CN201606101U - Ventilation and dust prevention integrated device for mining - Google Patents

Abstract

The utility model discloses a ventilation and dust prevention integrated device for mining, which belongs to the technical field of mine drilling machinery auxiliary equipment. Mine drilling, particularly coal mine deep-hole drilling, has the problems of large slagging volume and more severe dust, slagging can only rely on air pressure in case of adopting non-screw drilling poles, and even if screw drilling poles are adopted, gas should also be decompressed and exhausted via ventilation. The technical scheme of the integrated device includes that a rotary shaft (5) is mounted in an inner bushing (12), a ventilation hole (7) and an air inlet hole (6) are respectively disposed in the rotary shaft (5), a middle bushing (15) provided with a water inlet hole (18) and a first air hole (22) is fixedly sleeved outside of the inner bushing (12), an outer bushing leather (13) provided with a sealing ring (2) and a bearing (3), and a second outer bushing leather (19) are sleeved outside of the middle bushing (15), and a water curtain sprayer (8) provided with a spout hole (11) is screwed on a water curtain sprayer body (16). The ventilation and dust prevention integrated device for mining has the advantages of capability of achieving the integral effect of ventilation and dust prevention in synchronous drilling operation without mutual affection.

Description

The mining ventilation dirt integrated apparatus that goes out

Technical field: the utility model relates to the mine and creeps into mechanical corollary apparatus technical field, is the mining ventilation dirt integrated apparatus that goes out more specifically.

Background technology: the mine especially coal mine deep hole to creep into the big dust of bed drain purge even more serious, adopt no auger stem can only lean on the blast deslagging, even if adopt the auger stem deslagging also must the ventilation and pressure release firedamp drainage, the function of the dirt of how realizing can ventilating and can go out? so it is necessary designing a kind of ventilation supporting rig operation of dirt integrated apparatus of going out.

Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is the mining ventilation of the design dirt integrated apparatus that goes out.Its technical scheme is: in the interior cover skin rotating shaft is housed, have gravity vent and fresh air inlet in the rotating shaft, interior cover skin external fixation is with the middle cover skin of bringing the water hole and the first wind hole into, outside middle cover skin, be with the overcoat skin and the second overcoat skin of band joint ring and bearing, the drencher head that has hole for water spraying is screwed on the drencher head body, water inlet tap and overcoat skin are fixedly connected, form water jacket between overcoat skin and the middle cover skin, water inlet tap, water jacket, the inlet opening, interbed, sump is connected successively with hole for water spraying and communicates, on interior cover skin, have the second wind hole, the tuyere and the second overcoat skin are fixedly connected, tuyere, the wind storehouse, the first wind hole, the second wind hole, fresh air inlet is connected successively with gravity vent and communicates, during catch is screwed in by screw thread on the cover skin.The advantage of this utility model is: reasonable in design, and the novelty that is skillfully constructed, but synchronous working is independent of each other so that reach the incorporate effect of dirt of going out of ventilating when bore operation, has good economic results in society.

Description of drawings: accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, water inlet tap, 2, joint ring, 3, bearing, 4, catch, 5, rotating shaft, 6, fresh air inlet, 7, gravity vent, 8, drencher head, 9, interbed, 10, sump, 11, hole for water spraying, 12, interior cover skin, 13, overcoat skin, 14, the second wind hole, 15, middle cover skin, 16, the drencher head body, 17, water jacket, 18, the inlet opening, 19, the second overcoat skin, 20, tuyere, 21, Feng Cang, 22, the first wind hole, 23, the rig joint, 24, tool joint.

The specific embodiment: in the interior cover skin 12 rotating shaft 5 is housed, have gravity vent 7 and fresh air inlet 6 in the rotating shaft 5, interior cover skin 12 external fixation are with the middle cover skin 15 of bringing the water hole 18 and the first wind hole 22 into, outside middle cover skin 15, be with the overcoat skin 13 and the second overcoat skin 19 of band joint ring 2 and bearing 3, the drencher head 8 that has hole for water spraying 11 is screwed on the drencher head body 16, water inlet tap 1 is fixedly connected with overcoat skin 13, form water jacket 17 between overcoat skin 13 and the middle cover skin 15, water inlet tap 1, water jacket 17, inlet opening 18, interbed 9, sump 10 is connected successively with hole for water spraying 11 and communicates, on interior cover skin 12, have the second wind hole 14, the tuyere 20 and the second overcoat skin 19 are fixedly connected, tuyere 20, wind storehouse 21, the first wind hole 22, the second wind hole 14, fresh air inlet 6 is connected successively with gravity vent 7 and communicates, during catch 4 is screwed in by screw thread on the cover skin 15.Rig joint 23 inserts in the rig and installs, drill bit is installed in tool joint 24, starting rig like this rotates 8 of drencher heads and rotating shaft 5 synchronously, water inlet tap 1 is connected the water source just penetrates annular arrangement from hole for water spraying 11 by water jacket 17, inlet opening 18, interbed 9 and sump 10 waterline, because of rotating these waterlines has just formed rotary water curtain at a high speed, because of hole for water spraying has constant slope, so water curtain becomes umbrella to reach the go out effect of dirt of sealing of hole.Tuyere 20 is connected wind regime and is just passed through wind storehouse 21, the first wind hole 22 and the second wind hole 14 through fresh air inlet 6 through rotating shaft centers, gravity vent 7 directly blows at the bottom of the hole by drilling rod hollow, the wind-force backspace deslagging that is obstructed has improved rate of penetration rapidly, in rotating shaft 5, realize synchronous rotary work like this, so formed the dirt integrated apparatus that goes out that ventilates with drencher head 8.Can supporting rig extensive use realize not only improving penetration rate but also not having dust work.
