Detailed Implementation

[0019] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-3 As shown, this utility model provides a blending device for chlorinated paraffin raw materials, including a support 1. A PLC controller 8, multiple raw material tanks 2, a dynamic mixing tank 3, a detection tank 5, and a collection tank 7 are mounted on the support 1. Each raw material tank 2 is connected to the dynamic mixing tank 3 via a pipe. A mass flow meter 10 and an electric regulating valve 11 are sequentially installed on the pipe between the raw material tank 2 and the dynamic mixing tank 3. The mass flow meter 10 and the electric regulating valve 11 are electrically connected to the PLC controller. The PLC controller controls the opening degree of the electric regulating valve 11 according to a preset program, and the mass flow meter 10 monitors the flow rate of the raw materials in real time, thereby precisely controlling the amount of various raw materials entering the dynamic mixing tank 3.

[0021] The outlet of the dynamic mixing tank 3 is connected to one end of the testing tank 5 via a pipeline. A solenoid valve is installed on the pipeline between the dynamic mixing tank 3 and the testing tank 5, and the solenoid valve is electrically connected to the PLC controller. The opening and closing of the solenoid valve is controlled by the PLC controller to realize the transportation of the mixed raw materials to the testing tank 5.

[0022] The testing tank 5 is equipped with a testing mechanism 9, which includes a component analyzer, a densitometer, and a viscometer. The testing mechanism is electrically connected to the PLC controller. The testing mechanism 9 detects parameters such as the composition, density, and viscosity of the blended raw materials in real time and transmits the data to the PLC controller.

[0023] The other end of the test tank 5 is connected to the dynamic mixing tank 3 through the return pipe 14. The return pipe 14 is equipped with a transfer pump 6, which is electrically connected to the PLC controller 8. When the test result does not meet the requirements, the PLC controller controls the transfer pump 6 to work and transfer the raw materials in the test tank 5 back to the dynamic mixing tank 3 through the return pipe 14 for remixing.

[0024] The outlet of the testing tank 5 is connected to the collection tank 9 via a pipeline. A solenoid valve is installed on the pipeline between the testing tank 5 and the collection tank 7. This solenoid valve is electrically connected to the PLC controller. When the test result meets the requirements, the PLC controller controls this solenoid valve to open and transport the qualified raw materials to the collection tank 7.

[0025] A stirring mechanism is installed inside the dynamic mixing tank 3, and a transmission mechanism 4 that drives the stirring mechanism is installed at one end of the dynamic mixing tank 3. A control box 12 is installed at one end of the dynamic mixing tank 3, and a variable frequency motor 13 is installed on the control box 12. A drive bevel gear 15 is installed at the output end of the variable frequency motor 13. A drive shaft 18 that penetrates into the interior of the dynamic mixing tank 3 is installed on the inner wall of the control box 12. A bushing 17 is sleeved at the end of the drive shaft 18. A driven bevel gear 16 that meshes with the drive bevel gear 15 is installed at the end of the drive shaft 18 and the end of the bushing 17, respectively. A ring frame 19 is installed on the outer surface of the bushing 17. The end face of the ring frame 19 is in contact with the inner wall of the dynamic mixing tank 3. A first stirring plate 20 is evenly installed at the end of the ring frame 19 near the drive shaft 18. A fixing sleeve 21 is evenly installed on the outer surface of the drive shaft 18. A second stirring plate 22 is installed on the outer surface of the fixing sleeve 21. The first stirring plate 20 and the second stirring plate 22 are inclined along the centerline of the transmission shaft 18, and the inclination directions of the first stirring plate 20 and the second stirring plate 22 are opposite. The variable frequency motor 13 drives the active bevel gear 15 to rotate, which in turn drives the two driven bevel gears 16 to rotate, so that the transmission shaft 18 and the bushing 17 rotate in opposite directions, thereby driving the first stirring plate 20 and the second stirring plate 22 to efficiently stir the raw materials in the dynamic mixing tank 3.

[0026] When using this device: First, the raw materials required for the production of various chlorinated paraffins are stored in the corresponding raw material tanks 2. Then, according to the preset raw material ratio program, the PLC controller 8 controls the opening of the electric regulating valve 11, and the mass flow meter 10 monitors the flow rate of the raw materials in real time. The precisely measured raw materials are then transported to the dynamic mixing tank 3 through pipelines. Then, the variable frequency motor 13 is started, which drives the active bevel gear 15 to rotate. The active bevel gear 15 drives the driven bevel gear 16 to rotate, which in turn causes the transmission shaft 18 and the bushing 17 to rotate in opposite directions. The first stirring plate 20 and the second stirring plate 22 stir and mix the raw materials in the dynamic mixing tank 3. The mixed raw materials are then transported to the detection tank 5 through pipelines. The component analyzer, densitometer, and viscometer in the detection mechanism 9 detect the raw materials and transmit the detection data to the PLC controller 8. If the test results do not meet the requirements, the PLC controller 8 controls the conveying pump 6 to work, and conveys the raw material back to the dynamic mixing tank 3 through the return pipe 14 for re-mixing; if the test results meet the requirements, the PLC controller 8 controls the solenoid valve on the pipeline between the test tank 5 and the collection tank 7 to open, and conveys the qualified raw material to the collection tank 7. Finally, the collection tank 7 collects and stores the qualified chlorinated paraffin raw material for subsequent use in the production of chlorinated paraffin.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
