As Fig. 1, Fig. 7 and shown in Figure 8:
Be located at helical axis 6 outer filter drums and be divided into two sections, what connect with charging aperture 4 is low-pressure area filter drum 9, what connect with feeding plug tube is higher-pressure region filter drum 10, use Bolt Connection between two filter drums 9,10, the filter drum inwall is provided with the tread plate 32 of 4-8 bar projection, tread plate is installed in the groove of filter drum inwall 30, and is screwed, and filter drum is drilled with the little shoulder hole of outer imperial palace.
As Fig. 1, Fig. 9 and shown in Figure 10:
Be located on feeding plug tube 12 endoporus outside the optical axis material plug section 29 anti-wearing liner 13 is housed, circumferentially locate with 2-6 key 33 between anti-wearing liner 13 and the feeding plug tube 12, anti-wearing liner 13 inwalls are provided with 4-8 recessed non-slip groove.
As Figure 11, shown in Figure 12:
Anemostat 16 is circumferentially with 4-10 soup inlet port 14, and anemostat 16 is tapers, and in two, is connected into one by bolt 34.
The operation principle of Wood chip helical extruding and tearing machine of the present invention is:
Wood chip enters in the helicla flute from charging aperture 4, along with the rotation of helical axis 6, wood chip is carried in the space that is advanced into helical compression section and filter drum composition, and along with dwindling of helicla flute volume, wood chip is extruded, tears bunchy shape or silk bulk.Air, moisture content, water-soluble substances in the wood chip are extruded, and filtrate flows out to from the shoulder hole of the treatment hole of charging aperture bottom and filter drum and connects liquid bucket 5,7, discharges processing from filtrate (liquid 8 at last.Connect liquid bucket 5 and connect liquid bucket 7 and be communicated with, connect liquid bucket 5 and be provided with cleaning hose 3, on filtrate bucket 5, wash tub pipe 11 band when shutting down that is located on the filter drum is pressed flushing, to prevent the obstruction of filter drum filter opening with the fiber accumulations that prevents to flow out with filtrate.The material of extruding and tearing fasciculation, silk bulk is advanced into the space of optical axis material plug section and feeding plug tube composition by helical blade, form a solid material plug, this moment, the material mass dryness fraction was squeezed to about 60% by 30-35%, the specific area of material has increased about 10 times, this material plug has reduced the radial load of bearing as a fulcrum of helical axis; Filter drum is provided with the tread plate of projection, and the feeding plug tube anti-wearing liner is provided with recessed anti-slip tank, to prevent the material obstruction of skidding.Material is filled in and is advanced into anemostat by follow-up material, and volume increases suddenly, and pressure release absorbs the soup that adds from dosing mouth 14 rapidly, enters follow-up macerator from discharging opening 35 discharges after broken spiral 15 fragmentations.
Wood chip extruding and tearing eedle should be selected different helical compression ratios and material plug length to different raw materials and technological requirement, and generally in the 2.5-5 scope, compression ratio is big for its compression ratio, and extruding and tearing is effective, but the power that consumes simultaneously is big, and obstruction easily; The material setier is long, and material jam-pack degree improves, and power consumption simultaneously also can increase greatly, therefore must select suitable helical compression when to expect to fill in length according to different raw materials and technological requirement.Because helical axis is by carrying precommpression section 24, compression section 26, material plug section 29 to combine, by changing compression section 26 or material plug section 29, adjusting the length of the compression ratio or the material plug of helical axis, to satisfy different raw materials and technological requirement.Simultaneously helical compression section and optical axis material plug section by reason of heavy pressure, quick abrasion, service life is shorter, and carry the precommpression section little because of the little wearing and tearing of pressure, service life is longer, by changing helical compression section or optical axis material plug section, the adjusting that can conveniently produce reduces use cost.
Anemostat 16 is by the Taper Pipe of Bolt Connection by two halves up and down, unloading attachment bolt 34 reaches with the attachment bolt of feeding plug tube 12, discharging opening 35 and anemostat 16 and discharging opening 35 can be pulled down, pull down anemostat, discharging opening and just can unload broken spiral 15 at an easy rate, extract feeding plug tube 12 out, higher-pressure region filter drum 10 is changed optical axis material plug section 29 and compression section 26.
