Description

Internal heating type drum dryer capable of adjusting air

Technical Field

The utility model relates to a drum-type drying-machine field specifically is an interior hot type cylinder drying-machine of adjustable wind.

Background

Drum-type drying-machine universal application in industrial production, current drum-type drying-machine generally only has an outer cylinder, and outer cylinder inner wall is equipped with the baffle, has following problem in the in-service use: 1. when the dryer rolls, materials fall from the top of the roller and impact the bottom of the roller, the impact force is large, the roller is easy to wear after a long time, and the service life of the dryer is shortened; 2. the material is heated and dried through the high-temperature flue gas in the roller, the heat exchange time is shortened when the flow velocity of the flue gas is too fast, the heat exchange effect is reduced, and the flow of the flue gas cannot be adjusted in the roller.

Disclosure of Invention

The utility model aims at solving the problem of the existing dryer, and providing an internal heating type drum dryer with adjustable air.

The utility model has the following concrete scheme: an internal heating type roller dryer capable of adjusting air comprises a roller shell, wherein one end of the roller shell is provided with a feed inlet, the other end of the roller shell is provided with a discharge outlet, a guide chute is arranged at the feed inlet, an overflowing gap is arranged between the feed inlet and the guide chute and used for introducing high-temperature flue gas, the inner wall of the roller shell is provided with a plurality of partition plates, an inner barrel is arranged at the center of the inner part of the roller shell, a plurality of supports are arranged between the inner barrel and the roller shell and used for fixing the inner barrel, a region between the inner barrel and the roller shell is used for placing materials, an adjustable air door is arranged at one end of the inner barrel, which is close to the discharge outlet, the adjustable air door comprises a fixed air door and a movable air door, a plurality of air holes are respectively arranged on the fixed air door and the movable air door, the air holes of the movable air door are in one-to-one correspondence with the air holes of the fixed air door, and a locking bolt is arranged at the center of the movable air door, the locking bolt is used for fixing the position of the movable air door.

Be equipped with the round between fixed air door and the inner tube and leak the material clearance, leak the width in material clearance and be greater than the diameter of material, fixed air door passes through a plurality of extension boards and inner tube fixed connection.

Baffle one end is equipped with the arc hopper, and the orientation of arc hopper is the same with cylinder direction of rotation.

The working principle of the utility model is as follows: the material gets into in the drum shell, along with the cylinder is rotatory, the flitch of inner tube outer wall shovels a part of material and gathers, fall back drum shell again after the rotatory round of material that is shoveled, high temperature flue gas divide into two parts after getting into in the drum shell, partly regional flow through between inner tube and urceolus, this part flue gas mainly with material convection heat transfer, another part passes from the inner tube is inside, this part flue gas mainly heats the inner tube, pass through heat-conduction heat transfer through inner tube and material, adjust the size of wind hole flow area through the angle of adjusting movable air door, realize adjusting the flow of flue gas according to actual conditions, improve heat transfer effect.

The utility model discloses following beneficial effect has: 1. the arrangement of the inner barrel reduces the falling height of the materials and reduces the impact force on the equipment, thereby reducing the abrasion and prolonging the service life; 2. the adjustable air door is arranged, so that the flue gas flow of the inner barrel can be adjusted according to actual conditions, and the heat exchange effect is improved.
