Description

Technical Field

[0001] The present invention relates to the technical field of water-based ink production, and specifically relates to a water-based ink sewage treatment device with a waste cleaning structure, and also relates to a treatment method for a water-based ink sewage treatment device with a waste cleaning structure. Background Art

[0002] As an environment-friendly printing material, water-based ink has been widely used in the printing industry due to its good printing effect and environmental protection characteristics. However, a certain amount of sewage is generated during the production and use of water-based ink. This sewage contains various components such as pigments, resins, and additives. If directly discharged without treatment, it will cause serious pollution to the environment. Traditional water-based ink sewage treatment equipment mostly uses methods such as physical precipitation, chemical flocculation, or biological degradation. Sediments are likely to accumulate inside the equipment and need to be cleaned regularly, which affects the continuous operation of the equipment.

[0003] The patent with the publication number CN221777620U discloses a sewage treatment device for water-based ink production. When filtering sewage, the motor is started to drive the screw to rotate between two support plates. The screw drives the nut block to move on the top of the treatment shell, thereby driving the driving plate to move on the inner top of the treatment shell, and then driving the cleaning brush to move on the top of the filter plate, so as to clean the impurities on the top of the filter plate, and part of the impurities are cleaned into the treatment shell, which can prevent too many impurities from accumulating and causing blockage of the filter plate, thus affecting the sewage filtration efficiency. When the sewage filtration is completed, the first opening and closing door is opened, the storage shell is pulled out, the sundries in the storage shell and the storage drawer are cleaned, then the filter drawer is pulled out, so as to replace the activated carbon layer in the filter drawer, and at the same time clean the filter drawer. Then, by opening the second opening and closing door, the filter cotton can be replaced.

[0004] Although the above solution continuously cleans the filter plate during the process of filtering and separating solids and liquids, enabling the water body to normally pass through the filter screen, however, it is necessary to pull out the storage shell and the filter drawer to clean the storage shell and the filter drawer. Since the storage shell and the filter drawer are not in the working position during the cleaning process, if sewage continues to pass through the filter screen at this time, the filtration effect of the sewage will be reduced. Therefore, the device needs to be paused and wait until the storage shell and the filter drawer are cleaned and installed back in place. Summary of the Invention

[0015] A treatment method of an aqueous ink sewage treatment device with a waste cleaning structure, which is applied to an aqueous ink sewage treatment device with a waste cleaning structure, includes the following steps:

[0016] S1. Put sewage and a flocculant into the precipitation cylinder, and the stirring mechanism stirs the sewage and the flocculant to mix the flocculant and the sewage evenly.

[0017] S2. After the flocculant combines with the impurities in the sewage, it gradually precipitates and accumulates at the bottom of the precipitation cylinder.

[0018] S3. After precipitation in the precipitation cylinder for a period of time, the discharging structure opens the feeding port on the housing, the precipitate falls into the loading port, and then the discharging structure closes the feeding port and discharges the treated sewage in the precipitation cylinder.

[0019] S4. The first driving structure drives the transfer disk to rotate, and transfers the loading port on the transfer disk without carrying the precipitate to directly below the feeding port.

[0020] S5. When the loading port carrying the precipitate rotates to the discharging port, the precipitate is discharged from the discharging port, and then the cleaning mechanism cleans the loading port.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. The present invention is provided with a mixing and precipitation mechanism, a circulating transfer mechanism and a cleaning mechanism. After the sewage in the precipitation cylinder is mixed with the flocculant, the precipitate can precipitate and be collected by the loading port of the transfer disk. As the first driving structure drives the rotation of the transfer disk, the precipitate is sequentially transferred to the discharging port for discharge. Then, new sewage and flocculant are continuously put into the precipitation cylinder for treatment. Through the coordinated work of the mixing and precipitation mechanism, the circulating transfer mechanism and the cleaning mechanism, the continuous collection and transfer of the precipitate are realized, avoiding the problem that the treatment process of the precipitation cylinder is interrupted due to the accumulation of the precipitate and the cleaning of the precipitate, and improving the treatment efficiency.

