Abstract

PROBLEM TO BE SOLVED: To permit the detection of spread of live charcoal in waste layer in nearly period as well as the facilitation of prevention of fire much more by a method wherein the bucket of a crane facility is provided with a contact type detecting means of temperature in the waste layer. SOLUTION: A protecting cylindrical body 5a is projected downwardly from a main body 3a to surround the sheath of a sheath type thermocouple 5A upon the descending of a waste bucket 3 to protect the sheath from a transversally effecting force of waste against the sheath, which is accompanied by the swinging of the bucket 3. Subsequently, when the bucket 3 is lowered and the protecting cylinder 5a is contacted with the surface of the waste layer, the protecting cylinder 5a is pushed up relatively against the downwardly extruding force of an energizing means 5b by the resistance of the surface of waste layer. In this case, the sheath type thermocouple 5A is exposed and is forced into the waste layer. Then, a control mechanism of waste layer temperature receives a signal from the thermocouple 5A and compares the same with the predetermined value of the temperature in the waste layer. When a temperature, exceeding the predetermined value, is detected, a water injecting gun is operated to inject water against a division wherein the temperature, exceeding the predetermined value, has been detected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage incineration facility, and more particularly to a garbage pit for collecting collected garbage, a crane facility for transporting garbage collected in the garbage pit, and The present invention relates to a garbage collection facility for a refuse incineration furnace having a transfer control mechanism for controlling transfer of a crane facility.

[0002]

2. Description of the Related Art Conventionally, in an integrated facility of a refuse incineration furnace, a fire may occur in a garbage layer accumulated in a garbage pit. Not equipped. In other words, there is no means for fire prevention.

[0003]

In the above-mentioned conventional garbage incinerator integrated equipment, the operation of exchanging garbage between the sections in the garbage pit is performed in order to equalize the garbage quality. Crane equipment operators responded by finding smoke or flame. Therefore, it is difficult to find a fire type in the garbage layer. In particular, if a place where smoke or a flame is generated enters a blind spot, it cannot be detected until a large amount of smoke is generated.
On the other hand, fires must be extinguished in the initial stage.If smoke can be seen from the surface of the garbage layer in the garbage pit, the fire has already ignited inside the garbage layer and the burning area has expanded, so a large amount of fire has to be extinguished. In addition to this, there is a problem that not only can the fire be extinguished easily, but also that the water in the garbage pit after extinguishing be discharged. By the way, in general firefighting activities,
It is said that firefighting must be started within 30 minutes after the fire starts, that is, before the firepower becomes strong, and if firefighting is delayed, it will be necessary to focus on fire prevention. In the above-mentioned conventional garbage incineration equipment,
Smoke can only be found after at least 30 minutes to one hour has passed since the spread of the fire began. For this reason, if the discovery of a fire is delayed, a situation may arise in which the garbage in the garbage pit must be burned. Therefore, from the viewpoint of fire prevention, the earlier the detection of the spread of fire types, the better. In order to prevent the fire, there has been an attempt to detect the surface temperature of the dust layer in the dust pit with an infrared thermometer and to detect the type of fire by increasing the detected temperature. However, the surface of the dust layer is large and the dust is large. Since there is a difference in the surface temperature of the dust layer depending on the quality, it is difficult to detect a local temperature change in the conventional equipment, and thus it is difficult to accurately detect the kind of fire. Therefore, the integrated facility for refuse incineration furnaces of the present invention solves the above-mentioned problems, and detects the spread of fires in the garbage layer at an early stage, thereby enabling the prevention of fires. The purpose is to provide equipment.

[0004]

[Means for Solving the Problems]

[First characteristic configuration] A first characteristic configuration of the integrated facility of the refuse incineration furnace according to the present invention for the above purpose is as follows. The point is that the detecting means is provided. [Effects of the first characteristic configuration] According to the first characteristic configuration, the temperature detection means in the dust layer provided on the bucket of the crane equipment comes into direct contact with the dust, so that the bucket is securely inserted into the dust layer. The temperature of dust below the dust layer surface can be detected. Therefore, since the change in the temperature in the dust layer can be detected sensitively, the expansion of the type of fire can be detected at an early stage. As a result, it has become possible to prevent fires in the integrated facilities of the refuse incinerator.

