Description

Technical Field

[0001] This utility model relates to the field of biological laboratory technology, specifically to a waste treatment device for biological laboratories. Background Technology

[0002] Biological experiments refer to the process of purposefully observing and studying the structure and life activities of organisms that are not easily observed under normal circumstances, using certain instruments, materials and reagents under specific environmental conditions and through scientific methods. Biology is a natural science based on experiments. Through biological experiments, students can not only understand the concepts and laws of biology and truly learn the basic knowledge of biology, but also be encouraged to think actively, be trained in scientific methods, and cultivate their scientific literacy.

[0003] Prior art 1 (application number: CN202322127050.3) discloses a laboratory waste treatment device, comprising: a waste liquid tank, a waste container fixedly connected to the outer wall of the waste liquid tank, a rotating plate rotatably connected to the top of the waste liquid tank via a hinge, a rack fixedly connected to the bottom of the connecting seat, a gear meshing with the outer wall of the rack, a support frame fixedly installed on the outer wall of the waste container, a sliding plate slidably connected to the inner wall of the support frame, and a connecting plate fixedly connected to the top of the sliding plate. This invention, by installing a storage tank, allows a servo motor to rotate clockwise, causing the gear to rotate upwards and pushing the rotating plate to rotate clockwise, thus exposing the top of the storage tank. Conversely, the servo motor rotates in the opposite direction, causing the rack to pull the rotating plate counterclockwise, facilitating sealing of the top of the storage tank and preventing odor diffusion. An extension rod, through the connecting plate, pushes the sliding plate to the right, sealing the feeding port and preventing the diffusion of dust or odors generated during laboratory waste disposal.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above-mentioned laboratory waste treatment device: the waste generated during the raising of organisms is inconvenient to collect and deodorize in a unified manner, and it is also inconvenient to automatically add feed and start feeding. The deodorization inside the device is easy to spread and easily pollute the laboratory environment. Utility Model Content

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Please see Figures 1-5 This utility model provides a technical solution for a waste treatment device for biological laboratories, including a base 1, a ventilation fan 2, a food container 3, a feed pipe 4, a water pipe 5, a placement box 6, a glass cover 7, a shielding cloth 8, a grid 9, a rotating shaft 10, a partition 11, a limiting cylinder 12, a drainage trough 13, a control structure 14, a hollow block 1401, a pull rope 1402, a pulley body 1403, a buoyancy block 1404, a feces collection trough 15, a filter screen 16, and a glass cover 17.

[0033] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 2 As shown, the upper and left ends of the glass cover 7 are covered with a shielding cloth 8, and a glass cover plate 17 is fitted onto the upper end of the glass cover 7. The upper left end of the base 1 is inclined, and the interior of the base 1 is hollow. A manure collection trough 15 is connected through the left end of the base 1. The depth of the manure collection trough 15 is smaller than the distance between the lower end of the filter screen 16 and the lower end of the base 1. The feeding box 6 is connected to the feeding box 3 through the feed pipe 4 and the water pipe 5. The lower end of the water pipe 5 is flush with the lower rear end of the feeding box 3, and the lower front end of the feeding box 3 is inclined. The glass cover 17 is used to place the organism on the grid 9. According to the needs of the biological experiment, the shielding cloth 8 is pushed to cover the glass cover 7 to block the light. The power switch of the ventilation fan 2 is turned on, and the ventilation fan 2 replaces the air in the base 1. The air is filtered through the filter screen 16 to remove odors and prevent the odor from spreading and polluting the environment. At the same time, the feed for the organism is placed in the front groove of the placement box 6, and the water source for the organism is placed in the rear groove of the placement box 6. The feed is put into the front groove of the food box 3 through the feed pipe 4, and the water source is injected into the rear groove of the food box 3 through the water pipe 5.

[0034] Combination Figure 1 and Figure 3 As shown, the middle longitudinal section of the feed tube 4 has a circular structure, and the feed tube 4 is rotatably connected to a rotating shaft 10. A partition 11 is fixedly connected to the outer surface of the rotating shaft 10 at equal angles. At the same time, the outer surface of the partition 11 is fitted to the arc-shaped inner wall of the feed tube 4. The lower end of the feed tube 4 is inclined and has an "L"-shaped structure. When the feed in the food box 3 is insufficient, rotating the rotating shaft 10 drives the partition 11 to rotate, thereby facilitating the transfer of feed down through the feed tube 4 to the food box 3. This makes it convenient for the feed to be consumed at the biological copper tube food box 3, preventing the feed outlet from connecting to the outside, maintaining a sealed environment, and facilitating use.

[0035] Combination Figure 1 , Figure 4 and Figure 5 As shown, the control structure 14 includes a hollow stop block 1401, a pull rope 1402, a pulley body 1403, and a buoyancy block 1404. The upper end of the hollow stop block 1401 is fixedly connected to the pull rope 1402. The movable end of the pull rope 1402 passes through the pulley body 1403 and is fixedly connected to the buoyancy block 1404. The pulley body 1403 is rotatably connected to the upper end face of the placement box 6. The hollow stop block 1401 passes through the interior of the limiting cylinder 12, and the hollow stop block 1401 and the limiting cylinder 12 are engaged. At the same time, a drainage groove 13 is provided on the outer surface of the limiting cylinder 12, and the height of the drainage groove 13 is not greater than the height of the hollow stop block 1401. When the water in the food box 3 is insufficient, the buoyancy block 1404 moves downward along with the pull rope 1402. The buoyancy block 1404 is connected to the hollow stop block 1401 through the pull rope 1402. Under the action of the pulley body 1403, it forms a fixed pulley. Thus, when the buoyancy block 1404 moves downward, the hollow block 1401 moves upward and is subjected to an upward pulling force. The hollow block 1401 moves upward inside the limiting cylinder 12. The hollow block 1401 and the drainage channel 13 are not covered, so that the water can flow into the water pipe 5 through the drainage channel 13 and then into the food container 3. When the water is full, the buoyancy block 1404 is subjected to the buoyancy of the water. The buoyancy of the water and the weight of the buoyancy block 1404 are equal. At this time, the buoyancy block 1404 no longer pulls the hollow block 1401 downward. The hollow block 1401 moves downward in the limiting cylinder 12 under its own weight, thereby blocking the drainage channel 13 and blocking the water flow into the drainage pipe 5, thus completing the purpose of automatic water filling. This is the working process of the waste treatment device for biological laboratories.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
