[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0033] Reference Figure 1-Figure 6As shown, a coal powder distribution device of the present invention comprises: a conveyor 1, a feed barrel 13, a filter screen 22, and a collecting box 14; specifically, the conveyor 1 comprises a bracket and a conveyor belt mounted on the bracket; a pair of pads 11 are symmetrically arranged on both sides of the conveyor belt; an interception frame 12 is arranged at the top of the pad 11, and the interception frame 12 comprises a pair of isolation parts 121 and an interception part 122 fixedly connected to the pair of isolation parts 121, and the pair of isolation parts 121 are respectively fixedly connected to the top of the pair of pads 11; the feed barrel 13 is located directly above the interception frame 12; the filter screen 22 is provided with a plurality of filters located inside the interception frame 12; isolation strips 23 are fixedly connected between the plurality of filter screens 22, and the plurality of isolation strips 23 cooperate with the plurality of filter screens 2 2 forms an annular structure; a partition 24 is arranged on the side of the isolation strip 23, and the partition 24 points to the outside of the annular structure, and a pair of partitions 24 are respectively slidably connected with the side of a pair of isolation parts 121; a pair of support shafts 2 are rotatably arranged between the pair of isolation parts 121, and the installation height of the support shaft 2 close to the interception part 122 is lower than the installation height of the support shaft 2 far away from the interception part 122; a pair of rotating belts 21 are installed on the surface of the pair of support shafts 2, and the pair of rotating belts 21 are respectively fitted with the side of the pair of isolation parts 121; a plurality of filter screens 22 are evenly fixed between the pair of rotating belts 21; the collection box 14 is fixed between the pair of isolation parts 121, and the box opening of the collection box 14 is located directly below the support shaft 2 far away from the interception part 122;

[0034] In the coal preparation operation, there are multiple coal storage towers, which can also be called coal storage bins, in the coal yard. Different types of coal powder are transported to different coal storage towers for standby use through belt conveyors, and then transported to a crushing device for crushing during the coal blending operation through a conveyor. After the coal is crushed into coal powder, it is necessary to distribute the coal powder to the coal blending bin. Specifically, when the coal is distributed, the crushed coal powder needs to be transported to the coal blending bin through a conveyor. However, in the actual crushing process, large particles of coal powder will remain in the coal powder, and in the coal preparation process, coal powder of different particle sizes needs to be distributed in different areas. Therefore, in the distribution operation, large particles in the coal powder need to be removed. The current distribution device is difficult to effectively remove large particles of coal powder in the coal powder, and filtering is required before distribution, which increases the operation process and reduces the distribution efficiency. In order to solve the above problems, an embodiment of the present invention can be adopted. Specifically, first, the conveyor 1 is started, and the conveyor 1 controls the conveyor belt to operate. The operation direction is as follows: Figure 1As shown by the arrow; at the same time, the crushed coal powder is conveyed into the feed barrel 13 through the conveying device, and the conveying device here can be a spiral feeder; the crushed coal powder will be discharged downward through the feed barrel 13; at the same time, the output motor external to the support shaft 2 is started, and the support shaft 2 drives the rotating belt 21 to rotate counterclockwise, and the rotating belt 21 drives the filter screen 22 and the isolation strip 23 to rotate synchronously, and the coal powder discharged downward from the feed barrel 13 falls onto the surface of the filter screen 22. Since the height of the support shaft 2 close to the intercepting portion 122 is lower than that of the support shaft 2 far away from the intercepting portion 122, and the filter screen 22 moves from bottom to top, the coal powder will pass through the filter screen 22 and fall downward between a pair of pads 11, and finally fall into the moving The large particles of coal powder in the coal powder are transported and moved on the conveyor belt, while the large particles of coal powder in the coal powder are blocked by the partition 24 to prevent them from rolling down along the filter screen 22. When the support shaft 2 moves to the position away from the interception part 122, the large particles of coal powder fall downward into the collecting box 14, while the coal powder falls downward onto the conveyor belt through the filter screen 22, so that the coal powder and the large particles of coal powder are separated, and there is no need to add a filtering process in advance, which improves the efficiency of coal powder distribution. In addition, when the coal powder falls onto the conveyor belt and moves, it needs to pass through the interception part 122 of the interception frame 12. The interception part 122 will limit the stacking height of the coal powder on the conveyor belt, and prevent the coal powder on the conveyor belt from being stacked too high, so that it will splash under the action of air resistance when moving.

