Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, and in particular to a dispensing device for preventing crystallization of automotive urea solution. Background Technology

[0002] Automotive urea is an essential product for heavy-duty diesel vehicles to meet the China IV emission standard. Automotive urea refers to a urea aqueous solution with a urea concentration of 32.5% and ultrapure water as the solvent. The raw materials are special raw materials for automotive urea and ultrapure water. The automotive urea preparation device mixes ordinary urea with pure water to reach a certain proportion, thereby reducing vehicle emission pollution.

[0003] During the preparation of anti-crystallization automotive urea solution, it is necessary to dispense the urea solution into different volumetric flasks. Some existing dispensing devices exhibit dripping from the output tube at the end of filling, which may lead to contamination of the device. Therefore, an anti-crystallization automotive urea solution dispensing device is proposed. Utility Model Content

[0012] Preferably, a support leg is fixedly installed on the bottom surface of the workbench, and an anti-slip pad is fixedly installed on the bottom surface of the support leg.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-crystallization vehicle urea solution dispensing device, through the setting of the lifting mechanism, drives the connecting block to move, causing the infusion cylinder to move downward, so that the infusion tube is inserted into the inside of the sealed volumetric flask. When the valve is opened, the urea solution in the storage tank enters into the infusion cylinder through the connecting tube.

[0018] 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.

[0019] Example: Refer to Figure 1-3This utility model provides a technical solution: a device for dispensing automotive urea solution to prevent crystallization. It includes a workbench 1, with a rotary motor 2 fixedly installed inside. A turntable 3 is fixedly installed at the output end of the rotary motor 2. A placement groove 4 is fixedly installed on the top surface of the turntable 3. Fixing bolts 5 are threaded into the placement groove 4. There are two sets of placement grooves 4, and one end of each fixing bolt 5 contacts the surface of a sealed volumetric flask 6. The fixing bolts 5 facilitate the fixing of the sealed volumetric flask 6 within the placement groove 4. The sealed volumetric flask 6 is placed on the top surface of the placement groove 4. A vertical plate 7 is fixedly installed on the top surface of the workbench 1. A top plate 8 is fixedly installed on the top surface of the vertical plate 7. A storage tank 9 is fixedly installed on the top surface of the top plate 8. An inlet pipe 10 is installed, and a sealing cap is provided on the top surface of the inlet pipe 10. The inlet pipe 10 facilitates the addition of solution to the storage tank 9. A connecting pipe 11 is fixedly installed on one side of the storage tank 9. A valve 12 is installed inside the connecting pipe 11, and one end of the connecting pipe 11 is fixedly connected to the infusion cylinder 17. The connecting pipe 11 facilitates the flow of solution from the storage tank 9 into the infusion cylinder 17. A lifting mechanism is installed inside the upright plate 7. The lifting mechanism includes a lifting motor 13 fixedly installed inside the upright plate 7. A lead screw 14 is fixedly installed at the output end of the lifting motor 13, and a threaded block 15 is installed on the threaded surface of the lead screw 14. The lifting mechanism allows the infusion tube 18 to be inserted into the sealed volumetric flask 6, preventing... The dripping mechanism has a connecting block 16 fixedly installed at its output end. An infusion cylinder 17 is fixedly installed on one side of the connecting block 16. An infusion tube 18 is fixedly installed on the bottom surface of the infusion cylinder 17. An electric push rod 19 is fixedly installed on the bottom surface of the top plate 8. A movable rod 20 is fixedly installed at the output end of the electric push rod 19. A piston 21 is fixedly installed at the bottom end of the movable rod 20. The piston 21 is located inside the infusion cylinder 17 and fits against the inner wall of the infusion cylinder 17. The piston 21 facilitates the expulsion of the solution from the infusion cylinder 17. A support leg 22 is fixedly installed on the bottom surface of the workbench 1, and an anti-slip pad is fixedly installed on the bottom surface of the support leg 22. The anti-slip pad increases the friction area between the support leg 22 and the ground, making the device more stable during use. For stability, the lifting mechanism moves the connecting block 16, causing the infusion cylinder 17 to move downwards, allowing the infusion tube 18 to be inserted into the sealed volumetric flask 6. The valve 12 is then opened, allowing the urea solution in the storage tank 9 to enter the infusion cylinder 17 through the connecting tube 11. The valve 12 is then closed, and the piston 21 moves downwards via the electric push rod 19, thus injecting all the urea solution from the infusion cylinder 17 into the sealed volumetric flask 6, preventing dripping. The rotary motor 2 is then restarted to remove the sealed volumetric flask 6 filled with urea solution from below the infusion tube 18, and the empty sealed volumetric flask 6 is moved below the infusion tube 18 for dispensing, facilitating the placement and retrieval of the sealed volumetric flask 6 and improving dispensing efficiency.

[0020] In use: Place the sealed volumetric flask 6 into the placement slot 4, rotate the fixing bolt 5 so that one end of the fixing bolt 5 is tightly against the surface of the sealed volumetric flask 6 to fix the sealed volumetric flask 6. Start the rotary motor 2. The output end of the rotary motor 2 rotates, driving the turntable 3 to rotate, so that the sealed volumetric flask 6 moves directly below the infusion tube 18. Start the lifting motor 13. The output end of the lifting motor 13 rotates, driving the lead screw 14 to rotate, causing the threaded block 15 to move, which in turn drives the connecting block 16 to move, so that the infusion cylinder 17 moves downward, allowing the infusion tube 18 to be inserted into the sealed volumetric flask. Inside the volumetric flask 6, open valve 12. At this time, the urea solution in the storage tank 9 enters the infusion cylinder 17 through the connecting pipe 11. Close valve 12 and start electric push rod 19. Through electric push rod 19, piston 21 moves downward, so that all the urea solution in infusion cylinder 17 is injected into the inside of the sealed volumetric flask 6. Start rotary motor 2 again to remove the sealed volumetric flask 6 filled with urea solution from under infusion tube 18, and move the empty sealed volumetric flask 6 to under infusion tube 18 for dispensing, which is convenient for placement and handling, and improves dispensing efficiency.
