Description

Technical Field

[0001] This utility model relates to the field of gasbag level monitoring technology for anaerobic reactors, and in particular to a gasbag level monitoring device and an anaerobic reactor capable of preventing water vapor from entering. Background Technology

[0002] An anaerobic reactor is a biological treatment device used to treat organic wastewater and solid waste. Through the action of anaerobic microorganisms, complex organic matter is broken down into simpler compounds, producing biogas (the main components of which are methane and carbon dioxide). It is widely used in wastewater treatment and other fields.

[0003] Anaerobic reactors typically consist of a tank and an air-filled roof mounted on top of the tank. The air-filled roof floats up and down within the tank as the biogas volume changes. Therefore, the biogas volume within the tank can be determined by monitoring the level of the air-filled roof. However, existing level monitoring methods can only intermittently monitor the highest and lowest points of the air-filled roof, and cannot monitor the real-time position of the roof and its corresponding biogas volume. This limitation makes it difficult to accurately grasp the dynamic changes of biogas within the tank during actual operation, thus affecting the rational planning and efficient management of biogas use. Utility Model Content

[0042] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] like Figures 1 to 5 As shown, one embodiment of this utility model provides a water vapor-proof airbag level monitoring device, which is applied to an anaerobic reactor to monitor the level of the airbag 12 in the anaerobic reactor. The anaerobic reactor includes a tank 11, an airbag 12, and a weight block 13; the airbag 12 is disposed inside the tank 11 and located at the top of the tank 11, and the airbag 12 can float up and down inside the tank 11; the weight block 13 is slidably disposed outside the tank 11 and is connected to the airbag 12 by a connector such as a steel wire rope. It should be noted that multiple weight blocks 13 are provided, and multiple weight blocks 13 are all connected to the airbag 12 and are arranged sequentially at intervals along the circumference of the airbag 12; the weight block 13 is used to pull the airbag 12 to move downward inside the tank 11. When biogas is generated inside the tank 11, the gas pressure inside the tank 11 increases, causing the airbag 12 to move upward against the pulling force of the weight block 13.

[0044] The aforementioned airbag level monitoring device capable of preventing water vapor accumulation includes a laser rangefinder 2, a mounting bracket 3, and a reflector 5. The mounting bracket 3 serves as the support structure for the laser rangefinder 2, with one end connected to the outer wall of the tank 11. The laser rangefinder 2 is mounted on the end of the mounting bracket 3 facing away from the outer wall of the tank 11. The reflector 5 is fixedly mounted on the load block 13 and is positioned opposite to the monitoring end of the laser rangefinder 2. The laser emitted from the monitoring end of the laser rangefinder 2 is reflected back to the monitoring end of the laser rangefinder 2 after hitting the reflector 5. In other words, the airbag level monitoring device based on the laser rangefinder 2 provided in this embodiment, through the cooperation of the laser rangefinder 2 and the reflector 5 mounted on the load block 13, obtains the level of the airbag 12 inside the tank 11 by monitoring the position of the load block 13.

[0045] Furthermore, the ambient temperature around the anaerobic reactor is relatively high, making it easy for condensation to form at the emitting end of the laser rangefinder 2. To address this issue, in this embodiment, the laser rangefinder 2 includes a sensor body 21 and a cover 22. The sensor body 21 includes a shell, a laser emitter, and a receiver, with the laser emitter and receiver housed within the shell. The sensor body 21 has an emitting end through which the laser emitter emits laser light. The cover 22 is connected to the sensor body 21 and positioned at the emitting end, specifically connected to the shell of the sensor body 21. Preferably, a sealing ring is provided between the cover 22 and the sensor body 21. Under the action of the sealing ring, external moisture will not enter the sensor, thus preventing condensation at the emitting end of the laser rangefinder 2 and improving the monitoring effect of the laser rangefinder 2.

[0046] The vapor-proof gasbag level monitoring device provided in this embodiment uses a laser rangefinder 2 in conjunction with a reflector 5 mounted on a weighted block 13 to obtain the level information of the gasbag 12 by monitoring the position of the weighted block 13. The laser rangefinder 2 has a high degree of automation and can monitor the amount of biogas in the tank 11 in real time, enabling rational planning and efficient management of biogas use. Simultaneously, a sealing ring is provided between the cover 22 and the sensor body 21. Under the action of the sealing ring, external moisture will not enter the sensor, thus preventing condensation at the emitting end of the laser rangefinder 2 and improving the monitoring effect of the laser rangefinder 2.

[0047] Optionally, the waterproof airbag level monitoring device provided in this embodiment of the invention can have a receiving groove 222 provided on the cover 22, or on the sensor body 21, or both the cover 22 and the sensor body 21 can have receiving grooves 222. The receiving groove 222 matches the sealing ring, and during assembly, the sealing ring is fitted into the receiving groove 222. By providing the receiving groove 222, the installation of the sealing ring can be facilitated, and the sealing effect can also be improved.

