Referring to fig. 1 to 4, the present invention provides a specific technical embodiment of a double-hole fan nozzle:
a double-hole fan-shaped nozzle for coal dressing and medium removal comprises a base 2, a hexagon 3 and a cylinder 1 from top to bottom; the base 2, the hexagon 3 and the inner channel of the cylinder 1 form a water inlet channel 4, and the water inlet channel 4 comprises a first channel section 5, a second channel section 6 and spray pipes 7 which are obliquely and symmetrically distributed on two sides of the central axis of the spray head from top to bottom; the bottom of the cylinder 1 is provided with V-shaped grooves 8 which are symmetrical about the central axis of the nozzle and penetrate through a hemispherical groove 9 arranged at the bottom end of the spray pipe 7 to form a long and narrow elliptical nozzle.
Specifically, the first channel section 5 is arranged in an inverted cone shape, and the side wall of the first channel section 5 and the top end of the second channel section 6 form a corner of 84-88 degrees. The tapered flow channel enables the flow channel to be uniformly and smoothly narrowed, and the design enables the jet flow to always do accelerated motion at the inlet section, so that the speed is maximum when the jet flow reaches the outlet, the impact strength of the water flow is improved, the non-uniform spraying caused by unstable water pressure factors is reduced, the liquid mist distribution is more refined and uniform, and the stability of the nozzle during spraying is improved; and the area of the corner presenting the low speed state is very small, and the energy loss is little.
Specifically, the second channel section 6 is cylindrical and provides a guiding function for the water flow.
Specifically, the spray pipes 7 are obliquely and symmetrically distributed on two sides of the central axis of the nozzle and form an included angle of 25-30 degrees with the axis. The structure ensures that the sector is large in expansion angle, the water flow impact force is larger, the spray surface is more uniform, and a better cleaning effect is achieved.
Specifically, the V-shaped groove 8 is symmetrical about the central axis of the nozzle and intersects with the inner hemispherical groove 9 to form a long and narrow elliptical spout, so that the edge boundary of the spray shape is clearer.
Specifically, the hemispherical recesses 9 are provided at the bottom end of the nozzle and are symmetrically distributed about the centre line of the nozzle 7. The hemispherical groove 9 provides a guiding function for water flow discharged by spraying, and forms a 80-120-degree fan-shaped spraying angle by matching with the V-shaped groove 8, so that the spraying coverage is enlarged, and the using effect of the nozzle is improved.
The method comprises the following specific implementation steps:
when the device is used, the base 2 is connected with a water pipe in a threaded screwing mode, the side wall of the first channel section 5 and the top end of the second channel section 6 form a corner of 84-88 degrees, so that a flow channel is uniformly and smoothly narrowed, the jet flow always performs accelerated motion in the inlet section due to the design, the speed is maximum when the jet flow reaches an outlet, the impact force of the water flow is improved, the non-uniform spraying caused by unstable water pressure factors is reduced, the liquid mist distribution is more refined and uniform, and the stability of the spray nozzle during spraying is improved; and the area of the corner presenting a low-speed state is very small, the energy loss is very little, and the spray pipes 7 are obliquely and symmetrically distributed on two sides of the central axis of the nozzle and form an included angle of 25-30 degrees with the axis. This structure makes the sector expansion angle big, and the water impact force is bigger, and the injection face is more even, reaches better cleaning performance, and V type groove 8 is symmetrical about the nozzle center axis, passes through mutually with inside hemisphere recess 9 moreover, forms long and narrow oval spout for the border of spraying shape is more clear. When needs inspect or change the nozzle, operating personnel holds this nozzle device's hexagon 3 with the hand, carries out anticlockwise rotation for the screw thread of base 2 is through the helicitic texture phase separation in clockwise and the water pipe, dismantles the completion back, carries out the nozzle of more renewing, and operation process is comparatively simple labour saving and time saving.
In conclusion: according to the double-hole fan-shaped nozzle for coal dressing and medium removal, the water inlet channel with the conical channel section is formed, so that a throttling corner is formed on the inner wall of the water inlet channel, a flow channel is uniformly and smoothly narrowed, and jet flow always performs accelerated motion at the inlet section, so that the speed is maximum when the nozzle reaches an outlet, the impact force of water flow is improved, the non-uniform spraying caused by unstable water pressure factors is reduced, the liquid mist distribution is more refined and uniform, and the stability of the nozzle during spraying is improved; the area of the corner in a low-speed state is very small, and the energy loss is little; through setting up twice spray tube about nozzle central axis slope symmetric distribution for sector expansion angle is big, and the rivers impact force is bigger, and the spray face is more even, reaches better cleaning performance.
