[0037] The utility model is provided with a self-cleaning and drying mechanism 1. The original dichloran waste residue is first added into the self-cleaning and drying mechanism 1. Through vacuum distillation, the dry residue and solvent vapor in the original dichloran waste residue are separated. Then, through a primary condensation mechanism 2 and a secondary condensation mechanism 4, the solvent vapor is condensed into a solvent liquid as much as possible, realizing the recovery of the solvent in the original dichloran waste residue, solving the problem that the solvent in the original dichloran waste residue cannot be recycled in the prior art, avoiding waste of resources, and avoiding the pollution of soil and water resources caused by directly burying the waste residue.

[0038] As Figure 4 shown, in this embodiment, the self-cleaning and drying mechanism 1 includes a drying body 11, a drying chamber arranged in the drying body 11, a stirring motor installed on the drying body 11, a stirring shaft coaxially arranged with the stirring motor and extending into the drying chamber, a vacuum pump installed on the drying body 11 for evacuating the drying chamber, at least two drying inlets arranged on the drying body 11 and communicated with the drying chamber, a solid outlet 13 opened below the drying body 11, and at least one steam outlet 14 opened above the drying body 11; wherein, the drying inlets include a first drying inlet 121 for adding dichloran waste residue and a second drying inlet 122 for communicating with external low-pressure steam; the inlet of the primary condensation mechanism 2 is connected to the steam outlet 14 through a pipeline; the dry residue discharge system 6 is connected to the solid outlet 13 through a pipeline.

[0039] During use, first, the dichloran waste residue is added into the drying chamber through the first drying inlet 121. The steam system is started, and hot steam is injected into the drying chamber through the second drying inlet 122. At the same time, the stirring motor is started, and the waste residue is heated through the stirring shaft and the matching jacket. The vacuum pump is started to form a negative pressure environment in the dryer, and vacuum distillation is carried out on the waste residue. The remaining solvent in the waste residue evaporates under the conditions of negative pressure and heating, generating solvent vapor. The solvent vapor enters the primary condensation mechanism 2 and the secondary condensation mechanism 4 for condensation into a liquid solvent.

[0040] Specifically, as Figure 1 shown, in this embodiment, the primary condensation mechanism 2 includes a spiral plate condenser 21, a first circulating return water inlet 22 and a first circulating return water outlet 23 that are condensated in cooperation with the spiral plate condenser 21. Ball valves for controlling the on-off of the respective circuits are provided on the circulating water return circuits connected to the first circulating return water inlet 22 and the first circulating return water outlet 23. As Figure 2As shown in the figure, the secondary condensation mechanism 4 of this embodiment includes a vacuum condensate hydrazine 41, a screw vacuum unit 42 that is in gas circuit communication with the vacuum condensate hydrazine 41 and is used to evacuate the vacuum condensate hydrazine 41, and a second circulating return water inlet 43 and a second circulating return water outlet 44 that are used for condensation cooperation with the vacuum condensate hydrazine 41; on the circulating water return circuit connected to the second circulating return water inlet 43 and the second circulating return water outlet 44, ball valves for controlling the on / off of the respective circuits are provided.

[0041] In this embodiment, the self-cleaning and drying mechanism 1 includes three steam output ports 14; the three steam output ports 14 are evenly distributed above the drying body 11. The three steam output ports 14 are all in communication with the input port of the primary condensation mechanism 2. The setting of the three steam output ports 14 can transport the solvent vapor in the drying chamber to the primary condensation mechanism 2 as much as possible. The secondary condensation mechanism 4 further condenses the solvent vapor that has not been completely condensed in the primary condensation mechanism 2, so as to recover the solvent vapor into a liquid solvent as much as possible.

[0042] Refer to Figure 5 , the solvent receiving tank 3 in this embodiment includes a receiving tank body 31, and a first upper output port 32, a second upper output port 33, a lower output port 34, and a receiving tank input port 35 are provided on the receiving tank body 31. The receiving tank input port 35 is in communication with the output port of the primary condensation mechanism 2; the first upper output port 32 is in gas circuit communication with the secondary condensation mechanism 4; the lower output port 34 is in liquid circuit communication with the solvent storage tank 5.

