Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor roller sealing devices, and in particular to a belt conveyor roller sealing device. Background Technology

[0002] In industrial settings such as mines, ports, and power plants where belt conveyors are used for material transport, the belt conveyor rollers are the core transmission components, and their normal operation is crucial to the entire conveying system. However, traditional belt conveyor roller covers have significant defects in sealing performance, which seriously affect production safety and equipment lifespan.

[0003] The existing patent, with publication number CN208413054U, entitled "A Sealing Assembly for a Belt Conveyor Drum," proposes that the sealing assembly includes a bearing housing, a cylinder, and a drum shaft. The cylinder contacts the belt of the belt conveyor and is fixedly connected to the drum shaft. The bearing housing is installed on both sides of the drum shaft and is mounted on a ground foundation and secured with anchor bolts. This technical solution integrates the bearing and bearing housing, allowing for direct installation without heating. It employs a reliable sealing structure to prevent moisture and dust from entering, effectively extending bearing life and ensuring the safe operation of the drum.

[0004] However, the aforementioned conveyor belt rollers still lack effective sealing designs in areas such as the observation window and coal cleaning port. The observation window is simply fixed to the protective cover window with bolts, leaving large gaps. During the operation of the conveyor belt, the airflow generated by the roller rotation carries a large amount of dust, which escapes through these gaps. Taking underground conveyor belts in coal mines as an example, since the dust concentration in the underground environment is already high, dust leakage from traditional protective covers causes the dust concentration in the working area to soar further, far exceeding safety standards. Long-term exposure to high dust environments not only seriously endangers the health of operators and easily leads to occupational diseases such as pneumoconiosis, but also causes frequent malfunctions of electrical equipment due to dust accumulation, increasing equipment maintenance costs and downtime. Therefore, the above problems need to be solved. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-4 This utility model discloses a conveyor belt drum sealing device, comprising a cover 1, on which a first hinge 7 is fixedly connected. The first hinge 7 ensures that the observation window 2 is securely installed and rotates flexibly, allowing operators to observe the operation of the conveyor belt drum as needed. The cover 1 has a window, and the other end of the first hinge 7 is bolted to the observation window 2, enabling visual monitoring of the conveyor belt drum's operation and facilitating timely detection of drum abnormalities. The observation window 2 is hinged within the window via the first hinge 7. The bottom of the cover 1 has an opening, and a second hinge 11 is fixedly connected to the inner wall of the cover 1. The second hinge 11 ensures that the coal cleaning plate 4 is securely installed and rotates flexibly, facilitating coal cleaning operations. Simultaneously, the coal cleaning plate 4 can be closed in the non-working state to maintain the sealing state of the cover 1. The other end of the second hinge 11 is bolted to the coal cleaning plate 4, facilitating timely removal of accumulated coal near the drum and preventing coal accumulation from affecting the normal operation of the drum. The coal cleaning plate 4 is hinged within the opening.

[0021] In this utility model, a window handle 3 is fixedly connected to one side of the observation window 2, a second sealing strip 8 is affixed to the periphery of the observation window 2, and a protrusion 10 is fixedly connected to the top of the observation window 2. The second sealing strip 8 helps to ensure that the observation window 2 provides the observation function while maintaining the overall airtightness of the protective cover 1, reducing dust pollution to the working environment. A latch 9 is fixedly connected to the top of the window, and the inner wall of the latch 9 engages with the protrusion 10. The latch 9 helps to ensure that the position of the observation window 2 is fixed after it is closed, enhancing the stability of the observation window 2 and ensuring that the sealing effect of the protective cover 1 is not affected. A first sealing strip 6 is affixed to the periphery of the coal cleaning plate 4, and a plate handle 5 is welded to the bottom of the coal cleaning plate 4. Two fixing plates 12 are fixed to the bottom of the cover 1 and the coal cleaning plate 4 respectively. The first sealing strip 6 can effectively prevent dust from overflowing, keep the working environment clean, and protect the internal structure of the cover 1 from moisture corrosion, thus extending the service life of the sealing device. Each of the two fixing plates 12 has a hanging hole, and a locking ring 13 for fixing the coal cleaning plate 4 is inserted into the two hanging holes. The locking ring 13 can effectively fix the coal cleaning plate 4, prevent the coal cleaning plate 4 from being opened or shaken accidentally, and ensure the normal operation of the sealing device and the cleanliness of the working environment. The first sealing strip 6 and the second sealing strip 8 are made of rubber and both of them have a waterproof coating.

[0022] Working principle: In the use of this utility model, the protective cover 1, as the main body of the device, completely encloses the conveyor belt roller, forming a basic sealed space. The observation window 2 is hinged to the window of the protective cover 1 via the first hinge 7. When closed, the second sealing strip 8 on the periphery tightly fits the edge of the window, filling the gaps and preventing dust from leaking out through the gaps in the observation window 2. The protrusion 10 at the top of the observation window 2 engages with the latch 9 at the top of the window, further fixing the position of the observation window 2 and enhancing the sealing performance. The coal cleaning plate 4 is hinged to the protective cover 1 via the second hinge 11. Inside the plate opening, in the non-working state, the coal cleaning plate 4 is closed, and its first sealing strip 6 is fitted with the protective cover 1 to prevent dust from leaking from the plate opening. At the same time, the protective cover 1 and the fixing plate 12 at the bottom of the coal cleaning plate 4 are connected by the locking ring 13 to firmly fix the coal cleaning plate 4, preventing the coal cleaning plate 4 from loosening due to vibration or other factors, ensuring the sealing performance of the entire sealing device, effectively reducing dust leakage, and maintaining a clean working environment. Then, when it is necessary to observe the running status of the belt conveyor drum, the operator holds the window handle 3 on one side of the observation window 2 to... Using hinge 7 as the axis, pull the observation window 2 outward to open it by rotating it around the hinge. At this time, the operator can clearly observe the rotation of the drum, the fit between the belt and the drum, and whether there are any problems such as belt misalignment through the observation window 2. After observation, push the observation window 2 to close it. The protrusion 10 automatically engages with the slot 9 to fix the observation window 2. The second seal 8 resumes its sealing function to prevent dust leakage, ensuring that the observation window 2 has both convenient observation function and does not affect the overall sealing performance of the device. Finally, regarding the principle of coal cleaning, the operator holds the handle 5 at the bottom of the coal cleaning plate 4 and lifts the coal cleaning plate 4 upward with the second hinge 11 as the axis, so that the coal cleaning plate 4 rotates around the hinge to open. After the coal cleaning plate 4 is opened, the operator can use tools to clean the coal accumulation near the drum. After cleaning, lower the coal cleaning plate 4 to reset it and close it. The first seal 6 reseals the connection between the coal cleaning plate 4 and the protective cover 1. Then, the locking ring 13 passes through the hanging hole on the fixing plate 12 to fix the coal cleaning plate 4. At this point, the use of the belt conveyor drum sealing device is completed.
