Description

TECHNICAL FIELD

[0001] The utility model relates to drying filter technical field especially easy to clean drying filter. BACKGROUND

[0002] Drying filters are critical components in many industrial applications, particularly in refrigeration, air conditioning, and heat pump systems. Their primary function is to remove moisture and impurities from refrigerants, preventing system blockage and corrosion. With technological advancements, drying filter designs and functionalities are continuously improving to enhance system efficiency and reliability.

[0003] Some drying filters have complex replacement or maintenance procedures after the drying agent is saturated or the filter screen is clogged, requiring professional operation, which results in ineffective cleaning. SUMMARY

[0004] To at least partially address the aforementioned technical problems, the utility model provides a drying filter easy to clean.

[0005] The utility model discloses the following technical scheme realizes: a drying filter easy to clean, including drying cylinder, the inside of drying cylinder is provided with air vent, the inside of drying cylinder is provided with filter plate no.

[0006] As a further improvement of the above-mentioned scheme, the drying cylinder is internally provided with an air vent, and the filter plate one is provided with two, the surface of the two filter plates one is slidably connected with the inner wall of the drying cylinder, and the handle is provided with two, the bottom end of the two handles is fixedly connected with the top end of the two filter plates one.

[0007] Through the above technical scheme, the drying cylinder serves as the shell of the entire drying filter, providing structural support and protection for the internal components, ensuring the flow path of the gas inside, and the two filter plates one help to improve the filtering and drying efficiency, serving as the first layer of filtration, intercepting larger particle impurities, effectively removing large particle impurities in the gas, and protecting subsequent filtering and drying components. The handle facilitates the installation, removal, and cleaning of the filter plate one, ensuring its long-term effective filtering performance.

[0008] As a further improvement to the above solution, the bottom end of the fixing block is fixedly connected to the top end of the drying cylinder, the left end of the servo motor is fixedly connected to the right end of the fixing block, and a transmission component is provided inside the fixing block.

[0009] The above technical solution provides a stable mounting base for the servo motor and support rod, ensuring that the servo motor will not shift due to its own vibration or external forces during operation, thus guaranteeing the stability of its output power. It also allows the support rod to firmly support the drive shaft and other related components.

[0010] As a further improvement to the above solution, the bottom end of the support rod is fixedly connected to the top end of the fixing block, the bottom end of the support rod is connected to the top end of the transmission assembly through the fixing block, and the inner wall of the rotating frame is connected to the inner wall of the support rod through the surface of the rotating shaft.

[0011] Through the above technical solution, the support rod provides support and guidance for the drive shaft. This ensures that the drive shaft maintains a stable axial position during rotation, reduces drive shaft wobble, and thus guarantees the accuracy and stability of power transmission, allowing the filter plate two to move up and down along a predetermined trajectory.

[0012] As a further improvement to the above solution, the bottom end of the transmission frame is fixedly connected to the top end of the second filter plate, the surface of the second filter plate is slidably connected to the inner wall of the drying cylinder, and the second filter plate is disposed inside the drying cylinder.

[0013] Through the above technical solution, the transmission frame converts the rotational motion of the transmission shaft into the vertical linear motion of the second filter plate. This motion conversion function enables the second filter plate to move up and down within the drying cylinder according to design requirements, achieving effective conversion between different motion modes. It is a key component for optimizing the filtration function of the second filter plate, ensuring the stability of its vertical movement during the conversion process. Through a reasonable structural design, the second filter plate will not tilt or wobble during its vertical movement, ensuring uniform filtration of the gas and improving filtration efficiency.

[0014] As a further improvement to the above solution, the bottom end of the arc-shaped block is fixedly connected to the top end of the drying cylinder, the right end of the rotating motor is fixedly connected to the left end of the arc-shaped block, a rotating assembly is provided inside the arc-shaped block, several rotating rods are provided, the left ends of several rotating rods are connected to the output end of the right end of the rotating motor through the rotating assembly inside the arc-shaped block, several connecting discs are provided, the left ends of several connecting discs are fixedly connected to the right ends of several rotating rods, and several cleaning brushes are provided, the left ends of several cleaning brushes are fixedly connected to the right ends of several connecting discs.

[0015] Through the above technical solution, filter plate two, as the second layer of filtration, can intercept smaller particulate impurities remaining after filtration by filter plate one. This further improves the purity of the gas, ensuring that the gas discharged from the dryer filter meets higher quality requirements. For example, in some industrial production or experimental environments with extremely high air quality requirements, the fine filtration function of filter plate two is crucial. The rotating rod transmits the power of the rotating motor to the connecting plate, ensuring that the power generated by the rotating motor can be stably transmitted to the connecting plate, thereby driving the cleaning brush to rotate. This is an important link in the cleaning power transmission chain.

[0016] As a further improvement to the above solution, the left end of the second filter plate is in contact with the right end of several cleaning brushes, and the ends of the two first filter plates that are close to each other are filled with desiccant.

