Embodiment Construction

[0024] Examples of vertical material tumble dryers, such as Figure 1-5 As shown, the vertical material tumbling dryer includes two layers of drying units arranged coaxially from the outside to the inside, and each layer of drying units includes an outer cylinder and an inner cylinder. For the distinction of dry units, the outer and inner cylinders of the outer drying unit are called the outer outer cylinder 11 and the outer inner cylinder 12, and the outer and inner cylinders of the inner drying unit are called the inner outer cylinder Body 13, inner cylinder 14. In addition, the top and bottom of the dryer are respectively provided with air-introducing ducts 15, which are used to introduce hot air into the dryer, and the middle part of the dryer is provided with waste gas ducts 16, the air-introducing ducts and the exhaust air ducts They are all composed of air bags, and the exhaust gas pipeline 16 is used to centrally collect the exhaust gas in the dryer and discharge it u...

Abstract

The invention relates to the field of material dryers, in particular to a vertical material rolling dryer which comprises more than two drying units sleeved together in a layered mode, wherein each of the drying units comprises an outer cylinder and an inner cylinder, one side of the outer cylinder is provided with an outer air flow channel, the inner cylinder is provided with an inner air flow channel, a material channel is defined by the inner cylinder and the outer cylinder, more than two partition plates are distributed in the material channel of each of the drying units around the axis of the inner cylinder, at least one material guide structure for guiding dried materials to flow in a rolling mode is arranged between the upper end and the lower end of each of the partition plates, the inner air flow channel and the outer air flow channel of each of the drying units are communicated with the material channel, one of the inner air flow channel and the outer air flow channel is the hot air channel, and the other is the waste gas channel. The dryer can greatly increase the utilization rate of heat sources and quicken the speed of materials fed into the material channels. Therefore, production efficiency of the vertical drier is increased.

Description

technical field [0001] The invention relates to the field of material dryers, in particular to a vertical material tumbling dryer. Background technique [0002] In the production fields of building materials, metallurgy, chemical industry, printing, briquette, etc., it is often necessary to dry materials with a certain particle size. Vertical dryers are commonly used drying equipment in the above-mentioned production fields. The continuous improvement of energy and efficiency requirements has also been developed rapidly. [0003] The gravity dryer disclosed in the Chinese patent application with the publication number CN101017054A is one of the common vertical dryers. The retaining ring, the distributing cone on the top of the retaining ring, and the lifting plate on the inner wall of the cylinder, among which a hot air channel is formed in the retaining ring, and a The material channel, the cylinder body is provided with a waste gas outlet, and the hot air generated in th...
