Description

Technical Field

[0001] This invention relates to the field of ammonia water filling technology, and more specifically, to ammonia water filling and ammonia gas recycling mechanisms. Background Technology

[0002] Ammonia water is an aqueous solution of ammonia gas dissolved in water. It is a colorless and transparent liquid with a strong, pungent odor. During production and transportation, it is packaged according to requirements. In the prior art, for example, the literature with application number CN202310291654.3, the ammonia gas generated during the packaging process is recovered through a hollow outer tube, and the ammonia water is dissolved in demineralized water by spraying demineralized water. This method has the following drawbacks: 1. Although the existing technology can complete the recycling operation, there is a gap between the hollow outer tube and the tank after the hollow outer tube is inserted into the tank. Some ammonia gas will diffuse out through the gap. Furthermore, when the tank is filled with ammonia water, the hollow outer tube separates from the tank, and ammonia gas will still diffuse into the air. 2. When the demineralized water is mixed with ammonia gas by spraying, the actual space used for mixing the demineralized water and ammonia gas is only the space occupied by the falling demineralized water. Its space utilization rate is low and the mixing efficiency is low. Summary of the Invention

[0003] To address the above deficiencies, this invention provides an ammonia water dispensing and ammonia gas recycling mechanism, thereby solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The ammonia water dispensing and ammonia gas recycling system includes demineralized water, ammonia gas, ammonia water, tanks, barrels, circulating pumps, and supports, and also includes: The sealing plate, flexible sealing plate, slot and release assembly; a sealed cavity is formed between the sealing plate and the barrel body, the slot is located at the upper end of the barrel body, when the release assembly fixes the flexible sealing plate, the flexible sealing plate is in a bent state; when the release assembly releases the flexible sealing plate, the flexible sealing plate is in an unfolded state by its own elasticity and is stuck in the slot. The inlet and outlet pipes are used for ammonia injection and ammonia discharge, respectively. The inlet and outlet pipes should avoid the flexible sealing plate. The diffuser assembly and circulation pipe are installed on the circulation pipe, and the diffuser assembly is located at the bottom of the tank. The circulation pump drives the ammonia gas in the tank to circulate from bottom to top. During the circulation of the ammonia gas from bottom to top, it comes into contact with the demineralized water through the diffuser assembly.

[0005] Furthermore, a hydraulic rod is installed on the bracket, a sealing plate is installed on the telescopic end of the hydraulic rod, a sealing ring is installed on the lower surface of the sealing plate, the diameter of the sealing ring is the same as that of the opening of the barrel, and an expansion mask is installed on the outer ring of the sealing plate.

[0006] Furthermore, the release assembly includes a rigid tube installed on the lower surface of the sealing plate, with a suction cup installed at the lower end of the rigid tube to fix the flexible sealing plate, and a merging tube at the upper end of the rigid tube.

[0007] Furthermore, the lower ends of both the inlet and outlet pipes are semi-circular, and the inlet and outlet pipes pass through the sealing plate; the inlet pipe is connected to the external storage compartment.

[0008] Furthermore, the diffusion assembly includes an L-shaped tube installed at the lower end of the tank. The L-shaped tube is inserted into the tank. A hole one is opened at the lower end of the side wall of the L-shaped tube, a hole two is opened in the middle of the side wall of the L-shaped tube, and a hole three is opened at the upper end of the side wall of the L-shaped tube. A cone one is provided at the upper end of the hole one, a cone two is provided at the upper end of the hole two, and a cone three is provided at the upper end of the hole three.

[0009] Furthermore, the diffusion assembly also includes a baffle plate with a fourth hole, the diameter of which is smaller than that of the first, second and third holes.

[0010] Furthermore, the upper end of the circulation pipe is connected to the tank body, and the lower end of the circulation pipe is connected to the L-shaped pipe. The circulation pump is located at the upper end of the circulation pipe, and valve one is installed at the upper end of the circulation pipe. Both ends of valve one are connected to the circulation pipe, and valve one is also connected to the outlet pipe. Valve two is installed at the lower end of the circulation pipe.

[0011] Furthermore, a conveying mechanism is provided below the support frame, and the barrel is placed on the conveying mechanism.

