Specific implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] To solve the technical problems of how to effectively install and measure, as Figures 1-5 shown, the following preferred technical solutions are provided:

[0022] A raw material proportioning and mixing flowmeter for chemical production includes a reaction kettle 1. An elevated tank 3 is arranged at the upper end of the reaction kettle 1. A first water inlet pipe 2 is arranged between the reaction kettle 1 and the elevated tank 3. The upper and lower ends of the outer side of the first water inlet pipe 2 are respectively fixedly provided with a second water inlet pipe 4 and a third water inlet pipe 5. Second flanges 9 are fixedly provided at the adjacent ends of the second water inlet pipe 4 and the third water inlet pipe 5. A flowmeter 7 is arranged between the two second flanges 9. First flanges 8 are fixedly provided at both ends of the flowmeter 7. Positioning columns 11 are fixedly provided on both sides of the end of the first flange 8. Positioning holes 10 are symmetrically opened on both sides inside the second flange 9. An inclined block 17 is fixedly provided on the outer side of the second flange 9. An L-shaped inclined panel 13 is arranged at the edge of the end of the first flange 8. A spring 16 is arranged on the side of the L-shaped inclined panel 13. Manual valves 6 are fixedly installed on the first water inlet pipe 2, the second water inlet pipe 4, and the third water inlet pipe 5.

[0023] Specifically, the positioning posts 11 at both ends of the flowmeter 7 are sequentially sleeved in the corresponding positioning holes 10. During the sleeving process, the inclined surfaces of the inclined surface blocks 17 and the L-shaped inclined surface plate 13 will come into contact with each other. The L-shaped inclined surface plate 13 moves to one side under extrusion and compresses the spring 16. When the sleeving is completed, the inclined surface blocks 17 and the L-shaped inclined surface plate 13 are staggered from each other. Under the action of the spring 16 restoring deformation, the L-shaped inclined surface plate 13 returns to its original position and the inner side engages with the outer side of the inclined surface block 17. After the flowmeter 7 and the third water inlet pipe 5 are fixedly installed, the opening and closing of several manual valves 6 are controlled. First, the manual valve 6 on the first water inlet pipe 2 is closed, and the other manual valves 6 are all opened. Since this manual valve 6 is located between the water inlet end of the second water inlet pipe 4 and the water outlet end of the third water inlet pipe 5, the chemically raw materials that are proportionally mixed and stored in the high-level tank 3 flow by gravity in the direction of the arrow shown in the figure and enter the first water inlet pipe 2 through the water outlet end of the third water inlet pipe 5, and finally enter the reaction kettle 1. The purpose of this design is to quickly install the flowmeter 7, and then the mixed raw materials pass through the flowmeter 7 from bottom to top, improving the measurement accuracy.

[0024] Further, as Figure 3 and Figure 5 shown, the following preferred technical solutions are provided:

[0025] The positioning posts 11 and the inner sides of the positioning holes 10 are engaged with each other and are of matching sizes. The purpose of this design is to preliminarily position the installation of the flowmeter 7.

[0026] Further, as Figures 2-5 shown, the following preferred technical solutions are provided:

[0027] An extension plate 12 is formed and processed on the outer side of the first flange 8. A fixing plate 15 is fixedly provided at the edge of the end of the extension plate 12. A connecting rod 14 is slidably connected inside the fixing plate 15. One end of the connecting rod 14 is fixedly provided on the side surface of the L-shaped inclined surface plate 13. The spring 16 is fixedly connected between the side surface of the L-shaped inclined surface plate 13 and the side surface of the fixing plate 15. The L-shaped inclined surface plate 13 is in contact connection with the end of the first flange 8. The L-shaped inclined surface plate 13 is in contact connection with the inclined surface block 17. The spring 16 drives the inner side of the L-shaped inclined surface plate 13 to engage with the outer side of the inclined surface block 17. The purpose of this design is to drive the L-shaped inclined surface plate 13 and the inclined surface block 17 to engage with each other through the spring 16 to fix the flowmeter 7.

[0028] Further, as Figures 2-5 shown, the following preferred technical solutions are provided:

[0029] One end of the connecting rod 14 away from the L-shaped inclined panel 13 is fixedly provided with a rotating plate 18. A screw rod 19 is threadedly connected to the rotating plate 18. One end of the screw rod 19 is fixedly provided with a handle 20. A threaded hole 21 is formed in the side surface of the fixed plate 15. The screw rod 19 is threadedly connected to the inner side of the threaded hole 21. The purpose of such design is to fix the connecting rod 14 by connecting the screw rod 19 and the threaded hole 21, and further fix the position of the L-shaped inclined panel 13 to improve the installation stability of the flowmeter 7.

[0030] Further, as Figure 1 shown, the following preferred technical solutions are provided:

[0031] The upper end of the first water inlet pipe 2 is fixedly communicated with the middle part of the bottom end of the high-level tank 3. The bottom end of the first water inlet pipe 2 is fixedly communicated with the water inlet end of the reaction kettle 1. The second water inlet pipe 4 and the third water inlet pipe 5 are communicated with the first water inlet pipe 2. The purpose of such design is to ensure that the raw materials flow into the reaction kettle 1 from the high-level tank 3 by gravity.

[0032] Further, as Figure 1 shown, the following preferred technical solutions are provided:

[0033] The flowmeter 7 is vertically installed. The water inlet at the lower end of the flowmeter 7 is higher than the water inlet of the second water inlet pipe 4. The purpose of such design is to ensure that the raw materials pass through the inside of the flowmeter 7 from bottom to top, ensure the full pipe state inside the flowmeter 7, and thus ensure the measurement accuracy.

[0034] In summary: The positioning columns 11 at both ends of the flowmeter 7 are sequentially sleeved in the corresponding positioning holes 10. During the sleeving process, the inclined surfaces of the inclined blocks 17 and the L-shaped inclined panel 13 will come into contact with each other. The L-shaped inclined panel 13 moves to one side due to the extrusion and compresses the spring 16. When the sleeving is completed, the inclined blocks 17 and the L-shaped inclined panel 13 are staggered from each other. Under the action of the spring 16 restoring deformation, the L-shaped inclined panel 13 resets and the inner side is engaged with the outer side of the inclined block 17. After the flowmeter 7 and the third water inlet pipe 5 are fixedly installed, the opening and closing of several manual valves 6 are controlled. First, the manual valve 6 on the first water inlet pipe 2 is closed, and other manual valves 6 are all opened. Since this manual valve 6 is located between the water inlet end of the second water inlet pipe 4 and the water outlet end of the third water inlet pipe 5, the proportionally mixed chemical raw materials stored in the high-level tank 3 flow by gravity in the direction of the arrow shown in the figure and enter the first water inlet pipe 2 through the water outlet end of the third water inlet pipe 5, and finally enter the reaction kettle 1. The purpose of such design is to quickly install the flowmeter 7, and then the mixed raw materials pass through the flowmeter 7 from bottom to top to improve the measurement accuracy.
