TECHNICAL FIELD

[0001] The present application relates to the field of water purification, and particularly relates to a ceramic membrane water purification equipment with a self-cleaning function. BACKGROUND

[0002] With the improvement of people's quality of life, whole-house water purification products are more and more popular among consumers. As a type of whole-house water purification products, ceramic membrane water purification equipment is mainly used for removing impurities such as dirt, rust and heavy metal ions in water. For the water purification equipment using ceramic membranes, after a certain period of use, the surface of the ceramic membrane will be covered with filtered impurities, resulting in a decrease in flux and filtration performance.

[0003] When judging whether to clean the ceramic membrane, the traditional water purification equipment mainly sets a cleaning period to remind regular cleaning of the ceramic membrane. This method cannot accurately determine whether the ceramic membrane is in a cleaning state. Meanwhile, the traditional equipment mainly uses disassembly of the ceramic membrane for cleaning. The above situations will greatly inconvenience the use experience.

[0004] In view of the above problems, the present application provides a ceramic membrane water purification equipment with a self-cleaning function to solve the above problems. SUMMARY

[0006] A water storage tank is provided with a plurality of supporting rods to bear the equipment;

[0007] A purification mechanism is fixed at one end of the top of the water storage tank and connected thereto; and

[0008] A water control mechanism is fixed at the other end of the purification mechanism.

[0009] Further, preferably, the purification mechanism comprises:

[0015] A ratchet wheel is fixed on the fixed rod, and a pair of cleaning brushes are fixed symmetrically on the ratchet wheel;

[0016] A plurality of multi-stage elastic telescopic rods are arranged, one end of each of which is fixed uniformly around the circumference of the turbofan shaft, and the other end of each of which is fixed on the ratchet wheel; and

[0017] A sewage valve is provided through the housing corresponding to one end of the cleaning brush, and the other end of the sewage valve is fixed on the support rod.

[0018] Further, preferably, the number of rotation circles of the cleaning brush driven by the turbofan during the rotation of the guide column from bottom to top is an integer, i.e., the cleaning brush can be restored to the initial position after rotation.

[0019] Further, preferably, the inner ring of the ratchet wheel is rotatably arranged on the fixed rod, and the inner ring is fixed with the multi-stage elastic telescopic rods; the outer ring of the ratchet wheel is rotatably arranged on the fixed rod, and the outer ring is symmetrically fixed with the cleaning brushes; the inner ring cannot drive the outer ring to rotate when the turbofan rotates counterclockwise, and the inner ring will drive the outer ring to rotate when the turbofan rotates clockwise, i.e., the cleaning brushes will remain stationary in the ceramic membrane filtration state, and the cleaning brushes will rotate in the ceramic membrane cleaning state.

[0020] Further, preferably, the sewage valve comprises:

[0021] An outer shell is fixed on the housing corresponding to the cleaning brush at one end, and is fixed on the support rod at the other end;

[0022] A fixed column is fixed around the circumference of the outer shell, and one end of a compression spring is fixed on the fixed column; and

[0026] Two water inlet pipes are arranged, one end of each of which is fixed symmetrically on a water source pipe, and the other end of each of which is fixed on the storage body;

[0027] A floating ball valve is fixed on the storage body, and a water inlet end of the floating ball valve is connected with the water inlet pipes, and a water outlet end of the floating ball valve is connected with the purification mechanism; and

[0028] A buoyancy plate is arranged in the housing, and is hingedly connected with the floating ball valve through a connecting rod.

[0029] Compared with the prior art, the ceramic membrane water purification equipment with self-cleaning function has the following beneficial effects:

[0030] In the present application, when the device is in the water purification state, the rotation of the vortex fan will generate a certain thrust on the water flow, causing the rotation and vortex of the water flow, which will make the water molecules more easily pass through the ceramic membrane, thereby increasing the filtering effect of the ceramic membrane on the water source.

[0031] When the device is in the self-cleaning state, the rotation of the vortex fan will generate a certain suction on the water flow, so that the impurities are detached from the surface of the ceramic membrane to a certain extent, further improving the cleaning strength of the cleaning brush on the ceramic membrane. At the same time, the rotation of the vortex fan will also make the water flow rotate, which will effectively improve the speed of the cleaned sewage passing through the sewage valve and improve the sewage discharge efficiency.