[0012] The beneficial effects of this invention are: by using the sealing plate, the barrel is kept sealed from the outside world when ammonia is filled; ammonia leakage is prevented; by pre-setting a flexible sealing plate, the flexible sealing plate can quickly block the opening at the top of the barrel after the ammonia is filled, preventing ammonia from spreading into the air. The method of mixing demineralized water and ammonia in existing technologies has been changed. By setting up multiple cones, the ammonia can diffuse into the tank and fill the entire cavity of the tank, which greatly improves space utilization and mixing efficiency.

[0014] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] This application provides a mechanism for ammonia water dispensing and ammonia gas recycling. Please refer to [reference needed]. Figures 1-5 The system includes: 1. Demineralized water; 2. Ammonia gas; 3. Ammonia water; 4. Tank; 5. Barrel; 6. Circulation pump; and 7. Support frame. It also includes: The sealing plate 8, flexible sealing plate 9, slot 10, and release assembly are included. A sealed cavity is formed between the sealing plate 8 and the barrel body 5. The slot 10 is located at the upper end of the barrel body 5. When the release assembly fixes the flexible sealing plate 9, the flexible sealing plate 9 is in a bent state. When the release assembly releases the flexible sealing plate 9, the flexible sealing plate 9 is in an unfolded state due to its own elasticity and is stuck in the slot 10. Inlet pipe 11 and outlet pipe 12, inlet pipe 11 is used for the injection of ammonia water 3, outlet pipe 12 is used for the discharge of ammonia gas 2, inlet pipe 11 and outlet pipe 12 avoid the flexible sealing plate 9; The diffusion assembly and circulation pipe 13 are installed on the circulation pipe 13. The diffusion assembly is located at the bottom of the tank 4. The circulation pump 6 drives the ammonia gas 2 in the tank 4 to circulate from bottom to top. During the circulation of the ammonia gas 2 from bottom to top, it comes into contact with the demineralized water 1 through the diffusion assembly.

[0016] In practical applications, demineralized water 1 is located inside tank 4, and ammonia 2 is generated when ammonia water 3 is filled into barrel 5. After ammonia water 3 is prepared, it enters barrel 5 through inlet pipe 11. In actual use, the steps are as follows; Step 1; The flexible sealing plate 9 is bent upwards on both sides manually. At this time, the flexible sealing plate 9 has unfolding stress. The flexible sealing plate 9 can be fixed below the sealing plate 8 by the release component. Step Two; The hydraulic rod 21 is extended, causing the sealing plate 8, flexible sealing plate 9, inlet pipe 11, and outlet pipe 12 to move downwards until the sealing plate 8 seals the upper end of the barrel 5. At this time, a sealed cavity is formed between the sealing plate 8 and the barrel 5. The flexible sealing plate 9, with its folded sides, can overcome the restriction of the barrel 5 using its own flexibility until the flexible sealing plate 9 is located in the slot 10. At this time, the flexible sealing plate 9, with its folded sides, is stuck in the slot 10. Then, the ammonia water 3 is controlled to enter the barrel 5 through the inlet pipe 11. As the liquid level in the barrel 5 rises, the ammonia gas 2 that evaporates in the sealed cavity is discharged through the outlet pipe 12 and flows back into the tank 4. Step 3; After the ammonia water 3 is filled into the tank 4, the control release component releases the flexible sealing plate 9. At this time, the folded flexible sealing plate 9 unfolds using its own elasticity and is locked in the slot 10, sealing the top of the tank 5 to achieve a temporary sealing effect. The sealing cover is then manually installed for long-term sealing. Step four; Ammonia gas 2 in outlet pipe 12 enters tank 4 from below through circulation pipe 13. During the entry process, when ammonia gas 2 passes through diffusion component, it can be dispersed to form multiple small bubbles, so that ammonia gas 2 can fully contact demineralized water 1. Ammonia gas 2 and demineralized water 1 combine to form a semi-finished product of low-concentration ammonia water 3. Step 5; The circulation pump 6 is controlled to work, and the circulation pump 6 drives the ammonia gas 2 in the tank 4 to circulate from bottom to top; the combination time of ammonia gas 2 and demineralized water 1 is increased; the pressure in the tank 4 is increased, which can increase the solubility of demineralized water 1. After the demineralized water 1 and ammonia gas 2 have combined for a certain period of time, the valve 2 64 is opened to discharge low-concentration ammonia water 3.

