Description

Technical Field

[0001] This utility model belongs to the field of coking technology, specifically a coal crushing and dust suppression mechanism for coking production. Background Technology

[0002] Coking is the process of producing coke by thermal decomposition and coking of coal at a high temperature of around 1000℃. In order to ensure that the coal can be fully coked, large pieces of coal are crushed into smaller pieces before coking, so that the coal can be fully exposed to the high temperature environment.

[0003] Among them, a search revealed that application number CN202021737483.0, a dust suppression device for a raw coal crusher, is described. This device features a buffer dust suppression box with atomizing nozzles installed on both sides of the discharge port of the raw coal crusher shell. This ensures that the raw coal at the discharge port is wetted and dusted, reducing the dust concentration at the discharge port, improving the surrounding environment, and reducing harm to workers. However, its shortcomings are as follows:

[0004] When workers use this type of raw coal crusher dust suppression device to crush coal, the raw water with a certain pressure in the inlet pipe is filtered by a filter screen installed in the buffer dust suppression box to prevent impurities from damaging the atomizing nozzles. The filtered raw water is then sprayed out through multiple atomizing nozzles on the side of the buffer dust suppression box to wet and suppress dust on the raw coal at the outlet. However, when the atomized water is sprayed out through multiple atomizing nozzles to suppress dust generated during coal crushing, the fixed position of the atomizing nozzles and their inability to move freely results in a relatively fixed range of atomized water sprayed from the nozzles. This means that dust farther away from the atomizing nozzles cannot effectively contact the atomized water for dust suppression, making the dust suppression effect of this type of raw coal crusher dust suppression device relatively poor. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the dust suppression effect of the above-mentioned raw coal crusher dust suppression device is relatively poor, and to provide a coal crushing dust suppression mechanism for coking production.

[0009] The movable cleaning mechanism comprises a screw slide rail, a sliding frame, a damping telescopic rod A, a movable frame A, an electric cleaning roller, a steel wire brush, and a damping telescopic rod B.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this utility model:

[0023] Example 1: Refer to Figure 1-5A coal crushing and dust suppression mechanism for coking production includes a hammer crusher 1, a feed inlet 101, a grid frame 102, an electric crushing roller 103, a crushing hammer 104, a slag discharge trough 105, a waste bin 106, a discharge outlet 107, a baffle 108, an electric telescopic rod 109, and a leather conveyor belt 8. The feed inlet 101 is embedded in the side of the hammer crusher 1. The grid frame 102 is fixedly installed on both sides of the inside of the hammer crusher 1, and the grid frame 102 is arranged in a relatively arc shape. The slag discharge trough 105 is embedded in the sides of the inside of the hammer crusher 1 near the grid frame 102. The waste bin 106 is located at the bottom of the slag discharge trough 105. The electric crushing roller 103 is rotatably mounted in the middle of the inside of the hammer crusher 1 via a bearing. The outer ring of the electric crushing roller 103 is fixedly mounted... The hammer crusher 1 is equipped with several breaker hammers 104 arranged in a parallel and equidistant manner. A discharge port 107 is embedded in the lower part of the hammer crusher 1. Baffles 108 are rotatably mounted on both sides of the inner wall of the discharge port 107 via a rotating shaft. Electric telescopic rods 109 are rotatably mounted on both sides of the inner wall of the discharge port 107 and below the opposite baffles 108 via a rotating shaft. A leather conveyor belt 8 is installed below the hammer crusher 1 near the discharge port 107. A rotating dust-suppressing and humidifying mechanism is installed above the inside of the feed inlet 101 to suppress dust and humidify the coal during feeding. A swing dust-suppressing mechanism is installed above the inside of the slag discharge trough 105 to suppress dust generated by the coal during crushing. Movable cleaning mechanisms are installed on both sides of the inside of the slag discharge trough 105 to prevent the grid frame from being blocked.

[0024] Reference Figure 1 , 2 4. Furthermore, the rotating dust-suppressing and humidifying mechanism consists of a servo motor A3, a rotating frame 301, an atomizing nozzle A302, a water tank A4, and a water pump A401.

[0025] A servo motor A3 is fixedly installed on the upper part of the inner wall of the feed inlet 101. The servo motor A3 is connected to a rotating frame 301 through an output shaft. The lower part of the rotating frame 301 is arranged in an arc shape. Several atomizing nozzles A302 are embedded below the rotating frame 301 and are arranged in a equidistant ring. A water tank A4 is located on the side of the hammer crusher 1. A water pump A401 is embedded in front of the water tank A4. The water tank A4, the water pump A401, and the several atomizing nozzles A302 are connected by a water guide hose. When the operator needs to crush a large amount of coking coal, the large amount of coal is poured into the feed inlet 101, and the water pump A401 is turned on to circulate water in the water tank A4. Atomized water is sprayed from several atomizing nozzles A302 at different angles through a water guiding hose. Then, the servo motor A3 is turned on to drive the rotating frame 301 to rotate clockwise half a turn and counterclockwise half a turn repeatedly. This drives the several atomizing nozzles A302 at different angles below to rotate clockwise half a turn and counterclockwise half a turn repeatedly, increasing the range of atomized water sprayed from the several atomizing nozzles A302 at different angles. This allows the sprayed atomized water to evenly contact the large amount of coal poured into the feed inlet 101. At the same time, it reduces the dust raised when the coal is poured into the feed inlet 101, while wetting a large amount of coal to avoid safety hazards during crushing. This improves the efficiency of dust reduction when a large amount of coal is poured into the feed inlet 101.