[0043] It should be further noted that the dithianon waste residue treatment device of this embodiment further includes an exhaust gas main pipe for communicating with an external exhaust gas treatment device; the second upper output port 33 on the solvent receiving tank 3 is in communication with the exhaust gas main pipe, and the screw vacuum unit 42 is in gas circuit communication with the exhaust gas main pipe. Ball valves for controlling the on / off of the respective pipelines are provided on the pipeline between the receiving tank input port 35 and the output port of the primary condensation mechanism 2, on the pipeline where the first upper output port 32 is in communication with the secondary condensation mechanism 4, on the pipeline between the second upper output port 33 and the exhaust gas main pipe, and on the pipeline where the screw vacuum unit 42 is in communication with the exhaust gas main pipe. In this embodiment, ball valves are provided at the output and input ports. The setting of the ball valves facilitates the control of the on / off of each pipeline, making it convenient to control each pipeline.

[0044] To ensure that all the liquid solvents condensed in the solvent receiving tank 3 and the secondary condensation mechanism 4 are recycled into the solvent storage tank 5, a solvent transfer assembly 8 is provided on the pipeline between the solvent receiving tank 3 and the solvent storage tank 5, and / or on the pipeline between the secondary condensation mechanism 4 and the solvent storage tank 5; the solvent transfer assembly 8 is used to transport the liquid solvent in the solvent receiving tank 3 and / or the secondary condensation mechanism 4 to the solvent storage tank 5. The solvent transfer assembly 8 in this embodiment includes a transfer ball valve 81, a solvent transfer pump 82, and a manual flange valve 83 arranged in sequence on the pipeline. In this embodiment, first, the lower output port 34 of the solvent receiving tank 3 is connected to the solvent output port of the secondary condensation mechanism 4, and the same solvent transfer assembly 8 is used to communicate with the solvent storage tank 5. During use, the transfer ball valve 81 and the manual flange valve 83 are opened, and the solvent transfer pump 82 is started, so that all the liquid solvents condensed in the solvent receiving tank 3 and the secondary condensation mechanism 4 can be recycled into the solvent storage tank 5.

[0045] As Figure 4 shown, the dry residue discharge system 6 in this embodiment includes a dry residue storage bin 61, a discharge ball valve 62, and a discharge check valve 63 arranged in sequence on the pipeline from the solid output port 13 of the self-cleaning drying mechanism 1 to the dry residue storage bin 61. When the solvent vapor in the drying chamber is almost completely discharged, the heating and pressure reduction operations of the waste residue are stopped. After natural cooling, the discharge ball valve and the discharge check valve 63 are opened, and the dry residue in the drying chamber is discharged into the dry residue storage bin 61. Finally, the dry residue in the dry residue storage bin 61 is bagged for convenient subsequent mobile treatment.

[0046] The use process of the dichloran waste residue treatment device in this embodiment is as follows: First, the waste residue is fed into a horizontal self-cleaning dryer. The stirring shaft and jacket in the dryer are heated by a steam heating system, so that the temperature of the waste residue gradually rises. At this time, the vacuum pump is started to create a negative pressure environment in the drying chamber. The solvent in the waste residue quickly evaporates under the conditions of negative pressure and high temperature. The solvent vapor generated by evaporation enters the primary condensation mechanism 2 and the secondary condensation mechanism 4 through the pipeline. The primary condensation mechanism 2 and the secondary condensation mechanism 4 cool the solvent vapor into a liquid, and the liquid solvent flows into the solvent receiving tank 3. During the entire distillation process, the liquid level sensors of the primary condensation mechanism 2, the secondary condensation mechanism 4, and the solvent receiving tank 3 monitor the solvent recovery situation in real time.

[0047] After the distillation is completed, the solvent transfer assembly 8 is started to transfer the solvents in the secondary condensation mechanism 4 and the solvent receiving tank 3 to the solvent storage tank 5 to prepare for the next treatment. When the solvent in the waste residue is basically evaporated, the steam heating and vacuum pump operations are stopped, and the inside of the drying chamber gradually cools down. At this time, the dry residue discharge system 6 is started to discharge the dried dry residue. The dry residue is in powder form, which is convenient for further treatment or disposal.

[0048] In this embodiment, through the cooperation of vacuum distillation, the primary condensation mechanism 2 and the secondary condensation mechanism 4, the solvent in the dichlone waste residue can be efficiently recovered, reducing resource waste. The device is equipped with an automated control system that can monitor and adjust various parameters during the drying process in real time, reducing manual operation and improving the processing efficiency. At the same time, the dried residue after being processed by this processing device is in powder form, facilitating further processing or disposal and reducing environmental pollution. Additionally, the setting of the solvent storage tank 5 can effectively store the recovered solvent, providing convenience for the next treatment.

[0049] The dichlone waste residue treatment device of this embodiment realizes the efficient recovery of the solvent in the waste residue and the drying treatment of the waste residue, improves the production efficiency, reduces the treatment cost, and has broad application prospects.

[0050] It should be understood that the specific embodiments described above are only used to explain the present invention and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
