Problems solved by technology

[0002] In the process of mine operation, it is easy to generate dust. As time goes by, the dust floats with the mine passage, and it is not easy to be taken out of the mine by the exhaust system. At the same time, it is easy to block the exhaust pipe. The traditional mine dust reduction method is at the top or The side wall is equipped with an atomizing nozzle. The water mist of the atomizing nozzle combines with the floating dust in the air and then settles, which has a good dust reduction effect. A lot of sewage and sludge are formed, polluting mine passages and affecting normal mine operations, and more work is required for the discharge of sewage and the cleaning of sludge, and even the accumulated sewage and sludge have potential safety hazards

Embodiment 1

[0023] see Figure 1-3 , in an embodiment of the present invention, a mine dust suppression mechanism includes a device body; the device body includes an outer shell 1, and the outer shell 1 is a flat hollow rectangular box, which is conveniently arranged on the inner wall of the mine passage and occupies a small area. It does not affect the installation of other equipment; the outer casing 1 is nested with a dust suppression box 2, and the dust suppression box 2 is nested with a wind collection hood 3, and the wind collection hood 3 is connected to the air inlet pipe of the blower 7 through the suction pipe 6, The front end of the wind-collecting hood 3 is provided with a dust-proof net 4 to prevent dust from entering the wind-collecting hood 3; the air outlet pipe of the blower 7 is connected to a swing tube 8, and the upper end of the swing tube 8 is connected to an air outlet cover 9; specifically, by starting Blower 7, the blower 7 has a suction effect on the gas in the w...

Embodiment 2

[0027] see Figure 3-5 The difference between this embodiment and Embodiment 1 is that in order to improve the effect of blowing the floating dust, a swing cylinder 8 is provided, and the swing cylinder 8 realizes multi-angle blowing of the floating dust by swinging, so that the floating dust enters the formed circulating air flow, Ensure the floating dust collection effect; the swing cylinder 8 is connected with a driving mechanism; the swing cylinder 8 includes a fixed cylinder 801, which is a horizontal cylinder with an open top, and the fixed cylinder 801 is fixedly connected to the top plate of the outer shell 1, The outer side of the fixed cylinder 801 is covered with a rotating cylinder 802. The rotating cylinder 802 is slidingly connected with the fixed cylinder 801. The rotating cylinder 802 is a cylinder with openings at both ends. The upper end of the rotating cylinder 802 is connected with the air outlet cover 9; The connection plate is fixedly connected with a con...

Abstract

The invention discloses a mine dust falling mechanism. The mine dust falling mechanism comprises a device body, wherein the device body comprises an outer shell, a dust falling box is nested in the outer shell, an air collecting hood is nested in the dust falling box, and the air collecting hood is in communication with an air inlet pipe of an air blower through a suction pipe; the air blower is in communication with a swing cylinder, and the upper end of the swing cylinder is in communication with an air outlet hood; the top plate of the dust falling box is fixedly connected with atomizing nozzles which are longitudinally and equidistantly distributed, and the bottom of the dust falling box is in communication with a sewage discharge pipe. By arranging a gas circulation mechanism comprising the air collecting hood, the air blower, the swing cylinder and the air outlet hood which are sequentially communicated, the circulation of airflow in the mine is realized, the floating dust is conveniently circulated and collected, and the collecting effect is relatively high; and the dust falling box internally nested with the air collecting hood and the atomizing nozzles is arranged, the collected floating dust is atomized and settled and is concentrated discharged through the sewage discharge pipe, the sedimentation effect is good, the sewage is concentrated discharged, and the internalworking environment of the mine is prevented from being polluted.

Description

technical field [0001] The invention relates to the field of mine mechanical equipment, in particular to a mine dust suppression mechanism. Background technique [0002] In the process of mine operation, it is easy to generate dust. As time goes by, the dust floats with the mine passage, and it is not easy to be taken out of the mine by the exhaust system. At the same time, it is easy to block the exhaust pipe. The traditional mine dust reduction method is at the top or The side wall is equipped with an atomizing nozzle. The water mist of the atomizing nozzle combines with the floating dust in the air and then settles, which has a good dust reduction effect. More sewage and sludge are formed, polluting mine passages and affecting normal mine operations, and more work is required for sewage discharge and sludge cleaning, and even the accumulated sewage and sludge have potential safety hazards. [0003] The application provides a mine dust suppression mechanism, which first c...
