Description
Technical field
The present invention relates to a kind of press dewatering technologies, especially suitable for the black liquid extraction and food of paper making pulp, chemical industry
Etc. industries need a kind of double helix squeezing dewatering machine of press dewatering.
Background technology
Paper making pulp black liquid extraction and food, chemical industry separation of solid and liquid process in, due to double helix press dewatering
The advantages that equipment high efficiency, does not block, and floor space is small, and operating environment is hygienic, and be widely adopted.But hair in use
It is existing, since helical axis compression ratio is certain, only when charging is sufficient and moisture content is stablized, it just can guarantee that discharging moisture content is relatively low,
And in the actual production process, often there is phenomenon under feeding or that charging moisture content concentration is relatively low, is difficult to ensure at this time
The moisture content of discharging causes discharging moisture content higher, and difficulty is caused to next procedure processing.
Invention content
The present invention provides a kind of a kind of double helix squeezing dewatering machine that can ensure discharging moisture content under complex working condition and stablize.
The technical scheme is that：A kind of double helix squeezing dewatering machine, including transmission mechanism, rack, cylinder mould, spiral
Axis, feed bin, discharging babinet, liquid dish, tapered pressure disk, compression cylinder, two tapered pressure disks are mounted on side by side
The discharge end of two helical axis, endoporus and helical axis discharge end slide fit, and each tapered pressure disk can discharge along helical axis
Independent slide, the compression cylinder is held to be mounted on discharging babinet, cylinder piston rod front end is hinged with tapered pressure disk, described
Compression cylinder at least arranges two on each tapered pressure disk, described to apply stressed mode to tapered pressure disk, also may be used
Using spring or hydraulic cylinder.
Compared with prior art, the present invention with inlet amount and charging moisture content wide adaptability, discharging moisture content is stablized
Advantage.
Description of the drawings
Fig. 1 is the front view of the present invention
Fig. 2 is the vertical view of the present invention
Fig. 3 is the A-A sectional views of Fig. 1
Fig. 4 is tapered pressure disk scheme of installation
Specific implementation mode
In order to solve the defect of existing double helix squeezing dewatering machine, the present invention uses following technical proposals, transmission mechanism 2,
Discharging babinet 4, feed bin 8 are fixed on the upper plane of rack 1, and cylinder mould 6 is the structure of falling figure-eight knot, and one end is fixed on discharging babinet
Right side, one end are fixed on the left of feed bin, and two helical axis 7 are supported on across cylinder mould feed bin and discharging babinet
In bearing block, two transmission gears 3 are attached separately to left end and the intermeshing of two helical axis, and two tapered pressure disks 5 are arranged side by side
Mounted on the discharge end of two helical axis, endoporus and the helical axis discharge end slide fit of two tapered pressure disks, each tapered pressure
Disk can be mounted on along helical axis discharge end independent slide, compression cylinder 11 on discharging babinet, 10 front end of piston rod and tapered pressure
Disk is hinged, and each tapered pressure disk arranges 4 compression cylinders, to ensure that tapered pressure disk stress equalization, liquid dish 9 are arranged in machine
The lower section of cylinder mould inside frame, for collecting the liquid squeezed out.
Operation principle：Material to be extruded enters feed bin, passes through the relative rotation of two reducing variable-pitch auger axis, object
Material is advanced to, and in the transmission process of helical axis, the volume of helical axis is gradually reduced, and material, which is squeezed, to be started to be dehydrated,
Discharge end is more arrived, the volume of helical axis is smaller, and the extruding force that material is subject to is bigger, and when reaching discharge end, being extruded material needs
The thrust for overcoming tapered pressure disk is discharged along the conical surface of tapered pressure disk；When occurring, charging is discontinuous or input concentration is low
The phenomenon that when, when material reaches discharge end, moisture content is higher, due to there is tapered pressure disk, material is made further to be dehydrated,
When material can overcome the thrust of tapered pressure disk, it will discharge along the conical surface of tapered pressure disk, ensure that in this way
In the case that charging is discontinuous or input concentration is relatively low, lower discharging moisture content also can guarantee, it can be by adjusting cylinder
Air pressure, to adjust the pressing force of cylinder, with the moisture content of control discharging.
