Description

Technical Field

[0001] The utility model belongs to the technical field of dust cleaning for conveyor corridors, in particular to a dust cleaning device for belt conveyor corridors. Background Art

[0002] At present, the material transfer within steel enterprises is mostly completed by belt conveyors. A belt conveyor corridor is set above the ground between the two workshops. During the material transfer process, the corridor has the problem of dust accumulation and is difficult to clean.

[0003] Because materials may be scattered during transportation on the belt conveyor in the corridor, and materials brought back by the return belt surface of the belt conveyor may also be scattered on the floor of the corridor; therefore, there is usually a large amount of scattered materials on both sides of the belt conveyor inside the corridor.

[0004] like Figure 7 As shown, with the increasingly stringent environmental protection requirements, the belt surface of the belt conveyor in the corridor is closed by a sealing cover (the purpose is to reduce the dust from spilling into the air), so it is difficult for on-site workers to use shovels to send the dust and scattered materials in the corridor back to the belt surface, making cleaning difficult.

[0005] A belt corridor cleaning device described in publication number CN210674604U utilizes a negative pressure mechanism to absorb fallen materials and dust for cleaning. Some of the scattered materials on the corridor floor are relatively large in particles, approximately 1-10 cm, while others are fine dust accumulations. The dust accumulations can be cleaned by negative pressure vacuuming equipment, but the larger particles need to be manually cleaned and collected using tools such as shovels for reuse. Moreover, the scattered materials after cleaning cannot be automatically re-conveyed after recovery, and need to be manually re-conveyed, which is time-consuming and labor-intensive.

The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example

[0035] like Figures 1 to 3 As shown, a belt conveyor corridor cleaning device described in this embodiment includes a feeding mechanism 13 for feeding recycled materials to the belt conveyor 3, and also includes a pusher for pushing the scattered materials along the corridor of the belt conveyor 3 to the feeding mechanism 13, and the pusher includes a mobile trolley, on which a dust box 10 and a collection mechanism 12 are installed;

[0036] like Figure 6 As shown, the feeding mechanism 13 includes a feeding box 131 of an inverted "U"-shaped structure, one side of the feeding box 131 is arranged opposite to the pusher, and the other side is provided with a through chute 135 for discharging materials, and a collection trough 15 for collecting the materials pushed by the pusher is provided at the lower end of the feeding box 131. The collection trough 15 is a "U"-shaped structure, and a conveying component for conveying the materials in the collection trough 15 to the through chute 135 is installed in the feeding box 131;

[0037] like Figure 5 As shown, the collecting mechanism 12 includes a pushing plate 127 for pushing the scattered material to the collecting trough 15, the pushing plate 127 is installed on the moving trolley, and a dust collecting component is arranged above the pushing plate 127 for absorbing the dust generated when the pushing plate 127 pushes the material into the dust collecting box 10;

[0038] A crushing assembly for crushing large particles of scattered materials is provided between the dust suction assembly and the push plate 127 .

[0039] When cleaning the scattered materials, the scattered materials are pushed along the corridor of the belt conveyor 3 to the feeding mechanism 13 by the pusher. During the pushing process, dust can be sucked by the dust suction component, and large particles can be crushed by the impact component (the large particles mainly refer to large particles larger than 10 cm); when the scattered materials reach the feeding mechanism 13, the materials are collected by the collecting trough 15, and finally the materials in the collecting trough 15 are conveyed to the through chute 135 by the conveying component and discharged from the through chute 135.

[0040] This embodiment further illustrates the technology of the mobile car. Figure 3 As shown, the mobile trolley includes a horizontally arranged carrying plate 6, and a plurality of rollers 7 are installed at the bottom of the carrying plate 6 to facilitate the movement of the carrying plate 6. Figure 1 and Figure 2 The front side of Figure 3 The dust box 10 and the collecting mechanism 12 are installed on the carrying plate 6. The mobile trolley of this design has a simple structure, and other trolleys can also be used in practical applications.

