Description

PYROLYSIS GASIFIER INCLUDING AUTOMATED LOCKING APPARATUS}

The present invention relates to a pyrolysis gasifier comprising an automatic locking device.

Wastes such as household waste, industrial waste, etc. are treated in various ways. One of the waste disposal methods is to classify combustible waste, including organic matter, waste that can be used as biomass fuel, and polypropylene-based waste synthetic resin, pyrolyze it, and use the combustible gas generated through pyrolysis to drive a turbine. This is a method used to generate steam. If we use the gas generated by pyrolyzing combustible waste in a gasifier, we can alleviate the problem of global warming by reducing carbon dioxide emissions.

A conventional pyrolysis gasification furnace is configured so that the bottom door part can be moved up and down by a hydraulic cylinder. The bottom door part moved upward by this hydraulic cylinder seals the lower part of the cylinder. A device is provided to lock the bottom door and the barrel to prevent the bottom door from being spaced downward from the barrel while the lower portion of the barrel is sealed by the floor door. In this way, while the bottom door and the barrel are locked by the locking device, the thermal decomposition of the waste flowing into the barrel proceeds, and when the thermal decomposition and final incineration are completed, the locking device is first released. When the locking device is unlocked, the bottom door is lowered from the barrel by a hydraulic cylinder, and the incineration ash accumulated on the bottom door lowered from the barrel is removed by an automatic ash disposal device including a scraper.

However, the conventional locking device is equipped to be manually locked and unlocked by the operator. If the bottom door part is lowered without unlocking the locking device due to the operator's mistake, the force that lowers the bottom door part is applied to the locking device. There is a problem that there is a risk of damage to the locking device as it falls.

In addition, there is a problem that if a mistake is made, the locking device may be damaged and the floor door may drop suddenly, causing damage to the floor door and causing a safety accident.

Hereinafter, specific embodiments for implementing the spirit of the present invention will be described in detail with reference to the drawings. In describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

Hereinafter, a pyrolysis gasifier according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a pyrolysis gasifier according to an embodiment of the present invention, FIG. 2 is a plan view showing the lower part of the pyrolysis gasifier of FIG. 1, and FIG. 3 is an enlarged view of the lower part of the pyrolysis gasifier of FIG. 1. This is a drawing shown, and FIG. 4 is a view of the lower part of the pyrolysis gasification furnace of FIG. 1 from a different side than that of FIG. 3.

1 to 4, the pyrolysis gasifier 1 according to an embodiment of the present invention includes a barrel 10, a bottom door 20, a main frame 30, a base frame 40, and a ash processing unit. It may include (50).

The barrel 10 is a part where pyrolysis of waste takes place, and is provided with a waste combustion chamber 100 having a pyrolysis space where waste is pyrolyzed, a lid 110 that opens and closes the upper surface of the waste combustion chamber 100, and a lower part of the barrel 10. It may include an ignition unit 120 for igniting waste and a lower flange 130 attached to the lower surface of the waste combustion chamber 100.

The waste combustion chamber 100 may have a cylindrical shape with its upper and lower surfaces open. The upper part of the pyrolysis space of the waste combustion chamber 100 can be opened and closed by the lid 110, and the lower part can be opened and closed by the bottom door 20. Additionally, while the waste combustion chamber 100 is closed by the lid 110 and the bottom door 20, the waste combustion chamber 100 can remain sealed against the outside. Accordingly, while the waste is thermally decomposed, combustion flames, gases, etc. within the waste combustion chamber 100 may not be discharged to the outside.

The waste combustion chamber 100 may be constructed by stacking a side fire wall, a side cooling jacket, and an outer wall in the order from the inside to the outside. The side cooling jacket may be configured to receive refrigerant from the outside and allow the refrigerant to flow inside. As the refrigerant flowing inside the side cooling jacket exchanges heat with the pyrolysis space, the temperature of the refrigerant may increase. The heat energy accumulated in the refrigerant can be discharged to the outside and recycled.

A side fire wall may be disposed between the side cooling jacket and the pyrolysis space. The side firewall is made of a material with insulating properties, which may partially hinder heat exchange between the side cooling jacket and the pyrolysis space. Due to this side fire wall, the refrigerant inside the side cooling jacket may not be raised to an excessively high temperature, or the temperature inside the pyrolysis space may not be excessively lowered. The thickness of the side fire wall can be determined within the range of about 50 mm to about 100 mm, and as the thickness of the side fire wall is determined within this thickness range, there is no risk of losing its function as a fire resistant material, and there is no problem of the thermal decomposition temperature rising too much. It can be resolved.

The lid 110 has a fireproof wall 112 formed toward the inside of the waste combustion chamber 100, which can prevent the heat inside the waste combustion chamber 100 from being released upward when the lid 110 is closed. In addition, the lid 110 can be configured to be easily opened and closed by having one end pivotable with respect to the waste combustion chamber 100. For this purpose, one end of the lid 110 is provided with a hinge 116 that connects the lid 110 to the waste combustion chamber 100 so as to be rotatable, and when the lid 110 is closed, the waste combustion chamber 100 A sealing member 114 may be provided on the lower surface of the lid 110 in contact with the upper part of the 100 and in contact with the waste combustion chamber 100. This sealing member 114 can prevent gas inside the waste combustion chamber 100 from being discharged to the outside.

The main frame 30, the base frame 40, and the guide frame 500 of the ash processing unit 50, which will be described later, may each be configured as a hexahedral frame-shaped structure in which a plurality of I-beams are bonded and connected to each other. In addition, a first hoist 310 and a second hoist 320 may be installed on the upper part of the main frame 30, and a basket traveling rail 340 extending in the vertical direction may be installed on the side.

