The application be the applying date be on May 04th, 2016, application No. is 201610289262.3, it is entitled " dry
The divisional application of the patent application of device ".
Technical field
The present invention relates to one kind to locate this while carrying the treated objects such as waste along defined carry direction
Manage the drying device of object heat drying.
Background technique
The treated objects such as various biological substances (biomass), waste (sludge) contain a large amount of moisture, therefore make sometimes
Implement the drying process based on heating with drying device.
As drying device, such as it has been known that there is following drying device, have shell, the In that section is a substantially U-shaped
Two hollow shafts that the inside of shell rotates in the opposite direction each other and in fan-shaped that the periphery of the hollow shaft arranges etc.
Empty blade.
Drying device has the shell for being formed towards the reduction of carry direction downstream side.It is formed in the upstream end of shell useful
In the supply mouth of investment treated object.The processed of the treated object put into from supply mouth can be accommodated by being formed with inside the housing
Object accommodating space.The treated object for being contained in treated object accommodating space is installed in the periphery for the hollow shaft that can be rotated on one side
Blade stirring, gravity caused by the inclination by shell is gently moved towards carry direction downstream side on one side.
The heating such as steam, conduction oil, hot water is directed respectively into the inside, the inside of blade and the inside of shell of hollow shaft
Medium.Therefore, treated object is heated when mobile to carry direction downstream side while being stirred, such as makes state change
For liquid, argillaceous, bulk, granular, powder shaped, with the state of plastochondria or powder after drying from being configured at outer casing back
Sludge outlet discharge.
In drying device, treated object and thermal conductive surface are carried out while the heating of progress treated object, dry sometimes
The chance of contact reduces and can not obtain enough drying properties.In this regard, proposing following drying device (referring for example to patent
Document 1): pass through the heat medium temperature or flow for making to have two hollow shafts of spiral helicine stirring blade mutual in outer peripheral surface
With difference, be consequently formed the dried object supplied to the inside of drying device be attached to a side hollow shaft thermal conductive surface without attached
In another party hollow shaft thermal conductive surface situation, in addition, by striking off the hollow shaft in a side by the hollow shaft of another party
The treated object of upper attachment, to have mixing effect.
In addition, being configured at spaced intervals on the axes O direction of rotary shaft 5 as drying device as shown in figure 9, having
There is the structure of the blade 6 of the stirring of the substantially fan-shaped radially extended along the rotary shaft 5.The drying device is set as, and is set to
Each blade 6 of two rotary shafts 5 is configured at spaced intervals in a manner of alternately engaging on axes O direction, each 5 direction of rotary shaft
Inside and rotation reversely with each other.
Here, the treated objects such as downflow sludge P1 carries out dehydration procedure before supplying to drying device mostly, big absolutely
Under most of the cases, high-molecular coagulant is put into treated object in the dehydration procedure.High-molecular coagulant, which is contained in, to be located
Object is managed, thus the viscosity of treated object P1 improves, such as in the ranges near moisture content is more than 50~60%, viscosity becomes most
It is high.In other words, liquid treated object is heated in the inside of drying device and moisture content gently reduces and it is dry to become
During dry powder shaped, state as the high raw rubber of viscosity is temporarily become.
Liquid, powder shaped treated object P1 can be tilted to carry direction because of shell 3 and be stirred treated object P1
It mixes and is easy to move in carry direction.In addition, claylike treated object P1 is in each blade 6 in the low processed material of viscosity
The position of engagement is sheared by opposed blade 6 and becomes fritter, therefore the fritter can pass through adjacent 6 mutual, blade
Gap, and then moved between the blade 6 of next stage downstream.
But in the case where the viscosity of treated object P1 height, bulk is formed between blade 6 due to its property sometimes.
In this way, can not generate when treated object P1 forms bulk and flow caused movement by squeezing.More specifically, treated object
P1 becomes state as the high raw rubber of viscosity, and in the middle part of drying device, treated object P1 becomes can not be from axes O
The bulk of degree mobile between adjacent blade 6 on direction.Then, as shown in Figure 10, if treated object P1 and rotation
Shaft 5, blade 6 continue to rotate together at this, can not carry out sometimes mobile by stirring and squeezing flowing bring.
