[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a soot processing machine for processing soot such as raw garbage.
[0002]
[Prior art]
A conventional soot processor will be described with reference to FIG.
[0003]
FIG. 12 is a schematic configuration diagram of a conventional hot air heating type soot treating machine, wherein 1 is a soot treating machine body, 2 is a soot treating container, and 3 is a heater for heating and drying the soot. Yes, 4 is a drying fan for blowing air heated by the heater 3 to the soot in the processing container 2, 5 is a stirring blade for stirring the soot provided in the processing container 2, and 6 is A cooling fan for cooling the inside of the main body 1, 7 is a temperature sensor for detecting the temperature in the processing container 2, 8 is an exhaust passage for discharging the air in the processing container 2, and 9 is water vapor generated from the soot 10 is a catalyst provided on the exhaust passage 8 for deodorizing the odor generated from the soot in the processing container 2 during the soot treatment process.
[0004]
An end sensor 11 is attached to the condenser 9 on the exhaust passage 8 and detects the temperature of the exhaust gas containing water vapor through the condenser 9. A tank 12 stores water generated from the soot. , 13 is a driving means for driving the stirring blade 5, and 14 is an outer container for installing the processing container 2. The exhaust passage 8 is also formed between the outer container 14 and the condenser 9.
[0005]
The operation of the heater 3 is controlled by a control means (not shown) based on inputs from the temperature sensor 7 and the end sensor 11.
[0006]
In the above configuration, the air heated by the heater 3 while being controlled by the control means so as to be a constant temperature by the temperature sensor 7 is sent to the processing container 2 by the drying fan 4 to heat the soot and to the stirring blade 5. By stirring and crushing the koji, the koji moisture is efficiently evaporated. Water vapor generated from the soot is discharged from the processing vessel 2 to the exhaust passage 8, and the condenser 9 is cooled by the cooling fan 6, whereby the water vapor is condensed in the condenser 9, and becomes water and enters the tank 12. Accumulate. The exhaust gas from which moisture has been removed passes through the catalyst 10 to be deodorized and is discharged out of the main body 1.
[0007]
When the soot is heat-treated and water vapor is continuously generated, the temperature detected by the end sensor 11 is greatly influenced by the temperature of the water vapor, and even if it is cooled by the cooling fan 6, a certain high temperature is maintained. When the soot dries out and the moisture in the exhaust runs out, the temperature goes down. The control means determines that the drying is finished when the state in which the input from the end sensor 11 is lower than the maximum temperature by a predetermined temperature or more continues for a predetermined time, and ends the heating by the heater 3.
[0008]
As a result, regardless of the amount and quality of the soot to be added, the drying end time can be detected and automatically ended.
[0009]
[Problems to be solved by the invention]
However, in the conventional slag processor, it is determined that the drying is finished when the state where the temperature has decreased by a predetermined temperature or more with respect to the maximum temperature continues for a predetermined time. Since the predetermined temperature does not decrease, it is not possible to detect the end, and the timing to start timing is advanced, so that it is not possible to accurately determine the end. Even if the detection temperature of the end sensor 11 changes due to changes in the state of the soot, such as cracking of the solid soot and the generation of water vapor from the inside of the cracked soot, the end time is optimal due to the change in the state However, there was a problem that the finished product in an optimal dry state may not be obtained.
[0010]
Also, regardless of the amount and quality of the soot that is thrown in, in the operation that automatically detects the end of drying and ends automatically, it is not possible to detect when idling without accidentally throwing in soot due to environmental conditions. There was a problem that there was a case.
[0011]
The present invention solves the conventional problems as described above, is accurate regardless of changes in the environment, etc., is finished in an optimal dry state, and is free of high precision idling that is not affected by the environment. The object is to provide a soot processing machine capable of detection.

[0018]

[0022]
【Example】
Example 1
A first embodiment of the present invention will be described below with reference to FIGS.
