Shorten the length of rotating shaft between rotating disk and bearing, effectively improve the stressed distribution of whole rotating shaft, the performance that makes rotating shaft resist external impacts is improved, and in the installation and removal process, is difficult for taking place to cause owing to colliding with the problem of shaft bending.
On the coating bulkhead, being 120 degree central angle places with nozzle position has an axial band (swath height can be done with adjustment according to instrument size, coating liquid characteristic etc.; Also can; Band lower edge and coating rotating disk are apart from 1mm, and upper limb is concordant with the coating Hatch Opening), this band is positioned at the below of rotating disk direction of rotation; Be fixed in coating storehouse inwall with screw, can dismantle or change.
Shower nozzle becomes the 30 degree angles of the crossing apart from disc height 2cm with the coating bulkhead, reduces coating liquid and is sprayed onto the probability on the coating bulkhead.Shower nozzle is given prominence to coating storehouse inwall 1cm.The shower nozzle front end is taper, and the axial section of taper is 30 ° of angles, effectively reduces between shower nozzle and coated granule to contact area, avoids shower nozzle mouth adhesion coated granule, causes the bad problem of coating liquid atomizing.
Charging aperture (see figure 4) and discharging opening (see figure 5) that hydraulic control is arranged on the fluidisation encapsulation tool, make equipment both can manual input and output material also can automatic feed/discharge, improve the efficient of the material that changes the outfit, save manpower.
Lower end, coating storehouse is an air inlet, is connected with firing equipment through a pipeline with hydraulic lift.Hot-air in the firing equipment gets into from bottom, coating storehouse, passes the space between rotating disk and the coating bulkhead, both Heating rotary-disc and coating warehouse; Blow the material particles of fluidisation again; Strengthen grain fluidizedly, get into the solvent evaporates storehouse then, after the exhaust collection storehouse gets into induced draught system.
