[0002] Ammonia escape detection devices are devices used to monitor the ammonia concentration in the environment, usually through ammonia sensors. These sensors can accurately detect the ammonia concentration in the air and transmit the data to the monitoring system or controller. The necessity of using ammonia escape detection devices mainly stems from the need to monitor and control ammonia. Ammonia is a toxic gas with a pungent odor. If the concentration is too high, it may cause serious harm to people's health.

[0003] Traditional ammonia escape detection devices usually include ammonia sensors and monitoring systems. First, install ammonia sensors in areas that need to be monitored, such as sewage treatment plants or chemical plants where ammonia leaks may occur. The sensor continuously monitors the ammonia concentration in the air. Once the ammonia concentration exceeds the preset safety threshold, the sensor will issue an alarm signal.

[0004] In the above-mentioned traditional ammonia escape detection device, since the detection sensor itself does not have the function of filtering the air, it is unable to directly filter the air, resulting in particulate matter in the air interfering with the detection, causing the sensor to misjudge or generate inaccurate data.

[0025] Specifically, firstly, the gas to be detected is introduced into the interior of the conveying part 2 through the external connecting pipe 1. In this process, the filter plate 11 and the dust collecting plate 10 filter the air efficiently to ensure that the gas entering the conveying part 2 is pure and free of impurities. As time goes by, a large amount of dust will gradually accumulate on the dust collecting plate 10 and the filter plate 11. By driving the fixed ring 7, the movable sleeve 6 can be driven to rotate on the outer wall of the screw 5, so that the movable sleeve 6 moves up and down on the outer wall of the screw 5, thereby realizing the overall movement of the cleaning mechanism. Next, the screw 5 is pulled to rotate at one end of the fixed half ring 3. When the screw 5 When it is no longer in contact with the movable half ring 4, the movable half ring 4 can be easily pulled to rotate at the other end of the fixed half ring 3 to expose the connecting plate 8. At this time, the connecting plate 8 is removed, and the dust collecting plate 10 and the filter plate 11 in the middle are conveniently cleaned thoroughly. After cleaning, just put the connecting plate 8 back in place, and then rotate the movable half ring 4 and the screw 5 in the opposite direction to re-fix the dust collecting plate 10 and the filter plate 11 between the external connecting pipe 1 and the conveying part 2. During the whole process, the sealing ring 9 always plays a sealing role to ensure that the gas will not leak, thereby ensuring the high efficiency of the filtering effect.

[0026] Reference Figure 1 and Figure 4 The outer wall of the conveying part 2 is fixedly connected with a detection part 12, a plurality of conveying holes 13 are opened inside the detection part 12, one end of the detection part 12 is fixedly connected with a discharge part 14, one end of the discharge part 14 is fixedly connected with a connecting flange 15, one side of the outer wall of the connecting flange 15 is fixedly connected to the outer wall of the external connecting pipe 1, the outer wall of the detection part 12 is fixedly connected with a detection channel 16, the detection channel 16 is arranged on one side of the outer wall of the conveying part 2, the inner wall of the detection channel 16 is fixedly connected with a detector 17, the detector 17 is arranged on the outer wall of the detection part 12, the detector 17 and the detection channel 16 are both arranged on one side of the outer wall of the discharge part 14, and a sealing ring 18 is arranged between the detection channel 16 and the detection part 12;

[0027] Specifically, when clean air is delivered to the interior of the detection section 12 through the delivery section 2, a portion of the air will naturally flow into the depths of the detection channel 16 along the cleverly designed delivery hole 13. During this process, the detector 17 of the MQ137 Ammonia Gas Sensor model located inside the detection channel 16 will immediately start its efficient detection mechanism to perform real-time ammonia content detection on the incoming air, which not only improves the accuracy of the detection, but also greatly improves the efficiency of the detection. Finally, through the precise docking of the connecting flange 15 at one end of the discharge section 14 with the connecting flange 15 at one end of the external connecting pipe 1, the ammonia escape detection device can be easily installed at the desired position to ensure the stable operation of the entire detection system.

[0028] Working principle: When the ammonia escape detection device is needed, the gas to be detected is first sent to the inside of the conveying part 2 through the external connecting pipe 1. In this process, the air is filtered through the filter plate 11 and the dust collecting plate 10. When a large amount of dust is gathered on the dust collecting plate 10 and the filter plate 11, the fixed ring 7 is driven to drive the movable sleeve 6 to rotate on the outer wall of the screw 5, so that the movable sleeve 6 moves up and down on the outer wall of the screw 5, and then the screw 5 is pulled to rotate at one end of the fixed semi-ring 3. When the screw 5 is no longer in contact with the movable semi-ring 4, the movable semi-ring 4 can be pulled to rotate at the other end of the fixed semi-ring 3 to expose the connecting plate 8, and then the connecting plate 8 can be removed, and the dust collecting plate 10 and the filter plate 11 in the middle are cleaned. After cleaning, the connecting plate 8 is put back, and then the movable semi-ring 4 and the screw 5 are rotated in the opposite direction to re-fix the dust collecting plate 10 and the filter plate 11 between the external connecting pipe 1 and the conveying part 2. This process is sealed by the sealing ring 9 to achieve the effect of high-efficiency filtration.

[0029] In addition, when clean air is delivered to the interior of the detection part 12 through the delivery part 2, a portion of the air will enter the interior of the detection channel 16 along the delivery hole 13. At this time, the detector 17 with the model number of MQ137 Ammonia GasSensor in the detection channel 16 performs real-time detection, thereby achieving the effect of automatic detection. Finally, the ammonia escape detection device is conveniently installed through the connecting flange 15 at one end of the discharge part 14 and the connecting flange 15 at one end of the external connecting pipe 1.
