BACKGROUND OF THE INVENTION
The present invention relates to a soot processing apparatus for drying soot and the like, and particularly relates to automatic control.
[0002]
[Prior art]
As a conventional wrinkle treatment apparatus, the one shown in FIG. 11 is generally known. This will be described below with reference to FIG.
[0003]
Reference numeral 1 denotes a processing container for storing an object to be processed such as garbage, 2 denotes a heating means such as a sheathed heater, and 3 denotes a temperature disposed on the bottom rear surface of the processing container 1 so as to detect the atmospheric temperature in the processing container 1. The sensor and heating means 2 are heated and controlled at a predetermined temperature by a control means (not shown) based on the output of the temperature sensor 3. A stirring blade 5 is driven by a drive motor 6. The stirring blade 5 and the drive motor 6 constitute a stirring means, and drying is promoted by stirring and pulverizing the workpiece.

Reference numeral 9 denotes an exhaust part for discharging gas, and reference numeral 8 denotes a catalyst provided in an exhaust path between the processing container 1 and the exhaust part 7.
[0004]
The operation of the above configuration is as follows.
[0005]
The drying process time is set as a predetermined time, the preheating step for raising the temperature of the heating means 2, and the temperature of the heating means 2 is controlled to be controlled at a predetermined temperature based on the output of the temperature sensor 3 by the control means. The process is shifted at every elapse of a predetermined time in the order of a drying process for stirring and pulverizing an object, discharging the gas by the suction fan 7 and heating and drying, and a cooling process for cooling the apparatus and the object to be processed by the suction fan 7. To perform a series of processing. During processing, gas (including water vapor) generated in the processing container 1 passes through the catalyst 8 to remove odor components and is discharged from the exhaust unit 7.
[0006]
[Problems to be solved by the invention]
In this type of conventional paddy processing equipment, the drying process time is set to a predetermined time, so when the amount of garbage is small, it becomes overdried and the garbage is burnt, and conversely, when the amount of garbage is large, There is a problem that the garbage is undried and the dry state of the garbage differs depending on the amount of the garbage put into the processing container.
[0007]
Although it is also known that automatically determines the end of drying, the heating temperature is automatically controlled because the heat capacity of the object to be processed decreases due to the decrease in the amount of moisture as drying by heating proceeds. However, there is a problem in that the determination accuracy varies due to, for example, the object to be processed being burnt on the processing container, and the drying state is different.
[0008]
An object of the present invention is to solve these conventional problems, and to provide a high usability soot processing apparatus that has a good dry state and automatically finishes drying.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a processing container for storing a processing object, a heating means for heating and drying the processing object, a processing object temperature sensor for detecting the temperature of the processing object, and the processing object. Control means having an automatic control function for judging the temperature and drying time of the object via the output of the object temperature sensor, the control means changing the amount of power supplied to the heating means in multiple stages It controls the heating temperature of the product and determines that the time when the predetermined power supply continues for a predetermined time or more is the end of drying , thereby suppressing the temperature of the workpiece to fluctuate lower. In addition, since the end point is automatically determined, it is possible to remove water appropriately regardless of the amount of the object to be processed .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As in the first aspect of the invention, by determining the time when the predetermined power supply continues for a predetermined time or more as the end of drying, it is possible to suppress the temperature of the workpiece to fluctuate lower, Since the end point is automatically determined, appropriate moisture removal can be performed regardless of the amount of the object to be processed.
[0011]
【Example】
( Reference Example 1)
Hereinafter, Reference Example 1 of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the same component as a prior art example, and the detailed description is abbreviate | omitted.
[0012]
In FIG. 1, reference numeral 4 denotes a first temperature sensor (hereinafter referred to as a “treatment object temperature sensor”) disposed on the bottom back surface of the treatment container 1 so as to detect the temperature of the treatment object in the treatment container 1. An output corresponding to the temperature is sent to the control means 11 (FIG. 2) as an electric signal. The control means 11 controls the heating means 2, the suction fan 7, the display, the drive motor of the stirring means, etc. A sensor (hereinafter referred to as an exhaust temperature sensor) 10 is attached to an exhaust path between the processing vessel 1 and the exhaust unit 9 to measure the exhaust temperature and to output an electric signal according to the detected temperature as shown in FIG. To the control means 10.
[0013]
The operation of the above configuration is as follows.
[0014]
When performing the drying process, the processing container 1 is heated by the heating means 2 as in the conventional example, whereby the object to be processed is heated to generate water vapor, which is sucked and exhausted by the suction fan 7. At this time, on / off control is performed from the control unit 11 to the heating unit 2 in accordance with the output of the workpiece temperature sensor 4, and the workpiece is controlled in the temperature range indicated by E in FIG. Is done.
[0015]
Further, the output of the exhaust temperature sensor 10 shows a temporal change as shown in FIG. This is because it is provided in the exhaust path and is due to the following reason. When the heating means 2 starts heating the object to be processed at time 0 and exhausted by the suction fan 7, the exhaust temperature gradually increases as the temperature of the object to be processed increases (from time 0 to A).
[0016]
During the time A to B, the temperature of the object to be processed reaches almost the set temperature, a lot of water vapor is generated, and the exhaust gas contains a large amount of water vapor. After time B, the drying of the object to be processed proceeds considerably, the generation of water vapor peaks, and the water vapor contained in the exhaust gas gradually decreases, so that the output voltage of the exhaust gas temperature sensor 10 gradually decreases.
