The specific embodiment
Block clearing assembly connection diagram in the blockage-clearing device that Fig. 1 provides for the utility model embodiment, Fig. 2 is the structural representation of block clearing assembly among Fig. 1, Fig. 3 is the structural representation of slagging-off assembly among Fig. 1.
Referring to Fig. 1-Fig. 3, the utility model embodiment provides a kind of blockage-clearing device, wherein, comprises block clearing assembly 1 and slagging-off assembly 2.Block clearing assembly 1 comprises straight tube 11 and high-voltage tube 12, one end 13 of described high-voltage tube 12 stretches into described straight tube 11 and is positioned at the first end 15 of described straight tube 11, in the practical application, first end 15 is communicated with boring 3, and the other end 14 of described high-voltage tube 12 is used for being communicated with pressure duct 4.Slagging-off assembly 2 comprises tee piece 21, described tee piece 21 has the first port 22, the second port 23 and the 3rd port 24, wherein, described the first port 22 is used for being communicated with extraction pipeline 5, described the second port 23 is communicated with the second end 16 of described straight tube 11, is provided with the control valve (scheming not shown) of opening or closing be used to controlling described the 3rd port 24 on described the 3rd port 24.
Herein, straight tube 11 is specifically as follows the short circuit of double headed roller silk, and the specification of short circuit is 2 cun.High-voltage tube 12 is specially snap joint in 4 minutes, and this snap joint one end 13 places in the straight tube 11, is used for penetrating water under high pressure or high-pressure blast, and with the coal petrography powder of dredging boring 3 interior obstructions, the other end 14 of this snap joint is used for connecting mine pressure duct 4.
Referring to Fig. 1, use above-mentioned blockage-clearing device before, the connected mode of blockage-clearing device is as follows: the first end 15 of straight tube 11 is communicated with extraction borehole 3, the second end 16 of straight tube 11 is communicated with the second port 23 of tee piece 21.Then, the first port 22 of tee piece 21 being communicated with extraction pipeline 5, is negative pressure in the extraction pipeline 5.Subsequently, the other end 14 of high-voltage tube 12 is communicated with pressure duct 4, is connected with high-pressure blast or water under high pressure in the pressure duct 4., should be noted that the high-voltage value in the pressure duct 4 should be greater than the negative pressure value in the extraction pipeline 5 herein, such as, the pressure in the pressure duct 4 is 10
7MPa, the pressure in the extraction pipeline 5 is 10
-6MPa is so that high-pressure blast or water under high pressure can successfully be washed the coal petrography powder that stops up in the boring 3 open.
Use the process of above-mentioned blockage-clearing device as follows: at first, by extraction pipeline 5, so that whole blockage-clearing device all is in negative pressure state.Then, wash the coal petrography powder of boring 3 interior obstructions open by pressure duct 4.
Because after boring 3 was blocked, along with the release of gas, boring had certain pressure in 3.High-pressure blast or high pressure water flushing spud in behind the coal petrography powder that stops up in the hole 3, can close high-pressure blast or water under high pressure, and under the effect of boring 3 internal pressures, the coal petrography powder can be blown in the straight tube 11, under the suction function of extraction pipeline 5, can enter into tee piece 21.The 3rd port 24 of tee piece 21 is used for deslagging, after blockage-clearing device uses a period of time, such as a week, disconnects blockage-clearing device and being connected that extraction pipeline 5 is connected with pressure duct, and opens the control valve on the 3rd port 24, gets rid of the coal petrography powder in the tee piece 21.If the coal petrography powder in the tee piece 21 is a lot, can utilize pressure duct 4 to clear up fast.
The blockage-clearing device that technique scheme provides, in the course of the work, blockage-clearing device respectively with boring, pressure duct and extraction pipeline connection, so a whole set of blockage-clearing device is in full closeding state, make the water, coal dust and the gas that spray during the block clearing all enter the slagging-off assembly that is under the negative pressure extraction state, can not cause gas to reveal, so can be used for processing the boring blockage problem, and quick, convenient, safety have been avoided building the pressure in or the hole improper because of boring obstruction manner of cleaning up and have been caused spray orifice to hurt sb.'s feelings and gas accident.
Referring to Fig. 1, for the ease of regulating the pressure state in the tee piece 21, can all be provided with control gate valve (scheming not shown) on described the first port 22 and described the second port 23.Open the control gate valve on the first port 22, tee piece 21 is communicated with extraction pipeline 5, and tee piece 21 also is negative pressure state under the effect of extraction pipeline 5.Open the control gate valve on the second port 23, so that also be negative pressure state in the straight tube 11.
Herein, the pipe at three port places is all selected equal pipe on the tee piece 21, and this sentences and selects diameter is that the pipe of 159mm is example, but is not limited to this.Can respectively weld one 2 cun band silk short circuits on each port, so that tee piece 21 is connected with miscellaneous part.Herein, control valve is selected identical structure with two control gate valves, and size all is 2 cun.
The blockage-clearing device that technique scheme provides, in processing the boring plug-hole, blockage-clearing device is in full closeding state, has avoided causing because of the larger block clearing of boring internal pressure the generation of the casualty accident that boring coal powder injection rock dust causes, and has guaranteed the safety of blocking cleaning work; In processing the boring plug-hole, blockage-clearing device links to each other with mine extraction system, is in negative pressure state in the slagging-off assembly, has avoided that internal pressure is large, gas density is high, spray orifice causes the gas exceeding limit accident because holing.In addition, above-mentioned blockage-clearing device is simple in structure, and input cost is low, original paper is small and exquisite, is easy to carry and operates.
