Description

Technical Field

[0001] The utility model relates to the technical field of medical waste tailings treatment, in particular to a medical waste disinfection tailings forming device. Background Art

[0002] Medical waste has four characteristics: infectious, pathological, damaging and chemical. It is extremely harmful to the environment and human body. If it is not handled properly, the negative impact will be more serious. Incineration and chemical disinfection are common treatment methods for medical waste. The essence of chemical disinfection is to mix the crushed medical waste with a certain concentration of disinfectant (sodium hypochlorite, peracetic acid, glutaraldehyde, ozone, etc.), and ensure that it has sufficient contact area and time with the disinfectant. Organic matter is decomposed and microorganisms are killed during the disinfection process. The maximum contact between the disinfectant and the medical waste is the premise for ensuring the treatment effect. By using shear-type crushing equipment to increase the degree of crushing and ensure that the disinfectant can penetrate it. The tailings after chemical disinfection need to be pressed and formed before recycling, incineration or burial. Therefore, pressing equipment is often used for processing in the tailings treatment process.

A hopper 2, a screw conveyor 3 and a pressing bin 4 are arranged on the frame. One end of the screw conveyor 3 is connected to the discharge port of the hopper, and the other end is connected to the middle of the pressing bin 4. The screw conveyor can be used to transport the tailings in the hopper to the pressing bin to realize the discharge process.

[0021] A pressing plate assembly 5 is vertically slidably disposed in the pressing bin 4, and the pressing plate assembly 5 is connected to an exhaust pipe 6 and an air intake pipe 7, the exhaust pipe 6 is connected to a filter box 22 disposed outside the pressing bin 4, and the air intake pipe 7 is connected to the outside of the pressing bin 4. A pushing assembly 8 is disposed at the lower part of the pressing bin 4, and a bin door 9 corresponding to the pushing assembly 8 is disposed on the pressing bin 4. The pressing plate assembly can press and shape the tailings transported to the pressing bin, and push the tailings out of the pressing bin through the bin door by the pushing assembly, thereby realizing a continuous pressing process.

[0022] When this embodiment is used, the tailings to be processed are first added into the hopper, the pressing plate assembly is located at the upper end of the pressing bin, and the screw conveyor is used to quantitatively convey the tailings in the hopper into the space between the pressing plate assembly and the bottom of the pressing bin. The pressing plate assembly is then pressed downward to compact the tailings to be compacted and formed. The dust gas generated during the pressing process is squeezed into the filter box through the exhaust pipe connected to the pressing plate assembly, and the filter box filters the dust in the dust gas. After maintaining the pressing force of the pressing plate assembly for a period of time, the pressing plate assembly moves upward and resets. During this process, air is introduced into the pressing bin body below the pressing plate assembly through the air intake pipe to maintain air pressure balance. The device has a simple structure and strong practicality. The dust gas emission treatment method generated during the pressing process is simple and reasonable, which reduces the treatment cost.

[0023] Embodiment 2, a medical waste disinfection tailings forming device, based on embodiment 1, a feeding port is provided on the top of the hopper 2, and a bin cover 10 is covered on the feeding port. In this embodiment, an electric stirring paddle 11 is provided in the hopper, and the electric stirring paddle can stir the tailings evenly, and at the same time, it is conducive to uniformly discharge the material to the discharge port below, and the bin cover is provided to facilitate the addition of new tailings to be processed, and at the same time, the dust generated by the tailings is prevented from leaking when the cover is closed.
