferentially gathers the scattered pulling wire, providing sufficient centrifugal dehydration time for the flocs in the separation sieve cylinder. After the dehydration is completed, the straightened pulling wire drives the cleaning ring to perform scraping operations. This timing control design enables the flocs to be effectively dehydrated first and then cleaned, ensuring both the dehydration effect and avoiding the problem of excessive moisture content caused by premature cleaning. The delayed action of the pulling wire device realizes the natural connection of the two processes of centrifugal dehydration and mechanical cleaning, eliminating the need for an additional timing device, which not only simplifies the structure but also ensures the treatment quality. At the same time, the entire dehydration and cleaning process is fully automated;

[0030] 4. The linkage control of three key processes can be synchronously completed through a single operation of the crossbar moving downward, realizing an efficient wastewater treatment process. First, the device moves downward and fixes the stirring component. Using the flexible meshing characteristics of the rubber convex packages, the power transmission is ensured, and the separation sieve cylinder rotates stably. At the same time, the oblique pressure of the ejector rod triggers the release of the locking mechanism, enabling the sliding seat to be automatically separated under the action of gravity, and cooperating with the buffer device to complete the solid-liquid separation of the flocs. Finally, through the precise docking of the driving structure, the motor power is transmitted. The entire operation process only requires a single downward action to trigger multiple mechanical linkages, which not only simplifies the operation steps and reduces the intensity of manual intervention but also ensures the close connection of each process through timing control. The structure of this device is simple and compact, using mechanical transmission to control the operation of each component, without using complex electronic control circuits, making the operation of the device more stable, with the advantages of extending the service life and reducing the maintenance cost.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] The present invention provides a wastewater treatment device for cleaning oil painting pigments. Refer to Figures 1 - 14 As shown, it includes a base 101.

One end of the top plate 105 away from the sliding sleeve 103 is fixed with a jacking rod 78;

[0049] Refer to Figure 13 and Figure 14As shown in the figure, a chemical agent adding unit is provided on the base 101. The chemical agent adding unit is composed of a chemical agent adding component, a liquid supply base 93, a rotating component and a plurality of chemical agent supply components. The liquid supply base 93 is fixed on the top surface of the base 101. The chemical agent adding component includes a plurality of chemical agent adding pipes 91 and a plurality of brackets 92. Each bracket 92 is fixed on the outer peripheral surface of the fixed base 41. The plurality of chemical agent adding pipes 91 are respectively rotatably installed on the plurality of brackets 92. The rotating component includes a second motor 94, a shaft rod 95 and an eccentric wheel 98. The second motor 94 is installed on the inner top surface of the liquid supply base 93. The shaft rod 95 is rotatably installed inside the liquid supply base 93, and the shaft rod 95 and the liquid supply base 93 are coaxially arranged. The eccentric wheel 98 is fixedly sleeved on the shaft rod 95, and the eccentric wheel 98 and the shaft rod 95 are eccentrically arranged. A first gear 96 is fixedly sleeved on the output shaft of the second motor 94. A second gear 97 is fixedly sleeved on the shaft rod 95. The first gear 96 and the second gear 97 are meshed with each other.

[0050] See Figure 13 As shown in the figure, a plurality of chemical agent supply components are all arranged inside the liquid supply base 93, and the plurality of chemical agent supply components are circumferentially and arrayedly distributed. The chemical agent supply component includes a sealed cylinder body 99, a sliding plug 910, a rod body 911, two installation pipes 913, two one-way valves 914 and a chemical agent bin 915. The sealed cylinder body 99 is fixed inside the liquid supply base 93. The sliding plug 910 is hermetically and slidably connected inside the sealed cylinder body 99, and the sliding plug 910 and the sealed cylinder body 99 are connected by a third spring 912. One end of the rod body 911 is fixed on the sliding plug 910, and the other end extends to the outside of the sealed cylinder body 99. The two installation pipes 913 are both communicated with the sealed cylinder body 99. The two one-way valves 914 are respectively installed on the two installation pipes 913. The chemical agent bin 915 is arranged on the base 101. One end of one installation pipe 913 away from the sealed cylinder body 99 is communicated with the chemical agent bin 915, and the other end of the other installation pipe 913 away from the sealed cylinder body 99 is communicated with the corresponding chemical agent adding pipe 91.

