[0014] Furthermore, the jacket, collection tank, and top cover are all made of stainless steel.

[0015] The working principle of this technical solution is as follows:

[0016] When collecting waste liquid, first assemble the device in a clean area (temperature sensors and main wheels are not required). Then, push the device to the collection area. Install a sterilized hose at the inlet, connecting the other end of the hose to the container to be collected. Turn on the negative pressure pump to collect the waste liquid into the waste collection chamber. The level sensor monitors the level in the waste collection chamber; when it exceeds a certain value, the negative pressure pump is turned off. Next, immerse the hose in the chemical treatment agent, turn on the negative pressure pump, and add the chemical treatment agent into the waste collection chamber. Then, start the drive unit, which rotates the stirring assembly to agitate the waste liquid in the waste collection chamber. The pH value of the waste liquid is monitored in real time using a pH sensor. Based on the pH value, select the type of chemical treatment agent to add until the pH value meets the discharge requirements. Then, remove the hose, seal the inlet, and move the device out of the clean area from the unloading room. Install the main wheels in the buffer room for support and movement. Push the device to the waste liquid collection tank, then open the first valve to drain the waste liquid from the waste collection chamber. After the waste liquid is drained, the device needs to be cleaned inside and out. Disassemble components that cannot be sterilized at high temperatures, such as the main wheel, pH sensor, level sensor, and drive components. Push other components into the sterilization cabinet for sterilization. After sterilization, remove and reassemble them in the clean area for later use. Disinfect the pH sensor and level sensor by soaking them in 75% ethanol disinfectant before moving them to the clean area.

[0017] When collecting solid waste, first assemble the device in a clean area (pH sensor, level sensor, stirring assembly, and main wheel are not required). Then, push the device to the collection area, remove the top cover, and load the solid waste into the waste collection chamber. Inject purified water into the inactivation chamber, and then turn on the heating equipment to heat the collection tank. The temperature sensor monitors the temperature inside the collection tank in real time. Maintain pressure in the inner cavity of the collection tank to achieve sterilization at 121°C for 30 minutes. After sterilization, move the device out of the clean area from the unloading room, install the main wheel in the buffer room for support and movement, and push the device to the waste collection position. Open the second valve on the second drain pipe to drain the purified water from the inactivation chamber. Then, open the top cover and dump the solid waste. After dumping the solid waste, clean the inside and outside of the device. Disassemble components that cannot be sterilized at high temperatures, such as the main wheel and temperature sensor. Push the other components into the sterilization cabinet for sterilization. After sterilization, remove and reassemble the device in the clean area for later use. Temperature sensors are disinfected by soaking in 75% ethanol solution before being moved into a clean area.

[0018] The beneficial effects of this technical solution are as follows:

[0019] ①In this technical solution, waste liquid can be introduced into the waste collection chamber through a hose, and solid waste can be opened and put into the waste collection chamber, making collection relatively convenient.

[0020] ② By setting up a mobile wheel set, no manual lifting is required during transportation, which can reduce the demand for manpower; it also avoids the risk of falling during transportation caused by using garbage bags, glass bottles or plastic bottles to collect waste, as well as the risk of glass bottles breaking.

[0021] ③ By setting up a top cover, this technical solution can prevent liquid splashing, thereby protecting operators and preventing contamination of the clean area.

[0022] ④ In this technical solution, to facilitate waste liquid collection and prevent waste liquid from backflowing into the tank, a negative pressure pump is added to the top cover to achieve the purpose of "sucking" the waste liquid.

[0023] ⑤ In this technical solution, the chemical treatment agent is introduced through a hose, and then the pH value is detected by a pH testing device to determine whether the pH value of the waste liquid meets the discharge requirements.

[0024] ⑤ In this technical solution, pure water is added to the inactivation chamber and then the heating equipment is started to heat it, which can sterilize solid waste.

[0025] ⑥ In this technical solution, to avoid contamination of the clean area by the moving wheel assembly, a main wheel and a secondary wheel are designed. The secondary wheel is used inside the clean area, and the main wheel is used outside the clean area. The secondary wheel is sterilizable, the main wheel is detachable, and switching between the main wheel and the secondary wheel is convenient. Attached Figure Description
