Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to an expanded capacity flip-door double-sealed discharging chute. Background Art

[0002] At present, due to the advantages of large conveying capacity, simple structure, convenient maintenance, low cost, strong versatility, etc., belt conveyors have been widely used in the fields of metallurgy, coal, transportation, hydropower, chemical industry, etc.; when transporting materials, the impact air flow generated when the materials fall downward from the head of the upper belt conveyor will carry out the dust in the materials. Under the action of the impact air flow, the dust obtains the escape power and diffuses and drifts into the surrounding air. Moreover, a strong air flow will be generated along the running direction of the belt, and the dust can diffuse over a long distance with the air flow. Therefore, adding a guiding chute at the receiving position of the belt conveyor is an important step in the conveying system. The guiding chute is mainly used for belt conveyors. Installing the guiding chute at the receiving place of the belt conveyor can make the materials falling from the funnel be concentrated in the middle of the conveyor belt before reaching the belt speed, and restrain the materials from scattering outwards.

[0003] The common guiding chute structure includes a circular top cover plate, a visible observation door, a Z-shaped side plate, a roller support and rollers, legs, etc. installed on the roller support. The upper end of the Z-shaped side plate is bolted to the circular top cover plate, and a visible observation door is installed between the outer side of the Z-shaped side plate and the roller support. Since the wear of components such as the conveyor belt, the slide plate, and the anti-spill skirt is inevitable, these wear not only affects the conveying efficiency but also may cause material spillage and dust pollution. Through the visible observation door, the operator can directly observe the conditions of the anti-spill skirt and the Z-shaped plate, and timely discover and handle potential problems.

[0004] Although the above structure has achieved certain results in reducing material spillage and dust pollution, the replacement process of its sealing structure is rather cumbersome. Since multiple bolts are used to connect the visible observation door and the Z-shaped side plate, the disassembly and assembly are not only time-consuming and laborious but also increase the parking time, which has a certain impact on the production efficiency.

[0005] Based on the above problems, the utility model proposes an expanded capacity flip-door double-sealed guiding chute. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides an expanded capacity flip-door double-sealed guiding chute to achieve the technical effects of convenient and fast disassembly and assembly and saving maintenance and replacement time.

[0007] To achieve this technical purpose, the utility model adopts the following scheme:

A visual observation door is arranged outside the outer side plate corresponding to the position of the opening. The top cover plate is connected to the top of the outer side plate. A sliding plate is arranged at the lower part of the outer side plate. A Z-shaped side plate is arranged inside the outer side plate. A wear-resistant lining plate is arranged on one side of the lower part of the Z-shaped side plate, and an anti-overflow skirt plate is connected on the other side. The Z-shaped side plate is placed between the anti-overflow skirt plate and the wear-resistant lining plate. The conveyor belt is placed between the anti-overflow skirt plate and the sliding plate. A dust suppression curtain is arranged on the top cover plate, and the lower end of the dust suppression curtain is in contact with and seals the conveyor belt.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] By introducing the outer side plate, the present utility model realizes the independent installation of the Z-shaped side plate and the visual observation door. When disassembling, repairing or replacing, it is not necessary to remove the side plate of the entire diversion chute, and only the Z-shaped side plate needs to be directly disassembled. In addition, the visual observation door is hinged to the outer side plate by flipping, making the opening and closing operation simple and fast, and significantly reducing the time required for maintenance.

[0011] Further, the preferred solution adopted by the present utility model is:

[0012] The lower part of the outer side plate is hinged to the bottom of the visual observation door, and the upper part of the visual observation door is connected to the outer side plate through a metal lap buckle.

[0013] A protective net is also arranged between adjacent legs. The protective net is placed below the outer side plate and corresponds to the position of the idler.

[0014] It also includes an idler bracket. Both ends of the idler bracket are placed on the frame of the belt conveyor through pads.

[0015] On the outer side of the outer side plate, an outwardly protruding insertion plate is arranged around the opening. On the inner side of the visual observation door, a clamping plate adapted to the insertion plate is arranged around it. The visual observation door is connected to the outer side plate through the cooperation of the clamping plate and the insertion plate.

[0016] A sealing strip is arranged between the clamping plate and the insertion plate.

[0017] Both ends of the idler bracket are respectively provided with lapping plates. A positioning bolt is movably connected between the lapping plate and the frame of the belt conveyor. The lapping plate and the positioning bolt can slide up and down on the frame of the belt conveyor. A through groove is formed in the side of the pad close to the idler bracket corresponding to the position of the positioning bolt.
