Abstract
The invention discloses a high pressure shallow hole water injector for the fully mechanized coal mining face. The water injector belongs to the field of mine water injectors. The water injector comprises a main liquid inlet pipe and a hole packer and further comprises a planar stop valve, a water outlet pipe and a flexible pipe. The planar stop valve is connected with the main liquid inlet pipe, the planar stop valve is communicated with the main liquid inlet pipe, one end of the water outlet pipe is connected onto the planar stop valve, and the other end is blocked by a plug. One end of the flexible pipe is connected with the water outlet pipe, and the other end is connected with the hole packer. Compared with the traditional water injection process, the water injector saves time, solves the contradiction between dust treatment and production, well controls the pump station pressure by arranging a plurality of control valves and stop valves on the pipeline, reduces damage to high pressure to the hole packer and prolongs the service life of the hole packer.
Description
Technical field
The present invention relates to injector field, colliery, specifically, the present invention relates to coal mine fully-mechanized mining working high pressure shallow holes irrigation device.
Background technology
Mine dust is the large killer of colliery industry one.Colliery industry, annual newly-increased anthraco-silicosis patient is more than ten thousand people, and dust harzard is big, is more and more paid attention to.Tradition administers dust often to be needed to sacrifice the more production time.At present, under the requirement of output, the time that grass-roots unit spends on treating flour dust is little, and thus mine dust can not be effectively controlled from source.Traditional high pressure water injection, because pump station pressure is high and wayward, often occur that hole packer damages phenomenon, being often only in hole packer, is also a no small input.The fully-mechanized mining working water filling of existing injector to this work plane that be uneven is more difficult and can not disperse water filling.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of injector, and this injector water injection pressure is controlled, and can carry out dispersion water filling to rugged work plane.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: coal mine fully-mechanized mining working high pressure shallow holes irrigation device, comprise main feed tube and hole packer, also comprise Plane stop valve, outlet pipe and flexible pipe, described Plane stop valve is connected with main feed tube, Plane stop valve and main feed tube junction through, one end of described outlet pipe is connected on Plane stop valve, and other end plug is blocked; One end of described flexible pipe is connected with outlet pipe, and the other end is connected with hole packer, and described flexible pipe has one at least.
Preferably, described outlet pipe and Plane stop valve junction are provided with hydralic pressure gauge.
Preferably, described flexible pipe and outlet pipe junction are provided with stop valve.
Adopt the technical scheme of invention, following beneficial effect can be obtained:
Coal mine fully-mechanized mining working high pressure shallow holes irrigation device of the present invention, an outlet pipe arranges multiple flexible pipe arranged side by side, saving water injection time compared with traditional waterflood technique, solves the contradiction between treating flour dust and production; Whole pipeline arranges multiple control valve and stop valve, realizes there is good control to pump station pressure, reduce high pressure to the damage of hole packer, improve the application life of hole packer.Fully-mechanized mining working high pressure shallow holes irrigation device, carries out water filling to coal seam under can realizing lower pressure, reduces the destruction to rib, all plays good effect to gas control and dust prevention and control.
Accompanying drawing explanation
Brief description is made to the content expressed by each accompanying drawing of this manual and the mark in figure below:
Fig. 1 is structural representation of the present invention;
Mark in above-mentioned figure is: 1, main feed tube; 2, Plane stop valve; 3, outlet pipe; 4, flexible pipe; 5, stop valve; 6, hole packer; 7, hydralic pressure gauge; 8, control valve.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operating principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Because dust is excessive in process of coal mining, not only affect underground mining safety but also have a strong impact on workman healthy, necessary first water filling in coal seam, makes coal body compared with moistening in large regions for this reason, thus reduces the dust pollution in recovery process.For making the moistening coal body compared with large regions of water injecting drilling energy, longer water injection time can be obtained, coal body is evenly moistening, water filling and back production non-interference, meet mitigation degree etc. according to the buried depth of the Xiang Dao Bu Ge of fully-mechanized mining working, coal, balkstone, therefore to be parallel to work plane along seam inclination direction at work plane transport, track crossheading and to stamp to, hole or lower to the two-way elongated hole dynamical pressure water infusion mode of boring.
As shown in Figure 1, water during use in main feed tube 1 flows in Plane stop valve 2, water under high pressure flows to outlet pipe 3 by Plane stop valve 2, one end plug of outlet pipe 3 is blocked, and one end of flexible pipe 4 is connected with outlet pipe 3 by stop valve 5, and the other end of flexible pipe 4 is connected with hole packer 6, outlet pipe 3 is connected with at least one flexible pipe 4 side by side, the quantity of flexible pipe 4 can increase according to the actual conditions of underground water-injection, and outlet pipe 3 is also provided with hydralic pressure gauge 7, and hydralic pressure gauge 7 can monitor the hydraulic pressure of water filling in real time.
During water filling, hole packer 6 is inserted in coal seam, water under high pressure flows through Plane stop valve 2, outlet pipe 3 and flexible pipe 4 successively by main feed tube 1, hydralic pressure gauge 7 shows water injection pressure, water injection pressure can be regulated by control valve 8 and stop valve 5, control valve 8 and stop valve 5 pairs of water fillings realize second voltage regulation, ensure that water filling is safe and efficient.
Water filling device is as shown in Figure 1 a unit of water filling, can the rest may be inferred connects some groups and carry out water injection work to coal seam when needing.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
