Description

Technical Field

[0001] The present invention relates to the technical field of cleaning and filtering devices, and particularly to an ultrasonic-assisted cleaning and filtering device. Background Art

[0002] The surface water in Xinjiang has relatively high hardness and alkalinity. When filtering the irrigation surface water, in addition to the blockage by sediment particles, organic matters such as algae, during the water temperature change process and when the filter stops working, carbonates and sulfates in the water are likely to form deposits on the surface of the filter screen and solidify in the voids and on the surface of the filter screen, forming stubborn blockages. At the same time, impurities such as rust spots brought by pipeline water conveyance are also likely to block the filter screen and deposit and solidify to form stubborn blockages. The stubborn blockages also include chemical fertilizers crystallization, chemical deposits, rust spots, etc. generated by fertilization. Therefore, after the filter operates for a certain period of time, it cannot be cleaned back to the initial clean state by the normal cleaning device, and manual disassembly and cleaning are required, which is both labor-consuming and reduces the degree of automation.

[0003] In order to solve the above problems, the invention patent with the publication number of CN117504394A in the prior art discloses a hydroelectric hybrid-driven self-cleaning filter device and method, which includes a housing. The housing includes a filtering chamber and a sewage discharge chamber; a cleaning component is arranged in the filtering chamber, and one end of the cleaning component extends into the sewage discharge chamber and is connected to a hydraulic driving component and an electric driving component; the hydraulic driving component is located inside the sewage discharge chamber, and the hydraulic driving component and the electric driving component are used to drive the cleaning component in a hybrid manner. Although the internal part can be self-cleaned by the cleaning component in this invention, the cleaning effect is limited, and the stubborn blockages still cannot be cleaned off. Summary of the Invention

[0004] Aiming at the above problems in the prior art, the present invention provides an ultrasonic-assisted cleaning and filtering device, which solves the problem that stubborn stains such as chemical fertilizers crystallization, chemical deposits, rust spots, etc. generated by fertilization on the existing filter cannot be removed by the conventional cleaning component.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] Provided is an ultrasonic-assisted cleaning filter device, comprising a device body of a hydraulic-electric hybrid-driven self-cleaning filter device, the device body comprising a shell, the shell comprising a filter chamber and a sewage discharge chamber; a cleaning component is arranged in the filter chamber, one end of the cleaning component extends into the sewage discharge chamber and is connected with the hydraulic drive component and the electric drive component; the hydraulic drive component is located inside the sewage discharge chamber, the hydraulic drive component and the electric drive component are used to hybrid-drive the cleaning component, the filter chamber comprises a first filter chamber and a second filter chamber which are connected; the filter chamber and the sewage discharge chamber are connected through the cleaning component; the cleaning component comprises a hollow sewage discharge shaft located in a fine filter screen cylinder; a hollow flange is rotatably arranged between the first filter chamber and the second filter chamber, and a gear flange is rotatably arranged between the second filter chamber and the sewage discharge chamber; a coarse filter screen cylinder and a fine filter screen cylinder fixed on both sides of the hollow flange are respectively arranged in the first filter chamber and the second filter chamber, the other end of the fine filter screen cylinder is fixed on the gear flange, and the inner ring of the gear flange is connected to the hollow sewage discharge shaft through a planetary gear transmission; a plurality of ultrasonic transducers electrically connected to an ultrasonic generator are arranged on the shell.

[0007] In this solution, for flexible obstructions, the flexible obstructions on the fine filter mesh cylinder can be cleaned through the cleaning component; for stubborn blockages, since the fine filter mesh cylinder can be driven to rotate by the hollow sewage discharge shaft through the planetary gear during the filtration process, impurities such as carbonate, sulfate deposits and rust are not easy to deposit on the fine filter mesh cylinder during the filtration process, reducing the formation of stubborn blockages. When there are many stubborn blockages, the ultrasonic transducer can be used to send high-frequency pulses to clean the stubborn blockages, solving the problem that stubborn blockages are not only easy to form on the filter mesh of the existing filter but also cannot be removed.

[0008] Furthermore, the planetary gear includes a ring gear disposed on the inner ring wall of the gear flange, a transmission gear meshed with the ring gear, and a driving gear meshed with the transmission gear and disposed on the hollow sewage discharge shaft; wherein the hollow sewage discharge shaft drives the driving gear to rotate, the driving gear drives the ring gear to rotate through the transmission gear, and the ring gear drives the fine filter screen to rotate. The cooperation between the driving gear, the transmission gear and the ring gear ensures that the hollow sewage discharge shaft transmits power to the gear flange.

