Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a composting device.

(b) Conventional technology Composting equipment is a device that puts raw materials into a fermenter and ferments them to make compost. In order to obtain compost of excellent quality, it is necessary to Accurate control of the amount is required. However, in conventional composting equipment, the amount of raw materials input is not accurately controlled, and the amount of raw materials brought in by truck is determined by the amount that is sorted and removed in the pretreatment process leading to the fermentation tank. The approximate amount of input was only estimated by subtracting the amount of leachate from the raw materials that escaped during the process.

(c) Problems to be solved by the invention However, in the above-mentioned composting equipment, it is necessary for an operator to constantly monitor the status of inputting raw materials, and there is also a need to measure the amount that has been sorted and removed. A great deal of effort and time will be expended,
However, there was a problem in that the input amount could not be controlled very precisely. The present invention aims to solve these problems.

(d) Means for Solving the Problems The present invention solves the above problems by electrically measuring the weight of raw materials introduced into a fermenter. That is, the composting apparatus of the present invention includes a measuring punching plate placed at a position where the raw materials put into the fermenter are deposited, and a measuring punching plate that is supported from the bottom and outputs an electric signal according to the weight of the raw materials. It has a load cell that generates electricity.

(e) Action The raw materials put into the fermenter are deposited on the measuring punching plate. The load cell installed on the bottom of the measuring punching plate is
Converts the force due to the weight of the raw material into an electrical signal. This electrical signal is sent to, for example, a recorder, and the recorder records the input weight based on the electrical signal. Therefore, the amount of raw material input can be confirmed without constant monitoring or calculation, so the amount of raw material input can be accurately controlled.

(f) Example FIG. 1 shows an example of the present invention. The fermenter 10 is provided with a curved measuring punching plate 14a. Measuring punching plate 14a
is arranged at a position where the raw material 16a is input from the input conveyor 15. A flat punching plate 14b is provided in a portion of the fermenter 10 other than the bottom portion where the measuring punching plate 14a is provided. The measuring punching plate 14a and the punching plate 14b are independent, and the measuring punching plate 14a is supported by the fermenter 10 via load cells 18 and 19, as described later, and the punching plate 14b is supported by the fermenter 10. directly supported. A ventilation chamber 20 is formed in the lower part of the measuring punching plate 14a and the punching plate 14b. Fermenter 1
A stirrer 12 is provided at the top of the fermenter 10 so as to be movable in the longitudinal direction of the fermenter 10. The stirrer 12 has a stirring mechanism 12a capable of stirring a raw material 16a and a raw material 16b. The lower surface of the measuring punching plate 14a is supported by a plurality of load cells 18 and 19 fixed to the bottom of the fermenter 10. The load cells 18 and 19 always send electrical signals to the cable 21 according to the weight of the raw material 16a deposited on the measuring punching plate 14a.
and 22 to the recorder 24. Recorder 24
can record the input amount (weight) of raw materials based on electrical signals sent from load cells 18 and 19.

Next, the operation of this embodiment will be explained. Raw material 16b
, the material input from the input conveyor 15 onto the measuring punching plate 14a in the fermenter 10 is stirred by the stirring mechanism 12a of the agitator 12 and moved toward the discharge section at the right end of the fermenter 10 in the figure. It is what was done. Due to the movement of the raw material by the agitator 12, after a predetermined period of time, there will be no raw material on the measuring punching plate 14a. Next, a new raw material 16a is introduced from the input conveyor 15 and deposited on the measuring punching plate 14a. An electrical signal corresponding to the weight of the raw material 16a deposited on the measuring punching plate 14a is obtained by the load cells 18 and 19, and this electrical signal is sent to the recorder 24 via cables 21 and 22 and recorded. . Therefore, by looking at the record on the recorder 24, the operator can immediately confirm the amount of raw material input without performing any calculations. Furthermore, this result can be fed back to, for example, the pretreatment process to control the input amount so that it is always optimal, so that compost of excellent quality can be produced through automatic operation.

(G) Effects of the Invention As explained above, according to the present invention, the weight of the raw material input into the fermenter is measured by converting it into an electric signal, so it is possible to always accurately check the input amount. can do.
