Description

Technical Field

[0001] This utility model relates to a cell-breaking component for an activated sludge dewatering machine. Background Technology

[0002] The negatively charged functional groups in sludge ionize to produce extracellular polymers (EPS). These substances maintain a stable hydrated colloidal structure, thus hindering the release of water. If the sludge is not destroyed, it is difficult to achieve the desired dewatering effect by directly dewatering it.

[0003] Currently, there is a method of adding chemicals to activated sludge to separate solids and liquids and achieve dewatering. However, after adding chemicals, the dried sludge cannot be reused as fertilizer because the chemical components pollute the soil and groundwater, thus harming the environment.

[0004] How to avoid secondary pollution and achieve effective pretreatment of sludge, thereby improving the pretreatment effect, has become an urgent technical problem to be solved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cell-breaking component for an activated sludge dewatering machine.

[0007] In order to pre-treat the sludge entering the activated sludge dewatering machine, reduce the wear and tear of the dewatering machine, and improve the processing efficiency, a cell-breaking component for the activated sludge dewatering machine is provided. The cell-breaking component includes a straight pipe; a first radial pipe and a second radial pipe are respectively arranged radially on the straight pipe.

[0008] The straight tube, the second radial tube, and the first radial tube form a three-axis system with the X-axis, Y-axis, and Z-axis perpendicular to each other.

[0009] As a further improvement to the above technical solution:

[0027] The spindle has a shoulder that passes through bearing housing A and is axially positioned;

[0028] A crushing disc is provided on both the secondary spindle and the main spindle; a spacer sleeve is provided between adjacent crushing discs.

[0029] The grinding disc has raised sections around its perimeter; a right-angled step is provided on the front of the raised section and has an oblique back side; a raised slice is embedded in the right-angled step.

[0030] The two sides and the top edge of the raised slice extend out of the body of the raised part.

[0031] The raised slices of the sub-spindle and the raised slices of the spindle are arranged alternately.
