[0001] The technology disclosed in the present application relates to combustion equipment.

Background Art

[0002] In a combustion device provided in combustion equipment, the supplied object to be processed is incinerated. When the combustion state of the object to be processed is stable, the long life of the combustion equipment can be expected. Therefore, it is preferable to stabilize the combustion state.

[0003] However, when the supply amount of the object to be processed supplied to the combustion device fluctuates, the combustion state is also likely to fluctuate, and as a result, it may affect the service life of the combustion equipment.

[0004] Therefore, in the technology described in Patent Document 1, when the object to be burned is introduced into the incinerator using a conveyor, the height of the object to be burned on the conveyor is detected, and the combustion conditions are controlled based on the detected height.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the technology described in Patent Document 1, although a sensor or a camera is provided to detect the height of the object to be burned, the fluctuation in the supply amount of the object to be burned supplied to the incinerator cannot be reduced.

[0007] The problem of the technology disclosed in the present application is to provide a combustion equipment capable of stabilizing the combustion state of the object to be processed in the combustion device.

Means for Solving the Problems

[0008] According to the first feature, the combustion equipment comprises a combustion device for incinerating the material to be processed, a supply conveyor installed on the supply path to the combustion device for transporting the material to be processed, and an adjustment device downstream of the supply conveyor for adjusting the amount of material to be processed.

[0009] In the combustion equipment relating to the first feature, if the supply amount of material to be processed is adjusted downstream of the supply conveyor by the adjustment device, fluctuations in the supply amount of material to be processed supplied to the combustion device can be reduced even if there are variations in the material on the supply conveyor. Therefore, the combustion state of the material to be processed in the combustion device can be stabilized.

[0010] According to the second feature, in the combustion equipment relating to the first feature, the adjustment device adjusts the amount of material to be processed per unit time so as not to exceed a predetermined amount downstream of the supply conveyor.

[0011] In the combustion equipment relating to the second feature, if the adjustment device adjusts the amount of material to be processed per unit time in the downstream supply path so as not to exceed a predetermined amount, fluctuations in the amount of material supplied to the combustion device can be further reduced even if there are variations in the material to be processed on the supply conveyor. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be reliably ensured.

[0012] According to the third feature, in a combustion equipment relating to the first or second feature, the adjustment device includes a first sensor that detects the accumulation state of the material to be processed in the downstream supply path from the outlet of the supply conveyor to the inlet of the combustion equipment. Based on the accumulation state detected by the first sensor, the adjustment device adjusts the amount of material to be processed supplied per unit time in the downstream supply path so as not to exceed a predetermined amount.

[0013] In the combustion equipment relating to the third feature, the use of the first sensor makes it easier to reduce fluctuations in the downstream supply amount of the material to be processed per unit time supplied to the combustion device. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be reliably achieved.

[0014] According to the fourth feature, in the combustion equipment relating to the third feature, the adjustment device includes an adjustment control unit that controls the supply conveyor based on the accumulation state detected by the first sensor.

[0015] In the combustion equipment relating to the fourth feature, the adjustment control unit controls the opening and closing of the first damper, thereby temporarily accumulating the material to be processed discharged from the supply conveyor on the first damper, and opening and closing the first damper at a timing that reduces fluctuations in the downstream supply amount. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0016] According to the fifth feature, in the combustion equipment relating to the fourth feature, the adjustment control unit continues to operate the supply conveyor until the accumulation state detected by the first sensor reaches the first reference state. The adjustment control unit stops the operation of the supply conveyor when the accumulation state detected by the first sensor reaches the first reference state. After stopping the operation of the supply conveyor, the adjustment control unit restarts the operation of the supply conveyor if the accumulation state detected by the first sensor has not reached the first reference state.

[0017] In the combustion equipment relating to the fifth feature, when the accumulation state reaches the first reference state, the material to be processed accumulated on the first damper is discharged downstream, thereby reducing fluctuations in the downstream supply amount. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0018] According to the sixth feature, in the combustion equipment relating to the fourth or fifth feature, the adjustment device includes a first damper that opens and closes the downstream supply path. The first damper has a first closed state and a first open state. The first damper is positioned so that the material to be processed discharged from the supply conveyor accumulates on the first damper in the first closed state. By changing from the first closed state to the first open state, the material to be processed accumulated on the first damper is discharged downstream. The first sensor detects the accumulation state of the material to be processed on the first damper in the first closed state.

[0019] In the combustion equipment relating to the sixth feature, the material to be processed discharged from the supply conveyor is temporarily stored on the first damper, and the first damper can be opened and closed according to the accumulation state of the material on the first damper by using the output of the first sensor. Therefore, it becomes easier to adjust the downstream supply amount, and the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0020] According to the seventh feature, in the combustion equipment relating to the sixth feature, the first sensor detects the first distance from the first sensor to the material to be processed on the first damper as the accumulation state.

[0021] In the combustion equipment relating to the seventh feature, the accumulation state of the material to be processed on the first damper can be detected with a relatively simple configuration by detecting the first distance with the first sensor. Therefore, while suppressing an increase in the cost of the combustion equipment, the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0022] According to the eighth feature, in the combustion equipment relating to the seventh feature, the adjustment device includes an adjustment control unit that controls the supply conveyor based on the accumulation state detected by the first sensor. The adjustment control unit continues operation of the supply conveyor when the first distance is longer than the first reference distance. The adjustment control unit stops operation of the supply conveyor when the first distance is less than or equal to the first reference distance. After stopping operation of the supply conveyor, the adjustment control unit restarts operation of the supply conveyor when the first damper is in the first closed state and the first distance is longer than the first reference distance.

[0023] In the combustion equipment relating to the eighth feature, the supply conveyor is stopped when the accumulation state reaches the first reference state, thereby reducing fluctuations in the amount of material to be processed accumulated on the first damper. Consequently, fluctuations in the downstream supply amount can be reduced, and the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved while suppressing increases in the cost of the combustion equipment.

