Description

Spray drier with uniform drying Technical Field The utility model relates to the technical field of spray dryers, in particular to a spray dryer with uniform drying. Background The spray drier is a device capable of simultaneously completing drying and granulating, the spray drier consists of a drying tower, a valve, a cover, a connector, an atomizer, a heat inlet pipe, a heater, a blower, an air filter, a connecting pipe and a discharge pipe, when the spray drier is used, a material pipe is fixed with the connector, the discharge pipe is connected with a gas-solid separation system by using a pipeline, then the material is input to the connector by a pressure pump, then small liquid drops are sprayed out by the atomizer, air passes through the air filter, the blower and the heater, so that hot air is sprayed into the drying tower by the heat inlet pipe, and then contacts and dries with the sprayed small liquid drops, the heated small liquid drops evaporate into powder, then the powder of coarse particles falls to the bottom of the inner wall in the drying tower, the fine particles are pumped to the gas-solid separation system together with hot air by the blower through the discharge pipe for dust removal, the powder of the fine particles can be recovered by opening the valve. The inventor finds that when the spray dryer is used in daily work, hot air is blown out from the top of the interior of the drying tower through the air inlet pipe when small liquid drops sprayed out of the atomizer are dried, so that the small liquid drops are difficult to contact with the hot air in the drying process, the drying uniformity is reduced, and further the quality of the materials is likely to be affected easily due to the fact that atomized liquid drops are discharged along with the dried materials. Disclosure of utility model The utility model aims to solve the problems that in the actual use process, when small liquid drops sprayed out of an atomizer are dried, hot air is blown out from the top inside a drying tower through a heat inlet pipe, so that the small liquid drops are difficult to contact with the hot air well in the drying process, the drying uniformity is reduced, and further the quality of the materials is likely to be affected by atomized liquid drops along with the discharge of the dried materials.