[0009] Furthermore, the diameter of the ring gear is larger than the diameter of the driving gear, and the diameter of the driving gear is larger than the diameter of the transmission gear. By setting the diameters of the driving gear, the transmission gear and the ring gear in this way, the fine filter cylinder is prevented from rotating too fast.

[0010] Furthermore, considering that the hollow sewage discharge shaft has two power sources, namely a hydraulic drive assembly and an electric drive assembly, when the hydraulic drive assembly drives the hollow sewage discharge shaft, the rotation speed of the hollow sewage discharge shaft is relatively slow. At this time, the driving gear needs to rotate at full speed. When both the hydraulic drive assembly and the electric drive assembly drive the hollow sewage discharge shaft, the rotation speed of the hollow sewage discharge shaft is relatively high. To avoid the fine filter screen cylinder rotating too fast and ensure the stability of the device, the rotation speed of the driving gear must be restricted at this time. Therefore, the driving gear is fixed to the hollow sewage discharge shaft through a speed-limiting clutch. The speed-limiting clutch can prevent the hollow sewage discharge shaft from rotating too fast and at the same time does not affect the transmission during the low-speed rotation of the hollow sewage discharge shaft.

[0011] Furthermore, the axis of the fine filter screen cylinder coincides with the axes of the hollow flange and the gear flange, and both the hollow flange and the gear flange are eccentrically arranged with respect to the hollow sewage discharge shaft. The eccentrically rotating fine filter screen cylinder will continuously change its contact position and angle with the sewage and the cleaning brush in the cleaning assembly during rotation, improving the cleaning strength of the cleaning brush. The eccentric movement can effectively prevent impurities such as carbonate, sulfate deposits, and rust spots from forming stubborn blockages on the fine filter screen. At the same time, the design of eccentric rotation makes the fine filter screen cylinder have a certain vibration during rotation, and this vibration can effectively shake off the blockages attached to the mesh holes, improving the self-cleaning ability. At the same time, the eccentric rotation movement mode enables the impurities to be more evenly distributed when passing through the fine filter screen cylinder, improving the cleaning uniformity.

[0012] Furthermore, a slide rail is arranged along the diameter direction passing through the center of the hollow sewage discharge shaft at one end of the fine filter screen cylinder close to the hollow flange. An eccentric block is slidably arranged on the slide rail, and the eccentric block is fixedly connected to the center of the hollow sewage discharge shaft on the slide rail through a spring. The setting of the eccentric block increases the eccentric force during the eccentric rotation of the fine filter screen cylinder, which is more conducive to preventing impurities such as carbonate, sulfate deposits, and rust spots from forming stubborn blockages on the fine filter screen. At the same time, the setting of the spring enables the eccentric block to adaptively change its position according to the rotation speed of the hollow sewage discharge shaft, thereby realizing the adaptive adjustment of the eccentric force with the change of the rotation speed. Specifically, when the hydraulic drive assembly drives the hollow sewage discharge shaft, the rotation speed of the hollow sewage discharge shaft is relatively slow. At this time, the eccentric block is close to the eccentric shaft of the fine filter screen cylinder. When both the hydraulic drive assembly and the electric drive assembly drive the hollow sewage discharge shaft, the rotation speed of the hollow sewage discharge shaft is relatively high. At this time, the eccentric block is far from the eccentric shaft of the fine filter screen cylinder.

[0013] Furthermore, considering that the eccentric block may hit the fine filter screen cylinder during the eccentric rotation of the fine filter screen cylinder, although the cleaning force is improved, to avoid damage to the fine filter screen cylinder and extend the service life of the fine filter screen cylinder, a buffer layer is arranged on the side of the eccentric block away from the spring.

[0014] Furthermore, the hollow sewage discharge shaft is a cylindrical structure with a hollow interior and closed ends. The hollow sewage discharge shaft is connected to a plurality of branch pipe groups evenly distributed along its axis. The plurality of ultrasonic transducers are in a one-to-one correspondence with the plurality of branch pipe groups, and each ultrasonic transducer is located on the outer ring of the corresponding branch pipe. The ultrasonic transducer is positioned in this way so that the ultrasonic transducer can better clean impurities on the fine filter cylinder at the suction nozzle and the cleaning brush located on the branch pipe group.

[0015] Furthermore, a plurality of grooves for fixing the ultrasonic transducer are provided on the outer wall of the housing, and the arrangement of the grooves reduces the distance between the ultrasonic transducer and the filter cylinder, thereby improving the cleaning effect of the ultrasonic transducer.

