Description

Technical Field

[0001] This application relates to the field of filter technology, and more particularly to an air filter. Background Technology

[0002] An air filter, as the name suggests, is a device used to filter out moisture, dust, or other impurities from the air, thus purifying the air. It is typically used in spaces that require dust and pollution protection.

[0003] While conventional filters can remove airborne particles, poorly designed airflow paths often result in low filtration efficiency, affecting air purification quality. Furthermore, for some spaces with stringent requirements, sterile air is needed, and existing conventional filters cannot meet these high demands.

[0004] Therefore, this application provides an air filter. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an air filter that overcomes these deficiencies. It aims to solve the problem that while conventional filters can remove airborne particles, their poorly designed airflow paths often result in low filtration efficiency, affecting air purification quality. Furthermore, for some spaces with stringent requirements, sterile air is needed, and existing conventional filters cannot meet these high-demand conditions.

[0006] To achieve the above objectives, this application provides the following technical solution: an air filter, comprising a housing, wherein a filter channel is fixedly installed inside the housing, the filter channel being S-shaped, an air inlet pipe is fixedly connected to the air inlet end of the filter channel, an air outlet pipe is fixedly connected to the air outlet end of the filter channel, and a plurality of connecting mechanisms are provided inside the filter channel, wherein composite coarse filter material, composite fine filter material, and composite alumina filter material are respectively connected to the filter channel through the plurality of connecting mechanisms, wherein the pore size of the composite coarse filter material is larger than that of the composite fine filter material, and the composite coarse filter material, composite fine filter material, and composite alumina filter material are uniformly arranged from the air inlet end to the air outlet end of the filter channel, wherein an electrostatic adsorption layer is installed inside the filter channel on one side of the composite alumina filter material, and a composite activated carbon layer is installed inside the filter channel on one side of the electrostatic adsorption layer, wherein the composite activated carbon layer is located on the side of the electrostatic adsorption layer away from the composite alumina filter material, and connecting mechanisms are provided at the connection points between the electrostatic adsorption layer and the composite activated carbon layer and the filter channel.

[0007] By adopting the above technical solution, when air enters the filtration channel from the air inlet duct, it first passes through the composite coarse filter material, which is composed of several groups of polyphenylene sulfide layers, effectively intercepting large particles in the air. Then, the air enters the composite fine filter material, which is made of several groups of glass fiber layers and other ultra-fine fibers, capable of filtering out fine particles. Next, the air passes through the composite alumina filter material, a nano-scale filter material with ultra-small pores, intercepting tiny particles. Then, the air passes through the electrostatic adsorption layer for further electrostatic adsorption of impurities. Finally, it passes through the composite activated carbon layer for sterilization and odor removal before being discharged through the exhaust duct, making the air purer. The electrostatic adsorption layer adsorbs fine particles from the air, and the S-shaped filtration channel increases the contact time between the air and the filter material within the filtration channel. Combined with the fact that the composite coarse filter material, composite fine filter material, composite alumina filter material, and electrostatic adsorption layer are all multi-layered composite materials, multi-stage filtration is beneficial for better filtering of impurities in the air and improving the purity of the filtered air.

[0008] As a preferred technical solution of this application, the connecting mechanism includes two sets of sliding plates, which are respectively fixedly installed on both sides of the composite coarse filter material, composite fine filter material, or composite alumina filter material. The inner wall of the filter channel is provided with several sets of sliding grooves, and the sliding plates are slidably connected to the sliding grooves.

[0009] By adopting the above technical solution, the composite coarse filter material, composite fine filter material, or composite alumina filter material can all be separated from the filter channel by sliding out of the slide groove through the sliding plates on both sides. The connecting mechanism facilitates the disassembly and replacement of the composite coarse filter material, composite fine filter material, or composite alumina filter material, which is beneficial to the convenience of maintenance and cleaning.

[0010] As a preferred technical solution of this application, an air quality detector is fixedly installed inside the exhaust pipe, and a signal device is placed inside the air quality detector.

