Abstract
For manufacture of solid fuels by solidifying processing-object materials containing plastics, waste paper and waste wood, the processing-object materials are inputted through an input port 12 are subjected to water injection so that their water content becomes 15 wt% or more, preferably 20 wt% or more, and then kneaded, compacted and extruded in three turns or less, being extruded from molding nozzles 53 of an end face plate 5. The water injection is performed by a water injection nozzle 31 from the input port 12 into a casing 11. Opening and closing of a solenoid valve 33 interposed on a water injection pipe 32 adjoining the water injection nozzle 31 is controlled based on a signal S1 derived from a temperature sensor 55 provided at a molding nozzle 53 of the end face plate. Such disadvantages as inflammation due to excessively high temperatures of the processing-object materials or worsened shape retention of solidified materials due to excessively low temperatures of the processing-object materials can be prevented.

In addition, by with well heater 54 at the thickness direction of end plates 5 configuration two row, thereby even as described later with mounting face under situation about changing between the two sides in the table, the heat characteristic of object being treated is changed hardly.In addition, even a well heater 54 of thickness direction breaks down, also can therefore, can improve the reliability of heating function by another well heater 54 heating object being treateds.
Control part C is based on the action of controlling the magnetic valve 33 of water injection pipe from the signal SI of temperature sensor 55.In detail, control part C is at the signal S1 that receives from temperature sensor 55, when the temperature that detects object being treated has surpassed 120 ℃, control signal W to be sent to magnetic valve 33, the magnetic valve 33 that has received control signal W is opened and carry out water filling in housing 11.Thus, the temperature of the object being treated in the housing 11 reduces, and can prevent the troubles such as generation of on fire or toxic gas.On the other hand, control part C is at the signal S1 that receives from temperature sensor 55, and the temperature that detects object being treated is when being lower than 120 ℃, and W sends with control signal, and magnetic valve 33 cuts out, and stops to carry out in housing 11 water filling.Like this, carry out water filling control, the temperature of object being treated is controlled at roughly more than 100 ℃ and in the temperature range below 140 ℃ by utilizing temperature sensor 55.
In addition, the reference temperature and the temperature range of carrying out the control of this magnetic valve 33 can be carried out suitable change according to the formation and the amount of moisture of object being treated.For example, amount of moisture at object being treated is approximately under the situation of 15wt%, as mentioned above, be controlled at more than 100 ℃ and the temperature range below 140 ℃, on the other hand, the amount of moisture of object being treated is under the above situation of 20wt%, is controlled at more than 120 ℃ the temperature of object being treated and the temperature range below 180 ℃.Thus, by in the process of screw shaft 2 mixing compression object being treateds, the heating by following compression and the heating of well heater can prevent the trouble that object being treated is on fire.In addition, in the process of mixing compression object being treated, moisture can be made heating steam and suitably remove, can prevent act as a fuel combustible reduction when using of cured article.
In addition, the closing control of magnetic valve 33 there is no need and must carry out according to the detected temperatures of temperature sensor 55.For example, also can carry out following control, when opening magnetic valve 33, pick up counting, when having passed through the specified time, close magnetic valve 33.
In addition, above-mentioned control part C starts control heater 54 when the start signal S2 of the starting that receives the instruction fixing the handles device.Thus, will when finishing, previous motion remain in the object being treated fusion in the shaping nozzle 53, even after starting just, also the object being treated after handling promptly can be discharged from shaping nozzle 53.
In addition, when above-mentioned control part C receives the stop signal S3 that the instruction fixing the handles device stops, control signal is sent and magnetic valve 33 is opened to magnetic valve 33, in housing 11, carry out water filling.When this magnetic valve 33 is opened control, pick up counting, in experience during the specified time, control signal W sent and closed electromagnetic valve.Then, the driving of the screw shaft 2 that electric motor M is driven stops, and finishes the running of fixing the handles device.Thus, can shut down with the object being treated remollescent state in the housing 11.Therefore, can prevent when next time running begins trouble such as difficulty, and the troubles such as load increase of electric motor M because the driving of the object being treated screw shaft 2 that has solidified becomes.

