Problems solved by technology

[0004] In general mud recovery, the muddy water is mixed with cement to make new concrete, but in order to clean the mixing sink, more water will be used, resulting in low mud concentration in the sedimentation tank, so it is not reused less slurry, resulting in a low recycling rate of cement slurry

Embodiment

[0045] Example: a mixer truck washing water classification and recovery device, such as figure 1 As shown, it includes a receiving tank 101 , a sand and gravel separator 102 , a conveyor belt 103 , a sedimentation tank 104 , a mixing bucket 200 and a quantitative mixing bucket 300 . The water for cleaning the mixer truck is discharged into the receiving tank 101, and the water flows from the receiving tank 101 into the sand and gravel separator 102, and the sand and gravel separator 102 separates the aggregate and the cement slurry. The aggregate is transported to the conveyor belt 103 , and the cement slurry is transported to the sedimentation tank 104 . After precipitation, the cement slurry with high concentration at the bottom is transported into the mixing bucket 200, and the mixing bucket 200 is used to continuously stir the cement slurry to prevent the cement from coagulating. It is necessary to use cement slurry to transport the cement slurry at the bottom of the mixin...

Embodiment 2

[0066] Embodiment 2: a kind of washing water classification and recovery device for mixer truck, the difference from Embodiment 1 is: the cross-section in the width direction of the single blade 233 located at both ends of the mixing shaft 229 is inclined, and the single blade located at the center of the mixing shaft 229 The cross section in the width direction of the 233 is vertically arranged, the lower surface of the single blade 233 located at the uppermost is facing the rotation direction, and the upper surface of the single blade 233 located at the bottom is facing the rotation direction. The lower single blade 233 makes the water at the bottom of the barrel 201 flow upward, and the upper blade makes the water at the upper side of the barrel 201 flow downward, so that the water flow between the uppermost single blade 233 and the lowermost single blade 233 produces convection. , which further increases the stirring effect, and the convection effect of the water above the ...

Abstract

The invention discloses a cleaning water classification and recovery device for a mixer truck, which belongs to the field of concrete recovery. The water outlet of the sand and gravel separator is connected with the water inlet of the sand and gravel separator. The water outlet of the sand and gravel separator is communicated with the sedimentation tank. The bottom of the sedimentation tank is provided with a slurry pump, and the water outlet of the slurry pump is connected to the mixing barrel In addition, a sludge pump is arranged in the mixing bucket, and the outlet of the sludge pump is communicated with the quantitative mixing bucket. The present invention has the effect of providing the recycling rate of cement slurry.

Description

technical field [0001] The invention relates to the technical field of concrete recycling, and more particularly, to a sorting and recycling device for cleaning water of a mixer truck. Background technique [0002] A mixer truck is a special truck used to transport concrete for construction; because of its shape, it is also often called a snail truck and an olive truck. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum is kept rotating to ensure that the concrete carried does not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the residual concrete from hardening and occupying space, so that the volume of the mixing drum becomes less and less. The water after cleaning the inside of the mixing drum still has more concrete power, and direct discharge will cause pollution to the environment and waste of resources. [0003] At present, t...
