Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.
As shown in fig. 1 and 2, a rotary kiln body comprises: the furnace comprises a furnace body 1, wherein a plurality of support rods 2 are circumferentially arranged on the inner cavity side walls at two ends of the furnace body 1, one end of each support rod 2 is positioned on the inner cavity side wall of the furnace body 1, the other ends of the support rods 2 point to the axis of the furnace body 1 and intersect at the axis, two intersections in the furnace body 1 are connected through a rod body 3, the rod body 3 and the furnace body 1 are coaxially arranged, a sleeve 4 is arranged on the outer side wall of the rod body 3, a plurality of layers of shifting sheets 5 are arranged on the outer side wall of the sleeve 4 along the length direction, the circumferential direction of each layer of shifting sheet 5 is uniformly arranged on the sleeve 4, a limit rod 6 is also arranged on the inner cavity side wall of the furnace body 1, and the limit rod 6 is positioned on the rotating track path of the shifting sheets 5; furnace body 1 is when rotating, bracing piece 2 with the body of rod 3 homoenergetic with furnace body 1 synchronous rotation, sleeve 4 is but not fixed because the cover is established on the body of rod 3, and plectrum 5 on the sleeve 4 can contact material or gag lever post 6 etc. in the furnace body 1 lead to sleeve 4 with furnace body 1's rotation is asynchronous, forms anomalous stirring.
The bracing piece 2 at the both ends of furnace body 1 has the bracing piece 2 of one end at least to be dismantled, and the one end of every bracing piece 2 at furnace body 1 both ends is in the same place with welded form intersection respectively, and the intersection point just in time is located the axis of furnace body 1, and the bracing piece 2 at furnace body 1 both ends links together through a body of rod 3, and body of rod 3 sets up with furnace body 1 concentric axis, and the both ends of the body of rod 3 are inlayed and are established or are welded the mutual department at bracing piece 2 promptly. Because there is not the gap between bracing piece 2 and the furnace body 1 inner chamber lateral wall, so furnace body 1 can drive the body of rod 3 and rotate when rotating.
A sleeve 4 is established to the cover on the body of rod 3, fixes a plurality of layers of rings on the interior lateral wall of sleeve 4, and circumference is equipped with a plurality of plectrum 5 on every layer of ring (can save the operation of fixing plectrum 5 on sleeve 4 one by one through the indirect fixed plectrum 5 of fixed ring, has reduced the degree of difficulty of preparation). The sum of the length of the poking piece 5, the radius of the sleeve 4 and the radius of the rod body 3 is smaller than the radius of the inner cavity of the furnace body 1, namely, when the sleeve 4 in the furnace body 1 rotates, the poking piece 5 on the sleeve 4 cannot scratch the side wall of the furnace body 1 and only pokes the upper layer area of materials accumulated in the furnace body 1. The orbit of plectrum 5 is fixed, and the welding is equipped with a gag lever post 6 on the lateral wall of furnace body 1, and part gag lever post 6 is located the orbit of plectrum 5, and the collision on certain dynamics takes place with gag lever post 6 in furnace body 1 free rotation's plectrum 5 very probably promptly, because the surface juncture of the subassembly in the furnace body 1 is mostly the cambered surface, so vibrations after the collision can shake off extruded material on sleeve 4 and plectrum 5. In order to ensure that the shifting piece 5 cannot be clamped in the material and the collision with the limiting rod 6 cannot occur, the amount of the material in the furnace body 1 is not more than one third of the amount mentioned in the inner cavity of the furnace body 1, and if necessary, an auxiliary sleeve 4 such as a motor and the like needs to be additionally arranged on the sleeve 4 to rotate on the rod body 3 and form asynchronous rotation with the furnace body 1, so that the collision probability between the limiting rod 6 and the shifting piece 5 is increased.
The furnace body 1 can be obliquely arranged, and the number of the poking sheets 5 on each layer of one side area with relatively high positions in two ends of the furnace body 1 is smaller than that of the poking sheets 5 on each layer of the other side area. I.e. different levels or material densities. In order to enable the sleeve 4 to be slidably rotated on the shaft 3, the inner diameter of the sleeve 4 needs to be about 1-2cm larger than the outer diameter of the shaft 3.
Besides the overall stirring of the middle area of the furnace body 1, a spiral baffle 7 can be arranged on the side wall of the inner cavity of the furnace body 1. The material can move up and down under the influence of the gravity of the material, and can provide thrust in the horizontal direction of the material (particularly, the mechanical analysis of an Archimedes spiral water pump can be referred to) in the rotating process of the baffle 7 arranged in a spiral manner, so that the material can be fully stirred.
The utility model discloses a set up rotatory plectrum 5 and helical baffle 7 etc. in to the inner chamber of furnace body 1, increase the stirring mechanism (the setting of plectrum 5) in the furnace body 1 and give certain random shock (plectrum 5 and gag lever post 6's collision), improved the stirring degree of material in the furnace body 1, shortened the processing time of whole material.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
