Abstract
The utility model discloses a mine gas pumping and discharging hole packer which comprises a pumping and discharging pipe, wherein a flexible pipe plug is arranged at the rear end of the pumping and discharging pipe, a valve switch is arranged on the pumping and discharging pipe in front of the flexible pipe plug, a conical elastic plug is backwards fixed on the pumping and discharging pipe in front of the valve switch by an iron sheath, a lengthened pumping and discharging pipe is connected in front of the elastic plug by a pipe joint, a bellows made of elastic material is installed at the front end of the lengthened pumping and discharging pipe by an iron protection joint, and the front end of the bellows is connected with a filter mesh pipe by the iron protection joint. The utility model is applicable to sealing deep hole the phi of which is between 40 to 120 mm and is 6 to 10 m deep, thereby eliminating the trouble of using hole packers of various specifications, and simultaneously having the advantages of convenient use, high efficient, low cost and good adaptability to the environment.
Description
Technical field:
The utility model relates to the mine gas discharging, and particularly a kind of telescopic resilience is good, can be with the irregular variation in gas aperture, and sealing of hole is tight, is suitable for big, the easy to operate mine gas pump drainage hole packer of bore diameter scope.
Background technology:
Traditional drawing out methane is that a releasing pipe is inserted in the gas extraction hole, then cement paste or polyurethane advanced to carry out shutoff, pump drainage in the hole with shutoff equipment pressure injection.This method is not only time-consuming, effort but also cost height, efficient are low; Hydraulic type or vapour-pressure type gas hole packer, use inconvenient, also easy spalling water, air pipe, sealing of hole weak effect at the manufacturing cost height; I the patent No. of first to file be 200820149078X " gas in mine rapid hole sealing device " it be to protect head near welding one on the filter mesh section on the pump drainage pipe, protect head and go up and around the outer wall of pump drainage pipe back, be fixed with a cone resilient plug.Though the advantage that this structure has is simple in structure, cost is low, swift to operate is found that in practice it only is adapted at using in the shallow bore hole in nearly coal seam, as is run into degree of depth sealing of hole when the situation of 6-10 rice, then can not reach the effect of design.
Summary of the invention:
The purpose of this utility model provides a kind of mine gas pump drainage hole packer of degree of depth sealing of hole.
The technical solution of the utility model is finished as follows, it includes a pump drainage pipe, be provided with hose plug in pump drainage pipe rear end, pump drainage pipe before the hose plug is provided with a valve switch, pump drainage Guan Shangyong iron sheath before the valve switch is fixed with a cone resilient plug backward, it is characterized in that: before resilient plug, be connected with a lengthening pump drainage pipe with union, protect head at lengthening pump drainage pipe front end with iron one bellows of being made by elastomeric material is installed, the front end of bellows protects head with iron and is connected with a filter mesh pipe.The material of bellows can be silica gel, rubber, rubber and plastic or thermoplastic elastomer.The utility model is applicable to the deep hole sealing of hole to φ 40～120mm and 6-10 rice, saved the trouble that the plurality of specifications hole packer is used in the down-hole, and have easy to use, efficient is high, cost is low, the advantage strong to environmental suitability.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is improvements over the prior art, it is that a hose plug 11 is set in the rear end of a pump drainage pipe 9, pump drainage Guan Shangyong iron before hose plug protects 7 and is fixed with a cone resilient plug 8 backward, its improvements are to be connected with a lengthening pump drainage pipe 5 with union 6 before resilient plug, protect 4 and 2 at lengthening pump drainage pipe front end with two iron the bellows 3 that an elastomeric material is made is installed, the front end iron of bellows protects on 2 and is connected with a filter mesh pipe 1.The material of bellows selects for use silica gel, rubber, rubber and plastic or thermoplastic elastomer to make, and not only telescopicing performance is good, and good springiness, can change with the irregular variation of boring aperture, and sealing of hole is tight, air tight.During use, pick up hole packer and aim at the gas stopple and enter get final product, very easy to use quick, in a few minutes, can finish degree of depth sealing of hole, to mine increase output and efficient, be not afraid of humidity, wear-resisting wiping, antistatic, fire-retardant, environmental suitability is strong.
