Abstract

The utility model relates to a part of a feeding device transfer chute used for a lime kilning rotary kiln system, in particular to a rotary kiln feeding chute nozzle with a novel structure; the chute nozzle is characterized in that an elevation is added to the front end of the chute nozzle, and the nozzle surface is a structure of a shape opposite to 'L'. The chute nozzle effectively prevents the refractory cast material at the front end from being quickly worn and falling off caused by the scouring of limestone moving on the chute nozzle, thereby prolonging the service life of the refractory cast material.

Description

A kind of rotary kiln pan feeding of new structure is chewed with slipping

Technical field

The utility model relates to a kind of parts that are used for the pan feeding equipment transfer slide of lime calcining rotary system, is that a kind of rotary kiln pan feeding of new structure is chewed with slipping.

Background technology

It is by it lime stone to be sent into parts in the rotary kiln in the lime calcining rotary kiln device that slide is chewed, it is installed in the position (see figure 1) that transfer slide combines with rotary kiln, above chewing, slide is welded with anchoring piece, castable refractory is gone up in cast then, the effect of castable refractory is exactly to prevent from that the slide of metal material from chewing under about about 1000 ℃ environment temperature to cause damage that the lime stone after the preheating is chewed through slide and sent in the rotary kiln.Original slide is chewed section shape as shown in Figure 2, and several slides are chewed and formed a semicircle, and the front end of chewing that slips is the plane.

Production practices show that this slide is chewed because the washing away of lime stone, and the castable refractory of chewing front end that slips very easily weares and teares, comes off, and loses the protective effect that slide is chewed very soon, and maintenance will influence ordinary production again.For this reason, needing a kind of novel slide to chew to substitute original slide chews.

Summary of the invention

For solving the problem that prior art exists, the purpose of this utility model provides a kind of rotary kiln pan feeding of new structure and chews with slipping, the front end that this structure is chewed in slide is set up facade, can effectively prevent since chew lime stone that face moves above wash away the castable refractory that the slide that causes chews front end quick wearing and tearing, come off.

For addressing the above problem, the utility model by the following technical solutions:

A kind of rotary kiln pan feeding of new structure is chewed with slipping, and it is characterized in that: set up facade at the front end that slide is chewed, the face of chewing is

The shape structure.

Compared with prior art, the beneficial effects of the utility model are:

1, slips and to chew front end and increase facade, can play a protective role, prevent because the castable refractory that washes away of lime stone is chewed the edge from slide and begun to come off, thereby prolong the service life of castable refractory the castable refractory on its top;

2, front end is chewed in slide increases facade; when alleviating the wearing and tearing of watering material feeding effectively, coming off; even it is recessed to water some wearing and tearing of material feeding; the front end facade that slide is chewed can be so that lime stone be filled into the depression position to the obstruction of lime stone; become the friction between the lime stone, played the protection castable refractory equally and slip the effect of chewing.

Among the figure: 1, slip chew 2, anchoring piece 3, castable refractory 4, transfer slide 5, cylinder of rotary kiln

The specific embodiment

A kind of rotary kiln pan feeding of new structure is chewed with slipping, and chews 1 front end increase facade in slide, and the face of chewing is changed into by original intimate planar structure (see figure 2) Shape structure (Fig. 3) is seen Fig. 1, slips and to chew 1 binding site that is installed in transfer slide 4 and rotary kiln, slips to chew 1 lower end and connect cylinder of rotary kiln 5 tops.Be welded with anchoring piece 2 above slide chews 1, castable refractory 3 is gone up in cast then.The facade that 1 front end increases is chewed in slide; castable refractory 3 to its top can play a protective role; prevent because the castable refractory 3 that washes away of lime stone is chewed 1 edge from slide and begun to come off; thereby prolong the service life of castable refractory 3; even castable refractory 3 some wearing and tearing are recessed; 1 front end facade is chewed in slide can become the friction between the lime stone so that lime stone is filled into the depression position to the obstruction of lime stone, plays protection castable refractory 3 equally and slips 1 the effect of chewing.

Claims

1, a kind of rotary kiln pan feeding of new structure is chewed with slipping, and it is characterized in that: set up facade at the front end that slide is chewed, the face of chewing is

The shape structure.
