Bionic rhizome type stirrer for sludge dewatering treatment system

Technical Field

The invention relates to the field of sludge dewatering treatment, in particular to a bionic rhizome type stirrer for a sludge dewatering treatment system.

Background

Sludge is a necessary product after sewage treatment in sewage treatment plants and sewage stations, secondary pollution is directly brought to water and atmosphere after the sludge which is not treated by very good treatment enters the environment, and serious threat is also formed to ecological environment and human activities, so that the dehydration treatment of the sludge is a key problem. At present, the sludge dewatering treatment is mainly divided into a mechanical dewatering method, a granulating dewatering method and a natural drying method, and the most adopted method is still the mechanical dewatering method; before mechanical dehydration, a flocculating agent needs to be added into the sludge to improve the dehydration performance of the sludge; however, in order to sufficiently improve the dewatering performance of the sludge so as to satisfy the precondition that the mechanical dewatering method can be used, it is necessary to sufficiently mix the sludge with the flocculant. In order to uniformly mix the sludge and the flocculating agent, the invention provides a bionic rhizome type stirrer which can ensure that the sludge and the flocculating agent are contacted more uniformly and stirred more fully.

The invention comprises the following steps:

the invention aims to provide a bionic rhizome type stirrer for a sludge dewatering treatment system, which can realize uniform spraying of flocculating agent in an inner cylinder, and uniformly stir sludge and flocculating agent by passive stirring of a bionic rhizome type stirring group.

A bionic rhizome type stirrer for sludge dewatering treatment comprises a sludge inlet, an upper end cover, an outer cylinder, an inner cylinder gear, a base, a flocculating agent inlet, an inner cylinder, a power output shaft, a power output gear, a bionic rhizome type stirring group and a stepping motor;

the stepping motor provides power and drives the inner cylinder gear through the power output shaft and the power output gear, so that the inner cylinder rotates, and stirring is mainly carried out by means of a bionic rhizome type stirring group rotating along with the inner cylinder.

The bionic rhizome type stirring group consists of 1 main rhizome and 20 primary rhizome groups;

wherein, 5 rows of first-stage rhizome groups are longitudinally distributed on the main rhizome, 4 columns of first-stage rhizome groups are circumferentially distributed, and each first-stage rhizome group can realize the spraying of the flocculating agent and the simultaneous stirring of the flocculating agent and the sludge.

Each primary rhizome group consists of a primary rhizome and 6 secondary rhizomes (203);

wherein, the primary rhizome has the main function of passively stirring the sludge along with the rotation of the inner cylinder;

the main function of the secondary rhizome is to uniformly spray the flocculating agent in the inner cylinder while stirring.

Further preferably, the sludge is directly conveyed into the inner cylinder through a sludge inlet;

further preferably, the flocculation agent enters the main rhizome interior flow passage through the flocculation agent inlet;

further preferably, the inlet to the primary rhizome inner flow passage is through an outlet at a position where the primary rhizome is installed on the primary rhizome;

further preferably, the final flocculant is flowed through the secondary rhizome interior flow passage to uniformly spray the flocculant onto the inner barrel via capillary roots on the secondary rhizome.

The invention has the beneficial effects that:

1. the flocculant is uniformly sprayed on the inner barrel, so that the phenomenon that the sludge at a certain position in the inner barrel is not contacted with the flocculant can not occur.

2. The two actions of flocculating agent spraying and flocculating agent stirring are performed simultaneously, so that the stirring of the sludge and the flocculating agent is more uniform.