[0024] According to the ninth feature, in the combustion equipment according to any one of the sixth to eighth features, the adjustment device includes a second damper provided on the downstream side of the first damper and opening and closing the downstream supply path. The second damper has a second closed state and a second open state. The second damper is arranged such that the object to be processed discharged from the first damper accumulates on the second damper in the second closed state. The second damper discharges the object to be processed accumulated on the second damper to the downstream side when changing from the second closed state to the second open state.

[0025] According to the tenth feature, in the combustion equipment according to any one of the first to ninth features, the adjustment device includes a supply pusher. The supply pusher is provided in the downstream supply path from the outlet of the supply conveyor to the inlet of the combustion device, and supplies the object to be processed discharged from the supply conveyor to the combustion device.

[0026] In the combustion equipment according to the tenth feature, since the supply pusher can supply the object to be processed to various types of combustion devices, while enhancing the convenience of the combustion equipment, it is possible to surely stabilize the combustion state of the object to be processed in the combustion device.

Advantages of the Invention

[0027] With the technology disclosed in the present application, it is possible to provide a combustion equipment capable of stabilizing the combustion state of the object to be processed in the combustion device.

[Figure 2] Figure 2 is a partial schematic configuration diagram of the combustion equipment shown in Figure 1. [Figure 3] Figure 3 is a block diagram of the combustion equipment shown in Figure 1. [Figure 4] Figure 4 is a flowchart showing the control of the combustion equipment shown in Figure 1. [Figure 5] Figure 5 is a flowchart showing the control of the combustion equipment shown in Figure 1.

Modes for Carrying Out the Invention

[0029] The embodiments will be described below with reference to the drawings. In the drawings, the same reference numerals indicate corresponding or identical components.

[0030] As shown in Figure 1, the combustion equipment 2 comprises a receiving hopper 10, a combustion device 20, and a supply conveyor 30. The receiving hopper 10 receives the material to be processed 4. The combustion device 20 incinerates the material to be processed 4. The supply conveyor 30 is provided on the supply path from the receiving hopper 10 to the combustion device 20 and transports the material to be processed 4.

[0031] For example, the material to be processed 4 stored in the pit is fed into the receiving hopper 10 by the crane 5. The crane 5 may be operated manually by an operator, or it may be operated automatically based on the detection results of a hopper sensor installed at the top of the receiving hopper 10.

[0032] Here, the material to be processed 4 could be, for example, waste (general waste, industrial waste) and biomass. In this embodiment, the combustion equipment 2 will be described assuming the material to be processed 4 is industrial waste.

[0033] As shown in Figure 2, the supply conveyor 30 includes a conveyor casing 32 and a conveyor body 34. The conveyor casing 32 includes an inlet 32A and an outlet 32B. The conveyor body 34 transports the material to be processed 4 that enters from the inlet 32A to the outlet 32B. The conveyor body 34 includes, for example, a transport member 36 and a drive motor 38. The transport member 36 is driven by the drive motor 38 to transport the material to be processed 4. Examples of supply conveyors 30 include flight conveyors, belt conveyors, and apron conveyors. If the material to be processed 4 contains liquid, a flight conveyor is preferred as the supply conveyor 30.

[0034] The combustion equipment 2 includes a first chute 6 and a second chute 7. The first chute 6 is connected to the inlet 32A of the conveyor casing 32. The second chute 7 is connected to the outlet 32B of the conveyor casing 32.

[0035] As shown in Figure 2, the combustion equipment 2 includes an adjustment device 40. The adjustment device 40 adjusts the supply amount of material to be processed 4 on at least one of the upstream and downstream sides of the supply conveyor 30. The adjustment device 40 adjusts the supply amount of material to be processed 4 per unit time so as not to exceed a predetermined amount on at least one of the upstream and downstream sides of the supply conveyor 30. In this embodiment, the supply amount of material to be processed 4 is adjusted on both the upstream and downstream sides of the supply conveyor 30. The adjustment device 40 adjusts the supply amount of material to be processed 4 per unit time so as not to exceed a predetermined amount on both the upstream and downstream sides of the supply conveyor 30. However, the adjustment device 40 may be configured to adjust the supply amount of material to be processed 4 on only one of the upstream or downstream sides of the supply conveyor 30. The adjustment device 40 may adjust the supply amount of material to be processed 4 per unit time so as not to exceed a predetermined amount on only one of the upstream or downstream sides of the supply conveyor 30.

[0036] The adjustment device 40 adjusts the supply amount of material to be processed 4 in at least one of the upstream supply path from the outlet 10A of the receiving hopper 10 to the inlet 32A of the supply conveyor 30 and the downstream supply path from the outlet 32B of the supply conveyor 30 to the inlet 20A of the combustion device 20. The adjustment device 40 adjusts the supply amount of material to be processed 4 per unit time in both the upstream and downstream supply paths so as not to exceed a predetermined amount.

[0037] The adjustment device 40 includes a first supply pusher 50. The first supply pusher 50 is installed in the upstream supply path and supplies the material to be processed 4 from the receiving hopper 10 to the supply conveyor 30. The adjustment device 40 adjusts the upstream supply amount of the material to be processed 4 per unit time on the upstream supply path using the first supply pusher 50.

[0038] The first supply pusher 50 includes a first pusher body 52 and a first pusher drive device 54. The first pusher body 52 is provided to be movable between a forward end and a reverse end. The first pusher drive device 54 moves the first pusher body 52 between the forward end and the reverse end. The reciprocating motion of the first pusher body 52 pushes the workpiece 4 forward.

[0039] The first pusher drive device 54 includes, for example, a hydraulic cylinder 54A and a hydraulic drive circuit 54B. The hydraulic cylinder 54A is connected to the first pusher body 52. ​​The hydraulic drive circuit 54B includes a hydraulic pump and a hydraulic valve, etc. The first pusher drive device 54 may be a device other than a hydraulic device.

