Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a mobile placer gold processing device. Background Technology

[0002] Water is a crucial resource in placer gold beneficiation, thus limiting the process. Therefore, placer gold beneficiation typically involves transporting ore from the mining area to a location near a water source for centralized processing, significantly increasing transportation costs. Furthermore, the waste generated after centralized beneficiation must also be transported back to the mined area for backfilling, again incurring substantial transportation costs.

[0003] In the existing technology, there is a Chinese utility model patent with publication number CN213349270U entitled "Mobile Placer Gold Beneficiation Device". This device can realize on-site mineral beneficiation operations while simultaneously backfilling waste materials, saving transportation costs and improving economic efficiency. The "Z"-shaped material conveying structure effectively reduces the overall length of the device and improves stability during mobile operations. However, this device still has some inconveniences. First, the end-to-end horizontal connection between the concentrate chute and the dewatering screen results in an excessively long overall length of the equipment, which is not streamlined enough, and the equipment is large in size and occupies a large area. Second, it cannot reverse the conveying of concentrate materials (hereinafter referred to as concentrate) and slurry. Especially when cleaning the concentrate chute, the cleaned material needs to be collected separately to prevent it from directly entering the dewatering screen. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile placer gold beneficiation device to solve the problems of existing placer gold beneficiation devices, such as inconvenience in use, lack of simplification and compactness, large size, and inability to reverse the conveying of refined materials and slurry.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A mobile placer gold beneficiation device includes a mobile device and a feeder, a vibrating screen, a concentrate sluice, a reversing mechanism, a concentrate bin, a dewatering screen, a waste conveyor, and a water supply mechanism mounted on the mobile device. The feeder, the vibrating screen, and the concentrate sluice are connected in sequence. The discharge end of the concentrate sluice is connected to the feed end of the concentrate bin and the feed end of the dewatering screen through the reversing mechanism. The water outlet of the water supply mechanism is connected to the water inlet of the concentrate sluice. The feed end of the waste conveyor is connected to the discharge ends of the vibrating screen and the dewatering screen.

[0006] A further technical solution is: the mobile device is provided with a water collection tank located below the dewatering screen, and the concentrate bin is rotatably mounted on the mobile device, with the concentrate bin rotating towards the water collection tank.

[0007] A further technical solution is: the mobile device is equipped with a slurry pump that is connected to the water collection tank, and the upper part of the slurry pump is equipped with a start-up water supply tank.

[0008] A further technical solution is that the concentrate chute, the reversing mechanism, the concentrate bin, and the dewatering screen are arranged on both wings of the mobile device.

[0009] A further technical solution is that the driver's seat is located between the two fine material chutes.

[0010] A further technical solution is: the feeding end of the feeder is provided with an airfoil grid, and slides are provided on both sides of the airfoil grid.

[0011] A further technical solution is that a buffer plate is provided inside the airfoil grid.

[0012] A further technical solution is that the reversing mechanism is a gate valve.

[0013] A further technical solution is: the water supply mechanism includes a rotary tower crane and a tower frame, the rotary tower crane is mounted on the mobile equipment, the tower frame is mounted on the rotating end of the rotary tower crane, and the tower frame is provided with a water pipe communicating with the water inlet end of the fine material chute.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes a mobile placer gold beneficiation device. In this device, an outlet reversing mechanism is added to the tail end of the concentrate chute. During cleaning, the reversing mechanism controls the flow of concentrate to the concentrate bin; during gold placer beneficiation, it controls the flow of slurry to the dewatering screen, achieving automatic switching between the concentrate and slurry flow directions, thus improving the automation and practicality of the device. Furthermore, the concentrate chute and dewatering screen are staggered to avoid excessive length due to lateral connections, thereby reducing the overall size of the equipment.

[0028] This implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a mobile placer gold beneficiation device includes a mobile device 1 and a feeder 2, a vibrating screen 3, a concentrate chute 4, a reversing mechanism 5, a concentrate bin 6, a dewatering screen 7, a waste conveyor 8, and a water supply mechanism 9 installed on the mobile device 1. The feeder 2, the vibrating screen 3, and the concentrate chute 4 are connected in sequence. The discharge end of the concentrate chute 4 is connected to the feed end of the concentrate bin 6 and the feed end of the dewatering screen 7 through the reversing mechanism 5. The water outlet end of the water supply mechanism 9 is connected to the water inlet end of the concentrate chute 4. The feed end of the waste conveyor 8 is connected to the discharge ends of the vibrating screen 3 and the dewatering screen 7.

[0029] Mobile device 1 is a hydraulic walking mobile chassis. It supports the entire weight of the equipment and performs installation and connection functions. It is mainly responsible for the lateral and longitudinal movement of the equipment, as well as turning and leveling the equipment in pit and uneven mineral deposits. The movement is achieved by alternating support from two sets of high and low outriggers on the chassis, which avoids the defects of the track reflecting the uneven terrain on the entire equipment and affecting the normal operation of the equipment.

