Description

Technical Field

[0001] The invention relates to the technical field of sewage purification equipment, and in particular to a filter membrane cleaning device. Background Art

[0002] Sewage purification plants are mainly used to purify domestic, chemical, agricultural and other types of sewage to obtain clean water, and then transport the clean water to thousands of households through pipe networks. In the process of sewage purification, a more common method is to use a filter membrane to physically filter the sewage, that is, to isolate the particles, bacteria, flocs, etc. in the sewage, so as to obtain clean water.

[0003] However, when the filter membrane is wet, some impurities tend to accumulate and adhere to the surface of the filter membrane, thereby blocking the filter holes, causing the filter membrane's filtration capacity to be greatly reduced or even losing its ability to purify sewage. To address this, the filter membrane needs to be cleaned and unblocked regularly, and the current conventional operation method is to manually scrub the surface of the filter membrane with a handheld cleaning brush or flush the surface of the filter membrane with a high-pressure water jet. These methods will cause the filter membrane to be subjected to direct physical impact, which can easily cause the filter membrane to tear and break, affecting its service life. Frequent replacement of the filter membrane will increase the cost of sewage purification. Summary of the invention

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1 As shown, a filter membrane 20 cleaning device according to an embodiment of the present application comprises: a biological filtration tank 10, a filter membrane 20, a vibration source mechanism 30 and a vibration transmission mechanism 40. The vibration source mechanism 30 is a power device that can generate and transmit vibration by itself, or does not generate vibration by itself, but can drive the vibration transmission mechanism 40 to generate vibration.

[0031] The filter membrane 20 is arranged in the biological filtration pool 10, and the filter membrane 20 separates the biological filtration pool 10 into a sewage chamber 11 and a clean water chamber 12; the vibration source mechanism 30 is arranged on the biological filtration pool 10; one end of the vibration transmission mechanism 40 is connected to the vibration source mechanism 30, and the other end of the vibration transmission mechanism 40 is connected to the filter membrane 20.

[0032] The implementation of the embodiment of the present invention will have the following beneficial effects: when the filter membrane 20 cleaning device of the above scheme is working, when the sewage flows into the clean water chamber 12 after passing through the sewage chamber 11 through the filter membrane 20, when the filter membrane 20 is blocked due to the accumulation of too many impurities, the vibration source mechanism 30 is started, and the vibration source mechanism 30 immediately generates high-frequency vibration, and the vibration can be transmitted to the vibration transmission mechanism 40, and the vibration transmission mechanism 40 can further transmit the vibration to the filter membrane 20, so that the filter membrane 20 generates high-frequency vibration, thereby destroying the static state of the impurities adhered to the surface of the filter membrane 20, so that the impurities are broken and separated from the filter membrane 20, and finally fall off from the surface of the filter membrane 20, thereby achieving the purpose of cleaning the filter membrane 20. Compared with the method of using direct physical impact force to remove impurities in the prior art, this scheme can avoid direct force on the filter membrane 20, so that the filter membrane 20 will not be torn and damaged, and the service life of the filter membrane 20 is guaranteed. At the same time, the replacement frequency of the filter membrane 20 can be reduced, and the cost of sewage purification treatment can be reduced.

[0033] In the above embodiment, specifically, the vibration source mechanism 30 is configured as a water jet mechanism, and the water jet mechanism is used to output a water jet to the vibration transmission mechanism 40 so that the vibration transmission mechanism 40 generates vibration and transmits the vibration to the filter membrane 20 .

[0034] Of course, in other embodiments, the vibration source mechanism 30 may also be a knocking mechanism, a blower mechanism, etc., which can be selected according to actual needs.

[0035] Please continue reading Figure 1 On the basis of the above embodiment, the water jet mechanism includes a mounting seat 31, a water pipe and a water spray head 32, the water pipe and the water spray head 32 are respectively installed on the mounting seat 31, and the water pipe is connected to the water spray head 32, and the water spray head 32 is arranged opposite to the vibration transmission mechanism 40.

[0036] Therefore, when working, the water pipe can deliver high-pressure water to the water spray head 32, and the water spray head 32 finally ejects the high-pressure water in the form of a water jet column onto the vibration transmission mechanism 40, driving the vibration transmission mechanism 40 to vibrate, and then synchronously driving the filter membrane 20 to vibrate, so that impurities adhered to the surface of the filter membrane 20 are vibrated and fall off, thereby achieving the effect of automatically cleaning the filter membrane 20.

