Description

Drying device
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.

The direction rotary shaft 5a of a side in two rotary shafts 5 mobile towards the side rotary shaft 5b of another party at an upper portion thereof On rotated.In addition, the rotary shaft 5b of another party rotates on the direction of the rotary shaft 5a far from a side at an upper portion thereof.It changes Sentence is talked about, and two rotary shafts 5 are rotated when from 1 direction of axes O to same direction.
The blade 6b of blade 6a set on the rotary shaft 5a of a side and rotary shaft 5b set on another party be formed as from With towards wedge shape that width narrows in front of direction of rotation when radial outside is observed.
In addition, blade 6 adjacent on 1 direction of axes O has on the side 18 as the inclined surface for forming wedge shape each other There is mutually opposed opposed portion 10 on 1 direction of axes O.In addition, blade 6 adjacent on 1 direction of axes O is configured to each other Mutual phase shifting in the circumferential direction of rotary shaft 5.More specifically, the blade 6 of adjacent level is configured on 1 direction of axes O Phase shifting in circumferential direction, and be configured on 1 direction of axes O become same phase every level-one.
Blade 6 has the two sides scraping plate part 11 outstanding to 1 direction of axes O.Scraping plate part 11 has respectively in direction of rotation First scraping plate part 13 and second scraping plate part 15 of the upper configuration in different location.As shown in FIG. 2 and 3, set on the rotation of a side The blade 6a of axis 5a has the scraping plate part 11 including the first scraping plate part 13a and the second scraping plate part 15a, set on the rotary shaft of another party The blade 6b of 5b has the scraping plate part 11 including the first scraping plate part 13b and the second scraping plate part 15b.
These first scraping plate parts 13 and the second scraping plate part 15 are respectively to the prominent part formed in the two sides in 1 direction of axes O Have towards the face 16,17 in front of direction of rotation.These first scraping plate parts 13 and the second scraping plate part 15 can utilize direction rotation Treated object P existing between jam blade 6 adjacent on 1 direction of axes O is carried out in face 16,17 in front of direction.
Fig. 4 is the locally figure of planar development rotary shaft 5 and blade 6 in the axial direction.In Fig. 4, paper or so Direction is the circumferential direction of rotary shaft 5, and paper up and down direction is 1 direction of axes O of rotary shaft 5.In addition, using the arrow in Fig. 4 come Indicate the direction that rotary shaft 5 rotates.
As shown in figure 4, multiple blades 6 are formed as respectively circumferentially, the front and rear portion in direction of rotation has The opposed portion 10 opposed with blade 6 adjacent on 1 direction of axes O.Moreover, multiple blades 6 are distinguished in the rear end of opposed portion 10 Has scraping plate part 11.More specifically, has the first scraping plate part 13 in the rear end 12 of the direction of rotation of blade 6, than first Middle part 14 of the scraping plate part 13 in front of direction of rotation has the second scraping plate part 15.Second scraping plate part 15 is configured to and adjacent leaf The configuration of first scraping plate part 13 of piece 6 is corresponding.
First scraping plate part 13 and the second scraping plate part 15 are formed towards the opposed of adjacent blade 6 on 1 direction of axes O Portion 10 is stretched out.Moreover, the second scraping plate part 15 with the first scraping plate part 13 relative to adjacent blade 6 on 1 direction of axes O phase Mutual end mode opposite each other is configured in same phase.
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.