Fig. 7 is the front view that is illustrated in the pad 8 of clamping between the flange 13 of above-mentioned end plates 5 and housing.This pad 8 has the physical dimension roughly the same with the physical dimension of end plates 5, when overlapping with end plates 5, in the position that links to each other with communicating pores 5a communicating pores 8a is set.In the central authorities of pad 8 8b of cutting-out portion of Pear-Shaped is set, the 8b of this cutting-out portion with the planar portions 23d of triple helical body opposed and downcut than and describe the bigger scope in zone of rotational trajectory.This pad 8 is held between the flange 13 of above-mentioned end plates 5 and housing, makes bolt insert the communicating pores 5a of go side panel and the communicating pores 8a of pad, end plates 5 and pad 8 are fixed in flange.By using this pad 8, the gap between the planar portions 23d of the triple helical body of adjustable side panel 5 in the face (mounting face) of a side of housing 11 inside and the housing 11 accurately.In addition, originally pad 8 is installed in running, on the other hand, by removing pad 8 after the abrasion that produce specified amount in running, even after pad is removed, also can be before the abrasion that produce specified amount use side panel 5, therefore, the use side panel 5 chronically.
Above-mentioned end plates 5 have a plurality of bolt hole 5b, the 5b... of installation end panel side metalwork 51a in two sides.In addition, end plates 5 two sides in table is formed with the flange 53a of shaping nozzle and the stage portion 52a that outlet orifice 52 cards end.Thus, for end plates 5, replaceable between the two sides in the housing 11 inner mounting faces of installing are being shown.Therefore,, use, therefore, can access long work-ing life owing to its two sides can be changed though that end plates 5 bear the high compression forces wear loss of the object being treated that triple helical body 23 causes is bigger.Especially, by using pad 8, the work-ing life of extended end panel 5 effectively.
The fixing the handles device of above-mentioned formation is following to move.
At first, the starting switch of fixing the handles device is pressed entry into service by the operator.Follow pressing of starting switch, start signal S2 is exported to control part C from the controlling organization of fixing the handles device.Received the well heater 54 supply capability Ps of the control part C of start signal S2, carried out the preparation heating of end plates 5 to end plates.Will residual and solidified object being treated fusion in nozzle 53 when thus, Shang Yici running is finished.
Then, under the control of controlling organization, electric motor M starts, and the revolving force of electric motor M is transmitted to turning axle 70 via drive motor T, speed reduction unit R and shaft coupling 4.Pair of rotary shafts 70 in the wheel box 3 is rotation inversely mutually, and a pair of screw shaft of installing at the drive shaft 72 that links to each other with turning axle 70 2,2 rotates in housing 11 mutually inversely.A pair of screw shaft 2,2 sees towards the inboard of width on the plane and rotates, and, the front see from down direction rotation.Preferred screw shaft 2 with 30rpm (rpm) above and lower speed rotation that 60rpm is following.
In addition, starting blower B begins exhaust in housing 11 via the passage that is connected in venting port 14.
Like this, after the driving of processing main body 1 begins, begin to drop into object being treateds from the input port 12 of housing 11.The mixture of non-melts such as melts such as the preferred plastics of object being treated and paper.Especially for object being treated, preferably its ratio that constitutes thing be melts at 40wt% (weight ratio) and between below the above 60wt%, and non-melts is more than the 30wt% and below the 40wt%.In addition, other formation thing is as long as for example be water and the such rubbish based on water of the rubbish that contains moisture.
In housing 11, by the object being treated that 21 clampings of a pair of first spirochete are dropped into, it is carried out mixing, and send to second spirochete, 22 sidesways reliably by the holding force of brute force.Second spirochete 22 imports object being treated in the treatment chamber that forms between this second spirochete 22 and liner 15, carry out the mixing of object being treated and compression.The object being treated that is imported in the above-mentioned treatment chamber is carried to end plates 5 sides by the spinning movement of above-mentioned second spirochete 22, carried out mixing simultaneously and compression, therefore, can effectively prevent the adverse current of object being treated.Then, triple helical body 23 imports object being treated in the treatment chamber that forms between this triple helical body 23 and liner 15, and carries out further mixing and compression.First, second and third spirochete 21,22,23 increases ground in order and forms axial region 21a, diameter D1, the D2 of 22a, 23a, D3, increase ground and form the screw-blade 21b of portion, spacing P1, the P2 of 22b, 23b, P3, increase ground and form the screw-blade 21b of portion, the thickness T 1 of 22b, 23b, T2, T3, therefore, the troubles such as reduction that do not have the engaging-in and density of object being treated can mixing effectively and compression object being treated.
