Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid recovery, and more specifically, to a printing waste liquid recovery device. Background Art

[0002] Printing waste liquid refers to liquid waste such as wastewater, waste oil, and waste ink generated during the printing process of a printing press. In order to make the printing waste liquid more environmentally friendly when it is discharged, a recycling device is usually used to collect and harmlessly treat the printing waste liquid before discharge, thereby reducing harmful substances in the printing waste liquid and improving environmental protection effects.

[0003] Publication number CN218077270U discloses a printing waste liquid recycler, whose technical solution includes an installation box, a liquid inlet nozzle is fixedly connected to the top of the installation box, a filter component and a static component are arranged inside the installation box, the static component is located at the bottom of the filter component, the filter component includes a mounting frame, and an ultrafiltration membrane is arranged on the mounting frame.

[0004] The above technical solution, through the setting of the ultrafiltration membrane, can filter the impurities in the printing waste liquid and improve the purity of the printing waste liquid. At the same time, the setting of the toggle block can make the installation frame withdrawn from the inside of the installation box, so as to facilitate the cleaning of the ultrafiltration membrane. However, the printing waste liquid contains not only a large amount of impurities, but also a large amount of heavy metal ions. The heavy metal ions are highly toxic and cannot be degraded. The above technical solution, when filtering the printing waste liquid, only filters the impurities in the printing waste liquid through the ultrafiltration membrane, and does not set a structure for filtering the heavy metal ions in the printing waste liquid, resulting in a reduced filtering effect of the recovery device on the printing waste liquid, affecting the effect of the recovery device on the harmless treatment of the printing waste liquid.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a printing waste liquid recoverer, which solves the problem that when filtering the printing waste liquid, the heavy metal ions in the printing waste liquid cannot be filtered, resulting in reduced filtering effect of the printing waste liquid and affecting the effect of harmless treatment of the printing waste liquid.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a printing waste liquid recoverer, including a body, wherein chamber one and chamber two are arranged in the body, a heating tube is fixedly connected to the bottom of chamber one, a heat conducting plate is fixedly connected to the heating tube, a partition is fixedly connected to the heat conducting plate, a liquid inlet pipe which is mutually conductive with chamber one is fixedly connected to the side of the body away from the partition, a delivery pipe is fixedly connected to the side of the body close to the partition, both ends of the delivery pipe are respectively mutually conductive with chamber one and chamber two, a delivery component for delivering waste liquid to the delivery pipe is arranged in chamber one, a filtering component for filtering heavy metal ions in printing waste liquid and a sampling component for sampling waste liquid are arranged in chamber two.

[0008] By adopting the above technical scheme, when it is necessary to harmlessly treat the printing waste liquid, the printing waste liquid is introduced into chamber one through the liquid inlet pipe, and the printing waste liquid is driven to accumulate on the heat conduction plate, and then the heating tube is started to drive the heating tube to start heating, and at the same time, the heat generated by the heating tube is absorbed by the heat conduction plate, and the printing waste liquid in chamber one is heated. At this time, the printing waste liquid in chamber one is affected by the heat, so that the moisture in the printing waste liquid begins to evaporate, and the water vapor generated by the evaporated printing waste liquid condenses on the conveying component, and the condensed printing waste liquid is conveyed to the conveying pipe through the conveying component. By setting the heating tube, the printing waste liquid can be evaporated, and the impurities and moisture in the printing waste liquid can be separated from each other, thereby improving the filtering effect of the printing waste liquid. When the printing waste liquid is conveyed to the conveying pipe, the printing waste liquid The waste liquid will enter the second chamber through the delivery pipe, and the heavy metal ions in the printing waste liquid will be filtered through the filtering component. After the printing waste liquid is filtered, the printing waste liquid can be sampled through the sampling component to determine whether the filtered printing waste liquid meets the qualified discharge standard. When the printing waste liquid meets the qualified discharge standard, the printing waste liquid will be discharged from the second chamber to the outside, so as to complete the effect of harmless treatment of the printing waste liquid. The printing waste liquid is evaporated by the heating tube, so that the impurities and water in the printing waste liquid can be separated from each other, and some heavy metal ions and printing waste liquid can also be separated from each other. Then, the filtering component can be used to filter the heavy metal ions inside the printing waste liquid, so as to reduce the content of heavy metal ions in the printing waste liquid and improve the effect of harmless treatment of the printing waste liquid.

[0009] The utility model is further configured as follows: the conveying assembly includes a plurality of guide plates fixedly connected to chamber one, a plurality of through holes are opened on the guide plates, a plurality of the guide plates are inclined toward the partition, and there is a spacing between two adjacent guide plates.

