An integrated device for preparing ammonia water by mixing liquid ammonia and water

Abstract

This utility model relates to the technical field of ammonia preparation equipment, and discloses an integrated device for preparing ammonia by mixing liquid ammonia with water, including a mixing chamber, wherein a fixing ring is fixedly sleeved inside the mixing chamber. This integrated device for preparing ammonia by mixing liquid ammonia with water uses a liquid ammonia delivery pipe with through holes to distribute liquid at the bottom of the mixing chamber, and rotates it in the opposite direction to the stirring blades. The liquid ammonia jet ejected from the delivery pipe forms a counter-current with the mainstream field generated by the stirring blades, generating a strong shearing force that cuts the liquid ammonia jet into fine droplets, increasing the contact area between liquid ammonia and water, thereby significantly improving the mixing efficiency. Simultaneously, the position of the through holes changes continuously as the delivery pipe rotates, ensuring that the liquid ammonia is evenly distributed in the mixing chamber. Combined with the stirring of the stirring blades, this ensures uniform diffusion of liquid ammonia throughout the entire space, achieving a high degree of uniformity in ammonia mixing and effectively solving the problem of localized excessively high or low concentrations caused by uneven liquid ammonia distribution in traditional equipment.

Description

Technical Field

[0001] This utility model relates to the technical field of ammonia water preparation equipment, and more specifically, to an integrated device for preparing ammonia water by mixing liquid ammonia with water. Background Technology

[0002] In the chemical production field, ammonia water is an important chemical raw material widely used in fertilizer manufacturing, pharmaceuticals, wastewater treatment, and other industries. Currently, the common method for preparing ammonia water by mixing liquid ammonia with water is to introduce liquid ammonia and water into a specific mixing device in a certain proportion for stirring and mixing. Most traditional ammonia water preparation equipment currently uses a single feed pipe to transport liquid ammonia to the mixing chamber, with the liquid ammonia directly entering the water from the pipe outlet. This method results in a slow diffusion rate of liquid ammonia in the water, making it difficult for liquid ammonia and water to achieve sufficient contact in a short time, leading to low mixing efficiency. Furthermore, due to uneven distribution of liquid ammonia, localized high concentrations and low concentrations in other areas can easily occur, failing to guarantee the uniformity of ammonia water mixing and affecting the quality of the ammonia water product. In addition, in existing ammonia water preparation equipment, the stirring device usually only has a single stirring function, with the stirring component and the liquid ammonia conveying component relatively fixed, lacking effective synergy. During the stirring process, the diffusion path of liquid ammonia in the water is relatively simple, failing to fully utilize the stirring force to promote the mixing of liquid ammonia and water, further limiting the improvement of mixing efficiency and quality. Therefore, improvements are needed. Utility Model Content

A toothed ring is fixedly installed at the bottom of the rotating ring. The outer surface of the toothed ring meshes with the outer surface of the drive gear.

[0008] As a preferred embodiment of this utility model, a protective shell is fixedly installed at the bottom of the mixing chamber. The outer surface of the protective shell is movably connected to the inside of the rotating ring, and the inside of the top of the protective shell is movably connected to the outer surface of the vertical shaft.

There are two infusion tubes, and a support plate is fixedly sleeved on the outer surface of each of the two infusion tubes. The top end of the support plate is fixedly connected to the bottom end of the mixing chamber. A second liquid pump and a third liquid pump are respectively provided on the two infusion tubes.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This integrated device for preparing ammonia water by mixing liquid ammonia with water uses a liquid ammonia delivery pipe with through holes to distribute liquid at the bottom of the mixing chamber and rotates in the opposite direction to the stirring blades. The liquid ammonia jet ejected from the delivery pipe forms a counter-current with the mainstream field generated by the stirring blades, generating a strong shearing force that cuts the liquid ammonia jet into fine droplets, increasing the contact area between liquid ammonia and water, thereby significantly improving the mixing efficiency. At the same time, the position of the through holes changes continuously as the delivery pipe rotates, ensuring that the liquid ammonia is evenly distributed in the mixing chamber. Combined with the stirring of the stirring blades, this ensures that the liquid ammonia diffuses evenly throughout the entire space, achieving a high degree of uniformity in ammonia water mixing and effectively solving the problem of local concentrations that are too high or too low due to uneven distribution of liquid ammonia in traditional equipment.

