The number of the stirring blades 3 is ten. A heating rod 4 is arranged in the inner cavity of the stirring blade 3. A motor 5 is fixedly connected to the left side of the stirring tank 1. The output shaft of the motor 5 penetrates into the inner cavity of the stirring tank 1 and is in transmission connection with the left end of the rotating column 2. A cleaning mechanism 6 is arranged in the inner cavity of the stirring tank 1. A temperature sensor 7 is arranged at the lower end on the right side of the stirring tank 1, and a PLC controller 8 is arranged at the upper end on the right side of the stirring tank 1. An alarm 9 is arranged at the center of the top of the stirring tank 1. The output end of the temperature sensor 7 is electrically connected to the input end of the PLC controller 8, and the output end of the PLC controller 8 is electrically connected to the input ends of the heating rod 4 and the alarm 9;

[0024] The cleaning mechanism 6 includes a scraper 601. The scraper 601 is located at the end of the stirring blade 3 away from the rotating column 2 and is fixedly connected to one side of the stirring blade 3. The number of the scrapers 601 is two. The side of the scraper 601 away from the stirring blade 3 is in contact with the inner wall of the stirring tank 1. An annular pipe 602 is arranged on the left side of the inner cavity of the stirring tank 1, and a water spraying pipe 603 is fixedly communicated with the right side of the annular pipe 602.

[0025] As Figures 1-4 shown, the stirring tank 1 is used to provide a stirring space for toluene raw materials for toluene production work. The motor 5 is used to drive the rotating column 2 to rotate, and the rotating column 2 is used to drive the stirring blades 3 to rotate. When the stirring blades 3 rotate, they can stir the raw materials inside the stirring tank 1, thereby accelerating the mixing efficiency of the raw materials and further accelerating the production efficiency. The heating rod 4 can heat the inside of the stirring tank 1. In cooperation with the temperature sensor 7 and the plc controller 8, the temperature can be kept within a suitable range, thereby further accelerating the production efficiency of toluene. When the temperature inside the stirring tank 1 is abnormal, the alarm 9 can send an alarm to the staff. The cleaning mechanism 6 can scrape off the residual toluene products on the inner wall of the stirring tank 1 and can wash the inner wall of the stirring tank 1 at the same time, reducing the residues attached to the inner wall, thereby preventing the residues from affecting the stirring effect of the next batch and improving the quality of subsequent finished products.

[0026] Embodiment 2

[0027] Referring to Figure 4 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0028] In this embodiment, a partition plate 604 is fixedly connected to the left side of the inner cavity of the stirring tank 1. The left side of the annular pipe 602 is fixedly connected to the right side of the partition plate 604. The rotating column 2 is movably connected to the inner wall of the partition plate 604 through a bearing.

[0029] The left side of the top of the stirring tank 1 is fixedly communicated with a water delivery pipe 605. The lower end of the water delivery pipe 605 penetrates through the partition plate 604 and is fixedly communicated with the annular pipe 602.

[0030] As Figure 4 shown, the scraper 601 rotates along with the stirring blade 3. When the scraper 601 rotates, it can scrape off the residues adhering to the inner wall of the stirring tank 1. At the same time, the water delivery pipe 605 can be communicated with an external water pipe to deliver water into the inside of the annular pipe 602. The annular pipe 602 then diverts the water flow into the inside of a plurality of spray pipes 603. The water flow is sprayed onto the inner wall of the stirring tank 1 through the spray pipes 603 to wash the residues. At the same time, after starting the motor 5, the stirring blade 3 and the scraper 601 stir the water flow, which can wash the residues remaining on the surfaces of the rotating column 2, the stirring blade 3, and the scraper 601, thereby improving the cleaning effect on the residues.

[0031] Embodiment 3

[0032] Referring to Figure 1 and 2 , this is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, a feeding pipe 10 is fixedly connected to the right side of the top of the stirring tank 1, and a sealing cover is detachably connected to the top of the feeding pipe 10.

[0034] A discharge pipe 11 is fixedly connected to the bottom of the stirring tank 1, and a solenoid valve 12 is arranged on the surface of the discharge pipe 11.

[0035] Both sides of the bottom of the stirring tank 1 are fixedly connected with support plates 13, and the bottom of the support plates 13 is fixedly connected with a bottom plate 14.

[0036] As Figure 1 and 2 shown, the feeding pipe 10 serves to facilitate the addition of production raw materials into the stirring tank 1, the discharge pipe 11 serves to facilitate the discharge of water or toluene finished products inside the stirring tank 1, and the support plates 13 and the bottom plate 14 are used to support the stirring tank 1 to improve the stability of the stirring tank 1 during use.

[0037] During use, production raw materials are added into the stirring tank 1 through the feeding pipe 10. After the addition is completed, the heating rod 4 and the motor 5 are started, and the temperature sensor 7, the PLC controller 8, and the alarm 9 are started synchronously with the heating rod 4. The heating rod 4 heats the inside of the stirring tank 1, and the motor 5 drives the rotating column 2 to rotate. The rotating column 2 is used to drive the stirring blades 3 to rotate. When the stirring blades 3 rotate, they can stir the raw materials inside the stirring tank 1, thereby accelerating the mixing efficiency of the raw materials and further accelerating the production efficiency. At the same time, the temperature sensor 7 detects the temperature inside the stirring tank 1 and controls the opening and closing of the heating rod 4 according to the detection result. At the same time, when the temperature inside the stirring tank 1 is too high, the PLC controller 8 will start the alarm 9 to alert the staff. The stirred finished product is discharged through the discharge pipe 11. When cleaning the inside of the stirring tank 1, the water delivery pipe 605 is connected to an external water pipe, and the motor 5 is started. The scraper 601 will rotate with the stirring blades 3. When the scraper 601 rotates, it can scrape off the residues adhering to the inner wall of the stirring tank 1. At the same time, the water delivery pipe 605 delivers water into the inside of the annular pipe 602, and the annular pipe 602 then diverts the water flow into the inside of a plurality of spray pipes 603. The water flow is sprayed onto the inner wall of the stirring tank 1 through the spray pipes 603 to wash the residues. During this process, the water flow can wash the attachments remaining on the surfaces of the rotating column 2, the stirring blades 3, and the scraper 601, thereby improving the cleaning effect on the residues.
