Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ventilation and air exchange devices, specifically a ventilation and air exchange device for a dehydration workshop. Background Technology
[0002] Ventilation and air exchange devices utilize the axial thrust generated when the impeller rotates to drive air to flow along the axial direction, achieving large-area ventilation and air exchange. They have a large air volume and low air pressure, making them suitable for places that require a large amount of ventilation but do not have high requirements for air pressure, such as dehydration workshops. They can be installed on walls or roofs and can quickly remove hot and humid air and odors from the workshop.
[0003] The existing ventilation system pushes air along the axial direction, and the ventilation vents are relatively small. This results in the ventilation vents in the dehydration workshop being too small, causing the ventilation speed in the dehydration workshop to be too slow. The axial thrust noise of the ventilation system is also too loud, resulting in excessive noise in the dehydration workshop and affecting the hearing of the staff. Utility Model Content
[0004] The purpose of this invention is to provide a ventilation and air exchange device for a dehydration workshop to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A ventilation and air exchange device for a dehydration workshop includes a flange, an axial flow fan shroud, an impeller mounting bracket, and a mounting assembly. The axial flow fan shroud is mounted on a fixed portion of the flange, and the impeller mounting bracket is installed at a welded joint on the axial flow fan shroud. The mounting assembly also includes a fixed portion of the flange and further includes...
[0007] A dual-ventilation axial flow assembly is mounted on the flange;
[0008] Noise reduction components are mounted on the axial flow fan shroud;
[0009] The flange has a threaded retaining bolt at the snap fastener, a protective railing at the welded joint on the impeller mounting bracket, an axial disc at the mounting point on the protective railing, and a foldable wing-type ventilation hood at the folding point on the flange.
[0010] The ventilation and air exchange device for the dehydration workshop as described above: the impeller mounting bracket and the guardrail are fixedly installed by an axial disc.
[0011] The ventilation and air exchange device for the dehydration workshop as described above: the flange and the axial flow fan cover are fixedly installed on the wall of the dehydration workshop by fixing bolts.
[0012] The ventilation and air exchange device for the dehydration workshop as described above: the dual ventilation axial flow assembly includes a ventilation hood fixed on the flange, a ventilation axial flow fan fixedly installed inside the ventilation hood, an internal hole for ventilation opening on the ventilation hood, and bolt covers threaded around the ventilation hood.
[0013] The ventilation and air exchange device for the dehydration workshop as described above: the ventilation hood and the plug cover are threadedly supported on the foldable wing-type ventilation hood.
[0014] The ventilation and air exchange device for the dehydration workshop as described above: the noise reduction component includes a threaded cover fixedly connected to the inner wall of the axial flow fan cover, and a vibration damping plate sleeve is provided at the mounting point on the threaded cover.
[0015] The ventilation and air exchange device for the dehydration workshop as described above: the vibration damping plate sleeve and the threaded cover are installed at the mounting points on the axial flow fan cover and the impeller mounting bracket.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the axial flow fan cover and the ventilation axial flow fan are assembled as a whole on the ventilation and air exchange device. The ventilation and air exchange device drives the ventilation axial flow fan and the axial flow fan cover. By using the axial thrust generated when the impeller rotates, the air is pushed to flow along the axial direction to achieve large-area ventilation and air exchange. The user can then fold the foldable wing-type ventilation cover onto the flange, so that the ventilation axial flow fan is exposed in the dehydration workshop. This not only expands the ventilation space of the ventilation and air exchange device, but the ventilation cover and the built-in hole can also expand the ventilation and air exchange vents, thus expanding the ventilation and air exchange vents in the dehydration workshop. The axial flow fan cover and the ventilation axial flow fan improve the ventilation speed in the dehydration workshop.