[0018] 2. This integrated device for preparing ammonia water by mixing liquid ammonia with water releases a large amount of heat during the mixing process, which may cause a sharp increase in pressure within the mixing chamber, posing a safety hazard. This device uses a pressure sensor to monitor the internal pressure of the mixing chamber in real time. Once the pressure exceeds a preset safety threshold, the system immediately triggers an alarm to attract nearby operators to check the situation and perform pressure relief operations, preventing explosions, leaks, and other safety accidents caused by excessive pressure. This provides reliable safety assurance for production personnel and equipment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 9 As shown, this utility model provides an integrated device for preparing ammonia water by mixing liquid ammonia with water, comprising:

[0031] Mixing chamber 1, with a fixing ring 2 fixedly sleeved inside the mixing chamber 1;

[0032] A mixing mechanism is located at the bottom of the mixing chamber 1;

[0033] The mixing mechanism includes a motor 3, the top of which is fixedly connected to the bottom of the mixing chamber 1. A rotating shaft 4 is fixedly sleeved at the output end of the motor 3. A drive gear 5 is fixedly sleeved on the outer surface of the rotating shaft 4. A driven gear 6 is meshed with the surface of the drive gear 5. A vertical shaft 7 is fixedly sleeved inside the driven gear 6. The top of the vertical shaft 7 is meshed with the inside of the top of the mixing chamber 1. A stirring blade 8 is fixedly sleeved on the outer surface of the vertical shaft 7. A connecting hole 9 is opened at the bottom of the outer surface of the vertical shaft 7. A connecting ring 10 is fixedly sleeved at the bottom of the outer surface of the vertical shaft 7. A conveying pipe 11 is fixedly sleeved inside the connecting ring 10. The inside of the conveying pipe 11 is connected to the inside of the vertical shaft 7 through the connecting hole 9. A through hole 12 is opened on the outer surface of the conveying pipe 11. A rotating ring 13 is fixedly installed at the end of the conveying pipe 11 away from the connecting ring 10. A toothed ring 14 is fixedly installed at the bottom of the rotating ring 13. The outer surface of the toothed ring 14 is meshed with the outer surface of the drive gear 5.

[0034] Because the interior of the vertical shaft 7 is connected to the interior of the conveying pipe 11 through the connecting hole 9, the liquid ammonia inside the vertical shaft 7 can enter the interior of the conveying pipe 11 through the connecting hole 9. Then, this liquid ammonia will flow into the interior of the mixing chamber 1 through the through hole 12. When the motor 3 runs, the rotating shaft 4 will drive the drive gear 5 to rotate. At this time, the drive gear 5 will simultaneously drive the driven gear 6 and the gear ring 14 to rotate. During this process, the rotation direction of the driven gear 6 is opposite to the rotation direction of the gear ring 14. When the driven gear 6 rotates, it will drive the stirring blade 8 to rotate through the vertical shaft 7. The stirring blade 8 will stir and mix the liquid ammonia and water inside the mixing chamber 1. At the same time, the toothed ring 14 will drive the rotating ring 13 to rotate along the inside of the fixed ring 2. Then, the rotating ring 13 will drive the connecting ring 10 to rotate around the vertical axis 7 through the conveying pipe 11. When the conveying pipe 11 rotates, it will make the liquid ammonia evenly distributed inside the mixing chamber 1. Since the rotation direction of the conveying pipe 11 is opposite to the rotation direction of the stirring blade 8, the liquid ammonia will form a counter-current with the stirring flow field of the stirring blade 8, generating a strong shear force, thereby greatly improving the mixing efficiency.

[0035] The bottom of the mixing chamber 1 is fixedly installed with a protective shell 15. The outer surface of the protective shell 15 is movably connected with the inside of the rotating ring 13. The inside of the top of the protective shell 15 is movably connected with the outer surface of the vertical shaft 7. The gear ring 14, the drive gear 5 and the driven gear 6 are all located inside the protective shell 15.

