Abstract

The utility model provides a double spirals tobacco pulp extruding machine, including a material inlet port, a material outlet port thereon, a collection groove and an extrusion cavity of the discharge fluid port at the bottom, a horizontal propeller in the extrusion cavity and driven by the motor and provided with a spiral blade thereon, a filter net arranged at the edge of the propeller. The utility model is characterized in that the propeller is composed of an equant straight lever of the material inlet segment and a cone lever of the compression segment, the pitch of the spiral blade on the propeller is gradually decreased from the material inlet segment to the compression segment. The utility model not only improves the extrusion efficiency of the equipment, but decreases the compression force at the compression post segment, and completely eliminates the problem that the prior filter net at the post segment of the spiral pulp extruding machine is easy to be damaged, and greatly improves the service life and the reliability of the pulp extruding machine, and the whole body is made of stainless steel material, which meets the special requirement in tobacco pulping production.

Description

A kind of double helix tobacco press master

Technical field

The utility model relates to the press master that grows tobacco, especially a kind of efficient double helix tobacco press master.

Background technology

In the reconstituted tobacoo production process, the Double screw pulp extruder that the extraction of tobacco black liquor is all used in the paper technology is finished at present.Though be both the extraction black liquor, but because raw material difference, and the final use difference of product, so use the Double screw pulp extruder of paper industry can not satisfy comparatively harsh requirements such as tobacco business is efficient to press master, high reliability, no industrial pollution, therefore, be necessary fully prior art is improved.

Summary of the invention

The purpose of this utility model is to provide a kind of double helix tobacco press master that is applicable to tobacco business, in the hope of cutting down the consumption of energy, increases the recovery rate of black liquor, reduces and pollutes.

The utility model is realized by following technical proposal: a kind of double helix tobacco press master, comprise and which is provided with the charging and discharging mouth, its bottom is provided with the extrusion chamber of feeder and leakage fluid dram, be located in the extrusion chamber and by the motor-driven horizontal propeller which is provided with helical blade, be located at the screen pack of propeller outer rim, it is characterized in that propeller is made of the isometrical straight-bar of feed zone and the awl bar of compression section, the pitch of helical blade reduces to the compression section gradually from feed zone on the propeller.So that when satisfying its conveying function, increase compression stress, quick pressing materials, and reduce the extruding force that the compression section screen pack bears, prolong its service life.

The awl bar of described propeller compression section is that 0.8～2 afterbody awl bar constitutes by the middle part of tapering 2～4 awl bar and tapering, to improve the extruding force at middle part, reduces the extruding force that screen pack bears.

The utility model compared with prior art has following advantage and effect: by propeller being arranged to three different tapered sections, the pitch of the helical blade on it is set to the variable quantity that reduces gradually to the compression section from feed zone simultaneously, make this press master just to form extruding fast at the compression leading portion, improved the extruding efficient of equipment greatly, this press master has also reduced the compression stress of compression back segment, thoroughly eliminated the flimsy disadvantage of existing acroll press washer back segment screen pack, the service life and the reliability of press master have been improved greatly, all adopt the stainless steel material manufacturing in addition, satisfied the specific (special) requirements that tobacco slurrying is produced.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Extrusion chamber 1 one ends of press master are provided with charging aperture 2, the other end is provided with discharging opening 6, the bottom is provided with liquid collection trough 12, bottom land is provided with leakage fluid dram 11, be provided with level in the extrusion chamber 1 with decelerator 7, the propeller that motor 8 links to each other, this propeller is made as and is meshing with each other, two of forward and reverse rotation, each angle of rake feed zone is made as isometrical straight-bar 3, the compression stage casing is that tapering is 3.5 awl bar 4, the compression rear is that tapering is 1.7 awl bar 5, the pitch of the stainless steel helical blade 9 on each propeller reduces to the compression section gradually from feed zone, and helical blade 9 outer rims are provided with cylindric stainless steel screen pack 10.Material enters in the extrusion chamber 1 of Double screw pulp extruder from charging aperture 2, be meshing with each other, under two propeller effects of forward and reverse rotation, and the taper design by propeller different operating section with and on the variation of helical blade pitch, progressively compress material, the black liquor that stockpiles in the material and the air between the material are extruded the back to be flowed in the feeder 12 from the stainless steel screen pack, and, finish the process of material being extracted and extracted black liquor from leakage fluid dram 12 discharges.

Claims

1. double helix tobacco press master, comprise and which is provided with the charging and discharging mouth, its bottom is provided with the extrusion chamber of feeder and leakage fluid dram, be located in the extrusion chamber and by the motor-driven horizontal propeller which is provided with helical blade, be located at the screen pack of propeller outer rim, it is characterized in that propeller is made of the isometrical straight-bar of feed zone and the awl bar of compression section, the pitch of helical blade reduces to the compression section gradually from feed zone on the propeller.

2. double helix tobacco press master according to claim 1, the awl bar that it is characterized in that described propeller compression section are that 0.8～2 afterbody awl bar constitutes by the middle part awl bar of tapering 2～4 and tapering.
