Description
Technical field
The present patent application belongs to the technical field of concrete batch plant, specifically discloses a kind of steam-heated concrete
Agitating device.
Background technology
Concrete is widely used in the construction projects such as China's industry, agricultural, traffic, national defence, water conservancy, municipal administration, demand
Constantly increasing.In concrete whipping process, generally require to heat concrete to reach optimal whipping temp.And
Heater in existing concrete batch plant is electric calorifie installation mostly, and these electric calorifie installations can not uniformly add to concrete
Heat, cause a part of temperature height of concrete, a part of temperature is low, and this can have adverse effect on to the mixing effect of concrete.
The content of the invention
It is an object of the invention to provide a kind of steam-heated concrete central mix plant, to solve existing agitating device
Heat the problem of uneven.
In order to achieve the above object, base case of the invention is：Steam-heated concrete central mix plant, including stirring
Bucket and motor, are provided with toroidal cavity in the bucket wall of the agitator, and toroidal cavity is provided with air inlet and gas outlet, on agitator
Motor slot is additionally provided with, motor slot is extended to inside agitator, and motor is arranged in motor slot；It is additionally provided with and is sequentially connected in agitator
Some agitators, the agitator includes rotating shaft, paddle and Hooks coupling universal coupling, the output end of the motor with wherein one
Rotating shaft connects, and the one end of rotating shaft away from motor is connected with Hooks coupling universal coupling, the one end of Hooks coupling universal coupling away from rotating shaft with it is adjacent
The rotating shaft of agitator is connected, and paddle is arranged in rotating shaft；Hollow support bar, and rotating shaft and support are equipped with every rotating shaft
Bar is rotatablely connected, and one end of support bar is fixed on agitator and connected with toroidal cavity, and the other end of support bar is positioned at stirring
In bucket, and the end that any two support bars are located in agitator is interconnected.
The operation principle of this base case is：High-temperature steam is passed through from the air inlet of toroidal cavity, high-temperature steam enters
After entering toroidal cavity, it can transfer heat to inside agitator, concrete is heated.Simultaneously as support bar and ring
Shape cavity connects, and one end in each support bar in agitator connects with same one end of another support bar, so high
Warm steam will not be entered in agitator from support bar, and high-temperature steam flows in support bar and support bar can also be heated,
Support bar can heats to the concrete inside agitator.Start motor, axis of rotation, while rotating shaft and drive Hooks coupling universal coupling
One end rotate, the other end of Hooks coupling universal coupling also can concomitant rotation.Because Hooks coupling universal coupling can change the direction of rotation, institute
Different with the rotation direction of each rotating shaft, the paddle in rotating shaft can just be carried out to the concrete in agitator from different directions
Stirring.
The beneficial effect of this base case is：1. high-temperature steam can be by toroidal cavity, to the side of whole agitator
Wall is heated, and heating effect is good.Meanwhile support bar can heat inside agitator to concrete, further improve
The efficiency of heating surface so that concrete homogeneous heating.2. in this programme, the rotation direction of each paddle is different, so stirring
Leaf can be stirred to concrete from different directions, be sufficiently mixed concrete.
Preferred scheme one：Based on scheme it is preferred, the motor slot is provided with heat insulation layer.Steam can incite somebody to action in heating
To in motor slot, the temperature of motor slot is too high to be impacted to motor heat transfer, there is certain potential safety hazard.And use this
Scheme can then avoid the situation.
Preferred scheme two：Based on scheme it is preferred, the steam-heated concrete central mix plant also include sealing
Case, the Hooks coupling universal coupling are arranged in seal box, and seal box is provided with the through hole passed through for rotating shaft.If by Hooks coupling universal coupling
In agitator, then concrete can block Hooks coupling universal coupling, cause Hooks coupling universal coupling not rotate.Using this programme,
Hooks coupling universal coupling is located in seal box, so concrete can not contact with Hooks coupling universal coupling.Lead to simultaneously as seal box is provided with
Hole, so rotating shaft can be connected through through hole with Hooks coupling universal coupling.
Preferred scheme three：Preferably two it is preferred, the through hole is provided with sealing ring.It can be entered using this programme
One step prevents concrete from entering in seal box.
Preferred scheme four：Based on scheme it is preferred, be additionally provided with heat-insulation layer on the outer wall of the agitator.Using we
Case can reduce the speed of heat losses, improve the efficiency of heating.
Preferred scheme five：Based on scheme it is preferred, the paddle is helical blade.Using other blades, blade
Angle can be formed between rotating shaft, concrete is easily trapped in these corners, causes blade can not be carried out to these concrete
Stirring.And this programme is used, it is curved surface between blade and rotating shaft, the above situation will not occurs.
Brief description of the drawings
Fig. 1 is the structural representation of the steam-heated concrete central mix plant of embodiment；
Fig. 2 is the structural representation of rotating shaft.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：It is agitator 1, toroidal cavity 2, air inlet 3, gas outlet 4, rotating shaft 5, close
Joint sealing 6, motor 7, support bar 8, helical blade 9.
