Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, and particularly relates to a mine ventilation device for mine safety production. Background Technique

[0002] Coal is a solid combustible mineral formed by the complex biochemical and physicochemical changes of ancient plants buried underground. A coal mine is the general term for the shafts, chambers, equipment, surface buildings and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, adits, etc. in underground mine development are also called mines. In a coal mine, a ventilation device is used to continuously supply fresh air to the mine, supply air for personnel to breathe, dilute and discharge harmful gases and floating dust, improve the underground climate conditions and control the air flow during disaster relief.

[0003] The Chinese patent application with the application number CN202021168879.8 discloses a mine ventilation device for coal mining, including a base, a first fixed seat and a second fixed seat. Two groups of shock absorption mechanisms are fixed on the surface of the base. The shock absorption mechanism includes a first shock absorption spring, a second shock absorption spring, a limiting plate, a supporting block and a fixing block. The fixing block is of a hollow structure. The inner cavity of the fixing block is engaged with a limiting plate. The limiting plate is of a disc structure. A second shock absorption spring is fixed on the surface of the limiting plate. One end of the second shock absorption spring is installed at the bottom of the inner cavity of the fixing block. A supporting block is welded on the surface of the limiting plate. This device reduces the vibration transmitted from the fixed seat through the first shock absorption spring, and uses the second shock absorption spring, the limiting plate, the supporting block and the fixing block to assist in shock absorption. Compared with sleepers, the shock absorption effect is more obvious, and the impact on the mine caused by the vibration of the fan is greatly reduced.

[0004] However, the existing mine ventilation devices still have some defects. When in use, the ventilation devices have a single function, no humidifying effect, and poor purification effect. Summary of the Utility Model

[0005] Aiming at the above deficiencies in the prior art, the utility model provides a mine ventilation device for mine safety production, and the purpose is to solve the problems such as single function, no humidifying effect and poor purification effect when the ventilation device is in use.

[0006] To achieve the above utility model purpose, the technical scheme adopted by the utility model is: a mine ventilation device for mine safety production, including a base, on the upper surface of which a box body is installed. A switch door is connected to the front side of the box body. An air suction pipe is connected to the top of the box body. A fixing frame is installed inside the box body. An installation frame is connected to the fixing frame. A ventilation slot is opened on the box body. A water storage tank is connected to the bottom of the ventilation slot. Stable mechanisms are connected to both sides of the upper surface of the base;

[0007] An atomizer is installed inside the water storage tank. One end of the atomizer is connected to an air supply pipe. An atomization rack is connected inside the ventilation slot. The bottom end of the atomization rack is communicated with a spray head. The top end of the air supply pipe is communicated with the extended end of the atomization rack. A water injection pipe is connected to one side of the water storage tank.

[0008] Furthermore, a fixing plate is connected to the inner wall of the ventilation slot. A driving motor is connected to one side of the fixing plate. The output end of the driving motor is drivingly connected to a fan. An air inlet is opened at the top end of the ventilation slot.

[0009] Furthermore, the stabilizing mechanism includes a threaded rod screwed on the base. A damping knob is fixedly connected to the bottom end of the threaded rod. The bottom end of the threaded rod is rotatably connected to a support base.

[0010] Furthermore, insertion rods are sleeved on both sides of the fixing frame. A handle is connected to one end of the insertion rod. A return spring is sleeved on the insertion rod. A limiting slot is opened at the bottom end of the fixing frame.

[0011] Furthermore, positioning holes are opened at both ends of the mounting frame. The insertion rod is inserted and connected with the positioning holes. The mounting frame is connected with a dust removal bag.

[0012] Furthermore, universal wheels are fixedly connected to the lower surface of the base. A pushing handle is connected to one side of the box body.

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

[0014] When the mine ventilation device for mine safety production of the present utility model is actually used, the device is pushed to a designated position through the pushing handle. The damping knob is rotated to drive the threaded rod to rotate, and then drive the support base to move downward to support the device. By starting the driving motor to drive the fan, a negative pressure is generated at the top of the box body, so that the dust inside the air suction pipe is filtered through the dust removal bag and then discharged through the air inlet. By starting the atomizer, the clear water inside the water storage tank is extracted and then discharged through the spray head on the atomization rack, which can humidify the filtered air, making the function of the ventilation device more diverse and improving the use effect.
