Description

Technical Field

[0001] This utility model belongs to the technical field of mineral processing equipment, and in particular relates to a mineral processing device for improving the recovery rate of mineral processing. Background Technology

[0002] Mineral processing equipment is a key core piece of equipment in the chain of mineral resource development and utilization. Its core function is to classify, sort and purify the mined raw ore through physical, chemical or physicochemical methods, so as to achieve efficient separation of useful minerals from useless minerals. This directly determines the resource utilization rate, product quality and economic benefits of mine production.

[0003] In actual use, existing mineral processing equipment easily generates a large amount of dust during the feeding and screening process of ore. Dust pollutes the working environment, endangers the health of operators, and can also cause some fine-grained useful minerals to be lost with the dust diffusion, reducing the mineral processing recovery rate. In addition, the screen plates are mostly fixed to the screening frame by bolts and other fasteners. After long-term exposure to the impact and friction of ore, the screen plates are prone to wear and deformation of the aperture, requiring regular replacement to ensure screening accuracy. Replacement requires the use of tools to disassemble the fasteners one by one, which is cumbersome, time-consuming and labor-intensive, resulting in long equipment downtime and affecting production efficiency.

[0004] Therefore, we propose a mineral processing device to improve the recovery rate of mineral processing and solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art, such as the generation of a large amount of dust during the feeding and screening process and the fact that the screen plates are mostly fixed to the screening frame by bolts and other fasteners. Therefore, this invention proposes a mineral processing device to improve the recovery rate of mineral processing in mines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mineral processing device for improving the recovery rate of mineral processing includes a shell. A material discharge trough is formed on the left side of the shell. A feed pipe is fixedly connected to the upper surface of the shell. Two auxiliary blocks are slidably connected inside the shell.

A return spring is fixedly connected to the inner wall of each limit rod. The bottom end of each return spring is connected to the auxiliary block. The inner bottom wall of the block is fixedly connected, and the inside of the guide frame is provided with a screen plate body. The left and right sides of the screen plate body are fixedly connected with fixing blocks. Each fixing block and the inside of the guide frame are fixedly connected with fixing bolts. The upper surface of the outer shell is fixedly connected with a collection box. The upper surface of the collection box is fixedly connected with two dust suction pipes. The two dust suction pipes are close to each other and penetrate the outer shell and extend into the interior of the outer shell. The inside of the collection box is slidably connected with a dust frame. The inside of the dust frame is snapped with a filter plate. The right side of the collection box is fixedly connected to a negative pressure pump.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 A mineral processing device for improving the recovery rate of mineral processing includes a shell 1. A material discharge chute 2 is provided on the left side of the shell 1. A feed pipe 3 is fixedly connected to the upper surface of the shell 1. A support frame 16 is fixedly connected to the right side of the shell 1. A conveyor belt 17 is fixedly connected to the inside of the shell 1 and the support frame 16. The support frame 16 on the right side of the shell 1 provides stable support for the conveyor belt 17, so that the conveyor belt 17 can be firmly installed on the shell 1. Its core function is to quickly transport the ore that has been screened in the shell 1 to the next process, avoid the ore from accumulating at the bottom of the shell 1, and ensure the continuity of the mineral processing process.

[0019] The inner surface of the outer shell 1 has two auxiliary blocks 4 that are slidably connected. The two auxiliary blocks 4 are equipped with a guide frame 5. The left end of the guide frame 5 passes through the discharge trough 2 and extends to the left side of the outer shell 1. Four damping buffers 18 are fixedly connected to the opposite sides of the two auxiliary blocks 4. The opposite ends of the two sets of damping buffers 18 are fixedly connected to the inner wall of the outer shell 1. There are a total of eight damping buffers 18 on the outer sides of the two auxiliary blocks 4, which are fixed to the inner wall of the outer shell 1. This can buffer the left and right swaying and impact force generated by the guide frame 5 under the action of the vibration motor 21, reduce the collision and wear between the auxiliary blocks 4 and the inner wall of the outer shell 1, reduce the noise of the equipment during operation, and maintain the stability of the guide frame 5 during the screening process.

[0020] Each auxiliary block 4 has a sliding limit rod 6 inside, the top of each limit rod 6 extends into the interior of the guide frame 5, and a return spring 7 is fixedly connected to the inner wall of each limit rod 6. The bottom end of each return spring 7 is fixedly connected to the inner bottom wall of the auxiliary block 4. A baffle 19 is fixedly connected to the bottom end of each limit rod 6, and an auxiliary handle 20 is fixedly connected to the bottom surface of each baffle 19. The baffle 19 at the bottom end of the limit rod 6 can prevent the limit rod 6 from sliding excessively upward under the action of the return spring 7 and detaching from the auxiliary block 4, thus playing a limiting role. The auxiliary handle 20 at the bottom of the baffle 19 provides a force point for the operator to manually pull the limit rod 6 to quickly release the fixation of the guide frame 5, which facilitates the removal and maintenance of the guide frame 5.