[0041] like Figure 5 As shown, this embodiment further illustrates the technology of the dust collection component, which includes a negative pressure dust collector 121, which is installed on a mobile trolley, and the dust outlet of the negative pressure dust collector 121 is connected to the dust box 10 through a dust conveying pipe 122 (specifically, a third hole 11 is opened on the dust box 10, and the dust conveying pipe 122 is installed at the third hole 11, and the third hole 11 can be a rubber tube); a dust collection plate 124 is arranged above the pushing plate 127, and a dust collection groove 125 is opened in the dust collection plate 124, and a plurality of dust collection ports 126 communicating with the dust collection groove 125 are opened on the dust collection plate 124 located in the direction of the pushing plate 127, and the dust inlet of the negative pressure dust collector 121 is connected to the dust collection pipe 123, and the dust inlet of the dust collection pipe 123 passes through the dust collection plate 124 and communicates with the dust collection groove 125 (in order to facilitate the fixing of the dust collection pipe 123, as shown in FIG. Figure 3 As shown, it is preferred that a fixing plate is vertically fixed on the supporting plate 6, a second hole 9 is provided on the fixing plate, and the dust suction pipe 123 is installed in the second hole 9).

[0042] When the dust collection assembly is installed on the aforementioned mobile trolley, the negative pressure dust collector 121, the dust collection box 10, the dust collection plate 124 and the push plate 127 are correspondingly installed on the carrying plate 6. In order to further ensure that the spilled material is cleaned up, Figure 3As shown, it is preferred that the lower surface of the push plate 127 and the lower surface of the roller 7 are on the same horizontal plane. If an existing mobile cart is used, this part can be referred to and will not be described in detail here.

[0043] This embodiment further illustrates the technology of breaking the components. Figure 5 As shown, the smashing assembly includes an electric telescopic device 128, and a strike push plate 129 is fixed to the telescopic end of the electric telescopic device 128 for striking and cooperating with the side wall of the loading box 131. The design is simple in structure and other existing smashing assemblies can also be used in application.

[0044] When in use, the electric telescopic device 128 is rapidly extended and retracted back and forth, thereby driving the impact push plate 129 to extend and retract. During the pushing process, a certain impact can be achieved through the speed difference between the large particles and the impact push plate 129. At this time, a part of the large particle material will be crushed, and a part of the uncrushed material will continue to be pushed. Finally, after being pushed between the feeding box 131 and the impact push plate 129, with the cooperation of the feeding box 131, the impact push plate 129 will impact the material. At this time, the feeding box 131 blocks the material and accelerates the impact effect of the material. When in use, if there are not many scattered large particle materials, the material can be directly pushed between the feeding box 131 and the impact push plate 129, and then the electric telescopic device 128 can be started. The electric telescopic device 128 can also be a cylinder or a hydraulic cylinder.

[0045] In order to facilitate the installation of the electric telescopic device 128, it is preferred that the electric telescopic device 128 is installed on the push plate 127. Figure 3 or Figure 5 As shown, the push plate 127 is a horizontally placed “L”-shaped structure, and the electric telescopic device 128 is installed on the vertical surface of the push plate 127 .

[0046] This embodiment further illustrates the technology of the conveying assembly. Figure 6 As shown, the conveying assembly includes a belt conveyor 133, which is installed in the loading box 131 through a fixed plate 132 (during the specific installation, the fixed plates 132 are two pieces and are "U"-shaped structures, and the belt conveyor 133 is installed between the two fixed plates 132). The belt surface of the belt conveyor 133 is parallel to the two inner side walls of the loading box 131, and a number of inclined inclined plates 134 are fixed along the belt winding direction. Preferably, the inclined plates 134 are evenly distributed, and the inclination directions of all inclined plates 134 are consistent. One end of the belt conveyor 133 is located in the loading box 131, and the other end is located in the collecting trough 15. When in use, the conveying assembly can also use a conveyor of the prior art such as an auger. During transportation, such as Figure 6As shown, the belt conveyor 133 is started, the belt rotates clockwise, and the material is dug on the belt through the inclined plate 134. When passing through the through inclined slot 135, the material is discharged from the through inclined slot 135. In order to improve the conveying efficiency, it is preferred that the inclined plate 134 moves along the inner wall of the loading box 131.

