A rotary drum dryer for flexible items

Abstract

The invention discloses a rotary drum dryer for flexible articles. The rotary drum dryer for flexible articles comprises a fixed rack and a rotary rack which is arranged on the upper side of the fixed rack, wherein the front part of the rotary rack is hinged to the fixed rack and the rear part of the rotary rack can swing up and down; and a rotary drum device, a power device which drives the rotary drum device and an exhaust fan are arranged on the rotary rack. In order to overcome the shortcomings in the prior art, the invention provides the special rotary drum dryer for flexible articles such as cotton products and rubber. As hot wind in adrying oven cavity flows in a diffused manner and is uniformly distributed, the rotary drum dryer ensures that materials can be uniformly and quickly dried, so that the drying efficiency is improved and the heat utilization rate of the rotary drum dryer is high.

Description

technical field [0001] The invention relates to a rotary drum dryer suitable for fabric products such as cotton, hemp, chemical fiber and wool and rubber flexible products. Background technique [0002] After the production and washing and drying of flexible items such as cotton products and rubber, they must be dried and cooled before they can be packaged. At present, the equipment used for drying is the traditional drum clothes dryer. This kind of dryer has an iron shell, and there is a drum for clothes inside. There are many holes on the drum, and the hot air enters the dryer from the top of the machine. Clothing machine, most of the hot air passes through the gap between the casing and the drum, and a small part of the hot air enters the inside of the drum through the holes on the drum to dry items. Once the holes on the drum are blocked, the hot air entering the drum will be greatly reduced, resulting in large temperature fluctuations in the drum, serious heat leakage,...

Problems solved by technology

At present, the equipment used for drying is the traditional rotary drum clothes dryer. This kind of dryer has an iron shell, and there is a drum for clothes inside. There are many holes on the drum, and the hot air enters the dryer from the top of the machine. Clothing machine, most of the hot air passes through the gap between the shell and the drum, and a small part of the hot air enters the inside of the drum through the holes on the drum to dry items. Once the holes on the drum are blocked, the hot air entering the drum will be greatly reduced, resulting in large temperature fluctuations in the drum, serious heat leakage, and low heating efficiency, resulting in low production efficiency and large energy waste

In particular, the temperature range in the drum cavity is large, and the operation process is slightly improper. If the temperature is too high or the time is too long, the items that need to be dried at low temperature will be damaged.

In the production of rubber gloves and balloons, this kind of dryer is used as the equipment for final drying products, which often causes defects such as product quality fluctuations and high reject rates.