[0023] 2. The present invention designs the loading port into a contracted shape that is concave towards the middle of the transfer tray. When the loading port is docked with the feeding port, its cross-section shows a state of being larger at the top and smaller at the bottom, facilitating the smooth fall of sediment into the loading port and reducing the risk of blockage caused by improper shape. When the loading port rotates to the position docked with the discharging port, the cross-section changes to a state of being smaller at the top and larger at the bottom. This design not only enables the sediment to be quickly and smoothly discharged under the action of gravity but also significantly improves the discharging efficiency, avoids the discharging difficulty caused by sediment accumulation, and thus enhances the thoroughness and efficiency of cleaning the loading port.

[0024] 3. The present invention is provided with an auxiliary transfer structure and a positioning drive structure. When the loading port rotates to the position docked with the discharging port, the positioning drive structure drives the pushing component in the corresponding auxiliary transfer structure to move downward, pushing the sediment out of the loading port, thereby realizing the effective pushing and discharging of the sediment and effectively reducing the adhesion phenomenon of the sediment inside the loading port.

Detailed implementation manners

[0038] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0039] Refer to Figures 1 to 12Shown: An aqueous ink sewage treatment device with a waste cleaning structure, including a frame 1 and a mixing and precipitation mechanism 2, a circulation transfer mechanism 3, and a cleaning mechanism 4 that are fixedly arranged on the frame 1 in sequence from top to bottom; the mixing and precipitation mechanism 2 includes a horizontally arranged precipitation cylinder 21 and a stirring mechanism 22 arranged inside the precipitation cylinder 21, and a feeding port and a discharging port are respectively arranged at the top and bottom of the precipitation cylinder 21; the circulation transfer mechanism 3 includes a housing 31, an inlet and an outlet that are respectively docked with the discharging port are arranged at the top and bottom of the housing 31, a transfer disk 32 parallel to the axis of the precipitation cylinder 21 is arranged inside the housing 31, and the outer peripheral wall of the transfer disk 32 is attached to the inner cavity wall of the housing 31. A plurality of bearing ports 321 are arranged at equal intervals around the axis of the transfer disk 32, and an external part of the housing 31 is provided with a first driving structure 33 for driving the transfer disk 32 to rotate around its own axis; the cleaning mechanism 4 is used to clean the inside of the bearing port 321 that rotates to the outlet.

[0040] Specifically, the first driving structure 33 includes two connecting plates 331, a first rotating shaft 332, and a first rotating assembly 333. The two connecting plates 331 are arranged in parallel on both sides of the transfer disk 32. The two ends of the first rotating shaft 332 are respectively connected to the two connecting plates 331 through bearings, and the first rotating shaft 332 is coaxial and fixedly connected to the transfer disk 32. The first rotating assembly 333 is used to drive the first rotating shaft 332 to rotate.

[0041] First, sewage and a flocculant are put into the precipitation cylinder 21, and then the stirring mechanism 22 is started to uniformly mix the sewage and the flocculant by using the prior art. After the flocculant combines with the impurities in the sewage, it gradually precipitates to the bottom of the precipitation cylinder 21. When a certain amount of sediment accumulates in the precipitation cylinder 21, the sediment falls into the bearing port 321 of the transfer disk 32 under the action of gravity. Then the first driving structure 33 is started to drive the transfer disk 32 to rotate, so that the bearing port 321 without sediment moves below the inlet. If there is still sediment in the precipitation cylinder 21, it will continue to fall into the bearing port 321, and at the same time, the treated sewage in the precipitation cylinder 21 is discharged. After all the sediment is transferred to the bearing port 321, sewage and a flocculant are put into the precipitation cylinder 21 again to repeat the precipitation process. When the initially sediment-bearing bearing port 321 rotates to the outlet, the sediment is discharged under the action of gravity, and then the cleaning mechanism 4 cleans the bearing port 321. The sediment is sequentially collected and transferred through the multiple bearing ports 321 on the transfer disk 32, thus realizing the continuous collection and transfer of the sediment, avoiding the problem that the precipitation cylinder 21 is interrupted in the treatment process due to sediment accumulation and sediment cleaning, and improving the treatment efficiency.