[0035] It should be pointed out that when designing the rotation speed of the support shaft 2 during the filtration process of the coal powder in the technical solution of the present invention, it is necessary to consider leaving enough time for the filter screen 22 to filter the coal powder to avoid a large amount of coal powder being transported into the collection box 14.

[0036] Reference Figure 2-Figure 4As shown, when the feed barrel 13 drops downward, there is a situation where the coal powder carrying large particles directly passes through the gap between the rotating belt 21 and the intercepting portion 122 and falls downward onto the conveyor belt. For this reason, the embodiment of the present invention also includes: a blocking plate 4, specifically, the blocking plate 4 is arranged between the intercepting portion 122 and the rotating belt 21, the bottom end of the blocking plate 4 is fixedly connected to the top end of the pad 11, and the top end of the blocking plate 4 is in contact with the boundary of the bottom end of the feed barrel 13 close to the intercepting portion 122. The blocking plate 4 can prevent the coal powder discharged from the bottom end of the feed barrel 13 from falling from the gap between the rotating belt 21 and the intercepting portion 122; the blocking plate 4 is arranged, and the blocking plate 4 is made of elastic plastic; initially, the blocking plate 4 is attached to the filter The mesh 22 and the surface of the rotating belt 21; the partition 24 is made of elastic material; therefore, the coal powder falling downward from the feed barrel 13 is isolated by the blocking plate 4 to the surface of the filter mesh 22, preventing the coal powder from falling from the gap between the rotating belt 21 and the intercepting portion 122; and when the rotating belt 21 drives the filter mesh 22 to rotate, the filter mesh 22 drives the partition 24 to rotate synchronously through the isolation strip 23, and when the partition 24 contacts the blocking plate 4, the partition 24 and the blocking plate 4 are deformed at the same time, and the partition 24 can pass through the blocking plate 4 smoothly, and the end of the partition 24 will generate a certain vibration when scraping the side of the blocking plate 4, causing the filter mesh 22 to vibrate synchronously, thereby improving the smoothness of the coal powder passing through the filter mesh 22.

[0037] Reference Figure 4-Figure 5As shown, if the recovered large-particle coal powder is stored in the collection box 14 for a long time, it will eventually cause the coal powder in the collection box 14 to overflow and fall, thereby affecting the consistency of the coal powder distribution. For this reason, the embodiment of the present invention also includes: a rolling roller 141 and an inclined plate 144; specifically, the rolling roller 141 is arranged inside the collection box 14, and a driven gear 142 is arranged at the end of the rolling roller 141, and a driving gear 143 is sleeved on the surface of the support shaft 2, and the driving gear 143 and the driven gear 142 are meshed with each other; a receiving notch 10 is provided on the side of the isolation portion 121 facing the rotating belt 21, and the driving gear 143 and the driven gear 142 are arranged inside the receiving notch 10; the bottom end of the inclined plate 144 is fixedly connected to the inner bottom wall of the collection box 14, and the inclined surface of the inclined plate 144 is located at the top and the inclined surface of the inclined plate 144 is in contact with the annular circumferential surface of the rolling roller 141; a blanking port 145 is provided at the end of the inclined plate 144 away from the rolling roller 141, and the blanking port 145 is provided The opening 145 passes through the bottom end of the collecting box 14 and the rolling roller 141 is located between the dropping opening 145 and the support shaft 2; when in use, the support shaft 2 drives the driving gear 143 to rotate, and the driving gear 143 drives the driven gear 142 meshing therewith to rotate synchronously, and the driven gear 142 drives the rolling roller 141 in the collecting box 14 to rotate, and the large particles of coal powder that fall into the collecting box 14 are located at the top of the inclined plate 144 and at one side of the rolling roller 141, specifically at the side of the inclined plate 144 with a higher position, and the inclined surface of the inclined plate 144 is located at the top, so the large particles of coal powder will slide downward, and when passing through the rotating rolling roller 141, since the inclined surface of the inclined plate 144 contacts the rolling roller 141, the large particles of coal powder passing through the rolling roller 141 are rolled into pulverized coal, and then fall downward through the dropping opening 145 onto the conveyor belt, and are synchronously transported by the conveyor belt, so as to realize the secondary crushing and recovery of the large particles of coal powder; there is no need to crush them again afterwards; it is beneficial to the coal powder distribution process.

