Description

Technical Field

[0001] The utility model relates to the technical field of recycling devices, in particular to a waste recycling device used in a biological analysis laboratory. Background Art

[0002] The bioanalysis laboratory is a place for experiments related to biology. As the requirements for quality control become more and more stringent, the demand for a constant temperature and humidity environment is increasing, and the application field is becoming wider and wider. Generally, schools and hospitals will have bioanalysis laboratories. By studying and learning about organisms in the bioanalysis laboratory, a large amount of waste will be generated in the process of studying organisms in the biological laboratory. If the waste is discharged at will, it may cause pollution to the surrounding environment. Generally, the waste generated in the bioanalysis laboratory is recovered through a waste recovery device, and then discharged after treatment.

[0005] However, the patent still has the following problems: when the device recycles waste, the solid waste will enter the recovery chamber together with the liquid waste after cutting and crushing, which will cause the device to be unable to achieve solid-liquid separation. The treatment of mixed solid-liquid waste will be more complicated and time-consuming, because the solid impurities in the liquid may clog the filtration system, reduce the filtration speed, and increase the treatment cycle. At the same time, many regions have strict regulations on laboratory waste treatment, requiring that waste liquid must be fully treated before discharge, including solid-liquid separation. This will require more time for subsequent treatment of the waste and make it difficult to meet usage needs. Utility Model Content

[0024] After the waste enters the waste collection box 1 through the feed port 2, the waste can fall onto the surface of the conveyor belt 4. At this time, the first motor 14 will drive the right drive shaft 3 to rotate, so that the conveyor belt 4 can drive the left drive shaft 3 to rotate at the same time. In this process, the push plate 5 can push the waste on the surface of the conveyor belt 4 to move toward the left, and the liquid mixed in the waste can directly fall into the liquid storage box 12 through the water hole 6, so as to achieve the preliminary solid-liquid separation of the waste, and the waste pushed down by the push plate 5 can fall onto the top of the grid plate 8, and the waste will accumulate on the surface of the grid plate 8, and the rotating shaft 9 can use the cutting knife 10 to cut the waste when rotating.
