After proper optimization and improvement of the screw press sludge dewatering machine, the machine can be continuously dehydrated, and the front and rear supporting equipment can also be continuously processed, thereby eliminating complicated operation control. The screw press sludge dewatering machine comprises a frame body, a driving device, a screw column, a sieve drum and a spiral blade, wherein the driving device and the screen drum are fixed on the frame body.
In the structural composition of the screw press sludge dewatering machine, the spiral column is located in the sieve drum, and the spiral blade is arranged on the spiral column, and the spiral column is connected to the driving device, the filter drum is provided with a feeding port at one end and the other end is provided with At the feed port, one end of the feed inlet of the sieve drum is lower than one end of the discharge port. It is preferable to tilt the sieve drum by 5-10°, which is advantageous for preventing water from flowing into the concentrated sludge under the action of gravity, thereby increasing the dehydration rate.
In order to further increase the dewatering rate of the screw press sludge dewatering machine, some effective methods can be used:
1. The inner diameter of the sieve drum from one end of the feed port to the end of the discharge port is gradually reduced;
2. The spiral distance between the spiral blades is gradually reduced from one end of the feed port to one end of the discharge port;
3. The diameter of the spiral column gradually increases from one end of the feed port to one end of the discharge port. These three methods can be used alone or in combination with each other.http://www.hy-sewagetreatment.com/
