Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for belt conveyors, and in particular to a dustproof and sealing protection device for belt conveyors. Background Technology

[0002] Belt conveyors, with their efficient and continuous material transport capabilities, are widely used in industries such as mining, port loading and unloading, thermal power generation, and building materials. During actual operation, the vibration and spillage of materials on the conveyor belt, as well as the friction between the conveyor belt and components such as rollers and idlers, generate a large amount of dust. Taking underground belt conveyors in coal mines as an example, statistics show that without effective dust control measures, the dust concentration in the working area can reach 50-100 mg / m³. 3 It far exceeds the national occupational exposure limit (8 mg / m³). 3 Prolonged exposure to such an environment greatly increases the risk of serious occupational diseases such as pneumoconiosis for operators. Furthermore, dust accelerates wear on conveyor belts and rollers, leading to malfunctions such as belt misalignment and impaired roller rotation. This reduces equipment maintenance cycles from the original 6 months to 3-4 months, significantly increasing maintenance costs and downtime. In locations involving flammable dust, such as flour mills and feed production workshops, dust explosions pose a serious threat to production safety.

[0003] Existing technologies, such as the utility model patent with publication number CN 217375993 U, disclose a dustproof device for a belt conveyor, belonging to the technical field of conveying equipment in the metallurgical industry. The technical solution is as follows: a dustproof cover is placed above the belt, and the dustproof cover is fixed to the conveyor frame by supports; a cover plate and side plates on both sides of the cover plate are connected together by cover plate bolts; the upper end of a rubber plate is fixed to the side plates on both sides of the cover plate, and the lower end of the rubber plate is tightly fitted to the belt; a hopper is fixed to the cover plate, and the cover plate has a discharge port matching the hopper. The beneficial effects of this utility model are: when the belt conveyor is being fed, the large amount of dust generated during the process of material falling onto the belt and being conveyed by the belt does not escape, reducing pollution to the surrounding environment and avoiding harm to the human body.

[0004] When using the above technical solution,

[0005] (1) Lacking dust collection function, relying solely on physical barriers cannot effectively handle the generated dust, making it difficult to reduce the dust concentration inside the dust cover and fundamentally solve the dust pollution problem. Lacking a stable connection structure, the dust cover is prone to displacement and loosening under the vibration generated by the belt conveyor.

[0006] (2) Some products are made of simple canvas or plastic sheet dust cover, which has poor sealing performance and cannot prevent fine dust from escaping; some sealing covers are made of metal material, but they are fixed connection, which is extremely inconvenient to install and disassemble. Each inspection and maintenance requires time to disassemble and reassemble, which seriously affects production efficiency.

[0007] To address the aforementioned problems, this utility model provides a dustproof and sealing protection device for belt conveyors. Utility Model Content

[0008] The purpose of this utility model is to solve the problems of lack of dust collection function, poor sealing effect, inconvenient installation and maintenance, and poor connection stability in the existing technology, and to propose a dustproof sealing protection device for belt conveyors.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof and sealing protection device for a belt conveyor, comprising a dust cover, a dust collection mechanism, a sealing connection mechanism, and a connection stabilization mechanism. The dust collection mechanism is fixedly connected to the top of the dust cover, the sealing connection mechanism is fixedly connected to the outer surface of the dust cover, and the connection stabilization mechanism is fixedly connected to the bottom of the dust cover. The dust collection mechanism includes an insertion hole opened at the top of the dust cover, a dust collection pipe is inserted into the insertion hole, and dust collection ports are fixedly connected at equal intervals on the outer surface of the dust collection pipe. The dust collection pipe and the dust collection ports are fixedly connected to the inside of the dust cover, and a vacuum cleaner is fixedly connected to both ends of the dust collection pipe. A dust collection box is fixedly connected to the outer surface of the vacuum cleaner.

[0010] Furthermore, a protective cover is threaded to the top of the dust collection box, and limiting members are threaded to both sides of the protective cover. The protective cover is threaded to the top of the protective cover through the limiting members. A connecting ring is sleeved on the outer surface of the dust suction pipe. The top of the connecting ring is fixedly connected to the inner top wall of the dust cover. A connecting bend plate is fixedly connected to the bottom of the dust collection box, and fasteners are threaded to both sides of the connecting bend plate. The dust collection box is threaded to the top of the dust cover through the fasteners.

[0011] Furthermore, the sealing connection mechanism includes an upper protrusion fixedly connected to one side of the dust cover, and a lower protrusion fixedly connected to the other side of the dust cover. Rubber sealing gaskets are engaged inside the upper and lower protrusions.

[0012] Furthermore, the upper and lower protrusions are threadedly connected to limit bolts on both sides, and the outer surface of the limit bolts is threadedly connected to limit nuts. The two dust covers are threadedly connected by the limit bolts and limit nuts, and the rubber sealing gasket is snapped into the gap between the upper and lower protrusions.

[0013] Furthermore, the sealing connection mechanism includes a sealing ring that snaps into the gap between the insertion hole and the dust extraction pipe, and the sealing ring is symmetrically arranged on both sides of the two dust covers.

