Embodiment
It is below the specific embodiment of the present invention, and technical scheme is further described with reference to attached drawing,
But the present invention is not limited to these embodiments.
A kind of sodium pyrosulfite drying machine, it is as shown in Figure 1 and Figure 2, this to include dedicated for the drying machine of sodium pyrosulfite
Housing 100, is provided with preheating assembly 200, dry component 300 and heating component 400 in a housing 100.
Feed pipe 110 is installed on housing 100 to be used to feed.
Preheating assembly 200 includes sieve plate 210, exhibition roller 220 and traction electric machine 230, and traction electric machine 230 drives exhibition roller 220 to exist
Rolled on sieve plate 210.Exhibition roller 220 is arranged on the top of sieve plate 210, it includes shaft 221 and the exhibition body being socketed in outside shaft 221.
Outer surface and the tube wall of feed pipe 110 for opening up body are tangent and tangent with the upper surface of sieve plate 210.Meanwhile in casing 100 with turning
Sliding slot 120 is offered on two vertical shell walls of axis 221, the both ends of shaft 221 are separately mounted in sliding slot 120, and sliding slot 120 can
Support exhibition roller 220, and the shaft 221 for opening up roller 220 can move in sliding slot.Winding roll is installed on 230 output shaft of traction electric machine
231, the both ends of shaft 221 are connected by traction rope 232 with winding roll 231 respectively again so that shaft 221 can be in traction electric machine
230 and traction rope 232 drive under slided in sliding slot 120.When shaft 221 is slided, exhibition body is subject to sieve plate 210 to produce it
Frictional force, so as to rotate so that exhibition roller 220 can uniformly grind sieve plate 210 upper surface material.
It is burnt since 110 tube wall of feed pipe and exhibition roller 220 are tangent when sodium pyrosulfite product is fed from feed pipe 110
Sodium sulfite product can fall after entering along exhibition roller 220 and the arch section behind 110 times tube wall point of contacts of feed pipe, draw at the same time
Motor 230 drives exhibition roller to roll, and sodium pyrosulfite material is pressed into dry component 300 from the sieve aperture of sieve plate 210 and is carried out
It is dry.
Dry component 300 includes main shaft 310 and spirals about the spiral drying section 320 on main shaft 310, spiral drying
The section in portion 320 is taper.Motor 340 is connected with after main shaft 310, for controlling the rotation of main shaft 310.Meanwhile in main shaft 310
Temperature detector 330 is also separately installed with 100 shell wall of casing that both ends are connected, for detecting two before and after dry component 300
Partial temperature difference.Temperature at spiral 320 sharp end of drying section should be not more than 150 DEG C, to prevent sodium pyrosulfite product from becoming
Property.
Heating component 400 is positioned on 100 shell wall of casing above 320 sharp end of spiral drying section of taper, what it was produced
Heat is most of to be delivered to round butt end from the sharp end of spiral drying section 320 so that temperature ladder is produced on spiral drying section 320
Degree.Fraction heat, which scatters and disappears, to be risen in preheating assembly 200, to be preheated to material.
Heating component 400 includes air inlet pipe 410, heating member 420 and air outlet pipe 430, and air mistake is provided with air inlet pipe 410
Filter 411, the impurity being used in air filtering and the gas that sodium pyrosulfite product can be had an impact so that in back tender
In skill, sodium pyrosulfite product will not be easily polluted by the external foreign matters.Tangent to helix direction of 430 tube wall of air outlet pipe along spiral drying section 320
If so that the air after heated part 420 heats enters in dry component 300 along the direction of spiral rotating.
Specifically, two pieces of limiting plates 500, two pieces of limiting plates are installed between preheating assembly 200 and dry component 300
500 one end is connected by resetting spring 510 with 100 shell wall of casing, and feed inlet is formed between two pieces of 500 free ends of limiting plate
520, and feed inlet 520 be located at taper spiral drying section 320 justify butt end top so that define sodium pyrosulfite product into
Enter the position of dry component 300.
Discharge port 130 is offered on casing 100, discharge port 130 is located under the sharp end of the spiral drying section 320 of taper
Side, the sodium pyrosulfite product of dry requirement is finally reached for discharging.
The present invention operation principle be：When sodium pyrosulfite product is fed from feed pipe 110, due to feed pipe 110
Tube wall and exhibition roller 220 are tangent, and sodium pyrosulfite product can be along after opening up roller 220 and 110 times tube wall point of contacts of feed pipe after entering
Arch section falls, while traction electric machine 230 drives shaft 221 to be slided in sliding slot 120, since sieve plate 210 is to exhibition roller 220
Frictional force, exhibition roller 220 are rotated, so that exhibition roller 220 rolls on sieve plate 210, the rolling process is on the one hand by material
Sieve plate 210 is paved with, is on the other hand pressed into sodium pyrosulfite material from the sieve aperture of sieve plate 210 on limiting plate 500 below.
Meanwhile and since heating component 400 is heated by air, thermal current is delivered in housing, part hot gas passes through limiting plate 500
Rising passes to sieve plate 210 and exhibition roller 220 with certain temperature, so as to be carried out to a certain degree to the material on sieve plate 210
Preheating.
During no-load, the feed inlet 520 between two pieces of 500 free ends of limiting plate just engages, when limiting plate 500 is subject to
During the pressure effect of the material fallen in its 210 sieve aperture of upper sieve plate, the free end of limiting plate 500 moves down, so as to open feed inlet
520 so that the top that material justifies butt end from cone-type spiral drying section 320 enters in dry component.After material enters, multiple
Feed inlet 520 closes again under the action of position paralysis 510, reaches sealing effect, prevents scattering and disappearing for most of heat.
It is relatively low from temperature under the rotation progradation of the spiral drying section 320 of taper after material enters dry component 400
Circle butt end be advanced to the higher sharp end of temperature, so as to be heated step by step, and since spiral peptizaiton, material obtain
To breaing up, so as to equably be dried.
Finally it is advanced to spiral 320 sharp end of drying section and the dry sodium pyrosulfite material finished is below sharp end
The discharge port 130 opened up is discharged.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, but without departing from spirit of the invention or beyond the scope of the appended claims.
