Description

Funnel-cap type tripper

The utility model belongs to a kind of dumping device that mechanized cement shaft kiln is produced cement.Exactly this device is the double-edged fine-toothed comb of blast cap formula, back and forth rotation, internal force transmission.

In the prior art, that the dumping device of mechanized cement shaft kiln has is tower, disc type, dish is tower, reciprocating type, pendulum roller type is several, and wherein the double-edged fine-toothed comb of first three kind all is that 360 degree circumference rotatablely move; Shuttle double-edged fine-toothed comb is two semicircle grate plates with holes, back and forth rubbing; The double-edged fine-toothed comb and the roller of pendulum roller type are made of one, middle logical water coolant, reciprocally swinging.They all are the external force transmission, and promptly driving torque will borrow basis and kiln room to come balance, therefore basis and kiln room are required than higher, and in little cement was transformed, quality was better, are originally native shaft kiln room to be installed be difficult to utilize, and investment for trnasforming urban land is big, and the cycle is long.In the middle of burning till, a little less than the broken bulk ability of double-edged fine-toothed comb, especially with reciprocating type, pendulum roller type more very, cause the bottom built on stilts sometimes; Central ventilation is poor; The grog lumpiness is bigger, and it is more to take away heat; Electrical control separates up and down, operation inconvenience.Because structural relation, mounting or dismounting are all difficult.

For the old preferably kiln of quality room can be used when transforming, improve firing process, be convenient to mounting or dismounting and operation, ad hocly counted dumping device of the present utility model.

After the scheme implementation of the present utility model, manufacturing cost obviously reduces, and investment for trnasforming urban land can be saved about 200,000 yuan, and the transformation cycle can be carried about the first five months, and central ventilation is good, unit cross-sectional area output height, mounting or dismounting and easy to operate.

For design concept of the present utility model is described visually, ask for an interview:

The transmission of Fig. 1 external force is converted into internal force transmission synoptic diagram

Fig. 2 twin-tub push-and-pull hydraulic schematic diagram

Fig. 3 blast cap formula dumping device synoptic diagram

Design concept of the present utility model is:

One, changes traditional external force transmission into the internal force transmission. As shown in Figure 1, the external force transmission schematic diagram that its left Fig. 1-1 is tower discharge device, by external force moment is passed to a large ratchet or gear wheel (1), make big vertical shaft (2) rotation, drive tower comb (6), by material piece (3) moment is passed to kiln body (4), pass to again kiln room (5), average out with ground then. The moment that kiln room (5) will bear broken grog. Right Fig. 1-2 is the internal force transmission schematic diagram of funnel-cap type tripper, the turning moment of rotating disk (8) by be fixed on two fluid cylinders on the chassis (9) push away or draw produce, as shown in Figure 2, it drives funnel-cap type double-edged fine-toothed comb (7) rotation, by the material piece (3) moment is passed to kiln body (4), again and chassis (9) average out. This moment size and kiln room (5) are irrelevant. So whole kiln body can support with three steel columns (10) that rise from the level ground. Kiln face height can be regulated by the length of three columns. Like this, many quality just can use in old kiln room preferably.

Two, change the discharging double-edged fine-toothed comb into funnel-cap type. As shown in Figure 3, be that body is blast cap (7) with holes, outer surface uniform two the volume loop type claws (12), bulk grog (3) is pushed up broken on the top of double-edged fine-toothed comb (7), and loose to kiln body (4) edge, inside and outside kiln body (4) edge, be provided with two volume taper Jaw plates, inner conical Jaw plate (14) connects together with double-edged fine-toothed comb (7), male-tapered Jaw plate (15) and kiln body (4) connect together, in case the material piece falls between the claw (12), because claw (12) effect of component is downwards pressed to broken mouthful of taper Jaw plate to material, grog moves downward by Gravitative Loads and becomes the external force pressure, thereby realizes the discharging purpose.