[0011] By adopting the above technical solution, the air quality detector can monitor the air quality discharged from the exhaust duct in real time to ensure the filtration effect. Once a decline in filtration effect is detected, the signal is transmitted to the control terminal through the built-in signal device of the air quality detector, which can promptly remind staff to clean or replace the filter material inside the filter channel, thus helping to ensure the filtration effect.

[0012] As a preferred technical solution of this application, both the air inlet pipe and the air outlet pipe are equipped with metal mesh. The metal mesh includes several sets of metal strips, which are evenly distributed along the inside of the air inlet pipe or the air outlet pipe, and the metal strips are wavy.

[0013] By adopting the above technical solution, the wavy shape of the metal strip can guide the airflow to enter the air inlet pipe and exit the air outlet pipe more evenly, avoiding situations where the local airflow is too large or too small. At the same time, it helps to reduce the noise generated when the air passes through, thus improving the noise reduction effect of the device.

[0014] As a preferred technical solution of this application, a heat dissipation cavity is provided inside the housing on the outer periphery of the filter channel, and several sets of heat dissipation meshes are fixedly installed at both the upper and lower ends of the housing.

[0015] By adopting the above technical solution, when the housing is installed in a high-temperature environment, the heat dissipation cavity and heat dissipation mesh help to reduce the temperature of the filter channel during operation, thereby reducing the impact of the high-temperature environment on the housing and improving the high-temperature protection effect of the housing.

[0016] As a preferred technical solution of this application, a number of heat dissipation fins are fixedly installed on the outer wall of the filter channel.

[0017] By adopting the above technical solution, the heat dissipation area of ​​the filter channel is increased by several sets of heat dissipation fins, thereby improving the heat dissipation efficiency of the filter channel and effectively reducing the possibility of high-temperature deformation of the outer shell and filter channel.

[0018] As a preferred technical solution of this application, sealing strips are fixedly installed on the outer rings of both the air inlet pipe and the air outlet pipe.

[0019] By adopting the above technical solution, the air inlet pipe and the air outlet pipe are connected to two sets of external air ducts respectively, and the sealing strip improves the sealing performance when the air inlet pipe and the air outlet pipe are connected to the external air ducts, thereby improving the sealing performance of this device.

[0020] As a preferred technical solution of this application, a cover plate is provided on the front surface of the outer shell, and a special-shaped plate is fixedly connected to the middle of the cover plate. The special-shaped plate is adapted to the filter channel, and bolts are threadedly connected to the four corners of the cover plate and the connection between the cover plate and the outer shell.

[0021] By adopting the above technical solution, both the cover plate and the irregular plate are connected to the outer shell by bolts, which facilitates the installation and disassembly of the components inside the outer shell and improves work efficiency.

[0022] The beneficial effects of this application are:

[0023] 1. When air enters the filtration channel from the air inlet duct, it first passes through the composite coarse filter material, which consists of several layers of polyphenylene sulfide (PPS) to effectively intercept large particles in the air. Next, the air enters the composite fine filter material, which is made of several layers of ultra-fine fibers such as glass fiber to filter out fine particles. Then, the air passes through the composite alumina filter material, a nano-scale filter material with ultra-small pores that intercepts tiny particles. Afterward, the air passes through the electrostatic adsorption layer for further electrostatic adsorption of impurities. Finally, it passes through the composite activated carbon layer for sterilization and odor removal before being discharged through the exhaust duct, resulting in purer air. The electrostatic adsorption layer removes fine particles from the air, and the S-shaped filtration channel increases the contact time between the air and the filter material. Combined with the fact that the composite coarse filter material, composite fine filter material, composite alumina filter material, and electrostatic adsorption layer are all multi-layered composite materials, this multi-stage filtration helps to better filter impurities in the air and improves the purity of the filtered air.

