Description

TECHNICAL FIELD

[0001] The utility model relates to the field of air filter, concretely to a three filter cartridge connected air filter assembly. BACKGROUND

[0002] In today's industrial production, air quality has a crucial influence on the normal operation and service life of equipment. If the particulate matters such as dust and impurities contained in the air enter the equipment, it will exacerbate the wear and tear of parts, reduce the performance of the equipment, and even cause failure. Therefore, air filtration equipment has become an indispensable part of many devices.

[0003] In practical application, the traditional air filter is usually designed with a single filter cartridge. The filtering area of this design is limited, which cannot meet the needs of some equipment that requires high air quality or has large air flow. With the increasing complexity of the operating environment of the equipment and the increasing demand for air filtration effect, the filtering efficiency of the single filter cartridge gradually appears to be inadequate. It cannot effectively filter the fine particles in the air, resulting in a certain degree of pollution inside the equipment. In the overall structural design of the air filter, the traditional products also have many shortcomings. The layout of the air inlet pipe and the air outlet pipe of some air filters is unreasonable, and the position and angle of the air inlet pipe are improper, which can easily cause external water and impurities to flow directly into the air filter, causing damage to the filter element, and thus affecting the filtering effect and the service life of the air filter. If the design of the air outlet pipe cannot be well matched with the subsequent pipeline, it will cause poor air delivery, increase air resistance, and reduce the overall operating efficiency of the equipment. In addition, the assembly and maintenance convenience of the traditional air filter is poor. The connection method of the upper and lower shells of some air filters is complex, and it is difficult to operate when the internal filter element needs to be replaced or repaired, which consumes a lot of time and labor cost. Moreover, the fixing method of the filter element in the shell is not stable enough, and the filter element is prone to displacement during the operation of the equipment due to factors such as vibration, which affects the stability and reliability of the filtration.

[0004] In view of the above problems of the traditional air filter, the market urgently needs a new air filter product to solve these pain points. It is necessary to improve the air filtration efficiency, enhance the stability and reliability of the air filter, and reduce the maintenance cost to meet the higher requirements of modern industrial production and various mechanical equipment for air filtration. INVENTION CONTENTS

[0005] The utility model aims at providing a three filter cartridge connected air filter assembly, which makes the external air enter the air barrel-shaped lower shell through the air inlet pipe inclined upward, fully contacts and filters with the three filter cartridge connected filter element, the clamping block and the recess of the lower shell cooperate with the filter element to fix, the upper and lower shells are connected through clamping and thread hole to ensure the sealing property, the clean air after filtration is discharged from the horizontal air outlet pipe at the top of the upper shell, and the filter element top stable disc is clamped with the inner cavity of the upper shell to ensure the stability of the filter element.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] A three-filter-cylinder connected air filter assembly, comprising a lower shell. The lower shell is an open-top air barrel, which maximizes the accommodation of filter cartridges in limited space and provides a reasonable spatial layout for air flow. An air inlet pipe is arranged obliquely upward on one side of the lower shell. The oblique upward design can avoid water or debris flowing directly into the air filter interior along the air inlet pipe under certain working conditions, thereby preventing damage to the filter cartridges. The air inlet pipe is in communication with the interior of the lower shell. This design ensures that external air can smoothly enter the interior of the lower shell through the air inlet pipe and then fully contact the filter cartridges for filtration.

[0008] The lower shell is provided with an empty chamber for matching and clamping the filter cartridges. The clamping mode of the empty chamber and the filter cartridges facilitates the installation and removal of the filter cartridges and is convenient for maintenance and replacement in the later period.

[0009] The lower shell is provided with an open top for matching and clamping an upper shell. This structure of the upper and lower shells clamped together makes the assembly and disassembly of the entire air filter assembly more convenient and facilitates the inspection and repair of the internal components. An air outlet pipe is arranged horizontally on the top of the upper shell. The horizontal air outlet pipe design is conducive to the connection with subsequent pipelines. The air outlet pipe is in communication with the interior of the lower shell, which ensures that the clean air filtered by the filter cartridges can smoothly pass through the air outlet pipe of the upper shell from the lower shell, thereby completing the entire air filtration process.

[0010] The filter cartridges are three-filter-cylinder connected filter cartridges. Compared with a single filter cartridge, this three-filter-cylinder connected design can provide a larger filtration area in the same space and improve the filtration efficiency. The lower shell is inwardly recessed, and the recess is embedded with the filter cartridges. This recess and embedding design further enhances the stability of the filter cartridges after installation, making the cooperation between the filter cartridges and the lower shell more compact and avoiding the shaking of the filter cartridges during air flow, which affects the filtration effect.

