Description

Technical Field

[0001] This application relates to the technical field of ammonia water filling, and in particular to an ammonia water filling device. Background Technology

[0002] Ammonia water is an aqueous solution of gaseous ammonia. It is colorless, transparent, and has a pungent odor. Ammonia water is less dense than water, unstable, volatile, and easily decomposes when exposed to light and heat. Ammonia water itself is a non-flammable and non-explosive liquid. However, the ammonia gas separated from the water has a strong, pungent odor and is irritating and corrosive to the eyes, nose, and skin. It also poses a risk of combustion and explosion. As an important chemical raw material and environmentally friendly denitrification agent, the filling process of ammonia water requires ensuring stable flow rate, low bubble content, and high uniformity of liquid flow. Traditional filling devices often use straight pipe structures, which are prone to generating eddies due to the vertical impact of the liquid flow on the bottom of the tank. This can lead to bubble entrainment, violent liquid surface fluctuations, and even equipment vibration and structural fatigue.

[0003] Therefore, those skilled in the art have provided an ammonia water dispensing device to solve the problems mentioned in the background art. Utility Model Content

[0019] 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.

[0020] Example 1

[0021] like Figure 1 , 4 As shown in Figure 5, this application discloses an ammonia water filling device, including a filling component 2 installed at the filling port at the upper end of an ammonia water tank 1. The filling component 2 includes a flange 201, a pipe body 202 is installed at the center of the upper end of the flange 201, a spiral component is provided on the upper part of the pipe body 202, two symmetrically arranged mounting rods 215 are installed on the inner side wall of the pipe body 202 near the bottom end, a common fixing ring 220 is installed between the two mounting rods 215, an umbrella-shaped diffuser 221 is installed on the fixing ring 220, a second mounting groove 223 is opened at the bottom end of the umbrella-shaped diffuser 221 corresponding to the position of the mounting rod 215, a second nut 216 is installed on the outer side of the mounting rod 215 near the position of the pipe body 202, a fixing sleeve 217 is sleeved on the outer side of the mounting rod 215 near the position of the fixing ring 220, and the end of the fixing sleeve 217 near the fixing ring 220 is an inclined surface that fits the side wall of the umbrella-shaped diffuser 221.

[0022] The umbrella-shaped diffuser 221 is installed on the fixing ring 220 by aligning the mounting rod 215 with the second mounting groove 223. Rotating the second nut 216 causes the fixing sleeve 217 to press against the umbrella-shaped diffuser 221, thus installing the umbrella-shaped diffuser 221. When ammonia is added, the rotational kinetic energy is dispersed into radial flow. Combined with the shearing effect of the holes 222, the large-scale eddy is decomposed into micro-scale turbulence. The evenly distributed holes 222 on the conical surface decompose the liquid flow into multiple fine streams. The momentum cancels each other out, forming a uniform laminar flow. The design of the holes 222 can balance the flow rate and resistance.

[0023] like Figure 5 As shown, a limiting groove 219 is provided at the upper end of the mounting rod 215, and a limiting strip 218 is installed at the upper end of the inner side of the fixing sleeve 217. The limiting strip 218 is installed in the limiting groove 219. By setting the limiting strip 218 in conjunction with the limiting groove 219, the position of the fixing sleeve 217 can be limited.

[0024] like Figure 4 As shown, several uniformly distributed holes 222 are provided on the side wall of the umbrella-shaped diffuser 221. By opening holes 222 on the umbrella-shaped diffuser 221, the holes 222 have a shearing effect, which decomposes the large-scale eddy into micro-scale turbulence. The holes 222 can decompose the liquid flow into multiple thin streams, and the momentum cancels each other out to form a uniform laminar flow, which can balance the flow rate and resistance.

[0025] like Figure 2 , 3 As shown, the spiral assembly includes several inclined guide vanes 204. A mounting block 205 is installed at one end of each guide vane 204 near the tube body 202. Several annularly arranged first mounting grooves 203 are formed through the side wall of the tube body 202. A first mounting hole 207 is formed at the upper end of a first mounting ring 206, corresponding to the center of the first mounting groove 203. The guide vanes 204 are installed in the first mounting grooves 203 via the mounting block 205. Several annularly arranged threaded rods 208 are installed at the upper end of the first mounting ring 206. A first nut 209 is installed at the end of each threaded rod 208. A second mounting ring 210 is installed on the outer side of each threaded rod 208. A second mounting hole 212 is formed on the second mounting ring 210 corresponding to the position of the threaded rod 208. A plug rod 211 is installed at the bottom end of the mounting ring 210 corresponding to the position of the mounting block 205. The plug rod 211 passes through the mounting block 205 and is inserted into the first mounting hole 207. The threaded rod 208 passes through the second mounting hole 212. The first nut 209 is tightened to install the second mounting ring 210. The plug rod 211 passes through the mounting block 205 and is inserted into the first mounting hole 207. The guide vane 204 is installed. Ammonia water can change the flow direction of the liquid through multiple guide vanes 204 to form a rotating flow, reducing the generation of eddies. The rotating liquid flow converts axial kinetic energy into tangential kinetic energy, reducing the vertical impact force of the liquid flow on the bottom of the tank. Centrifugal force causes the less dense bubbles to gather towards the center and be released through the holes 222 of the subsequent umbrella diffuser 221, reducing the entrainment of gas in the liquid flow.

[0026] like Figure 3 As shown, a mating strip 214 is installed on the upper part of the first mounting ring 206 near the middle. A mating groove 213 is provided on the second mounting ring 210 at the position corresponding to the mating strip 214. By using the mating groove 213 in conjunction with the mating strip 214, the plug rod 211 can be aligned with the first mounting hole 207 and the threaded rod 208 can be aligned with the second mounting hole 212, which facilitates quick installation.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The implementation principle of the ammonia water injection device in this application embodiment is as follows:

[0030] After ammonia water enters the pipe body 202, its flow direction is changed by the annularly arranged guide vanes 204. The guide vanes 204 are connected to the mounting block 205 at an inclined angle. The mounting block 205 is fixed in the first mounting groove 203, forcing the liquid flow to rotate tangentially, converting axial kinetic energy into tangential kinetic energy, and reducing vertical impact force. The centrifugal force generated by the rotating liquid flow causes the less dense bubbles to gather towards the center of the pipe body, creating conditions for subsequent gas release. The rotating liquid flow enters the umbrella-shaped diffuser 221, where the evenly distributed holes 222 on its conical surface shear the liquid flow into multiple fine streams, ensuring the flow... While reducing resistance, the flow rate is increased, causing large-scale eddies to decompose into micro-scale turbulence. Multiple fine flow currents cancel each other out, ultimately forming a uniform laminar flow. This avoids surface fluctuations and secondary bubble generation. The guide vane 204 is precisely aligned with the first mounting hole 207 via the plug rod 211 and locked with the threaded rod 208 and the second mounting ring 210 to ensure structural stability. The umbrella-shaped diffuser 221 is pressed and fixed by the inclined surfaces of the mounting rod 215, the fixing ring 220, and the fixing sleeve 217. The limiting strip 218 and the limiting groove 219 prevent misalignment and enable quick assembly and disassembly.
