Reasons and solutions for the mud not being dry when the snail stacker is discharged

Reasons:

1. Flocculation problem. Due to the snail stacker's particular operating principle, the sewage treated by the snail stacker must be treated with drugs in the early stages. After the sewage is flocculated and precipitated, it is pumped into the equipment for dehydration. The compatibility of the agent and the sewage, the proportion of the agent added, the solubility of the agent, etc. will affect the size of the flocs in the sewage.

If the flocs are too small to meet the feeding requirements between the spiral sheets, the mud will not be pressed dry; if the flocs are too large, the flocs will restrict more water and reduce the mud cake degree.

2. The equipment is not debugged in place. In terms of debugging: first, the flocculation effect of the sewage should be debugged, second, the speed frequency of the main shaft should be adjusted, and third, the gap size of the back pressure plate should be adjusted to follow the sewage flow rate at the mud inlet. Professional masters will adjust the sewage feed flow rate and the gap size of the back pressure plate according to the actual conditions such as the sewage's characteristics and the flocs' size.

Solution:

1. The agent debugging is very important. First, the appropriate agent should be matched according to the characteristics of the sewage treatment, and then the proportion of agent addition should be adjusted according to the speed and size of the flocculation alum flocs so that the sewage can reach a good flocculation state after entering the reaction tank.

2. In addition to the debugging of the agent, the adjustment of the back pressure plate is also very important for the spiral stacking machine. Therefore, after purchasing the spiral stacking machine, it is best to find a professional technician to adjust it to achieve a better treatment effect.
