Description

The present invention relates to a temperature control device for animal and plant materials such as sewage sludge, food sludge, and food waste (hereinafter referred to as "compost raw materials"), a composting treatment facility, a thermometer for controlling compost raw materials, and a temperature control device for compost raw materials. Regarding management methods. Specifically, when controlling the temperature of compost raw materials, it is easy to install management equipment, and the temperature can be controlled by remote monitoring. The present invention relates to something that can reduce the burden and effort of a person (hereinafter referred to as "management worker").

BACKGROUND ART Conventionally, methods for producing compost have been carried out in which animal and plant materials such as food waste are used as raw materials and are decomposed by fermentation by aerobic microorganisms. The method for producing compost requires mixing the compost raw materials at a predetermined timing (hereinafter referred to as "cutting back"). By doing this, the compost raw materials are evenly mixed, supplying oxygen to aerobic microorganisms, promoting fermentation, and suppressing fermentation by anaerobic microorganisms that produce methane gas, etc.

By the way, it is known that during fermentation by aerobic microorganisms, the temperature of the compost raw material rises to about 60 degrees, and as the fermentation progresses, the temperature gradually decreases, and in order to continue and activate the fermentation, It is recommended to switch back when the temperature is trending down. For this reason, in composting processing facilities, it is common for management workers to periodically measure the temperature of compost raw materials in order to determine the timing of turning over.

However, carrying a thermometer and inserting it into the compost raw material every hour of every day to measure the temperature of the compost raw material is a very time-consuming task for the management worker. Furthermore, since the temperature of the compost raw material during fermentation increases as described above, the manager who is performing temperature measurement work is exposed to hot air. In addition, compost raw materials in the early stages of composting have a strong odor. The generation of hot air and odor is particularly noticeable in the summer. In other words, the work of measuring the temperature of compost raw materials performed under such conditions not only takes time and effort for the worker, but also places a large physical and mental burden on the worker.

Therefore, as a means to reduce the above-mentioned work load, a method for producing compost as described in Patent Document 1 below, for example, has been proposed. The method for producing compost involves placing compost raw materials in an aging tank with ventilation piping arranged at the bottom, and oxidizing and decomposing them with microorganisms while feeding air into the compost raw materials through the ventilation piping, and simultaneously fermenting them to produce compost. This method measures the temperature of the compost raw material in the aging tank periodically or continuously, and adjusts the current amount of air to be sent into the compost raw material via the ventilation pipe to the current temperature of the compost raw material. The amount of air is controlled to be the amount of air obtained by subtracting, from the proportional amount of air, the amount of unnecessary air that occurs as the remaining immature components in the compost raw material decreases.

In the method for producing compost, it is disclosed that the temperature of the compost raw material is measured by inserting a temperature sensor into a part of the compost raw material that is not easily influenced by external factors in terms of temperature in the aging tank (patented). According to this method (claim 3) of Document 1, the management worker is freed from the trouble of transporting the thermometer and inserting it into the compost raw material.

Japanese Patent Application Publication No. 2003-146783

However, in the compost production method described in Patent Document 1, although the management worker is freed from the trouble of transporting the thermometer and inserting it into the compost raw material by fixing the temperature sensor, he or she does not have to regularly visit the compost raw material storage area. However, it is difficult to say that the physical and mental burden of being exposed to heat and odors is alleviated.

The present invention was devised in view of the above points, and when controlling the temperature of compost raw materials, it is easy to install management equipment, and the temperature can be controlled by remote monitoring. The purpose of the present invention is to provide a temperature control device for compost raw materials, a composting processing facility, a thermometer for managing compost raw materials, and a temperature control method for compost raw materials, which can reduce the burden and effort of management workers during work. shall be.

A sheathed thermocouple is preferably used as the "temperature measuring section" from the viewpoint of product life, heat resistance, and mechanical strength, but it is not limited to this, and examples include an infrared measuring structure and a resistance measuring structure. can also be adopted.