[0051] When the pigment wastewater needs to be purified, the staff first put the pigment wastewater into the inside of the separation sieve cylinder 46. Refer to Figure 2 , since the sliding seat 42 is in the position sleeved on the outer sleeve, the pigment wastewater will accumulate in the sliding seat 42 and submerge the separation sieve cylinder 46. Then, the staff use the chemical agent adding unit to automatically add the chemical agent. Specifically, the staff start the first motor 31 and the second motor 94 at the same time. When the first motor 31 operates, it can drive the rotating shaft 32 to rotate through the transmission part 34, so that the rotating shaft 32 drives the stirring head 33 to rotate, so as to facilitate the stirring head 33 to stir and mix the waste liquid and the chemical agent. When the second motor 94 operates, it can drive the shaft rod 95 to rotate through the meshed first gear 96 and second gear 97, and the eccentric wheel 98 connected to the shaft rod 95 rotates accordingly. Refer to Figure 13 and Figure 14As shown, during the rotation of the eccentric wheel 98, the eccentric wheel 98 will successively squeeze a number of rod bodies 911, causing a number of medicine supply components to operate in sequence, realizing the automatic addition of medicine. For the medicine supply components, the current-limiting directions of the two one-way valves 914 are opposite. One of the one-way valves 914 restricts the medicine to only enter the sealed cylinder 99, while the other one-way valve 914 restricts the medicine to only flow out of the sealed cylinder 99. When the rod body 911 is squeezed by the eccentric wheel 98, the rod body 911 can drive the sliding plug 910 to move. The movement of the sliding plug 910 can push the medicine in the sealed rod body 911 into the corresponding dosing tube 91 through the corresponding mounting tube 913, so that the medicine flows into the pigment wastewater through the dosing tube 91. When the eccentric wheel 98 separates from the rod body 911, the rod body 911 and the sliding plug 910 will automatically reset under the action of the third spring 912. During this process, the sliding plug 910 extracts the medicine in the medicine storage bin 915 through the corresponding mounting tube 913, realizing the automatic replenishment of the medicine. Based on the above process, during the process of the eccentric wheel 98 rotating 360° around the shaft rod 95, a number of medicine supply components automatically add medicine to the pigment wastewater in sequence. This design realizes the automatic addition of medicine, not only eliminating the need for staff to manually add medicine, but also being able to accurately control the addition amount of the medicine. It should be noted that when the eccentric wheel 98 rotates 360° around the shaft rod 95, the second motor 94 automatically stops running, and the automatic medicine addition action ends. In addition, the medicine stored in the medicine storage bin 915 includes inorganic coagulants such as polyaluminum chloride, aluminum sulfate, ferric chloride, etc., which are used to neutralize the charge on the surface of the pigment particles and promote flocculation sedimentation. It also includes flocculants such as anionic or non-ionic polyacrylamide, which help fine particles aggregate into large flocs for easy precipitation or filtration. It also includes a pH regulator for adjusting the pH of the wastewater to an appropriate range (usually 6-9) to optimize the coagulation and sedimentation effects. It also includes a demulsifier. For pigment wastewater containing emulsified oil, a demulsifier (such as a cationic surfactant) can be used to break the emulsion for easy oil-water separation;

When the annular collection box 51 is placed on the two support plates 52, the two bumps 54 are respectively stuck into the two grooves 53, and the top of the annular collection box 51 is flush with the top of the separation sieve cylinder 46;

[0059] For the annular collection box 51, it is detachably arranged on the separation sieve cylinder 46 to facilitate the staff to uniformly process the dirt collected in the annular collection box 51. Specifically, when placing the annular collection box 51, the staff can respectively align the two bumps 54 with the two grooves 53, and then put the annular collection box 51 on the top of the separation sieve cylinder 46 so that the annular collection box 51 is placed on the two support plates 52. At this time, the two bumps 54 are respectively stuck into the two grooves 53. This design facilitates the staff to quickly disassemble and assemble the annular collection box 51;

The convex bumps 1 62 and the convex bumps 2 64 are all made of rubber material;

[0061] See also Figure 5 and Figure 6 As shown, a traction unit is arranged on the column 102, and the traction unit includes a driving assembly and a winding assembly. The driving assembly includes a side plate 81, a rotating rod 82, a transmission rod 83, a driving slot 85 and a driving block 86. The side plate 81 is fixed on the column 102, and the rotating rod 82 is rotatably mounted on the top surface of the side plate 81 through a bearing seat. The transmission rod 83 is rotatably mounted on the side of the column 102 through a bearing seat, and the rotating rod 82 and the transmission rod 83 are perpendicular to each other. The rotating rod 82 and the transmission rod 83 are connected by two mutually meshing bevel gears 85. 4 transmission connection, the driving groove 85 is provided at the top end of the driving rod 83, the driving block 86 is fixed on the output shaft of the motor 31, the driving groove 85 is arranged opposite to the driving block 86, and the cross-sections of the driving groove 85 and the driving block 86 are both rectangular structures; the winding assembly includes a winding wheel 87, a pull wire 88 and a wire support drum 89, the winding wheel 87 is fixed to one end of the rotating rod 82, one end of the pull wire 88 is connected to the winding wheel 87, and the other end is connected to the cleaning ring 48, and the wire support drum 89 is fixed on the side plate 81 for supporting the pull wire 88;

