Abstract
The utility model relates to an embedding radial air supply arrangement for the rotary kiln and includes a cylindrical kiln body and a blower fan arranged on the kiln body. A plurality of air nozzles are evenly distributed on the kiln body along the axial direction and the peripheral direction. The air nozzles pass the kiln body on the radial direction, a wind duct is arranged at the outer end of the air nozzles, the wind duct is communicated with the outlet of the blower fan; a control valve is arranged on each of the air nozzles. The utility model has the advantages of that the air is evenly supplied into the kiln body through the evenly distributed air nozzles, the air quantity of each nozzle can be controlled by the control valve, and thus the uniform temperature can be achieved at each point in the kiln, which avoids the agglomeration at high temperature point and eliminates the negative effect caused by this factor. Due to the evenly-supplied air, the burning of the fuel is uniform and sufficient, which avoids energy waste and air pollution caused by the exhaust emission. Additionally, the air is preheated in the wind duct, which can save energy.
Description
Technical field
The utility model relates to rotary kiln, specifically is radially air supply device of a kind of flush type rotary kiln.
Background technology
The air supply mode of existing rotary kiln is axial air feed.Its shortcoming is to concentrate owing to being blown into air point, form localized hyperthermia's band easily nearby, and form along the bonding ring formation of kiln body inwall in this high temperate zone, the formation of this ring formation influences the percent of pass of material (product) of being heated in the kiln, reduced output, can not produce when serious; Because air feed is inhomogeneous, causes the kiln fuel combustion inhomogeneous, the fuel combustion that has is insufficient, causes energy waste and environmental pollution.
Summary of the invention
The purpose of this utility model just provides radially air supply device of a kind of flush type rotary kiln, the localized hyperthermia that nearby forms easily that exists with the solution prior art is with, and form along kiln body inwall and the ring formation bonding with it in this high temperate zone, the formation of this ring formation influences the percent of pass of material (product) of being heated in the kiln, reduced output, can not produce when serious; Because air feed is inhomogeneous, causes the kiln fuel combustion inhomogeneous, the fuel combustion that has is insufficient, causes energy waste and environmental pollution problems.
The technical solution of the utility model is: comprise cylindrical shape kiln body and be installed in the blower fan that covers on the kiln body, on described kiln body vertically and be evenly distributed in a plurality of gas and chew, this gas is chewed and is radially passed described kiln body, the outer end of chewing at this gas is provided with the air channel, and this air channel communicates with the outlet of described blower fan; Chew at each described gas and to be provided with control valve.
Described gas is chewed vertically and is evenly set in a row, is uniformly distributed with many exhausts along the circumference and chews, and the gas between the adjacent row is chewed mutual dislocation; Described air channel is by main air duct and divide branch air duct to form, main air duct is the annular around the external side face of described kiln, each divide branch air duct along the kiln axon to setting, the one end communicates with described main air duct, each divides the described gas of branch air duct covering one row to chew, and the regulating handle that described gas is chewed control valve seals the outside that passes described minute branch air duct.
Inlet at described each branch branch air duct is equipped with branch's control valve.
The inner that described gas is chewed protrudes from kiln body inner surface.
The utility model has the advantages that: chew even air feed in the kiln body by the gas of even layout, and regulate the air quantity that each gas is chewed by each control valve, can make the temperature of each position in the kiln even, avoid because the ring formation that localized hyperthermia's band forms has been eliminated the adverse effect of bringing thus to producing.Because air feed can make fuel combustion evenly, fully equably, has avoided energy waste and the toxic emission pollution to atmosphere.In addition, air is preheated in the air channel, has energy-saving effect.

The specific embodiment
Referring to Fig. 1～Fig. 3, the utility model comprises cylindrical shape kiln body 1 and is installed in the blower fan 2 that covers on the kiln body, on described kiln body 1 vertically and be evenly distributed in a plurality of gas and chew 5, this gas is chewed 5 and is radially passed described kiln body 1, chew 5 outer end at this gas and be provided with main air duct 3 and divide branch air duct 4, blower fan 2 is housed in main air duct 3 outsides.Chew at each described gas and to be provided with control valve 6 on 5.Inlet at described each branch branch air duct 4 is equipped with branch's control valve 7.Can also a valve (not shown) be installed in the outlet of blower fan 2, be used to regulate total blast volume.
Described gas is chewed the inner of 5 and is preferably protruded from the inner surface of kiln body 1, so that make it go deep into certain distance in the heated material, and the too high and ring formation of the temperature of charge of avoiding approaching kiln body 1 inner surface.
Described gas chew 5 along kiln body 1 axially evenly at interval and set in a row, chew 5 along the many exhausts of being evenly distributed in of kiln body 1, the gas between the adjacent row is chewed 5 mutual dislocation.Described main air duct 3 is the annular around described kiln body 1 outer peripheral face, each divides the axial setting of branch air duct 4 along kiln body 1, the one end communicates with described main air duct, each divides the described gas of branch air duct 4 coverings, one row to chew 5, the regulating handle that described gas is chewed control valve 6 seals the outside that passes described minute branch air duct 4, regulates with convenient.
The utility model is in when operation, and blower fan is pressed into main air duct 3 with air, enters each minute branch air duct 4 then, chews 5 and sends in the kiln body 1 by each control valve 6 is gentle again.Can make each gas chew 5 air inflow to meet the demands by regulating each valve 6 respectively, and then reach the uniform purpose of temperature that makes in the kiln body.