[0042] Refer to Figure 3 Shown: The cross-section of the bearing port 321 is in a tapered contraction shape facing the middle of the transfer disk 32.

[0043] If the cross-section of the loading port 321 is straight or diverging and concave towards the middle of the transfer disk 32, when the loading port 321 rotates to the lowest position, its cross-section presents a structure that is larger at the top and smaller at the bottom, resulting in all the sediment in the loading port 321 accumulating towards the smaller outlet end. This accumulation state not only increases the extrusion between the sediments, making it difficult for the sediments to naturally discharge from the loading port 321, but also hinders the effective cleaning of the inside of the loading port 321 by the cleaning mechanism 4. Therefore, the loading port 321 is set to have a cross-section that is concave towards the middle of the transfer disk 32 in a contracted state. When the loading port 321 is docked with the feeding port, its cross-section presents a state that is larger at the top and smaller at the bottom, which facilitates the sediment to fall into the loading port 321 and reduces the possibility of blockage. When the loading port 321 rotates to the position docked with the discharging port, its cross-section changes to a state that is smaller at the top and larger at the bottom. This enlarged outlet is conducive to the rapid discharge of the sediment, significantly improving the discharge efficiency. In addition, the design of the loading port 321 in a contracted form also facilitates the effective cleaning of the side wall of the loading port 321 by the cleaning mechanism 4. After the sediment is discharged, the cleaning mechanism 4 can more easily reach various positions inside the loading port 321, thereby improving the thoroughness and efficiency of the cleaning of the loading port 321.

[0044] Refer to Figure 3 、 Figure 5 and Figure 6 As shown: The cyclic transfer mechanism 3 further includes a plurality of auxiliary transfer structures respectively arranged in a plurality of loading ports 321 and a positioning drive structure 37 for driving the auxiliary transfer structure located at the lowest position; the auxiliary transfer structure includes a pusher assembly 35 and a third drive structure 36 for driving the pusher assembly 35 to move along the diameter direction of the transfer disk 32 in the loading port 321.

[0045] Specifically, the positioning drive structure 37 includes two connecting brackets 371 and two linear drivers 372. The two connecting brackets 371 are respectively connected to the two connecting plates 331, and the two linear drivers 372 are respectively installed on the two connecting brackets 371. When the positioning drive structure 37 drives the pusher assembly 35 located at the lowermost end to work, the two linear drivers 372 are docked with the third drive structure 36.

[0046] Given that the sediment contains a high moisture content, which causes the sediment to adhere to each other and to the side wall of the bearing port 321, it is difficult to achieve effective discharge solely by the gravity of the sediment itself. Therefore, a plurality of auxiliary transfer structures and a positioning drive structure 37 are provided. Each auxiliary transfer structure corresponds to a bearing port 321, and the positioning drive structure 37 only applies a driving force to the auxiliary transfer structure in the bearing port 321 that is docked with the discharge port. When a certain bearing port 321 rotates to the position docked with the discharge port, the positioning drive structure 37 applies a driving force to the auxiliary transfer structure in this bearing port 321. At this time, the third drive structure 36 in the auxiliary transfer structure will push the pusher assembly 35 to move downward, thereby pushing out the sediment in the bearing port 321. Subsequently, the positioning drive structure 37 withdraws the driving force on the auxiliary transfer structure, and the pusher assembly 35 returns to the initial position. When the next bearing port 321 rotates to the discharge port, the positioning drive structure 37 will repeat the above process and apply a driving force to the auxiliary transfer structure in this bearing port 321. In this way, in addition to being affected by its own gravity, the sediment in the bearing port 321 will also be affected by an additional downward force, thus achieving effective pushing and discharging of the sediment and effectively reducing the adhesion phenomenon of the sediment inside the bearing port 321.

