Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.
[0022] Embodiment one, please refer to Figure 1 Figure 6 The present application is a mobile spiral chute ore dressing device, which comprises a vehicle frame 13, a shock absorber 14 fixedly connected to the bottom of the vehicle frame 13, four wheels 15 rotatably connected to the outer wall of the shock absorber 14, a fixing frame 16 fixedly connected to the top of the vehicle frame 13, and further comprising: a fixing mechanism 1 fixedly connected to the inner wall of the fixing frame 16, through which the ore pulp enters the inside of the separation process; a deposition mechanism 2 fixedly connected to the inner wall of the fixing mechanism 1, at which the ore pulp is separated to complete the ore dressing process; an outflow mechanism 3 fixedly connected to the inner wall of the deposition mechanism 2, which collects the ore pulp outside the deposition mechanism 2 and impacts the metal particles deposited inside; Wherein, when the device is in use, the pipelines inside the fixing mechanism 1 are connected to each other to ensure that the ore pulp can be transmitted to the inside of the deposition mechanism 2 through the fixing mechanism 1, and the separation of the ore pulp is completed with the assistance of the outflow mechanism 3.
[0023] The fixing mechanism 1 comprises: a storage assembly 11 fixedly connected to the top of the fixing frame 16; a feeding assembly 12 fixedly connected to the inner wall of the fixing frame 16; Wherein, before use, the pipelines of the storage assembly 11 and the feeding assembly 12 are connected, and the staff connects the external pipeline with the storage assembly 11 to ensure that the ore pulp enters the inside of the storage assembly 11 through the external pipeline.
[0024] The deposition mechanism 2 comprises: a shunt assembly 21 fixedly connected to the outer wall of the storage assembly 11; a trapping assembly 22 fixedly connected to the outer wall of the shunt assembly 21; Wherein, when the ore pulp is sprayed from the feeding assembly 12, it will flow downward along the outer wall of the shunt assembly 21 to complete the basic ore dressing process, and the trapping assembly 22 will intercept the metal particles inside the ore pulp.
[0025] The outflow mechanism 3 comprises: The auxiliary assembly 31 is fixedly connected to the inner wall of the trapping assembly 22. The auxiliary assembly 31 guides the metal particles accumulated in the trapping assembly 22 to flow outwards and close to the center position.
[0026] In the second embodiment, please refer to Figure 3 - Figure 8 The storage assembly 11 includes a support frame 111 fixedly connected to the inner wall of the fixed frame 16, and a slurry tank 112 fixedly connected to the top of the support frame 111. The bottom of the slurry tank 112 is connected with a plurality of water outlet pipes, and the slurry in the slurry tank 112 can flow outwards through the water outlet pipes when the slurry enters the slurry tank 112 through the feeding tank 113.
[0027] The feeding assembly 12 includes a limiting frame 121 fixedly connected to the inner wall of the fixed frame 16, a center rod 122 fixedly connected to the inner wall of the limiting frame 121, and an output pipe 123 fixedly connected to the outer wall of the limiting frame 121. Before use, the output pipe 123 is connected with the water outlet pipes at the bottom of the slurry tank 112, and the slurry in the slurry tank 112 is transmitted to the top of the spiral chute 211 through the output pipe 123. Figure 4 When the slurry flows along the inner wall of the spiral chute 211, it is roughly divided into three parts: concentrate, middling, and tailings, which flow outwards from the G, H, and J positions, respectively, to complete the mineral separation process.
[0028] The shunt assembly 21 includes three spiral chutes 211 fixedly connected to the outer wall of the center rod 122, a buffer layer 212 fixedly connected to the bottom outer wall of the spiral chute 211, and a shunt plate 213 fixedly connected to the top of the buffer layer 212. When the slurry is sprayed outwards through the output pipe 123, it contacts the top of the spiral chute 211 and flows along the inner wall of the spiral chute 211 for separation.
[0029] The trapping assembly 22 includes an inclined groove 221 opened in the outer wall of the spiral chute 211, a fixed plate 222 fixedly connected to the inner wall of the inclined groove 221, and a flow barrier plate 223 fixedly connected to the inner wall of the fixed plate 222. Each fixed plate 222 is designed at a right angle between them, as shown in Figure 4As shown, after mineral processing, the metal particles and slurry in the upper fixed plate 222 flow downwards along path M. At this time, the lighter impurities in the slurry will flow outwards along path N and re-enter the interior of the next fixed plate 222 for further separation. The heavy metals along path M will pass through the outlet end of the fixed plate 222. The heavy metals along path M and path U impact each other, slowing down the flow speed of the concentrate on the inner wall of the spiral chute 211. Through the application of the above components, it is effectively prevented that the concentrate falls too fast and mixes with the middlings due to its excessive potential energy.
