Abstract
The utility model relates to a coal storehouse arch-breaking device, comprising a water source, a one-way valve, a pressure pump, a safety valve, a pressure gauge, a high-pressure pipe and a bell-mouth nozzle. The port and the lateral wall of the high-pressure pipe are respectively welded with a bell-mouth nozzle, high pressure water is sprayed to the roof arch and the vertical arch of the coal storehouse through the bell-mouth nozzle, in this way, the roof arch and the vertical arch are broken simultaneously and safely to reach the smoothness for material to travel. The utility model has the advantages of simple operation and energy saving, and the coal storehouse arch-breaking device can prevent a human injury. As the utility model makes full use of the existing water source in coal mine underground, as the utility model can guarantee the personal safety of a worker, the coal storehouse arch-breaking device is welcomed by the worker.
Description
The utility model is the arch breaking apparatus about silo, is mainly used in coal bunker, and is also suitable to the storehouse of other loose unpacked materials.
After amassing coal in the coal bunker, before the Hatch Opening gate opening, the coal amount three received strength effect of arbitrary cell cube, form state of equilibrium, after the Hatch Opening gate opening owing to fall part of coal, thereby destroyed original balance, the stress redistribution, form new balance, interface after its balance becomes stable parabola canopy arch, simultaneously in the storehouse material in flow process be with along one from the horizontal by 45 °+(φ)/2 jiao a sliding surface to lower slider (φ is the angle of internal friction of material), when its gravity can not overcome frictional resistance to bulkhead, just formed a Yu Mei district again, " vertically encircleing " named in this Yu Mei district usually.Whole coal bunker is to form vertical arch earlier then to form the canopy arch in the process that arch becomes.The formation of arch badly influences flowing of material, brings difficulty to transit link, has only by broken arch to guarantee material Channel Group.
At present the device of broken arch has: 1. ear of maize.Promptly carry out under the coal bunker mouth with ear of maize by manpower, it is poor to have occurred operating conditions like this, and labour intensity is big, is easy to cause the phenomenon of human casualty accident, and in fact this accident happens occasionally under coal mine.2. mechanical vibrator.Adopting mechanical vibrator to break arch can only be to the canopy effect of arching upward, and long as the coal resting period, under the situation of ature of coal difference, shake is real more more on the contrary to adopt mechanical vibrator, poor effect.3. steam arch breaking apparatus.Adopt this device can not become a reality to borehole operation such as collieries.4. air plant.Adopt the air plant equipment investment big, period of service is few, and it is big to consume air quantity, share wind regime and produce interference again under coal mine, big to viscosity simultaneously, contains the higher coal of moisture and can only be blown a hole and do not have brokenly arch action.
The purpose of this utility model is to overcome the shortcoming of said apparatus.Can finish brokenly the canopy arch and can finish brokenly vertical arch again, make full use of the water source under the coal mine, save power consumption, guarantee workman's personal safety.
The coal bunker arch breaking apparatus is made up of water source, check valve, force lift, compression indicator, high-pressure pipe, safety valve and exit skirt nozzle.The high-pressure pipe of broken canopy arch and broken vertical arch all needs more than two, the high tension terminal head part of broken canopy arch needs according to the coal bunker bending, the high-pressure pipe port is welded with the exit skirt nozzle, be welded with two above exit skirt nozzles on the sidewall of high-pressure pipe termination, the exit skirt nozzle of high-pressure pipe port is hmin=200-350mm apart from the height of coal bunker mouth, and the exit skirt nozzle on the high-pressure pipe sidewall is 500-700mm apart from the exit skirt nozzle height on the high-pressure pipe port.The high-pressure pipe port of broken vertical arch is welded with the exit skirt nozzle, is welded with two above exit skirt nozzles on its sidewall, and the exit skirt nozzle on the high-pressure pipe port is L-(400-700 apart from the height of coal bunker mouth) mm, wherein:
L＝（R－L
1）t
ga
R---tower silo radius when storehouse (square be the length of side)
L
1---circular coal bunker port radius (during coal bunker mouth squarely is the length of side)
α＝45°＋ (φ)/2
The angle of internal friction of φ---coal
The exit skirt nozzle that welds on the high-pressure pipe port of broken canopy arch and broken vertical arch becomes the angle less than 90 ° with horizontal surface, the exit skirt nozzle on the pipe side becomes the angle less than 90 ° with tube wall.
The water that comes from the water source sprays to vertical arch and canopy arch through check valve, force lift, compression indicator, safety valve, high-pressure pipe and exit skirt nozzle.The high-pressure pipe of broken canopy arch leads to canopy arch district along the coal bunker inwall, the high-pressure pipe of broken vertical arch leads to vertical arch district along the coal bunker inwall, can make full use of the water source, down-hole under coal mine, when hydrostatic pressure can not meet the demands, the restart pressure pump can be saved power consumption like this.
Adopt this coal bunker arch breaking apparatus safely and reliably canopy arch and vertical arch to be destroyed simultaneously, it is without hindrance to reach material Channel Group, this device is simple to operate, can prevent the generation of fatal accident, owing to made full use of the existing water source under the coal mine, so can save power consumption, extremely the welcome of coal miner.
1 to 2 represented embodiment describes in detail the utility model below in conjunction with accompanying drawing
Accompanying drawing 1 is a schematic diagram of the present utility model
Accompanying drawing 2 is pack into section-drawings behind the coal bunker of high-pressure pipe
Wherein:
1---water source 2---check valve
3---force lift 4---compression indicator
5---high-pressure pipe 6 of broken canopy arch---high-pressure pipe of broken vertical arch
7---safety valve 8---exit skirt nozzle
Embodiment of the present utility model, be used for the cylinder coal bunker, 2. 1. the water source connect I 63 check valves through high-pressure pipe, 2. connect BL type associated mode centrifugal pump 3. through check valve after, 3. the high pressure moisture two-way that comes out from centrifugal pump through the y-150T compression indicator 4., the high-pressure pipe that 7. A41Y-16P type safety valve leads to brokenly canopy arch and broken vertical arch respectively is 5. and 6., 6. 5. broken canopy sagitta pressure pipe all select three with broken vertical sagitta pressure pipe, broken canopy arch and every high-pressure pipe of broken vertical arch 6. and termination mouth 6. weld an exit skirt nozzle, respectively weld three exit skirt nozzles on the sidewall.
