Description

Technical Field

[0001] This utility model relates to the field of waste organic solvent regeneration technology, specifically a waste organic solvent regeneration device. Background Technology

[0002] Waste solvents typically refer to solvents that have been used and lost their effectiveness, or solvents that did not react completely during chemical reactions. Their hazards include pollution to human health and the environment. The main methods for treating waste organic solvents include recycling and safe disposal. Recycling is achieved through methods such as distillation, activated carbon adsorption, and solvent extraction to recover and reuse resources.

[0003] Adsorption is a novel method for regenerating organic solvents, characterized by its simple operation, high efficiency, and good purification effect. When recycling waste organic solvents, the solvent is added to an adsorption column through an upper funnel. Activated carbon's strong adsorption capacity is utilized to remove impurities that can be adsorbed by the activated carbon. The adsorbed organic solvent then flows into a recovery bottle. However, waste organic solvents typically pass through the adsorption column quickly, resulting in a short residence time and insufficient contact with the activated carbon, leading to poor adsorption and incomplete impurity removal. Furthermore, while large particles are usually filtered out before adsorption, these filters are easily clogged by particulate matter, requiring regular disassembly and cleaning, which is inconvenient. Therefore, we propose a waste organic solvent regeneration device. Utility Model Content

[0004] The purpose of this invention is to provide a waste organic solvent regeneration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste organic solvent regeneration device, comprising a regeneration and recycling tank, a recycling port, an activated carbon adsorption column, a filter bucket, and partitions. The recycling port is located at the top of the regeneration and recycling tank, and a support is fixed above the regeneration and recycling tank. The activated carbon adsorption column is installed inside the support, and all partitions are installed inside the activated carbon adsorption column, with an opening at one end of each partition. The activated carbon adsorption column is filled with activated carbon particles. The filter bucket is installed above the activated carbon adsorption column, and a filter screen is installed at the top of the filter bucket. A horizontal arm is provided above the filter screen, and a scraper is fixed at the bottom of the horizontal arm, with the bottom of the scraper tightly fitted to the filter screen. A guide rail is installed on one side of the top of the support, and a lead screw is installed inside the guide rail. A motor is installed at one end of the guide rail, and the output end of the motor is fixedly connected to the lead screw.

[0006] Preferably, a drain pipe is installed on the outer wall of the bottom of the recycling bin, and a drain valve is installed inside the drain pipe.

[0007] Preferably, the activated carbon adsorption column is provided with a top cover at the top, and the top cover has an upper opening inside; the activated carbon adsorption column is provided with a bottom cover at the bottom, and the bottom cover has a lower opening inside.

[0008] Preferably, the inner side of the lower cover is provided with degreased cotton to prevent activated carbon particles from falling off.

[0009] Preferably, both the upper and lower covers are threadedly connected to the activated carbon adsorption column, and both the upper and lower covers are removable to facilitate the replacement of activated carbon particles.

[0010] Preferably, a slider is fitted on the outer wall of the lead screw, and the slider is threadedly connected to the lead screw, and one end of the slider extends to the outside of the guide rail and is fixedly connected to the cross arm.

[0011] Preferably, a sludge storage box is provided on both sides of the filter bucket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Waste organic solvent is poured into a filter hopper, where the filter screen performs preliminary filtration, removing large particulate impurities. The waste organic solvent then enters the activated carbon adsorption column through the top opening inside the top cover. Because the partition separates the internal space of the activated carbon adsorption column, the waste organic solvent can only flow from the opening, making the flow rate of the waste organic solvent slower and the flow path longer as it passes through the activated carbon adsorption column. This allows the waste organic solvent to fully contact the activated carbon particles, resulting in good adsorption and complete removal of impurities.

[0014] The motor is started to drive the lead screw to rotate, which causes the slider to move the horizontal arm along the guide rail. The scraper at the bottom of the horizontal arm scrapes across the surface of the filter screen, scraping particulate impurities on the surface of the filter screen into the sludge collection box. This facilitates automatic cleaning of the filter screen, prevents the filter screen from clogging, and eliminates the need to disassemble the filter screen, saving effort and making it convenient.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a waste organic solvent regeneration device, including a regeneration and recycling tank 1, a recycling port 2, an activated carbon adsorption column 4, a filter bucket 5, and a partition 7. The recycling port 2 is located at the top of the regeneration and recycling tank 1. A support 3 is fixed above the regeneration and recycling tank 1. The activated carbon adsorption column 4 is installed inside the support 3. All partitions 7 are installed inside the activated carbon adsorption column 4, and one end of the partition 7 is provided with a through-hole 701. The interior of the activated carbon adsorption column 4 is filled with activated carbon particles 8.

