Efficient drying hopper

Abstract

The invention relates to an efficient drying hopper which comprises an inner-layer hopper and an outer-layer hopper. A cylinder is arranged on the upper portion of the inner-layer hopper. A discharging opening in the lower portion of the inner-layer hopper is connected with the bottom of the outer-layer hopper in a welded manner. A connecting frame is arranged at the upper end of the space betweenthe inner-layer hopper and the outer-layer hopper. The two sides of the connecting frame are connected with the inner-layer hopper and the outer-layer hopper correspondingly in a welded manner. A cavity is formed between the inner-layer hopper and the outer-layer hopper. A spiral pipe is arranged in the inner-layer hopper. The upper end and the lower end of the spiral pipe are closed. The outer side face of the spiral pipe and the inner wall of the inner-layer hopper are connected in a welded manner. Multiple through holes are formed in the inner wall of the inner-layer hopper. An inner cavity of the spiral pipe communicates with the cavity through the through holes. Multiple air outlets are formed in the surface of the spiral pipe. An air inlet is arranged on the outer wall of the outer-layer hopper and is connected with an air inlet pipe. The air inlet pipe is connected with an air blower. A heater mounted on the air inlet pipe is arranged at the front end of the air blower. The efficient drying hopper is simple in structure, convenient to manufacture and low in machining and manufacturing cost; through the arrangement of the inner-layer hopper, the outer-layer hopper and the spiral pipe, materials can be evenly dried effectively, and energy can be saved; and therefore the material machining quality is guaranteed, and the drying efficiency is high.

Description

technical field [0001] The invention relates to a hopper, in particular to an efficient drying hopper. Background technique [0002] At present, the feeding device is widely used in industries such as mining, coal, food, chemical industry, medicine and construction. The feeding device mainly includes a hopper and a transmission device, such as a belt conveyor. Among them, the hopper is the main part of the feeding device. Usually, plastic granules need to be dried before they are put into the extruder to be processed into finished products, especially in the high temperature and humid environment in southern my country, more drying is required. The charging container of the existing drying machine includes a hopper and a bucket. The hopper is composed of a side wall, and the side wall forms an accommodating space for loading raw materials. The bottom of the hopper is connected with a drying device. After the drying device is heated, hot air is blown into the hopper by a bl...

Problems solved by technology

However, when the material enters the hopper, the hot air can only dry the bottom of the material. The material is heated unevenly, and the drying effect is poor, which affects the quality of the material.
