Description

Technical Field

[0001] This invention relates to the field of mineral processing equipment technology, specifically to a mineral processing flotation equipment using a rubber-steel composite impact-resistant and wear-resistant trough. Background Technology

[0002] Flotation machines are one of the core pieces of equipment in the mineral processing flow of mines. The inner wall of the tank and its supporting components are subjected to continuous scouring and wear of the ore-bearing slurry driven by the high-speed rotating impeller. The wear resistance, maintainability and flotation efficiency of the equipment directly affect the production efficiency and operating costs of the mine.

[0003] Existing flotation cell protection technology has the following prominent drawbacks:

[0004] Firstly, traditional flotation machines lack a tank protection mechanism. The frame is made of steel angle iron and directly welded to the inner wall of the tank. When the impeller rotates at high speed, the slurry particles cause wear on both the frame and the tank. Because the metal surface is in direct contact with the high-hardness slurry particles, the wear resistance is insufficient, and the service life is generally only one to three months. The number of annual maintenance is high, the equipment production continuity is poor, and the overall operating cost is high.

[0005] Secondly, traditional welded connection structures require replacement after the protective plate is damaged, which is time-consuming and labor-intensive, and hot work poses safety hazards; the downtime during maintenance is long, which seriously affects the execution of the mine's production plan.

[0006] Third, wear and tear in high-wear areas of the tank can easily lead to slurry leakage, which not only wastes mineral resources but also pollutes the production site environment, resulting in high cleanup costs.

[0007] Fourth, traditional flotation machines typically rely solely on air guidance at the center of the impeller to generate bubbles. The bubble generation area is concentrated near the impeller, while the bubble distribution on the side wall of the tank is sparse. This results in insufficient gas-solid contact throughout the slurry, which restricts further improvement in flotation recovery rate.

[0008] In summary, existing flotation tank protection equipment has significant shortcomings in terms of wear resistance, ease of maintenance, and flotation enhancement. There is an urgent need for a new type of tank protection equipment that can combine excellent wear resistance, quick disassembly and replacement, and auxiliary flotation enhancement functions. Summary of the Invention

[0009] The purpose of this invention is to provide a rubber-steel composite impact-resistant and wear-resistant trough protection device for mineral processing flotation.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a rubber-steel composite impact-resistant and wear-resistant trough device for mineral processing flotation, comprising a wear-resistant trough device body, an inner wall of the wear-resistant trough device body having a placement groove, a positioning rod fixedly connected to the inner wall of the placement groove, a wear-resistant protective plate being disposed in the placement groove, a positioning groove adapted to the shape of the positioning rod being formed on the side of the wear-resistant protective plate facing the inner wall of the placement groove, a placement hole being formed in the groove wall of the wear-resistant trough device body, a connecting pipe being disposed on the inner wall of the placement hole, one end of the connecting pipe extending to the inner wall of the wear-resistant protective plate, the wear-resistant protective plate being away from the positioning groove.

[0011] As a further aspect of the present invention: the wear-resistant protective plate includes a steel plate layer and a wear-resistant rubber layer fixed to the side of the steel plate layer facing the inner cavity of the tank. The wear-resistant rubber layer and the steel plate layer form a chemically bonded composite through a vulcanization process. The wear-resistant rubber layer is disposed facing the inner cavity of the wear-resistant tank protection equipment body, and the steel plate layer is disposed against the inner wall of the wear-resistant tank protection equipment body. The thickness of the wear-resistant rubber layer is greater than the thickness of the steel plate layer.

[0012] As a further aspect of the present invention: a support frame is detachably connected to the top of the wear-resistant groove protection device body, a servo motor is fixedly connected to the top surface of the support frame, an impeller is fixedly connected to the output end of the servo motor, and a sleeve is fixedly connected to the bottom of the support frame, the sleeve being sleeved on the drive shaft of the output end of the servo motor.

[0013] As a further embodiment of the present invention: the top surface of the support frame is provided with a ventilation mechanism, the ventilation mechanism including a gas source device, a gas flow regulating valve and a ventilation pipe, the gas source device is fixedly connected to one side of the top surface of the support frame, the output end of the gas source device is fixedly connected to the top end of the ventilation pipe, the gas flow regulating valve is located in the middle of the ventilation pipe, and the bottom end of the ventilation pipe is fixedly connected to the other end of the connecting pipe.

[0014] As a further embodiment of the present invention: each end of the horizontal assembly rod is provided with a slot, and each end of the vertical assembly rod is fixedly connected with a locking block that matches the shape of the slot. The locking block is inserted into the slot to vertically engage and connect the horizontal assembly rod and the vertical assembly rod.

[0015] As a further aspect of the present invention: the air outlet is an array of through holes evenly distributed on the surface of the wear-resistant protective plate facing the inner cavity of the tank, and the inner wall of the wear-resistant protective plate is provided with a gas guiding channel that connects the connecting pipe to all the air outlets.