[Second Characteristic Configuration] A second characteristic configuration of the integrated facility of the refuse incinerator according to the present invention for the above purpose is the contact type refuse according to the first characteristic configuration. The in-layer temperature detecting means is disposed on the bucket such that the bucket of the crane equipment descends and the lower end of the bucket enters below the surface of the garbage layer so that the bucket can enter the garbage layer. . [Function and effect of second characteristic configuration] According to the second characteristic configuration, in addition to the function and effect of the first characteristic configuration, since the temperature detection means in the dust layer can enter the dust layer, it is ensured. The temperature below the dust layer can be detected. Therefore, a temperature change that does not appear on the surface of the dust layer can be detected, and early detection of a temperature change accompanying the spread of a fire type is facilitated. As a result, it has become possible to detect the spread of fire types in the garbage incinerator integrated facilities more quickly, thereby making it easier to prevent fires.

[Third characteristic configuration] A third characteristic configuration of the integrated facility of the refuse incinerator according to the present invention for the above purpose is a contact type refuse according to the second characteristic configuration. The layer temperature detecting means is constituted by a sheath-type thermocouple,
The thermocouple is protruded downward from the main body of the bucket and fixed thereto, and a protection cylinder surrounding the thermocouple is attached to the main body so as to be slidable in a longitudinal direction of the thermocouple, and the protection The present invention is characterized in that the main body is provided with an urging means for urging the cylinder so as to push the cylinder downward. [Function and Effect of Third Characteristic Configuration] According to the third characteristic configuration, in addition to the function and effect of the second characteristic configuration, a sheath-type thermocouple constituting the dust layer temperature detecting means is provided inside the dust layer. When the thermocouple enters, the sheath of the thermocouple can be prevented from being broken while the sheath of the thermocouple is in direct contact with dust. That is, since the protective cylinder is urged to be pushed downward by the urging means, the sheath is surrounded and protected by the protective cylinder until the sheath enters the dust layer,
Even if the bucket swings in the lateral direction, the lateral external force from the dust layer is received by the sheath, and the external external force from the dust layer is not directly applied to the sheath. In addition, since the protection cylinder is pushed up by the dust on the surface of the dust layer as the bucket descends, the sheath of the thermocouple fits into the dust layer under the surface of the dust layer while directly contacting the dust. Therefore, it is possible to detect a temperature change that does not appear on the surface of the dust layer while preventing damage to the dust layer temperature detecting means, thereby facilitating early detection of the temperature change due to the partial expansion of the type of fire. as a result,
It has become possible to detect the spread of fire types in the garbage incineration facility more quickly and to make fire prevention easier.

[Fourth characteristic configuration] A fourth characteristic configuration of the integrated facility of the refuse incineration furnace of the present invention for the above purpose is as described in claim 4 as the first characteristic configuration to the third characteristic configuration. In addition to providing a water discharging means for discharging water toward the dust layer in any of the above, when the temperature in the dust layer detected by the temperature detecting means in the dust layer exceeds a predetermined value, the temperature in the dust layer exceeding the predetermined value is detected. The present invention is characterized in that a temperature control mechanism in the garbage layer is provided so as to discharge water from the water discharging means toward the position. [Function and Effect of Fourth Feature Configuration] According to the fourth feature configuration, it is possible to discharge water toward a dust layer in a dust pit whose temperature is to be lowered at an early stage. That is, since the temperature control mechanism in the dust layer is provided, when the temperature in the dust layer exceeds a predetermined value, smoke rises from the surface of the dust layer, or water is discharged from the water discharging means before a flame is generated to remove the dust layer. Cooling makes it possible to prevent fires in the garbage pit. As a result, it has become possible to more easily prevent fires in the integrated facilities of the refuse incinerator.