[0030] The auxiliary component 31 includes an inner groove 311 formed in the side wall of the fixing plate 222, and a slope block 312 is fixedly connected to the inner wall of the end of the fixing plate 222 near the center rod 122. As the slurry flows along the inner wall of the spiral chute 211, it will... Figure 7 The slurry flows along the Y-path. Heavier metal particles in the slurry, due to their weight, will enter the fixed plate 222 via Z and X paths as they pass the top of the fixed plate 222, and briefly accumulate inside the inner groove 311. Furthermore, the fixed plate 222 has an inclined design on the outer wall of the spiral chute 211, allowing the slurry to flow along the Y-path. Figure 4 When the slurry flows along path B, the impact force generated when the slurry enters the inclined block 312 will force the metal particles inside the groove 311 to move along path U to the spiral chute 211 near the central rod 122. Through the application of the above components, the beneficiation efficiency of the spiral chute 211 is effectively improved, making it suitable for beneficiation of short-distance spiral chute 211.
[0031] The side wall of the inclined block 312 is fixedly connected to the outer wall of the spiral chute 211, and the end of the baffle plate 223 near the center rod 122 is fixedly connected to the outer wall of the inclined block 312. Specifically, by utilizing the characteristic of the aforementioned metal particles accumulating inside the inner groove 311, the metal particles can be... Figure 7 The inner groove 311 is traversed by two paths, Z and X. Since Z is located upstream, more metal particles flow through the Z path. After passing through this location, the slurry will experience a small eddy. When the slurry carrying the eddy passes through the X location, it will disturb the metal particles inside the inner groove 311, causing the precipitated metal particles to change from a completely precipitated state to a flowing state. Through the application of the above components, the complete precipitation of metal particles inside the inner groove 311 is effectively prevented, thus avoiding the phenomenon of filling the inner groove 311 and affecting the beneficiation efficiency.
[0032] A specific application of this embodiment is as follows: Before using the equipment, connect the output pipe 123 to the bottom outlet pipe of the slurry tank 112, and ensure that the slurry inside the slurry tank 112 is transferred to the top of the spiral chute 211 through the output pipe 123. When the slurry flows along the inner wall of the spiral chute 211, the slurry will be roughly divided into three parts: concentrate, middlings, and tailings, which are respectively discharged from... Figure 4 The minerals flow outwards from positions G, H, and J, completing the mineral processing step. To address the issue of the short spiral chute 211, a retaining component 22 is installed inside the equipment. When the slurry flows along the inner wall of the spiral chute 211, it will be retained at a certain angle. Figure 7 The slurry flows along the Y-path. Heavier metal particles in the slurry, due to their weight, will enter the fixed plate 222 via Z and X paths as they pass the top of the fixed plate 222, and briefly accumulate inside the inner groove 311. Furthermore, the fixed plate 222 has an inclined design on the outer wall of the spiral chute 211, allowing the slurry to flow along the Y-path. Figure 4 When the slurry flows along path B, the impact force generated when the slurry enters the inclined block 312 will force the metal particles inside the groove 311 to move along path U to the spiral chute 211 near the central rod 122. Through the application of the above components, the beneficiation efficiency of the spiral chute 211 is effectively improved, making it suitable for beneficiation of short-distance spiral chute 211.
[0033] Utilizing the aforementioned characteristic of metal particles accumulating inside the inner groove 311, the metal particles can be... Figure 7 The inner groove 311 is traversed by two paths, Z and X. Since Z is located upstream, more metal particles flow through the Z path. After passing through this location, the slurry will experience a small eddy. When the slurry carrying the eddy passes through the X location, it will disturb the metal particles inside the inner groove 311, causing the precipitated metal particles to change from a completely precipitated state to a flowing state. Through the application of the above components, the complete precipitation of metal particles inside the inner groove 311 is effectively prevented, thus avoiding the phenomenon of filling the inner groove 311 and affecting the beneficiation efficiency.
[0034] Taking advantage of the characteristic of the particles flowing along the U-path, each fixed plate 222 is designed to be at a right angle, such as... Figure 4 As shown, after mineral processing, the metal particles and slurry in the upper fixed plate 222 flow downwards along path M. At this time, the lighter impurities in the slurry will flow outwards along path N and re-enter the interior of the next fixed plate 222 for further separation. The heavy metals along path M will pass through the outlet end of the fixed plate 222. The heavy metals along path M and path U impact each other, slowing down the flow speed of the concentrate on the inner wall of the spiral chute 211. Through the application of the above components, it is effectively prevented that the concentrate falls too fast and mixes with the middlings due to its excessive potential energy.
[0035] In order to prevent the metal particles from being blocked in the inner groove 311, the fixed plate 222 is designed to be narrow at the outer end and wide at the inner end. When the metal particles flow along the inner wall of the inner groove 311, the flow cross section is enlarged from the narrow end to the wide end, so that the speed of the metal particles is slowed down, preventing the metal particles from being impacted on the inner wall of the spiral chute 211 at a high speed, and preventing the metal particles from being diffused to the surroundings under a large resistance and combined with the middlings.

The preferred embodiments do not describe all the details and limit the present application to the specific embodiments. Obviously, many modifications and variations can be made according to the content of the present application.
