Technical field

The utility model is related to the processing equipment of expanded perlite, more particularly to a kind of the U-shaped of expanded perlite of mixing and stirring is mixed And equipment.

Background technology

Expanded perlite is a kind of natural acidic nature of glass slag, nonmetallic minerals, including perlite, pitchstone and Obsidian, three are crystal water content difference.Due to its rapid spatial expansion 4~30 under 1000~1300 DEG C of hot conditions Times, therefore it is referred to as expanded perlite.

The construction industry of attention with to(for) fire safety, advantage of the expanded perlite in terms of building heat preservation are gradually shown Carry out because expanded perlite belong to thermally expand after the rigidity foaming microcellular structure that generates, structure organization is fragile, be squeezed or After friction particle will breaking and Dusting, volume contraction and cannot restore.

It includes superfine silicon dioxide, binding material, powder curing agent, chimney to mix and stir the filler used when expanded perlite Ash, industrial aluminum sulphate etc..It can just be further used as material after filler and expanded perlite uniform mixing and go construction and installation.

The expanded perlite mixing plant that energy-saving heat preserving industry generally uses at present, when stirring, are easily destroyed expanded perlite Particle, compression volume, while will produce " rice dumpling formula condense ball " stirs non-uniform problem.

Utility model content

The purpose of this utility model is to provide a kind of U-shaped mixing apparatus mixing and stirring expanded perlite, its advantage is that batch mixing It stirs evenly, gently.

The above-mentioned technical purpose of the utility model technical scheme is that：One kind mixing and stirring expanded pearlite The U-shaped mixing apparatus of rock, including sequentially connected feeding mechanism, mix and stir mechanism and discharging mechanism；Feeding mechanism includes for expansion The feeding warehouse one of perlite charging, the feeding warehouse two fed for filler；It includes the U-shaped teeter chamber in section to mix and stir mechanism, stirring Room is connected to feeding warehouse one and feeding warehouse two respectively, and propulsion tube is undertaken between feeding warehouse two and teeter chamber, is equipped in propulsion tube Augering screw, augering screw are connected with propulsion electric machine；Agitating shaft is rotatably connected in teeter chamber along its length, on agitating shaft Stirring shovel equipped with several sheets, the axial line angulation of plane and agitating shaft is 30 ° ~ 45 ° where stirring shovel, outside teeter chamber Equipped with the stirring motor for driving agitating shaft rotation；Discharging mechanism includes discharging band and drives the discharging machine of discharging V belt translation, One end bottom side of teeter chamber is equipped with the blow tank being bonded with discharging band；Propulsion electric machine, stirring motor, discharging machine are that rotating speed can Tune type motor.

Through the above technical solutions, teeter chamber is U-shaped structure, the arc transiting surface of inner wall is more gentle, and batch mixing is being mixed Smooth movement is realized in the process, therefore batch mixing is not easy to smash in progradation；It is further stirred for shovel and uses 30 degree to 45 The design of degree, the angle can reduce stirring shovel and the impact pulse of batch mixing while ensureing feed speed, realize speed and The balance of integrity degree controls；Meanwhile propulsion electric machine, stirring motor, discharging machine when controlling rotating speed that is, controlling whole The feeding of body material and output speed, avoid local material and are squeezed in teeter chamber and form lump so that whole inputs, is defeated Go out and keep stablizing, the quality after batch mixing output is preferable, and the uniformity is higher, has higher economic benefit.
