Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of biological hazardous waste treatment, and particularly relates to a biological hazardous waste treatment device, which is mainly used for treating animal carcasses after biological experiments in biological laboratories. BACKGROUND

[0002] Biochemical hazardous waste is a kind of special pollutants, and although the total amount of the waste is not large compared with various solid wastes, the waste is one of the sources of transmission of harmful bacteria and viruses and one of the pollution sources of various infectious diseases and pestilence.

[0003] The biochemical hazardous waste treatment device is mainly used for treating biological carcasses and biological bodies in biological laboratories after biological experiments. The biochemical hazardous waste treatment device generally performs crushing, high-temperature and high-pressure sterilization and disinfection treatment on biological carcasses. After incineration treatment, the biochemical hazardous waste can not only kill bacteria and convert most of the organic matters into inorganic matters, but also can reduce the volume of the biochemical hazardous waste by 85%-95%, thereby greatly reducing the cost of final landfill and truly achieving harmless and reduced disposal of medical waste.

[0004] The existing biochemical hazardous waste treatment device has the following shortcomings:

[0005] 1) The existing biochemical hazardous waste treatment device needs to perform high-temperature and high-pressure sterilization and disinfection, and the high-temperature and high-pressure gas is directly discharged after sterilization and filtration, which not only causes waste of energy, but also causes waste of energy due to the high temperature of the gas discharged by the pressure container. The waste liquid of the pressure container contains a large amount of water, and direct discharge also causes waste of resources. Moreover, the existence of high-temperature gas greatly hinders the vacuum pumping, and the vacuum pump cannot effectively pump the pressure container in the high-temperature gas, which seriously affects the vacuum pumping effect of the pressure container, prolongs the vacuum pumping time of the pressure container, and affects the operation efficiency of the device.

[0006] 2) Most of the existing biochemical hazardous waste treatment devices do not have a weighing function, and a weighing scale needs to be additionally provided for weighing operation. On the one hand, the operation is not convenient, and on the other hand, the weighing result needs to be manually input into the device, which greatly reduces the work efficiency and is prone to input errors, thereby affecting the use of the device.

[0007] 3) The existing biological hazardous waste treatment pressure container has poor sealing effect, cannot meet the requirements of biological hazardous waste treatment at the same time, and cannot meet the requirements of biological hazardous waste treatment; in particular, on the one hand, the top of the biological hazardous waste treatment pressure container is provided with a pressing unit, so that the sealing problem between the trapezoidal screw shaft and the upper sealing cover needs to be considered; on the other hand, the crushing unit is arranged in the pressing cylinder in the biological hazardous waste treatment pressure container, so that the sealing problem between the input shaft of the crusher and the pressing cylinder mounting hole needs to be considered.

[0008] 4) Most of the existing biological hazardous waste treatment devices do not have a pressing mechanism, so that the biological hazardous waste is easily stuck in the feeding port and cannot smoothly or completely enter the crushing mechanism below the feeding port, so that the operation is not smooth and the stability is poor, and manual pressing operation is required to solve the blocking problem, so that the rotating crusher is easy to cause injury to the operator, so that the blocking problem needs to be solved.

[0009] 5) The existing biological hazardous waste treatment device causes a large amount of residual material to adhere to the shredder after the shredder is operated, so that manual high-pressure water gun washing operation is required, which greatly increases the labor intensity of the operator, and on the other hand, due to the open type operation, the residual material is easy to spread everywhere, and the smell is easy to spread everywhere, which affects the surrounding environment.
