Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment, and in particular relates to a mechanical water filtering device for experiments. Background Art

[0002] Laboratory animals are essential experimental subjects in life science research. In recent years, zebrafish have become highly sought-after due to their unique biological characteristics, experimental advantages, and wide range of applications. As an aquatic model organism, zebrafish are subject to significant influence from water parameters such as temperature, pH, and conductivity. To meet experimental requirements, the breeding process of zebrafish requires continuous interception of suspended particulate matter to ensure clean water quality and provide a healthy, stable living environment for the zebrafish. Therefore, water regulation plays a crucial role in the stability and reliability of experimental results.

[0003] The filtration module of the zebrafish water circulation system must also have a filter to filter the water to remove suspended particles generated during the zebrafish breeding process and ensure the cleanliness of the water in the breeding tank. The filter is generally a filter cotton, which needs to be replaced regularly to ensure the cleanliness of the water in the breeding tank. In the existing technology, although the use of a rotary drum filter can filter the water, it is large in size, has low flexibility, and is cumbersome to install and operate, making it difficult to use in experimental equipment. In addition, there are many types of filtration devices in the existing water circulation system, which have problems such as frequent replacement of consumables, low filtration efficiency, and incomplete filtration of suspended particles in the water.

[0004] For example, the Chinese utility model patent with authorization announcement number CN 221626051 U discloses a filtering device for water treatment and restoration experiments, which passes water from a water supply pipe into a sedimentation tank. Solid impurities in the water are precipitated in the sedimentation tank and discharged into the filter tank from the drain hole. The gate is then opened to discharge the water into the restoration activation tank. The water is treated and restored using activated carbon and soluble minerals in two treatment frames. However, its shortcomings are: the filtration process is cumbersome, the structure is complex, and it occupies a large space. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mechanical water filtering device for experiments.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This utility model integrates the driving mechanism, flushing mechanism and filtering mechanism into one box, thus achieving a compact layout, reducing space occupancy, simplifying the installation process and improving the overall operating efficiency of the equipment;

[0016] 2. By directly connecting the filter to the water inlet pipe and the sewage pipe, the water flow path is made more direct, which reduces the pressure loss during water flow, improves the filtration efficiency, and also makes it easier to maintain and clean the filter;

[0017] 3. The design of the water inlet turntable and the drain turntable combined with the keel to support the filter not only enhances the structural stability of the filter, but also enables the filter to be evenly stressed, reducing the risk of deformation or damage due to long-term use, while facilitating the replacement and maintenance of the filter;

[0018] 4. The sewage collecting tank is convenient for collecting impurities generated during the filtration process. The inclined setting and the flushing effect of the nozzle ensure that the impurities can be effectively removed, prevent clogging, reduce maintenance frequency, and extend the service life of the equipment;

[0019] 5. The externally accessible flushing mechanism allows users to flexibly flush the filter as needed, improving the flexibility and practicality of the equipment. At the same time, the nozzle is directly aimed at the part that needs to be cleaned, ensuring the effectiveness of the flushing and reducing water waste;

[0020] 6. The design of the disassembly and assembly port and top cover facilitates regular inspection and maintenance. Internal parts can be accessed without disassembling the entire device, simplifying the maintenance process and saving time and costs.

DETAILED DESCRIPTION

[0027] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1 As shown, an experimental mechanical water filtration device includes a box body 1 with an opening at the bottom, wherein a driving mechanism, a flushing mechanism and a filtering mechanism connected to the driving mechanism are arranged inside the box body 1, and the filtering mechanism includes a rotary drum filter, and the two ends of the rotary drum filter are respectively connected to a water inlet pipe 3 and a sewage pipe 4.

[0030] Example 2:

[0031] like Figure 2-4As shown, an experimental mechanical water filtration device is different from Example 1 in that the rotary drum filter includes a filter screen 5, and card plates 11 for connecting and fixing are provided on both sides of the connection of the filter screen 5. The filter screen 5 forms a filtration barrier between the inner cavity of the rotary drum filter and the outside world. The inner cavity of the filter screen 5 is connected to the water inlet pipe 3 and the sewage pipe 4 respectively.

