Description

Building rubbish solid powder and particle material mixing method and equipment used by same

Technical Field

The invention relates to a construction waste treatment method and equipment thereof, in particular to a drum-type stirrer for construction waste solid powder and granules and a treatment method using the equipment.

Background

Building rubbish mixes and can recycle through smashing, stirring, and agitating unit among the prior art is mostly the cylinder of slope, and it is rotatory and the hank cage does not rotate or hank cage rotates and the cylinder does not rotate generally to be the cylinder, and the tooth of stirring cage all is fixed dead. Like this, building rubbish powder and grain material can condense into the mud cubic under humidity is great or under the water spray state, and it is great to roll the height in the cylinder, and the shearing force that the hank cage needs to overcome is also great, and the power consumption is great on the whole, and stirring efficiency is not high.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, achieves the aims of improving the stirring efficiency and reducing the energy consumption by improving the relative operation mode and the internal structure of the stirring cage structure and the roller, and provides a method and equipment for improving the mixing efficiency of building garbage powder and granular materials and reducing the energy consumption.

The technical scheme of the invention is as follows:

a mixing method of solid powder and granular materials of construction waste adopts a drum-type stirring method, a stirring cage which is coaxial with a drum is arranged in the drum, and the drum and the stirring cage in the drum rotate in the same direction and have a rotation speed difference during working; the stirring cage is provided with stirring teeth and an interposed flexible stirring chain.

The rotation speed ratio of the roller to the stirring cage is 1:3-3.5

The utility model provides a building rubbish solid powder granule drum-type agitator, the cylinder slope lies on the back, the high-end opening of cylinder, and be equipped with the dog-house that corresponds above it, bottom portion has the discharge gate, there is the stirring cage with the axle center with the cylinder in the cylinder, cylinder and stirring cage respectively have a motor to drive respectively and can do asynchronous rotation, the outer fringe diameter that the stirring cage is connected out by a logical epaxial is close and is less than the keel frame of warp in the cylinder, alternately set up fixed stirring tooth of multirow and many flexible stirring chains along the cylinder axial on the keel frame.

The cylinder is the toper from high-end to low-end, cylinder low-end bore is less and have the end cover disjunctor with the cylinder, outwards extend along the cylinder axle center on the end cover and support and drive the rotatory transmission shaft of cylinder, this transmission shaft passes through the bearing, the bearing frame bearing is on the board and extends and connect out drive wheel b, the symmetry sets up two at least bearing rollers on the bottom surface board in the high tip outside of cylinder and rolls with the bearing roller, the high-end oral area of cylinder is equipped with the cross supporting beam of connection on the wall of cylinder mouth, the logical axle of agitator cage passes this cross supporting beam center department through the bearing and outwards extends the connection support bearing, bearing frame and drive wheel a, the logical axle other end of agitator cage passes through bearing shaft connection support on the end cover inner wall.

The flexible stirring chain adopts a chain. The flexible stirring chain is adopted, so that the caking of the materials in the mixing process can be broken and untied on the spot, the materials are prevented from rolling in the drum to the left to a large extent, and the purpose of energy conservation is achieved.

More specifically, in order to reduce dust pollution, a water spray device is arranged at the feeding port of the roller.

The stirring cage and the roller rotate in the same direction, and the rotation speed of the stirring cage is higher than that of the roller, so that the rolling stirring efficiency of the powder and the granular materials can be improved, the shearing of the powder and the granular materials by the stirring cage is reduced (the shearing is not useful for mixing), and the energy consumption can be reduced.

Detailed Description

The ratio of the rotational speed of the drum to the rotational speed of the agitator cage is 1: 3.

A building rubbish solid powder granule drum-type agitator, the cylinder 4 is inclined and supine, there are feed inlets 3 at the high end of the cylinder, there are discharge ports 12 at the bottom end, there are mixing cages 6 with the same axle center of cylinder in the cylinder, cylinder and mixing cage have a motor to drive to rotate asynchronously separately, mixing cage 6 is close to and smaller than the skeleton frame passing through in the cylinder by the outer fringe diameter that connects out on a through shaft 5, set up multirow fixed mixing tooth 8 and multiterm flexible stirring chain 7 alternately on the skeleton frame axially along the cylinder; the cylinder is the toper from high-end to low-end, cylinder low-end bore is less and have the end cover 10 with the cylinder disjunctor, outwards extend the support and drive the rotatory transmission shaft of cylinder along the cylinder axle center on the end cover 10, this transmission shaft passes through the bearing, the bearing frame bearing is on the board and extends and connect out drive wheel b11, the symmetry sets up two at least bearing rollers 14 on the board in the high-end outside of cylinder and rolls with the bearing cylinder, the high-end oral area of cylinder is equipped with the cross supporting beam of connection on the wall of cylinder mouth, the logical axle 5 of agitator cage passes this cross supporting beam center department through the bearing and outwards extends the connection support bearing, bearing frame and drive wheel a2, the logical axle other end of agitator cage passes through bearing shaft connection support on the end cover inner wall.

The flexible stirring chain 7 adopts an industrial chain. The flexible stirring chain is adopted, so that the caking of the materials in the mixing process can be broken and loosened on the spot, the materials are prevented from rolling in a roller to a large extent, and the purpose of energy conservation is achieved. More specifically, in order to reduce dust pollution, a water spray device is arranged at the feeding port of the roller. The stirring cage and the roller rotate in the same direction, and the rotation speed of the stirring cage is higher than that of the roller, so that the rolling stirring efficiency of the powder and the granular materials can be improved, the shearing of the powder and the granular materials by the stirring cage is reduced (the shearing is not useful for mixing), and the energy consumption can be reduced.
