Abstract
The utility model discloses a dust reducing device, in particular to a dust reducing device for gas drainage hole in a coal mine. A drilling rod (9) is movably arranged inside a drilling rod ventilating pipe (1), a connecting pipe (2) is connected at the middle lower part of the drilling rod ventilating pipe (1), a fixing plate (10) is connected at the lower end of the connecting pipe (2), the upper part of a dust reducing box body (3) is fixed on the fixing plate (10) through a bolt (8), a baffle plate (12) is respectively arranged at the inner lower bottom part of the dust reducing box body (3) and at the inner upper part of a lower dust discharge opening (4) at a certain inclination angle, and a water-spraying dust reducing mechanism is arranged at the inner middle part of the dust reducing box body (3). Since the spraying device is sealed by adopting the box body, the dust reducing device is installed on the machine body of a gas drainage hole drilling machine, the gas drainage hole drilling machine is fully covered by the drilling rod ventilating pipe above, the purpose of effective dust reduction can be achieved by using the water-spraying dust reducing mechanism, and the coal dust can be prevented from flying; the dust reducing device has the advantages of simple structure, convenient assembly and disassembly, and scientific and reasonable design; and the dust-removal efficiency can be up to 95 percent, thereby avoiding the environmental pollution.
Description
Technical field: the utility model relates to a kind of device for reducing dust, specifically is gas discharge in mine boring device for reducing dust.
Background technology: at present, in colliery comprehensive mechanization firedamp taking-out discharging drilling, the coal dust amount is bigger, and the serious harm underground labour is healthy, and has coal dust explosion hazard.So seek dust prevention targetedly is firedamp taking-out discharging drilling technology urgent problem.Coal dust source mainly is firedamp taking-out discharging drilling, coal-winning machine coal cutting, move to put in coal, the work plane transportation reprinting process behind frame, the frame and produce.Coal dust still is one of subject matter of puzzlement Coal Production, and the dust of high concentration especially respirable dust is the immediate cause of bringing out workman's tuberculosis.For depositing dust, people have designed multiple dust falling device, existing China's coal-mine firedamp taking-out discharging drilling dust-settling technology is mostly based on interior external spraying, because the design of the outer spray of high pressure system is huge, injection field and high-pressure nozzle design are unreasonable, and nozzle is easily stifled, water consumption is big, atomizing effect and dust-laying effect are not good, and spraying system is reason such as operate as normal for a long time, and dust-laying effect is very undesirable.
The utility model content: purpose of design of the present utility model is to overcome the weak point in the prior art, when being provided, a kind of atomizing de-dusting supplies with water under high pressure, and atomizing de-dusting is effective, the gas discharge in mine of dust concentration boring device for reducing dust in the time of can reducing firedamp taking-out discharging drilling greatly.
The technical scheme that the utility model technical solution problem is adopted is: described drilling rod 9 is movably placed in the ventilative pipe of drilling rod 1 inside, and be connected with the rubber seal 11 that is embedded in the ventilative pipe of drilling rod 1 right the inner, tube connector 2 is connected 1 time middle part of the ventilative pipe of drilling rod, its lower end is connected and fixed plate 10, depositing dust casing 3 tops are fixed on the fixed head 10 with bolt 8, following dust-exhausting port 4 is arranged on 3 times middle parts of depositing dust casing, baffle plate 12 inclination certain angle devices lower bottom part in depositing dust casing 3 reaches the internal upper part of dust-exhausting port 4 down, and mechanism of water spray dust is arranged on middle part in the depositing dust casing 3.
The beneficial effects of the utility model are: owing to adopt box sealing space depositing dust, be installed on the firedamp taking-out discharging drilling rig fuselage, the ventilative pipe of top drilling rod covers the firedamp taking-out discharging drilling rig fully, utilize the effective depositing dust of mechanism of water spray dust, can stop dust from flying, also can be effectively the coal dust that sprays in the coal hole be concentrated and reclaim, and the secondary fly-up when having avoided the cleaning coal dust, dust is eliminated produced the dirt place.And simple in structure, easy to loading and unloading, dust removal efficiency can reach more than 95%, has avoided environment pollution.
Description of drawings: Fig. 1 is a main sectional view of the present utility model.
Fig. 2 is the vertical view of Fig. 1
The specific embodiment: as shown in Figure 1 and Figure 2: described drilling rod 9 is movably placed in the ventilative pipe of drilling rod 1 inside, and be connected with the rubber seal 11 that is embedded in the ventilative pipe of drilling rod 1 right the inner, tube connector 2 is connected 1 time middle part of the ventilative pipe of drilling rod, its lower end is connected and fixed plate 10, depositing dust casing 3 tops are fixed on the fixed head 10 with bolt 8, following dust-exhausting port 4 is arranged on 3 times middle parts of depositing dust casing, baffle plate 12 inclination certain angle devices lower bottom part in depositing dust casing 3 reaches the internal upper part of dust-exhausting port 4 down, and mechanism of water spray dust is arranged on middle part in the depositing dust casing 3.
As shown in Figure 1 and Figure 2: the water-supply-pipe 5 of mechanism of described water spray dust installs at depositing dust casing 3 right-hand members, and is connected with water storage ball 6, and copper nozzle 6 is movably connected on the water storage ball 6.4 copper nozzle 6 equidistant heads are around water storage ball 6, and 1 copper nozzle 6 vertical means is in water storage ball 6 lower ends.
Purpose of design of the present utility model can also reach by following measure: this device has two models, and a device is on large-scale firedamp taking-out discharging drilling rig fuselage; Another can directly be stably fixed on the rib of rhombus net.
Claims (3)
1. gas discharge in mine boring device for reducing dust, it is characterized in that drilling rod (9) is movably placed in the ventilative pipe of drilling rod (1) inside, and be connected with the rubber seal (11) that is embedded in the right the inner of the ventilative pipe of drilling rod (1), tube connector (2) is connected the ventilative pipe of drilling rod (1) middle part down, its lower end is connected and fixed plate (10), depositing dust casing (3) top is fixed on the fixed head (10) with bolt (8), following dust-exhausting port (4) is arranged on middle part under the depositing dust casing (3), baffle plate (12) inclination certain angle device lower bottom part in depositing dust casing (3) reaches the internal upper part of dust-exhausting port (4) down, and mechanism of water spray dust is arranged on middle part in the depositing dust casing (3).
