Embodiment Construction

[0027] The present invention will be further described below through specific embodiments.

[0028] refer to figure 1 , figure 2 and image 3 , a residual wet concrete recovery system of the present invention includes a car washing tank 10, a sand separation unit 20, a hydrocyclone 30, a stirring tank 50, an automatic control unit 40 and a sedimentation tank 60. The sand and gravel separation unit 20 includes a wet concrete recovery machine 21 and a sand and gravel separation vibrating screen 22. The feed port 211 of the wet concrete recovery machine 21 is connected to the car wash tank 10, and the sand and gravel separation vibrating screen 22 is connected to the wet concrete recovery machine 21. The discharge port 212, the wet concrete recovery machine 21 is provided with an overflow port 213, the inlet 31 of the hydrocyclone 30 is connected to the overflow port 213 of the wet concrete recovery machine 21, the low concentration mud of the hydrocyclone 30 The water outlet...

Abstract

A residual wet concrete recovering system comprises a car washing tank, a sand and rock separating unit and a stirring pool; the sand and rock separating unit comprises a wet concrete recovering machine; the feed opening of the wet concrete recovering machine is connected with the car washing tank; an overflow port is formed on the wet concrete recovering machine; and the recovering system further comprises a pretreatment device used for pretreating muddy water separated by the sand and rock separating unit. Compared with the prior art, the residual wet concrete recovering system has the advantage that after muddy water overflowing from the wet concrete recovering machine is further separated by the pretreatment device, low-concentration muddy water conforming to concrete production requirements is discharged into the stirring pool, the muddy water entering the stirring pool does not contain solid particles any longer, and the concentration of the muddy water is reduced greatly, so that the production quality of concrete is ensured.

Description

technical field [0001] The invention relates to a residual wet concrete recovery system. Background technique [0002] With the wide application of commercial concrete, cement concrete mixing stations produce a large amount of waste residue and waste water while producing commercial concrete. The main sources of these waste residues and waste water are: cleaning discharges from concrete production such as mixing plants, mixer trucks, pump trucks, etc., and discarded concrete that has been ordered redundantly. Because these "waste water" and "waste residue" are strongly alkaline, with a pH value of about 12, and contain a large amount of insoluble matter such as cement and sand, if they are discharged without treatment, they will affect farmland water conservancy and block municipal facilities. , seriously affecting the environment. [0003] Due to the country's environmental protection requirements for concrete enterprises and the needs of enterprises themselves, residual ...