[0023]
In FIG. 1, 21 is a main body of a soot processing machine, 22 is a processing container which can be attached or detached from the main body 21, and accommodates soot inside. 23 is an outer container fixed to the main body 21 for installing the processing container 22, 24 is a stirring blade that is rotatably disposed in the processing container 22 and stirs and crushes the soot, and 35 is a stirring blade 24. It is drive means, such as a motor to drive. Reference numeral 25 denotes a cooling fan which is a cooling means for cooling the inside of the main body 21, 26 is an exhaust passage for discharging water vapor generated in the processing container 22, and 28 is exhausting the water vapor in the processing container 22 through the exhaust passage 26. , 29 is an exhaust port for discharging water vapor to the outside of the main body 21, 27 is a catalyst provided on the exhaust passage 26 to deodorize exhaust gas, and 30 is a processing vessel 22. Is a heater that heats the soot in the processing container 22, 33 is a drying fan that blows the heat generated by the heater 30 to the soot, and 31 detects the ambient temperature in the processing container 22. The heating sensor 30, the drying fan 33, the temperature sensor 31, and the heating control unit 37 in FIG. 2 constitute a heating / drying unit 38.
[0024]
An end sensor 32 is provided in contact with the exhaust passage 26 and detects the temperature of the exhaust gas in the exhaust passage 26. Further, reference numeral 39 in FIG. 2 denotes end determination means for detecting and storing the maximum value of the temperature of the exhaust passage 26 based on an input from the end sensor 32 and determining when to finish heating and drying.
[0025]
The operation of the above configuration is as follows. That is, when the power is turned on and the process is started, the heating control unit 37 turns on the heater 30 and starts up until the temperature information input from the temperature sensor 31 reaches the target temperature of 130 ° C. Based on the temperature information input from the temperature sensor 31, the heater 30 is turned off if it is higher than 130 ° C., is turned on if it is lower, and the heater 30 is controlled so that the temperature of the temperature sensor 31 is maintained at around 130 ° C. At this time, by operating the drying fan 33, warm air hits the soot in the processing container 22 to heat the soot.
[0026]
The heat generated from the heater 30 is conducted not only to the soot but also to each part of the main body 21, so that the cooling fan 28 performs cooling even during heating. Simultaneously with the heating of the soot, drying is promoted by crushing the soot with the stirring blade 24, the water vapor generated in the processing container 22 is sucked with the suction fan 28, and the exhaust port 26 is passed through the exhaust port 29. Drying is also promoted by forced exhaust.
[0027]
The attachment portion of the end sensor 32 in the exhaust passage 26 is made of a metal having a large specific heat, such as stainless steel. When the air in the processing container 22 starts to be exhausted through the exhaust passage 26, the temperature of the end sensor 32 rises. When the soot is heated to generate water vapor and the water vapor passes through the exhaust passage 26, the temperature of the attachment portion of the end sensor 32 is greatly influenced by the specific heat of the water vapor, and is 90 ° C. to 100 ° C. with respect to the cooling action of the cooling fan 25. The characteristics are maintained at a high temperature of ℃. When the soot is dried and the moisture contained in the air passing through the exhaust passage 26 disappears, the cooling effect by the cooling fan 25 increases, the temperature of the attachment portion of the end sensor 32 decreases, and when the moisture disappears, The characteristics are stable at a low temperature of 60 ° C. to 70 ° C. as compared to the temperature of the attachment portion of the end sensor 32 when it is generated.
[0028]
In the course of this series of drying processes, the end determination means 39 stores the temperature at time A at which the temperature detected by the end sensor 32 is the highest as the maximum value, as shown in FIG. Further, the end determination means 39 sets two predetermined values (hereinafter referred to as temperature determination values) for Δt1 and Δt2 with respect to the maximum value A such that Δt1 <Δt2, and T1 (Δ Two predetermined times (hereinafter referred to as determination times) of T1 (corresponding to t1) and T2 (corresponding to Δt2) are set so that T1> T2. Since the maximum value of the end sensor 32 is greatly influenced by the temperature of the water vapor, the value is almost stable even if the environmental temperature is different, but the temperature in a state where the water vapor is low is the environmental temperature or the like of the main body 21. Since it differs depending on the thermal characteristics, the characteristics shown by the solid line in FIG. 3 or the characteristics shown by the dotted line may be obtained. Now, assuming that the ratio of the characteristic indicated by the solid line is large, it is optimal for Δt2 and Δt2 in which the determination temperature is set large so as not to work quickly (undried) due to erroneous determination of the end determination means 39 due to noise or the like. The combination of the determination time T2 at which the end determination is finalized at time D, which is the heating end timing in a dry state, is used as a main determination value, and the temperature determination value Δt1 that can be determined by the characteristics indicated by the dotted line, and the end determination at time E If the combination shown in FIG. 3 is the characteristic indicated by the solid line in FIG. 3 with the combination of T1 such that is determined as the secondary determination value, the determination based on the main determination value is prioritized and the end determination is determined at time D, and the characteristic indicated by the dotted line In such a case, since the end determination is not fixed with the main determination value, the end determination is determined at time E with priority given to the sub determination value.
