Description

Technical Field

[0001] This utility model relates to the technical field of bullfrog farming, and in particular to a bullfrog farming recirculating water device. Background Technology

[0002] Bullfrogs are amphibious and prefer places like rivers, ponds, riverside grass, or swamps. Therefore, when raising them, it is best to artificially construct shady caves and dense grass, and use silt to simulate a terrestrial environment to meet the bullfrogs' habitat requirements. In addition, bullfrogs are animals that require high water cleanliness, so it is necessary to use a water recycling system to circulate and treat the water.

[0003] Currently, in most commercially available circulating water systems, impurities gradually accumulate in the filter tank during basic water filtration. If not cleaned promptly, this not only reduces filtration efficiency but can also breed bacteria, negatively impacting the bullfrogs' health. Therefore, staff need to frequently clean the filter tank and screens. This significantly increases the workload for workers and can also lead to secondary water pollution due to untimely or incomplete cleaning, thus affecting the bullfrog farming environment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a bullfrog breeding recirculating water device. Through the design of the filtration mechanism, the water discharged from the breeding pond can be subjected to double filtration treatment. During the filtration process, impurities on the filter screen are scraped off and discharged into the slag collection box through the slag outlet.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a bullfrog breeding recirculating water device, comprising: a circulation device, a filtration mechanism, and a breeding pond. The filtration mechanism is disposed outside the circulation device, and the breeding pond is disposed outside the circulation device. The filtration mechanism includes a first inlet pipe, a filter box, a support, a first filter screen, a second filter screen, an adjusting component, a connecting rod, and a scraper. The first inlet pipe is connected to one end of the breeding pond, and the filter box is connected to the other end of the first inlet pipe. An installation groove is provided on the filter box, the support is installed inside the installation groove, the first filter screen is installed inside the support, the second filter screen is installed on the filter box, the adjusting component is installed on the outer wall of the filter box, the connecting rod is connected to the moving block of the adjusting component, the scraper is installed on the connecting rod, and a slag outlet is provided on the filter box.

[0007] In addition, the bullfrog farming recirculating water device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the circulation device is equipped with a mixing mechanism, which includes a connecting pipe, a mixing tank, a driving component, a rotating shaft, a stirring rod, a conveying component, a water outlet pipe, and a reagent tank. The connecting pipe is connected to one end of the filter box, and the mixing tank is connected to the other end of the connecting pipe. The driving component is installed at the top of the mixing tank, and the rotating shaft is connected to the output end of the driving component. The stirring rod is installed on the rotating shaft, the conveying component is installed inside the mixing tank, the water outlet pipe is connected to the water outlet end of the conveying component, and the reagent tank is installed on the outer wall of the mixing tank. A dosing port is provided on the reagent tank.

[0009] Specifically, the mixing tank is equipped with a cleaning assembly, which includes a second water inlet pipe, a fixing block, an annular spray pipe, and a nozzle. The second water inlet pipe is installed on the mixing tank, the fixing block is connected to one end of the second water inlet pipe, the annular spray pipe is installed on the fixing block, and the nozzle is fixed to the outer wall of the annular spray pipe.

[0010] Specifically, a valve is installed on the outer wall of the first inlet pipe, a slag collection box is installed on the outside of the slag outlet, and a handle is installed on the outer wall of the support.

[0011] Specifically, a sealing ring is fitted on the outer wall of the connecting pipe, and a closing cap is installed on the outer wall of the dosing port.

[0012] Specifically, an observation window is installed on the mixing tank 33.

[0013] Compared with existing technologies, this utility model has the following beneficial effects: The bullfrog farming recirculating water device of this utility model, through the design of the filtration mechanism, performs dual filtration treatment on the water discharged from the farming pond. The first and second filter screens can intercept impurities of different particle sizes, ensuring filtration effectiveness. Simultaneously, the adjusting component drives the connecting rod and scraper to move, periodically scraping away impurities on the first and second filter screens and discharging them through the slag outlet into the slag collection box. This achieves centralized collection and cleaning of impurities, effectively preventing their accumulation within the filtration device and ensuring a long-lasting and stable filtration effect.

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following describes an embodiment of the bullfrog breeding recirculating water device with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown in the figure, a bullfrog breeding recirculating water device according to an embodiment of the present invention includes: a circulation device 1, a filtration mechanism 2, and a breeding pond 5.

[0025] The filtration mechanism 2 is located outside the circulation device 1, and the aquaculture pond 5 is located outside the circulation device 1. The filtration mechanism 2 includes a first inlet pipe 21, a filter box 23, a bracket 25, a first filter screen 26, a second filter screen 27, an adjusting component 28, a connecting rod 29, and a scraper 210.

[0026] The first water inlet pipe 21 is connected to one end of the aquaculture pond 5, and the filter box 23 is connected to the other end of the first water inlet pipe 21. The filter box 23 has an installation groove 24, the bracket 25 is installed inside the installation groove 24, the first filter screen 26 is installed inside the bracket 25, the second filter screen 27 is installed on the filter box 23, the adjusting component 28 is installed on the outer wall of the filter box 23, the connecting rod 29 is connected to the moving block of the adjusting component 28, the scraper 210 is installed on the connecting rod 29, and the filter box 23 has a slag outlet 211.

