Description

Technical Field

[0001] This invention relates to the field of chemical waste treatment technology, specifically to a safe chemical waste treatment device and its treatment process. Background Technology

[0002] In industrial sectors such as chemical engineering, pharmaceuticals, and environmental governance, the harmless treatment of chemical waste is a crucial link in ensuring production safety and the ecological environment. Such treatment devices are widely used in industrial wastewater treatment sections and environmental sewage treatment plants to treat chemical waste containing suspended particles and chemical pollutants through reagent reactions and solid-liquid separation, achieving compliant discharge or resource recovery of wastewater, which is of great significance for promoting green and sustainable industrial development.

[0003] The chemical waste liquid treatment device disclosed in Chinese patent document CN223547866U completes the treatment through the cooperation of a reaction tank, an independent stirring mechanism, and a filter assembly: after the waste liquid and reagent are introduced into the reaction tank, the stirring mechanism is started to stir the mixture, and after the reaction is completed, the solid and liquid are separated by the filter assembly; however, the stirring mechanism of this device only has a single mixing function and has no linkage structure with the separation assembly. In practical applications, it is easy to have reaction dead zones where the waste liquid and reagent are not mixed evenly, which affects the uniformity of the reaction process.

[0004] The device disclosed in Chinese patent document CN220877933U is equipped with a material tank, a reaction vessel, and a separation mechanism. After the reagents are initially mixed in the material tank, they are sent to the reaction vessel for reaction, and then the products are separated by the separation mechanism. However, the device adopts a fixed filtration structure, which cannot actively collect the solid waste after the reaction, and it is also difficult to compress the waste. This results in problems such as incomplete solid-liquid separation and inconvenient waste collection.

[0005] To address the shortcomings of existing technologies, this application achieves thorough mixing and reaction of waste liquid and reagents, while also efficiently collecting the solid waste after the reaction and reducing its volume through compression with a solid ring. Simultaneously, a filter column assists in the pure discharge of the waste liquid, significantly improving the thoroughness of solid-liquid separation and the convenience of collecting the treated material. This effectively compensates for the technical defects of existing patented devices, such as poor connection between mixing and separation processes and low processing efficiency, thus meeting the actual needs of efficient industrial waste liquid treatment. Summary of the Invention

[0006] The purpose of this invention is to provide a safe treatment device for chemical waste liquid and its treatment process.

[0007] The objective of this invention is achieved through the following technical solution: a safe treatment device for chemical waste liquid and its treatment process, comprising a base, a reaction tank at the top of the base, a tank cover at the top of the reaction tank, a stirring assembly on the tank cover, a partition ring inside the reaction tank, multiple U-shaped connecting plates at the top of the partition ring, two sliding rods slidably connected inside the partition ring, a conical block at the top of the sliding rod, a transmission mechanism fixedly connected to the bottom of the sliding rod, a connecting long rod rotatably connected inside the reaction tank, multiple connecting short plates fixedly connected to the outside of the connecting long rod, a limit post fixedly connected to every two connecting short plates, a semi-elliptical plate slidably connected to the outside of the limit post, a connecting rod rotatably connected to the outside of the semi-elliptical plate, and two annular filter tanks, two solid annular rings, and a filter column respectively at the top of the multiple connecting rods.