[0016] As a further aspect of the present invention: the gas flow regulating valve regulates the gas flow rate entering the vent pipe, and the compressed gas generated by the gas source equipment is sequentially introduced into the gas guide channel of the inner wall of the wear-resistant protective plate through the gas flow regulating valve, the vent pipe and the connecting pipe, and then released into the slurry in the inner cavity of the tank through the air outlet, where it superimposes with the bubbles generated by the impeller to form a bubble distribution field with an expanded coverage area in the inner cavity of the tank.

[0017] As a further aspect of the present invention: the number of wear-resistant protective plates is multiple, and the multiple wear-resistant protective plates are arranged sequentially end to end along the extension direction of the placement groove, covering the entire placement groove area of ​​the inner wall of the wear-resistant protective groove equipment body.

[0018] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0019] 1. This invention utilizes a rubber-steel composite structure for the wear-resistant protective plate. The wear-resistant rubber layer forms a chemically bonded composite with the steel plate layer through a vulcanization process, exhibiting excellent elastic deformation energy absorption characteristics. This effectively absorbs the impact kinetic energy of the slurry, significantly reducing the wear rate of the metal substrate. Compared with traditional all-metal trough structures, the service life of the protective plate is significantly extended, and the annual number of maintenance operations and direct maintenance costs are greatly reduced.

[0020] 2. This invention achieves rapid positioning within the groove by using a wear-resistant protective plate in conjunction with a positioning groove and a positioning rod. Then, through the coordinated action of assembly blocks, horizontal assembly rods, vertical assembly rods, limiting plates, and bolts, it achieves detachable fixation. Replacing the protective plate only requires unscrewing the bolts, eliminating the need for welding or gas cutting, thus removing fire safety hazards, making maintenance safer, and significantly reducing downtime.

[0021] 3. This invention achieves full coverage of high-wear areas on the inner wall of the tank by using a rubber-steel composite protective plate. The elastic properties of the wear-resistant rubber layer effectively prevent the slurry from eroding and penetrating, eliminating the risk of slurry leakage and avoiding waste of mineral resources and pollution of the on-site environment.

[0022] 4. This invention constructs an auxiliary gas supply link through a gas source device, a gas flow regulating valve, a vent pipe, a connecting pipe, and a gas outlet, which introduces adjustable flow compressed gas into the guard plate area. The gas outlet then releases bubbles into the slurry, which overlap with the primary bubbles generated by the impeller to form a bubble distribution field with a wider coverage area. This increases the probability of collision and contact between mineral particles and bubbles, thereby improving the flotation recovery effect.

[0023] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art based on the following examination or study, or may be taught from the practice of the invention.

[0034] Furthermore, the wear-resistant protective plate 42 includes a steel plate layer and a wear-resistant rubber layer fixed to the side of the steel plate layer facing the inner cavity of the tank. The wear-resistant rubber layer and the steel plate layer form a chemically bonded composite through a vulcanization process. The wear-resistant rubber layer is disposed facing the inner cavity of the wear-resistant tank protection equipment body 1, and the steel plate layer is disposed against the inner wall of the wear-resistant tank protection equipment body 1. The thickness of the wear-resistant rubber layer is greater than the thickness of the steel plate layer.

[0035] Furthermore, a support frame 2 is detachably connected to the top of the wear-resistant groove protection equipment body 1. A servo motor 21 is fixedly connected to the top surface of the support frame 2. An impeller 22 is fixedly connected to the output end of the servo motor 21. A sleeve 23 is fixedly connected to the bottom of the support frame 2. The sleeve 23 is sleeved on the drive shaft at the output end of the servo motor 21.

[0036] Furthermore, a ventilation mechanism 3 is provided on the top surface of the support frame 2.

[0039] The whole system consists of five parts: the wear-resistant trough protection equipment body 1, the support frame 2, the ventilation mechanism 3, the wear-resistant mechanism 4, and the grid frame assembly 5.

[0040] I. Structure and Installation of Wear-Resistant Guard Plates

[0041] The inner wall of the wear-resistant protective trough equipment body 1 is provided with a placement groove along its circumferential bottom. Multiple positioning rods 41 are fixedly connected to the inner wall of the placement groove along its extension direction. The wear-resistant protective plate 42 slides in along the guide direction of the placement groove. A positioning groove 44 is provided on the side of the wear-resistant protective plate 42 facing the inner wall of the placement groove, corresponding to the position of the positioning rod 41. The shape of the positioning groove 44 is adapted to the cross-sectional shape of the positioning rod 41. After the wear-resistant protective plate 42 is embedded in the placement groove, the positioning rod 41 is engaged in the positioning groove 44, realizing the accurate positioning of the wear-resistant protective plate 42 on the inner wall of the trough and preventing the protective plate from lateral displacement during equipment operation.

[0042] The wear-resistant guard plate 42 is a rubber-steel composite structure, consisting of a steel plate layer and a wear-resistant rubber layer fixed to the side of the steel plate layer facing the inner cavity of the tank. The wear-resistant rubber layer and the steel plate layer are formed into an inseparable chemically bonded composite through a vulcanization process, which has good integrity and impact resistance. During installation, the wear-resistant rubber layer faces the inner cavity of the tank and directly bears the impact of the slurry; the steel plate layer is attached to the inner wall of the wear-resistant tank protection equipment body 1 to provide rigid support. The thickness of the wear-resistant rubber layer is greater than the thickness of the steel plate layer, so that the wear-resistant guard plate 42 as a whole has sufficient elastic energy absorption and wear reduction function.

