[0021] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 :

[0022] A waste oil recovery and metering silo comprises a silo body 1 having an oil storage inner cavity, a waste oil recovery injection assembly and a waste oil recovery and metering assembly being arranged on the top of the silo body 1, the waste oil recovery injection assembly comprising an annular cofferdam 2, wherein a plurality of injection ports communicating with the oil storage inner cavity are arranged in the annular cofferdam 2, the waste oil recovery and metering assembly comprising a controller 3 and a liquid level sensor 4, the liquid level sensor 4 being assembled on the silo body 1 and extending vertically to the oil storage inner cavity, the liquid level sensor 4 being electrically connected to the controller 3 and measuring the amount of waste oil injected into the oil storage inner cavity each time by means of a liquid level difference.

[0023] In this embodiment, a liquid level sensor 4 detects the amount of waste oil within the oil storage chamber 1 and transmits the data to a controller 3. When the waste oil is recovered, no pre-metering is required; it is directly injected into the oil storage chamber through the oil injection hole in the annular cofferdam 2. The annular cofferdam 2 prevents the waste oil from overflowing during injection. As the liquid level in the oil storage chamber rises, the liquid level sensor 4 monitors the liquid level in real time. After injection is complete, the difference in liquid levels before and after injection accurately measures the amount of waste oil injected into the oil storage chamber and displays it on the controller 3.

[0024] The controller 3 includes a controller housing, a control module for collecting and transmitting liquid level information, and a display screen for displaying liquid level information. The controller 3 may be a conventional liquid level controller 3 in the art.

Preferably, the oil filling holes 6 are distributed along the circumference and form a plurality of concentric circles. When pipeline injection is adopted, the oil filling pipeline is connected to the connecting pipe 5, and then the waste oil is injected into the oil storage cavity of the oil bin by using the pressure difference (such as using an oil pump). After the injection is completed, the oil filling pipe is removed from the connecting pipe 5. When pouring oil filling is adopted, the waste oil is poured directly into the annular cofferdam 2, and the waste oil flows into the oil storage cavity through the oil filling holes 6.

[0026] Preferably, in order to avoid the influence of the tubular injection port on the dumping type injection port, the tubular injection port is arranged at the edge of the annular cofferdam 2, and in order to facilitate the connection of the oil filling pipe, the tubular injection port is arranged at the front edge of the annular cofferdam 2; at the same time, the upper end surface of the connecting pipe 5 does not exceed the upper end surface of the annular cofferdam 2, and when the oil leaks from the connection of the connecting pipe 5, it can also flow into the oil storage cavity through the dumping type injection port; in order to make it easier for the dumped waste oil to enter the oil storage cavity, the dumping type injection port is arranged at the center of the annular cofferdam 2; preferably, the annular cofferdam 2 is preferably a rectangular structure.

[0027] In order to accurately measure the amount of waste oil, the liquid level sensor 4 is located at the center of the warehouse body 1; in order to facilitate injection operation and observation, the annular cofferdam 2 and the controller 3 are located in front of the liquid level sensor 4 and are arranged side by side.

[0028] This embodiment further provides a safer oil outlet structure: the tank body 1 is provided with an oil outlet connected to the oil storage cavity, and the oil outlet cover is provided with an oil outlet cover locked by a smart lock; the smart lock includes a fingerprint lock, a vein lock or an Internet-connected lock that is unlocked by scanning a QR code; when the oil in the tank body 1 needs to be extracted, it needs to be unlocked in a corresponding manner first.

[0029] In this embodiment, the liquid level sensor 4 is preferably a photoelectric liquid level sensor 4 .

[0030] Furthermore, the controller 3 is connected to the national solid waste platform through the Internet of Things, and the solid waste ledger can be automatically registered by transmitting data to the national solid waste platform.

[0031] In order to enhance the signal, a signal antenna 7 is provided on the top of the warehouse body 1, and the signal antenna 7 is electrically connected to the controller 3; further, the signal antenna 7 is connected to the warehouse body 1 through a suction cup base, a magnetic base or a snap-on base.

[0032] The bottom of the warehouse body 1 is provided with a plurality of legs for supporting the warehouse body 1, and the bracket can also use a structure such as rollers for easy movement; a pair of handles are provided on the side of the warehouse body 1, and the warehouse body 1 can be conveniently carried by the handles.
