Problems solved by technology

However, the working mode of the boiling dryer itself is limited. Although there is a purification air conditioner, in a short period of time, the clean area is in a state of unqualified dust particles.
And in this situation for a long time, it will increase the burden of purifying the air conditioner and shorten the cycle of cleaning the filter and the return air outlet
[0005] In the prior art, there is no related preventive measures for the dust scattered and overflowed when the fluidized dryer is discharged

Embodiment 1

[0019] The structure of the new boiling dryer is as follows: figure 1 shown.

[0020] The new boiling dryer is composed of an air inlet system, a drying body and an exhaust system. Among them, the air intake system (1) consists of a fresh air treatment box (2), an air intake pneumatic valve (3) and an air intake duct (4). The fresh air treatment box (2) has a primary filter (5), a medium Filter (6) and sub-high-efficiency filter (7), if necessary, also can have heater in the fresh air processing box (2); Drying machine body comprises bottom bin (8), feed bin (9) and boiling bin (10) Consists of two sets of exhaust systems, one set is a dry exhaust system (11), including a dry exhaust pneumatic valve (12), a dry exhaust filter (13), a dry exhaust fan (14) and a dry exhaust duct (15) composition; the other is dust removal exhaust system (16), comprises dust removal exhaust air valve (17), dust removal exhaust filter (18), dust removal exhaust fan (19) and dust removal exhaust ...

Embodiment 2

[0040] The structure of the new boiling dryer is as follows: figure 2 shown.

[0041] The new boiling dryer is composed of an air inlet system, a drying body and an exhaust system. Among them, the air intake system (1) consists of a fresh air treatment box (2), an air intake pneumatic valve (3) and an air intake duct (4). The fresh air treatment box (2) has a primary filter (5), a medium filter (6) and sub-high-efficiency filter (7); the drying body comprises a bottom bin (8), a feed bin (9) and a boiling bin (10) to form. A bag filter (21) is arranged in the boiling bin (10).

[0042] The dry exhaust system and the dust removal exhaust system are combined to form an exhaust system, including a dry exhaust duct (15), a bypass pipeline (22), a dry exhaust pneumatic valve (12), a dust removal and exhaust pneumatic valve (17 ), a drying exhaust filter (13) and a drying exhaust fan (14). Add a bypass pipeline (22) with a smaller pipe diameter at both ends of the dry exhaust p...

Abstract

The invention provides a novel fluid bed drier which comprises an air inlet system, a drying machine body and exhaust systems. The novel fluid bed drier is characterized in that the exhaust systems comprise a drying exhaust system and a dust removing exhaust system, and in addition, the drying exhaust system and the dust removing exhaust system run asynchronously in the working state of a dryer. By means of the novel fluid bed drier, the different exhaust systems are used in drying and discharging correspondingly, outer leakage of dust in a boiling bin is effectively prevented in the discharging process, the production environment is protected, the cleanliness requirement of a production area is ensured, the phenomena that outer leakage of dust exists, boiling exhaust is started, and consequently air balance is affected, and damage is caused to room roofs and walls are avoided, burdens of a system purification air conditioner are reduced, the cleaning and replacing times of an air return filtering net and a system filter are reduced, and economic efficiency and environment friendliness are achieved.

Description

technical field [0001] The invention provides a novel fluidized drying device, in particular, a novel fluidized dryer. belongs to the mechanical field. [0002] technical background [0003] The boiling dryer has two working states, one is the spray granulation drying state: the powdery material is put into the closed container of the silo, and due to the action of the hot air flow, the powder is suspended in a fluidized circulation to achieve uniform mixing, and spraying at the same time Enter the mist adhesive to wet the powder in the container, so that the powder condenses into loose small particles. At the same time as granulation, due to the high-efficiency drying of the hot air flow, the water evaporates continuously, and the powder continues to condense. The process is repeated to form Uniform microporous spherical particles, complete mixing, granulation and drying in one container. During the formation of granules, some fine powders will fall off, and some fine powd...
