Description

Technical Field

[0001] This utility model relates to the technical field of mine ventilation equipment, specifically a replaceable explosion-proof vibration-proof adjustable damper device. Background Technology

[0002] In mining operations, the stability of the ventilation system and the precision of airflow regulation are crucial. However, traditional airlocks have shortcomings in regulating airflow and are unable to withstand the effects of underground blasting vibrations, leading to frequent damage and high maintenance costs. Therefore, developing a new type of airlock device that can both precisely regulate airflow and effectively resist blasting vibrations is of paramount importance. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a replaceable explosion-proof vibration-proof regulating damper device, which achieves precise airflow regulation and high strength, high stability, and corrosion resistance of the device.

[0004] To achieve the above technical objectives, the technical solution adopted in this application is a replaceable explosion-proof vibration regulating damper device, including a main frame, a baffle angle steel and an air regulating plate; a groove is formed between the baffle angle steel and the main frame, and the air regulating plate is detachably installed in the groove.

[0005] Furthermore, the main frame is constructed by welding together upper horizontal channel steel, lower horizontal channel steel, left vertical channel steel, and right vertical channel steel.

[0006] Furthermore, all the channel steels are made of highly corrosion-resistant steel to improve the service life of the damper device.

[0007] Furthermore, there are multiple air regulating plates, which are installed in the groove in a manner that stacks one on top of the other in the height direction of the main frame.

[0008] Furthermore, the air regulating plate is made of PP plastic, which has the advantages of being lightweight and easy to replace.

[0009] Furthermore, one end of the round steel component is embedded in the wall, and the other end is fixed to the main frame. Multiple round steel components are arranged around the main frame.

[0010] Furthermore, there are multiple angle steel components, with the left side angle steel connected to the upper transverse channel steel, the right side angle steel connected to the lower transverse channel steel, and the top arched angle steel connected to the upper transverse channel steel, to improve the stability of the device.

[0011] Furthermore, the steel plate component is connected to the main frame, left side angle steel, right side angle steel, and top arched angle steel by welding.

[0012] Furthermore, the steel plate component can be assembled and welded from multiple small steel plates to ensure the stability and tightness of the device.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Precise airflow adjustment

[0015] Traditional damper adjustment methods are often limited by structural design or inconvenient operation, making it difficult to precisely control airflow. This damper device adopts an embedded air regulating plate design, which can achieve more precise and flexible airflow adjustment by increasing or decreasing the number of air regulating plates, meeting the ventilation needs of different working conditions in the mine.

[0016] 2. Excellent shock resistance, able to adapt to harsh environments.

[0017] The underground mining environment is frequently affected by blasting vibrations, and traditional air doors are easily damaged by these vibrations. To solve this problem, the ventilation plate of this device is made of PP plastic, which has excellent shock-absorbing properties, enabling it to remain stable under strong blasting vibrations and avoid damage caused by vibration. Meanwhile, traditional air doors often rust or corrode due to prolonged exposure to humid and corrosive environments, leading to frequent replacements. The ventilation plate of this device effectively resists the erosion of underground moisture, corrosive gases, and mine dust, extending the service life of the device and reducing long-term maintenance costs.

[0018] 3. Sturdy structure and strong sealing performance

[0019] The main frame of this device is welded from four channel steels, resulting in a compact and stable structure. Multiple angle steels are welded to the main frame, and multiple round steels are fixed with anchoring agents to ensure that the air doors are not easily loosened or displaced during blasting vibrations underground, reducing ventilation problems caused by loosening or damage to the device.

[0020] 4. Convenient replacement and maintenance

[0021] The air regulating plate of this damper device adopts an embedded design, which has the advantage of easy replacement. During the use of the damper, if the air regulating plate is damaged or the air volume needs to be adjusted, technicians only need to simply remove the damaged air regulating plate and replace it, avoiding cumbersome disassembly and maintenance procedures.

[0025] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Example

[0026] This utility model relates to a replaceable explosion-proof vibration regulating damper device, which is particularly suitable for damp, corrosive environments such as underground mines that are frequently affected by blasting vibrations. The device mainly includes the following components: round steel 9, upper transverse channel steel 15, lower transverse channel steel 1, left vertical channel steel 7, right vertical channel steel 5, left side angle steel 8, right side angle steel 4, top arched angle steel 6, baffle angle steel 13, steel plate 10, and air regulating plate 11.