[0026] Reference Figure 1-3 Furthermore, the oscillating dust suppression mechanism consists of a movable frame B5, an atomizing nozzle B501, a movable rod 502, a servo motor B6, an eccentric wheel 601, a water tank B7, and a water pump B701.

[0027] Above the inner wall of the slag discharge tank 105, a movable frame B5 is rotatably arranged through a rotating shaft. There are several movable frames B5, which are arranged in equidistant parallel. An activity rod 502 is rotatably arranged between the movable frames B5 through a rotating shaft. A spray nozzle B501 is embedded below the movable frame B5. A servo motor B6 is fixedly installed above the inner wall of the slag discharge tank 105 near the side of one of the movable frames B5. The servo motor B6 is connected with an eccentric wheel 601 through an output shaft. A water tank B7 is arranged near the lower part of the water tank A4 on the side of the hammer crusher 1. A water pump B701 is embedded in front of the water tank B7. The water tank B7, the water pump B701 and several spray nozzles B501 are connected through a water guide hose. When a large amount of coal materials fall into the hammer crusher 1 in sequence, the staff turns on the servo motor supporting the electric crushing roller 103 to drive a number of crushing hammers 104 on the outer ring to rotate rapidly, so that a number of crushing hammers 104 rapidly strike the large coal materials. While the large coal materials are crushed, a large amount of dust will be raised by the coal materials being crushed in the hammer crusher 1. When the staff turns on the water pump B701 to spray atomized water from the several spray nozzles B501 through the water guide pipe, and then turns on the servo motor B6 to drive the eccentric wheel 601 to rotate, the eccentric wheel 601 continuously strikes the movable frame B5 to drive the activity rod 502 to swing repeatedly through the rotating shaft, and drives a number of spray nozzles B501 to swing repeatedly in a large range, increasing the spraying range of the atomized water, making the atomized water contact with the raised dust evenly in a large range, adsorbing and falling the dust, and carrying out efficient dust reduction treatment on the raised dust. At the same time, part of the atomized water contacts the coal materials being crushed again, humidifying the coal materials, avoiding the combustion of the coal materials caused by the friction during crushing, and making the slag and waste water generated by the coal materials being crushed pass through the grid network 102 and fall into the waste box 106 for collection. After the crushing is completed, the staff controls the two electric telescopic rods 109 to drive the baffle 108 to rotate through the rotating shaft, opens the discharge port 107 to make the crushed coal materials fall out from the discharge port 107 onto the surface of the leather conveyor belt 8, and the staff turns on the servo motor supporting the leather conveyor belt 8 to drive the supporting transmission roller to drive the leather conveyor belt 8 to transmit, and conveys the coal materials falling on the surface of the leather conveyor belt 8 to other processing sites, improving the effect of efficient dust reduction treatment on the dust raised during the crushing of the coal materials.

[0028] Refer to Figure 2 、 3 Further, the movable cleaning mechanism is composed of a screw rod slide rail 2, a sliding frame 201, a damping telescopic rod A202, a movable frame A203, an electric cleaning roller 204, a wire brush 205 and a damping telescopic rod B​​Inside the slag discharge trough 105, a screw slide rail 2 is fixedly installed on the side. A sliding frame 201 is slidably mounted on the side of the screw slide rail 2 via a slider. A damping telescopic rod A202 is fixedly installed on the side of the sliding frame 201, and a spring is fitted on the outer side of the damping telescopic rod A202. A movable frame A203 is rotatably mounted on the side of the end of the damping telescopic rod A202 via a rotating shaft. An electric cleaning roller 204 is rotatably mounted on the side of the movable frame A203 via a bearing. Several steel wire brushes 205 are fixedly mounted on the outer ring of the electric cleaning roller 204, arranged in an arc shape at equal intervals. The movable frame A203 and... A damping telescopic rod B206 is rotatably mounted on the side of the sliding frame 201, near the lower part of the damping telescopic rod A202, via a rotating shaft. A spring is fitted to the outer side of the damping telescopic rod B206. When a large amount of coal is being crushed, the operator opens two screw slide rails 2, causing the opposing sliding frame 201 to slide up and down repeatedly via a slider. Then, the servo motor of the electric cleaning roller 204 is activated, driving several steel wire brushes 205 on the outer ring of the electric cleaning roller 204 to rotate. This causes the electric cleaning roller 204 to move up and down repeatedly, simultaneously compressing the damping telescopic rod A202 and the damping telescopic rod B206, which, along with the outer spring, repeatedly extend and retract via the rotating shaft. The electric cleaning roller 204 repeatedly changes its angle to make extensive contact with the surface of the arc-shaped grid frame 102. The rotating electric cleaning roller 204 drives several steel wire brushes 205 on the outer ring to repeatedly scrape and clean the grid frame 102. This can prevent coal fragments and other materials from getting stuck inside the grid frame 102 and causing blockage, thus improving the efficiency of cleaning the grid frame 102.

