[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0054] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0055] First of all, it should be noted that the directions indicated by the six directional words "up", "down", "left", "right", "front" and "back" in this text are all attached with Figure 1 The currently indicated direction prevails.
[0056] The utility model embodiment discloses a breeding tank, as shown in the attached Figure 1 and 5 As shown, it includes a cylinder body 1, a bacteria culture box 2 and a filter 3. The cylinder body 1 is made of transparent materials such as glass or acrylic board. The bacteria culture box 2 and the filter 3 are both arranged in the cylinder body 1. A biochemical chamber is formed in the bacteria culture box 2. The biochemical chamber uses biochemical materials to perform biological filtration on the cylinder body 1. The filter 3 uses a filter core 33 to perform permeation filtration on the cylinder body 1. The two filtering methods ensure that the water quality of the cylinder body 1 is clean.
[0057] As attached Figures 9 to 12 As shown, the bottom end of the filter 3 is provided with a water inlet 31 and a water outlet 32, so that the filter 3 can achieve low water level water inlet and outlet, and can achieve low water level filtration. A filter cavity is formed in the center of the filter 3, and a filter core 33 is fixed in the filter cavity. The filter core 33 can be filter cotton, but is not limited thereto.
[0058] The filter element 33 divides the filter chamber into a sewage chamber 34 and a clean water chamber 35, which are distributed left and right. The sewage chamber 34 is connected to the cylinder body 1 through the water inlet 31, and the clean water chamber 35 is connected to the bacteria culture box 2 through the water outlet 32. During filtering, the sewage in the cylinder body 1 flows into the sewage chamber 34 from bottom to top through the water inlet 31, flows into the clean water chamber 35 from right to left after being filtered by the filter element 33, and the filtered clean water flows into the bacteria culture box 2 from top to bottom through the water outlet 32.
[0059] In summary, the utility model optimizes the filter 3 of the breeding tank, changing the original up and down filtering mode to the left and right filtering mode, eliminating the influence of gravity on the speed and pressure, and making the water outlet speed and water outlet pressure relatively stable, avoiding a large impact on the filter element 33, and the water flow in the filter 3 is more stable, and the filtering effect is better.
[0060] As attached Figures 14 to 16As shown, the bacteria culture box 2 in the utility model is a double-layer design, including an upper box body 21 and a lower box body 22 distributed up and down, so as to improve the space utilization rate of the bacteria culture box 2. The upper box body 21 and the lower box body 22 are stacked, and a limiting protrusion is protruding from the bottom end of the upper box body 21, and a limiting groove is correspondingly provided at the opening of the lower box body 22. The limiting protrusion and the limiting groove are concave-convexly engaged, so as to limit the staggered layers of the upper box body 21 and the lower box body 22, and realize a split design between the upper box body 21 and the lower box body 22, so as to facilitate disassembly and assembly during cleaning. Both the upper box body 21 and the lower box body 22 are box structures with one end closed and the other end open, and both are rectangular boxes, but are not limited thereto. The bacteria culture box 2 is placed at one end of the cylinder body 1, and the length of the bacteria culture box 2 is equal to the width of the cylinder body 1.
[0061] As attached Figures 17 to 19 As shown, the upper box body 21 is provided with an upper biochemical bin 211, and the lower box body 22 is provided with a lower biochemical bin 221. The upper biochemical bin 211 and the lower biochemical bin 221 are connected through a water delivery channel. The upper and lower distribution of the upper biochemical bin 211 and the lower biochemical bin 221 can extend the water flow path in the culture box 2 to a certain extent, and the purification is more complete and the filtering effect is better. A water pump 222 is fixed in the lower biochemical bin 221. The water pump 222 is used to send the water in the lower biochemical bin 221 from bottom to top along the water delivery channel into the upper biochemical bin 211, so as to provide power for the filtered clean water to flow in the culture box 2. In addition, as shown in the attached Fig.17 and 18 As shown, a plurality of reinforcing ribs 225 are fixedly disposed on the inner side wall of the lower box body 22 for supporting the upper box body 21 and improving the bearing capacity of the lower box body 22 .
[0062] The filter 3 in the utility model adopts an embedded setting, such as the attached Figures 6 to 8 As shown, a concave groove 23 is formed on the outer side of the culture box 2, and the filter 3 is embedded in the concave groove 23, so that the filter 3 and the culture box 2 are arranged in a compact manner, occupying less space in the cylinder body 1, providing sufficient space for aquatic organisms in the cylinder body 1; at the same time, the sanitary dead zone of the cylinder body 1 is reduced, and cleaning is more convenient. The front side of the filter 3 is flush with the front side of the concave groove 23.
