Abstract
The utility model discloses a papermaking material preprocessing device which belongs to papermaking equipment and aims at providing a pulp manufacturing device which is small in volume and high in efficiency and uses a small quantity of water and alkali. The papermaking material preprocessing device comprises a reducer, an extrusion device and a stirring and delivering device, wherein the extrusion device comprises an extrusion container (5), and a taper spiral extrusion ram (4) which is arranged in the extrusion container and linked with the reducer (2); and the stirring and delivering device consists of a shell (9) communicated with the extrusion container (5), a vapor alkali liquor tube (6) arranged on the shell, two stirring shafts (11) arranged in the shell, a plurality of stirring blades (7) fixed on the two stirring shafts, a spiral propeller (10) fixed at the front sections of the two stirring shafts, a discharging hopper (14) fixed at the bottom of the shell (9), and gears (12) fixed on the two stirring shafts (11). The papermaking material preprocessing device has the advantages that the structure is simple and compact, the costs for manufacturing and running are low, the energy conservation and environmental protection are realized, and the like, thus being an ideal device for manufacturing pulp.
Description
Technical field: the utility model relates to a kind of paper making equipment, relates in particular to a kind of pulp production plant.
Background technology: well-known, paper industry adopts aqueous alkali that the method that the papermaking raw material of fibre rich such as timber, straw, bamboo carry out thermophilic digestion is prepared paper pulp usually at present; The chemical method of this production paper pulp not only can produce the waste water of a large amount of contaminated environment, and digesting apparatus also exists many defectives such as volume is big, complex structure, efficient is low, energy consumption is high, water consumption is big.
Summary of the invention: in order to overcome above-mentioned defective of the prior art, the utility model aims to provide the papermaking material pretreatment unit that a kind of volume is little, efficient is high, the water alkali charge is few.
To achieve these goals, the utility model is by the following technical solutions: it comprises decelerator, pressurizing unit and stirring conveying device, described pressurizing unit is by the conical recipient that is provided with loading hopper, the tapered screw pressure ram that is located in this recipient and connects with decelerator constitutes, described stirring conveying device is by the housing that is communicated with the recipient discharging opening, be located at the steam alkali liquor pipe on this housing, be located at two shafts in this housing, be separately fixed at the some stirring vanes on this two shaft, be separately fixed at the spiral propeller of this two shafts leading portion, be fixed on the discharge bucket of housing bottom, be separately fixed at pitch wheel formation on two shafts.
Stirring vane is in tilted layout along the material direction of propulsion.
Compared with the prior art, the utility model is owing to adopted technique scheme, therefore not only can utilize pressurizing unit that moisture content in the raw material and force air are extruded, and owing in extrusion process, produce high temperature, high pressure because of friction, when raw material are pushed when getting into the housing from the discharging opening of recipient, cause greatly raw-material volume moment by expanded expansion because of the space becomes suddenly, it is soft loose that material becomes; Thereby the alkali lye can fast Absorption steam alkali liquor pipe carried of raw material and steam and deliquescing.Meanwhile, under the powerful stirring action of stirring vane, the soft raw material that soaked into by alkali lye are dispersed into trickle fiber rapidly immediately and form paper pulp.The utlity model has that volume is little, simple and compact for structure, manufacturing and operating cost is low, production efficiency is high, water and plurality of advantages such as alkali charge is few, energy-conserving and environment-protective.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view among Fig. 1.
Among the figure: belt pulley 1 decelerator 2 loading hoppers 3 screw extrusion bars 4 recipients 5 steam alkali liquor pipes 6 stirring vanes 7 sleeves 8 housings 9 spiral propellers 10 shafts 11 gears 12 bearings 13 discharge buckets 14
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1~3, pressurizing unit is made of by the tapered screw pressure ram 4 that bearing 13 is bearing in this recipient respectively conical recipient 5, the two ends that the top is provided with loading hopper 3, this screw extrusion bar 4 connects with the output of decelerator 2, and the input of this decelerator is fixed with belt pulley 1.Stirring conveying device by the housing 9 that is communicated with recipient 5 discharging openings, the steam alkali liquor pipe 6 that is located at this case top, two ends respectively by bearing 13 be bearing in two shafts 11 in this housing, be separately fixed at some stirring vanes 7 on this two shaft, be separately fixed at this two shafts leading portion spiral propeller 10, be fixed on the corresponding discharge bucket 14 in housing 9 bottoms and this spiral propeller position and be separately fixed at that pitch wheel 12 constitutes on two shafts 11.For the ease of promoting material, stirring vane 7 is in tilted layout along the material direction of propulsion.For the ease of processing, stirring vane 7 and spiral propeller 10 can be fixed on the shaft 11 by the sleeve 8 that fixedly is connected as a single entity with it respectively.