Meanwhile, the driving of the first hoist 310 and the second hoist 320 may be controlled by the control unit 90 (see FIG. 16). For example, in the contact detection unit 80 (see FIG. 16), the locking unit 620 of the automatic locking device 60 (see FIG. 16), which will be described later, is received and contacted in the receiving groove 631 of the restraint unit 630. When detected, the control unit 90 determines that the cylinder 10 and the floor door 20 are locked, and controls the operation of the first hoist 310 and the second hoist 320, so that the cylinder 10 Waste is put in, and the upper part of the barrel 10 can be closed with the lid 110.

Examples of waste that is input into the waste combustion chamber 100 and pyrolyzed include SRF molded fuel, SRF non- molded solid fuel, bio SRF solid fuel, waste tires, and TDF made by turning waste tires into chips. , and other combustible mixed wastes produced for recycling by mechanically crushing, pulverizing, and sorting household or industrial wastes.

The ignition unit 120 is formed in the lower part of the cylinder 10 and can ignite the combustible waste inside the waste combustion chamber 100 to generate a flame and initiate thermal decomposition. The ignition unit 120 may be installed at a plurality of positions along the circumference of the waste combustion chamber 100, and for example, may be arranged at four positions at regular intervals.

The ignition unit 120 operates by sliding an ignition tube that provides a passage through which a flame is introduced into the waste combustion chamber 100, a spark plug that generates a flame into the inside of the ignition tube, a damper provided at the end of the ignition tube, and a damper. It may include a cylinder that opens and closes the end of the ignition tube. The cylinder may be comprised of a pneumatic cylinder, hydraulic cylinder, or screw jack.

Accordingly, when a spark is generated from the spark plug, the flame is transmitted to the inside of the waste combustion chamber 100 through the ignition pipe and ignition occurs. After ignition is carried out for a predetermined time, when combustion begins in the combustible waste, the damper slides. This closes the end of the ignition tube. As a result, the flame can be transmitted only for the time required for ignition, so the waste can be ignited automatically and safely even if the worker does not manually ignite it.

Meanwhile, the ignition unit 120 may be controlled by the control unit 90 (see FIG. 16), and the control unit 90 controls the ignition unit 120 based on the detection value detected by the contact detection unit 80. can do. For example, when the contact detection unit 80 detects that the locking unit 620 of the automatic locking device 60 (see FIG. 16), which will be described later, is accommodated in the restraint unit 630, the control unit 90 detects the ignition unit 120 ) is driven to ignite the combustible waste inside the waste combustion chamber 100 to generate a flame and allow thermal decomposition to begin.

The lower flange 130 is a member attached to the lower surface of the waste combustion chamber 100 and may be provided in a square shape. The interior of the lower flange 130 may be configured to have a communication hole communicating with the pyrolysis space. Additionally, the lower flange 130 may include a packing member 25 that seals the gap between the waste combustion chamber 100 and the bottom door 20 when pressed by the sealing ring of the bottom door 20. The packing member 25 may be provided opposite the bottom door portion 20. For example, the packing member 25 may be made of an elastic material to form a sealed environment, and may be provided in the shape of a square ring according to the shape of the lower flange 130.

The bottom door 20 may be disposed on the lower side of the cylinder 10 to selectively seal the lower portion of the cylinder 10.

For this purpose, the bottom door part 20 includes a door body 200 selectively in close contact with the lower part of the barrel 10, a lower fireproof wall 202 provided on the upper surface of the door body 200, and a pyrolysis space necessary for combustion.

An elevating means 250 and a base It may include a guide post 260 that is installed to be movable up and down on the frame 40 and whose upper end is connected to the door body 200.

The door body 200 may be stacked from the top to the lower fire wall 202, lower cooling jacket 240, and air pocket 220. The lower fire wall 202 may be made of the same material as the side fire wall, and a plurality of nozzle receiving grooves in which the end of the air supply nozzle 210 is accommodated may be formed on the upper surface. As the end of the air supply nozzle 210 is accommodated in the nozzle receiving groove, the air supply nozzle 210 does not protrude above the upper surface of the lower fire wall 202, so the air supply nozzle 210 is injected into the waste and The risk of collision and damage can be prevented. Additionally, the position of the lower fire wall 202 within the floor door portion 20 can be fixed by a circular frame provided on the edge portion.

The air supply nozzle 210 is formed to protrude into the nozzle receiving groove of the lower fire wall 202, and may be provided in plural numbers. At least a portion of the air supply duct 230 is composed of a bellows pipe 232 and may be provided to extend or contract accordingly when the floor door portion 20 is raised or lowered. In addition, it may further include a blowing fan 234 that is connected to the end of the air supply duct 230 and supplies external air to the air pocket 220.

Like the side cooling jacket, the lower cooling jacket 240 may be configured to receive refrigerant from the outside and allow the refrigerant to flow inside. As the refrigerant flowing inside the lower cooling jacket 240 exchanges heat with the pyrolysis space, the temperature of the refrigerant inside the lower cooling jacket 240 may increase. The heat energy accumulated in the refrigerant can be discharged to the outside and recycled. In addition, heat exchange between the lower cooling jacket 240 and the pyrolysis space is partially interrupted by the lower fire wall 202, so that the refrigerant inside the lower cooling jacket 240 rises to an excessively high temperature or the temperature inside the pyrolysis space increases. It may not be excessively low. The thickness of the lower fire wall 202, like the side fire wall, may be determined within the range of about 50 mm to about 100 mm.

