Problems solved by technology

There are following defects in this conventional waste recycling system: (1) must support corresponding civil engineering facilities
The sand and gravel discharge height of the separation device is low, and corresponding civil engineering facilities must be provided to raise the equipment, causing the mixer truck to climb uphill when cleaning
(2) Large power loss and large water consumption for cleaning
The separation device requires many power sources and the control system is mostly manual and semi-automatic. Each process requires power and clean water, resulting in a large waste of power and clean water
(3) Mud water cannot be fully utilized
The separation device has no concentration detection device, so the concentration of the primary mud water cannot be accurately measured, so the mud water cannot be directly used as one of the raw materials for the production of concrete.

Embodiment Construction

[0028] Such as figure 2 Shown, the present invention is a kind of efficient concrete waste recycling method, and it comprises the following steps:

[0029] (1) Clean the mixer truck;

[0030] (2) Unload the waste concrete to the collection tank;

[0031] (3) washing waste concrete by agitated water;

[0032] (4) Send the cleaned sand and gravel to the sand and gravel separation system (screening drum) through the screw conveyor to separate the sand and stone that meet the raw materials;

[0033] (5) At the same time, the cleaned mud water is recycled and sent to the mud water mixing tank of the water circulation system. After stirring, the mud water is sent to the middle storage mixing tank, and the precipitated mud water is sent to the concrete mixing equipment; The separated water is sent to the collecting tank in step (2) for cleaning waste concrete; the clear water filtered in the mud water settling tank is pumped as the water for cleaning the mixer truck in step (1). ...

Abstract

The invention discloses a equipment for recycling concrete waste with high efficiency. The equipment comprises a sand-and-stone separating system, a waste concrete washing system and a water circulating system; the waste concrete washing system is connected with the sand-and-stone separating system by a screw conveyor and the water circulating system is connected with the waste concrete washing system. As the equipment send the slime water washed out into a collecting trough over again through the water circulating system, the filtered water is pumped to be used as the water for cleaning mixing carrier vehicles; thus the water can be highly utilized and the consumption of water for cleaning is little. A middle reserve stirring pool is arranged in the water circulating system and a concentration detecting device is arranged in the middle reserve stirring pool; thus the concentration of the primary slime water can be precisely determined and the slime water can be directly used as water, one of the raw materials for producing concrete.

Description

technical field [0001] The invention relates to a construction machine, in particular to a high-efficiency concrete waste recycling device. Background technique [0002] There will be a lot of unused or attached concrete in the pre-mixing drum of the ready-mixing truck, but before the next loading of concrete, the pre-mixing drum must be cleaned. Not only the concrete attached to the drum wall must be removed, but also the The unused concrete must be discarded, so the general ready-mixed concrete manufacturers have to deal with the dumping of waste, and cannot recycle the unused concrete. Therefore, how to make full use of the concrete waste remaining in the ready-mixing drum of the ready-mixing truck is the goal pursued by the industry. A conventional concrete waste recycling system (such as figure 1 shown), including a car wash 20 for cleaning concrete ready-mixed vehicles, a drum classifier 30, a pool group 40, and a mixing plant 50, and a motor-driven rotating motor is...
