Abstract
The invention discloses a furnace atmosphere distributing device of a compound fertilizer dryer, which is a hollow metal pipe, wherein part of inner walls of the pipe is provided with a plurality of rippled grooves, and the rest of inner walls of the pipe are smooth surfaces. The furnace atmosphere distributing device of the compound fertilizer dryer has the following advantages of having simple structure, ensuring even hot flue gas in entering the cylinder body of the dryer, enabling all parts in the cylinder body of the dryer to sufficiently receive the heat of the flue gas, efficiently utilizing the dryer and improving the drying efficiency.
Description
Technical field
The present invention relates to a kind of furnace atmosphere distributing device of compound fertilizer dryer, be used to make the furnace gas in the compound fertilizer dryer to distribute equably, belong to chemical machinery field.
Background technology
At present, the flue gas of the heat that the oven dry thermal source of existing compound fertilizer dryer provides from combustion furnace, and the flue gas of heat is when entering dryer, because the caliber of the air inlet pipe of heat has only about 45% of drier body internal diameter, as shown in Figure 1, cause the flue gas of heat to have in entering drier body more than 2 meters, the hot flue gases of this section is insufficient with the heat exchange of material to be dried, this oven dry length more than 2 meters can not be made full use of, influenced the efficient of oven dry.
Summary of the invention
The objective of the invention is to address the above problem, a kind of furnace atmosphere distributing device of compound fertilizer dryer is provided, very even in the time of can making the flue gas of heat enter in the dryer, reach the effect of abundant oven dry.
Furnace atmosphere distributing device of compound fertilizer dryer of the present invention, it is the metal body of inner hollow, its part inside pipe wall be provided with a plurality of corrugation grooves, remaining inside pipe wall is a shiny surface.
Preferably, described device is the metal cylinder iron pipe of inner hollow, evenly is provided with a plurality of corrugation grooves continuously on 5/6ths the face of its inside pipe wall, and the fan-shaped angle that said inside pipe wall top forms is 300 °.
Equally preferably, described device is the metal cylinder stainless steel tube of inner hollow, evenly is provided with a plurality of corrugation grooves continuously on 3/4ths the face of its inside pipe wall, and the fan-shaped angle that said inside pipe wall top forms is 270 °.
Furnace atmosphere distributing device of compound fertilizer dryer of the present invention has following technique effect: simple in structure, and can make the flue gas of heat just very even when entering drier body, make interior all parts of drier body can both fully receive the heat of hot flue gases, make full use of dryer, improved drying efficiency.

Describe the present invention in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of compound fertilizer dryer and material feeding box in the prior art;
Fig. 2 is the structural representation of first embodiment furnace atmosphere distributing device of compound fertilizer dryer of the present invention;
Fig. 3 is the profile of Fig. 2;
Wherein, 1 is drier body, and 2 is material feeding box, and 3 is furnace atmosphere distributing device of compound fertilizer dryer.
The specific embodiment
As Fig. 2, shown in Figure 3, first embodiment of furnace atmosphere distributing device of compound fertilizer dryer of the present invention, furnace atmosphere distributing device is the metal cylinder iron pipe of an inner hollow, evenly be provided with a plurality of corrugation grooves continuously on 5/6ths the face of its inside pipe wall, the fan-shaped angle that the inside pipe wall top forms is 300 °, remaining inside pipe wall is a shiny surface, and the fan-shaped angle that the inside pipe wall top forms is 60 °.
First kind of embodiment of furnace atmosphere distributing device of compound fertilizer dryer of the present invention, the furnace atmosphere distributing device device is the metal cylinder stainless steel tube of inner hollow, evenly be provided with a plurality of corrugation grooves continuously on 3/4ths the face of its inside pipe wall, the fan-shaped angle that the inside pipe wall top forms is 270 °, and the fan-shaped angle that the inside pipe wall top forms is 90 °.
Furnace atmosphere distributing device of compound fertilizer dryer of the present invention is very simple in use, only need be placed in the material feeding box and get final product, the flue gas of heat is through furnace atmosphere distributing device of compound fertilizer dryer the time, can under the effect of furnace atmosphere distributing device, evenly distribute, make the flue gas of heat when entering drier body, just very become even.
