[0006] The utility model provides a rotary incinerator, aiming to solve the problem in the background technique that the existing incinerator sets the scraper to be externally inserted through an electric module, which will occupy a certain space by itself and is not convenient for disassembly, assembly and maintenance.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solution: A rotary incinerator, comprising a bracket and a rotary furnace body installed on the bracket and arranged in an inclined manner, and a discharge port arranged at the lower end of the tail end of the rotary furnace body. A stirring mechanism is arranged inside the rotary furnace body;

[0009] In order to be able to stir the materials inside the rotary furnace body, the stirring mechanism includes two inner lining rings that are adapted to the two ends of the rotary furnace body and are symmetrically arranged. Bearings are fixedly installed inside both of the two inner lining rings. Rings are fixedly installed inside both of the two bearings. At least three evenly distributed inclined struts are hinged on the opposite surfaces of the two rings. Main struts are hinged between every two relatively arranged inclined struts on the two rings. Stirring rods are fixedly installed on the inner side walls of the inclined struts and the main struts. When the rotary furnace body rotates to sinter the materials, the materials will be scattered by the stirring rods on the inclined struts and the main struts, thus completing the stirring and accelerating the sintering. When maintenance is required, the two inner lining rings can be pulled outwards towards the outside of the two ends of the rotary furnace body, so that the inner lining rings drive the hinged inclined struts to stretch outwards, so that the angle between the inclined struts and the main struts changes to a horizontal state, so that the whole stirring mechanism can be taken out of the rotary furnace body, which is convenient for its maintenance. During installation, the device is inserted from one end of the rotary furnace body, and then the two inner lining rings are pushed towards each other, so that the two inner lining rings squeeze and push the two inclined struts, so that the hinged main struts arch up and fit the inner wall of the rotary furnace body, completing the installation. Compared with the existing fixed auxiliary stirring blades arranged on the inner wall of the rotary furnace body, it is more convenient and reliable, improves the service life of the device, and is convenient and fast for maintenance.

Two extension rods hinged to the inner lining rings are arranged opposite to each other on the inner side wall of the inner lining rings. The other ends of the two extension rods extend outside the inner lining rings and are arranged towards the outside of the two ends of the rotary furnace body. Fixing pieces facing outwards are fixedly installed at right angles at the ends of the two extension rods located outside the two ends of the rotary furnace body. Installation holes adapted to the flanges at the two ends of the rotary furnace body are opened on the fixing pieces. After the two inner lining rings are installed into the furnace openings of the rotary furnace body, the two extension rods are rotated so that the two extension rods fit the inner wall of the inner lining rings, so that the external fixing pieces fit the flanges at the furnace openings of the rotary furnace body, and are fixed by inserting bolts into the installation holes, which is convenient and fast. When disassembling the stirring mechanism, the two extension rods are rotated and contracted inwards so that the fixing pieces can be withdrawn from the furnace openings of the rotary furnace body to prevent obstruction during use, which is convenient and fast.

The cleaning mechanism includes a scraper fixedly installed on the side of the inclined support rod and the main support rod facing away from the stirring rod, and a motor installed at the furnace mouth at the tail end of the rotary furnace body. The output end of the motor penetrates the furnace cover at the tail end of the rotary furnace body and extends into the rotary furnace body and is connected to the ring through a driving bracket. By driving the driving bracket to rotate through the output end of the motor, the driving bracket drives the ring to rotate, so that the inclined support rod and the main support rod can scrape the inner wall of the rotary furnace body whether it is working or not, thereby cleaning the residual sintered materials and ensuring the heating efficiency of the rotary furnace body.

[0014] Preferably, the driving bracket is a structure with a U-shaped center fixed to the inner wall of the ring at both ends. A cutting groove adapted to the U-shaped center of the driving bracket is provided at the output end of the motor. In order not to affect the opening and closing of the furnace door of the rotary furnace body, the output end of the motor and the driving bracket are movably installed. Through the cooperation of the cutting groove and the driving bracket, the installation is convenient.

[0015] (III) Beneficial effects

[0016] For this incinerator, when maintenance is needed, the two inner lining rings can be pulled outward towards the outer sides of the furnace mouths at both ends of the rotary furnace body, so that the inner lining rings drive the hinged inclined support rods to stretch outward, so that the angle between the inclined support rods and the main support rods changes to a horizontal state, and thus the whole stirring mechanism can be taken out of the rotary furnace body, which is convenient for its maintenance. During installation, the device can be inserted into the rotary furnace body from one furnace mouth at one end, and then the two inner lining rings are pushed towards each other, so that the two inner lining rings squeeze and push the two inclined support rods, so that the hinged main support rod arches and fits with the inner wall of the rotary furnace body to complete the installation. Compared with the existing fixed auxiliary stirring blades arranged on the inner wall of the rotary furnace body, it does not occupy the external space of the rotary furnace body, is more convenient and reliable, improves the service life of the device, and is convenient and fast for maintenance.

[0017] For this incinerator, by driving the driving bracket to rotate through the output end of the motor, the driving bracket drives the ring to rotate, so that the inclined support rod and the main support rod can scrape the inner wall of the rotary furnace body whether it is working or not, thereby cleaning the residual sintered materials and ensuring the heating efficiency of the rotary furnace body.

A stirring mechanism 4 is arranged inside the rotary furnace body 2;

[0027] The stirring mechanism 4 includes two inner lining rings 41 that are adapted to the two ends of the rotary furnace body 2 and are symmetrically arranged. Bearings 42 are fixedly installed inside the two inner lining rings 41. Rings 43 are fixedly installed inside the two bearings 42. At least three evenly distributed inclined support rods 44 are hinged on the opposite surfaces of the two rings 43. Main support rods 45 are hinged between every two relatively arranged inclined support rods 44 on the two rings 43.

When maintenance is required, the two inner lining rings 41 can be pulled outward towards the outer ends of the two furnace mouths of the rotary furnace body 2, so that the inner lining rings 41 drive the hinged inclined support rods 44 to stretch outward, so that the angle between the inclined support rods 44 and the main support rods 45 changes to a horizontal state, so that the stirring mechanism 4 as a whole can be taken out of the rotary furnace body 2, facilitating its maintenance. During installation, the device is inserted from one furnace mouth end of the rotary furnace body 2, and then the two inner lining rings 41 are pushed towards each other, so that the two inner lining rings 41 squeeze and push the two inclined support rods 44, so that the hinged main support rods 45 arch up and fit against the inner wall of the rotary furnace body 2 to complete the installation.