Three, from the air of gas blower, tilt to enter the lower central airduct (24) in the conical hopper (27) at a high speed, make its lower end produce a negative pressure, cause air draught (25), the upper end is most of to form apoplexy (11) by central upper portion airduct (19), and small part forms whirlwind (21) by cyclone plate (20), has so both improved central ventilation, make Uniform Ventilation again, favourable heat recuperation.

Four, the dynamic seal of large end face adopts secondary maze formula sealing (28) and pressure reduction sealing to combine between chassis (9) and the rotating disk (8), its principle is with a leather hose (16) chassis (9) inner chamber (18) to be linked to each other with air main (17), if air main (17) wind speed is ω, because little the getting of the interior wind speed of leather hose (16) can be not significant, quote Bernoulli equation, then the air pressure of inner chamber (18) will be all the time than a big dynamic pressure 1/2 ρ ω of air pressure in the conical hopper (27) ²Like this, the dust in the conical hopper just can not be gone to inner chamber (18).Thereby reach sealing purpose.

Five, the grog (23) after the change fragmentation is in case leave the structure that inside and outside bell promptly falls, make the bed of material that the high chance of a pile be arranged, the height of its accumulation is controlled by the material level sensing (22) of design voluntarily, thereby reaches the purpose of refinement grog and reduction grog temperature out.

Six, the dumping device electrical control of prior art all is located under the kiln, separate with the kiln face, and the kiln face will to be adjusted the discharging situation at any time according to the situation of burning till, for this reason, design of the present utility model is unified electric control box up and down, and be located at the kiln face, below grog block, the rotating disk fault can be passed through the message treatment circuit, in time on the controlling box panel of kiln face, reflect, like this, not only can save the operative employee under the original kiln, and easy to use.

Be exactly the utility model most preferred embodiment below:

See Fig. 3, whole machine shaft kiln comprises kiln body (4) blast cap formula dumping device and grog (3) by three φ 325 * 15 steel pipe posts (10) supporting of rising from the level ground, and column (10) is high 4.5 meters, is isosceles triangle and distributes.Blast cap formula double-edged fine-toothed comb body (7) with holes is a steel casting, its outside surface uniform rectangle loop type claw (12), the claw material is attrition resistant casting manganese steel.Blast cap formula thin bamboo strip (7) is to be bolted on the rotating disk (14), rotating disk (14) relies on two fluid cylinders that are fixed on the chassis (9) to push away or draws, produce back and forth rotation, grog after the fragmentation (23) is deposited in the conical hopper (27), the height of piling up is controlled by material level sensing (22), material level sensing (22) is actually a weight, it back and forth rotates with rotating disk (8), run into grog, promptly rotate an angle, by mercuryswitch, send an electric signal, make the following grog handling equipment work of dipleg (26).So the design's grog fine size can save a 17KW formula crusher to the user, directly into mill, its tricks of the trade are to control the height that the interior grog of conical hopper (27) has an accumulation exactly without fragmentation.Major diameter end face dynamic seal between its rotating disk (8) and chassis (9) is to have connected a leather hose (16) between chassis (9) and air main (17), and employing secondary maze formula seals and differential sealing combines, and way solves.Make inner chamber (18) pressure all the time than big in the conical hopper.

Air from gas blower, not directly upwards, but tilt to enter lower central airduct (24) with conical hopper (27) two limit symmetries, make the lower end produce air draught (25), the upper end produces a whirlwind by cyclone plate (20), and apoplexy by central upper portion airduct (19) directly upwards, be the flat board of a circle above the cyclone plate (20), below uniform six guide plates that produce whirlwind, wind blows out along guide plate, just produces rotation.

After grog after the fragmentation and whirlwind, the air draught heat exchange, because fine size, the residence time is long, cooling rapidly, and the grog that comes out can directly be carried with rotary conveyor, produces the scale of 50,000 tons of cement per year, and year economizes on coal can be more than 100 tons.And the prolongation of grog cooling time, its tricks of the trade also are the height of an accumulation, rather than are to reduce output.It is controlled by the time relay by material level sensing (22).Its cooling time can be than long tens times of generalized case.

Its electric control box is placed on the kiln face, and situation under the kiln is blocked as grog, alarm display automatically such as rotating disk fault.