[0038] Reference Figure 4-Figure 5 As shown, large particles of coal powder falling through the filter screen 22 may fall to the inclined plate 144 located below the rolling roller 141, making it difficult for the rolling roller 141 to roll over the large particles of coal powder. For this reason, an embodiment of the present invention also includes: a baffle 146. Specifically, both ends of the baffle 146 are fixedly connected to the side surfaces of a pair of isolation portions 121, and the bottom end of the baffle 146 is slidably connected to the annular circumferential surface of the rolling roller 141. When the rolling roller 141 rotates, the bottom end of the baffle 146 will scrape off the coal powder attached to the surface of the rolling roller 141, and the baffle 146 will block the large particles of coal powder falling from the filter screen 22, ensuring that the large particles of coal powder fall to a position where they can pass through the rolling roller 141.

[0039] Reference Figure 4-Figure 7As shown, during use, in order to improve the filtering speed of the filter 22 for coal powder, ensure the filtering efficiency of the coal powder, and prevent large particles of coal powder from clogging the filter 22, the embodiment of the present invention also includes: a rotating shaft 3 and a first bracket 32; specifically, the rotating shaft 3 is provided with a pair and is rotatably arranged between a pair of isolation parts 121, and the rotating shaft 3 passes through the internal area of ​​the rotating belt 21; a pair of first brackets 32 are fixedly connected to the center position of the surface of the rotating shaft 3, and a drop plate 31 is fixedly connected to the bottom end of the rotating shaft 3; when the rotating belt 21 drives the filter 22 to rotate, the filter 22 drives the isolation strip 23 to rotate synchronously, and during the movement of the isolation strip 23, the drop plate 31 on the surface of the rotating shaft 3 will be intermittently squeezed and swung by the isolation strip 23, so that the rotating shaft 3 drives the first bracket 32 ​​to reciprocate, and the first bracket 32 ​​will intermittently hit the filter 22 when reciprocating, so that the filter 22 vibrates, thereby accelerating the filtration of coal. The first bracket 32 ​​will not hinder the rotation of the isolation bar 23; it should be noted that when the first bracket 32 ​​intermittently hits the filter screen 22, the first bracket 32 ​​itself will also vibrate, so the coal powder falling on the first bracket 32 ​​will not gather and accumulate, and the coal powder will pass through the filter screen 22 smoothly; in addition, the oscillation of the filter screen 22 can prevent large particles of coal powder from clogging the filter screen 22, ensuring that the coal powder passes through the filter screen 22 smoothly, and the rotation speed of the filter screen 22 is controlled, and the discharge speed of the feed barrel 13 is controlled, so the fluctuation of the coal powder falling on the conveyor belt of the conveyor 1 per unit time will not be too large, and the uniform conveying and distribution of the coal powder can be achieved.

[0040] Reference Figure 4-Figure 7 As shown, during use, coal powder may fall between the rotating belt 21 and the isolation portion 121. When a large amount of coal powder gathers between the rotating belt 21 and the isolation portion 121, it will affect the rotation stability of the rotating belt 21. For this reason, an embodiment of the present invention also includes: a second bracket 33; specifically, the second bracket 33 is symmetrically installed on the surface of the rotating shaft 3 based on the center of the rotating shaft 3, and is located in the internal area of ​​the rotating belt 21; when the rotating shaft 3 reciprocates, the second bracket 33 will intermittently squeeze the portion of the rotating belt 21 close to the isolation portion 121, and is located between the partitions 24, so that the rotating belt 21 is intermittently deformed, that is, the portion of the rotating belt 21 close to the isolation portion 121 is tilted toward the filter screen 22, so that the coal powder on the rotating belt 21 is driven to concentrate in the direction of the filter screen 22, which is beneficial to the process of the coal powder passing through the filter screen 22.

