Description

Technical Field

[0001] The utility model relates to the technical field of air supply mechanisms, in particular to an air supply and heat dissipation mechanism with a dust filtering function. Background Art

[0002] A prefabricated substation utilizes a prefabricated cabin structure, integrating key substation equipment. This system integrates transformers, high-voltage switchgear, secondary protection equipment, and other key components within the prefabricated cabin, achieving a high degree of integration and a compact overall structure. Therefore, specialized ventilation and cooling measures are typically required to prevent heat buildup within the cabin, which could affect the proper operation of electronic equipment.

[0003] The utility model with announcement number CN217057899U discloses a dust-filtering high-efficiency air outlet in the field of air outlet technology. After the power is turned on, the internal fan drives the gas from the air duct into the connecting air duct, and then passes through the double-layer filtration of the primary filter and the high-efficiency filter, which can filter out the floating dust particles in the gas and prevent dust from entering the inner cavity of the air supply box. During this period, the gas also passes through the activated carbon filling layer, which can adsorb organic pollutants and certain inorganic substances in the gas, and then remove the odor in the gas. At the same time, the activated carbon can adsorb and remove water vapor in the gas and reduce the humidity of the air.

[0004] The above structure plays a role in filtering and intercepting floating dust in the air through the filter structure provided. However, after long-term use, a certain amount of floating dust will adhere to the surface of the filter and affect the filtering effect of the filter. In addition, due to the lack of automatic cleaning measures, the air outlet needs to be stopped and then manually cleaned, which is inconvenient to use. Therefore, in order to solve the above problems, an air supply and heat dissipation mechanism with dust filtering function is proposed. Utility Model Content

During the air supply and filtering process, the driving mechanism works regularly to drive the rotating dust removal mechanism to rotate, thereby cleaning the dust attached to the surface of the filter cartridge. In addition, when deep cleaning is required, the blower stops working. At this time, the dust blowing mechanism sends in a reverse high-pressure airflow, which diffuses from the inside of the filter cartridge to the outside, blowing off the dust on the filter cartridge, and working in conjunction with the rotating dust removal mechanism, can further improve the effect of automatic cleaning, and solves the technical problem in the prior art that floating dust will adhere to the surface of the filter screen after long-term use, affecting the filtering effect, and that manual cleaning is required, making it inconvenient to use.

During the air supply and filtering process, the driving mechanism 5 works regularly to drive the rotating dust removal mechanism 4 to rotate, thereby cleaning the dust attached to the surface of the filter cartridge 3. In addition, when deep cleaning is required, the air blower 8 stops working. At this time, the dust blowing mechanism 6 sends in a reverse high-pressure airflow, which diffuses from the inside of the filter cartridge 3 to the outside, blowing off the dust on the filter cartridge 3, and working in conjunction with the rotating dust removal mechanism 4, can further improve the effect of automatic cleaning.

[0035] like Figure 3 As shown, the filter cartridge 3 includes a cartridge rack 31, on which a number of air outlets 32 are opened, and the cartridge rack 31 is covered with a mesh cover 33, and a connecting plate 34 is fixedly provided at the upper end of the cartridge rack 31.

The end of the elastic connecting arm 43 is fixedly connected to a brush plate 44 that fits the mesh sleeve layer 33. Through the above-mentioned structural form, when the outer ring of the mounting bearing 41 rotates, the connecting part 42 will drive the brush plate 44 to rotate synchronously, thereby cleaning the surface of the mesh sleeve layer 33, and the elastic connecting arm 43 can apply thrust to make the mesh sleeve layer 33 always fit the surface of the mesh sleeve layer 33, thereby ensuring the cleaning effect.

[0037] In addition, the driving mechanism 5 includes a driving motor 51, a driving gear 52 and a driven gear 53, wherein the driving motor 51 is installed on the partition 2, and its output shaft is fixedly connected to the driving gear 52, and the driven gear 53 is sleeved on the outer ring of the mounting bearing 41, and the driving gear 52 and the driven gear 53 are engaged with each other. Through the above-mentioned structural form, when the driving motor 51 is working, it will drive the driving gear 52 to rotate, and then drive the driven gear 53 engaged with the driving gear 52 to rotate, and the rotation of the driven gear 53 will drive the outer ring of the mounting bearing 41 to rotate, providing the necessary structural basis for the rotation of the brush plate 44.

[0038] like Figure 2 、 Figure 4 As shown, the dust blowing mechanism 6 includes a main high-pressure air pipe 61, which is sealed with a high-pressure branch pipe 62 extending into the filter cartridge 3, and the end of the high-pressure branch pipe 62 is connected to an air outlet head 63. Through the above-mentioned structural form, the high-pressure airflow extending from the outside can be transmitted to the high-pressure branch pipe 62 through the main high-pressure air pipe 61, and finally blown out through the air outlet head 63, thereby blowing off the dust on the surface of the mesh sleeve layer 33.

[0039] Among them, the dust filter box 1 is provided with an air inlet 13 connected to the clean area. One end of the air inlet 13 is tightly connected to the main high-pressure air pipe 61, and the other end is tightly connected to the external high-pressure air pump. Through the above structure, when deep cleaning is required, the external high-pressure air pump works and blows high-pressure air into the main high-pressure air pipe 61 to blow off the dust.

[0040] like Figure 2 As shown, the dust filter box 1 is provided with an air inlet 11 and an air outlet 12, wherein the air inlet 11 is connected to the dust removal area, and the air outlet 12 is connected to the clean area. Through the above-mentioned structural form, a complete air duct is formed, that is, under the action of the blower 8, air enters from the air inlet 11 and is discharged from the air outlet 12 after being filtered.

[0042] The use principle and use process of this utility model:

[0043] The blower 8 works to supply air and dissipate heat, and the filter cartridge 3 will filter the air before it is sent in to prevent dust from entering the cabin. Specifically, when the air is drawn in, it will pass through the mesh cover 33, and then flow from the air outlet 32 ​​to the top of the cartridge rack 31, and finally enter the clean area. When the air passes through the mesh cover 33, it will filter and block the dust in the air.

[0044] In addition, during the air supply and filtering process, the driving mechanism 5 works regularly to drive the rotating dust removal mechanism 4 to rotate, so as to clean the dust attached to the surface of the filter tube 3 without manual operation. This is manifested as follows: when the driving motor 51 works, it drives the driving gear 52 to rotate, and then drives the driven gear 53 engaged with the driving gear 52 to rotate, and the rotation of the driven gear 53 drives the outer ring of the mounting bearing 41 to rotate. When the outer ring of the mounting bearing 41 rotates, the connecting member 42 drives the brush plate 44 to rotate synchronously, so as to clean the surface of the mesh sleeve 33, and the elastic connecting arm 43 can apply thrust so that the mesh sleeve 33 always fits the surface of the mesh sleeve 33, thereby ensuring the cleaning effect.

[0045] In addition, when deep cleaning is required, the blower 8 stops working. At this time, the dust blowing mechanism 6 sends in a reverse high-pressure airflow, which diffuses from the inside of the filter cartridge 3 to the outside, blowing off the dust on the filter cartridge 3, and working in conjunction with the rotating dust removal mechanism 4, can further improve the effect of automatic cleaning.

[0046] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments.
