Description

Technical Field

[0001] This utility model specifically relates to the field of dust suppression technology, and more specifically to a dust suppression mechanism for dusty exhaust gas. Background Technology

[0002] With the rapid development of industry, a large amount of waste gas containing dust is generated in various industrial production processes. For example, industries such as mining, metallurgy, chemical industry, building materials, and power release a large amount of dust in processes such as ore crushing, material transportation, and combustion. If this dust is discharged directly into the atmosphere without effective treatment, it will cause serious environmental pollution and endanger the ecological balance and human health.

[0003] Traditional dust suppression devices collect dust-laden exhaust gas and allow the dust to settle naturally under gravity. This method is inefficient and cannot achieve continuous operation during settling. Another method is to separate the exhaust gas to suppress dust. However, when a large amount of dust enters the separation device, it may cause blockage. If the separation device is not cleaned or replaced in time, the dust suppression efficiency cannot be guaranteed.

[0004] A search revealed Chinese Patent Publication No. CN202321930472.8, which discloses a dust suppression mechanism. The mechanism includes a main body for dust suppression, comprising a processing operation panel and a support frame. The processing operation panel is located on the upper surface of the support frame. By designing a uniform dust suppression mechanism, when wood processing and sanding generates debris on the main body of the dust suppression device, a protective cover can be used to centrally protect the debris. An external air pump is installed at the mounting port and air is drawn in through a hollow box. During air intake, four suction heads simultaneously and uniformly collect the dust. The debris drawn in by the suction heads is then drawn into the interior of the hollow box through a connecting flexible tube and collected in a collection box for reuse.

[0005] When the device in the aforementioned patent is in use, it extracts the exhaust gas through the dust suction head and collects the dust into the collection box. The dust and exhaust gas are separated by gravity. This method has low dust reduction efficiency and cannot be used in continuous dust reduction working environments. Utility Model Content

[0006] The purpose of this invention is to provide a dust collection mechanism for exhaust gas containing dust. In this device, a negative pressure fan collects the dust-containing exhaust gas into an inclined pipe. A first drive motor rotates the spiral blades to effectively transport the dust-containing exhaust gas. During the transport process, the dust and exhaust gas are effectively separated. A second drive motor then rotates the inclined pipe to transport the separated dust through through holes on the side wall of the inclined pipe to a discharge rack, thereby solving the problems mentioned above in the background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dust suppression mechanism for dusty exhaust gas includes a frame; an inclined tube is provided inside the frame; rollers are installed at both ends of the inclined tube; the rollers are movably installed in a mounting frame, which is fixedly installed to the inner wall of the frame via a fixed frame.

[0009] The inclined tube is fitted with a helical blade; one end of the shaft of the helical blade is fixedly installed with the first drive motor; the end of the inclined tube away from the first drive motor is provided with multiple collection holes.

[0010] As a further technical solution of this utility model, a driven gear is fixedly installed on the inclined tube; the bottom of the driven gear meshes with the driving gear; the driving gear is fixedly installed on the output shaft of the second drive motor; the second drive motor is fixedly installed by a mounting plate; both ends of the mounting plate are fixedly installed to the inner wall of the frame.

[0011] As a further technical solution of this utility model, a material discharge rack is installed at the bottom of one end of the inclined tube where the first drive motor is installed, and the material discharge rack is fixedly installed with the frame body; multiple through holes are opened on the surface of the inclined tube that mates with the material discharge rack.

[0012] As a further technical solution of this utility model, a partition is also fixedly installed at the bottom of the inclined tube; the partition forms a sealed cavity with the inner wall and end of the frame; a negative pressure fan is fixedly installed at the end of the sealed cavity.

[0013] As a further technical solution of this utility model, the bottom of the discharge rack is fitted with the collection cylinder; the collection cylinder is fixedly installed on the bottom plate inside the rack body;

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, this utility model effectively collects dust-containing exhaust gas into the cavity formed by the partition and the frame through a negative pressure fan, and effectively transmits it into the inclined pipe through the collection hole opened at the end of the inclined pipe. The first drive motor drives the spiral blades to rotate effectively, thereby effectively separating the exhaust gas and dust, thus improving the dust reduction efficiency.

[0016] 2. In the dust suppression process, the dust is effectively transported by the rotation of the spiral blades. During the transport process, the dust is discharged through the through holes opened on the side wall of the inclined tube. When the dust transported by the spiral blades needs to be discharged, the second drive motor drives the driven gear to rotate, so that the through holes opened on the side wall of the inclined tube cooperate with the discharge rack, thereby realizing the transfer of dust to the collection cylinder through the discharge rack.

The first drive motor 7 drives the spiral blade 6 to rotate effectively, thereby effectively separating the exhaust gas and dust, thus improving the dust reduction efficiency.

[0032] By adopting the above technical solution, during the dust reduction process, the dust is effectively transported by the rotation of the spiral blades 6. During the transport process, the exhaust gas is discharged through the through holes 17 opened on the side wall of the inclined pipe 5.