[0017]
When the output voltage peak P of the exhaust temperature sensor 10 is lowered by D as shown in FIG. 3 (time C), the set temperature of the object to be processed is lowered from E to F until the control means 10 is heated. 2 is controlled.
[0018]
( Reference Example 2)
Next, Reference Example 2 of the present invention will be described with reference to FIG. In addition, since it is the same as that of the said reference example 1, the same code | symbol is provided to the same component and the detailed description is abbreviate | omitted.
[0019]
The operation of the control means in this reference example is as follows.
[0020]
As shown in FIG. 4, the same operation as in Reference Example 1 until time C, F output of the exhaust gas temperature sensor 10 is above reference example 1 and changes in the same manner, from the setting temperature E of the object at time C After changing to, the output of the exhaust temperature sensor 10 further decreases.
[0021]
Eventually, the influence of the change of the set temperature from E to F disappears, and the output of the exhaust temperature sensor 10 decreases less. At this time, the generation of water vapor has already been reduced compared to the peak time, and the drying process can be almost completed. Therefore, if the change H ′ in the output of the exhaust temperature sensor 10 is smaller than H during the predetermined time J, it is determined that the drying process has ended. Let
[0022]
( Reference Example 3)
Next, Reference Example 3 of the present invention will be described with reference to FIGS. In addition, since it is the same as that of the said reference example 1, the same code | symbol is attached | subjected about the same component and the detailed description is abbreviate | omitted.
[0023]
The operation of the control means in this reference example is as follows.
[0024]
When the control unit 11 controls the heating unit 2, for example, as shown in FIG. 5, the energization for one cycle is cut and the power supply to the heating unit 2 is controlled. In this example, since one cycle is cut out of five cycles, the supplied power is about 64%. Similarly, by adjusting the ratio of the cycle to be turned on and the cycle to be turned off, an arbitrary amount of power can be supplied. The amount of power to be supplied can also be controlled by phase control that controls the conduction angle within one cycle.
[0025]
By controlling the amount of power supplied to the heating means 2 in this way, the output of the workpiece temperature sensor 4 is supplied to the heating means 2 according to how far the set temperature E or F of the workpiece is separated. It is possible to control the power supply amount so that the output value of the workpiece temperature sensor 9 becomes a value very close to the set temperature of the workpiece. Thereby, the effect of changing the set temperature from E to F can be obtained more greatly.
[0026]
(Example 1 )
Next, Embodiment 1 of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the same component as the said reference example 1, and the detailed description is abbreviate | omitted.
[0027]
As shown in FIG. 7, the workpiece temperature sensor 4 is disposed on the bottom rear surface of the processing container 1 so as to detect the temperature of the workpiece in the processing container 1, and an output corresponding to the detected temperature is an electrical signal. As shown in FIG. 8, the control means 12 controls the suction fan 7 and the drive motor 6 as well as the amount of power supplied to the heating means 2. The method for supplying power to the heating means 2 may be the same as that in Reference Example 3 as shown in FIG.
[0028]
The operation of the above configuration is as follows.
[0029]
In order to control the heating means 2 at the set temperature L shown in FIG. 9, the control means 12 supplies power as shown in FIG. That is, when the output of the workpiece temperature sensor 4 is extremely low with respect to the set temperature L, 100% power is supplied, and the power supply amount is controlled to decrease as the difference decreases.
[0030]
Further, when the difference is almost eliminated, the power supply amount is set to a predetermined power supply amount P%, and even if the output of the workpiece temperature sensor 4 exceeds the set temperature L, the predetermined power supply amount P% is supplied. Acts like
[0031]
Thereby, the temperature of the object to be processed is stabilized at a relatively high temperature with respect to the set temperature.
[0032]
Needless to say, the predetermined power supply amount P% may vary depending on the configuration of the implementation, but it is appropriate to be about 10% to 30%. If it is higher than this, there is a risk of burning of the object to be processed, which is lower than this. And it becomes difficult to obtain the intended effect.
[0033]
(Example 2 )
Next, Embodiment 2 of the present invention will be described with reference to FIG. In addition, since it is the same as that of the said Example 1 , the same code | symbol is provided to the same component and the detailed description is abbreviate | omitted.
[0034]
The operation of the control means 12 in this embodiment is as follows.
[0035]
As shown in FIG. 10, until time R, the amount of power supplied to the heating means 2 according to the output of the workpiece temperature sensor 4 is lower than the predetermined power supply amount P% by the same operation as in the first embodiment. As in Example 1 above.
[0036]
During this time, moisture evaporates from the object to be treated and is discharged as water vapor, and the specific heat of the object to be treated decreases due to the decrease in moisture, and the amount of power supplied to the heating means 2 tends to gradually decrease.
[0037]
Eventually, the power supply to the heating means 2 is sufficient with the minimum P%, so if the power supply amount is P% for a predetermined time Q, it can be determined that the drying process is finished.
[0038]
【The invention's effect】
By the present invention lever can be set to a temperature of the object to be processed is increased, it is possible to early drying process, so determining automatically end, Ya lack dried regardless of such amount of the object to be treated Appropriate drying treatment without burning can be performed, and electric power can be used efficiently.
