Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to an improved physical filtering device and a fish tank using the filtering device. Background Art

[0002] Automatic equipment in the field of physical filtration of fish tanks needs to solve the following four problems:

[0003] First, we need to solve the filtration problem: physical filtration media (cotton cores made of fiber, cotton, linen, sponge or mixed materials, quartz sand or other materials) can play a physical filtration role, intercepting the remaining bait, intercepting the impurities of fish tank feces, and playing a role in water purification;

[0004] The second is to solve the problem of automatic cleaning: automatic cleaning of physical filter media under the action of external forces;

[0005] The third is to solve the reset problem: the physical filter medium after automatic cleaning can be reset to the physical filter program position, and at the same time it can be switched to the cleaning state as needed in the filter position.

[0006] The Chinese invention patent application number 211910119207.3 describes an automatic fish tank purification device, in which the physical filtration structure has the following defects:

[0007] First, the design process of this kind of embedded physical filter cotton core is complicated and the cost is high;

[0008] Second, this kind of inlaid physical filter cotton core is driven by the locking ring plate and embedded in the groove on the top of the lock mother impeller for locking. The side outer wall of the lock mother impeller must have a certain thickness, which squeezes the space of the filter unit;

[0009] Third, the lower part of the filter element has poor water flow capacity and is difficult to clean;

[0010] The present invention is an improvement made on the basis of the above-mentioned technical problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] In some embodiments, the improved physical filtration device comprises:

[0044] Filter barrel 1;

[0045] A pulsator 9, wherein the pulsator 9 is located in the filter barrel 1 and is driven to rotate by a power source;

[0046] A filtering inclined plate 12, the filtering inclined plate 12 is circumferentially arranged on the periphery above the impeller 9 and fixed relative to the filtering barrel 1;

[0047] A supporting ring plate 14 for supporting the filter inclined plate 12, wherein a sealing space is formed between the inner wall of the supporting ring plate 14, the upper surface of the impeller 9 and the upper surface of the filter inclined plate 12;

[0048] The filter cotton core 4 is sealed in the sealing space under its own gravity, and is locked with the impeller 9 by a lock male 10 and a lock female 8, and can rotate together with the impeller 9.

[0049] Furthermore, the support ring plate 14 is provided with a clean water outlet communicated with the clean water tank 5 .

[0050] When the filter cotton core 4 and the impeller 9 are locked by the lock male 10 and the lock nut 8, the filter cotton core 4 is sealed in the sealing space, and an area not covered by the filter cotton core 4 remains on the filter inclined plate 12. The waste particles such as residual bait and feces in the raw water enter the sedimentation tank 6 after passing through the filter inclined plate 12, and the remaining raw water enters the clean water tank 5 after being filtered by the filter cotton core 4. The clean water in the clean water tank 5 enters the biochemical filter tank 20 for biochemical treatment and then returns to the fish tank.

[0051] The locking fit of the above-mentioned lock male 10 and lock nut 8 can also appear between the contact surface of the filter cotton core 4 and the support ring plate 14, that is, the support ring plate 14 in contact with the filter cotton core 4 is the lock nut 8, and the filter cotton core 4 is the lock male 10; and, in order to ensure the stability of the filter cotton core 4 in the sealing space, at least one group of the above-mentioned filter cotton core 4 and the impeller 9, and the filter cotton core 4 and the support ring plate 14 must form a locking fit, and from the perspective of the difficulty of processing and subsequent product maintenance, it is preferably that a locking fit of the lock male 10 and lock nut 8 is formed between the filter cotton core 4 and the impeller 9.

[0052] In addition, it should be noted that the structure of the impeller 9 and the rotation principle of the impeller 9 refer to the structure and rotation principle of the impeller 9 of the washing machine in the prior art. The only difference is that the middle part of the impeller 9 in this embodiment is provided with a lock male 10 / lock female 8 that cooperates with the filter cotton core 4 for sealing and locking.

[0053] In some embodiments, a deflection plate 13 is further provided in the filter barrel 1; the deflection plate 13 is located below the filter plate and is an annular plate with a slope, one side of which is fixedly connected to the inner wall of the filter barrel 1 and the other side of which is fixedly connected to the side wall of the support ring plate 14.

