Powdery material drying equipment with dehumidifying device

Abstract

The invention provides powdery material drying equipment with a dehumidifying device. The powdery material drying equipment comprises a tank body and an upper cover, wherein the inner part of the tank body is provided with a drying cavity; a feeding device is arranged on the upper cover; the feeding device consists of a feeding tank, a pulverizing motor, a pulverizing rotating shaft, a rotating blade and a fixed blade; a stirring device and a circulating lifting device are arranged in the drying cavity; the stirring device consists of a second motor, a stirring shaft and a stirring blade; the circulating lifting device consists of a first motor, a lifting rotating shaft and a spiral lifting blade; a microwave heater is embedded in the tank body; the dehumidifying device is arranged on the side wall of the top of the tank body; and the dehumidifying device consists of a dehumidifying pipe, a filtering tank and a dehumidifier. By carrying out crushing treatment on blocky materials through the feeding device, the improvement of material drying quality is facilitated, and the drying speed is accelerated; heat transferring is facilitated through the stirring device; and the circulating stirring of the materials is realized through the circulating lifting device, and the efficient drying of the materials is facilitated.

Description

Technical field [0001] The invention relates to a drying machine, in particular to a powder material drying equipment with a dehumidifying device. Background technique [0002] After calcium oxide, calcium carbonate, calcium hydroxide and other calcium compounds are produced, they usually need to be dried. The existing powder drying equipment is usually air drying equipment and steam drying equipment. Among them, airflow drying equipment is not suitable for batch drying operations; steam drying equipment has poor drying uniformity and is not suitable for mass drying. [0003] Application No. 201620124106.7 discloses a powder drying device, including a drying cylinder, the top side of the drying cylinder is provided with a feed port, and the bottom side of the drying cylinder is provided with a discharge port; the cylinder wall below the feed port A microwave heater is installed on the inside, and a plurality of temperature sensors are evenly installed on the inside of the barrel ...

AI Technical Summary

Problems solved by technology

[0004] In this patent, a stirrer is used to stir the materials, but the structure of the stirrer is single, and there are easy to stir dead angles in the drying cylinder, and the materials cannot be dried evenly, which affects the quality of the dried materials; the materials are easy to agglomerate before drying, and in this patent In addition, there is a crushing device, so that the agglomerated materials will not be dried uniformly; the moisture generated during the drying process is accumulated in the drying cylinder and cannot be discharged quickly, which affects the drying efficiency
