[0002] Coal is a solid combustible mineral that was gradually formed when ancient plants were buried underground and experienced complex biochemical and physical and chemical changes. Coal is also known as black gold and food for industry. It has been one of the main energy sources used by the human world since the 18th century. Coal slag is a kind of industrial solid waste, which is the waste residue discharged from coal-fired power plants, industrial and civil boilers and other equipment, also known as slag. The main components are silicon dioxide, aluminum oxide, iron oxide, calcium oxide, magnesium oxide, etc. Depending on the composition, it can be used to make cement, bricks and refractory materials. Some can be used to make aluminum oxide or refine rare metals such as gallium and germanium.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 As shown, this embodiment provides a waste slag treatment device for coal production, including a crushing box 1, a crushing chamber is provided in the crushing box 1, and two crushing rollers 4 are rotatably installed in the crushing chamber;

[0023] A feed port 2 connected to a crushing chamber is provided at the top of the crushing box 1, an air drying device is installed in the crushing chamber, an impeller 3 is rotatably installed in the crushing chamber, and the impeller 3 can block the feed port 2. A dust collecting box 5 is installed on one side of the crushing box 1, and the dust collecting box 5 is connected to the crushing chamber.

[0024] like Figure 2 As shown, when the coal waste needs to be crushed, the coal waste is poured into the feed port 2, and the coal waste falls into the gap between the blades of the impeller 3. At the same time, the impeller 3 rotates, and the coal waste falling between the blades of the impeller 3 is rotated and falls onto the crushing roller 4 for crushing. Figure 2 A tilted triangular plate is also installed in the middle to ensure that the uncrushed coal slag will not fall directly below. During the rotation of the impeller 3, the feed inlet 2 is in a relatively blocked state.

[0025] The top of the dust box 5 is open, and an inclined guide plate 14 is installed in the dust box 5. A dust filter plate 6 is installed on the top of the dust box 5 to block the top opening of the dust box 5. The dust filter plate 6 can filter dust; the dust filter plate 6 is a plate-like structure with multiple holes for filtering dust, or a filter cloth is installed in the middle of a square frame.

[0026] like Figure 3 As shown, a material shaking structure is installed on the dust box 5, and the material shaking structure includes a lifting column 12 and a shaking spring 13; the lifting column 12 is connected to the bottom end of the dust filter plate 6, and the top surface of the dust box 5 is provided with a telescopic hole that slides with the lifting column 12, and the shaking spring 13 is sleeved on the lifting column 12, and the compression spring 15 is located in the telescopic hole, and the compression spring 15 is sleeved on the lifting column 12. The installation positions of the shaking spring 13, the compression spring 15 and the lifting column 12 are as shown in FIG. Figure 3 The shaking structure is used to drive the dust filter plate 6 to shake back and forth.

[0027] One side of the crushing box 1 is provided with an insertion slot which is in communication with the crushing chamber. A collecting box 7 is detachably inserted into the insertion slot. The collecting box 7 is located directly below the two crushing rollers 4 .

[0028] The air-drying device includes an air-drying box 8, a fan 9 and a heating tube 10; the air-drying box 8 is installed on one side outer wall of the crushing box 1, and the air-drying box 8 and the crushing chamber are connected, the fan 9 is installed in the air-drying box 8, and the blowing direction of the fan 9 is toward the crushing chamber; the heating tube 10 is installed in the air-drying box 8.

[0029] The dust collecting box 5 is installed on the outer wall of the crushing box 1 away from the air drying box 8. An air outlet is opened on the side of the crushing box 1 away from the air drying box 8. The collecting box 7 is located at the middle height position of the air outlet. A filter screen 11 is installed on the upper half of the air outlet.

[0030] When the coal waste is crushed, the coal waste is poured into the feed port 2, and then the impeller 3 is driven by the motor. Figure 2 The impeller 3 rotates clockwise, and the poured coal slag falls from the right side of the impeller 3 to the two rotating crushing rollers 4. The two crushing rollers 4 crush the coal slag and then drop it into the collecting box 7 below. At the same time, the fan 9 and the heating tube 10 are powered on, and the fan 9 blows the hot air heated by the heating tube 10 into the crushing chamber. The blown hot air dries the crushed coal slag that falls down. At the same time, the blowing blows the dust mixed in the coal slag particles into the dust box 5 on the right. The filter screen 11 can prevent some small blocks from being blown into the dust box 5 by the hot air. Figure 2 The inclined triangular plate and the crushing roller 4 in the middle play the effect of isolating the hot air. When the hot air reaches the feed port 2, it is blocked by the rotating impeller 3, which can prevent the dust in the crushing chamber from being discharged from the feed port 2 and inhaled by the staff. The hot air in the crushing chamber dries the coal waste particles that fall into the collecting box 7. The moisture is blown into the dust box 5 by the hot air. When the hot air enters the dust box 5, it contacts the inclined guide plate 14, which makes the hot air move upward along the inclined surface of the guide plate 14, and the dust falls. The dust is collected at the bottom of the dust collecting box 5, and part of the dust is filtered out from the dust filter plate 6 along with the hot air. The hot air blows the dust filter plate 6 upward, and the dust filter plate 6 compresses the compression spring 15. The reaction force of the compressed compression spring 15 drives the lifting column 12 in the opposite direction, so that the lifting column 12 reciprocates. The reciprocating lifting column 12 drives the dust filter plate 6 to shake back and forth, and the dust particles against the bottom of the dust filter plate 6 are shaken off, so as to avoid excessive dust accumulation on the bottom of the dust filter plate 6 and cause blockage.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