The "predetermined length" is preferably long enough to reach a predetermined depth in the center direction of the target compost material in the height direction, for example, 30 cm or more and 200 cm or less. It is not limited, and can be changed depending on the amount of compost raw material (height to pile up, etc.). In addition, if it is less than 30 cm, it is not preferable because the temperature can only be measured near the surface layer of the compost raw material, whereas if it exceeds 200 cm, it is not preferable because it may cause problems in handling and storage.

The compost raw material management thermometer has the above-mentioned signal converter in its main body, so that it can convert an analog signal related to temperature information of the compost raw material measured by the temperature measuring unit into a digital signal. Further, since the main body section has the above-mentioned transmitting section, the converted digital signal (temperature information of the compost raw material) can be transmitted to the outside of the machine by wireless method. Since the main body includes the above-mentioned battery, power is supplied to the transmitting section and the signal converting section, and the transmitting section and the signal converting section can be driven.

The main body has a casing formed of a watertight and airtight peripheral wall, so it can house the signal converter, transmitter, and battery, and protects the built-in signal converter from moisture, corrosive gas, etc. can do. Further, since the casing is connected in such a manner that the temperature measuring part protrudes in a predetermined direction, the main body part can be exposed outside the compost raw material in a manner in which the temperature measuring part is inserted into the compost raw material. Furthermore, since the casing and the temperature measurement section are connected, the temperature information measured by the temperature measurement section can be directly transmitted to the signal conversion section inside the casing.

Since the casing has an opening and a lid, the main body normally protects the built-in signal converter etc. from moisture and corrosive gas when the lid is closed, and when the battery is unable to supply power, The device can be used continuously by opening the lid and inserting and removing batteries through the same opening to replace them.

Furthermore, by having the above-mentioned covering part, the main body part can cover part of the casing surface including the lid part, or the entire area of the casing surface, in a watertight and airtight manner. Thereby, in addition to the protection function provided by the casing itself from moisture, corrosive gas, etc., the protection function provided by the covering portion can be added.

The relay device included in the compost raw material temperature management device can receive the digital signal transmitted from the compost raw material management thermometer to the outside by having the above-mentioned receiving section. Since the relay device has the above-mentioned Internet communication section, the digital signal received by the reception section can be wirelessly transmitted outside the aircraft via the Internet line.

According to the compost raw material temperature control device of the present invention, it is only necessary to insert the above-mentioned compost raw material management thermometer into the compost raw material, and there is no need to route power cables or communication cables, so installation work is easy. In addition, since the relay device has a relatively simple structure, it can be miniaturized and installation work is easy. The measured temperature of the compost raw material is sent wirelessly from the compost raw material management thermometer to the relay device, and can be confirmed from the relay device via the Internet line on the information communication terminal used by the management worker ( In other words, temperature control via remote monitoring is possible).

By the way, in the casing of the present invention, the boundary part between the first casing member and the second casing member appears on the side surface due to its structure, but by attaching the band, the boundary part and its vicinity are covered and moisture is removed. This makes it difficult for corrosive gases to enter. In addition, by covering the side surface area of the casing including the band with a shrink material, it becomes difficult for moisture, corrosive gas, etc. to enter. In other words, the covering portion is a double layer, and the effect of inhibiting the infiltration of moisture, corrosive gas, etc. is further improved.

In addition, even when performing maintenance by separating the first casing member and the second casing member, the casing is opened by cutting the band and shrink material (sometimes only the shrink material is cut), and after maintenance is completed, The work is easy as all you have to do is re-wrap the band, shrink the shrink material and reseal.

Further, when the band is an annular band that is stretchable and has watertightness and airtightness, the work of attaching the band is easy and quick, and the workability is further improved. Since the band adds watertightness and airtightness to the first coating layer, it further reduces the possibility of moisture or corrosive gases entering the casing, and protects components such as the signal conversion unit built into the casing. can be achieved.

[Temperature control method for compost raw materials]
In this embodiment, the temperature control method for compost raw materials is performed as follows.

