Description

Sub-elliptical cylindricality mechanical vertical kiln

The utility model relates to a kind of mechanical vertical kiln of calcining usefulness.

The disclosed various mechanical vertical kilns of prior art, its kiln body all is that cylinder forms rotary body shape, under normal conditions, the frictional resistance that material produces in the blanking process is to wait circle by the distribution of radial direction substantially, limit portion material for making clothes is because of being subjected to the effect of kiln wall, resistance increases, and therefore, increases progressively from the center to edge frictional resistance, the blanking state is the trend that there is rolling on the boundary with the center, so cylindrical kiln middle part blanking piece is so that appearance " taking out the heart " phenomenon is the problem of a common existence; Secondly, cylindrical kiln middle part ventilation condition is poor, anaerobic condition often occurs, and the anoxic calcining certainly leads to the low melting point liquid phase again, impels fire in a stove before fuel is added pull and stretch, increases flowing resistance.Apoplexy is not smooth, and wind limit, limit is surplus, and this phenomenon kiln footpath is big more serious more.

In long-term practice, it is found that, the calcining cross section of the production capacity of kiln and kiln is disproportionate, in 3.6 meters scopes of 1.7 meters-Φ of Φ, Φ 2.5-Φ is the high yield area for 3.0 meters, wherein 2.66 meters kiln specific yields of Φ are the highest, are that the boundary is big and little with it, and production capacity is all on a declining curve, illustrate that the path kiln is uneconomical, big footpath kiln is not advanced yet.

The purpose of this utility model provides a kind of mechanical vertical kiln of high yield type, and this kiln operability is good, and manufacturability is stable, energy efficient, production efficiency height.

For achieving the above object, the technical solution adopted in the utility model is: the kiln body adopts the sub-elliptical cylindricality, and material-feeding mechanism adopts dead axle circular guideway displacement unit cloth, and shedding mechanism adopts hydraulic drive rotation pendulum roll structure.

The utility model architectural feature is: sub-elliptical cylindricality kiln body, the contour curve of its cross section are to be made of by arc 2 radiuses, 4 heart circles; The transmission mechanism of material-feeding mechanism is directly installed on the kiln hood and turns round around dead axle, one end and the lift of cable wire join, the other end is by the fixed pulley of kiln hood top, the fixed pulley and the movable pulley of below are connected with the beanstalk of winnowing with a dustpan in (top) kiln hood, what the pulling cable wire can change the beanstalk of winnowing with a dustpan removes the material radius, movable pulley moves along side's mounted thereto curvilinear guide, variable in distance between fixed pulley and the movable pulley can be adjusted the angle of raising of the beanstalk of winnowing with a dustpan, winnow with a dustpan relative motion between beanstalk end opening and kiln face at the uniform velocity for reaching, one damping mechanism is installed on the final drive shaft of transmission mechanism, the damping mechanism bottom beanstalk pull bar of winnowing with a dustpan, the beanstalk pull bar of winnowing with a dustpan links to each other with the beanstalk of winnowing with a dustpan, final drive shaft transmits moment of torsion by bearing and gives the beanstalk pull bar of winnowing with a dustpan, the bullet pin of symmetry is housed in bearing closes, and the bullet pin slides along the inner ring of curve track circle; Shedding mechanism adopts hydraulic drive rotation pendulum roll structure.

The cloth track of the utility model material-feeding mechanism is consistent with kiln type curve.

The utility model can adopt the beanstalk of singly winnowing with a dustpan to remove material, also can adopt two beanstalks of winnowing with a dustpan to remove material, and two when winnowing with a dustpan beanstalk when adopting, assembly pulley doubles.

Because the utility model has adopted sub-elliptical cylindricality kiln body, dead axle circular guideway displacement unit cloth, hydraulic drive autobiography to put the structure of roller discharging, its good operability, process stabilizing, but energy efficient, output can improve 20-30%.

Below in conjunction with accompanying drawing and the concrete example of implementing the utility model is described in further detail.

Sub-elliptical cylindricality kiln body, its minor axis is got 2.8 meters, and major axis is got 4.2 meters, and its structure as shown in Figure 1,1 is material-feeding mechanism among the figure, 2 is the kiln body, and 3 are rotation pendulum roller shedding mechanism, and 4 is flue, 5 is air intake vent, 6 are the grog outlet, and the contour curve of kiln body section connects arc by 2 radiuses, 4 heart circles and constitutes, as shown in Figure 2.

Material-feeding mechanism: sub-elliptical cylindricality mechanical vertical kiln is identical with cylindrical kiln to the requirement of cloth, guarantee that cloth is even, and gyratory directions is adjustable, and the cloth track of different is sub-elliptical cylindricality shaft kiln is kiln shape curve unanimity together.Material-feeding mechanism of the present utility model is shown in Fig. 3-1, transmission mechanism 8 is directly installed on the kiln hood 17 and turns round around dead axle, cable wire 9 one ends are connected with lift 24, the other end is connected by bearing pin 15 with dustpan 10 by fixed pulley 14,13 and movable pulley 11, what pulling cable wire 9 can change dustpan 10 removes the material radius, movable pulley 11 moves along curvilinear guide 12, variable in distance between movable pulley 11 and the fixed pulley 13 can be adjusted the angle of raising of the beanstalk 10 of winnowing with a dustpan, the vector sum of two motions constitutes oval cloth track, and the cloth curve is shown in Fig. 3-2.Winnow with a dustpan relative motion between beanstalk end opening and kiln face at the uniform velocity for reaching, on the final drive shaft 18 of transmission mechanism 8, add a damping mechanism 7, shown in Fig. 4-1, final drive shaft 18 transmits moment of torsion by bearing 23 and gives the beanstalk pull bar 19 of winnowing with a dustpan, close the bullet pin 21 that symmetry is housed on 20 at bearing, bullet pin 21 is done the constant speed revolution on the inner ring of curve track circle 22, the beanstalk connecting rod 19 of winnowing with a dustpan is connected by bearing pin 16 with dustpan 10 among Fig. 3-1, the orbital curve of bullet pin 21 motions is shown in Fig. 4-2, the curvature of curve changes the variation that can cause frictional force, beanstalk 10 change in rotational speed of winnowing with a dustpan on the final beanstalk pull bar 19 of realizing winnowing with a dustpan.When bullet pin 21 is in curve track circle 22 minor axis location, promptly during the point of the A among the figure, the frictional resistance maximum, rotating speed is minimum, be in the major axis position cloth of kiln this moment, when bullet pin 21 is in the major axis position of curve track circle 22, promptly during the point of the B among the figure, the frictional resistance minimum, rotating speed is the highest, at this moment, is in the minor axis location cloth of kiln, like this, circle for every time and alternately change secondary.

Shedding mechanism adopts rotation pendulum roller discharger, and this discharger can keep the discharging of pendulum roller stable, and speed is fast, discaling roll can overturn automatically, its structure as shown in Figure 5, it is in 912320303 the patent specification that present embodiment adopts 7 discaling rolls, this structure to be disclosed in the patent No..

The utility model can be used to calcination of cement clinker, also can be used for nodulizing and the lime that sintered ironmaking uses.
