Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to an automated device for the treatment of settled sludge. Background Technology

[0002] Heap leaching-activated carbon static adsorption is a common production process in gold mines. In the precious liquor adsorption section, adsorption columns containing activated carbon are generally used to treat gold-bearing precious liquor, adsorbing gold complexes in the liquor. During carbon extraction and carbon transfer operations, a large amount of fine carbon-containing powder is generated due to friction between activated carbon particles and between activated carbon and the transport pipeline during transport. Since this carbon powder contains gold, and after being pumped to the stockpile with lean liquor, it adsorbs the leached gold on-site. If the sludge containing a large amount of carbon powder is not recycled, the gold recovery rate will decrease, resulting in economic losses. Generally, carbon powder needs to be recovered by filtration after adsorption. However, due to the small particle size of the carbon powder, the recovery capacity of a 200-mesh screen is limited. A better method is to use inclined tube settling. The amount of sludge produced by settling is large, the cleaning process is extremely labor-intensive, and the cleanup site is chaotic. Improvements are needed to automate the process to ensure increased production efficiency and reduced labor costs. Summary of the Invention

Detailed Implementation

[0022] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0023] Example 1

[0024] An automated device for treating settled sludge, such as Figure 1-5 As shown, it includes an inclined tube settling device, which includes a box and an inclined tube disposed inside the box; the inclined tube settling device is an existing mature product, and for structures not mentioned, please refer to existing solutions.

[0025] Furthermore, it also includes a controller (not shown in the figure). The bottom of the box is equipped with an air blowing and stirring mechanism. One side of the side wall of the box is connected to a sludge conveying pipeline 8. An electric control valve 9 is installed on the sludge conveying pipeline 8. One end of the sludge conveying pipeline 8 is connected to a sludge tank 10. A sludge pump 12 is connected to the bottom of the outer side of the sludge tank 10. A liquid level sensor 11 is installed inside the sludge tank 10. The sludge pump is used to convey sludge to the filter press. The controller is electrically connected to a power source. The liquid level sensor 11 is connected to the controller via a wire. The controller is configured to control the electric control valve 9, the sludge pump 12, and the air blowing and stirring mechanism.

[0026] In this embodiment, after the sludge containing carbon powder has settled sufficiently in the inclined tube settler, when this new technology is needed, the sludge pump is started to transport the sludge to the filter press for further processing. During this process, the air blowing and stirring mechanism can fully stir the sludge in the tank to prevent sludge caking. The controller controls the amount of sludge entering the sludge tank by controlling the opening and closing degree of the electric control valve, and then controls the amount of sludge discharged from the sludge tank by controlling the sludge pump, ensuring that the sludge in the sludge tank is within the set capacity range, avoiding sludge overflow and waste or damage to the sludge pump due to insufficient sludge.

[0027] Example 2

[0028] Based on Example 1, this example is further improved, such as... Figure 1-6 As shown, the air blowing and stirring mechanism includes several air rods 13 arranged side by side at the bottom of the housing 25. Several air blowing pipes 14 are provided on both sides of the outer wall of the air rods 13. Several stirring components are provided at the bottom of the air rods 13. One end of the air rod 13 is closed and fixedly connected to the inner wall of the housing. The other end passes through the inner wall of the housing and is connected to the high-pressure air pipe 6 outside the housing. The input end of the high-pressure air pipe 6 is connected to an air compressor (not shown in the figure). The air compressor is electrically connected to the controller through a wire.

[0029] In this embodiment, compressed air from the air compressor enters the high-pressure air pipe, then enters each ventilation rod 13, and is discharged through the air blowing pipe. The air blowing stirs the sludge and prevents it from caking.

