[0039] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] like Figure 1 As shown, according to the first aspect of the embodiment of the present disclosure, an exhaust device is proposed, including: an air collecting section 110, the air collecting section 110 is used to cover the belt conveyor 200 located in the belt conveyor corridor 300, and the air collecting section 110 is used to collect water vapor generated by the materials located in the belt conveyor 200; an exhaust duct 200 is used to pass through the side wall of the belt conveyor corridor 300, one end of the exhaust duct 200 is connected to the air collecting section 110, and the other end of the exhaust duct 200 is connected to the external environment of the belt conveyor corridor 300.

[0041] The exhaust device proposed according to the embodiment of the present disclosure includes an air collecting section 110 and an exhaust duct 200, wherein one end of the exhaust duct 200 is connected to the air collecting section 110. In actual application, the air collecting section 110 is covered on the belt conveyor 200, and the exhaust duct 200 is passed through the side wall of the belt conveyor corridor 300. The air collecting section 110 can collect water vapor generated by the materials on the belt conveyor 200. As the water vapor increases, the gas pressure inside the air collecting section 110 increases, and a negative pressure difference is generated between the inside of the air collecting section 110 and the atmosphere. Under the action of the negative pressure, the water vapor will flow from the air collecting section 110 into the exhaust duct 200, and the other end of the exhaust duct 200 is connected to the external environment of the belt conveyor corridor 300, so that the water vapor can be discharged into the external environment of the belt conveyor corridor 300 in accordance with the exhaust duct 200, thereby preventing the water vapor from diffusing inside the belt conveyor corridor 300.

[0042] It can be understood that a belt conveyor equipment 200 is provided inside the belt conveyor corridor 300. The belt conveyor equipment 200 is used to transport materials. Some materials have a higher temperature and a higher water content, which causes a large amount of water vapor to be generated by the materials during the transportation process of the belt conveyor equipment 200. The air collecting section 110 is covered on the belt conveyor equipment 200, so that the materials can be covered by the air collecting section 110, which is more conducive to the air collecting section 110 to collect the water vapor generated by the materials.

[0043] It is understandable that the air inlet of the exhaust pipe 200 can be set at the top of the air collecting part 110, which is more conducive to the water vapor generated by the material entering the exhaust pipe 200 and is conducive to improving the emission efficiency of the water vapor.

[0044] It can be understood that the exhaust duct 200 is passed through the side wall of the belt transport corridor 300, which is helpful to reduce the probability of rainwater entering the exhaust duct 200 in rainy weather, and can avoid a large amount of rainwater from pouring into the exhaust duct 200 and affecting the quality of the material.

[0045] It should be noted that in traditional technology, an exhaust port is often set at the top of the belt transport corridor 300 and water vapor is removed by an exhaust fan. This method has a low efficiency in removing water vapor, and a large amount of water vapor will still diffuse inside the belt transport corridor 300, causing a great impact on the on-site working environment. On the one hand, it will hinder the sight of the on-site staff, thus posing certain safety hazards. On the other hand, water vapor will cause severe corrosion to the on-site steel structure, such as the structural frame of the belt transport corridor 300 and the frame of the belt transport equipment 200, resulting in a high investment in on-site steel structure anti-corrosion costs. At the same time, the exhaust fan is also easily affected by water vapor corrosion and fails, resulting in certain spare parts consumption costs. Compared with the traditional technology, the exhaust device proposed in the embodiment of the present invention, based on the above-mentioned setting, can directly discharge water vapor to the outside of the belt transport corridor 300, with high exhaust efficiency, and can prevent water vapor from diffusing inside the belt transport corridor 300, thereby ensuring that the staff has a wide field of vision inside the belt transport corridor 300, reducing the corrosion of the steel structure on site by water vapor, increasing the service life of the steel structure on site, and reducing the investment in corrosion protection of the steel structure on site. At the same time, the exhaust device no longer needs to be equipped with an exhaust fan, which can further reduce the investment in equipment resources and save the electricity resources consumed by the exhaust fan.

[0046] Exemplarily, the exhaust pipe 200 may be made of corrosion-resistant materials, such as polyvinyl chloride, polypropylene, polytetrafluoroethylene, etc., which can increase the service life of the exhaust pipe 200.

[0047] In some examples, such as Figure 1 As shown, the air collecting part 110 includes: a mounting member 111, the exhaust pipeline 200 is arranged on the mounting member 111, the mounting member 111 is provided with an air vent, and the air vent is connected to the exhaust pipeline 200; a bracket 112, one end of the bracket 112 is connected to the mounting member 111, and the other end of the bracket 112 is used to be connected to the frame of the belt conveyor 200; a sealing member 113, which is arranged on the mounting member 111, the sealing member 113 is used to overlap the belt conveyor 200, and the sealing member 113 encloses an air collecting space, and the air collecting space is used to collect water vapor generated by the material located on the belt conveyor 200.

