Description

Technical Field

[0001] This invention belongs to the technical field of material cleaning in mineral processing, coal, water treatment, and environmental protection, and specifically relates to a mineral processing return water sedimentation tank ore cleaning and transfer device and its usage method. Background Technology

[0002] In the mineral processing, coal preparation, and water treatment industries, return water sedimentation tanks serve as transfer stations for return water reuse, playing a crucial role in secondary sedimentation, storage, and on-site return water supply. Over long-term use, due to thickener overflow and mixing, solid particles carried in the return water accumulate in the sedimentation tanks, reducing their volume and affecting normal water supply to the production site. Currently, cleaning accumulated ore involves shutting down the sedimentation tanks, draining the return water, and then drying the ore until it is semi-dry or fully dry. Loaders and dump trucks are then used to clean and transport the ore to the concentrate and tailings storage center. This method requires draining water and shutting down the production line, impacting on-site operations. Furthermore, the drying and cleaning process is lengthy, easily generating dust and causing ore leakage, polluting the environment. Therefore, there is an urgent need to develop a convenient, environmentally friendly, and uninterrupted transfer device and method for cleaning accumulated ore in mineral processing return water sedimentation tanks. Summary of the Invention

[0003] The purpose of this invention is to provide a device for cleaning and transferring ore accumulated in a mineral processing backwater sedimentation tank and its usage method, so as to solve the problems in the prior art where cleaning ore accumulated in a backwater sedimentation tank requires emptying the sedimentation tank, drying, and shoveling, which affects upstream production water supply and production, and is time-consuming, costly, and prone to dust pollution.

[0004] The technical solution of the present invention is: a mineral processing water sedimentation tank ore cleaning and transfer device, comprising a suspension stirring cleaning device and a transfer and concentration adjustment device; The suspended mixing and cleaning device includes a rectangular main suspended support frame, a platform-shaped and hollow three-dimensional support frame is provided above the middle of the main suspended support frame, a chain hoisting lug is provided on the inner side of the top of the three-dimensional support frame, the chain hoisting lug is connected to the mixing pump through an electric chain hoist, and a power support frame is provided on both sides of the three-dimensional support frame, and a drive impeller is provided on each of the power support frames. The transfer and concentration adjustment device includes a transfer pump tank, which is connected to a stirring pump via a wire mesh pipe. A concentration adjustment gate is provided on the side of the transfer pump tank, and a screw is connected to the concentration adjustment gate. A handwheel is provided on the screw. The transfer pump is also provided on the transfer pump tank, and the transfer pump is connected to a head pipe.

[0005] As a further improvement of the present invention, the main suspension support is also provided with a fault traction rope, and a traction device is connected to the fault traction rope.

[0006] As a further improvement of the present invention, a main body float is provided below the main body suspension support, which is arranged in a ring symmetrical arrangement and has a hollow center.

[0007] As a further improvement of the present invention, the middle section of the wire mesh pipe is provided with an auxiliary support and an auxiliary float.

[0008] As a further improvement of the present invention, the top of the three-dimensional support is provided with an umbrella-shaped rain cover.

[0009] As a further improvement of the present invention, the electric chain hoist, stirring pump, drive impeller, and transfer pump can all be remotely controlled.

[0010] A method for using a mineral processing wastewater sedimentation tank ore cleaning and transfer device includes the following steps: Step 1: When it is necessary to clean the accumulated ore in the return water sedimentation tank, turn on the corresponding drive impeller to move the entire suspended stirring cleaning device toward the fixed position. After reaching the fixed position, the drive impeller stops working, and the electric chain hoist drives the stirring pump to submerge below the water surface. After the stirring pump submerges and contacts the ore surface, it stops submerging and turns on the stirring pump to stir and suck up the deposited sludge. Step 2: The slurry reaches the transfer pump pool through the wire mesh pipe. The transfer pump is turned on, and the slurry is pressurized by the transfer pump and transported to the thickener feed box through the transfer pump head pipe. If the slurry concentration is too high during the transportation process, the handwheel can be operated to lower the concentration regulating gate of the pump pool under the drive of the screw. The water in the sedimentation tank enters the transfer pump pool through the concentration regulating gate of the pump pool to regulate and dilute the slurry concentration in the transfer pump pool. Step 3: After the accumulated ore in this area is cleared, small-scale movement is required. Activate the corresponding drive impeller to move the suspension mixing and cleaning device. If large-scale movement is needed, first stop the mixing pump and transfer pump. Allow the electric chain hoist to move the mixing pump upwards above the water surface, then stop the electric chain hoist. Operate the drive impeller control box to activate the corresponding drive impeller, thus moving the suspension mixing and cleaning device. The beneficial effects of this invention are as follows: 1. This solves the problem that in the existing technology, cleaning the accumulated ore in the return water sedimentation tank requires emptying the sedimentation tank and drying it before mechanical cleaning, which affects normal production, is time-consuming and expensive, and is prone to generating dust pollution.