The lower cooling jacket 240 may be connected to a refrigerant supply pipe 242, which provides a passage through which refrigerant is supplied from an external refrigerant source, and a refrigerant discharge pipe 244, which provides a passage through which refrigerant is discharged to the outside. In addition, the refrigerant supply pipe 242 and the refrigerant discharge pipe 244 are connected to a high-pressure hose or flexible hose along the way, and the high-pressure hose or flexible hose is a cable bear 246 whose shape can be changed in response to the raising and lowering of the door body 200. ) can be provided to be supported by. Accordingly, the refrigerant supply pipe 242 and the refrigerant discharge pipe 244 can be prevented from being damaged due to the raising or lowering of the door body 200.

The lifting means 250 is connected to the lower part of the door body 200 and moves the door body 200 to a preset first position (H1, see Figure 15) or a second position (H2, Figure 15) different from the first position (H1).

At this time, the first insertion point (BDC) refers to the position of the piston 254 when the end of the piston 254 is furthest from the cylinder 252, and the second insertion point (TDC) refers to the position of the piston 254. This means the position of the piston 254 when the end of (254) is closest to the cylinder 252.

When the end of the piston 254 is furthest from the cylinder 252, the position sensing unit 70 (see FIG. 15) detects the piston 254 at both the first insertion point (BDC) and the second insertion point (TDC). cannot be detected. In contrast, if the end of the piston 254 is closest to the cylinder 252, the position detection unit 70 can detect the piston 254 at both the first insertion point (BDC) and the second insertion point (TDC). You can.

When the piston 254 is detected at both the first insertion point (BDC) and the second insertion point (TDC) through the position detection unit 70, the position detection unit 70 may generate a detection ON signal.

The guide frame 500 includes a driving guide 502 and an automatic reprocessor 510 that accommodate at least a portion of the driven wheels 517 and 518 of the automatic reprocessor 510 and guide the movement of the driven wheels 517 and 518. It may include a stopper 504 that prevents the guide frame 500 from deviating to the outside.

The traveling guide 502 may be provided as a side portion of an I-beam extending in one direction constituting a part of the guide frame 500. Specifically, the cross section constituting the side portion of the I-beam has a “ㄷ” shape. It can be defined as space. As the driven wheels 517 and 518 are accommodated and driven in this “ㄷ” shaped space, the travel of the automatic reprocessor 510 can be guided by the travel guide 502.

The stopper 504 is a driven wheel ( 517, 518) and may be placed in contact with the travel direction on the opposite side, and may be provided to partially close the “ㄷ” shaped space of the travel guide 502. However, this is only an example, and a stopper 504 may be provided on the rack gear frame 520 to prevent the automatic reprocessor 510 from leaving.

The automatic reprocessor 510 includes a driving gear 516 configured to engage with the rack gear 522, a driving member 512 connected to the driving gear 516 to provide rotational force to the driving gear 516, and a driving member ( A drive belt 514 that connects 512 and the drive gear 516 to transmit the power generated by the drive member 512 to the drive gear 516, and a first driven wheel 517 coaxially connected to the drive gear 516. ), a second driven wheel 518 having a different axis from the first driven wheel 517, and a push plate 519 provided at the front of the automatic reprocessor 510 to push out the ashes (X). there is. In this embodiment, the case where the drive member 512 and the drive gear 516 are connected through a drive belt has been described as an example, but this is only an example and does not limit the spirit of the present invention. The driving member 512 and the driving gear 516 may be connected through a driving chain or the like.

When the operation of the driving member 512 begins, the automatic reprocessor 510 begins linear movement as the driving gear 516 rotates and moves forward along the rack gear 522. At this time, the automatic reprocessor 510 is moved by the driving guide 502. The driving path can be set by guiding the driven wheels 517 and 518. When the automatic ash processor 510 travels along the guide frame 500, the ash (X) accumulated on the upper side of the floor door 20 is pushed by the push plate 519 and removed from the floor door 20. It can be. The material (X) pushed out by the push plate 519 may be loaded and discharged on the transfer conveyor 530 installed on the ground.

The rack gear frame 520 extends along the traveling direction of the automatic reprocessor 510 and may be installed on the base frame 40. A rack gear 522 is formed on the upper surface of the rack gear frame 520, and the drive gear 516 engaged with the rack gear 522 is rotated, so that the automatic reprocessor 510 runs along the rack gear 522 to process the reprocessor. (X) can be removed.

In this embodiment, the case where the rack gear frame 520 is fixedly installed on the base frame 40 is shown as an example, but this is only an example, and the rack gear frame 520 includes the main frame 30 in addition to the base frame 40. ) or can be installed on the guide frame 500.

In the process of the automatic ash processor 510 pushing the ash (X), a significant level of lateral load is applied to the lifting means 250 due to the load of the accumulated ash (X) and the cranking phenomenon generated during the combustion process. It can be. If this load fully acts on the lifting means 250, there is a risk that the lifting means 250 may be damaged.

For this reason, the guide post 260 can be provided, and the lateral load is distributed by the guide post 260, thereby significantly reducing the lateral load acting on the lifting means 250.

In addition, due to the load of the accumulated ashes ( In order to offset this, the driving force is provided to the driving gear 516 to rotate along the rack gear 522 to drive, so that an appropriate level of driving force can be secured compared to simply providing driving force to the wheel. Accordingly, the material (X) can be processed smoothly despite the cranking phenomenon that occurs during the load and combustion process of the material (X).

