It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] The following will describe in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0027] Please refer to Figures 1 to 5 , a rotary furnace body for a kiln electric furnace provided by an embodiment of the present utility model, the rotary furnace body for the kiln electric furnace includes: a bottom plate 1, a support plate 5 is movably connected to the top of the bottom plate 1, a rotary boiler body 2 is movably connected to the top of the support plate 5 and the bottom plate 1, a heat preservation layer 21 is arranged outside the rotary boiler body 2, a coil 22 is sleeved outside the heat preservation layer 21, and a feeding assembly 3 is arranged on one side of the rotary boiler body 2 close to the support plate 5.

[0028] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the feeding assembly 3 includes a feeding cylinder 31, the end of the feeding cylinder 31 abuts against and is rotatably connected to the inner wall of one end of the rotary boiler body 2, the feeding cylinder 31 is erected on the support plate 5, a feeding hopper 312 is arranged above the inside of the feeding cylinder 31 in a communicating manner, a spiral conveyor paddle 311 is inserted into the inside of the feeding cylinder 31 in a rotatable connection, and the shaft end of the spiral conveyor paddle 311 away from the rotary boiler body 2 extends to the outside of the feeding cylinder 31.

[0029] It should be noted that: through the setting of the feeding assembly 3, during use, by driving the rotation of the spiral conveyor paddle 311 in the feeding assembly 3 through the drive shaft 71, the raw materials in the feeding hopper 312 can be evenly conveyed into the rotary boiler body 2, without the need for manual feeding by staff, which can not only reduce the workload of the staff, but also improve the uniformity of the feeding distribution, and further make the materials heat more evenly inside the rotary boiler body 2.

[0030] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 5 , a linkage rod 4 is inserted into the rotary boiler body 2 in a rotatable connection, annularly distributed scraping plates 41 are arranged outside the linkage rod 4, one end of the linkage rod 4 close to the support plate 5 extends to the outside of the rotary boiler body 2, the outer wall of the scraping plate 41 abuts against and is slidably connected to the inner wall of the rotary boiler body 2, a support piece 44 is arranged on the top of the support plate 5, a rotating shaft 441 is rotatably connected to the support piece 44, a transmission chain 45 is arranged in a transmission connection between the rotating shaft 441 and the drive shaft 71, a driving gear 43 is arranged on the outer wall of the rotating shaft 441, a driven gear 42 is arranged in an engagement manner outside the driving gear 43, and the driven gear 42 is arranged on one end of the linkage rod 4 located outside the rotary boiler body 2.

[0031] It should be noted that: through the setting of the transmission chain 45, during the rotation of the drive shaft 71, the rotating shaft 441 can be driven to rotate synchronously through the transmission chain 45. At this time, the rotating direction of the shaft rod is the same as that of the drive shaft 71. During this process, the drive gear 43 on the rotating shaft 441 can drive the linkage rod 4 to rotate through the meshing with the driven gear 42. And through the meshing between the two gears, the rotating direction of the linkage rod 4 is opposite to that of the rotating boiler body 2 at this time. Furthermore, the scraper 41 on the outer wall of the linkage rod 4 can be driven to scrape and stir-fry the materials inside the rotating boiler body 2. Therefore, the materials can be heated more evenly inside the rotating boiler body 2, and the uniformity of material firing can be improved.

[0032] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , on one side at the bottom of the support plate 5, a cylinder 51 is installed between the support plate 5 and the bottom plate 1 through a rotating frame. On the other side at the bottom of the support plate 5, a telescopic rod 52 is installed between the support plate 5 and the bottom plate 1 through a rotating frame. A fixed support bar 53 is provided at the top of the support plate 5, and the inner wall of the fixed support bar 53 is rotatably connected to the outer wall of the rotating boiler body 2. On one side of the top of the bottom plate 1 away from the support plate 5, a support frame 6 is provided. A movable support bar 61 is rotatably installed on the top of the support frame 6, and the inner wall of the movable support bar 61 is rotatably connected to the outer wall of the rotating boiler body 2. And the end of the linkage rod 4 is connected to the outer wall of the movable support bar 61 through an adapter frame.

