Specific embodiment
The following is specific embodiments of the present invention, and is further described in conjunction with attached drawing to technical solution of the present invention,
However, the present invention is not limited to these examples.
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
Shell 100 is equipped with preheating assembly 200, dry component 300 and heating component 400 in a housing 100.
Feed pipe 110 is installed for feeding on shell 100.
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
It is rolled on sieve plate 210.It opens up roller 220 to be arranged above sieve plate 210 comprising shaft 221 and the exhibition body being socketed in outside shaft 221.
The outer surface for opening up body and the tube wall of feed pipe 110 are tangent and tangent with the upper surface of sieve plate 210.Meanwhile in casing 100 and 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 connect by traction rope 232 with winding roll 231 respectively again, enable shaft 221 in traction electric machine
230 and traction rope 232 drive under slided in sliding slot 120.When shaft 221 is slided, exhibition body generates it by sieve plate 210
Frictional force enable exhibition roller 220 uniformly to grind the material of the upper surface of sieve plate 210 to rotate.
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 the arch section after exhibition roller 220 and the lower tube wall point of contact of feed pipe 110, draw simultaneously
Motor 230 drives exhibition roller to roll, and sodium pyrosulfite material is carried out from being pressed into dry component 300 in the sieve pore of sieve plate 210
It is dry.
Dry component 300 includes main shaft 310 and spirals about the spiral drying section 320 on main shaft 310, and spiral is dry
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
It is also separately installed with temperature detector 330 on 100 shell wall of casing that both ends are connected, for detecting 300 front and back two of dry component
Partial temperature difference.Temperature at 320 sharp end of spiral drying section should be not more than 150 DEG C, to prevent sodium pyrosulfite product from becoming
Property.
Heating component 400 generates on 100 shell wall of casing above 320 sharp end of spiral drying section of taper
Heat is most of to be transmitted to round butt end from the sharp end of spiral drying section 320, so that generating temperature ladder on spiral drying section 320
Degree.Fraction heat loss rises in preheating assembly 200, to preheat to material.
Heating component 400 includes air inlet pipe 410, heating member 420 and escape pipe 430, is equipped with air mistake in air inlet pipe 410
Filter 411, for filtering air in impurity and can be to the gas that sodium pyrosulfite product has an impact, so that in back tender
In skill, sodium pyrosulfite product will not be easily polluted by the external foreign matters.430 tube wall of escape pipe is along the tangent to helix direction of 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 limit plates 500, two pieces of limit plates are installed between preheating assembly 200 and dry component 300
500 one end passes through reset spring 510 and connect with 100 shell wall of casing, forms feed inlet between two pieces of 500 free ends of limit plate
520, and feed inlet 520 be located at taper spiral drying section 320 circle butt end top, thus 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, for the sodium pyrosulfite product for finally reaching dry requirement to be discharged.
The operation principle of the present invention is that: when sodium pyrosulfite product is fed from feed pipe 110, due to feed pipe 110
Tube wall and exhibition roller 220 are tangent, after sodium pyrosulfite product can be along exhibition roller 220 and the lower tube wall point of contact of feed pipe 110 after entering
Arch section falls, while traction electric machine 230 drives shaft 221 to slide in sliding slot 120, opens up roller 220 due to 210 pairs of sieve plate
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
It is paved with sieve plate 210, on the other hand by sodium pyrosulfite material from the limit plate 500 being pressed into the sieve pore of sieve plate 210 below.
Meanwhile and since heating component 400 is by air heating, thermal current is transmitted in shell, part hot gas passes through limit plate 500
Rising passes to sieve plate 210 and exhibition roller 220 with certain temperature, to carry out to a certain degree to the material on sieve plate 210
Preheating.
When no-load, the feed inlet 520 between two pieces of 500 free ends of limit plate is just engaged, when limit plate 500 by
When the pressure effect of the material fallen in its 210 sieve pore of upper sieve plate, the free end of limit plate 500 is moved down, to open feed inlet
520, so that material enters in dry component from the top of the circle butt end of cone-type spiral drying section 320.After material enters, multiple
Feed inlet 520 is closed again under the action of position paralysis 510, reaches sealing effect, prevents scattering and disappearing for most of heat.
It is lower 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, to be heated step by step, and due to the peptizaiton of spiral, material is obtained
To breaing up, to equably be dried.
320 sharp end of spiral drying section and the dry sodium pyrosulfite material finished are finally advanced to below sharp end
The discharge port 130 opened up is discharged.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
