Description

Gas spray orifice comprehensive regulation safety device

Technical field

The utility model relates in the coal mine down-hole drilling work progress, and supporting is carried out in the boring of drilling, and reaches the device to the methane gas pump drainage dedusting comprehensive regulation to prevent the methane gas spray orifice.

Background technology

Stone door punching coal, visit the construction of coal hole and coal seam and drill in the process of construction pump drainage hole, how to prevent that the ejection casualty accident is the technical bottleneck that the restriction mine gas is administered in gas accident and boring coal dust, rock dirt, the gas boring always.As not obtaining dealing carefully with the safety that can have a strong impact in the construction of drilling.Present domestic and international drilling at the coal seam prevented certain methods and the device that the spray orifice problem is adopted, and mostly has defective in various degree, and be poor as dust removing effects, the coal dust particle occurs and be inhaled into formation obstruction in the pump drainage pipeline; To shut down deslagging in the process of drilling, have a strong impact on operating efficiency, occur bit freezing easily, embrace to bore, drilling rod fractures the situation of hurting sb.'s feelings; Adopt cement mortar and foaming polyamine fat material to fix to the sealing of hole sleeve pipe, cause the operation sequence complexity, cost increases, and workload is big, can not recycling etc. problem, also wasted a large amount of iron and steel resources simultaneously.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology deficiency; a kind of gas spray orifice comprehensive regulation safety device is provided; to realize comprising the resultant effect of boring protection and dedusting; particularly when a large amount of gas and dust spray orifice are arranged, can play effective protective effect, promote safe construction.

The utility model technical solution problem adopts following technical scheme.

The design feature of the utility model gas spray orifice comprehensive regulation safety device is to be made of drill system, water deduster and cyclone separator of hydraulic prop, wherein:

The drill lower end of system of described hydraulic prop is a hydraulic support, connects Sealed casing pipe, three-way pipe and guard aperture pipe on described hydraulic support successively, and the drilling rod in the operation is positioned at the top;

Be communicated with by the mixing chamber that is in the right side in wired hose and the water deduster with described three-way pipe, mixing chamber is upper hose with the water inlet pipe, and compounding substances imports in dirt pocket; Top at described dirt pocket is provided with the isocon that is communicated with described water inlet pipe; In the bottom of described dirt pocket the water seal scum pipe is set, solidliquid mixture is a passing away with the water seal scum pipe; Air-water mixture is that passage imports cyclone separator with the tube connector;

In described cyclone separator, methane gas is discharged via the gas exhaust pipe, and liquid takes back to the dirt pocket bottom through the deslagging flexible pipe.

The utility model is to adopt the protection of holing of hydraulic prop device, and with water deduster and cyclone separator enforcement mechanical and hydraulic combined dust, compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model is to adopt hydraulic prop fixed sealing borehole jack pipe to substitute original permanent sealing of hole sleeve pipe of fixing with cement mortar and foaming polyamine fat material, this device can make the sealing of hole sleeve pipe be recycled, the time of being wasted when saving sealing of hole, the use of having saved large quantities of steel pipes simultaneously.

2, the utility model adopts independent sealed sleeve pipe, guarantees the sealing to boring, the danger that may cause when effectively having prevented the gas spray orifice.

3, the utility model is provided with mixing chamber before dirt pocket, further strengthens the water dust collection capacity, effectively reduces the dustiness of acting surface, reaches coal dust and is no more than 10mg/m ³Rock dirt is no more than 2mg/m ³Scope of operation gas density is no more than 1%; The dust quantity that goes out in the dust arrester reaches 95%.

4, the supporting cyclone separator that is provided with behind the utility model dirt pocket; residual a small amount of liquid state and dust can be removed through the effect of cyclone separator in the methane gas after dirt pocket is handled; further improve the dust collection capacity of device, protected main gas exhaust pipeline simultaneously.

5, the utility model has been realized the sedimentation that dust and coal are cut by the water seal scum pipe, discharges voluntarily, avoids occurring shutting down in the process of drilling the phenomenon of deslagging, has improved operating efficiency.

6, the utility model is reaching under the prerequisite of predetermined function, reduces own vol as much as possible and is convenient for carrying and shifts, and helps the use in the underground work.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 hydraulic support, 2 Sealed casing pipes, 3 three-way pipes, 4 guard aperture pipes, 5 drilling rods, 6 wired hoses, 7 mixing chambers, 8 dirt pockets, 9 water inlet pipes, 10 isocons, 11 gas exhaust pipes, 12 cyclone separators, 13 deslagging flexible pipes, 14 pressure gauges, 15 water seal scum pipes.

Below pass through the specific embodiment, in conjunction with the accompanying drawings, the specific embodiment that the utility model is described in further detail.

The specific embodiment

Referring to Fig. 1, present embodiment is by the hydraulic prop system of drilling, and three parts of water deduster and cyclone separator are formed.

Shown in Figure 1, hydraulic prop is drilled in the system, is hydraulic support 1 in the lower end, and hydraulic support top is close to Sealed casing pipe 2, three-way pipe 3 and guard aperture pipe 4 successively, and drilling rod 5 is at its operation at top; This system is connected with water deduster by wired hose 6, what at first insert is the mixing chamber 7 on water deduster right side, water in the mixing chamber comes from water inlet pipe 9, the material that mixes enters dirt pocket 8, isocon 10 water inlets are arranged at dirt pocket top, pressure gauge 14 pressure measurement, water coal dust and methane gas are after fully mixing, and solidliquid mixture is discharged through water seal scum pipe 15; Upper water gas mixture methane gas in tube connector enters cyclone separator 12 is discharged by gas exhaust pipe 11, and small amount of liquid takes back to the bottom of dirt pocket 8 through deslagging flexible pipe 13.

To note in use after the first water flowing will noting observing pressure gauge reading in the rig normal work period,, prevent that gas and Dust Capacity from overflowing too greatly if reading is a canonical will be opened hook and allow the water seal scum pipe set level deslagging in the operation of beginning rig.

Operation as follows in the use of the utility model device:

1, hydraulic prop is installed on the rig, connects airtight sleeve pipe, three-way pipe and guard aperture pipe then, connect each pipeline simultaneously, and it is reliable to guarantee that each connects.

2, intake behind the dirt pocket beginning rig drilling operation by water inlet pipe.

3, guarantee that the water seal scum pipe is in suspension status, the unnecessary water yield will flow out and form the nature water-stop automatically, and at this moment can read dirt pocket air pressure by pressure gauge is negative pressure.

4, the rig duration of work notes observing the pressure gauge data, just the water seal scum pipe is put down natural deslagging if become malleation.

Note following item in the step process:

1, in operating process, should note beginning rig work after the first water flowing.

2, in the rig course of work, to note observing pressure gauge reading, then need set level the water seal scum pipe as showing malleation.
