Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning units, and in particular to a filter-type aviation ground air conditioning unit. Background Technology

[0002] As an indispensable piece of equipment in aviation facilities such as airports and aprons, aviation ground air conditioning units mainly function to provide a suitable temperature and humidity environment for aircraft and ground staff, ensuring the normal operation of aircraft and the comfort of personnel during parking and maintenance. However, in the long-term operation, aviation ground air conditioning units face many challenges, the most prominent of which is the problem of dust and pollutant treatment.

[0003] In existing aviation ground air conditioning units, although most equipment is equipped with dust filters to prevent dust from entering the air conditioning system, cleaning the dust on the surface of the dust filters often relies on regular manual cleaning. This not only increases maintenance costs but also has relatively low cleaning efficiency. In addition, even if cleaning is carried out, because dust particles are small and easily affected by airflow, some dust often drifts into the air during the cleaning process, causing secondary pollution and affecting the cleanliness of the surrounding environment.

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a filter-type aviation ground air conditioning unit, which aims to clean the dust screen at the air inlet of the air conditioning unit to avoid affecting the air intake speed and to collect the generated dust.

[0028] Example

[0029] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a filter-type aviation ground air conditioning unit, including a casing 1.

[0030] The filter mechanism 2 includes a slide 21 symmetrically fixedly connected to the bottom of the casing 1. The two slides 21 are slidably fitted with a filter plate 22 for filtering air. A dustproof net 24 is fixedly connected to the air inlet on the outer wall of the casing 1 to prevent dust from entering.

[0031] The interior of the chassis 1 is equipped with a cleaning mechanism 3 for cleaning dust on both sides of the dust filter 24, and the outer wall of the chassis 1 is equipped with an adsorption mechanism 4 for adsorbing dust. A maintenance plate 23 is fixedly connected to the outer wall of the chassis 1 at the position corresponding to the filter plate 22.

[0032] Using the above technical solution, the filter mechanism 2 is the core part of the air conditioning unit. It achieves flexible installation and removal of the filter plate 22 through a pair of symmetrically fixed slides 21 at the bottom of the casing 1. The two slides 21 are designed with a precise sliding sleeve structure, which allows the filter plate 22 to slide in or out easily, making it convenient for users to replace or clean it as needed, thereby maintaining efficient air filtration capacity. In addition, a dustproof net 24 is specially added to the air inlet on the outer wall of the casing 1. This barrier effectively blocks the intrusion of large particles of dust from the outside, extending the service life of the filter plate 22. The cleaning mechanism 3 can be started automatically or manually at regular intervals. Through physical brushing, the dust accumulated on the dustproof net is quickly removed, ensuring that the air inlet is unobstructed and avoiding affecting the overall performance of the air conditioning unit. The adsorption mechanism 4 can efficiently collect and fix the dust cleaned by the cleaning mechanism 3, avoiding secondary pollution, and also facilitating subsequent centralized processing and recycling.

[0033] The cleaning mechanism 3 includes a drive motor 31 fixedly connected to the outer wall of the housing 1. A reciprocating lead screw 32 is fixedly connected to the output end of the drive motor 31, and extends to the inner wall of the housing 1, rotating and sleeved with the inner wall. A reciprocating collar 321 is threaded onto the outer wall of the reciprocating lead screw 32. Fixed brackets 33 are symmetrically fixedly connected to the outer wall of the housing 1. Guide rods 34 are fixedly sleeved inside the two fixed brackets 33. Guide collars 341 are slidably sleeved on the outer wall of the guide rods 34. The reciprocating collar 32... A connecting plate 35 is fixedly connected to the outer wall of the chassis 1 and is connected to the guide collar 341. A connecting frame 37 is fixedly connected to the bottom end of both the reciprocating collar 321 and the guide collar 341. A cleaning cotton 38 for cleaning the outer wall of the dustproof net 24 is fixedly connected to the opposite side of the two connecting frames 37. A guide frame 39 is fixedly connected to both the inner and outer walls of the chassis 1, and the connecting frame 37 and the guide frame 39 are slidably sleeved. A corrugated strip 36 is fixedly connected to the outer wall of the connecting plate 35, and the other end of the corrugated strip 36 is fixedly connected to the inner wall of the chassis 1.

