Description

Technical Field

[0001] This utility model belongs to the field of agricultural water-saving irrigation technology, and in particular relates to a self-rotating submersible filter. Background Technology

[0002] The area under water-saving irrigation has been steadily increasing year by year, while the effective utilization coefficient of irrigation water has been continuously improving.

[0003] Currently, the most common filters used in micro-irrigation include sand filters, disc filters, hydrocyclones, and mesh filters. Their overall operation and performance differ, resulting in varying filtration effectiveness. However, the most significant problem is that the filter screens are particularly prone to clogging during use, affecting the reliability of the equipment. Furthermore, cleaning the filter screens after a period of use is very inconvenient, often requiring manual cleaning.

[0004] Therefore, how to solve the above problems has become a key research topic in the existing technology field. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a self-rotating submersible filter, which solves the above problems.

[0006] To achieve the above objectives, this utility model discloses a self-rotating submersible filter, comprising:

[0007] The support frame has floats on both sides and a roller in the middle; wherein the roller is rotatably connected to the support frame.

[0008] The roller includes a front sealing plate, a perforated screen, a rear sealing plate, and a water outlet assembly. One end of the perforated screen is connected to the front sealing plate, and the other end is connected to the rear sealing plate. The water inlet of the water outlet assembly is located inside the roller, and the roller and the water outlet assembly are rotatably in contact.

[0009] A self-rotating device is disposed inside the water outlet assembly and connected to the drum. When water is discharged from the water outlet assembly, the water entering the water outlet assembly drives the self-rotating device to rotate, thereby driving the drum to rotate around the support.

[0010] Compared with existing technologies, this application has the following advantages: the drum floats on the water surface under the action of the float; because the water inlet of the water outlet component is located inside the perforated screen, the water drawn by the water outlet component is all filtered water through the perforated screen, ensuring water quality; the water outlet component continuously receives water under the action of an external pumping device, and the water entering the water outlet component pushes the rotating device to rotate, which in turn drives the perforated screen to rotate. The rotation of the perforated screen not only continuously changes the water inlet position, but also automatically cleans away the debris clogging the perforated screen, ensuring that the perforated screen can continuously receive water and maintain its filtration effect. In summary, the filter designed in this application does not require an external power source; it can automatically clean the perforated screen through the self-rotation caused by water flow, avoiding screen clogging and reducing labor costs.

[0011] Furthermore, the self-rotating device includes an impeller and a shaft, with the impeller mounted on the shaft.

[0012] Furthermore, the rotating shaft is connected to the front sealing plate via a bushing. The two ends of the rotating shaft are respectively mounted on the bracket and the water outlet assembly via support bearings and bearing seats. When the water outlet assembly discharges water, the impeller drives the rotating shaft to rotate under the action of the water flow, thereby driving the front sealing plate to rotate, thus realizing the rotation of the perforated screen.

[0013] Furthermore, the water outlet assembly includes a water outlet pipe, with the inlet end of the water outlet pipe disposed inside the drum and the outlet end of the water outlet pipe disposed outside the drum and connected to an external pumping device; wherein, the end of the inlet end of the water outlet pipe does not contact the front sealing plate, and the rear sealing plate abuts against the water outlet pipe through a support roller, so that when the drum rotates, the rear sealing plate rotates around the water outlet pipe.

[0014] Furthermore, the end of the water inlet of the water outlet pipe is connected to the rotating shaft via a bearing seat and a bearing, and the water outlet of the water outlet pipe is mounted on the bracket.

[0015] Furthermore, the water outlet pipe is provided with multiple water inlets at its inlet end.

[0016] Furthermore, there are two water inlets, which are located at the end of the water inlet of the water outlet pipe.

[0017] Furthermore, it also includes a cleaning assembly for rinsing the perforated mesh.

[0018] Furthermore, the cleaning assembly includes an internal cleaning assembly and an external cleaning assembly for cleaning the inside and outside of the mesh.

[0019] Furthermore, the pontoon is a foam tube. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-3 As shown, this utility model discloses a self-rotating submersible filter, comprising:

[0029] The support frame 1 has floats 2 on both sides and a roller 3 in the middle. The floats 2 can be foam tubes. The design of the floats 2 allows the roller 3 to float on the water surface, preventing the equipment from sinking into the water and making it inconvenient to move. The roller 3 is rotatably connected to the support frame 1, so as to ensure that the roller 3 can rotate relative to the support frame 1 under the action of external force.

[0030] The roller 3 includes a front sealing plate 31, a perforated screen 32, a rear sealing plate 33, and a water outlet assembly. One end of the perforated screen 32 is connected to the front sealing plate 31, and the other end is connected to the rear sealing plate 33. The water inlet end 4 of the water outlet assembly is located inside the roller 3, and the roller 3 and the water outlet assembly can rotate and abut against each other. The front sealing plate 31 and the rear sealing plate 33 are connected to the perforated screen 32 by bolts and fasteners, which facilitates disassembly later.

[0031] The self-rotating device is installed inside the water outlet assembly and is connected to the drum 3. When water is discharged from the water outlet assembly, the water entering the water outlet assembly drives the self-rotating device to rotate, and then the self-rotating device drives the drum 3 to rotate around the support 1.

