Abstract

The utility model discloses a transportation chute of a rotary kiln. The transportation chute comprises a base and a chute body, wherein the chute body is arranged on the base; an upper shell of the chute body is reversed-taper-shaped, and a lower shell of the chute body is cylindrical; an outlet communicated with an inlet of the rotary kiln is formed on one side of the lower part of the chute body, and the bottom part of the chute body is an inclined plane; a plurality of prefabricated blocks are paved on the inner wall of the shell and comprise a steel base as well as metal anchoring pieces and wear-resisting pouring materials on the steel base; and the steel base is connected with the inner wall of the shell. As the transportation chute of the rotary kiln is provided with the prefabricated blocks, the service life of refractory materials of the transportation chute can be effectively prolonged.

Description

A kind of rotary kiln transfer slide

Technical field

The utility model relates to rotary kiln, particularly a kind of rotary kiln transfer slide.

Background technology

Rotary kiln is a kind of comparatively common industrial furnace, rotary kiln generally is comprised of preheater, kiln, cooler, calcination system, induction system etc., what wherein connect preheater and rotary kiln body is transfer slide, has built refractory material by laying bricks or stones in preheater, rotary kiln, cooler and the transfer slide.

In production practices, the anti-material of transfer slide is owing to being subject to washing away continuously of material, so often anti-material wear damage is comparatively serious, often therefore rotary system can can't normally be produced and be forced to stop the kiln maintenance.The anti-material of present transfer slide adopts wear-resistant castable as refractory material usually, also has the local method of building the cofferdam by laying bricks or stones that adopts to carry out anti-material design application, but because the limitation that exists separately, overall result of use is often not ideal enough.

Summary of the invention

The purpose of this utility model is to design a kind of rotary kiln transfer slide, can prolong the transfer slide service life of refractory material.

For achieving the above object, the technical solution of the utility model is:

A kind of rotary kiln transfer slide, it comprises, pedestal; The chute body is arranged on the pedestal, and its upper body is inverted cone shape, and lower case is cylindricality, and bottom one side has the outlet that can be communicated with the rotary kiln import, and the bottom is the inclined-plane; Inner walls is laid some prefabricated sections, this prefabricated section comprise the steel pedestal and on metal anchorage, wear-resistant castable, the steel pedestal is connected with inner walls.

Further, described prefabricated section steel pedestal and inner walls are welded and fused.

Again, described prefabricated section is arranged at the inner walls interval, is built antiwear refractory brick or castable in the interval by laying bricks or stones.

Have, chute body inner walls vertical component described in the utility model is spaced apart up and down the thickness of 2～3 blocks of prefabricated sections between two blocks of prefabricated sections again.

Described chute body inner walls sloping portion is spaced apart up and down the thickness of 1～1.5 block of prefabricated section between two blocks of prefabricated sections.

In addition, pedestal described in the utility model is divided into roller.

The beneficial effects of the utility model:

1. because prefabricated section is anti-material factory fires by the burning process of anti-the material in advance and form, the heat when need not to recycle the rotary kiln baker is fired, so anti-wear performance has sufficient assurance.

2. prefabricated section is connected with the transfer slide housing, forms firm foundations, and building anti-material by laying bricks or stones at these prefabricated sections has very strong stability.

3. the anti-material at place, slope is washed away the most serious; therefore the interval between this part prefabricated section with the thickness of 1-1.5 piece prefabricated section for well; even purpose is this part to be worn and to form shock proof wearing layer during also having material and being filled into, the anti-material in protection bottom is no longer impaired.

4. because transfer slide is irregularly shaped, thus can be with the angular adjustment of carrying out irregularly shaped place than the prefabricated section of small body type, and anti-material is built by laying bricks or stones comparatively flexible.

The specific embodiment

Referring to Fig. 1～Fig. 3, a kind of rotary kiln transfer slide of the present utility model, it comprises, pedestal 1; Chute body 2 is arranged on the pedestal 1, and its upper body 21 is inverted cone shape, and lower case 22 is cylindricality, and bottom one side has the outlet 221 that can be communicated with rotary kiln 200 imports, and bottom 23 is the inclined-plane; Inner walls is laid some

prefabricated sections

3,3 ', 3 ", this prefabricated section 3 (take prefabricated section 3 as example, lower with) comprise steel pedestal 31 and on metal anchorage 32, wear-resistant castable 33, steel pedestal 31 is connected with inner walls.

Further, described prefabricated section 3 steel pedestals 31 are welded and fused with inner walls.

Again, described prefabricated section 3 is arranged at the inner walls interval, is built antiwear refractory brick or castable in the interval by laying bricks or stones.

Described chute body 2 inner walls vertical components are spaced apart up and down the thickness of 2～3 blocks of prefabricated sections between two blocks of prefabricated sections.Described chute body 3 inner walls sloping portions are spaced apart up and down the thickness of 1～1.5 block of prefabricated section between two blocks of prefabricated sections.

Described pedestal 1 is divided into roller 4.

Rotary kiln is a kind of comparatively common industrial furnace, the utility model avoided that the on-the-spot baking quality of original employing wear-resistant castable is difficult to guarantee defective, " cofferdam " technology of also having solved can only be used the problem at privileged site, the transfer slide service life of refractory material is greatly improved, can bring very large benefit to the rotary kiln stable smooth operation, and very simple, therefore have extremely strong application value.
