Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a closed structure for a belt conveyor and a belt conveyor system. Background Technology

[0002] Modern large blast furnaces require tens of thousands of tons of raw materials and fuels continuously every day. All materials must be transported to the blast furnace via a transfer system and unloading vehicles. Belt conveyors, also known as conveyor belts, are crucial equipment in the raw material transportation system of steel enterprises. Due to the characteristics of the materials, dust is inevitably generated during the transfer of raw materials and fuels. Traditional technologies only enclose the conveyor belt corridor; belt conveyors do not have an enclosed structure, allowing dust to easily spill out during material transportation, polluting the work environment and endangering worker health.

[0003] At the enclosed sections of the belt conveyor corridor, the upper enclosure of the belt conveyor uses a belt conveyor cover, while the lower enclosure uses movable cover plates. Continuous channel steel is installed beside the intermediate frames on both sides, and each cover plate is fixed to the channel steel by two bolts. The cover plates are composed of square steel, angle steel, and steel plates. Workers can only perform maintenance operations by loosening the bolts and removing the cover plates. This type of belt conveyor enclosure structure lacks observation holes, making it difficult to detect problems such as belt conveyor deviation or material leakage. Furthermore, the use of steel plate seals makes them prone to rusting and aging in humid areas. Therefore, developing a mature belt conveyor enclosure structure is urgently needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a closed structure for a belt conveyor and a belt conveyor system, which can solve the problem that existing belt conveyors are prone to deviation.

[0005] The specific technical solution of this utility model embodiment is as follows:

[0006] A closed structure for a belt conveyor, the closed structure comprising:

[0007] A housing for covering a belt conveyor, the housing having a first side wall and a second side wall oppositely disposed, and a top wall having a material inlet on the top wall;

[0008] Two material inlet adjusting devices are respectively installed on the side of the material inlet near the first sidewall and the side of the material inlet near the second sidewall. Each material inlet adjusting device includes: a base, the connecting part of the base being connected to the top wall at the material inlet; a liner hinged to the support part of the base, the liner being located on the side of the support part facing the material inlet; and an inclination adjusting mechanism installed on the support part of the base, the inclination adjusting mechanism being throttledly connected to the liner so that the liner rotates about the hinge connection, thereby changing the inclination angle of the liner.

[0009] Preferably, the tilt adjustment mechanism includes: a rod with external threads and an operating part connected to the rod;

[0010] The base has a threaded hole on its support part. The rod passes through the threaded hole, and the external thread of the rod engages with the threaded hole. The end of the rod abuts against the liner. By rotating the operating part, the rod is displaced relative to the threaded hole toward the liner, thereby causing the end of the rod to abut against the liner and causing the liner to rotate around the hinge connection, thus changing the tilt angle of the liner.

[0011] Preferably, the hinged connection between the liner and the support portion of the base is located at the upper end of the liner;

[0012] By rotating the operating part, the rod body is displaced relative to the threaded hole in a direction away from the liner plate, thereby causing the end of the rod body to move away from the liner plate. Under the action of gravity, the liner plate rotates around the hinge connection, thereby changing the tilt angle of the liner plate.

[0013] Preferably, a raised liner mounting seat is connected to the upward-facing side of the support portion of the base, and the liner is hinged to the liner mounting seat.

[0014] Preferably, the lower end of the support portion of the base is connected to a plate made of flexible material, the plate being extended to the vicinity of the conveyor belt of the belt conveyor.

[0015] Preferably, the lower end of the support portion of the base is connected to a clamping member, a pressure plate is provided between the clamping member and the support portion, and the plate body is located between the pressure plate and the support portion; a clamping member is provided on the clamping member, and the clamping member is threadedly connected to the clamping member; by rotating the clamping member, one end of the clamping member can abut against the pressure plate, so that the pressure plate and the support portion clamp the plate body.

[0016] Preferably, the pressure plate has a V-shaped structure, with the pointed corners of the V-shaped structure abutting against the clamping member.

[0017] Preferably, the housing is made of galvanized steel sheet.

[0018] Preferably, the housing is equipped with an inspection door, the inspection door has a window, and an acrylic plate is installed at the window.

[0019] A belt conveyor system, the belt conveyor system comprising:

[0020] Belt conveyor;

[0021] As described above, in a closed structure for a belt conveyor, the casing covers the belt conveyor.

