Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention for air compressors, in particular to a variable frequency screw air compressor with good dust prevention performance. Background Art

[0002] An air compressor includes a motor, oil and gas barrel, cooler, filter, etc. It is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. The operating environment of an air compressor generally requires clean air. If the environment is poor, the inhaled air will be very dirty, which will cause the inside of the air compressor to be very dirty and affect its service life. Therefore, the operating environment of the air compressor must meet the requirements of clean air.

[0003] However, in reality, air compressors are mostly used in industrial plants, where the operating environment is relatively poor. Generally, air compressors need to be placed in the corners of the factory, where there is a lot of dust. For air compressors with heat dissipation holes, a single-layer dustproof net is generally provided. However, the dustproof effect of the single-layer dustproof net is poor, resulting in dust accumulation and entry into the air compressor chassis after long-term use of the air compressor. Eventually, the dust enters various line connectors and circuit boards, resulting in poor line contact, thereby affecting the use of the air compressor. Therefore, stronger dustproof measures need to be taken in actual use. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0030] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the specific details or the specific manner described herein.

[0031] See also Figure 1-6The utility model provides a variable frequency screw air compressor with good dustproof performance, comprising: a box body 1, a heat dissipation net 2, a variable frequency screw air compressor assembly 3, and an air inlet dustproof device 4, wherein the heat dissipation net 2 is arranged on one side of the box body 1; the variable frequency screw air compressor assembly 3 is installed in the box body 1 and is located on one side of the heat dissipation net 2; the air inlet dustproof device 4 is equipped in the box body 1 and is installed on one side of the heat dissipation net 2; wherein the air inlet dustproof device 4 comprises a frame 41 and a dustproof fan blade plate 42, a plurality of obliquely installed dustproof fan blade plates 42 are arranged on the frame 41, the frame 41 is installed on one side of the heat dissipation net 2, and the dustproof fan blade plates 42 are located between the heat dissipation net 2 and the variable frequency screw air compressor assembly 3.

[0032] When in use, the air inlet dust prevention device 4 is installed between the heat dissipation net 2 and the variable frequency screw air compressor assembly 3. When the air compressor is working, the dust in the factory is initially blocked by the heat dissipation net 2, and part of it enters the box body 1. The dust is blocked by the oblique dust-proof fan blade plate 42 and will adhere to the dust-proof fan blade plate 42, blocking the dust and preventing it from continuing to float in. It has the effect of both air intake and dust prevention for the air compressor.

[0033] According to some embodiments of the present application, the dustproof blade plate 42 may optionally adopt a carbon crystal plate structure, which is a composite material composed of carbon fiber and resin, and a large amount of static electricity may accumulate on its surface, thus absorbing dust.

[0034] According to some embodiments of the present application, optionally, notches 43 for inserting the dustproof blade plate 42 are provided on both sides of the frame 41. Through the insertion of the notches 43, the dustproof blade plate 42 can be loaded and unloaded on the frame 41.

[0035] According to some embodiments of the present application, optionally, the dustproof fan blade plate 42 includes a main board 421, a sub-board 422, a baffle 423, a socket 424, and a piston plate 425. A socket 424 is provided on one side of the main board 421, and the piston plate 425 is inserted into the main board 421. A baffle 423 for blocking the piston plate 425 is installed at the socket 424 of the main board 421. One side of the sub-board 422 is inserted into the socket 424 and connected to the piston plate 425. The main board 421 and the sub-board 422 are respectively plugged into the frame 41 through the slot 43. The common dust-proof blade plate 42 is fixedly connected to the frame 41 by welding. When the dust-proof blade plate 42 needs to be cleaned of the adsorbed dust, it needs to be removed as a whole. The dust-proof blade plate 42 cannot be removed from the frame 41 one by one. The dust-proof blade plate 42 is installed obliquely, which will cause greater obstacles during cleaning and increase the difficulty of cleaning. Therefore, the present application uses the auxiliary plate 422 to be retractable on the main board 421. The retractable method is to allow the auxiliary plate 422 to penetrate into the main board 421 through the socket 424 and be connected to the piston plate 425. The plug The opening 424 has a baffle 423 to limit the piston plate 425 from moving out of the main board 421, so that the sub-plate 422 can be pulled to extend or retract on the main board 421. During installation, it only needs to be adjusted to the corresponding length and inserted into the frame 41 through the slot 43. After insertion, the sub-plate 422 or the main board 421 is stretched to make it stuck on the frame 41. On the contrary, during removal, it is only necessary to shorten the length of the sub-plate 422 on the main board 421 and remove it from the slot 43, so that the dustproof fan blade plates 42 can be removed one by one on the frame 41, making it easier to clean the adhering dust.

[0036] According to some embodiments of the present application, optionally, a rubber ring 426 is sleeved on the piston plate 425, and the rubber ring 426 fits against the inner wall of the main board 421. This has the effect of increasing the friction between the piston plate 425 and the main board 421, so that the piston plate 425 will move in the main board 421 only when the auxiliary plate 422 is pulled by an external force, effectively preventing the auxiliary plate 422 from automatically shortening and moving due to equipment vibration after installation.

[0037] According to some embodiments of the present application, optionally, a bolt 427 is threadedly connected to the main board 421, and the bolt 427 is screwed into the main board 421 and threadedly connected to the screw hole 428 on the piston plate 425. After the length of the main board 421 and the sub-board 422 are adjusted and installed on the frame 41, in order to increase the stability between the main board 421 and the sub-board 422, the bolt 427 is screwed into the main board 421 and connected to the piston plate 425, and the piston plate 425 is fixed in the main board 421, so that the sub-board 422 is fixed in the main board 421.