[0008] As a further description of the above technical solution: The stirring assembly includes a motor, a rotating rod is fixedly connected to the drive end of the motor, a plurality of stirring plates are provided on the outside of the rotating rod, and a connecting inclined plate is fixedly connected to the outside of the rotating rod. As a further description of the above technical solution: The transmission mechanism includes two square hollow plates, each with a toothed rack. A hollow column one is fixedly connected to the bottom of the square hollow plate, and a hollow column two is slidably connected to the outside of the hollow column one. Springs are installed inside the hollow column one and the hollow column two, with one end of the spring fixedly connected to the inside of the hollow column one and the other end of the spring fixedly connected to the inside of the hollow column two. Two gears are fixedly connected to the outside of the connecting rod, and the square hollow plates are meshed with the gears. As a further description of the above technical solution: The top of the base is provided with a storage box, and two stirring blades are rotatably connected inside the storage box. A V-shaped plate is provided inside the storage box. As a further description of the above technical solution: The discharge end of the storage tank is equipped with a water pump one, the discharge end of the reaction tank is fixedly connected to a water pump two, the output end of the water pump two is fixedly connected to a receiving tank, and the top of the tank cover is equipped with a gas filter box. As a further description of the above technical solution: An inclined plate is provided at the bottom end of the connecting inclined plate, and the inclined surface of the inclined plate is in contact with the outside of the conical block; As a further description of the above technical solution: The two annular filter canisters are slidably connected to the outside of the partition ring, and the filter column is slidably connected to the outside of the partition ring. As a further description of the above technical solution: The solid circular ring is slidably connected to the inside of the circular ring filter tank, and the connecting short plate is slidably connected to the outside of the semi-elliptical plate. As a further description of the above technical solution: A safe treatment process for chemical waste liquid, wherein the method employs a safe treatment device for chemical waste liquid, and the method is as follows: S1. Put the chemical waste liquid treatment agent into the storage tank and start the stirring blades inside the storage tank to mix the agent; after the mixing is completed, the mixed agent is transported to the reaction tank by water pump 1, and at the same time the chemical waste liquid to be treated is introduced into the reaction tank. S2. Start the stirring assembly on the tank cover. The motor drives the rotating rod to stir the waste liquid and the agent with the stirring plate. At the same time, the connecting inclined plate outside the rotating rod rotates with it. The inclined surface of the connecting inclined plate contacts the conical block, which drives the sliding rod and the square hollow plate to move down synchronously. S3. The toothed rack on the square hollow plate meshes with the gear on the outside of the connecting rod, causing the connecting rod to rotate. The connecting short plates of different lengths and distributions on the connecting rod rotate accordingly. Through the transmission of the limiting column, the semi-elliptical plate, and the connecting rod, the circular filter tank, the solid circular ring, and the filter column move up and down in a corrugated manner. The solid waste precipitated after the waste liquid reaction enters the circular filter tank. When the circular filter tank moves down to the partition ring area, the solid ring rises synchronously, squeezing the solid waste inside the circular filter tank. S4. The wastewater after the reaction is discharged through the filter column. The filter column does not collect solid waste. The second water pump is started to transport the liquid after the filter column to the collection tank, and the gas filter box collects and filters the gas generated during the wastewater treatment.

[0009] Compared with the prior art, the advantages of the present invention are as follows: 1. The motor of the stirring assembly drives the rotating rod, which in turn drives the stirring plate and the connecting inclined plate. This causes the square hollow plate to drive the gear, which in turn drives the connecting long rod. The connecting long rod drives the connecting short plates of varying lengths, which in turn drive the semi-elliptical plate, the connecting rod, and the circular filter tank and solid circular ring. This achieves the beneficial effect of efficiently collecting solid waste after the waste liquid reaction and reducing the volume of waste through compression by the solid circular ring. At the same time, the filter column assists in the pure discharge of waste liquid, improving the thoroughness of solid-liquid separation and the convenience of collecting the processed materials.

[0010] 2. The motor of the stirring assembly drives the rotating rod, which in turn drives the stirring plate. The stirring plate continuously stirs the waste liquid and the reagent, achieving the beneficial effect of full contact between the chemical waste liquid and the treatment agent, and a more uniform and efficient reaction process. This effectively avoids reaction dead zones caused by insufficient local mixing and improves the mixing quality and reaction efficiency of the waste liquid in the early stage of treatment.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1 and 9The diagram shown is a schematic representation of an embodiment of a safe chemical waste liquid treatment device provided by the present invention. It includes a base 1, with a reaction tank 2 mounted on the top of the base 1. The reaction tank 2 provides a closed environment for the chemical waste liquid and treatment agents to react chemically, and also supports the installation and operation of subsequent solid-liquid separation components.

The rotating rod 5 supports the stirring-related functional components, providing a mounting carrier for these components, and also serves as the basic component for power transmission. Multiple stirring plates 6 are mounted outside the rotating rod 5. The stirring plates 6 are used to agitate the chemical waste liquid and treatment agents within the reaction tank 2, increasing the volume of the waste liquid. The contact area with the reagent promotes the uniform chemical reaction between the two. A connecting inclined plate 7 is fixedly connected to the outside of the rotating rod 5. The connecting inclined plate 7 is used to form a contact fit with the corresponding component, providing the trigger condition for the action of subsequent related structures and assisting in the connection of different processing links. An inclined plate is provided at the bottom end of the connecting inclined plate 7. The inclined surface of the inclined plate is in contact with the outside of the conical block 11. A partition ring 8 is provided inside the reaction vessel 2. Multiple U-shaped connecting plates 9 are provided at the top of the partition ring 8. Two sliding rods 10 are slidably connected inside the partition ring 8. The sliding rods 10 are used to reciprocate in the corresponding area, providing the basis for position adjustment for the action of subsequent related functional structures. A conical block 11 is provided at the top of the sliding rod 10. The conical block 11 is used to form a contact point with the corresponding component, providing the contact basis for triggering the action of related structures.

