DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0020] like Figures 1 to 4 In one embodiment of the replacement-type pulse dust removal station air supply device of the present invention, a housing 1 is provided with a fresh air inlet duct 11 for communication with the outside world, a return air outlet 12 for communication with the indoor environment, and an outlet 13 for exhausting the air flow. A centrifugal fan 3 is provided within the housing 1 to drive the air flow, and an air mixing chamber 2 is provided within the housing 1, connecting the fresh air inlet duct 11 and the return air outlet 12. The air mixing chamber 2 is formed by a partition 21 and a transverse plate 22 intersecting the top wall of the housing 1 and enclosing the side walls of the housing 1. The partition 21 is provided with a flow port 23 connecting the supply air flow with the outlet 13. The outlet 13 is provided with a downwardly extending outlet duct 14. This design mixes the fresh air flow with the indoor air flow, reducing the temperature and humidity differences between the two air flows. The fresh air flow is then directly delivered to the work area through an outlet duct extending directly into the work area, where it contacts the workers. This ensures timely airflow renewal in the work area and reduces direct stimulation from the outside air to the workers, thus ensuring a comfortable working environment.

[0021] Specifically, an exhaust hood 15 is provided at the end of the air outlet duct 14 away from the machine body 1. A plurality of exhaust holes 151 are provided on the sidewall of the exhaust hood 15. A bottom plate 152 is provided on the exhaust hood 15 to guide the airflow out of the exhaust holes. The exhaust hood adjusts the airflow to diffuse horizontally in all directions, ensuring the airflow diffusion area and promoting the rapid spread of fresh air throughout the work area.

[0022] Specifically, a cylindrical filter 24 whose inner cylinder is connected to the flow port 23 is mounted on the partition plate 21 .

[0023] Specifically, a pulse nozzle 4 is provided in the body 1 and faces the inner tube of the cylindrical filter 24; the pulse nozzle 4 is connected to the air storage tank 6 through a pulse valve. The pulse device cooperates with the filter to clean the dust accumulated in the filter in time to ensure the smooth flow of air in the equipment.

[0024] Specifically, the partition 21 is tilted downward away from the return air outlet 12, and the angle between the partition 21 and the horizontal direction is 70° to 80°. The filter installed on the tilted partition ensures that the airflow has sufficient contact with the filter and is fully filtered.

[0025] Specifically, a heat exchanger 5 is provided in the machine body 1 and is arranged between the air outlet 13 and the flow port 23 to communicate with the external heat source.

[0026] Specifically, the horizontal plate 22 is arranged to be tilted downward in the direction close to the return air port 12; a dust collecting sealing plate 17 capable of opening and closing the dust collecting port 16 is provided on the side wall of the machine body 1.

[0027] Specifically, the outer shell of the machine body 1 is a three-layer composite plate; the three-layer composite plate comprises a composite color steel plate layer, a polyurethane foam layer, and a composite color steel plate layer from the inside to the outside.

[0028] Working principle: After the staff starts the equipment, the centrifugal fan 3 starts to drive the air flow. The fresh air from the outside enters the mixed air bin 2 from the fresh air inlet pipe 11, and the indoor air enters the mixed air bin 2 from the return air port 12. After the fresh air is mixed with the indoor air flow, the temperature is neutralized. After being filtered by the cylindrical filter 24, it is discharged from the flow port 23 connected to the inner cylinder of the cylindrical filter 24 and then enters the outlet pipe 14 connected to the air outlet after passing through the heat exchanger 5. The heat exchanger 5 is provided with a fin-type heat exchanger for air circulation, and is discharged directly into the working area from the exhaust hood 15 at the lower end of the outlet pipe 14, effectively reducing the natural diffusion path of the fresh air flow, and directly delivering the fresh air to the working area, greatly improving the content of the fresh air flow in the working area, and improving the comfort of the staff in the working area for the ambient air flow, and cooperating with the filter with a pulse device to timely remove dust from the filter mesh, ensuring the filtering effect of the filter, ensuring the smooth circulation of the airflow in the equipment, ensuring gas cleanliness while reducing equipment maintenance costs.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
