Embodiment 1

[0032] like Figure 1-4 As shown, the mixing type lime kiln with the function of raw material classification processing includes a kiln body 1, and the kiln body 1 is provided with a distributing mechanism 2, and the distributing mechanism 2 is provided with at least two layers of distributing materials parallel to each other. plate 21, the distribution plate 21 is provided with a number of through holes 22 for the passage of raw materials, along the top to the bottom of the distribution mechanism 2, the through holes 22 on two adjacent distribution plates 21 gradually decrease, the The material distributing mechanism 2 is connected with a driving mechanism 3, and the driving mechanism 3 drives the material distributing mechanism 2 to rotate, so that raw materials are dispersed on different material distributing plates 21 according to different volumes.

Embodiment 2

[0041] like Figure 1-4 As shown, the mixing type lime kiln in this embodiment has the function of classifying and processing raw materials. 1. The inner wall is provided with a chute 11, one end of the limit rod 13 is detachably connected to the material distribution mechanism 2, and the other end is slidably arranged in the chute 11.

[0042] The mixing type lime kiln with the function of classifying raw materials in this embodiment adopts the structural form of setting a limit rod 13 at the bottom of the material distribution mechanism 2, so that the material distribution mechanism 2 is connected with the kiln body 1, and the structure is relatively simple and easy. The material distribution mechanism 2 is limited inside the kiln body 1, so that the material distribution mechanism 2 is in stable contact with the inner wall of the kiln body 1 during the rotation process, so as to ensure the smooth progress of the calcination process.

Embodiment 3

[0044] like Figure 1-4 As shown, the structure of the mixing lime kiln with raw material classification processing function of this embodiment is the same as that of Embodiment 2, the difference is that: the bottom of the chute 11 is provided with several bumps 12, and the top surface of the bumps 12 is in the shape of In the shape of an arc, the limiting rod 13 moves along the sliding groove 11 and passes through each of the protrusions 12 in turn.

[0045] In the mixed-material lime kiln with the function of raw material grading treatment in this embodiment, a bump 12 is provided at the bottom of the chute 11 in the kiln body 1, so that when the limit rod 13 passes through the bump 12, the material distribution mechanism 2 moves along the The displacement of the kiln body 1 in the height direction causes the material distribution mechanism 2 to vibrate during the rotation process, which speeds up the grading process of raw materials according to different volumes. The rela...

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...