[Fifth feature configuration] The fifth feature configuration of the integrated facility of the refuse incineration furnace of the present invention for the above purpose is as described in claim 5, the first feature configuration to the fourth feature configuration. Transporting the dust at a position where the temperature inside the dust layer is low to a position where the temperature inside the dust layer is low by crane equipment so that the temperature inside the dust layer detected in any of the above is equalized, or
The present invention is characterized in that a dust transport control mechanism is configured to instruct or control the replacement and transport of the dust so that the dust at the high temperature in the dust layer is transported to the low temperature in the dust layer. [Function and Effect of Fifth Characteristic Configuration] According to the fifth characteristic configuration, it is possible to suppress the temperature rise of the dust layer earlier. In other words, since the dust is replaced by the dust transport control mechanism and the temperature in the dust layer is made uniform, if the temperature in the dust layer rises despite the replacement of the dust, the position at which the temperature rise is detected. It can be determined that a fire is present below the area, and it is possible to detect the spread of the fire earlier than in the first to fourth feature configurations. As a result, it has become possible to reliably prevent fire in the integrated facilities of the refuse incinerator.

[Sixth feature configuration] The sixth feature configuration of the integrated facility of the refuse incineration furnace of the present invention for the above purpose is as described in claim 6, the first feature configuration to the fifth feature configuration. A dust surface temperature detection mechanism for detecting the surface temperature of the accumulated dust in any of the above-mentioned manners in a non-contact manner, so as to guide the bucket to a position where the dust surface temperature detected by the dust surface temperature detection mechanism is high. The point is that a dust transport control mechanism is configured. [Function and Effect of Sixth Feature Configuration] According to the sixth feature configuration, the bucket is guided to a position where the surface temperature of dust is high.
It becomes possible to detect an increase in the temperature inside the dust layer even earlier. As a result, it has become possible to more reliably prevent fire in the integrated facility of the refuse incinerator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an integrated facility for a refuse incinerator according to the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of an integrated facility of the refuse incineration furnace of the present invention. Garbage pit 1
Is provided with a garbage pit 1 adjacent to a garbage hopper 11 of a garbage incinerator 10 as in the conventional case (see FIG. 2).
Above the garbage pit 1, a crane facility 2 for introducing garbage accumulated in the garbage pit 1 from a garbage hopper 11 to a garbage incinerator 10 is arranged. Further, a water discharge gun 6A is provided as a water discharge means 6 on the side of the refuse pit 1 so as to discharge water toward the refuse layer.

As shown in FIG. 2, the garbage pits 1 are divided and managed in a grid pattern, and A, B, C, D, E, and F are sequentially arranged from the side away from the garbage incinerator 10. The area is divided vertically, and a, a,
b, c, d to q, r are divided into respective horizontal streets, and the section where the vertical street and the horizontal street intersect is set as a management unit (for example, the intersection section of the A vertical street and the f horizontal street is the Af section). And is managed for each section.) Based on the control by the transport control mechanism 7, the crane equipment 2 picks up and transports the debris near the surface of the debris layer in the debris pit 1 by the bucket 3, and exchanges the debris between the sections. This aims at homogenization of dust in the dust pit 1 as described in the section of the problem to be solved by the invention.

The crane equipment 2 is provided with a club 2b provided to reciprocate in the longitudinal direction of the girder 2a on the girder 2a running along the vertical street, and a hoisting device is provided on the club 2b. , The bucket 3 is hung on a wire. The bucket 3 is quickly lowered into the garbage pit 1 by the hoisting device of the club 2b, the claw 3c at the tip of the side plate 3b of the bucket 3 is fitted into the garbage layer, and the bucket 3 is wound up while holding the garbage. As shown in FIG. 3, the bucket 3 is a clamshell-type grab bucket, in which a bucket body 3a is hung from the hoisting device, and a pair of side plates 3b are swingably attached to the bucket body 3a. , An auxiliary cable 9B for relatively suspending the main body 3a
Is operated to open and close the side plate 3b. When the side plate 3b is lowered, the claw 3c at the tip portion is inserted into the dust layer in an open state, and when the side plate 3b is raised, the side plate 3b is rolled up in a closed state.

