Description
Technical field
The invention belongs to construction engineering technical field, and in particular to a kind of cleaning method of concrete mixer.
Background technology
Surrounding city or the construction site in urban district, including municipal administration, Fang Jian, road and bridge etc., the overwhelming majority are mixed using commodity
Solidifying soil, fraction are independently stirred at the construction field (site) using mortar or the general of concrete using concrete mixer.But one
A little roads inconvenience, transport are difficult, haul distance mountain area farther out or other etc. place, especially road and bridge construction scene, using mixed
It is many that solidifying native mixer carries out also having for concrete stirring.Conventional concrete mixer cleaning method is：Using concrete
Mixer pours into 10min~15min in tank body with water and stone after stopping work and cleaned, then water and stone are cleared out；Operator
When member cleans as that must enter in tank body, in addition to cutting off the electricity supply and unloading fuse, switch-box must also be locked；If cleaning concrete
When mixer finds that inner wall of rotary drum has solid, the method for forbidding to be beaten with sledgehammer removes the coagulation accumulated in concrete mixer
Soil, can only slowly it be removed with chisel；Concrete mixer after hours using water cleaning mixer roller and by water pump,
Water tank, water pipe internal water accumulation are put only, in order to avoid freezing, there is following shortcoming for method of the tradition to tank body cleaning：1. operation is tired
Difficulty, cleaning process is cumbersome, and cleaning efficiency is relatively low；2. cleaning method lacks scientific basis；3. intensity of workers is big, safety
It is not easy to ensure；4. cleaning is not abundant enough, or mixer is damaged in cleaning process.
Therefore, a kind of method reasonable, reliability height novel in design is nowadays lacked, can be effectively to mixer tank interior
The method cleaned, prerinse is carried out to tank interior by wiper mechanism, can be residual by a large amount of concrete of tank interior
Stay and rinse out in advance, and a large amount of concrete washed are gone out into tank body, avoid when a large amount of concrete influence formally to clean
Effect；By the way that during formal cleaning, hydraulic pressure is arranged into p1, p1 span is 1000bar~1300bar, and
Hydraulic pressure is maintained at p1 persistently cleaning 20min~25min is rotated forward to mixer, sufficiently can washed away the concrete in tank body
And be dissolved in water, and the water with concrete carries out continuous erosion in rotary course to tank interior, cleaning is more thorough.
The content of the invention
Stirred in view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that providing a kind of concrete

mixer rotating are combined cleaning tank body：Control the high-pressure hydraulic pump to make hydraulic pressure adjust to p3, control to stir Mix machine and rotate forward 10~15 circles, then control the circle of mixer reversion 5~10, p3 is more than p2, and p3 is equal to 1150bar~1400bar；Step 304, step 301 is repeated several times to step 303, until the tank body is cleaned up；Step 4: cleaning device is removed：After completing to the cleaning of mixer, control the high-pressure hydraulic pump to close, control mixer Reversion empties the water in the tank body, is then switched off mixer, the cleaning device is removed.
