Description

Technical Field

[0001] The present application relates to the field of air filtration, and in particular to an air filter element device for an air compressor. Background Art

[0002] Currently, in oxygen production equipment, air compressors are often needed to compress air and supply it into the oxygen production equipment. The oxygen is then prepared through subsequent cooling, drying, adsorption, output and purification operations and finally stored in gas tanks.

[0003] Since there are a lot of dust and impurities floating in the air in the natural state, if the impurities are not filtered and adsorbed, they will accumulate in the subsequent air compressor, further affecting the efficiency of the air compressor, and more seriously, may cause irreversible damage to the air compressor. Therefore, when using an air compressor, an air filter element is usually added at the inlet of the air compressor to adsorb dust and impurities in the air.

[0004] Regarding the above-mentioned related technologies, in order to meet the amount of compressed air required by the oxygen production equipment in actual production, multiple air compressors are usually selectively enabled to increase the air intake. When the operator performs maintenance on the air compressor filter element later, the operator needs to check and remove each filter element one by one. In order to make the overall distribution more uniform and reasonable, the air compressor is usually evenly distributed on both sides, so the operator needs to check and replace them on both sides of the machine respectively. Utility Model Content

[0005] In order to enable operators to more intuitively observe the status of air filter elements of multiple air compressors on the same oxygen generator and to quickly remove and replace the filter elements, the present application provides an air filter element device for an air compressor.

[0006] The present application provides an air filter element device for an air compressor, which adopts the following technical solution:

[0007] An air filter element device for an air compressor comprises a shell, wherein a plurality of air filters are arranged in the shell, the shell is provided with air pipes corresponding to the air filters one by one, a sealing disk for connecting the air pipe and the air filter is arranged inside the shell, one end of the sealing disk is abutted against the sealing disk, an air flow channel for connecting the air pipe and the inner side of the air filter is arranged in the middle of the sealing disk, a quick-release assembly for connecting the air filter element to the air pipe is arranged on the inner wall of the shell, and a hatch is arranged on one side of the shell.

[0008] By adopting the above technical solution, a number of air filters are placed inside the housing. The air filters are fixed to the inner wall of the housing through a fixing component, and the air filters are corresponded to the air pipes one by one. When the operator only needs to regularly observe the state of the filters inside the housing to judge whether the filters need to be replaced, and the operator can conveniently install and disassemble the air filters through a quick-release component, realizing the unified management of the air filters of multiple air compressors in the same oxygen generator.

[0009] Optionally, the quick-release component includes a sliding seat. A sliding groove is provided on the inner wall of the housing. The sliding seat is slidably connected to the inner wall of the sliding groove. The sliding direction of the sliding seat is the length direction of the air filter. The sliding seat is provided with a self-locking component. The sliding seat is provided with a support platform for placing the air filter, and the support platform faces the sealing disc.

[0010] By adopting the above technical solution, when disassembling the air filter by using the quick-release component, the operator loosens the self-locking component and slides the sliding seat along the sliding groove, thereby driving the air filter on the support platform to move and separating the air filter from the sealing disc. At this time, the operator can easily remove the air filter and replace it with a new one. The operator does not need to fix the air filter by traditional fixing methods such as tightening screws, effectively accelerating the replacement speed of the air filter by the operator.

[0011] Optionally, both the sealing disc and the support platform are provided with a sealing ring group. The sealing ring group is located on the side where the sealing disc and the support platform are close to each other. The sealing ring group includes two circles of sealing rings, and a sealing groove for placing the air filter is provided between the two circles of sealing rings.

[0012] By adopting the above technical solution, when the air filter is placed on the support platform and installed, the two sealing ring groups of the sealing disc and the support platform limit the air filter core, and at the same time seal the axial direction of the air filter, so that the air entering the air pipe enters the air filter from the axial direction of the air filter, effectively improving the filtering accuracy of the air.

[0013] Optionally, the self-locking component includes a locking rod. The locking rods are located on both sides of the sliding seat. A plurality of jacks are provided on both sides of the sliding groove, and the jacks are arranged along the length direction of the sliding groove.