[0013] The crane equipment 2 is used for removing garbage from the garbage incinerator 10.
The transfer control mechanism 7 is not used except when the
Of the garbage layer in the garbage pit 1, the garbage is exchanged while mainly moving between a section having a high surface temperature and a section having a low surface temperature. The transport control mechanism 7 includes an infrared camera 4 serving as a dust surface temperature detecting mechanism 4 disposed toward the surface of the dust layer in the dust pit 1.
The image A is subjected to image processing, the image is divided into sections serving as the management units, and the surface temperature of the dust layer is detected for each section. Then, each section is ranked according to the surface heating of the garbage layer, the crane equipment 2 is controlled, and the garbage bucket 3 is preferentially guided to the section (for example, Bc) showing the highest surface temperature. When the dust is picked up, the dust is guided to a section (for example, El) showing the lowest surface temperature, and the dust is dropped into the section El. Next, the crane equipment 2 is controlled so that the garbage bucket 3 picks up the garbage in the surrounding section El where the garbage is dropped down, guides the garbage bucket 3 and the section Bc.
Let the garbage drop off. In this way, the section for guiding the dust bucket 3 from the transport control mechanism 7 is notified to the dust layer temperature control mechanism 8 while the surface temperature of the dust layer in the dust pit 1 is made uniform.

A sheath type thermocouple 5A is attached to the main body 3a of the bucket 3 as a dust layer temperature detecting means 5 so as to protrude downward from the main body 3a inside the bucket 3. A protective cylinder 5a surrounding the thermocouple 5A is attached to the main body 3a so as to be slidable up and down, and further includes a coil spring for urging the protective cylinder 5a to be pushed downward. The urging means 5b is connected to the main body 3
a. Therefore, when the bucket 3 is lowered and the claw 3c is fitted into the dust layer, the protective cylinder 5a urged downward from the main body 3a is moved downward under the urging means 5b by the resistance of the surface of the dust layer. The thermocouple 5A is pushed into the dust layer while being protected from the acting force of the dust in the lateral direction by the protective cylinder 5a. The temperature in the dust layer detected by the thermocouple 5A is transmitted to the temperature control mechanism 8 in the dust layer via the transmitter. For details, see FIG.
As shown in (b), the sheath-type thermocouple 5A fixed and attached downward to the center of the main body 3a of the grab type bucket 3 is vertically movable relative to the main body 3a.
It is mounted in a protective cylinder 5a which is mounted by being urged downward by a coil spring 5b. The bucket 3 is entirely suspended by a main rope 9A. Further, the main body 3a is suspended by an auxiliary rope 9B attached to the main body 3a by pivotally supporting a link mechanism and a main body 3a side plate 3b. By lowering the main body 3a, the side plate 3b is opened and closed. The side plate 3b tensions the auxiliary cable 9B, closes the main cable 3A by pulling up the main body 3a relatively to the main cable 9A, and relaxes the auxiliary cable 9B with the entire bucket suspended by the main cable 9A. The main body 3a is relatively lowered and opened. The protection cylinder 5a projects downward from the main body 3a when the bucket descends and surrounds the sheath of the sheath-type thermocouple 5A, and protects the sheath-type thermocouple 5A from a lateral force acting on the sheath due to dust caused by shaking of the bucket. When the bucket lowers and the protection cylinder 5a comes into contact with the surface of the dust layer, the protection cylinder 5a is relatively pushed up against the downward pushing force of the urging means 5b due to the resistance of the dust layer surface. Here, the sheath-type thermocouple 5A is exposed and pushed into the dust layer. At this time, since the side plate 3b of the bucket fits into the dust layer at the same time, the lateral swing of the bucket 3 is suppressed,
The acting force from the dust layer is prevented from laterally acting on the sheath of the sheath-type thermocouple 5A, and the sheath is not likely to break.

