Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Such as the following terms "axial," "radial," and the like, to indicate orientation or positional relationship are based solely on the orientation or positional relationship as shown in the drawings and are used solely for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices/components must have a particular orientation or be constructed and operated in a particular orientation and are, therefore, not to be considered limiting of the invention.

It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.

Referring to fig. 1 and 2, a draining roller of a belt type dehydrator, which is installed at a squeezing section of the belt type dehydrator and cooperates with a squeezing filter belt to squeeze out water in sludge, comprises a steel pipe 1, a blocking plate 3 for blocking two ends of the steel pipe, and a roller shaft 2 connected with the blocking plate.

The steel pipe 1 is provided with a plurality of radial diversion holes 11, and the blocking plate 3 is provided with a plurality of axial diversion holes 31. During the operation of the dewatering machine, a large amount of water extruded out flows into the steel pipe from the radial diversion holes with the upper sides contacting with the filter belt by utilizing the draining characteristic of the holes. The water in the steel pipe flows out from the radial diversion holes at the lower side and the axial diversion holes of the blocking plates at the two sides. Therefore, the drainage effect can be increased, and the water content of the sludge is reduced to a certain degree.
