Description

Technical Field

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

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

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

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

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

[0006] Fourth, we need to consider the problem of dehydration of the filter cotton core: the filter cotton core can be cleaned quickly with the help of dehydration.

[0007] The Chinese invention patent application number 211910119207.3 describes an automatic fish tank purification device, in which the structure of the physical filter part has the following defects:

[0008] First, the design process of this track-type physical filter cotton core is complicated and the processing cost is high;

[0009] Second, this track-type physical filter cotton core slides into the impeller and enters the track under the action of the bottom guide, which causes the flow area of ​​the filter cotton core to be very small, which is easier to be blocked and more likely to increase the frequency of washing, thereby increasing energy consumption;

[0010] Third, the filter cotton core is difficult to clean;

[0011] Fourthly, the filter cotton core slides down and is sealed by its own gravity, so the bottom of the filter barrel must be inclined to a certain extent. This takes up a lot of space for washing the filter cotton core and increases the height of the filter barrel to a certain extent, which puts higher requirements on the storage space of fish lovers.

[0012] The invention is an improvement based on the above technical problems. Summary of the invention

[0013] In response to the technical problems mentioned in the background technology, the technical solution of this invention provides a water quality filtering device and a fish tank using the water quality filtering device.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] In some embodiments, the water filtration device comprises:

[0046] Filter barrel 1;

[0047] The impeller 9 with filter holes is located in the filter barrel 1 and is driven to rotate by a power source;

[0048] The partition 12 is annularly arranged at the periphery of the impeller 9 and fixed relative to the filter barrel 1. The outer ring of the partition is integrally connected to the inclined groove 13, which is an annular groove with a slope, and the inclined groove is connected to the sedimentation bin 6;

[0049] A filter cotton plate 4, the filter cotton plate 4 with restoring force is located above the impeller 9, and is locked with the impeller 9 by a lock male 10 and a lock female 8, and can rotate with the impeller 9;

[0050] The filter barrel 1 is also provided with a sedimentation tank 6, a water purification tank 5 and a biochemical filtration tank 23;

[0051] When the filter cotton plate 4 and the impeller 9 are locked by the lock male 10 and the lock female 8, the middle part of the filter cotton plate 4 bulges upward, and its four sides are in contact with the upper surface of the partition 12, and there is a gap between the filter cotton plate 4 and the inner wall of the filter barrel 1, that is, there is an area at the edge of the partition that is not covered by the filter cotton plate, and the waste particles such as residual bait and feces enter the sedimentation bin 6 through the gap and the inclined groove 13 partition, and the raw water enters the clean water bin 5 after being filtered by the filter cotton plate 4, and the clean water in the clean water bin 5 enters the biochemical filter bin 23 for biochemical treatment and then returns to the fish tank;

[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 plate 4 for sealing and locking.

[0053] In some embodiments, a support ring plate 14 is further provided in the filter barrel 1. The support ring plate 14 is located on the base and is detachably connected or integrally connected to the base. The support ring plate can be directly used as a partition for the wall panels of the water purification tank 5, the sedimentation tank 6 and the biochemical filtration tank 23.

[0054] The partition plate 12 is detachably connected to the support ring plate 14 ; preferably, the partition plate 12 can be directly placed as a partition cover or embedded on the support ring plate 14 , so as to facilitate cleaning of the deflection groove 13 .

[0055] The support ring plate 14 is provided with a clean water outlet communicated with the clean water tank 5 .

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

[0058] The specific way of matching the lock male 10 and the lock nut 8 is as follows: the lock nut 8 has a trumpet-shaped guide bevel on its outer edge, and its internal groove matches the columnar protrusion of the lock male 10. Preferably, the lock male 10 and the lock nut 8 are locked or separated along the V-shaped track 21. Figure 4 As shown, the V-shaped track 21 includes an upper entrance 211 , a first guide slope 212 , a bottom dead center 213 , a second guide slope 214 and a top dead center 215 .

