Description

Technical Field

[0001] The invention relates to the field of ammonia water tanks, and in particular to an ammonia recovery measuring device which is convenient for measuring the liquid level of an ammonia water tank. Background Art

[0002] In the ammonia recovery system, accurate measurement of the liquid level in the ammonia tank is crucial to the stable operation and efficient recovery of the entire system. As a commonly used liquid level measurement tool, the communicating vessel is based on a simple and reliable communicating vessel principle and can intuitively reflect the liquid level height in the ammonia tank. It is widely used in the measurement of the liquid level in the ammonia tank.

[0003] During the ammonia recovery process, ammonia water often contains various impurities, such as particulate matter mixed in during the production process, precipitates produced by chemical reactions, etc. When the ammonia water flows or remains stationary in the communicating vessel, these impurities easily adhere to the inner wall of the communicating vessel and gradually form dirt over time.

[0004] Existing U-tubes usually do not have special cleaning mechanisms, and dirt will continue to accumulate, which not only affects the transparency of the U-tubes, making it difficult for operators to accurately observe the liquid level height, thereby reducing the measurement accuracy; on the other hand, the presence of dirt may also affect the flow state of ammonia water in the U-tubes, causing deviations in the liquid level display, further affecting the accuracy of the measurement results. Summary of the invention

[0005] The object of the present invention is to provide an ammonia recovery measuring device which is convenient for measuring the liquid level of an ammonia water tank, so as to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-4 As shown, the present invention provides a technical solution:

[0028] A measuring device for ammonia recovery that is convenient for measuring the liquid level of an ammonia water tank, comprising a communicating vessel 1, a return pipe 2 and a water inlet pipe 3 are respectively arranged at the upper and lower ends of the communicating vessel 1, a switching mechanism is arranged between the communicating vessel 1 and the return pipe 2 and the water inlet pipe 3, the switching mechanism comprises a reversing valve 1 7 and a reversing valve 2 8, the reversing valve 2 7 and the reversing valve 1 8 are respectively arranged at the upper and lower ends of the communicating vessel 1, the other two ends of the reversing valve 2 7 are respectively connected to the return pipe 2 and the elbow 1 9, the other two ends of the reversing valve 1 7 are respectively connected to the water inlet pipe 3 and the elbow 2 10, the switching mechanism also comprises a motor 11, the motor 11 is arranged outside the reversing valve 1 7 and the reversing valve 2 8, a valve core 12 is movably arranged inside the reversing valve 1 7 and the reversing valve 2 8, the motor 11 is fixedly connected to the valve core 12, the conveying groove of the valve core 12 is a T-shaped structure, and a scale 22 is vertically arranged on the outer wall of the communicating vessel 1;

[0029] In this embodiment, the communicating vessel 1 is connected to the ammonia tank so that the liquid level in the communicating vessel 1 is consistent with the liquid level in the ammonia tank, so that the liquid level in the ammonia tank can be indirectly measured through the communicating vessel 1. In the initial state, the connection state of the pipeline is controlled by the reversing valve 1 7 and the reversing valve 2 8 in the switching mechanism. Specifically, the motor 11 drives the valve core 12 to rotate. Since the conveying groove of the valve core 12 is a T-shaped structure, switching between different pipelines can be achieved. When the liquid level is measured, the reversing valve 1 7 and the reversing valve 2 8 adjust the passage so that the water inlet pipe 3 is connected to the communicating vessel 1, and the return pipe 2 is also connected to the communicating vessel 1, so that the ammonia in the ammonia tank can enter the communicating vessel 1. As the ammonia enters the communicating vessel 1, the liquid level in the communicating vessel 1 gradually rises, and the liquid level in the transparent inner tube 6 also rises accordingly. By observing the scale 22 corresponding to the liquid level in the transparent inner tube 6, the liquid level height in the ammonia tank can be read.

[0030] like Figure 2 and Figure 4 As shown, transparent clamps 4 are provided at the upper and lower ends of the middle part of the communicating vessel 1, a mounting frame 5 is provided between the outer sides of the transparent clamp 4, a circulation mechanism is provided between the mounting frame 5 and the communicating vessel 1, the circulation mechanism includes a circulation pump 13, the circulation pump 13 is provided on the right side of the mounting frame 5, the elbow 2 10 is connected with one end of the circulation pump 13 through an output pipe 14, a transparent inner tube 6 is provided at the inner wall of the middle part of the communicating vessel 1, a cleaning mechanism is provided between the transparent inner tube 6 and the communicating vessel 1, the cleaning mechanism includes a floating plate 18, the floating plate 18 is movably sleeved inside the transparent inner tube 6, a baffle 19 is provided at the middle of both ends of the communicating vessel 1, and notches 20 connected with the transparent inner tube 6 are provided on both sides of the communicating vessel 1 close to the baffle 19, and overflow ports 21 are provided at the upper and lower ends of the transparent inner tube 6, and the inner diameter of the overflow port 21 is larger than the inner diameter of the transparent inner tube 6;

