DGJ series single screw extrusion Machine, pulp is based on a variety of different size, in and out of the slurry Concentration, freeness, PH, temperature and other parameters of the elaborate Design and production, professional for the waste-water, mooring plant pulp Cooking cotton pulp black liquor extraction and the cotton pulp washing and Concentration, it can use single also can be used in series or parallel. It is Also suitable for waste pulp dehydration and washing and concentration.

Structural features:

the spiral shaft of this machine adopts the large cone, the blade adopts the whole change, and the size of the slurry Decreases gradually to achieve the purpose of extrusion dehydration. the machine Adopts pneumatic control system to adjust the back pressure of the material to Obtain the ideal dry degree, and the sieve and sieve are both.

this machine has the advantages of large Compression, simple operation, low energy consumption, good concentration Effect, stable plasma concentration and reliable operation.

USES:

the single helical squeezer is mainly Used for the extraction of black liquor and concentrated dehydration of pulp in the pulping process of the paper mill, so as to meet the requirements of the Slurry concentration.

Description of equipment structure

Single screw extrusion machine mainly Include feeding, screw shaft, main bearing, bearing department filter drum, Intermediate support, strengthen, screen, screen frame, long feeding mouth, Tail, discharging department, frame, hood, cylinder, is expected to plug, Transmission, small brackets, etc.

A. Transmission device: inverter, motor, Reducer, coupling, etc. the rotation speed of the spindle can be adjusted by the Frequency converter, and the production capacity of the equipment can be Improved when the rotational speed of the spiral shaft is improved, and the Cadre degree can be raised when the rotation speed of the screw is reduced.

B. Screw axis: first contact a paste for Conveying screw section, the middle part of the screw shaft conical varying Pitch screw axis to increase the compression ratio, improve the extraction yield and slurry filtrate dryness, second half is divided into high pressure spiral, Spiral blade pitch from the inlet to the discharging mouth from small to large Order.

C. Sieve drum: inlet section, prefilter Segment, filter segment, compression section, outlet section, etc. the inner Layer of the sieve drum is the screen mesh, the screen is made of stainless Steel plate opening the hole, the pore diameter from the feeding mouth to the Outlet from the small to the large arrangement. the outer layer of the screen is Reinforced. the mesh is bolted.

D. Frame: the inside of the frame is a Receiving tank, and the extruded liquid is discharged from the bottom outlet.

E. Cylinder, material plug: the cylinder Is adjusted to dry, and the air pressure inside the cylinder should be increased When the discharge drying is low, and the air pressure inside the cylinder Should be reduced when the drying degree is high. Until the discharge is Suitable. (note: the air pressure in the cylinder should be reduced when the Motor load is too large.)