Meanwhile, the operation of the automatic reprocessor 510 may be controlled by the control unit 90 (see FIG. 15). To this end, the position detection unit 70 (see FIG. 15) detects whether the position of the piston 254 inserted into the cylinder 252 is located at the first insertion point (BDC) and the second insertion point (TDC). , the sensed value is transmitted to the control unit 90. The control unit 90 controls the operation of the automatic reprocessor 510 based on the detection value of the position detection unit 70. For example, when the position detection unit 70 detects the piston 254 at both the first insertion point (BDC) and the second insertion point (TDC), the control unit 90 determines whether the door body 200 is completely lowered. It is determined that this is the case, and the automatic ash processor 510 is driven to allow the incineration ash treatment process to proceed.

Below, the automatic locking device 60 will be described with reference to FIGS. 12 to 14. FIG. 12 is a plan view illustrating the arrangement of the automatic locking device of the pyrolysis gasifier of FIG. 1, FIG. 13 is a view showing the automatic locking device of the pyrolysis gasifier of FIG. 1, and FIG. 14 is a view of the automatic locking device of FIG. 13. This is a diagram explaining the locking operation.

12 to 14, the automatic locking device 60 can selectively lock the barrel portion 10 and the bottom door portion 20. For example, the automatic locking device 60 prevents the bottom door 20 from being spaced downward from the barrel 10 while the bottom door 20 seals the lower part of the barrel 10. (20) and the barrel portion (10) can be locked.

For this purpose, the automatic locking device 60 is provided on the circumferential surface of the barrel 10 and the bottom door 20, for example, a total of 8 along the circumference of the barrel 10 and the bottom door 20. Can be arranged in various locations. However, this is only an example, and the number of automatic locking devices 60 can be set arbitrarily.

The automatic locking device 60 may include a power generation unit 600, a power relay unit 610, a locking unit 620, and a restraining unit 630.

The power generator 600 is a component that generates and provides power for the automatic locking device 60 to operate, and may be provided as a device that receives power from the outside and converts it into mechanical power. For example, the power generator 600 may be provided as a hydraulic cylinder, pneumatic cylinder, motor, etc. The power generation unit 600 may be installed in the cylinder 10 and connected to the power relay unit 610 to enable power transmission.

For example, the power generation unit 600 may be provided with a cylinder 601 and a piston 602 provided to the cylinder 601 in a double-acting manner. The cylinder 601 is rotatably installed through a hinge member 6011 fixed to the circumferential surface of the cylinder 10, and the piston 602 can be connected to the power relay unit 610 through a link connection member 6021. there is. Accordingly, the power generation unit 600 may be rotatably connected to the power relay unit 610. At this time, the load of the floor door part 20 acts on the locking part 620, and this can be transmitted to the hinge member 6011 through the power relay part 610. The hinge member 6011 may be rotatably connected to a support member (not shown) so that its position does not change even when a load or torque is applied. Accordingly, its position will be fixed even if a load is applied to the floor door portion 20. You can. Here, the support member may be provided, for example, as a part of a frame supporting the barrel portion 10 or the floor door portion 20 or as a separate member connected to this frame.

The power relay unit 610 is connected to the power generator 600 to transmit power and can relay the power generated by the power generator 600 to the locking unit 620. In other words, the power relay unit 610 may receive power from the power generator 600 and relay it to the locking unit 620.

The power relay unit 610 is connected to the power generator 600 and includes a cam member 611 that receives power from the power generator 600 and rotates in one direction or the other, and a cam member 611 and a locking unit. It may include a locking connection member 612 connecting 620 .

The cam member 611 may be provided to rotate in one direction when the power generation unit 600 is controlled to operate in one direction, and to rotate in the other direction when the power generation unit 600 is controlled to operate in the other direction.

At this time, the rotation axis member 6111 constituting the main axis of the cam member 611 may be connected to the link connection member 6021. The rotation axis member 6111 and the link connection member 6021 may be connected to each other through a connection key (not shown) and fixed to each other so as not to rotate relative to each other. Accordingly, the mechanical power of the power generation unit 600 can rotate the link connection member 6021 around the rotation axis member 6111, and this rotational force is directly transmitted to the cam member 611 to rotate the cam member 611. ) It can also be rotated around the rotation axis member 6111. Although not shown, the rotation axis member 6111 may be rotatably supported by, for example, a bearing.

Meanwhile, the cam member 611 may be divided into a first perimeter formed at a first length, a second perimeter formed at a second length different from the first length, and a third perimeter connecting the first perimeter and the second perimeter. At this time, at least a portion of the third circumference may be provided with a guiding groove 6112 into which the locking connection member 612 is movably inserted.

When the cam member 611 rotates while the locking connection member 612 is accommodated in the guiding groove 6112, the locking connecting member 612 may move along the path formed in the guiding groove 6112. At this time, because the first and second perimeters of the cam member 611 are formed to have different lengths, when the locking connection member 612 moves along the guiding groove 6112, it may be pushed in one direction in some sections. As a result, the locking part 620 can be accommodated in the receiving groove 631 of the restraining part 630.

The locking part 620 may be moved by the power generated by the power generating part 600 and come into contact with the restraining part 630. Specifically, the locking part 620 moved by the power generated from the power generating part 600 can be selectively accommodated in the receiving groove 631 provided in the restraining part 630.

When the locking part 620 is accommodated in the receiving groove 631, the movement of the locking part 620 is restricted by the restraining part 630, so the barrel part 10 and the bottom door part 20 are locked and relative to each other. The position is fixed so that it does not change, and when the locking part 620 accommodated in the receiving groove 631 is separated from the receiving groove 631, the barrel part 10 and the bottom door part 20 are unlocked and the mutual positions are variable. It can be.

