AI Technical Summary

Technical Problem

Existing oil separators lack effective means of monitoring the oil layer, which can lead to oil overflow when the oil layer is too thick, resulting in resource waste and blockage and pollution of municipal pipelines.

Method used

A grease thickness sensor was designed, comprising a floating shell, a displacement sensor, and a chip transmission module. By monitoring the downward movement of the floating shell, the grease thickness is automatically calculated and the staff is promptly alerted to remove the grease.

Benefits of technology

It enables unmanned and intelligent monitoring of oil thickness, preventing oil layer overflow, reducing resource waste and processing costs, and protecting the ecological environment.

Claims

1. A fat thickness sensor characterized by, include, The floating body shell includes a first shell and a second shell sealed thereto; The battery module is housed within the first housing; A displacement sensor, installed inside the first housing, is used to monitor the downward displacement distance of the floating body housing; The chip transmission module receives signals from the displacement sensor and transmits them to an external platform. As the oil flows in, the floating body gradually sinks to the water-oil interface and reaches the threshold set by the displacement sensor. The displacement sensor then sends a signal to the chip transmission module, which in turn transmits the data to the platform.

2. The oil thickness sensor according to claim 1, wherein The first shell of the floating body is hemispherical with its opening facing upward, and the second shell is conical with its opening facing downward. The two openings are sealed together. When in contact with an oil-free liquid surface, the first shell is in contact with the liquid surface, and the second shell is vertically upward relative to the horizontal plane of the liquid surface.

3. The oil thickness sensor according to claim 1, wherein The battery module includes, but is not limited to, disposable dry batteries or rechargeable batteries.

4. The oil thickness sensor according to claim 1, wherein The overall density of the floating shell is adjusted to between 0.85 g / cm³ and 0.98 g / cm³ by filling it with internal counterweights or foam materials.

5. The oil thickness sensor according to claim 1, wherein The chip transmission module is an NB-IoT module.

6. The oil thickness sensor according to claim 1, wherein The chip transmission module wirelessly transmits data to an external platform, including but not limited to 4G, 5G, NB-IoT, or LoRa.
