According to the production process, the emulsified modified bitumen plants can be divided into three types: intermittent emulsified modified bitumen equipment operation, semi-continuous emulsified modified bitumen plant operation, and continuous emulsified modified bitumen equipment operation. During the production of the emulsified modified bitumen equipments, demulsifier, acid, water, and latex modified materials are mixed in the soap mixing tank, and then pumped to the colloid mill with bitumen. After a tank of soap is used up, it is replenished with soap, and then the production of the next tank is completed.

The emulsified modified bitumen plant mentioned here includes a hot water pump and a circulating pump. This type of centrifugal water pump generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. Note that it is the sewage outlet at the bottom of the emulsified modified bitumen equipment pump. The water in the water tank is discharged through the filter valve. Some emulsified modified bitumen equipment does not have a filter valve to save equipment costs, so it can only be emptied by loosening the flange anchor bolts at the bottom. There are basically two types of emulsified bitumen plants moisturizing pumps on the market, gear pumps or centrifugal pumps. Gear pumps can only discharge the liquid in the pump through the connecting flange of the pipeline. Centrifugal pumps treat sewage through their own sewage outlets.
When used in the production of emulsified bitumen equipment, according to different modification technologies, the latex pipeline can be connected before the colloid mill or after the colloid mill, or there is no latex pipeline, but the required amount of latex is manually added to the soap tank.
Emulsified bitumen equipment generally uses a cone bottom. However, in order to better process the emulsified bitumen equipments coefficient, the inlet and outlet are usually not placed at the bottom. The moisturizing emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid needs to be discharged through the filter valve at the bottom. Both hot and cold substances in the heat exchanger of the emulsified bitumen equipment need to be discharged.
There will be residual emulsion or water in the colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the emulsified modified bitumen equipments, it will cause the frostbite emulsified modified bitumen plants accident. The residue in the colloid mill can be treated by loosening the finished product pipeline connection bolts. The valve body of many emulsified modified bitumen equipment adopts pneumatic type, and there will be a pump component. The water content in the air will become water stored in the tank after expansion. This part of water should be released in winter.
When draining water or moisturizing emulsion pipeline of the emulsified modified bitumen plant, the ball valve should be in the open state. If there is water in the emulsified modified bitumen equipment during operation or the vacuum pump is caused by the valve being closed, the liquid in the pump and pipeline is not discharged, which will cause the frostbite emulsified modified bitumen equipment accident. The cooling circulating water of the colloid mill, many colloid mills use mechanical seals, which will use cooling circulating water. This part of cooling circulating water should be released. Other areas where water may exist. The high-temperature heat transfer oil pipeline of the emulsified modified bitumen plant is not easy to condense in winter and does not need to be emptied. The emulsified modified bitumen plants will condense in winter, but the volume is not easy to increase during the condensation process and does not need to be emptied.
