Description

Technical Field

[0001] This utility model relates to the field of ore feeder technology, specifically to a feeder for a spiral concentrator. Background Technology

[0002] In the field of mineral processing, spiral concentrators are widely used for gravity separation of metals and non-metals such as iron, manganese, and tin due to their simple structure, high separation efficiency, and low cost. The feeder, as its core feeding component, needs to accurately and evenly deliver the slurry (a mixture of slurry and water) to the spiral plate to form a stable flow layer to achieve mineral separation. Its performance directly determines the separation accuracy, throughput, and reliability of the spiral concentrator.

[0003] However, existing spiral concentrator feeders have significant technical defects and are unable to meet production requirements. The specific problems are as follows: 1. Uneven distribution of ore liquid: Most of them are single cavity or simple baffle structure. The ore liquid is prone to "biased flow" and "mixed flow" due to the turbulent flow field and poor sealing of the baffle. This leads to the imbalance of ore liquid volume in each spiral plate and large differences in flow rate / thickness, which reduces the recovery rate and grade of the target mineral and causes resource waste.

[0004] 2. The injection pipeline is prone to displacement: The pipeline is mostly "directly inserted" without a positioning and fixing structure. The impact of the ore liquid can easily cause the pipeline to swing and deviate, which will aggravate the imbalance of ore liquid distribution, increase the wear of the pipeline and the feed port, and increase the maintenance cost. 3. Low ore flow efficiency: The bottom of the inner cavity is mostly flat, and the ore liquid is prone to forming "stagnant zones" or even sedimentation, resulting in low ore feeding efficiency, which cannot meet the demand for high processing volume, and is also prone to clogging the channel and reducing operational stability.

[0005] In summary, to address the shortcomings of existing feeders in terms of ore liquid diversion, pipeline fixation, and feeding efficiency, a feeder for a spiral concentrator is provided. Utility Model Content

[0006] The purpose of this invention is to provide a feeder for a spiral concentrator to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A feeder for a spiral concentrator includes a diverter cylinder. At least three support frames are fixedly installed circumferentially and at equal intervals on the outer surface of the diverter cylinder. Three discharge ports are opened through the diverter cylinder, and discharge pipes are fixedly installed at each discharge port on the outer surface of the diverter cylinder. Three V-shaped sealing baffles are fixedly installed circumferentially and at equal intervals inside the diverter cylinder. A slurry channel is formed between two adjacent V-shaped sealing baffles, and the position of the slurry channel corresponds to that of the discharge port.

[0008] Preferably, a connecting pipe is fixedly installed between the three V-shaped sealing partitions, and the outer surface of the connecting pipe has three outlets that are circumferentially equidistantly opened, and the outlets correspond one-to-one with the positions of the mining channel.

[0009] Preferably, a flange is fixedly installed on the upper surface of the connecting pipe.

[0010] Preferably, a conical support plate is fixedly installed at the bottom of the inner cavity of the diverter, and the upper surface of the conical support plate is in contact with the lower surface of the connecting pipe and the V-shaped sealing partition.

[0011] Preferably, the end of the support frame away from the diverter cylinder is L-shaped, and the upper surface of the L-shaped end is provided with mounting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes three circumferentially equidistant V-shaped sealing baffles to form three independent and sealed ore liquid channels within the diversion cylinder. Combined with corresponding discharge ports and pipes, the ore liquid injected from the vertical central axis of the diversion cylinder can be precisely and uniformly guided to different preset areas of the same spiral plate. This ensures that the ore liquid forms a uniformly thick and stable flow layer on the surface of the same spiral plate, avoiding differences in separation time caused by localized ore liquid accumulation or gaps. This improves the separation accuracy, recovery rate, and grade of target minerals on the same spiral plate, while reducing the waste of valuable minerals in tailings.

[0013] By installing a connecting pipe between the V-shaped sealing baffles, the slurry injection pipe can be inserted into the connecting pipe for positioning and fixation. This avoids the axial swing or radial displacement of the pipe caused by the impact and fluctuation of the slurry in the existing "direct insertion" structure, ensuring that the slurry injection port is always aligned with the preset feed center of the distribution cylinder, providing a stable premise for the uniform distribution of the slurry to the same spiral plate. At the same time, the cooperation between the pipe and the connecting pipe can reduce the direct wear between the pipe and the feeder inlet, extend the service life of components, and reduce the maintenance frequency and cost caused by pipe misalignment and wear.