[0027] It should be noted that the first filter screen 26 described in this embodiment has a large mesh design, mainly used to initially intercept larger solid impurity particles in the aquaculture circulating water, such as larger uneaten feed and fecal clumps, preventing these larger impurities from directly entering subsequent purification stages and causing blockages or affecting the purification effect. The second filter screen 27 has a small mesh, its function being to further refine the filtration of the circulating water after the initial filtration by the first filter screen 26, effectively intercepting smaller impurities, such as tiny uneaten feed debris, fine fecal particles, and some suspended solids.

[0028] It should be noted that the height of the aquaculture pond 5 described in this embodiment is higher than that of the filter box 23, so the water inside it can naturally flow into the filter box 23 through the first water inlet pipe 21 under the action of gravity.

[0029] It should be noted that the adjusting component 28 described in this embodiment is an electric slide.

[0030] Specifically, when the circulation device 1 starts working, the circulating water in the aquaculture pond 5 first flows into the filter box 23 through the first inlet pipe 21, and then passes through the first filter screen 26. Larger solid impurities are intercepted on the first filter screen 26. As the circulating water continues to flow in, these larger impurities gradually accumulate. At this time, the regulating component 28 starts working, and its output end drives the connecting rod 29 to move. When the circulating water device moves, it drives the scraper 210 to scrape the surface of the first filter screen 26, scraping the accumulated larger impurities towards the slag outlet 211. The circulating water that has undergone preliminary filtration by the first filter screen 26 continues to flow and reaches the second filter screen 27. The second filter screen 27 performs fine filtration on the circulating water, intercepting smaller impurities. The relatively clean circulating water after two stages of filtration flows out of the filter box 23 and enters the subsequent treatment stage. When it is necessary to replace the first filter screen 26 or the second filter screen 27, the operator only needs to hold the bracket 25 and apply pulling force to move it along the inner wall of the mounting groove 24 to pull out the first filter screen 26 for replacement.

[0031] In one embodiment of this application, such as Figure 4 As shown, the circulation device 1 is equipped with a mixing mechanism 3.

[0032] The mixing mechanism 3 includes a connecting pipe 31, a mixing tank 33, a driving component 34, a rotating shaft 35, a stirring rod 36, a conveying component 37, a water outlet pipe 38, and a reagent tank 39.

[0033] The connecting pipe 31 is connected to one end of the filter box 23, the mixing tank 33 is connected to the other end of the connecting pipe 31, the driving component 34 is installed at the top of the mixing tank 33, the rotating shaft 35 is connected to the output end of the driving component 34, the stirring rod 36 is installed on the rotating shaft 35, the conveying component 37 is installed inside the mixing tank 33, the water outlet pipe 38 is connected to the water outlet end of the conveying component 37, the medicine tank 39 is installed on the outer wall of the mixing tank 33, and the medicine tank 39 is provided with a dosing port 310.

[0034] It should be noted that the driving component 34 described in this embodiment is a motor.

[0035] It should be noted that the conveying component 37 described in this embodiment is a water pump.

[0036] Specifically, after the relatively clean circulating water, filtered by the filtration mechanism 2, flows into the mixing tank 33 through the connecting pipe 31, the staff first adds an appropriate amount of purification agent or nutrient agent needed for breeding into the agent tank 39 through the dosing port 310. The agent in the agent tank 39 flows into the mixing tank 33 under the action of gravity. Then, the drive unit 34 is activated, and the rotating shaft of the drive unit 34 drives the rotating shaft 35 to rotate. The stirring rod 36 on the rotating shaft 35 rotates accordingly, which fully stirs and mixes the circulating water and agent in the mixing tank 33, so that the agent can be evenly dispersed in the circulating water for better purification. After the stirring and mixing is completed, the conveying unit 37 is activated. The conveying unit 37 transports the evenly mixed circulating water back to the breeding pond 5 through the outlet pipe 38, providing a suitable water quality environment for bullfrog breeding.

[0037] In one embodiment of this application, such as Figure 5 As shown, a cleaning component 4 is installed inside the mixing tank 33.

[0038] The cleaning assembly 4 includes a second water inlet pipe 41, a fixing block 42, an annular spray pipe 43, and a spray head 44.

[0039] The second water inlet pipe 41 is installed on the mixing tank 33, the fixing block 42 is connected to one end of the second water inlet pipe 41, the annular spray pipe 43 is installed on the fixing block 42, and the nozzle 44 is fixed to the outer wall of the annular spray pipe 43.

