Description

Technical Field

[0001] This utility model relates to the field of dust prevention technology for mobile belt conveyors, and in particular to a sealing device for mobile belt conveyors. Background Technology

[0002] During the operation of belt conveyors, a significant amount of dust is generated due to the transport of iron ore powder, limestone, coke dust, etc. This not only pollutes the environment but also poses a certain threat to the health of maintenance workers. The conventional solution is to cover the belt conveyor with a fixed cover to reduce dust pollution caused by wind and the above-mentioned factors. However, when maintaining the belt conveyor, the cover needs to be opened. Once the cover is opened, the dust that was originally accumulated inside the cover will be directly released into the outside environment, polluting the environment. Furthermore, the dust inside the cover takes a long time to dissipate before it can be entered to maintain the mobile belt conveyor, affecting maintenance efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a sealing device for a mobile conveyor belt, so as to solve the technical problem that existing mobile conveyor belts require waiting for the dust in the dust cover to dissipate during maintenance, which affects the maintenance efficiency.

[0004] To achieve the above objectives, this utility model provides a mobile conveyor enclosure device for isolating the working environment of the mobile conveyor from the external environment. The device includes a dust cover, the interior of which has a sealed space for housing the mobile conveyor. The exterior of the dust cover has at least one entrance connecting to the sealed interior space. The dust cover has a sealing component at the entrance for opening and closing the entrance. The exterior of the dust cover also has at least one feeding pipe for feeding materials onto the conveyor surface of the mobile conveyor. One end of the feeding pipe is connected to a dust collector pipe, and the other end of the dust collector pipe is connected to the air inlet of a dust collector.

[0027] like Figure 1 and Figure 2 As shown, a mobile conveyor enclosure device is used to isolate the working environment of the mobile conveyor 9 from the external environment. It includes a dust cover, the interior of which has a sealed space for placing the mobile conveyor 9. The exterior of the dust cover is provided with at least one entrance that connects to the interior sealed space. The dust cover is provided with a sealing component at the entrance for opening and closing the entrance. The exterior of the dust cover is provided with at least one feeding pipe 10 for feeding materials onto the conveying surface of the mobile conveyor 9. The feeding pipe 10 is connected to one end of a dust removal pipe 12, and the other end of the dust removal pipe 12 is connected to the air inlet of a dust collector.

[0028] The above technical solution can absorb dust in the dust cover in real time. When in use, open the feed pipe 10 and put the material into the dust cover. The material falls onto the conveying surface of the mobile belt conveyor 9 under the action of gravity. During the movement of the material, a large amount of dust will be generated. The mobile belt conveyor 9 transports the material to the designated area. At this time, the dust collector is started to suck the dust away from the dust cover through the dust collection pipe 12, thereby maintaining the air quality inside the dust cover. During maintenance, operate the sealing component to open the entrance on the surface of the dust cover. Since the dust inside the dust cover has been treated, it will not pollute the external environment. Moreover, the environment inside the dust cover is relatively clean, and the staff can directly enter the dust cover to maintain the mobile belt conveyor 9.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the dust cover includes: a fixed door frame 1, which is installed on both sides and in the middle of the mobile conveyor belt 9; multiple fixed doors 2 around the fixed door frame 1; and multiple top sealing plates 6 on the top of the fixed door frame 1. The fixed door frame 1, the fixed doors 2, and the top sealing plates 6 together form a sealed space. Specifically, the fixed door frame 1 has first bolt holes pre-drilled around its interior, and the fixed door 2 has corresponding second bolt holes on its contact surface with the fixed door frame 1. Bolts pass through the first bolt holes and the second bolt holes, and one end of the bolt is connected to a nut that matches it. The fixed door frame 1 is made of channel steel welded together, and the fixed door 2 is made of angle steel. The surface of the fixed door 2 is covered with a layer of color steel sheet.

[0030] The above technical solution enables the dust cover to be detachable, which is beneficial for maintenance. The fixed door 2 is installed on the fixed door frame 1 in a detachable manner by bolts and nuts. Under normal circumstances, it is not disassembled. In case of major repairs, the bolt connection can be removed and the fixed door 2 can be removed for inspection. The top sealing plate 6 is installed on the top of the fixed door frame 1 to prevent dust from spreading from the top.

[0031] like Figure 1 and Figure 3 As shown, in this embodiment, the sealing assembly includes: a sliding door track 4 installed on the fixed door frame 1 near the entrance; a sliding door roller 5 with one end adapted to the sliding door track 4, and the other end of the sliding door roller 5 fixedly connected to the sliding door 3; specifically, a bolt 8 for passing through the sliding door roller 5 and the sliding door 3 is provided between the sliding door roller 5 and the sliding door 3, and one end of the bolt 8 is connected to a nut adapted to it;

[0032] The above technical solution can control the opening or closing of the dust cover entrance. During maintenance, the sliding door 3 is pushed to move relative to the fixed door frame 1. The sliding door roller 5 can cooperate with the sliding door track 4 to guide the linear movement of the sliding door 3, thereby making the sliding door 3 misaligned with the entrance, opening the entrance, and making it convenient for workers to enter the dust cover through the entrance. After maintenance is completed, the sliding door 3 is operated again to close the entrance.

[0033] like Figure 2 As shown, in this embodiment, the surface of the sliding door 3 is provided with a handle 7;

[0034] The above technical solution facilitates the pushing and pulling of sliding doors 3.

[0035] like Figure 2 As shown, in this embodiment, the dust cover has two inlets on its surface that correspond to the head and tail of the moving conveyor belt 9, respectively;

[0036] The above technical solution facilitates the maintenance of the mobile belt conveyor 9. The head and tail of the mobile belt conveyor 9 are frequently required to be maintained. Therefore, two entrances are opened at corresponding locations on the dust cover to facilitate access for maintenance of the mobile belt conveyor 9.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the feed pipe 10 is connected to a butterfly valve 11;

[0038] The above technical solution can control the material release or stop the material conveying by the feed pipe 10.

[0039] like Figure 2 As shown, in this embodiment, there are two feeding pipes 10, which are respectively located at the top of the dust cover corresponding to the head and tail of the mobile belt conveyor 9.

[0040] The above technical solution allows for easy adjustment of the conveying direction. Since there are discharge pipes 10 on both sides of the dust cover, one side can be selected for discharge.

[0041] Working principle: During use, open the feed pipe 10 and put the material into the dust cover. Under the action of gravity, the material falls onto the conveyor surface of the mobile belt conveyor 9. During the movement of the material, a large amount of dust will be generated. The mobile belt conveyor 9 transports the material to the designated area. At this time, the dust collector is started to suck the dust away from the dust cover through the dust collection pipe 12, thereby maintaining the air quality inside the dust cover. During maintenance, operate the sealing component to open the entrance on the surface of the dust cover. Since the dust inside the dust cover has been treated, it will not pollute the external environment. Moreover, the environment inside the dust cover is relatively clean, and you can directly enter the dust cover without waiting for the dust to dissipate. During maintenance, push the sliding door 3 by holding the handle 7 to move it relative to the fixed door frame 1. The sliding door roller 5 can cooperate with the sliding door track 4 to guide the linear movement of the sliding door 3, thereby making the sliding door 3 misaligned with the entrance and opening the entrance, so that workers can easily enter the dust cover through the entrance. After maintenance is completed, operate the sliding door 3 again to close the entrance. The maintenance efficiency is high.