[0014] By fixing a conical support plate at the bottom of the inner cavity of the diverter, with its inclined surface fitting against the lower surface of the connecting pipe and the V-shaped sealing baffle, the inclined structure can quickly guide the slurry to each discharge port and then simultaneously convey it to the same spiral plate. This effectively solves the problem of the "stagnation zone" of slurry at the bottom of the existing flat plate, and avoids slurry deposition under low flow rate conditions that could lead to untimely feeding of the same spiral plate. This not only improves the feeding efficiency of the feeder, ensuring a consistently sufficient and uniform supply of slurry to the same spiral plate to meet high-volume beneficiation requirements, but also prevents slurry deposition that could clog the discharge ports, reducing downtime caused by cleaning blockages and further ensuring the continuous separation stability of the same spiral plate.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: A feeder for a spiral concentrator includes a diverter cylinder 1. At least three support frames 11 are circumferentially and equidistantly fixed to the outer surface of the diverter cylinder 1. The end of each support frame 11 furthest from the diverter cylinder 1 is L-shaped, and each L-shaped end has a through-hole on its upper surface. During installation and use, the feeder is combined with… Figure 4 As shown, the diverter 1 can be supported and installed above the frame 6 of the spiral concentrator by using bolts to connect the mounting holes on the support frame 11.

[0022] Combination Figure 2 As shown, three discharge ports 12 are opened through the diversion cylinder 1, and discharge pipes 2 are fixedly installed at each discharge port 12 on the outer surface of the diversion cylinder 1. Three V-shaped sealing baffles 3 are fixedly installed circumferentially and at equal intervals inside the diversion cylinder 1. The mineral liquid channel is formed between two adjacent V-shaped sealing baffles 3. The position of the mineral liquid channel corresponds to the position of the discharge port 12. After the mineral liquid is injected from the vertical central axis of the diversion cylinder 1, the mineral liquid can be accurately guided to the position of the discharge port 12 under the action of the mineral liquid channel, and finally discharged from the discharge pipe 2 and flowed into the spiral plate of the spiral concentrator.

[0023] Combination Figure 1 and Figure 2As shown, a connecting pipe 4 is fixedly installed between the three V-shaped sealing partitions 3. The outer surface of the connecting pipe 4 has three outlets 41 that are circumferentially equidistant. The outlets 41 correspond one-to-one with the positions of the mining channel. By setting the connecting pipe 4, the slurry injection pipe can be inserted into the connecting pipe 4, so as to avoid the slurry injection pipe from swinging and shifting under the fluctuation of water flow, which would affect the grouting effect.

[0024] In addition, to facilitate the connection between the metal pipe and the connecting pipe 4, combined with Figure 1 As shown, a flange 42 is fixedly installed on the upper surface of the connecting pipe 4, which can be used to connect with the metal pipe used for ore injection.

[0025] Finally, in order to accelerate the efficiency of the feed solution, combined with Figure 2 As shown, a conical support plate 5 needs to be fixedly installed at the bottom of the inner cavity of the diverter 1. The upper surface of the conical support plate 5 is in contact with the lower surface of the connecting pipe 4 and the V-shaped sealing partition 3. The inclined surface of the conical support plate 5 can be used to quickly guide the ore liquid to the discharge port 12, thereby improving the efficiency of feeding the ore liquid.

[0026] Working principle: First, the diverter 1 is stably supported and installed above the frame 6 of the spiral concentrator using L-shaped support frames 11 equidistantly arranged on the outer surface of the diverter 1, with bolts and mounting holes on the support frames 11. Next, the metal pipe for injecting ore liquid is precisely connected and fixed using the flange 42 on the upper surface of the connecting pipe 4 (if the ore liquid injection pipe is made of plastic, it is directly inserted into the connecting pipe 4) to prevent the pipe from swinging or shifting due to the impact of the ore liquid flow. Subsequently, the ore liquid is injected into the connecting pipe 4 from the vertical central axis of the diverter 1, and enters the interior of the diverter 1 through the outlets 41 on the connecting pipe 4 that correspond one-to-one with the ore liquid channels. Inside the diversion cylinder 1, three circumferentially equidistant V-shaped sealing baffles 3 form three independent sealed ore liquid channels. The ore liquid flows directionally within the channels. At the same time, the conical support plate 5 at the bottom of the inner cavity of the diversion cylinder 1 accelerates the guidance of the ore liquid through the inclined surface, so that the ore liquid passes quickly and evenly through the corresponding discharge port 12 of each channel, and is then synchronously transported through the discharge pipe 2 to different preset areas of the same spiral plate. Ultimately, this provides a stable and uniform ore liquid supply for the spiral concentrator, ensuring efficient separation operations.