[0033] It should be noted that: during the use process, when the firing of the materials is completed, the cylinder 51 can be controlled to extend. The working cylinder 51 can then lift the support plate 5. At this time, the support plate 5 under the lifting force can lift the rotating boiler body 2 through the fixed support bar 53. Furthermore, the rotating boiler body 2 can rotate with the connection part between the movable support bar 61 and the support frame 6 as the node. Thus, the adjustment of the tilt angle of the rotating boiler body 2 can be completed. Therefore, through the rotation of the rotating boiler body 2, the internally fired materials can be evenly moved outwards, realizing the discharging of the materials;

[0034] At the same time, through the setting of the telescopic rod 52, when the tilt angle of the rotating boiler body 2 is adjusted, the telescopic rod 52 can expand and contract synchronously. After the adjustment of the angle of the rotating boiler body 2 is completed, the telescopic rod 52 can improve the support strength of the cylinder 51 in the horizontal direction, and further improve the stability of the later work of this device.

[0035] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 4A driving motor 7 is provided on the top of the support plate 5, and a driving shaft 71 is provided at the output end of the driving motor 7. The end of the driving shaft 71 is rotatably connected to the outer wall of the fixed support bar 53, and the outer wall of the driving shaft 71 is connected to the rotating boiler body 2 through a driving chain 72.

[0036] It should be noted that by arranging a drive chain 72, a transmission chain 45 and a belt 34 outside the drive shaft 71, when the drive shaft 71 drives the drive shaft 71 to rotate later, the rotating boiler body 2, the linkage rod 4 and the loading assembly 3 can be driven synchronously without setting up multiple power sources.

[0037] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 A fixing frame 32 is mounted on the top of the support plate 5, a rotating rod 321 rotatably connected is inserted inside the fixing frame 32, sliding sheets 322 are sleeved on both sides of the outer wall of the rotating rod 321 through threaded structures with opposite thread directions, the inner wall of the sliding sheet 322 is slidably connected to the outer wall of the support rod in the fixing frame 32, the outer wall of the sliding sheet 322 is provided with a rotatably connected convex rod 323, an extrusion wheel 324 is provided on the outer wall of the convex rod 323, a belt 34 is provided on the outside of the extrusion wheel 324, and two symmetrically distributed pulleys 33 are provided on the inner wall of the belt 34, and the two pulleys 33 are respectively arranged on the end rods of the driving shaft 71 and the screw conveying paddle 311 located on the outside.

[0038] The cam 324 is in a state of being moved in a forward direction so as to move the two sliding plates 322 in a forward direction and move the two sliding plates 322 in a forward direction.

[0039] The working principle of the rotary furnace body for kiln electric furnace provided by the utility model is as follows:

[0040] When using the device later, the staff can first electrically connect the electrical components in the device to the external control box, and then add the materials to be fired into the upper hopper 312;

[0041] Then, the coil 22 can be controlled by an external control box to heat the rotating boiler body 2. Then, the control rotating rod 321 can be rotated to drive the sliding piece 322 to move away from each other through the thread structures with opposite thread directions on both sides of the outer wall. At this time, the sliding pieces 322 moving away from each other can drive the pressing wheel 324 to press and tighten the belt 34 through the convex rods 323 on the outer wall, so that the fit between the belt 34 and the pulley 33 can be made closer.

[0042] Therefore, when the driving motor 7 drives the driving shaft 71 to rotate and drives the rotating boiler body 2 to rotate through the driving chain 72, the spiral conveyor paddle 311 can be driven to rotate by the friction between the belt 34 and the pulley 33. The rotating spiral conveyor paddle 311 can evenly convey the materials in the feeding hopper 312 into the rotating boiler body 2.

[0043] Moreover, during the rotation of the driving shaft 71, the rotating shaft 441 can also be driven to rotate through the transmission chain 45. At this time, the driving gear 43 on the rotating shaft 441 can drive the linkage rod 4 to rotate through the meshing with the driven gear 42, and then drive the scraper 41 on the outer wall of the linkage rod 4 to scrape and stir-fry the materials inside the rotating boiler body 2. Therefore, the materials can be heated more evenly inside the rotating boiler body 2, improving the uniformity of material firing.

[0044] After the firing of the materials is completed, the cylinder 51 can be controlled to extend. The working cylinder 51 can lift the support plate 5. At this time, the support plate 5 subjected to the lifting force can lift the rotating boiler body 2 through the fixed support bar 53, so that the rotating boiler body 2 can rotate with the connection part of the movable support bar 61 and the support frame 6 as the node. Thus, the tilt angle adjustment of the rotating boiler body 2 can be completed. Therefore, through the rotation of the rotating boiler body 2, the fired materials inside can be evenly moved outwards to realize the discharging of the materials.

[0045] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0046] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