[0062] Various reagents are mixed with the pigment wastewater under the rotation of the stirring head 33, so that the colloidal particles in the pigment wastewater are destabilized and aggregated to form larger flocs. After the subsequent separation treatment, the flocs can be purified for the pigment wastewater. After the reagents and the pigment wastewater fully react, the color of the pigment wastewater will change significantly, and the flocs will also condense and form obviously. At this time, the staff turns off the motor 31 and pulls the crossbar 21 downward. When the crossbar 21 moves downward, three actions are triggered synchronously:

[0063] First, when the cross bar 21 moves downward, it drives the sliding sleeve 103 and the top plate 105 to move downward, so that the stirring assembly moves downward accordingly. In this process, the staff can clamp the slot 23 on the clamping column 24 by rotating the rotating plate 22. Under the cooperation of the clamping effect of the slot 23 and the elastic force of the spring 104, the positions of the sliding sleeve 103, the top plate 105 and the stirring head 33 are fixed. When the stirring head 33 moves downward, the transmission plate 2 63 thereon moves downward accordingly, which makes the plurality of convex bumps 1 62 and the plurality of convex bumps 2 64 in a state of mutual meshing or mutual compression. Figure 12As shown, when the plurality of convex bulges 1 62 and the plurality of convex bulges 2 64 form a meshing state, the rotational movement of the transmission plate 2 63 can be transmitted to the transmission plate 1 61 through the plurality of convex bulges 1 62 and the plurality of convex bulges 2 64, so that the transmission plate 1 61 rotates following the transmission plate 2 63. When the plurality of convex bulges 1 62 and the plurality of convex bulges 2 64 are pressed against each other, the plurality of convex bulges 2 64 will also be staggered with the plurality of convex bulges 1 62 during the rotation process, and finally form a meshing state. In summary, when the stirring head 33 moves downward following the sliding sleeve 103, the transmission plate 1 61 and the transmission plate 2 A transmission relationship can be formed between the two transmission plates 63, so that power is transmitted to the transmission plate 2 63. When the transmission plate 2 63 rotates, the separation screen drum 46 can be driven to rotate through the bottom plate 47, so as to facilitate the subsequent separation and treatment of flocs in the wastewater. It is worth noting that the convex bulge 1 62 and the convex bulge 2 64 are both made of rubber material. When the convex bulge 1 62 and the convex bulge 2 64 are squeezed against each other, the convex bulge 1 62 and the convex bulge 2 64 can be deformed, thereby avoiding the convex bulge 1 62 and the convex bulge 2 64 from being squeezed and damaged, thereby ensuring the stable transmission action.

[0064] Second, when the cross bar 21 drives the sliding sleeve 103 and the top plate 105 to move downward, the top rod 78 on the top plate 105 moves downward accordingly. The top rod 78 can squeeze the inclined surface of the fixed plate 77 during the downward movement. Figure 4 As shown, when the inclined surface of the fixing plate 77 is squeezed, the fixing plate 77 can drive the sliding plate 73 to move, so that the locking block 74 moves in the direction away from the sliding seat 42. When the locking block 74 is disengaged from the locking groove 75, the locking block 74 no longer provides a locking effect on the sliding seat 42. At this time, the sliding seat 42 will move downward under the action of gravity and separate from the outer cylinder 44. When the sliding seat 42 is separated from the outer cylinder 44, the liquid will flow into the sliding seat 42, and the flocs will be intercepted by the separation screen cylinder 46 to achieve the effect of solid-liquid separation. In addition, when the sliding seat 42 falls, the buffer bag 43 plays a buffering role on it, preventing the sliding seat 42 from directly impacting the fixing seat 41, and providing a certain protection for the sliding seat 42.

