Abstract

The utility model discloses an air and water separating stabilizer for a mining drill. The air and water mixture entering the stabilizer is caused to be separated via the high-speed rotation of a spiral blade-typed gas-water separator; the separated water flows downward to the male thread-typed injection nozzle to be ejected along the inner wall of the stabilizer and a void between the inner wall of the stabilizer and a damping plate, but does not pass through a drill; the unhydrous gas flows to the drill through an iron pipe, therefore, the goal of removing dust in the wet way and keeping the drill drilling in dry type is achieved, and the service life of the drill is extended.

Description

Mining-drilling machine gas-water separation formula stabilizer

The utility model relates to a kind of rig stabilizer, a kind of mining-drilling machine gas-water separation formula stabilizer of more specifically saying so.

The mining rotary drill that uses during at present the mine produces comprises the rig that western countries' designs such as the U.S., Canada, Sweden are produced, and all adopts wet dust removal at the bottom of the air-water mixture hole, because moisture airflow passes drill bit causes the wearing and tearing of drill bit burn into violent unusually.

The purpose of this utility model is that the mining rotary drill for wet dust removal at the bottom of the air water mix aperture provides a kind of gas-water separation formula stabilizer, be implemented in the gas-water separation in the stabilizer, make water not by drill bit and bearing, but above drill bit, spray, drill bit remains on dry type and creeps into work under the state, can wet dust removal thereby reach, can prolong the effect of drilling life of bit more than one times again.

For achieving the above object, the utility model has adopted a kind of stabilizer with the blade gas separator, it is installed on the mining rotary drill of common wet dust removal, when the air intake vent of moisture gas by the stabilizer top enters, when flowing through the blade gas separator, since eliminator together with whole stabilizer all along with drill bit do to quicken centrifugal rotatablely moving, the impeller hemisphere physical efficiency on blade gas separator top reduces air resistance, spiral angle is the eliminator body generation acceleration of 30 ° helical blade simultaneously, air-water mixture is rotated at a high speed, thereby make gas, water reaches sufficient separation.

Because along the inwall of stabilizer, the male thread formula mouth place that the gap by damping sheet and stabilizer inwall flow to above the drill bit outwards sprays, and is used for dedusting under the isolated current direction of gas separating device; Water-free gas is then entered through iron pipe by iron pipe top and arrives drill bit.

The utility model has the advantages that: (1) is simple in structure, and operation installation and replacing rig stabilizer are very easy; (2) shunting of employing air water can make rig creep under dry state and can reach the wet dust removal effect, therefore on the basis that keeps original dust removing effects, the corrosive wear degree of drill bit is reduced greatly, at least prolong drilling life of bit more than one times, can greatly reduce the mine cost of production; (3) this stabilizer does not change mining-drilling machine structure and operation sequence, and small investment, cost are low, can bring bigger economic benefit for bargh.

As seen from Figure 1, the upper end of gas-water separation formula stabilizer body 2 is linked to each other with drilling rod by male thread 1, the outer wall of stabilizer body 2 is with the alloy wear-resisting band 3 of band breast nail, and its inside is installed helical blade type moisture trap 4 from top to bottom successively, damping sheet 5, is fixed on the iron pipe 6 in the damping sheet 5.Moisture trap 4, damping sheet 5 and iron pipe 6 wherein can be fixedlyed connected as a whole with the inwall of stabilizer body 2 in several ways.In the present embodiment, moisture trap 4 is directly to be stuck on the inwall of stabilizer body 2, iron pipe 6 is welded in the circular hole of damping sheet 5, four of damping sheet 5 connect pawls 10 also is that 7 at male thread bolt type nozzle directly is screwed on the thread filament hole of stabilizer both sides on being welded on the inwall of stabilizer body 2.When rig is worked, stabilizer body 2 is rotation at a high speed thereupon, moisture gas passes through helical blade type moisture trap 4 after air intake 11 enters stabilizer body 2, along with helical blade 9 is done the centrifugation accelerates motion, thereby generation gas-water separation, isolated water continues along the space between stabilizer inwall and the damping sheet 5 to dirty, outwards spray until male thread bolt type nozzle 7, be used for dedusting, isolated dry gas then moves downward through drill bit by iron pipe 6, and stabilizer body 2 lower ends are connected with drill bit by box thread 8.

Male thread 1 and box thread 8, its screw thread is complementary with drilling rod and drill bit respectively, wear-resistingly then is complementary with the external diameter of drill bit with 3 size.The diameter dimension of assemblies such as helical blade type moisture trap 4, iron pipe 6 and damping sheet 5 is also respectively along with the size of stabilizer changes and changes.

The effect of Fig. 4, damping sheet 5 shown in Figure 5 is to stop isolated water to enter the mouth with returning on gas mixes to iron pipe again, its inside and outside footpath size is complementary with the internal diameter of stabilizer, the outside dimension of iron pipe respectively, iron pipe 6 cards are welded in the interior ring of damping sheet 5, between the upper end of iron pipe 6 and the helical blade type moisture trap 4 at a distance of about 15mm, four on damping sheet 5 outer shrouds connect pawl 10 and directly are welded on the stabilizer inwall, with the fixing position of damping sheet 5, its length * wide * thick: 20 * 10 * 5mm, damping sheet 5 inclined-plane angles are 25 ° and 75 °.

Fig. 6 and male thread bolt type nozzle 7 shown in Figure 7 are passages of the current that are separated, it is made up of different sparge pipe and the hollow bolts of hole for water spraying, internal diameter that is attached on stabilizer body 2 inwalls, bolt can also can be an outer-hexagonal formula bolt with interior hexagonal formula, when taking place to stop up, hole for water spraying is easy to dismounting, the convenient repairing.

Fig. 2, the hollow hemisphere that helical blade type moisture trap 4 shown in Figure 3 is made up of helical blade 9, the two ends external diameter of helical blade 9 is ascending, lead angle is from 20 °-65 °, the thick 2mm of blade, tapering is  55- 65 degree,  395- 405, the gas communication space from large to small, gas flow has an accelerator, a number of helical blade 9, hemispheroidal inner and outer diameter all will change along with the internal diameter size of stabilizer body 2 and change, so that helical blade moisture trap 4 is snapped in the stabilizer body 2 on demand, helical blade 9 is 8 and 24 among the embodiment.The visible aperture of spiral blade separator 4 plugs one end is the centre bore in the machining process, but also not exclusively beats, and is convenient to process support.
