Description

Technical Field

[0001] The invention belongs to the technical field of material supply and removal, and in particular relates to a special material supply and removal device for a cleaning process. Background Art

[0002] In a special factory, as the operation time increases, special cleaning media needs to be introduced into the process unit, and then the cleaning media and other products in the unit need to be recovered. Therefore, when cleaning the unit, a set of supply and removal devices is required to supply cleaning media and recover cleaning media and products.

[0003] The cleaning medium has a significantly lower saturated vapor pressure than other products, and the utilization rate of the cleaning medium in the unit is generally less than 20%. Therefore, the recovery device is required to separate the cleaning medium from other products as much as possible to facilitate the reuse of the cleaning medium.

[0004] The cleaning process is as follows:

[0005] 1. Use cleaning media to passivate the cleaning device;

[0006] 2. Supply cleaning medium to the unit to be cleaned through the cleaning feeding device, and control the feeding flow rate 1;

[0007] 3. Supply cleaning medium to the unit to be cleaned through the cleaning feeding device and control the feeding flow rate 2;

[0008] 4. Control the pressure of the cleaning unit through the cleaning and material taking device, and recover the cleaning medium and products in the cleaning unit into the container;

[0009] 5. Due to some special reasons, the container in front of the vacuum pump of the material taking device cannot be disassembled, but after cleaning, the material in the container must be poured out.

[0010] 6. In an emergency, various materials in the cleaning unit can be quickly taken out through the material taking device.

[0015] 4. With emergency unloading function;

[0016] 5. The feeding device can be used to passivate and evacuate the material taking device.

[0017] And according to management requirements, no materials can be left in all on-site containers after cleaning, that is, all containers should remain empty.