[0022] Preferably, the belt conveyor includes: an intermediate conveying idler, and two inclined conveying idlers located on both sides of the intermediate conveying idler and inclined towards the intermediate conveying idler, and a conveying belt is provided on the intermediate conveying idler and the inclined conveying idler;

[0023] The lower end of the support portion of the base is connected to a plate made of flexible material, which extends to the vicinity of the conveyor belt on the inclined conveyor roller.

[0024] The technical solution of this utility model has the following significant beneficial effects:

[0025] The primary cause of belt conveyor belt deviation is the material not being centered on the conveyor belt. Therefore, this enclosed belt conveyor structure incorporates a material inlet adjustment device on the casing. Through an inclination adjustment mechanism, the liner can rotate around the hinged connection, thereby changing the inclination angle of the liner. When material enters the casing through the material inlet and falls onto the conveyor belt, it is guided by the inclined liner, causing a suitable horizontal deviation and converging towards the center of the conveyor belt. This reduces the likelihood of belt deviation. Attached Figure Description

Detailed Implementation

[0033] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.

[0034] To address the problem of belt conveyor misalignment in existing belt conveyors, this application proposes a closed structure for the belt conveyor. Figure 1 This is a schematic diagram of the enclosed structure of the belt conveyor in an embodiment of this utility model. Figure 2 for Figure 1 Enlarged view of the two material inlet regulating devices, as shown below. Figure 1 and Figure 2 As shown, the belt conveyor enclosure structure 200 may include: a housing 1 for covering the belt conveyor 100; and a material inlet regulating device 2.

[0035] like Figure 1 and Figure 2As shown, the housing 1 may have a first sidewall 111, a second sidewall 112, and a top wall disposed opposite to each other, with a material inlet 11 on the top wall. The first sidewall 111, the second sidewall 112, and the top wall extend along the material conveying direction of the belt conveyor 100. External materials can be input into the housing 1 through the material inlet 11, thereby reaching the conveyor belt 103 of the belt conveyor 100. The material inlet 11 is located directly above the conveyor belt 103 of the belt conveyor 100, thereby ensuring that materials entering from the material inlet 11 fall onto the conveyor belt 103 of the belt conveyor 100 under the action of gravity.

[0036] like Figure 1 and Figure 2 As shown, there can be two material inlet adjusting devices 2, which are respectively installed on the side of the material inlet 11 near the first side wall 111 and the side near the second side wall 112. Each material inlet adjusting device 2 may include: a base 21, the connecting part 211 of the base 21 being connected to the top wall at the material inlet 11; a liner 22 hinged to the support part 212 of the base 21, the liner 22 being located on the side of the support part 212 facing the material inlet 11; and an inclination adjustment mechanism 23 installed on the support part 212 of the base 21, the inclination adjustment mechanism 23 being tractively connected to the liner 22 so that the liner 22 rotates around the hinge connection, thereby changing the inclination angle of the liner 22.

[0037] The primary cause of belt conveyor belt 103 deviation is the material not being centered on the belt conveyor belt 103. Therefore, the enclosed structure 200 of this belt conveyor has a material inlet adjustment device 2 installed on the housing 1. The tilt adjustment mechanism 23 allows the liner 22 to rotate around the hinged connection, thereby changing the tilt angle of the liner 22. When material enters the housing 1 through the material inlet 11 and falls onto the belt conveyor belt 103, the material is guided by the tilted liner 22 and deflects appropriately on the horizontal plane, causing the material to concentrate towards the center of the belt conveyor belt 103. This reduces the likelihood of belt conveyor belt 103 deviation.

[0038] like Figure 2As shown, the tilt adjustment mechanism 23 may include: a rod 231 with external threads and an operating part 232 connected to the rod 231. The operating part 232 may be an adjusting handwheel, which rotates the rod 231. A threaded hole is provided on the support part 212 of the base 21, through which the rod 231 passes, and the external thread of the rod 231 engages with the threaded hole. The end of the rod 231 abuts against the liner plate 22. By rotating the operating part 232, the rod 231 is displaced relative to the threaded hole towards the liner plate 22, thereby causing the end of the rod 231 to abut against the liner plate 22, causing the liner plate 22 to rotate around the hinge connection, thereby changing the tilt angle of the liner plate 22. In the above process, the angle between the liner plate 22 and the vertical direction increases, which allows the material to be further concentrated towards the center of the conveyor belt 103 of the belt conveyor 100.