[0037] In addition, based on any of the above embodiments, the water jet mechanism further includes a pressure regulating valve, which is arranged in the water pipe to adjust the water pressure of the water spray head 32. Alternatively, the water spray head 32 is arranged in a plurality, and at least two of the plurality of water spray heads 32 can simultaneously spray water to the vibration transmission mechanism 40. By such arrangement, according to the number and type of impurities adhering to the filter membrane 20, the purpose of adjusting the magnitude of the vibration force can be achieved by using the pressure regulating valve or selecting the number of water spray heads 32 working simultaneously, so that the water jet mechanism can work in an optimal working state while saving water resources and energy.

[0038] Please continue reading Figure 1 In some embodiments, the vibration transmission mechanism 40 includes a suspension rope 41, an impact-bearing plate 42 and a transmission joint 43. One end of the suspension rope 41 is arranged on the side wall of the biological filtration tank 10, and the other end of the suspension rope 41 is connected to the impact-bearing plate 42. The impact-bearing plate 42 is connected to the filter membrane 20 through the transmission joint 43.

[0039] The impact bearing plate 42 can be connected and fixed to the biological filtration tank 10 through the suspension rope 41, and this connection structure will not affect the impact bearing plate 42 receiving and transmitting vibration to the filter membrane 20. The impact bearing plate 42 is a component that directly bears the water jet. When the water jet hits the impact bearing plate 42, vibration will be generated. Preferably, the water jet uses an intermittent spraying method to spray the impact bearing plate 42 to ensure that the impact vibration plate vibrates more obviously and expands the vibration amplitude, so that impurities are more easily removed from the surface of the filter membrane 20.

[0040] In some other embodiments, the impact bearing plate 42 is provided with a plurality of water holes, and the plurality of water holes are arranged in a regular or irregular interval structure. The provision of the water holes helps to adjust the impact force on the impact bearing plate 42, and prevents the impact vibration plate from shaking significantly due to excessive impact force, thereby generating a pulling force on the filter membrane 20, and causing the filter membrane 20 to tear and be damaged.

[0041] Specifically, the water holes can be any of round holes, strip holes, etc. The arrangement structure of the plurality of water holes is not specifically limited here, for example, a regular (such as array) structure or an irregular structure arrangement can be adopted.

[0042] Please continue reading Figure 1 In addition, in some other embodiments, the transmission joint 43 includes a first joint arm 431 and a second joint arm 432, one of which is provided with a rotating seat, and the other of which is provided with a rotating body, which is rotatably connected to the rotating seat. Therefore, the first joint arm 431 can rotate relative to the second joint arm 432, so as to adapt to the amplitude of the vibration force, so that the vibration can be better transmitted to the filter membrane 20, avoiding deformation or even breakage due to rigid connection.

[0043] Preferably, the rotating body is set as a spherical body, the rotating seat is concavely formed with a spherical groove, and the spherical body can be universally rotatably inserted into the spherical groove. Since the water jet may be shot at the impact bearing plate 42 from different directions, the impact bearing plate 42 will also generate vibrations with different amplitudes in different directions. After such a setting, the transmission joint 43 can adapt to the transmission of vibration forces in different directions to the filter membrane 20, thereby improving the applicability of the transmission joint 43.

[0044] Furthermore, the filter membrane 20 cleaning device further comprises a spray assembly 50, which is arranged at the top of the biological filtration pool 10 and above the filter membrane 20, and comprises a bracket 51 and a spray pipe 52, wherein the spray pipe 52 is arranged on the bracket 51, and the bottom of the spray pipe 52 is provided with a plurality of spray holes facing the filter membrane 20 and arranged side by side at intervals. Therefore, by spraying water to the filter membrane 20, the water flows downward along the surface of the filter membrane 20, which helps to clean the impurities separated from the surface of the filter membrane 20, thereby improving the cleaning effect of the filter membrane 20.

[0045] Preferably, a water column with a certain pressure is sprayed out from the spray hole, which can have the effect of impacting impurities, thereby better allowing the impurities to fall off the surface of the filter membrane 20 and be carried away by the water flow.

[0046] Please continue reading Figure 1 On the basis of the above embodiment, the filter membrane 20 cleaning device further includes a first positioning component 60 and a second positioning component 70, both of which are arranged on the side wall of the biological filtration tank 10, and the first positioning component 60 is connected to one side of the filter membrane 20, and the second positioning component 70 is connected to the other opposite side of the filter membrane 20. The first positioning component 60 and the second positioning component 70 are used to support and stabilize the filter membrane 20, ensure the stability of the position and structure of the filter membrane 20, and prevent the filter membrane 20 from shaking due to excessive vibration. Specifically, the first positioning component 60 and the second positioning component 70 are composed of a positioning ring and a positioning rope.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