[0029]
When the end determination is confirmed, the heating control means 37 outputs an output to end the heating, and the heating control means 37 ends the heating at 130 ° C. by the heater 30 and ends the process after cooling by the cooling fan 25.
[0030]
The reason why the end determination determination time based on the sub-determination value is delayed (over-dried) from the main determination value is that, even if the determination temperature Δt1 taken small due to noise or the like is established, the opportunity to be canceled by T2 is increased. This is to prevent the processing from being finished at least in an undried state.
[0031]
As a result, the drying end time can be detected more accurately and in response to changes in environmental conditions and the like, and heating and drying can be automatically completed in an optimal drying state regardless of the amount of dust.
[0032]
(Example 2)
A second embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is provided about the same component as the said Example 1, The detailed description is abbreviate | omitted.
[0033]
In FIG. 4, reference numeral 42 denotes maximum value storage means for detecting and storing the maximum value based on temperature information of the end sensor 32. Reference numeral 41 denotes an initial determination temperature and determination time. If the maximum value of the value storage means 42 once falls below the maximum value-initial determination temperature and then becomes higher than the maximum value-determination temperature again during the determination time, the determination temperature and the determination time are updated and heated. It is an end determination means for determining the end time of drying.
[0034]
The operation of the above configuration is as follows. That is, as shown in FIG. 5, the end determination means 41 sets the determination temperature Δt1 and the determination time T1 as initial determination values when the operation of the main body 21 is started. In the course of processing, the maximum value storage means 42 stores the maximum value at the point A in FIG. 5 based on the temperature information of the end sensor 32, and the end determination means 41 inputs the maximum value, and this maximum value On the other hand, the determination of the determination time T1 is started from the point B when Δt1 decreases. In most cases, the characteristics shown by the dotted line in FIG. 5 are obtained, and the end determination is confirmed at the point D, and the heating by the heater 30 is stopped.
[0035]
During the determination of T1, depending on the timing of the stirring operation of the stirring blade 24, etc., a change occurs in the state of soot, such as a crack that has been dumped by the stirring blade 24 and water vapor comes out from the inside. As shown by the solid line in FIG.
[0036]
The end determination means 41 inputs temperature information from the end sensor 32, and when it rises from Δt1 at time C, it outputs to the maximum value storage means 42 to detect and store the maximum value again, and the maximum value storage means 42 At time E, the maximum value is updated. Since the drying is almost completed, and the amount of water vapor generated is smaller than that in the initial stage, it can be estimated that the maximum value appearing after time C is smaller than the maximum value at time A. Sets a determination temperature Δt2 (<Δt1) and a determination time T2 (<T1).
[0037]
The maximum value storage means 42 outputs the new maximum value stored at the time point E to the end determination means 41. The end determination means 41 determines the new maximum value at the determination temperature Δt2 and the determination time T2, and G At the time, it is determined that the drying is finished, and the heating control means 37 is output so as to finish the heating.
[0038]
As a result, even if there is a change in the state of the soot such as cracking of the soot that has become clumped during the end time determination, it is possible to finish the heat drying at the optimal end time commensurate with the additionally generated water vapor. it can.
[0039]
Example 3
A third embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is provided about the same component as the said Example 1, The detailed description is abbreviate | omitted.
[0040]
In FIG. 6, 61 is an end determination unit having two determination times of T <b> 1 and T <b> 2, and 62 is a time measurement unit that measures time according to an instruction from the end determination unit 61.
[0041]
The operation of the above configuration is as follows. In FIG. 7, the end determination means 61 is a characteristic indicated by a solid line during the determination of the first determination time (first predetermined time) T1 from the point B when Δt has decreased from the maximum value stored at the point A. As described above, when the detected temperature of the end sensor 32 rises above the temperature at the time B at the time C, the time is output to the time measuring means 62 so that the time measuring means 62 starts to time.