The locking unit 620 is connected to the locking connection member 612 and is provided to perform a double-acting movement in a preset path by the movement of the locking connection member 612. The double-acting movement path of the locking unit 620 may be set by a locking guide unit (not shown). As the locking part 620 moves along the locking guide, it may selectively contact the restraint part 630.

The restraining unit 630 may contact at least a portion of the locking unit 620 moved by the power generated by the power generating unit 600 to restrict the position of the locking unit 620. If the position of the locking part 620 is restricted by the restraining part 630, the downward movement of the bottom door part 20 in close contact with the lower side of the cylinder part 10 may also be restricted.

To this end, the restraining part 630 may be provided with a receiving groove 631 in which at least a portion of the locking part 620 can be accommodated. Interference between the locking part 620 and the restraining part 630 can prevent the bottom door part 20 from descending due to gravity, and as a result, the barrel part 10 and the bottom door part 20 are locked to each other and face each other. Movement may be restricted.

The locking connection member 612 moves by rotation of the cam member 611, and the double-acting movement of the locking portion 620 can be implemented by the movement of the locking connection member 612. For example, when the cam member 611 rotates in one direction, the locking portion 620 is received by the restraint portion 630 and is in a locked state, and when the cam member 611 rotates in the other direction, the locking portion 620 The locking state may be released by moving away from the restraint part 630.

In this way, the operation of the power generation unit 600 can be controlled, and when the power generation unit 600 is controlled to operate in one direction, the cam member 611 rotates in one direction, and thus the locking unit 620 may move in one direction and be inserted into the restraint part 630 and be in a locked state (FIG. 13). Conversely, when the power generation unit 600 is controlled to operate in the other direction, the cam member 611 rotates in the other direction, and accordingly, the locking unit 620 moves in the other direction and locks when moving away from the restraint unit 630. The state can be released (Figure 14).

Hereinafter, the position detection unit 70, the contact detection unit 80, and the control unit 90 will be described with reference to FIGS. 15 and 16. FIG. 15 is a diagram explaining the control operation of the control unit according to the position detection unit of the pyrolysis gasification furnace of FIG. 1, and FIG. 16 is a diagram explaining the control operation of the control unit according to the contact detection unit of the pyrolysis gasification furnace of FIG. 1.

Referring to FIG. 15 , the position detection unit 70 can detect the position of the door body 200 raised or lowered by the lifting means 250. The position detection unit 70 can determine the position of the door body 200 by detecting the position of the piston 254 with respect to the cylinder 252 of the lifting means 250. For example, the position detection unit 70 may be provided with a sensor such as a limit switch.

When the piston 254 is detected at both the first insertion point (BDC, bottom dead center) and the second insertion point (TDC, top dead center) through the position detection unit 70, the position detection unit 70 sends a detection ON signal. can be created. In addition, if the piston 254 is not detected at both the first insertion point (BDC) and the second insertion point (TDC) through the position detection unit 70, the position detection unit 70 may generate a detection OFF signal. You can. The detection ON signal and detection OFF signal generated in this way can be transmitted to the control unit 90 and used to control the automatic locking device 60 and the reprocessing unit 50.

For example, when the piston 254 reaches the bottom dead center, a detection OFF signal is transmitted from the position detection unit 70 to the control unit 90, and the control unit 90 determines that the piston 254 is located at the bottom dead center. After determining that the operation of the lifting means 250 is stopped, the operation of the automatic locking device 60 is controlled so that the locking of the barrel portion 10 and the floor door portion 20 begins.

When the locking operation of the automatic locking device 60 starts through the control unit 90, power is generated in the power generator 600, and the locking unit 620 moves forward by the power generated by the power generator 600. Thus, it can be accommodated in the receiving groove 631 of the restraint part 630.

Referring to FIG. 16, the contact detection unit 80 can detect whether the locking unit 620 is in contact with the restraining unit 630. The contact detection unit 80 can determine whether the locking unit 620 is in contact with the restraining unit 630 by detecting whether the position where the locking unit 620 is in contact with the restraining unit 630 is a preset position.

When the locking unit 620 is received and contacted in the receiving groove 631 of the restraint unit 630 through the contact detection unit 80, the contact detection unit 80 generates a contact ON signal, and the contact detection unit ( When the locking unit 620 is not in contact with the receiving groove 631 of the restraining unit 630 through 80, the contact detection unit 80 may generate a contact OFF signal. The contact ON signal and contact OFF signal generated in this way can be used to control the first hoist 310, the second hoist 320, the ignition unit 120, and the lifting means 250.

When the contact ON signal generated by the contact detection unit 80 is transmitted to the control unit 90, the control unit 90 determines that the barrel unit 10 and the floor door unit 20 are locked, and the first hoist 310 And by controlling the driving of the second hoist 320, waste is introduced into the cylinder 10 and the upper part of the cylinder 10 is closed with the lid 110. Additionally, the operation of the ignition unit 120 is controlled to ignite the waste.

Meanwhile, at the point when thermal decomposition is completed, the control unit 90 can control the automatic locking device 60 to proceed with unlocking. In other words, when the unlocking drive of the automatic locking device 60 starts through the control unit 90, power is generated in the power generation unit 600, and the locking unit ( 620 may move backward and escape from the receiving groove 631 of the restraint portion 630.

Accordingly, when the contact OFF signal generated by the contact detection unit 80 is transmitted to the control unit 90, the control unit 90 determines that the barrel unit 10 and the floor door unit 20 are unlocked, and lifts and lowers the means ( 250) is controlled so that the bottom door part 20, which is in close contact with the lower part of the cylinder 10, is spaced apart from the cylinder 10.

