Description

Technical Field

[0001] This utility model belongs to the field of dust suppression technology for belt conveyors, and specifically refers to a guide trough with a bidirectional dust suppression buffer chamber. Background Technology

[0002] The material discharge point at the tail end of a belt conveyor requires sealing of the guide chute to prevent material and dust leakage. Current technology typically uses fully enclosed guide chutes and the traditional standard guide chutes from the DTII belt conveyor selection manual. However, fully enclosed guide chutes and traditional standard guide chutes present the following serious problems:

[0003] (1) The fully enclosed guide chute is designed to completely wrap the belt, making it inconvenient to replace idlers, pallets and other auxiliary equipment of the belt conveyor, and making maintenance very difficult.

[0004] (2) Because the fully enclosed material guide chute needs to completely wrap the belt, the corner will inevitably form material that is difficult to clean. When the material leaks, it will generate dust and pose a safety hazard.

[0005] (3) Fully enclosed material guide troughs are expensive and have low cost-effectiveness;

[0006] (4) The flow area of ​​the traditional standard guide chute is small, which causes the material to squeeze the skirt plate, greatly reducing the service life of the skirt plate and requiring frequent replacement and maintenance of the skirt plate in the later stage.

[0007] (5) Traditional standard feed troughs cannot meet the dust reduction function due to their small flow area.

[0008] The above problems are currently prevalent in the conveying processes of belt conveyors in scenarios such as large docks, thermal power plants, and iron smelting plants. Utility Model Content

[0009] The main purpose of this utility model is to provide a material guide trough with a bidirectional dust suppression buffer chamber, which solves the problems existing in the prior art, has a larger flow area, and a longer service life of the skirt plate, thereby reducing the later operating costs.

[0010] To achieve the above objectives, the solution of this utility model is:

[0011] A material guide chute with a bidirectional dust suppression buffer chamber includes several material guide units. Each material guide unit includes a longitudinal material guide cavity disposed above the belt of a conveyor belt, and two transverse material guide cavities disposed on both sides of the longitudinal material guide cavity. The longitudinal material guide cavity is formed by several sealing plates, and a gap is reserved between the lower edge of the sealing plates on the left and right side walls of the longitudinal material guide cavity and the belt. An mounting plate is installed on the outer wall of the longitudinal material guide cavity, and a skirt is fixed on the mounting plate. The lower edge of the skirt abuts against the upper surface of the belt. The transverse material guide cavity is formed by the outer wall of the longitudinal material guide cavity, the mounting plate, and the skirt. The transverse material guide cavity communicates with the longitudinal material guide cavity through the gap.

[0012] The skirt abuts against the upper surface of the left or right edge of the belt.

[0013] Preferably, the mounting plate includes a first connecting portion connected to the outer wall of the longitudinal guide cavity, and a second connecting portion for connecting the skirt plate, wherein the first connecting portion and the second connecting portion form an angle of less than 90°; the skirt plate includes a third connecting portion fitted to and connected to the inner wall of the second connecting portion, and a sealing portion integrally formed on the lower edge of the third connecting portion, wherein the sealing portion is fitted to the upper surface of the belt to achieve surface contact, and the third connecting portion and the sealing portion form an angle of greater than 90°.

[0014] Preferably, the edge of the mounting plate that connects to the outer wall of the longitudinal guide cavity is provided with a plurality of waist holes, which are used to adjust the installation position of the mounting plate and the skirt plate.

[0015] Preferably, the outer wall of the sealing plate is provided with a screw for the waist hole to be fitted, and a nut is used to fit on the screw to fix the upper edge of the mounting plate.

[0016] Preferably, the screw is a bolt that passes through the sealing plate.

[0017] Both the sealing plate and the mounting plate are made of metal.

[0018] The sealing plate has folded edges, and adjacent folded edges are locked together by bolts and nuts; the longitudinal guide cavity is fixed on the frame of the belt conveyor, and the folded edges are locked to the frame and the mounting plate is locked to the folded edges by bolts and nuts.

[0019] The skirt panel is made of a special polymer material.

[0020] The feed trough with bidirectional dust suppression buffer chamber also includes a feed pipe connected to the upper surface of one of its longitudinal feed chambers.

[0021] After adopting the above technical solution, the present invention has the following technical effects:

[0022] The material guide trough of this utility model consists of a longitudinal material guide cavity and a transverse material guide cavity, which can increase the flow area of ​​the guide trough by about 38% compared with the traditional structure. The expansion design of the longitudinal and transverse dust suppression buffers can reduce the induced wind speed inside the material guide trough, thereby reducing the amount of dust. Among them, the design of the transverse material guide cavity allows the traditional skirt plate installation position to be moved outward, which not only increases the cross-sectional area of ​​the material guide trough, but also reduces the direct contact between the material conveyed by the belt conveyor and the skirt plate, thereby improving its service life. The coverage area of ​​the material guide trough is only located on the upper surface of the belt of the belt conveyor, without covering its idler rollers, idler plates, etc., making the auxiliary equipment of the belt conveyor easier to inspect and maintain.