[0039] like Figure 2 As shown, the hinged connection between the liner 22 and the support portion 212 of the base 21 is located at the upper end of the liner 22. By rotating the operating part 232, the rod 231 is displaced relative to the threaded hole in a direction away from the liner 22, thereby causing the end of the rod 231 to move away from the liner 22. Under the action of gravity, the liner 22 rotates around the hinged connection, thereby changing the tilt angle of the liner 22. During the above process, the angle between the liner 22 and the vertical direction decreases, which allows the material to be dispersed away from the center of the conveyor belt 103 of the belt conveyor 100.

[0040] like Figure 2 As shown, a raised liner mounting seat 24 is connected to the upward-facing side of the support portion 212 of the base 21, and the liner 22 is hinged to the liner mounting seat 24. This method increases the degree of adjustment of the inclination of the liner 22 to some extent.

[0041] like Figure 2 As shown, the lower end of the support portion 212 of the base 21 is connected to a plate 25 made of flexible material. The plate 25 is used to extend to the vicinity of the conveyor belt 103 of the belt conveyor 100, thereby preventing the material on the conveyor belt 103 of the belt conveyor 100 from spreading to both sides to the outside of the plate 25.

[0042] To secure and replace the plate 25, or to adjust the position of its lower end, a clamping member 26 is connected to the lower end of the support portion 212 of the base 21. A pressure plate 27 is positioned between the clamping member 26 and the support portion 212, with the plate 25 located between the pressure plate 27 and the support portion 212. A clamping member 28 is threaded onto the clamping member 26. Rotation of the clamping member 28 causes one end to press against the pressure plate 27, clamping the plate 25 between the pressure plate 27 and the support portion 212. Loosening the clamping member 28 allows for replacement of the plate 25 or adjustment of its lower end.

[0043] Furthermore, such as Figure 2 As shown, the pressure plate 27 has a V-shaped structure, with the pointed corner of the V-shaped structure abutting against the clamping member 26. This makes it easier for the other end of the pointed corner of the V-shaped structure to press against the plate body 25.

[0044] To increase the wear resistance and impact resistance of the liner 22, the liner 22 can be made of wear-resistant metal material.

[0045] To improve the sealing between the plate 25 and the conveyor belt 103 of the belt conveyor 100, the plate 25 can be made of rubber material, so that even if the plate 25 comes into contact with the conveyor belt 103, there will be no problem of jamming.

[0046] Alternatively, the housing 1 can be made of galvanized steel sheet, which would provide better corrosion resistance and prevent rusting and aging.

[0047] As a feasible option, Figure 3 This is a schematic diagram of the maintenance door on the housing of the enclosed structure of the belt conveyor in this embodiment of the present invention. Figure 4 This is a schematic diagram of the interior of the inspection door window on the housing of the enclosed structure of the belt conveyor in an embodiment of this utility model. Figure 3 and Figure 4 As shown, a maintenance door 12 is installed on the housing 1. The maintenance door 12 can be a swing-open structure. This facilitates operation when the belt conveyor 100 needs maintenance or when the conveyor belt 103 deviates from its designated path. The maintenance door 12 has a window 121, and an acrylic plate 122 is installed at the window 121. The acrylic plate 122 is transparent, allowing workers to easily observe the status of the conveyor belt 103 on the belt conveyor 100.

[0048] This application also proposes a belt conveyor system 100, such as Figure 1 As shown, the belt conveyor 100 system may include: a belt conveyor 100; and a belt conveyor enclosure structure 200 as described above, in which the housing 1 covers the belt conveyor 100.

[0049] Furthermore, such as Figure 1 As shown, the belt conveyor 100 may include: an intermediate conveying roller 101, and two inclined conveying rollers 102 located on both sides of the intermediate conveying roller 101 and inclined towards the intermediate conveying roller 101. A conveying belt 103 is provided on the intermediate conveying roller 101 and the inclined conveying rollers 102. The lower end of the support portion 212 of the base 21 is connected to a plate 25 made of flexible material, and the plate 25 extends to the vicinity of the conveying belt 103 on the inclined conveying rollers 102.