[0014] A transmission mechanism is fixedly connected to the bottom end of the sliding rod 10. The transmission mechanism includes two square hollow plates 12. The square hollow plates 12 are used to support specific functional components, providing a carrier space for the installation and operation of these components. A toothed rack 13 is provided on the square hollow plates 12, which is used to mesh with corresponding components to achieve connection during power transmission and ensure the effectiveness of power transmission. A hollow column 14 is fixedly connected to the bottom end of the square hollow plates 12. The hollow column 14 is used to move inside the corresponding structure, assisting in the adjustment of the structure's position and providing a basic component for the structure's repositioning. A hollow column 2 15 is slidably connected to the outside of the hollow column 14. The hollow column 2 15 is used to support the... To provide space for the structure's movement and to help ensure stability during the movement, hollow columns 14 and 15 are equipped with springs 16. Springs 16 provide elastic force during the movement of the structure, enabling elastic reset and supporting the reciprocating motion. One end of spring 16 is fixedly connected to the inside of hollow column 14, and the other end is fixedly connected to the inside of hollow column 15. Two gears 18 are fixedly connected to the outside of the connecting rod 17. Gears 18 are used to mesh with corresponding components to realize the conversion of power transmission direction and assist in the transmission of power between different structures. The square hollow plate 12 is meshed with the gears 18.

[0015] The reaction vessel 2 is internally connected to a connecting rod 17, which supports multiple functional components and provides a centralized mounting platform for these components, thus aiding in the synchronous operation of multiple components. Multiple connecting short plates 19 are fixedly connected to the outside of the connecting rod 17. These connecting short plates 19 support corresponding limiting components, providing installation positions for these components and aiding in the transmission of motion. A solid ring 23 is externally slidably connected to the inside of a circular filter tank 24. The solid ring 23 enters the internal area of ​​the circular filter tank 24 to compress the solid waste collected inside, reducing its volume and improving storage convenience. The connecting short plates 19 are externally slidably connected to the outside of a semi-elliptical plate 21. The semi-elliptical plate 21 deflects during operation, aiding in the conversion of power transmission direction and ensuring the linkage of subsequent structural actions. Limiting posts 20 are fixedly connected to every two connecting short plates 19. These limiting posts 20 move within the sliding area of ​​the corresponding structure, restricting the movement of that structure. The movement trajectory ensures the orderly execution of the action. The external sliding connection of the limiting column 20 is a semi-elliptical plate 21. The semi-elliptical plate 21 is used to deflect at an angle during the action, which helps to realize the conversion of the power transmission direction and ensures the linkage basis of subsequent structural actions. The external rotating connection of the semi-elliptical plate 21 is a connecting rod 22. The connecting rod 22 is used to connect different functional components, providing a connection carrier for the action transmission between components and assisting in the coordinated action of multiple components. The top of the multiple connecting rods 22 is respectively provided with two annular filter tanks 24, two solid rings 23 and filter columns 25. The annular filter tanks 24 are used to collect solid precipitates generated after the chemical waste liquid reaction, providing a dedicated carrier space for the centralized collection of solid waste. The filter columns 25 are used to filter the wastewater after the reaction, allowing only the treated liquid to pass through and not collecting solid waste, ensuring the purity of the discharged liquid. The external sliding connection of the two annular filter tanks 24 is to the outside of the partition ring 8, and the external sliding connection of the filter column 25 is to the outside of the partition ring 8.

