Description

Technical Field

[0001] This utility model belongs to the field of tailings recovery technology, specifically relating to a tailings recovery machine for dry tailings discharge and dewatering. Background Technology

[0002] The main function of a tailings recovery machine is to wash, dewater, and classify sand and gravel, and to recover the large amount of fine sand lost by sand washing machines in the traditional sand making industry. This not only improves economic efficiency but also reduces tailings processing costs, while minimizing environmental pollution and damage caused by lost fine sand.

[0003] The working principle of the tailings recovery machine is relatively complex, but the process is clear. The concentrated tailings are fed to the dewatering screen through the underflow nozzle. The finished material from the sand washing machine directly enters the dewatering screen for dewatering. The mud and water discharged from the sand washing machine enter the cleaning tank of the equipment and are drawn to the high-pressure separator by the bottom vacuum high-pressure pump for separation and concentration. The fine sand enters the dewatering screen through the underflow nozzle, while other wastewater, mud, powder, impurities, etc. are discharged into the return water tank through the overflow port of the high-pressure separator.

[0004] After washing the sand and gravel, the sand washing machine discharges wastewater containing a large amount of mud. This muddy water is then guided into the washing tank of the equipment for further purification. However, during the process of the muddy water passing through the washing tank, due to the high specific gravity, irregular shape, and rough surface of the sand and gravel particles, they easily adhere to the inner wall and bottom of the washing tank.

[0005] Over time, more and more sand and gravel particles adhere to the inside of the washing tank. This not only occupies the effective volume of the washing tank, reducing its processing capacity, but also prevents some sand and gravel particles from being effectively recycled. As a result, the recovery rate of sand and gravel particles is significantly reduced, thus affecting the efficiency and economic benefits of the entire sand washing process. Utility Model Content

[0006] The purpose of this utility model is to provide a tailings recovery machine for dry tailings discharge and dewatering, which aims to solve the problem that existing sand and gravel particles easily adhere to the inner wall and bottom of the washing tank, which not only occupies the effective volume of the washing tank and reduces its processing capacity, but also makes it impossible to effectively recover some sand and gravel particles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tailings recovery machine for dry tailings discharge and dewatering, comprising a washing tank and a dewatering shell, wherein the dewatering shell is installed on the top of the washing tank, a vibration motor is installed on the surface of the dewatering shell, a vacuum high-pressure pump is connected to the bottom side of the washing tank, a hose is connected to the output end of the vacuum high-pressure pump, a high-pressure separator is connected to the end of the hose, a return water tank is installed between the high-pressure separator and the washing tank, and a screen plate is installed on the bottom side of the dewatering shell;

[0011] In a preferred embodiment of this utility model of a tailings recovery machine for dry tailings discharge and dewatering, the threaded rod and the threaded pipe are connected by a thread, and the threaded rod forms a rotating structure with the cleaning box through a bearing ring.

[0012] As a preferred embodiment of the tailings recovery machine for dry tailings discharge and dewatering according to this utility model, the inner wall of the dewatering shell is connected to a first screen, the surface of the washing tank is connected to a support, the surface of the support is mounted with a bearing seat, the inside of the bearing seat is connected to a conveyor roller, the surface of the conveyor roller is sleeved with a conveyor belt, the end of the conveyor roller is mounted on the output end of a second drive motor, and the side surface of the support is connected to a discharge trough.

[0013] As a preferred embodiment of the tailings recovery machine for dry tailings discharge and dewatering according to this utility model, the conveying rollers are symmetrically arranged on both sides of the dewatering shell, and the conveying rollers form a rotating structure between the bearing seat and the support.

In this way, the cleaning brush can clean the side wall and bottom of the cleaning tank, so that the attached tailings particles can enter the sewage for recycling again, thereby improving the tailings recovery rate.

