The utility model discloses long service life has certain elasticity moreover and plays certain cushioning effect, is difficult for causing the chaff broken, and drying rate is fast, and is effectual.

Description

Hot air ventilation structure of hot air dryer

Technical Field

The utility model relates to a desiccator technical field particularly, relates to a hot air drying machine hot-blast ventilation structure.

Background

The grain drier is mainly used for drying paddy and wheat, and can be used for drying crops such as rapeseeds and the like after being slightly improved. The grain drier consists of heat source, motor, axial flow fan, stacking rack and other parts. When the grain drier works, the motor drives the impeller of the axial flow fan to rotate at a high speed, hot air generated by burning coal or other fuels is sucked into the fan through the upper part of the air partition plate and forms mixed gas with cold air sucked into the fan from the lower part of the air partition plate, the mixed gas enters the stacking rack through the wind shielding pipe and then diffuses (the effect of the hot air reflecting plate is that the mixed gas diffuses more uniformly), when the mixed gas penetrates through a grain layer on the stacking rack, the temperature of grains is properly increased while a large amount of water vapor is taken away to gradually dry the grains, the temperature of the mixed gas can be adjusted through the temperature adjusting cover and the opening angle of the temperature adjusting plate, but the drying of a plurality of current circulating grain driers is not uniform, therefore, the drying needs to be repeated, and the drying efficiency of the grains is greatly reduced.

Disclosure of Invention

To the problem among the correlation technique, the utility model provides a hot air drying machine hot air ventilation structure to overcome the above-mentioned technical problem that current correlation technique exists.

In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:

the utility model provides a hot-blast ventilation structure of hot air drying machine, it includes the body, the body cross-section is the rhombus, body one end and air intake connection, and the other end is connected with the air outlet, the air intake all is the loudspeaker form with the air outlet, in the hot-blast wind channel of desiccator was arranged in to the body, the air intake still was connected with hot-blast wind regime, body rhombus both sides apex angle department all is provided with the vent, and the vent is inboard above two.

Further, the body is made of stainless steel, and the thickness of the body is 1-1.5 mm.

Further, the upper and lower top angles of the body are set between 45-60 degrees.

The utility model has the advantages that:

the utility model discloses long service life has certain elasticity moreover and plays certain cushioning effect, is difficult for causing the chaff broken, and drying rate is fast, and is effectual.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

According to the utility model discloses an embodiment provides a hot air drying machine hot air ventilation structure.

Referring to fig. 1-2, it includes body 1, body 1 cross-section is the rhombus, and body 1 one end is connected with air intake 2, and the other end is connected with air outlet 3, air intake 2 all is the loudspeaker form with air outlet 3, body 1 is arranged in the hot-blast wind channel of desiccator, and air intake 2 still is connected with hot-blast wind regime, body 1 rhombus both sides apex angle department all is provided with vent 4, and vent 4 is inboard on two.

The invention is used for drying grains, a body 1 is arranged in a hot air duct of a dryer, grains fall onto the body 1 from top to bottom in the hot air duct and then are divided into two sides, hot air enters from an air inlet 2 and exits from an air outlet 3, the hot air can heat air in the hot air duct through a vent 4 and take away water vapor in the process, so that the grains are dried, the air inlet 2 and the air outlet 3 both have horn-shaped streamline structures, the hot air is good in pneumatic layout and less in dissipation in the processes of entering the body 1 and exiting the body 1, the body 1 is made of stainless steel, the thickness of the body is 1-1.5mm, the grain impact force is endured for a long time, the service life is greatly prolonged, a certain elasticity plays a certain buffering role, and the grain falling too large impact force is avoided, so that grain shells are broken, in addition, the upper and lower top angles of the body 1 are arranged between 45 degrees and 60 degrees, if the angle is too large, the grain dispersion angle is too large, so that the grain dispersion angle is too far away from the ventilation opening 4, the drying effect is not good, if the angle is too small, the horizontal projection surface of the body 1 is too small, so that part of grains cannot fall onto the body 1, and the grain dispersion angle is too far away from the ventilation opening 4, and the drying effect is not good.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
