Description

Technical Field

[0001] The utility model relates to the technical field of ore pulp reagent addition, in particular to a flotation reagent addition flow control device. Background Art

[0002] After searching, it was found that the "A Flotation Reagent Addition Flow Control Device" disclosed in Chinese Patent Publication No. CN202070405U includes a flotation stirring barrel, a slurry pipe for pressure-transporting fluid slurry, and its discharge port is connected to the stirring barrel. A fluid flotation reagent box is arranged on the upper part of the stirring barrel, and a conveying pipe is connected to the bottom discharge port of the reagent box. A necking port is arranged on the discharge port of the conveying pipe, and a floating ball is movably installed in the conveying pipe located at the necking port. The diameter of the necking port of the conveying pipe is smaller than the diameter of the floating ball. The spherical surface of the lower part of the floating ball is exposed to the discharge port of the conveying pipe. The discharge port of the conveying pipe is vertically connected to the horizontal slurry pipe. The discharge port of the conveying pipe is located in the middle or lower part of the slurry pipe, and the conveying pipe is sealed and connected to the slurry pipe;

[0003] However, this flow control device has some problems. First, the slurry must be stirred after the dosing flow control, which means that the flow detection data can only be obtained after the stirring starts. This lag may make it difficult for the operator or automatic control system to respond to flow changes in time, thus affecting production efficiency and product quality.

[0004] Secondly, due to the delay of flow control, if there is a time difference between dosing and stirring, the flow rate may change during this time difference, and these changes cannot be detected in time. In this case, the accuracy of flow detection will be affected and errors may gradually accumulate.

[0005] Finally, in a production environment where real-time flow monitoring is required, this approach may not meet the requirements. Due to the time difference between dosing and stirring, the flow data may not reflect the actual situation in the production process in real time. This may cause the operator or automatic control system to be unable to make correct decisions in time, thus affecting production efficiency and product quality. Utility Model Content
