Description
Technical Field
The utility model relates to a waste water treatment technology especially relates to a papermaking plain boiled water recycling system.
Background
The papermaking white water is waste water of a papermaking system and mainly contains a large amount of suspended matters such as fine fibers, fillers and the like. With the development of recent years, the elimination of small paper machines in China, the introduction, absorption and digestion of medium-high speed paper machines by domestic equipment manufacturers, the domestic medium-high speed toilet paper machines are more and more mature, and the price is greatly reduced compared with that of imported paper machines, so that the paper machines of toilet paper production enterprises are rapidly developed to the medium-high speed paper machines. With the stricter water taking and draining indexes of China, production enterprises are forced to treat white water generated in the production process and recycle the white water in a large quantity, so that a large amount of costs of pipe networks, water pools, water pumps and the like outside the system can be saved. The main equipment adopted by the papermaking white water recovery system mainly adopts air-floating white water return and gravity settling equipment.
In the field of household paper manufacturing, because the quantitative rate of the household paper is low, a medium-high speed toilet paper machine is almost adopted in the existing new project, and the requirement on the water quality of the paper machine spraying water is high. The gravity type settling equipment cannot meet the requirement of a high-speed paper machine on the filtering effect of water quality, and the air-floating type white water occupies a large area although the equipment price is lower; the system is complicated, an aerator or stirring equipment is required to be adopted to stir the water in the tank in the treatment process, and the precipitated impurities are easy to float back to the upper clear white water again, so that the impurity content in the white water obtained by final treatment is overhigh.
Disclosure of Invention
The utility model aims at providing a papermaking plain boiled water recycling system has the running cost low, deposits effectually, maintains convenient advantage.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a papermaking plain boiled water recycling system, constitute by a plurality of drum section sedimentation tanks, the inlet tube gets into on by first sedimentation tank, the end is connected to the play water pipe of lower part in the first sedimentation tank through the vertical section, it is equipped with a plurality of holes to go up the water pipe, the connecting pipe is led to on first sedimentation tank upper portion, the connecting pipe is connected to the play water pipe of lower part in the second sedimentation tank through the vertical section, all the other sedimentation tanks interconnect are the same with first sedimentation tank and second sedimentation tank connected mode, the outlet pipe is connected on the upper portion of final sedimentation tank.
The bottom of each sedimentation tank is conical and is connected with a sludge discharge pipe, the sludge discharge pipe is respectively connected with a sewage discharge pipe, and a sewage discharge valve is arranged at the outlet of the sewage discharge pipe. The sediment enters the blow-off pipe through the mud pipe, and when a certain amount of sediment is reached, the sediment can be discharged by opening the blow-off valve. Or when the white water in the sedimentation tank needs to be completely discharged, the white water can be completely discharged through the drain pipe. The distance between the water emitting pipe and the bottom of the conical tank is about 30-50cm, and the part below the water emitting pipe can be a settling area and cannot be disturbed by the inflowing white water.
Every sedimentation tank sets up scrapes the mud device, scrapes the mud device and includes, mount, motor and scraper blade, and the mount is installed at the sedimentation tank top, and motor fixed mounting is on the mount, and the drive shaft and the scraper blade of motor are connected. The scraper blade edge is the rubber material, can scrape down adnexed precipitate on the sedimentation tank limit wall, and during papermaking plain boiled water recycling system was regularly cleared up, white water in the evacuation sedimentation tank started and scraped mud equipment, and the motor drive scraper blade slowly rotated in the sedimentation tank and will accumulate the mud of scraping at the sedimentation tank inner wall and fall, and the clearance personnel are also easy relatively through washing and scrape the mud rubber slab, and mud is discharged from the mud pipe of sedimentation tank bottom. The wall of the sedimentation tank can be paved with ceramic tiles, so that the adhesive force of dirt is reduced, and the cleaning is convenient.
The working principle is as follows:
the papermaking white water flows into the water emitting pipe of the first-stage sedimentation tank along the water inlet pipe, the white water slowly escapes into the sedimentation tank from the water emitting hole above the water emitting pipe under the action of natural gravity, sediment in the white water is settled to the bottom of the tank under the action of gravity, and the water flowing out of the water emitting pipe cannot stir the sediment at the bottom of the tank because the water emitting hole is upward, and the water on the upper layer of the sedimentation tank is clean water with less impurities; the plain boiled water on upper strata flows out the gassing pipe of second sedimentation tank through the connecting pipe, deposits through the second grade, and the third level of rethread income is analogized to this, and after plain boiled water settled through a plurality of grades, the outlet pipe that gets into last one-level sedimentation tank flowed out and can get back to the papermaking process retrieval and utilization.
The utility model has the advantages that:
1. the utility model discloses compare with traditional plain boiled water sedimentation tank, utilized the water head between the sedimentation tank to realize the flow of plain boiled water between the sedimentation tank, accomplish and deposit step by step, need not add equipment such as establish water pump, can practice thrift running cost, the energy can be saved.
2. The slow flowing water discharging mode of the middle water emitting pipe of the utility model can not excite the sediment deposited at the bottom of the original pool, so that the deposited and layered upper layer white water is mixed with the sediment again; filtering devices such as a filter screen are not required.
3. The utility model discloses utilize rotatory mud device of scraping to scrape the mud of lateral wall and scrape the discharge, reduce the work load of artifical clearance, use manpower sparingly.
