On the other hand, the maintenance of the device is difficult. The key filtration components in the purification device are relatively fixedly installed, making the replacement and maintenance process very cumbersome for personnel. This not only increases the labor intensity of the personnel but also affects the production efficiency and reduces the practicality of the device. Therefore, we propose a device for purifying, recycling, and utilizing waste liquid of a distillation kettle to solve the above problems. Content of the Utility Model

Detailed implementation mode

[0023] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1-5 , a waste liquid purification and recycling device for a distillation kettle, including a distillation kettle body 1, an access pipe arranged at the top of the distillation kettle body 1, and a drain pipe arranged at one side of the bottom of the distillation kettle body 1. A filter box 4 is arranged on one side of the distillation kettle body 1, and the filter box 4 is in a funnel shape. A filling pipe 5 is connected to the top of the filter box 4, and one end of the filling pipe 5 is connected to a discharge pipe 3 connected to the inside of the drain pipe. A water pump 6 is fixedly installed on one side of the lower end of the filter box 4, and both ends of the water pump 6 are connected with transfer pipes 2. The two ends of the transfer pipes 2 far away from the water pump 6 are respectively connected to one side of the filter box 4 and one side of the access pipe. An installation frame 8 is arranged in the filter box 4, a filter screen 10 is arranged in the installation frame 8, and an activated carbon plate 11 is arranged below the filter screen 10. A sealing groove is arranged on one side of the filter box 4, and a sealing block 9 adapted to the sealing groove is fixedly installed on one side of the installation frame 8. A positioning component connected to the sealing block 9 is arranged on one side of the filter box 4. Support legs are fixedly connected to the four corners of the bottom of the filter box 4. Specifically, after the waste liquid is discharged from the distillation kettle body 1, it is introduced into the filling pipe 5 through the drain pipe and the discharge pipe 3 and then into the filter box 4. Subsequently, the waste liquid first removes large particles and impurities through the filter screen 10, and then flows through the activated carbon plate 11 for deep purification to remove harmful substances, pigments and odors. The purified liquid is pumped by the water pump 6 and flows back to the distillation kettle body 1 through the transfer pipe 2 and the access pipe to achieve recycling. At the same time, the device uses a positioning component to ensure the stable installation and convenient maintenance of the filtering component. Through the cooperation of the pull rod 14 and the sealing block 9, the quick loading and unloading of the installation frame 8 are realized, thereby significantly improving the resource utilization rate, reducing the production cost, reducing the labor intensity and improving the work efficiency.

[0025] Furthermore, the outside of the filter screen 10 is fixedly connected to the inside of the mounting frame 8, the outside of the activated carbon plate 11 is fixedly installed to the inside of the mounting frame 8, a slot is provided on one side of the sealing block 9, and a socket adapted to the slot is provided on one side of the filter box 4. Specifically, through the arrangement of the filter screen 10, the activated carbon plate 11 and the mounting frame 8, the filter screen 10 is installed in the mounting frame 8 and is at a large distance from the top of the mounting frame 8, so that larger suspended particles and organic matter and other debris in the waste liquid can be retained in the mounting frame 8, while smaller suspended impurities can be adsorbed and intercepted by the activated carbon plate 11, thereby being removed through physical filtration, making the waste liquid clear.

[0026] Furthermore, a clamping plate 7 is fixedly attached to each inner wall of the filter box 4. The adjacent side walls of the two clamping plates 7 are each provided with slots that mate with the side walls of the mounting frame 8. Specifically, the arrangement of the clamping plates 7 and the slots provided by the clamping plates 7 ensure that the adjacent side walls of the two clamping plates 7 are carefully provided with slots that mate with the side walls of the mounting frame 8. This ensures that the mounting frame 8 can be smoothly and accurately inserted and securely positioned. During installation, the mounting frame 8 is carefully placed within the filter box 4 and gradually approaches the slots, guided by the clamping plates 7. As the mounting frame 8 is pushed further in, its side walls gradually come into contact with the edges of the slots, creating a slight squeeze until it is fully inserted. Once the mounting frame 8 is fully inserted into the slots, the clamping plates 7 use the slots to fully constrain the side walls of the mounting frame 8. This restraining action not only prevents horizontal drift and shaking of the mounting frame 8 during use, but also ensures its vertical stability. Therefore, even during wastewater treatment processes at high flow rates or high pressures, mounting frame 8 maintains its original position and orientation, ensuring continuous and efficient wastewater treatment and facilitating easier maintenance. When the filter screen 10 and activated carbon plate 11 need to be replaced, simply disconnecting the filter box 4 from the sealing block 9 allows for easy removal of mounting frame 8 and its internal components, saving maintenance time and labor costs.