As described above, if the movement of treated object P1 can not be carried out, subsequent quilt is blocked because of treated object P1
Processed material P1.As a result, the range for the treated object P1 being plugged increases, finally make in space all to be located by viscosity is high
Manage object P1 filling.In addition, in the case where carrying out continuous heating to treated object P1 in this state, the moisture content of treated object P1
It reduces and treated object P1 hardening.Moreover, if hard as the state and treated object P1 filled by treated object P1 in space
The state of change then stops because of over torque etc. rotary shaft 5.
In order to avoid above-mentioned phenomenon, in general, passing through in order to avoid the high treated object P1 of viscosity results in blockage as bulk
Keep the flow of treated object P1 sufficiently small relative to flow path cross-sectional area, so that subsequent treated object P1 be prevented to be plugged.

Patent document 1: Japanese Unexamined Patent Application 63-189776 bulletin
As the example of above-mentioned phenomenon, exists relative to the treated object containing more inorganic matter and largely put into high score
The case where sub- coagulating agent etc..Moreover, present inventor has found following result: for example in treated object by conscientiously studying
Solid under inorganic constituents containing ratio, that is, ash content containing ratio is higher and the very high situation of viscosity, to treated object
Extremely special flowing property and drying property are represented during being thermally dried.Above-mentioned special property refers to,
Under common common technical knowledge, it should be that viscosity is higher and rate of drying more reduces, but the feelings of the treated object in above-mentioned condition
Under condition, the more high rate of drying instead of viscosity more increase.This is because ash content containing ratio plays dominating role.
For the property of such treated object, even if in the case where reducing flow sufficiently, due to rate of drying
Fastly, therefore because drying sharply causes viscosity to be increased sharply, bulk is formed between the blades.In this way, the ash content in treated object contains
Rate increase and have very high viscosity in the case where, even if blade incision become bulk claylike treated object, also without
Method cuts off treated object and the appearance of bulk is kept persistently to rotate together in identical place with hollow shaft.Therefore, in order to anti-
The only mobile sluggishness of treated object, it has to further decrease the flow of treated object, therefore existing drops processing capacity significantly
Low such project.

Next, the heating and drying method for the treated object P that above-mentioned drying device 1 is carried out referring to Fig. 3, Fig. 5 into
Row explanation.It should be noted that treated object shown in appended drawing reference " P " is in liquid into shell 3 in Fig. 3, Fig. 5
Supply, be upstream side heated and moisture content reduce (more than 50%~60% left and right), in argillaceous and formation it is very high
Viscosity sludge.
Firstly, since rotary shaft 5a is rotated in the same direction with rotary shaft 5b, therefore the treated object P being present in slot 2
(in Fig. 3, illustration omitted) the adjacent blades 6a and blade 6a of rotary shaft 5a each scraping plate part 11a (the first scraping plate part 13a,
Second scraping plate part 15a) under the action of to being swept on the upside of direction of rotation.Then, treated object P remains in phase with the state of bulk
Between adjacent blade 6a.Then, treated object P is mobile to the side rotary shaft 5b around rotary shaft 5a.
On the other hand, blade 6b is by the rotation of rotary shaft 5b and from bottom to top by between adjacent blade 6a.Cause
This, each scraping plate part 11b (the first scraping plate part 13b, the second scraping plate part 15b) of blade 6b and blade 6b is to remaining in adjacent leaf
Treated object P between piece 6a cuts and collides with it.Then, the treated object P quilt between adjacent blade 6a is remained in
Blade 6b and the first scraping plate part 13b, the second scraping plate part 15b are swept upwards.Week of the treated object P from rotary shaft 5a as a result,
Disengaging is enclosed, is concomitantly moved around rotary shaft 5b with the rotation of rotary shaft 5b.At this point, the treated object P swept is because of shell 3
Tilt and fall into and enter blade 6b between the adjacent blade 6b in its carry direction downstream side.
