Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection technology for conveying equipment, and more specifically to a dynamic enclosure device for conveying equipment. Background Technology
[0002] To reduce pollution of the surrounding environment from materials on conveying equipment and to prevent external factors such as wind and rain from exacerbating pollution, conveying equipment needs to be enclosed. Currently, commonly used enclosure methods for conveying equipment are static enclosures, mainly including covers, windbreaks, and enclosed corridors. Some conveying equipment has functions such as loading and unloading in the middle, which is difficult to achieve with conventional enclosure devices, leading to dust pollution and other problems. To solve these problems, some dynamic enclosure technologies have emerged, but their implementation is limited, requiring new designs that meet environmental protection requirements.
[0003] For example, Chinese invention patent CN 108147146 B discloses a closed transfer facility adapted to the operation of a bridge grab unloader, including a feeding belt conveyor, a first guide chute, a cover, a transfer hopper, a second guide chute, steel supports, a dock conveyor, a conveyor belt, and a head frame; the feeding belt conveyor has a first guide chute at one end and extends into the transfer hopper at the other end, with a cover above it; the second guide chute is located at the bottom of the transfer hopper and is above the dock conveyor; the dock conveyor is arranged on the dock viaduct, with steel supports on both sides; the conveyor belt is placed on the steel supports and the head frame, laid above the dock conveyor, forming a cover over it; all dust is contained within the cover and the covering conveyor belt, preventing it from escaping into the air, thus improving environmental protection. However, this system is only suitable for scenarios with small loading or unloading facilities, such as bridge grab unloaders. For scenarios with larger loading or unloading facilities, such as ship loaders, the form in this patent is difficult to implement. Some similar actual operation cases have reported that the installation of multiple redirecting rollers has caused the covering tape to frequently deviate. Summary of the Invention
[0004] In order to overcome the above-mentioned technical defects in the existing technology, the purpose of this utility model is to provide a dynamic sealing device for conveying equipment. The device uses a winding device installed on a movable support device to achieve the winding and unwinding of the covering belt, thereby avoiding the problem of conveying equipment being difficult to seal due to movable loading and unloading devices, and effectively meeting environmental protection requirements.
[0005] The solution adopted in this utility model is as follows:
[0006] This utility model provides a dynamic enclosure device for conveying equipment, including a conveying device with a movable support device that moves along the length of the conveying device. A belt winding device is mounted on the movable support device, and a cover belt is mounted on the belt winding device. Cover belt supports and baffles are provided on both sides of the conveying device; the cover belt is supported by the cover belt supports. During operation, the movable support device moves under its own power. In sections requiring openness, the cover belt can be wound around the belt winding device, achieving partial opening of the conveying device; in sections requiring closure, the cover belt can be released from the belt winding device onto the cover belt supports, achieving closure of the conveying device. This allows for the arbitrary switching between closed and open sections during loading and unloading of the conveying device.
[0007] Preferably, the covering strip is equipped with an anti-deviation device.
[0008] In any of the above embodiments, it is preferred that the end of the movable support device is provided with a guide device.
[0009] In any of the above embodiments, it is preferred that one end of the covering tape is fixed to the tape winding device and can be wound on the tape winding device; the other end of the covering tape is fixed to an end fixing device located at the end of the conveying equipment.
[0010] In any of the above embodiments, preferably, the winding device has winding power, the winding speed of the winding device varies with the moving speed of the movable support device; the winding speed of the winding device varies with the radius of the cover tape wound on the winding device; the winding speed of the winding device varies with the tension of the cover tape, and the winding device tightens the cover tape.
[0011] In any of the above embodiments, it is preferred that the movable support device includes a bracket with support wheels; the movable support device is mounted on both sides of the conveying equipment via the bracket, and the two do not contact each other.
[0012] In any of the above embodiments, it is preferred that the conveying equipment includes a belt conveyor, a plate conveyor, a scraper conveyor, a screw conveyor, and a roller conveyor.
[0013] In any of the above embodiments, it is preferred that the dynamic enclosure device of the conveying equipment can be applied to a ship loader or a ship unloader, which can move along the length of the conveying equipment.
[0014] In any of the above embodiments, it is preferred that the ship unloader is equipped with a discharge chute; the ship unloader is equipped with two belt winding devices, which are located on both sides of the discharge chute respectively.
[0015] In summary, the dynamic sealing device for conveying equipment of this utility model has the following advantages: The winding and unwinding of the covering belt is achieved through a winding device installed on a movable support device, thereby realizing the closure and opening of different sections. This avoids the problem of difficulty in sealing the conveying equipment due to movable loading and unloading devices, effectively meeting environmental protection requirements. Furthermore, the dynamic sealing device of this utility model can be applied to ship loaders or ship unloaders, which can move along the length of the conveying equipment, replacing the movable support device and thus having a wider range of applications.

[0025] The following description is merely exemplary and not intended to limit this disclosure, its application, or its uses. The specific embodiments of the dynamic enclosure device for conveying equipment of this utility model are further described below with reference to the accompanying drawings.