[0027] Further, the positioning component includes a connecting plate 12 provided on one side of the filter box 4. The connecting plate 12 is U-shaped, and both side walls at the two ends of the connecting plate 12 are fixedly connected to the adjacent outer side walls of the filter box 4. A pull rod 14 is provided inside the connecting plate 12. One end of the pull rod 14 is inserted into the slot through the jack, and the other end of the pull rod 14 penetrates through the side wall of the connecting plate 12 and is fixedly connected with a pull block. Specifically, the connecting plate 12 is designed as a U-shaped structure, and the two side walls at the two ends of the U-shape are firmly fixedly connected to the adjacent outer side walls of the filter box 4, forming a stable support frame. This frame provides an installation basis for the pull rod 14 and ensures the stability and directionality of the pull rod 14 during movement. When it is necessary to load or unload the installation frame 8 or the sealing block 9, the operator can hold the pull block and pull the pull rod 14 outwards. As the pull rod 14 is gradually pulled out of the slot, the locking state of the installation frame 8 or the sealing block 9 will be released, and at this time, it can be easily taken out of or put into the filter box 4, improving the operation convenience.

[0028] Further, the positioning component further includes a spring 13 provided on one side of the connecting plate 12. The inside of the spring 13 is sleeved on the outside of the pull rod 14, and both ends of the spring 13 are fixedly connected to the pull block and the adjacent side wall of the connecting plate 12 respectively. Specifically, through the setting of the spring 13, when the operator holds the pull block and pulls the pull rod 14 to move so that one end of it is separated from the slot to release the positioning of the sealing block 9, at this time, the pull block stretches the spring 13, and after the pull rod 14 moves, the sealing block 9 and the installation frame 8 can be pulled out to maintain the filter screen 10 and the activated carbon plate 11. During installation, by aligning the two sides of the installation frame 8 with the slots and sliding them in, the pull block can be released, and the spring 13 elastically returns to drive the pull block to drive the pull rod 14 to return to its position, so that one end of it is inserted into the slot to position the sealing block 9, thereby firmly installing the installation frame 8 in the filter box 4, improving the operation efficiency and convenience.

[0029] Further, a handle is fixedly connected to the outer wall of the sealing block 9 away from the installation frame 8, and the handle is U-shaped. Specifically, through the setting of the handle, it is convenient for the operator to hold the handle and pull out the sealing block 9 and the installation frame 8 in the filter box 4, facilitating the operation to maintain or replace the filter screen 10 and the activated carbon plate 11.

[0030] In summary: The filter screen 10 is installed at a relatively large distance from the top of the installation frame 8. The ingenuity of this design lies in that it can effectively intercept large suspended particles, organic substances and other debris in the waste liquid. When the waste liquid flows through the filter screen 10, these larger impurities will be blocked on the filter screen 10, thus preventing them from entering the subsequent treatment process, ensuring the normal operation of the subsequent treatment equipment and extending its service life. After the filter screen 10 preliminarily filters out large particle impurities, the waste liquid continues to flow through the activated carbon plate 11. The activated carbon plate 11 uses its porous structure and large specific surface area to adsorb and intercept smaller suspended impurities in the waste liquid. These impurities may include tiny suspended particles, dissolved organic substances, etc. When they pass through the activated carbon plate 11, they will be adsorbed on the pore surface, thus realizing the separation from the waste liquid. The waste liquid recovery device for the distillation kettle can effectively remove suspended particles and organic substances and other impurities in the waste liquid, making the waste liquid clear and meeting the requirements for subsequent treatment and recycling.

[0031] When the operator holds the pulling block and pulls the pull rod 14 outwards, one end of the pull rod 14 will gradually move out of the slot, and at this time, the spring 13 will be stretched. As the pull rod 14 continues to move, the stretching amount of the spring 13 gradually increases until the pull rod 14 completely moves out of the slot and releases the positioning of the sealing block 9. During this process, the spring 13 stores elastic potential energy. When installing or repositioning the installation frame 8, the operator only needs to align the two sides of the installation frame 8 with the card slots and gently slide it in. Once the installation frame 8 is in place, the operator can release the pulling block. At this time, the spring 13 will automatically perform elastic recovery using the elastic potential energy it stores, pushing the pulling block and the pull rod 14 towards the slot direction. As the pull rod 14 gradually returns to its original position, one end of it will re-insert into the slot, thus realizing the repositioning of the sealing block 9. This automatic return design greatly simplifies the operation process, improves work efficiency, not only enhances the operation convenience and stability of the waste liquid treatment system, but also reduces the labor intensity and safety risks, and extends the service life of the components.
