The specific embodiment
With the rotary steam drying machine is example, and to the horizontal type spin-drier relevant with the present invention, seeing figures.1.and.2 is further detailed.
Rotary steam drying machine of the present invention, in rotating cylinder 10, by the moistening powder or the particle powder that drop into from the loading port of rotating cylinder one end face are contacted with the heating tube 11 that is heated by heat-carrying thing (for example heating steam), when carrying out drying, because rotating cylinder 10 is configured to downward-sloping state, can move to the other end continuously in order, and discharge from outlet.Described heating tube 11 disposes many with axis parallel between the end plate at the both ends of described rotating cylinder 10, the steam of supplying with as the heat-carrying thing to these heating tubes 11 carries out heat exchange with the thing that is dried in rotating cylinder 10.
The thing that is dried for example, is loaded in the rotating cylinder 10 by dropped channel from loading port.One end of described dropped channel is inserted in the rotating cylinder 10 by the peristome that is located at loading port side end panel centre, makes from the thing that is dried of loading port input to rely on gravity to be slipped in the rotating cylinder 10 in dropped channel.Can be connected with it with respect to fixing dropped channel rotating cylinder 10 with rotating freely.This pack into the part mode, except that take with Fig. 3 the same manner, other well-known mode etc. can both adopt.
The rotating mechanism of spin-drier, except that with Fig. 3 same way as, other known mode can both adopt.
On the other hand, as depicted in figs. 1 and 2, in another distolateral (dry thing discharge side) of rotating cylinder 10, at the central part of outlet side board 12, the dry thing export department 20 have to the peristome 21,22 of other end direction (Fig. 1's is right-hand) opening is set integratedly.
Relative with this export department 20, be provided with respectively the discharge case 31 that is communicated with peristome 21,22 with dry thing outlet 31A, and have in rotating cylinder 10, be blown into gas be blown into mouthful 32A send into case 32.
As gas G, can select suitable gas such as air and inert gas, it is blown into pressure and preferably pressurizes to prevent outer gas cut from going into and be blown into.At last, from the entrance side of the material that is dried, for example discharge from described 122.
Have again, have the next door 23 that is separated into inboard and the outside in export department 20, the outside in this next door 23 becomes sends passage, in an embodiment, send on the passage facing to peristome 21 at this and to be provided with the blade of sending dry thing and to be provided with propeller type blade 24 in an embodiment.For example, the blade with gate shape etc. replaces the propeller type blade also can.Blade is not set, and it also is possible that list is sent passage with space formation.
Described discharge case 31 sees to have the fire balloon shape that similar bottom narrows down from the side.And, between the cylindrical of discharging case 31 and export department 20, accompany sealing 41, reach the purpose of sealing by it.
Case 31 is relative with discharging, and the top of sending into the 32B of top cylinder portion of case 32 and discharging case 31 connects, and its underpart becomes the divider wall parts 32C of cylinder (more specifically be exactly at Fig. 1 left have narrow down a little coniform) substantially.
Thus, send into case 32 and be separated with discharge case 31, the left end of divider wall parts 32C is in the state that inserts in the peristome 21.
On the other hand, discharge case 31, in divider wall parts 32C, and to next door 23 in, extend and the steam suppling tube 61 of the steam S that faces mutually with the next door and the steam passage and rotating cylinder 10 integral body settings that coaxial condensed water discharge pipe 61 constitutes by passing.
Steam suppling tube 61 and be communicated with at the inlet head of the heating tube 11 of end plate portion 12, condensed water discharge pipe 62 and be communicated with at the outlet head of the heating tube 11 of end plate portion 12.And steam suppling tube 61 and condensed water discharge pipe 62 are connected with steam suppling tube 64 and condensed water discharge pipe 65 respectively by rotary connector 63.These communicating pipes yet rely on support component 66 to support except that the function that has as the support component of steam passage.
In addition, rely on the purpose that the sealing 92 that clips between the cylindrical of discharging case 31 and condensed water discharge pipe 62 reaches sealing.
In relevant mode, as shown in Figure 1, gas G directly sends into the inboard the inside in next door 23 from sending into case 32.
On the other hand, the rotation of accompanying rotation tube 10 is because of propeller blade blade 24 also encloses the axle center rotation, dry thing leading surface is sent to the transmission effect of peristome 21 propeller blade blades 24, discharge from peristome 21, and then rely on deadweight to fall into and discharge in the case 31, outside its outlet 31A discharge machine.Peristome 21 and peristome 22 relies on divider wall parts 32C to be actually to separate mutually, so can not be subjected to being blown into the influence of gas, can successfully discharge.
Have again, rotating cylinder 10, for example, length be 10m to 30m, because of the internal temperature height, expand and shrink axially can producing of rotating cylinder 10.Contrast is discharged case 31 and is sent into case 32 and rotary connector 63 etc., fixes with respect to stand 50.Discharge case 31 and fix, send into case 32 and discharge case 31 is fixed with the relative stand 50 of integral way with respect to stand.
Close the position in the export department 20 of rotating cylinder 10 and the iron chains of discharging case 31, rely on and keep sealing, also have as the sealing 91 of seal means, rely on and the cylindrical of condensed water discharge pipe 62 between the sealing 92 that clips keep sealing.Produce so-called competition sometimes with this seal means, around the axle center rotation, be absorbed in defective mode when being sealed with because of discharging case 31 (and comprise send into case 32).Also have, under the situation of the confining force that only relies on steam suppling tube 64 and condensed water discharge pipe 65, it is unstable that rotary connector becomes, and the problem of bearing class serious wear takes place sometimes.
On the other hand, make and discharge case 31 (sending into case 32), and rotary connector 63 etc., with respect to as the stand 50 on basis with rigid state fixedly the time, their accompanying rotation tubes 10 are in axial expansion and contraction and be out of shape, thereby the distortion of sealing device and breakage etc. can take place.
Therefore, in embodiment, and stand 50 between rely on the double deformation mechanism 70 that prevents of braking to support rotary connector 63, rely on braking to hold concurrently and anti-distortion mechanism 80 supports and discharges case 31.
Brake double deformation mechanism 70 and the double deformation mechanism 80 that prevents of braking of preventing and be actually same structure, therefore, only just brake the double deformation mechanism 70 that prevents and elaborate, this mechanism has: in the side of rotary connector flange 73 is arranged, between 73 back shaft 72 is arranged; Support component 71; On stand 50, be fixed with bracket 74, the rotation back shaft 75 of support is arranged on bracket 74.The top loose running fit of support component 71 is in described back shaft 72, and its underpart is that hinge is supporting with rotation back shaft 75.
Brake the double deformation mechanism 70 that prevents and just can understand that it can prevent that rotary connector from centering on the rotation in axle center from the diagram relation as the effect of auxiliary rod.Also have, in the axial expansion and the contraction of accompanying rotation tube 10, rotary connector 63 is also when moving axially as shown in Figure 1, support component 71, its underpart is because of being connected with the rotation back shaft 75 with hubbing structure, so along with expanding and shrink the tiltable certain angle, thereby can absorb distortion.
Discharge case 31 also with the double deformation mechanism 80 that prevents of braking, can prevent around the rotation in axle center as a same reason and will be out of shape absorption.
Effect of the present invention: as mentioned above, use the present invention, have the gas that can prevent and in rotating cylinder, be blown into and interweave, can make the stable advantage of discharging of dry thing again.
