Abstract

The utility model provides a wind dividing device of a dry kiln capable of evenly delivering hot. The wind dividing device comprises a kiln body, a hot supplying main pipe, two hot supplying square wind pipes and a main wind diving pipe, wherein one end of each hot supplying square wind pipe is connected with the hot supplying main pipe outside the top of the kiln body, the other end of each hot supplying square wind pipe circles the two sides of the kiln body and is divided into two branch hot supplying pipes to be connected with the inner part of the kiln body, the main wind diving pipe is assembled at the wind discharging ends of the branch hot supplying pipes, the assembled main wind diving pipe is arranged in the kiln body, a wind inlet of the main wind diving pipe is divided into four mutually-independent wind dividing devices by a plurality of flow deflectors of the main wind diving pipe, and each independent wind dividing device is evenly divided into four wind outlets by the independent flow deflectors. By adopting the scheme, the main wind dividing pipe is provided with 32 wind outlets, and the hot wind can be evenly delivered into the kiln body, so that the wind dividing device can lead a final green body in the kiln body to be evenly heated, and can prevent the green body from having the defects such as the deforming, the cracking and the like caused by the uneven drying and heating. By adopting the scheme, the wind dividing device is simple in structure, and greatly improves the production speed of the dry kiln and the product quality after production.

Description

A kind of heat dry kiln air devider uniformly that send

Technical field:

The utility model relates to the kiln technical field, refers in particular to a kind of heat dry kiln air devider uniformly that send.

Background technology:

Contain chemical bonding water, atmosphere adsorbed water and Free water in the ceramic body of employing dry pressing, dry effect is exactly the process of removing base substrate internal freedom water, gives the base substrate certain intensity simultaneously, makes base substrate adapt to the requirement of procedures such as transportation, glazing.In the body drying process, discharge along with Free water, whole base substrate shrinks, because of the particle of blank has certain orientation, the anisotropy that has caused dry contraction, this opposite sex have caused the difference of base substrate ectonexine and each several part shrinkage factor, thereby have produced internal stress, when this internal stress during greater than the yield value of moulding state base substrate, the base substrate cracking that will deform.The drier heat supply is that hot blast is sent in the drier by square airduct from the drier two ends, will cause the temperature at drier two ends higher like this than middle, dry base substrate is heated inhomogeneous, and then its internal stress is concentrated more easily, thereby produces base substrate strain cracking in contraction.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, send heat dry kiln air devider uniformly.

For achieving the above object, technical scheme provided by the utility model is: a kind of heat dry kiln air devider uniformly that send, it includes the kiln body, heat supply is responsible for, heat supply side's airduct, wherein, heat supply side's airduct is two, the one end all is connected the heat supply of kiln body top outer and is responsible for, the other end is connected in the kiln body around being divided into two branch line heating tubes to kiln body two rear flank, it also includes the main airduct that divides, the main airduct that divides is assemblied in branch line heating tube outlet air end, the main airduct that divides after the assembling is positioned at the kiln body, and the main airduct air inlet that divides is divided into four separate independent air deviders by the main airduct flow deflector that divides, and independent air devider evenly is divided into diffusing air port, four roads by independent flow deflector again.

The outlet in described diffusing air port all is positioned at the same side of branch line heating tube.

The utility model is after having adopted such scheme, at first will lead branch airduct air inlet and be divided into four parts by main branch airduct flow deflector, hot blast evenly is divided into four parts to be sent in the kiln body, in four independently independent air deviders, evenly be divided into diffusing air port, four roads with independent flow deflector again, be divided into twice by dividing plate again in diffusing exit, air port, thus, the main airduct that divides has 32 road air outlets, hot blast just can evenly be sent in the kiln body, final base substrate in the kiln body is heated evenly, prevents the base substrate defectives such as distortion that inequality causes, cracking of being heated because of drying.Adopt simple in structure behind this programme, and promoted the speed of production of dry kiln greatly and produce after product quality.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 divides the structural representation of airduct for the utility model master.

Fig. 3 is the vertical view of Fig. 2.

Reference numeral: the 1-heat supply person in charge, 2-heat supply side airduct, 3-master divide airduct, 4-kiln body, 5-branch line heating tube, 6-master to divide airduct flow deflector, 7-independence air devider, 8-independence flow deflector, the diffusing air port of 9-, 10-dividing plate, 11-air outlet.

The specific embodiment:

The utility model is described in further detail to accompanying drawing 3 below in conjunction with accompanying drawing 1, preferred embodiment of the present utility model is: the described dry kiln air devider of present embodiment includes kiln body 4, heat supply is responsible for 1, heat supply side's airduct 2, wherein, heat supply side's airduct 2 is two, the one end all is connected the heat supply of kiln body 4 top outer and is responsible on 1, the other end is connected in the kiln body 4 around being divided into two branch line heating tubes 5 to 4 liang of rear flank of kiln body, it also includes the main airduct 3 that divides, the main airduct 3 that divides is assemblied in branch line heating tube 5 outlet air ends, the main airduct 3 that divides after the assembling is positioned at kiln body 4, and main airduct 3 air inlets that divide are divided into four separate independent air deviders 7 by the main airduct flow deflector 6 that divides, independent air devider 7 evenly is divided into diffusing air port 9, four roads by independent flow deflector 8 again, diffusing 9 exits, air port are divided into twice air outlet 11 by dividing plate 10, and the outlet in the air port 9 of loosing all is positioned at the same side of branch line heating tube 5.After having adopted such scheme, at first will lead branch airduct 3 air inlets and be divided into four parts by main branch airduct flow deflector 6, hot blast evenly is divided into four parts to be sent in the kiln body 4, in four independently independent air deviders 7, evenly be divided into diffusing air port 9, four roads with independent flow deflector 8 again, be divided into twice by dividing plate 10 again in 9 exits, diffusing air port, thus, the main airduct 3 that divides has 32 road air outlets 11, hot blast just can evenly be sent in the kiln body 4, final base substrates in the kiln body 4 are heated evenly, prevent the base substrate defectives such as distortion that inequality causes, cracking of being heated because of drying.Adopt simple in structure behind this programme, and promoted the speed of production of dry kiln greatly and produce after product quality.
