Problems solved by technology

[0002] Medical waste pollutes the atmosphere, groundwater, surface water, and soil. The open-air stacking of waste causes the release of a large amount of harmful gases such as ammonia and sulfide, which seriously pollutes the atmosphere. PCBs and dioxins emitted by the waste decomposition Ying et al. are all carcinogens. The pathogens, heavy metals, and organic pollutants carried by medical waste are treated by rainwater and leachate produced by biological hydrolysis, which can cause serious pollution to surface water and groundwater. Under the action of solvent scouring, it enters the soil, resulting in the accumulation and pollution of heavy metals in the soil. Improper treatment of medical waste can also cause secondary pollution to the environment.
[0003] Medical waste contains a large number of bacteria, viruses, and chemicals. The existing treatment of medical waste usually uses the incineration method to treat medical waste. However, a large amount of carcinogens such as "dioxin" will be produced during the incineration process, which will have a negative impact on the environment. Serious impact, based on this, we propose a medical waste crushing device

Embodiment 1

[0026] see Figure 1-5 , a medical waste crushing device, comprising a crushing box 1, a feed hopper 2 fixedly installed on the top of the crushing box 1, a flip cover 3 rotatably mounted on the top of the feeding port, and a sterilization and disinfection device, the crushing box 1 is A crushing device is provided, and the crushing device includes a crushing motor 4 and a first motor support 5 for fixedly installing the crushing motor 4, and the first motor support 5 is fixedly mounted on the crushing box 1, and the crushing The first driving shaft 6 is fixedly installed on the crushing motor 4, and the first driving shaft 6 is rotatably mounted on the crushing box 1, and the first driving shaft 6 inside the crushing box 1 is fixedly installed with crushing teeth. The driving roller 8 of 21, the first driving gear 7 is fixedly installed on the first driving shaft 6 outside the crushing box 1, and the crushing box 1 is provided with several rollers located on both sides of the...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that: the side wall of the crushing box 1 is provided with a discharge port 22, and the crushing box 1 is provided with an output device, and the specific structure of the output device is not added. Limitation, in this embodiment, preferably, the output device includes an output motor 23 fixedly installed on the outer wall of the crushing box 1, an output shaft 24 is fixedly installed on the output motor 23, and the output shaft 24 is rotatably installed on the crushing box 1. On the box body 1, the output shaft 24 is provided with a delivery screw blade 25; by setting the output motor 23 and the delivery screw blade 25, the delivery motor 23 rotates and drives the output shaft 24 to rotate, thereby driving the delivery screw on the output shaft 24 The blades 25 rotate, so that the sterilized broken medical waste is effectively cleaned out from the discharge port 22 on the broken box body 1 .

Abstract

The invention discloses a medical waste crushing device. The medical waste crushing device comprises a crushing box body and a sterilization and disinfection device, wherein the crushing box body is provided with a crushing unit, the crushing unit comprises a crushing motor, a first driving shaft is fixedly installed on the crushing motor, a driving crushing roller is fixedly installed on the first driving shaft, a first driving gear is fixedly installed on the first driving shaft, the crushing box body is provided with first driven shafts, and a driven crushing roller is fixedly installed oneach first driven shaft. By arranging the crushing unit, the crushing motor rotates to drive the first driving gear and the driving crushing roller to rotate, through the gear pair transmission principle, crushing teeth on the driving crushing roller and the driven crushing rollers crush medical waste, the crushing treatment of the medical waste is realized, then the crushed medical waste is sterilized and disinfected by the sterilization and disinfection device, and thus the treatment of the medical waste is completed and meanwhile the environment can be protected.

Description

technical field [0001] The invention relates to the field of medical waste, in particular to a medical waste crushing device. Background technique [0002] Medical waste pollutes the atmosphere, groundwater, surface water, and soil. The open-air stacking of waste causes the release of a large amount of harmful gases such as ammonia and sulfide, which seriously pollutes the atmosphere. PCBs and dioxins emitted by the waste decomposition Ying et al. are all carcinogens. The pathogens, heavy metals, and organic pollutants carried by medical waste are treated by rainwater and leachate produced by biological hydrolysis, which can cause serious pollution to surface water and groundwater. It enters the soil under the action of solvent scouring, resulting in the accumulation and pollution of heavy metals in the soil. Improper treatment of medical waste can also cause secondary pollution to the environment. [0003] Medical waste contains a large number of bacteria, viruses, and che...