When the piston 254 reaches top dead center, a detection ON signal is transmitted from the position detection unit 70 to the control unit 90, and the control unit 90 determines that the piston 254 is located at top dead center, After stopping the operation of the lifting means 250, the operation of the ash processing unit 50 is controlled so that the incineration ash treatment process can be performed.

Below, a modified example of the automatic locking device will be described with reference to FIG. 17. FIG. 17 is a diagram showing a modified example of the automatic locking device for the pyrolysis gasifier of FIG. 1.

Referring to FIG. 17, the automatic locking device 60a may include a power generating unit 600a, a power relay unit 610a, a locking unit 620a, and a restraining unit 630. Since the restraining unit 630 has been described with reference to FIG. 13, the differences between the power generating unit 600a, power relay unit 610a, and locking unit 620a will be described below.

The power generation unit 600a may be provided as a motor, for example. The power generator 600a may be placed inside the case 6101. This case 6101 may be connected to the cylinder 10 through a fastening member 6102.

The power relay unit 610a is connected to the power generator 600a, and includes a worm gear 613 that rotates by receiving power from the power generator 600a, and a pinion gear rotatably engaged with the worm gear 613 ( 614) and a rack gear 615 that moves in the front-back direction by rotation of the pinion gear 614 and is connected to the locking portion 620a.

At this time, the worm gear 613, pinion gear 614, and rack gear 615 may be disposed inside the case 6101. However, since the locking portion 620a connected to the rack gear 615 is a member accommodated in the restraining portion 630 and performs a locking operation, at least a portion of the case 6101 may be opened. The open portion of the case 6101 can be used as a passage for the locking portion 620a that moves in the front-back direction by the rack gear 615.

The worm gear 613 may be provided on the shaft 6131 connected to the power generation unit 600a. This shaft 6131 may be provided inside the case 6101. The shaft 6131 may be disposed along the front-to-back direction within the case 6101.

When the power generator 600a is controlled to rotate in one direction, the shaft 6131 rotates in one direction, and when the power generator 600a is controlled to rotate in the other direction, the shaft 6131 is rotated in the other direction. It can be.

The pinion gear 614 rotates by the worm gear 613 that rotates in conjunction with the rotation direction of the shaft 6131, and the rack gear 615 is connected to the restraint portion 630 according to the rotation direction of the pinion gear 614. It can move in a direction approaching or away from the restraint unit 630. For example, when the pinion gear 614 rotates in one direction and the rack gear 615 moves in a direction closer to the restraint portion 630, the locking portion 620a connected to the rack gear 615 also moves to the restraint portion ( It moves in a direction closer to 630 and is accommodated in the receiving groove 631 of the restraint portion 630. On the other hand, when the pinion gear 614 rotates in the other direction and the rack gear 615 moves in a direction away from the restraint portion 630, the locking portion 620a connected to the rack gear 615 also moves toward the restraint portion 630. It moves in a direction away from and is separated from the receiving groove 631 of the restraint part 630.

Below, another modified example of the automatic locking device will be described with reference to FIG. 18. FIG. 18 is a diagram showing another modification of the automatic locking device for the pyrolysis gasifier of FIG. 1.

Referring to FIG. 18, the automatic locking device 60b may include a power generating unit 600b, a power relay unit 610b, a locking unit 620b, and a restraining unit 630. Since the restraining unit 630 has been described with reference to FIG. 13, the differences between the power generating unit 600b, the power relay unit 610b, and the locking unit 620b will be described below.

The power generation unit 600b may be provided as a motor, for example. The power generator 600b may be placed inside the case 6101, and the case 6101 may be connected to the cylinder 10 through a fastening member 6102.

The power relay unit 610b is connected to the moving block 616, which selectively contacts the power generating unit 600b and moves in the forward and backward directions by receiving the power of the power generating unit 600b. An elastic body 617 that is compressed when the block 616 moves forward and generates compression restoring force, and a support block 618 that is connected to the moving block 616 through the elastic body 617 and supports the moving block 616. It can be included.

At this time, the moving block 616, the elastic body 617, and the support block 618 may be disposed inside the case 6101. However, since the locking portion 620b connected to the moving block 616 is a member accommodated in the restraining portion 630 and performs a locking operation, at least a portion of the case 6101 may be opened. The open portion of the case 6101 can be used as a passage for the locking portion 620b that moves in the front-back direction together with the movable block 616.

At this time, the locking part 620b may be connected to the surface of the peripheral surface of the moving block 616 that is opposite to the surface in contact with the power generating part 600b. When the power generation unit 600b is driven to extend, the piston side end of the power generation unit 600b presses the moving block 616, so that the moving block 616 can move in a direction closer to the restraint unit 630. . When the moving block 616 moves in a direction closer to the restraining unit 630, the locking unit 620b connected to the moving block 616 also moves in a direction closer to the restraining unit 630 and becomes closer to the restraining unit 630. It is accommodated in the receiving groove (631).

Conversely, when the power generator 600b is driven to contract, the piston-side end of the power generator 600b moves toward the cylinder-side end, so the moving block 616 can move in a direction away from the restraint portion 630. . At this time, the moving block 616 can be easily returned to its original position due to the compression restoring force of the elastic body 617. When the moving block 616 moves in a direction away from the restraining unit 630, the locking unit 620b connected to the moving block 616 also moves in a direction away from the restraining unit 630 and enters the receiving groove of the restraining unit 630. It deviates from (631).

Below, another modified example of the automatic locking device will be described with reference to FIG. 19. FIG. 19 is a diagram showing another modification of the automatic locking device for the pyrolysis gasifier of FIG. 1.

