Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1: the utility model provides a take vertical double-shaft mixer of check screen cloth, includes agitator 1, the agitator is including the pan feeding mouth 8 of locating the upper end, establish the discharge gate at the lower extreme and establish the agitating unit at agitator inside, agitating unit includes the (mixing) shaft 4 of vertical setting, 4 upper ends of (mixing) shaft are connected with drive arrangement, the discharge gate top is equipped with check screen cloth 6.

In this embodiment, motor drive is selected for use to drive arrangement, and the agitator includes staving and the bung that links to each other with staving upper end bolt, has seted up the pan feeding mouth on the bung, is equipped with two motors 2 on the bung, and two motors all are connected with the (mixing) shaft alone, and the vertical setting of (mixing) shaft is in the staving.

The middle upper part of the stirring shaft is provided with a first stirring blade 3, the lower part of the stirring shaft is provided with a second stirring blade 5, and the first stirring blade 3 and the second stirring blade 4 are both made of rigid materials, so that the problem that the tail mortar cannot be stirred during stirring is avoided. Wherein, first stirring leaf is one side open-ended square frame structure, and first stirring leaf can be integrated into one piece, and first stirring leaf passes through connecting rod fixed mounting in the well upper portion of (mixing) shaft, can adopt the welded mode to weld first stirring leaf in the one end of connecting rod, and the connecting rod other end welds on the (mixing) shaft. Specifically, the four first stirring blades are symmetrically arranged at the upper part and the middle part of the stirring shaft.

The second stirring blade is a sheet-shaped blade, and the shape of the second stirring blade can be a common shape such as a square shape, a triangular shape or an oval shape or the shape used by the stirring blades in a common stirrer. In this embodiment, the second stirring leaf adopts square thin slice, through connecting rod and (mixing) shaft fixed connection, and fixed connected mode can adopt the welding mode. The second stirring blade is arranged obliquely relative to the bottom of the stirring barrel, wherein the upward surface of the second stirring blade and the bottom of the stirring barrel are arranged at an obtuse angle, specifically 135 degrees.

The two stirring shafts rotate oppositely during working, and the structural form of the stirring shafts can realize multi-dimensional turbulent surge forced circuitous mixing of filling materials, strengthen material diffusion and eliminate forced circuitous stirring in a stirring low-efficiency area; the rigid stirring blade with the inclination angle at the bottom of the stirring shaft can stir and mix the slurry uniformly, and also can roll the slurry, so that the slurry can reciprocate in the space of the barrel body, the blade at the upper part of the stirring shaft can be in contact with the slurry for a longer time in a wider range, and the stirring effect can be further improved.

In this embodiment, still be equipped with check screen cloth 6 between (mixing) shaft bottom and the discharge gate, the shape of check screen cloth is unanimous for circular with the cross-sectional shape of agitator, and the external diameter size of check screen cloth is the same with the internal diameter size of agitator, can install in the agitator seamlessly. The grid mesh can be welded in the stirring barrel or detachably arranged in the stirring barrel; the structure of the detachable installation mode can be that the inner side of the stirring barrel at the position where the grid screen is placed is provided with a bulge, and the grid screen can be placed on the bulge. In addition, be equipped with a plurality of holes diameter and be 2 mm's small opening 7 on the grid screen cloth, small opening 7 is the circumference on the grid screen cloth and distributes, the purpose of this small opening's setting: in the production process, the tailing slurry can be mixed with impurities such as stones and iron wires, and the impurities mixed in the filling slurry such as the stones and the iron wires are left in the stirring barrel through the grid screen, so that the blockage accident caused by the fact that the impurities enter the pipeline through the stirrer is avoided; meanwhile, slurry blocks which are not fully stirred up in the stirring barrel can be broken up again under the combined action of the grid mesh and the rigid stirring blades, so that the filling slurry is fully and uniformly stirred.

And if the check screen cloth adopts the detachable mode to install when in the agitator, the agitator bottom still is equipped with the gag lever post that upwards stretches out, and the gag lever post stretches into in the small opening, carries on spacingly to the check screen cloth, avoids the (mixing) shaft to drive the check screen cloth and rotates together when stirring in the agitator.