[0036] Due to the design of the protective shell 15, it can provide good protection for the driven gear 6, the drive gear 5 and the gear ring 14.

[0037] The upper surface of the vertical shaft 7 is movably sleeved with an inlet pipe 17, and the upper surface of the inlet pipe 17 is fixedly sleeved with a vertical plate 16. The bottom end of the vertical plate 16 is fixedly connected to the top end of the mixing chamber 1. A first liquid pump 18 is provided on the inlet pipe 17, and the first liquid pump 18 is fixedly connected to the upper surface of the vertical plate 16.

[0038] Due to the design of the vertical plate 16, it will provide good support for the liquid inlet pipe 17 and the first liquid pump 18. When the first liquid pump 18 is running, the liquid ammonia inside the liquid inlet pipe 17 will flow into the vertical shaft 7.

[0039] The mixing chamber 1 has two infusion tubes 19 fixedly sleeved inside the bottom end. The outer surfaces of the two infusion tubes 19 are fixedly sleeved with support plates 20. The top of the support plates 20 is fixedly connected to the bottom end of the mixing chamber 1. The two infusion tubes 19 are respectively equipped with a second liquid pump 21 and a third liquid pump 31.

[0040] When the second liquid pump 21 is running, the water inside the infusion pipe 19 will flow into the mixing chamber 1. After the ammonia water is prepared, the operator starts the third liquid pump 31. At this time, the ammonia water inside the mixing chamber 1 will flow out of the mixing chamber 1 through the infusion pipe 19. Due to the design of the support plate 20, it will provide good support for the infusion pipe 19, the second liquid pump 21 and the third liquid pump 31.

[0041] Among them, a fixing plate 22 is fixedly sleeved on the outer surface of the mixing chamber 1, and a base frame 23 is fixedly installed at the bottom end of the fixing plate 22.

[0042] Due to the design of the fixing plate 22 and the base frame 23, the mixing chamber 1 will be well supported, so that the mixing chamber 1 can be placed stably on the ground.

[0043] A pressure sensor 24 is fixedly installed at the top of the mixing chamber 1, and a display 25 and a buzzer 26 are fixedly installed at the top of the mixing chamber 1. A controller is installed inside the display 25.

[0044] Due to the design of the pressure sensor 24, the pressure inside the pressure sensor 24 can be monitored in real time and the detection data can be sent to the controller built into the display 25. Due to the design of the display 25, the monitoring data can be displayed so that the operator can know the pressure inside the mixing chamber 1. When the data sent by the pressure sensor 24 to the controller built into the display 25 exceeds the pressure threshold, the controller will send a signal to the buzzer 26 to activate it. At this time, the buzzer 26 will sound an alarm to attract nearby operators to check the situation.

[0045] Among them, a threaded tube 27 is fixedly sleeved inside the top of the mixing chamber 1, and a threaded sleeve 28 is threadedly sleeved on the outer surface of the threaded tube 27. A vertical groove 29 is opened on the threaded sleeve 28.

[0046] Since the threaded sleeve 28 is threadedly connected to the threaded tube 27, when the threaded sleeve 28 rotates, it will move upward along the outer surface of the threaded tube 27. Subsequently, the interior of the mixing chamber 1 will be connected to the outside of the mixing chamber 1 through the threaded tube 27 and the vertical groove 29, so that the pressure inside the mixing chamber 1 can be released.

[0047] Among them, the outer surface of the threaded sleeve 28 is fixedly fitted with a screwing block 30, and the screwing block 30 adopts a wave-shaped design.

[0048] The design of the screwing block 30 makes it easier for operators to screw the threaded sleeve 28.

[0049] The mixing mechanism and protective shell 15 are made of stainless steel, while the inlet pipe 17 and the delivery pipe 19 are made of high-density polyethylene.

[0050] Since the mixing mechanism and the protective shell 15 are both made of stainless steel, they are endowed with high pressure resistance, low temperature resistance and strong corrosion resistance. Since the inlet pipe 17 and the delivery pipe 19 are both made of high-density polyethylene, they are endowed with high low temperature resistance, strong impact resistance and excellent corrosion resistance.