[0047] This embodiment further illustrates the technology, in order to improve the dust collection effect, such as Figure 5 As shown, the dust collecting plate 124 is a groove-shaped structure with the groove opening facing downward, wherein the groove wall in the material pushing direction is inclined with a narrow groove bottom and a wide groove opening.

[0048] This embodiment further illustrates the technology. A material collecting box 136 is provided corresponding to the through chute 135. A material collecting port for collecting the material discharged from the through chute 135 is provided on the material collecting box 136. An auger conveyor for conveying the material in the auger conveyor 131 to the belt conveyor 3 is provided corresponding to the loading box 131. This design can automatically realize material recovery. The auger conveyor is also called a screw conveyor. Figure 3 As shown, its structure mainly includes a feeding tube 137, a feeding screw is provided in the feeding tube 137, and the feeding screw is connected to a driving motor 138 through a belt.

[0049] This embodiment further illustrates the technology. A sealing cover 4 is provided above the belt conveyor 3. The auger conveyor passes through the sealing cover 4 to convey materials to the belt conveyor 3. During installation, a first hole 5 is opened on the sealing cover 4, and the discharge end of the feeding pipe 137 is installed at the first hole 5 on the sealing cover 4 above the belt conveyor 3.

[0050] In order to facilitate the collection of materials, Figure 4 As shown, a feed trough 14 is provided on the feed box 131 near the push plate 127, and a filter screen 16 is embedded in the feed trough 14. When in use, the material can enter the collection trough 15 through the feed trough 14. The filter screen 16 in this embodiment can isolate large particles of scattered materials larger than 10 cm, and scattered materials smaller than 10 cm can normally enter the collection trough 15 through the feed trough 14. During installation, the feed trough 14 can also be provided on the collection trough 15, or a portion of grooves can be provided on both the collection trough 15 and the feed box 131, and the whole is combined into the feed trough 14. The specific situation can be determined according to the installation environment.

[0051] In this embodiment, the collecting trough 15 is installed in the corridor floor 1 as a whole, which is convenient for material collection. Figure 1 As shown, considering that the existing belt conveyor 3 is basically installed in the middle of the corridor wall 2, there will be material spillage on both sides of the belt conveyor 3, so the pusher and feeding mechanism 13 in the above scheme are both used in two sets. Figure 2As shown, considering the situation that there is a wide distance between the belt conveyor 3 and the corridor wall 2, it is preferred that there are two sets of collecting mechanisms 12, and the dust box 10 is installed between the collecting mechanisms 12.

[0052] When the above scheme collects materials, the push handle 8 is pushed to move the carrying plate 6 and the dust box 10 thereon and the collecting mechanism 12 under the action of the roller 7. During the movement, the pushing plate 127 on the collecting mechanism 12 will push the scattered materials on the corridor floor to the upper feeding mechanism 13. During the pushing process, the negative pressure vacuum cleaner 121 is operated to pass the dust accumulation generated during the pushing of the scattered materials into the dust suction groove 125 through the dust suction port of the dust suction plate, and then enter the dust collection box through the dust suction pipe 123 and the dust conveying pipe 122. In this way, dust can be avoided and a good working environment can be maintained. When the scattered materials are pushed to the discharge trough 14, the filter screen plate 16 can isolate large particles of scattered materials larger than 10 cm, and scattered materials below 10 cm including 10 cm can normally pass through the discharge trough 14 into the collecting trough 15, while scattered materials larger than 10 cm are crushed into small particles by controlling the electric telescopic device 128 to impact the pushing plate 129.

[0053] When the above scheme is used for loading, the belt conveyor 133 inside the loading box 131 on the loading mechanism 13 is controlled to rotate clockwise, which will drive the inclined plate 134 fixed on the belt conveyor 133 to move synchronously, so that the scattered material collected in the collecting trough 15 is transported counterclockwise under the action of the belt conveyor 133 and the inclined plate 134. When the inclined plate 134 holding the scattered material moves to the same straight line as the bottom end of the through-type chute 135, the scattered material will fall into the collecting box 136 through the through-type chute 135, and then the driving motor 138 is controlled to drive the feeding screw in the loading pipe 137 to transfer the scattered material to the belt conveyor, so that the scattered material can be re-transported, and the labor force is reduced and the work efficiency is improved.