[0048] In the above technical scheme, the air collecting part 110 includes a mounting member 111, a bracket 112 and a sealing member 113, wherein one end of the bracket 112 is arranged on the frame of the belt conveyor 200, and the other end is connected to the mounting member 111, so that the mounting member 111 can be arranged on the frame of the belt conveyor 200 through the bracket 112, and the sealing member 113 is arranged on the mounting member 111, and the sealing member 113 and the belt conveyor 200 are connected in an overlapping manner, and the sealing member 113 surrounds an air collecting space, and the air collecting space can be used to collect water vapor. In actual application, the belt conveyor 200 is below the air collecting space, and the mounting member 111 is above the air collecting space. A vent connected to the exhaust pipe 200 is opened on the mounting member 111, so that the water vapor generated by the material transported by the belt conveyor 200 can directly enter the air collecting space, and then enter the exhaust pipe 200 from the vent, and the water vapor is discharged to the outside of the belt conveyor corridor 300 through the exhaust pipe 200.

[0049] It can be understood that by overlapping the sealing member 113 on the belt conveyor 200, the probability of water vapor escaping can be reduced.

[0050] It is understandable that the mounting member 111 may be a plate member or a cover member with gathering ability, and no further limitation is made here.

[0051] It is understandable that, since the belt conveyor 200 is relatively long, the mounting member 111 is composed of a plurality of mounting parts connected in sequence, and an integrally formed structure may also be adopted. A plurality of brackets 112 may be provided, and the plurality of brackets 112 are arranged at intervals along the extension direction of the belt conveyor 200 .

[0052] For example, the mounting member 111 may be

[0053] In some examples, seal 113 is used to close or open the plenum space.

[0054] In the above technical solution, the seal 113 can be used to close or open the gas collecting space. During daily operations, the seal 113 can be used to close the gas collecting space, which is beneficial to the discharge of water vapor. When it is necessary to check the materials transported on the belt conveyor 200, the gas collecting space can be opened through the seal 113 to facilitate the staff to observe the materials. During daily maintenance, the gas collecting space can be opened through the seal 113 to facilitate the staff to maintain the belt conveyor 200.

[0055] In some examples, such as Figure 1 As shown, the seal 113 is made of a flexible material, and the seal 113 and the belt conveyor 200 are interference-fitted.

[0056] In the above technical solution, the seal 113 is made of a flexible material. When the air collecting space needs to be closed, the seal 113 can be naturally hung down and overlapped on the belt conveyor 200. When the air collecting space needs to be opened, the seal 113 can be lifted up to open the air collecting space. The interference fit between the seal 113 and the belt conveyor 200 can ensure the sealing degree between the seal 113 and the belt conveyor 200, which is beneficial to reduce the probability of water vapor escaping from between the seal 113 and the belt conveyor 200. At the same time, since the belt on the belt conveyor 200 is in motion during transportation, a certain overlap margin of the seal 113 can also leave a margin for the wear of the seal 113, so as to ensure that the seal 113 can maintain a sealed state against water vapor for a long time.

[0057] It is understandable that the seal 113 is made of flexible material. When the belt conveyor 200 needs to be inspected, the seal 113 can be lifted above the mounting member 111 so that the air collecting space along both sides of the belt conveyor 200 can be completely open, making it easier for the staff to carry out inspections.

[0058] For example, there may be a plurality of seals 113 , and the plurality of seals 113 are overlapped in sequence, so that it is more convenient for the staff to operate.

[0059] In some examples, such as Figure 1 As shown, the exhaust pipeline 200 has a first exhaust section 121 and a second exhaust section 122, and the two ends of the first exhaust section 121 are respectively connected to the air collecting section 110 and the second exhaust section 122. The position height of the second exhaust section 122 is higher than the position height of the air collecting section 110, and there is an inclination angle of 5° to 10° between the second exhaust section 122 along the conduction direction and the horizontal direction.

[0060] In the above technical solution, the exhaust pipeline 200 has a first exhaust section 121 and a second exhaust section 122. The second exhaust section 122 is inserted on the side wall of the belt transport corridor 300. The first exhaust section 121 is arranged between the second exhaust section 122 and the air collecting section 110, and the second exhaust section 122 and the air collecting section 110 are connected through the first exhaust section 121. The position height of the second exhaust section 122 is higher than the position height of the air collecting section 110, that is, the first exhaust section 121 has a certain height along the height direction. On the one hand, it can be beneficial to the upward discharge of water vapor. On the other hand, it can ensure that the second exhaust section 122 can have a certain position height, so that space for easy movement of staff can be reserved below the second exhaust section 122.

[0061] It can be understood that when water vapor is discharged through the exhaust pipe 200, part of the water vapor will condense into liquid condensed water when it contacts the pipe wall of the exhaust pipe 200. The second exhaust section 122 has an inclination angle of 5° to 10° between the conduction direction and the horizontal direction, which can facilitate the condensed water after the condensation of the water vapor to flow out of the exhaust pipe 200.

