TECHNICAL FIELD
[0001] The utility model relates to the technical field of breeding sanitation and epidemic prevention, and particularly relates to an experimental animal dirt treatment device. BACKGROUND
[0002] The experimental animal dirt treatment device is a very important part of experimental animal facilities, and its main purpose is to ensure that waste, sewage, waste gas and the like generated during experiments are effectively treated to prevent environmental pollution and potential biological hazards.
[0003] In the daily feeding process of experimental animals, a large amount of feces and urine will inevitably be produced. If these excretions are not cleaned in time, not only will the feeding environment be polluted, but also they may become a medium for disease transmission. However, the traditional manual cleaning method has many inconveniences. First of all, low efficiency is a significant problem: the staff need to frequently enter the cage to clean, which not only increases the labor intensity, but also reduces the work efficiency. Secondly, since the operator directly contacts the animals and their excretions, the operator faces a high risk of infection of pathogenic microorganisms, which poses a potential threat to personal health.
[0004] On the other hand, although it is possible to consider using a pipeline system to automatically discharge these wastes to improve efficiency and reduce safety hazards caused by human intervention, this method also has its limitations. In particular, when it comes to animal feces containing a lot of undigested plant fibers (such as rodents), such substances are very easy to cause pipeline blockage. Once blockage occurs, not only will it affect the normal operation of the entire drainage system, but it may also lead to more serious hygiene problems, such as sewage backflow, etc. Therefore, when designing experimental animal facilities, how to balance the contradiction between automatic treatment and prevention of blockage has become a technical problem to be solved. SUMMARY
