Description

Technical Field

[0001] This application relates to the field of material conveying and dust collection technology, specifically to a dust collection device for a mobile unloading vehicle of a belt conveyor. Background Technology

[0002] As an important unloading device, the belt conveyor unloading trolley plays a crucial role in industrial material handling systems. With the rapid development of industry, the demands for efficiency and precision in material handling are constantly increasing. The belt conveyor unloading trolley, with its ability to perform series operations on belt conveyors and flexibly unload materials according to different characteristics, meets the material handling needs of various industrial scenarios. It has been widely used in many industries such as mining, chemical, and power, greatly improving the flexibility and convenience of material handling.

[0003] In the past, various methods were typically employed in the industry to address the dust problem generated during unloading. One common method was using spray nozzles for dust suppression, which involved setting up spray devices around the unloading area to adsorb airborne dust particles by spraying water mist, thereby achieving dust reduction. Another method involved installing shielding structures at the unloading port, such as simple baffles, to attempt to prevent the spread of dust. Additionally, some companies opted to install ventilation ducts to guide dust-laden air to specific areas for centralized treatment, thereby reducing the dust content in the working environment. These methods, to a certain extent, can control dust.

[0004] However, existing technologies have significant drawbacks. For example, dust suppression using spray nozzles requires a large spray volume to achieve a certain dust reduction effect, but excessive spray volume can increase the moisture content of the material, severely affecting its storage or usability. While shielding structures can only partially block dust, they cannot effectively remove it, and ventilation ducts cannot completely capture all dust, thus failing to fundamentally solve the dust pollution problem. Utility Model Content

[0005] In order to overcome the problems of poor dust suppression effect and excessively high material moisture content caused by the existing spray dust suppression method, this application provides a dust collection device for a belt conveyor mobile unloading vehicle.

[0006] This application adopts the following technical solution: a dust collection device for a belt conveyor mobile unloading vehicle, including a frame, a belt of the conveyor inserted inside the frame, a discharge hopper provided at the lower part of the inner side of the frame, the end of the belt located above the discharge hopper, a dust collection unit mounted above the frame, the dust collection unit including a fan and a filter box, an air inlet at the bottom of the filter box, an air outlet on the side of the filter box, the fan communicating with the air outlet, and a filter assembly provided between the air outlet and the air inlet;

[0007] The filter assembly includes a frame and a filter cartridge. The frame is connected to the filter box, and the filter cartridge is sleeved on the outside of the frame.

[0025] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] like Figure 1-6 As shown, the dust collection device for the belt conveyor mobile unloading vehicle includes a frame 1, a dust collection unit, and an unloading hopper 3. The frame 1 supports the entire device. The dust collection unit is mounted above the frame 1. The unloading hopper 3 is located on the lower inner side of the frame 1. The conveyor belt 2 is inserted inside the frame 1, with its end positioned above the unloading hopper 3. This allows the dust generated when material falls from the end of the belt 2 into the unloading hopper 3 to be effectively collected by the dust collection unit above, preventing dust from spreading to the surrounding environment. Simultaneously, the frame 1 is equipped with a flexible dust curtain 11, which can be made of flexible materials such as rubber or plastic. The belt 2 passes through the dust curtain 11 and enters the inner side of the frame 1. The function of the dust curtain 11 is to reduce the possibility of dust leakage through gaps when the belt 2 enters the frame 1, providing initial dust prevention.

[0027] The dust collection unit includes a fan 4 and a filter box 5. The filter box 5 provides a relatively enclosed space for dust collection and filtration. The bottom of the filter box 5 has an air inlet 51, and the side of the filter box 5 has an air outlet 52. The fan 4 is connected to the air outlet 52. When the fan 4 starts, it creates a negative pressure inside the filter box 5, causing dust-laden air to enter the filter box 5 through the air inlet 51. A filter assembly 6 is located between the air outlet 52 and the air inlet 51 of the filter box 5. The filter assembly 6 is used to filter dust from the dust-laden air. Specifically, the filter assembly 6 includes a frame 61 and a filter cartridge 62. The frame 61 can be made of metal, possessing a certain strength and rigidity, providing support for the filter cartridge 62 and ensuring that the filter cartridge 62 maintains a stable shape during the filtration process. The frame 61 is connected to the filter box 5 and can be fixed inside the filter box 5 by welding, bolting, or other methods. The filter cartridge 62 is fitted onto the outside of the frame 61. The filter cartridge 62 is generally made of a fiber material with good filtration performance, such as polyester fiber, which can effectively intercept dust particles.

