The stirring mechanism 200 also includes a first stirring blade 203 and a second stirring blade 204 assembled on the shaft component 201, wherein the first stirring blade 203 and the second stirring blade 204 are both configured as spiral blades, and the effective diameter of the second stirring blade 204 is greater than the effective diameter of the first stirring blade 203;

[0039] In some embodiments, the container component 100 further includes a heating structure 205 , which is installed based on the container component 100 and configured to heat the material in the processing zone 104 .

[0040] Reference Figure 1 and 2The metering assembly includes a box body component 300, which is mounted on the side wall portion 100b of the container portion 100 and extends along the length direction of the side wall portion 100b (i.e., the direction of the axis O). Specifically, the box body component 300 has a top plate portion 300a, a bottom plate portion 300c and a peripheral wall portion 300b, wherein the top plate portion 300a is configured as a horizontally arranged plate-like component, and the bottom plate portion 300c is configured as an inclined plate-like component, that is, the bottom plate portion 300c is arranged at an angle to the horizontal plane. Specifically, the bottom plate portion 300c has a first end connected to the container part 100 and a second end extending upwardly and obliquely away from the first end, and the angle between the line connecting the first end and the second end of the bottom plate part 300c and the horizontal line is defined as the inclination angle of the bottom plate part 300c. In some embodiments, the inclination angle is between 5 and 30°.

[0041] Reference Figure 2 The peripheral wall portion 300b has a portion that overlaps with the side wall portion 100b of the container component 100. In some embodiments, the portion of the peripheral wall portion 300b of the box component 300 is in contact with the portion of the side wall portion 100b of the container component 100, that is, the portion of the peripheral wall portion 300b of the box component 300 is designed based on the side wall of the container component 100. In other embodiments, a portion of the container component 100 is constituted as a portion of the peripheral wall portion 300b of the box component 300. For the convenience of description, the portion where the peripheral wall portion 300b of the box component 300 overlaps with the side wall portion 100b of the container component 100 is The control device is generally referred to as a connecting portion 400. In some embodiments, the control device is provided with a connecting port 401 on the connecting portion 400. The connecting port 401 is used to realize the flow of materials between the box part 300 and the container part 100, so that the liquid level in the container part 100 is consistent with the liquid level in the box part 300, and the liquid level in the box part 300 can be kept stable during the stirring of the materials in the container part 100. In some embodiments, the connecting port 401 is configured to be connected in the height direction (i.e., the length direction of the side wall 100b of the container part 100) and the width direction (i.e., Figure 2 The connecting opening 401 extends in a direction perpendicular to the paper surface, and the endpoints in the height direction are marked as the upper endpoint 401a and the lower endpoint 401b, and the endpoints in the width direction are marked as the front end point 401c and the rear end point 401d (refer to Figure 3), in some embodiments, the lower end point 401b of the communication port 401 is located at the first end position of the bottom plate portion 300c, the upper end point 401a is located at a height not greater than 2 / 3 of the set high liquid level (based on the liquid level in the container component 100), and the distance between the front end point 401c and the rear end point 401d is the same as the width of the box component 300. For example, the box component 300 is 200*200*1000mm in size for illustration (where 1000mm represents the height of the connecting portion 400), and correspondingly, the specification of the communication port 401 is 200*500mm;

[0042] In some embodiments, the control device is provided with a breathing port 402 at the top of the connecting portion 400, which is used to ensure that the box and the container remain unobstructed and not pressurized when the liquid level in the container fluctuates, and to ensure that the liquid level rises or falls naturally. In some embodiments, the area of ​​the breathing port 402 is 3% to 10% of the area of ​​the connecting port 401. Exemplarily, when the specification of the connecting port is 200*500mm, the breathing port 402 is configured as a circular hole with a diameter of 100mm; further, the end cover portion 100a is provided with a breathing valve 403 near the breathing port 402.

[0043] Reference Figure 1 and 2 In some embodiments, the measuring component further comprises a liquid meter, and the liquid level meter 500 is configured to measure the liquid level height in the box part 300. Since the interiors of the container part 100 and the box part 300 are connected via the connecting port 401, that is, the liquid level heights in the container part 100 and the box part 300 are kept consistent, correspondingly, the liquid level meter 500 can measure the liquid level heights in the box part 300 and the container part 100. In some embodiments, the liquid level meter 500 is configured as a radar level meter 500, which is installed on the top plate portion 300a of the box part 300 and can realize non-contact measurement of the liquid level, thereby avoiding measurement errors caused by the virtual height of the liquid level caused by the stirring of the material in the container part 100.

[0044] Reference Figure 1In some embodiments, the control device further comprises a spray structure 600, which is configured to clean the box component 300, that is, to remove the material adhering to the inner wall of the box component 300, so as to avoid the residual material from affecting the subsequent processing. For example, the spray structure 600 can output a cleaning liquid (such as oily wastewater with a temperature not less than 70°C, steam or hot water and / or clean water with a temperature greater than 80°C), and the cleaning liquid is configured to dissolve or melt the material adhering to the inner wall of the box component 300, so as to achieve the cleaning of the inner wall of the box component 300. Cleaning, in some embodiments, the spray structure 600 includes a spray head, which is connected to an external cleaning liquid storage container (not shown in the figure) through a pipeline. The cleaning liquid is supplied to the spray head from the external storage container, and flows to the inner wall of the box part 300 through the spray head, so that the material adhering to the inner wall of the box part 300 is dissolved or melted, and enters the container part 100 through the flow port along with the cleaning liquid and is discharged from the discharge port 102. Exemplarily, the above-mentioned spray head is installed at one end of the top plate 300a of the box part 300 away from the container part 100.

[0045] In some embodiments, the peripheral wall portion 300b of the box component 300 is provided with a cleaning port 301 at the end away from the container component 100, and a large-diameter flange is installed at the cleaning port 301, which can be opened during the startup or shutdown of the device to clean the residual materials in the box component 300.

[0046] In some embodiments, the control device further includes a control unit 700 for realizing automatic control of the device. Specifically, the control unit 700 can control the feeding, discharging and cleaning operations based on the liquid level data transmitted by the liquid level meter 500. For example, the control unit 700 is a PLC control system as an example to illustrate it:

[0047] In the process of using the device for liquid level monitoring and control of the container component 100, the operator sets the highest and lowest liquid level heights to be controlled on the PLC control system according to the operating steps, and transmits the liquid level height information to the PLC control system. The radar level meter 500 measures the material level in the container in real time, and the radar level meter 500 transmits the real-time measured liquid level information to the PLC control system. The PLC control system makes an alarm reminder based on the real-time measured liquid level information of the radar level meter 500 and controls the start-up of the pump body of the feed port 101, thereby realizing smooth control of the liquid level in the container.
