[0002] In the ink manufacturing, printing and packaging industries, the production process continuously generates ink waste liquid containing corrosive components such as sulfuric acid, hydrochloric acid and organic acids. This waste liquid also contains solid pollutants such as ink resin debris, pigment particles and fiber impurities, which constitute a complex system of hazardous chemicals and hazardous waste.

[0003] However, the current industry mostly uses a crude method of storing waste ink acid in "ordinary plastic buckets + simple sheds" or uses traditional corrosive liquid storage equipment. It has not been specifically designed for the characteristics of waste ink acid, which are "highly corrosive, contain impurities, and are prone to leakage", which will cause certain pollution to the surrounding environment. Therefore, it needs to be improved. Utility Model Content

[0015] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] This utility model provides an acid storage device for waste ink liquid, such as... Figure 1-4 As shown, the ink waste acid storage device includes: an inner tank 2 disposed inside the prefabricated shell 1 for storing ink waste acid; a protective shell 3 disposed outside the inner tank 2 for preventing leakage; a conduit 5 fixedly connected to the inner tank 2, the inlet end of the conduit 5 being fixedly connected to a housing 4; a plurality of filter plates 6 disposed inside the housing 4; an inlet pipe 7 fixedly connected to the top of the housing 4; and a drainage mechanism disposed inside the prefabricated shell 1 for draining the liquid from the inner tank 2 and the protective shell 3.

[0017] In this embodiment, during use, the ink waste acid to be stored is first introduced into the tank 4 through the inlet pipe 7. The waste liquid flows through several filter plates 6 in the tank 4. The filter plates 6 are made of acid-resistant and corrosion-resistant material, which can filter impurities such as pigment particles and resin debris mixed in the waste liquid. The filtered ink waste acid enters the inner tank 2 through the conduit 5. The inner tank 2 is set in the prefabricated shell 1 and is used to store the filtered waste acid. At the same time, the protective shell 3 outside the inner tank 2 can collect any leakage liquid and prevent the leakage liquid from directly contacting the inside of the prefabricated shell 1. When it is necessary to discharge the stored waste liquid in the inner tank 2 or the leakage liquid in the protective shell 3, the drainage mechanism in the prefabricated shell 1 is activated. The drainage mechanism can discharge the two liquids separately, completing the storage and subsequent drainage process of the ink waste acid.

[0018] The device uses the inner tank 2 and the protective shell 3 together. The inner tank 2 serves as the main storage component to receive the filtered ink waste acid. The protective shell 3 is fitted outside the inner tank 2 and can collect the leakage caused by damage or sealing failure of the inner tank 2, preventing the leakage from directly penetrating into the prefabricated shell 1 or the external environment, thus reducing pollution to the surrounding environment. At the same time, the prefabricated shell 1 provides external support and protection for the overall structure, further reducing the risk of waste acid leakage pollution. The enclosure 4 and filter plate 6 enable the pretreatment filtration function of ink waste liquid before acid storage. The acid and corrosion resistant properties of filter plate 6 can adapt to the corrosive environment of waste liquid acid. It intercepts impurities before the waste liquid enters the inner tank 2, reduces the deposition of impurities at the bottom of the inner tank 2, reduces the local corrosion of the inner wall of the inner tank 2, and at the same time avoids impurities clogging the drain pipe or damaging the drain mechanism components during the subsequent draining process, thus extending the overall service life of the device. The drainage mechanism can drain the normal storage waste liquid in the inner tank 2 and the leakage liquid in the protective shell 3 separately without the need for additional manual tools or third-party equipment, which simplifies the drainage operation process, reduces the direct contact between operators and waste acid, and reduces the risk of personnel contact corrosion. At the same time, the drainage mechanism is integrated into the prefabricated shell 1 and works in coordination with the overall structure of the device, which improves the convenience of operation and facilitates centralized control of the drainage process.

[0019] In a further preferred embodiment of the present invention, the draining mechanism includes: a pump body 8 disposed within the precast shell 1; a tap 9 fixedly connected to the inlet end of the pump body 8, the inlet end of the tap 9 being fixedly connected to a connecting pipe, the inlet end of the connecting pipe being fixedly connected to the corresponding inner tank 2 and the protective shell 3 respectively; and a valve 11 disposed on the connecting pipe for controlling the opening and closing of the pipeline.