[0014] By adopting the above technical solution, after the position of the sliding seat is adjusted, the operator inserts the locking rod into the corresponding jack to fix the air filter. Since a number of jacks are arranged in sequence, the operator can select air filters of different lengths for installation, effectively realizing the fixation of the air filter and adapting to air filters of different lengths.

[0015] Optionally, the support platform is hinged to the sliding seat. The support platform rotates along the direction of approaching and departing from the hatch. A limiting block is provided on the side of the sliding seat close to the hatch, and the limiting block extends towards the sliding seat.

[0016] By adopting the above technical solution, when the operator disassembles the air filter element, the sliding seat is moved away from the sealing disc. After the air filter element is completely separated from the sealing ring group on the sealing disc, the operator rotates the supporting platform towards the hatch until the limiting block abuts against the lower side of the sliding seat. At this time, the axis of the air filter element is inclined, which is convenient for the operator to take out the air filter element and effectively facilitates the operator to replace the air filter element.

[0017] Optionally, the housing further includes an air intake grille, and a preliminary filter screen is provided on the side of the air intake grille close to the inside of the housing, and the preliminary filter screen is clamped with the inner wall of the housing.

[0018] By adopting the above technical solution, a preliminary filter screen is provided at the air intake grille to block and isolate larger dust particles in the air, thereby reducing the large particle dust entering the interior, and effectively extending the service life of the air filter element inside the housing.

[0019] Optionally, a buckle for fixing the housing is provided on the outer side of the housing, and the buckle is adapted to the outer shell of the air tank.

[0020] By adopting the above technical solution, the outer shell of the air tank has a number of slender slits, and the housing is fixed by connecting the buckle with the slender slits, effectively reducing the number of additional installation parts required while fixing the housing.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. A number of air filter elements are placed inside the housing, and the air filter elements are fixed to the inner wall of the housing through the fixing components, and the air filter elements are corresponding to the air pipes one by one. When the operator only needs to regularly observe the state of the filter elements inside the housing to judge whether the filter elements need to be replaced, and the operator can conveniently install and disassemble the air filter elements through the quick-release components, realizing the unified management of the air filter elements of multiple air compressors in the same oxygen generator.

[0023] 2. When disassembling the air filter element using the quick-release component, the operator loosens the self-locking component and slides the sliding seat along the chute, thereby driving the air filter element on the supporting platform to move, separating the air filter element from the sealing disc. At this time, the operator can easily remove the air filter element and replace it with a new one. The operator does not need to fix the air filter element by traditional fixing methods such as tightening screws, effectively accelerating the replacement speed of the air filter element by the operator.

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] The embodiment of the present application discloses an air filter element device for an air compressor.

[0032] Embodiment 1:

[0033] Reference Figures 1 to 4 An air filter element device for an air compressor includes a housing 1, a plurality of air filters 2 are arranged in the housing 1, an air supply pipe 12 corresponding to the air filters 2 is arranged in the housing 1, a sealing disc 3 for connecting the air supply pipe 12 and the air filter 2 is arranged in the housing 1, one end of the sealing disc 3 is in contact with the sealing disc 3, an air flow channel for connecting the air supply pipe 12 and the inside of the air filter 2 is arranged in the middle of the sealing disc 3, a quick-release assembly for connecting the air filter 2 and the air supply pipe 12 is arranged on the inner wall of the housing 1, and a hatch 11 is arranged on one side of the housing 1. A plurality of air filters 2 are placed in the housing 1, the air filter 2 is fixed to the inner wall of the housing 1 by a fixing assembly, and the air filter 2 corresponds to the air supply pipe 12 one by one. When the operator only needs to regularly observe the state of the filter element in the housing 1 to determine whether the filter element needs to be replaced, and the operator can install and remove the air filter element 2 more conveniently through the quick-release assembly, the air filter elements 2 of multiple air compressors in the same oxygen concentrator are managed uniformly.