[0065] Third, when the top plate 105 moves downward following the sliding sleeve 103, the motor 31 moves downward accordingly, and the driving block 86 fixed on the output shaft of the motor 31 also moves downward. In this process, if the driving block 86 is just opposite to the driving slot 85, the driving block 86 can be smoothly inserted into the driving slot 85. If the driving block 86 and the driving slot 85 are in a mutually misaligned state, the staff can fine-tune the angle of the driving slot 85 by rotating the transmission rod 83 until the driving block 86 is smoothly inserted into the driving slot 85. When the driving block 86 is plugged into place, the card slot 23 on the rotating plate 22 can be stuck on the card column 24. Furthermore, since the cross-sections of the driving block 86 and the driving slot 85 are both rectangular structures, when the motor 31 is running, the driving block 86 can directly drive the transmission rod 83 to rotate;

[0066] In summary, when the staff lowers the sliding sleeve 103, the stirring assembly moves downward and is fixed. Power is transmitted through the engagement of the convex hulls. The ejector rod 78 presses down on the inclined plane, releasing the lock of the sliding seat 42, causing it to fall to achieve solid-liquid separation. The first motor 31 moves downward, and the driving block 86 is inserted into the driving groove 85 of the transmission rod 83, transmitting torque through the rectangular cross-section. After completing the above operations, the staff starts the first motor 31. Since a transmission relationship has been established between the first transmission plate 61 and the second transmission plate 63, the stirring head 33 can drive the bottom plate 47 to rotate through the transmission assembly. When the bottom plate 47 rotates, the separation sieve cylinder 46 rotates accordingly. In addition, since the sliding seat 42 has been separated from the outer cylinder 44, only the flocs generated by condensation and some residual water exist in the separation sieve cylinder 46. When the separation sieve cylinder 46 rotates at a high speed, under the action of centrifugal force, the flocs will adhere to the inner wall of the separation sieve cylinder 46, and the water doped in the flocs will be thrown out through the sieve holes on the separation sieve cylinder 46 and onto the inner wall of the outer cylinder 44. This can remove the residual water in the flocs, facilitating better subsequent treatment of the flocs and improving the solid-liquid separation effect. At the same time, the rotation action of the first motor 31 can also be transmitted to the transmission rod 83 through the driving block 86 and the driving groove 85. When the transmission rod 83 rotates, it can drive the rotating rod 82 to rotate through two meshing bevel gears 84, causing the rotating rod 82 to drive the winding wheel 87 to rotate slowly. Refer to Figure 6 As shown, in the initial state, the drawstring 88 is scattered on the wire support tray 89. Therefore, in the early stage of the rotation of the winding wheel 87, the winding wheel 87 will slowly wind up the drawstring 88. At this time, the drawstring 88 will not exert a pulling force on the cleaning ring 48, and the cleaning ring 48 will not move. When the scattered drawstring 88 is completely wound up, the winding action of the winding wheel 87 will cause the drawstring 88 to exert a pulling force on the cleaning ring 48, thereby causing the cleaning ring 48 to move upward. Refer to Figure 9 and Figure 10 As shown, the cleaning ring 48 has a frustum-shaped structure with a hollow middle. The outer edge of the bottom end of the cleaning ring 48 does not contact the inner surface of the filter sieve cylinder, but the gap between them is very small. The top opening of the cleaning ring 48 fits closely with the outer circumference of the bottom plate 47. Therefore, during the upward movement of the cleaning ring 48, it can scrape the flocs attached to the inner wall of the separation sieve cylinder 46 upward until the flocs move to the top of the separation sieve cylinder 46. When the cleaning ring 48 moves out of the separation sieve cylinder 46, the flocs will be pushed out of the separation sieve cylinder 46 by the cleaning ring 48 and fall into the annular collection box 51, realizing the automatic collection of the flocs. This design eliminates the need for manual frequent cleaning of the separation sieve cylinder 46 and can automatically collect the flocs generated during the purification of pigment wastewater;

[0067] It should be noted that since both guide rods 410 are fixed to the outer cylinder 44 and the two guide frames 49 are respectively slidably sleeved on the two guide rods 410, the cleaning ring 48 will not rotate with the separation sieve cylinder 46 but remains stationary. In this stationary state, the separation sieve cylinder 46 can be smoothly pulled up by the pull wire 88. Additionally, by arranging the scattered pull wire 88, a time delay effect is provided for the movement of the cleaning ring 48. Because during the process of the winding wheel 87 winding up the scattered pull wire 88, the pull wire 88 does not exert a pulling force on the cleaning ring 48, and at this time the cleaning ring 48 does not move. This stage provides time for the centrifugal water separation of the flocs. When the pull wire 88 is wound up and straightened, the centrifugal water separation of the flocs is also completed, and at this time the cleaning ring 48 will push and clean the flocs.
