[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: It includes a housing 1, with support frames 2 connected to both sides of the housing 1, and a conveyor belt 3 connected between the support frames 2. Two mounting plates 4 are connected between the inner sides of the housing 1, and multiple cylinders 5 are connected to one side of each mounting plate 4. The output end of each cylinder 5 passes through the mounting plate 4 and is connected to a clamping plate 6. A photoelectric sensor (not shown) is connected to the inner side of the housing 1. When the conveyor belt 3 transports empty bottles to the filling station, the photoelectric sensor monitors the bottle mouth position in real time. When the bottle mouth reaches a preset position, the sensor triggers a signal to the control system, which then controls the conveyor belt to stop or... Upon startup, cylinder 5 pushes clamping plate 6 to hold the empty bottle. A partition 7 is connected between the inner sides of the shell 1. An anti-crystallization storage tank assembly is connected to the top of the partition 7. A cross 9 is connected to the top of the shell 1. Feed pipes 21 are connected to both sides of the anti-crystallization storage tank assembly. A connecting pipe 22 is connected between the feed pipes 21. An anti-crystallization filling assembly 23 is connected to one side of the connecting pipe 22. A constant temperature water tank assembly 24 is connected to one side of the anti-crystallization filling assembly 23. A filter assembly 20 is connected to one side of the shell 1. Observation windows are opened on both sides of the shell 1, and multiple sets of screw support legs 25 are connected to the bottom of the shell 1. Reference Figure 2As shown, the anti-crystallization storage tank assembly includes a storage tank 8 fixedly mounted on the top of the partition 7 and a servo motor 10 fixedly mounted on the top of the cross 9. The output end of the servo motor 10 extends into the storage tank 8 and is connected to a rotating shaft 11. A stirring blade 12 is connected to the surface of the rotating shaft 11. A nano-air ring 13 is connected to the bottom of the inner wall of the storage tank 8. One end of the nano-air ring 13 is connected to a nitrogen external pipe 14, and the other end of the nitrogen external pipe 14 extends through to the outside of the shell 1. An electric heating tape 18 is wrapped around the surface of the storage tank 8. One end of the electric heating tape 18 is connected to a temperature controller 19. A temperature sensor 17 is connected inside the storage tank 8. An exhaust pipe 15 is connected to the top of the storage tank 8. One end of the exhaust pipe 15 is connected to... A pressure relief valve 16 is installed. The electric heating tape 18 and servo motor 10 are started. The electric heating tape 18 keeps the raw materials in the storage tank 8 warm. The servo motor 10 drives the stirring blade 12 to rotate through the rotating shaft 11 to stir, ensuring uniform heating. At the same time, the nitrogen external pipe 14 is connected to an external nitrogen source. Multiple micro nitrogen bubbles are sprayed into the storage tank 8 through the nano gas ring 13. The bubbles rise and push the solution longitudinally, compensating for the radial flow defects of the stirring. The shear force generated by stirring breaks the bubbles, improves the gas-liquid contact efficiency, and inhibits crystallization. The nitrogen covers the liquid surface to form a gas seal layer (oxygen content ≤10ppm), which promotes the removal of volatile substances. The bubbles carry free ammonia (NH3) to the gas phase and are discharged to the washing tower for recovery through the exhaust pipe 15.

[0017] Reference Figure 3 As shown, the anti-crystallization filling assembly 23 includes a filling pipe 231 connected to the connecting pipe 22. A filling nozzle 232 is connected to the bottom end of the filling pipe 231. A flow valve 233 is connected between the filling pipe 231 and the filling nozzle 232 to control the filling flow rate. An outer casing pipe 234 is connected to the surface of the filling pipe 231. A circulation pipe 235 and an upper liquid pipe 236 are connected to one side of the outer casing pipe 234. A micro circulation pump 237 is connected to one side of the upper liquid pipe 236. The other ends of the circulation pipe 235 and the upper liquid pipe 236 are connected to the constant temperature water tank assembly 24. The micro circulation pump 237 draws out the warm water in the constant temperature water tank assembly 24 and discharges it into the outer casing pipe 234 through the upper liquid pipe 236, thereby keeping the filling pipe 231 warm and reducing the crystallization rate. The water that has dissipated heat flows back into the constant temperature water tank assembly 24 through the circulation pipe 235 for reheating and recycling.

[0018] Reference Figure 2As shown, the constant temperature water tank assembly 24 includes a water tank 241 fixedly installed on one side of the housing 1. A fixing frame 242 is connected to one side of the water tank 241. Multiple sets of electric heating elements 243 are connected to the inner side of the fixing frame 242. A second temperature sensor 244 is connected to one side of the inner wall of the water tank 241. The water in the water tank 241 is heated by the electric heating elements 243 to maintain it at a certain temperature. The temperature sensor 244 detects the internal water temperature, thereby ensuring the heat preservation effect of the anti-crystallization filling assembly 23.

[0019] Reference Figure 2 As shown, the filter assembly 20 includes a mounting bracket 201 fixedly mounted on one side of the housing 1. A sealing cover 203 is connected to the top of the mounting bracket 201. Multiple filter elements 202 are connected between the mounting bracket 201 and the sealing cover 203. Connecting pipes 204 are connected to one side of both the mounting bracket 201 and the sealing cover 203. A raw material external pipe 206 is connected to the bottom of the mounting bracket 201. A feed pipe 205 is connected to the top of the sealing cover 203. One end of the feed pipe 205 is connected to a cleaning pipe 207, and the other end of the cleaning pipe 207 is connected to an external water source. The intermediate filter element 202 includes a stainless steel mesh filter element, a PVDF ultrafiltration membrane, and a 1μm precision filter element. The raw material enters the filter assembly 20 through the external raw material pipe 206, and is filtered by each filter element 202 through the connection pipe 204. Finally, it is discharged into the storage tank 8 through the feed pipe 205. As shown in the attached figure, valves are connected to one end of the feed pipe 205 and the cleaning pipe 207. When cleaning is required, the valve at one end of the feed pipe 205 is closed, and an external water source is connected to the cleaning pipe 207 to backwash the filter elements 202 in the filter assembly 20.

[0020] The implementation principle of this application is as follows: When using this utility model, the raw material is first filtered through the filter assembly 20, and then injected into the storage tank 8 for storage. The servo motor 10 is started to drive the stirring blade 12 to stir, and at the same time the electric heating tape 18 is started to heat. Nitrogen gas is then introduced through the ammonia gas external pipe 14 and the nano gas ring 13 to ensure uniform heating effect and inhibit crystallization. The empty bottle is placed on the conveyor belt 3 and enters the equipment as it moves. After moving to the work station, the flow valve 233 is opened to start filling. The micro circulation pump 237 continuously draws out the warm water in the constant temperature water tank assembly 24 and discharges it into the outer casing pipe 234, thereby keeping the filling pipe 231 warm and thus preventing crystallization on the inner wall of the pipeline and the filling nozzle 232. The electric heating element 243 continuously heats the water in the water tank 241 to keep it at a constant temperature.
