Description

Centrifugal Spray Dryer

technical field

The utility model relates to a centrifugal spray dryer.

Background technique

The spray dryer in the prior art draws hot air through the induced draft fan, pumps in the wet material through the material pump, and then sprays it into the drying cylinder from the atomizing nozzle for drying. Due to the limited atomization effect of the ordinary atomizing nozzle, the material It is very easy to dry incompletely and stick to the wall.

Contents of the invention

The purpose of the utility model is to overcome the defects in the prior art and provide a centrifugal spray dryer, which can centrifugally atomize the wet material through a centrifugal atomizer, and the atomization effect is good, so that the material is completely dried without sticking to the wall Phenomenon.

In order to achieve the above object, the technical solution of the utility model is to provide a centrifugal spray dryer, which includes a frame, a drying cylinder fixed on the frame, an air distributor and a centrifugal spray dryer are arranged on the top of the drying cylinder. Sprayer, the air distributor is connected with an air supply pipeline, the air supply pipeline is connected with a heater, the centrifugal sprayer is connected with the feed tank through a feed pipeline, a material pump is arranged on the feed pipeline, and the drying cylinder The bottom of the bottom is connected with a dry material delivery pipe, the dry material delivery pipe is connected with a cyclone separator, the material outlet of the cyclone separator is connected with a dry material tank, and the air outlet of the cyclone separator is connected with a dust removal tank, so The top of the dust removal pipe is provided with a dust remover, and the dust removal tank is connected with an induced draft fan through an exhaust pipe.

A further improvement is: a muffler is provided at the connection between the exhaust duct and the induced draft fan.

A further improvement is: the lower parts of the drying cylinder, the material tank and the dust removal tank are all conical, and the lower parts of the material tank and the dust removal tank are connected with discharge valves.

A further improvement is: support rods are respectively provided on both sides of the frame and the lower part of the drying cylinder.

The advantages and beneficial effects of the utility model are: after the air is heated by the heater, it enters the air distributor on the top of the drying tower through the induced draft fan. Sent to the centrifugal sprayer at the top of the drying tower, the feed liquid is sprayed into extremely small mist droplets, which greatly increases the contact area between the feed liquid and hot air, evaporates the water quickly, and dries to a dry product in a very short time.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figure 1, a centrifugal spray dryer includes a frame 1, a drying cylinder 2 fixedly arranged on the frame 1, the top of the drying cylinder 2 is provided with an air distributor and a centrifugal sprayer, the The air distributor is connected with an air supply pipe 3, the air supply pipe 3 is connected with a heater 4, the centrifugal sprayer is connected with the feed tank through a feed pipe, the feed pipe is provided with a material pump, and the drying cylinder The bottom is connected with a dry material delivery pipe, the dry material delivery pipe is connected with the cyclone separator 5, the material outlet of the cyclone separator 5 is connected with a dry material tank 6, and the air outlet of the cyclone separator 5 is connected with a dust collector Tank 7, the top of the dust removal pipe is provided with a dust collector 8, and the dust removal tank 7 is connected with the induced draft fan 11 through the exhaust pipe 9.

Working principle: After the air is heated by the heater 4, it enters the air distributor on the top of the drying tower through the induced draft fan 11. After passing through the air distributor, the hot air enters the drying tower evenly, and the material pump sends the material liquid to the top of the drying tower at the same time. With the advanced centrifugal sprayer, the material liquid is sprayed into very small mist droplets, which greatly increases the contact area between the material liquid and hot air, the water evaporates rapidly, and dries to a dry product in a very short time.

In order to reduce noise, a preferred implementation in this embodiment is that a muffler 10 is provided at the connection between the exhaust duct 9 and the induced draft fan 11 .

A preferred implementation in this embodiment is that the lower parts of the drying cylinder 2 , the material tank and the dust removal tank 7 are all conical, and the lower parts of the material tank and the dust removal tank 7 are connected with discharge valves.

A preferred implementation manner in this embodiment is that the two sides of the lower part of the frame 1 and the drying cylinder 2 are respectively provided with support rods.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
