Description

Technical Field

[0001] This utility model belongs to the field of urea solution technology, specifically relating to a dilution device with a stirring mechanism. Background Technology

[0002] Urea solution is a liquid formed by dissolving urea in water. Urea solution dilution is the process of mixing a high-concentration urea solution with a dilution medium in a precise ratio to prepare a solution of the target concentration. Its core objective is to ensure that the concentration is accurate, the composition is uniform, and there is no impurity contamination after dilution, so as to meet the usage requirements of different scenarios such as agriculture, automobile exhaust treatment, medical treatment, and industry.

[0003] For example, in the Chinese utility model with announcement number CN222709521U, entitled "A Urea Solution Dilution and Mixing Device", it specifically includes a first input pipe, a first control mechanism arranged near the right side of the first input pipe, a second input pipe arranged below the first input pipe, and a second control mechanism arranged near the right side of the second input pipe. The above-mentioned prior art has a two-stage mixing and dilution function, which makes the mixing uniform and the dilution and mixing efficiency higher, which can meet the needs of large-scale production. Moreover, the dilution ratio can be controlled more precisely, and impurities in the urea solution can be filtered and purified, which is convenient for subsequent processing and use of the urea solution. However, the urea solution needs to be protected from contamination during dilution, so it is not convenient to thoroughly clean the dilution device. Therefore, a dilution device with a stirring mechanism is needed now. Utility Model Content

[0009] As a further optimization of this utility model, a first switching valve is fixedly installed in the middle of the diluent inlet pipe, and a filter screen fixed to the top cover by bolts is installed on the lower side of the first switching valve.

[0010] As a further optimization of this utility model, a second switching valve communicating with the housing of the dilution device is fixedly installed in the middle of the urea solution inlet pipe, and a third switching valve communicating with the housing of the dilution device is fixedly installed in the middle of the outlet pipe.

[0011] As a further optimization of this utility model, an exhaust pipe is fixedly connected to the other side of the top cover, and an exhaust valve is fixedly installed on the upper side of the exhaust pipe.

[0012] The beneficial effects of this utility model are as follows: By setting a stirring assembly inside the dilution device housing, this utility model facilitates the thorough mixing of urea solution and diluent. The stirring assembly is equipped with several sets of stirring blades of different models, which can improve the stirring effect.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 , Figure 3 , Figure 5 As shown, a dilution device with a stirring mechanism includes a dilution device housing 1, a top cover 2 on the upper side of the dilution device housing 1, handles 3 fixedly provided at both ends of the outer side of the top cover 2, and a sealing ring 4 fixedly provided at the lower outer end of the top cover 2. The outer side of the sealing ring 4 fits against the inner side of the dilution device housing 1. The top cover 2 is engaged with the dilution device housing 1. By holding the handles 3, the top cover 2 can be pulled upwards from the dilution device housing 1.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a diluent inlet pipe 5 is fixedly connected to one side of the top cover 2. The diluent used to dilute the urea solution is introduced into the dilution device shell 1 through the diluent inlet pipe 5. When adding materials, the calculated diluent is first poured into the dilution device shell 1, and then the high-concentration urea solution is slowly added to avoid the urea solution directly contacting the bottom of the tank and reducing local overheating. The urea solution will release heat slightly when it dissolves. Although it is not intense, the accumulation of high-concentration mother liquor may accelerate hydrolysis. Therefore, it is necessary to first add the diluent into the dilution device shell 1 through the diluent inlet pipe 5. A first switch valve 6 is fixedly installed in the middle of the diluent inlet pipe 5. The first switch valve 6 is opened when adding the diluent and closed after the addition is completed. A filter screen 7 is installed on the lower side of the first switch valve 6. The upper side of the filter screen 7 is fixed to the lower side of the top cover 2 by bolts. To avoid contamination of the urea solution during dilution, it is necessary to prevent impurities from entering the dilution device shell 1. The filter screen 7 is installed to filter the diluent added through the diluent inlet pipe 5 to prevent impurities from entering the dilution device shell 1.

