Description

Technical Field

[0001] This utility model relates to the field of raw coal crushing technology, and more specifically to a raw coal crushing device. Background Technology

[0002] Raw coal plays an important role in industrial production, and the crushing process is a key link in coal processing. By crushing large pieces of raw coal into small particles that meet the requirements, the subsequent combustion, gasification, and coking processes can be satisfied.

[0003] Traditional raw coal crushing equipment typically uses hammer crushers. When the hammer crusher is working, it crushes the raw coal by impacting and rubbing against the raw coal with its hammers and other components. However, during the crushing process, the raw coal is broken from lumps into powder, which generates a large amount of dust that floats into the air. This coal dust not only causes serious environmental pollution but also poses a serious threat to the health of operators. In fact, if the indoor dust concentration is too high, it can even cause safety hazards such as dust explosions. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-4 As shown, a raw coal crushing device includes:

[0032] Box 1;

[0033] Mounting brackets 4 are symmetrically arranged inside the housing 1;

[0034] The crushing plates 7 are arranged in a linear array on the side wall of the mounting frame 4, and the crushing plates 7 have cavities 8 inside.

[0035] Nozzles 9 arranged in a linear array at the top of the crushing plate 7;

[0036] A sliding frame 11 is slidably disposed inside the housing 1;

[0037] The fixed plates 12 are arranged in a linear array on the side wall of the sliding frame 11 and are arranged crosswise with the breaking plate 7.

[0038] Specifically, when raw coal needs to be crushed, the raw coal is fed into the box 1 through the feed inlet, causing the lumpy raw coal to fall between the crushing plate 7 and the fixed plate 12. The sliding frame 11 is driven to move back and forth within the box 1, causing the fixed plate 12 to move back and forth within the gap between the two crushing plates 7. During the movement, the fixed plate 12 cooperates with the crushing plate 7 to squeeze the lumpy raw coal, causing it to be crushed into powder. During the crushing process, water is injected into the cavity 8 opened in the crushing plate 7, and the water in the cavity 8 is supplied to the nozzle 9. The nozzle 9 sprays water mist to cover the gap between the two adjacent crushing plates 7, so that the water mist can suppress the dust generated between the crushing plate 7 and the fixed plate 12, thereby preventing the dust from floating into the air and causing pollution.

[0039] In the above embodiment, by setting up an installation frame 4, a crushing plate 7, a cavity 8, a nozzle 9, a sliding frame 11, and a fixed plate 12 inside the housing 1, the dust generated during the crushing process can be easily handled. When raw coal is put into the housing 1, the fixed plate 12 is moved back and forth by driving the sliding frame 11, so that the fixed plate 12 and the two adjacent crushing plates 7 cooperate to crush the raw coal, so that the fixed plate 12 and the crushing plate 7 can crush the raw coal into powder. During the crushing process of the crushing plate 7, water mist is sprayed from the nozzle 9 installed at the top of the crushing plate 7 to cover the crushing area of ​​the raw coal, so that the dust generated during the crushing process can be quickly suppressed. This not only avoids the dust from floating into the air and causing environmental pollution and human injury, but also reduces the waste of water resources during the dust suppression process, and avoids the danger of dust explosion.

[0040] As a further embodiment of this utility model, a filter plate 3 is fixedly installed inside the housing 1, and a mounting bracket 4 is fixedly connected to the top of the filter plate 3.

[0041] Specifically, by installing filter plates 3 inside the housing 1, the raw coal fed into the housing 1 can fall onto the filter plates 3 for crushing. When the crushing plate 7 and the fixing plate 12 process the raw coal into powder, the coal powder will fall into the bottom of the housing 1 through the holes on the filter plates 3 for collection.

[0042] As another embodiment of this utility model, the mounting frame 4 has a water storage cavity 5 inside, and a water pump 6 is fixedly installed inside the water storage cavity 5. The water storage cavity 5 is connected to the cavity 8.

[0043] Specifically, when the raw coal is crushed, the water pump installed in the water storage chamber 5 pumps the stored water into the cavity 8, so that the water in the cavity 8 can supply the nozzle 9, thereby enabling the nozzle 9 to spray water mist to cover the gap between two adjacent crushing plates 7.

[0044] As another embodiment further provided in this utility model, the sidewall of the crushing plate 7 is provided with crushing teeth 10 arranged in a linear array.

[0045] Furthermore, the side wall of the fixing plate 12 is provided with teeth 13 arranged in a linear array.

[0046] Specifically, the crushing teeth 10 installed on the crushing plate 7 and the toothed buckles 13 installed on the fixing plate 12 work together to improve the crushing effect of raw coal and increase the crushing efficiency of raw coal.

[0047] As another embodiment of this utility model, a hydraulic rod 14 is fixedly installed on the side wall of the housing 1, and one end of the hydraulic rod 14 is fixedly connected to the sliding frame 11.

[0048] Specifically, the sliding frame 11 is driven by the hydraulic rod 14 to reciprocate within the housing 1, which in turn drives the fixed plate 12 to reciprocate, thereby enabling the fixed plate 12 to cooperate with the crushing plate 7 to crush the raw coal.

[0049] As another embodiment provided in this utility model, a baffle 15 is fixedly installed on the discharge port of the box 1.

[0050] Specifically, by installing a baffle 15 on the discharge port of the housing 1, dust can be prevented from drifting out of the discharge port, thus reducing dust pollution.

[0051] Working principle: When raw coal needs to be crushed, it is fed into the housing 1, falling onto the filter plate 3 and positioned between the crushing plate 7 and the fixed plate 12. A hydraulic rod 14 drives the sliding frame 11 to reciprocate, causing the fixed plate 12 to move reciprocally within the gap between adjacent crushing plates 7. This allows the fixed plate 12 to work with the crushing plates 7 to crush the raw coal. Furthermore, by installing crushing teeth 10 on the crushing plate 7 and toothed clips 13 on the fixed plate 12, the crushing effect of the crushing plates 7 and fixed plate 12 on the raw coal is improved, thus increasing the crushing efficiency. During crushing, a water pump 6 installed in the water storage chamber 5 pumps water into the cavity 8, supplying water to the nozzle 9. The nozzle 9 then sprays water mist to cover the gap between adjacent crushing plates 7, suppressing dust and preventing it from floating into the air and causing harm.

[0052] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
