Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, and more specifically to a mobile semi-sealed collection hood with an air curtain. Background Technology

[0002] The pain points of dust control in metallurgical production: The dust generation process is complex: there are many and wide dust generation points in processes such as sintering, coking, and steel rolling. The dust emission rate is high in processes such as raw material transfer and belt transportation. Existing dust removal systems have a wide coverage area, but the compliance rate of workshop environment is insufficient. The equipment coordination is insufficient: the matching degree between dust removal fans and dust sources is low, resulting in wasted air volume or insufficient collection efficiency, leading to high energy consumption and treatment costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a mobile semi-sealed collection hood with an air curtain, so as to solve the problems in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A mobile semi-sealed dust collection hood with an air curtain includes two parallel tracks set on the workshop floor. A hood body that can move along the tracks is mounted on both sides via walking machines. The top of the hood body is provided with a dust extraction port for extracting dust. The dust extraction port is connected to an exhaust fan for providing suction power through a pipe. Air curtain nozzles for preventing dust diffusion are provided at the openings at both the front and rear ends of the hood body. The air curtain is connected to an external air compressor through a pipe.

[0006] To further optimize the technical solution, the walking machine includes several wheels that can move along the track at the bottom of the walking machine and a motor for driving the wheels to move. A sprocket is provided on the axle of one wheel, and the sprocket is connected to the motor shaft of the motor by a chain.

[0007] To further optimize the technical solution, the side end of the cover is provided with a maintenance door for inspecting and repairing the collection cover.

[0008] To further optimize the technical solution, the connection between the top of the cover and the side wall is a 45° inclined structure.

[0009] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0010] This utility model provides a mobile semi-sealed collection hood with an air curtain. By combining the semi-sealed collection hood and the air curtain, the fan and the dust source can be linked in real time, enabling precise control of the dust source, reducing the dust diffusion range, and achieving the best effect with the minimum air volume. This reduces the frequency of fan use and improves fan energy efficiency. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model;

[0012] Figure 2 This is a side view of the present invention.

[0013] The components include: 1. track, 2. cover, 3. walking machine, 4. dust suction port, 5. air curtain blowing port, 6. inspection door, 7. sprocket, 8. motor, and 9. chain. Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] A mobile semi-sealed trapping hood with an air curtain, combined with Figures 1 to 2 As shown, it includes two parallel tracks 1 set on the workshop floor, a cover 2 set on the track 1, which enables the cover 2 to move along the track 1, and a dust removal suction port 4 set on the top of the cover 2. The dust removal suction port 4 is connected to an exhaust fan through a pipe to provide suction to remove dust.

[0016] Air curtain nozzles 5 are installed at the openings at both the front and rear ends of the enclosure 2. The air curtain nozzles 5 are connected to an external air compressor through pipes. The air compressor blows air through the air curtain nozzles at both ends of the enclosure to form an air curtain, which can effectively prevent dust from drifting out of the enclosure, reduce the ventilation volume inside the enclosure, improve the dust collection effect, thereby optimizing the air volume and achieving precise control of the dust source.

[0017] The cover 2 is mounted on a track via two walking machines 3 on both sides. The walking machine includes wheels and a motor 8. There are several wheels, which are located at the bottom of the walking machine 3. The motor 8 is used to drive the wheels to move along the track. A sprocket 7 is mounted on the axle of one of the wheels. The motor shaft of the motor 8 is connected to the sprocket 7 via a chain 9, which is used to drive the sprocket to rotate. The rotation of the sprocket drives the wheel to rotate, thereby realizing the movement of the cover on the track.

[0018] The side end of the cover 2 is provided with an inspection door 6 for maintenance of the inside of the cover.

[0019] The connection between the top and side wall of the cover 2 is a 45° inclined structure to avoid dead angles in the wind direction and improve the efficiency of dust extraction.

[0020] In this invention, when extracting dust in a workshop, the operator manually controls a walking machine to move the hood to the desired extraction position. Once in place, an air compressor blows air through the air curtain nozzles onto the opening of the hood, while a blower simultaneously extracts the dust from inside the hood. The air curtain nozzles isolate the dust inside the hood from the air outside, preventing air from flowing out of the hood and thus preventing dust diffusion, thereby improving the efficiency of dust extraction.
