[0002] At present, the common water treatment systems for exhibition fish tanks on the market adopt a hierarchical layout design, that is, the fish tanks are located in the exhibition area of the store, while the water treatment equipment (such as filter tanks, constant temperature machines, protein separators, circulation pumps, etc.) are centrally arranged in an independent machine room (such as the basement floor) below the store. Water flows back to the filter tank on the lower layer from the fish tank by gravity. After impurity filtration, protein separation, ultraviolet sterilization, etc. are carried out in the filter tank, the water is pumped back into the fish tank by a water pump to form a water circulation system. Some of the water treatment split systems for exhibition fish tanks distributed on the same floor adopt the method of no filtration unit in the return pipe for the return of the fish tank water. Some of the water treatment split systems for exhibition fish tanks distributed on the same floor adopt the method of baffle shelving to control the opening and closing of the display bin. Such water treatment split systems for exhibition fish tanks distributed on the same floor have some problems. For example, in the method of no filtration unit in the return pipe, some impurities may enter the inside of the return pipe, causing blockage of the return pipe and affecting the efficiency of the overall water circulation system.

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , this embodiment provides a technical solution: a split water treatment system for exhibition fish tanks distributed on the same floor, including a display bin 1, a quick-installation filtration mechanism 5 and a retractable shielding mechanism 6;

[0026] Display bin 1: A fish tank 2 is fixedly connected inside it. The display bin 1 is connected to the fish tank 2 through evenly distributed bolts. A filtration bin 3 is arranged at the rear of the display bin 1. The filtration bin 3 and the fish tank 2 are cooperatively installed. A controller 22 is arranged at the front end of the right surface of the filtration bin 3. The input end of the controller 22 is electrically connected to an external power supply;

[0027] Quick-installation filtration mechanism 5: It includes a thread groove 51, a thread barrel 52, a filtration bottom plate 53, a driving ring 54 and a filtration cover 55. The thread grooves 51 are evenly arranged at the bottom of the fish tank 2. Thread barrels 52 are threadedly connected inside the thread grooves 51. Filtration covers 55 are fixedly connected to the upper ends of the thread barrels 52. Filtration bottom plates 53 are fixedly connected to the lower ends of the thread barrels 52. Driving rings 54 are fixedly connected to the upper outer surfaces of the thread barrels 52. The thread barrels 52 are sequentially threaded into the corresponding thread grooves 51. During the operation of the split water treatment system for exhibition fish tanks, the water in the fish tank 2 enters the inside of the thread barrel 52 through the filtration cover 55, and then enters the connecting pipe after secondary filtration by the filtration bottom plate 53, and then enters the inside of the second horizontal pipe 10, and then enters the inside of the filtration bin 3 through the return pipe 11;

[0028] Retractable shielding mechanism 6: It is used for shielding the fish tank 2. The retractable shielding mechanism 6 includes a chute 61, a moving frame 62, a winding seat 63 and a shielding cloth 64. The chutes 61 are respectively arranged at the left and right ends of the display bin 1. A moving frame 62 is slidably connected between the two chutes 61. The front end of the upper surface of the display bin 1 is fixedly connected with a winding seat 63. A shielding cloth 64 is arranged inside the winding seat 63. The front end of the moving frame 62 is fixedly connected with the rear end of the shielding cloth 64.

The right end of the front rotating shaft 14 is fixedly connected with a driving handle. The upper ends of the transmission belts are all fixedly connected to the lower end of the moving frame 62. By rotating the front rotating shaft 14 through the driving handle, the front rotating shaft 14 drives the two driving wheels 15 to rotate. The driving wheels 15 drive the driven wheels 19 to rotate through the transmission belts. The rotation of the transmission belts causes the moving frame 62 to slide backward between the chutes 61. The moving frame 61 drives the shielding cloth 64 to move backward, so that the shielding cloth 64 closes the display bin 1;

[0029] Among them: Uniformly distributed water outlet pipes 7 are arranged inside the fish tank 1.