[0040] The first supply pusher 50 includes a first pusher casing 56. The first pusher body 52 is movably mounted within the first pusher casing 56. A hydraulic cylinder 54A is attached to the first pusher casing 56. The first pusher casing 56 is connected to the outlet 10A of the receiving hopper 10 and to the inlet 6A of the first chute 6. The first supply pusher 50 pushes the material to be processed 4 falling from the receiving hopper 10 into the first pusher casing 56 toward the first chute 6. The pushed material to be processed 4 falls into the supply conveyor 30 via the first chute 6 and is transported toward the second chute 7 by the supply conveyor 30.

[0041] The adjustment device 40 includes a first damper 70 and a second damper 80. The first damper 70 opens and closes the downstream supply path. The second damper 80 is located downstream of the first damper 70 and also opens and closes the downstream supply path. The first damper 70 and the second damper 80 constitute a double damper that separates the internal space 32S of the conveyor casing 32 of the supply conveyor 30 from the internal space 20S of the combustion device 20 (for example, the combustion chamber 26A). By providing the second damper 80 in addition to the first damper 70, the downstream supply path between the supply conveyor 30 and the combustion chamber of the combustion device 20 can always be kept closed. Therefore, it is possible to suppress or prevent air from flowing from the supply conveyor 30 to the combustion device 20, and the stabilization of the combustion state of the material to be processed in the combustion device 20 can be more reliably achieved.

[0042] The first damper 70 has a first closed state and a first open state. In the first closed state, the first damper 70 separates the upstream space from the downstream space. In the first open state, the first damper 70 connects the upstream space from the downstream space. The first damper 70 is attached to the second chute 7 and is at least partially located within the second chute 7.

[0043] The first damper 70 includes a first damper body 72 and a first damper drive device 74. The first damper body 72 is movably supported on the second chute 7. The first damper drive device 74 moves the first damper body 72 relative to the second chute 7. The first damper drive device 74 includes, for example, a hydraulic cylinder 74A and a hydraulic drive circuit 74B. The hydraulic cylinder 74A is connected to the first damper body 72. The hydraulic drive circuit 74B includes a hydraulic pump and a hydraulic valve, etc. The first damper drive device 74 may be a device other than a hydraulic device. The first damper 70 may share a hydraulic drive circuit with the first supply pusher 50.

[0044] The second damper 80 has a second closed state and a second open state. In the second closed state, the second damper 80 separates the upstream space from the downstream space. In the second open state, the second damper 80 connects the upstream space from the downstream space. The second damper 80 is attached to the second chute 7 and is at least partially located within the second chute 7.

[0045] The second damper 80 includes a second damper body 82 and a second damper drive device 84. The second damper body 82 is movably supported on the second chute 7. The second damper drive device 84 moves the second damper body 82 relative to the second chute 7. The second damper drive device 84 includes, for example, a hydraulic cylinder 84A and a hydraulic drive circuit 84B. The hydraulic cylinder 84A is connected to the second damper body 82. The hydraulic drive circuit 84B includes a hydraulic pump and a hydraulic valve, etc. The second damper drive device 84 may be a device other than a hydraulic device. The second damper 80 may share a hydraulic drive circuit with at least one of the first supply pusher 50 and the first damper 70.

[0046] The first damper 70 and the second damper 80 constitute a double damper for maintaining the sealing performance of the combustion device 20, and at the same time have the function of supplying the material to be processed 4 to the downstream side. For example, the first damper 70 is positioned so that the material to be processed 4 discharged from the supply conveyor 30 accumulates on the first damper 70 in a first closed state. The first damper 70 discharges the material to be processed 4 accumulated on the first damper 70 to the downstream side by changing from a first closed state to a first open state. The second damper 80 is positioned so that the material to be processed 4 discharged from the first damper 70 accumulates on the second damper 80 in a second closed state. The second damper 80 discharges the material to be processed 4 accumulated on the second damper 80 to the downstream side by changing from a second closed state to a second open state.

[0047] The adjustment device 40 includes a second supply pusher 90. The second supply pusher 90 is located in the downstream supply path from the outlet 32B of the supply conveyor 30 to the inlet 20A of the combustion device 20, and supplies the material to be processed 4 discharged from the supply conveyor 30 to the combustion device 20. In this embodiment, the second supply pusher 90 is located at the bottom of the second chute 7, and supplies the material to be processed 4 discharged from the second damper 80 to the combustion device 20.

[0048] The second supply pusher 90 includes a second pusher body 92 and a second pusher drive device 94. The second pusher body 92 is provided to be movable between a forward end and a reverse end. The second pusher drive device 94 moves the second pusher body 92 between the forward end and the reverse end. The reciprocating motion of the second pusher body 92 pushes the workpiece 4 forward.

[0049] The second pusher drive unit 94 includes, for example, a hydraulic cylinder 94A and a hydraulic drive circuit 94B. The hydraulic cylinder 94A is connected to the second pusher body 92. The hydraulic drive circuit 94B includes a hydraulic pump and a hydraulic valve, etc. The second pusher drive unit 94 may be a device other than a hydraulic device. The second supply pusher 90 may share a hydraulic drive circuit with at least one of the first supply pusher 50, the first damper 70, and the second damper 80.

[0050] The second supply pusher 90 includes a second pusher casing 96. The second pusher body 92 is movably mounted within the second pusher casing 96. A hydraulic cylinder 94A is attached to the second pusher casing 96. The second pusher casing 96 is connected to the outlet 7B of the second chute 7 and to the inlet 20A of the combustion device 20. The second supply pusher 90 pushes the material to be processed 4, which falls from the second damper 80 into the second pusher casing 96 via the second chute 7, toward the combustion device 20. The pushed material to be processed 4 is supplied into the combustion device 20 and incinerated.

[0051] As shown in Figure 1, the combustion apparatus 20 includes a rotary kiln 22 and an incinerator 24. The second supply pusher 90 supplies the material to be processed 4 discharged from the second damper 80 to the rotary kiln 22. The rotary kiln 22 supplies the material to be processed 4 discharged from the second supply pusher 90 to the incinerator 24. The rotary kiln 22 is rotatably mounted relative to the incinerator 24 and is inclined to descend from the second supply pusher 90 toward the incinerator 24. Therefore, the rotary kiln 22 supplies the material to be processed 4 supplied from the second supply pusher 90 to the combustion apparatus 20 while stirring it.

