Abstract

The invention relates to a granulator capable of preventing central tubular beam from scaling, which comprises a kiln body, a central tubular beam and an ammonia distributor, wherein the central tubular beam is provided with a material bonding-preventing device consisting of a flexible baffle plate and a bracket; the flexible baffle plate is fixed above the central tubular beam by the bracket; and the flexible baffle plate is made in a size big enough to cover the upper part and the two sides of the central tubular beam. When accumulated in a certain weight, the materials falling onto the flexible baffle plate will fall off with the deformation of the baffle plate, the scaling-preventing effect is desirable, the machine-stop cleaning time is prolonged greatly, the normal and stable operation of production is ensured, and the production cost is reduced.

Description

Can prevent the tablets press that central tubular beam scabs

Technical field

The present invention relates to a kind of multiple fertile grain-making machine of phosphorus that is used to produce, relate to a kind of tablets press that prevents that central tubular beam from scabbing specifically.

Background technology

Desired tablets press in the multiple fertile device of present phosphorus, as shown in Figure 1, its central tubular beam 2 tops are provided with the rigidity taper blocking material plate 5 of a pointed shape of pagoda to prevent ramming material.In granulation process, by direction of arrow rotation among the figure, the wet stock of tubular reactor reaction is ejected in the tablets press through nozzle 3 kiln body 4 on carrying roller 1; In course of injection; Have the sub-fraction wet stock to be directly injected on central tubular beam 2 and the ammonia sparger 7, and the wet stock 6 in the tablets press is also constantly being shed to central tubular beam 2 and ammonia sparger 7 in operation process, wet stock can be adsorbed on the taper blocking material plate 5 of central tubular beam and ammonia sparger 7 set of surfaces are formed scar and rapid the accumulation grown up; Usually production can only be kept just needs about 2 hours to stop cleaning once; Otherwise can cause damage to central tubular beam, seriously hinder tablets press and make the material process, and each cleaning once needs more than 2 hours at least; Production can not normal and stable move, and driving rate can not get improving.

Summary of the invention

The objective of the invention is provides a kind of tablets press that prevents that central tubular beam from scabbing to the weak point that exists in the prior art, can prevent effectively that material from scabbing in central tubular beam and ammonia sparger, prolongs the parking clearance time, improves system's driving rate.

For realizing above-mentioned purpose; The present invention has adopted following technical scheme: it comprises kiln body, central tubular beam and ammonia sparger; Central tubular beam is provided with the Anti-caking device; Said Anti-caking device is made up of flexible blocking material plate and support, and flexible blocking material plate is fixed on the central tubular beam top by support, and the size of flexible blocking material plate can cover the top and the both sides of central tubular beam.Can landing when dropping on material on the flexible blocking material plate and running up to certainweight with the blocking material plate distortion, thereby be not easy to produce and scab and damage central tubular beam by pressure.

Above-mentioned flexible blocking material plate also covers top and the both sides to the part ammonia sparger that is positioned at central tubular beam one end at least, can prevent effectively that material from assembling on the ammonia sparger.

In order to improve the Anti-caking effect, to being fixed with rotation axis, said support is connected through swing arm and rotation axis along the kiln axon in the central tubular beam top; The outside of kiln body one end is provided with and can drives the swing arm reciprocating tilting mechanism of moving axis that rotates.Make reciprocally swinging through tilting mechanism drive swing arm and support, can the material that concentrate on the blocking material plate in time be shaken off.

Above-mentioned flexible blocking material plate is processed by the flexible rubber sheet.

Can know that by technique scheme the present invention is through the flexible blocking material plate of employing on central tubular beam and ammonia sparger, and blocking material plate can be scratched under the effect of tilting mechanism; Make the material of assembling in time to fall; Preventing scaring is effective, and the time of the cleaning of stopping prolongs greatly, can guarantee the operation of production normal and stable; System's driving rate can be increased to more than 90%, has reduced production cost.

Embodiment

Like Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, central tubular beam 2 tops are axially arranged with the bearing 22 that several are used to support rotation axis 13 along kiln body 4, and bearing 22 is provided with chock 11; Because the kiln body is longer; Rotation axis is made up of with minor axis 23 number segment length axle 13, and major axis 13 is in series through bolt 21 with minor axis 23, and minor axis 23 is fixed on the bearing 22 by chock 11; The support 12 of fixing flexible blocking material plate 8 is the crossbeam of a long strip shape; Support 12 laterally arranges with

rotation axis

13 and 23, is connected through swing arm 10 between every segment length's axle 13 and the support 12, and support 12 extends to outside the kiln body 4 at nozzle 3 ends of kiln body 4; And be hinged through bearing pin 20 at the connecting rod 9 of the swing arm of this end 10 with tilting mechanism, the flexible blocking material plate of being processed by sheet rubber 8 is fixed on the support 12 by bolt 14.The shape of flexible blocking material plate 8 such as Fig. 2, shown in Figure 4 are hung naturally and are covered to the top and the both sides 15 of a part of pipeline section of central tubular beam 2 both sides and ammonia sparger 7 by support 12 both sides.

Like Fig. 4, shown in Figure 6, tilting mechanism is made up of cylinder 18, crank 24 and connecting rod 9.Cylinder 18 is fixed on the frame 16 outside the kiln body 4 with crank 24; Crank 24 is fixed on the frame 16 through rotating shaft 19 and chock 17; Connecting rod 9 is and is horizontally disposed with, and two ends are hinged crank 24 the other ends and cylinder 18 pistons hinge with the swing arm 10 of support 12 outer ends respectively with crank 24.When cylinder 18 actions; Drive swing arms 10 and support 12 moving

axis

13,23 that rotates through crank 24, connecting rod 9 and make reciprocally swinging; Covering central tubular beam 2 promptly scratches with the flexible blocking material plate 8 on the ammonia sparger 7 back and forth; Can make to concentrate at its surperficial material and in time shake off, thereby can prevent effectively that material from assembling on its surface.
