Description

Manure amount measuring device {APPARATUS FOR MEASURING AMOUNT OF HUMAN WASTE}

The present invention relates to a manure amount measuring device, and more specifically to the capacitance value of the collected manure collected in the manure collection tank of the manure collection transport vehicle to compensate the temperature value of the collected manure, the collection collected inside the manure collection tank It relates to a manure amount measuring device capable of accurately measuring the amount of manure.

In general, a manure collection vehicle that collects manure from a manure collection tank of a building or a house that does not have its own purification facility is discharged to a manure treatment plant. The manure collection vehicle completes the work by sucking and transporting the manure into the manure storage tank through the manure hose connected to the vacuum pump and discharging it to the manure treatment plant. In the conventional method of measuring the amount of manure collection, after collecting manure using the manure collection vehicle, the operator visually checks the level gauge installed at the rear of the manure collection vehicle, calculates the manure collection amount, and charges the fee according to the collection amount on site. Workers are receiving cash directly.

However, this method causes a lot of errors due to a large number of errors due to the visual measurement of the workers, and it is difficult to calculate the billing for each house when the two or more houses are continuously collected by one vehicle. In addition, during the collection work at the inclined work place, if the collection amount exceeds a certain amount, it is impossible to calculate, and it was inevitable to charge according to the subjective judgment of the worker.

Recently, in order to solve these problems, a system is installed to charge a bill based on the amount of water metered in the meter. The flowmeter uses an electromagnetic flowmeter because of the fluid characteristics of manure. Since the flowmeter calculates the flow rate and multiplies the cross-sectional area, there is a lot of concern that measurement errors may occur when an empty space occurs in the cross-sectional area. As a result, there were many cases in which fertilization was collected between the manure collector and the user.

In addition, in the case of using the electromagnetic flowmeter, the tube is empty at the time of collecting manure and the tube is not maintained, so the measurement is not accurate, and the air flows in at the time of collecting the manure. There was a problem that the measurement was not accurate because the state was difficult to maintain.

In addition, during the collection of manure, foreign substances are often introduced into the collection hose, and there is a problem that the measurement error increases because air is introduced during the removal of the foreign substances by applying a vacuum to remove the foreign substances.

In particular, in the winter, the collection hose is easy to freeze, and because the idling is to remove the ice in the frozen collection hose in the frozen state, there is a problem that the air flows into the collection hose, causing an error in the metering.

In addition, when the house to be collected manure is located on the inclined place, as the manure collection vehicle is inclined position, the manure collection tank is also inclined accordingly, there is a problem that an error may occur in the measurement of the manure collection amount.
