Description

Sewage recovery system and circulation system for PC prefabricated component mill

Technical Field

The utility model relates to a waste water treatment technical field of prefabricated component factory, stirring station specifically is a be applied to sewage recovery system and circulation system of PC prefabricated component factory.

Background

At present, the sewage containing slurry generated by the operation of PC factory production lines, mixing plants and the like is directly discharged after precipitation, and the following problems can be generated: firstly, cement paste, sand and stones in the produced sewage are easily combined and hardened at the bottom of a sewage sedimentation tank, the hardened cement paste is high in strength, needs to be manually chiseled by means of electric drills, electric hammers and other devices, is difficult to clean, is easy to precipitate and accumulate again after being cleaned, and wastes a large amount of manpower and material resources; and secondly, the precipitated water is not recycled, is directly discharged, is relatively serious in waste, and is not beneficial to environmental protection and enterprise cost saving.

Chinese utility model patent CN204001083U discloses an assembled house building integration sewage treatment system, but this sewage treatment system passes through solid impurities such as sewage sedimentation separation grout, sand, stone, and at this moment, solid impurities hardens easily in the gunbarrel and blocks up the gunbarrel for the clearance degree of difficulty of gunbarrel is big.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the sewage recovery system and the circulating system can automatically clean sewage, prevent sewage from precipitation hardening and reduce production cost.

The utility model adopts the technical proposal that: the utility model provides a be applied to sewage recovery system of PC prefabricated component mill, includes sewage turnover pond, sewage stirring pond and solid-liquid separation equipment, be equipped with first agitating unit, second agitating unit in sewage turnover pond, the sewage stirring pond respectively, through first pipeline intercommunication between sewage turnover pond and the sewage stirring pond, through second pipeline intercommunication between sewage stirring pond and the solid-liquid separation equipment.

In the above scheme, sewage generated in a factory is collected in the sewage turnover tank through the pipeline, and can be prevented from precipitation hardening at the bottom of the tank through twice stirring in the sewage turnover tank and the sewage stirring tank, and then the sewage is separated from clear water through the solid-liquid separation device, so that the sewage is recycled.

Preferably, the utility model discloses a sewage recovery system still includes the clean water basin, the entry and the solid-liquid separation equipment intercommunication in clean water basin, the export in clean water basin is through third pipeline and first pipeline intercommunication. The separated clear water is stored through a clear water tank, and part of the clear water can clean the first pipeline through a third pipeline to prevent mud residues from depositing on the first pipeline,

Preferably, the outlet of the clean water tank is also provided with a fourth pipeline. The fourth pipeline can carry clear water to the mill and use, realizes the recycle of sewage.

Preferably, in order to prevent excessive sewage from precipitating in the sewage turnover tank, the capacity of the sewage turnover tank is not more than 15m for cultivation.

Preferably, the solid-liquid separation device is a filter press.

The utility model also provides a sewage circulating system, including foretell sewage recovery system, sewage recovery system's sewage turnover pond is connected with the sewage outlet of mill, solid-liquid separation equipment's liquid outlet passes through the clean water basin and is connected with the water inlet of mill.

The utility model has the advantages that:

1. the sewage in a factory is recycled, and water is saved;

2. the sewage recovery system can realize automatic cleaning, and saves manpower and material resources;

3. the sewage recovery system is simple to operate and convenient to implement;

4. the problem of sewage sedimentation is solved, and the occupied area of the system is reduced.

Drawings

FIG. 1 is a schematic view of the working process of the sewage recovery system of the present invention.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in figure 1, the sewage recovery system applied to the PC prefabricated part factory comprises a sewage turnover tank 5, a sewage stirring tank 7, a solid-liquid separation device 8 and a clean water tank 9. When in sewage treatment, sewage generated by a production line and a mixing plant of a factory 3 is pumped into a sewage turnover tank 5 by a water pump through a collecting pipeline 4; the sewage turnover tank 5 comprises a stirring device and a water pump, and can also be provided with a liquid level controller, when the sewage capacity reaches a certain height, the water pump is automatically started, and sewage is pumped into the sewage stirring tank 7 through the first pipeline 6; the sewage stirring tank 7 comprises a stirring device and a water pump, the sewage is stirred for the second time, impurities are brought up and conveyed to the solid-liquid separation device 8 through a second pipeline, solid-liquid separation is carried out in the solid-liquid separation device 8, wherein the solid-liquid separation device 8 can be a filter press, the separated water flows into the clean water tank 9, and solid residues are received through a movable receiving hopper below the filter press.

Clear water in the clear water tank 9 can be conveyed into the first pipeline 6 through the third pipeline 1 to carry out high-pressure washing on the first pipeline 6, and residues in the first pipeline 6 are precipitated and washed into the sewage stirring tank 7 to prevent the first pipeline 6 from being blocked; on the other hand, the residual clean water in the clean water tank 9 can be transported to the production line and the mixing plant of the factory 3 for use through the fourth pipeline 2, and the sewage generated by the production line and the mixing plant flows into the sewage turnover tank 5 again to form a circulation system.

Based on same design, the utility model also provides a sewage circulating system, including foretell sewage recovery system, sewage recovery system's sewage turnover pond 5 is connected with the sewage outlet of 3 mills, and solid-liquid separation equipment 8's liquid outlet passes through clean water basin 9 and is connected with 3 mills's water inlet.

The utility model provides a device such as agitating unit, water pump and pressure filter all can adopt the existing product in the market.
