Embodiment Construction
[0024] combine Figure 1 to Figure 5 As shown, the specific implementation of the anti-leakage device and method for a wall belt belt provided by the present invention will be described.
[0025] An anti-leakage device for a wall-penetrating belt specifically includes a base 1, a bracket 2, a movable baffle 3, a lower baffle 4, a first push-pull cylinder 5, a second push-pull cylinder 6, and a third push-pull cylinder 7, and the anti-leakage device for a wall-penetrating belt The whole body is inlaid on the air door 8, and the belt of the belt conveyor passes through the air door 8 through the wall-penetrating belt anti-leakage device. The support 2 is rectangular as a whole, including uprights on both sides and cross-columns above, the uprights are used to fix the movable baffle, the cross-columns are used for the fixed connection of the whole device and the damper, and the bracket can be made of channel steel or I-beam material. The base 1 is fixedly arranged below the supp...

The invention provides a wall-through belt air leakage prevention device and a wall-through belt air leakage prevention method, and relates to the technical field of mine ventilation safety. The wall-through belt air leakage prevention device comprises a base, a support, a movable baffle, a lower baffle, a first push-pull cylinder, a second push-pull cylinder and a third push-pull cylinder, wherein the support is fixed on the base; the first push-pull cylinder and the second push-pull cylinder are horizontally arranged along the movable baffle; one end of the third push-pull cylinder is hingedto a rotating shaft of the lower baffle, and the other end of the third push-pull cylinder is hinged to a mounting supporting seat; an upper belt passing space is reserved between the movable baffleand the lower baffle; and a lower belt passing space is reserved between the lower baffle and the base. The wall-through belt air leakage prevention method is characterized in that the wall-through belt air leakage prevention device is installed on an air door, and the shape of the movable baffle is adjusted according to the working states of idling, stopping and conveying of coal gangue and the like of the belt so as to prevent air leakage at the position of the air door. The wall-through belt air leakage prevention device and the wall-through belt air leakage prevention method solve the problem of air leakage when a belt passes through the air door, and have the advantages of being simple in structure, convenient to install, flexible in control and the like.
Description
technical field [0001] The invention relates to the technical field of mine ventilation safety, in particular to an air leakage prevention device for a wall-penetrating belt and a method for preventing air leakage from a damper by using the air-leakage prevention device for a wall-penetrating belt. Background technique [0002] Mine ventilation structures can be divided into: ventilation structures that pass the wind flow, including ventilator ducts, anti-wind devices, wind bridges, wind deflectors, and windshield adjustment windows, etc.; Curtains and dampers. In the mine ventilation system, it is necessary to set up a damper at the position where it is necessary to cut off the wind flow and allow pedestrians, traffic or belts to pass. When the coal mine underground belt conveyor passes through the damper, due to the large cross-section, it often causes the problem of air leakage from the damper. Mine air leakage is an important cause of coal spontaneous combustion in goa...