[0041] Reference Figure 8As shown, when the feed barrel 13 discharges the coal powder downward, the coal powder is concentrated at one point of the filter screen 22, which will affect the filtering efficiency of the filter screen 22. For this reason, the embodiment of the present invention also includes: a gear ring 131 and a stirring piece 132; specifically, the gear ring 131 is rotatably connected to the bottom end of the feed barrel 13, and the side of the gear ring 131 is meshingly connected with a driving gear 133; a plurality of stirring pieces 132 are fixedly connected to the bottom end of the gear ring 131; it should be noted that the driving gear 133 is externally connected to a driving motor, and when the feed barrel 13 discharges the coal powder downward, the driving motor drives the driving gear 133 to rotate, the driving gear 133 drives the gear ring 131 to rotate, the gear ring 131 drives the stirring piece 132 to rotate, and the stirring piece 132 will move the coal powder falling from the feed barrel 13 to the surroundings, further driving the coal powder to fall evenly onto the filter screen 22, thereby improving the filtering efficiency of the coal powder.

[0042] Reference Figure 9-11 As shown, when the coal powder is transported through the conveyor belt, in order to avoid the coal powder on the conveyor belt falling off due to air resistance, the embodiment of the present invention also includes: a coating roller 5 and a winding roller 6; specifically, the coating roller 5 is arranged on one side of the interception frame 12 and does not squeeze the conveyor belt in the conveyor 1, and is away from the isolation portion 121 of the interception frame 12; a film is wrapped around the surface of the coating roller 5; a connecting component 51 is arranged at the end of the coating roller 5, and the connecting component 51 is installed on the bracket of the conveyor 1; the winding roller 6 is arranged on the conveyor 1 and is located at the end of the conveyor 1 for unloading, and a film released from the coating roller 5 is wrapped around the surface; a connecting component 2 61 is arranged at the end of the winding roller 6, and the connecting component 2 61 is installed on the bracket of the conveyor 1; it should be noted that a control motor is arranged at the end of the winding roller 6, and the control motor is installed on the bracket of the conveyor 1; the winding roller 6 passes The mounting plate is rotatably arranged on the connecting component 2 61; a feeding motor is arranged at the end of the coating roller 5, and the feeding motor is installed on the bracket of the conveyor 1; when the conveyor belt moves out from the intercepting portion 122 of the intercepting frame 12, the feeding motor starts to drive the coating roller 5 to rotate, and the film wrapped on the surface of the coating roller 5 covers the surface of the conveyor belt, and is then wound up by the winding roller 6, which is driven by the control motor, and the winding roller 6 is located at the unloading end of the conveyor 1; when the coal powder moves with the conveyor belt, the film moves synchronously, and the film will not move relative to the coal powder on the conveyor belt. The covering of the film during the coal powder transportation avoids the obstruction of the air on the conveyor belt during the movement, causing the coal powder to fly up and fall off the conveyor belt, thereby improving the stability and integrity of the coal powder during the transportation process; it should be pointed out that, initially, the film on the coating roller 5 is at the same height as the bottom end of the intercepting portion 122; therefore, the coal powder on the conveyor belt will not be squeezed.

[0043] In the process of the coating roller 5 releasing the film and the winding roller 6 winding the film, the overall diameter of the coating roller 5 gradually decreases, while the overall diameter of the winding roller 6 gradually increases, in order to avoid the film from tilting and affecting the use effect; the embodiment of the present invention arranges a first hydraulic cylinder and a second hydraulic cylinder; the specific connecting component 1 51 is specifically the first hydraulic cylinder; the connecting component 2 61 is specifically the second hydraulic cylinder; when in use, as the coating roller 5 releases the film and the winding roller 6 winds up the film, the first hydraulic cylinder and the second hydraulic cylinder respectively drive the coating roller 5 to move downward and the winding roller 6 to move upward, so that the film is always horizontally covered on the coal powder on the conveyor belt, avoiding the change of the overall diameter of the coating roller 5 and the winding roller 6 affecting the use effect of the film.

[0044] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
