Description
Technical field
The utility model relates to a kind of hole sealing device, is particularly useful for the capsule hole sealing device that under a kind of coal mine coal bed drilling is used.
Background technology
Along with the standard of China to the mine gas extraction, and the attention of global low-carbon (LC) environmental protection, the work of China's coal-mine gas pumping just seems particularly important.Cooperate at present employed sealing material such as colliery gas pumping, method varied, get up to be divided into slurry type, expanded material type two big classes but sum up.The slurry type material require uses supporting electronic or pneumatic or manpower pumping plant, with the material injection hole that stirs, utilizes solidifying of slurries to seal boring, this method sealing of hole is longer man-hour, and operation is complicated, simultaneously solidifying owing to slurries, the extraction pipeline is not recyclable, and cost is higher.Expanded material is many based on polyurethane, it utilizes the chemical reaction of chemical material, dilatancy seals boring, but this kind series material reaction speed is general all several seconds to tens seconds scope, and the workman has little time operation at all, has reduced the performance that material itself should be brought into play, this material mostly is noxious material simultaneously, the workman's who has a strong impact on health of human body, and this material is not recyclable yet, and the sealing of hole cost is higher.Bring bigger economic pressures to enterprise's production.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, easy to use, environment friendly and pollution-free, two capsule capsule hole sealing devices that can reuse.
For achieving the above object, capsule hole sealing device of the present utility model comprises the gas pumping pipe, the front portion of gas pumping pipe is provided with air inlet pipe, gas pumping pipe spacer sleeve is equipped with two recyclable expanded rubber capsules, the two ends of two recyclable expanded rubber capsules all are provided with and make it be fastened on pressed joint on the gas pumping pipe, the pressed joint place is equipped with the pipe joint that connects source of the gas, be connected with the gas tube that links to each other with inflator pump on each pipe joint respectively, the rear portion of gas pumping pipe is provided with the stream pressure table that detects its air-flow, and be provided with orifice flowmeter, gas pumping pipe afterbody is provided with control valve, is equipped with the flow pressure table of its flow of control on described each gas tube.
Have a plurality of air inlets on the tube wall of described air inlet pipe; Described flow pressure table is fixed on the gas pumping pipe side by side by bearing.
Beneficial effect: use two recyclable expanded rubber capsule inflation carrying out sealing of holes, only need an inflator or manual pump can finish sealing of hole, solved existing hole-sealing technology complicated problems, and do not use the chemical synthesis slurries to fill, nontoxic pollution-free, simple in structure, easy to use, can reclaim repeatedly and utilize, have significant practicality.
Description of drawings
Accompanying drawing is a capsule hole sealing device structural front view of the present utility model,
Among the figure: 1-air inlet pipe, 2-pressed joint, the recyclable expanded rubber capsule of 3-, 4-gas pumping pipe, 5-gas tube, 6-pipe joint, 7-stream pressure table, 8-flow pressure table, 9-orifice flowmeter, 10-control valve.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
As shown in the figure, capsule hole sealing device of the present utility model comprises gas pumping pipe 4, the front portion of gas pumping pipe 4 is provided with the air inlet pipe 1 that has a plurality of air inlets on the tube wall, gas pumping pipe 4 spacer sleeves are equipped with two recyclable expanded rubber capsules 3, the two ends of two recyclable expanded rubber capsules 3 all are provided with and make it be fastened on pressed joint 2 on the gas pumping pipe 4, pressed joint 2 places are equipped with the pipe joint 6 that connects source of the gas, be connected with the gas tube 5 that links to each other with inflator pump on each pipe joint 6 respectively, the rear portion of gas pumping pipe 4 is provided with the stream pressure table 7 that detects its air-flow, and be provided with orifice flowmeter 9, gas pumping pipe 4 afterbodys are provided with control valve 10, be equipped with the flow pressure table 8 of its flow of control on described each gas tube 5, flow pressure table 8 is fixed on the gas pumping pipe 4 side by side by bearing; In two recyclable expanded rubbers 3 on the gas pumping pipe 4, the gas tube 5 that is connected at the pipe joint 6 of the recyclable expanded rubber 3 of front position is from passing in the recyclable expanded rubber 3 of position, back.
The course of work: in the sealing of hole process, the capsule hole sealing device is put into the boring precalculated position, give recyclable expanded rubber capsule 3 inflations with inflator, inner gas pressure power is less than 0.5MPa, recyclable expanded rubber capsule 3 is under the effect at internal gas, can expand according to outside restricted clearance shape, play the effect of sealing boring perisporium, thus sealing boring; When reclaiming, open the gas port of flow pressure table 8, emit the gas in the recyclable expanded rubber capsule 3, recyclable expanded rubber capsule 3 shrinks, and the capsule hole sealing device breaks away from boring, takes out to get final product.
