Description

Technical Field

[0001] This invention belongs to the field of zooplankton sample processing technology, specifically relating to a pretreatment device for zooplankton samples. Background Technology

[0002] Zooplankton is a general term for heterotrophic invertebrates and chordate larvae that frequently float in water and cannot produce organic matter themselves. They are a group of animals that live a planktonic life in water. They either have no swimming ability at all or have a very weak swimming ability. They cannot move long distances and are not strong enough to resist the current of water. When processing zooplankton samples, a pretreatment device is used. Traditional pretreatment devices include structures such as fixed containers, bases, fixed seats, and filters. The advantage of this pretreatment device is that it can remove formaldehyde and impurities from zooplankton samples. However, traditional pretreatment devices have a relatively simple structure, which results in poor cleaning of zooplankton samples and is not conducive to subsequent processing of zooplankton samples. Improvement is urgently needed. Summary of the Invention

A limiting frame 35, slidably connected to the second limiting transmission plates 31, is disposed below the limiting mounting plate 34. The third limiting transmission plates 37 and the limiting frame 35 are slidably connected. A first driving plate 30, which is an electromagnetic plate, is fixedly connected to the lower surface of the second limiting transmission plates 31.

The lower surface of the first drive plate 30 is provided with an elastic noise reduction plate 32 for noise reduction. The elastic noise reduction plate 32 is a silicone plate. In use, the elastic noise reduction plate 32 prevents the first drive plate 30 and the second drive plate 33 from colliding and making abnormal noise, thereby reducing noise and protecting the first drive plate 30 and the second drive plate 33. The bottom of the limiting frame 35 is provided with several elastic support members 36 for supporting the second limiting transmission plate 31. The elastic support members 36 are metal springs. In use, the elastic support members 36 vibrate the second limiting transmission plate 31.

[0026] The working principle and usage process of this invention: When in use, remove the detachable cover plate 214 and pour the zooplankton sample (hereinafter referred to as the sample) into the uppermost filter box 222. At this time, use a water pipe to inject water from the top of the filter box 222 into the interior of the filter box 222, thereby achieving rapid rinsing of the sample. During the rinsing process, the filter box 222 vibrates vertically due to the intermittent mutual repulsion between the first drive plate 30 and the second drive plate 33. The wastewater is stored in the storage tank 217 and discharged through the drain pipe 216. Meanwhile, through the cooperation of the first driver 210 and the second driver 218, the two adjacent filter boxes 222 are driven to rotate slightly in opposite directions (for example, the rotation angle is 10° or 20°, as long as the sample can fall normally into the lower filter box 222 without spilling out during the rotation). This causes the filter box 222 to move horizontally and vertically at the same time, so that the sample in the filter box 222 keeps changing position, achieving thorough cleaning of the sample. Furthermore, through the vertical and horizontal reciprocating movement of the filter box 222, the filter screen 224 quickly sieves the sample, thereby achieving rapid grading of the sample. Different grades of samples are stored in different filter boxes 222. When a user needs to sample the sample in the filter box 222, the first driver 210 and the second driver 218 work together to drive the two adjacent filter boxes 222 to rotate in opposite directions, so that the two adjacent filter boxes 222 are arranged in an alternating manner. At this time, the user can directly sample the sample in the filter box 222, making it more convenient for the user to perform graded sampling of the sample. Thus, through the cooperation of multiple structures, thorough cleaning and multi-level classification of zooplankton samples can be achieved, facilitating subsequent processing of zooplankton samples by users. Secondly, this invention makes it easier for users to collect zooplankton samples, making the pretreatment device more user-friendly. Furthermore, this invention has a simple structure and is easy to use, making it worthy of promotion and application.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