[0059] Now, taking "a lock nut 8 is arranged in the middle of the filter cotton plate 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 plate 4: the lock nut 8 in the middle of the filter cotton plate 4 enters the first guide bevel 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 plate 4; the self-cleaning and separation process of the filter cotton plate 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 bevel 212 10, that is, the filter cotton plate 4 is separated from the impeller 9, and the filter cotton plate 4 can be self-cleaned when the impeller 9 rotates left and right in the filter barrel 1 to create waves; the filter cotton plate 4 is locked in the dehydration process: the lock nut 8 in the middle of the filter cotton plate 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 plate 4 can be dehydrated and dried.

[0060] In addition, if the lock nut 8 is located in the middle of the filter cotton plate 4 , the lock nut 8 is a double-sided lock nut 8 to facilitate the double-sided installation of the filter cotton plate 4 relative to the impeller 9 .

[0061] In some embodiments, in order to achieve the sealing of the filter cotton plate 4 and the impeller 9, in addition to the cooperation of the lock male 10 and the lock female 8 at the center position, a metal part for magnetic adsorption is also provided at the edge of the filter cotton plate 4, thereby achieving close contact between the edge of the filter cotton plate 4 and the partition plate 12 in the area other than the inclined groove 13, thereby achieving further sealing of the filter cotton plate 4.

[0062] Specifically, the metal part is embedded in the inside of the edge of the filter cotton plate 4, or is covered on the outside of the edge of the filter cotton plate 4, and the metal part is a number of spaced-apart pieces, or is a continuous whole; preferably, the metal part is a metal sheet, and more preferably an iron sheet; correspondingly, an inner concave hole is provided on the outer bottom surface of the filter barrel 1 to hold a magnetic part that attracts the metal part, and the magnetic part corresponds to the upper and lower positions of the metal part. Preferably, the magnetic part is an electromagnet 22, and the electromagnet 22 is a number of spaced-apart pieces, or is a continuous whole.

[0063] Now, taking "a lock nut 8 is set in the middle of the filter cotton plate 4, and a lock pin 10 is set in the middle of the impeller 9" as an example, the sealing process of the filter cotton plate 4 under the attraction of the electromagnet 22 is explained: when the filter cotton plate 4 is in the filter barrel 1 as the water level drops, the lock nut 8 in the middle of the filter cotton plate 4 first enters the lower dead point along the first guide slope 212 of the lock pin 10 in the middle of the impeller 9, and as the water level further drops, the outer edge of the filter cotton plate 4 falls on the partition 12. At this time, the electromagnet 22 is turned on, and under the attraction of the electromagnet 22 and the iron sheet of the filter cotton plate 4, the filter cotton plate 4 is tightly attached to the impeller 9 and the partition 12 to achieve sealing.

[0064] In some embodiments, the filter cotton board 4 is composed of a multi-layer fiber cotton board 401; the multi-layer fiber cotton board 401 is provided with a central interlayer, which is made of an air cushion or other lightweight materials such as rubber, foam, etc., and an iron sheet may also be provided in the central interlayer; when the filter cotton board 4 is in the self-cleaning mode, the filter cotton board 4 can be bent and deformed arbitrarily, and after the cleaning stops, the filter cotton board 4 can be quickly stretched and float flat on the water surface. Considering the dehydration factor, the maximum design shape of the filter cotton board 4 is circular. Without considering the dehydration factor, the filter cotton board 4 can be set to any shape as long as it matches the shape of the filter barrel 1.

[0065] In some embodiments, in order to prevent the filter cotton plate from jumping out of the filter barrel during the self-cleaning process and to prevent water from splashing out, a cover plate 24 that is detachable and / or foldable relative to the filter barrel 1 can be provided at the upper part of the filter barrel.

[0066] In some embodiments, considering the height relationship between the fish tank, fish pond and filter barrel, a sealing cover 25 is preferably provided on the upper part of the filter barrel, so that the filter barrel is placed higher than the fish pond and fish tank and water can be sucked in, and there is no problem of affecting the raw water entering the filter barrel.

[0067] In some embodiments, a sterilization lamp 20 is provided in the water purification tank 5, and a heating rod 19 is provided in the biochemical filtration tank 23. When the water temperature in the biochemical filtration tank 23 is lower than the set temperature, the heating rod 19 is turned on for heating; when the water temperature in the biochemical filtration tank 23 reaches the set temperature, the heating rod 19 stops heating.