[0030] Reference Figure 1-5 Furthermore, the leather conveyor belt 8, the electric crushing roller 103, and the electric cleaning roller 204 are all electrically connected to an external power source through the matching servo motors and the control panel of the hammer crusher 1. The electric telescopic rod 109, the lead screw slide rail 2, the servo motor A3, the water pump A401, the servo motor B6, and the water pump B701 are all electrically connected to an external power source through the control panel of the hammer crusher 1. Example

[0031] like Figure 3 , 6As shown, in addition to the embodiment in which several steel wire brushes 205 are fixedly installed around the outer ring of the electric cleaning roller 204 in an arc shape and arranged equidistantly, there is another embodiment in which several steel wire brushes 205 are fixedly installed around the outer ring of the electric cleaning roller 204 in a hook shape and arranged equidistantly. When the operator turns on the servo motor that is matched with the electric cleaning roller 204, it drives the several steel wire brushes 205 around the outer ring of the electric cleaning roller 204 to rotate, so that the electric cleaning roller 204 moves up and down repeatedly. At the same time, the damping telescopic rods A202 and B206 are squeezed and the outer spring is repeatedly extended and retracted through the rotating shaft. The electric cleaning roller 204 repeatedly changes its angle to make extensive contact with the surface of the arc-shaped grid frame 102. The rotating electric cleaning roller 204 drives a number of hook-shaped steel wire brushes 205 on the outer ring to perform efficient and repeated scraping and cleaning treatment within a larger area of ​​the grid frame 102. This can prevent coal fragments and other materials from getting stuck inside the grid frame 102 and causing blockage. Compared with the first embodiment, the cleaning effect is better.

[0032] Working principle: First, when workers need to crush a large amount of coal for coking, they pour the coal into the feed inlet 101 while simultaneously turning on the water pump A401. Water from the water tank A4 is then sprayed through the water hose from several atomizing nozzles A302 at different angles, creating atomized water. Next, the servo motor A3 drives the rotating frame 301 to rotate clockwise half a turn and counter-clockwise half a turn repeatedly, causing the atomizing nozzles A302 below to rotate clockwise half a turn and counter-clockwise half a turn repeatedly, increasing the atomization of the spray from the nozzles. The water sprayed into a wide area ensures that the atomized water evenly contacts the large amount of coal poured into the feed inlet 101, suppressing dust raised during the pouring process and wetting the coal to prevent safety hazards during crushing. Then, as the large amount of coal falls into the hammer crusher 1, the operator activates the servo motor of the electric crushing roller 103, causing several outer ring hammers 104 to rotate rapidly. This causes the hammers 104 to quickly strike large pieces of coal, crushing them while simultaneously releasing a large amount of coal inside the hammer crusher 1. The crushing of coal will generate a large amount of dust. Workers turn on water pump B701, which sprays water from water tank B7 through a water pipe onto several atomizing nozzles B501. Simultaneously, servo motor B6 is activated, driving eccentric wheel 601 to rotate. This causes eccentric wheel 601 to continuously strike movable frame B5, which in turn drives movable rod 502 to repeatedly swing via a rotating shaft. This causes the atomizing nozzles B501 to repeatedly swing over a wide range, increasing the spray area of ​​the atomized water and ensuring that the atomized water makes extensive and even contact with the dust, adsorbing and settling the dust, thus achieving efficient dust suppression. During the process, some of the atomized water comes into contact with the coal being crushed again, humidifying it and preventing combustion caused by friction during crushing. Finally, the operator opens the two lead screw slide rails 2, causing the opposing sliding frames 201 to slide up and down repeatedly via the slider. Then, the servo motor of the electric cleaning roller 204 is turned on, causing several steel wire brushes 205 on the outer ring of the electric cleaning roller 204 to rotate. As the electric cleaning roller 204 moves up and down repeatedly, it compresses the damping telescopic rods A202 and B206, which, along with the outer spring, repeatedly extend and retract via the rotating shaft. The electric cleaning roller 204 repeatedly changes its angle to make extensive contact with the surface of the arc-shaped grid frame 102. The rotating electric cleaning roller 204 drives several steel wire brushes 205 on the outer ring to repeatedly scrape and clean the grid frame 102. The slag and wastewater generated by the crushed coal pass through the grid frame 102 and fall into the waste bin 106 for collection. After crushing is completed, the operator controls two electric telescopic rods 109 to drive the baffle 108 to rotate through the rotating shaft, opening the discharge port 107 so that the crushed coal falls from the discharge port 107 onto the surface of the leather conveyor belt 8. The operator then turns on the servo motor of the leather conveyor belt 8 to drive the transmission roller to drive the leather conveyor belt 8 to transport the coal that has fallen on the surface of the leather conveyor belt 8 to other processing sites.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
