The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Combine a spiral stirring blanking structure for concentrated machine of central drive for concentrated machine of figure, including the awl hole 3 that is located concentrated machine feed opening department to and concentrated machine inside central transmission shaft 1, be equipped with stirring blanking structure on the central transmission shaft 1, stirring blanking structure is located inside the awl hole 3, include: two helical blade 2 of symmetric design, helical blade 2's upper end is connected with central transmission shaft 1 through last connecting piece 4, and helical blade 2's lower extreme is connected with central transmission shaft 1 through connecting piece 5 down, just, the length of going up connecting piece 4 is greater than the length of connecting piece 5 down. The helical blade 2 is of an involute helical structure.
Because the contact area between the blade side surface of the helical blade 2 and the material is larger, the viscous material can be stirred along with the rotation of the helical blade 2,
the cone pit 3 is characterized by large upper part and small lower part, so the material in the cone pit 3 has the characteristics of large upper part and small lower part, the helical blade 2 is made into an involute helical structure according to the characteristics of large upper part and small lower part of the cone pit 3, and the area of the blade surface of the helical blade 2 is larger corresponding to the area of the blade surface of the helical blade 2 aiming at the place with more material, so that the material in the cone pit 3 can be uniformly stirred in the rotating process of the helical blade 2.
And the material at the edge of the conical pit 3 converges towards the center in the stirring process, and meanwhile, due to the characteristic that the helical blades 2 can convey the material, the material converged towards the center can also move downwards, so that the material is promoted to be discharged from the discharging opening.
Because the upper end and the lower extreme of helical blade 2 all are fixed on central transmission shaft 1, so the angular velocity of whole helical blade 2 is the same, but the linear velocity of the leaf sword on the blade is different, and leaf sword linear velocity that the distance is more far away from central transmission shaft 1 is also higher, like this under the condition that there is more material in awl pit 3 upper portion, the linear velocity of leaf sword is also faster, can better cutting material, make the material gum chain that makes difficult to flow cut off, better realization material stirring.
As shown in fig. 3, the upper connecting piece 4 is perpendicular to the lower connecting piece 5, so that the helical blades 2 can be symmetrically arranged, and uniform stirring is ensured.
As shown in fig. 1, the upper connecting member 4 includes an upper connecting rod 6 and an upper sleeve 7, the upper sleeve 7 is welded on the central transmission shaft 1, the upper connecting rod 6 is disposed on both sides of the upper sleeve 7, and the other end of the upper connecting rod 6 is welded to the upper end of the helical blade 2. Go up sleeve pipe 7 and cup joint and carry out the welding after central transmission shaft 1 goes up, can increase the area of contact of sleeve pipe 7 and central transmission shaft 1 like this, go up sleeve pipe 7 rethread connecting rod 6 and be connected with helical blade 2's upper end, at the rotatory in-process of helical blade 2, because the material viscosity is high, so, the resistance that helical blade 2 received is great, on transmitting the resistance to last sleeve pipe 7 through last connecting rod 6 like this, because it cup joints on transmission shaft 1 and welds to go up sleeve pipe 7, so, it can transmit the resistance on transmission shaft 1 completely to go up sleeve pipe 7, reduce the cracked risk of last connecting rod 6.
The lower connecting piece 5 comprises a lower connecting rod 8 and a lower sleeve 9, the lower sleeve 9 is welded on the central transmission shaft 1, the lower connecting rod 8 is arranged on each of two sides of the lower sleeve 9, the other end of the lower connecting rod 8 is welded with the lower end of the helical blade 2, the lower sleeve 9 is sleeved on the transmission shaft 1 and welded, and the lower sleeve 9 can evenly transmit resistance force borne by the lower end of the helical blade 2 to the transmission shaft 1 so as to protect the lower connecting rod 8.
The helical blade 2 of the stirring and blanking structure adopts an involute helical structure, the contact area of the helical surface of the helical blade 2 and the material is large, and the viscous material can be uniformly turned up; in addition, the side edge of the spiral blade 2 can also cut materials, so that the materials which are difficult to flow cut off a colloid chain, and meanwhile, the spiral shape also facilitates the ore pulp with higher viscosity concentration to be smoothly discharged out of a cone pit of the thickener, and the structure can enable the blanking of the thickener to be more uniform.