The composite coarse filter media, composite fine filter media, or composite alumina filter media are separated from the filter channel by sliding out of the slide groove through the sliding plates on both sides. The connecting mechanism facilitates the disassembly and replacement of the composite coarse filter media, composite fine filter media, or composite alumina filter media, which is beneficial to the convenience of maintenance and cleaning.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 An air filter includes a housing 1, inside which a filter channel 2 is fixedly installed. The filter channel 2 is S-shaped. An air inlet pipe 201 is fixedly connected to the air inlet end of the filter channel 2, and an air outlet pipe 202 is fixedly connected to the air outlet end of the filter channel 2. Several sets of connecting mechanisms 7 are provided inside the filter channel 2. Composite coarse filter material 3, composite fine filter material 4, and composite alumina filter material 5 are respectively connected to the filter channel 2 through the several sets of connecting mechanisms 7. The pore size of the composite coarse filter material 3 is larger than that of the composite fine filter material 4. The filter material 5 is evenly arranged from the air inlet to the air outlet of the filter channel 2. An electrostatic adsorption layer 6 is installed inside the filter channel 2 on one side of the composite alumina filter material 5. A composite activated carbon layer 8 is installed inside the filter channel 2 on one side of the electrostatic adsorption layer 6. The composite activated carbon layer 8 is located on the side of the electrostatic adsorption layer 6 away from the composite alumina filter material 5. A connecting mechanism 7 is provided at the connection between the electrostatic adsorption layer 6 and the composite activated carbon layer 8 and the filter channel 2. An air quality detector 17 is fixedly installed inside the exhaust pipe 202. An indicator is placed inside the air quality detector 17.

[0032] When air enters the filter channel 2 from the air inlet duct 201, it first passes through the composite coarse filter material 3, which is composed of several layers of polyphenylene sulfide (PPS) to effectively intercept large particles in the air. Then, the air enters the composite fine filter material 4, which is made of several layers of glass fiber and other ultra-fine fibers to filter out fine particles. Next, the air passes through the composite alumina filter material 5, a nano-scale filter material with ultra-small pores that intercepts tiny particles. Then, the air passes through the electrostatic adsorption layer 6 for further electrostatic adsorption of impurities. Finally, it passes through the composite activated carbon layer 8 for sterilization and odor removal before being discharged through the exhaust duct 202, resulting in cleaner air. For fine particulate matter in the air, the S-shaped filter channel 2 increases the contact time between the air and the filter material inside the filter channel 2. Combined with the multi-layered composite coarse filter material 3, composite fine filter material 4, composite alumina filter material 5, and electrostatic adsorption layer 6, this multi-stage filtration effectively removes impurities from the air and improves the purity of the filtered air. The air quality detector 17 monitors the air quality discharged from the exhaust duct 202 in real time to ensure filtration effectiveness. If a decline in filtration efficiency is detected, the signal from the built-in signal generator in the air quality detector 17 is transmitted to the control terminal, prompting staff to promptly clean or replace the filter material inside the filter channel 2, thus ensuring optimal filtration performance.

[0033] Reference Figure 1 The connecting mechanism 7 includes two sets of sliding plates 701, which are fixedly installed on both sides of the composite coarse filter material 3, composite fine filter material 4, or composite alumina filter material 5. The inner wall of the filter channel 2 is provided with several sets of sliding grooves 702, and the sliding plates 701 are slidably connected to the sliding grooves 702. The inside of the air inlet pipe 201 and the air outlet pipe 202 are both equipped with metal mesh 12. The metal mesh 12 includes several sets of metal strips 1201, which are evenly distributed along the inside of the air inlet pipe 201 or the air outlet pipe 202, and the metal strips 1201 are wavy.

[0034] The composite coarse filter material 3, composite fine filter material 4, or composite alumina filter material 5 are all separated from the filter channel 2 by sliding out of the slide groove 702 through the sliding plates 701 on both sides. The connecting mechanism 7 facilitates the disassembly and replacement of the composite coarse filter material 3, composite fine filter material 4, or composite alumina filter material 5, which is beneficial to the convenience of maintenance and cleaning. The wavy shape of the metal strip 1201 can guide the airflow to enter the air inlet pipe 201 and exit the air outlet pipe 202 more evenly, avoiding the situation of excessive or insufficient local airflow. At the same time, it helps to reduce the noise generated when the air passes through, thus improving the noise reduction effect of this device.

