[0041] Please refer to the following: Figures 1 to 4 The side-suction gas collection device provided by this utility model will now be described. The side-suction gas collection device includes a support 20, a gas collection component 30, and a cantilever beam 40. The support 20 is used to install to the side wall of the steel frame 10 of the factory building; the gas collection component 30 is installed on the support 20 and includes a gas collection pipe 31 and a gas collection hood 32 communicating with the gas collection pipe 31. The opening of the gas collection hood 32 is away from the installation side of the support 20; the cantilever beam 40 is fixedly connected to the bottom of the support 20.

[0042] Compared with the prior art, the side-suction gas collection device provided in this embodiment has the following advantages: the support 20 and the cantilever beam 40 are respectively installed on one side wall of the steel frame 10 of the factory building (same as the "workshop" mentioned above), and the gas collection component 30 is fixed on the support 20. Since the support 20 needs to ensure that the gas collection hood 32 is tilted towards the space inside the factory building, the support 20 is installed at an angle, and the cantilever beam 40 is fixed at the bottom of the support 20, which can ensure the stability of the gas collection component 30 after installation. By fixing the gas collection component 30 to one side wall of the factory building through the support 20 and the cantilever beam 40, it is not necessary to occupy the space of the workshop floor, so that vehicles can pass smoothly and there is no need to excavate the ground, thus reducing the engineering cost.

[0043] In some embodiments, a specific implementation of the above-described support 20 may employ the following method: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The support frame 20 includes a tie rod 21 and a fixed frame 22. One end of the tie rod 21 is connected to the steel frame 10 of the factory building. The fixed frame 22 is fixed between the other end of the tie rod 21 and the cantilever beam 40. The fixed frame 22 is fixedly connected to the opening end of the gas collection hood 32 and conforms to the outer contour of the opening on the gas collection hood 32. The opposite sides of the fixed frame 22 are fixedly connected to the tie rod 21 and the cantilever beam 40 respectively, ensuring the installation stability of the fixed frame 22. Since the opening of the gas collection hood 32 is tilted towards the interior space of the factory building, the fixed frame 22 has an angle relative to the horizontal plane. By connecting the tie rod 21 and the cantilever beam 40 to the opposite sides of the fixed frame 22 respectively, the tilting state of the fixed frame 22 can be stabilized, thereby ensuring the tilting setting of the gas collection hood 32 and improving the gas collection efficiency.

[0044] The bracket 20 in this embodiment has a simple structure, is easy to install, and has a low cost.

[0045] In some embodiments, an improved implementation of the above-described support 20 may employ, as follows: Figures 1 to 3 The structure shown. See also Figures 1 to 3 The tie rod 21 is rotatably connected to the steel frame 10 of the factory building. The cantilever beam 40 is provided with a telescopic part, and the fixed frame 22 is rotatably connected to the telescopic part.

[0046] By rotating the lever 21, the angle between the fixed frame 22 and the horizontal plane can be adjusted, thereby changing the opening orientation of the gas collection hood 32 and making it closer to the flue gas generation area, thus improving the gas collection efficiency. When the lever 21 is rotated for adjustment, the telescopic part extends and retracts according to the position change of the fixed frame 22, making it convenient to adjust the gas collection hood 32 and more flexible to use.

[0047] It should be noted that when the pull rod 21 rotates, the angle of the fixed frame 22 changes, and the height also changes to a certain extent. In order to ensure the connection with the fixed frame 22, the telescopic part can not only extend and retract, but also has multiple mounting holes distributed in the vertical direction. The fixed frame 22 is connected to a rotating shaft, which is fixed to the corresponding mounting hole through a threaded connector. Therefore, when the pull rod 21 rotates, the mounting hole corresponding to the rotating shaft installed on the fixed frame 22 on the telescopic part also changes.

[0048] In some embodiments, a specific implementation of the cantilever beam 40 may adopt the following approach: Figure 3 The structure shown. See also Figure 3 The cantilever beam 40 includes a fixed beam body 41 and a telescopic beam body 42. The fixed beam body 41 is horizontally fixed to the steel frame 10 of the factory building; the telescopic beam body 42 is slidably connected to the fixed beam body 41, forming a telescopic section. By sliding and adjusting the telescopic beam body 42 on the fixed beam body 41, it can adapt to the positional changes of the fixed frame 22 as the tie rod 21 rotates, making adjustment convenient.