[0054] The filter plate is detachably connected to the support ring plate 14 ; preferably, the filter plate can be directly placed on the support ring plate 14 , so as to facilitate cleaning of the deflection plate 13 .

[0055] The outlet of the inclined plate 13 is connected to the sedimentation bin 6 , that is, the waste particles such as residual bait and feces pass through the filter plate and enter the sedimentation bin 6 along the inclined plate 13 .

[0056] In some embodiments, in order to provide a sealed environment for the power source, a base is set at the lower part of the filter barrel 1, and the base is mainly used to place the power source or the transmission mechanism of the power source, and at least the transmission mechanism of the power source is located in the base; the power source can be a motor 7; or human power, and the human power source is divided into human foot pedal or hand press.

[0057] Furthermore, the supporting ring plate 14 is disposed on the upper surface of the base.

[0058] In some embodiments, the positions of the lock male 10 and the lock nut 8 on the impeller 9 and the filter cotton core 4 can be interchanged; however, considering that the filter cotton core 4 needs to be replaced frequently and the processing cost of the lock nut 8 is higher than that of the lock male 10, preferably, the lock male 10 is arranged in the middle of the filter cotton core 4, and the lock nut 8 is arranged in the middle of the impeller 9;

[0059] The specific way of cooperation between the lock male 10 and the lock nut 8 is as follows: the outer edge of the lock nut 8 is provided with a trumpet-shaped guide bevel, and its internal groove cooperates with the columnar protrusion of the lock male 10. Preferably, the lock male 10 and the lock nut 8 are locked or separated along a V-shaped track 21. As shown in the figure, the V-shaped track 21 includes an upper entrance 211, a first guide bevel 212, a lower dead center 213, a second guide bevel 214 and a top dead center 215.

[0060] Now, taking "a lock nut 8 is arranged in the middle of the filter cotton core 4, and a lock male 10 is arranged in the middle of the impeller 9" as an example to illustrate the various matching processes of the lock male 10 and the lock nut 8, the locking and sealing process of the filter cotton core 4: the lock nut 8 in the middle of the filter cotton core 4 enters the first guide slope 212 along the upper inlet 211 of the head of the lock male 10 and then reaches the bottom dead point 213, so as to realize the sealing of the filter cotton core 4; the self-cleaning and separation process of the filter cotton core 4: the lock male 10 rotates forward (clockwise) with the impeller 9, and the lock nut 8 separates from the lock male along the first guide slope 212 10, that is, the filter cotton core 4 is separated from the impeller 9, and the filter cotton core 4 can be self-cleaned when the impeller 9 rotates left and right in the filter barrel 1 to create waves; the filter cotton core 4 locks the dehydration process: the lock nut 8 in the middle of the filter cotton core 4 enters the first guide slope 212 along the upper inlet 211 of the head of the lock male 10 and then reaches the bottom dead center 213, the lock male 10 rotates in the opposite direction (counterclockwise) with the impeller 9, the lock nut 8 enters the second guide slope 214 and then reaches the upper dead center 215, thereby, the filter cotton core 4 can be dehydrated and dried.

[0061] In some embodiments, the filter cotton core 4 includes a fiber filter layer 401 and a conical guide layer 402 which are arranged up and down and detachably connected. The fiber filter layer 401 is covered with a wool plate on the outside, and a plurality of filter holes are arranged on the wool plate. The conical guide layer 402 is provided with drainage holes communicating with the filter holes, and a counterweight block 403 is provided at the bottom thereof. The counterweight block 403 can be located inside or outside the conical guide layer 402; correspondingly, the sealing space is trumpet-shaped; the conical guide structure and the counterweight block 403 both contribute to the filter cotton core 4 entering the sealing space and realizing sealing in the sealing space.

[0062] The detachable connection between the fiber filter layer and the conical guide layer can be a common plug-in, clip-on connection, etc., so as to facilitate the replacement of the fiber filter layer.

[0063] In addition, a male lock 10 / a female lock 8 is provided at the lower part of the conical inclined guide layer 402 .

[0064] When the filter cotton core 4 is in the sealed state, raw water enters the fiber filter layer 401 through the filter holes for purification, and is discharged through the drainage holes and flows into the clean water tank 5 .

[0065] In some embodiments, in order to prevent the filter cotton core 4 from escaping from the filter barrel 1 during the self-cleaning process and to prevent water from splashing out, a detachable and / or foldable arc-shaped cover 19 relative to the filter barrel 1 may be provided at the upper inner portion of the filter barrel 1 .

