Preferably, the convex rib is located the extension of the edge of the back side of the bottom surface of the material raising blade 10, and the material scraping effect on the bottom of the stirring bin 1 is better.
Referring to fig. 6, the shearing blade 20 includes a shaft hole 21 and a plurality of straight blade portions 22 fixedly disposed on the shaft hole, the shaft hole 21 is also provided with a key slot, one side of each straight blade portion close to the lifting blade 10 is a plane, and the material facing side far away from the lifting blade 10 is inclined upward gradually from front to back to form a single-edge cutting edge 22 a. Compare the blade 10 of raising the material, the more main effect of shearing blade 20 is for cuting, consequently, shear blade 20 adopts the straight blade that has the blade, adopts the unilateral blade of upside (keeping away from the blade 10 side of raising the material), avoids the blade inclined plane of downside to push down mixed sizing material on the one hand, and on the other hand, the inclined plane of the blade of upside also can play certain raising the material effect to promote the mixture of mixed sizing material, for example with the shearing blade 20 shearing collision of more upside. More preferably, if there are a plurality of shear blades 20, the cutting edge inclination of the shear blades 20 from bottom to top may be gradually decreased, so as to gradually decrease the material raising effect.
As shown in fig. 7, the pressing blade 30 includes a shaft hole portion 31 and an inclined blade portion 32 fixedly disposed on the shaft hole portion 31, the shaft hole portion 31 is also provided with a key groove, the inclined blade portion 32 gradually extends radially outward and axially upward from the shaft hole portion, and the upward extending angle tends to the angle of the mixed glue material, so as to exert a certain pressing effect on the lifted material, thereby promoting the mixed glue material to fall rapidly or even at an accelerated speed, avoiding the mixed glue material from rising to the top and even adhering to the silo cover, thereby increasing the circulation speed and increasing the heating rate; the end part of the material pressing blade 30 extending upwards tends to the bin cover, and mixed sizing materials adhered to the bin cover can be cleaned to prevent the mixed sizing materials from gathering, so that all the mixed sizing materials are uniformly heated, and the quality stability is improved. The blade 30 may not have a cutting edge due to its weak shearing function, and may have a smaller cutting edge for improving the cleaning effect.
The fourth embodiment:
in the fourth embodiment, different from the third embodiment, in this embodiment, the bin body and the stirring shaft 2 are horizontally arranged, and the winnowing blade 10 is arranged on the stirring shaft 2 at a position close to the first end of the bin body; the shearing blade 20 is arranged on the stirring shaft 2 at the middle part of the bin body. Likewise, the lifting blade 10 lifts the mixed gum toward the shearing blade 20 to be sheared, collided and rubbed with the shearing blade 20, thereby heating the mixed gum. Compared with the vertical arrangement, on one hand, due to the horizontal arrangement, the mixed sizing material does not need to overcome the gravity to do work in the lifting process, and the material lifting blades 10 can lift the mixed sizing material more easily, so that the power consumption can be reduced; on the other hand, due to the action of gravity, the mixed rubber is gathered at the lower side of the bin body, so that the shearing blades 20 can be fully contacted with the mixed rubber at each time, and the conversion efficiency is improved.
Preferably, in order to avoid the mixed sizing material to one end gathering, stirring vane still includes reverse material raising blade 10, reverse material raising blade 10 sets up the position that is located storehouse body second end on (mixing) shaft 2, and the material raising direction of reverse material raising blade 10 is opposite with the material raising direction of material raising blade 10, also promptly the material raising blade 10 at both ends all will mix the sizing material and raise to middle shearing blade 20 department, thereby form axial and circumferential mixing motion, thereby make mixed sizing material misce bene, and the intensification is also even.
Fifth embodiment:
different from the third embodiment and the fourth embodiment, in the fifth embodiment, the bin body and the stirring shaft 2 are obliquely arranged, so that on one hand, in the process of lifting and mixing the rubber material by the material lifting blades 10, the work done against gravity is reduced, and the power requirement can be reduced; on the other hand, similar to the fourth embodiment, the mixed rubber is gathered at the lower side of the bin body under the action of gravity, so that the shearing blades 20 can be fully contacted with the mixed rubber each time, and the conversion efficiency is improved. The working principle of the fifth embodiment can refer to the third and fourth embodiments, and is not described in detail.
In summary, the stirring and heating main machine of the invention improves the existing stirring and mixing device, and the material lifting blades 10 and the shearing blades 20 are arranged in the stirring bin 1 in a matching manner, so that the material lifting blades 10 push the mixed rubber material to move in a friction manner with the bin body and lift the mixed rubber material, and the shearing blades 20 shear and collide the lifted mixed rubber material, thereby converting mechanical energy into internal energy, rapidly heating the mixed rubber material and reaching the temperature required by desulfurization. Compared with the process mode of electric heating in the prior art, on one hand, the electric heating equipment can be eliminated, and the equipment cost is reduced; on the other hand, the mode of generating heat by shearing friction of mechanical energy is adopted, so that the overall energy conversion efficiency can be improved, and the energy consumption of the whole equipment is effectively reduced.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, extension, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