[0020] In this embodiment, when it is necessary to discharge the stored waste liquid in the inner tank 2, first open the valve 11 on the connecting pipe connected to the inner tank 2, and then start the pump body 8 in the prefabricated shell 1; the pump body 8 generates negative pressure suction, and forms a passage with the corresponding connecting pipe through the tap 9, so that the waste liquid in the inner tank 2 enters the pump body 8 through the connecting pipe and the tap 9 in sequence, and is finally discharged by the pump body 8; if it is necessary to discharge the leakage liquid in the protective shell 3, close the valve 11 connected to the inner tank 2, open the valve 11 on the connecting pipe connected to the protective shell 3, and repeat the above operation of starting the pump body 8, so that the leakage liquid in the protective shell 3 can be sucked into the pump body 8 and discharged through the corresponding connecting pipe and the tap 9, so as to achieve the separate discharge of different liquids; The drainage mechanism, through the cooperation of the tap 9 and multiple sets of connecting pipes and valves 11, can control the drainage passages of the inner tank 2 and the protective shell 3 respectively. The operator only needs to switch the on and off state of the valves 11 to achieve the separate discharge of normally stored waste liquid and leakage liquid, without disassembling or adjusting the drainage pipeline, which simplifies the drainage operation steps and improves the flexibility of the drainage operation. The pump body 8 is integrated into the precast shell 1 as a power source. Compared with the traditional manual drainage method, it can quickly form a stable drainage force and accelerate the discharge efficiency of waste liquid and leakage liquid. At the same time, the connecting pipe and the tap 9 are fixed connection structures, which reduces the operation of temporary connection pipelines, reduces the possibility of liquid leakage during the drainage process, and ensures the stability of the drainage process. The valve 11 can cut off the connection pipe passage when the liquid is not draining, so as to prevent the waste liquid in the inner tank 2 or the leakage liquid in the protective shell 3 from entering the tap 9 or pump body 8 during non-operation periods. This reduces the long-term contact corrosion of the internal components of the tap 9 and pump body 8 by the liquid, extends the service life of each component of the draining mechanism, and reduces equipment maintenance costs.

[0021] In a further preferred embodiment of the present invention, a water spray pipe 12 is fixedly installed inside the protective shell 3, and the water inlet end of the water spray pipe 12 is fixedly connected to a water inlet pipe 13 for connecting to a water supply device.

[0022] In this embodiment, when the protective shell 3 contains leaked liquid, or when it needs to be cleaned after multiple leaked liquid discharges, the free end of the water inlet pipe 13 is first connected to the external water supply equipment; the water supply equipment is started, and clean water enters the spray pipe 12 fixedly installed inside the protective shell 3 through the water inlet pipe 13; the spray pipe 12 sprays clean water onto the inner wall and bottom of the protective shell 3 in the form of a spray to rinse the residual acid and impurities attached to the inner wall; during the rinsing process, the drainage mechanism and the drainage passage corresponding to the protective shell 3 are opened, so that the rinsing sewage enters the pump body 8 through the connecting pipe and the tap 9, and is finally discharged from the protective shell 3 by the pump body 8, completing the cleaning operation inside the protective shell 3.

[0023] In a further preferred embodiment of the present invention, the inner wall of the precast shell 1 is provided with an anti-seepage layer 14, and the outlet end of the pump body 8 is fixedly connected to an outlet pipe 10, the outlet end of the outlet pipe 10 extending out of the precast shell 1.

[0024] In this embodiment, the anti-seepage layer 14 on the inner wall of the precast shell 1 can block possible liquid leakage inside the precast shell 1 (such as leakage caused by damage to the protective shell 3), prevent liquid from penetrating to the outside of the precast shell 1, reduce pollution to the ground where the device is placed and the surrounding environment, and at the same time provide additional protection for components such as the pump body 8 and connecting pipes inside the precast shell 1, reducing the risk of liquid contact corrosion of these components. The design of the outlet pipe 10 extending beyond the precast shell 1 eliminates the need to temporarily open an outlet on the precast shell 1 during the drainage process. The outlet pipe 10 can be directly connected to external equipment, simplifying the equipment connection steps during drainage. At the same time, external collection containers or treatment equipment can be set away from the precast shell 1, reducing the frequency of operations by personnel around the precast shell 1, lowering the safety risk of personnel coming into contact with acid, and improving the convenience of drainage operations.