[0042]
The end determination means 61 inputs the time measured by the time measuring means 62, and the detected temperature of the end sensor 32 at the time when the second determination time (second predetermined time) T2 has elapsed is the time point B at the time measured. If the temperature is equal to or lower than the temperature, the heat is output to the heating control means 37 so as to end the heating at time E. In the case of a normal characteristic as shown by the dotted line, the temperature at the B time is not exceeded after the B time, so the heating is finished at the D time.
[0043]
T2 is set so that T2 <T1, and if the temperature information of the end sensor 32 when T2 has elapsed is greater than Δt, the end determination means 61 outputs to the time measuring means 62 so as to start again, The determination is made again when T2 has elapsed.
[0044]
As a result, heat drying can be completed at an optimal end timing commensurate with the amount of water vapor additionally generated due to cracking of the soot, and so on, such as cracking of the soot that the temperature change of the end sensor 32 becomes small. It is possible to cope with changes with high accuracy.
[0045]
(Example 4)
A fourth embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is provided about the same component as the said Example 4, The detailed description is abbreviate | omitted.
[0046]
In FIG. 8, reference numeral 81 denotes an end detection means for determining again the execution of heating and drying based on the temperature detected by the end sensor 32 even after it is determined that the heating has been completed.
[0047]
The operation of the above configuration is as follows. In other words, after the end determination means 82 has decreased by the determination temperature Δt after the B time with respect to the maximum value stored at the A time in FIG. 9, the determination time T1 has elapsed, the end determination is confirmed at the C time and the heat drying is performed. In the case of the characteristic indicated by the dotted line in FIG. 9, each part of the main body 21 is cooled by the cooling fan 25 for a preset time Tc from the point C, and all the processes are ended at the point E. .
[0048]
During Tc, when the temperature of the end sensor 32 becomes higher than the temperature at the time B again as shown by the solid line due to the change in the state of the soot, the end determination means 81 generates water vapor again in the processing container 22. It outputs to the heating control means 37 so that it may heat-dry for only predetermined time T2 from the time B. After heating and drying for a predetermined time T2, cooling by the cooling fan 25 is performed again for a time Tc, and all processing steps are completed at time G.
[0049]
Thereby, even if heat drying is finished once, moisture can be removed by changing the state of the cocoon, so that an optimal dry state can be obtained.
[0050]
(Example 5)
A fifth embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is provided about the same component as the said Example 1, The detailed description is abbreviate | omitted.
[0051]
In FIG. 10, 92 is a heating unit that heats the soot, and includes a heater 30 and a drying fan 33, and 91 is a heating control unit that controls the heating unit 92 according to the temperature detected by the temperature sensor 31. 93 is an empty determination means for determining the presence or absence of soot in the processing container 22, and 94 is a preheating time measuring means for measuring the time until the temperature detected by the temperature sensor 31 rises to the control temperature of the heating control means 91. is there.
[0052]
The operation of the above configuration is as follows. That is, when the power is turned on and the process is started, the heating control unit 91 turns on the heater 30 and starts up until the temperature information input from the temperature sensor 31 reaches 130 ° C. which is the target temperature. The power supplied to the heater 30 is controlled so that the temperature information input from the temperature sensor 31 is maintained at around 130 ° C.
[0053]
In addition, a control means (not shown) operates the catalyst 27 to prepare for deodorization, and when a predetermined time necessary for the catalyst 27 to fully exhibit the deodorizing ability has elapsed since the power is turned on, the cooling by the cooling fan 25 is performed. And the suction fan 28 is operated to start discharging the air in the processing container 22. At the same time, the heating control means 91 starts the operation of the drying fan 33 and starts blowing warm air to the basket. At this time, as shown between the time A and the time B in FIG. 11, the temperature detected by the temperature sensor 31 is temporarily lowered by the operation of the suction fan 28 and the drying fan 33. In a state where the drying fan 33 is operating, the temperature is maintained at around 130 ° C.
[0054]
The control means (not shown) starts the intermittent operation of the stirring blade 24 from the point C in FIG. 11 when the temperature in the processing vessel 22 that maintains around 130 ° C. becomes stable, and crushes and dries the soot. Start.