[0010] By adopting the above technical scheme, when the printing waste liquid in chamber one is heated and evaporated, the water vapor generated by the evaporated printing waste liquid will float upward and contact with a number of guide plates at the same time. When the water vapor contacts the guide plates, the printing waste liquid will be affected, condense on the guide plates, and begin to flow in the direction of the inclination of the guide plates. When the printing waste liquid condensed on the guide plates moves to the lowest point of the guide plates, the printing waste liquid will drip downward between the conveying pipe and the partition, thereby achieving the effect of conveying the water vapor generated by the printing waste liquid. By setting a number of through holes, the condensation speed of the evaporated printing waste liquid can be increased, thereby improving work efficiency.

[0011] The utility model is further configured as follows: the filter assembly includes a filter box which is slidably connected to the second chamber near the delivery pipe and opens upward, the side wall of the body is provided with a through groove for the filter box to slide, a plurality of filter frames are detachably connected to the filter box, a plurality of water seepage holes are provided at the bottom of a plurality of the filter frames, activated carbon is provided on a plurality of the filter frames, and a liquid outlet is provided on the side of the filter box away from the delivery pipe.

The activated carbon can adsorb the heavy metal ions in the printing waste liquid, and then starts to flow downward through the seepage holes, thereby achieving the effect of filtering the heavy metal ions in the printing waste liquid. After the printing waste liquid is filtered, it can flow out of the filter box through the liquid outlet at the bottom of the filter box, thereby achieving the effect of filtering the heavy metal ions inside the printing waste liquid. At the same time, through the setting of the through groove, it is easy to separate the filter box and the body, and it is convenient to replace the activated carbon on the filter frame.

[0014] By adopting the above technical solution, when the activated carbon on the filter frame needs to be replaced, the filter frame located above is lifted, and then the rotating plate is driven to start rotating, and the rotating plate is driven to enter the placement groove, and then the filter frame located below is lifted and taken out. After the activated carbon in the filter frame is replaced, the rotating plate and the placement groove are separated from each other and contacted with the limit block. At this time, the rotating plate and the bottom of the filter box are arranged parallel to each other, and then the filter frame is placed on the rotating plate, thereby completing the effect of replacing the activated carbon.

[0015] The utility model is further configured as follows: the sampling component includes a sampling port opened on the side wall of the body, and a plurality of elastic membranes are fixedly connected to a side of the sampling port close to the second chamber.

[0016] By adopting the above technical solution, when it is necessary to sample the printing waste liquid in chamber two, the dropper is inserted into the sampling port and pressure is applied. At this time, the elastic membrane on the sampling port begins to deform under the influence of pressure, driving the dropper to be smoothly inserted into chamber two and collect the elastic membrane in chamber two. After the collection is completed, the dropper is pulled out from the sampling port. At this time, the elastic membrane cancels the restriction and begins to recover its deformation, preventing the printing waste liquid from flowing out through the sampling port, thereby achieving the effect of sampling the printing waste liquid in chamber two.

[0017] The utility model is further configured as follows: the side wall of the machine body is fixedly connected with a material conveying pipe which is in conduction with the second chamber.

[0018] By adopting the above technical solution, after the sampling of printing waste liquid is completed, chemical reagents can be added to chamber 2 through the feed pipe according to the sampling results, and the printing waste liquid can be neutralized by the chemical reagents, thereby improving the effect of harmless treatment of the printing waste liquid.

At the same time, the heat generated by the heating tube 4 is absorbed by the heat conduction plate 5, and the printing waste liquid in chamber 2 is heated. At this time, the printing waste liquid in chamber 2 is affected by the heat, so that the water in the printing waste liquid begins to evaporate.

[0033] The water vapor generated by the evaporated printing waste liquid will condense on the conveying component, and the condensed printing waste liquid will be conveyed to the conveying pipe 8 through the conveying component. By setting the heating tube 4, the printing waste liquid can be evaporated so that the impurities and water in the printing waste liquid are separated from each other, thereby improving the filtering effect of the printing waste liquid. When the printing waste liquid is conveyed to the conveying pipe 8, the printing waste liquid will enter the chamber 2 3 through the conveying pipe 8, and the heavy metal ions in the printing waste liquid will be filtered through the filtering component. After the printing waste liquid is filtered, the printing waste liquid can be sampled through the sampling component to judge Whether the printing waste liquid after filtration meets the qualified discharge standard, when the printing waste liquid meets the qualified discharge standard, the printing waste liquid is discharged from the chamber 2 3 to the outside, so as to complete the effect of harmless treatment of the printing waste liquid, and the printing waste liquid is evaporated by the heating tube 4, so that the impurities and water in the printing waste liquid can be separated from each other, and part of the heavy metal ions and the printing waste liquid can also be separated from each other, and then the filtering component can be used to filter the heavy metal ions in the printing waste liquid, so as to reduce the content of heavy metal ions in the printing waste liquid and improve the effect of harmless treatment of the printing waste liquid.

When the steam and the guide plates 9 are in contact, the printing waste liquid will be affected, condensed on the guide plates 9, and begin to flow along the inclination direction of the guide plates 9. When the printing waste liquid condensed on the guide plates 9 moves to the lowest point of the guide plates 9, the printing waste liquid will drip downward between the conveying pipe 8 and the partition 6, thereby achieving the effect of conveying the printing waste liquid. By setting the plurality of through holes 10, the condensation speed of the evaporated printing waste liquid can be increased, thereby improving the work efficiency.