[0063] As attached Fig.16 As shown, a diverter plate 231 is fixedly disposed at the bottom of the recessed groove 23. The diverter plate 231 is fixedly disposed parallel to the lower bottom plate 223 of the lower box body 22. There is a height difference between the diverter plate 231 and the lower bottom plate 223, so that a transition chamber 224 is formed between the diverter plate 231 and the lower bottom plate 223. Fig.18As shown, the transition chamber 224 is connected to the lower biochemical chamber 221; the diverter plate 231 is provided with a water inlet through hole 2311 and a water outlet through hole 2312, the water storage chamber 11 of the cylinder body 1 is connected to the water inlet 31 of the filter 3 through the water inlet through hole 2311, and the transition chamber 224 is connected to the water outlet 32 of the filter 3 through the water outlet through hole 2312. The diverter plate 231 is provided to divert the flow, connecting the upper biochemical chamber 211 and the filter 3.
[0064] As attached Fig.16 As shown, considering that the water outlet speed of the filter 3 is greater than the water inlet speed, the water inlet through hole 2311 is a rectangular hole penetrating along the thickness direction of the diverter plate 231, and the water outlet through hole 2312 is a long waist hole penetrating along the thickness direction of the diverter plate 231. The cross-sectional area of the water outlet through hole 2312 is greater than the cross-sectional area of the water inlet through hole 2311, which satisfies the water inlet and outlet speed difference of the filter 3. The hole edges of the water inlet through hole 2311 and the water outlet through hole 2312 are both surrounded by a plug sleeve 2313, which is plugged and matched with the water inlet 31 or the water outlet 32 of the filter 3, and the plug sleeve 2313 plays a guiding role. In addition, the water outlet through hole 2312 and the water pump 222 are respectively arranged at the two ends of the lower biochemical bin 221, which increases the water flow path of the lower biochemical bin 221, and the purification is more sufficient and the filtering effect is better.
[0065] As attached Fig.19 As shown, a guide plate 212 is vertically fixed in the upper biochemical warehouse 211, and the guide plate 212 extends along the length direction of the upper box body 21. The length of the guide plate 212 is less than the length of the upper box body 21, so that a connecting gap is formed between the guide plate 212 and the inner side wall of the upper box body 21. The guide plate 212 is vertically fixed on the upper bottom plate 215 of the upper box body 21, and divides the upper biochemical warehouse 211 into two, which are divided into a cold water chamber 2111 and a hot water chamber 2112. The cold water chamber 2111 and the hot water chamber 2112 are connected to each other through the connecting gap. A reinforcing rib is provided between the guide plate 212 and the upper bottom plate 215 to improve the mechanical strength of the guide plate 212. The setting of the guide plate 212 is used to guide the direction of the water flow in the upper biochemical warehouse 211, thereby extending the water flow path in the upper biochemical warehouse 211, and the purification effect is more sufficient and the filtering effect is better. A heater 213 is fixed in the hot water chamber 2112 to increase the water temperature of the hot water chamber 2112 and provide a suitable growth temperature for the aquatic organisms in the cylinder 1. The setting of the guide plate 212 can reduce the space of the hot water chamber 2112, so that the hot water chamber 2112 heats up faster, has higher heating efficiency, and is more energy-saving and environmentally friendly.
[0066] As attached Fig.19 As shown, the upper biochemical chamber 211 is provided with an upper water inlet 214 connected to the water supply channel. The upper water inlet 214 is arranged higher than the heater 213 to ensure that the heater 213 is always immersed in water to avoid the risk of dry burning.
[0067] As attached Fig.16As shown, the culture box 2 also includes an upper cover plate 24 covering the open portion of the upper box body 21, and an overflow port 25 is formed between the upper cover plate 24 and the upper box body 21. The two sides of the overflow port 25 are respectively connected to the water storage chamber 11 and the hot water chamber 2112 of the cylinder body 1, and the warm water in the hot water chamber 2112 flows into the water storage chamber 11 through the overflow port 25. The overflow port 25 is arranged at the top side edge of the upper box body 21, so that the overflow port 25 is higher than the heater 213, so as to prevent the heater 213 from being exposed outside the water, and further achieve anti-interference.
[0068] The sewage in the water storage chamber 11 of the cylinder body 1 flows into the water inlet 31 of the filter 3 along the water inlet through hole 2311, and flows into the sewage chamber 34 from the water inlet 31. The clean water filtered by the filter element 33 flows to the clean water chamber 35. The clean water then flows into the transition chamber 224 through the water outlet 32 and the water outlet through hole 2312 of the filter 3 in turn, and is merged into the lower biochemical chamber 221 from the transition chamber 224. The clean water is then pumped into the cold water chamber 2111 of the upper biochemical chamber 211 from bottom to top along the water delivery channel by the water pump 222, and is guided by the guide plate 212 to flow into the hot water chamber 2112, and is heated by the hot water chamber 2112. When the water level of the hot water chamber 2112 is higher than the overflow port 25, the warm water in the hot water chamber 2112 flows into the cylinder body 1 from the overflow port 25 to realize the purification cycle.
