Description

Technical Field

[0001] The utility model relates to the technical field of drying cylinders, in particular to a rotary sand and gravel drying cylinder. Background Art

[0002] After sand and gravel are mined, they need to undergo a series of treatments, among which the rotary drying drum is a more common drying equipment for sand and gravel.

[0003] In the prior art, a Chinese patent with a publication number of CN 218523872 U discloses a rotary sand and gravel drying cylinder, which adopts the scheme of "including a drying outer cylinder, a drying inner liner is clamped on the inner wall of the drying outer cylinder, and the two ends of the drying inner liner are rotatably connected to the two sides of the inner wall of the drying outer cylinder respectively, a connecting shaft is fixedly provided at the middle position of one side of the drying inner liner, a through groove is opened on one side of the outer wall of the drying inner liner, a heating plate is clamped on one side of the inner wall of the drying outer cylinder, and a sealing cover is clamped on the inner wall of the through groove". In this scheme, starting the motor makes the connecting shaft rotate with the drying inner liner inside the drying outer cylinder, and at this time the drying inner liner rotates while the drying outer cylinder remains stationary, and at the same time starting the heating plate makes the outer wall of the drying inner liner evenly heated, thereby drying the wet sand and gravel inside, and does not directly contact the drying outer cylinder and the heating plate to prevent damage to the device, and the through groove area is closed by bolts and a sealing cover to prevent the sand and gravel from flying out, thereby improving the practicality of the device.

[0004] However, the above scheme still has some shortcomings. For example, in actual use, the rotary drying cylinder needs to add a certain amount of sand and gravel into the drying cylinder when it is turned off and then dry it. After the drying is turned off, it needs to be discharged when the machine is turned off. The operation of the whole process is relatively cumbersome. When large quantities of sand and gravel need to be dried, the drying efficiency is low. That is, the technical scheme proposed by the above patent technology has the defect that large quantities of sand and gravel cannot be dried continuously.

[0005] In view of this, the utility model proposes a rotary sand and gravel drying cylinder. Utility Model Content
