Description

Technical Field

[0001] This utility model relates to the field of waste gas emission technology, and more specifically, to an exhaust device that facilitates the discharge of dust-laden gas from a workshop. Background Technology

[0002] Engraving machines generate a lot of dust during the processing of parts. This dust will spread into the air in the factory. If this dusty air is not removed in time, it will have a great impact on the health of the workers.

[0003] The existing dust extraction systems in some factories have the following drawbacks: the suction ducts are prone to blockage and the extraction effect is poor. The original suction ducts of the engraving machine are very easy to blockage and require frequent maintenance; the labor cost is high and the duct extraction effect is poor, requiring a dedicated person to clean the dust every month.

[0004] Therefore, an exhaust device that facilitates the removal of dust-laden gases from the workshop is proposed. Utility Model Content

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] An exhaust device for facilitating the removal of dust-laden gas from a workshop includes a dust suction hood 201 installed above the workbench 101 of a carving machine. The dust suction hood 201 is installed on the indoor ceiling via a mechanism that allows its height to be adjusted, such as a hydraulic rod. This allows the height of the dust suction hood 201 to be adjusted as needed, so that the exhaust device can remove dust-laden air from different height ranges.

[0022] Specifically, the exhaust system includes a main air duct 401, a first air pump (not shown in the figure), and a dust collector 402 connected in sequence. An equipment box 501 is installed on one side of the dust collection hood 201, and the first air pump is installed inside the equipment box 501. The air inlet of the first air pump is connected to the main air duct 401, and its exhaust outlet is connected to the dust collector 402 via a pipe. The end of the main air duct 401 away from the first air pump extends into the dust collection hood 201. Several branch pipes 403 are installed at intervals on the section of the main air duct 401 inside the dust collection hood 201. Several suction pipes 404 are installed at intervals on any branch pipe 403. The suction pipes 404, branch pipes 403, and main air duct 401 are connected in sequence. (Refer to...) Figure 2 In this embodiment, there are two main air ducts 401, both of which are connected to the air inlet of the first air pump. Each main air duct 401 is equipped with several branch pipes 403 at intervals, and each branch pipe 403 is equipped with several suction pipes 404. The suction port of each suction pipe 404 faces the worktable 101 of the engraving machine. This design can increase the air intake of the main air ducts 401, thereby quickly drawing the dusty air above the worktable 101 of the engraving machine into the main air ducts 401 through the first air pump, and then into the dust collector 402 for dust removal before being discharged to the outside.

[0023] As dusty air flows within the main duct 401, dust will accumulate on the inner wall of the main duct 401 over time. To facilitate the cleaning of this accumulated dust, the exhaust system also includes a dust removal unit installed inside the main duct 401.

[0024] Specifically, in this embodiment, the dust removal unit includes an aeration pipe installed inside the main air duct 401 and a second air pump (not shown in the figure) installed inside the equipment box 501. The aeration pipe has several air jet holes 601 spaced apart. One end of the aeration pipe is connected to the exhaust port of the second air pump, and the air inlet of the second air pump is connected to the exhaust pipe of the dust collector 402. Thus, part of the gas treated by the dust collector 402 is discharged to the outside, while the other part can be used by the second air pump to draw it into the aeration pipe. The gas in the aeration pipe is sprayed at a certain pressure through the air jet holes 601 onto the inner wall of the main air duct 401 to blow off the dust deposited on the inner wall of the main air duct 401. Then, this fallen dust, along with the dust-laden air, is drawn into the dust collector 402 by the first air pump. This design allows for simultaneous cleaning of the dust deposited in the main air duct 401 during the first air pump's extraction process, which is convenient and quick.

[0025] Reference Figure 3 or Figure 4To further enhance the dust removal effect of the dust removal unit, in this embodiment, the aeration pipe includes several dust removal pipes 602 connected in sequence. Each dust removal pipe 602 has several air jet holes 601. Adjacent dust removal pipes 602 are rotatably connected, and each dust removal pipe 602 is rotatably connected to the main air duct 401. Each dust removal pipe 602 is equipped with a fan blade 701. Thus, as the dust-laden air in the workshop flows within the main air duct 401 under the suction of the first air pump, if the second air pump operates simultaneously for dust removal, the dust-laden air with a certain flow velocity within the main air duct 401 will impact the fan blades 701, driving each dust removal pipe 602 to rotate. During the rotation of each dust removal pipe 602, the gas ejected through each air jet hole 601 will impact the sidewalls at different locations within the main air duct 401, thereby further enhancing the dust removal effect of the dust removal unit.

[0026] In other embodiments of this example, the air inlet of the second air pump can also be connected to the outside, so that the second air pump can be used to clean the dust when the first air pump is not working.

[0027] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