[0049] It is easy to imagine that after the telescopic beam 42 is adjusted, it needs to be fixed. Multiple through holes can be set on the telescopic beam 42 and the fixed beam 41 along the telescopic direction. After the telescopic beam 42 is adjusted, a pin can be inserted into the corresponding through hole to fix the telescopic beam 42.

[0050] It should be noted that the telescopic beam 42 is an L-shaped beam. The horizontal section of the telescopic beam 42 is inserted into the fixed beam 41 and slides with the fixed beam 41. The aforementioned multiple mounting holes are located on the vertical section of the telescopic beam 42.

[0051] In some embodiments, a specific implementation of the fixed border 22 described above can be as follows: Figure 4 The structure shown. See also Figure 4 The fixed frame 22 includes an upper beam 221, a lower beam 222, and two side beams 223. The upper beam 221 is connected to the tie rod 21; the lower beam 222 is connected to the cantilever beam 40; and the two side beams 223 are respectively connected between the upper beam 221 and the lower beam 222. The upper beam 221 and the lower beam 222 are parallel, and the two side beams 223 are parallel. The upper beam 221, the lower beam 222, and the two side beams 223 enclose a rectangular fixed frame 22, which can be installed and fixed at the opening of the gas collection hood 32. The structure is simple and easy to install.

[0052] Optionally, the upper beam 221, lower beam 222, and side beam 223 can all be I-beams, and they can be connected to each other by welding. Similarly, the fixed frame 22 and the tie rod 21 can also be connected by welding.

[0053] The openings of the fixed frame 22 and the gas collection hood 32 can be connected by adhesive.

[0054] In some embodiments, an improved implementation of the above-described gas collection assembly 30 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The gas collection assembly 30 also includes a reinforcing frame 33 fitted around the outer periphery of the gas collection hood 32, and the reinforcing frame 33 is fixedly connected to the fixed frame 22. It is easy to see that in order to achieve gas collection, a fan needs to be configured on the gas collection pipe 31 to perform the ventilation function. During the ventilation process, the gas collection hood 32 will sway due to the airflow. By setting up the reinforcing frame 33 and fixing the reinforcing frame to the fixed frame 22, the installation stability of the gas collection hood 32 can be improved, and the probability of damage to the gas collection hood 32 can be reduced, thus extending the service life of the gas collection hood 32.

[0055] Specifically, the reinforcing frame 33 includes multiple collars 331 and connecting rods 332. The multiple collars 331 are spaced apart along the axial direction of the gas collection hood 32. The connecting rods 332 are connected between the multiple collars 331 and fixed to the fixed frame 22. The gas collection hood 32 has a conical structure, and the outer diameters of the multiple collars 331 are different to fit different positions on the outer circumference of the gas collection hood 32. After the multiple collars 331 are installed, the connecting rods 332 are connected to each collar 331, and finally fixed to the fixed frame 22, thereby reinforcing the gas collection hood 32.

[0056] In some embodiments, an improved implementation of the above-described reinforcement frame 33 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2The collar 331 has multiple positioning holes, and the connecting rod 332 has positioning pins 333 that engage with the positioning holes. After the multiple collars 331 are fitted onto the outer periphery of the gas collection hood 32, the positioning pins 333 on the connecting rod 332 are aligned with the positioning holes on the collars 331 and then installed, thus completing the assembly of the reinforcement frame 33. The operation is simple, and the installation position of the connecting rod 332 can be positioned through the positioning holes, improving assembly efficiency.

[0057] In some embodiments, an improved implementation of the above-described gas collection assembly 30 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The gas collection assembly 30 also includes an electrically controlled valve 34 located between the gas collection pipe 31 and the gas collection hood 32. The electrically controlled valve 34 allows the gas collection assembly 30 to be closed when it is not in use. The electrically controlled valve 34 can be remotely or directly controlled, making it flexible in use.

[0058] In some embodiments, an improved implementation of the above-described gas collection assembly 30 may employ, as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 A corrugated pipe 35 connects the gas collection hood 32 and the gas collection pipe 31. The corrugated pipe 35 is flexible and has a certain degree of expansion and contraction. Therefore, when rotating to adjust the opening tilt angle of the gas collection hood 32, or when installing the gas collection assembly 30, the gas collection hood 32 can be easily moved or pulled to meet the installation needs of different scenarios.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