[0047] Refer to Figure 6 and Figure 7 As shown: The pusher assembly 35 includes a pusher plate 351 laid flat on the bottom of the bearing port 321. The third drive structure 36 includes a synchronous plate 361, two first drive assemblies 362, and a guiding and resetting assembly 363. The synchronous plate 361 is connected to the pusher plate 351. The two first drive assemblies 362 are respectively arranged at both ends of the synchronous plate 361. The guiding and resetting assembly 363 is used to guide the movement of the two first drive assemblies 362.

[0048] Specifically, the first drive assembly 362 includes a transmission plate 3621 and a plurality of drive plates 3622. The transmission plate 3621 is arranged parallel to the synchronous plate 361, and the transmission plate 3621 is connected to the guiding and resetting assembly 363. The plurality of drive plates 3622 are arranged parallel to each other, and both ends of the drive plate 3622 are respectively hinged to the transmission plate 3621 and the synchronous plate 361.

[0049] When the positioning drive structure 37 starts to work, two linear drivers 372 will exert a downward force on the two first drive components 362. This force will cause the two transmission plates 3621 to approach each other. However, since a parallelogram structure is formed between the transmission plates 3621 and the synchronization plate 361 through multiple drive plates 3622, and the synchronization plate 361 will not move in the same direction as the transmission plates 3621. During the movement of the transmission plates 3621, the synchronization plate 361 moves away from the transmission plates 3621 under the action of the drive plates 3622. Since the synchronization plate 361 is connected to the pusher plate 351, the movement of the synchronization plate 361 will drive the pusher plate 351 to move together. The pusher assembly 35 moves towards the outside of the loading port 321 under the push of the synchronization plate 361, thereby pushing out the sediment in the loading port 321.

[0050] Refer to Figure 6 and Figure 7 As shown: The guiding and resetting assembly 363 includes a third guide rod 3631 and a second spring 3632; the axis of the third guide rod 3631 is parallel to the movement direction of the synchronization plate 361. The third guide rod 3631 is connected to the transfer disk 32, and the two first drive components 362 are respectively slidably arranged at both ends of the third guide rod 3631; the second spring 3632 is sleeved on the middle part of the third guide rod 3631, and both ends of the second spring 3632 are respectively abutted against the two first drive components 362.

[0051] When the positioning drive structure 37 drives the two first drive components 362 to move, the two transmission plates 3621 will move along the third guide rod 3631 towards the middle part of the third guide rod 3631. During this process, the second spring 3632 is compressed and stores elastic potential energy. After the sediment in the loading port 321 is pushed out, the positioning drive structure 37 will remove the driving force applied to the two first drive components 362. At this time, the second spring 3632 releases the previously stored elastic potential energy, pushing the two transmission plates 3621 to move in opposite directions along the third guide rod 3631. Since the transmission plates 3621 are connected to their respective drive plates 3622, the movement of the transmission plates 3621 will drive the synchronization plate 361 to move through the drive plates 3622, and will ultimately be converted into the movement of the pusher plate 351, so that the pusher plate 351 is reset to the initial position, thus eliminating the need to add an additional drive source for each auxiliary transfer structure and reducing the maintenance complexity.

[0052] Refer to Figure 3 、 Figure 6 and Figure 8 As shown: The pusher plate 351 includes two mirror-image plate bodies 3511. The sides of the two plate bodies 3511 are respectively attached to the two side walls of the loading port 321. A plurality of expansion components 352 are equidistantly arranged in the middle of the two plate bodies 3511. The expansion components 352 are used to expand the area of the pusher plate 351.

[0053] Specifically, the expansion component 352 includes a first guide rod 3521, a second guide rod 3522, and two first springs 3523. The first guide rod 3521 is perpendicular to the synchronization plate 361 and connected to the synchronization plate 361. The second guide rod 3522 is perpendicularly intersecting with the first guide rod 3521, and the middle part of the second guide rod 3522 is connected to the first guide rod 3521. The two plate bodies 3511 are respectively slidably connected to both ends of the second guide rod 3522. The two first springs 3523 are respectively sleeved on both ends of the second guide rod 3522, and both ends of the first spring 3523 are respectively connected to the first guide rod 3521 and the plate body 3511.