[0014] Furthermore, the connection stabilization mechanism includes a fixed plate fixedly connected to the bottom of the dust cover, and shock-absorbing dampers are provided at four equal intervals on the fixed plate, with shock-absorbing telescopic springs sleeved on the outer surface of the shock-absorbing dampers.

[0015] Furthermore, a conveyor connecting plate is fixedly connected to the bottom of the shock absorber and the shock absorber extension spring, and conveyor connecting parts are threaded to both sides of the conveyor connecting plate. The conveyor connecting parts and the shock absorber extension spring are symmetrically arranged on both sides of the dust cover.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the dust collection pipe, dust collection port, and shock-absorbing telescopic spring are designed to actively and efficiently remove dust generated inside the dust cover. The dust collection port, in conjunction with the negative pressure generated by the vacuum cleaner, significantly improves dust capture efficiency. Dust is drawn into the pipe through the dust collection port and finally enters the dust collection box for collection, effectively reducing the dust concentration in the working area to below the national standard, significantly improving the working environment, and effectively protecting the health of operators. At the same time, the shock-absorbing damper and shock-absorbing telescopic spring in the connecting stabilizing mechanism are symmetrically distributed at the bottom of the dust cover, which can effectively absorb the vibration of the belt conveyor in all directions during operation, reduce the mutual influence between the device and the conveyor, significantly improve the stability and reliability of the device operation, extend the service life of the device, reduce the equipment failure rate, and reduce maintenance costs.

[0018] 2. In this utility model, the upper protrusion, lower protrusion, and rubber sealing gasket ensure a tight seal at both the connection points between dust covers and the connection points between the dust extraction pipe and the dust cover, effectively preventing dust leakage and significantly reducing dust leakage. This creates a clean and safe working environment for industrial production. The connection method of the limit bolts and limit nuts makes the installation and disassembly process simple and quick, greatly improving the efficiency of equipment maintenance, reducing downtime, and ensuring production continuity.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a dustproof and sealing protection device for a belt conveyor, including a dust cover 1, a dust suction mechanism 2, a sealing connection mechanism 3, and a connection stabilization mechanism 4. The dust suction mechanism 2 is fixedly connected to the top of the dust cover 1, the sealing connection mechanism 3 is fixedly connected to the outer surface of the dust cover 1, and the connection stabilization mechanism 4 is fixedly connected to the bottom of the dust cover 1.

[0028] The following section will explain the specific configuration and function of its dust collection mechanism 2, sealing connection mechanism 3, and connection stabilization mechanism 4.

[0029] In this embodiment: the dust collection mechanism 2 includes an insertion hole 21 opened on the top of the dust cover 1. A dust collection pipe 22 is inserted into the insertion hole 21. Dust collection ports 23 are fixedly connected at equal intervals on the outer surface of the dust collection pipe 22. The dust collection pipe 22 and the dust collection ports 23 are fixedly connected to the inside of the dust cover 1. A vacuum cleaner 24 is fixedly connected to both ends of the dust collection pipe 22. A dust collection box 25 is fixedly connected to the outer surface of the vacuum cleaner 24.

[0030] The effect achieved by the above components is as follows: after the belt conveyor generates dust, the vacuum cleaner 24 is started. The suction force generated by the vacuum cleaner creates a negative pressure environment in the vacuum pipe 22. The dust enters the vacuum pipe 22 through the vacuum port 23 and is eventually collected in the dust collection box 25 under the action of negative pressure, thereby achieving active removal of dust in the dust cover 1 and effectively reducing the dust concentration.

[0031] Specifically, a protective cover 26 is threadedly connected to the top of the dust collection box 25, and limiting members 27 are threadedly connected to both sides of the protective cover 26. The protective cover 26 is threadedly connected to the top of the protective cover 26 through the limiting members 27. A connecting ring 28 is sleeved on the outer surface of the dust suction pipe 22. The top of the connecting ring 28 is fixedly connected to the inner top wall of the dust cover 1. A connecting elbow 29 is fixedly connected to the bottom of the dust collection box 25. Fasteners 210 are threadedly connected to both sides of the connecting elbow 29. The dust collection box 25 is threadedly connected to the top of the dust cover 1 through the fasteners 210.

[0032] The above components achieve the following effects: the protective cover 26 cooperates with the limiting member 27 to facilitate opening the dust collection box 25 to clean the accumulated dust. After cleaning, tightening the limiting member 27 can ensure that the protective cover 26 is stable and prevent dust leakage. The connecting ring 28 supports and fixes the suction pipe 22 to prevent it from shaking or shifting during the suction process and ensure the stable operation of the suction system.

[0033] Specifically, the sealing connection mechanism 3 includes an upper protrusion 31 fixedly connected to one side of the dust cover 1, and a lower protrusion 32 fixedly connected to the other side of the dust cover 1. Rubber sealing gaskets 33 are snapped into the interior of the upper protrusion 31 and the lower protrusion 32.

