Pressure regulation type sludge dehydration device

Abstract

The invention discloses a pressure-regulating sludge dewatering device, which comprises a device body; the device body is mainly composed of an outer shell, an inner shell, a sewage inlet, a drainage pipe and a sludge discharge pipe; the top of the inner shell is fixed A pretreatment shell is connected, the bottom of the pretreatment shell is fixedly connected with a filter plate, the outer shell of the inner shell is covered with an outer shell, the bottom of the filter plate is fixedly connected with an electric lifting device, and the bottom of the electric lifting device is fixedly connected with a piston plate. The bottom surface of the piston plate is pressed against a pressure plate, the bottom of the piston plate is fixedly connected with an installation frame, the installation frame is fixedly connected with a drive motor, the bottom of the drive motor is fixedly connected with a rotating shaft, and a second stirring rod is hinged on both sides of the bottom of the rotating shaft , the bottom of the inner casing is fixedly connected with a mud discharge pipe, and the bottom of the inner casing is fixedly connected with a heating device. The device improves the stirring efficiency of sewage, and the piston plate effectively increases the pressure of sewage in the inner casing, shortening the time required for sewage to filter sludge.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a pressure-regulating sludge dewatering device. Background technique [0002] With the rapid development of my country's economy, the ensuing environmental pollution problems are also quite serious. A large amount of sewage is produced every day. Activated sludge is often used in the process of sewage treatment, but activated sludge needs to be dehydrated after use. To reduce the space occupied by activated sludge. [0003] Sludge dehydration requires the use of a sludge dehydrator, which is used to remove water from the sludge. Existing dehydrators include various sludge dewatering devices such as plate press dehydrators and centrifugal dehydrators. The sludge dewatering devices mainly use Sludge filters water and discharges sludge. [0004] During the use of the existing sludge dewatering device, due to the low stirring efficiency of the sludge, the moisture in the sludge is di...

Problems solved by technology

[0004] During the use of the existing sludge dewatering device, due to the low stirring efficiency of the sludge, the moisture in the sludge is difficult to discharge, resulting in a relatively large moisture content of the sludge, and it is difficult to process and transport the sludge after it is discharged.