[0034] To facilitate the removal and replacement of the air filter element 2 by the operator, this embodiment provides a quick-release assembly. The quick-release assembly includes a sliding seat 5. A sliding groove 14 is provided on the inner wall of the housing 1. The sliding seat 5 is slidably connected to the inner wall of the sliding groove 14. The sliding direction of the sliding seat 5 is the length direction of the air filter element 2. The sliding seat 5 is provided with a self-locking assembly. The sliding seat 5 is provided with a support table 4 for placing the air filter element 2. The support table 4 faces the sealing disc 3. When disassembling the air filter element 2 using the quick-release assembly, the operator loosens the self-locking assembly and slides the sliding seat 5 along the sliding groove 14, thereby driving the air filter element 2 on the support table 4 to move and separating the air filter element 2 from the sealing disc 3. At this time, the operator can easily remove the air filter element 2 and replace it with a new one. The operator does not need to fix the air filter element 2 by traditional fixing methods such as tightening screws, which speeds up the replacement speed of the air filter element 2 by the operator.

[0035] When the air filter element 2 is in normal use, air usually enters the air filter element 2 through the circumference of the air filter element 2 and enters the rear air duct 12 through the axial space inside the air filter element 2. If the sealing degree at both ends of the air filter element 2 is insufficient, impurities will enter the air duct 12 from the gap, affecting the subsequent steps. Both the sealing disc 3 and the support table 4 are provided with a sealing ring group 41. The sealing ring group 41 is located on the side where the sealing disc 3 and the support table 4 are close to each other. The sealing ring group 41 includes two circles of sealing rings, and a sealing groove for placing the air filter element 2 is provided between the two circles of sealing rings. When the air filter element 2 is placed on the support table 4 and the installation is completed, the two sealing ring groups 41 of the sealing disc 3 and the support table 4 limit the core of the air filter element 2. At the same time, the axis of the air filter element 2 is sealed, so that the air entering the air duct 12 all enters the inside of the air filter element 2 axially, improving the filtering accuracy of the air.

[0036] This embodiment provides a self-locking assembly with a relatively simple structure. The self-locking assembly includes a locking rod 6. The locking rod 6 is located on both sides of the sliding seat 5. A jack is provided on both sides of the sliding groove 14, and a number of jacks are provided along the length direction of the sliding groove 14. After the position adjustment of the sliding seat 5 is completed, the operator inserts the locking rod 6 into the corresponding jack to fix the air filter element 2. Since a number of jacks are provided in sequence, the operator can select air filter elements 2 of different lengths for installation, effectively realizing the fixation of the air filter element 2 and adapting to air filter elements 2 of different lengths.

[0037] To further reduce the loss and maintenance frequency of the air filter element 2. The housing 1 further includes an air intake grille. A preliminary filter screen 15 is provided on the side of the air intake grille close to the inside of the housing 1. The preliminary filter screen 15 is snap-connected to the inner wall of the housing 1. The preliminary filter screen 15 is provided at the air intake grille to block and isolate larger dust particles in the air, thereby reducing the large particle dust entering the interior, and effectively extending the service life of the air filter element 2 inside the housing 1.

[0038] In order to rationally utilize the slit outside the inner gas tank 101 of the oxygen generator to install the housing 1. A buckle 13 for fixing the housing 1 is provided on the outside of the housing 1, and the buckle 13 is adapted to the outer shell of the gas tank 101. The outer shell of the gas tank 101 has a number of slender slits, and the housing 1 is fixed by connecting the buckle 13 with the slender slits, effectively reducing the number of additional installation parts required while fixing the housing 1.

[0039] Embodiment 2:

[0040] Refer to Figure 2 And Figure 5 . The biggest difference between this embodiment and Embodiment 1 is that the support table 4 is hinged to the sliding seat 5, the support table 4 rotates along the direction of approaching and departing from the hatch 11, and a limiting block 51 is provided on the side of the sliding seat 5 close to the hatch 11, and the limiting block 51 extends towards the sliding seat 5. When the operator disassembles the air filter element 2, the sliding seat 5 is moved in the direction away from the sealing disc 3. When the air filter element 2 is completely separated from the sealing ring group 41 on the sealing disc 3, the operator rotates the support table 4 towards the hatch 11 until the limiting block 51 abuts against the lower side of the sliding seat 5. At this time, the axis of the air filter element 2 is inclined, so as to facilitate the operator to take out the air filter element 2, effectively facilitating the operator to replace the air filter element 2.

[0041] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