[0011] 2. This invention enables convenient and non-stop cleaning of ore accumulation in the ore return sedimentation tank, and provides a device and method for cleaning and transferring ore accumulation in the ore return sedimentation tank.

[0012] 3. It enables rapid and efficient cleaning of accumulated minerals in the return water sedimentation tank, significantly shortening the cleaning time, achieving real-time cleaning, and at the same time, reducing cleaning costs significantly.

[0013] 4. The cleaning method is advanced and realizes the circulation of accumulated ore within the process, avoiding the discharge and leakage of accumulated ore that may affect environmental safety.

[0014] 5. The cleaning device is easy to operate, the operation process is automated, and environmental hazards during the operation are eliminated. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1 like Figures 1-3 As shown, a mineral processing wastewater sedimentation tank ore cleaning and transfer device includes a suspension stirring cleaning device and a transfer and concentration adjustment device. The suspended mixing and cleaning device includes a rectangular main suspended support 2. A platform-shaped and hollow three-dimensional support 1 is provided above the middle of the main suspended support 2. A chain hoisting ear 4 is provided on the inner side of the top of the three-dimensional support 1. The chain hoisting ear 4 is connected to a mixing pump 6 through an electric chain hoist 7. Power supports 3 are provided on both sides of the three-dimensional support 1. Each power support 3 is equipped with a separately controlled drive impeller 8. The transfer and concentration adjustment device includes a transfer pump pool 13, which is connected to a stirring pump 6 via a wire mesh pipe 9. A concentration adjustment gate 14 is provided on the side of the transfer pump pool 13, and a lead screw 15 is connected to the concentration adjustment gate 14. A handwheel 16 is provided on the lead screw 15. A transfer pump 17 is also provided on the transfer pump pool 13, and the transfer pump 17 is connected to a head pipe 18.

[0019] The main suspension support 2 is also equipped with a fault traction rope, to which a traction device is connected. Below the main suspension support 2 are symmetrically arranged, centrally hollow main floats 5. The middle section of the wire mesh pipe 9 is equipped with an auxiliary support 11 and an auxiliary float 12. The top of the three-dimensional support 1 is equipped with an umbrella-shaped rain cover 10. The electric chain hoist 7, agitator pump 6, drive impeller 8, and transfer pump 17 can all be remotely controlled.

[0020] When it is necessary to clean the accumulated ore in the return water sedimentation tank, the entire device is powered on. After determining the cleaning location, the corresponding drive impeller 8 is activated by controlling the drive impeller control box, which drives the entire suspension mixing cleaning device to move towards the fixed position. After reaching the fixed position, the drive impeller 8 is stopped by controlling the drive impeller control box. The electric chain hoist 7 is operated by operating the electric chain hoist controller, which drives the mixing pump 6 to submerge below the water surface. After the mixing pump 6 submerges to a certain depth below the water surface and contacts the ore accumulation surface, it stops submerging. The mixing pump control box is operated to start the mixing pump 6. The mixing pump 6 agitates and sucks up the deposited sludge, which is then transported to the transfer pump pool 13 through the wire mesh pipe 9. The transfer pump control box is operated to start the transfer pump 17. The slurry is pressurized by the transfer pump 17 and transported to the thickener feed box through the transfer pump head pipe 18.

[0021] If the slurry concentration is too high during the transportation process, the handwheel 16 on the transfer pump pool 13 can be operated. Driven by the screw 15, the pump pool concentration regulating gate 14 will drop, and the water in the sedimentation tank will enter the transfer pump pool 13 through the pump pool concentration regulating gate 14 to regulate and dilute the slurry concentration in the transfer pump pool 13.

[0022] After the ore deposits in this area are cleared, for small-scale movements, the drive impeller control box can be directly operated to activate the corresponding drive impeller 8, which will move the suspension mixing and cleaning device. For large-scale movements, the mixing pump 6 and transfer pump 17 must be stopped first. The electric chain hoist 7 is then operated by the electric chain hoist controller to drive the mixing pump 6 upwards until it reaches above the water surface. The electric chain hoist 7 is then stopped, and the drive impeller control box is operated to activate the corresponding drive impeller 8, which will move the suspension mixing and cleaning device.

