Background technology
Defibrination is an important workshop section of papermaking, mainly is the method pulp treatment suspension that adopts machinery, makes paper pulp obtain to have a kind of flow process of paper grade (stock) performance.The normal fiberizer that adopts carries out the defibrination processing to paper pulp fiber in the production.Copy the needed beating degree numerical value of paper in order to reach, many fiberizers series connection of general employing are used in the production, but the disposable input of many fiberizer needs is higher, the maintenance and repair expense is than higher, the technology that the papermaking enterprise of, financial strain smaller for scale, many fiberizer series connection use is unfavorable.Plant for example heavy wall softwood pulp, hardwood slurry for more reluctant slurry, perhaps beating degree requires than higher paper kind, if the daily output is little, can adopt the method for separate unit fiberizer circulation defibrination to substitute many fiberizer series connection defibrinations.
Existing circulation grinding method and device exist some defectives, it is unreasonable with device to be mainly reflected in circulation technology, causes the paper pulp of different cycle-indexes to mix easily, causes pulp quality inhomogeneous, reduced the efficient of circulation and the performance indications of pulping, and energy-saving effect is undesirable.
The utility model content
The purpose of this utility model is to overcome the defective and the deficiency of existing circulation defibrination device, and a kind of circulation defibrination device of locellus reversible of anti-mixing is provided, and uses this device can improve the efficient of the quality uniformity and the defibrination of pulping.
For achieving the above object, technical scheme of the present invention is as follows: a kind of locellus reversible circulation defibrination device is characterized in that: comprise having two storage pulp grinder structures with upper chamber, advance to starch device and fiberizer; The outlet of each chamber of described storage pulp grinder structure is connected with the inlet that advances to starch device respectively, and the outlet of advancing to starch device is connected in the inlet of fiberizer, and the outlet of fiberizer is connected with the inlet of each chamber respectively through the pulp pipeline;
The chamber of described storage pulp grinder structure for separately independently slurry can or separate by slurry can obtain;
With the switching that is provided with the valve control piper in the pipeline that each chamber of storage pulp grinder structure links to each other.
In the said apparatus, the chamber quantity of described storage pulp grinder structure is generally 2.Adopt a plurality of chambers mainly to be based on and can access different defibrination degree, and can carry out the consideration of the complication system of different material defibrination simultaneously, certainly in such cases, can with many fiberizer couplings.
As a kind of comparatively preferred construction, described storage pulp grinder structure is one and become the slurry can of two chambers by longitudinal subdivision, for example described storage pulp grinder structure can be about longitudinal baffle be divided into two chambers, in order to prevent the dividing plate distortion, block board thickness is generally 8-12mm.The volume of above-mentioned two chambers is preferably identical.
In order to prevent that slurry from storing up the delay on the pulp grinder structure wall and increasing the potential energy that slurry flows downward, described storage pulp grinder structure is that cylinder awl die bed or side are tapered.
Be the operation on convenient the production, with the valve that is provided with in the pipeline that each chamber of described storage pulp grinder structure links to each other preferably pneumatic operated valve or electromagnetic valve;
In order to guarantee that paper pulp carries smooth and easy and ripple disable, describedly advance to starch the device outlet and seamlessly transit with the employing horn mouth that is connected of fiberizer inlet.
For guaranteeing in each chamber of storage pulp grinder structure the cloth slurry evenly, grout outlet can be connected by the locellus pipe that is arranged in parallel with each chamber, the locellus pipe vertically be suspended from corresponding chambers entoplasm fluid level directly over; The locellus pipe is vertical the connection with the coupling part of grout outlet.
The used fiberizer of apparatus of the present invention is generally low dense fiberizer (refining concentration is 3-6%) or middle-density refiner (6-12%).
Adopt the device provided by the invention defibrination that circulates, can avoid the mixing of different cycle-index paper pulp, improve the efficient of circulation defibrination, reduced the energy consumption of circulation defibrination and can improve and ground that afterwards pulp quality is even.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred implementation of the utility model;
Wherein: 1 dividing plate, 2 storage pulp grinder structures, 7 tapers advanced to starch device to pipe valve in 6 minutes to pipe valve in 5 minutes, 8 fiberizers, 9 grout outlets, 10 locellus pipes, 11 locellus pipes, 12 locellus pipe valves, 13 locellus pipe valves, 14 coarse fodder inlet tubes to pipe in 4 minutes to pipe in 3 minutes; Two chambers that on behalf of storage pulp grinder structure 2, A, B be separated into by dividing plate 1 respectively.
The specific embodiment
Provide a kind of preferred specific embodiment of the present utility model below, but embodiment of the present utility model is not limited in this.
As shown in Figure 1, this device comprises a storage pulp grinder structure 2 with two chamber A and B, and taper advances to starch device 7 and fiberizer 8; Two chamber A of storage pulp grinder structure 2 and the outlet of B respectively by divide to pipe 3 and divide to manage 4 and the taper inlet that advances to starch device 7 be connected, taper is advanced to starch the outlet of device 7 and is adopted horn mouth to be connected smoothly in the inlet of fiberizer 8, the outlet of fiberizer 8 connects pulp pipeline 9, is connected with the inlet of chamber A and B respectively with locellus pipe 11 through locellus pipe 10;
The branch that is connected with B with chamber A to pipe 3, divide in pipe 4, locellus pipe 10 and locellus pipe 11, corresponding be respectively equipped be used for branch that control piper opens and closes to pipe valve 5, divide to pipe valve 6, locellus pipe valve 12 and locellus pipe valve 13.
