Abstract
The utility model discloses a wind-pressing-type fast hole sealing device for an underground coal mine. The wind-pressing-type fast hole sealing device for the underground coal mine is characterized in that a material inlet is formed in the top of a tank body, a sealing cover is assembled on the material inlet, a material outlet is formed in the bottom of the tank body, and a spherical valve is arranged on the material outlet. An air intake and an air outlet are formed in the tank body, and an air inlet valve and an air outlet valve are assembled on the tank body. A safety valve is arranged at the position of the air intake. Stirring vanes are arranged in the tank body, and the stirring vanes are driven by an air motor which is arranged at the upper portion of the tank body. When the wind-pressing-type fast hole sealing device is used, the material outlet aims at a sealing hole, and under the action of pressure in the tank body, sealing hole materials are poured into the sealing hole to seal the hole. By the adoption of a sealing hole method of the novel sealing device, the depth of the sealing hole sealed by the sealing device can be reached more than 20m, the sealing device matched with the high-dense sealing hole materials is not contractive at all in a drill hole, is suitable for sealing holes of any gas drainage drill holes and blast holes and has the advantages of being reliable in performance, convenient to use and the like. When the wind-pressing-type fast hole sealing device for the underground coal mine is popularized completely, a great economic benefit can be produced for amount of sealing hole cost of coal mines, and a great safety benefit can be produced for production safety of the coal mines due to the fact that the quality of the sealing hole is improved.
Description
Technical field
When the utility model relates to a kind of coal mining explosion and extraction, in, the sealing of hole special equipment of deep hole.
Background technology
In the last few years, complexity day by day along with the China's coal-mine mining environment, each colliery is also more and more paid attention to gas preventing and control, wherein, extraction in advance to coal-bed gas is an important means that prevents gas, and the effect of pre-extraction is better, and extraction is than higher, environment when exploitation is better, and the possibility that has an accident is also just lower.In the links of gas drainage under suction, the shutoff of holing for extraction is again one of them key point link.Therefore, country has carried out mandatory provision to the shutoff of extraction boring in the new colliery technical security standard of in August, 2009 regulation, and the shutoff distance reaches 8 meters at least.
At present.Tradition is carried out shutoff with polyurethane, the length of shutoff only has 1 meter left and right, at the polyurethane sealing of hole, manually send cementing and calm the anger send cementing hole sealing depth generally all less than 5m, be applicable to short time firedamp taking-out discharging drilling sealing of hole and the short firedamp taking-out discharging drilling sealing of hole of tunnel rib zone of fracture; There is the phenomenon of gas leakage to cause extracting result bad, seriously polluted to production environment, also there is no supporting special-purpose plugging equipment at the deep hole blasting sealing of hole, the safety in production of mine is caused very large threat.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the utility model provides rapid hole sealing equipment a kind of simple to operate, safe.
The purpose of this utility model is achieved through the following technical solutions: be used for coal mine and press down wind formula rapid hole sealing equipment, it is characterized in that: at tank body top installation charging aperture, charging aperture is equipped with seal cover, tank base is provided with discharging opening, and discharging opening is provided with globe valve, is provided with air intake on tank body, mouth leaks informaton, and equipped air inlet valve and vent valve, at air intake place mounting safety valve, paddle is installed in tank body, and is driven by the pneumatic motor of tank body top.
The beneficial effects of the utility model: the utility model adopts said structure, during use, discharging opening is aimed at sealing of hole, under the effect of tank body internal pressure, seals after sealing material is injected sealing of hole.Adopt Novel sealing equipment method for sealing, more than the hole sealing depth of plugging equipment sealing of hole can reach 20m, coordinate the high-consistency sealing material of selecting substantially not shrink in boring, be applicable to the sealing of hole of all kinds of firedamp taking-out discharging drillings and shot hole, no matter improve from the artificial effect of sealing of hole and still save the aspect consideration of sealing of hole funds, this hole sealing device has unrivaled advantage, has dependable performance, the advantage such as convenient and practical.All-round popularization will bring great economic benefit to a large amount of sealing of hole expenses in colliery, and sealing quality improves also will bring huge safety benefit to the colliery production safety.