(1st step: installation process)
The procured compost raw material C is carried into the storage section 10 of the composting treatment facility 1, piled up, and stored. The temperature measurement part 210 of each management thermometer 21 is inserted into the compost raw material C in the storage part 10 (inserted). As shown in FIGS. 1 and 2, the three control thermometers 21 are arranged at the rear, center, and front sides of the storage section 10.

When the management thermometer 21 is operated, temperature information (analog signal) inside the compost raw material C can be obtained. In order to accurately measure the temperature inside the compost raw material C, it is recommended that the temperature measuring part 210 of the management thermometer 21 be inserted as deeply as possible toward the center of the compost raw material C in the height direction.

In this embodiment, the number of control thermometers 21 is three, but the number is not limited to this. For example, the number may be one or two, or there may be four or more. good. The number of management thermometers 21 and their arrangement (insertion positions) can be appropriately selected depending on the amount of compost raw material C, the width of the storage section 10, and the like.

(Second step: management process)
The analog signal related to the above-mentioned measured temperature information is converted into a digital signal by the signal converter 213 built in the main body 211 of each management thermometer 21. This digital signal is then wirelessly transmitted to the outside of the machine by the transmitter 214.

(3rd step: management process)
The above-mentioned digital signal transmitted from each management thermometer 21 is received by the receiving section 221 of the relay device 22, and the received digital signal is transmitted via the Internet communication section 222 of the relay device 22 via the Internet line. and transmit it to the outside of the aircraft using a wireless method.

Then, the digital signal is received by the information communication terminal D1 etc. used by the work manager (user) via the Internet line, and the compost raw material C based on the received digital signal is sent to the web browser etc. of the information communication terminal D1 etc. The temperature will be displayed. The work manager visually checks the screen of the information communication terminal D1, etc., and confirms the temperature of the compost raw material C. After checking the temperature, the management worker turns the compost raw material C depending on the temperature of the compost raw material C, or uses the blower B shown in FIG. Air may be supplied from B1 to the compost raw material C during fermentation.

(effect)
The effects of the composting treatment facility 1 including the temperature control device 2 and the temperature control system 3 for compost raw materials will be explained.

The composting treatment facility 1 is equipped with the storage section 10, so that the compost raw material C can be stored as shown in FIG. A large amount of compost raw material C can be composted simultaneously in the plurality of storage units 10. At this time, each storage section 10 is partitioned by walls on both sides and the back (see Fig. 1), so that when processing many compost raw materials C, the degree of maturity (degree of progress of fermentation) is different. The compost raw materials C are not mixed, and compost at an appropriate maturity level can be produced for each storage section 10.

In addition, each storage section 10 is divided by concrete walls, so that it is less likely to corrode than walls made of wood or iron, and has a structure that does not require equipment renewal over a long period of time. Since each storage section 10 has a structure with the front and top open (see FIG. 1), it is possible to release heat and steam generated during fermentation.

Each storage section 10 has a structure with the front side, which is the passage side, open (see Fig. 1), so that the compost raw material C can be carried into the storage section 10 by a work vehicle such as a wheel loader, and the aged compost can be carried out. can do. A management worker can enter the storage section 10 from the front when necessary, such as installing the management thermometer 21, and can also easily perform visual inspection from the passage 11 (i.e., outside the storage section 10). .

The temperature measurement part 210 of each management thermometer 21 is inserted (inserted) into the compost raw material C stored in the storage part 10 at a predetermined depth and installed. Thereby, temperature measurement can be performed.

A signal (analog signal) of temperature information of the compost raw material C measured by the temperature measuring section 210 is transmitted to the signal converting section 213, and this signal is converted into a digital signal by the signal converting section 213. The converted digital signal (temperature information of the compost raw material) is transmitted to the outside of the machine by the transmitter 214 using a wireless method (ESB communication protocol). The signal converter 213 and the transmitter 214 are powered by a battery 215 built into the main body 211 and driven.

