Description

Technical Field

[0001] The present invention relates to the field of sludge dewatering treatment, and particularly to a root-like stirrer for a sludge dewatering treatment system. Background Art

[0002] Sludge is an inevitable product after sewage treatment in sewage treatment plants and sewage stations. If the sludge that has not been well treated and disposed enters the environment, it will directly cause secondary pollution to water bodies and the atmosphere, and also pose a serious threat to the ecological environment and human activities. Therefore, the dewatering treatment of sludge is a key issue. At present, the sludge dewatering treatment is mainly divided into mechanical dewatering method, granulation dewatering method and natural drying method. The most commonly used method is still the mechanical dewatering method; before mechanical dewatering, a flocculant needs to be added to the sludge to improve the dewatering performance of the sludge; however, if you want to fully improve the dewatering performance of the sludge to meet the prerequisite conditions for using the mechanical dewatering method, the sludge and the flocculant must be fully mixed. In order to achieve uniform mixing between the sludge and the flocculant, the present invention proposes a root-like stirrer that can make the contact between the sludge and the flocculant more uniform and the stirring more sufficient. Summary of the Invention

[0003] The purpose of the present invention is to provide a root-like stirrer for a sludge dewatering treatment system, which can achieve uniform spraying of the flocculant in the inner cylinder, and through the passive stirring of the root-like stirring group, make the sludge and the flocculant evenly stirred.

[0004] A root-like stirrer for sludge dewatering treatment includes a sludge inlet, an upper end cover, an outer cylinder, an inner cylinder gear, a base, a flocculant inlet, an inner cylinder, a power output shaft, a power output gear, a root-like stirring group, and a stepping motor;

[0005] Among them, the stepping motor provides power, drives the inner cylinder gear through the power output shaft and the power output gear, so that the inner cylinder rotates, and the stirring is mainly carried out by the root-like stirring group that rotates with the inner cylinder.

[0006] The root-like stirring group is composed of 1 main root and 20 first-level root groups;

[0007] Among them, 5 rows of first-level root groups are longitudinally distributed on the main root, and 4 columns of first-level root groups are circumferentially distributed. Each first-level root group can achieve the simultaneous spraying of the flocculant and the stirring with the sludge.

[0008] Each first-level root group is composed of one first-level root and six second-level roots (203);

[0009] Among them, the main function of the first-level root is to passively stir the sludge as the inner cylinder rotates;

[0010] The main function of the secondary root is to evenly spray the flocculant in the inner cylinder while stirring.

[0011] Further preferably, the sludge is directly transported into the inner cylinder through the sludge inlet;

[0012] Further preferably, the flocculant enters the internal flow channel of the main root through the flocculant inlet;

[0013] Further preferably, it enters the internal flow channel of the primary root through the outlet at the position where the primary root is installed on the main root;

[0014] Further preferably, finally, the flocculant flows through the internal flow channel of the secondary root, and the flocculant is evenly sprayed in the inner cylinder through the capillary roots on the secondary root.

[0015] Advantages of the present invention:

[0016] 1. The flocculant is evenly sprayed in the inner cylinder, so that there will be no phenomenon that the sludge in a certain place in the inner barrel does not come into contact with the flocculant.

[0017] 2. By simultaneously performing the two actions of flocculant spraying and stirring of sludge and flocculant, the stirring of sludge and flocculant is made more uniform. Description of the drawings

Detailed implementation mode

[0025] The object of the present invention is to provide a root-like stirrer for a sludge dewatering treatment system, which can achieve uniform spraying of the flocculant in the inner cylinder, and through the passive stirring of the root-like stirring group, make the sludge and the flocculant evenly stirred.

[0026] As Figures 1 to 6 shown, a root-like stirrer for sludge dewatering treatment includes a sludge inlet (101), an upper end cover (102), an outer cylinder (103), an inner cylinder gear (104), a base (105), a flocculant inlet (106), an inner cylinder (107), a power output shaft (108), a power output gear (109), a root-like stirring group (110), a stepper motor (111);

[0027] Among them, the stepper motor provides power, drives the inner cylinder gear through the power output shaft and the power output gear, so that the inner cylinder rotates, and the stirring mainly depends on the root-like stirring group that rotates with the inner cylinder.

[0028] The root-like stirring group (110) is composed of 1 main root (201) and 20 first-level root groups (202);

[0029] Among them, 5 rows of first-level root groups (202) are longitudinally distributed on the main root (201), and 4 columns of first-level root groups (202) are circumferentially distributed. Each first-level root group can achieve the simultaneous spraying of the flocculant and its stirring with the sludge.

[0030] Each first-level root group (202) is composed of one first-level root (204) and six second-level roots (203);

[0031] Among them, the main function of the first-level root (204) is to passively stir the sludge as the inner cylinder (107) rotates;

[0032] The main function of the second-level root (203) is to evenly spray the flocculant in the inner cylinder (107) while stirring.

[0033] In order to enable the flocculant to be evenly dispersed into the sludge, in the present invention, the flocculant is dispersed from the internal flow channel (401) of the main root to each first-level root (204), and then dispersed from the internal flow channel (501) of the first-level root to each second-level root (203), and finally dispersed from the internal flow channel (601) of the second-level root to numerous capillary roots (602) and evenly sprayed onto the sludge through the capillary roots (602).

It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes and modifications within the scope of the claims, which do not affect the essence of the present invention. Without conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.
