Description

Technical Field

[0001] This utility model belongs to the field of flue gas circulation technology for tobacco curing barns, and specifically relates to a flue gas circulation guide plate for tobacco curing barns. Background Technology

[0002] During the tobacco curing process, the tobacco curing barn needs to continuously dehumidify in order to ensure the quality of the tobacco leaves. Traditional dehumidification outlets mostly use direct discharge, which results in a large amount of heat loss due to the direct discharge of high-temperature flue gas. In addition, the uneven distribution of temperature and humidity in the curing barn is easily caused by airflow turbulence, which affects the color and aroma composition of the tobacco leaves.

[0003] Existing airflow guiding devices are mostly fixed baffles. Although they can partially guide airflow, they have significant drawbacks. Not only can the fixed angle not adapt to the temperature and humidity control requirements of different baking stages, resulting in fluctuations in dehumidification efficiency, but the high temperature and high humidity environment can also cause the airflow guiding plate to oxidize and deform, reducing structural stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a flue gas circulation guide plate for tobacco curing barns to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flue gas circulation guide plate for a tobacco curing barn, comprising an arc-shaped guide plate body, a fixed bracket, and an angle adjustment mechanism. The arc-shaped guide plate body has an arc-shaped cross-section, with the concave surface being the guide surface and the convex surface being the back plate surface. The fixed bracket is symmetrically fixed to the left and right walls inside the exhaust port of the tobacco curing barn. The fixed bracket is an L-shaped angle steel structure, and the fixed bracket includes a vertical fixed side and a horizontal supporting side. The angle adjustment mechanism connects the back plate surface of the arc-shaped guide plate body to the lower end of the vertical fixed side of the fixed bracket.

[0006] Preferably, the vertical fixing edge of the fixed bracket is fastened to the inner wall of the drying oven's vent by bolts.

[0007] Preferably, the angle adjustment mechanism includes an adjustment screw, an adjustment nut, and an adjustment seat. The adjustment seat is welded to the back plate surface of the arc-shaped guide plate body, and a locking nut is installed on the top of the adjustment nut.

[0008] Preferably, the back plate of the arc-shaped guide plate is welded with cross-shaped reinforcing ribs, which are fully welded to the back of the plate.

[0009] Preferably, the back surface of the arc-shaped guide plate is coated with a high-temperature resistant and antioxidant coating.

[0010] Preferably, the lower end of the arc-shaped guide plate is provided with an oil slick.

[0011] Compared with existing technologies, this utility model provides a flue gas circulation guide plate for tobacco curing barns, which has the following beneficial effects: The adjustable guide plate allows for adjustable inclination angle to match the needs of each stage of curing. During the yellowing stage, the inclination angle is increased to enhance the return of humid heat, while during the drying stage, the inclination angle is decreased to accelerate dehumidification. The cross-shaped reinforcing ribs on the back plate are fully welded and fixed, solving the problem of high-temperature deformation. Combined with a high-temperature resistant and anti-oxidation coating, the frequency of maintenance is reduced. The arc-shaped guide surface guides the flue gas from the dehumidification port to return to the center of the curing barn. The L-shaped angle steel bracket is fastened to the side wall of the dehumidification port with bolts, which combines support stability and convenient installation. It is suitable for the renovation of existing curing barns, realizing the value of energy saving, efficiency improvement and cost reduction. Attached Figure Description

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

[0020] Please see Figure 1This utility model provides a technical solution: 1. A flue gas circulation guide plate for a tobacco curing barn, comprising an arc-shaped guide plate body 1, a fixed bracket 2, and an angle adjustment mechanism 3. The arc-shaped guide plate body 1 has an arc-shaped cross-section, with the concave surface being the guide surface 101 and the convex surface being the back plate surface 102. The fixed bracket 2 is symmetrically fixed to the left and right walls inside the exhaust port of the tobacco curing barn. The fixed bracket 2 is an L-shaped angle steel structure. The fixed bracket 2 includes a vertical fixed side 201 and a horizontal support side 202. The angle adjustment mechanism 3 connects the back plate surface 102 of the arc-shaped guide plate body 1 to the lower end of the vertical fixed side 201 of the fixed bracket 2.

[0021] In this invention, preferably, the vertical fixed edge 201 of the fixed bracket 2 is fastened to the inner wall of the drying chamber exhaust port by bolts. The angle adjustment mechanism 3 includes an adjusting screw 301, an adjusting nut 302, and an adjusting seat 303. The adjusting seat 303 is welded to the back plate surface 102 of the arc-shaped guide plate body 1. A locking nut 304 is installed on the top of the adjusting nut 302. The back plate surface 102 of the arc-shaped guide plate body 1 is welded with cross-shaped reinforcing ribs, which are fully welded to the back of the plate body. The back plate surface 102 of the arc-shaped guide plate body 1 is coated with a high-temperature resistant and anti-oxidation coating. A smoke oil tank 4 is provided at the lower end of the arc-shaped guide plate body 1. The smoke oil generated by the smoke blockage falls into the smoke oil tank 4, which can be disassembled and cleaned.

[0022] The working principle and usage process of this utility model are as follows: During use, confirm that the vertical fixing edge 201 of the fixed bracket 2 is not deformed. Place two sets of L-shaped angle steel fixed brackets 2 symmetrically on the inner wall of the tobacco curing barn's humidification outlet. Securely connect them to the barn wall using bolts through the holes in the vertical fixing edge 201, ensuring the horizontal support edge 202 is horizontal. Hoist the arc-shaped guide plate 1 onto the horizontal support edge 202 of the fixed bracket 2, aligning the adjustment seat 303 welded to the back plate 102 with the angle adjustment mechanism 3. Then, screw one end of the adjustment screw 301 into the screw at the lower end of the vertical fixing edge 201 of the fixed bracket 2. The other end passes through the through hole of the adjusting seat 303 and is pre-fixed with the adjusting nut 302. After the baking starts, observe the flue gas flow. When the guide angle needs to be adjusted, first loosen the adjusting nut 302, rotate the adjusting screw 301 to drive the arc-shaped guide plate 1 to rotate around the axis of the horizontal support side 202. After confirming the angle, tighten the adjusting nut 302 to prevent displacement. After each batch of baking is completed, check whether the welding point of the cross reinforcing rib on the back plate 102 is cracked, remove the dust accumulated on the guide surface 101, and check the wear of the thread of the adjusting screw 301 during quarterly maintenance. Reapply the high-temperature resistant coating that has fallen off the back plate 102.
