Abstract
The invention discloses a kind of paper grade (stock) tail pulp recovery goal methods, including being arranged at the tail slurry collection for collecting tail slurry, tail slurry thinning tank of the installation for diluting tail slurry at tail slurry collection, clear water water inlet end is connected on tail slurry thinning tank, the tail slurry of collection is diluted by clear water, tail slurry after dilution is delivered to cyclone separator by stock pump, being delivered to rotary spherical digester by cyclone separator screw press rear screw realizes recycling.Beneficial effects of the present invention：The tail slurry that goes mouldy caused by tail slurry reduces weather influence is recycled by this programme to discard, and is worth 40,000 yuan in about 2 tons of year；And drying and manual sorting's expense are saved, about 30,000 yuan of year；Total annual 70000 yuan or so of expense of saving.And avoid carry and hoisting process in security risk.
Description
Technical field
The invention belongs to tail pulp recovery technologies in pulp technology for making paper more particularly to papermaking.
Background technology
Tail slurry also has recovery and reuse technology in papermaking traditional at present, but tail slurry currently on the market is mainly by boiling
Washed under ball material, mashing wash in material and desanding waste water be lost in fiber through boiling and wash beat Microfilter receive slurry, tail slurry through dehydration drying point
It is artificial to carry, lift to charging second floor and press technique overfall goal after inspection.This recycling has as a drawback that：
1. the tail-rotor collected needs to dry, usually because weather influences, can not timely reuse, or even cause to go mouldy discarded；
2. it is be easy to cause secondary pollution during drying, it can not reuse；
3. the drying tail-rotor of sorting qualification needs artificial carrying, lifts to second floor filling place, time-consuming and hidden in the presence of safety
Suffer from.
Invention content
The object of the present invention is to provide a kind of tail slurries to collect timely reuse, and the secondary pollution cut down the number of intermediate links avoids day
Influence of the gas factor to tail pulp recovery reduces the labour cost during tail pulp recovery, reduces production cost, avoids carry and hoist
Security risk.
To achieve the goals above, the technical solution used in the present invention is：
Tail pulp recovery goal method, including be arranged at the tail slurry collection for collecting tail slurry, installation is for dilute at tail slurry collection
The tail slurry thinning tank for releasing tail slurry connects clear water water inlet end on tail slurry thinning tank, and the tail slurry of collection is diluted by clear water, will be dilute
Tail slurry after releasing is delivered to cyclone separator by stock pump, and being delivered to rotary spherical digester by cyclone separator screw press rear screw realizes
Recycling.
Thinning tank installation site is less than cyclone separator, rotary spherical digester is directly installed on the lower section of cyclone separator.
The cyclone separator is one or more, is equipped with rotary spherical digester below each cyclone separator, and stock pump extremely
It is mounted on valve on the pipeline of cyclone separator.
At tail slurry collection and filling place is mounted on the device communicated at convenient for two.
The communication device is electric bell or intercom or signal lamp.
Beneficial effects of the present invention：The tail slurry that goes mouldy caused by tail slurry reduces weather influence is recycled by this programme to discard, year
About 2 tons, it is worth 40,000 yuan；And drying and manual sorting's expense are saved, about 30,000 yuan of year；Total annual 70000 yuan or so of expense of saving.
And avoid carry and hoisting process in security risk.
Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific implementation mode
With reference to embodiment, the present invention will be further described.
Tail pulp recovery goal method as shown in Figure 1, including be arranged at the tail slurry collection for collecting tail slurry, tail slurry is collected
Place is at the tail slurry collection on Microfilter, and tail slurry thinning tank 1 of the installation for diluting tail slurry at tail slurry collection is diluted in tail slurry
Clear water water inlet end is connected on tank 1, water inlet water inlet end can be directly connected to tap water, and the tail slurry of collection is diluted by clear water,
Dilution is controlled as needed, and agitating device can be arranged in thinning tank as needed, artificial stirring or machine stirring,
There is no precipitations after stirring, also more convenient when stock pump 4 conveys, and the tail slurry after dilution is delivered to by stock pump 4
Cyclone separator 2 is delivered to rotary spherical digester 3 by 2 screw press rear screw of cyclone separator and realizes recycling.It generally will dilution
Tank and rotary spherical digester are installed on one layer of position of floor, by the height that cyclone separator position design is at least one layer of floor.Institute
The cyclone separator 2 stated is one or more, rotary spherical digester is equipped with below each cyclone separator, and in stock pump 4 to cyclonic separation
It is mounted on valve on the pipeline of device 2.At tail slurry collection and filling place is mounted on the device communicated at convenient for two.Into one
It is electric bell 5 to walk as the preferably described communication device.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, those ordinary skill in the art's simply changes
All it is within protection scope of the present invention with replacing.