[0021] The guide frame 5 is equipped with a screen plate body 8 inside, and the outer shell 1 is equipped with a vibration motor 21 inside. The outer surface of the vibration motor 21 is fixedly connected to the bottom surface of the guide frame 5, and the vibration motor 21 inside the outer shell 1 is fixed to the bottom surface of the guide frame 5. The vibration force generated during operation is directly transmitted to the guide frame 5, which drives the screen plate body 8 to vibrate synchronously. This can accelerate the separation of ore on the screen plate body 8, allowing ore that meets the particle size requirements to be screened off quickly, improving screening efficiency, and reducing clogging of ore on the surface of the screen plate body 8.

[0022] Fixing blocks 9 are fixedly connected to both the left and right sides of the screen plate body 8. Each fixing block 9 and the guide frame 5 are fixedly connected to a fixing bolt 10. A collection box 11 is fixedly connected to the upper surface of the outer shell 1. A pull handle 23 is fixedly connected to the left side of the collection box 11. An anti-slip sleeve 24 is fixedly connected to the outer surface of the pull handle 23. The pull handle 23 on the left side of the collection box 11 provides a convenient force point for moving the collection box 11, which facilitates the overall handling and position adjustment of the equipment. The anti-slip sleeve 24 on the outer surface of the pull handle 23 increases the friction between the hand and the handle, prevents slippage when pulling, and improves the safety and convenience of operation.

[0023] Two suction pipes 12 are fixedly connected to the upper surface of the collection box 11. The ends of the two suction pipes 12 that are close to each other pass through the outer shell 1 and extend into the interior of the outer shell 1. A dust frame 13 is slidably connected inside the collection box 11. A sliding block 22 is fixedly connected to the bottom surface of the dust frame 13. The sliding block 22 is slidably connected inside the collection box 11. The sliding block 22 on the bottom surface of the dust frame 13 is slidably connected inside the collection box 11, which transforms the sliding friction between the dust frame 13 and the collection box 11 into smoother rolling friction, so that the operator can easily pull out or push in the dust frame 13 and conveniently complete the dust cleaning and filter plate 14 replacement and maintenance work.

[0024] A filter plate 14 is snapped into the inside of the dust frame 13. A negative pressure pump 15 is fixedly connected to the right side of the collection box 11. A reinforcing block 25 is fixedly connected to the outer surface of the negative pressure pump 15. The left side of the reinforcing block 25 is fixedly connected to the right side of the collection box 11. The reinforcing block 25 on the outer surface of the negative pressure pump 15 firmly fixes the negative pressure pump 15 to the right side of the collection box 11, enhancing the installation firmness of the negative pressure pump 15 and preventing the negative pressure pump 15 from loosening or shifting due to vibration when running at high speed. This ensures the stable operation of the negative pressure dust collection system and prevents the dust collection effect from decreasing due to the displacement of the negative pressure pump 15.

[0025] The working principle of this utility model is as follows: During use, the ore to be screened is fed into the device through the feed pipe 3, which is fixedly connected to the upper surface of the outer shell 1. The ore falls directly onto the screen plate body 8 inside the guide frame 5 along the feed pipe 3. At this time, the conveyor belt 17 starts, ready to receive the screened ore. The vibration motor 21 inside the outer shell 1 is then started. The vibration force generated by the vibration motor 21 is transmitted to the guide frame 5, causing the screen plate body 8 to vibrate at high frequency. Under the action of vibration, the portion of the ore that meets the particle size requirements quickly passes through the screen holes of the screen plate body 8 and falls onto the conveyor belt below. On the conveyor belt 17, the ore is conveyed to the subsequent process. Ore that does not meet the particle size requirements remains on the screen plate body 8 and moves to the left as the guide frame 5 vibrates, eventually being discharged through the discharge chute 2 on the left side of the outer shell 1, completing the preliminary screening. During this process, the damping buffers 18 on both sides of the auxiliary block 4 continuously buffer the vibration impact force of the guide frame 5 to maintain screening stability. Simultaneously, the negative pressure pump 15 on the right side of the collection box 11 is started. The operation of the negative pressure pump 15 creates a negative pressure environment inside the collection box 11. Dust generated during mineral processing and screening is discharged under the action of negative pressure. Dust is drawn into the collection box 11 through two suction pipes 12 on the lower surface of the collection box 11. After entering the collection box 11, the dust is filtered by the filter plate 14 inside the dust frame 13 and is trapped in the dust frame 13. Clean air is discharged through the negative pressure pump 15 to prevent dust from spreading and causing mineral loss and environmental pollution. At the same time, the reinforcing block 25 on the outer surface of the negative pressure pump 15 ensures its stable operation and prevents vibration and displacement. When the screen plate body 8 is worn or the aperture is deformed and needs to be replaced, the operator pulls the baffle 19 through the auxiliary handle 20, which drives the limit rod 6 to move towards Slide down and compress the return spring 7 to disengage the top of the limit rod 6 from the guide frame 5, releasing the fixation of the guide frame 5. Then the guide frame 5 can be pulled out of the outer shell 1 through the material leakage trough 2. Unscrew the fixing block 9 and the fixing bolt 10 on the guide frame 5 to replace the new screen plate body 8. When there is a lot of dust accumulation in the dust frame 13, the dust frame 13 can be easily pulled out of the collection box 11 by pulling the handle 23 in conjunction with the sliding block 22 at the bottom of the dust frame 13. After cleaning the internal dust, push the dust frame 13 back to its original position. After the maintenance is completed, the equipment can be put back into use.
