Abstract

The invention provides a stirring blade structure of a sludge drier. The stirring blade structure is suitable for a hollow paddle type sludge drier. The stirring blade rotates with a hollow thermal shaft as the axis and also makes reciprocating translation motion along the hollow thermal shaft, and therefore sludge adhering to the thermal contact surface of the hollow thermal shaft can be removed in time; the blade also has torsional vibration function, so that adhesion of sludge on the surface of the blade can be reduced, stirring intensity can be improved, and caking of sludge can be inhibited; the stirring blade structure is driven through circulation of smoke generated from sludge incineration, the utilization efficiency of combustion smoke is improved, driving load of a hollow thermal shaft motor is not increased, the space of a sludge delivery channel is not reduced, and accidental jamming and machine breakdown do not occur easily.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment, in particular to a stirring paddle structure applied to a sludge dryer. Background technique

[0002] Sludge is an important pollution output formed in industrial and agricultural production and urban life. will produce sludge. Sludge contains a large number of harmful microorganisms, heavy metals and organic pollutants. If not properly disposed of, it will have a serious negative impact on the natural environment and people's health.

[0003] Sludge incineration is to make the combustible substances in sludge burn at high temperature and make them oxidatively decompose, so as to achieve the purpose of reducing sludge capacity, killing harmful microorganisms, removing toxicity and making full use of energy. Sludge incineration is a widely used and mature sludge high-temperature treatment technology in foreign countries. It can minimize the volume of sludge, and has the advantages of fa...

Embodiment Construction

[0027] The technical solutions of the present invention will be further specifically described below through examples.

[0028] first preferred embodiment

[0029] The stirring paddle structure provided by the invention is applied to a hollow paddle sludge dryer. Figure 2A-2BA hollow paddle sludge dryer equipped with the stirring paddle structure is shown. The drying machine includes a drive motor 201, a biaxial transmission box 202, a heat exchange chamber 203, a first hollow paddle 204, a second hollow paddle 205, a heat medium delivery pump 206, a heat conduction jacket 207, an air inlet 208, and a steam outlet 209, material inlet 210 and material outlet 211. The drive motor 201 is used to provide driving force for the rotation of the first hollow paddle 204 and the second hollow paddle 205 around its hollow paddle shaft; the double shaft transmission box 202 is connected to the motor shaft of the drive motor 201 and has two torque output shafts, two The two torque outp...
