Description
Technical Field
[0001] The utility model relates to the technical field of coal washing, in particular to a novel coal washing device. Background Art
[0002] Coal is a solid, combustible mineral, formed primarily from the remains of ancient plants undergoing complex biochemical and physicochemical changes underground. It is an important energy source for industrial development. The heat energy generated by coal combustion can be converted into electricity for household, commercial, and industrial use. During coal mining and processing, raw coal often contains a large amount of impurities, which reduces its calorific value. Therefore, the raw coal needs to be cleaned. During the cleaning process, the raw coal is placed in a cleaning container and stirred by a stirring paddle to separate the coal from the impurities.
[0003] In the existing technology, the coal is stirred and cleaned only by the mechanical stirring action of the stirring paddle. Although it can achieve the mixing of coal and water and a certain degree of impurity separation, it is difficult to penetrate the impurities inside the coal particles or in the small gaps, and the coal particles in some areas may not be fully cleaned.
[0004] In order to solve the above problems, this application proposes a new type of coal washing device. Utility Model Content

[0009] A piston reciprocating member is slidably arranged in the cylinder member, and a driving member for driving the tubular stirring exhaust member to rotate and drive the piston reciprocating member to move back and forth laterally in the cylinder member is installed on the coal washing box.
[0010] Preferably, the tubular stirring exhaust member includes an exhaust pipe, which is vertically arranged in the cleaning chamber and driven to rotate by a driving member. A stirring paddle for material stirring is installed on the exhaust pipe, and a plurality of vertically spaced air holes are opened on the outer periphery of the exhaust pipe.
[0011] Preferably, the gas cylinder component includes a gas cylinder body, which is laterally installed on the side of the top of the coal washing box. An air cavity is provided in the gas cylinder body.

The tubular stirring exhaust member can stir the raw coal in the cleaning chamber when rotating, so that it is fully mixed with the water. When the piston reciprocating member moves back and forth in the gas cylinder member, the gas can be reciprocated along the gas guide member to the tubular stirring exhaust member to be discharged through the tubular stirring exhaust member, and bubbles are generated in the water in the cleaning chamber to pass through the raw coal. This structure introduces gas into the coal washing box when the raw coal is stirred, so that a large number of bubbles are generated in the water to pass through the coal. These bubbles drive the water flow and coal particles to move during the rising process, forming a strong turbulent effect. This turbulence not only helps the coal particles to mix more fully with the water, but also penetrates into the coal particles and small gaps, effectively strips off impurities and discharges them with the water flow, thereby significantly improving the cleaning efficiency.

[0027] In this embodiment, the tubular stirring exhaust member 2 includes an exhaust pipe 21, which is vertically arranged in the cleaning chamber and driven to rotate by the driving member 6. A stirring paddle 22 for material stirring is installed on the exhaust pipe 21, and a plurality of vertically spaced air holes 23 are opened on the outer periphery of the exhaust pipe 21.
[0028] In this embodiment, the gas cylinder component 3 includes a gas cylinder body 31, which is horizontally installed on the side of the top of the coal washing box 1. An air cavity is opened in the gas cylinder body 31. The top and bottom of the gas cylinder body 31 near one end of the coal washing box 1 are respectively connected to a one-way air inlet valve 32 and a one-way air outlet valve 33 that are connected to the air cavity.
[0029] In this embodiment, the air guide member 4 includes a rotary joint 41, which is installed at the bottom of the coal washing box 1.

[0030] In this embodiment, the piston reciprocating member 5 includes a rotating rod 51. An assembly block 7 located above the gas cylinder body 31 is installed on the side of the top of the coal washing box 1. The rotating rod 51 is installed on the assembly block 7 and is driven to rotate by the driving member 6. A turntable 52 is installed at the bottom end of the rotating rod 51.