[0066] In some embodiments, a sterilization lamp 23 is provided in the water purification tank 5, and a heating rod 22 is provided in the biochemical filtration tank 20. When the water temperature in the biochemical filtration tank 20 is lower than the set temperature, the heating rod 22 is turned on for heating; when the water temperature in the biochemical filtration tank 20 reaches the set temperature, the heating rod 22 stops heating.

[0067] The working principle of the improved physical filtration device in each mode in the above embodiment is as follows:

[0068] Under normal circumstances, when the drain valve 16 is opened, the liquid level in the filter barrel 1 drops, and the filter cotton core 4 drops along with the water level due to its own gravity. When the water level drops to a certain level, the lock male 10 in the middle of the filter cotton core 4 and the lock nut 8 in the middle of the impeller 9 contact and fit together (the lock nut 8 and the lock male 10 can be interchanged), thereby achieving the sealing of the filter cotton core 4 in the sealing space. At this time, the drain valve 16 is closed, and the filter barrel 1 is in a state of waiting for circulation filtration.

[0069] When the circulation mode of the filter cotton core 4 is started, the water pump 11 is in working state, the water inlet solenoid valve 3 is in open state, and the sealing cover on the top of the filter barrel 1 is closed relative to the sealing cover of the filter barrel. At this time, negative pressure is generated in the physical filter barrel 1, and the raw water carrying fish feces, residual bait and other impurities in the fish tank flows into the physical filter barrel 1 under the action of suction, and is sprayed on the barrel wall of the physical filter barrel 1 along a certain angle through the water distributor 2, so that the raw water generates centripetal force, which drives the raw water in the filter barrel 1 to rotate, and the raw water flows through the barrel wall through the filter plate, and the feces particles and feed residual bait in the fish tank fall to the inclination plate 13 due to gravity through the holes of the filter plate. The residual bait and feces flow into the sedimentation bin 6 along the inclined surface of the inclination plate 13 under the gravity of the water flow. The remaining raw water enters the clean water tank 5 after physical filtration through the filter cotton core 4. The check valve 18 in the clean water tank 5 opens under the action of the pressure difference, and flows into the biochemical filtration tank 20 for biochemical filtration. After the circulating water pump 11 works, it returns to the fish tank, realizing the large circulation flow of the fish tank water.

[0070] When the self-cleaning mode of the filter cotton core 4 is started, the water pump 11 stops working, and the check valve 18 of the clean water tank 5 is closed under the action of the pressure difference, cutting off the connection between the biochemical filter tank 20 and the clean water tank 5. The water inlet solenoid valve 3 continues to work and supply water after the flow design. When the liquid level in the physical filter barrel 1 reaches the designed position, the transmission mechanism of the motor 7 acts on the impeller 9, so that the impeller 9 can rotate left and right. The filter cotton core 4 located on the impeller 9 is separated from the impeller 9 along the V-shaped track 21 under the action of centrifugal force. With the rotation of the impeller 9, the water rotates with the water flow in the water body. Under the reaction force of the cover plate 19, the water flow falls into the filter barrel 1. The filter cotton core 4 is automatically cleaned under the action of centrifugal force and vortex, and then the sewage is discharged through the sewage valve 17 and the feces cleaning valve. After cleaning, the filter cotton core 4 descends under the action of gravity and enters the lower dead center 213 of the V-shaped track 21, and the sealing space is sealed at the same time.

[0071] When the filter cotton dehydration mode is started, the motor 7 makes the impeller 9 rotate unidirectionally, and the filter cotton core 4 located on the impeller 9 reaches the upper dead center 215 along the V-shaped track 21 under the action of centrifugal force, thereby locking the filter cotton core 4. The filter cotton core 4 is dehydrated and dried under the action of centrifugal force, so as to cooperate with more thorough cleaning. After the dehydration is completed, the filter cotton core 4 enters the waiting cycle filtration state.

[0072] The feces and bait residue self-cleaning mode is started, and the sewage valve 17 is opened. The feces and bait residue settled in the sedimentation bin 6 is discharged under the action of the pressure difference, and the sedimentation bin 6 is emptied, which greatly reduces the filtering pressure of the filter cotton core 4.

[0073] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