[0032] Furthermore, the rotary drum filter also includes an inlet turntable 12 and a drain turntable 13. The inlet turntable 12 is rotatably connected to the water inlet pipe 3 through a bearing 15, and the drain turntable 13 is rotatably connected to the sewage pipe 4 through a bearing 15. One or more keels 14 are arranged between the water inlet turntable 12 and the drain turntable 13. The filter net 5 is in a circular shape and is wrapped around the outside of the keel 14.

[0033] Specifically, the water inlet turntable 12 and the drainage turntable 13 have the same diameter and are provided with a circular ring smaller than the maximum outer diameter on the opposite side. The circular ring is provided with T-shaped grooves 19 arranged circumferentially at the same angle. Several keels 14 are arranged circumferentially at the same angle and are clamped in the T-shaped grooves 19 on the water inlet turntable 12 and the drainage turntable 13 to achieve the same angle rotation of the water inlet turntable 12 and the drainage turntable 13.

[0034] Furthermore, the driving mechanism includes a driving gear 8, a driven gear 10 and a servo motor 7 mounted on the side wall of the box body 1, the driving gear 8 is mounted on the output shaft of the servo motor 7, the driven gear 10 is mounted on the rotating shaft 6 on the water inlet turntable 12, and the driving gear 8 and the driven gear 10 are meshed and transmitted to each other. The speed and frequency of the rotary drum filter are controlled by the meshing transmission of the driving gear 8 and the driven gear 10.

[0035] Furthermore, the inner cavity of the filter screen 5 is provided with a dirt collecting trough 16, which is arranged obliquely at the inlet of the sewage pipe 4, and the spray direction of the nozzle 9 is toward the dirt collecting trough 16. The dirt collecting trough 16 is designed to better collect impurities and ensure that they can be discharged smoothly through the sewage pipe 4 to avoid blockage. At the same time, the dirt collecting trough 16 is arranged obliquely at the inlet of the sewage pipe 4, ensuring that impurities can be discharged smoothly by gravity and water flow.

[0036] Furthermore, the flushing mechanism includes a flushing pipe joint 17 provided on the outer side wall of the box body 1 , a flushing pipe 18 threadedly connected to the flushing pipe joint 17 , and a nozzle 9 , wherein the nozzle 9 is installed on the flushing pipe 18 .

[0037] Furthermore, a disassembly opening is provided at the upper end of the box body 1, and a top cover 2 for disassembly, assembly and sealing is installed on the disassembly opening.

[0038] The working principle of this utility model is:

[0039] When the experimental mechanical water filtering device starts working, the servo motor 7 is started, and the output shaft of the servo motor 7 drives the driving gear 8 to rotate. Since the driving gear 8 is engaged with the driven gear 10 installed on the rotating shaft 6 on the water inlet turntable 12, the driven gear 10 will rotate accordingly, thereby driving the water inlet turntable 12 and the entire rotary drum filter connected thereto to rotate together; the sewage to be treated enters the inner cavity of the filter screen 5 through the water inlet pipe 3, and the sewage passes through the filter screen 5 to complete the separation of water and suspended particulate matter. Under the action of gravity, the clean water falls from the bottom of the filter screen 5 to the bottom of the box body 1, and the suspended particulate matter remains on the inner side of the filter screen 5.

[0040] During the filtration process, impurities will accumulate on the inner surface of the filter screen 5. In order to maintain the filtration efficiency, a flushing mechanism is set up to remove these impurities. When the filter screen 5 needs to be cleaned, high-pressure water flow or air flow can be injected into the flushing pipe 18 through the flushing pipe joint 17. The high-pressure fluid will be sprayed into the inner cavity of the filter screen 5 through the nozzle 9, especially into the sewage collection tank 16, to help flush the suspended particulate matter attached to the upper side of the inner wall of the filter screen 5 into the sewage collection tank 16, and finally discharged out of the device through the sewage pipe 4.

[0041] In addition, a disassembly port is provided on the top of the box body 1 and a top cover 2 is installed to facilitate inspection, maintenance or replacement of internal components. When maintenance is required, the top cover 2 can be opened to facilitate access to various components inside the box body 1.

[0042] In summary, the mechanical water filtration device used in this experiment realizes the automatic water filtration and self-cleaning functions through the rotating filtration mechanism and the flushing mechanism, which improves the filtration efficiency and reduces the need for manual intervention.