[0062] Exemplarily, the position height of the air inlet of the second exhaust section 122 is higher than the position height of the air outlet of the second exhaust section 122, so that condensed water can be discharged to the outside of the belt transport corridor 300 under the action of gravity, and a condensed water collection device can be correspondingly arranged outside the belt transport corridor 300; it can be understood that when the position height of the air inlet of the second exhaust section 122 is higher than the position height of the air outlet of the second exhaust section 122, the second exhaust section 122 is adopted with an inclination angle of 5° to 10° between the conducting direction and the horizontal direction. On the one hand, it can ensure that the condensed water can flow out of the exhaust pipe 200 under the action of gravity, and on the other hand, it can also ensure that the water vapor can be discharged smoothly, and at the same time, it can avoid the reflux of water vapor due to excessively large angles.

[0063] Exemplarily, the first exhaust section 121 is disposed vertically.

[0064] In some examples, such as Figure 1 As shown, the position height of the air outlet of the second exhaust section 122 is higher than the position height of the air inlet of the second exhaust section 122 .

[0065] In the above technical solution, the position height of the air outlet of the second exhaust section 122 is higher than the position height of the air inlet of the second exhaust section 122, so that the condensed water can flow back to the belt conveyor 200 under the action of gravity. Since the condensed water is generated from the water vapor of the material, the amount of condensed water is small and after flowing back to the material, it will be transported away with the material, so that the amount of condensed water mixed with the material is small and does not affect the quality of the material. At the same time, the position height of the air outlet of the second exhaust section 122 is higher than the position height of the air inlet of the second exhaust section 122, which is also more conducive to the water vapor rising and discharging along the second exhaust section 122.

[0066] It should be noted that in winter, the external ambient temperature is relatively low. If condensed water is discharged to the outside of the belt transport corridor 300, it is easy to form ice cones, and the falling of the ice cones may pose a safety hazard. In the above technical solution, the condensed water is allowed to flow back to the belt transport equipment 200, which can reduce the probability of the condensed water coming into contact with the external cold air, thereby reducing the probability of the condensed water freezing.

[0067] It can be understood that when the position height of the air outlet of the second exhaust section 122 is higher than the position height of the air inlet of the second exhaust section 122, the second exhaust section 122 is inclined at an angle of 5° to 10° between the conduction direction and the horizontal direction. On the one hand, it can ensure that the condensed water can flow back to the belt conveyor 200 under the action of gravity, and on the other hand, it can also avoid a large amount of rainwater from entering the second exhaust section 122 due to the excessive size of the air outlet in rainy weather.

[0068] In some examples, such as Figure 1 As shown, it also includes: a support part 300 used to be set on the frame of the belt conveyor 200, and the exhaust pipeline 200 is set on the support part 300.

[0069] In the above technical solution, the exhaust device also includes a support portion 300, which is arranged on the frame of the belt conveyor 200, and the exhaust pipeline 200 is arranged on the support portion 300, so that the support portion 300 can provide a stable supporting force for the exhaust pipeline 200 to ensure the structural stability of the exhaust pipeline 200.

[0070] In some examples, such as Figure 1 As shown, the support portion 300 includes: a support member 131, one end of the support member 131 is used to be set on the frame of the belt conveyor 200, and the other end of the support member 131 is connected to the exhaust pipe 200; a connecting member 132, one end of the connecting member 132 is connected to the support member 131, and the other end of the connecting member 132 is connected to the exhaust pipe 200; wherein, the number of the connecting members 132 is multiple, and along the extension direction of the support member 131, the multiple connecting members 132 are arranged at intervals on the support member 131.

[0071] In the above technical solution, the support part 300 includes a support member 131 and a connecting member 132, wherein one end of the support member 131 is arranged on the frame of the belt conveyor 200, and the other end is connected to the exhaust pipe 200, one end of the connecting member 132 is connected to the support member 131, and the other end of the connecting member 132 is also connected to the exhaust pipe 200, so that a frame structure can be formed between the connecting member 132, the support member 131 and the exhaust pipe 200, which is beneficial for the support part 300 to provide stable supporting force to the exhaust pipe 200.

[0072] It is understandable that, along the extension direction of the support member 131 , a plurality of connectors 132 are spaced apart on the support member 131 , which can further improve the connection strength between the support member 131 and the exhaust pipe 200 and ensure the connection stability of the exhaust pipe 200 .

[0073] In some examples, a plurality of exhaust pipes 200 are arranged at intervals in the air collecting portion 110 .

[0074] In the above technical solution, a plurality of exhaust pipes 200 are arranged at intervals on the gas collecting portion 110 , so that water vapor can be discharged from the plurality of exhaust pipes 200 at the same time, which is beneficial to improving the discharge efficiency of water vapor.

[0075] Exemplarily, along the extending direction of the belt conveyor 200 , a plurality of exhaust ducts 200 are evenly spaced apart on the air collecting portion 110 .

[0076] like Figure 1 As shown, according to the second aspect of the embodiment of the present disclosure, a belt conveyor corridor system is proposed, including: an exhaust device as proposed in any one of the first aspects above; a belt conveyor equipment 200, the exhaust device cover is arranged on the belt conveyor equipment 200; a belt conveyor corridor 300, and the belt conveyor equipment 200 is arranged inside the belt conveyor corridor 300.

[0077] Since the belt transport corridor system provided by the embodiment of the present disclosure includes the exhaust device proposed in any one of the first aspects above, it has all the beneficial effects of the exhaust device and will not be elaborated here.