[0034] The effect achieved by the above components is as follows: when splicing dust covers 1, the upper protrusion 31 of the previous dust cover 1 is aligned with the lower protrusion 32 of the next dust cover 1 and the rubber sealing gasket 33 is embedded. The rubber sealing gasket 33 has good elasticity and sealing performance. When the dust covers 1 are connected, it is squeezed and deformed, filling the gap between the upper protrusion 31 and the lower protrusion 32, forming a sealing barrier, effectively preventing dust from leaking from the connection of the dust cover 1, and enhancing the sealing performance of the dust protection device.

[0035] Specifically, the upper protrusion 31 and the lower protrusion 32 are threadedly connected to the two sides of the limiting bolt 34, and the outer surface of the limiting bolt 34 is threadedly connected to the limiting nut 35. The two dust covers 1 are threadedly connected by the limiting bolt 34 and the limiting nut 35, and the rubber sealing gasket 33 is snapped into the gap between the upper protrusion 31 and the lower protrusion 32.

[0036] The effect achieved by the above components is that by tightening the limiting bolts 34 and the limiting nuts 35, the upper protrusion 31 and the lower protrusion 32 can be tightly fitted together, further squeezing the rubber sealing gasket 33, ensuring that the dust cover 1 is firmly connected and tightly sealed. At the same time, this connection method is easy to disassemble and install, improving the convenience of equipment maintenance.

[0037] Specifically, the sealing connection mechanism 3 includes a sealing ring 36 that snaps into the gap between the insertion hole 21 and the dust suction pipe 22. The sealing ring 36 is symmetrically arranged on both sides of the two dust covers 1.

[0038] The effect achieved by the above components is as follows: the sealing ring 36 can fill the tiny gap between the insertion hole 21 and the suction pipe 22, prevent dust from escaping from the connection part, further improve the sealing performance of the connection between the suction pipe 22 and the dust cover 1, and together with the upper protrusion 31, the lower protrusion 32 and the rubber sealing gasket 33, it forms a multi-seal system to completely prevent dust leakage.

[0039] Specifically, the connection stabilization mechanism 4 includes a fixed plate 41 fixedly connected to the bottom of the dust cover 1. The fixed plate 41 is provided with shock absorbers 42 at four equal intervals. The outer surface of the shock absorbers 42 is fitted with shock absorber extension springs 43.

[0040] The effect achieved by the above components is as follows: when the belt conveyor vibrates during operation, the vibration is transmitted to the dust cover 1. First, the shock-absorbing telescopic spring 43 provides elastic buffering, using its elastic deformation to absorb part of the vibration energy and reduce the vibration impact. Then, the shock-absorbing damper 42 plays a role in further weakening the vibration amplitude. The two work together to effectively reduce the impact of vibration on the protective device and prevent the dust cover 1 from being displaced or loosened due to vibration.

[0041] Specifically, the bottom of the shock absorber 42 and the shock absorber extension spring 43 is fixedly connected to the conveyor connecting plate 44, and the two sides of the conveyor connecting plate 44 are threadedly connected to the conveyor connecting parts 45. The conveyor connecting parts 45 and the shock absorber extension spring 43 are symmetrically arranged on both sides of the dust cover 1.

[0042] The effects achieved by the above components are as follows: the conveyor connecting plate 44 and the conveyor connecting piece 45 realize a stable connection between the protective device and the belt conveyor frame. The symmetrical distribution design ensures that the protective device is subjected to uniform force. While the shock absorber 42 and the shock absorber extension spring 43 buffer the vibration, the conveyor connecting piece 45 ensures that the protective device will not shift due to vibration, so that the protective device is stably installed on the belt conveyor and ensures its reliable operation.

[0043] Working principle: Before the belt conveyor runs, the vacuum cleaner 24 in the dust collection mechanism 2 is started to create a negative pressure in the dust collection pipe 22. During the operation of the belt conveyor, the material vibration, spillage and component friction generate dust. Under the combined action of the negative pressure of the dust collection port 23, the dust is sucked into the dust collection pipe 22 and transported to the dust collection box 25 for storage.

[0044] In the sealing connection mechanism 3, adjacent dust covers 1 are tightly connected and sealed by upper protrusion 31, lower protrusion 32, rubber sealing gasket 33, limit bolt 34 and limit nut 35. At the same time, the sealing ring 36 ensures that there is no dust leakage at the connection between the dust suction pipe 22 and the dust cover 1, and prevents dust leakage in all directions.

[0045] The stabilizing mechanism 4 operates in real time. When the belt conveyor vibrates, the shock-absorbing telescopic spring 43 and the shock-absorbing damper 42 buffer and dissipate the vibration in sequence. Together with the conveyor connecting plate 44 and the conveyor connecting piece 45, they ensure that the protective device is firmly installed and does not shift due to vibration. This allows the entire dustproof sealing protection device to operate continuously, stably, and efficiently, achieving effective control of dust during the operation of the belt conveyor.