[0016] Furthermore, a plurality of grooves are arranged along a straight line, and each groove is located at a position on the outer wall of the housing at a minimum spacing between the filter screen cylinder and the inner wall of the housing during the eccentric rotation process. Such an arrangement enables the ultrasonic transducer in the groove to better remove the position of the fine filter screen cylinder where impurities are most likely to be deposited.

[0017] The invention discloses an ultrasonic-assisted cleaning filter device, which has the following beneficial effects:

[0018] 1. The present invention can remove flexible obstructions on the fine filter mesh cylinder through the cleaning component, and the fine filter mesh cylinder can be driven to rotate by the hollow sewage discharge shaft through the planetary gear during the filtration process, so that impurities such as carbonate, sulfate deposits and rust spots are not easily deposited on the fine filter mesh cylinder during the filtration process, reducing the formation of stubborn blockages. When there are many stubborn blockages, high-frequency pulses can be sent by ultrasonic transducers to clean the stubborn blockages.

[0019] 2. The present invention can effectively prevent carbonate, sulfate deposits, rust and other impurities from forming stubborn blockages on the fine filter by providing an eccentrically rotating fine filter cylinder. At the same time, the eccentric rotation design makes the fine filter cylinder vibrate to a certain extent during the rotation process. This vibration can effectively shake off the blockages attached to the mesh, thereby improving the self-cleaning ability. At the same time, the eccentric rotation movement mode enables impurities to be more evenly distributed when passing through the fine filter cylinder, thereby improving the cleaning uniformity.

However, it should be clear that the present invention is not limited to the scope of the specific implementation manners. For those of ordinary skill in the art of the present technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions created using the concept of the present invention are within the scope of protection

[0030] Embodiment 1

[0031] Refer to Figure 1 , and a ultrasonic-assisted cleaning and filtering device is provided. Based on the improvement of the hydraulic and electric hybrid drive self-cleaning filtering device, it includes the device body of the hydraulic and electric hybrid drive self-cleaning filtering device

[0032] The device body includes a housing 1, and the housing 1 includes a filtering chamber and a sewage discharge chamber; a cleaning assembly is arranged in the filtering chamber, and one end of the cleaning assembly extends into the sewage discharge chamber and is connected to a hydraulic drive assembly and an electric drive assembly. The hydraulic drive assembly is located inside the sewage discharge chamber, and the hydraulic drive assembly and the electric drive assembly are used to drive the cleaning assembly in combination. The filtering chamber includes a first filtering chamber and a second filtering chamber that are connected in communication; the filtering chamber and the sewage discharge chamber are connected through the cleaning assembly

[0033] The cleaning component includes a hollow sewage discharge shaft 3 located inside the fine filter screen cylinder 2. The hollow sewage discharge shaft 3 is a cylindrical structure with a hollow interior and closed ends. The hollow sewage discharge shaft 3 is connected to a plurality of branch pipe groups evenly distributed along its axis. Each branch pipe group includes at least two branch pipes arranged on the hollow sewage discharge shaft 3. A sewage suction nozzle for absorbing sewage and a cleaning brush for cleaning the fine filter screen cylinder 2 are respectively arranged on the two branch pipes.

[0034] Since the hydraulic and electric hybrid drive self-cleaning filtration device is a prior art, for details, refer to the invention patent with the publication number CN117504394A, and the specific working principle and connection relationship thereof will not be elaborated in this embodiment.

[0035] The improvement of this embodiment lies in that a hollow flange 21 is rotatably arranged between the first filter cavity and the second filter cavity, and a gear flange 22 is rotatably arranged between the second filter cavity and the sewage discharge cavity. A coarse filter screen cylinder and a fine filter screen cylinder 2 fixed on both sides of the hollow flange 21 are respectively arranged in the first filter cavity and the second filter cavity. The other end of the fine filter screen cylinder 2 is fixed on the gear flange 22. The inner ring of the gear flange 22 is in transmission connection with the hollow sewage discharge shaft 3 through a planetary gear 4. A plurality of ultrasonic transducers 5 electrically connected to an ultrasonic generator are arranged on or inside the housing 1.

[0036] Specifically, referring to Figure 2 , the planetary gear 4 includes an annular gear 43 arranged on the inner wall of the inner ring of the gear flange 22, a transmission gear 42 meshing with the annular gear 43, and a driving gear 41 meshing with the transmission gear 42 and arranged on the hollow sewage discharge shaft 3. The diameter of the annular gear 43 is larger than that of the driving gear 41, and the diameter of the driving gear 41 is larger than that of the transmission gear 42. By setting the diameters of the driving gear 41, the transmission gear 42 and the annular gear 43 in this way, the fine filter screen cylinder 2 is prevented from rotating too fast.