[0052] The incinerator 24 includes a furnace body 26 and a stoker 28. The furnace body 26 includes a combustion chamber 26A. The stoker 28 is installed inside the combustion chamber 26A. The stoker 28 burns the material to be processed by supplying air while stirring it. The combustion gas generated on the stoker 28 passes through the combustion chamber 26A, is treated by an exhaust gas treatment facility, and is discharged to the outside through a chimney. The stoker 28 includes, for example, a combustion stoker 28A and a post-combustion stoker 28B. The combustion stoker 28A and the post-combustion stoker 28B are each driven separately by a hydraulic device (not shown). In this embodiment, the combustion device 20 is a combustion device in which a rotary kiln 22 is combined with a stoker 28, but other types of combustion devices may also be used.

[0053] The rotary kiln 22 may be omitted from the combustion device 20. In that case, the material to be processed 4 is supplied to the combustion device 20 from the second supply pusher 90 either directly or via a chute. By applying the adjustment device 40 to the kiln-type combustion device, the combustion state of the material to be processed 4 in the kiln-type combustion device can be stabilized.

[0054] As shown in Figure 3, the adjustment device 40 includes an adjustment control unit 42. The adjustment control unit 42 controls the first supply pusher 50, the supply conveyor 30, the first damper 70, the second damper 80, and the second supply pusher 90. The adjustment control unit 42 is electrically connected to the first supply pusher 50, the supply conveyor 30, the first damper 70, the second damper 80, and the second supply pusher 90.

[0055] The adjustment control unit 42 includes, for example, an arithmetic unit 42P and a storage device 42M. The arithmetic unit 42P is electrically connected to the storage device 42M. The arithmetic unit 42P includes, for example, at least one of a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and a GPU (Graphic Processing Unit). When image processing is performed, it is preferable that a GPU (Graphic Processing Unit) is installed. The storage device 42M includes, for example, at least one of volatile memory and non-volatile memory. An example of volatile memory includes at least one of RAM (Random Access Memory) and DRAM (Dynamic Random Access Memory). An example of non-volatile memory includes at least one of ROM (Read Only Memory) and EEPROM (Electrically Erasable Programmable ROM).

[0056] The adjustment control unit 42 is programmed to implement the control algorithm of the combustion equipment 2. The storage device 42M of the adjustment control unit 42 stores software, such as a program for implementing the control algorithm of the combustion equipment 2. The arithmetic unit 42P implements the control algorithm of the processing unit by reading and executing the program stored in the storage device 42M. In other words, the various functions of the combustion equipment 2 are realized through the cooperation of software and hardware. For example, the adjustment control unit 42 includes a PLC (Programmable Logic Controller).

[0057] The configuration of the adjustment control unit 42 is not limited to the arithmetic unit 42P and the storage device 42M. The configuration of the arithmetic unit 42P and the storage device 42M is not limited to the configuration described above. The configuration of the adjustment control unit 42 can be realized by hardware alone or by a combination of hardware and software. Furthermore, the arithmetic unit 42P and the storage device 42M may be configured as a single chip, such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array).

[0058] As shown in Figure 2, the adjustment control unit 42 controls the first supply pusher 50 so that the amount of material to be processed 4 supplied upstream per unit time on the upstream supply path does not exceed a predetermined amount. The adjustment control unit 42 controls the first supply pusher 50 to reduce fluctuations in the amount of material to be processed 4 supplied per unit time on the upstream supply path.

[0059] The adjustment control unit 42 controls the first pusher drive unit 54 to adjust the amount of material to be processed 4 supplied from the first supply pusher 50 to the supply conveyor 30. For example, the adjustment control unit 42 controls the first pusher drive unit 54 so that when the first pusher body 52 moves from the reverse end to the forward end, it moves forward for a first driving time and stops for a first stopping time, repeating this operation. When the first pusher body 52 reaches the forward end, the adjustment control unit 42 controls the first pusher drive unit 54 so that the first pusher body 52 moves from the forward end to the reverse end. In this case, the first pusher body 52 does not stop along the way.

[0060] Compared to the case where the workpiece 4 is directly supplied from the receiving hopper 10 to the supply conveyor 30, the fluctuation in the amount of workpiece 4 supplied per unit time (upstream supply amount) from the first supply pusher 50 to the supply conveyor 30 can be reduced. This reduces the variation in the workpiece 4 on the supply conveyor 30.

[0061] The adjustment control unit 42 may also control the first pusher drive unit 54 so that the first pusher body 52 does not stop midway when moving from the reverse end to the forward end. In that case, for example, the first pusher drive unit 54 is equipped with a mechanism that can change the movement speed of the first pusher body 52, and the adjustment control unit 42 adjusts the amount of workpiece 4 supplied by changing the movement speed of the first pusher body 52 via the first pusher drive unit 54. Alternatively, both inching operation using a first drive time and a first stop time and speed change may be used. At least one of the first drive time and the first stop time may be changeable.

[0062] As shown in Figure 2, the adjustment control unit 42 controls the supply conveyor 30, the first damper 70, the second damper 80, and the second supply pusher 90 so that the amount of material to be processed 4 supplied downstream per unit time on the downstream supply path does not exceed a predetermined amount. The adjustment control unit 42 controls at least one of the supply conveyor 30, the first damper 70, the second damper 80, and the second supply pusher 90 to reduce fluctuations in the amount of material to be processed 4 supplied per unit time on the downstream supply path.

