Abstract
The invention discloses a rotary kiln, and relates to the technical field of rotary kiln manufacture. The rotary kiln comprises a kiln body obliquely arranged on a mounting seat and driven by a rotary driving device, wherein the kiln body consists of a kiln cylinder, and a front kiln hood and a rear kiln hood that are arranged at the two ends of the kiln cylinder; a feed port is formed in the rear kiln hood; the kiln cylinder is provided with a gas outlet pipe on a kiln wall close to the rear kiln hood; a gas inlet is formed in the front kiln hood; the kiln cylinder is provided with a discharge pipe on the kiln wall close to the front kiln hood; a material pushing strip distributed spirally is arranged on the inner wall of the kiln cylinder, and extends to the discharge pipe from a feed end of the kiln cylinder; and the kiln cylinder is provided with a plurality of material stopping rings on the kiln wall from a gas inlet end to the discharge pipe. Compared with the prior art, the rotary kiln can solve the problems that the conventional rotary kiln is low in heat utilization rate and gas can not enter smoothly.
Description
Technical field
The present invention relates to rotary kiln manufacturing technology field, especially a kind of for the rotary kiln in lithopone production line.
Background technology
In the production of lithopone, using rotary kiln to carry out calcining to the lithopone prepared is an important production link.Existing a kind of rotary kiln, this rotary kiln comprises the tilting kiln body driven by device for revolving and driving on mount pad, and described kiln body is made up of kiln cylinder and the Qian Yaogai and rear kiln lid being located at these kiln cylinder two ends; Described rear kiln covers and is provided with charging aperture, and described kiln cylinder is provided with escape pipe in the kiln wall of nearly described rear kiln lid; Described front kiln covers and is provided with fuel gas inlet, and described kiln cylinder is provided with discharge nozzle in nearly described front kiln lid kiln wall.In use there are the following problems for this rotary kiln: 1, due to the inner wall smooth of cylindrical shell, and the time that material stops in cylindrical shell is short, and heating effect is not obvious, and heat utilization efficiency is low; 2, because cylindrical shell included angle is excessive, and discharge nozzle is near fuel gas inlet, and material easily has the inwall be partly adhered between fuel gas inlet and discharge nozzle not easily to discharge in cylindrical shell in calcination process, hinders entering of combustion gas time serious.
Summary of the invention
Problem solved by the invention is to provide a kind of rotary kiln, enters with the low and combustion gas of the heat utilization efficiency solving existing rotary kiln the problem had some setbacks.
In order to solve the problem, the technical solution used in the present invention is: this rotary kiln comprises the tilting kiln body driven by device for revolving and driving on mount pad, and described kiln body is made up of kiln cylinder and the Qian Yaogai and rear kiln lid being located at these kiln cylinder two ends; Described rear kiln covers and is provided with charging aperture, and described kiln cylinder is provided with escape pipe in the kiln wall of nearly described rear kiln lid; Described front kiln covers and is provided with fuel gas inlet, and described kiln cylinder is provided with discharge nozzle in the kiln wall of nearly described front kiln lid, is provided with pusher bar described in pusher bar in spiral distribution extends to described discharge nozzle from the feed end of described kiln cylinder at described kiln cylinder inwall; Described kiln cylinder is provided with many blocking material rings in inlet end to the kiln wall at described discharge nozzle place.
In above-mentioned rotary kiln technical scheme, technical scheme can also be more specifically: the angle a of described kiln cylinder and horizontal direction is 3 ° ~ 5 °; The transition block of the arc that the transition block being provided with the arc abutted against with a blocking material ring and blocking material ring abut against is covered at described front kiln.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: the angle a due to kiln body and horizontal direction is set to the little oblique angle of 3 ° ~ 5 °, and interior kiln cylinder inwall is provided with pusher bar in spiral distribution, material is calcined and is not only pushed ahead in kiln body, large material can also be made to continue to calcine falling under gravity with pusher bar collision rift, increase the time of staying of material in kiln body, improve heat utilization efficiency; 2, kiln is covered with transition block and the polylith blocking material ring of ball-crown body, the material crossing discharge nozzle is fallen under the stop of blocking material ring, and the material crossing material ring flows from the transition block of arc to discharge nozzle under air inlet combustion gas effect, the fuel gas inlet of the smooth and easy the past kiln lid of combustion gas energy is entered, improves the heating effect of rotary kiln.
