Description

Technical Field

[0001] The utility model relates to an air compressor intake mechanism, specifically to a uniform air intake structure for an air compressor, belonging to the technical field of air compressors. Background Art

[0002] An air compressor, also known as an air compressor, is the main body in an air source device. It is a device that converts the mechanical energy of a prime mover into gas pressure energy and is a pneumatic pressure generating device for compressed air. When the air compressor works, a connecting rod is driven by a power device to perform reciprocating motion in a cylinder, thereby completing the cycle of air intake and air outlet.

[0003] However, the gas of a conventional air compressor directly enters the air compressor from an intake pipeline. The flow velocities of the gas in each part of the intake pipeline are inconsistent, which affects the intake efficiency of the total air flow and also affects the subsequent operation of the air compressor. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an air intake structure for an air compressor.

[0005] To solve the above technical problem, the air intake structure for an air compressor provided by the utility model includes an intake assembly and a flow equalizing assembly. The intake assembly is connected to the flow equalizing assembly in a through manner. The intake assembly is used for allowing air flow to enter the air compressor. The flow equalizing assembly is connected to the inner cavity of the air compressor in a through manner. The flow equalizing assembly includes several flow equalizing plates. A plurality of flow equalizing holes are evenly arranged on the flow equalizing plates. The aperture sizes at both ends of the flow equalizing holes are inconsistent. The end with a smaller aperture of the flow equalizing hole faces the intake assembly. The orientation of the flow equalizing hole is consistent with the air flow movement direction.

[0006] In the utility model, several of the flow equalizing plates are detachably arranged in the flow equalizing assembly. All the flow equalizing holes on two adjacent flow equalizing plates are at different horizontal heights.

[0007] In the utility model, the flow equalizing holes on the flow equalizing plate closest to the air compressor cover the entire flow equalizing plate.

[0008] In the utility model, a filter assembly is hermetically arranged between the flow equalizing assembly and the intake assembly. A filter screen is inclined in the filter assembly. The filter screen is used for filtering impurities in the air flow.

[0009] In the utility model, a storage bin is arranged below the filter screen. The length of the storage bin is the same as the length of the filter assembly. The lowest end of the inclined filter screen is located above the storage bin.

[0010] In the present utility model, the storage bin and the filter assembly are detachably connected through a disassembly assembly, and the disassembly assembly is hermetically connected to the storage bin and the filter assembly by means of a sealing ring.

[0011] Advantages of the present utility model:

[0012] The present utility model uses a plurality of flow equalizing plates to equalize the airflow entering the air compressor, ensuring that the flow velocities of all parts of the airflow entering the air compressor are consistent, and improving the air intake efficiency of the air compressor.

[0013] In the present utility model, a plurality of flow equalizing plates are detachably installed in the flow equalizing assembly, facilitating subsequent maintenance and replacement. Moreover, the flow equalizing holes on each flow equalizing plate are staggered, ensuring that the airflow can occupy the entire flow equalizing assembly as much as possible and improving the air intake efficiency.

[0014] In the present utility model, the filter assembly can effectively filter out the hard impurities existing in the airflow, avoiding the situation that the subsequent flow equalizing assembly and the interior of the air compressor are damaged by hard impurities, and improving the service life of the air compressor.

[0015] The detachable storage bin can effectively store the impurities filtered by the filter net, preventing the accumulation of impurities and affecting the filtering effect. Description of the drawings

[0027] The following will describe in detail some embodiments of the present utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] As Figure 1 and Figure 2 shown, the air intake structure of the air compressor 3 in this embodiment includes an air intake component 1 and a flow equalizing component 2. The air flow entering the air compressor 3 enters the flow equalizing component 2 from the air intake component 1 for flow equalization. The flow equalizing component 2 is connected to the inner cavity of the air compressor 3 in a through manner. The flow equalizing component 2 contains multiple flow equalizing plates 4. The number of flow equalizing plates 4 can be adjusted according to the actual situation. A plurality of flow equalizing holes 5 are evenly arranged on the flow equalizing plates 4. The flow equalizing holes 5 are not only used for flow splitting, but also evenly split the flow velocity of the air flow. The aperture sizes at both ends of the flow equalizing holes 5 are inconsistent. The end with a smaller aperture of the flow equalizing holes 5 faces the air intake component 1, and the orientation of the flow equalizing holes 5 is consistent with the air flow movement direction.

[0029] The air flow entering the air compressor 3 is equalized by several flow equalizing plates 4, ensuring that the flow velocity of the intake air flow is uniform and avoiding the situation of backflow impacting the air flow, which affects the intake efficiency.

[0030] In this embodiment, several flow equalizing plates 4 are all detachably arranged in the flow equalizing component 2. When maintenance is required, it is convenient for workers to detach the flow equalizing plates 4 for replacement and maintenance. All the flow equalizing holes 5 on two adjacent flow equalizing plates 4 are at different horizontal heights.

[0031] In this embodiment, the flow equalizing holes 5 on the flow equalizing plate 4 closest to the air compressor 3 cover the entire flow equalizing plate 4, and the flow equalizing holes 5 on the last flow equalizing plate 4 through which the air flow passes cover the entire flow equalizing plate 4, ensuring the intake area as much as possible and improving the intake efficiency.

[0032] In this embodiment, the flow equalizing component 2 and the air intake component 1 are hermetically connected through a filtering component 6. A filter screen is inclinedly arranged in the filtering component 6. The filter screen is used to filter impurities in the air flow. Through the filtering of the filter screen, hard impurities in the air flow can be effectively filtered, avoiding hard impurities entering the inner cavity of the air compressor and causing impacts, and ensuring the safety of the inner cavity of the air compressor.

[0033] In this embodiment, a storage bin 7 is arranged below the filter screen. The length of the storage bin 7 is the same as the length of the filtering component 6. The lowest end of the inclined filter screen is located above the storage bin 7. The storage bin 7 is used to store the filtered impurities, avoiding the accumulation of impurities affecting the use of the filter screen and ensuring the service life of the filter screen.

[0034] In this embodiment, the storage bin 7 and the filtering component 6 are detachably connected through a disassembly component. The disassembly component is hermetically connected to the storage bin 7 and the filtering component 6 by means of a sealing ring. The detachable storage bin 7 facilitates the user to disassemble it and timely clean the impurities accumulated in the storage bin 7.

[0035] When the present utility model is in use, air flow enters from the air inlet component 1, passes through the filtering component 6, and the impurities are filtered out by the filter screen 7 in the filtering component 6 and fall into the storage bin 7 below, and then enter the flow equalizing component 2 for flow equalization. After flow equalization, it enters the inner cavity of the air compressor 3. The whole utility model not only ensures the air intake efficiency but also improves the service life of the air compressor.

[0036] In the above description, many specific details are elaborated to fully understand the present utility model. However, the above examples are only the preferred implementation modes of the present utility model and cannot be used to limit the scope of the rights of the present utility model. Simple modifications and equivalent changes made to the above examples based on the essence of the present utility model still fall within the scope of the present utility model.