[0023] Specifically, the waste organic solvent enters the activated carbon adsorption column 4 through the upper opening 12 inside the upper cover 11. Since the partition 7 divides the internal space of the activated carbon adsorption column 4, the waste organic solvent can only flow from the opening 701, which makes the flow rate of the waste organic solvent slow down and the flow path longer when it passes through the activated carbon adsorption column 4. This allows the waste organic solvent to fully contact the activated carbon particles 8, resulting in good adsorption effect and complete removal of impurities.

[0024] The filter hopper 5 is installed above the activated carbon adsorption column 4, and a filter screen 6 is installed on the top of the filter hopper 5.

[0025] Specifically, the waste organic solvent is poured into the filter hopper 5, and the filter screen 6 performs preliminary filtration of the waste organic solvent, filtering out the large particulate impurities inside.

[0026] A horizontal arm 18 is provided above the filter screen 6, and a scraper 19 is fixed at the bottom end of the horizontal arm 18. The bottom end of the scraper 19 is in close contact with the filter screen 6. A guide rail 16 is installed on one side of the top of the bracket 3, and a lead screw 17 is installed inside the guide rail 16. A motor 21 is installed at one end inside the guide rail 16, and the output end of the motor 21 is fixedly connected to the lead screw 17.

[0027] Specifically, the motor 21 is started to drive the lead screw 17 to rotate, which causes the slider 20 to move the horizontal arm 18 along the guide rail 16. The scraper 19 at the bottom of the horizontal arm 18 scrapes across the surface of the filter screen 6, scraping particulate impurities on the surface of the filter screen 6 into the sludge collection box 22, thereby facilitating automatic cleaning of the filter screen 6, preventing the filter screen 6 from clogging, and eliminating the need to disassemble the filter screen 6, which is labor-saving and convenient.

[0028] A drain pipe 9 is installed on the outer wall of the bottom of the recycling bin 1, and a drain valve 10 is installed inside the drain pipe 9;

[0029] Specifically, the adsorbed organic solvent is discharged through the lower opening 14 inside the lower cover 13 and flows into the regeneration and recovery tank 1 through the recovery port 2. Then, the drain valve 10 is opened to allow the organic solvent to be discharged through the drain pipe 9.

[0030] The activated carbon adsorption column 4 is provided with an upper cover 11 at the top and an upper opening 12 inside the upper cover 11. The activated carbon adsorption column 4 is provided with a lower cover 13 at the bottom and a lower opening 14 inside the lower cover 13. Both the upper cover 11 and the lower cover 13 are removable, which makes it easy to replace the activated carbon particles 8.

[0031] The inner side of the lower cover 13 is provided with degreased cotton 15, which can prevent the activated carbon particles 8 from falling off.

[0032] Both the upper cover 11 and the lower cover 13 are threadedly connected to the activated carbon adsorption column 4;

[0033] A slider 20 is fitted on the outer wall of the lead screw 17, and the slider 20 is threadedly connected to the lead screw 17. One end of the slider 20 extends to the outside of the guide rail 16 and is fixedly connected to the cross arm 18.

[0034] Both sides of the filter hopper 5 are equipped with sludge collection boxes 22.

[0035] In this embodiment, the waste organic solvent is first poured into the filter hopper 5. The filter screen 6 performs preliminary filtration of the waste organic solvent, removing large particulate impurities. Then, the waste organic solvent enters the activated carbon adsorption column 4 through the upper opening 12 inside the upper cover 11. Because the partition 7 divides the internal space of the activated carbon adsorption column 4, the waste organic solvent can only flow from the opening 701, making the flow rate of the waste organic solvent slower and the flow path longer when passing through the activated carbon adsorption column 4. This allows the waste organic solvent to fully contact the activated carbon particles 8, resulting in good adsorption effect and complete removal of impurities. The degreasing cotton 15 prevents the activated carbon particles 8 from falling off. 11. The lower cover 13 is removable, which facilitates the replacement of activated carbon granules 8. Then, the adsorbed organic solvent is discharged through the lower opening 14 inside the lower cover 13 and flows into the regeneration and recovery tank 1 through the recovery port 2. Then, the drain valve 10 is opened to allow the organic solvent to be discharged through the drain pipe 9. The motor 21 is started to drive the lead screw 17 to rotate, so that the slider 20 drives the horizontal arm 18 to move along the guide rail 16. The scraper 19 at the bottom of the horizontal arm 18 scrapes across the surface of the filter screen 6, scraping the particulate impurities on the surface of the filter screen 6 into the sludge collection box 22, thereby facilitating automatic cleaning of the filter screen 6, preventing the filter screen 6 from clogging, without the need to disassemble the filter screen 6, saving effort and convenience.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