[0011] The inner side of the lower shell and the air inlet pipe are provided with clamping blocks, which face outward. The clamping blocks are mainly arranged to better position and fix the filter cartridges during installation, thereby ensuring the accuracy and firmness of the installation of the filter cartridges. The number of clamping blocks is 3 or more. The design of multiple clamping blocks can fix the filter cartridges from multiple directions, so that the filter cartridges can remain stable in different directions. The clamping blocks are in the same plane, which ensures that the force of each clamping block on the filter cartridges is more uniform during the fixation of the filter cartridges, thereby avoiding deformation or damage of the filter cartridges due to uneven force.

[0012] The relative screw holes are arranged at the clamping position of the lower shell and the upper shell, so that the lower shell and the upper shell can be further fastened by bolts or other connecting members after clamping, the stability of the connection between the upper shell and the lower shell is enhanced, the separation of the upper shell and the lower shell caused by vibration or the like during the working process of the air filter assembly is avoided, and the sealing performance and reliability of the air filter are ensured.

[0013] The stable disc is fixedly installed at the top of the filter element, and the stable disc serves to further stabilize the position of the filter element.

[0014] During the working process, the external air firstly enters the air barrel-shaped lower shell with a top opening along the air inlet pipe which is inclined upward, so that the water and sundries are prevented from flowing directly into the air inlet pipe. The air in the lower shell is in full contact with the three-filter-cylinder integrated filter element, the three-filter-cylinder integrated design increases the filtering area and improves the filtering efficiency. The air cleaned by the filter element is discharged through the air outlet pipe which is internally arranged in the lower shell and horizontally arranged at the top of the upper shell, so as to be conveniently connected with the subsequent pipeline. The lower shell and the upper shell are fastened and connected through clamping and relative screw holes, so as to ensure the sealing performance. The stable disc at the top of the filter element is clamped with the inner cavity of the upper shell, so as to fix the filter element in all directions and ensure that the filter element is not displaced by the air flow impact force during the working process, thereby ensuring that the whole air filtering process is stable and efficient.

[0015] Compared with the prior art, the air filter has the following beneficial effects:

[0016] The lower shell is in the form of an air barrel with a top opening, and the air inlet pipe is arranged on one side and inclined upward, so that the water and sundries are prevented from flowing directly into the air inlet pipe, and reasonable space layout is provided for air flow. The upper shell and the lower shell are clamped and connected through relative screw holes at the clamping position, so that the air filter is convenient to assemble and disassemble, the connection stability is enhanced, and the internal components are convenient to maintain and check.

[0017] Adopt three filter cartridge connected filter core, compared with single filter cartridge, provide greater filter area in the same space, improve the filtering efficiency; The lower shell is recessed inward and embedded with the filter core, cooperates with the inside shell and the multiple clamping blocks on the air inlet pipe in the same plane, and the stable disc on the top of the filter core and the inner cavity of the upper shell, and the filter core is stable from multiple directions and positions, ensures that the position of the filter core is stable during work, is not affected by air flow impact, guarantees the reliability and continuity of the filtering effect, reduces the number of parts, simplifies the structure, and reduces the manufacturing cost.

[0018] The upper shell is provided with an air outlet pipe at the top, which is communicated with the inside of the lower shell, which is beneficial to the connection with the subsequent pipeline, ensures that the filtered air can be smoothly transported, and meets the use demand.

[0024] As Figs. 1-3 shown, a three-filter-cartridge-connected air filter assembly, comprising a lower shell 1, characterized in that the lower shell 1 is an open-top air barrel, one side of which is provided with an air inlet pipe 11 inclined upward, the air inlet pipe 11 is communicated with the inside of the lower shell 1, the lower shell 1 is matched with a filter core 2 in the cavity, the top of the lower shell 1 is matched with an upper shell 3, the upper shell 3 is provided with an air outlet pipe 31 in the horizontal direction at the top, and the air outlet pipe 31 is communicated with the inside of the lower shell 3.

[0025] The filter core 2 is a three-filter-cartridge-connected filter core, and the lower shell 1 is recessed inward.

[0026] The inside shell of the lower shell 1 is provided with a clamping block 12 on the air inlet pipe 11, and the clamping block 12 faces outward,

[0027] The number of clamping blocks 12 is three or more than three, and the clamping blocks 12 are in the same plane.

[0028] The lower shell 1 and the upper shell 3 are connected by a thread hole.

[0029] The filter core 2 is fixedly installed with a stable disc 21 at the top, which is engaged with the internal cavity of the upper shell 3.

[0030] When the three-filter-cylinder-connected air filter assembly is working, the external air first enters the open-top air barrel-shaped lower shell 1 through the obliquely upward air inlet pipe 11, which is connected with the inside of the lower shell 1. The oblique design can effectively prevent water and sundries from easily flowing in. The air entering the lower shell 1 will be in full contact with the three-filter-cylinder-connected filter core 2, starting the air filtering process.