[0043] Multiple wear-resistant protective plates 42 are spliced ​​end to end along the extension direction of the placement groove, fully covering all high-wear areas of the inner wall of the wear-resistant protective groove equipment body 1.

[0044] II. Auxiliary Gas Supply System

[0045] The tank wall of the wear-resistant protective tank equipment body 1 is provided with placement holes 45 corresponding to each area of ​​the wear-resistant protective plate 42. A connecting pipe 46 is provided on the inner wall of the placement hole 45. One end of the connecting pipe 46 extends to the inner wall of the wear-resistant protective plate 42 and communicates with the gas guide channel inside the protective plate. The other end passes through the tank wall and is fixedly connected to the bottom end of the ventilation pipe 33.

[0046] On the side of the wear-resistant protective plate 42 away from the positioning groove 44, that is, on the surface of the wear-resistant rubber layer facing the inner cavity of the groove, there is an air outlet 43. The air outlet 43 is a uniformly distributed array of through holes, which are connected to the connecting pipe 46 through the gas guide channel on the inner wall of the wear-resistant protective plate 42, so that the compressed gas can be evenly dispersed and released into the slurry.

[0047] A gas source device 31 is fixedly connected to one side of the top surface of the support frame 2. The output end of the gas source device 31 is fixedly connected to the top end of the air pipe 33. A gas flow regulating valve 32 is provided in the middle of the air pipe 33 to regulate the gas flow rate entering the inner cavity of the tank. The bottom end of the air pipe 33 is fixedly connected to the gas guide channel on the inner wall of the wear-resistant protective plate 42 through the connecting pipe 46.

[0048] During operation, the compressed gas generated by the gas source device 31 is regulated by the gas flow regulating valve 32 and then enters the gas guide channel on the inner wall of the wear-resistant guard plate 42 through the air pipe 33 and the connecting pipe 46. It is then evenly released into the slurry in the inner cavity of the tank through the air outlet 43, forming an auxiliary bubble group. This group overlaps with the primary bubbles generated by the impeller 22, expanding the bubble coverage area in the tank, increasing the probability of collision and contact between mineral particles and bubbles, and improving the flotation recovery effect.

[0049] III. Support Frame and Transmission System

[0050] The top of the wear-resistant trough protector body 1 is detachably connected to a support frame 2. The support frame 2 is fixed to the top of the trough body with bolts for easy overall maintenance. A servo motor 21 is fixedly connected to the middle of the top surface of the support frame 2. An impeller 22 is fixedly connected to the output end of the servo motor 21. The impeller 22 extends downward into the inner cavity of the wear-resistant trough protector body 1. Through high-speed rotation, the mineral particles in the slurry are fully suspended and dispersed. At the same time, the gas introduced from the center is sheared and dispersed to form primary bubbles. A sleeve 23 is fixedly connected to the bottom of the support frame 2. The sleeve 23 is sleeved on the drive shaft at the output end of the servo motor 21. It guides and protects the drive shaft to prevent the slurry from entering the sealing area of ​​the drive shaft.

[0051] IV. Structure and Assembly of the Drill Frame Components

[0052] The wear-resistant protective plate 42 is fixedly connected to the assembly block 51 on the side facing the opening of the placement slot. The grid frame assembly 5 includes a horizontal assembly rod 53 and a vertical assembly rod 54. The horizontal assembly rod 53 and the vertical assembly rod 54 intersect perpendicularly to form a grid-shaped frame structure.

[0053] Each end of the horizontal assembly rod 53 has a slot, and each end of the vertical assembly rod 54 is fixedly connected to a locking block 55 that matches the shape of the slot. The locking block 55 is inserted into the slot to achieve vertical engagement between the horizontal assembly rod 53 and the vertical assembly rod 54, locking the two into a stable grid-shaped frame, providing overall reliable support for the wear-resistant protective plate 42.

[0054] The vertical assembly rod 54 has an assembly groove 52 on its side that matches the shape of the assembly block 51. During installation, the assembly block 51 is embedded in the assembly groove 52 to achieve directional installation of the wear-resistant guard plate 42 on the grid frame. The bottom surface of the horizontal assembly rod 53 is fixedly connected to a limiting plate 56 along its length. The limiting plate 56 and the bottom surface of the horizontal assembly rod 53 together form a spatial channel that restricts the assembly block 51. The assembly block 51 has a screw hole 57 that extends to the inner wall of the limiting plate 56. The bolt is threaded into the screw hole 57. By tightening the bolt, the assembly block 51 is pressed and locked between the horizontal assembly rod 53 and the limiting plate 56, thus achieving the detachable fixing of the wear-resistant guard plate 42.

[0055] When replacing the damaged wear-resistant plate 42, simply unscrew the corresponding bolts to remove the assembly block 51 from the assembly slot 52, and then remove the plate. No welding or gas cutting is required throughout the process, significantly shortening the replacement time for a single plate and greatly improving maintenance efficiency.