[0051] Working principle and usage process of this utility model:

[0052] When the operator needs to prepare ammonia, they first start the second liquid pump 21. Water from the infusion pipe 19 flows into the mixing chamber 1. Once the amount of water added to the mixing chamber 1 reaches the mixing ratio, the operator shuts off the second liquid pump 21 and simultaneously starts the motor 3. The rotating shaft 4 then drives the drive gear 5 to rotate. Since the outer surface of the drive gear 5 meshes with the driven gear 6 and the gear ring 14, the rotation of the drive gear 5 simultaneously drives the driven gear 6 and the gear ring 14 to rotate. During this process, the rotation of the driven gear 6 and the gear ring 14... In the opposite direction, when the driven gear 6 rotates, it will drive several sets of stirring blades 8 to rotate via the vertical shaft 7. Due to the design of the stirring blades 8, when the stirring blades 8 rotate, they will stir the water inside the mixing chamber 1. At the same time, the gear ring 14 will drive the rotating ring 13 to rotate along the inside of the fixed ring 2. At this time, the rotating ring 13 will simultaneously drive the six delivery pipes 11 to rotate. Then, the six delivery pipes 11 will drive the connecting ring 10 to rotate around the vertical shaft 7. During this process, the overall rotation direction of the delivery pipes 11 is opposite to the rotation direction of the stirring blades 8. Then, the operator will use the first liquid pump 18. The liquid ammonia inside the inlet pipe 17 will flow into the vertical shaft 7, and then flow through the vertical shaft 7 into the delivery pipe 11. Subsequently, the liquid ammonia will flow through several through holes 12 into the mixing chamber 1. Due to the design of the delivery pipe 11 and the through holes 12, the liquid ammonia can be evenly released into the water. Since the density of liquid ammonia is less than that of water, the liquid ammonia will flow upwards upon entering the water, allowing the liquid ammonia and water to achieve sufficient contact in a short time. Furthermore, because the stirring blades 8 and the delivery pipe 11 rotate in opposite directions, the liquid ammonia flowing from inside the delivery pipe 11... The liquid ammonia ejected can form a counter-current impact with the stirring blade 8. This impact can generate strong shear force in the mixing chamber, cutting the liquid ammonia jet into finer droplets, increasing the contact area between liquid ammonia and water, accelerating the mass transfer process, and achieving efficient dispersion of materials through shearing. Furthermore, due to the design of the drive gear 5, the driven gear 6 rotates faster than the gear ring 14, which in turn makes the stirring blade 8 rotate faster than the conveying pipe 11. The speed difference between the two enhances the mixing effect of liquid ammonia and water, thereby achieving the function of efficient and uniform mixing of ammonia liquid and water.

[0053] During the ammonia preparation process, the mixing of liquid ammonia and water is accompanied by a heat of solution, which may cause pressure fluctuations within the chamber. This can lead to excessively high pressure inside mixing chamber 1. Due to the design of pressure sensor 24, the pressure inside mixing chamber 1 can be monitored in real time, and the detection data is sent to the controller built into display 25 in real time. The controller then displays this data on display 25 so that the operator can know the pressure inside mixing chamber 1 in real time. When pressure sensor 24 detects that the pressure inside mixing chamber 1 is too high, it sends a signal to the controller built into display 25. At this time, display 25 controls buzzer 26 to operate, causing buzzer 26 to emit a sharp and sustained sound. The alarm continues to attract nearby operators to check the situation. When it is necessary to depressurize the inside of the mixing chamber 1, the operator will turn the screw block 30. The screw block 30 will drive the threaded sleeve 28 to rotate along the outer surface of the threaded tube 27. Since the inside of the threaded sleeve 28 is threadedly connected to the outer surface of the threaded tube 27, when the threaded sleeve 28 rotates, it will move upward along the outer surface of the threaded tube 27. Then the inside of the mixing chamber 1 will be connected to the outside through the inside of the threaded tube 27 and the vertical groove 29, so that the pressure inside the mixing chamber 1 can be released. After the ammonia water is mixed and prepared, the operator will start the third liquid pump 31. At this time, the ammonia water inside the mixing chamber 1 will flow out of the mixing chamber 1 through the infusion pipe 19.
