Description

Technical Field

[0001] This application relates to the field of filter technology, and in particular to a coalescing filter. Background Technology

[0002] A coalescing filter cartridge is a filtration device that uses coalescing material as the medium and is the main component in a coalescer that performs the filtration function. Tiny oil droplets dispersed in liquids such as water are captured by the ultrafine fibers on the surface of the oleophilic filter media and coalesce to form larger oil droplets. Since the density of oil droplets is less than that of water, the coalesced oil droplets automatically float to the top of the coalescer and flow out from the top opening of the coalescer; water flows outward directly through the side wall of the filter media, thereby achieving the effect of oil and water separation.

[0003] In existing coalescing filter cartridges, the bonding joints of the coalescing layer are prone to delamination during use, which directly affects the filtration effect of the filter cartridge. Utility Model Content

[0004] In order to improve the problem of easy delamination of the coalescing layer in existing coalescing filter elements, this application provides a coalescing filter element.

[0005] This application provides a coalescing filter element, including a filter element assembly and a support mechanism installed inside the filter element assembly. The filter element assembly includes a filter tube, and the outer wall of the filter tube is fitted with a coalescing layer. The outer wall of the coalescing layer is fitted with a nylon mesh, and the outer wall of the filter tube has a plurality of equally spaced through holes.

[0006] By adopting the above structure, the coalescing layer on the outer wall of the filter tube facilitates gas filtration, the nylon mesh provides protection for the coalescing layer, the through holes on the filter tube allow the filtered gas to enter the filter tube, and the support mechanism provides stable support for the filter tube, thereby improving the strength of the filter tube.

[0007] The coalescing layer is formed by combining wood pulp paper and a corrugated fiber layer, both of which have a folded structure.

[0008] By adopting the above structure, the filtration effect of the coalescing layer is improved by using a multi-layer folded structure for the wood pulp paper and the fiber corrugated layer.

[0009] Both ends of the filter tube are fixedly connected with end caps.

[0010] By adopting the above structure, the filter tube can be easily sealed by setting two end caps.

[0011] The support mechanism includes a support column fixedly connected in the filter tube, and the outer wall of the support column has two symmetrically arranged grooves. Multiple support components are slidably installed on the outer wall of the support column.

[0012] By adopting the above structure, the support columns facilitate the installation of the support components, and the grooves facilitate the installation of the support components.

[0013] The support assembly includes a mounting sleeve that is slidably connected to the outer wall of the support column, and two connecting components that slide in grooves are installed on the inner wall of the mounting sleeve. Three equally spaced support frames are fixedly connected to the outer wall of the mounting sleeve.

[0014] By adopting the above structure, the support frame on the mounting sleeve can easily support the inner wall of the filter tube, and the fit between the connecting component and the groove makes it easy to fix the mounting sleeve on the support column.

[0015] The connecting assembly includes a connecting seat fixedly connected to the inner wall of the mounting sleeve, and openings are provided on both sides of the inner wall of the connecting seat. A clamping block is slidably connected to the inner wall of each of the two openings, and a wedge plate is fixedly connected to the outer wall of each of the two clamping blocks on opposite sides.

[0016] By adopting the above structure, the two wedge plates facilitate the movement of the clamping block, which presses against the inner wall of the groove, thus making it easier to fix the mounting sleeve to the support column. The wedge plates facilitate the movement of the clamping block.

[0017] The inner wall of the connecting seat is slidably connected to a trapezoidal block, and the outer wall of the trapezoidal block has two grooves. One end of each of the two wedge plates is slidably connected to the inner wall of the groove.

[0018] By adopting the above structure, the wedge plate can be easily slidably installed through the groove on the trapezoidal block, and when the trapezoidal block moves, the two clamping blocks can be directly driven to move through the wedge plate.

[0019] The outer wall of each mounting sleeve has a circular opening extending into the connecting seat, and the inner wall of each of the two circular openings is slidably connected with a pull rod. One end of each of the two pull rods is fixedly connected to two trapezoidal blocks, and the outer wall of each of the two pull rods is sleeved with a spring.

[0020] By adopting the above structure, the pull rod facilitates the direct pulling of the trapezoidal block, and the spring facilitates the driving of the trapezoidal block to always be in the lower position. When the trapezoidal block is in the lower position, it is convenient to directly drive the two clamping blocks to extend.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. This application improves the stability of the wood pulp paper bonding by setting a coalescing layer on the outer wall of the filter tube. The coalescing layer is formed by combining wood pulp paper and a corrugated fiber layer. Furthermore, a double V-shaped combination is adopted at the bonding point of the wood pulp paper, thereby changing the original double-sided bonding method to a four-sided bonding method. This solves the problem of easy delamination at the bonding point of the existing wood pulp paper.

