Abstract
The invention discloses a fluidized bed. The fluidized bed comprises a fluidized bed body (1), and an air inlet pipe (2) communicating with the fluidized bed body (1) through a pipe. The fluidized bed is characterized in that a gas distributor (3) is fixedly connected to the inner wall, near the pipe communication position of the air inlet pipe (2) and the fluidized bed body (1), of the fluidized bed body (1); a screen (4) is fixedly connected to the inner wall, far from the gas distributor, of the fluidized bed body (1); and a one-way valve is arranged on the air inlet pipe (2). After the structure is adopted, the gas distributor is fixedly connected to the inner wall, near the pipe communication position of the air inlet pipe and the fluidized bed body, of the fluidized bed body, and air enters the fluidized bed body through the gas distributor, so that the turbulent influence is reduced; the screen fixedly connected to the inner wall, far from the gas distributor, of the fluidized bed can screen materials in the fluidized bed body; and meanwhile, the gas distributor and the screen are used cooperatively to prevent the materials from agglomerating.
Description
Technical field
The present invention relates to a kind of fluid bed.
Background technology
Fluid bed is mainly used in carrying out drying to material, need during use to use air blast conveying gas, gas is by realizing carrying out drying to material from the air inlet pipe on fluid bed to air inlet in fluid bed body, the function singleness of fluid bed of the prior art, and air is directly sent into the intrinsic mode of fluid bed and can produce flow-disturbing, easily make material conglomeration.
Summary of the invention
The object of the invention is the function singleness solving fluid bed of the prior art, and air is directly sent into the intrinsic mode of fluid bed and can produce flow-disturbing, easily make the problem of material conglomeration.
The technical solution used in the present invention is: a kind of fluid bed, the air inlet pipe comprising fluid bed body and be communicated with fluid bed body tube, described fluid bed inner body wall is fixed with gas distributor near the pipe connectivity part of air inlet pipe and fluid bed body, and described fluid bed inner body wall is fixed with screen cloth away from gas distributor place.
As a further improvement on the present invention, described air inlet pipe is provided with check valve.
The invention has the beneficial effects as follows: after have employed this structure, described fluid bed inner body wall is fixed with gas distributor near the pipe connectivity part of air inlet pipe and fluid bed body, air by gas distributor laggard enter in fluid bed body, reduce the impact of flow-disturbing, the screen cloth that fluid bed inner body wall is connected away from gas distributor place can sieve the intrinsic material of fluid bed, and gas distributor and screening are with the use of preventing material conglomeration simultaneously.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Shown in figure: 1 fluid bed body, 2 air inlet pipe, 3 gas distributors, 4 screen clothes.
Detailed description of the invention
Below in conjunction with Fig. 1, the present invention is described further.
As shown in Figure 1, a kind of fluid bed, the air inlet pipe 2 comprising fluid bed body 1 and be communicated with fluid bed body 1 pipe, described fluid bed body 1 inwall is fixed with gas distributor 3 near air inlet pipe 2 and the pipe connectivity part of fluid bed body 1, described fluid bed body 1 inwall is fixed with screen cloth 4 away from gas distributor place, and described air inlet pipe 2 is provided with check valve.
After have employed this structure, described fluid bed inner body wall is fixed with gas distributor near the pipe connectivity part of air inlet pipe and fluid bed body, air by gas distributor laggard enter in fluid bed body, reduce the impact of flow-disturbing, the screen cloth that fluid bed inner body wall is connected away from gas distributor place can sieve the intrinsic material of fluid bed, and gas distributor and screening are with the use of preventing material conglomeration simultaneously.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention carries out all are dropped in protection scope of the present invention.
Claims (2)
1. a fluid bed, the air inlet pipe (2) comprising fluid bed body (1) and be communicated with fluid bed body (1) pipe, it is characterized in that described fluid bed body (1) inwall is fixed with gas distributor (3) near air inlet pipe (2) and the pipe connectivity part of fluid bed body (1), described fluid bed body (1) inwall is fixed with screen cloth (4) away from gas distributor place.
2. a kind of fluid bed according to claim 1, is characterized in that described air inlet pipe (2) is provided with check valve.
