Grinding disc type efficient crushing device for plastic syringe type medical waste

Abstract

The invention discloses a grinding disc type efficient crushing device for plastic syringe type medical waste. The grinding disc type efficient crushing device comprises a base, a crushing box, a fixed grinding disc, a rotary grinding disc, fine crushing rollers, a driving motor and a material collection tank. The crushing box is arranged on the base. A conveying pipe located inside the crushing box is internally provided with a primary crushing roller. The fine crushing rollers are mounted inside a crushing tank in a rotary manner. A ball screw is arranged between a first sliding rod and a second sliding rod. A horizontal movement plate is mounted on the ball screw in a threaded manner. The material collection tank is fixedly connected to the right side of the horizontal movement plate through bolts. By means of the combined effect of the fixed grinding disc, the rotary grinding disc and the fine crushing rollers, crushing can be conducted twice, and the crushing effect is greatly improved; after crushing is completed, when the medical waste is screened, the crushing tank can swing leftwards and rightwards, and thus the screening speed of the waste inside the crushing tank is increased; in the discharging process, the waste is totally moved out of the crushing box, and compared with common discharging modes, discharging is conducted more thoroughly; and the environmental pollution problem caused due to the fact that waste materials remain inside the crushing box is effectively avoided.

Description

technical field [0001] The invention relates to the medical field, in particular to a grinding disc-type plastic needle tube type medical waste high-efficiency crushing device. Background technique [0002] Medical waste refers to the polluting waste produced by hospitals that have been in contact with patients' blood and flesh. Such as used cotton balls, gauze, tape, waste water, disposable medical needles, postoperative waste products, expired medicines, etc. According to the medical inspection report of the national health department, because medical waste has the characteristics of space pollution, acute infection and latent pollution, its viruses and bacteria are dozens, hundreds or even thousands of times more harmful than ordinary domestic waste. If it is not handled properly, it will cause serious pollution to the environment and may also become the source of epidemics.

If it is not handled properly, it will cause serious pollution to the environment and may also become the source of epidemics

[0003] In medical waste, disposable plastic needle tubes account for a large proportion. Disposable needle tubes are dangerous waste products that can only be destroyed centrally and cannot be recycled. Needle tubes need to be crushed for centralized destruction. When the existing crushing device crushes needle tubes, the crushing process is not thorough and cannot be discharged in a centralized manner, resulting in residual needle tube waste in the crushing box.