[0063] The adjustment control unit 42 controls the supply conveyor 30 so that the amount of material to be processed 4 supplied from the supply conveyor 30 to the first damper 70 per unit time does not exceed a predetermined amount. For example, when the first damper 70 is in the first closed state, the adjustment control unit 42 controls the supply conveyor 30 so that it drives the supply conveyor 30 for a second drive time and stops the supply conveyor 30 for a second stop time, and repeats this operation. The adjustment control unit 42 controls the supply conveyor 30 so that it operates for a standard operating time and stops operating the supply conveyor 30 after the standard operating time has elapsed. Furthermore, as will be described later, the adjustment control unit 42 stops operating the supply conveyor 30 according to the accumulation state of the material to be processed on the first damper 70.

[0064] Furthermore, at least one of the first drive time and the first stop time may be changeable. In addition, instead of using the inching operation with the second drive time and second stop time, the transport speed of the supply conveyor 30 may be variable, or both the inching operation and speed change may be used.

[0065] The adjustment control unit 42 controls the first damper 70 so that it repeatedly opens and closes. For example, the adjustment control unit 42 controls the first damper 70 so that it maintains the first closed state for a first closing time and the first open state for a first opening time. The adjustment control unit 42 performs the opening and closing of the first damper 70 when the operation of the supply conveyor 30 is stopped.

[0066] The adjustment control unit 42 controls the second damper 80 so that it repeatedly opens and closes. For example, the adjustment control unit 42 controls the second damper 80 so that it maintains the second closed state for a second closing time and the second open state for a second opening time. The adjustment control unit 42 performs the opening and closing of the second damper 80 after the opening and closing of the first damper 70 is completed.

[0067] The adjustment control unit 42 controls the second pusher drive unit 94 so that the second pusher body 92 moves from the reverse end to the forward end and then from the forward end back to the reverse end. After the opening and closing of the second damper 80 is complete, the adjustment control unit 42 executes one round trip operation of the second supply pusher 90.

[0068] Unlike the first supply pusher 50, the second supply pusher 90 does not perform an inching motion, however, the second supply pusher 90 may perform an inching motion. Furthermore, the movement speed of the second pusher body 92 of the second supply pusher 90 may be adjustable. Alternatively, both inching motion and speed adjustment may be utilized.

[0069] The adjustment control unit 42 controls the first damper 70, the second damper 80, and the second supply pusher 90 to operate in conjunction. For example, the adjustment control unit 42 opens and closes the second damper 80 after a first waiting time has elapsed following the completion of the opening and closing of the first damper 70. The adjustment control unit 42 causes the second pusher body 92 to make one back-and-forth motion after a second waiting time has elapsed following the completion of the opening and closing of the second damper 80. The adjustment control unit 42 opens and closes the first damper 70 after a third waiting time has elapsed following the completion of one back-and-forth motion of the second pusher body 92. As a result, the material to be processed 4 accumulated on the first damper 70 is supplied to the combustion device 20.

[0070] As shown in Figure 2, the adjustment device 40 includes a first sensor 44. The first sensor 44 detects the accumulation state of the material to be processed 4 in the downstream supply path from the outlet of the supply conveyor 30 to the inlet of the combustion device 20. Based on the accumulation state detected by the first sensor 44, the adjustment device 40 adjusts the amount of material to be processed 4 supplied downstream per unit time in the downstream supply path so as not to exceed a predetermined amount. The first sensor 44 is electrically connected to the adjustment control unit 42.

[0071] In this embodiment, the first sensor 44 includes a non-contact sensor. Examples of non-contact sensors include microwave sensors, ultrasonic sensors, and laser sensors. In this embodiment, the first sensor 44 is analog, but it may also be a digital sensor switch. By using a non-contact sensor, the first sensor 44 can be installed at a distance from the workpiece 4, increasing the flexibility of the installation location and reducing the influence of the workpiece 4's properties on the first sensor 44's detection. Therefore, the operation of the adjustment device 40 becomes more stable, and the stabilization of the combustion state of the workpiece 4 in the combustion device 20 can be more reliably achieved. However, the non-contact sensor is not limited to the above example. Furthermore, the first sensor 44 may also be a contact sensor. The first sensor 44 is attached to the conveyor casing 32, but it may also be attached to other components (for example, the second chute 7).

[0072] The adjustment control unit 42 controls the supply conveyor 30 based on the accumulation state detected by the first sensor 44. For example, the adjustment control unit 42 continues to operate the supply conveyor 30 until the accumulation state detected by the first sensor 44 reaches a first reference state. The adjustment control unit 42 stops the operation of the supply conveyor 30 when the accumulation state detected by the first sensor 44 reaches the first reference state. After stopping the operation of the supply conveyor 30, the adjustment control unit 42 restarts the operation of the supply conveyor 30 if the accumulation state detected by the first sensor 44 has not reached the first reference state.

[0073] For example, the adjustment control unit 42 continues the inching operation of the supply conveyor 30 until the accumulation state detected by the first sensor 44 reaches a first reference state. The adjustment control unit 42 stops the inching operation of the supply conveyor 30 when the accumulation state detected by the first sensor 44 reaches the first reference state. After the supply conveyor 30 has stopped operating, the adjustment control unit 42 restarts the inching operation of the supply conveyor 30 if the accumulation state detected by the first sensor 44 has not reached the first reference state.

[0074] In this embodiment, the first sensor 44 detects the first distance DS1 from the first sensor 44 to the workpiece 4 on the first damper 70 as the accumulation state. The adjustment control unit 42 continues the operation of the supply conveyor 30 when the first distance DS1 is longer than the first reference distance. The adjustment control unit 42 stops the operation of the supply conveyor 30 when the first distance DS1 is less than or equal to the first reference distance. After stopping the operation of the supply conveyor 30, the adjustment control unit 42 restarts the operation of the supply conveyor 30 when the first distance DS1 is longer than the first reference distance while the first damper 70 is in the first closed state. This makes it possible to suppress or prevent the amount of workpiece 4 on the first damper 70 from exceeding a predetermined amount.

[0075] The adjustment control unit 42 controls the first damper 70 so that it repeatedly opens and closes regardless of the accumulation state detected by the first sensor 44. The adjustment control unit 42 controls the first damper 70 so that it repeatedly opens and closes regardless of the first distance DS1 detected by the first sensor 44. This reduces fluctuations in the amount of material to be processed 4 supplied to the combustion device 20 by the first damper 70, the second damper 80, and the second supply pusher 90.

