DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0023] With reference to Figures 1-4 In the field of mineral flotation processing, in order to realize efficient, accurate and automatic flotation operation, the utility model provides an automatic control flotation column with exquisite structure design and perfect function, the detailed structure and operation mechanism of which are as follows:
[0024] The main structure of the flotation column covers key components such as the column body 1, the mixing box 2 and the circulating pump 6. Among them, the column body 1 is the core area of flotation, and the side surface is reasonably arranged with the tailing pipe 4 and the circulating pipe 5. The tailing pipe 4 shoulders the heavy responsibility of successfully discharging the remaining tailings after flotation from the column body 1, ensuring that the tailings can timely and orderly leave the flotation process, avoiding interference with the subsequent flotation operation.
[0025] The circulating pipe 5 is closely connected with the subsequent circulating system, and builds a key channel for the recycling of the ore pulp.
[0026] The mixing box 2 is the pre-mixing hub of the ore pulp, reagents and air, and is stably connected with the column body 1 through the feed pipe 3, ensuring that the pre-mixed materials can be smoothly and efficiently conveyed to the column body 1 for flotation operation.
[0027] Above the mixing box 2, the ore pulp pipe 9 is accurately arranged, which is the only way for the ore pulp to enter the mixing box 2.
[0028] The circulating pump 6 is the power core of the entire circulating system, which is seamlessly connected with the circulating pipe 5 through the connecting pipe 7, and at the same time, completes the closed-loop connection with the ore pulp pipe 9 through the feeding pipe 8, so as to realize the circulation of the ore pulp from the bottom of the column body 1 to the mixing box 2, greatly improving the utilization rate of mineral resources and reducing unnecessary waste.
[0029] Especially worth noting is that the reagent pipe 10 and the air pipe 11 are ingeniously installed on the ore pulp pipe 9, and the three work together to provide the core elements for the mixing reaction in the mixing box 2.
[0030] Among them, the air pipe 11 is innovatively installed with the driving shaft 17, when the air flows at high speed through the air pipe 11, the driving shaft 17 can be driven to rotate by the specially designed blade 18.
[0031] To realize the effective transmission and conversion of power, the transmission shaft 15 is installed on the mixing box 2, and the driving shaft 17 is connected with the transmission shaft 15 through a set of precisely designed rotating mechanism.
[0032] In the material injection link, the medicine pipe 10 and the air pipe 11 are both arranged in an inclined manner, and the inclined angle is accurately set to 30 degrees. According to the fluid mechanics principle, the unique inclined design can promote the medicine and air to be injected into the mixing box 2 at the best flow rate and flow direction, avoid the problems such as material accumulation and uneven injection, and ensure that the mixing reaction in the mixing box 2 is in an ideal state from the beginning.
[0033] The stable operation of the mixing box 2 cannot be realized without a reliable support structure. Therefore, the support frame 14 is installed on the mixing box 2, and the installation position and motion trail of each component around the mixing box 2 are fully considered to provide solid support while effectively avoiding interference with other components. The driving shaft 17 penetrates the support frame 14 and can stably and continuously rotate under the assistance of the support frame 14, thereby laying a solid foundation for the entire power transmission system.
[0034] In addition, to ensure the accurate control of the material flow direction, valves are arranged in the ore pulp pipe 9, the medicine pipe 10 and the air pipe 11, and the three valves are all one-way valves. The arrangement of the one-way valves is like a series of accurate "checkpoints" that strictly control the in-out direction of the ore pulp, the medicine and the air, prevent the occurrence of backflow phenomenon, and make the entire flotation process proceed in an orderly manner according to the predetermined scientific path, thereby effectively guaranteeing the efficiency and stability of the flotation operation.
[0035] When the utility model is used, the flotation reagent, the air and the circulating ore pulp are injected into the mixing box 2 through the medicine pipe 10, the air pipe 11 and the ore pulp pipe 9 at a high speed, and at the same time, the air passes through the air pipe 11, the blade 18 drives the driving shaft 17 to rotate, the driving shaft 17 cooperates with the driving gear 13 and the transmission gear 12 to drive the transmission shaft 15 to rotate, the transmission shaft 15 drives the mixing rod 16 to rotate, and with the rotation of the transmission shaft 15 and the mixing rod 16, the gas-liquid-solid mixing operation in the mixing box 2 is realized, and then the material is injected into the column 1 through the feeding pipe 3.
[0036] The tailings are discharged through the tailings pipe 4 of the column 1, the mineral combined with the bubbles floats to the top of the column 1 and overflows into the froth tank on the column 1, and finally is discharged through the concentrate pipe matched with the froth tank on the column 1 (the froth tank and the concentrate pipe are not drawn, and can be referred to the prior art disclosure), thereby realizing efficient flotation.
[0037] The bottom slurry is extracted from the matching circulation pipe 5 and the connecting pipe 7 by the circulating pump 6, and then re-enters the slurry pipe 9 by the feeding pipe 8, mixes with the injected medicament and air in the mixing box 2, and is injected into the column 1 again.
[0038] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