[0017] In this invention, the slurry concentrated by the high-pressure separator can be screened through a first screen. Tailings particles larger than the filter holes of the first screen gradually move towards the side of the conveyor belt under the action of vibration. When the large tailings particles fall from the end of the first screen onto the surface of the conveyor belt, the second drive motor drives the conveyor belt to rotate through the conveyor roller, which can realize the conveying of the large tailings particles. The large tailings particles fall into the surface of the discharge trough from the end of the conveyor belt and are discharged. In this way, the tailings particles can be screened according to their size. Attached Figure Description

[0027] First, the tailings wastewater after washing is concentrated by the high-pressure separator 6. The concentrated tailings are supplied to the surface of the screen plate 8 of the dewatering shell 2 through the sand discharge nozzle of the high-pressure separator 6. The vibration of the dewatering shell 2 is driven by the vibration of the vibration motor 3. The vibration of the screen plate 8 driven by the dewatering shell 2 can effectively separate the tailings from the water. The separated mud water enters the cleaning tank 1 of the equipment and is drawn into the high-pressure separator 6 through the vacuum high-pressure pump 4 at the bottom and the hose 5 for separation and concentration. The fine sand enters the dewatering shell 2 through the sand discharge nozzle of the high-pressure separator 6. Other wastewater, mud, powder, impurities, etc. are discharged into the return water tank 7 through the overflow port of the high-pressure separator 6.

[0028] Preferably, a sliding sleeve 14 is connected to the side surface of the cleaning rack 9, and a slide rail 15 is connected to the inner wall of the cleaning tank 1 near the sliding sleeve 14. The sliding sleeve 14 and the slide rail 15 are symmetrically arranged on both sides of the cleaning rack 9, and the sliding sleeve 14 and the slide rail 15 are slidably connected.

[0029] In actual use, when the cleaning rack 9 is subjected to a force, it can drive the sliding sleeve 14 to slide on the surface of the slide rail 15, which can limit the movement direction of the cleaning rack 9 and thus ensure the stability of the cleaning rack 9 during operation.

[0030] Preferably, the threaded rod 11 and the threaded tube 10 are connected by a thread, and the threaded rod 11 forms a rotating structure with the cleaning box 1 through the bearing ring 12.

[0031] In practical use, when the threaded rod 11 rotates, it can drive the threaded tube 10 to move laterally through the threaded connection, and the lateral movement of the threaded tube 10 can drive the cleaning rack 9 to move laterally.

[0032] Preferably: the inner wall of the dehydration shell 2 is connected to a first screen 17, the surface of the washing tank 1 is connected to a bracket 18, the surface of the bracket 18 is mounted with a bearing seat 19, the inside of the bearing seat 19 is connected to a conveyor roller 20, the surface of the conveyor roller 20 is sleeved with a conveyor belt 21, the end of the conveyor roller 20 is mounted on the output end of the second drive motor 22, and the side surface of the bracket 18 is connected to a discharge trough 23.

[0035] Preferably, the conveyor belt 21 is located on the bottom side of the end of the first screen 17.

[0036] In practical use, the large tailings particles screened by the first screen 17 can be conveyed by the rotation of the conveyor belt 21, so that the large tailings particles can be discharged from the side surface of the washing box 1.

[0037] Working principle: When using this tailings recovery machine, the slurry concentrated by the high-pressure separator 6 can first fall onto the surface of the first screen 17. In this way, tailings particles larger than the filter holes of the first screen 17 cannot fall off its surface. When the vibrating motor 3 drives the first screen 17 to vibrate through the dewatering housing 2, the large tailings particles can gradually move towards the side of the first screen 17 closer to the conveyor belt 21. When the large tailings particles fall from the end of the first screen 17 onto the surface of the conveyor belt 21, the second drive motor 22 runs and drives the conveyor roller 20 to rotate. The rotation of the conveyor roller 20 drives the conveyor belt 21 to rotate, so that the large tailings particles can be transported to one side of the washing tank 1 and discharged onto the surface of the discharge trough 23 through the rotation of the conveyor roller 20.

[0038] When tailings particles adhere to the inner wall of the cleaning tank 1 and need to be cleaned, the first drive motor 13 can be operated. When the first drive motor 13 is running, it can drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, it can drive the threaded tube 10 to move laterally. The lateral movement of the threaded tube 10 can drive the cleaning frame 9 to move laterally. The lateral movement of the cleaning frame 9 can drive the cleaning brush 16 to move laterally. In this way, the side walls and bottom of the cleaning tank 1 can be cleaned by the cleaning brush 16.
