It is preferred embodiment provided by the utility model shown in referring to Figures 1 and 2.

The scarfing cinder processing structure of gas lift reverse circulation provided by the embodiment of the utility model, in time will be in groove body 15 by gaslift The rubble in portion is removed, so that milling wheel 12 continues to rotate down cutting, breaking hard rock, hard rock grooving hinders few thus more efficient.

The scarfing cinder processing structure of gas lift reverse circulation provided in this embodiment, two inside the groove body 15 including going deep into rock stratum Counter-rotational milling wheel 12 and the guide post 11 for supporting milling wheel 12, guide post 11 are located at 12 top of milling wheel and are arranged vertically, In guide post 11 there is one end to be connected to the mud tube 131 outside groove body 15 and the tracheae towards 131 exhaust gas inside of mud tube； There is deslagging gap 121 between two milling wheels 12, and be located at the two sides in deslagging gap 121, two milling wheels 12 rotate from bottom to top, The other end of mud tube 131 is placed in the surface in deslagging gap 121.

In this way, exhaust pipe 141 is to injecting gas inside mud tube 131, gas is by the anti-row of act of residue in mud tube 131 Out, two milling wheels 12, which are rotated backward, carries out cutting and crushing to hard rock, and broken residue turns in deslagging gap 121, and passes through The drive of milling wheel 12 is rotated up, and residue is then sucked mud tube through 15 inside of groove body and the internal and external pressure difference of mud tube 131 In 131, residue in mud tube 131 gas instead lift discharge groove body 15 outside, i.e., carried out while 12 cutting and crushing of milling wheel Residue discharge, is cleared up inside groove body 15 in time, guarantees the efficient operation of milling wheel 12, and the efficiency of hard rock grooving is also higher.

In addition, one end of mud tube 131 is connected to the mud separator 13 for separating mud with sandstone, pass through mud Separator 13 separates mud and sandstone, in order to recycle respectively.

Specifically, settable waffle slab in mud separator 13, coarseer particle stay on waffle slab, mud is then flowed into The bottom of mud separator 13, so that the separation of mud and sandstone can be realized.

Also, mud separator 13 is extended with the drain pipe 132 of discharge sandstone respectively and the sludge pipe of mud is discharged 133, specifically, drain pipe 132 is arranged on 13 top of mud separator, the bottom of mud separator 13 is then arranged in sludge pipe 133 Portion, so that recycling is discharged in sandstone and mud respectively.

The top of sandstone containing box 134 is arranged in far from one end of mud separator 13 for above-mentioned drain pipe 132, in order to receive Collect sandstone.

In addition, sludge pipe 133 extends to the surface of groove body 15 far from one end of mud separator 13, specifically, spoil disposal One end of official extends to the forward direction side of groove body 15, and to bending downward inside groove body 15, that is, passes through sorted premium mud meeting It is drained into inside groove body 15 again, to keep the stabilization of 15 side wall of groove body, effectively reduces the waste of mud, save construction cost, In addition, good mud also facilitates subsequent grooving injection concrete setting.

In addition, guide post 11 has the cavity 111 of downwardly facing opening, one end of mud tube 131 is extended in cavity 111, is arranged One end of tracheae 141 extends in mud tube 131, in such manner, it is possible to guarantee that there are pressure in 15 inside of groove body and mud tube 131 Difference, in order to which residue is discharged along mud tube 131.

Also, mud tube 131 is arranged in the center of cavity 111, and guide post 11 is kept to arrange vertically, to guarantee to be in The verticality of groove body 15.

Meanwhile the side wall of the attaching cavity 111 of exhaust pipe 141 extends to inside mud tube 131, keeps consolidating for exhaust pipe 141 It is fixed, in order to stabilize exhaust.

In the present embodiment, the quantity of exhaust pipe 141 is two, and is arranged in the two sides of cavity 111, guarantees guide post 11 two lateral balances so that two milling wheels 12 can cutting and crushing straight down, guarantee the verticality of groove body 15.

Likewise, the two sides of guide post 11 are fixedly installed davit 112 respectively, the davit 112 of two sides is arranged symmetrically, and point It is not attached to the side wall of 15 two sides of groove body, to guarantee that milling wheel 12 is transferred vertically, guarantees the verticality of groove body 15.

112 top of davit of above-mentioned two sides is fixedly connected with lifting rope, hangs the davit for setting two sides respectively by the lifting rope of two sides 112, keep the vertical decentralization of guide post 11.

Also, lifting rope of two exhaust pipes 141 along two sides extends in mud tube 131, to guarantee two exhaust pipes 141 Stablize arrangement.

In addition, two exhaust pipes 141 attach the side wall of cavity 111 towards extending respectively, mud tube 131 is then extended to Inner sidewall, and the inner sidewall for attaching mud tube 131 extends downward, so as in the gas being discharged into mud tube 131, from middle part Direction is discharged, the anti-residue lifted in mud tube 131 upwards, and then be discharged, guarantees the steady operation of milling wheel 12.

In this way, the other end of exhaust pipe 141 is connected to the expansion box for containing gas, by the gas that is stored in expansion box to Exhaust in mud tube 131.

Also, expansion box is connected to air compressor machine 142, and the gas in expansion box is pressed into exhaust pipe by air compressor machine 142 141, and then be discharged into inside mud tube 131.

It is 141,2 cubes of exhaust pipe of the air accumulator 14 of the mud tube 131 of Φ 300mm, 50mm given by the present embodiment And the air compressor machine 142 of 150KW, to keep efficient 15 inside scarfing cinder of groove body to handle, certainly, concrete model and caliber can be with Depending on according to actual needs, however it is not limited to above-mentioned data.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
