Description

Technical Field

[0001] The utility model belongs to the technical field of gold ore flotation, in particular to a flow stabilizing device for maintaining a stable flotation liquid surface. Background Art

[0002] Gold concentrate refers to ore containing metallic gold. Flotation is a common ore dressing method and is also used to extract gold concentrate.

[0003] During the flotation process, gold concentrate is usually crushed and ground, then mixed with one or more chemical reagents and adsorbed or trapped in bubbles to separate and concentrate the metallic gold.

[0004] However, there are some problems in the prior art: during the flotation process of the existing device, when stirring the gold concentrate, the flotation machine model used in the selection section of the existing two-rough, two-fine and four-sweep process is a BF-6 self-priming mechanical stirring flotation machine with an effective volume of 6m 3 ; In the concentration process, there is a serious phenomenon of "flowering" of the slurry in the flotation tank. The foam product scraped out by the scraper is uneven and contains a large amount of slurry, which leads to a low concentration of the concentrate in the first concentration, affecting the separation effect of the second concentration. At the same time, the amount of concentrate in the second concentration is also difficult to control stably, and the concentrate grade does not meet the requirements (too low). In addition, since most of the flotation slurry is allocated to the front end, the amount of slurry entering the back-end scavenging process is relatively small. In the third and fourth scavenging processes, there is a phenomenon of flotation tank dropping, and the grade of the flotation tailings is difficult to be effectively guaranteed. There is often a high-running phenomenon (greater than 1.0g / t). Various flotation indicators cannot reach the ideal state, which has become a major pain point restricting flotation control. Therefore, we propose a flow stabilizing device to maintain a stable flotation liquid level to reduce the generation of foam. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a flow stabilizing device to maintain a stable flotation liquid surface, which solves the problem that during the flotation process of the existing device, when stirring the gold concentrate, the flotation machine model used in the selection section of the existing two-roughing, two-fine and four-sweeping process is BF-6 self-priming mechanical stirring flotation machine, and its effective volume is 6m 3 ; In the concentration process, there is a serious phenomenon of "flowering" of the slurry in the flotation tank. The foam product scraped out by the scraper is uneven and contains a large amount of slurry, which leads to a low concentration of the concentrate in the first concentration, affecting the separation effect of the second concentration. At the same time, the amount of concentrate is difficult to control stably, and the grade of the concentrate does not meet the requirements (is too low). In addition, since most of the flotation slurry is allocated to the front end, the amount of slurry entering the back-end scavenging process is relatively small. In the third and fourth scavenging processes, there is a phenomenon of flotation tank falling, and the grade of the flotation tailings is difficult to be effectively guaranteed. There is often a phenomenon of running high (greater than 1.0g / t), and various flotation indicators cannot reach the ideal state.

[0006] The utility model is a flow stabilizing device for maintaining a stable flotation liquid surface, comprising a support frame and a stirring assembly, the support frame is used to be placed in a gold ore flotation tank, the stirring assembly is fixed on the support frame, and is used to stir liquid operation, the support frame comprises a bottom plate, a support rod and a support plate, a plurality of support rods are provided, a plurality of support rods are located at the upper part of the bottom plate, and the upper part is fixedly connected to the support plate, the output end of the stirring assembly is located between the support plate and the bottom plate, and the support plate is located at the upper part of the output end of the stirring assembly, and is used for vertical flow stabilizing operation. The support frame is used to be placed in a gold ore flotation tank. It comprises a bottom plate, a support rod and a support plate. The support rod is located at the upper part of the bottom plate and is connected to the support plate by a fixed connection, and then the stirring assembly is installed to realize liquid stirring operation, the specific output end of the stirring assembly is located between the support plate and the bottom plate, and the support plate is located at the upper part of the output end of the stirring assembly, and the vertical flow stabilizing operation is realized to prevent turbulence rushing to the liquid surface. When the stirring assembly is used to stir the liquid, the support plate is located at the lower part of the liquid surface, and a relatively stable liquid surface is realized by blocking the turbulence that impacts the liquid surface. This flow stabilizing device plays an important role in the flotation process. By controlling the movement of the liquid, the flotation effect can be improved, the loss of gold concentrate can be reduced, and the concentration of metallic gold can be increased.

[0007] Preferably, the support plate includes a plate body, a circular groove is provided at the bottom of the plate body, and the opening of the circular groove is arranged downward for diversion operation. Since the circular groove is provided at the bottom of the support plate and the opening of the groove is arranged downward, the design is intended to achieve diversion operation. When the stirring assembly stirs the liquid, the generated turbulent flow will be guided into the circular groove of the support plate. Due to the presence of the groove, the turbulent flow is guided downward along the path of the groove. This diversion operation helps to take the turbulent flow away from the liquid surface and guide it to the bottom area of ​​the flotation tank.