[0069] In addition, if attached Figures 1 to 5 As shown, a ladder 12 is also provided in the cylinder 1. The ladder 12 is arranged close to the outer wall of the culture box 2, so that aquatic organisms such as turtles can climb up the ladder 12 to the upper cover plate 24, providing aquatic organisms with both above-water and underwater breeding environments, which is beneficial to aquatic organism breeding and does not require a separate terrace, making the structure in the cylinder 1 more compact and the space utilization rate higher. A plurality of filter seats 13 are also laid at the bottom of the cylinder 1. In addition to providing support for the crawling of aquatic organisms, each filter seat 13 is also provided with a filter mesh, which filters the excrement and food residues of aquatic organisms in the cylinder 1 by sedimentation filtration, so that the impurities are settled at the bottom of the cylinder 1, and the purpose of purifying the cylinder 1 can also be achieved.
[0070] The aquaculture tank also includes a water temperature sensor for detecting the current water temperature of the upper biochemical warehouse 211, and the water temperature sensor and the heater 213 are both electrically connected to the controller. When the water temperature sensor detects that the current water temperature of the upper biochemical warehouse 211 is lower than the preset minimum water temperature, the water temperature sensor sends a signal to the controller, and the controller automatically starts the heater 213 to achieve automatic heating. When the water temperature sensor detects that the current water temperature of the upper biochemical warehouse 211 is higher than the preset maximum water temperature, the water temperature sensor sends a signal to the controller, and the controller automatically turns off the heater 213. The temperature control module formed by the water temperature sensor, the controller and the heater 213 can enable the heater 213 to start and stop automatically, ensure that the water temperature of the aquaculture tank is maintained within a constant range, provide an adaptive temperature for aquatic organisms, and do not require users to invest more energy in caring for aquatic organisms, and provide a better user experience.
[0071] It should be noted that the controller should include a signal receiving unit, a signal judging unit and a signal sending unit. The signal receiving unit is used to receive the electrical signal sent by the detection components such as the water temperature sensor. The signal judging unit and the signal receiving unit are electrically connected so that the signal judging unit is used to judge whether the signal received by the signal receiving unit is a trigger signal. The signal sending unit and the signal judging unit are electrically connected so that the signal sending unit sends the judgment signal generated by the signal judging unit to the execution components such as the heater 213. The specific setting methods of the signal receiving unit, the signal judging unit and the signal sending unit can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made to them. Obviously, the controller with this structure is widely used in existing automatic control equipment, such as MCU, DSP or single-chip microcomputer. The key point of the present utility model is that the controller is used to combine the water temperature sensor and the heater 213.
[0072] As attached Figures 10 to 12 As shown, the filter 3 includes a front shell 36 disposed away from the recessed groove 23. The front shell 36 is a transparent shell, so that the filter 3 adopts a visual design, which is convenient for the user to observe the clogging of the filter 3 in real time and remind the user to clean and replace the filter 3 in time. Fig.13 As shown, the filter 3 further includes a rear housing 37, and the front housing 36 and the rear housing 37 are buckled together to form a filter cavity. A plurality of support ribs 38 are fixedly provided on the side of the front housing 36 and the rear housing 37 facing the filter cavity, for supporting the filter element 33. The water inlet 31 of the filter 3 is provided at the bottom end of the front housing 36, and the water outlet 32 of the filter 3 is provided at the bottom end of the rear housing 37.
[0073] As attached Fig.13 As shown, the water inlet 31 is provided with a reverse osmosis valve 311, which is used to prevent the water in the filter 3 from reversely osmotic into the cylinder body 1 through the water inlet 31. The reverse osmosis valve 311 is a valve body that opens and closes by a rotating shaft. When the filter 3 is separated from the recessed groove 23 of the bacterial culture box 2, the reverse osmosis valve 311 is kept closed by the gravity exerted by the water body in the filter 3 to prevent leakage from the water inlet 31. When the filter 3 is installed in the recessed groove 23 of the bacterial culture box 2, the plug sleeve 2313 provided on the side edge of the water inlet through hole 2311 of the diverter plate 231 pushes open the reverse osmosis valve 311, the reverse osmosis valve 311 opens, the water inlet 31 is opened, and the filter 3 is connected to the cylinder body 1. The structure and working principle of the reverse osmosis valve 311 can refer to the prior art and will not be described in detail here.
[0074] As attached Figures 1 to 5 As shown, the breeding tank also includes a base 4 arranged at the bottom of the tank body 1 and a cover 5 arranged at the open end of the tank body 1, and the width of the cover 5 is smaller than the width of the tank body 1. Figures 20 to 23As shown, the cover body 5 is provided with a feeding hole 51, and the feeding hole 51 is provided with a pull-out plate 52. The pull-out plate 52 slides relative to the feeding hole 51 to adjust the size of the feeding hole 51. A landscape lamp 53 and a disinfection lamp 54 are also provided on the side of the cover plate facing the cylinder body 1. The landscape lamp 53 is a strip lamp, and the disinfection lamp 54 is composed of UVA, UVB and a full-spectrum white light lamp, which are used to disinfect and sterilize the cylinder body 1. The full English name of UVA in the text is Ultraviolet Radiation A, and the Chinese translation is Ultraviolet A band; the full English name of UVB in the text is Ultraviolet Radiation B, and the Chinese translation is Ultraviolet B band. In addition, the cover body 5 is also wrapped with an electronic control component, which is away from the cylinder body 1 to prevent the electronic control component from contacting water and improve safety.