[0034] Using the above technical solution, the reciprocating collar 321 can move precisely back and forth along the trajectory of the reciprocating screw. In order to enhance the stability and guidance of the structure, two fixed brackets 33 are symmetrically fixedly connected to the outer wall of the housing 1. Guide rods 34 are fixedly sleeved inside these two brackets. Guide collars 341 are slidably sleeved on the outer wall of the guide rods 34 and are tightly connected to the reciprocating collar 321 through the connecting plate 35 to form a stable motion frame. The other end of the corrugated strip 36 is fixedly connected to the inner wall of the housing 1. This design not only ensures the stability of the connecting plate 35 during movement, but also allows it to undergo elastic deformation to a certain extent to adapt to small displacements under different working conditions. With the start of the drive motor 31, the cleaning cotton 38 is driven by the reciprocating screw 32 to precisely reciprocate along the outer wall of the dustproof net 24, effectively removing the dust and impurities accumulated on the dustproof net.

[0035] The adsorption mechanism 4 includes an air pump 41 fixedly connected to the outer wall of the housing 1. The air pump 41 is fixedly connected to a first air pipe 44. The inner and outer walls of the housing 1 are fixedly connected to a first air hood 46 and a second air hood 47, respectively. The outer walls of the first air hood 46 and the second air hood 47 are fixedly connected to a second air pipe 45 that communicates with the inside of the first air pipe 44. The exhaust end of the air pump 41 is fixedly connected to a third air pipe 48. A pad 42 is fixedly connected to the outer wall of the housing 1 below the air pump 41. A filter box 43 is fixedly connected to the top of the pad 42. The air inlet end of the filter box 43 and the end of the third air pipe 48 are connected by a threaded sleeve 49 through a threaded limit connection.

[0036] Using the above technical solution, the first suction hood 46 is located on the inner wall of the casing 1 and is mainly used to adsorb dust and impurities generated by the cleaning mechanism 3 when cleaning the dustproof net 24. The second suction hood 47 is located on the outer wall of the casing 1 and can further capture tiny particles that may escape into the external environment, ensuring the cleanliness and hygiene of the entire air conditioning unit's operating environment. The outer walls of both suction hoods are fixedly connected to a second air pipe 45 that communicates with the inside of the first air pipe 44, ensuring that dust can smoothly enter the suction pump 41. The filter box 43, as a key component of the adsorption mechanism, is equipped with high-efficiency filter material, which can finely filter and separate the inhaled dust, ensuring that the emitted gas meets environmental protection standards. In order to enhance the structural stability and connection reliability, the air inlet end of the filter box 43 and the end of the third air pipe 48 are tightly connected by a threaded sleeve 49 with a threaded limit connection, avoiding air leakage caused by loose connection.

[0037] Working Principle: Due to prolonged use, a large amount of dust accumulates at the air intake of chassis 1. Therefore, the dust filter 24 at the air intake needs to be cleaned. The user can start the drive motor 31 to rotate the reciprocating screw 32. The reciprocating screw 32 and the reciprocating collar 321 cooperate to realize the reciprocating motion of the reciprocating collar 321, and simultaneously drive the connecting plate 35 and the guide collar 341 to slide on the outer wall of the guide rod 34. During this process, the connecting plate 35 will squeeze the corrugated strip 36, causing it to contract. The movement of the reciprocating collar 321 and the guide collar 341 will drive the connecting frame 37 and the cleaning cotton 38 to move. Because the cleaning cotton 38 and the dust filter 24... The dust filter 24 is in contact with the outer wall, thus cleaning both sides of the dust filter 24 and avoiding excessive dust that could reduce ventilation efficiency. During this process, the dust will rise due to air fluctuations, so the adsorption mechanism 4 will start working. Since the first suction hood 46 and the second suction hood 47 are located on the inner and outer walls of the housing 1 respectively, when the dust rises, the suction pump 41 starts working, moving the surrounding air through the first suction hood 46 and the second suction hood 47, and sending the gas into the interior of the filter box 43 through the first air pipe 44 and the third air pipe 48. The dust will also enter the interior of the filter box 43 with the gas, completing the dust treatment.