[0008] Preferably, the support plate further comprises a baffle, and a plurality of baffles are provided, and the plurality of baffles are evenly fixed in the circular groove at the bottom of the plate body in the circumferential direction for further steady flow operation. In addition to the circular groove, the support plate further comprises a plurality of baffles. These baffles are evenly fixed in the circular groove at the bottom of the support plate, aiming to further achieve steady flow operation.

[0009] The presence of multiple baffles changes the path and speed of liquid flow. When the liquid passes through the circular groove, the baffles will block and guide the liquid, making it more stable when passing through the groove. The circumferential uniform distribution of the baffles ensures that the liquid flows evenly in the groove, avoiding the situation where too much liquid flow is concentrated in a specific area. Through the action of the baffles, the flow of the liquid becomes smoother and more stable. This helps to effectively control the flow environment in the flotation tank, reduce the generation of turbulence, and improve the flotation effect.

[0010] Therefore, the introduction of baffles further optimizes the design of the support plate, achieves more stable flow operation, and improves the efficiency and stability of the flotation process.

[0011] Preferably, the support rod includes a rod body, and an arc groove is provided inside the rod body for lateral steady flow operation. In the design of the support rod, a series of arc grooves are provided inside the rod body, and these arc grooves are located in the vertical direction of the rod body. The purpose is to achieve lateral steady flow operation and fluid control. The setting of these arc grooves allows the fluid to produce different shear and flow in the vertical direction. When the fluid passes through the support rod, the fluid will change under the action of the arc grooves, thereby achieving lateral steady flow operation. The shape and number of the arc grooves can be adjusted according to specific needs. More grooves can produce more flow constraints, making the distribution of the fluid in the lateral direction more uniform and stable. Through the arc grooves of the vertically arranged support rod, the flow of the fluid can be effectively adjusted, and the transfer speed and pressure difference of the fluid in adjacent areas can be controlled. This helps to reduce the turbulence and violent fluctuations of the fluid, thereby improving the efficiency and stability of the fluid treatment process.

The motor is fixedly mounted on the upper part of the support plate, the rotating shaft is fixed at the output end of the motor, the rotating shaft passes through the support plate and extends to the lower part of the support plate, and the propeller is adjustably mounted outside.

[0013] Preferably, the shaft includes a shaft body, and the shaft body is provided with a plurality of screw holes in an equidistant longitudinal array. The stirring paddle includes a sleeve, a blade and a screw. The sleeve is screwed to screw holes at different heights through the screw to achieve height adjustment operation. The blade is provided with a plurality of blades, and the plurality of blades are uniformly fixed on the outside of the sleeve in the circumferential direction. In the stirring assembly, the motor is fixedly mounted on the upper part of the support plate. The motor can provide power to drive the stirring operation. The shaft is fixed to the output end of the motor, thereby being connected to the motor. The shaft extends downward to the lower part of the support plate through the support plate, and the propeller can be adjustably mounted. The propeller is connected to the end of the shaft so that direct drive can be achieved by the rotation of the shaft. The shape and design of the propeller can be selected according to specific needs to achieve the desired stirring effect. When the motor is started, the rotational power of the shaft will be transmitted to the propeller, causing the propeller to start rotating. The rotation of the propeller generates stirring force and shear force, thereby effectively mixing and stirring the liquid, and the position of the propeller can be adjusted as needed according to the liquid level.

[0014] Preferably, two propellers are provided, the two propellers are fixedly mounted outside the rotating shaft, and the blades are tiltedly arranged outside the sleeve. By, two propellers are provided, the two propellers are fixedly mounted outside the rotating shaft, and the blades are tiltedly arranged outside the sleeve, and a combined stirring operation is performed.

[0015] In view of the serious problem of "flowering" of slurry in the flotation cell of the existing flotation system's concentration process, after carrying out process diagnosis on each flotation process on site, it was finally decided to add a gate with flexible height adjustment at the position of the concentration slurry inlet pipe to reasonably control the concentration slurry inlet amount. Through actual verification in on-site production, this method effectively solved the serious problem of "flowering" in the above-mentioned concentration process, and the slurry surface in the flotation cell became more stable and orderly. The flotation production index data also verified the feasibility of this method.

When the stirring assembly is used to stir the liquid, the support plate is located below the liquid surface and a relatively stable liquid surface is achieved by blocking the turbulence that impacts the liquid surface. This flow stabilizing device plays an important role in the flotation process. By controlling the movement state of the liquid, the flotation effect can be improved, the loss of gold concentrate can be reduced, and the concentration of metallic gold can be increased;