The treated object P entered between these adjacent blade 6b on one side and the side 18 of blade 6b come into full contact with, one
While being relatively moved relative to each blade 6b to the rear of direction of rotation.Then, treated object P is configured on rear side of direction of rotation
The scraping plate part 11b (the first scraping plate part 13b, the second scraping plate part 15b) of blade 6b is pressed from 1 direction two sides of axes O, around rotary shaft 5b
And it is concomitantly moved with the rotation of rotary shaft 5b.
At this point, treated object P and the treated object P remained between rotary shaft 5b and slot 2 are integrally formed.Scraping plate part 11b
And then among the treated object P by remaining between rotary shaft 5b and slot 2, keep treated object P mobile to the side rotary shaft 5a.
Then, the blade 6a of rotary shaft 5a passes through the adjacent of rotary shaft 5b by the rotation of rotary shaft 5a from the top down
Between blade 6b, therefore, the treated object P of the side rotary shaft 5a is moved to by scraping plate part 11b, is present in adjacent blade
Treated object P between 6b is stirred by the blade 6a of rotary shaft 5a.More particularly, there are the treated objects between blade 6b
P cuts pressing by blade 6a from the top down, hence between rotary shaft 5a and slot 2.At this point, treated object P inclining because of shell 3
The tiltedly downstream side movement to the blade 6a of pressing treated object P, enters between adjacent blade 6a.Then, phase is entered
Treated object P between adjacent blade 6a repeats above-mentioned movement, is heated by shell 3, rotary shaft 5a, 5b etc., delays on one side on one side
It is carried towards downstream side on slow ground.In other words, treated object P alternately revolves around it axis 5a and rotary shaft 5b, from the axis
The motion track of the direction line O1 observation becomes such shape shown in the arrow in Fig. 5.
According to above embodiment, it is in adjacent rotary shaft 5a, 5b, on rotary shaft 5a because of the viscosity of treated object P
And in the case where being wound with the treated object P under the very high state of viscosity, it can utilize due to the rotation of rotary shaft 5b along week
Struck off to the blade 6b and scraping plate part 11b that move up circumferentially moved down because of the rotation of rotary shaft 5a it is processed
Object P.Then, make the treated object P being stripped off and rotary shaft 5b rotates together and falls into downstream side and to rotary shaft 5a sidesway
When dynamic, it can be stirred using the blade 6a set on rotary shaft 5a.
At this point, by being formed as the blade 6b set on rotary shaft 5b from radial outside with towards before direction of rotation
Side and wedge shape that width narrows, contacting efficiency when treated object P is swallowed between blade 6b and slot 2 improve, therefore can
Improve drying efficiency.
As a result, the treated object P struck off from rotary shaft 5a is made to fall into downstream side, can be more reliably prevented from processed
Blocking caused by the mobile delay of object P.
In addition, utilizing setting and toward each other opposed in each opposed portion 10 of adjacent blade 6 on 1 direction of axes O
Each scraping plate part 11 that portion 10 is stretched out assigns biggish resistance relative to the treated object P configured between adjacent blade 6
And prevent from carrying undesirable condition, it is able to maintain that contacting efficiency and does not cause stagnantly being operated for treated object P.
In addition, by configuring the mutual phase in the circumferential direction of rotary shaft 5 each other for blade 6 adjacent in the axial direction
Dislocation is opened, and is thus configured in the circumferential direction of rotary shaft 5 each other with by adjacent blade 6 on 1 direction of axes O as identical phase
The case where position, compares, and is able to suppress movement speed of the treated object P towards carry direction.That is, since flow path opening 9 is in axis
Without configuration in same phase on direction, therefore the movement speed of treated object P is slack-off, so as to prevent from becoming because of movement speed
Lead to dry the case where becoming inadequate fastly.
Further, since scraping plate part 11 is arranged opposite, therefore treated object P can be further reduced not by scraping plate part 11
Jam and the case where miss.
In addition, due to only with respect to have the blade 6 of the first scraping plate part 13 in direction of rotation backend arrangement and in adjacent leaf
The opposed portion 10 of piece 6 the second scraping plate part 15 of additional configuration, therefore can reduce treated object P's using simple structure
It is detained.
In addition, making adjacent rotary shaft 5a, 5b each other to same direction in multiple rotary shafts 5a, 5b of drying device 1
Rotation can prevent the blocking as caused by treated object P generated in the case where rotating round about.
