Example Embodiment

[0031] Example 1

[0032] Such as Figure 1-4 As shown, the mixed lime kiln with the function of grading processing of raw materials includes a kiln body 1, in which a material distributing mechanism 2 is provided, and at least two layers of material distributing parallel to each other are provided in the material distributing mechanism 2 A plurality of through holes 22 for the passage of raw materials are provided on the dividing plate 21. Along the top to the bottom of the dividing mechanism 2, the through holes 22 on two adjacent dividing plates 21 gradually decrease. The distributing mechanism 2 is connected with a driving mechanism 3, and the driving mechanism 3 drives the distributing mechanism 2 to rotate, so that the raw materials are dispersed on different distributing plates 21 according to different sizes.

[0033] In the mixed lime kiln with the function of raw material classification processing in this embodiment, the kiln body 1 is provided with multi-layer distribut...

Example Embodiment

[0040] Example 2

[0041] Such as Figure 1-4 As shown, the mixed lime kiln with the function of grading processing of raw materials of this embodiment has the same structure as embodiment 1, except that at least two limit rods 13 are provided at the bottom of the distributing mechanism 2, and the kiln body 1 is provided with a sliding groove 11 on the inner wall, one end of the limiting rod 13 is detachably connected with the material distributing mechanism 2, and the other end is slidably arranged in the sliding groove 11.

[0042] The mixed lime kiln with the function of grading processing of raw materials in this embodiment adopts a structure in which a limit rod 13 is arranged at the bottom of the distributing mechanism 2, so that the distributing mechanism 2 is connected with the kiln body 1. The structure is simpler and easier The material distributing mechanism 2 is restricted inside the kiln body 1, so that the material distributing mechanism 2 is in stable contact with t...

Example Embodiment

[0043] Example 3

[0044] Such as Figure 1-4 As shown, the mixed lime kiln with the function of raw material classification processing in this embodiment has the same structure as the embodiment 2, except that the bottom of the chute 11 is provided with a number of bumps 12, and the top surface of the bumps 12 is Arc-shaped, the limiting rod 13 moves along the sliding groove 11 and passes through each of the bumps 12 in turn.

[0045] In the mixed lime kiln with the function of grading processing of raw materials in this embodiment, a protrusion 12 is provided at the bottom of the chute 11 in the kiln body 1, so that when the limit rod 13 passes the protrusion 12, the material dividing mechanism 2 The height direction of the kiln body 1 is displaced, causing the distribution mechanism 2 to shake during the rotation, which speeds up the classification of raw materials according to different sizes. At the same time, due to the shaking of the distribution mechanism 2, it is also ben...

Abstract

The invention relates to the field of production of lime and particularly relates to a mixing type lime kiln with a raw material graded treatment function. The mixing type lime kiln comprises a kiln body, wherein a material distributing mechanism is arranged in the kiln body, at least two layers of mutually-parallel material distributing plates are arranged in the material distributing mechanism,a plurality of through holes for enabling raw materials to pass through are formed in the material distributing plates, the through holes in adjacent two material distributing plates are lessened gradually from the top of the material distributing mechanism to the bottom of the material distributing mechanism, the material distributing mechanism is connected with a driving mechanism, and the driving mechanism drives the material distributing mechanism to rotate. The raw materials can be dispersed on different material distributing plates according to different sizes, the proceeding of a calcination process is accelerated, and the consumption of fuel is lowered; and meanwhile, the driving mechanism is further arranged to drive the material distributing mechanism to rotate, thus, relative positions between the fuel and limestone are changed during the rotation of the raw materials in the material distributing mechanism in the calcination process, the proceeding of the calcination processis further accelerated, the production efficiency of the lime kiln is increased, and then, resource expenditure is reduced, so that the mixing type lime kiln has the effects of high yield and energysaving.

Description

technical field [0001] The invention relates to the field of lime production, in particular to a mixing type lime kiln with the function of classifying raw materials. Background technique [0002] As an important auxiliary material in industrial production, lime is widely used in many industries such as metallurgy, chemical industry, environmental protection, building materials, etc. At present, the commonly used mixing type lime kiln for preparing lime generally uses coal, coke and other solid fuels to calcinate limestone to prepare lime. The current mixing Type lime kiln generally adopts the structure of kiln top feeding and kiln bottom ash discharge. The interior of the kiln body is a space structure connected from top to bottom. The mixed fuel and limestone are introduced into the kiln body with grate through the material distribution mechanism. , so that the fuel and limestone are sprinkled on the grate, and the air is introduced from the lower side of the grate to ma...
