A cylindrical storage tank 5 is arranged on the top surface of the material stirring bar 3, the storage tank 5 is arranged in the middle of the material stirring bar 3, the axis of the storage tank 5 is parallel to the axis of the barrel 1, the cross section of an opening of the storage tank 5 is a minor arc, the material guiding bar 4 comprises a fixing shaft 6 fixed in the storage tank 5, the axis of the fixing shaft 6 is overlapped with the axis of the storage tank 5, a lantern ring 7 is sleeved on the fixing shaft 6 in a rotating manner, a counterweight 8 is fixedly connected to the lower end of the lantern ring 7, the counterweight 8 is always positioned at the lower side of the fixing shaft 6 under the action of self gravity and cannot move along with the material stirring bar 3, the outer surface of the counterweight 8 is a cambered surface attached to the inner side wall of the storage tank 5, no gap exists between the side wall of the counterweight 8 and the side wall of the storage tank 5, manganese salt is prevented from falling between the counterweight 8 and the storage tank, the length of the cambered surface of the counterweight 8 is not less than the length, the counterweight 8 can completely block the outlet of the silo 5.
Further, the cross section of the weight member 8 is fan-shaped.
As shown in fig. 3, the cross section of the weight member 8 is fan-shaped, and both side walls of the weight member are obliquely arranged, so that when the rotary kiln works, the drum body 1 can continuously rotate, the material-making strip 3 is fixed with the drum body 1 and can also rotate along with the drum body, and the weight member 8 is always kept unchanged under the action of the gravity of the weight member 8, so that the weight member 8 and the material-making strip 3 can generate relative displacement.
As shown in fig. 1, when barrel 1 rotates along the arrow direction in the picture, be located the bottommost strip 3 of making a book, the opening of its storage tank 5 is in the open mode, manganese salt not only can get into in the storage tank 5, manganese salt still can pile up on this strip 3 left inclined plane of making a book, along with the rotation of barrel 1, the contained angle of left side inclined plane and vertical face becomes the obtuse angle by the acute angle gradually, manganese salt on the left side inclined plane also can drop under the effect of self gravity, meanwhile, manganese salt on fan-shaped cross section's weight 8 right side also can be pushed out outside storage tank 5 gradually, realize that manganese salt is located left first throwing in barrel 1.
As shown in FIG. 4, as the drum 1 continues to rotate, the strip 3 moves to the uppermost end of the drum 1, and the manganese salt on the left side of the weight member 8 is sealed in the storage tank 5 and does not fall down.
With the continuous rotation of the cylinder body 1, the material-making strips 3 rotate to the right side, at the moment, the opening of the material storage tank 5 is opened again, the manganese salt stored in the material storage tank can drop under the action of the self gravity, and the manganese salt in the cylinder body 1 on the right side is thrown for the second time.
Compare in current rotary kiln, this device can realize the secondary of manganese salt and shed through simple structure on the basis that does not increase extra energy consumption, makes manganese salt can be dried more evenly, fast.
Example 2
As shown in fig. 5 to 7, the present embodiment is different from embodiment 1 in that: the cross section of counterweight 8 is semi-circular, and counterweight 8 is formed by the concatenation of the fan-shaped strip of high density 9 and the fan-shaped strip of low density 10, makes counterweight 8 under self action of gravity, and its plane remains throughout and is the slope setting with vertical plane, need explain that, in this embodiment, counterweight 8's inclination needs to set up according to barrel 1's direction of rotation, and is concrete, and this fan-shaped strip of high density 9 should set up the front side at barrel 1 direction of rotation, and fan-shaped strip of low density 10 should set up the rear side at barrel 1 direction of rotation.
In this embodiment, when the material stirring strip 3 is located at the lowest side of the cylinder 1, the storage tank 5 in the material stirring strip stores manganese salt, and along with the rotation of the cylinder 1, an opening of the storage tank 5 is quickly blocked by the counterweight 8, so that the manganese salt is stored in the storage tank 5, and when the material stirring strip is located at the left side of the cylinder 1, the manganese salt accumulated on the inclined plane of the material stirring strip 3 falls downwards to form primary throwing.
The strip of copying 3 is along with barrel 1 rotates when to the right side, and the opening of its stock chest 5 is opened, and inside manganese salt falls in proper order, forms the secondary and spills, and this embodiment can the manganese salt volume that the greatly increased secondary was spilled, makes the difference between the 1 twice volume of spilling of barrel reduce for manganese salt is by even stoving.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
