[0002] When the existing sludge treatment and dewatering device is in use, there are often some problems. For example, most of them only use a simple structure to filter out the water in the sludge and do not have the performance of deep dewatering. Another example is that the filter screen used for water filtration on the equipment is prone to blockage during use, which will also affect the dewatering efficiency and effect of the sludge to a certain extent. For this reason, we propose a deep sludge dewatering device for sludge treatment to solve the problems raised in the above background technique. Content of the Utility Model

The water collection tank is fixedly installed on the right side of the top of the bottom plate. The number of brackets is two and they are symmetrically installed on the front and back sides of the water collection tank. The primary dewatering mechanism is fixedly installed at one end of the two brackets. The secondary dewatering mechanism is fixedly installed on the left side of the top of the bottom plate and is interconnected with the primary dewatering mechanism;

[0005] The primary dewatering mechanism includes a dewatering cylinder. The dewatering cylinder is fixedly installed at one end of the two brackets.

The left side of the bottom of the dewatering cylinder is fixedly connected with a material passing pipe communicated with it. A driving motor is fixedly installed on the left side of the dewatering cylinder. The output shaft of the driving motor penetrates into the dewatering cylinder and extends to the outside of it and is fixedly connected with a driving runner. A stirring blade is fixedly connected to the surface of the output shaft of the driving motor located inside the dewatering cylinder. A main filter screen is fixedly installed in the concave opening at the bottom of the dewatering cylinder. A fixing plate is welded on the left side of the bottom of the dewatering cylinder and at the main filter screen.

One end of the screw rod is fixedly connected with a driven runner. The driven runner and the driving runner are connected by a belt drive. A translation block is threadedly connected to the screw rod along the axial direction. The translation block slides along the axial direction on the surface of the guide rod. A cleaning brush is installed on the upper surface of the translation block.

[0006] Further, the secondary dehydration mechanism includes a compression box and a water storage shell. One end of the material passing pipe is communicated with the compression box.
