Description

Technical Field

[0001] This invention relates to the field of water circulation and purification technology, specifically to a printing plate processing water circulation treatment device. Background Technology

[0002] Plate making and developing are the most commonly used processes in the printing industry today. After developing, developing solution and other impurities remain on the printing plate. These residues can ruin the effect of the next developing cycle, affecting the quality of printed products and production efficiency. Therefore, after each printing cycle, a plate setter is needed to set the plate. This process requires a large amount of clean water to rinse the plate and remove the residue. The wastewater generated after plate setting is enormous, and because it contains pollutants such as developing solution, it becomes a major source of environmental pollution. Furthermore, a large amount of plate setting water is discharged as wastewater every year, resulting in significant waste. Therefore, how to effectively recycle and reuse plate setting water is a problem that printing companies need to solve today.

[0003] An existing plate-developing water circulation treatment system (patent application number: CN202020430950.9) includes a housing with at least one inlet. A first treatment tank is located inside the housing, and the inlet is connected to the first treatment tank. A first dosing pump for adding flocculant to the first treatment tank is installed inside the first treatment tank. Several funnel openings for discharging the treated plate-developing water from the first treatment tank are located at the bottom of the first treatment tank, with the larger diameter end of the funnel opening facing upwards. An ultrafiltration membrane is installed below the first treatment tank. The solution for the ultrafiltration membrane is simply added dropwise to the plate-developing water, resulting in incomplete reaction between the solution and the plate-developing water. To solve this technical problem, a plate-developing water circulation treatment device is proposed. Summary of the Invention

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figures 1 to 7 The present invention provides a structural diagram of a plate-developing water circulation treatment device according to Embodiment 1. The plate-developing water circulation treatment device includes: a chemical mixing tank 10, a constant pressure chemical tank 20, a settling tank 30, and a filter tank 40. The chemical mixing tank 10 is installed on the settling tank 30, and the bottom of the chemical mixing tank 10 is connected to the top of the settling tank 30. The upper part of the side wall of the settling tank 30 is connected to the top of the filter tank 40. The constant pressure chemical tank 20 is used to add chemicals to the input plate-developing water. The constant pressure chemical tank 20 is a constant pressure chemical tank that provides chemicals to the chemical mixing tank 10. The settling tank 30 is used to store the plate-developing water after the chemical addition is completed so that it can undergo a series of reactions. The filter tank 40 is used to filter and purify the plate-developing water after the reaction is completed.

[0035] Because existing technologies suffer from uneven dispersion of chemicals and printing fluid during the dosing process, a dosing device 103 is proposed to solve this problem. The chemical mixing tank 10 has an inlet 102 at its top and a dosing device 103 inside. The dosing device 103 includes a central column 104 fixedly installed in the middle of the chemical mixing tank 10. A central shaft 107 is rotatably mounted on the central column 104. Several mounting shafts 112 are arranged in an array outside the central shaft 107. The mounting shafts 112 are raised and each mounting shaft 112 is equipped with an axial flow blade 111. Several spray holes are evenly arranged on the axial flow blade 111. The end of the axial flow blade 111 away from the mounting shaft 112 is close to the side wall of the chemical mixing tank 10.

[0036] During processing, the plate-developing water is fed into the chemical mixing tank 10 through the inlet 102. When the plate-developing water passes through the axial flow blades 111, the impact of the water flow drives the intermediate shaft 107 to rotate. At the same time, the chemical spraying holes on the axial flow blades 111 spray out chemical solution, which mixes with the flowing plate-developing water. This allows the chemical solution to be dispersed during rotation and mixed with the passing chemical solution, improving the mixing effect. This invention can effectively recycle plate-developing water, reduce water pollution, and is environmentally friendly.

[0037] In order to automatically adjust the supply of chemicals according to the water flow rate of the printing plate, the intermediate shaft 107 is elastically mounted on the intermediate column 104. A chemical delivery water column 106 is fixedly installed in the middle position inside the intermediate column 104. The upper end of the intermediate shaft 107 is rotatably sleeved on the bottom of the chemical delivery water column 106. A first chemical delivery channel 115 is provided inside the chemical delivery water column 106, and a second chemical delivery channel 110 is provided inside the intermediate shaft 107. The input end of the first chemical delivery channel 115... The infusion structure is connected to the constant-pressure drug tank 20, which provides constant-pressure drug to the first drug delivery channel 115. A first output port 116 is provided on the side wall of the drug delivery column 106, communicating with the first drug delivery channel 115. A first input port 117 is provided on the inner wall of the intermediate shaft 107, communicating with the interior of the second drug delivery channel 110, and located above the first output port 116. Specifically, when the flow rate of the flushing water increases, the impact force on the axial flow blades 111 increases, causing the axial flow blades 111 to descend, thus increasing the overlap area between the first input port 117 and the first output port 116, resulting in more drug being sprayed through the spray nozzle. This achieves automatic adjustment of the drug dosage based on the flow rate.

