Description

Technical Field

[0001] This invention belongs to the technical field of laboratory flotation equipment, specifically a novel flotation unit. This invention can fulfill the functions of conventional flotation equipment with the same throughput, and also possesses the functions of microbubble cavitation flotation equipment. This flotation unit can optimize the operation of conventional laboratory flotation units. Background Technology

[0002] Problems and shortcomings of existing laboratory flotation units: Existing laboratory flotation units have limited functions, difficulty in draining liquid, unstable liquid level, and difficulty in thoroughly cleaning flotation equipment, resulting in unstable flotation experimental parameters; flotation equipment is easily damaged and difficult to repair; in complex flotation processes, flotation cells need to be frequently loaded and unloaded; cavitation experiments of slurry require specific flotation cells for cavitation of the slurry; flotation foam distribution is affected by the space occupied by the flotation unit, resulting in small flotation space and incomplete foam scraping. Summary of the Invention

[0003] This invention aims to address the problems of existing laboratory flotation units, such as difficulty in cleaning, cumbersome operation, limited functionality, small flotation space, and bulky and easily worn flotation equipment, by optimizing the laboratory flotation unit.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A multifunctional composite flotation unit is characterized by: mainly including a right side plate (1) of the flotation cell, a rear side plate (2) of the flotation cell, a left side plate (3) of the flotation cell, and a bottom plate (4) of the flotation cell. The flotation cell is composed of two sections spliced ​​together, which can be assembled according to the joint (5) in the middle of the flotation cell. The right side plate (1) of the flotation cell is designed with a slurry discharge hole (7), which can be assembled with a cavitation device (11); the rear side plate (2) of the flotation cell is designed with a multifunctional connection hole (8), which can be assembled with a multi-hole rod aeration device (12), a temperature measuring instrument (13), a pH measuring instrument (14), and a rod heater (15); the left side plate (3) of the flotation cell is designed with a liquid discharge hole (9); the bottom plate (4) of the flotation cell is designed with an aeration stirring interface (10), which can be assembled with an aeration stirring head (16) and an aeration stirring pump (17), and can also be sealed with a bottom plate plug (18). All holes on the side plates of the flotation cell can be sealed tightly with side plate plugs (6).

[0005] All slurry discharge holes (7), multi-functional connection holes (8), and liquid discharge holes (9) are uniformly circular in shape and have a uniform diameter, and cannot exceed one-seventh of the height of the flotation cell.

[0006] The joint (5) in the middle of the flotation cell is about 20-30 mm higher than the bottom plate of the flotation cell than the assembled aeration stirring head (16).

[0007] The discharge holes (7) on the right side plate (1) of the flotation cell are symmetrically distributed on the plate. There are two pairs of discharge holes (7) below the joint (5) and one pair of discharge holes (7) above the joint (5). The distance between the discharge holes (7) is 3 to 4 times the diameter of the hole. The distance between the discharge hole (7) and the nearest side plate edge is 1 to 1.25 times the diameter of the discharge hole (7).

[0008] The rear side plate (2) of the flotation cell has three pairs of multi-functional connectors (8). The three pairs of connectors are symmetrically positioned. Two pairs of connectors are 0.5 to 0.75 times the diameter of the multi-functional connector (8) from the bottom plate, and the remaining pair of connectors is 0.5 to 0.6 times the diameter of the multi-functional connector (8) above the two pairs of connectors. The projections of the three pairs of multi-functional connectors (8) on the front side plate of the flotation cell do not overlap with the assembled aeration stirring head.

[0009] The drain holes (9) on the left side plate (3) of the flotation cell are arranged in the middle of the left side plate (3) of the flotation cell. Each drain hole (9) is arranged vertically at equal intervals, with a spacing of 0.1 to 0.125 times the height of the flotation cell.

[0010] The air-filled stirring interface (10) on the bottom plate (4) of the flotation cell can be seamlessly connected to the column of the air-filled stirring head (16). After the air-filled stirring head (16) and the air-filled stirring pump (17) are assembled in the flotation cell, the air-filled stirring pump (17) can fully bear the mass of the flotation cell during operation and fix the flotation cell as the base of the flotation cell.

[0011] The diameter of the cylinder of the aeration stirring interface (10) and the aeration stirring head (16) must be 10-12 mm smaller than the distance between the pair of multi-functional connectors (8) with the shortest symmetrical spacing. The frustum part of the aeration stirring head (16) is 10-12 mm higher than the multi-functional connector (8) farthest from the bottom plate (4) of the flotation cell.

[0012] When using the multi-hole rod aeration device (12), the four aeration rod interfaces need to be assembled on the four multi-functional holes (8) at the same height as the bottom plate (4) of the flotation cell.

[0013] The exhaust and stirring functions of the air-filled stirring head (16) are designed at the bottom of the truncated cone, and the exhaust flow rate and stirring intensity can be controlled by the air-filled stirring pump (17).

[0014] The length of the air bar in the multi-hole rod-type air-filling device (12) is about 0.75 to 0.85 times the shortest side length of the flotation cell, and the air bar is designed with a certain number of vent holes of 1 to 1.5 mm.

[0015] The flotation cell plate, side plate plug (6) and bottom plate plug (18) are all made of transparent hard plastic.

[0016] The parts of the external assembly equipment that enter the flotation cell and those that come into contact with the flotation cell are made of corrosion-resistant metal materials.

[0017] By adopting the above solution, the beneficial effects of this utility model are: During flotation, the aeration and stirring device is installed at the bottom of the flotation cell, which reduces the space occupied by the aeration and stirring equipment inside the flotation cell. This greatly increases the probability of the flotation pulp and air bubbles adhering to each other, and the flotation effect is improved compared to conventional flotation equipment.

[0018] The flotation cell is designed with a drain hole, which allows the liquid slurry to be directly discharged when draining the upper layer of clear liquid. When the slurry settles at the bottom, the connected upper and lower flotation cells can be disassembled, and the aeration stirring head and aeration pump inside the flotation cell can be disassembled to clean the flotation cell directly.

[0019] All components of the flotation unit can be directly disassembled and cleaned, which can effectively reduce the residual slurry in the dead corners of the unit and avoid affecting the next flotation test and subsequent maintenance of the flotation unit.

[0020] The flotation unit is highly removable, so component failures have a relatively small impact on the overall system.

[0021] This flotation unit can conduct microbubble cavitation flotation tests, and the adhesion time and flotation effect between the slurry and the foam can be changed by adjusting the position of the inlet. Attached Figure Description
