Description

Technical Field

[0001] This utility model relates to the field of ventilation system technology, specifically a ventilation auxiliary system for underground mining areas. Background Technology

[0002] A ventilation system is a building environment control technology used to improve and control indoor air quality. It controls the spread and harm of air pollutants through means such as air exchange and dilution or ventilation and exhaust, thereby ensuring the quality of indoor and outdoor air environment. A ventilation system refers to a series of equipment, devices and pipes used to achieve indoor and outdoor air exchange and circulation. It mainly includes air inlets, air outlets, air supply ducts, fans, cooling and heating equipment, filters, control systems and other auxiliary equipment.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: When carrying out underground mining, it is necessary to construct a ventilation system, in which the air intake pipes are arranged on the ground. Since most air intake pipes only have internal filtration mechanisms, a lot of dust and impurities will accumulate on the filter plates during long-term use. Due to the special installation position of the filter plates, it is easy to cause inconvenience when cleaning or replacing them. Therefore, in order to solve the above problems, an auxiliary ventilation system for underground goaf areas is proposed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a ventilation auxiliary system for underground goaf areas, with the specific technical solution as follows:

[0005] A ventilation auxiliary system for underground goaf areas includes a connecting part and a filtering device. The side wall of the connecting part is connected to two ventilation pipes, and the side wall of each ventilation pipe is connected to a connecting pipe. The upper surface of the connecting pipe is provided with a filtering device, which includes a placement box located directly above the connecting pipe. Multiple placement plates are inserted into the inner wall of the placement box, and filter plates are inserted into the inner wall of each placement plate. A storage groove is provided on the side wall of each placement plate. Pushing the placement plate causes the filter plate to be inserted into the inner wall of the placement box. When it is necessary to move the placement plate, a finger is inserted into the storage groove to pull the placement plate. By setting up the placement box, placement plates, filter plates, and storage box, air can be filtered, and the filter plates can be easily replaced.

[0006] Preferably, the side wall of the placement box is fixedly connected to two connecting plates, and a limiting block is fixedly connected to the side wall of the connecting plate near the side wall of the placement plate. The surface of the limiting block is slidably connected to the inner wall of the placement plate. When the placement plate moves, the placement plate slides on the surface of the limiting block on the connecting plate. The connecting plate and the limiting block can restrict the position of the placement plate.

[0007] Preferably, a support column is fixedly connected to the side wall of the placement box, and a rotating rod is rotatably connected to the surface of the support column. The rotating rod is located on the side wall of the placement plate, and the rotating rod rotates to the side wall of the placement plate. The support column and the rotating rod can limit the position of the placement plate.

[0008] Preferably, the rotating rod and the inner wall of the placement box are threaded together with a positioning pin. After the rotating rod rotates to a suitable angle, the positioning pin is rotated to the inner wall of the rotating rod and the placement box. The positioning pin can limit the angle of the rotating rod.

[0009] Preferably, a placement groove is provided on the surface of the placement box near the placement plate, and the placement plate is inserted into the inner wall of the placement groove of the placement box. When the placement plate moves, the placement plate is inserted into the inner wall of the placement groove of the placement box, and the placement groove can accommodate the placement plate.

[0010] Preferably, the vertical cross-section of the placement box forms an "I"-shaped structure. By setting the placement box with a special structure, the contact area between the placement box and the connecting pipe can be increased, thereby increasing stability.

[0011] Preferably, the surface of the placement box is provided with a moving device, which includes a main frame and a sub-frame. The side walls of the main frame and the sub-frame are fixedly connected to the two sides of the placement box, respectively. The surfaces of the main frame and the sub-frame are rotatably connected to two support wheels. The main frame and the sub-frame drive the support wheels to roll on the ground. By setting the main frame, the sub-frame and the support wheels, the placement box can be supported, and the placement box can be moved to a convenient position.

[0012] Preferably, a fixing plate is fixedly connected to the side wall of the connecting pipe near the main frame. Two limiting pins are threadedly connected to the inner wall of the main frame and the fixing plate. After the main frame moves to a suitable position, the limiting pins are rotated to the inner wall of the main frame and the fixing plate. The fixing plate and the limiting pins can restrict the position of the main frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This underground goaf ventilation auxiliary system involves placing the placement box on the connecting pipe, then rotating the rotating rod to make it rotate on the surface of the support column. After the rotating rod moves away from the placement plate, insert your finger into the receiving slot and pull the placement plate to pull it out of the placement box. As the placement plate moves, it will move on the surface of the limiting block on the connecting plate. After the placement plate moves to the appropriate position, insert the filter plate into the inner wall of the placement plate, then push the placement plate to insert it into the inner wall of the placement box. Then push the rotating rod to rotate it to the side wall of the placement plate, and then rotate the positioning pin into the rotating rod and the placement box. When the air flows, the air will pass through the filter plate. By setting up the entire device, the air can be filtered, and the filter plate can be easily replaced, reducing the impact on ventilation time.

[0015] 2. This underground goaf ventilation auxiliary system pushes the placement box, which in turn moves the main frame and the auxiliary frame. The main frame and the auxiliary frame then drive the support wheels to roll on the ground. The main frame and the auxiliary frame move to the surface of the connecting pipe, and then the limit pin rotates to the inner wall of the main frame and the fixed plate. When a gap appears between the placement box and the connecting pipe, a rubber sealing ring is installed on the connecting pipe. By setting the entire device, the entire filter device can be moved easily, thereby reducing the time required to replace the entire filter device. Attached Figure Description