The power relay unit 610c is connected to the power generator 600c, and includes a worm gear 613 that rotates by receiving power from the power generator 600c, and a pinion gear rotatably engaged with the worm gear 613 ( 614) and a bar member 619 that is formed to have the same center of rotation as the pinion gear 614 and extends in one direction so as to rotate in conjunction with the pinion gear 614.

At this time, at least a portion of the worm gear 613, pinion gear 614, and bar member 619 may be disposed inside the case 6101. However, since the locking portion 620c connected to the bar member 619 must selectively contact the restraining portion 630a, at least a portion of the case 6101 may be opened. At least a portion of the bar member 619 may be disposed outside the case 6101 through the open portion of the case 6101.

A locking portion 620c may be connected to an end of the bar member 619 disposed outside the case 6101. The locking portion 620c connected to the end of the bar member 619 may extend in a direction that is different from the extension direction of the bar member 619. The locking portion 620c may also be rotated in conjunction with the rotation of the bar member 619.

The worm gear 613 may be provided on the shaft 6131 connected to the power generating unit 600c. This shaft 6131 may be provided inside the case 6101 and may be arranged along a vertical direction perpendicular to the front-back direction.

When the power generator 600c is controlled to rotate in one direction, the shaft 6131 rotates in one direction, and when the power generator 600c is controlled to rotate in the other direction, the shaft 6131 is rotated in the other direction. It can be.

When the locking portion 620c makes surface contact with the lower surface of the restraining portion 630a, the position of the locking portion 620c may be restricted. If the position of the locking portion 620c is restricted by the restraining portion 630a, the downward movement of the bottom door portion 20 in close contact with the lower side of the cylinder portion 10 may also be restricted.

To this end, the restraining portion 630a may be provided with a lower surface that can be in surface contact with at least a portion of the locking portion 620c. Due to the interference of the locking part 620c and the restraining part 630a, the bottom door part 20 can be prevented from descending due to gravity, and thus the barrel part 10 and the bottom door part 20 are locked to each other and face each other. Movement may be restricted.

Below, another modification of the automatic locking device will be described with reference to FIGS. 20 to 22. FIG. 20 is a view showing another modification of the automatic locking device for the pyrolysis gasification furnace of FIG. 1, FIG. 21 is a cross-sectional view taken along line B-B' of FIG. 20, and FIG. 23 is a plan view viewed from part C of FIG. 20.

The plate member 603 is a square-shaped plate, and the plate member 603 may be provided with a through hole through which the end of the piston 6002 can pass. A bar member 604 may be coupled to the front of the plate member 603. One end of the bar member 604 may be coupled to the front of the plate member 603, and the other end of the bar member 604 may be coupled to the rear of the locking guide portion 640. A bar member 604 may be provided at each corner of the plate member 603. Since the bar member 604 is provided at the corner of the plate member 603, a predetermined space can be secured between the plate member 603 and the locking guide portion 640, and the piston 6002 ) and the power relay unit 610d can be moved forward or backward.

The power relay unit 610d can transmit the power generated by the power generation unit 600d to the locking unit 620d. To this end, the power relay unit 610d may include a cylinder housing 6103 and a moving plate 6104.

The cylinder housing 6103 can move forward or backward by receiving power from the power generator 600d. To this end, the cylinder housing 6103 may be coupled to the end of the piston 6002. For example, the cylinder housing 6103 may be provided in a cylindrical shape with a hole H through which at least a portion of the end of the piston 6002 can be fixed in an inserted state.

A moving plate 6104 may be coupled to the front of the cylinder housing 6103. Since the cylinder housing 6103 and the moving plate 6104 are fixed to each other in this way, when the piston 6002 moves forward or backward with respect to the double-acting cylinder 6001, the cylinder housing 6103 and the moving plate 6104 also move. They can move forward or backward together.

Meanwhile, a locking portion 620d may be coupled to the moving plate 6104. At least a portion of the locking part 620d may be coupled to the rear of the moving plate 6104, and the remainder of the locking part 620d may protrude to the front of the moving plate 6104. The portion protruding from the front of the moving plate 6104 can be movably inserted into the locking guide portion 640. This will be explained later.

The cylinder housing 6103 and the pair of locking parts 620d may be coupled to the rear of the moving plate 6104, and the pair of locking parts 620d may be arranged left and right with the cylinder housing 6103 in between. You can.

The locking unit 620d may be moved forward or backward by power transmitted through the power relay unit 610d. When the locking part 620d moves forward, it may come into contact with the restraint part 630d, and when the locking part 620d moves backward, the contact state of the restraint part 630d may be released. For example, the locking part 620d may be provided as a sliding shaft.

The end of the locking part 620d can selectively enter between the wings 6302 of the restraining part 630d, which will be described later, and when the locking part 620d enters the space between the wings 6302, the locking part 620d is locked. Since the movement of the part 620d is restricted by the wing part 6302, the barrel part 10 and the bottom door part 20 can be locked and fixed so that their positions do not change relative to each other. On the other hand, when the locking part 620d moves out of the space between the wings 6302, the barrel part 10 and the bottom door part 20 are unlocked and their positions can be changed.

The restraint portion 630d may be divided into a coupling portion 6301 and a plurality of wing portions 6302. The coupling portion 6301 and the plurality of wing portions 6302 may be integrally formed or manufactured separately and then coupled to each other. The coupling part 6301 is a part that is coupled to the barrel part 10, and the wing part 6302 is a part that protrudes from the rear of the coupling part 6301 and refers to a part that selectively contacts the end of the locking part (620d). do. The plurality of wing parts 6302 may be spaced apart at predetermined intervals, and the space between adjacent wing parts 6302 can be used as a space into which the locking part 620d can enter.