[0032] Compared with the prior art, this application has the following advantages: the roller 3 floats on the water surface under the action of the float 2; because the water inlet 4 of the water outlet component is set inside the perforated screen 32, the water drawn by the water outlet component is all water filtered by the perforated screen 32, thus ensuring water quality; the water outlet component starts to continuously receive water under the action of the external water pumping device, and the water entering the water outlet component pushes the self-rotating device to rotate, which in turn drives the perforated screen 32 to rotate. The rotation of the perforated screen 32 not only realizes the continuous change of the water inlet position, but also automatically cleans away the debris clogging the perforated screen 32, thus ensuring that the perforated screen 32 can continuously receive water and maintain the filtration effect of the perforated screen 32. In summary, the filter designed in this application does not require an external power source, and can automatically clean the perforated screen through the self-rotation under the action of water flow, avoiding screen clogging and reducing labor costs.

[0033] Following the above embodiments, more specifically, as Figure 4 As shown, the self-rotating device includes an impeller 7 and a rotating shaft 8, with the impeller 7 mounted on the rotating shaft 8. The rotating shaft 8 is connected to the front sealing plate 31 via a bushing. Both ends of the rotating shaft 8 are mounted on the bracket 1 and the water outlet assembly via support bearings 9 and bearing seats, respectively. When water is discharged from the water outlet assembly, the impeller 7 drives the rotating shaft 8 to rotate under the action of the water flow. This, in turn, causes the rotating shaft 8 to rotate the front sealing plate 31, thereby rotating the perforated screen 32. Ultimately, this continuously changes the water inlet position of the perforated screen 32, reducing the probability of clogging and improving water inlet efficiency.

[0034] Following the above embodiment, more specifically, the water outlet assembly includes a water outlet pipe 5, with the inlet end of the water outlet pipe 5 located inside the drum 3 and the outlet end of the water outlet pipe 5 located outside the drum 3 and connected to an external pumping device; wherein, the end of the inlet end of the water outlet pipe 5 does not contact the front sealing plate 31, and the rear sealing plate 33 abuts against the water outlet pipe 5 through a support roller, so that when the drum rotates, the rear sealing plate 33 rotates around the water outlet pipe 5. The pumping device can be a water pump, which is connected to the outlet end 6 of the outlet pipe 5 via a water pipe. When the pump is started, water will continuously enter the perforated screen 32 from outside the screen and then into the outlet pipe 5. Since the impeller 7 is located inside the outlet pipe 5, the water entering the outlet pipe 5 will drive the impeller 7 to rotate, which will further drive the shaft to rotate. The shaft will then drive the front sealing plate 31 to rotate, and the front sealing plate 31 will drive the perforated screen 32 and the rear sealing plate 33 to rotate. Thus, the rear sealing plate 33 will rotate around the outlet pipe 5 through the support roller. In this way, when the drum 3 rotates, the stationary outlet pipe 5 will not obstruct the rotation of the drum 3.

[0035] Following the above embodiment, a more preferable embodiment is that the end of the water inlet of the water outlet pipe 5 is connected to the rotating shaft 8 via a bearing seat and a bearing, and the water outlet of the water outlet pipe 5 is mounted on the bracket 1. However, if the water outlet pipe 5 is mounted on the bracket 1 at only one point, it will cause instability in the installation of the water outlet pipe 5. Therefore, in this application, one end of the water outlet pipe 5 is mounted on the bracket 1, and the other end is connected to the rotating shaft 8 via a bearing seat and a bearing. In this way, the rotating shaft 8 not only provides a second support point for the water outlet pipe 5, greatly improving the installation stability of the water outlet pipe 5, but also ensures that the water outlet pipe 5 does not affect the rotation of the rotating shaft 8.

[0036] Following the above embodiment, more specifically, the water inlet end of the water outlet pipe 5 is provided with multiple water inlets to ensure that water entering the drum 3 continuously flows into the water outlet pipe 5 through the water inlets. Preferably, there are two water inlets, which are located at the end of the water inlet end of the water outlet pipe 5. This way, water can only enter the water outlet pipe 5 through the end of the water outlet pipe 5, which can increase the water flow speed in the water outlet pipe 5, thereby increasing the impact force on the impeller 7, and thus making the rotating shaft 8 rotate faster, enabling the perforated screen 32 to rotate faster and reducing the probability of the perforated screen 32 becoming clogged.

[0037] Following the above embodiment, a more preferable method is to further include a cleaning assembly for rinsing the perforated mesh 32, with the cleaning assembly connected to an external rinsing water source. The cleaning assembly includes an internal cleaning assembly 10 and an external cleaning assembly 11 for cleaning the inside and outside of the perforated mesh 32. When the roller 3 rotates for a certain period, certain impurities will adhere to the surface of the stainless steel perforated mesh 32, affecting water filtration. The internal cleaning assembly 10 and the external cleaning assembly 11 can be activated to clean the perforated mesh 32, thoroughly resolving the problem of mesh blockage. It should be noted that during the cleaning process, the cleaning assembly also applies an impact force to the perforated mesh 32, thereby driving the perforated mesh 32 to rotate.

[0038] It should be noted that because the perforated screen 32 rotates continuously when the water pump is working, the internal cleaning component 10 and the external cleaning component 11 do not need to be moved to thoroughly clean the perforated screen 32.

[0039] In summary, the roller 3 used in this application does not require external power to drive it and can rotate by water flow, preventing the perforated screen 32 from clogging. Moreover, the designed cleaning components can thoroughly clean the perforated screen 32, further solving the problem of clogging and ensuring the normal operation of the entire equipment.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