[0055]
The detection temperature of the end sensor 32 is 90 ° C. to 100 ° C. at normal temperature at the point D when the amount of water vapor generated from the soot is stabilized after pulverization drying is started, but no soot is contained in the processing container 22. In this case, since water vapor is not generated, the temperature is low (60 ° C. to 70 ° C.) as indicated by the dotted line in FIG. However, in consideration of environmental conditions and the like, there are cases where the vertical relationship of the temperature of the end sensor 32 at the time point D is reversed depending on whether or not wrinkles are included. For example, when a large amount of soot is introduced into the processing container 22 at an environmental temperature of −20 ° C., the temperature at the time D is about 70 ° C., and at the time D when the processing container 22 is empty at an environmental temperature of 40 ° C. The temperature may be about 75 ° C.
[0056]
The time from time A to time B varies depending on the environmental conditions, the amount of soot, etc. when soot is contained in the processing container 22, but when no soot is present, the moisture in the soot Since there is no heat taken away by vaporization, the temperature sensor 31 rises quickly. That is, if this time is long to some extent, soot is contained in the processing container 22, and only when this time is less than a certain time, it is determined whether or not soot is contained by detecting the temperature of the end sensor 32 at time D. By doing so, the accuracy of determination can be improved.
[0057]
The preheating time measuring means 94 starts time measurement when the heating control means 91 starts the operation of the drying fan 33, and as shown in FIG. 11, the temperature of the temperature sensor 31 is again set to 130 ° C. as shown at time B. When it reaches, the time is stopped by the input from the heating control means 91, and the time measured is output to the sky determination means 93.
[0058]
The empty determination means 93 has a determination time T and a determination temperature t as shown in FIG. 11, and if the time input from the preheating timing means 94 is equal to or greater than the determination time T, the stirring blade 24 No determination is made at time D when a preset time has elapsed since the start of intermittent operation, and the crushing and drying process is continued by assuming that soot is contained in the processing container 22.
[0059]
If it is less than the determination time T, the sky determination means 93 detects and stores the maximum value of the temperature input from the end sensor 32. If the maximum value at time D is greater than the determination temperature t, the processing container 22 is detected. It is determined that soot is contained therein and the pulverization and drying process is continued. If t or less, it is determined that the processing container 22 is operating empty, and the heating control unit 91 finishes heating. And the process is terminated after each part of the main body 22 is cooled by the cooling fan 25.
[0060]
When this is applied to the case where a large amount of soot is put into the processing container 22 at the environmental temperature of −20 ° C. and the case where the processing container 22 is empty at the environmental temperature of 40 ° C., the former time is determined from the determination time T. Since the latter becomes longer and the latter becomes shorter, only the latter is determined based on the temperature detected by the end sensor 32. In the former case, the crushing and drying process is continued.
[0061]
【The invention's effect】
According to the first aspect of the present invention, by providing a plurality of predetermined values and predetermined times corresponding to changes such as environmental changes, drying can be performed more accurately and in response to changes in environmental conditions. The end time is detected, and heating and drying can be completed automatically in an optimal drying state regardless of the amount of dust.
[0062]
According to the invention described in claim 2 of the present invention, when the value becomes equal to or greater than the value obtained by subtracting the predetermined value from the initial maximum value, the maximum value storage means thereafter updates the stored value of the maximum value of the temperature detected by the end sensor, Furthermore, since the end determination means updates the predetermined value and the predetermined time, even if a change in the state of the cocoon such as cracking of the cocoon that has become agglomerated during the determination of the end time occurs, additional moisture is generated. Heat drying can be completed at the optimal end time that meets the requirements.
[0063]
According to the invention described in claim 3 of the present invention, the end determination means determines the time when the time measured by the time measuring means ends the heating by the heating drying means based on the value of the end sensor when the second predetermined time has elapsed. Since it has been detected, it is possible to cope with changes in the state of the soot where the temperature change of the end sensor is small, and heat drying can be completed at an optimal end time corresponding to the additionally generated moisture.
[0064]
According to the fourth aspect of the present invention, when the temperature detected by the end sensor rises by a predetermined value or more during the cooling process, the end determination means extends the end timing and is again heated and dried by the heating and drying means. Therefore, even if heat drying is once completed, if moisture is generated again due to a change in the state of the soot, heat drying is performed again, so that an optimal dry state can be obtained.
[0065]
According to the invention described in claim 5 of the present invention, the empty judging means is a value inputted from the end sensor only when the time measured by the preheating time measuring means is less than a predetermined time, and whether the processing container has flaws or is empty. If it is determined that the soot is surely inserted for a predetermined time or more, an accurate sky determination can be performed under a wide range of conditions such as the environmental temperature.