[0036] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0037] refer to Figure 1-3As shown, this utility model discloses a guide trough with a bidirectional dust suppression buffer chamber, including several guide units 10 that can be spliced ​​into a guide trough to cooperate with the belt 20 of the conveyor belt for dust suppression. Each guide unit 10 includes a longitudinal guide cavity 101 disposed above the belt 20, and two transverse guide cavities 102 respectively disposed on both sides of the longitudinal guide cavity 101.

[0038] The longitudinal guide cavity 101 is formed by several sealing plates 1, and a gap 30 is reserved between the lower edge of the sealing plates 1 on the left and right side walls of the longitudinal guide cavity 101 and the belt 20.

[0039] An installation plate 2 is installed on the outer wall of the longitudinal guide cavity 101. A skirt plate 3 is fixed on the installation plate 2. The lower edge of the skirt plate 3 abuts against the upper surface of the belt 20. The outer wall of the longitudinal guide cavity 101, the installation plate 2 and the skirt plate 3 enclose and form a transverse guide cavity 102. The transverse guide cavity 102 is connected to the longitudinal guide cavity 101 through a gap 30.

[0040] Through the above scheme, the material guide trough of this utility model is composed of a longitudinal material guide cavity 101 and a transverse material guide cavity 102, which can increase the flow area of ​​the guide trough by about 38% compared with the traditional structure. In addition, the expansion design of the longitudinal and transverse dust suppression buffers can reduce the induced wind speed inside the material guide trough, thereby reducing the amount of dust. Among them, the design of the transverse material guide cavity 102 allows the traditional skirt plate installation position to be moved outward, which not only expands the cross-sectional area of ​​the material guide trough, but also reduces the direct contact between the material conveyed by the belt conveyor and the skirt plate 3, thereby improving its service life. The coverage area of ​​the material guide trough is only located on the upper surface of the belt 20 of the belt conveyor, without covering its idler rollers, pallets, etc., making the auxiliary equipment of the belt conveyor easier to inspect and maintain.

[0041] The following are specific embodiments of the present invention.

[0042] Specifically, the skirt 3 is abutted against the upper surface of the left or right edge of the belt 20.

[0043] Furthermore, the aforementioned mounting plate 2 includes a first connecting portion 21 connected to the outer wall of the longitudinal guide cavity 101, and a second connecting portion 22 for connecting the skirt plate 3. The first connecting portion 21 and the second connecting portion 22 form an angle of less than 90°. The skirt plate 3 includes a third connecting portion 31 that adheres to and connects to the inner wall of the second connecting portion 22, and a sealing portion 32 integrally formed on the lower edge of the third connecting portion 31. The sealing portion 32 adheres to the upper surface of the belt 20 to achieve surface contact, and the third connecting portion 31 and the sealing portion 32 form an angle of greater than 90°. Through the surface contact between the sealing portion 32 of the skirt plate 3 and the belt 20, it can be ensured that the skirt plate 3 fits the belt 20 sufficiently to prevent dust leakage and damage to the belt.

[0044] Secondly, the edge (i.e. the first connecting part 21) where the mounting plate 2 connects to the outer wall of the longitudinal guide cavity 101 is provided with a number of waist holes 23. The waist holes 23 are used to adjust the installation position of the mounting plate 2 and the skirt plate 3 so as to ensure that the skirt plate 3 fits the upper surface of the belt 20 more closely.

[0045] Furthermore, the outer wall of the aforementioned sealing plate 1 is provided with a screw 4 for fitting into the waist hole 23, and a nut is used to fit onto the screw 4 to fix the upper edge of the mounting plate 2. The screw 4 can be integrally formed with the sealing plate 1, or it can be a bolt independent of the sealing plate 1.

[0046] Both the sealing plate 1 and the mounting plate 2 mentioned above are made of metal materials to ensure sufficient structural strength and stability.

[0047] The sealing plate 1 has folded edges 11 on its edges, and adjacent folded edges 11 are locked together using bolts and nuts. The longitudinal guide cavity 101 is fixed to the frame 40 of the belt conveyor 20, and the folded edges 11 are locked to the frame 40, and the mounting plate 2 is locked to the folded edges 11 using bolts and nuts. Thus, adjacent guide units 10 are also fixed together using bolts, which facilitates installation and maintenance.

[0048] The aforementioned skirt plate 3 is made of special polymer materials, such as polycarbonate and polyimide, which can ensure the wear resistance of the skirt plate 3 and improve its service life.

[0049] This utility model also includes a guide tube 50 connected to the upper surface of one of its longitudinal guide chambers 101.

[0050] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