By adopting the ESB communication protocol for wireless communication with the relay device 22, each management thermometer 21 is capable of intermittent communication over a long period of time, and consumes less power. There is no need for periodic battery replacement.

Since the casing 212 has the above-described structure, it protects the built-in signal converter 213, transmitter 214, and battery 215 from moisture, corrosive gas, and the like. Furthermore, since the casing 212 is connected to the temperature measuring section 210 in the manner described above, the main body section 211 can be exposed outside the compost raw material C when the temperature measuring section 210 is inserted into the compost raw material C. . Furthermore, since the casing 211 and the temperature measurement section 210 are connected, the temperature information measured by the temperature measurement section 210 can be directly transmitted to the signal conversion section 213 inside the casing 211.

Moreover, since the casing 211 has the above-described structure, the signal converting section 213, the transmitting section 214, and the battery 215 are placed inside the first casing member 212a through the upper opening, and the second casing member 212b is installed inside the casing 211. 1. It is sufficient to simply close (cover) the upper opening of the casing member 212a, resulting in good workability. Furthermore, maintenance such as replacing the battery 25 or replacing the board can be performed simply by attaching and detaching the second casing member 212b, which is the lid, so that the workability during maintenance is also good.

Since the covering portion 212c of the casing 211 has a double layer structure including the first covering layer 212d and the second covering layer 212e described above, the effect (protective function) of preventing moisture, corrosive gas, etc. from entering is further improved. are doing.

The first covering portion 212d is configured by stretching the above-mentioned rubber band (the above-mentioned band) and attaching it so as to overlap the boundary portion of the side surface of the casing 211. The second covering section 212e is formed by placing a shrink material on the side surface of the casing 211 and heat-shrinking the shrink material long enough to cover the side surface area, upper surface, and part of the lower surface (near the outer edge) of the casing 212. Ru.

Note that when performing maintenance by separating the first casing member 212a and the second casing member 212b, the covering portion 212c can be removed by cutting only the shrink material or by cutting both the rubber band and the shrink material. I do. Note that if only the shrink material is cut, the rubber band can be stretched and removed, and the rubber band can be reused. On the other hand, if both the rubber band and the shrink material are cut, the rubber band cannot be reused and must be replaced, but as mentioned above, the battery 215 of the control thermometer 21 has a long life, so the rubber band has deteriorated. In many cases, it is better to replace the rubber band during maintenance.

The relay device 22 includes the above-mentioned receiving section 221 and thereby receives the digital signal transmitted from each management thermometer 21 to the outside of the machine. Then, the Internet communication section 222 of the relay device 22 transmits the digital signal received by the reception section 221 to the outside of the aircraft by wireless method via the Internet line. In addition, in this embodiment, the power supply of the receiving section 221 is structured to use a shared line of RS485 plus power supply, so that the receiving section 221 does not require a power supply (AC adapter) and is installed inside the housing 220. wiring can be simplified.

According to the composting processing facility 1 (including the temperature control device 2) and the temperature control system 3 for compost raw materials, it is only necessary to insert each control thermometer 21 into the compost raw material C, and there is no need to route power cables or communication cables. Therefore, installation work is easy. In addition, since the relay device 22 has a relatively simple structure, it can be miniaturized and installation work is easy. Then, the measured temperature of the compost raw material is sent from each management thermometer 21 to the relay device 22 by wireless method, and from the relay device 22 via the Internet line to the information communication terminal D1 etc. used by the management worker. You can check it.

In addition, the management worker may turn over the compost raw material C depending on the temperature of the compost raw material C, or use the blower B shown in FIG. , air may be supplied to the compost raw material C during fermentation.

In other words, maintenance workers are able to manage temperatures by remote monitoring during temperature control work, freeing them from the task of regularly visiting the storage area to check the thermometer, and also being able to perform maintenance tasks during equipment installation and maintenance. Since they are not exposed to heat or odors except when they are working, the physical and mental burden and effort are greatly reduced.

There is no intention to exclude terms or expressions that are equivalent to some of them. Further, it goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
