Embodiment 1

[0024] like figure 1In the shown embodiment, a rotor drying device includes a drying main cylinder 7, a frame 1 and a rotor main shaft 10, the drying main cylinder is placed horizontally on the frame, and the frame is placed between the two sides of the drying main cylinder. Bearing seats 4 are provided at the ends respectively for positioning the rotor main shaft. One end of the drying main cylinder is provided with a feed end 7a, and the other end is provided with a discharge end 7b. The drying main cylinder can rotate relative to the feed end and the discharge end, and is positioned on the frame by the support roller 6a. The top of the feed end is provided with a hot flue gas inlet 5, and the top of the discharge end is provided with a wet flue gas outlet 8. The frame is provided with a bearing seat for positioning the rotor main shaft, the main shaft drive motor 2 and the main cylinder drive motor 601 are provided on the frame, and the reducer 3 is also arranged on the fr...

Embodiment 2

[0028] The basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as image 3 , Figure 4 As shown, the frame is provided with a mud-beating motor 21, and the mud-beating motor is located at the end of the rotor main shaft away from the main shaft driving motor. One end of the transmission inner shaft is connected with the output shaft of the mud-beating motor, and the other end is matched with the inner shaft bearing. The rotor main shaft is provided with a plurality of mud-beating devices, including a mud-beating ball 24, a stopper 28, a ball receiving spring 27, a slide rod 25, and a slide hole arranged on the main shaft wall. The ball and the limiting part are respectively connected with the two ends of the slide bar, the ball receiving spring is sleeved on the slide bar and is located between the limit part and the inner wall of the rotor main shaft, the mud ball is in contact with the outer side wall of the rotor ...

Abstract

The invention discloses a rotor drying device. The rotor drying device comprises a transverse drying main barrel, a rack used for positioning the drying main barrel and a rotor main shaft, wherein a feeding end is arranged at one end of the drying main barrel; a discharge end is arranged at the other end of the drying main barrel; the drying main barrel can rotate relative to the feeding end and the discharge end; a hot flue gas inlet is formed in the top of the feeding end; a wet flue gas outlet is formed in the top of the discharge end; the rotor main shaft is positioned in the drying main barrel; a bearing base used for positioning the rotor main shaft is arranged on the rack; a main shaft drive motor capable of driving the rotor main shaft to rotate and a main barrel drive motor capable of driving the drying main barrel to rotate are arranged on the rack; the rotor main shaft and the drying main barrel are reverse in rotary direction; and a plurality of stirring and pushing rods are arranged on the rotor main shaft. The invention aims to provide the rotor drying device which is capable of carrying out drying treatment on sludge with high moisture content, continuous and stable in drying process, high in drying efficiency, high in integral drying uniformity and good in drying effect.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a rotor drying device. Background technique [0002] A large amount of sludge will be produced in the process of sewage treatment, and the treatment method of these sludges is usually incinerated in a furnace, and the hot flue gas discharged after incineration is about 300 to 400 degrees. Since the initial moisture content of the sludge is about 75% to 85%, the water content is too high to be incinerated. Therefore, before the sludge incineration, the sludge needs to be dried first. After the treatment, the moisture content is greatly reduced. , and then the incineration operation can be carried out. Although the current sludge drying treatment methods can achieve a certain degree of dehydration and drying, there are still many deficiencies in terms of drying efficiency, drying degree, and drying uniformity. Contents of the invention [0003] In order to overcome the...
