Description

Technical Field

[0001] The utility model relates to the technical field of ink waste liquid recovery, in particular to a treatment device for ink waste liquid recovery. Background Art

[0002] Waste ink liquid refers to waste liquid generated during industrial production processes such as printing, coating, and spraying. These waste liquids usually contain ink components and other possible additives, such as solvents, pigments, and adhesives. Some waste liquids may also contain paper scraps, residues, or particles adsorbed in the environment. However, some components in waste ink liquid still have reuse value. For example, some organic solvents can be treated and recycled to reduce production costs. Therefore, they need to be recycled to maximize the use of resources and reduce waste.

[0003] The patent with the announcement number CN212236825U discloses a green and environmentally friendly printing ink waste liquid recovery and treatment device, including a stirring barrel, an oil inlet is opened on one side of the top of the stirring barrel, a filter layer is fixedly installed in the oil inlet, a main shaft is fixedly connected to the internal axis of the stirring barrel, a spiral fan is fixedly connected to the main shaft layer, a motor is fixedly installed at one end of the main shaft near the oil inlet, a support frame is fixedly arranged at the bottom of the motor, and the support frame is fixedly connected to the base, support bearings are arranged at both ends of the main shaft, a rubber sealing ring is installed on one side of the support bearing near the inner wall of the stirring barrel, and a cover body is threadedly connected to the outer side of the main shaft away from the oil inlet.

When some solid impurities adhere to the surface, it is difficult to clean these impurities. Over time, it is likely to cause the filter net and the molecular treatment net to be blocked, thereby affecting the filtering effect, which is relatively inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1-Figure 6A processing device for recycling waste ink liquid comprises a bracket 1, a collecting box 2 installed on one side of the bracket 1, a feeding pipeline 3 installed above the bracket 1 and a feeding pipe 4 installed at the other end of the feeding pipeline 3, a U-shaped connecting block 5 is fixedly connected to the side of the feeding pipeline 3 away from the feeding pipeline, a connecting pipe 6 is fixedly connected to the other end of the U-shaped connecting block 5, and the other end of the connecting pipe 6 is fixedly connected to and communicated with the collecting box 2, a rotating mechanism is connected to one side of the upper end of the U-shaped connecting block 5, a replacement column 9 is connected to the inner wall of the U-shaped connecting block 5, the center of the upper surface of the replacement column 9 is connected to the rotating mechanism, a plurality of equidistantly distributed filter cavities 901 are penetrated on the upper surface of the replacement column 9, the inner walls of the plurality of filter cavities 901 are connected to filter components, and the filter cavities 901 are aligned with and communicated with the connecting pipe 6 and the feeding pipe 4.

[0025] The processing device for recycling waste ink in the utility model is similar in structure to the existing waste ink recycling processing device, such as a green and environmentally friendly printing waste ink recycling processing device disclosed in the patent with publication number CN212236825U. Figures 1 to 6 As shown, when the processing device for recycling waste ink in the utility model is in use, the external waste ink is first poured into the feed hopper on the feed pipe 3, and then the waste ink is discharged into the replacement column 9 in the middle of the U-shaped connecting block 5 below through the discharge pipe 4, and after entering the replacement column 9, it enters the filter assembly in the filter cavity 901, and the internal impurities are filtered out by the filter assembly, and the remaining ink liquid flows out of the filter assembly.

[0026] After the filter assembly has been used for a period of time, some impurities will accumulate inside the filter assembly. These impurities are likely to affect the subsequent filtering effect. At this time, there is no need to stop the machine. Just turn on the rotating mechanism through an external controller. After the rotating mechanism is started, it drives the replacement column 9 to rotate. After the replacement column 9 rotates, the filter assembly originally located between the U-shaped connecting blocks 5 will be rotated to the outside of the U-shaped connecting block 5. At the same time, one of the filter assemblies originally located outside the U-shaped connecting block 5 will be driven by the replacement column 9 to rotate between the U-shaped connecting blocks 5 and align with the upper discharge pipe 4 and the lower connecting pipe 6. After that, the ink liquid with impurities flowing out of the discharge pipe 4 will continue to be filtered by the new filter assembly.

[0027] After that, it is only necessary to clean up the impurities inside the filter component that is rotated to the outside of the U-shaped connecting block 5. Through the above steps, not only can the filter component be replaced at any time, but the replacement is also very convenient and easy to operate. Finally, it should be specially noted that: the external controller is a common technology at present, so it is not described in detail; a sealing ring is provided at the connection between the replacement column 9 and the U-shaped connecting block 5, which can prevent the ink liquid from flowing out to the outside.