[0030] Example 3

[0031] Based on Example 2, this example is further improved, such as... Figure 1-6 As shown, the high-pressure air pipe 6 is made of galvanized steel pipe. Several joints are connected to the side wall of the high-pressure air pipe 6. One end of the air rod 13 is connected to the joints. The air rod 13 is an elastic rubber tube that can vibrate during the air jet process, thereby driving the stirring component to move and realize the stirring action. The air blowing pipes on both sides of the air rod are set horizontally or inclined downward. The advantage of the latter is that as the sludge liquid level 24 drops, a continuous blowing and stirring effect can be achieved.

[0032] Furthermore, the stirring assembly includes a first vertical rod 17 whose top is ball-hinged to the bottom of the vent rod 13. The bottom of the first vertical rod 17 is connected to a second vertical rod 22 via a tension spring 21. The top of the second vertical rod 22 is connected to the bottom of the tension spring 21, and the bottom of the second vertical rod 22 is ball-hinged to the bottom 23 of the housing. A connecting plate 18 is fixedly provided on the upper part of the first vertical rod 17, and a movable plate 19 is hinged to the lower part. A strip hole is provided in the center of the movable plate 19, and a hinge shaft 191 is provided in the strip hole. The first vertical rod 17 passes through the strip hole and is hinged to the movable plate 19 via the hinge shaft 191. Two vibration springs 20 are symmetrically provided on both sides of the upper surface of the movable plate 19 about the hinge shaft 191. One end of the vibration spring 20 is connected to the outer surface of the connecting plate 18, and the other end is connected to the upper surface of the movable plate 19.

[0033] In this embodiment, the ventilator vibrates irregularly during ventilation, which in turn causes the movable plate to sway irregularly. As the movable plate sways, it interacts with the sludge and the vibration spring, further increasing the rotation amplitude of the movable plate and achieving a stirring effect on the sludge. After being stirred, the sludge becomes more fluid, facilitating its smooth discharge.

[0034] Example 4

[0035] Based on Example 3, this example is further improved, such as... Figure 1-5 As shown, a ramp structure 5 is provided on one side of the bottom 23 of the box body, and the bottom of the box body is an inclined surface that slopes downward toward the sludge conveying pipeline (not shown in the figure), which facilitates the flow of settled sludge toward the sludge conveying pipeline.

[0036] like Figure 2 As shown, the sludge output pipeline includes several branch pipes (not marked in the figure) connected to the bottom of the side wall of the tank, and several branch pipes are connected to a main drain pipe (not marked in the figure). The electric control valve is located on the main drain pipe, and the end of the main drain pipe is connected to the sludge tank 10. The bottom of the tank is higher than the connection between the main drain pipe and the sludge tank. During discharge, the sludge can slide to one side of the sludge tank by its own gravity.

[0037] Example 5

[0038] Based on Example 4, this example is further improved, such as... Figure 1-5As shown, the liquid level sensor 11 includes a first liquid level sensor located on the upper part of the inner wall of the sludge tank 10 and a second liquid level sensor located on the lower part of the inner wall. The first liquid level sensor is used to detect the maximum limit height of sludge in the sludge tank 10, and the second liquid level sensor is used to detect the minimum limit height of sludge in the sludge tank 10. When the minimum limit height is reached, the sludge pump needs to stop running to avoid damage to the sludge pump caused by dry pumping. At this time, the electric control valve can be fully opened. When the maximum limit height is reached, the opening of the electric control valve needs to be closed or reduced, while the sludge pump is kept running to ensure that the sludge discharge is greater than the input, thus preventing sludge from overflowing the sludge tank and causing waste.

[0039] like Figure 1 As shown, the upper part of the chamber is also equipped with a flushing pipe 2, which is connected to a water source via a connecting pipe. A solenoid valve (not shown in the figure) is installed on the connecting pipe and is electrically connected to a controller. When extracting sludge, the solenoid valve can be opened, allowing the water at the top of the chamber to impact the sludge downwards, promoting its smooth discharge. The arrangement of the flushing pipes can be set as needed; the water in the flushing pipes can either flow downwards through an inclined pipe to impact the sludge or be positioned in the gap between the inclined pipe and the side wall of the chamber to flush downwards.
