Abstract
The utility model is related to atomizing de-dusting field, the fully-mechanized digging machine atomizing de-dusting apparatus that is used on especially a kind of coal mine.A kind of atomizing de-dusting apparatus applied on fully-mechanized digging machine, external source connects the cooling water pipe (1) of fully-mechanized digging machine by external pipe (6), a branch pipe (2) is drawn from the cooling water pipe (1) of fully-mechanized digging machine, branch pipe (2) is linked in sequence after pressure reducing valve (3) and resistanceization pump (4) by pipeline and is connected on nozzle (5).Cost is not only reduced by using the utility model, and improves safety.
Description
Technical field
The utility model is related to atomizing de-dusting field, the fully-mechanized digging machine atomizing de-dusting apparatus that is used on especially a kind of coal mine.
Background technology
2016 editions《Safety regulations in coal mine》It is required that fully-mechanized digging machine external spraying operating pressure is not less than 4MPa.Traditional solution
It is that 2MPa is reduced to using pressure reducing valve in cooling motor on fully-mechanized digging machine in the pressure of the water supply offer 4MPa in tunnel.It is susceptible to
Development end feed pipe uses high-voltage tube, of high cost.The phenomenon that water supply capacity waste of water supply pump.
Utility model content
Technical problem to be solved in the utility model is：How mining costs water supply in terms of are reduced.
Technical solution used by the utility model is：A kind of atomizing de-dusting apparatus applied on fully-mechanized digging machine, outside water
Source connects the cooling water pipe of fully-mechanized digging machine by external pipe, and a branch pipe is drawn from the cooling water pipe of fully-mechanized digging machine, and branch pipe passes through
Pipeline is linked in sequence after pressure reducing valve is pumped with resistanceization and is connected on nozzle.
As a kind of preferred embodiment：The hydraulic pressure of external pipe is 2MPa, is 0 by the hydraulic pressure after pressure reducing valve, passes through nozzle
Hydraulic pressure be 4MPa.
The utility model has the beneficial effects that：The utility model reduces the hydraulic pressure of cooling water pipe water inlet line, reduces
Avoid the cost using high-voltage tube.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is prior art construction schematic diagram；
Specific implementation mode
As shown in Fig. 2, in the prior art, external pipe 6 needs to introduce tunnel using the high-pressure water pipe that can bear 4MPa,
Then it is divided into two-way, is connected to all the way on nozzle 5 and carries out spray operations, hydraulic pressure is reduced to by another way by a pressure reducing valve 3
Fully-mechanized digging machine is cooled down after 2MPa, the needs of external pipe 6 are the high-pressure water pipes that can bear 4MPa.
As shown in Figure 1, the utility model improves the prior art, external source is connected comprehensive by external pipe 6
The cooling water pipe 1 of pick machine, draws a branch pipe 2 from the cooling water pipe 1 of fully-mechanized digging machine, and branch pipe 2 is linked in sequence decompression by pipeline
It is connected on nozzle 5 and sprays after valve 3 and resistanceization pump 4.The hydraulic pressure of external pipe 6 is 2MPa, passes through the hydraulic pressure after pressure reducing valve 3
It is 0, the hydraulic pressure by nozzle 5 is 4MPa.It can be seen that by the improvement of the utility model, external pipe 6 can be used and only be needed
The low pressure water pipe of 2MPa can be born, and it is cheap many in the high-pressure water pipe price of the low pressure water pipe ratio 4MPa of 2MPa,
It is and also safer, it is not easy to leakage phenomenon occur.
