Among them, the first temporary storage tank 100 is used for storing crude syrup. The first temporary storage tank 100 is connected to a first reaction barrel 110 through a first pipeline. The first reaction barrel 110 is successively connected to a foaming device 120, a second reaction barrel 130 and a floating device 140; the adding device includes a second temporary storage tank 200 and two third temporary storage tanks 210. The second temporary storage tank 200 is used for storing flocculant. The second temporary storage tank 200 is connected to the second reaction barrel 130 through a second pipeline. The two third temporary storage tanks 210 are respectively used for storing phosphoric acid and lime milk. The third temporary storage tank 210 is connected to the first reaction barrel 110 through a third pipeline. The second pipeline and the third pipeline are both provided with a first output pump 300 and a first flowmeter 310. The first output pump 300 is electrically connected to a first frequency converter 320; the control device is electrically connected to the first frequency converter 320 and the first flowmeter 310. The control device is used for receiving the flow data collected by the first flowmeter 310 and controlling the first frequency converter 320 to change the output of the corresponding first output pump 300, so that the second temporary storage tank 200 and the third temporary storage tank 210 perform corresponding proportional outputs.

[0026] The high-precision syrup floating control system with the above structure, when in use, the crude syrup in the first temporary storage tank 100 is transported to the first reaction barrel 110 through the first pipeline, and then phosphoric acid and lime milk are transported to the first reaction barrel 110 through the third pipeline, so that calcium phosphate particles with the function of adsorbing impurities are formed in the first reaction barrel 110. Then, the solution in the first reaction barrel 110 is transported to the bubbler 120 and the second reaction barrel 130. The flocculant in the second temporary storage tank 200 is transported to the second reaction barrel 130 through the second pipeline, so that the calcium phosphate particles can cooperate with the bubbles to form flocs with a lighter specific gravity under the action of the bubbler 120 and the flocculant. Finally, the flocs float in the flotator 140 to achieve the effect of syrup purification, and thus transparent and shiny syrup is obtained. Among them, phosphoric acid, lime milk and flocculant are all transported by the corresponding first output pump 300. The first output pump 300 is connected with a first frequency converter 320. The control device adjusts the output frequency of the first frequency converter 320 according to the data of the corresponding first flowmeter 310, so as to change the rotational speed output of the corresponding first output pump 300, and then automatically and accurately control the output flow of phosphoric acid, lime milk and flocculant, which is beneficial to improving the accuracy of the addition device for outputting different materials, and thus beneficial to improving the purification effect of the syrup.

[0027] See Figure 1 , Further, the first pipeline is successively connected with a second output pump 150 and a second flowmeter 160. The second flowmeter 160 is located between the first temporary storage tank 100 and the first reaction barrel 110. The second output pump 150 is electrically connected with a second frequency converter 170, and the second frequency converter 170 is electrically connected with the control device. Specifically, the control device adjusts the output frequency of the second frequency converter 170 according to the data of the corresponding second flowmeter 160, so as to change the rotational speed output of the corresponding second output pump 150, and then automatically and accurately control the output flow of the crude syrup, which is beneficial for people to adjust the addition ratio of other auxiliary materials according to the flow of the crude syrup, so that the addition device can be safe and reliable.

[0028] It can be understood that the first flowmeter 310 and the second flowmeter 160 adopt high-precision flowmeters, such as electromagnetic flowmeters or mass flowmeters, so as to provide more accurate flow detection signals for the control device. When in use, the output ratio of the flow rates among the main syrup, phosphoric acid, lime milk and flocculant is set according to the production process requirements. Then, the second flowmeter 160 measures the actual output flow rate of the main syrup, and the three first flowmeters 310 respectively measure the actual output flow rates of phosphoric acid, lime milk and flocculant. The control device synchronously adjusts the output frequencies of the corresponding first frequency converter 320 and the second frequency converter 170 according to the set output ratio, and finally makes the actual output flow rates of the main syrup, phosphoric acid, lime milk and flocculant reach the set ratio requirements, so as to improve the control accuracy and stability of the system for adding materials.

The second input pipe is successively connected with a third regulating valve 520. The control device further includes a third valve controller 530 electrically connected to the third regulating valve 520. Specifically, the high-temperature steam is conveyed into the interior of the high-level tank through the second input pipe, thereby heating the crude syrup in the high-level tank. By using the cooperation of the third valve controller 530 and the third regulating valve 520, it is beneficial to change the flow output of the high-temperature steam in the second input pipe, thereby changing the heating rate of the crude syrup in the high-level tank and ultimately changing the heating temperature of the crude syrup.

[0033] See Figure 2 , Further, it further includes a second temperature sensor 540 provided on the first pipeline. The second temperature sensor 540 is located between the high-level tank and the first reaction tank 110.

[0034] Further, the first temporary storage tank 100 is provided with a liquid level sensor. The liquid level sensor is electrically connected to the control device, and the control device is electrically connected to an alarm module.
