Description

Technical Field

[0001] This utility model relates to the field of dust collection for polishing equipment, and more particularly to a dust collection device for polishing equipment. Background Technology

[0002] When our factory polishes the products, it generates a lot of dust, which is harmful to the human body and equipment. Therefore, the factory previously used two methods: one was for workers to wear masks and other protective equipment, and the other was to use negative pressure fans to absorb the dust. Although using negative pressure fans to absorb dust is effective, the airflow is difficult to control, and the dust collection chamber and the fan are troublesome to clean. Therefore, based on this technical problem, we designed a dust collection device for polishing equipment. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a dust collection device for polishing equipment, including a dust collection chamber body, a water outlet, and a negative pressure fan; the dust collection chamber body has an L-shaped box structure with its side profile forming an "L" shape; an L-shaped opening is provided on the inner side of the dust collection chamber body, and a grinding machine shaft insertion hole is provided on the lower side of the side plates on both sides of the vertical section of the L-shaped opening; an L-shaped partition is provided in the middle of the side profile of the dust collection chamber body, dividing the dust collection chamber body into two sections. The side closest to the opening is the polishing area, and the other side separated by the L-shaped partition is the dust collection water tank area below, with a negative pressure air duct above it. An air outlet is provided at the top of the negative pressure air duct, and a negative pressure fan is provided at the air outlet. The water level in the dust collection water tank is higher than the height of the bottom horizontal plate of the L-shaped partition. A dust suction port is provided on the L-shaped partition above the water level in the dust collection water tank. A water outlet is provided at the top of the dust suction chamber body between the opening and the L-shaped partition, and a water faucet is connected to the water outlet. A drain outlet is provided on one side of the bottom of the dust collection water tank.

[0004] The vertical section of the L-shaped partition is provided with a vertical air duct partition on the side away from the opening, and the bottom of the air duct partition is submerged in the water surface of the dust collection tank.

[0005] The dust collection water tank has an outwardly protruding water tank cleaning observation port on the side away from the opening. The opening of the water tank cleaning observation port faces upward and the height of the opening is higher than the bottom height of the air duct partition.

[0006] The L-shaped partition has a transitional sloping plate at the bend, the dust suction port is located on the sloping plate, and the bottom two sides of the L-shaped partition have connecting grooves.

[0007] An L-shaped protective plate is provided between the L-shaped partition and the opening. The bent end of the protective plate is arc-shaped. The arc-shaped part and the bottom horizontal plate part of the protective plate are grid plates. A water outlet is provided on the top edge of the protective plate near the opening. The water coming out of the water outlet sprays onto the protective plate.

[0008] A first return water hole is provided on one side of the dust collection water tank. The height of the first return water hole is higher than the bottom horizontal plate of the L-shaped partition and the bottom of the air duct partition. Three water outlet holes are evenly arranged horizontally along the L-shaped partition. Two second return water holes are arranged between each pair of the three water outlet holes. The two second return water holes are connected to the top horizontal pipe through a hose. One end of the horizontal pipe is connected to a water pump, and the other end of the water pump is connected to the first return water hole.

[0009] The beneficial effects of this utility model are as follows:

[0010] This device uses clean water, a duct partition, and a dust suction port to form an air duct, drawing in polishing dust through the suction port. A water curtain, sprayed onto a protective plate and formed by the suction port under the force of the airflow, tilts towards one side of the air duct. The water curtain and the sucked-in dust merge into the water tank, preventing the dust from entering the upper part of the negative pressure air duct. Instead, the dust dissolves in the water as wastewater, allowing for better subsequent wastewater treatment. The device also eliminates the need for long-term fan cleaning, reducing the workload for workers. Attached Figure Description

The lower side of the L-shaped partition is a dust collection water tank area 7, and the upper side is a negative pressure air duct 8. An air outlet 9 is provided at the top of the negative pressure air duct, and a negative pressure fan is provided at the air outlet. The water level in the dust collection water tank is higher than the height of the bottom horizontal plate of the L-shaped partition. A dust suction port 10 is provided on the L-shaped partition above the water level in the dust collection water tank. A water outlet 2 is provided at the top of the dust suction chamber body between the opening and the L-shaped partition. A water faucet is connected to the water outlet. A sewage outlet 11 is provided on one side of the bottom of the dust collection water tank.

[0019] A vertical air duct baffle 12 is provided on the side of the vertical section away from the opening of the L-shaped baffle, and the water surface of the dust collection tank is submerged below the air duct baffle. The water level should be above the bottom of the air duct baffle 12 and the bottom of the L-shaped baffle 6, so that a unidirectional airflow will be generated when the negative pressure fan draws air.

[0020] The dust collection water tank has an outwardly protruding water tank cleaning observation port 13 on the side away from the opening. The opening of the water tank cleaning observation port faces upward, and the height of the opening is higher than the bottom height of the air duct partition. The water tank cleaning observation port and the air duct are separated by the air duct partition 12 and water.

[0021] The L-shaped partition has a transitional sloping plate 14 at the bend, the dust suction port is located on the sloping plate, and the bottom sides of the L-shaped partition have connecting grooves 15.

[0022] An L-shaped protective plate 16 is provided between the L-shaped partition and the opening. The bent end of the protective plate is arc-shaped. The arc-shaped part and the bottom horizontal plate part of the protective plate are grid plates 17. A water outlet hole is provided on the top edge of the protective plate near the opening. The water coming out of the water outlet hole sprays onto the protective plate.

[0023] A first return water hole 18 is provided on one side of the dust collection water tank. The height of the first return water hole is higher than the bottom horizontal plate of the L-shaped partition and the bottom of the air duct partition. The height of the first return water hole is lower than the water tank cleaning observation port. Three water outlet holes are evenly arranged horizontally along the L-shaped partition. Two second return water holes 19 are arranged between each pair of the three water outlet holes. The two second return water holes are connected to the top horizontal pipe 20 through a hose. One end of the horizontal pipe is connected to the water pump 21, and the other end of the water pump is connected to the first return water hole.

[0024] Specific operations

[0025] Before polishing, depending on the site location and worker operation needs, insert the polishing machine's shaft into either side of the grinding machine shaft insertion hole 5. After insertion, install the polishing wheel, turn on the external water tap or pour clean water directly from the water tank cleaning observation port 13 into the dust collection water tank area 7. The water level should cover the bottom of the air duct partition 12 and the bottom of the L-shaped partition 6, and also cover the first return water hole. After water filling is complete, start the water pump and begin polishing. The water flowing out of the second return water hole 19 sprays onto the protective plate 16 and the mesh plate 17. Most of the water forms an inwardly curved water curtain at the dust suction port under the action of the negative pressure fan. The suction port generates negative pressure, absorbing the dust generated during polishing that falls into the water. Some of the dust mixes with the water curtain and enters the water tank. Because the air duct is large, the negative pressure fan will not suck the water upwards, allowing the dust to dissolve in the water. When the water becomes cloudy, the drain outlet 11 can be opened to drain the wastewater. If polishing needs to continue, the faucet can be turned on to allow clean water to flow from the outlet 2 to absorb the dust in the same way. If polishing is not needed, the drain outlet 11 can be opened to drain the wastewater, and a mop can be inserted into the water tank to clean the observation port 13 to flush out the dirt attached to the bottom along with the wastewater.
