Problems solved by technology

If the speed is slow, the drying time will be prolonged, and the oil contained in the oil shale will be decomposed. If the temperature is high, the oil contained in the oil shale will also be decomposed, resulting in a decrease in the oil recovery rate.

Embodiment Construction

[0030] The working principle and connection mode of the porous drum dryer of the present invention are as follows: figure 1 As shown, during the production operation, the solid material enters the hopper 1 through the transport belt, passes through the star feeder 3 and enters the perforated drum 8 of the perforated drum dryer through the introduction pipe 4, and enters the upper and lower parts of the star feeder 3 Each is equipped with a gate valve 2. When the star feeder 3 or the perforated drum 8 fails, the gate valve 2 can be closed for maintenance, which is safe and reliable. Both the material inlet and outlet are provided with a sealing cover 17, the sealing cover 17 is fixed on the box body 5 of the dryer, and the contact part between the sealing cover 17 and the drum 8 is sealed with a sealing ring 9; the outer wall of the drum of the dryer is passed through a rib 23 It is connected with the main shaft 10 of the drum, and the two ends of the main shaft 10 of the drum ...

Abstract

The invention relates to equipment for quickly and efficiently drying a large amount of solid materials. The equipment is characterized in that: a porous roller is arranged in a box body of which the inner wall is coated with a heat preservation material; a plurality of small holes are formed in the roller; and a sieve screen and a guide plate are arranged on the inner wall of the roller. In the drying equipment, gases such as air, nitrogen, steam, fume, gas and the like are as dry hot media according to site conditions, and the drying equipment has the advantages of high heat exchanging intensity, short drying time, high thermal efficiency, relatively compact volume, high sealing performance, high safety, environment friendliness and the like. The equipment is suitable for drying granular solid materials in industrial and agricultural raw materials and products, and is suitable for drying oil shale and coal when the temperature of the drying hot media is below 300 DEG C.

Description

technical field [0001] The invention relates to a device for drying bulk solid materials, which is suitable for drying granular solid materials in industrial and agricultural raw materials and products. Background technique [0002] In industrial production, in order to meet the requirements of use, reduce the moisture content of materials, improve product quality, classify, or protect the environment, it is often necessary to dry some solid materials. At present, the commonly used drying equipment in the industry includes hot air blowing type, baking type, rotary drum type, fluidized bed type, rotary vane type and other drying equipment. Some of these drying equipment have low efficiency and are not suitable for handling bulk materials. Some are bulky and consume a lot of power. For example, although the rotary drum drying equipment can handle bulk materials, it can only rely on the tumbling of the materials in the rotary drum to increase the chance of contact between the ...