[0076] As shown in Figure 2, the adjustment device 40 includes a second sensor 46. The second sensor 46 detects the accumulation state of the material to be processed 4 on the upstream supply path. For example, the second sensor 46 detects the accumulation state of the material to be processed 4 near the outlet of the first supply pusher 50. Based on the accumulation state detected by the second sensor 46, the adjustment device 40 adjusts the upstream supply amount of the material to be processed 4 per unit time on the upstream supply path so as not to exceed a predetermined amount. The second sensor 46 is electrically connected to the adjustment control unit 42.

[0077] In this embodiment, the second sensor 46 includes a non-contact sensor. Examples of non-contact sensors include microwave sensors, ultrasonic sensors, and laser sensors. In this embodiment, an analog second sensor 46 is used, but the second sensor 46 may be a digital sensor switch. By using a non-contact sensor for the second sensor 46, it can be installed at a distance from the workpiece 4, increasing the flexibility of the installation location and reducing the influence of the workpiece 4's properties on the second sensor 46's detection. Therefore, the operation of the adjustment device 40 becomes more stable, and the stabilization of the combustion state of the workpiece 4 in the combustion device 20 can be more reliably achieved. However, the non-contact sensor is not limited to the above example. Furthermore, the second sensor 46 may be a contact sensor. The second sensor 46 is attached to the first chute 6, but it may also be attached to other components (e.g., the first pusher casing 56). The second sensor 46 may be omitted from the adjustment device 40.

[0078] The adjustment control unit 42 controls the first supply pusher 50 based on the accumulation state detected by the second sensor 46. For example, the adjustment control unit 42 continues to operate the first supply pusher 50 until the accumulation state detected by the second sensor 46 reaches the second reference state. The adjustment control unit 42 stops the operation of the first supply pusher 50 when the accumulation state detected by the second sensor 46 reaches the second reference state. After stopping the operation of the first supply pusher 50, the adjustment control unit 42 restarts the operation of the first supply pusher 50 if the accumulation state detected by the second sensor 46 has not reached the second reference state.

[0079] For example, the adjustment control unit 42 continues the inching operation of the first supply pusher 50 until the accumulation state detected by the second sensor 46 reaches the second reference state. The adjustment control unit 42 stops the inching operation of the first supply pusher 50 when the accumulation state detected by the second sensor 46 reaches the second reference state. After the operation of the first supply pusher 50 is stopped, the adjustment control unit 42 restarts the inching operation of the first supply pusher 50 if the accumulation state detected by the second sensor 46 has not reached the second reference state.

[0080] In this embodiment, the second sensor 46 detects the second distance DS2 from the second sensor 46 to the workpiece 4 near the outlet of the first supply pusher 50 as the accumulation state. The adjustment control unit 42 continues the operation of the first supply pusher 50 if the second distance DS2 is longer than the second reference distance. The adjustment control unit 42 stops the operation of the first supply pusher 50 if the second distance DS2 is less than or equal to the second reference distance. After stopping the operation of the first supply pusher 50, the adjustment control unit 42 restarts the operation of the first supply pusher 50 if the second distance DS2 is longer than the second reference distance. This makes it possible to suppress or prevent the amount of workpiece 4 supplied to the supply conveyor 30 from exceeding a predetermined amount.

[0081] The adjustment control unit 42 controls the operation and stopping of the supply conveyor 30 regardless of the accumulation state detected by the second sensor 46. The adjustment control unit 42 controls the operation and stopping of the supply conveyor 30 regardless of the second distance DS2 detected by the second sensor 46. Note that the second sensor 46 may be omitted from the combustion equipment 2.

[0082] The operation of the combustion equipment 2 will be explained with reference to Figures 4 and 5.

[0083] As shown in Figure 2, in the initial state, the material to be processed 4 is fed into the receiving hopper 10. The first pusher body 52 of the first supply pusher 50 is positioned at the rear end. The first damper 70 is in the first closed state. The second damper 80 is in the second closed state. The second pusher body 92 of the second supply pusher 90 is positioned at the rear end.

[0084] As shown in Figure 4, in step S1, the adjustment control unit 42 starts the operation of the supply conveyor 30. As described above, the supply conveyor 30 performs an inching operation. After the supply conveyor 30 starts operating, the control of the first damper 70, the second damper 80, and the second supply pusher 90 shown in Figure 4 (steps S2 to S11) and the control of the first supply pusher 50 shown in Figure 5 (steps S21 to S25) are executed in parallel.

[0085] In step S2 shown in Figure 4, the adjustment control unit 42 determines whether the first distance DS1 detected by the first sensor 44 is less than or equal to the first reference distance. That is, the adjustment control unit 42 determines whether the accumulation state of the workpiece 4 on the first damper 70 has reached the first reference state. If it is determined that the first distance DS1 is longer than the first reference distance, in step S3 the adjustment control unit 42 determines whether the reference operating time has elapsed since the start of the supply conveyor 30. If it is determined in step S3 that the reference operating time has not elapsed, the process returns to step S2. On the other hand, if it is determined in step S3 that the reference operating time has elapsed, the adjustment control unit 42 stops the operation of the supply conveyor 30 in step S4. Similarly, if it is determined in step S2 that the first distance DS1 is less than or equal to the first reference distance, the adjustment control unit 42 stops the operation of the supply conveyor 30 in step S4.

[0086] In step S5, the adjustment control unit 42 determines whether or not the supply conveyor 30 is stopped. If it is determined that the supply conveyor 30 is running, step S5 is repeated. On the other hand, if it is determined that the supply conveyor 30 is stopped, the adjustment control unit 42 performs the opening and closing operations of the first damper 70 in steps S6 and S7. At this time, the object to be processed 4 on the first damper 70 falls onto the second damper 80.