In addition, first, second and third spirochete 21,22,23 can make object being treated produce the heat of compression and heat of friction by successively big force of compression being applied and carries out mixingly to object being treated effectively.Thus, can make the melts fusions such as for example plastics that comprise in the object being treated effectively.This heat of compression and heat of friction as mentioned above, the melts that comprises in object being treated is more than the 40wt% and below the 60wt%, and non-melts can generate under the situation more than the 30wt% and below the 40wt% effectively.Like this, can utilize the heat of compression of object being treated and heat of friction to dissolve melts fully, therefore, not need as at present, well heater to be set in the side of housing 11.That is, carry out boosting, can dissolve the melts of object being treated fully by the well heater 54 that utilizes end plates 5.
In the fixing the handles device of present embodiment, by first heating to the mixing and compressed action and the well heater 54 of triple helical body 21,22,23, the temperature of object being treated rises efficiently.At this, because the formation of 12 object being treateds that drop into changes from the input port, or the ratio increase of non-melts etc., temperature can sharply rise sometimes.Under this situation, when the temperature of utilizing temperature sensor 55 to detect object being treated had surpassed 120 ℃, based on the signal S1 from this temperature sensor 55, control part C output control signal C opened magnetic valve 33.Thus, carry out following control, promptly supply with water from water filling nozzle 31 in housing 11, the temperature of object being treated reduces, and the temperature of the object being treated of discharging from the outlet orifice 52 of end plates is become more than 140 ℃.Thus, can prevent the trouble that object being treated that high temperature causes is on fire and cause unburnt trouble, and produce the trouble of toxic gases such as chlorine.
After in housing 11, carrying out water filling, utilize the heat of compression and the heat of friction of object being treated, or utilize the heat of well heater 54, moisture evaporation is generated water vapour.Especially near well heater 54, and around the big triple helical body 23 of the force of compression of object being treated, generate high temperature, highly compressed water vapour.Should be by blower B with venting port 14 sucking-offs of water vapour from the both sides of the input port 12 that is formed at housing, and outside the room, discharge.Thus, can effectively prevent to become unusual high pressure in the housing 11, make the troubles such as oil sealing breakage on every side of being located at turning axle 70.In addition, carry out exhaust in the housing 11, thus, can reduce the degree of the movement disorder that attracts at 12 object being treateds that drop into, can carry out exhaust with good efficiency from the input port from the venting port 14,14 of the both sides that are arranged at above-mentioned input port 12.In addition, in housing 11,, therefore, can prevent to sneak into troubles such as water vapour from the object being treated that the shaping nozzle 53 of the outlet orifice of end plates is discharged towards carrying out exhaust with the direction reverse direction of transferring object being treateds by screw shaft 2,2.
When carrying out water filling in housing 11, receive when being lower than 120 ℃ from the signal S1 of temperature sensor 55 and the temperature that detects object being treated, control part C output control signal W closes magnetic valve 333 and stops water filling.Thus, can prevent object being treated cooling and make the troubles such as conformality reduction of cured article.
In addition, the reference temperature that control part C will control the object being treated of magnetic valve 33 is set at 120 ℃, opens control when surpassing reference temperature, carries out closing control when being lower than reference temperature, but also can set a plurality of reference temperatures, and change aperture interimly in each reference temperature.As long as importantly can come the water injection rate of Automatic water-filling nozzle 31, the temperature of object being treated is controlled in the predetermined temperature range gets final product by control.
In addition, control part C also can be based on the signal S1 from temperature sensor 55, and control makes the temperature of object being treated be in the specified temperature scope to the delivery of well heater 54 thus.
The object being treated that imports triple helical body 23 and compressed by high pressure is extruded into bar-shaped from the shaping nozzle 53 of end plates 5 under melts fused state.The object being treated that is extruded into rod-like is cut to specified length by stapling machine 6, and falls into the hopper that is disposed at downside and reclaim.The bar-shaped object being treated that is cut to specified length is followed temperature decline and melts is solidified, and becomes solid-state regenerated fuel.Do the solid-state regenerated fuel that obtains like this and have the thermal value of 5000～6000cal/g, can be used as fuel utilization.
When the running of fixing the handles device stopped, the control part C that has received stop signal S3 sent control signal W and magnetic valve 33 is opened, and carried out water filling in housing 11.Carry out this magnetic valve 33 open control in, pick up counting, when timing begins through 3 minutes, close magnetic valve 33.Afterwards, make electric motor M stop and stopping the rotation of screw shaft 2.By shutting down under the object being treated remollescent state in housing 11, can prevent when next time running begins because the object being treated that has solidified causes trouble, and the trouble that increases of the load of electric motor M of the driving difficulty of screw shaft 2.In addition, the time that receives stop signal S3 and carry out water filling was not limited to 3 minutes, can carry out suitable variation according to the constituent material of object being treated etc.
