Description

A kind of coagulation mixing plant
Technical field
The invention belongs to concrete manufacturing technology fields, more particularly, to a kind of coagulation mixing plant.
Background technology
Self-discharge concrete mixer also known as freely falls formula blender, wherein and mixing drum is rotated with speed appropriate, Material is fixed in the mix drum of mix blade in it by mix also just with constantly turning round, and blade is constantly by material Material be promoted to certain height after, material is left under Gravitative Loads under blade free falling, so repeatedly to material into Row stirring, to ensure the uniformity of material mix.
But existing mixing plant usually only outer barrel rotates, and rotating speed is slower, to material from the speed that falls compared with Slowly, the mixed effect and between cement and unclassified stores is poor, and concrete performance obtained is poor.And if by improving turning for outer barrel Speed improves mixed effect, then driving motor needs to use prodigious power, energy consumption big.
Invention content
The present invention for overcome the deficiencies in the prior art, provides a kind of concrete and is uniformly mixed, saves the coagulation of energy consumption and stir Mixing equipment.
To achieve the goals above, the present invention uses following technical scheme:A kind of coagulation mixing plant, including rack, can Rollably it is set to the cylinder in rack, set on rotatable agitating device and driving part on cylinder;The stirring dress Set the agitating shaft including being at least partly pierced by the cylinder and the agitating paddle on agitating shaft;The driving part includes driving Part coordinates with the actuator for driving the first transmission component of the agitating shaft rotation and coordinating for driving with the actuator Second transmission component of the barrel body rotation.Pass through the setting of the first transmission component and the second transmission component in the present invention so that In whipping process, cylinder and agitating shaft can rotate, and the direction of the two rotation is on the contrary, to which the material in cylinder exists During falling, it will also hit by the reversed agitation of agitating shaft and with agitating shaft, so that mixed between each material It closes uniformly, concrete performance obtained is good;And cylinder and agitating shaft rotation, the work(of actuator can be driven by an actuator Rate can reach 2 times of mixed effect of traditional mixing plant in the case where maintaining conventional power, to effectively reduce pair In the consumption of electric energy, energy conservation and environmental protection is realized.
Further, first transmission component includes the driving link being connected with the actuator, is driven with the driving link The driving member of connection and match driven member with the driving member;By the cooperation of driving member and driven member, realize actuator to cylinder The driving of body, for relatively direct driving, the power of actuator can be arranged smaller, and actuator is hardly damaged, service life It is long.
Further, the driven member is the circle driven tooth being fixedly arranged on the barrel outer surface;Pass through the engagement of tooth It realizes transmission, is not only simple in structure and coordinates stabilization, failure rate is low, and maintenance rate is low.
Further, the driving member includes the belt pulley being connected with the driving link by belt and same with the belt pulley The gear of axis setting, the gear are meshed with the driven tooth.
Further, second transmission component includes being coaxially disposed the first driving member with the gear, being stirred set on described Mix the second driving member and third driving member on axis;When gear rotates, the first driving member can be synchronized and be rotated, to driving the Two driving members rotate and then drive agitating shaft rotation, and drive mechanism is simple, and performance is stable and convenient for assembly.
Further, first driving member is transmission gear, and second driving member is outside the agitating shaft One circle sliding tooth, the third driving member are synchronous belt;Pass through the mutual cooperation of synchronous belt, gear and sliding tooth so that transmission When gear rotates, agitating shaft can be driven to be rotate in same direction with it;And cylinder is coordinated in fact with gear by the gear ring on outer surface It now rotates, to which the steering of cylinder is opposite with gear, to realize rotating backward for cylinder and agitating shaft, realization is good Good mixed effect.
Further, the agitating shaft is equipped with air ejection member and the air feed part for conveying gas to the air ejection member Part;By the setting of air ejection member, agitating shaft can during stirring outside jet, so as to occur in whipping process The material of caking is broken up so that the case where mixing of material is more uniformly distributed, is not in caking ensures last obtained mixed Solidifying soil property amount is high, and material mixture homogeneity is high.
Further, the air inlet component includes the intake section being connected with first gas distribution channel and the intake section Inlet suction port, air inlet pipe fitting and the gas generator being connected with the air inlet pipe fitting being rotatably connected;Inlet suction port and intake section Rotatably to coordinate, to which the rotation of cylinder and agitating shaft does not interfere with inlet suction port, ensure that air inlet pipe fitting is not in The case where following agitating shaft to rotate and wind, is less prone to failure;And by by air inlet component be divided into inlet suction port and Air inlet pipe fitting ensures that abrasion occurs over just between inlet suction port and agitating shaft, can be individually to air inlet connecting when inlet suction port is worn Head is replaced, and without entire air inlet component is needed to change, the service life of equipment entirety is long, and maintenance cost is low.
Further, the inlet suction port is equipped with and the matched sealing structure of air inlet pipe fitting, the seal member Include the cage portion on the inlet suction port and multiple sealing elements in cage portion;Cage portion can effectively compress sealing element and make Good sealing is realized between air inlet pipe fitting and inlet suction port, will not be leaked being used for a long time;And the appearance in cage portion It is always compression fit between face and intake section inner wall, sealing effect is good.
Further, the forming method in the cage portion is as follows:a:It cracks:It is spaced on the part surface of the inlet suction port Uniformly open up multiple gaps;b:Punch forming:Punching press is carried out to inlet suction port by press so that seam is opened up on inlet suction port The outside distending in position of gap forms the cage portion;There are multiple strip pieces in cage portion, opening is formed between adjacent bar part Slot, the sealing element are filled in by the open slot to the cage portion;It is molded using above-mentioned molding mode, it is easy to operate, Shaping efficiency is high;By cracking and punching operation, ensure that cage portion straight forming on inlet suction port obtains, it is easy to operate, and protect When having demonstrate,proved later stage inlet suction port and being connected with intake section, excellent sealing between the two.
In conclusion the present invention has the following advantages:Cylinder and agitating shaft is driven to rotate backward by same actuator, no Energy consumption is only saved, and can also be achieved good mixing effect, is uniformly mixed between material, concrete performance obtained is good.