[0035] Reference Figure 1-3The outer casing 1 has a heat dissipation cavity 9 located around the outer periphery of the filter channel 2. Several sets of heat dissipation meshes 10 are fixedly installed at both the upper and lower ends of the outer casing 1. Sealing strips 13 are fixedly installed on the outer rings of the air inlet pipe 201 and the air outlet pipe 202. When the outer casing 1 is installed in a high-temperature environment, the heat dissipation cavity 9 and the heat dissipation meshes 10 help to reduce the temperature of the filter channel 2 during operation, thereby reducing the impact of the high-temperature environment on the outer casing 1 and improving the high-temperature protection effect of the outer casing 1. The air inlet pipe 201 and the air outlet pipe 202 are respectively connected to two sets of external air ducts. The sealing strips 13 improve the sealing performance when the air inlet pipe 201 and the air outlet pipe 202 are connected to the external air ducts, thereby improving the sealing performance of this device.

[0036] Reference Figure 1-3 Several sets of heat dissipation fins 11 are fixedly installed on the outer wall of the filter channel 2; a cover plate 14 is provided on the front surface of the outer shell 1, and a special-shaped plate 15 is fixedly connected to the middle of the cover plate 14. The special-shaped plate 15 is adapted to the filter channel 2, and bolts 16 are threadedly connected to the four corners of the cover plate 14 and the outer shell 1; the heat dissipation area of ​​the filter channel 2 is increased by several sets of heat dissipation fins 11, thereby improving the heat dissipation efficiency of the filter channel 2 and effectively reducing the possibility of high-temperature deformation of the outer shell 1 and the filter channel 2; the cover plate 14 and the special-shaped plate 15 are both connected to the outer shell 1 by bolts 16, which is conducive to the installation and disassembly of the components inside the outer shell 1 and improves work efficiency.

[0037] Working principle: When air enters the filter channel 2 from the air inlet duct 201, it first passes through the composite coarse filter material 3, which is composed of several groups of polyphenylene sulfide layers, effectively intercepting large particles in the air. Then, the air enters the composite fine filter material 4, which is made of several groups of ultra-fine fibers such as glass fiber layers, capable of filtering out fine particles. Next, the air passes through the composite alumina filter material 5, which is a nano-scale filter material with ultra-small pores, intercepting tiny particles. Then, the air passes through the electrostatic adsorption layer 6 for electrostatic adsorption of impurities. Finally, it passes through the composite activated carbon layer 8 for sterilization. After removing odors, the exhaust pipe 202 is used to make the air purer. Fine particulate matter in the air is adsorbed by the electrostatic adsorption layer 6. The filter channel 2 is S-shaped, which increases the contact time between the air and the filter material in the filter channel 2. The composite coarse filter material 3, composite fine filter material 4, composite alumina filter material 5 and electrostatic adsorption layer 6 are all multi-layer composite materials, which can perform multi-stage filtration, which is conducive to better filtering impurities in the air and improving the purity of the filtered air. The composite coarse filter material 3, composite fine filter material 4 or composite alumina filter material 5 are all separated from the filter channel 2 by sliding out of the slide groove 702 through the slide plates 701 on both sides.

[0038] Among them, the air quality detector 17 can monitor the air quality discharged from the exhaust pipe 202 in real time. Once the filtration effect is detected to be reduced, the signal is transmitted to the control terminal through the built-in signal of the air quality detector 17. The metal strip 1201 is wavy, which can guide the airflow to enter the air inlet pipe 201 and exit the exhaust pipe 202 more evenly.

[0039] Meanwhile, when the outer casing 1 is installed in a high-temperature environment, the heat dissipation cavity 9 and heat dissipation mesh 10 help to reduce the temperature of the filter channel 2 during operation; the heat dissipation area of ​​the filter channel 2 is increased by several sets of heat dissipation fins 11, thereby improving the heat dissipation efficiency of the filter channel 2.

[0040] In addition, the air inlet pipe 201 and the air outlet pipe 202 are respectively connected to two sets of external air ducts. The sealing strip 13 improves the sealing performance when the air inlet pipe 201 and the air outlet pipe 202 are connected to the external air ducts. The cover plate 14 and the special-shaped plate 15 are both connected to the outer shell 1 by bolts 16, which facilitates the installation and disassembly of the components inside the outer shell 1.