[0017] Reference Figures 1 to 5 A hydraulic rod 21 is installed on the bracket 7, and a sealing plate 8 is installed on the telescopic end of the hydraulic rod 21. A sealing ring 22 is installed on the lower surface of the sealing plate 8. The diameter of the sealing ring 22 is the same as that of the opening of the barrel 5. An expansion mask 23 is installed on the outer ring of the sealing plate 8.

[0018] In practical applications, when the hydraulic rod 21 extends, it can drive the sealing plate 8 to move downward. The sealing ring 22 can increase the sealing between the sealing plate 8 and the barrel 5. With the setting of the expansion mask 23, when the sealing plate 8 and the barrel 5 are misaligned by a short distance, they can automatically align themselves.

[0019] Reference Figures 1 to 5 The release assembly includes a rigid tube 31 installed on the lower surface of the sealing plate 8, a suction cup 32 installed at the lower end of the rigid tube 31, the suction cup 32 fixing the flexible sealing plate 9, and a merging pipe 33 provided at the upper end of the rigid tube 31.

[0020] In practical applications, the rigid tube 31 and the confluence tube 33 can connect the vacuum pump and the suction cup 32. While the rigid tube 31 transmits air pressure, it keeps the suction cup 32 in a stable state. The flexible sealing plate 9 is manually moved to the position of the suction cup 32, and then the vacuum pump is controlled to work so that the suction cup 32 fixes the flexible sealing plate 9.

[0021] Reference Figures 1 to 5 The lower ends of both the inlet pipe 11 and the outlet pipe 12 are semi-circular, and the inlet pipe 11 and the outlet pipe 12 pass through the sealing plate 8; the inlet pipe 11 is connected to the external storage chamber.

[0022] In practical applications, the inlet pipe 11 and outlet pipe 12 are Y-shaped. The finished ammonia water 3 in the external storage chamber enters the barrel 5 through the inlet pipe 11; the inlet pipe 11 and outlet pipe 12 extend downward to form a sealing plate 8.

[0023] Reference Figures 1 to 5 The diffusion assembly includes an L-shaped tube 51 installed at the lower end of the tank 4. The L-shaped tube 51 is inserted into the tank 4. The lower end of the side wall of the L-shaped tube has a hole 52, the middle of the side wall of the L-shaped tube has a hole 53, and the upper end of the side wall of the L-shaped tube has a hole 54. The upper end of the hole 52 has a cone 55, the upper end of the hole 53 has a cone 56, and the upper end of the hole 54 has a cone 57.

[0024] In practical applications, after ammonia 2 passes through L-shaped pipe 51, it can be discharged through hole 1 52, hole 2 53, and hole 3 54. Cone 1 55 transports the bubbles of ammonia 2 to a position close to the side wall of tank 4, cone 2 56 transports the bubbles of ammonia 2 to a position at half the radius of tank 4, and cone 3 57 transports the bubbles of ammonia 2 to the center of tank 4. Through the above structure, ammonia 2 can fully contact demineralized water 1.

[0025] Reference Figures 1 to 5 The diffusion assembly also includes a baffle plate 61, on which a fourth hole 62 is formed, the diameter of which is smaller than that of the first hole 52, the second hole 53 and the third hole 54.

[0026] In practical applications, the baffle plate 61 and the four holes 62 can further reduce the size of the ammonia gas 2 bubbles and further increase the contact area between the ammonia gas 2 and the demineralized water 1.

[0027] Reference Figures 1 to 5 The upper end of the circulation pipe 13 is connected to the tank 4, and the lower end of the circulation pipe 13 is connected to the L-shaped pipe 51. The circulation pump 6 is located at the upper end of the circulation pipe 13. A valve 63 is provided at the upper end of the circulation pipe 13. Both ends of the valve 63 are connected to the circulation pipe 13, and the valve 63 is also connected to the outlet pipe 12. A valve 64 is installed at the lower end of the circulation pipe 13.

[0028] In practical applications, when filling ammonia water 3, valve 2 64 is closed, and valve 1 63 controls ammonia gas 2 to move downward through circulation pipe 13 until it is injected into tank 4; when filling ammonia water 3 stops, circulation pump 6 works to circulate and combine ammonia gas 2 in tank 4 with demineralized water 1.

[0029] Reference Figures 1 to 5 A conveying mechanism 81 is provided below the support 7, and the barrel 5 is placed on the conveying mechanism 81.

[0030] In practical applications, the conveying mechanism 81 can automatically move the barrel 5 under the sealing plate 8.
