Description

Technical Field

[0001] This invention relates to a V-shaped spray head capable of expanding the dust suppression range, which is used for spraying dust suppression when a coal mine is transported by a belt conveyor, and belongs to the field of underground dust suppression technology. Background Technology

[0002] During coal mining, belt conveyors are typically used to transport the mined coal. The coal falls from the conveyor head into mine cars. During this descent, the coal moves in a parabolic trajectory, and smaller coal dust particles attached to the coal are thrown into the air, forming dust. This dust, floating in the air, is detrimental to the health of workers and pollutes the underground environment. Therefore, belt conveyors are generally equipped with spraying equipment for dust suppression. However, existing spraying equipment on belt conveyors typically sprays dust outwards along the centerline of the nozzle, forming only a small dust-suppressing spray column with a limited coverage area, making it difficult to effectively suppress airborne dust.

[0003] Publication number CN208716457U discloses an automatic spraying device suitable for mining belt conveyors, including a baffle, a chute, a fixing hole, and a crossbar. The front surface of the baffle is nested with a chute, and the front surface of the chute is nested with a fixing hole. A crossbar is fixedly connected to the top of the baffle. The crossbar includes a spray head, a pipe, a sliding plate, and fixing nails. The bottom surface of the crossbar is movably connected to the spray head, and the top surface of the spray head is fixedly connected to a pipe. A water pump is fixedly connected to one side of the pipe. Sliding plates are fixedly connected to the inside of the left and right sides of the crossbar. Fixing nails are nested on the upper and lower surfaces of the sliding plates, and the fixing nails are engaged with the fixing holes. The spraying device sprays dust along the center line of the nozzle, forming only a dust-suppressing spray column with a small spray range, making it difficult to effectively suppress dust diffused in the air.

[0004] Publication number CN208364166U discloses an automatic spraying and watering device next to a belt conveyor; it includes a water pipe equipped with a solenoid valve, and several nozzles connected to the end of the water pipe. The nozzles are located above the belt of the belt conveyor. The solenoid valve is connected to a set of normally open contacts of the protective electrical control box of the belt conveyor via a cable and is connected in series with the 36V power supply of the protective electrical control box. The spraying and watering device sprays dust along the center line of the nozzles, forming only a dust-suppressing spray column with a small spray range, making it difficult to effectively suppress dust diffused in the air.

The dust suppression spray head is installed above the head of the belt conveyor through the installation flange. The water injection support pipe (5) is parallel to the belt and is connected to the high-pressure water pump connection pipe. When the belt conveyor transports coal, water is injected into the water injection support pipe (5) through the high-pressure water pump.

The single set of ellipsoidal baffles (10) is located between two adjacent spray heads (3). The two rows of ellipsoidal baffles (10) in the same set are equidistantly distributed between two adjacent spray heads (3). The multiple ellipsoidal baffles (10) in the same row are equidistantly distributed along the length of the spray box (1). When in use, the ellipsoidal baffles (10) can better block and turbulent the sprayed water mist, and expand the spray range of the water mist. Example 3: The difference between this embodiment and embodiment 1 is that the baffle (4) is replaced by an arc-shaped baffle (11), and the spray box (1) is equipped with multiple sets of arc-shaped baffles (11). One set of arc-shaped baffles (11) consists of two rows of arc-shaped baffles (11), and one row of arc-shaped baffles (11) consists of multiple arc-shaped baffles (11). The single set of arc-shaped baffles (11) is located between two adjacent spray heads (3). The two rows of arc-shaped baffles (11) in the same set are equidistantly distributed between two adjacent spray heads (3). The multiple arc-shaped baffles (11) in the same row are equidistantly distributed along the length of the spray box (1). When in use, the arc-shaped baffles (11) can better block and turbulent the sprayed water mist, and expand the spray range of the water mist. Example 4: The difference between this embodiment and embodiment 1 is that the baffle (4) is replaced by a triangular baffle (12), and the spray box (1) is equipped with multiple sets of triangular baffles (12). One set of triangular baffles (12) consists of two rows of triangular baffles (12), and one row of triangular baffles (12) consists of multiple triangular baffles (12). The single set of triangular baffles (12) is located between two adjacent spray heads (3).

The multiple triangular baffles (12) in the same row are equidistantly distributed along the length of the spray box (1). When in use, the triangular baffles (12) can better block and turbulent the sprayed water mist, and expand the spray range of the water mist. The spray box (1) is designed with a V-shaped structure, which can expand the spraying range of water mist; The design of the center line of the reinforced water injection pipe (6) and the center line of the water injection support pipe (5) forming an acute angle can support and reinforce the spray box, making it more stable when injecting water into the spray box and spraying water mist. The spray head (3) has a long strip structure and the cross-section of the spray head (3) is an isosceles trapezoidal structure, which can expand the spray angle of the spray side holes (9) on both sides and expand the spray range; The design that the width of the spray hole (8) gradually increases from one end of the spray head (3) to the other end, and the width of the spray side hole (9) gradually increases from one end of the spray head (3) to the other end, can expand the spray range of water mist; The design of the center line of the spray side hole (9) and the center line of the spray head (3) forming an acute angle makes it easier for the water mist to spray around the spray head and expand the spray range. The water diversion block (7) is designed with an arc shape, which can better divert the water flowing into the spray box (1), so that it can quickly fill the spray box (1) and spray water mist more quickly to reduce dust in the air. The two water diversion blocks (7) are located in the middle of the spray box (1). The two water diversion blocks (7) are symmetrically distributed about the center line of the spray box (1). The gap between the two water diversion blocks (7) is connected to a set of connecting grooves (2) located in the middle of the spray box (1). This design allows the set of connecting grooves (2) located in the middle of the spray box (1) to be avoided, so that the spray head in the middle of the spray box (1) can spray and reduce dust normally. The design of the single-group baffle (4) located between two adjacent spray heads (3) can block and turbulent the water mist sprayed from the spray side hole (9), further expanding the spray range of the water mist; The spray box, spray head and baffle (4) work together to expand the spray range of water mist and better suppress dust that diffuses in the air. The spray box (1) with its V-shaped structure, combined with the spray heads (3) evenly distributed on it, expands the spraying range and better reduces dust that diffuses in the air.