[0017] When the axial flow fan cover and the ventilation axial flow fan can use the same principle for ventilation, the installation of vibration damping plates around the outside of the axial flow fan cover can isolate noise from the axial flow fan cover and the ventilation axial flow fan. The vibration damping plates are made of butyl rubber and aluminum foil, which have good damping performance and can effectively suppress the vibration of the axial flow fan cover and the ventilation axial flow fan, reduce the noise generated by vibration, and also play a certain role in sound insulation, reduce the axial thrust noise of the ventilation device, prevent excessive noise in the dehydration workshop, and prevent excessive noise from damaging the hearing of the staff.

[0026] Please see Figures 1-4 A ventilation device for a dehydration workshop is proposed, comprising a flange 1, an axial flow fan cover 3, an impeller mounting bracket 4, and mounting components.
[0027] An axial flow fan cover 3 is installed at the fixing point on flange 1. An impeller mounting bracket 4 is provided at the welding point on the axial flow fan cover 3. A flange 1 is provided at the fixing point on the mounting assembly. A dual ventilation axial flow assembly is installed on flange 1. A noise reduction assembly is provided on the axial flow fan cover 3.
[0028] The impeller mounting bracket 4 is threaded onto the axial flow fan cover 3. The axial flow fan cover 3 and the impeller mounting bracket 4 are installed through the flange 1. The flange 1 thread passes through the wall of the dehydration workshop and is installed through a gap in the wall of the dehydration workshop.
[0029] Among them, the flange 1 has a threaded fastener 2 through the snap fastener, the impeller mounting bracket 4 has a protective railing 5 at the welded part, the protective railing 5 has an axial disc 6 at the mounting part, and the flange 1 has a foldable wing-type ventilation hood 7 at the folding part.
[0030] In this embodiment, after the flange 1 is threaded through the wall of the dehydration workshop, the fixing bolt 2 is threaded through the flange 1, so that the flange 1 is fastened to the wall of the dehydration workshop. The axial flow fan cover 3 and the impeller mounting bracket 4 are installed as a whole at the gap in the wall of the dehydration workshop. The guardrail 5 and the axial disc 6 are installed inside the axial flow fan cover 3. The ventilation and air exchange device uses the axial thrust generated by the rotation of the impeller through the axial flow fan cover 3 to push the air to flow along the axial direction, so as to achieve large-area ventilation and air exchange. Then, the foldable wing-type ventilation cover 7 is installed on the flange 1, and can be folded and installed on the axial flow fan cover 3 and the impeller mounting bracket 4.
[0031] Preferably, the impeller mounting bracket 4 and the guardrail 5 are fixedly installed by the axial disc 6. The ventilation and air exchange device is installed as a whole at the gap in the wall of the dehydration workshop by the axial flow fan cover 3 and the impeller mounting bracket 4. The guardrail 5 and the axial disc 6 are installed on the axial flow fan cover 3 for protection. The ventilation and air exchange device pushes the air to flow along the axial direction and passes through the axial flow fan cover 3 for ventilation.
[0032] Preferably, flange 1 and axial fan cover 3 are fixedly installed on the wall of the dehydration workshop by fixing bolt 2. Axial fan cover 3 and impeller mounting bracket 4 are threadedly fastened to the wall of the dehydration workshop by flange 1 and fixing bolt 2. The air in the dehydration workshop is pushed to flow axially by the ventilation and air exchange device.
[0033] Please refer to Figure 2 and Figure 3 In this embodiment, the dual-ventilation axial flow assembly includes a ventilation hood 11 fixed on the flange 1, a ventilation axial flow fan 10 fixedly installed inside the ventilation hood 11, an internal hole 9 provided for the ventilation opening on the ventilation hood 11, and bolt covers 8 threadedly connected around the ventilation hood 11.
[0034] The ventilation hood 11 is installed on the axial flow fan hood 3 by means of the flange 1. The flange 1 can be fastened to the connection between the ventilation hood 11 and the axial flow fan hood 3, so that the ventilation axial flow fan 10 is fixedly installed inside the ventilation hood 11. The ventilation hood 11 allows air exchange through the built-in hole 9.
