Abstract

The invention relates to a continuous casting machine back washing water system device and a method for recycling back washing water of a continuous casting machine, and belongs to the field of steel production. The continuous casting machine back washing water system device comprises a sand filtering tank which is connected with a water storage tank by a pipeline; the water storage tank is connected with an intermediate tank by a pipeline; a water drainage outlet of the intermediate tank is connected with a pump; the pump is connected with a filter press by a pipeline; the filter press is connected with a back washing water tank by a pipeline. According to the invention, primary back washing water of the sand filtering tank is discharged into the water storage tank; reclaimed water in the water storage tank flows into the intermediate tank by a pipeline for stirring; meanwhile, a sludge-water mixture in the intermediate tank is conveyed into the filter press by a pump to filter, then sludge is remained in the filter press, and water is recycled and flows back to the back washing water tank of a water pump station to be reused. The device and the method provided by the invention are low in investment, and are simple and feasible; after primary back washing water in the sand filtering tank is treated and then recycled, and the using quantity of water is reduced; energy is saved; with the device and the method, the water expense of each continuous casting machine can be saved greatly each year.

Description

The method of conticaster backwash water system and device and recovery conticaster backwash water
Technical field
A kind of method that the present invention relates to casting machine backwash water system and device and recovery casting machine backwash water, belongs to iron and steel production field.
Background technology
At present, iron and steel production field conticaster pump works sandfiltration pot backwash water is outer discharge directly, both wasted the total draining processing of a large amount of water resource He Gei enterprises and strengthened burden.Industry energy conservation is reduced discharging simultaneously and reduce water consumption per ton steel amount and have certain influence.
Summary of the invention
The object of the present invention is to provide a kind of energy-conservation, consumption reduction conticaster backwash water system and device and reclaim the method for conticaster backwash water.
Technical solution
Casting machine backwash water system and device of the present invention, comprises sandfiltration pot, and sandfiltration pot is connected with water tank by pipeline, water tank is by pipeline and pans, pans drain outlet is connected with pump, and pump connects by pipeline filter press, and filter press is connected with backwash pond by pipeline.
The present invention reclaims the method for casting machine backwash water with casting machine backwash water system and device, method is as follows: a backwash water of sandfiltration pot is entered to water tank, water tank flows into pans by pipeline by the middle water of water tank and stirs, with pump, the mud mixture in pans is delivered to after Filter Press simultaneously, mud is stayed in filter press, water reclaims, and water is got back to pump works backwash pond and reused.
Small investment of the present invention, simple possible, by a backwash water of sandfiltration pot after treatment, reuses, and has reduced the consumption of water, energy-conservation, and after use the present invention, every annual conticaster can be saved approximately 260,000 yuan of water rates every year.
Accompanying drawing explanation
Fig. 1 is system architecture diagram of the present invention.
The specific embodiment
Embodiment 1
The present invention is being connected with water tank 2 by pipeline near sandfiltration pot 1 place, and water tank 2 is connected with pans 3 by pipeline, and pans 3 drain outlets are connected with pump 4, and pump 4 connects by pipeline filter press 5, and filter press 5 is connected with backwash pond 6 by pipeline.
With casting machine backwash water system and device, reclaim the method for casting machine backwash water, a backwash water of sandfiltration pot 1 is entered to water tank 2, water tank 2 flows into pans 3 by pipeline by the middle water of water tank 2 and stirs, with pump 4, the mud mixture in pans 3 is delivered to after filter press 4 filtrations simultaneously, mud is stayed in filter press 5, water reclaims, and water is got back to pump works backwash pond 6 and reused the effect that reaches energy-conservation, with the consumption of having entered to reduce water.The present invention is simple in structure, only need to be outside ready-made equipment, then build a water tank 2 and need 5.7 ten thousand yuan of RMB, and pipeline and valve arrangement need 90,000 yuan, once drops into money seldom, just can solve very large problem, is approximately 260,000 yuan of the annual water rates of enterprise.