For this purpose, the locking guide portion 640 may be disposed on the front of the moving plate 6104, and a hole 6401 into which the locking portion 620d protruding from the front of the moving plate 6104 can be movably inserted is provided. can be provided.

A bearing cover 644 may be provided between the locking guide unit 640 and the moving plate 6104. An oilless bearing 645 may be connected to the bearing cover 644, and the oilless bearing 645 is inserted into the hole 6401 formed in the locking guide part 640 to move the locking part 620d forward and backward. We can assist you in making this happen smoothly.

Hereinafter, the operation and effects of the pyrolysis gasification furnace having the above-described configuration will be described with reference to FIG. 23.

FIG. 23 is a flow chart explaining the locking operation and unlocking operation of the automatic locking device for the pyrolysis gasifier of FIG. 1.

Referring to Figure 23, first, the door body 200 is raised by driving the lifting means 250 (S10). When the door body 200 rises, the door body 200 comes into close contact with the lower side of the cylinder portion 10.

When the door body 200 is in close contact with the lower side of the cylinder 10 and the lower part of the cylinder 10 is sealed by the bottom door 20, the control unit 90 lowers the piston 254 of the lifting means 250. Determine whether it is located at the point (S20). Upon receiving the ON signal detected by the position detection unit 70, the control unit 90 determines that the piston 254 is located at the bottom dead center, and automatically locks the barrel 10 and the bottom door 20 to start locking. Control the operation of the device 60 (S30).

When the automatic locking device 60 starts operating through the control unit 90, power is generated in the power generation unit 600, and the locking unit 620 is moved by the power generated by the power generation unit 600. It may be received and contacted in the receiving groove 631 of the restraint portion 630.

Whether the locking part 620 is in contact with the restraining part 630 is detected by the contact detection unit 60. When the contact detection unit 60 detects that the locking unit 620 is received in the receiving groove 631 of the restraint unit 630, the control unit 90 recognizes that the barrel unit 10 and the bottom door unit 20 are locked. Do (S40).

When the cylinder 10 and the bottom door 20 are locked in this way, waste is input into the waste combustion chamber 100 in the cylinder 10, and the pyrolysis process of the waste proceeds (S50).

Specifically, when the waste is completely loaded into the waste input basket 330, the control unit 90 drives the second hoist 320 to open the lid 110 and then drives the first hoist 310 to load the waste. The input basket 330 rises along the basket running rail 340 to provide access to the lid 110.

Since the basket running rail 340 is bent toward the lid 110 on the lid 110 side, the waste input basket 330 rotates on the lid 110 side to discharge waste into the waste combustion chamber 100 of the barrel 10. It can be poured and loaded. When the loading of waste into the waste combustion chamber 100 is completed, the lid 110 is closed again to seal the waste combustion chamber 100. Afterwards, the ignition unit 120 is driven by the control unit 90, so that combustion of the waste can occur.

When combustion is completed, unlocking of the barrel portion 10 and the bottom door portion 20 begins (S60). For this purpose, the control unit 90 controls the automatic locking device 60. When the automatic locking device 60 starts operating through the control unit 90, power is generated in the power generation unit 600, and the locking unit 620 is moved by the power generated by the power generation unit 600. It is separated from the receiving groove 631 of the restraint portion 630.

Whether the locking part 620 is separated from the restraining part 630 is detected by the contact sensor 80. When the contact detection unit 80 detects that the locking unit 620 is not accommodated in the receiving groove 631 of the restraint unit 630, the control unit 90 unblocks the barrel unit 10 and the bottom door unit 20. It recognizes that it is locked (S70).

When the barrel 10 and the bottom door 20 are unlocked, the control unit 90 controls the lifting means 250 to move the door body 200, which is in close contact with the lower part of the barrel 10, away from the barrel 10. Do as much as possible (S80).

When the door body 200 is separated from the lower part of the cylinder 10, the control unit 90 determines whether the piston 254 of the lifting means 250 is located at top dead center (S90). Upon receiving the detection ON signal from the position detection unit 70, the control unit 90 determines that the piston 254 is located at top dead center and controls the operation of the ash processing unit 50 so that the incineration ash treatment process proceeds (S100) ).

Specifically, the automatic reprocessor 510 of the reprocessing unit 50 may start driving. To this end, when the driving member 512 starts driving, the driving force of the driving member 512 is transmitted to the driving gear 516 through the driving belt 514, so that the driving gear 516 can start rotating.

The driving gear 516 rotates and moves forward simultaneously along the rack gear 522 of the rack gear frame 520, and accordingly, the first driven wheel 517 coaxially connected to the driving gear 516 also starts rotating. It is possible to drive while being guided along the driving guide 502 of the guide frame 500.

As the automatic ash processor 510 travels, the push plate 519 pushes the ash (X) to the outside of the door body 200, causing the ash (X) to fall. Additionally, a transfer conveyor 530 is disposed at the point where the material (X) falls, so that the fallen material (X) can be discharged by the transfer conveyor (530).

When the fallen ash (X) is discharged by the transfer conveyor 530, the control unit 90 determines whether the incineration ash treatment process of the ash processing unit 50 is completed (S100). When it is determined that the incineration ash treatment process is complete, the control unit 90 raises the floor door unit 20 again and repeats the above-described steps.

According to the pyrolysis gasifier including the automatic locking device according to the present embodiment as described above, the device for locking the bottom door portion 20 and the barrel portion 10 is automated to prevent device damage and safety accidents due to operator error. This has the effect of eliminating risk.
