Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a hazardous waste organic solvent feeding device, including a material pipe 1, a material cylinder 2, a feeding pump 3, a stirring motor 4, a stirring rod 5, and a spray pipe 6. A support frame 7 is fixedly connected to the bottom of the material cylinder 2, and the feeding pump 3 is fixedly connected to the bottom of the material cylinder 2. The stirring rod 5 is rotatably connected inside the material cylinder 2. The stirring motor 4 is fixedly connected to the top of the material cylinder 2, and the output end of the stirring motor 4 is fixedly connected to the top of the stirring rod 5. The top of the material cylinder 2 is also provided with a feeding port 8. The feeding pump 3 is fixedly connected to the bottom of the material cylinder 2, and the feeding port 8 of the feeding pump 3 is connected to the material cylinder 2. The material pipe 1 is located on the side wall of the material cylinder 2 and is connected to the output end of the feeding pump 3. The end of the material pipe 1 is fixedly connected to the spray pipe 6.

[0023] In a further improvement, the nozzles 6 are arranged in a ring shape, and a number of nozzles 9 are fixedly connected to the inner wall of the nozzles 6. By fixing a number of nozzles 9 to the inner wall of the nozzles 6, it is convenient to spray the organic solvent evenly into the incinerator, thereby improving the efficiency of organic solvent incineration.

[0024] In a further improvement, a fixing clip 10 is fixedly connected to the outer wall of the nozzle 6, and a connector 11 communicating with the nozzle 6 is also provided on the outer wall of the nozzle 6. The connector 11 is inserted into the material pipe 1. By fixing the connector 11 to the outer wall of the nozzle 6, it is convenient to connect the nozzle 6 and the material pipe 1, so as to facilitate the pumping of organic solvent into the nozzle 6.

[0025] In a further improvement, an inner support frame 12 is provided between the stirring rod 5 and the inner wall of the barrel 2. The stirring rod 5 passes through the inner support frame 12 and is rotatably connected to the inner support frame 12. A blade 13 is fixedly connected to the surface of the stirring rod 5. By providing an inner support frame 12 between the stirring rod 5 and the barrel 2, the stability of the connection between the stirring rod 5 and the barrel 2 is improved. In conjunction with the blade 13 on the side wall surface, it is convenient to mix and dilute the organic solvent of the waste with water, which facilitates incineration.

[0026] Further improvements include a universal wheel 14 fixedly connected to the bottom of the support frame 7, and a shock-absorbing rubber pad 15 fixedly connected to the connection between the support frame 7 and the material cylinder 2. By fixing the universal wheel 14 to the bottom of the support frame 7, the feeding device can be moved as a whole, making it easy to use with different incinerators. By providing the shock-absorbing rubber pad 15 at the connection between the support frame 7 and the material cylinder 2, the vibration noise during the stirring process is reduced.

[0027] Specifically, the feed pump 3 is composed of a feed motor 16, a pump body 17, a flow meter 18, and a controller 19. The feed motor 16 and the pump body 17 are fixedly connected to the surface of the support frame 7. The output end of the feed motor 16 is connected to the pump body 17. The flow meter 18 is fixedly connected to the output end of the pump body 17. The controller 19 is connected to both the feed motor 16 and the flow meter 18. By providing a flow meter 18 at the output end of the pump body 17, it is convenient to monitor the feed rate of the organic solvent in real time. At the same time, it is convenient to coordinate with the control to perform closed-loop control of the feed motor 16, and to adjust the feed rate according to the combustion efficiency of different incinerators.

[0028] In use, the feeding device is moved to the incinerator, the spray pipe 6 is fixedly connected to the inner wall of the incinerator and connected to the feed pipe 1, and the hazardous waste organic solvent and water are added to the feed cylinder 2 through the feed inlet 8 in a certain proportion. The stirring motor 4 drives the stirring rod 5 to mix and stir the hazardous waste organic solvent and water. After stirring and dilution, the hazardous waste organic solvent is pumped into the feed pipe 1 by the feed pump 3 and sprayed into the incinerator through the nozzle 9 on the inner wall of the spray pipe 6, which improves the efficiency of incineration of hazardous waste organic solvent. The flow meter 18 is used to monitor the feeding speed and feeding amount, and the feeding amount of the feed pump 3 can be adjusted in real time according to the incineration status of the incinerator. This avoids that excessive feeding may cause the temperature inside the incinerator to be too high, increasing pollutant emissions, while insufficient feeding may cause the temperature inside the furnace to be too low, resulting in incomplete combustion.

[0029] The present invention addresses the problem that existing incinerators for treating hazardous waste organic solvents are typically equipped with fixed feeding devices, which can only be used in a single incinerator. This limits the versatility of the incinerator and reduces its utilization efficiency. The present invention utilizes a feeding device consisting of a feed pipe 1, a feed cylinder 2, a feed pump 3, a stirring motor 4, a stirring rod 5, and a spray pipe 6 to facilitate the spraying of organic solvents into the incinerator in a mist form. This increases the heating area of ​​the organic solvents, improves the combustion efficiency, and the independent feeding device allows for easy use and adjustment with different incinerators, thus improving versatility.
