Description

Technical Field

[0001] This utility model mainly relates to the field of brewing equipment technology, and in particular to a leak detection device for a brewing wastewater treatment reactor. Background Technology

[0002] Brewing wastewater is a typical high-concentration organic wastewater containing sugars, alcohols, organic acids, etc. Commonly used brewing wastewater treatment methods include physical, chemical, and biological methods. Biological treatment methods usually involve a series of reactors, including upflow anaerobic sludge blanket reactors (UASB), membrane bioreactors (MBR), and anaerobic sequential reactors (ASBR). Leakage is a common problem when these reactors are used to treat wastewater.

[0003] Current research on leak prevention in wastewater treatment reactors focuses on the development and application of leak detection technologies, such as fiber optic leak monitoring systems and ultrasonic leak detectors. However, existing technologies have certain limitations: (1) Functional limitations: mainstream equipment can only achieve passive detection of leak signals (such as pipeline damage location), lacks active control mechanisms, and cannot link actuators (such as valves and pumps) to automatically shut down the leak source, resulting in a delayed risk response; (2) Insufficient economic efficiency: high-precision leak detection equipment (such as distributed fiber optic sensing systems) relies on imported hardware and complex algorithms, with a single set costing hundreds of thousands of yuan, which is difficult to adapt to the low-cost R&D needs of laboratory pilot or pilot-scale stages, thus restricting the efficiency of technology verification and promotion. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a leak detection device for a brewing wastewater treatment reactor, with the aim of reducing the leak detection cost of the brewing wastewater treatment reactor and improving the leak detection effect.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A leak detection device for a brewing wastewater treatment reactor includes a liquid storage tank, a liquid level sensor, a first relay, a second relay, a third relay, a connector, and an alarm.

[0007] The liquid storage tank is located at the bottom of the reactor to collect any leakage from the reactor. The liquid level sensor is located at the bottom of the liquid storage tank and is electrically connected to a first relay. The first relay is connected to a second relay and a third relay. The second relay is connected to the reactor via a connector, and the third relay is connected to an alarm.

[0008] Furthermore, the second relay is connected to a peristaltic pump in the reactor via a connector.

[0009] Furthermore, the alarm connects to the terminal device via Bluetooth or WiFi.

[0010] Furthermore, the leak detection device also includes a signal recorder, which is used to record the number of times the reactor is powered on and off.

[0011] Furthermore, the input signals of the first, second, and third relays are passive contact signals or switching signals based on NPN transistors.

[0012] The beneficial effects of this utility model are:

[0013] The leak detection device for brewing wastewater treatment reactors described in this utility model places a liquid level sensor below the reactor. Once leaking liquid comes into contact with the liquid level sensor, the liquid level sensor outputs an electrical signal to a first relay. The first relay simultaneously transmits the electrical signal to a second relay and a third relay. The second relay disconnects the power supply to the reactor, thereby stopping the reactor from operating and promptly preventing further leakage. The third relay simultaneously triggers an alarm to provide an alarm reminder and transmits the alarm information to the terminal device to alert the user of the leak. The entire leak detection process is rapid and reduces the cost of leak detection for reactors compared to leak detection equipment that relies on imported hardware and complex algorithms.

[0017] The following describes an embodiment of the leak detection device for the brewing wastewater treatment reactor of this utility model with reference to the accompanying drawings. It should be understood that the embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model.

[0018] like Figure 1As shown, the leak detection device for the brewing wastewater treatment reactor of this utility model includes a liquid level sensor 1, a liquid storage tank 2, a first relay 3, a second relay 4, a third relay 5, a connector 6, and an alarm 8. The liquid storage tank 2 is located at the bottom of the brewing wastewater treatment reactor. The liquid level sensor 1 is located at the bottom of the liquid storage tank 2. The liquid level sensor 1 is connected to the first relay 3. The first relay 3 is connected to the second relay 4 and the third relay 5. The second relay 4 is connected to the reactor via the connector 6, and the third relay 5 is connected to the alarm 8. The liquid storage tank 2 is placed below the reactor, serving two purposes: firstly, as a signal source for the liquid level sensor 1, and secondly, to collect leaked liquid from the reactor, preventing the liquid from spreading to other areas.

[0019] The liquid level sensor 1 outputs a switch signal, operates on a DC 12 / 24V power supply, operates at a temperature of -20 to 80°C, and operates at a humidity of 20 to 95%. The liquid level sensor 1 is installed in the liquid storage tank 2, with a distance of less than 1.5 mm from the bottom surface of the liquid storage tank. The response rate of the liquid level sensor 1 is <50 ms.

[0020] The first relay 3, the second relay 4, and the third relay 5 are powered by DC, 9-36V, and are suitable for temperatures ranging from -25 to 80℃. The input signals for the first relay 3, the second relay 4, and the third relay 5 are passive contact signals or switching signals based on NPN transistors.

[0021] In this embodiment, connector 6 can be a plug-in connector or other connecting device.

[0022] Preferably, the leak detection device further includes a signal recorder 7, which is used to record the number of times the connector 6 is powered on and off, and the number of times the connector 6 is powered on and off is the number of times the reactor is powered on and off.

[0023] In this embodiment, the alarm 8 is connected to the terminal device via Bluetooth or WiFi, and while triggering a leak alarm, the leak alarm information is also transmitted to the end user via the terminal device.

[0024] The operating procedure of the leak detection device for the brewing wastewater treatment reactor described in this utility model is as follows: Figure 2As shown, the liquid storage tank 2 is first placed below the reactor, and the liquid level sensor 1 is placed in the liquid storage tank 2 according to the above-described positioning method. If the reactor is leak-free and operating normally, the first relay 3, the second relay 4, and the third relay 5 remain in the open state. If the reactor leaks, the liquid level sensor 1 detects liquid in the liquid storage tank 2, sends an electrical signal, the first relay 3 is turned on, and simultaneously sends electrical signals to the second relay 4 and the third relay 5, controlling the contacts of the second relay 4 and the third relay 5 to close. The second relay 4 turns on, controlling the connector 6 that supplies power to the peristaltic pump in the reactor to de-energize, the peristaltic pump stops operating, and the reactor is shut down. After the third relay 5 closes, the alarm 8 is activated to provide a leak alarm, and transmits the leak signal to the terminal device via Bluetooth or WiFi to remind the end user that the reactor has leaked.