[0028] The filter box 5 is equipped with a partition 53, which divides the internal space of the filter box 5 into a dust collection chamber 54 and an exhaust chamber 55. The air inlet 51 is connected to the dust collection chamber 54, and the dust-laden air first enters the dust collection chamber 54. The air outlet 52 is connected to the exhaust chamber 55, and the filtered clean air is discharged from the exhaust chamber 55. The partition 53 is provided with a through hole 530 connecting the dust collection chamber 54 and the exhaust chamber 55. The air outlet of the filter cartridge 62 is installed on the partition 53 and is connected to the through hole 530. In this way, the dust-laden air is filtered by the filter cartridge 62 in the dust collection chamber 54, and the clean air enters the exhaust chamber 55 through the through hole 530 and is finally discharged from the air outlet 52.

[0029] One end of the frame 61 is equipped with a chuck 611, which increases the contact area between the frame 61 and the partition 53, allowing the frame 61 to be more stably installed on the partition 53. The chuck 611 fits snugly against the partition 53 and can be sealed with sealing strips or similar materials to prevent dust leakage from the connection between the chuck 611 and the partition 53. The other end of the frame 61 is equipped with a limiting plate 612, which is located inside the filter cartridge 62 and has a limiting rod 613. The filter box 5 has a mounting hole 56 on one side wall away from the partition 53. The filter cartridge 62 is fitted onto the outside of the frame 61 through the mounting hole 56 and slides into the dust collection chamber 54, facilitating the installation and replacement of the filter cartridge 62. The limiting rod 613 is used to position and fix the filter cartridge 62 and the sealing cover 57. The outer wall of the filter box 5 is provided with a sealing installation hole 56 and a sealing cover 57 for the air outlet port of the filter cartridge 62. The sealing cover 57 can ensure the airtightness of the filter box 5 and prevent dust from leaking from the installation hole 56. The limiting rod 613 passes through the sealing cover 57 and extends to the outside of the filter box 5. A knob 58 for locking the sealing cover 57 is screwed on the limiting rod 613. By tightening the knob 58, the sealing cover 57 can be firmly fixed to the filter box 5, ensuring the sealing performance of the filter box 5.

[0030] The frame 1 is also equipped with a pulse backflushing unit 12, which is used to blow compressed gas into the inside of the filter cartridge 62. After the filter cartridge 62 has been used for a period of time, a large amount of dust will accumulate on its surface, affecting the filtration effect. At this time, the pulse backflushing unit 12 will periodically or according to the pressure difference signal blow compressed gas into the inside of the filter cartridge 62, causing the filter cartridge 62 to expand and contract instantaneously, shaking off the dust attached to the surface of the filter cartridge 62 and letting it fall into the bottom of the dust collection chamber 54, thereby restoring the filtration performance of the filter cartridge 62.

[0031] The implementation principle of this embodiment is as follows: The dust collection unit is installed above the frame 1. A negative pressure is created inside the filter box 5 using a fan 4, causing dust-laden air to enter the filter box 5 through the inlet 51. After being filtered by the filter cartridge 62, clean air is discharged from the outlet 52, effectively collecting the dust generated during unloading and preventing dust diffusion. Simultaneously, a flexible dust curtain 11 initially blocks dust leakage, and a partition 53 divides the filter box 5 into a dust collection chamber 54 and an exhaust chamber 55, ensuring the orderly progress of the filtration process. The combination of the filter cartridge 62 and the frame 61 provides a highly efficient filtration effect. The pulse backflushing unit 12 can promptly clean the dust on the surface of the filter cartridge 62, extending its service life. Compared to traditional methods such as spray dust suppression, this method does not increase the moisture content of the material and more effectively solves the dust pollution problem, improving the air quality and material quality of the working environment.

[0032] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