[0028] Please refer to Figure 6The filter assembly includes a filter tube 13 and a filter screen 14 . The outer wall of the filter tube 13 is slidably connected to the inner wall of the filter cavity 901 , and the inner wall of the lower end of the filter tube 13 is fixedly connected to the outer wall of the filter screen 14 .

[0029] More specifically, when it is necessary to filter the impurities in the ink waste liquid, it is only necessary to insert the filter tube 13 into the filter cavity 901, and then the ink waste liquid flowing out from the upper discharge pipe 4 will flow into the filter tube 13, and the impurities in the waste liquid will be blocked by the filter net 14, thereby achieving a filtering effect; when it is necessary to clean the impurities in the filter tube 13 in the later stage, it is only necessary to pull the filter tube 13 out of the filter cavity 901, which is simple and easy to operate.

[0030] Please refer to Figure 5 The upper surfaces of the plurality of filter cavities 901 are provided with bayonet holes 902 , and the outer walls of one end of the plurality of filter tubes 13 away from the filter screen 14 are slidably connected to the inner walls of the plurality of bayonet holes 902 .

[0031] More specifically, by providing the bayonet 902 , firstly, the external space occupied by the filter tube 13 can be reduced so that there is a gap between the filter tube 13 and the U-shaped connecting block 5 ; secondly, the filter tube 13 and the filter net 14 can be prevented from falling from the bottom of the filter cavity 901 .

[0032] Please refer to Figure 1 and Figure 4 The outer wall of the upper end of the U-shaped connecting block 5 is fixedly connected with a shielding plate 7, and a plurality of replacement openings 701 are penetrated through the upper surface of the shielding plate 7. The plurality of replacement openings 701 are respectively aligned with the plurality of bayonet openings 902 and have the same diameter, and the inner walls of the plurality of replacement openings 701 are hinged with a blocking cover 8.

[0033] More specifically, by providing the baffle plate 7, the replacement port 701 and the cover 8, several filter chambers 901 and filter components that are not performing filtering operations can be shielded to prevent external dust or impurities from falling in; and when the filter component needs to be cleaned and replaced, it is only necessary to open the cover 8 and pull out the filter component from the replacement port 701.

[0034] Please refer to Figure 4-Figure 6 The bottom surface of the outer wall of the replacement column 9 is rotatably connected with a recovery pipe 10, and the other end of the recovery pipe 10 is fixedly connected and communicated with the connecting pipe 6.

[0035] More specifically, because a large amount of ink impurities are accumulated on the filter screen 14, these impurities are likely to contain a certain amount of ink liquid. When the motor 11 rotates the filter tube 13 and the filter screen 14, it is likely that the ink will drip from the filter screen 14. Considering the need to save resources and make the filtering site cleaner and more hygienic, a recovery pipe 10 can be set up at this time to allow the remaining ink liquid to flow back into the connecting pipe 6.

[0036] Please refer to Figure 1-Figure 3 The number of the U-shaped connecting block 5, the connecting pipe 6, the rotating mechanism, the filtering assembly, the replacement column 9, the recovery pipe 10, the baffle plate 7 and the cover 8 is no less than one set.

[0037] More specifically, by arranging the above-mentioned components in multiple groups, the filtering effect can be better. It should be noted here that if the number of filtering components is more than two groups, the apertures of the multiple filter nets 14 can be arranged to become smaller from top to bottom, which can achieve better filtering effect.

[0038] Please refer to Figure 1-Figure 4 The rotating mechanism includes a support block 12 and a motor 11. One side of the support block 12 is fixedly connected to an outer wall of one side of the upper end of the U-shaped connecting block 5. The outer wall of the motor 11 is fixedly connected to the upper surface of the support block 12. The output shaft of the motor 11 passes through the support block 12 and is fixedly connected to the upper surface of the replacement column 9.

[0039] More specifically, when it is necessary to control the rotation of the replacement column 9, it is only necessary to turn on the switch of the motor 11 through an external controller. After the motor 11 is started, the output shaft drives the replacement column 9 to rotate, and then the filter assembly originally located between the U-shaped connecting blocks 5 can be rotated out; it should be noted here that: the motor 11 can be programmed in advance, that is, it stops each time it rotates to a certain angle. For example, if there are four filter chambers 901, the rotation angle can be set to 90 degrees each time.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