[0027] The main frame is constructed by welding together an upper transverse channel steel 15, a lower transverse channel steel 1, a left vertical channel steel 7, and a right vertical channel steel 5. The upper transverse channel steel 15 is located at the top of the device with its groove facing upwards; the lower transverse channel steel 1 is located at the bottom of the device with its groove facing downwards; the left vertical channel steel 7 and the right vertical channel steel 5 are located on the left and right sides of the device, respectively, with their grooves facing left and right. All four channel steels have a diameter of 14mm and are made of highly corrosion-resistant steel, effectively resisting the erosion of underground moisture, corrosive gases, and mine dust, thus extending the service life of the device.

[0028] The angle steel components include left-side angle steel 8, right-side angle steel 4, top arched angle steel 6, and baffle angle steel 13, arranged around the main frame and connected to the main frame by welding. The baffle angle steel 13 connects to the left-side vertical channel steel 7 and the right-side vertical channel steel 5, forming a groove for placing the air regulating plate 11. The bottom of the baffle angle steel 13 is filled with poured concrete. The left-side angle steel 8 is vertically arranged on the left side, connected at the top to the upper horizontal channel steel 15 and at the bottom to the lower horizontal channel steel 1; the right-side angle steel 4 is vertically arranged on the right side, connected at the top to the upper horizontal channel steel 15 and at the bottom to the lower horizontal channel steel 1; the top arched angle steel 6 is located above the upper horizontal channel steel 15 and connected to the left and right sides of the upper horizontal channel steel 15. The connection between the angle steel and the channel steel enhances the stability of the device and effectively reduces the impact force from blasting in the mine.

[0029] The system consists of nine round steel bars (9 in total): three at the top, two on the left side, two on the right side, and two at the bottom. These bars are arranged around the main frame to secure it and the entire damper. The top three round steel bars are welded at one end to the upper horizontal channel steel 15, with the other end extending at least 30cm into the wall. The portion extending into the wall needs to be secured with anchoring agent. The two round steel bars on the left side are welded at one end to the left vertical channel steel 7, with the other end extending at least 30cm into the wall. The portion extending into the wall needs to be secured with anchoring agent. The two round steel bars on the right side are welded at one end to the right vertical channel steel 5, with the other end extending at least 30cm into the wall. The portion extending into the wall needs to be secured with anchoring agent. The two round steel bars at the bottom are welded at one end to the lower horizontal channel steel 1, with the other end extending at least 30cm into the wall. The portion extending into the wall needs to be secured with anchoring agent. The addition of anchoring agent effectively secures the round steel bars, preventing them from loosening from the wall and avoiding injury from falling round steel bars.

[0030] The steel plate component 10 is arranged around the main frame and connected to the main frame, the left side angle steel 8, the right side angle steel 4, and the top arched angle steel 6. The steel plate component 10 is close to the edge of the tunnel 3 to reduce air leakage. Since the shape and size of the tunnel 3 may vary, the steel plate component 10 can be assembled by welding multiple pieces together to ensure stability and tightness.

[0031] The air regulating plate 11 is used to adjust the air volume and is placed in the groove formed by the baffle angle steel 13, the left vertical channel steel 7, and the right vertical channel steel 5. Multiple air regulating plates 11 are installed in the groove in a stacked manner along the height of the main frame. When an increase in air volume is needed, the number of air regulating plates 11 can be reduced; when a decrease in air volume is needed, the number of air regulating plates 11 can be increased, achieving fine adjustment of the air volume. The dimensions of the air regulating plate 11 are 30*200*2300mm, the adjustment area width is 2.3m, and the height is determined according to the site conditions and ventilation volume. The bottom of the air regulating plate 11 is concrete 15. The air regulating plate 11 is made of plastic PP sheet, which allows it to remain stable under strong blasting vibrations and avoid damage caused by vibration. Meanwhile, traditional air dampers often rust or corrode due to prolonged exposure to humid and corrosive environments, leading to frequent replacements. The air regulating plate 11 of this device can effectively resist the erosion of underground moisture, corrosive gases, and mine dust, extending the service life of the device and reducing long-term maintenance costs. Even if the air regulating plate 11 is damaged, technicians only need to simply remove the damaged air regulating plate 11 and replace it, avoiding cumbersome disassembly and maintenance procedures.