DETAILED DESCRIPTION

[0037] Reference Figs. 1-4 The present application provides a technical solution: a ceramic membrane water purification device with self-cleaning function, comprising:

[0038] The water storage tank 1 is provided with a plurality of support rods 2 to bear the device;

[0039] The purification mechanism 3 is fixed at one end of the top of the water storage tank 1 and connected thereto; and

[0040] The water control mechanism 5 is fixed at the other end of the purification mechanism 3.

[0041] As a preferred embodiment, the purification mechanism 3 comprises:

[0042] a housing 310 fixed on the water storage tank 1;

[0043] a crossbeam 31 fixed on the housing 310, and a fixing rod 32 fixed on the crossbeam 31;

[0044] a ceramic membrane 33 coaxially fixed on the housing 310 with the fixing rod 32;

[0045] a guide column 34 coaxially fixed on the fixing rod 32, and a guide ring fixed on the bottom of the guide column 34;

[0046] a vortex fan 35 coaxially rotatable arranged on the guide column 34, and a guide table arranged at the axis of the vortex fan 35, the guide table slidable in the slot of the guide column 34;

[0047] a ratchet wheel 36 fixed on the fixing rod 32, and a pair of cleaning brushes 38 fixed symmetrically on the ratchet wheel 36;

[0048] a plurality of multi-stage elastic telescopic rods 37, one end of which is fixed on the axis of the vortex fan 35, and the other end of which is fixed on the ratchet wheel 36; and

[0049] a sewage valve 39, one end of which penetrates the housing 310, and the other end of which is fixed on the support rod 2.

[0050] It is to be explained that when the water source flows into the housing 310 through the water control mechanism 5, the water source flows into the water storage tank 1 from top to bottom, and the water source drives the vortex fan 35 to rotate counterclockwise in the process of flowing. The vortex fan 35 gradually moves downward along the axis of the guide column 34 in the process of counterclockwise rotation due to the limiting effect of the axis guide table and the guide column 34. When the vortex fan 35 rotates to the lower end of the guide column 34, it falls into the guide ring at the bottom of the guide column 34, and the vortex fan 35 stops falling but keeps rotating counterclockwise under the action of water flow. At the same time, the multi-stage elastic telescopic rods 37 rotate synchronously and are compressed under the action of the vortex fan 35 rotating counterclockwise. The counterclockwise rotation of the vortex fan 35 cannot drive the cleaning brushes 38 to rotate under the action of the ratchet wheel 36, that is, the purification mechanism 3 is in the state of purifying and filtering the water source.

[0051] When the filtration efficiency of the ceramic membrane 33 on the water source gradually decreases, the water control mechanism 5 will passively adjust the water inflow rate of the water source according to its filtration efficiency to keep the water purification rate of the ceramic membrane 33 consistent with the water inflow rate, and the decrease in the water purification rate will cause the water flow rate to decrease, i.e. the rotation speed of the turbo fan 35 will decrease, which will effectively prevent the impurities settled on the surface of the ceramic membrane 33 from being lifted in large quantities, thereby hindering the cleaning effect of the cleaning brush 38 on the impurities on the ceramic membrane 33.

[0052] When the filtration efficiency of the ceramic membrane 33 on the water source cannot be kept consistent with the water inflow efficiency of the water control mechanism 5 (the surface of the ceramic membrane 33 is covered with impurities and cannot perform normal filtration work), the water control mechanism 5 will actively close the water inlet, at which time the water source in the shell 310 will not flow, i.e. the turbo fan 35 will stop counterclockwise rotation, and under the elasticity of the multi-stage elastic extension rod 37 and in cooperation with the guide column 34, the turbo fan 35 will rotate clockwise from bottom to top. Under the clockwise rotation of the turbo fan 35, the multi-stage elastic extension rod 37 will drive the ratchet wheel 36, so that the cleaning brush 38 automatically cleans the impurities on the ceramic membrane 33, and at the same time, during the cleaning process of the cleaning brush 38, the sewage valve 39 is opened, so that the sewage after cleaning is discharged in time to prevent the impurities from settling on the surface of the ceramic membrane 33 again, i.e. at this time, the purification mechanism 3 will be in a self-cleaning state.

