Energy-saving double-drum dryer

Abstract

The invention relates to the technical field of drying equipment, and discloses an energy-saving double-drum dryer. The dryer comprises a base plate, wherein a supporting table is fixedly connected tothe upper surface of the base plate, a heat source is fixedly connected to the top surface of the supporting table, a fixing base is fixedly connected to the upper surface of the base plate and located on the right side of the supporting table, an outer drum fixedly sleeves the middle of the top surface of the fixing base, and an inner drum is movably sleeved with an inner cavity of the outer drum. The heat source is placed in the middle of the dryer for heat transfer so that heat received by the materials is the same; meanwhile, fan blades are used for raising the fed materials to increase the heat receiving area of materials; the problems of uneven material drying and low efficiency of the dryer caused by different heat received by the materials in the dryer due to less heat received bythe materials at one end of the dryer are solved, the purpose of evenly drying the materials is achieved, and meanwhile, the drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to an energy-saving double cylinder dryer. Background technique [0002] The double cylinder dryer is a direct type rotary dryer, mainly composed of inner cylinder, outer cylinder, idler roller, wheel belt support device, transmission device, feeding and air intake, discharge and air outlet and other sealing devices. Composition, the double cylinder dryer is mainly used for drying granular materials within a certain humidity and particle size range, such as yellow sand used in the dry powder mortar industry, various specifications of sand used in the foundry industry, blast furnace slag used in the construction cement industry, etc., double cylinder drying The dryer has high thermal efficiency, remarkable energy-saving effect, and has the advantages of high efficiency, energy saving and compact structure. It is widely used in different industries. According to the moisture ...

AI Technical Summary

Problems solved by technology

[0003] When using a double-cylinder dryer to dry materials, the heat source is often placed at one end of the feed port for heat transfer, which will cause the materials at the other end of the dryer to receive less heat, resulting in The heat received by the materials is different, resulting in uneven drying of the materials and low efficiency of the dryer. At the same time, when the dryer is working, a transmission device is often used to rotate the outer cylinder of the dryer. The size of the dryer is large, and the use of a transmission device to drive the dryer requires a large amount of electric energy, resulting in a waste of production costs. In addition, the commonly used double-cylinder dryer is placed horizontally, and the transmission device is placed on the bottom of the dryer. , due to the large volume, the land space is wasted and the maintenance is troublesome. Now we introduce an energy-saving double cylinder dryer