[0040] Understandably, when cleaning the inside of the mixing tank 33 is required, the workers first connect an external clean water source to the second inlet pipe 41. The clean water flows through the second inlet pipe 41 into the annular spray pipe 43, and then is evenly sprayed onto the inner wall of the mixing tank 33 from the nozzles 44. Since the nozzles 44 are fixed to the outer wall of the annular spray pipe 43 and are distributed at a certain angle, they can thoroughly rinse the inner wall of the mixing tank 33, washing away any residual chemicals, impurities, etc. The wastewater after rinsing is discharged through the drain outlet at the bottom of the mixing tank 33, thus completing the cleaning of the inside of the mixing tank 33.

[0041] In one embodiment of this application, such as Figure 2 As shown, a valve 22 is installed on the outer wall of the first water inlet pipe 21, a slag collection box 212 is installed on the outside of the slag outlet 211, and a handle 213 is installed on the outer wall of the bracket 25.

[0042] It should be noted that the valve 22 described in this embodiment allows staff to flexibly adjust the amount of circulating water entering the filter box 23 to meet the aquaculture needs under different conditions. The slag collection box 212 installed outside the slag outlet 211 can effectively collect larger solid impurity particles scraped off the first filter screen 26, preventing these impurities from scattering in the surrounding environment, maintaining the cleanliness and hygiene of the work area, and facilitating the subsequent centralized treatment of these impurities. The handle 213 installed on the outer wall of the bracket 25 provides convenience for staff when replacing the first filter screen 26 or the second filter screen 27. Staff can easily grasp the handle 213 and pull the bracket 25 along the mounting groove 24 to smoothly remove the first filter screen 26 for replacement, making the operation more convenient and faster, and improving work efficiency.

[0043] In one embodiment of this application, such as Figure 4 As shown, a sealing ring 32 is fitted on the outer wall of the connecting pipe 31, and a closing cap 311 is installed on the outer wall of the dosing port 310.

[0044] It should be noted that the sealing ring 32 fitted on the outer wall of the connecting pipe 31 can effectively prevent leakage at the connection between the connecting pipe 31 and the mixing tank 33. The closing cover 311 installed on the outer wall of the dosing port 310 can tightly seal the dosing port 310 when it is not necessary to add chemicals to the chemical tank 39, preventing external dust, impurities, etc. from entering the chemical tank 39 and contaminating the chemicals, ensuring the purity of the chemicals, and thus ensuring the subsequent purification effect on the circulating water.

[0045] In one embodiment of this application, such as Figure 1 As shown, an observation window 6 is installed on the mixing tank 33.

[0046] Understandably, the observation window 6 allows staff to directly observe the mixing of circulating water and chemicals inside the mixing tank without opening the mixing tank 33.

[0047] Working principle: When the circulation device 1 starts working, the circulating water in the aquaculture pond 5 first flows into the filter box 23 through the first inlet pipe 21, and then passes through the first filter screen 26. Larger solid impurities are intercepted on the first filter screen 26. As the circulating water continues to flow in, these larger impurities gradually accumulate. At this time, the regulating component 28 starts working, and its moving block drives the connecting rod 29 to move, which in turn causes the scraper 210 to scrape the surface of the first filter screen 26, scraping the accumulated larger impurities toward the slag outlet 211. The circulating water that has undergone preliminary filtration by the first filter screen 26 continues to flow and reaches the second filter screen 27. The second filter screen 27 performs fine filtration on the circulating water, intercepting smaller impurities. The relatively clean circulating water after two stages of filtration flows out of the filter box 23 and enters the subsequent treatment stage. When it is necessary to replace the first filter screen 26 or the second filter screen 27, the operator only needs to hold the filter. After the relatively clean circulating water, filtered by the filtration mechanism 2, flows into the mixing tank 33 through the connecting pipe 31, the operator first adds an appropriate amount of purification agent or nutrient agent required for aquaculture into the agent tank 39 through the dosing port 310. The agent in the agent tank 39 flows into the mixing tank 33 under the action of gravity. Then, the drive unit 34 is activated, which drives the rotating shaft 35 to rotate. The stirring rod 36 on the rotating shaft 35 rotates accordingly, which fully stirs and mixes the circulating water and agent in the mixing tank 33, so that the agent can be evenly dispersed in the circulating water for better purification treatment. After mixing is complete, the conveyor 37 is activated, which transports the uniformly mixed circulating water back to the breeding pond 5 through the outlet pipe 38, providing a suitable water quality environment for bullfrog farming. When cleaning the inside of the mixing tank 33 is required, the staff first connects the external clean water source to the second inlet pipe 41. The clean water flows into the annular spray pipe 43 through the second inlet pipe 41, and then is evenly sprayed onto the inner wall of the mixing tank 33 from the nozzles 44. Since the nozzles 44 are fixed to the outer wall of the annular spray pipe 43 and are distributed at a certain angle, they can thoroughly rinse the inner wall of the mixing tank 33, washing away any residual agents, impurities, etc. The wastewater after rinsing is discharged through the drain outlet at the bottom of the mixing tank 33, thus completing the cleaning of the inside of the mixing tank 33.

[0048] The bracket 25 pulls out the first filter 26 along the mounting groove 24 for replacement.
