Abstract

The utility model relates to an even blowing-in structure used for the dryness field and the ventilation field. When the existing blowing-in structure works, the existing disadvantage is that the wind rate of the middle position of a diffuser is big, but the wind rate of both sides of the diffuser is small. The wind rate of the end of an angular box is big, but the wind inlet end of the angular box is small, which lead to the entire material cross section to bear nonuniform wind. Therefore, the working quality of the drying machine is influenced. The even blowing-in structure is modified on the base of the existing blowing-in structure, and the diffuser and the angular-shaped box are added with partition plates properly to make the even blowing-in structure to be divided into a plurality of ventilating ducts, and moreover, a movable partition plate is arranged. The ventilation of each channel can be adjusted, and therefore, the baking homogeneity of the material of the drying machine is improved.

Description

Even blowing-in structure

When relating to the aeration-drying material, the utility model can send into the device of even air quantity.

No dividing plate in existing similar technology and the equipment, diffuser in its air-supply structure and horn shape box is perhaps only installed split-wind plate in diffuser, do not reach the purpose of quantitative and even air-supply like this.The shortcoming that this structure in use exists is that the air quantity of diffuser middle part is big, and the both sides air quantity is little; The terminal air quantity is big in the horn shape box, and the air intake air quantity is little.Not only drying efficiency is low, and the dried material quality is also relatively poor.

The purpose of this utility model is to solve horn shape boxlike dryer uneven air problem.

The balanced ventilation structure is to install some stationary barriers 6 in diffuser 5 additional, at its air intake rotating active clapboard 7 is installed.Rotate to adjust handle 1, the ventilation in each air channel is reached unanimity, or determine ventilation as required, can evenly deliver to purpose in each horn shape box to air to reach.In horn shape box 3, install the stationary barrier 2 of some bendings additional, rotating active clapboard 4 is installed at its air intake.By the position of rotating adjusting handle change active clapboard 4 ventilation in each air channel in the horn shape box is reached unanimity equally, or determine air quantity as required.Make the wind energy of last output contact material equably.

The utility model only needs to install additional on demand oven dry uniformity, the drying efficiency that some dividing plates promptly can improve drying machine on original equipment, guarantee materials quality.

Fig. 6, Fig. 7: asymmetric shape diffuser air-supply structure schematic diagram

A kind of symmetric figure wind pushing mechanism that provides among the figure adds 2～8 stationary barriers of making of sheet metal 6 of weldering in diffuser 5.But the active clapboard 7 at diffuser air inlet end and the every all hinged transfer of stationary barrier 6 makes diffuser be divided into several air channels.Rotate and adjust handle 1, it is moving to drive active clapboard 7, can adjust the wind supply quantity in each air channel.Same 1～4 bending shape stationary barrier of making of sheet metal 2 of weldering that in horn shape box 3, adds, but active clapboard 4 at horn shape box air inlet end and the hinged transfer of stationary barrier, make the horn shape box be divided into several air channels, same by adjusting handle rotation active clapboard 4, can adjust the wind supply quantity in each air channel.

Fig. 3～5 have provided straight bending, tiltedly the stationary barrier of bending and the bending of circular arc bending.Fig. 6 Fig. 7 is the air-supply structure of two kinds of asymmetric diffusers.

Claims

1, a kind of air-supply structure is characterized in that installing stationary barrier in the diffuser additional, makes it be separated into 3～9 air channels.

2, according to the air-supply structure of claim 1, it is characterized in that installing additional in the horn shape box stationary barrier of bending shape, make it be separated into 2～5 air channels.

3, according to claim 1,2 air-supply structure, it is characterized in that the air inlet position of diffuser and horn shape box is equipped with the transfer active clapboard, the adjustment handle hinged with it handled.

4,, it is characterized in that the stationary barrier in the horn shape box can be the bending dividing plate of straight bending, oblique bending, circular arc bending according to the air-supply structure of claim 2.
