Description
Technical field
External spraying water system in a kind of development machine of the utility model belongs to development machine atomizing de-dusting technical field.
Background technology
In development machine when work,, cutting head of roadheader is to grind to draw in the entity at coal to dig, and can produce bigger abrasive power between its pick and the coal body, and abrasive power is more big more to be easy to generate trickle dust, existing manyly address this problem with atomizing de-dusting.The atomizing de-dusting system mainly is mounted in the inside and outside spraying system on the development machine.Spraying system especially internal spraying be initial stage that dust produces to by cut with treat by cut and just sprayed water smoke by the coal body of cut that wetting coal body and the dust of drawing up play cooling effect to pick simultaneously.External spraying is to stop the dust from flying diffusion, relies on water smoke that cutting head of roadheader is shrouded, and forms the water smoke barrier, stops the diffusion of dust.Therefore the spraying system functional reliability be exactly in the atomizing de-dusting technology outbalance a bit.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of functional reliability height, external spraying water system in the not susceptible to plugging development machine of nozzle.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: external spraying water system in a kind of development machine, comprise static pressure water water supply line, motor cooling water supply line, the internal spraying water supply line, down-hole static pressure water, y-type filter, ball valve, reducing valve, tank cooler, atomizing pump and development machine, one end of motor cooling water supply line and internal spraying water supply line all is communicated with down-hole static pressure water by static pressure water water supply line, the other end of motor cooling water supply line is connected with the cutting motor water inlet of development machine, the cutting motor delivery port of development machine is connected with external spraying nozzle on the development machine, and the other end of internal spraying water supply line is connected with internal spraying nozzle on the development machine;
On the described static pressure water water supply line y-type filter and ball valve are installed;
On the described motor cooling water supply line reducing valve and tank cooler are installed successively;
On the described internal spraying water supply line atomizing pump is installed.
Between described motor cooling water supply line top tank cooler and the reducing valve shock-proof pressure gauge is installed.
On the described internal spraying water supply line internal spraying pressure meter is installed.
The utility model is compared the beneficial effect that has with prior art: the utility model filters through y-type filter earlier after down-hole static pressure water enters pipeline, static pressure water after the filtration has reduced the obstruction probability of pipeline or nozzle, divide two-way again, one the tunnel provides cooling water for cutting motor, the back is sprayed by the external spraying nozzle, another road is that internal spraying supplies water through atomizing pump directly, the type selecting of spraying pumping plant only need satisfy pressure and the flow of internal spraying like this, both provided cost savings, guarantee pressure and flow that internal spraying is required again, improved the dependability of spraying system.