[0017] Through the above technical solution, the cleaning brush directly cleans the surface of filter plate two. By rotating, it removes impurities from the surface of filter plate two, keeping the filter screen unobstructed and ensuring that the filtration performance of filter plate two does not decrease due to impurities clogging, thus extending the service life of filter plate two. The cleaning brush is an important component for maintaining the filtration effect of filter plate two. Regular cleaning of the brush ensures that filter plate two always maintains a good filtration state, thereby ensuring the filtration efficiency of the entire dryer filter. The desiccant absorbs moisture in the gas, reducing the humidity of the gas. When the gas passes between the two filter plates, the desiccant uses its own physical or chemical adsorption properties to adsorb the moisture in the gas on its surface or inside, making the gas discharged from the dryer filter drier, meeting the needs of some applications with requirements for gas dryness.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model employs a two-layer filtration structure—filter plate one and filter plate two—in a dryer filter. This multi-layer filtration more effectively intercepts impurities and improves filtration efficiency. For example, dust, particulate matter, and other impurities in the air first undergo preliminary filtration through filter plate one, where larger particles are intercepted. The gas then passes through filter plate two for further fine filtration, ensuring that the gas passing through the dryer filter is purer.

[0020] A handle is provided at the top of filter plate one, making it easy to pull out of the drying cylinder for cleaning or replacement. Although filter plate two is located inside the drying cylinder, it can be cleaned using a cleaning brush. A rotating motor drives a rotating rod, which in turn rotates the cleaning brush on the connecting plate, removing impurities from the surface of filter plate two. This design makes cleaning the filter plates more convenient, eliminating the need for complex disassembly and maintaining cleanliness, extending the service life of the filter plates, and thus ensuring the filtration effect of the dryer filter.

[0021] This invention involves filling one end of two filter plates close to each other with a desiccant. The desiccant effectively absorbs moisture in the gas, enabling the dry filter to not only filter impurities but also dry the gas. For example, in industrial production or equipment operating environments with strict humidity requirements, this drying function can prevent moisture from adversely affecting equipment or production processes, such as corrosion or interference with chemical reactions.

[0022] The servo motor and the rotary motor provide power for the movement of the filter plate and the rotation of the cleaning brush, respectively. This power distribution method can efficiently complete the up-and-down movement of the filter plate and the rotation of the cleaning brush, realizing the effective use of power and ensuring the normal operation of each function.

[0033] The drying cylinder 1 has an air vent 2 inside, and two filter plates 3 are provided. The surfaces of the two filter plates 3 are slidably connected to the inner wall of the drying cylinder 1. Two handles 4 are provided, and the bottom ends of the two handles 4 are fixedly connected to the top ends of the two filter plates 3.

[0034] The bottom end of the fixing block 5 is fixedly connected to the top end of the drying cylinder 1, the left end of the servo motor 6 is fixedly connected to the right end of the fixing block 5, and a transmission component is provided inside the fixing block 5.

[0035] The bottom end of the support rod 7 is fixedly connected to the top end of the fixing block 5. The bottom end of the support rod 7 is connected to the top end of the transmission assembly through the fixing block 5. The inner wall of the rotating frame is connected to the inner wall of the support rod 7 through the surface of the rotating shaft.

[0036] The bottom end of the transmission frame 9 is fixedly connected to the top end of the filter plate 10, the surface of the filter plate 10 is slidably connected to the inner wall of the drying cylinder 1, and the filter plate 10 is set inside the drying cylinder 1.

[0037] The bottom end of the arc-shaped block 11 is fixedly connected to the top end of the drying cylinder 1. The right end of the rotating motor 12 is fixedly connected to the left end of the arc-shaped block 11. A rotating component is provided inside the arc-shaped block 11. Several rotating rods 13 are provided. The left ends of the several rotating rods 13 are connected to the output end of the right end of the rotating motor 12 through the rotating component inside the arc-shaped block 11. Several connecting plates 14 are provided. The left ends of the several connecting plates 14 are fixedly connected to the right ends of the several rotating rods 13. Several cleaning brushes 15 are provided. The left ends of the several cleaning brushes 15 are fixedly connected to the right ends of the several connecting plates 14.

[0038] The left end of filter plate 2 10 contacts the right end of several cleaning brushes 15, and the ends of the two filter plates 1 3 that are close to each other are filled with desiccant 16.

[0039] The implementation principle of an easy-to-clean dryer filter in this embodiment is as follows: Gas enters the dryer filter from the air inlet 2 of the drying cylinder 1. The incoming gas first contacts filter plate 3. The filter structure of filter plate 3 can intercept larger particles of impurities. After preliminary filtration, the gas continues to flow into the drying cylinder 1 and then encounters filter plate 10. Filter plate 10 further filters out fine impurities in the gas, thereby achieving more thorough filtration. When the gas passes between the two filter plates 3, the desiccant 16 absorbs moisture from the gas. The desiccant 16 has a porous structure or chemical adsorption properties and can physically adsorb or chemically react with water molecules, thereby removing moisture from the gas and reducing the humidity of the gas passing through the dryer filter. When the servo motor 6 starts, it drives the transmission shaft 8 in the support rod 7 to rotate through the transmission component inside the fixed block 5. The rotation of the transmission shaft 8 causes the transmission frame 9 to move up and down. Since the bottom end of the transmission frame 9 is fixedly connected to the top end of the filter plate 10, the filter plate 10 also moves up and down. When the filter plate 10 needs to be cleaned, the rotating motor 12 starts. The output end of the rotating motor 12 drives the rotating rod 13 to rotate through the rotating component inside the arc block 11. The connecting plate 14 at the right end of the rotating rod 13 rotates accordingly. The cleaning brush 15 on the connecting plate 14 will brush the surface of the filter plate 10. Since the left end of the filter plate 10 is in contact with the right end of the cleaning brush 15, the cleaning brush 15 can effectively remove impurities from the surface of the filter plate 10.
