Description

Technical Field

[0001] This utility model relates to the field of flue gas capture technology, specifically to an adjustable guide plate type flue gas capture hood. Background Technology

[0002] Industrial production processes generate flue gas containing dust and harmful gases. Direct emission of such gas will pollute the atmosphere and harm human health. Since some pollutants are attached to dust, they need to be captured before treatment. Flue gas capture is the primary step in pollution control. Specific equipment is needed to gather the diffused flue gas and guide it into the purification system. The core equipment is the flue gas capture hood. Traditional capture hoods often have low capture efficiency due to the disordered flow of flue gas. To address this, a guide vane is installed inside or at the hood opening to guide the flue gas to flow along a preset path, reducing escape and laying the foundation for subsequent purification. This becomes a key structure for improving the capture effect.

[0003] However, existing flue gas capture hoods are not convenient to adjust the tilt angle of the guide plate during use. When industrial production conditions change, the flue gas velocity and diffusion direction will change. At this time, the guide plate is difficult to gather the flue gas in time, causing a large amount of flue gas to escape from the gaps or openings of the hood, which will pollute the workshop environment and increase the difficulty of subsequent cleaning. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an adjustable guide plate type flue gas capture hood to solve the problem that existing flue gas capture hoods are not convenient to adjust the tilt angle of the guide plate during use. When industrial production conditions change, the flue gas velocity and diffusion direction will change. At this time, the guide plate is difficult to gather the flue gas in time, causing a large amount of flue gas to escape from the gaps or openings of the hood, which will pollute the workshop environment and increase the difficulty of subsequent cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adjustable baffle-type flue gas capture hood includes a hood body and a ventilation pipe connected to the top of the hood body. It further includes: an adjustment section located on the front side of the hood body; two disassembly sections, both installed inside the hood body; the adjustment section includes two rotating components, both installed on the front side of the hood body; and a power component located on the front side of the hood body. Each rotating component includes a rotating shaft rotatably connected to the inner wall of the hood body. A first bracket is fixedly connected to the outer wall of the rotating shaft, and a second bracket is slidably connected to the inner wall of the first bracket. A spring is fixedly connected to the top inner wall of the second bracket, and the bottom of the spring is fixedly connected to the first bracket. The two rotating components are mirror images of each other, and the rotation of the rotating shaft drives the first bracket, the second bracket, and the spring to move in coordination. The mirror image arrangement of the two components provides basic support and elastic buffering for adjusting the baffle angle.

[0006] Preferably, the disassembly / assembly part includes a positioning component disposed inside the cover; and a fixing component, wherein a plurality of fixing components are disposed inside the cover and are arranged in a linear array.

[0007] Preferably, the power assembly includes two connecting blocks fixedly connected to the front side of the cover, two limiting rods fixedly connected between the two connecting blocks, and a power component disposed between the two limiting rods. The two connecting blocks and the two limiting rods are mirror images of each other. The power component includes a slider slidably connected to the outer wall of the two limiting rods. The left and right sides of the slider are respectively hinged to the two brackets. An electric telescopic rod is fixedly connected to the inner wall of the bottom connecting block. The output shaft of the electric telescopic rod is fixedly connected to the slider. The electric telescopic rod drives the slider to slide along the limiting rods, thereby driving the brackets to move, providing power for the operation of the rotating assembly, and realizing the automated control of the guide plate adjustment.

[0008] Preferably, the positioning component includes a connecting plate fixedly connected to the outer wall of the rotating shaft. The outer wall of the connecting plate is provided with a guide plate. The guide plate contains a plurality of positioning elements arranged in a linear array. Each positioning element includes a positioning hole one opened in the inner wall of the connecting plate and a positioning hole two opened at the bottom of the guide plate. The positioning hole one penetrates the connecting plate. The diameter of the positioning hole one is the same as that of the positioning hole two, and both are adapted to the plug. By aligning the positioning hole one on the connecting plate with the positioning hole two on the guide plate and inserting the plug, the positioning of the guide plate and the rotating shaft is achieved.

[0009] Preferably, the fixing component includes a plug disposed within the guide plate. A magnet is fixedly connected to the inner wall of the plug, and a magnet is fixedly connected to the inner wall of the guide plate. The magnetic poles of the magnet and the magnet are opposite on the side that are close to each other. The magnet in the plug and the magnet in the guide plate attract each other, which enhances the fixing effect of the plug on the guide plate and facilitates the disassembly and assembly of the guide plate.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. By setting up the adjustment section, the power component in the power assembly is activated, which drives the slider to slide along the limit rod. The movement of the slider will drive the second bracket, which in turn causes the first bracket to rotate around the pivot. The rotation of the pivot drives the guide plate to rotate through the connecting plate. At the same time, the slider will squeeze the spring during the sliding process. The spring generates elastic force to assist the second bracket and the first bracket in unfolding, thereby completing the angle adjustment of the guide plate. The tilt angle of the guide plate can be adjusted when needed. When the flow of flue gas changes, the angle can be changed in time to prevent flue gas from escaping from the gaps or openings of the cover, prevent flue gas from polluting the working environment, and reduce the difficulty of subsequent cleaning. 2. By setting up a disassembly and assembly section, when cleaning the air deflector, use force to pull the plug out from positioning hole two and slide it out from positioning hole one. Magnet one moves away from magnet two, and the air deflector can be removed for cleaning after it is no longer restricted. After cleaning, insert the air deflector back into the connecting plate, then insert the plug into positioning hole two and pass it through positioning hole one. Use the magnetic force of magnet one and magnet two to fix the plug, thus completing the air deflector installation. When cleaning is needed, the air deflector can be removed for cleaning. Moreover, it is not only simple to operate, but also has no excessive gaps in its structure, which can reduce the difficulty of cleaning the air deflector.