[0054] Since the cross-section of the loading port 321 is in a contracted shape that is concave towards the middle of the transfer disk 32, if the size of the pusher plate 351 is fixed, during the process of the pusher plate 351 moving from the bottom of the loading port 321 towards the opening end of the loading port 321, both sides of the pusher plate 351 will be separated from the side wall of the loading port 321, resulting in the pusher plate 351 being unable to apply a driving force to the sediment on the side wall of the loading port 321. Therefore, the expansion component 352 is provided. During the working process, when the pusher plate 351 is in the initial position, the two plate bodies 3511 are in contact with each other and compress the multiple first springs 3523 therebetween, so that all the multiple first springs 3523 are in the energy storage state. At this time, the elastic force of the first spring 3523 urges one side of the plate body 3511 to closely fit the side wall of the loading port 321. As the third driving structure 36 is activated and pushes the pusher plate 351 to move outside the loading port 321, the multiple first springs 3523 synchronously release the stored elastic potential energy, pushing the two plate bodies 3511 to separate from each other along the direction of the second guide rod 3522, thereby ensuring that the edges of the plate bodies 3511 can continuously contact and fit the continuously changing side wall contour of the loading port 321, effectively avoiding the retention of sediment on the side wall of the loading port 321 and improving the cleaning efficiency.

[0055] Refer to Figure 3 、 Figure 9 and Figure 10 As shown in

[0056] Specifically, the feeding component 341 includes a second rotating shaft 3411 and a feeding plate 3412. Both ends of the second rotating shaft 3411 extend to the outside of the housing 31. The feeding plate 3412 is connected to the second rotating shaft 3411. The second driving structure 342 includes a third rotating shaft 3421. The third rotating shaft 3421 is parallel to the second rotating shaft 3411. Fourth rotating shafts 3422 perpendicular to the third rotating shaft 3421 are provided at both ends of the third rotating shaft 3421. A bevel gear transmission assembly 3423 is provided between the third rotating shaft 3421 and the fourth rotating shaft 3422 for transmission connection. Two worm and gear transmission assemblies 3424 are provided on the fourth rotating shaft 3422. The worm and the gear in the worm and gear transmission assembly 3424 are respectively connected to the second rotating shaft 3411 and the fourth rotating shaft 3422.

[0057] In the stage of mixing the mixed sewage and the flocculant, due to the strong fluidity of the sewage, the sewage may flow into the gap between the housing 31 and the transfer disk 32. Therefore, the feeding structure 34 is provided. Before the sewage and the flocculant are put into the sedimentation cylinder 21, the two feeding plates 3412 in the two feeding components 341 abut against each other to close the feeding port of the housing 31. After the sewage and the flocculant are mixed, the sediment accumulates at the upper ends of the two feeding plates 3412, and the sewage is above the sediment layer. After the sewage is discharged, the second driving structure 342 works. The third rotating shaft 3421 rotates, driving the two fourth rotating shafts 3422 to rotate through the two bevel gear transmission assemblies 3423. The fourth rotating shaft 3422 drives the two second rotating shafts 3411 in the two feeding components 341 to rotate simultaneously through the two worm and gear transmission assemblies 3424 on it, so that the two feeding plates 3412 open towards both sides. The sediment on the feeding plate 3412 slides along the feeding plate 3412 into the bearing port 321. By controlling the opening and closing of the feeding port, sewage flowing into the gap between the housing 31 and the transfer disk 32 can be avoided.

[0058] Refer to Figure 3 and Figure 11 As shown: The cleaning mechanism 4 includes a cleaning component 41 and a fourth driving structure 42; the cleaning component 41 includes a cleaning roller 411 and a second rotating component 412 for driving the cleaning roller 411 to rotate; the fourth driving structure 42 is used to drive the cleaning component 41 to move along the bearing port 321.