[0048] The water-resistant airbag level monitoring device provided in this embodiment of the invention includes a sensor body 21 with a first flange 211 at its transmitting end. Specifically, the first flange 211 is mounted on the housing of the sensor body 21. The cover 22 includes a second flange 221, with a transparent sealing plate on its inner edge. The first flange 211 and the second flange 221 are correspondingly arranged. During assembly, the first flange 211 and the second flange 221 are fastened together with bolts or screws to assemble the cover 22 with the sensor body 21. Preferably, both the cover 22 and the sensor body 21 are provided with receiving grooves 222. The receiving groove 222 on the cover 22 is located on the second flange 221, and the receiving groove 222 on the sensor body 21 is located on the first flange 211. By providing receiving grooves 222 on the first flange 211 and the second flange 221, the sealing ring is fixed, thereby improving the sealing effect.

[0049] Preferably, a sealant is also provided between the transparent sealing plate and the second flange 221 to improve the sealing effect.

[0050] Furthermore, in this embodiment, the first flange 211 is provided with a plurality of first screw holes, which are arranged sequentially at intervals along the circumference of the first flange 211; the second flange 221 is provided with a plurality of second screw holes, which are arranged sequentially at intervals along the circumference of the second flange 221; the first screw holes and the second screw holes are arranged in a one-to-one correspondence, and the first flange 211 and the second flange 221 are fastened to the corresponding first screw holes and second screw holes by screws. Preferably, the receiving groove 222 on the first flange 211 is located inside the annular hole formed by the first screw holes, and the receiving groove 222 on the second flange 221 is located inside the annular hole formed by the second screw holes.

[0051] Optionally, the waterproof airbag level monitoring device provided in this embodiment of the invention further includes a first mounting plate 6, which serves as a support structure for the reflector 5. The reflector 5 can be mounted on the first mounting plate 6 to improve its stability. A planar mounting surface is provided on the load-bearing block 13. One side of the first mounting plate 6 is fixedly connected to the mounting surface by a first fixing member such as a screw, rivet, or wire. The reflector 5 is fixed to the side of the first mounting plate 6 facing away from the mounting surface by a second fixing member such as a screw or rivet. Under the action of the first mounting plate 6, the reflector 5 has higher installation strength. Compared to directly mounting the reflector 5 onto the load-bearing block 13, it is unnecessary to create excessive structures on the reflector 5 to cooperate with the load-bearing block 13, thus avoiding interference with its cooperation with the laser rangefinder sensor 2.

[0052] As a preferred embodiment, the airbag level monitoring device capable of withstanding water vapor provided in this utility model embodiment also has an adhesive between the reflector 5 and the first mounting plate 6 to improve the connection strength between the reflector 5 and the first mounting plate 6 and improve reliability.

[0053] The airbag level monitoring device capable of withstanding water vapor provided in this embodiment of the utility model includes a vertically arranged guide tube 14 connected to the outer wall of the tank body 11, with a load-bearing block 13 slidably mounted on the guide tube 14. In an optional embodiment of the mounting bracket 3, the mounting bracket 3 includes a clamp and a second mounting plate; the second mounting plate can be fixed to the clamp by welding, the clamp is correspondingly arranged with the guide tube 14, the clamp is mounted on the guide tube 14 and located above the load-bearing block 13, and the laser range sensor 2 is fixed to the second mounting plate by screwing or riveting. By using the clamp and the second mounting plate to fix the laser range sensor 2 to the outside of the tank body 11, the structure is simple, the cost is low, and the reliability is high.

[0054] In another optional embodiment of the waterproof airbag level monitoring device provided in this utility model embodiment, the mounting bracket 3 includes a first frame 31, a second frame 32, and a third frame 33. The first frame 31 and the second frame 32 are preferably both plate-shaped structures, respectively disposed at both ends of the third frame 33, which is a rod-shaped structure. The first frame 31 is fixed to the outer wall of the tank 11 by screws or rivets, and the laser ranging sensor 2 is fixed to the second frame 32 by screws or rivets.

[0055] Optionally, the waterproof airbag level monitoring device provided in this embodiment of the present invention allows for relative rotation between the first frame 31 and the third frame 33, or relative rotation between the second frame 32 and the third frame 33, or relative rotation between both the first frame 31 and the third frame 33 and between the second frame 32 and the third frame 33. Through the above configuration, the angle of the laser rangefinder 2 can be adjusted so that the monitoring end of the laser rangefinder 2 is opposite to the reflector 5.

[0056] Preferably, in this embodiment, the first frame 31 and the third frame 33 can rotate relative to each other, and the second frame 32 and the third frame 33 can rotate relative to each other, so as to facilitate the adjustment of the angle of the laser rangefinder sensor 2, which has strong applicability.

[0058] Optionally, in this embodiment, a connecting frame 23 is attached to the sensor body 21. The connecting frame 23 is used to connect to the second frame 32, and the connecting frame 23 and the second frame 32 are fixedly connected by bolts. By setting the connecting frame 23 to connect to the second frame 32, there is no need to modify the structure of the sensor body 21, thereby reducing the cost of use.
