Description

Technical Field

[0001] This utility model belongs to the field of air compression technology, and in particular relates to a device suitable for air intake filtration in air compressor systems. Background Technology

[0002] Outdoor air enters the air compressor's compression chamber and undergoes three-stage compression. The compressed gas passes through air coolers connected between each compression stage, and water vapor is removed by automatic drain valves, producing refined compressed gas supplied to users. During compressor operation, various lubrication parts generate a large amount of frictional heat, which is carried by the lubricating oil to the oil cooler. Heat exchange occurs between the circulating cooling water in the cooling tower and the air cooler and oil cooler, releasing the heat energy into the atmosphere. To improve heat recovery efficiency and reduce the cooling load on the circulating cooling water, waste heat is recovered and reused for the production of high-temperature hot water and for hot water-type non-electric air conditioning refrigeration, thereby reducing the company's operating costs and advancing the company's exploration in energy conservation and emission reduction. However, the air compressor system still has the following drawbacks during air intake:

[0003] Air compressor systems are typically equipped with inlet filters. Outdoor air passes through the inlet filter and then enters the air compressor's compression chamber for three-stage compression. However, after prolonged use, the inlet filter is prone to becoming clogged, resulting in poor air intake performance of the air compressor. This leads to a decrease in the gas-electric ratio of the compressed air produced and phenomena such as equipment surge. Utility Model Content

[0004] The purpose of this utility model is to provide a device suitable for air intake filtration in air compressor systems. By setting up a corrugated hose, a first ring frame, a second ring frame, a stainless steel wire mesh, and filter cotton, it solves the problems of easy clogging of the air intake filter, resulting in poor air intake effect of the air compressor, reduced compressed air-electric ratio, and equipment surge.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a device suitable for air intake filtration in an air compressor system, including a corrugated hose, a first ring frame, a second ring frame, filter cotton, and a stainless steel wire mesh. The two ends of the corrugated hose are respectively provided with a first port and a second port, and the first port is provided with a first ring frame and a second ring frame. Stainless steel wire mesh is fixed in the inner cavity of the first ring frame and the second ring frame, and filter cotton is provided between the two stainless steel wire meshes.

[0007] A series of insert rods arranged in a ring array are fixed on one end face of the first ring frame facing the second ring frame. A limit block is fixed in the middle of the insert rod, and a threaded section is provided on the end of the insert rod away from the first ring frame. A through hole arranged in a ring array is opened through the second ring frame. The threaded section of the insert rod extends out of the second ring frame through the through hole and is screwed with a wing nut.

[0008] Furthermore, a sealing gasket is fixed on the inner wall of port one at one end of the corrugated hose, and the inner wall of the sealing gasket contacts the outer walls of ring frame one and ring frame two.

[0009] Furthermore, the outer wall of the first ring frame is provided with screw holes arranged in a ring array, and the port is screwed with bolts arranged in a ring array through the outer wall, with the tail end of the bolts passing through the sealing gasket and screwed into the screw holes on the outer wall of the first ring frame.

[0010] Furthermore, a pad is also fitted around the outer periphery of the bolt. The pad is located outside the first port, and the inner arc surface of the pad contacts the outer wall of the first port and fits against it.

[0011] Furthermore, the stainless steel wire mesh is woven by interlacing and evenly distributing stainless steel warp and weft wires.

[0012] Furthermore, the thickness of the filter cotton is equal to the spacing between the two stainless steel wire meshes, and the outer walls of the two ends of the filter cotton are respectively attached to the inner walls of the first and second ring frames.

[0013] This utility model has the following beneficial effects:

[0014] This utility model, by setting up a corrugated hose, a first ring frame, a second ring frame, a stainless steel wire mesh, and filter cotton to form a primary filter structure, is installed before the air intake filter of the air compressor system. This solves the problem of the air intake filter being easily clogged, leading to poor air intake effect of the air compressor, reduced compressed air-to-electricity ratio, and equipment surge. The second port of the corrugated hose is connected to the air intake duct, and the air intake filter of the air compressor system is placed inside the air intake duct. After connecting the corrugated hose, a first ring frame and a second ring frame are set inside the first port of the corrugated hose, and a filter is placed between the stainless steel wire mesh inside the first and second ring frames. The filter cotton forms a primary filter, filtering dust and fluff from the outdoor fresh air. The primary filter is easy to clean regularly, reducing the burden and pressure on the post-filter and extending its service life. It allows outdoor fresh air to flow smoothly into the air compressor, avoiding equipment surge caused by dirt and blockage, and significantly improving the air-to-electricity ratio of the compressed air system. The air-to-electricity ratio of the modified air compressor is 9.0. The primary filter is replaced regularly, and the air compressor surge caused by filter blockage is greatly reduced. Before the modification, the air compressor had an air-to-electricity ratio of 8.8, and air compressor surge was easily caused by filter blockage.

[0015] This utility model, by setting up a first ring frame, a second ring frame, a stainless steel wire mesh, and filter cotton, allows for easy replacement of filter media when the filter cotton becomes clogged. Simply unscrew the wing nut, remove the second ring frame, replace the filter cotton, and then reinstall the second ring frame. This makes replacing the filter media much more convenient than replacing the air intake filter that comes with the air compressor system. Overall, it saves time, effort, and costs, and also extends the service life of the air intake filter.

[0016] This utility model greatly reduces the difficulty of installation during construction by setting a corrugated hose, with port two of the corrugated hose connected to the air inlet duct. It is also convenient for later modification and maintenance. Furthermore, the position of port one can be changed at will according to the bending of the corrugated hose, making it convenient for air intake, unlike fixed air inlet ducts.