[0037] Among them, the hollow sewage discharge shaft 3 drives the driving gear 41 to rotate. The driving gear 41 drives the annular gear 43 to rotate through the transmission gear 42, and the annular gear 43 drives the fine filter screen cylinder 2 to rotate. The cooperation between the driving gear 41, the transmission gear 42 and the annular gear 43 ensures that the hollow sewage discharge shaft 3 transmits power to the gear flange 22. The transmission gear 42 and the driving gear 41 can be fixedly connected through a tie rod. The tie rod enables the transmission gear 42 to drive the annular gear 43 while rotating around the driving gear 41. The transmission gear 42 can also be directly fixed on the side wall of the second cavity through a transmission shaft.

[0038] In this embodiment, for stubborn blockages, since the fine filter mesh cylinder 2 can be driven to rotate by the hollow sewage discharge shaft 3 through the planetary gear 4 during the filtration process, impurities such as carbonate, sulfate deposits and rust spots are not easily deposited on the fine filter mesh cylinder 2 during the filtration process, thereby reducing the formation of stubborn blockages. When there are many stubborn blockages, the ultrasonic transducer 5 can be used to send high-frequency pulses to clean out the stubborn blockages, thereby solving the problem that the filter mesh of the existing filter is not only prone to stubborn blockages but also difficult to remove.

[0039] Preferably, reference Figure 2 and Figure 7 In this embodiment, the fine filter mesh cylinder 2 coincides with the center of the hollow sewage discharge shaft 3 , and a plurality of grooves 51 are provided on the outer wall of the shell 1 , and a plurality of ultrasonic transducers 5 are installed in the corresponding grooves 51 .

[0040] As a further solution of this embodiment, considering that the hollow sewage discharge shaft 3 has two power sources, namely, a hydraulic drive component and an electric drive component, when the hydraulic drive component drives the hollow sewage discharge shaft 3, the rotation speed of the hollow sewage discharge shaft 3 is relatively slow, and the driving gear 41 needs to rotate at full speed at this time. When the hydraulic drive component and the electric drive component drive the hollow sewage discharge shaft 3, the rotation speed of the hollow sewage discharge shaft 3 is relatively high. In order to prevent the fine filter cylinder 2 from rotating too fast and ensure the stability of the device, the rotation speed of the driving gear 41 must be limited at this time, so the driving gear 41 is fixed to the hollow sewage discharge shaft 3 through a speed limiting clutch. The speed limiting clutch can prevent the hollow sewage discharge shaft 3 from rotating too fast, and at the same time does not affect the transmission of the hollow sewage discharge shaft 3 during the low-speed rotation process.

[0041] Example 2

[0042] This embodiment is further limited on the basis of the embodiment 1, and the specific improvement lies in how to set the positions of multiple ultrasonic transducers 5 based on the ultrasonic-assisted cleaning filter device. For other parts not mentioned, refer to the embodiment 1 or the prior art.

[0043] In this embodiment, reference Figure 3 , multiple ultrasonic transducers 5 are respectively arranged at multiple suction nozzles on the hollow sewage discharge shaft 3. At this time, multiple ultrasonic transducers 5 are driven to rotate on the suction nozzles, and the planetary gear 4 is not needed to drive the fine filter screen cylinder 2 to rotate. At this time, the fine filter screen cylinder 2 is stationary. The ultrasonic transducers 5 are driven by the hollow sewage discharge shaft 3 to rotate the surface of the fine filter screen cylinder 2, which plays a cleaning role.

[0044] Example 3

[0045] This embodiment is further limited on the basis of Embodiment 1. The specific improvement lies in how to improve the self-cleaning effect of the filter device based on ultrasonic-assisted cleaning. For other parts not mentioned, refer to Embodiment 1 or the prior art.

[0046] Reference Figure 4 or Figure 5 In this embodiment, the axis of the fine filter cylinder 2 coincides with the axes of the hollow flange 21 and the gear flange 22, and both the hollow flange 21 and the gear flange 22 are eccentrically arranged with respect to the hollow sewage discharge shaft 3.

[0047] When the eccentrically rotating fine filter cylinder 2 rotates, it continuously changes its contact position and angle with the sewage and the cleaning brush in the cleaning assembly, improving the cleaning strength of the cleaning brush. The eccentric movement can effectively prevent impurities such as carbonate, sulfate deposits, and rust spots from forming stubborn blockages on the fine filter screen. At the same time, the design of the eccentric rotation makes the fine filter cylinder 2 have a certain vibration during the rotation process. This vibration can effectively shake off the blockages attached to the mesh holes, improving the self-cleaning ability. At the same time, the eccentric rotation movement mode enables the impurities to be more evenly distributed when passing through the fine filter cylinder 2, improving the cleaning uniformity.