[0087] After the opening and closing of the first damper 70 is completed, in steps S8 and S9, the adjustment control unit 42 performs the opening and closing operations of the second damper 80. At this time, the material to be processed 4 on the second damper 80 is discharged to the second supply pusher 90.

[0088] After the opening and closing of the second damper 80 is completed, in steps S10 and S11, the second pusher body 92 of the second supply pusher 90 moves forward from the reverse end to the forward end and then backward from the forward end, under the control of the adjustment control unit 42. As a result, the material to be processed 4 discharged from the second damper 80 is supplied to the combustion device 20. After step S11 is executed, the process returns to step S5, and after the supply conveyor 30 stops operating, the opening and closing of the first damper 70, the opening and closing of the second damper 80, and the operation of the second supply pusher 90 to complete one round trip are performed. Note that step S5 may be executed after a predetermined time has elapsed after step S11. This predetermined time may also be changed by the user.

[0089] Furthermore, after the opening and closing of the first damper 70 in steps S6 and S7 is completed, the operation of the supply conveyor 30 is started by the adjustment control unit 42 in step S1, and steps S2 to S4 are executed. That is, after the opening and closing of the first damper 70 is completed, the operation of the supply conveyor 30 is started, and when the operation of the supply conveyor 30 is stopped, the opening and closing of the first damper 70, the opening and closing of the second damper 80, and the operation of the second supply pusher 90 one round trip are performed.

[0090] As shown in Figures 4 and 5, when the supply conveyor 30 is started in step S1, the adjustment control unit 42 determines in step S21, shown in Figure 5, whether or not the supply conveyor 30 is stopped. If it is determined that the supply conveyor 30 is stopped, step S21 is repeated. On the other hand, if it is determined that the supply conveyor 30 is running, the adjustment control unit 42 starts the operation of the first supply pusher 50 in step S22.

[0091] After the first supply pusher 50 starts operation, in step S23, the adjustment control unit 42 determines whether or not the supply conveyor 30 is stopped. If it is determined that the supply conveyor 30 is stopped, in step S25, the adjustment control unit 42 stops the operation of the second supply pusher 90. If it is determined in step S23 that the supply conveyor 30 is running, in step S22, the adjustment control unit 42 determines whether or not the second distance DS2 is less than or equal to the second reference distance. If the second distance DS2 is less than or equal to the second reference distance, it can be determined that the stacking state of the workpiece 4 has reached the second reference state, so even if the supply conveyor 30 is running, the adjustment control unit 42 stops the operation of the first supply pusher 50 and the process returns to step S21. Thus, when the supply conveyor 30 is stopped, the operation of the first supply pusher 50 is also stopped. Even when the supply conveyor 30 is running, if the accumulation of the workpieces 4 downstream of the first supply pusher 50 reaches the second standard state, the operation of the first supply pusher 50 is stopped. Therefore, the variation in the workpieces 4 on the supply conveyor 30 is reduced.

[0092] According to the first feature, the combustion equipment comprises a receiving hopper for receiving the material to be processed, a combustion device for incinerating the material to be processed, a supply conveyor provided on the supply path from the receiving hopper to the combustion device for transporting the material to be processed, and an adjustment device for adjusting the amount of material to be processed on at least one of the upstream and downstream sides of the supply conveyor.

[0093] In the combustion equipment relating to the first feature, if the supply amount of material to be processed is adjusted upstream of the supply conveyor by the adjustment device, variations in the material on the supply conveyor are reduced, and fluctuations in the supply amount of material to be processed supplied to the combustion device can be reduced. Furthermore, if the supply amount of material to be processed is adjusted downstream of the supply conveyor by the adjustment device, even if there are variations in the material on the supply conveyor, fluctuations in the supply amount of material to be processed supplied to the combustion device can be reduced. Therefore, the combustion state of the material to be processed in the combustion device can be stabilized.

[0094] According to the second feature, in the combustion equipment relating to the first feature, the adjustment device adjusts the amount of material to be processed per unit time so as not to exceed a predetermined amount on at least one side of the supply conveyor, both upstream and downstream.

[0095] In the combustion equipment relating to the second feature, if the adjustment device adjusts the supply rate of the material to be processed per unit time in the upstream supply path from the outlet of the receiving hopper to the inlet of the supply conveyor so as not to exceed a predetermined amount, the variation in the material to be processed on the supply conveyor is further reduced, and as a result, fluctuations in the supply rate of the material to be processed supplied to the combustion device can be further reduced. Furthermore, if the adjustment device adjusts the supply rate of the material to be processed per unit time in the downstream supply path so as not to exceed a predetermined amount, even if there is variation in the material to be processed on the supply conveyor, fluctuations in the supply rate of the material to be processed supplied to the combustion device can be further reduced. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be reliably ensured.

[0096] According to the third feature, in a combustion equipment relating to the first or second feature, the adjustment device includes a first sensor that detects the accumulation state of the material to be processed in the downstream supply path from the outlet of the supply conveyor to the inlet of the combustion equipment. Based on the accumulation state detected by the first sensor, the adjustment device adjusts the amount of material to be processed supplied per unit time in the downstream supply path so as not to exceed a predetermined amount.

[0097] In the combustion equipment relating to the third feature, the use of the first sensor makes it easier to reduce fluctuations in the downstream supply amount of the material to be processed per unit time supplied to the combustion device. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be reliably achieved.

[0098] According to the fourth feature, in the combustion equipment relating to the third feature, the adjustment device includes an adjustment control unit that controls the supply conveyor based on the accumulation state detected by the first sensor.

[0099] In the combustion equipment relating to the fourth feature, the adjustment control unit controls the opening and closing of the first damper, thereby temporarily accumulating the material to be processed discharged from the supply conveyor on the first damper, and opening and closing the first damper at a timing that reduces fluctuations in the downstream supply amount. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0100] According to the fifth feature, in the combustion equipment relating to the fourth feature, the adjustment control unit continues to operate the supply conveyor until the accumulation state detected by the first sensor reaches the first reference state. The adjustment control unit stops the operation of the supply conveyor when the accumulation state detected by the first sensor reaches the first reference state. After stopping the operation of the supply conveyor, the adjustment control unit restarts the operation of the supply conveyor if the accumulation state detected by the first sensor has not reached the first reference state.