The horizontal pipe 2 10 is connected to the filtration chamber 3 through a return pipe 11. A refrigerator 4 is arranged at the rear side of the filtration chamber 3. A protein skimmer 18 is arranged at the upper end of the filtration chamber 3. The filtration chamber 3 is connected to the water inlet of the protein skimmer 18 through a connecting pipe 2. The water outlet of the protein skimmer 18 is connected to the inlet of the refrigerator 4 through a connecting pipe 3. The water outlet of the refrigerator 4 is connected to the longitudinal pipe through a water supply pipe 9. The input end of the refrigerator 4 is electrically connected to the output end of the controller 22. By means of the controller 22, the water pump 20 and the ultraviolet lamp 21 operate. The ultraviolet lamp 21 disinfects the filtered fish tank water with ultraviolet rays. The rear water pump 20 operates to pump the filtered fish tank water into the water inlet of the protein skimmer 18 through the connecting pipe 2. The protein skimmer 18 injects gas into the water to form bubbles. These bubbles will adsorb the particulate dirt and soluble organic matter in the water and float to the upper part of the separator to form a foam layer. Then, the foam adsorbed with dirt is collected and discharged, thereby purifying the water quality. Then, it enters the interior of the refrigerator 4 through the water outlet of the protein skimmer 18 and the connecting pipe 3. At the same time, the controller 22 makes the refrigerator 4 operate. The refrigerator 4 makes the filtered fish tank water reach the required water temperature. At the same time, the front water pump 20 operates to pump the water treated by the refrigerator 4 into the longitudinal pipe through the water supply pipe 9, and then sprays out through each water outlet pipe 7 to realize the circulation of the fish tank water;

[0030] Wherein: a bracket 16 is provided at the right end inside the filtration bin 3, evenly distributed filtration grooves 17 are inserted inside the bracket 16, baffles distributed in a staggered manner are fixedly connected to the left end of the filtration bin 3, symmetrically distributed ultraviolet lamps 21 are provided on the left inner wall of the filtration bin 3, and the input ends of the ultraviolet lamps 21 are electrically connected to the output end of the controller 22;

[0031] Wherein: water pumps 20 are provided on the bottom wall of the display bin 1 and the upper end of the filtration bin 3. The front water pump 20 is cooperatively installed with the front end of the water supply pipe 9, and the rear water pump 20 is cooperatively installed with the middle part of the second connecting pipe. Evenly distributed oxygen supply heads 12 are provided inside the fish tank 2, an oxygen increasing pump 13 is provided at the bottom of the display bin 1, the oxygen supply heads 12 are communicated with the oxygen outlet of the oxygen increasing pump 13 through air pipes, and the input ends of the oxygen increasing pump 13 and the water pumps 20 are electrically connected to the output end of the controller 22. The controller 22 enables the oxygen increasing pump 13 to operate, and the oxygen increasing pump 13 supplies oxygen to the oxygen supply heads 12 through the air pipes, thereby realizing the oxygen supply of the fish tank water.

[0032] The working principle of a split water treatment system for exhibition fish tanks distributed on the same floor provided by the present utility model is as follows: During operation, personnel first stably place the display bin 1, fish tank 2, and other mechanisms on a horizontal working area. After stable placement, personnel sequentially thread the threaded cylinder 52 into the corresponding threaded groove 51. During the operation of the split water treatment system for exhibition fish tanks, the water in the fish tank 2 enters the threaded cylinder 52 through the filter cover 55, and then enters the connecting pipe after secondary filtration by the filter bottom plate 53, and then enters the interior of the second horizontal pipe 10, and then enters the filter chamber 3 through the return pipe 11. The fish tank water passes through layers of filter grooves 17 and then enters the left end of the filter chamber 3. At the same time, personnel use the controller 22 to operate the water pump 20 and the ultraviolet lamp 21. The ultraviolet lamp 21 disinfects the filtered fish tank water with ultraviolet light. The water pump 20 at the rear operates to pump the filtered fish tank water into the water inlet of the protein skimmer 18 through the second connecting pipe. The protein skimmer 18 introduces gas into the water to form bubbles. These bubbles will adsorb particulate dirt and soluble organic matter in the water and float to the upper part of the separator to form a foam layer, and then collect and remove the foam adsorbed with dirt, thereby purifying the water quality. Then, it enters the interior of the chiller 4 through the water outlet of the protein skimmer 18 and the third connecting pipe. At the same time, the controller 22 operates the chiller 4. The chiller 4 makes the filtered fish tank water reach the required water temperature. At the same time, the water pump 20 at the front operates to pump the water processed by the chiller 4 into the vertical pipe through the water supply pipe 9, and then sprays out through each water outlet pipe 7 to realize the circulation of the fish tank water. When the store is closed, personnel rotate the front rotating shaft 14 through the driving handle. The rotation of the front rotating shaft 14 drives the two driving wheels 15 to rotate. The rotation of the driving wheels 15 both drives the driven wheels 19 to rotate through the transmission belt. The rotation of the transmission belt makes the moving frame 62 slide backward between the sliding grooves 61. The moving frame 61 drives the shielding cloth 64 to move backward, so that the shielding cloth 64 closes the display bin 1. At the same time, the controller 22 operates the oxygenation pump 13. The oxygenation pump 13 supplies oxygen to the oxygen supply head 12 through the air pipe, thereby realizing the oxygen supply of the fish tank water.

[0033] It should be noted that the controller 22 controls the operation of the oxygenation pump 13, water pump 20, and ultraviolet lamp 21 using common methods in the prior art in the above embodiments.

[0034] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
