Wastewater recovery device for trial production of hot-rolled ribbed steel bars and use method of wastewater recovery device

Abstract

The invention discloses a waste water recovery device for hot-rolled ribbed bar trial production and a using method thereof, and relates to the technical field of hot-rolled ribbed bar production waste water recoverability. The waste water recovery device comprises a base, the top of the base is fixedly connected with a first filter box, and two limiting columns are fixedly installed on the inner wall of the first filter box; the sewage treatment device has the beneficial effects that the first filter box, the preliminary filter box and the ultraviolet filter box are arranged, wastewater is filtered through the preliminary filter box and the ultraviolet filter box, multi-stage filtration is achieved, a reciprocating anti-blocking mechanism is arranged, and the sewage treatment effect is improved. The device is provided with a first filter box and a filter mechanism, reduces the blockage of the surface of a first filter plate, reduces the frequent manual cleaning, is provided with a second filter box and the filter mechanism, achieves the self-cleaning operation, reduces the labor intensity of workers, is provided with a cleaning assembly, carries out heating through a heating rod, assists in residue cleaning, and facilitates the unified cleaning of workers in the later stage.

Description

technical field [0001] The invention relates to the technical field of recycling wastewater from production of hot-rolled ribbed steel bars, in particular to a wastewater recovery device for trial production of hot-rolled ribbed steel bars and a method for using the same. Background technique [0002] The hot-rolled ribbed steel bar for reinforced concrete is a steel bar made of low-alloy killed steel and semi-killed steel. It has high strength, good plasticity and welding performance. Joint force, widely used in large and medium-sized reinforced concrete structures, can be used as prestressed steel bars after cold drawing. During the trial production of hot-rolled ribbed steel bars, a large amount of wastewater will be generated, and direct discharge will easily cause waste of water resources and environmental pollution, so recycling is required. [0003] The existing technology is relatively rigid, and the existing waste water recovery device will generate a large amount ...

AI Technical Summary

Problems solved by technology

During the trial production of hot-rolled ribbed steel bars, a large amount of wastewater will be generated, and direct discharge will easily cause waste of water resources and environmental pollution, so recycling is required

[0003] The existing technology is relatively rigid, and the existing waste water recovery device will generate a large amount of residue when filtering waste water, which is easy to cause blockage to the overall filter plate, and the residue is not cleaned up in time, and it is not convenient for the staff to clean up , resulting in a large amount of labor, so the present invention needs to design a waste water recovery device for trial production of hot-rolled ribbed steel bars and its use method to solve the above-mentioned problems