[0035] Preferably, the ventilation hood 11 and the bolt cover 8 are threadedly fastened and supported on the foldable wing-type ventilation hood 7. The axial flow fan 10 is installed on the axial flow fan cover 3 through the ventilation hood 11. The axial flow fan cover 3 and the axial flow fan 10 are assembled as a whole on the ventilation and air exchange device. The ventilation and air exchange device drives the axial flow fan 10 and the axial flow fan cover 3. By utilizing the axial thrust generated when the impeller rotates, the air is pushed to flow axially, achieving large-area ventilation and air exchange. The user then folds the foldable wing-type ventilation hood 7 onto the flange 1, exposing the axial flow fan 10 to the dehydration workshop. This not only expands the ventilation space of the ventilation and air exchange device, but the ventilation hood 11 and the built-in hole 9 can also expand the ventilation and air exchange vents, thus expanding the ventilation and air exchange vents in the dehydration workshop. The axial flow fan cover 3 and the axial flow fan 10 increase the ventilation speed in the dehydration workshop. The axial flow fan 10 can also use the axial thrust generated when the impeller rotates to push the air to flow axially, achieving the ventilation and air exchange effect.
[0036] Please refer to Figure 1 and Figure 4 In this embodiment, the noise reduction component includes a threaded cover 13 fixedly connected to the inner wall of the axial flow fan cover 3, and a vibration damping plate sleeve 12 is provided at the mounting point on the threaded cover 13.
[0037] The vibration damping plate sleeve 12 is installed around the outside of the axial flow fan cover 3. The axial flow fan cover 3 and the vibration damping plate sleeve 12 are installed inside the axial flow fan cover 3 through the threaded cover 13. The axial flow fan cover 3 and the ventilation axial flow fan 10 can use the same principle for ventilation.
[0038] Preferably, the vibration damping sleeve 12 and the threaded cover 13 are installed at the mounting points on the axial flow fan cover 3 and the impeller mounting bracket 4. When the axial flow fan cover 3 and the ventilation axial flow fan 10 can be ventilated using the same principle, the vibration damping sleeve 12, installed around the outside of the axial flow fan cover 3, can isolate the axial flow fan cover 3 and the ventilation axial flow fan 10 from noise. The vibration damping sleeve 12 is made of butyl rubber and aluminum foil, which has good damping performance and can effectively suppress the vibration of the axial flow fan cover 3 and the ventilation axial flow fan 10, reduce the noise generated by vibration, and also play a certain role in sound insulation, reducing the axial thrust noise of the ventilation device, preventing excessive noise in the dehydration workshop, and preventing excessive noise from damaging the hearing of the staff.
[0039] As can be seen from the above, during use, the fixing bolt 2 is threaded through the flange 1, and the flange 1 is then fastened to the wall of the dehydration workshop. The axial flow fan cover 3 and the impeller mounting bracket 4 are installed as a whole at the opening in the wall of the dehydration workshop. The guardrail 5 and the axial disc 6 are installed inside the axial flow fan cover 3. The ventilation device uses the axial thrust generated by the rotation of the impeller through the axial flow fan cover 3 to push the air to flow axially. The vibration damping plate sleeve 12 is installed around the outside of the axial flow fan cover 3, which can isolate the noise of the axial flow fan cover 3 and the ventilation axial flow fan 10. The vibration damping plate sleeve 12 is made of butyl rubber and aluminum foil, which has good damping performance and can effectively suppress the vibration of the axial flow fan cover 3 and the ventilation axial flow fan 10, reducing the noise caused by vibration.
[0040] The axial flow fan cover 3 and the ventilation axial flow fan 10 are assembled on the ventilation and air exchange device. The ventilation and air exchange device drives the ventilation axial flow fan 10 and the axial flow fan cover 3. By using the axial thrust generated when the impeller rotates, the air is pushed to flow along the axial direction to achieve large-area ventilation and air exchange. The user can then fold the foldable wing-type ventilation cover 7 onto the flange 1, so that the ventilation axial flow fan 10 is exposed in the dehydration workshop. This not only expands the ventilation space of the ventilation and air exchange device, but the ventilation cover 11 and the built-in hole 9 can also expand the ventilation and air exchange vents.
