Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology for coal milling equipment, and specifically to a dust suppression device for coal milling equipment. Background Technology

[0002] A coal mill is a machine that crushes coal lumps and grinds them into pulverized coal. It is an important auxiliary equipment for pulverized coal boilers.

[0003] Currently, the cylindrical coal mill is the most widely used type. The discharge port of this equipment is open, and it generates a large amount of coal dust during operation, which not only pollutes the environment but also endangers people's health. Therefore, a dust suppression device for coal mill equipment is proposed to facilitate dust suppression spraying at the discharge port of the equipment, thereby achieving the dust suppression effect. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a dust suppression device for coal milling equipment, which facilitates dust suppression spraying at the equipment discharge point, thereby achieving the dust suppression effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is a dust suppression device for coal grinding equipment, including a movable base. A water tank is bolted to one side of the top of the movable base, and a micro water pump is bolted to the top of the water tank. A support rod is provided on the other side of the top of the movable base, and an adjustment component is provided around the support rod. The adjustment component includes a lifting sleeve, a support frame, and positioning bolts. The lifting sleeve is sleeved around the support rod, and a spray component is provided on one side of the support frame.

[0006] The spray assembly includes a support pipe, an arc-shaped spray pipe, and an atomizing nozzle. The arc-shaped spray pipe is connected to the bottom of the support pipe, and the atomizing nozzle is evenly connected to the bottom of the arc-shaped spray pipe from left to right.

[0007] By adopting the above technical solution, the device is moved to the coal milling equipment by using the brakeable rollers at the bottom of the mobile seat, and the arc-shaped nozzle is aligned with the discharge port of the coal milling equipment. Then, the sealing plug is opened and water is injected into the equipment through the water inlet pipe.

[0008] By using a support rod in conjunction with a lifting sleeve to support the support frame, the support pipe is raised and lowered according to the position of the coal mill outlet, so that the arc-shaped spray pipe is in the optimal spray cooling position. Then, the positioning bolt is rotated to squeeze the support rod to position the lifting sleeve, thereby greatly improving the convenience of adjustment.

[0009] During operation, a miniature water pump draws water from the water tank through a pipeline and supplies it to the water delivery hose. The water is then transported from the hose to the support pipe and the arc-shaped spray pipe, and sprayed out through the atomizing nozzle. This achieves a dust suppression effect at the discharge point of the coal mill, significantly improving the dust suppression efficiency.

[0010] Specifically, a water inlet pipe is connected to one side of the top of the water tank through an opening, and a sealing plug is provided on one side of the water inlet pipe.

[0011] By adopting the above technical solution, a water inlet pipe is used to facilitate the injection of water into the water tank, and the opening of the water inlet pipe is sealed with a sealing plug.

[0012] Specifically, a water delivery hose is connected between the support pipe and the micro water pump. The water inlet of the micro water pump is connected to the water tank through a pipe, and the water outlet of the micro water pump is connected to the water delivery hose.

[0013] By adopting the above technical solution, a micro water pump is used to draw water from the water tank through a pipeline and supply it to the water delivery hose. The water is then delivered to the support pipe and the arc-shaped spray pipe and sprayed out through the atomizing nozzle.

[0014] Specifically, the support frame is located on one side of the lifting sleeve, and a positioning bolt is inserted through a pre-reserved threaded hole on the other side surface of the lifting sleeve corresponding to the position of the support rod.

[0015] By adopting the above technical solution, the support rod and the lifting sleeve support frame are used to drive the support pipe to adjust the height according to the position of the coal mill outlet. Then, the positioning bolt is rotated to squeeze the support rod to position the lifting sleeve, thereby greatly improving the convenience of adjustment.

[0016] Specifically, the support tube is fixed to the bottom of the support frame with screws.

[0017] By adopting the above technical solution, the support frame is used to support and fix the support pipe, so that when the lifting sleeve supports the lifting and adjusting of the support frame, the support frame can move up and down along with the support pipe.

[0018] Specifically, the bottom of the movable seat is equipped with brakeable rollers.

[0019] By adopting the above technical solution, the device can be moved to the coal grinding equipment by using the brakeable rollers at the bottom of the mobile seat, thereby improving the convenience of mobile transportation.

[0020] The beneficial effects of this utility model are:

[0021] The dust suppression device for coal milling equipment described in this utility model works by using a micro water pump to draw water from the water tank through a pipeline and supply it to the water delivery hose. The water is then delivered to the support pipe and the arc-shaped spray pipe and sprayed out through the atomizing nozzle, thereby achieving a dust suppression effect at the discharge point of the coal milling equipment and greatly improving the dust suppression effect.

[0022] The dust suppression device for coal milling equipment described in this utility model uses a support rod and a lifting sleeve to support the support frame and drive the support pipe to be raised and lowered according to the position of the coal milling equipment outlet, so that the arc-shaped spray pipe is in the optimal spraying and cooling position.

The arc-shaped spray pipe 902 is connected to the bottom of the support pipe 901, and the atomizing nozzle 903 is evenly connected to the bottom of the arc-shaped spray pipe 902 from left to right.

[0031] When in use, the device is moved to the coal milling equipment by using the brakeable rollers 2 at the bottom of the movable seat 1, so that the arc-shaped nozzle 902 is aligned with the discharge port of the coal milling equipment, and then the sealing plug 5 is opened to inject water into the equipment through the water inlet pipe 4.

[0032] The support rod 7, together with the lifting sleeve 801, supports the support frame 802 and drives the support pipe 901 to adjust the height according to the position of the coal mill outlet, so that the arc-shaped spray pipe 902 is in the optimal spray cooling position. Then, the positioning bolt 803 is rotated to squeeze the support rod 7 to position the lifting sleeve 801, thereby greatly improving the convenience of adjustment.

[0033] During operation, the micro water pump 6 draws water from the water tank 3 through the pipeline and supplies it to the water delivery hose 10. The water is then delivered from the water delivery hose 10 to the support pipe 901 and the arc-shaped spray pipe 902, and sprayed out through the atomizing nozzle 903, thereby achieving the effect of spraying and dust suppression at the discharge point of the coal mill, which greatly improves the dust suppression effect.
