Description

Technical Field

[0001] This utility model belongs to the technical field of vaccine production equipment, and in particular relates to a tissue wetting device with sedimentation function. Background Technology

[0002] In the vaccine production cycle, SPF animals are usually used. SPF (Specific Pathogen Free) animals are laboratory animals that do not carry major potential infectious agents or conditional pathogens or pathogens that would greatly interfere with scientific experiments, except for pathogens that should be excluded from clean animals.

[0003] In the fields of laboratory animal research, breeding, and quarantine, animal tissues require pretreatment to clean them and remove impurities. Currently, animal tissue pretreatment primarily employs methods such as manual cleaning, mechanical brushing, and rotary drum cleaning, using cleaning solutions to remove soluble impurities from the surface or interior of the tissues. Manual cleaning involves manual stirring and rubbing; mechanical brushing uses a cleaning brush to scrub the tissues placed on a flat surface; and rotary drum cleaning involves rotating a cleaning drum on a flat surface.

[0004] However, the aforementioned manual cleaning methods are not only labor-intensive and inefficient, but also pose a risk of introducing other impurities due to the open cleaning environment. Mechanical brushing and rotary drum cleaning, on the other hand, suffer from insufficient cleaning effectiveness due to their limited modes, and some tissue blocks float on the liquid surface during cleaning, resulting in poor cleaning results. Furthermore, after the soaking and cleaning process, workers need to manually retrieve the tissue blocks, making the operation cumbersome. In addition, the cleaning solution in existing technologies is directly discharged after cleaning, leading to a significant waste of resources. Therefore, there is an urgent need to design a tissue soaking device with sedimentation function to solve the above problems. Summary of the Invention

[0005] This invention provides a tissue wetting device with a reasonable structural design and sedimentation function to solve the technical problems existing in the prior art. This invention ensures that the tissue block is completely submerged in the cleaning solution for better soaking and cleaning. It can automatically retrieve the tissue block after the soaking and cleaning operation is completed, and the cleaning solution can be recycled, avoiding resource waste.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A tissue soaking device with sedimentation function includes a support, on which a soaking and cleaning tank, a sedimentation tank, and a drying tank are installed; an ultrasonic component is installed on the soaking and cleaning tank, a lifting drive component is arranged on the outside of the soaking and cleaning tank, a lifting seat structure is installed on the moving end of the lifting drive component, a perforated seat plate is fixedly connected to the lifting seat structure, and a water-permeable container is detachably connected to the perforated seat plate; a filter screen assembly is inserted in the sedimentation tank to divide the inner cavity of the sedimentation tank into a sedimentation chamber and a settling chamber. The clarification chamber also includes a sedimentation conveying pipeline structure connected to the inner cavity of the soaking and cleaning tank and the sedimentation chamber; an overflow box installed in the inner cavity of the soaking and cleaning tank, with an overflow port on the upper side wall of the overflow box; a filter basket installed in the inner cavity of the overflow box; a return pipeline structure, with the inlet of the return pipeline structure extending into the clarification chamber and the outlet extending into the filter basket; a drainage pipeline structure connected to the inner cavity of the sedimentation tank and the inner cavity of the soaking and cleaning tank; a drying cover installed at the opening of the drying tank; and a drying assembly for heating the inner cavity of the drying tank.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a tissue immersion device with a sedimentation function. The permeable container is used to hold tissue blocks, ensuring that when the container is submerged in the cleaning solution, the tissue blocks are bound within it, preventing some tissue blocks from floating in the liquid and affecting the cleaning effect. The ultrasonic component allows for rapid and efficient cleaning of the tissue blocks immersed in the cleaning solution in the soaking tank. The lifting seat structure and lifting drive component automatically immerse the permeable container and its tissue blocks in the cleaning solution. After cleaning, the permeable container and the tissue blocks within it can be lifted above the liquid surface for draining, eliminating the need for manual retrieval. This simple and time-saving operation saves time and effort. A drying tank and drying components allow for drying of the cleaned tissue blocks. A sedimentation conveying pipeline and sedimentation tank allow for sedimentation of the cleaning solution, and a return pipeline allows for the return of the clarified solution to be reused in an immersion cleaning tank. A filter assembly and filter basket further filter the clarified solution. This invention ensures complete immersion of the tissue blocks in the cleaning solution for optimal soaking and cleaning. The tissue blocks can be automatically retrieved after immersion cleaning, and the cleaning solution can be recycled, preventing resource waste.

[0030] Working principle: In actual operation, the tissue block to be cleaned is placed in the permeable container 8 and installed on the corresponding hollow base plate 30. Then, the drive motor 10-2 is started to drive the sprocket transmission pair 10-10, thereby immersing the permeable container 8 and the tissue block inside it into the cleaning solution in the soaking and cleaning tank 7. After soaking the tissue block for a period of time, the ultrasonic generator is turned on to generate a high-frequency oscillation signal through the ultrasonic signal generator, which is converted into a high-frequency mechanical oscillation of tens of thousands of times per second through the transducer 6, so as to quickly clean the tissue block in the cleaning solution. After the predetermined cleaning time, the drive motor 10-2 is started again to lift the permeable container 8 and the tissue block inside it to the top of the cleaning solution. After draining for a period of time, the permeable container 8 is removed and the permeable container 8 and the tissue block inside it are transferred to the drying tank 12. The hot air generated by the drying component is used to dry the tissue block that has been cleaned and drained. After the drying operation is completed, the permeable container 8 and the tissue block inside it are taken out for subsequent use. After working for a period of time, the cleaning solution in the soaking and cleaning tank 7 is recycled. This is done by opening the solenoid valve 27 on the sedimentation outlet pipe 31 and the sedimentation delivery pipe 1, closing the solenoid valve 27 on the drain pipe 4, and turning on the sedimentation discharge pump 3 to discharge the cleaning solution in the soaking and cleaning tank 7 into the sedimentation chamber 19. After sedimentation for a period of time, the return pump 2 and the solenoid valve 27 installed on the return water delivery pipe 21 and the water delivery pipe 25 are turned on to discharge the clarified cleaning solution after sedimentation into the overflow tank 28. The solution then flows into the soaking and cleaning tank 7 for reuse through the overflow port 29 on the overflow tank 28. The clarified cleaning solution can be further filtered by the filter screen assembly 24 and the filter basket 26.