[0023] 2. This application improves the stability of the filter element by setting a support mechanism in the filter tube, in which multiple support components facilitate auxiliary support of the filter tube, thereby avoiding deformation of the filter tube. Attached Figure Description

[0033] Reference Figure 1-2The coalescing layer 4 is formed by combining wood pulp paper and a corrugated fiber layer, and both the wood pulp paper and the corrugated fiber layer have a folded structure. Wood pulp paper refers to paper made from pulp extracted by cooking wood chips. By adopting a multi-layer folded structure for the wood pulp paper and the corrugated fiber layer in the coalescing layer 4, the filtration effect of the coalescing layer 4 is improved.

[0035] Reference Figure 3 The support mechanism 7 includes a support column 8 fixedly connected in the filter tube 2, and two symmetrically arranged grooves 9 are opened on the outer wall of the support column 8. The support column 8 is fixed at the central axis of the filter tube 2. Multiple support components 10 are slidably installed on the outer wall of the support column 8. The support column 8 facilitates the installation of the support components 10, and the grooves 9 facilitate the installation of the support components 10.

[0036] Reference Figure 3 and Figure 4 The support assembly 10 includes a mounting sleeve 11 that is slidably connected to the outer wall of the support column 8, and two connecting assemblies 12 that slide in the groove 9 are installed on the inner wall of the mounting sleeve 11. Three equally spaced support frames 13 are fixedly connected to the outer wall of the mounting sleeve 11. The support frames 13 on the mounting sleeve 11 facilitate the support of the inner wall of the filter tube 2. The cooperation between the connecting assemblies 12 and the groove 9 facilitates the fixing of the mounting sleeve 11 to the support column 8.

[0037] Reference Figure 4-5 The connecting component 12 includes a connecting seat 15 fixedly connected to the inner wall of the mounting sleeve 11, and openings are provided on both sides of the inner wall of the connecting seat 15. The two connecting components 12 are symmetrically arranged on the inner wall of the mounting sleeve 11. A clamping block 16 is slidably connected to the inner wall of each of the two openings. The clamping block 16 on the connecting seat 15 facilitates the fixing of the connecting seat 15 to the groove 9. A wedge plate 17 is fixedly connected to the outer wall of each of the two clamping blocks 16 on opposite sides. The wedge plate 17 facilitates the driving of the clamping block 16. The clamping block 16 is pressed against the inner wall of the groove 9, thereby facilitating the fixing of the mounting sleeve 11 to the support column 8. The wedge plate 17 facilitates the driving of the clamping block 16.

[0038] Reference Figure 5The inner wall of the connecting seat 15 is slidably connected to a trapezoidal block 19, and the outer wall of the trapezoidal block 19 has two sliding grooves. The two sliding grooves are symmetrically arranged on the trapezoidal block 19. One end of each of the two wedge plates 17 is slidably connected to the inner wall of the sliding groove. The wedge plates 17 can be slidably installed through the sliding grooves on the trapezoidal block 19. When the trapezoidal block 19 moves, the two clamping blocks 16 can be driven directly through the wedge plates 17.

[0039] Reference Figure 4-5 The outer wall of the mounting sleeve 11 is provided with a circular opening extending into the connecting seat 15, and the inner wall of each of the two circular openings is slidably connected with a pull rod 14. One end of each pull rod 14 is fixedly connected to a trapezoidal block 19. The pull rod 14 is designed to facilitate the direct pulling of the trapezoidal block 19. The outer wall of each pull rod 14 is fitted with a spring 18. When the trapezoidal block 19 moves, it is convenient to directly compress the spring 18. The pull rod 14 facilitates the direct pulling of the trapezoidal block 19. The spring 18 facilitates the driving of the trapezoidal block 19 to always be in the lower position. When the trapezoidal block 19 is in the lower position, it is convenient to directly drive the two clamping blocks 16 to extend.

[0040] The implementation principle of this application is as follows: During use, the nylon mesh 5 and the coalescing layer 4 on the filter element assembly 1 facilitate gas filtration. The filtered gas enters the filter tube 2 through the through hole 3 on the filter tube 2, and then is directly discharged through the end cap 6. The wood pulp paper in the coalescing layer 4 is bonded on four sides to improve the stability of the bonding. The support mechanism 7 facilitates auxiliary support for the filter tube 2, thereby improving the strength of the filter element. The multiple support components 10 in the support mechanism 7 facilitate support for multiple positions of the filter tube 2. The cooperation between the connecting component 12 and the pull rod 14 in the support component 10 facilitates adjustment of the position of the support component 10 on the support column 8. When the position of the support component 10 needs to be adjusted, the pull rod 14 is pulled first to drive the trapezoidal block 19 to compress the spring 18. When the trapezoidal block 19 compresses the spring 18, it directly drives the two clamping blocks 16 to retract into the connecting seat 15. When the connecting seat 15 is away from the inner wall of the groove 9, it facilitates the sliding of the mounting sleeve 11 on the support column 8.