[0016] A storage bin 26 is installed at the top of the base 1. The storage bin 26 is used to hold the chemical waste liquid treatment agents to be mixed, providing an independent space for the centralized storage of multiple agents. Two stirring blades 27 are rotatably connected inside the storage bin 26. The stirring blades 27 are used to agitate the multiple treatment agents added into the storage bin 26, promoting full contact between different types of agents and achieving uniform mixing. A V-shaped plate 28 is installed inside the storage bin 26 to assist the agents in converging towards the bottom area of ​​the bin, reducing agent residue in the corners and improving the converging effect during the mixing process. A water pump 29 is installed at the outlet of the storage bin 26. The water pump 29 is used to pump the uniformly mixed treatment agents from the storage bin 26. The reagent is transferred to the inside of the reaction tank 2, completing the transfer operation of the reagent from the storage unit to the reaction unit. The discharge end of the reaction tank 2 is fixedly connected to the second water pump 30. The second water pump 30 is used to transfer the liquid after being treated by the filter column 25 in the reaction tank 2 to the receiving tank 31, completing the transfer of the treated liquid from the reaction unit to the storage unit. The output end of the second water pump 30 is fixedly connected to the receiving tank 31. The receiving tank 31 is used to store the treated liquid that meets the standards, providing an independent space carrier for the centralized storage of the treated liquid. The top of the tank cover 3 is equipped with a gas filter box 32. The gas filter box 32 is used to filter the volatile gases generated during the treatment of chemical waste liquid, remove harmful components from the gas, and ensure the safety and compliance of the emitted gas.

[0017] like Figure 10 The diagram shown is a flow chart of a safe chemical waste liquid treatment process provided by the present invention. The method employs a safe chemical waste liquid treatment device, and the method is described below: S1. Put the chemical waste liquid treatment agent into the storage tank 26, and start the stirring blade 27 inside the storage tank 26 to mix the agent; after the mixing is completed, the mixed agent is transported to the reaction tank 2 by the water pump 29, and at the same time, the chemical waste liquid to be treated is introduced into the reaction tank 2. S2. Start the stirring assembly on the tank cover 3. The motor 4 drives the rotating rod 5 to stir the stirring plate 6 and the waste liquid and the agent. At the same time, the connecting inclined plate 7 outside the rotating rod 5 rotates with it. The inclined surface of the connecting inclined plate 7 contacts the conical block 11, which drives the sliding rod 10 and the square hollow plate 12 to move down synchronously. S3, the toothed rack 13 on the square hollow plate 12 meshes with the gear 18 on the outside of the connecting rod 17, driving the connecting rod 17 to rotate; the connecting short plates 19 of different lengths and distributions on the connecting rod 17 rotate accordingly, and through the transmission of the limiting column 20, the semi-elliptical plate 21, and the connecting rod 22, the annular filter tank 24, the solid ring 23, and the filter column 25 move up and down in a corrugated shape; the solid waste precipitated after the waste liquid reaction enters the annular filter tank 24, and when the annular filter tank 24 moves down to the area of ​​the partition ring 8, the solid ring 23 rises synchronously, squeezing the solid waste in the annular filter tank 24; S4. The wastewater after the reaction is discharged through the filter column 25. The filter column 25 does not collect solid waste. The water pump 30 is started to transport the liquid after the filter column 25 to the receiving tank 31. The gas filter box 32 collects and filters the gas generated during the wastewater treatment.

[0018] Working Principle: The working process of this chemical waste liquid safety treatment device mainly covers reagent preparation, stirring reaction and transmission triggering, separation component operation, solid-liquid separation and discharge, and gas treatment. The specific process is as follows: Reagent preparation: First, the treatment reagent suitable for the chemical waste liquid to be treated is put into the storage tank 26. Then, the stirring blade 27 in the storage tank 26 is started. The stirring blade 27 rotates to mix and stir the added reagent. The V-shaped plate 28 in the storage tank 26 assists in the collection of reagents in the tank, ensuring that different reagents are fully contacted and mixed. After the reagents are stirred to a uniform state, the water pump 29 at the discharge end of the storage tank 26 is started. The water pump 29 transports the mixed reagents into the reaction tank 2. At the same time, the chemical waste liquid to be treated is introduced into the tank through the inlet of the reaction tank 2, so that the mixed reagents and chemical waste liquid are initially combined in the reaction tank 2.