[0038] In some embodiments, a rotating ring 108 is rotatably disposed on the intermediate column 104. The rotating ring 108 is sleeved on the outside of the intermediate shaft 107. A plurality of elastic telescopic rods 109 are fixedly mounted on the rotating ring 108, and the ends of the elastic telescopic rods 109 away from the rotating ring 108 are fixedly mounted on the intermediate shaft 107. This allows the intermediate shaft 107 to be elastically and rotatably mounted in the intermediate column 104. Specifically, the rotating ring 108 is rotatably mounted on the bottom of the intermediate column 104 and is concentric with the intermediate column 104. The rotating ring 108 can be rotatably mounted on the intermediate column 104 via bearings. The elastic telescopic rods 109 are existing technology.

[0039] In some embodiments, to ensure more thorough mixing of the chemical solution with the plate-developing fluid when the flow rate increases, a mounting shaft 112 is rotatably mounted in an intermediate shaft 107. One end of the mounting shaft 112 is inserted into the second drug delivery channel 110. An adjustment mechanism is provided on the intermediate column 104 to automatically adjust the tilt angle of the axial flow blades 111 according to the flow rate. The larger the flow rate, the smaller the tilt angle of the axial flow blades 111. Thus, when the flow rate increases, the impact force of the plate-developing fluid on the axial flow blades 111 increases, while the tilt angle decreases, increasing the rotational driving force and the rotational speed of the axial flow blades 111. This further increases the collision opportunities between the plate-developing fluid and the axial flow blades 111, slowing down the flow rate of the plate-developing fluid and increasing the possibility of atomization. This allows the chemical solution sprayed from the axial flow blades 111 to mix well with the plate-developing fluid. The increased rotational speed of the axial flow blades 111 increases the velocity of the sprayed chemical solution, increasing collisions during mixing and resulting in a more uniform mixture.

[0040] In some embodiments, the adjustment mechanism includes a first elastic element 118 fixedly sleeved on the mounting shaft 112 and a plurality of racks 114 arranged in an array at the bottom of the rotating ring 108, wherein the racks 114 mesh with adjacent first elastic elements 118. Thus, when the intermediate shaft 107 is at different heights under different flow conditions due to the action of the axial flow blades 111, the racks 114 cause the gears 113 to drive the mounting shaft 112 and the axial flow blades 111 to deflect, thereby automatically adjusting the angle of the axial flow blades 111 according to the flow rate.

[0041] like Figure 2 and Figure 3 As shown, in some embodiments, a first elastic element 118 is sleeved on the outer side of the mounting shaft 112. The two ends of the first elastic element 118 are respectively fixedly mounted on the mounting shaft 112 and the intermediate shaft 107, so that the mounting shaft 112 is elastically rotated and mounted on the intermediate shaft 107.

[0042] like Figure 3As shown, in some embodiments, a third drug delivery channel 120 is also provided between the mounting shaft 112 and the axial flow blade 111. The third drug delivery channel 120 is used to deliver the drug in the second drug delivery channel 110 to the spray hole on the surface of the corresponding axial flow blade 111.

[0043] A number of support columns 105 are fixedly connected to the outer side of the intermediate column 104, and the end of the support column 105 away from the intermediate column 104 is fixedly connected to the inner wall of the medicine mixing tank 10.

[0044] like Figure 2 As shown, in some embodiments, a coarse filter 101 is also provided inside the medicine mixing tank 10. The coarse filter 101 is located above the medicine dosing device 103. The coarse filter 101 has a raised design in the middle to increase the filtration area for preliminary filtration of the flushing water.

[0045] In some embodiments, the axial flow blades 111 are arranged in an array of arc-shaped protrusions 119, each arc-shaped protrusion 119 having at least one spray hole. When the printing fluid passes through the arc-shaped protrusions 119, it forms a water flow with a central depression. At this time, the sprayed liquid from the spray hole on the arc-shaped protrusion 119 comes into contact with the printing fluid in the depression, allowing the liquid to be enveloped by the printing fluid and mix well. The spray hole can be located on the end of the arc-shaped protrusion 119 facing away from the water flow direction.

[0046] like Figure 2 As shown, in some embodiments, the top of the filter box 40 is connected to the upper side wall of the settling box 30 via a connecting pipe 401. Inside the filter box 40, from top to bottom, are arranged an ultrafiltration membrane plate 402, a purification core plate 403, and an ink filter plate 404. The bottom of the filter box 40 also has a discharge port 405. After the plate-developing water has settled in the settling box 30, it enters the filter box 40 through the connecting pipe 401, passes through the ultrafiltration membrane plate 402, the purification core plate 403, and the ink filter plate 404 in sequence, and is then discharged through the discharge port 405. This process circulates the plate-developing water, meeting the requirements for reuse. The ultrafiltration membrane plate 402, the purification core plate 403, and the ink filter plate 404 are respectively attached to the four sides of the inner wall of the filter box 40.

