Description

Technical Field

[0001] The utility model relates to air compressor equipment, and more specifically, to an air compressor. Background Art

[0002] As Figure 1 shown, the intake filter element 2 in the existing air compressor 1 is arranged in a single layer, and a total of 3 intake filter elements 2 are placed. The whole of the intake filter element 2 is circular. Therefore, the maximum filtration area of a single intake filter element 2 can only reach 19 m 2 , and the total filtration area of the 3 intake filter elements 2 is 19 * 3 = 57 m 2 .

[0003] As Figure 2 shown, the intake filter element 2 is installed in the air compressor 1 through a filter element mounting bracket 3, and the filter element mounting bracket 3 is installed on the ceiling plate 4 in the air compressor 1 by fasteners. The fasteners include 2 nuts 5 and 1 gasket 6. One of the nuts 5 is first sleeved on the bottom feet of the filter element mounting bracket 3. The bottom feet pass through the ceiling plate 4, then the gasket 6 and the other nut 5 are sleeved on, and finally the 2 nuts 5 are tightened.

[0004] In summary, using the existing circular intake filter element will result in limited filtration area, and the intake filter element is prone to damage and has a short service life, making the cleanliness of the inlet air of the air compressor unable to be effectively guaranteed. To achieve better use effects, only by increasing the filtration chamber space of the air compressor can this be achieved. In addition, the filter element mounting bracket is installed by fasteners. Due to the vibration generated during the operation of the air compressor, the fasteners may become loose, and a certain component of the fasteners may fall into the air compressor, causing damage to the air compressor.

[0038] In order to better understand the above technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0039] Combined with Figure 3 and Figure 4 as shown, an air compressor 100 provided by the present utility model:

[0040] A plurality of rectangular filter elements 7 are arranged in the filter chamber 101 of the air compressor 100.

[0041] A plurality of rectangular filter elements 7 are arranged in 2 layers × 2 in the filter chamber 10, for a total of 4 rectangular filter elements 7.

[0042] Each rectangular filter element 7 is fixedly connected to the ceiling 102 of the filtration chamber 101 through a filter element mounting bracket 8.

[0043] The rectangular filter elements 7 are arranged in a 2×2 pattern, and the filtration area of a single rectangular filter element 7 can be 26 m 2 , and the total filtration area of the 4 rectangular filter elements 7 can reach 26×4 = 104 m 2 .

[0044] Combined with Figure 5 as shown, each rectangular filter element 7 includes an inner skeleton 71, an outer skeleton 72, filter paper 73, an upper end cap 74, and a lower end cap 75.

[0045] The outer skeleton 72 is arranged in a V shape, and an opening structure is formed at the upper end position of the outer skeleton 72.

[0046] The inner skeleton 71 is also arranged in a V shape and is installed inside the outer skeleton 72, and an opening structure is also formed at the upper end position of the inner skeleton 71.

[0047] The large-mouth end and small-mouth end of the inner skeleton 71 and the outer skeleton 72 are arranged on the same side.

[0048] The lower end positions of the outer skeleton 72 and the inner skeleton 71 are both connected to the lower end cap 75, and a closed structure is formed through the lower end cap 75.

[0049] The upper end cap 74 is installed at the position between the upper end positions of the outer skeleton 72 and the inner skeleton 71, and a closed structure is formed through the upper end cap 74.

[0050] A rectangular through-hole is opened at the central position of the upper end cap 74, and the through-hole is connected to the opening structure at the upper end position of the inner skeleton 71 and penetrates through the inside of the inner skeleton 71.

[0051] The filter paper 73 is laid between the inner skeleton 71 and the outer skeleton 72 to form a filtration surface.

[0052] The long side and short side of the through-hole are adapted to the long side and short side of the opening structure at the upper end position of the inner skeleton 71.

[0053] A sealing strip 76 is provided on the edge of the through-hole, and the sealing strip 76 is located on the outer surface of the upper end cap 74.

[0054] A guard plate 77 is further provided between the side positions of the outer skeleton 72 and the side positions of the inner skeleton 71.

[0055] The overall rectangular filter element 7 adopts a rectangular structure. Through the V-shaped design of the inner skeleton 5 and the outer skeleton 3, it is divided into two layers of filter paper up and down, and the opening degree at the upper end is greater than that at the lower end, forming a conical structure.

[0056] The cross-section of the rectangular filter element 7 is set to be rectangular, with more folding distances and folding numbers compared to the circular filter cartridge, and the filtration area is increased by 36.8% compared to that of the circular filter cartridge.

[0057] The longitudinal section of the rectangular filter element 7 is set to be conical, which can optimize the air flow path. Compared with other shapes, the conical design enables the air to flow more smoothly when entering the air filter element, reducing the flow resistance and eddy current phenomenon, and is more helpful to ensure that the air can pass through the filter element more efficiently, thereby improving the intake efficiency.

[0058] The conical cross-section of the rectangular filter element 7 can also improve the filtration efficiency of the air filter element. Due to the optimization of the air flow path, the particulate matter in the air is more easily trapped when passing through the air filter element. The conical cross-section design can ensure the uniform distribution of the particulate matter inside the air filter element and improve the utilization efficiency of the filtration area.

[0059] In addition, the conical cross-section of the rectangular filter element 7 also has a certain self-cleaning function. During the use of the air filter element, some particulate matter may adhere to the surface of the air filter element. Due to the conical design, when the air flow passes through the air filter element, it can generate a certain scouring effect, which helps to wash away the particulate matter adhering to the surface of the air filter element, thereby extending the service life of the air filter element.

[0060] Combined Figure 7 and Figure 8 As shown, the filter element mounting bracket 8 includes square tubes 81, cover plates 82, and reinforcing ribs 83.

[0061] There are 4 square tubes 81, and the rear ends are all welded to the flower plate 102.

[0062] There are 4 reinforcing ribs 83, which are respectively connected between adjacent 2 square tubes 81, so that a rectangular bracket for placing the rectangular filter element 7 is integrally formed between the 4 square tubes 81 and the 4 reinforcing ribs 83.

[0063] Screws 84 are connected to the front ends of the square tubes 81, and locking nuts 85 are arranged on the screws 84.

[0064] The cover plate 82 is set to be rectangular, and through holes adapted to the positions of the screws 84 are opened at the four corner positions thereof.

[0065] When installing the rectangular filter element 7, it only needs to be inserted into the filter element mounting bracket 8, the cover plate 82 is covered, and then it is fastened with the locking nut 83, and the installation and maintenance are very convenient.

[0066] The reinforcing ribs 83 can be made of round steel into an N shape.

[0067] The utility model maximizes the utilization of the space in the filter chamber 101 of the air compressor 100 by using a rectangular filter element 7, and installs a filter element with a larger filtration area in a limited space. The filter element mounting bracket 8 and the ceiling 102 are fixedly connected by welding to prevent foreign objects from falling into the air compressor 100, and fundamentally solve the problem that the air compressor 100 is damaged due to foreign objects falling into the air compressor 100.