[0019] Stirring reaction and transmission triggering process: After feeding is completed, the stirring assembly on the tank cover 3 is started. The motor 4 in the assembly runs, and its drive end drives the rotating rod 5 to rotate inside the reaction tank 2. Multiple stirring plates 6 outside the rotating rod 5 rotate synchronously with the rod. The stirring plates 6 continuously stir the waste liquid and reagents in the tank, promoting the chemical reaction between the two. At the same time, the connecting inclined plate 7 fixed outside the rotating rod 5 rotates together with the rod. The inclined plate at the bottom of the connecting inclined plate 7 contacts the conical block 11 at the top of the sliding rod 10. As the rotating rod 5 continues to rotate, the inclined surface of the connecting inclined plate 7 continues to act on the conical block 11, causing the sliding rod 10 to slide downward along the interior of the partition ring 8. The downward movement of the sliding rod 10 synchronously drives the square hollow plate 12 at its bottom to move downward. At this time, the hollow column 14 at the bottom of the square hollow plate 12 slides along the interior of the hollow column 2 15. The springs 16 inside the hollow column 14 and the hollow column 2 15 are gradually compressed.

[0020] Separation component operation: During the downward movement of the square hollow plate 12, the toothed rack 13 on its surface meshes with the gear 18 on the outside of the connecting rod 17. The movement of the toothed rack 13 drives the gear 18 to rotate, which in turn drives the connecting rod 17 to rotate inside the reaction vessel 2. When the connecting rod 17 rotates, multiple connecting short plates 19 fixed to its outside rotate synchronously. These connecting short plates 19 are of different lengths and have different distribution positions. During the rotation, the connecting short plates 19 drive the end limiting posts 20 to move. The limiting posts 20 slide within the sliding area of ​​the semi-elliptical plate 21. At the same time, the semi-elliptical plate 21 deflects at an angle as the limiting posts 20 move. The change in the angle of the semi-elliptical plate 21 drives the external rotating connecting... When the connecting rod 22 moves, since the top of the connecting rod 22 is connected to two annular filter tanks 24, two solid rings 23 and filter column 25 respectively, the annular filter tanks 24, solid rings 23 and filter column 25 move up and down in a corrugated state under the transmission of the connecting rod 22. At this time, the waste liquid in the reaction tank 2 has produced solid precipitate waste after the previous stirring reaction. With the assistance of the waste liquid flow and the action of the separation component, the solid waste gradually enters the interior of the annular filter tank 24. When the annular filter tank 24 moves down to the area of ​​the partition ring 8 with the corrugated movement, the corresponding solid ring 23 moves up synchronously. The outside of the solid ring 23 slides into the interior of the annular filter tank 24 to squeeze the solid waste collected in the tank.

[0021] Solid-liquid separation, discharge, and gas treatment: Wastewater that has undergone chemical reaction and preliminary separation in reaction tank 2 flows to filter column 25 under its own gravity and with the assistance of the separation components. Filter column 25 only filters and discharges the wastewater and does not collect solid waste. The wastewater treated by filter column 25 is collected at the discharge end area of ​​reaction tank 2. Then, water pump 30 at the discharge end of reaction tank 2 is started. Water pump 30 pumps the treated wastewater out of the tank and transports it to the receiving tank 31 for storage. At the same time, the volatile gases generated in reaction tank 2 during the entire wastewater treatment process enter the gas filter box 32 through the ventilation end at the top of the tank cover 3. The gas filter box 32 filters these gases to remove harmful components and ensure that the final emitted gas meets safety standards.

S2. Start the stirring assembly on the tank cover (3). The motor (4) drives the rotating rod (5) to drive the stirring plate (6) to stir the waste liquid and the medicine. At the same time, the connecting inclined plate (7) outside the rotating rod (5) rotates with it. The inclined surface of the connecting inclined plate (7) contacts the conical block (11), which drives the sliding rod (10) and the square hollow plate (12) to move down synchronously. S3, the toothed rack (13) on the square hollow plate (12) meshes with the gear (18) on the outside of the connecting rod (17), driving the connecting rod (17) to rotate; the connecting short plates (19) of different lengths and distributions on the connecting rod (17) rotate accordingly, and through the transmission of the limiting column (20), the semi-elliptical plate (21), and the connecting rod (22), the circular filter tank (24), the solid circular ring (23), and the filter column (25) move up and down in a corrugated manner; the solid waste precipitated after the waste liquid reaction enters the circular filter tank (24), and when the circular filter tank (24) moves down to the area of ​​the partition ring (8), the solid circular ring (23) rises synchronously, squeezing the solid waste in the circular filter tank (24); S4. The wastewater after the reaction is discharged through the filter column (25). The filter column (25) does not collect solid waste. The second water pump (30) is started to transport the liquid after the filter column (25) to the receiving tank (31). The gas filter box (32) collects and filters the gas generated during the wastewater treatment.