[0023] The above describes the normal operating procedure of this ore cleaning and transfer device.

[0024] After prolonged operation, some components of the ore cleaning and transfer device may malfunction. In such cases, maintenance requires moving the device to the shore of the return water sedimentation tank. To prevent the drive impeller from failing and becoming immobile, the device is equipped with a fault traction device, which consists of two main parts: a fault traction rope and a traction rope tensioning device. During normal operation, the traction rope tensioning device only serves to tighten the fault traction rope, with a relatively small force. When the ore cleaning and transfer device malfunctions, the traction rope tensioning device is rotated to apply a larger force to the ore cleaning and transfer device through the fault traction rope, causing it to move towards the shore for maintenance.

[0025] The four parts—suspension stirring cleaning device, transfer and concentration adjustment device, control system, and fault traction device—are assembled together to form a complete sedimentation tank ore accumulation cleaning, concentration adjustment, transfer, and device fault traction system, which can independently carry out ore accumulation cleaning at the bottom of the tank.

[0026] The suspended mixing and cleaning device is equipped with a three-dimensional support frame 1, a main suspended support frame 2, and a power support frame 3. The three supports are connected by bolts, which is advantageous for easy disassembly, assembly, and maintenance. The top inner side of the three-dimensional support frame 1 is equipped with a chain hoist lug 4, which facilitates the later suspension of an electric chain hoist 7 and a mixing pump 6. The main suspended support frame 2 is rectangular, with a main float 5 installed below it, reserving space for the mixing pump 6 to submerge. The main float 5 is arranged in a circular symmetrical pattern with a hollow center, which is advantageous for providing stable buoyancy without affecting the submersion of the mixing pump 6. There are four power supports 3, distributed at the four corners below the main suspended support frame 2, each equipped with a drive impeller 8. The four impellers are individually controlled, which is advantageous for controlling the entire suspended mixing and cleaning device to move in different directions in the sedimentation tank and clean the accumulated minerals in different locations. The electric chain hoist 7 is suspended on the chain hoist lug 4, with the mixing pump 6 suspended below it. Its advantage is that it is advantageous for conveniently controlling the vertical movement of the mixing pump 6, efficiently mixing and cleaning accumulated minerals at different depths.

[0027] The transfer and concentration adjustment device is equipped with a transfer pump pool 13. The slurry transported from the wire mesh pipe 9 enters the transfer pump pool 13. The transfer pump pool 13 is equipped with a concentration adjustment gate 14 near the sedimentation tank. The height of the gate can be adjusted by turning the handwheel 16, which drives the screw 15 to control the amount of sediment water entering the pump pool. Its advantage is that it can conveniently adjust the slurry concentration in the pump pool, preventing the concentrated slurry from entering the head pipe 18 through the transfer pump 17 and causing slurry deposition and blockage of the pipe during long-distance dredging. The settled slurry enters the thickener through the transfer pump 17 and the head pipe 18. Its advantage is that it realizes the circulation of the accumulated slurry within the process and avoids the leakage of accumulated slurry from affecting environmental safety.

[0028] The stirring pump 6 is connected to the wire mesh pipe 9. Its advantage is that the wire mesh pipe 9 has high strength and can be bent, making it easy to move and change direction. The outlet of the wire mesh pipe 9 is connected to the transfer and concentration adjustment device. In the middle section of the wire mesh pipe 9, depending on the different specifications, an auxiliary support 11 and an auxiliary float 12 are set. Its advantage is that it can provide stable buoyancy for the wire mesh pipe 9 and prevent it from sinking into the water.

[0029] The main suspended support 2 is also equipped with a fault traction rope, and a traction device is set up at the edge of the sedimentation tank. Its advantage lies in its ability to pull the device to the edge of the tank in case of failure, facilitating inspection and maintenance. The top of the three-dimensional support 1 is equipped with a rain cover 10, which helps prevent outdoor rain and snow from corroding the equipment below. The electric chain hoist 7, stirring pump 6, drive impeller 8, and transfer pump 17 of this ore cleaning and transfer device can all be remotely controlled. This avoids the need for personnel to move around inside the sedimentation tank, effectively ensuring the personal safety of operators.