[0035] like Figure 1-Figure 4 As shown, the filter assembly includes a filter box 11 which is slidably connected to the side of the chamber 2 3 near the delivery pipe 8 and has an upward opening. The side wall of the body 1 is provided with a through groove 12 for the filter box 11 to slide. A plurality of filter frames 13 are detachably connected to the filter box 11. A plurality of water seepage holes 14 are provided at the bottom of the plurality of filter frames 13. Activated carbon 15 is provided on the plurality of filter frames 13. A liquid outlet 16 is provided on the side of the filter box 11 away from the delivery pipe 8. When the printing waste liquid enters the chamber 2 3 through the delivery pipe 8, the printing waste liquid will enter the filter box 11 and interact with the activated carbon in the filter frame 13. The carbons 15 are in contact with each other, and the heavy metal ions in the printing waste liquid can be adsorbed by the activated carbon 15, and then flow downward through the seepage hole 14, so as to achieve the effect of filtering the heavy metal ions in the printing waste liquid. After the printing waste liquid is filtered, it can flow out of the filter box 11 through the liquid outlet 16 at the bottom of the filter box 11, so as to achieve the effect of filtering the heavy metal ions inside the printing waste liquid. At the same time, through the setting of the through groove 12, it is convenient to separate the filter box 11 and the body 1, so as to facilitate the replacement of the activated carbon 15 on the filter frame 13.

[0037] like Figure 1-Figure 4 As shown, the sampling component includes a sampling port 20 opened on the side wall of the body 1, and a plurality of elastic membranes 21 are fixedly connected to the side of the sampling port 20 close to the chamber 2 3. When the elastic membrane 21 is in a natural state, the plurality of elastic membranes 21 contact each other, and a dropper 22 is slidably connected to the inner wall of the sampling port 20. When it is necessary to sample the printing waste liquid in the chamber 2 3, the dropper 22 is inserted into the sampling port 20 and pressure is applied. At this time, the elastic membrane 21 on the sampling port 20 begins to deform under the influence of pressure, driving the dropper 22 to be smoothly inserted into the chamber 2 3 and collect the elastic membrane 21 in the chamber 2 3. After the collection is completed, the dropper 22 is pulled out from the sampling port 20.

Filters 26 are fixedly connected to both ends of the delivery pipe 8, respectively, which can filter the printing waste liquid and further improve the filtering effect of the printing waste liquid.

[0039] The utility model is used as follows during normal use: when the printing waste liquid needs to be harmlessly treated, the printing waste liquid is introduced into the chamber 2 through the liquid inlet pipe 7, and the printing waste liquid is driven to accumulate on the heat conduction plate 5, and then the heating tube 4 is started to drive the heating tube 4 to start heating. At the same time, the heat generated by the heating tube 4 is absorbed by the heat conduction plate 5, and the printing waste liquid in the chamber 2 is heated. At this time, the printing waste liquid in the chamber 2 is affected by the heat, so that the water in the printing waste liquid begins to evaporate.

[0040] The water vapor generated by the evaporated printing waste liquid will float upward and contact with several guide plates 9 at the same time. When the water vapor contacts the guide plates 9, the printing waste liquid will be affected, condensed on the guide plates 9, and start to flow along the inclination direction of the guide plates 9. When the printing waste liquid condensed on the guide plates 9 moves to the lowest point of the guide plates 9, the printing waste liquid will drip downward between the conveying pipe 8 and the partition 6. When the printing waste liquid is conveyed to the conveying pipe 8, the printing waste liquid will enter the chamber 2 3 through the conveying pipe 8. At the same time, the printing waste liquid will enter the filter box 11 and contact with the activated carbon 15 in the filter frame 13. The activated carbon 15 can adsorb the heavy metal ions in the printing waste liquid, and then start to flow downward through the seepage holes 14, so as to achieve the effect of filtering the heavy metal ions in the printing waste liquid. After the printing waste liquid is filtered, it can flow out of the filter box 11 through the liquid outlet 16 at the bottom of the filter box 11.

[0041] After the printing waste liquid is filtered, the dropper 22 is inserted into the sampling port 20 and pressure is applied. At this time, the elastic membrane 21 on the sampling port 20 begins to deform under the influence of pressure, driving the dropper 22 to be smoothly inserted into the chamber 2 3 and collect the elastic membrane 21 in the chamber 2 3. After the collection is completed, the dropper 22 is pulled out from the sampling port 20 to determine whether the filtered printing waste liquid meets the qualified discharge standard. When the printing waste liquid meets the qualified discharge standard, the printing waste liquid is discharged from the chamber 2 3 to the outside, thereby completing the effect of harmless treatment of the printing waste liquid.
