Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, specifically relating to a sand pump pool reversing pump device. Background Technology

[0002] In the daily production management of a mineral processing plant, sand pumps are used for slurry transportation, typically with one pump on standby and one in use. To avoid overloading one sand pump and to ensure the equipment's service life, it is necessary to periodically switch off the standby pump. Usually, switching off the standby pump requires manual labor or the use of electric hoists commonly used in hoisting processes to lift or lower the ore plugs in the pump pool (e.g., CN202223068009.5). This process involves long working hours, high labor intensity, and safety hazards for workers. Utility Model Content

[0003] To address the shortcomings of the aforementioned background technology, this utility model provides a sand pump pool reversing device, which can improve the work efficiency of the operation process and reduce safety hazards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic pump reversing device for a sand pump pool includes: an air compressor, a first cylinder, a second cylinder, a first sealing plug, a second sealing plug, a first flange, a second flange, a first solenoid valve, a second solenoid valve, a microcomputer time control switch, a tee, valves, and a pump pool;

[0006] The first solenoid valve and the second solenoid valve are installed in parallel on the air delivery pipe of the air compressor;

[0007] The first cylinder is connected to the air compressor via the first solenoid valve, and the lower end of its piston is connected to the first sealing plug.

[0008] The second cylinder is connected to the air compressor via the second solenoid valve, and the lower end of its piston is connected to the second sealing plug;

[0009] The first flange is located at the bottom of the pump pool, corresponding to the first sealing plug, and is connected to the operating pump through a pipeline;

[0010] The second flange is located at the bottom of the pump pool, corresponding to the second sealing plug, and is connected to the standby pump via a pipeline.

[0011] Furthermore, both the first and second sealing plugs are conical structures, wider at the top and narrower at the bottom, with their two sides forming a 45° angle with the horizontal direction. The outer diameter of the first sealing plug matches the inner diameter of the first flange, and its thickness matches the height of the first flange. Similarly, the outer diameter of the second sealing plug matches the inner diameter of the second flange, and its thickness matches the height of the second flange. Both the first and second sealing plugs are made of wear-resistant polyurethane material and coated with waterproof silicone. Both the first and second flanges have a 45° chamfer inside and are fixed to the ore inlet at the bottom of the pump pool using gaskets and bolts.

[0012] The first and second solenoid valves are both model 2V130-15 AC 220V.

[0013] The microcomputer time control switch, model KG316T-D AC220V, is used to independently set the working cycle of the first solenoid valve and the second solenoid valve; by periodically opening and closing the first solenoid valve and the second solenoid valve, the lifting and lowering movements of the first cylinder piston and the first sealing plug, and the second cylinder piston and the second sealing plug are controlled respectively.

[0014] The tee is installed on the air compressor's air delivery pipe and is located upstream of the first and second solenoid valves; the valve is installed at the interface between the tee and the air delivery pipe, and is used to discharge condensate and impurities from the air delivery pipe; specifically, the valve is a butterfly valve.

[0015] The beneficial effects of this utility model are as follows: by using a microcomputer time control switch and a solenoid valve to jointly control the cylinder piston to move the sealing plug up and down to a preset distance, the lower ore outlet of the sand pump pool can be sealed and opened, thus achieving the purpose of switching on the standby pump; in addition, the sealing plug and the flange are in seamless contact, which solves the problems of poor sealing and easy leakage of slurry caused by the original sealing plug; the condensate and impurities accumulated in the air pipe are discharged in advance, reducing operational errors caused by the failure of the solenoid valve electrical components, and significantly reducing the labor intensity and safety risks in the process of switching on the standby pump.