[0026] like Figure 1-3 The diagram shows a preferred embodiment of the dynamic sealing device for conveying equipment according to this utility model. The dynamic sealing device for conveying equipment includes a conveying device 1. The conveying device 1 is provided with a movable support device 6 that moves along the length of the conveying device. A belt winding device 5 is provided on the movable support device 6, and a covering belt 2 is provided on the belt winding device 5. In this embodiment, covering belt supports 3 and baffles 4 are provided on both sides of the conveying device 1; the covering belt 2 is supported by the covering belt supports 3.
[0027] Due to the movable loading and unloading devices, the conveying equipment cannot be fully enclosed; some sections need to be open, and these non-enclosed sections are dynamic. Through the aforementioned functions, the cover belt 2 and the baffle 4 form an enclosed space to prevent dust leakage. In sections requiring openness, the cover belt 2 can be wound onto the winding device 5, allowing the conveying equipment 1 to be partially open; in sections requiring enclosure, the cover belt 2 can be released from the winding device 5 onto the cover belt support 3, achieving enclosure of the conveying equipment.
[0028] In this embodiment, the covering belt 3 is provided with an anti-deviation device 8 to prevent the covering belt 2 from deviating during operation.
[0029] In this embodiment, the end of the movable support device 6 is provided with a guide device 9, which guides the covering strip 2.
[0030] In this embodiment, one end of the covering tape 2 is fixed to the winding device 5 and can be wound on the winding device 5; the other end of the covering tape 2 is fixed to the end fixing device 7 located at the end of the conveying device 1.
[0031] In this embodiment, the winding device 5 has winding power, and the winding speed of the winding device 5 varies with the moving speed of the movable support device 6; the winding speed of the winding device 5 varies with the radius of the covering tape 2 wound on the winding device 5; the winding speed of the winding device 5 varies with the tension of the covering tape 2, and the winding device 5 tightens the covering tape 2.
[0032] In this embodiment, the movable support device 6 includes a bracket with support wheels; the movable support device 6 is mounted on both sides of the conveying device 1 by the bracket, and the two do not contact each other, thereby making the movable support device 6 more widely applicable.
[0033] In this embodiment, the conveying equipment 1 includes a belt conveyor, a plate conveyor, a scraper conveyor, a screw conveyor, and a roller conveyor.
[0034] like Figure 4-5 The diagram shows a structural schematic of another preferred embodiment of the dynamic sealing device for conveying equipment according to this utility model. This example is an embodiment of this utility model on a ship loader. It includes a ship loader 10 and a conveying device 1. The ship loader 10 can move along the length of the conveying device 1. The ship loader 10 is equipped with a winding device 5, and a covering belt 2 is provided on the winding device 5. Covering belt supports 3 and baffles 4 are provided on both sides of the conveying device 1; the covering belt 2 is supported by the covering belt supports 3. During operation, the ship loader 10 moves by its own power. In the section where the ship loader 10 moves, the covering belt 2 can be wound around the winding device 5, achieving partial opening of the conveying device 1; in the section on the right side of the ship loader 10 in the figure, the conveying device 1 carries material, and the covering belt 2 can be released from the winding device 5 onto the covering belt supports 3, achieving sealing of the conveying device; Figure 4 The section to the left of the ship loader 10 no longer needs to be closed because the material has already been loaded onto the ship and the conveyor equipment 1 no longer carries any material. Through the above mechanism, the conveyor equipment 1 is dynamically closed: it is open in the section where the ship loader 10 moves, closed in the section where the conveyor equipment 1 carries material, and remains open in the section where the conveyor equipment 1 does not carry material.
[0035] like Figure 6-7 The diagram shows a structural schematic of another preferred embodiment of the dynamic enclosure device for conveying equipment according to this utility model. This example is an embodiment of this utility model on a ship unloader. It includes a ship unloader 11 and a discharge chute 12, the discharge chute 12 being located on the ship unloader 11. The ship unloader 11 can move along the length of the conveying equipment 1. The ship unloader 11 is equipped with a belt winding device 5, and a cover belt 2 is provided on the belt winding device 5. If both sides of the conveying equipment 1 of the ship unloader 11 have the potential to carry materials, then two belt winding devices 5 need to be installed on the ship unloader 11, respectively located on both sides of the discharge chute 12; if one side of the ship unloader 11 has the potential to carry materials, and the other side does not, then one belt winding device 5 needs to be installed on the ship unloader 11, located on one side of the discharge chute 12. Cover belt supports 3 and baffles 4 are provided on both sides of the conveying equipment 1; the cover belt 2 is supported by the cover belt supports 3. During operation, the unloader 11 moves under its own power, and the unloading chute 12 moves with it. In the section where the unloading chute 12 moves, the covering belt 2 can be wound onto the winding device 5, thus partially opening the conveyor equipment 1. Figure 6In the sections on both sides of the ship unloader 11, the conveying equipment 1 carries materials. The covering belt 2 can be released by the belt winding device 5 onto the covering belt support 3 to achieve the closure of the conveying equipment. Through the above mechanism, the conveying equipment 1 is dynamically closed, with the sections where the ship unloader 11 and the unloading chute 12 have moved open, and the sections on both sides of the unloading chute 12 closed.