[0068] The working principle of the water quality filtration device in each mode in the above embodiment is as follows:

[0069] Under normal circumstances, the filter cotton plate 4 in the filter barrel 1 is attached to the water surface under the action of buoyancy because its own specific gravity is less than that of water. When the drain valve 16 is opened, the liquid level in the filter barrel 1 drops, and the filter cotton plate 4 drops along with the water level. When the water level drops to a certain level, the lock male 10 in the middle of the filter cotton plate 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) at the same time. At this time, the electromagnet 22 arranged on the outer side of the bottom of the filter barrel 1 is started, and the iron sheet carried on the filter cotton plate 4 is adsorbed by the electromagnet 22, and the filter cotton plate 4 as a whole is close to the impeller 9 and the partition 12 to achieve sealing. At this time, the drain valve 16 is closed, and the filter barrel 1 is in a state of waiting for circulation filtration.

[0070] When the circulating filtration mode is started, the water pump 11 enters the working state, the water inlet solenoid valve 3 is in the open state, and the sealing cover 25 is sealed relative to the filter barrel 1. At this time, the filter barrel 1 generates negative pressure, and the raw water carrying fish feces and other dirt in the fish tank flows into the filter barrel 1 under the action of suction, and is sprayed on the top of the filter cotton plate 4 along a certain angle through the water distributor 2, so that the raw water generates centrifugal force, which drives the raw water in the filter barrel 1 to rotate. The feces particles and feed residues in the fish tank are thrown to the filter barrel wall under the action of centrifugal force, and the feces particles and feed residues in the fish tank fall to the inclined groove 13 through the holes of the partition 12 due to gravity and flow into the sedimentation bin 6. After the remaining raw water is physically filtered through the filter cotton plate 4, it enters the space formed by the support ring plate through the filter holes of the impeller itself and the gap between the impeller and the support ring plate, and then enters the clean water tank 5 from the clean water outlet on the support ring plate. The single-flow valve 18 in the clean water tank 5 opens under the action of the pressure difference, and flows into the biochemical filtration tank 23 for biochemical filtration. After the circulating water pump 11 works, it returns to the fish tank through the outlet pipe 15, realizing the large circulation flow of the fish tank water.

[0071] When the self-cleaning mode of the filter cotton plate 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 23 and the clean water tank 5; the water inlet solenoid valve 3 continues to supply water after the flow design, and closes when the liquid level in the filter barrel 1 is at the designed position, and the water supply is stopped; the electromagnet 22 stops working, and acts on the impeller 9 through the transmission mechanism of the motor 7, so that the impeller 9 can rotate left and right, and the lock male 10 of the filter cotton plate 4 and the lock female 8 of the impeller 9 are separated. As the impeller 9 rotates to create flow, the filter cotton plate 4 rotates with the water flow in the water body, and is automatically cleaned under the action of centrifugal force and eddy current, and then the sewage is discharged through the drain valve 16 and the sewage valve 17. After cleaning, the filter cotton plate 4 floats on the water surface under the action of its own buoyancy. As the water level drops, the lock male 10 of the filter cotton plate 4 firstly enters the lock nut 8 along the trumpet-shaped lock nut 8 of the impeller 9. As the water level drops further, the filter cotton plate 4 falls on the impeller of the filter barrel 1. At this time, the electromagnet 22 is turned on, and the iron sheet of the filter cotton plate 4 and the electromagnet 22 attract each other, so that the filter cotton plate 4 is tightly attached to the impeller 9 and the partition 12, and the sealing is achieved.

[0072] When the filter cotton plate dehydration mode is started, the electromagnet 22 is powered off, and the power is transmitted to the impeller 9 through the motor 7, so that the impeller 9 rotates in one direction, and the locking male 10 of the filter cotton plate 4 and the locking female 8 of the impeller 9 are engaged. Under the action of centrifugal force, the filter cotton plate 4 reaches the upper dead center 215 along the V-shaped track 21, thereby locking the filter cotton plate 4. The filter cotton plate 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 plate 4 enters the waiting cycle filtration state.

[0073] 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 plate 4.

[0074] 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.
