[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] The stirring assembly 7 is welded to the top of the outer wall of the mixing vessel 1 through the connecting seat 701 provided therein, and the connecting seat 701 is provided with a driving bevel gear 702 through the output end of the servo motor, and the driving bevel gear 702 is respectively meshed and connected with an upper driven bevel gear 703 and a lower driven bevel gear 704, and the upper driven bevel gear 703 and the lower driven bevel gear 704 are respectively rotatably connected to the upper and lower ends of the inner wall of the connecting seat 701, and the lower driven bevel gear 704 is welded to the top of the turntable 706 through an outer driving rod 705 running through the axis center thereof, and a first stirring member 707 is distributed in an annular manner on the surface of the turntable 706, and an inner driving rod 708 is welded at the axis center of the upper driven bevel gear 703, and a second stirring member 709 is provided on the surface of the inner driving rod 708.
[0024] In this embodiment, Figure 1 and Figure 2 As shown, the mixing vessel 1 adopts a double-layer structure, and a resistance wire electrically connected to the temperature controller 9 is arranged in the cavity in the middle of the mixing vessel 1; the inner walls of the mixing vessel 1 and the diversion box 2 are made of ceramic material, which has high corrosion resistance and is not easy to stick to the wall, and can effectively avoid the adhesion of raw materials with poor fluidity, and the temperature controller 9 (model AI-208) is used to adjust the temperature according to different reaction requirements, effectively avoiding the solidification of the raw materials due to too low temperature.
[0025] In this embodiment, Figure 2 , Figure 4 and Figure 5As shown, the bottom wall inside the diverter box 2 is sloped, and one end of the second delivery port 6 is attached to the lowest point of the bottom wall of the diverter box 2, and the other end of the second delivery port 6 passes through the through hole on the surface of the mixing vessel 1, and the mixing vessel 1 is connected to one side of the diverter box 2 through the second delivery port 6; compared with directly delivering the raw materials on the inner wall of the raw material box 3 to the inside of the mixing vessel 1, these raw materials with poor fluidity and high viscosity are very easy to adhere to the inner wall of the pipeline during the delivery process, resulting in the amount of raw materials finally entering the mixing vessel 1 not reaching the final required ratio value, thereby affecting the experimental data, the raw materials are pre-transferred to the diverter box 2 through the raw material box 3, and the scraper 12 structure inside the diverter box 2 is used to push the raw materials, and the second delivery port 6 is inclined. The structural form of the two that cooperates with each other can effectively reduce the loss of raw materials during the delivery process, which helps to ensure that the amount of raw materials finally entering the mixing vessel 1 reaches the expected ratio value, thereby improving the accuracy and repeatability of the experimental data.
[0026] In this embodiment, Figure 5 As shown, the scraper 12 is trapezoidal, and the bottom of the scraper 12 is attached to the bottom of the diverter box 2, and the scraper 12 forms a transmission structure inside the diverter box 2 through the reciprocating screw 11; the scraper 12 can be attached to the bottom wall of the diverter box 2 through the transmission structure of the reciprocating screw 11, and under the reciprocating transmission structure, the raw materials remaining in the diverter box 2 are pushed into the mixing vessel 1 through the second conveying port 6 to avoid the loss of raw materials.
[0027] In this embodiment, Figure 1 As shown, the first delivery port 5 is electrically connected to the PLC controller 13 through the flow meter and solenoid valve provided on its surface, and the second delivery port 6 is located at one end of the diverter box 2 and is provided with a solenoid valve; the flow meter (model MIK-LDG-SUPDN-25) can deliver the set parameters to the inside of the diverter box 2. Because the raw materials will partially remain inside the pipeline when being transported through the first delivery port 5, a pressure sensor (model JX-KG-B3) is provided at the bottom of the diverter box 2 to ensure the accuracy of the raw material value entering the diverter box 2. When the medium capacity in the diverter box 2 reaches a certain level, the pressure sensor (model JX-KG-B3) is provided at the bottom of the diverter box 2. When the temperature rises, the pressure applied to the pressure sensor will also increase. The pressure sensor converts the pressure change into an electrical signal and transmits it to the PLC controller 13. When the PLC controller 13 receives the pressure sensor signal and determines that the liquid capacity in the box has reached a sufficient level, it will send a control signal to the solenoid valve, and one end of the first delivery port 5 closes the channel through the solenoid valve to stop delivery, and the second delivery port 6 opens the channel through the solenoid valve to deliver to the mixing vessel 1. Compared with direct delivery, the indirect supply method is more conducive to improving the accuracy of quantitative delivery of raw materials and greatly reducing the phenomenon of medium loss due to residue.
[0028] In this embodiment, Figure 3As shown, the upper driven bevel gear 703 and the lower driven bevel gear 704 form a relative rotational motion through the active bevel gear 702, and the inner driving rod 708 penetrates the outer driving rod 705 and the turntable 706 at the bottom thereof and is rotatably connected to the bottom of the turntable 706, and the second stirring member 709 and the first stirring member 707 are in a relative rotational structure, and the first stirring member 707 is located at the periphery of the second stirring member 709; the relative motion structure of the upper driven bevel gear 703 and the lower driven bevel gear 704 can realize the first stirring member 707 and the second stirring member 709 stirring in a relative rotational manner, and this reverse stirring method can better mix the internal raw materials, effectively promote the flow of raw materials, and improve the efficiency of rapid fusion for processing such raw materials with poor fluidity, thereby saving time.
[0029] The use method and advantages of the utility model: When the mixing kettle with a quantitative feeding structure is used, the working process is as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, raw materials for mixing are stored in the raw material box 3, which are transported to the inside of the diverter box 2 through the pipeline and the first delivery port 5 by the peristaltic pump 4 (model LFP104BLW). Compared with the water pump, the peristaltic pump 4 has the advantages of corrosion resistance and viscosity resistance. The medium is accumulated in the diverter box 2 during continuous transportation. When the medium capacity in the diverter box 2 reaches a certain level, the pressure applied to the pressure sensor will also increase. The pressure sensor converts this pressure change into an electrical signal and transmits it to the PLC controller 13. When the PLC controller 13 receives the pressure sensor signal and determines that the liquid capacity in the box has reached a sufficient level, it will send a control signal to the solenoid valve, and one end of the first delivery port 5 stops the delivery through the solenoid valve to close the channel, and one side of the second delivery port 6 opens the channel through the solenoid valve to transport to the mixing vessel 1. At the same time, the inner layer of the mixing vessel 1 The resistance wire is adjusted to a suitable temperature by the temperature controller 9, and at the same time, the scraper 12 slides back and forth inside the diverter box 2 through the transmission structure of the reciprocating screw 11 to accelerate the conveying speed of the medium. The operator can observe whether the internal medium is conveyed thoroughly through the visual port on the top of the diverter box 2. When the raw material is completely discharged into the mixing vessel 1, the servo motor driving bevel gear 702 is driven by the power supply to rotate, so that the upper driven bevel gear 703 and the lower driven bevel gear 704 meshing at the upper and lower ends thereof rotate in the opposite direction, and the outer drive rod 705 and the inner drive rod 708 coaxially connected to the upper driven bevel gear 703 and the lower driven bevel gear 704 respectively rotate in the opposite direction, so that the first stirring member 707 and the second stirring member 709 are relatively rotated to fully stir the raw material inside the mixing vessel 1, and the mixed raw material can be extracted through the material outlet 10.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
