Background technique
Hothouse is the main equipment in spray drying device, by groups such as hot wind spiral case, hot-air distributor and hothouses
At.Wherein hot wind spiral case is in order to which dry-heat air water conservancy diversion is entered hothouse.But in the prior art, it is limited to hot wind spiral case sheet
The structure of body, often will appear that air inlet air quantity is big, the small phenomenon of air outlet air quantity, so that when dry-heat air enters hothouse not
It is very uniformly that then dry-heat air is easy to generate local eddy currents in hothouse, hot wind is uneven respectively, eventually leads to dry chamber interior walls
Powder there is a phenomenon where the viscous walls in part.
Utility model content
In view of the deficiencies of the prior art, the utility model discloses a kind of hot wind spiral cases of quantity-adjustable.
Technical solution used by the utility model is as follows:
A kind of hot wind spiral case of quantity-adjustable, spiral case 1 include the air duct for the zigzag shape that cross-sectional area is gradually reduced；Snail
Multiple regulating devices are installed in the air duct of shell；Regulating device includes the screw rod across wind path wall；Blade is fixed on screw rod；
Blade is located within air duct；Spanner is fixed in the other end of screw rod；The blade plane of spanner and blade is located at same level
On；Dial is also equipped on screw rod；Location nut is installed at scale disk center；Screw rod rotates in location nut；
Dial and spanner are located at except air duct.
Its further technical solution are as follows: the blade is rectangular sheet；Screw rod is fixed on the symmetrical shaft position of blade.
Its further technical solution are as follows: the air channel being gradually reduced along cross-sectional area, the length of blade are gradually reduced.
Its further technical solution are as follows: using the helix central point of spiral case as reference point, every two adjacent adjusting dress
Central angle between setting is equal.
Its further technical solution are as follows: the regulating device has 6~12.
Its further technical solution are as follows: the dial includes with graduated disk and direction instruction needle；Screw rod rotation
When turning, direction instruction needle is pointed up.
The beneficial effects of the utility model are as follows:
Air quantity is adjustable in the spiral case of the utility model, solves hot wind in hot wind spiral case in the prior art and distributes uneven ask
Topic.The utility model by rotation spiral case outside spanner rotate spiral case in blade, adjust air quantity, and rotating spanner when
It waits, can learn the rotational angle of spanner, and then the blade plane of exact inference blade is in air duct with the scale on reference mark disk
In angle.Then during equipment operation, the angle of each blade can be adjusted according to the actual situation, so that in entire air duct
Air quantity is uniform.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the schematic diagram of regulating device.
Fig. 4 is the schematic diagram of dial.
Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment.
Fig. 1 is the schematic diagram of the utility model.Fig. 2 is the top view of Fig. 1.As shown in Figure 1 and Figure 2, spiral case 1 includes section
The air duct for the zigzag shape that area is gradually reduced.Multiple regulating devices 2 are installed in air duct.
Regulating device 2 has 6~12, and in the embodiment shown in fig. 1, spiral case 1 is equipped with 6 regulating devices 2.Adjust dress
Set 2 in spiral case 1 position uniformly install.I.e. using the helix central point of spiral case 1 as reference point, every two adjacent adjusting dress
The central angle set between 2 is equal.
As shown in FIG. 1 to 3, regulating device 2 has the screw rod 3 including passing through wind path wall.One end of screw rod 3 passes through the first wind
After road wall 10, it is positioned on the second wind path wall 11 by location nut 6.
Blade 4 is fixed on screw rod 3.Blade 4 is located within air duct.Blade 4 is rectangular sheet, and screw rod 3 is fixed
In the symmetrical shaft position of blade 4.The width of blade 4 is less than the width in air duct namely the first wind path wall 10 and the second wind path wall 11
The distance between.When screw rod 3 rotates, blade 4 can be rotated with the rotation of screw rod 3.When the rotation of blade 4 is vertical to blade plane
When the direction of the tangent line of air duct helix, the length of blade 4 and the height in air duct are equal, and blade 4 is big by air duct section at this time
Partial occlusion is lived, if the tangent line of blade 4 rotation to blade plane and air duct helix is in a certain angle, blade 4 is by air duct
A part of section shelters from.Adjust the size of above-mentioned angle, so that it may adjust the degree that blade 4 blocks air duct.
Since the air duct of spiral case 1 is zigzag shape, and air duct cross-sectional area is gradually reduced, thus it is matched, along wind
In the fixed multiple regulating devices 2 in road direction, the length of blade 4 is gradually reduced.
Spanner 7 is fixed in the other end of screw rod 3.Dial 5 is also equipped on screw rod 3.Dial 5 and spanner 7
Except air duct.Dial 5 is located between first wind path wall 10 in air duct and spanner 7.
Spanner 7 and blade 4 are located in same level.When rotary spanner 7, it can be rotated with movable vane piece 4, and spanner
7 direction can indicate the rotation direction of the blade plane of blade 4.
Dial is equipped with location nut 6 at 5 center.Screw rod 3 can rotate in location nut 6.Fig. 4 is dial
Schematic diagram.As shown in figure 4, dial 5 includes with graduated disk 8 and direction instruction needle 9.When screw rod 3 rotates, direction instruction
Needle 9 remains pointing to the direction of top, to guarantee that dial direction is constant, has angle reference.Then rotating spanner 7 when
It waits, can learn the rotational angle of spanner 7 with the scale on reference mark disk 5, and then infer the blade plane of blade 4 in air duct
In angle.Then during equipment operation, the angle of each blade can be adjusted according to the actual situation, so that in entire air duct
Air quantity is uniform.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