In the dust layer temperature control mechanism 8, the received dust layer temperature is set to a predetermined value (for example, 50).
If the temperature in the dust layer exceeds 50 ° C. in comparison with the temperature in the dust layer, the water discharge gun 6A is operated to discharge water toward the section in which the temperature exceeding the predetermined value is detected. For example, if the thermocouple 5A detects 60 ° C. when trying to pick up and remove dust in the section Bd, the 60 ° C. signal is sent to the dust layer temperature control mechanism 8 via a transmitter (not shown). . The temperature control mechanism 8 in the garbage layer recognizes from the signal from the transport control mechanism 7 that the garbage gacket 3 has picked up and garbage the garbage from the section Bd, judges from the received temperature value, and determines the water discharge gun 6A.
To the section Bd and open a water discharge valve (not shown).

Next, another embodiment of the present invention will be described. <1> In the above embodiment, the example in which the dust layer temperature detecting means 5 is constituted by the sheath type thermocouple 5A has been described, but a resistance wire type thermometer may be used instead. It is possible to use other semiconductor-type or hot-wire-type temperature detecting means, and the above-described effects can be obtained if the temperature detecting means is a contact type. <2> In the above embodiment, the sheath-type thermocouple 5A is used as the dust layer temperature detecting means 5 and the main body 3a of the dust bucket 3 is used.
From above, and the protection cylinder 5a urged downward so as to be able to move up and down is attached to the periphery of the protection cylinder 5a. The claw portion 3c may be exposed and attached to the claw portion 3c so that the temperature detection means 5 in the garbage layer enters the garbage layer and comes into contact with the garbage as the claw portion 3c fits into the garbage layer. . Further, a drive mechanism such as hydraulic pressure may be provided so that the in-dust layer temperature detecting means 5 is fitted into the dust layer. <3> In the above embodiment, the crane equipment 2 is shown as a club type which is automatically controlled by the transfer control mechanism 7. However, the crane equipment may be a man club type. On the other hand, the operation position may be instructed from the transport control mechanism 7. Regarding the operation position, the position in the girder direction and the position in the girder moving direction of the crane equipment may be used without using the section. <4> In the above embodiment, an example in which the temperature control mechanism 8 in the garbage layer automatically discharges water from the water discharge gun is shown. May be configured to discharge water. <5> In the above embodiment, an example is shown in which the dust surface temperature detection mechanism 4 is provided and the crane equipment 2 is controlled based on the detected dust surface temperature. However, the detection of the dust surface temperature is omitted. In addition, a fire may be predicted based on a temperature detection result by the garbage layer temperature detecting means 5 provided in the garbage bucket 3 while operating the crane equipment 2 in the conventional manner. <6> The configuration of the garbage bucket 3 is not limited to the illustrated one, and is not limited to a clamshell type grab bucket, and may be another configuration. In addition, any type of crane equipment used for other garbage crane equipment can be used. <7> In the above embodiment, the protection cylinder 5a urged downward by the urging means 5b so as to be able to move up and down around the sheath type thermocouple 5A.
Although the example which constituted by attaching was shown, the said protection cylinder 5a
The mounting method is not limited to this, and may be one that expands and contracts itself, and may be any protective means that retreats in contact with the surface of the dust layer. The urging means 5b is not limited to a coil spring, and may be urged downward by hydraulic pressure, air pressure, or the like. Furthermore, the dust layer temperature detecting means 5 itself may be attached so as to be able to move up and down. In this case, the garbage bucket 3 may not be biased, and may be provided with a pushing means for pushing itself into the garbage layer when the garbage bucket 3 reaches the garbage layer. For example,
As shown in FIG. 4, a temperature detecting means pushing mechanism 9 which can be pushed downward from the main body 3a of the garbage bucket 3 is provided.
The sheath type thermocouple 5A may be pushed downward by the fluid pressure cylinder mechanism 9a (see FIG. 4).
The fluid pressure cylinder mechanism 9a is operated as an actuator, and it is detected that the protection cylinder 5a urged downward by the urging means 5b is pushed up to the main body 3a (a detection means is not shown). ) To operate the hydraulic cylinder mechanism 9a.
In this case, it is more preferable that the fluid pressure cylinder mechanism 9a be operated so as to be pushed downward only while the protective cylinder 5a is in contact with the main body 3a.
