We (Zibo Baotang Chemical Equipment Co.Ltd) have glass-lined double cone rotary vacuum dryer (GMP & non GMP standard) and SS Double cone rotary vacuum dryer:
Performance&Specification
1)Design pressure:
Vessel inside: -0.1Mpa(vacuum) Jacket< 0.1Mpa
2)Max. Working pressure:
Vessel inside: -0.1Mpa(vacuum) jacket< 0.1Mpa
3)Medium: Organic powder material (pH< 12)in the shell, water or vapor in the jacket.
4) Maximum temperature: 140centigrade degree (for example when user request oil heating may be bigger than with design relation temperature 140centigrade degree)
5)Shell of tank rotational speed: 4~8 revolution of/minutes (when user request may match velocity modulation electrical machinery)

1,working principle
This dryer under the vacuum condition, carries on the heating in the jacket by the steam or the hot water, is directly through the hot energy in the shell inside and the wet materials contact, depends on the tube body rotation, tumbles unceasingly the material. After the material heat absorption evaporates the steam, extracts outside continuously the tube through the vacuum pump after the steam exhaust pipe, thus speeds up the material the drying velocity, tumbles unceasingly along with the material, achieves the material even dry goal. This equipment and the heating area same general drying box and the kang type heater compares, the dry thermal efficiency may become time of enhancement, and can improve the work condition and the labor intensity.
 
2,Use of    GL  RCVD
This factory production dryer is one kind of multipurpose machine, is suitable in powdery or granular material vacuum drying and the mix, also is suitable specially in has the following request material.
    1). Cannot accept the high temperature;
2).  Easy to oxidize;
3). Has the strict request to the crystallization shape;
4). Has the strict limit to the metallic ion content;
5). Requests the remaining volatile matter content to be extremely low;
6). Dry when discharges the steam must recycle.
The material the dry merit may evaporate under the vacuum for the volatile matter under the low temperature, may be suitable hotly sensitive, the hatred oxygen class material is dry, in the shell of tank the glass lining, has smoothly, clean does not cake characteristic of the material
Uses this aircraft to be possible to arrange several operation sequences in a machine completes successively. Therefore can save the equipment, reduces the operating time, saves the energy, reduces the labor intensity, reduces the leak and the impurity mix opportunity, thus may obtain the high-purity product.

2)Max.working pressure:
Vessel inside: -0.1Mpa(vacuum) jacket<0.1Mpa
3)Medium: Organic powder material (PH<12)in the shell, water or vapor in the jacket.
4) Maximum temperature: 140ºC (for example when user request oil heating may be bigger than with design relation temperature 140ºC)

                       4,Operation specification of dryer   
1)The closure puts the material hole cap
2)Opens feeds the lid, starts to feed, feeds the volume not to have to surpass the nominal volume 50%.The material does not have to smuggle has massive hard.
3)The closure feeds covers
4)Closes the power switch, the shell of tank starts to revolve.
5)On the opening pumping air pipeline vacuum valve, in the pot namely implements the negative pressure operation.
6)The opening pumping air heating with the steam valve, (or hot water valve, cooling water valve), must pay attention, when this aircraft heating or cooling, should carry on slowly. Heat resistant emergency cold impact 110ºC, thermal shock 120ºC.According to the pot in the material granularity, the water content and the permission heating temperature, should use the suitable elevation of temperature speed, in the clamp cover steam pressure is highest does not have to surpass 0.1Mpa.
7)In after the pot the material dry mix completes, the cut-off steam and the aspirator line, then pass the cooling water to the clamp cover, waits the material to cool after the specified temperature, presses the electrical machinery "the stop" the button, causes to put the position which the material mouth changes to needs.
8)Turns in the exhaust pipeline the dump valve, causes the shell of tank interior connection atmosphere.
9)Turns on lathe the pine to put the fastening installment which the material covers, the rotation puts the material valve cover, then puts the material.
10)materials dump the shell of tank completely, should sweep clear in the pot the residuum, and closes puts the material hole cap.
11)In the machine operation process wants when carries on the middle sampling observation, should according to the 7th stipulation cause the machine first to stop, then presses 8, 9 stipulations again, opens puts the material hole cap to carry on the sample.After the sample finished, the closure puts the material hole cap, should according to 4, 5, 6 and so on the strip stipulations drive.
 
5,Maintenance
1)In the rolling bearing fills up the MOS2 compound calcium lubricant.
2)In the worm gear decelerator recommends uses the 40# machine oil.
3)On the exhaust pipe teflon packing ring itself had the lubricity, therefore should not again spread the lubricant in the packing surface, in order to avoid pollutes in the pot the material.
4)When the this aircraft does not use for a long time, should survive the shell of tank in the material to discharge, and is clean with the clear water flushing, turns in the clamp cover the drain cock, survives the clamp cover in the water platoon to fall to the part does suitable rust prevention processing.
5)The clean or replaces when the filter the cloth, should open feeds the lid, grips the filter with the hand to revolve several, then upwardly takes out the filter, takes out and installs when the filter should be specially careful, do not have to bump in the bad pot the glass lining level.
This factory provides the this aircraft to the user to need each kind of vulnerable seal packing collar spare parts.
 
6.Installment and trial test

1. When transporting and hoisting this dry, should the whole hoisting up, not have to disassemble, the hoisting up steel wire lock ties up on the machine four hangs on the hole (or equipment both sides main axle), for details sees installs the schematic drawing.
2. The this aircraft may place in the concrete grounds around a house, or installs in thickness is directly in 400 millimeter concrete foundations, after the installment the shell of tank centerline maintains the level.

3)craft pipelines install
(1) enter the water (steam) orifice G to enter, meet the hot water or the steam.
(2) condensate orifice G leaves, meets the return main line or the backwater pipeline.
(3) exhaust orifice G pulls out, needs according to the production to be possible with vacuum, the compression gas tube to connect the pipe accessory which on various crafts pipeline must dispose, supplies for oneself by the user. Installs when enters the water with the this aircraft (steam) the orifice, the condensate orifice, the exhaust orifice connection pipeline wants the hose connection, in order to avoid creates the revelation and so on.
(4)puts through the power source.
 Installs the schematic drawing to explain
I.Condensate exportation, the hot medium import, the exhaust orifice and the pipeline attachment point must use the hose connection.
II. charts installs needs the fitting, supplies for oneself by the user.
III.machines may install in the 400mm concrete foundation, also may place directly in the concrete grounds around a house.
IV.Transportings and hoisting dry, should the whole hoisting up, not have to disassemble, the hoisting up steel wire should put in the machine four hoisting hole (or equipment both sides main axle).