[0101] In the combustion equipment relating to the fifth feature, when the accumulation state reaches the first reference state, the material to be processed accumulated on the first damper is discharged downstream, thereby reducing fluctuations in the downstream supply amount. Therefore, the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0102] According to the sixth feature, in the combustion equipment relating to the fourth or fifth feature, the adjustment device includes a first damper that opens and closes the downstream supply path. The first damper has a first closed state and a first open state. The first damper is positioned so that the material to be processed discharged from the supply conveyor accumulates on the first damper in the first closed state. By changing from the first closed state to the first open state, the material to be processed accumulated on the first damper is discharged downstream. The first sensor detects the accumulation state of the material to be processed on the first damper in the first closed state.

[0103] In the combustion equipment relating to the sixth feature, the material to be processed discharged from the supply conveyor is temporarily stored on the first damper, and the first damper can be opened and closed according to the accumulation state of the material on the first damper by using the output of the first sensor. Therefore, it becomes easier to adjust the downstream supply amount, and the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0104] According to the seventh feature, in the combustion equipment relating to the sixth feature, the first sensor detects the first distance from the first sensor to the material to be processed on the first damper as the accumulation state.

[0105] In the combustion equipment relating to the seventh feature, the accumulation state of the material to be processed on the first damper can be detected with a relatively simple configuration by detecting the first distance with the first sensor. Therefore, while suppressing an increase in the cost of the combustion equipment, the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0106] According to the eighth feature, in the combustion equipment relating to the seventh feature, the adjustment control unit continues the operation of the supply conveyor when the first distance is longer than the first reference distance. The adjustment control unit stops the operation of the supply conveyor when the first distance is less than or equal to the first reference distance. After stopping the operation of the supply conveyor, the adjustment control unit restarts the operation of the supply conveyor when the first damper is in the first closed state and the first distance is longer than the first reference distance.

[0107] In the combustion equipment relating to the eighth feature, the supply conveyor is stopped when the accumulation state reaches the first reference state, thereby reducing fluctuations in the amount of material to be processed accumulated on the first damper. Consequently, fluctuations in the downstream supply amount can be reduced, and the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved while suppressing increases in the cost of the combustion equipment.

[0108] According to the ninth feature, in a combustion facility relating to any one of the first to eighth features, the adjustment device includes a first supply pusher provided in the upstream supply path from the outlet of the receiving hopper to the inlet of the supply conveyor and supplying the material to be processed from the receiving hopper to the supply conveyor, and an adjustment control unit that controls the first supply pusher so that the amount of material to be processed per unit time on the upstream supply path does not exceed a predetermined amount.

[0109] In the combustion equipment relating to the ninth feature, the first supply pusher can reduce fluctuations in the upstream supply amount, thereby reducing variations in the material to be processed on the supply conveyor. Consequently, fluctuations in the downstream supply amount are also easier to reduce, further stabilizing the combustion state of the material to be processed in the combustion device.

[0110] According to the tenth feature, in the combustion equipment according to the ninth feature, the first supply pusher includes a first pusher body that is movable between a forward end and a reverse end, and a first pusher drive device that moves the first pusher body between the forward end and the reverse end. The adjustment control unit controls the first pusher drive device to adjust the amount of material to be processed supplied from the first supply pusher to the supply conveyor.

[0111] In the combustion equipment relating to the tenth feature, the fluctuations in the upstream supply amount can be further reduced by the first pusher body, the first pusher drive device, and the adjustment control unit, and the variability of the workpiece on the supply conveyor can be further reduced. Consequently, fluctuations in the supply amount of workpiece discharged from the supply conveyor can be further reduced, and the stabilization of the combustion state of the workpiece in the combustion device can be more reliably achieved.

[0112] According to the 11th feature, in the combustion equipment relating to the 10th feature, the adjustment control unit controls the first pusher drive device so that when the first pusher body moves from the reverse end to the forward end, it repeatedly moves forward for a first driving time and stops for a first stopping time.

[0113] In the combustion equipment relating to the 11th feature, fluctuations in the upstream supply amount of the material to be processed can be reduced more reliably, and variations in the material to be processed on the supply conveyor can be reduced more reliably. Consequently, fluctuations in the supply amount of the material to be processed discharged from the supply conveyor can also be reduced more reliably, and the stabilization of the combustion state of the material to be processed in the combustion device can be more reliably achieved.

[0114] According to the twelfth feature, in a combustion facility relating to any one of the first to eleventh features, the adjustment device includes a second supply pusher. The second supply pusher is provided in the downstream supply path and supplies the material to be processed discharged from the supply conveyor to the combustion device.

[0115] In the combustion equipment relating to the 12th feature, the material to be processed can be supplied to various types of combustion devices by the second supply pusher, thereby improving the convenience of the combustion equipment while ensuring the stabilization of the combustion state of the material to be processed in the combustion device.

[0116] In this application, “equipped with” and its derivatives are non-restrictive terms that describe the existence of a component and do not exclude the existence of other components not described. This also applies to “having,” “including,” and their derivatives.

[0117] In this application, ordinal numbers such as "first" and "second" are merely terms used to identify the components and do not have any other meaning (e.g., a specific order). For example, the existence of a "first element" does not implicitly mean that a "second element" exists, nor does the existence of a "second element" implicitly mean that a "first element" exists.

[0118] Furthermore, the expression "at least one of A and B" in this disclosure includes, for example, (1) A only, (2) B only, and (3) both A and B. In this disclosure, the expression "at least one of A and B" is not construed as "at least one of A and at least one of B".

[0119] Based on the above disclosure, it is clear that various changes and modifications to the present invention are possible. Therefore, the present invention may be implemented in a manner different from the specific disclosures of this application, without departing from the spirit of the invention.