[0053] It should be noted that when the device is in a water purification state, the rotation of the turbo fan 35 will generate a certain thrust on the water flow, causing the water flow to rotate and swirl, which will make the water molecules more easily pass through the ceramic membrane 33, thereby increasing the filtration effect of the ceramic membrane 33 on the water source; when the device is in a self-cleaning state, the rotation of the turbo fan 35 will generate a certain suction on the water flow, thereby causing the impurities to separate from the surface of the ceramic membrane 33 to some extent, further improving the cleaning strength of the cleaning brush 38 on the ceramic membrane 33, and at the same time, the rotation of the turbo fan 35 will also cause the water flow to rotate, which will effectively improve the speed at which the cleaned sewage can be discharged through the sewage valve 39, thereby improving the sewage discharge efficiency.

[0054] As a preferred embodiment, the turbo fan 35 can drive the cleaning brush 38 to rotate an integer number of turns during the rotation of the guide column 34 from bottom to top, i.e. the cleaning brush 38 can return to the initial position after rotating, so that the sewage valve 39 can be kept closed in the water purification state and opened in the cleaning state.

[0055] As a preferred embodiment, the inner ring of the ratchet 36 is rotatably arranged on the fixed rod 32, and the inner ring is fixed with the multi-stage elastic telescopic rod 37; the outer ring is rotatably arranged on the fixed rod 32, and symmetrically fixed with the cleaning brush 38; when the turbofan 35 rotates counterclockwise, the inner ring cannot drive the outer ring to rotate, and when the turbofan 35 rotates clockwise, the inner ring will drive the outer ring to rotate, that is, in the filtering state of the ceramic membrane 33, the cleaning brush 38 will remain stationary, and in the cleaning state of the ceramic membrane 33, the cleaning brush 38 will rotate.

[0056] As a preferred embodiment, the sewage valve 39 comprises:

[0057] The shell is fixed on the shell 310 at one end corresponding to the cleaning brush 38, and is fixed on the support rod 2 at the other end;

[0058] The fixed column 391 is fixed on the shell at a circumference, and one end of the compression spring 392 is fixed thereon; and

[0059] The convex valve plate 393 is slidably arranged in the shell, and the other end of the compression spring 392 is fixed thereon.

[0060] It should be noted that in the water purification state of the device, the convex valve plate 393 will be extruded into the shell under the action of the cleaning brush 38, so as to realize the closing of the sewage valve 39, and at the same time, the compression spring 392 will be compressed; when the device is in the self-cleaning state, the cleaning brush 38 will be extruded from the convex valve plate 393 in the rotating process, so that the convex valve plate 393 will be extruded out of the shell under the action of the compression spring 392, so as to open the sewage valve 39.

[0061] As a preferred embodiment, the water control mechanism 5 comprises:

[0062] The bin body 52 is fixed on the purification mechanism 3;

[0063] The water inlet pipeline 51 is arranged in two, one end of which is symmetrically fixed on the water source pipeline, and the other end is fixed on the bin body 52;

[0064] The float valve 53 is fixed on the bin body 52, and the water inlet end is connected with the water inlet pipeline 51, and the water outlet end is connected with the purification mechanism 3; and

[0065] The buoyancy plate 55 is arranged in the shell 310, and is hinged to the float valve 53 through the connecting rod 54.

[0066] It should be noted that the amount of water in the shell 310 can reflect the water purification efficiency of the ceramic membrane 33 when the device is in the water purification state, and the buoyancy plate 55 will adjust the opening degree of the float ball valve 53 according to the amount of water, so that the water inlet speed can match the water purification rate of the ceramic membrane 33, prevent the water from accumulating in the shell 310 when the water purification rate is reduced, and prevent the water pressure from being too large to reduce the water purification effect, and avoid the ceramic membrane 33 from bearing a large pressure to prolong its service life.

[0067] In specific implementation, the water source flows into the purification mechanism 3 through the water control mechanism 5, and flows from top to bottom in the normal water purification state to drive the rotation of the vortex fan 35, and the rotation of the vortex fan 35 will improve the water purification rate of the ceramic membrane 33; when the water source stops flowing in the purification mechanism 3, that is, the device is in the self-cleaning state, the vortex fan 35 will rotate clockwise to drive the rotation of the cleaning brush 38 to clean the impurities on the surface of the ceramic membrane 33.

[0068] The water source after water purification will flow to the water storage tank 1 for temporary storage.

[0069] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
