Description
Technical field
The utility model relates to the Bleaching Technology field, relates in particular to a kind of bleaching tower.
Background technology
Bleaching process for softwood pulp and bardwood pulp, true qualities paper pulp is processed with bleaching agent, deviate from paper pulp coloring matter and other foreign material to improve whiteness and purity, this technical process all need to be carried out by special bleaching equipment the bleaching of paper pulp usually, the bleaching tower that tradition is used, bleached after in the paper pulp in tower body, dropping into the bleaching agent hybrid reaction, then obtained bleached pulp;
In addition, the paper pulp that arrives the tower body bottom also easily produces the bridging phenomenon, be unfavorable for that paper pulp discharge tower body enters in next process, therefore adopt the problem that the dilution water inlet solves above-mentioned bridging is set on tower body, but entering in tower body, dilution water can have certain pressure, will enter into the mixture slurry that the tower body upper strata enters paper pulp and bleaching agent, dilution water reduces the concentration dilution of bleaching agent, do not reach bleaching agent required optium concentration of when bleaching, greatly reduce the association with pulp bleaching effect, pulp quality is poor, inefficiency.
The utility model content
The purpose of this utility model is to provide a kind of bleaching tower, to solve the poor technical problem of traditional paper pulp bleaching effect.
The utility model is to realize like this, a kind of bleaching tower, comprise tower body, described tower body top is provided with stock inlet, be provided with the bleaching chamber and the dilution chamber that are interconnected in described tower body, described bleaching chamber is positioned at the top of described dilution chamber, and described stock inlet is communicated with described bleaching chamber, tower body cross sectional shape corresponding to described dilution chamber is taper, and the tower body of described taper is provided with some water inlets.
As further improvement, the described tower body inwall that is positioned at described water inlet top is provided with for preventing from blowing back into into water the guiding device in described bleaching chamber, and described guiding device is positioned at described dilution chamber.
As further improvement, described guiding device comprises several and described water inlet baffle plate one to one, and described baffle plate tilts to be installed on described tower body inwall, and described baffle plate tends to described water inlet direction.
As further improvement, described guiding device comprises cone-shaped hood, and the large end of described cone-shaped hood is fixedly installed on described tower body inwall.
As further improvement, the described tower body that is positioned at described dilution chamber is provided with the transport of deriving from described tower body bottom for the paper pulp after bleaching.
As further improvement, described transport comprises rotating shaft and is arranged at the screw body on described rotating shaft.
As further improvement, described tower body bottom connects a slurry case, and described rotating shaft is through described slurry case, and described slurry case is provided with dilution water import and grout outlet.
After having adopted technique scheme, the beneficial effects of the utility model are:
Owing on the tower body inwall, guiding device being installed, baffle plate or cone-shaped hood, so just can stop that dilution water enters into the bleaching chamber, thereby guaranteed reliably the best bleaching concentration between paper pulp and bleaching agent, can obtain highly purified bleached pulp, greatly improved bleaching effect and production efficiency, simple in structure, easy to use.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1, tower body, 2, the bleaching chamber, 3, dilution chamber, 4, baffle plate, 5, water inlet, 6, rotating shaft, 7, the spiral slurry, 8, the slurry outlet, 9, the slurry case, 10, the dilution water import, 11, grout outlet, 12, stock inlet.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of bleaching tower, comprise tower body 1, tower body 1 top is provided with stock inlet 12, is provided with the bleaching chamber 2 and the dilution chamber 3 that are interconnected in tower body 1, bleaching chamber 2 is positioned at the top of dilution chamber 3, stock inlet 12 is communicated with bleaching chamber 2, and tower body 1 cross sectional shape of dilution chamber 3 correspondences is taper, and the tower body of taper is provided with some water inlets 5, tower body 1 inwall that is positioned at water inlet 5 tops is provided with for preventing from blowing back into into water the guiding device in bleaching chamber 2, and guiding device is positioned at dilution chamber 3.
Guiding device comprises several and water inlet 5 baffle plate 4 one to one, and baffle plate 4 tilts to be installed on tower body 1 inwall, and baffle plate 4 tends to water inlet 5 directions.
Guiding device comprises cone-shaped hood, and the large end of cone-shaped hood is fixedly installed on tower body 1 inwall.
The tower body 1 that is positioned at dilution chamber 3 is provided with the transport of deriving from tower body 1 bottom for the paper pulp after bleaching.
Transport comprises rotating shaft 6 and is arranged at the screw body 7 on rotating shaft 6.
During use, from water inlet 5 to tower body, pass into dilution water 1, dilution water can directly flow in dilution chamber 3 along baffle plate 4, can not enter into bleaching chamber 2, makes between bleaching agent and paper pulp and can guarantee best bleaching concentration, with this, obtains highly purified bleached pulp;
Paper pulp after bleaching enters in dilution chamber 3, then under the drive of helix transporting device, slurry outlet 8 from tower body 1 enters in slurry case 9, and then diluted in slurry case 9, enter in next process, during dilution, the dilution water import 10 from slurry case 9 passes into water and dilutes and get final product.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