[0031] In this embodiment, when the liquid level drops, the floating plate 18 will scrape off the impurities that may be attached to the inner wall of the transparent inner tube 6 during the process of descending, so as to clean the inner wall of the transparent inner tube 6. The blocking rods 19 provided in the middle of both ends of the communicating vessel 1 are used to limit the movement range of the floating plate 18 to prevent it from escaping from the transparent inner tube 6. At the same time, the notches 20 connected to the transparent inner tube 6 are provided on both sides of the communicating vessel 1 close to the blocking rods 19, so that the scraped impurities can be discharged from the transparent inner tube 6 through the notches 20.

[0032] like Figure 3 As shown, a filtering mechanism is provided between the elbow 9 and the other end of the circulation pump 13, and the filtering mechanism includes a connecting pipe 15 and an input pipe 16. The end of the elbow 9 away from the reversing valve 8 is connected to the input pipe 16, and the end of the circulation pump 13 away from the output pipe 14 is connected to the connecting pipe 15. A filter 17 is detachably provided between the connecting pipe 15 and the input pipe 16, and a filter element is provided inside the filter 17.

[0033] In this embodiment, in the filtering mechanism, the ammonia water is filtered through the filter valve core 12 inside the filter 17 to remove impurities in the ammonia water. The filtered ammonia water enters the circulation pump 13 through the connecting pipe 15, and then flows back to the communicating vessel 1 through the output pipe 14 and the elbow 10, thereby realizing the circulation filtration of the ammonia water, ensuring the cleanliness of the ammonia water in the measuring device, and avoiding impurities from affecting the measurement accuracy.

[0034] Working principle: The communicating vessel 1 is connected to the ammonia tank so that the liquid level in the communicating vessel 1 is consistent with the liquid level in the ammonia tank, so that the liquid level in the ammonia tank can be indirectly measured through the communicating vessel 1. In the initial state, the connection state of the pipeline is controlled by the reversing valve 1 7 and the reversing valve 2 8 in the switching mechanism. Specifically, the motor 11 drives the valve core 12 to rotate. Since the conveying groove of the valve core 12 is a T-shaped structure, switching between different pipelines can be achieved. When the liquid level is measured, the reversing valve 1 7 and the reversing valve 2 8 adjust the passage so that the water inlet pipe 3 is connected to the communicating vessel 1, and the return pipe 2 is also connected to the communicating vessel 1, so that the ammonia in the ammonia tank can enter the communicating vessel 1. As the ammonia enters the communicating vessel 1, the liquid level in the communicating vessel 1 gradually rises, and the liquid level in the transparent inner tube 6 also rises accordingly. By observing the scale 22 corresponding to the liquid level in the transparent inner tube 6, the liquid level height in the ammonia tank can be read. During cleaning, the circulation mechanism starts to work, and the circulation pump 13, the reversing valve 1 7, and the reversing valve 2 8 are started at the same time. The reversing valve 1 7 and the reversing valve 2 8 connect the communicating vessel 1 with the stop rod 19 and the elbow 2 10. The circulation pump 13 is connected to the input pipe 16 through the elbow 1 9 to extract the ammonia water in the communicating vessel 1 and flow to the filtering mechanism. In the filtering mechanism, the ammonia water is filtered through the filter element valve core 12 inside the filter 17 to remove impurities in the ammonia water. The filtered ammonia water enters the circulation pump 13 through the connecting pipe 15, and then flows back to the communicating vessel 1 through the output pipe 14 and the elbow 2 10 to realize the circulation filtration of the ammonia water, ensure the cleanliness of the ammonia water in the measuring device, and avoid the influence of impurities on the measurement accuracy. A floating plate 18 is arranged inside the transparent inner tube 6. As the liquid level rises and falls, the floating plate 18 floats up and down in the transparent inner tube 6. When the liquid level drops, the floating plate 18 will scrape off the impurities that may be attached to the inner wall of the transparent inner tube 6 during the descending process, so as to clean the inner wall of the transparent inner tube 6. The blocking rods 19 arranged in the middle of both ends of the communicating vessel 1 are used to limit the movement range of the floating plate 18 to prevent it from escaping from the transparent inner tube 6. At the same time, the notches 20 connected to the transparent inner tube 6 are arranged on both sides of the communicating vessel 1 close to the blocking rods 19, so that the scraped impurities can be discharged from the transparent inner tube 6 through the notches 20.