[0025] In a further preferred embodiment of the present invention, a level gauge 15 for measuring liquid level is provided on the top of the inner tank 2, a visual liquid level window is provided on one side of the inner tank 2, and an observation port is provided on one side of the prefabricated shell 1.

[0026] In this embodiment, during the process of injecting waste ink acid into the inner tank 2, the liquid level data inside the tank can be obtained in real time through the level gauge 15 installed on the top of the inner tank 2 to determine whether the waste acid has reached the preset storage amount. The level gauge 15 is an electronic infrared type, which adopts a non-contact measurement method and does not need to be in direct contact with the waste acid. This can effectively avoid the corrosion of the level gauge probe by strong acid and extend the service life of the level gauge 15. When it is necessary to visually check the state of the waste acid inside the inner tank 2 (such as whether there is stratification or impurity deposition), the operator can observe the visual liquid level window on the side of the inner tank 2 through the observation port on one side of the prefabricated shell 1. The observation window can clearly show the actual state of the liquid inside the tank. During daily storage, the liquid level changes can also be monitored periodically through the level gauge 15. The situation inside the tank can be viewed in conjunction with the observation port and the liquid level window to keep track of the storage status of the inner tank 2 in a timely manner.

[0027] In a further preferred embodiment of the present invention, an inspection port is provided on one side of the housing 4, and a detachable sealing plate 16 is provided inside the inspection port. A screw is provided on the sealing plate 16, and the screw is threadedly connected to the housing 4.

[0028] In this embodiment, when the filter plate 6 inside the housing 4 needs to be replaced or the inside of the housing 4 needs to be cleaned and maintained, first shut off the liquid inlet operation of the liquid inlet pipe 7 to ensure that there is no waste liquid flowing inside the housing 4; then use a tool to unscrew the screws on the sealing plate 16 to disengage the screws from the threaded connection of the housing 4; remove the detachable sealing plate 16 to expose the inspection port on one side of the housing 4; replace the filter plate 6 inside the housing 4 or clean the inner wall of the housing 4 through the inspection port; after completing the maintenance operation, reinsert the sealing plate 16 into the inspection port, align the screws with the threaded holes and screw them in until the sealing plate 16 fits tightly with the housing 4, restoring the sealing state of the housing 4, and then the ink waste acid can be injected again through the liquid inlet pipe 7 for filtration.

[0029] In a further preferred embodiment of the present invention, sliding groove plates are symmetrically fixedly installed on the inner wall of the housing 4, and the sliding groove plates are used to install the filter plates 6.

[0030] In this embodiment, when installing the filter plate 6, first, through the inspection port on one side of the housing 4 (the sealing plate 16 needs to be removed in advance), align the two sides of the filter plate 6 with the symmetrically fixed sliding groove plate on the inner wall of the housing 4; slowly push the filter plate 6 along the groove of the sliding groove plate until the filter plate 6 is completely embedded in the sliding groove plate, thus achieving the positioning and installation of the filter plate 6 in the housing 4; when it is necessary to replace the filter plate 6, pinch the edge of the filter plate 6 from the inspection port, pull out the old filter plate 6 in the opposite direction along the groove of the sliding groove plate, and then push the new filter plate 6 into the sliding groove plate according to the above steps; after completing the installation or replacement of the filter plate 6, reinstall the sealing plate 16 and tighten the screws, and then inject the ink waste acid through the liquid inlet pipe 7, so that the waste liquid enters the conduit 5 after being filtered by the filter plate 6.

[0031] In summary, compared with related technologies, by utilizing the dual protection of the inner tank 2 and the protective shell 3, combined with the seepage-proof layer 14 on the inner wall of the prefabricated shell 1, a three-level leak-proof system of "primary storage, secondary collection, and outer barrier" is formed, reducing the risk of leakage. Through the pretreatment filtration of the filter plate 6 inside the tank 4, combined with the stable installation of the filter plate 6 by the sliding plate, impurities in the waste liquid are intercepted, reducing the risk of corrosion of the inner tank 2 and blockage of the drainage mechanism. At the same time, the design of the inspection port and the sealing plate 16 facilitates the maintenance of the filter plate 6, ensuring the continuous effectiveness of the filtration function. The cooperation of the pump body 8, the connector 9 and the valve 11 in the drainage mechanism realizes the separate discharge of waste liquid from the inner tank 2 and leakage liquid from the protective shell 3. The extension of the outlet pipe 10 to the outside of the prefabricated shell 1 simplifies the docking operation and improves the convenience and safety of drainage.