[0023] like Figure 1 , Figure 3 As shown, a urea solution inlet pipe 8 is fixedly connected to one side of the dilution device housing 1. High-concentration urea solution is added into the dilution device housing 1 through the urea solution inlet pipe 8. A second switch valve 9 is fixedly installed in the middle of the urea solution inlet pipe 8. The second switch valve 9 is opened when adding high-concentration urea solution and closed after the addition is completed.

[0024] like Figure 3 , Figure 4 As shown, a servo motor 1001 is fixedly mounted on the upper side of the top cover 2. A connecting plate 1002 is fixedly mounted on the output shaft of the servo motor 1001. The connecting plate 1002 is located on the lower side of the top cover 2. A transmission rod 1003 is mounted on the lower side of the connecting plate 1002. A connecting plate 1002 is fixedly mounted on the upper side of the transmission rod 1003. The connecting plates 1002 on both are fixed together by several bolts. Several stirring blades 1004 are slidably mounted through the transmission rod 1003. A setter nut 1005 is provided on both the upper and lower sides of the stirring blades 1004. The setter nut 1005 is threaded to the transmission rod 1003. In this way, the stirring blades are... 1004 is fixed on the transmission rod 1003, which is equipped with several stirring blades 1004. Two stirring blades 1004 are of different sizes and stir the solution at the upper and lower ends inside the dilution device housing 1 to ensure that the solution is fully mixed and diluted. A scraper 1006 is fixed on the upper side of the transmission rod 1003. The outer side of the scraper 1006 is in contact with the inner side of the dilution device housing 1. When stirring and diluting the solution inside the dilution device housing 1, the scraper 1006 scrapes off the solution adhering to the inner wall of the dilution device housing 1, so that the adhering solution is mixed with other solutions, improving the dilution effect and preventing solution residue during unloading.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a liquid outlet pipe 11 is fixedly connected to the bottom side of the dilution device housing 1. A third switch valve 12 is fixedly installed in the middle of the liquid outlet pipe 11. After the urea solution is diluted, the third switch valve 12 is opened to allow the solution to be discharged from the liquid outlet pipe 11. An exhaust pipe 13 is fixedly connected to the other side of the top cover 2. An exhaust valve 14 is fixedly installed on the upper side of the exhaust pipe 13. Gas will be generated during the dilution process. In order to ensure the pressure inside the dilution device housing 1 is stable, an exhaust pipe 13 is set to exhaust gas. The exhaust valve 14 can be controlled to open and close to exhaust gas.

[0026] It should be noted that, in use, this dilution device with a stirring mechanism involves opening the first switch valve 6 to first add diluent into the dilution device housing 1 through the diluent inlet pipe 5. The diluent is filtered through the filter screen 7. After adding a certain amount of diluent, the first switch valve 6 is closed, and then the second switch valve 9 is opened to allow a high-concentration urea solution to be added into the dilution device housing 1 through the urea solution inlet pipe 8. After adding a certain amount of high-concentration urea solution, the second switch valve 9 is closed, and the servo motor 1001 is started. The output shaft of the servo motor 1001 drives the transmission rod 1003 to rotate, and the solution in the dilution device housing 1 is fully mixed and diluted by the stirring blade 1004. During the dilution process, the exhaust valve 14 is opened to discharge the generated gas through the exhaust pipe 13 to ensure stable pressure inside the dilution device housing 1. After the urea solution is diluted, the third switch valve 12 is opened to allow the solution to be discharged through the outlet pipe 11.

[0027] After diluting the urea solution once, the entire dilution device needs to be cleaned. Therefore, the entire dilution device needs to be disassembled. First, hold the handle 3 and pull the top cover 2 away from the outer shell 1 of the dilution device. Remove the filter screen 7 and then remove the connecting plate 1002. After removing the connecting plate 1002, remove the stabilizing nut 1005 and the stirring blade 1004 in sequence. Clean the components inside the dilution device one by one so that the dilution device can be thoroughly cleaned to avoid contamination that may affect the next dilution.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
