Step S36 after construction, closes motor I 401, motor IV 507 and lubrication filling pump 508, will be on secondary mixing apparatus Hand throttle 208 reset, stir air operated reversing valve 207, secondary mixing apparatus be moved to cleaning place, is stirred again pneumatic Reversal valve 207, and certain position is arrived into the setting of hand throttle 208, the residue-removing door 404 of U-shaped conveying blender 4 is opened, control is clicked Operation button in system 7 processed, starting jetting machine 8 cleans secondary mixing apparatus, after cleaning, closes high pressure Cleaning machine 8 and residue-removing door 404, reset hand throttle 208 and air operated reversing valve 207, and secondary mixing apparatus carries out transition.
Scene is secondary to mix and stir, if the slump of tank car inner concrete cannot still expire after any of the above-described working method is mixed and stirred II frequency of frequency converter should be arranged according to the slump of concrete in sufficient construction requirement, so that motor II 602 reaches required revolving speed, Additive is through 603 atomized spray of nozzle to concrete surface, and the linear adjustable extent of additive flow is 0-0.75L/min, herein Additive be liquid that original additive and water are matched by a certain percentage, to by the secondary concrete mixed and stirred of additive again into The measurement of row performance indicator after construction, should first close motor II 602 until reaching job specfication requirement.
The productivity of the concrete of different slumps, continous way oscillating mixer 5 is different, I frequency of initial setting up frequency converter For 50HZ, according to stirring and material position situation of the concrete in continous way oscillating mixer 5, then the frequency of frequency converter I is adjusted A certain determining value of the rate between 30-60HZ, while the frequency of corresponding adjustment frequency converter II is a certain true between 15-60HZ Definite value.
In order to detect the performance after the present invention stirs the concrete after tank car transports with certain slump-loss, It is each to the concrete test block that same tank car concrete acquisition mix is forward and backward three and to detect, Testing index include the slump, Divergence, the emptying time of falling bucket and compression strength and corresponding intensity coefficient of dispersion take test block process mixed in strict accordance with country Solidifying soil nature energy examination criteria carries out.Surveyed index result is as follows:
1 two continuous shaking stirring test construction workability comparisons of table
The slump (mm) Divergence (mm) Rewinding emptying time (s)
Before secondary vibration stirring 110 210*200 7.45
After secondary vibration stirring 170 250*240 2.00
To be known by table 1, the slump, divergence of concrete after secondary continuous shaking stirring of the finished product concrete in tank car improve, The emptying time of falling bucket is greatly decreased, and concrete construction workability is significantly improved, and the scene that can greatly reduce adds water construction Probability, and the molding of vibrating of concrete is more conducive under equal conditions, improve the compactness of concrete.
2 two continuous shaking stirring test compression strength comparisons of table
Known by table 2, promotes 10% or so through live secondary agitation concrete crushing strength, tension variance reduces by 30% or more, mixes Solidifying soil property amount is more uniform, effectively increases the durability of engineering and reduces the maintenance cost in later period.
The present invention can be realized function and beneficial effect in claim it can be seen from above specific embodiment Fruit, for those skilled in the art, the details that the present invention is not limited to the above embodiments, without will be in claim Any appended drawing reference is construed as limiting the claims involved.
