Abstract
The utility model discloses a kind of fluid bed air-intake device, including blast pipe, air-inlet cavity, air-inlet cavity tangential direction is provided with the blast pipe connected with air-inlet cavity inside, and air distribution plate is installed in air-inlet cavity.The utility model employs tangent line air inlet mode, is compared with traditional central air inlet mode, can improve the uneven state of air flow method, improves the uniformity of EAT, improves rate of heat exchange, Improving The Quality of Products.
Description
Technical field
The utility model is related to production and processing field, and in particular to a kind of fluid bed air-intake device.
Background technology
Fluid bed is one of important equipment in industrial production particularly pharmaceutical industry, is mainly used in drying, granulation, is coated
Etc. technical process.Fluid bed is mainly made up of parts such as air-inlet cavity, product pot, propagation chamber, filter chambers.Air-inlet cavity is played will be entered
The gas of fluid bed is dispersed, change traffic direction, the effect of fluidisation material.It is the form of air flow method in air-inlet cavity, uniform
Property, operation of the stability to fluid bed that changes airflow direction there is strong influence, processing performance to fluid bed and made
Standby product quality has very important influence.
The air-inlet cavity of current fluid bed mainly uses traditional central air inlet mode, and process is as follows：Intake stack with enter
The vertical mode in wind chamber horizontally enters into air-inlet cavity, after the cavity wall perpendicular acting on air-inlet cavity opposite, change airflow direction, vertically to
On through air distribution plate enter product pot in, by product pot in material fluidized, and further complete granulation, dry etc.
Technical process；
When the air-inlet cavity of the type works, air-flow linearly enters vertical with the air-inlet cavity cavity wall of distal end after air-inlet cavity
After effect, change airflow direction, vertically upward into product pot in, by product pot in material fluidized.But in this kind
In the case of, enter the air flow method and uneven of product pot through air distribution plate, but from the distal end with blast pipe distance to
The trend that near-end is gradually decreased.This air inlet mode has the disadvantage that：Air flow method is uneven, heat exchanger effectiveness is poor, enter wind-warm syndrome
Spend bad uneven, fluid effect, the more difficult control of technique, product quality and reappearance poor.
The content of the invention
The purpose of this utility model, exactly provides a kind of fluid bed air-intake device to solve the above problems, and can have
Effect ground improves the uneven situation of air flow method, improvement and invites exchange efficiency and the uneven problem of EAT, Improving The Quality of Products and
The reappearance of technique.
What the purpose of this utility model was realized in：
A kind of fluid bed air-intake device of the present utility model, including blast pipe, air-inlet cavity；
The blast pipe is arranged in air-inlet cavity tangential direction and is connected with air-inlet cavity inside.
Air distribution plate is also equipped with the air-inlet cavity, the air distribution plate is installed on air-inlet cavity top and is put down with ground
OK.
The utility model employs tangent line air inlet mode, is compared with traditional central air inlet mode, can improve air-flow point
The uneven state of cloth, improves the uniformity of EAT, improves rate of heat exchange, Improving The Quality of Products.
Brief description of the drawings
Fig. 1 is the structural representation of fluid bed；
Fig. 2 is conventional fluidization bed air-flow patterns；
Fig. 3 is the air-flow patterns of fluid bed air-intake device of the present utility model.
Wherein, arrow size represents the size cases of throughput.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The basic structure that conventional fluidization bed is shown in Fig. 1 and Fig. 2, Fig. 1 is referred to, the direction of arrow in Fig. 2 shows
The air-flow patterns by the way of central air intake, it can be seen that the air-flow size distribution of traditional fluid bed air-inlet cavity 2
It is uneven.
Fig. 3 is fluid bed air-intake device of the present utility model, including blast pipe 1, air-inlet cavity 2 and air distribution plate 4 are (in figure
Be not drawn into), blast pipe 1 is installed on the tangential direction of air-inlet cavity 2, the air-flow in blast pipe 1 enter the inside of air-inlet cavity 2 after in air intake
The inwall effect in chamber 2 is lower to change movement locus, forms interior rotational airflow, and the interior rotational airflow enters product pot 3 by air distribution plate 4
Inside carry out fluidisation work.
The utility model employs tangent line air inlet mode, is compared with traditional central air inlet mode, can improve air-flow point
The uneven state of cloth, improves the uniformity of EAT, improves rate of heat exchange, Improving The Quality of Products.
Above example is only for illustration of the utility model, rather than to limitation of the present utility model, relevant technical field
Technical staff, in the case where spirit and scope of the present utility model are not departed from, various conversion or modification can also be made, because
This all equivalent technical scheme should also belong to category of the present utility model, should be limited by each claim.