[0030] The feeding machine 2 is an inclined conveyor. A loader transports the placer gold ore raw material onto the feeding machine 2, which then conveys the material to the vibrating screen 3. The feeding rate of the feeding machine 2 is controlled according to the processing speed of the vibrating screen 3. The gold-containing material screened by the vibrating screen 3 enters the fine material chute 4. The water supply mechanism 9 provides washing water to the fine material chute 4. The fine material chute 4 sorts and contains the placer gold. The slurry flows directly to the dewatering screen 7 through the reversing mechanism 5. The dewatering screen 7 is located below the fine material chute 4 and the two are connected end to end, which greatly saves the equipment space. The dewatered material and the material screened by the vibrating screen 3 are also connected. Gold-containing or low-gold-containing slag is backfilled into the mining area via waste conveyor 8. After a specific period of operation, the concentrate chute 4 can automatically (for details of the principle, see patents: 2025104197021 and 2025206257412) to clear the gold-containing concentrate from the concentrate chute 4. The gold-containing concentrate is diverted by the reversing mechanism 5 set at the tail outlet of the concentrate chute 4 and flows into the concentrate bin 6 by water flow impact. The concentrate bin 6 has sedimentation and drainage functions, and finally the gold-containing concentrate is settled inside. After a certain amount is reached, the next concentrate bin 6 is replaced.

[0031] Preferably, the mobile device 1 is provided with a water collection tank 10 located below the dewatering screen 7, and the fine material bin 6 is rotatably mounted on the mobile device 1, with the fine material bin 6 rotating towards the water collection tank 10.

[0032] The fine material bin 6 can tilt inward under external force to pour excess mud and water into the water collection tank 10. The fine material bin 6 can be lifted by an excavator, detached from the slot on the side of the mobile device 1, and transported to the next process for further sorting of gold.

[0033] Preferably, the mobile device 1 is equipped with a slurry pump 11 that is connected to the water collection tank 10, and a start-up water supply tank 12 is provided on the upper part of the slurry pump 11.

[0034] A slurry pump 11 is installed at the front of the mobile device 1 (hydraulic walking mobile chassis), mainly responsible for sending the mud and water in the water collection tank 10 back to the water source. Because the inner cavity of the slurry pump 11 needs to be filled with water in advance before it can be started, a start-up water tank 12 is specially designed on the upper part of the slurry pump 11. The control unit realizes the automatic sequence of water replenishment before starting, ensuring that the slurry pump 11 can start smoothly.

[0035] Preferably, the fine material chute 4, the reversing mechanism 5, the fine material bin 6, and the dewatering screen 7 are arranged on both wings of the mobile device 1. The symmetrical arrangement of the feed chute 4, reversing mechanism 5, feed bin 6, and dewatering screen 7 not only optimizes the space utilization of the mobile equipment 1, but also increases the output.

[0036] Preferably, the driver's seat 18 is located between the two feed chutes 4.

[0037] This allows the equipment operator to easily observe the operation of the material chutes 4 on both sides and correct or clear any instances of excessive material flow.

[0038] Preferably, the feed end of the feeder 2 is provided with an airfoil grid 13, and slide rails 14 are provided on both sides of the airfoil grid 13.

[0039] The wing-shaped grid 13 at the feed end of the feeder 2 is used to separate large stones (generally not less than 450 mm) so that they cannot enter the feeder 2 and fall into the open ground at the front of the equipment through the slides 14 on both sides of the wing-shaped grid 13. Preferably, a buffer plate 15 is provided inside the wing-shaped grid 13.

[0040] The buffer plate 15 is a conical plate, and material leakage holes can also be provided on it. This is to prevent the material from being damaged by impact when it is discharged at a high speed.

[0041] Preferably, the reversing mechanism 5 is a gate valve.

[0042] The reversing mechanism 5 is similar to a three-way structure, with one inlet and two outlets. The two outlets are connected to or disconnected from the fine material bin 6 and the dewatering screen 7 respectively by changing the position of the gate.

[0043] Preferably, the water supply mechanism 9 includes a rotary tower crane 16 and a tower frame 17. The rotary tower crane 16 is mounted on the mobile device 1, and the tower frame 17 is mounted on the rotating end of the rotary tower crane 16. A water pipe connected to the water inlet of the fine material chute 4 is mounted on the tower frame 17.

[0044] The vibrating screen 3 has a rotating tower crane 16 and a tower frame 17 on top, which support water supply and return pipelines. These can be controlled by a controller to rotate at appropriate angles. Based on the same rotating tower crane structure at the water supply point on the other side, this allows for flexible buffering of the pipeline span caused by changes in the distance between the mineral processing unit and the water supply truck on the opposite bank. The principle is as follows: Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