[0048] As a further solution of this embodiment, referring to Figure 6 , a slide rail 6 is arranged along the diameter direction passing through the center of the hollow sewage discharge shaft 3 at one end of the fine filter cylinder 2 close to the hollow flange 21. An eccentric block 8 is slidably arranged on the slide rail 6, and the eccentric block 8 is fixedly connected to the center of the hollow sewage discharge shaft 3 on the slide rail 6 through a spring 7. The setting of the eccentric block 8 increases the eccentric force during the eccentric rotation of the fine filter cylinder 2, which is more conducive to preventing impurities such as carbonate, sulfate deposits, and rust spots from forming stubborn blockages on the fine filter screen. At the same time, the setting of the spring 7 enables the eccentric block 8 to adaptively change its position according to the rotation speed of the hollow sewage discharge shaft 3, thereby realizing the adaptive adjustment of the eccentric force with the change of the rotation speed. Specifically, when the hydraulic drive assembly drives the hollow sewage discharge shaft 3, the rotation speed of the hollow sewage discharge shaft 3 is slow, and at this time, the eccentric block 8 is close to the eccentric shaft of the fine filter cylinder 2. When the hydraulic drive assembly and the electric drive assembly drive the hollow sewage discharge shaft 3, the rotation speed of the hollow sewage discharge shaft 3 is high, and at this time, the eccentric block 8 is far from the eccentric shaft of the fine filter cylinder 2.

[0049] As a further solution of this embodiment, considering that the eccentric block 8 may hit the fine filter cylinder 2 during the eccentric rotation of the fine filter cylinder 2, although the cleaning force is improved, in order to avoid damage to the fine filter cylinder 2 and extend the service life of the fine filter cylinder 2, a buffer layer is provided on the side of the eccentric block 8 away from the spring 7.

[0050] Preferably, referring to Figure 4 or Figure 5, a plurality of ultrasonic transducers 5 of this embodiment are arranged on the outer wall or the inner wall of the housing 1. Specifically, the installation of the ultrasonic transducers 5 on the housing 1 is divided into internal fixed installation and external assembled installation. In the internal fixed installation, at this time, the ultrasonic transducers 5 and the fine filter screen cylinder 2 are transmitted through the water body. In the external assembled installation, after the ultrasonic transducers 5 pass through the housing 1, they are transmitted through the water body with the fine filter screen cylinder 2. The difference between these two situations is whether there is a housing isolation layer between the ultrasonic transducers 5 and the fine filter screen cylinder 2. And in order to enhance the cleaning efficiency in this embodiment, the number of ultrasonic transducers 5 placed on the housing 1 is twice the number of suction nozzles, that is, there is one-time repeated cleaning.

[0051] Embodiment 4

[0052] This embodiment makes further limitations on the basis of Embodiment 3. The specific improvement lies in how to set the positions of a plurality of ultrasonic transducers 5 based on the eccentrically rotating fine filter screen cylinder 2. For other parts not mentioned, refer to Embodiment 3 or the prior art.

[0053] In this embodiment, the hollow sewage discharge shaft 3 is a cylindrical structure with a hollow interior and closed ends. The hollow sewage discharge shaft 3 is communicated with a plurality of branch pipe groups uniformly distributed along its axis. A plurality of ultrasonic transducers 5 and a plurality of branch pipe groups are in one-to-one correspondence, and each ultrasonic transducer 5 is located on the outer ring of the corresponding branch pipe. By setting the positions of the ultrasonic transducers 5 in this way, the ultrasonic transducers 5 can better clean the impurities at the suction nozzles and cleaning brushes on the fine filter screen cylinder 2 located on the branch pipe groups.

[0054] Reference Figure 7 and Figure 8 , a plurality of grooves 51 for fixing the ultrasonic transducers 5 are opened on the outer wall of the housing 1. The setting of the grooves 51 reduces the distance between the ultrasonic transducers 5 and the filter screen cylinder, and improves the cleaning effect of the ultrasonic transducers 5.

[0055] A plurality of grooves 51 are arranged in a straight line, and each groove 51 is located at the position of the minimum distance between the outer wall of the housing 1 and the inner wall of the housing 1 during the eccentric rotation of the filter screen cylinder. By setting in this way, the ultrasonic transducers 5 in the grooves 51 can better remove the positions where impurities are most likely to deposit on the fine filter screen cylinder 2.

[0056] Although the specific implementation manners of the invention are described in detail in conjunction with the drawings, it should not be construed as a limitation on the protection scope of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative labor still fall within the protection scope of this patent.