[0047] In some embodiments, the bottom of the settling box 30 is also provided with a drain outlet.

[0048] Example 2

[0049] Please see Figures 8-9In Embodiment 2, a notch 121 is provided on one side of the bottom of the third drug delivery channel 120. A disturbance leaf 122 is disposed inside the notch 121. A mounting shaft 123 passes through the disturbance leaf 122, and its two ends are rotatably mounted on adjacent sidewalls of the notch 121. The mounting shaft 123 is elastically rotatably mounted within the notch 121. A swing mechanism is provided between the drug mixing tank 10 and the disturbance leaf 122 to drive the disturbance leaf 122 to swing up and down as the third drug delivery channel 120 rotates. This allows the water flow direction to be continuously changed when impacted by the plate-developing water, improving the mixing effect of the drug and the plate-developing water.

[0050] In some embodiments, the arc-shaped protrusion 119 can be disposed on the water-facing surface of the disturbance blade 122, and the spray hole can be disposed on the water-repellent end of the arc-shaped protrusion 119.

[0051] In some embodiments, a torsion spring is sleeved on the outer side of the mounting shaft 123, and the two ends of the torsion spring are respectively fixedly mounted on the mounting shaft 123 and the third drug delivery channel 120, so that the disturbance leaf 122 is elastically rotated and mounted on the third drug delivery channel 120.

[0052] In some embodiments, the oscillating mechanism includes a mating ring 124, which is elastically mounted vertically in the chemical mixing tank 10 and sleeved on the outside of the third drug delivery channel 120. A gear 126 is fixedly sleeved on the outside of the mounting shaft 123. A plurality of toothed segments 127 are arranged in an array on the upper side of the mating ring 124, and the toothed segments 127 are arranged on the track of the gear 126. Thus, when the mounting shaft 123 rotates with the third drug delivery channel 120, it drives the disturbance blade 122 to oscillate as it passes the toothed segments 127, thereby continuously changing the angle of the toothed segments 127 and improving the mixing effect of the printing fluid and the chemical solution. The mating ring 124 is mounted vertically on the chemical mixing tank 10, so that when the third drug delivery channel 120 descends, the mounting shaft 123 or the gear 126 abuts against the mating ring 124, allowing the mating ring 124 to also descend, thus adapting to the oscillation requirements at different positions.

[0053] In some embodiments, the deflection direction of the disturbance leaf 122 is opposite to the deflection direction of the third drug delivery channel 120, thereby inducing a reversal of the water flow.

[0054] In some embodiments, an elastic telescopic rod 125 is fixedly installed at the bottom of the toothed section 127, and the end of the elastic telescopic rod 125 away from the toothed section 127 is fixedly installed on the medicine mixing tank 10. The elastic telescopic rod 125 is prior art and will not be described in detail here.

[0055] The working principle of this invention is:

[0056] In use, the rinsing water is fed into the chemical mixing tank 10 through the inlet 102, and then undergoes preliminary filtration through the coarse filter 101. It then impacts several axial flow blades 111, which rotate under the impact of the water flow. At the same time, the constant pressure chemical tank 20 provides chemical solution to the spray holes on the arc-shaped protrusions 119 on the axial flow blades 111 through the chemical delivery water column 106 and the intermediate shaft 107, so that the chemical solution and the rinsing water flowing through are evenly mixed. After the rinsing water is mixed, it enters the settling tank 30 for settling. Then, the rinsing water in the upper layer of the settling tank 30 enters the filter tank 40 through the connecting pipe 401. Therefore, after being processed by the ultrafiltration membrane plate 402, the purification core plate 403 and the ink filter plate 404, the rinsing water is circulated through the discharge port 405. If the flow rate through the coarse filter 101 changes during the treatment process, the impact force on the axial flow blades 111 changes. At this time, the height of the intermediate shaft 107 changes under elastic action, thus changing the overlap area between the first inlet 117 on the intermediate shaft 107 and the first outlet 116 on the drug delivery column 106. The greater the flow rate, the greater the impact force on the axial flow blades 111, and the larger the overlap area between the first inlet 117 and the first outlet 116. This allows for automatic adjustment of the drug supply based on the flow rate. Simultaneously, when the flow rate changes, the impact force on the axial flow blades 111 also changes. When the height of the axial flow blade 111 changes, the height of the gear 113 mounted on the rotating shaft 112 also changes, but the height of the rack 114 remains unchanged. This causes the gear 113 to change the angle of the axial flow blade 111 under the action of the rack 114. The impact force of the rinsing water on the axial flow blade 111 increases with the increase of the flow rate, thereby increasing the rotational speed of the axial flow blade 111. The increase in flow rate further increases the collision opportunity between the rinsing water and the axial flow blade 111, which slows down the flow rate of the rinsing water and increases the possibility of atomization, so that the chemical sprayed on the axial flow blade 111 can be well mixed with the rinsing water.