[0059] After the sediment in the loading port 321 is discharged under the action of the auxiliary transfer structure, there may still be some sediment sticking to the pusher plate 351. Therefore, a cleaning component 41 and a fourth driving structure 42 are provided. After the auxiliary transfer structure discharges most of the sediment in the loading port 321, the cleaning mechanism 4 is immediately started. The second rotating component 412 first drives the cleaning roller 411 to start rotating, and then the fourth driving structure 42 is started to drive the cleaning component 41 to move along the loading port 321. The rotating cleaning roller 411 contacts the pusher plate 351 with its surface, and uses friction to peel off the remaining sediment, thus realizing the comprehensive cleaning of the remaining sediment in the loading port 321 and improving the cleanliness of the loading port 321.

[0060] Refer to Figure 3 、 Figure 11 and Figure 12 As shown in: The fourth driving structure 42 includes a guiding component 421 and a second driving component 422 provided at both ends of the cleaning component 41; the guiding component 421 is used to guide the movement of the cleaning component 41; the second driving component 422 is used to drive the cleaning component 41 to move along the guiding component 421.

[0061] Specifically, the guiding component 421 includes a fourth guide rod 4211 and a first connecting block 4212. The axis of the fourth guide rod 4211 is parallel to the axis of the transfer disk 32. The first connecting block 4212 is slidably arranged on the fourth guide rod 4211, and the first connecting block 4212 is connected to one end of the cleaning roller 411 through a bearing. The second driving component 422 includes a screw rod 4221 and a second connecting block 4222. The screw rod 4221 is arranged parallel to the fourth guide rod 4211. The second connecting block 4222 is threadedly connected to the screw rod 4221. The other end of the cleaning roller 411 is connected to the second connecting block 4222 through a bearing.

[0062] If the fourth driving structure 42 is arranged directly below the discharge port, during the cleaning process of the cleaning component 41, the sediment will fall onto the fourth driving structure 42, which will affect the operation of the fourth driving structure 42. Therefore, the guiding component 421 and the second driving component 422 are respectively arranged at both ends of the cleaning component 41. The guiding component 421 and the second driving component 422 can keep the cleaning component 41 in a stable state. When the fourth driving structure 42 is started, the screw rod 4221 rotates, and the second connecting block 4222 moves along the screw rod 4221. At the same time, the second connecting block 4222 drives the first connecting block 4212 to move along the fourth guide rod 4211 through the cleaning roller 411, so that the cleaning roller 411 can move along the loading port 321 to realize the effective cleaning of the entire loading port 321. By arranging the guiding component 421 and the second driving component 422 at both ends of the cleaning roller 411, the sediment is prevented from falling onto the fourth driving structure 42.

[0063] A treatment method for an aqueous ink sewage treatment device with a waste cleaning structure, which is applied to an aqueous ink sewage treatment device with a waste cleaning structure, includes the following steps:

[0064] S1. Put sewage and a flocculant into the precipitation cylinder 21, and the stirring mechanism 22 stirs the sewage and the flocculant to make the flocculant and the sewage mix evenly;

[0065] S2. After the flocculant combines with the impurities in the sewage, it gradually precipitates and accumulates at the bottom of the precipitation cylinder 21;

[0066] S3. After precipitation in the precipitation cylinder 21 for a period of time, the feeding structure 34 opens the feeding port on the housing 31, the precipitate falls into the bearing port 321, and then the feeding structure 34 closes the feeding port and discharges the treated sewage in the precipitation cylinder 21;

[0067] S4. The first driving structure 33 drives the transfer disk 32 to rotate, and transfers the bearing port 321 on the transfer disk 32 without bearing precipitate to directly below the feeding port;

[0068] S5. When the bearing port 321 bearing the precipitate rotates to the discharge port, the precipitate is discharged from the discharge port, and then the cleaning mechanism 4 cleans the bearing port 321.

The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
