Technical Field

[0001] The utility model mainly relates to the technical field of ventilation and cooling, in particular to a cooling and ventilation device for an alloy steel refining workshop. Background Art

[0002] The alloy steel refining workshop is a crucial step in the steel production process, primarily responsible for further refining the initially smelted alloy steel to improve its quality and performance. During the manufacturing process, the workshop environment is subject to significant amounts of hot air. This is typically achieved by installing air inlets or fans in the workshop side walls to bring in fresh air. These inlets or fans should be used in conjunction with rooftop fans to ensure air circulation within the workshop.

[0003] For the sake of economy and practicality, fan exhaust is currently a commonly used device. During the use of this type of equipment, electricity is consumed, and as the ventilation volume and number increase, energy consumption will also increase accordingly. Therefore, when designing a ventilation system, energy-saving measures must be considered while ensuring ventilation and cooling effects. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example

[0026] like Figure 1 、 2 As shown in Figure 3, it includes a support frame 10 and an exhaust fan 20. The support frame 10 includes a first cross bar 11 at the top of the inner wall of the workshop wall, a cross-shaped support bar 12 at the bottom of the first cross bar 11, and a second cross bar 13 at the bottom of the cross-shaped support bar 12; the cross-shaped support bar 12 is composed of four connecting members 121 and ten connecting square tubes 122 on the side walls of the connecting member 121. The connecting member 121 is cross-shaped, and the top, bottom and both ends of the connecting member 121 are connected to support rods 123. The connecting support rods 123 are slidably connected to the inner wall of the connecting square tube 122. The cross-section of the connecting support rods 123 is square. The outer wall of the rectangular frame 21 is slidably connected to the inner wall of the cross-shaped support rod 12, and the limiting side plate 22 is connected to the cross-shaped support rod 12 by screws.

[0027] It should be noted that, in this embodiment, the four connecting members 121 serve as the connection base, and the ten connecting square tubes 122 are respectively sleeved on the top and bottom of the connecting members 121 and the connecting rods 123 at both ends, naturally forming a well-shaped support rod 12;

[0028] The crisscross support rod 12 is fixed to the wall at the ventilation opening a of the workshop by welding the first cross bar 11 and the second cross bar 13 at the top and bottom thereof. Finally, the exhaust fan 20 is embedded in the center position of the crisscross support rod 12, and the limiting side plate 22 is fixed to the crisscross support rod 12 with screws for use.

[0029] like Figure 1 、 4 As shown in FIG. 5 , the exhaust fan 20 passes through one side of the well-shaped support rod 12 and is located at the center of the well-shaped support rod 12 .

[0030] It should be noted that, in this embodiment, when the exhaust fan 20 starts to rotate, the wind flow and wind pressure near the exhaust fan 20 change, and the hot air inside the workshop flows out to the outside of the workshop under the guidance of the exhaust fan 20. Among them, the well-shaped support rod 12 increases the space for air flow. When the exhaust fan 20 exhausts air, the air around the exhaust fan 20 is also affected and driven to flow out to the outside of the workshop.

[0031] like Figure 1 、 2 As shown in Figure 3, the first cross bar 11 and the second cross bar 13 have the same structure and are symmetrically arranged. A side panel 111 is installed on one side of the first cross bar 11, a rectangular frame 21 is installed on the outer wall of the exhaust fan 20, and the top and bottom limiting side panels 22 on one side of the rectangular frame 21 are arranged in combination with the exhaust fan 20 at the top window of the workshop wall.

[0032] It should be noted that, in this embodiment, the mounting side plate 111 is used to fix the entire support frame 10 at the vent, and the limiting side plate 22 is used to be embedded in the center position of the cross-shaped support rod 12.

[0033] The working principle of this utility model is:

[0034] In terms of installation, the four connecting pieces 121 are used as the connection base, and the ten connecting square tubes 122 are respectively placed on the top and bottom of the connecting pieces 121 and the connecting rods 123 at both ends, naturally forming a well-shaped support rod 12;

[0035] The well-shaped support rod 12 is fixed to the wall at the ventilation opening a of the workshop by welding the first cross bar 11 and the second cross bar 13 at the top and bottom thereof. Finally, the exhaust fan 20 is embedded in the center position of the well-shaped support rod 12, and the limiting side plate 22 is fixed to the well-shaped support rod 12 with screws for use;

[0036] During the operation of the entire device, Figure 4 As shown, when the exhaust fan 20 starts to rotate, the wind flow and wind pressure near the exhaust fan 20 change, and the hot air inside the workshop flows out to the outside of the workshop under the guidance of the exhaust fan 20. Among them, the well-shaped support rod 12 increases the space for air flow. While the exhaust fan 20 is exhausting, the air around the exhaust fan 20 is also affected and driven to flow out to the outside of the workshop, thereby increasing the efficiency of cooling and ventilation.

[0037] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
