It is also unable to accurately control the dilution concentration and is unable to meet large-scale, high-efficiency production requirements. In addition, during the dilution and mixing process, urea solution and dilution water contain condensed impurities.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2 The utility model discloses a urea solution dilution and mixing device, comprising a first input pipe 1, a first manual ball valve 2 is installed on the first input pipe 1 near the left side, a first control mechanism 3 is arranged on the first input pipe 1 near the right side, a second input pipe 4 is arranged on the lower side of the first input pipe 1, a second manual ball valve 5 is installed on the second input pipe 4 near the left side, a second control mechanism 6 is arranged on the second input pipe 4 near the right side, the right ends of the first input pipe 1 and the second input pipe 4 are both connected with the left side wall of the filter cartridge 7, and the upper and lower sides of the filter cartridge 7 are both open structures, a filter mesh sleeve 8 is fixedly installed on the inner wall of the filter cartridge 7 near the middle position, a sealing cover 9 is threadedly installed on the upper surface of the filter cartridge 7, a mixing mechanism 10 is arranged on the lower surface of the sealing cover 9, a connecting pipe 11 is fixedly installed on the right side surface of the filter cartridge 7, a static mixer 12 is installed on the right side surface of the connecting pipe 11, and an output pipe 13 is installed on the right liquid outlet of the static mixer 12.

[0020] Specifically, the first control mechanism 3 includes an electric regulating valve 301 , a flow meter 302 and a check valve 303 , and the electric regulating valve 301 , the flow meter 302 and the check valve 303 are fixedly installed on the first input pipe 1 in sequence from left to right.

[0021] In this embodiment, the electric regulating valve 301 can adjust the flow rate of the urea solution in the first input pipe 1, the flow meter 302 counts the flow of the urea solution, and the check valve 303 prevents the urea solution from flowing back.

[0022] Specifically, the second control mechanism 6 has the same structure as the first control mechanism 3 .

[0023] In this embodiment, the second control mechanism 6 can adjust the flow rate of the dilution water in the second input pipe 4, perform statistics on the flow rate, and avoid backflow of the dilution water.

[0024] Specifically, a rectangular opening 14 is formed on the left side wall of the filter mesh sleeve 8 at positions corresponding to the first input pipe 1 and the second input pipe 4 .

[0025] In this embodiment, the rectangular opening 14 enables the urea solution input from the first input pipe 1 and the dilution water input from the second input pipe 4 to flow to the mixing mechanism 10 better.

[0026] Specifically, the mixing mechanism 10 includes a transmission rod 101, a bearing 102, a turbine blade 103, a stirring blade 104 and a scraper 105. The transmission rod 101 is installed on the lower surface of the sealing cover 9 through the bearing 102. The transmission rod 101 is provided with turbine blades 103 at positions corresponding to the first input pipe 1 and the second input pipe 4. The stirring blades 104 are evenly fixedly installed on the left and right sides of the transmission rod 101 from top to bottom.

[0027] In this embodiment, the bearing 102 enables the transmission rod 101 to have a rotation function. When the upper and lower turbine blades 103 are driven to rotate by the urea solution input by the first input pipe 1 and the dilution water input by the second input pipe 4, the stirring blade 104 mixes the urea solution and the dilution water, and the stirring blade 104 drives the scraper 105 to rotate, and the scraper 105 can scrape off the impurities filtered on the inner wall of the filter mesh sleeve 8.

[0028] Specifically, a plug 15 is threadedly mounted on the lower surface of the filter cartridge 7 .

[0030] When in use, the first manual ball valve 2 on the first input pipe 1 is opened, and the external controller opens the electric regulating valve 301 in the first control mechanism 3, so as to adjust the flow rate of the urea solution in the first input pipe 1, and the flow meter 302 counts the flow rate of the urea solution. The second manual ball valve 5 on the second input pipe 4 is opened, and the external controller can adjust the flow rate of the dilution water in the second input pipe 4 through the second control mechanism 6, count the flow rate, and avoid the backflow of the dilution water, so that the urea solution with a corresponding flow rate flows into the filter cartridge 7 through the first input pipe 1, and the dilution water with a corresponding flow rate flows into the filter cartridge 7 through the second input pipe 4. The filter mesh sleeve 8 can filter the impurities in the urea solution and the dilution water entering the filter cartridge 7, and the bearing 102 in the mixing mechanism 10 is used to filter the impurities in the urea solution and the dilution water. The transmission rod 101 has a rotation function. When the upper and lower turbine blades 103 are driven to rotate by the urea solution input by the first input pipe 1 and the dilution water input by the second input pipe 4, the stirring blade 104 mixes the urea solution and the dilution water, and the stirring blade 104 drives the scraper 105 to rotate. The scraper 105 can scrape off the impurities filtered on the inner wall of the filter mesh sleeve 8. The initially diluted and mixed urea solution flows into the static mixer 12 through the connecting pipe 11, and then the urea solution is mixed again by the static mixer 12. The mixed urea solution is discharged through the output pipe 13, so that the dilution mixing device has a double mixing and dilution function, so that the mixing is uniform, and the dilution mixing efficiency is higher, which can meet the needs of large-scale production, and the dilution ratio can be more accurately controlled, and the production quality is better.

[0031] In summary, the urea solution dilution and mixing device has a double mixing and dilution function, which makes the mixing uniform and the dilution and mixing efficiency higher, can meet the needs of large-scale production, and the dilution ratio can be more accurately controlled, and the impurities in the urea solution can be filtered and purified, which is convenient for the subsequent processing and use of the urea solution.
