DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

However, in the process of fluid transportation, the factors that affect the change in liquid flow rate in the pipeline include not only the power of the water pump, but also the height of the water pump installation position, the connection method of the water pump, etc. The previous demonstration methods could not show the impact of other factors on the liquid flow rate.

[0042] Therefore, in order to solve the above problems, the present invention provides Figure 1-11 A liquid delivery teaching demonstration system for intelligent food processing shown in the figure comprises a transparent first liquid storage tank 1, a second liquid storage tank 2 and a third liquid storage tank 3, the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3 are placed side by side, and the liquid for food processing is stored in the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3, and because the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3 are made of transparent acrylic material, it is convenient for students to visually observe the liquid inside during the demonstration;

[0043] Moreover, the present invention can be used to display different fluids. When changing the fluid for display, the inside of the fluid needs to be cleaned. In order to facilitate cleaning, Figure 1 and 10 As shown, the top of the first liquid storage tank 1, the top of the second liquid storage tank 2 and the top of the third liquid storage tank 3 are all fixedly connected with a feed pipe 4, and the cleaning water can be injected into the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3 through the feed pipe 4. In order to facilitate the discharge of water after cleaning, as shown in FIG. Fig.10 As shown, the bottom of the first liquid storage tank 1, the bottom of the second liquid storage tank 2 and the bottom of the third liquid storage tank 3 are all fixedly connected with a discharge pipe 5, and a valve is fixedly provided on the outer wall of each discharge pipe 5. When discharging sewage, it is only necessary to open the valve on the discharge pipe 5, and the sewage can be discharged through the discharge pipe 5;

[0044] In order to monitor the pH value of the liquid in the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3, Fig.10 As shown, pH sensors 6 are provided at the bottom of the first liquid storage tank 1, the bottom of the second liquid storage tank 2 and the bottom of the third liquid storage tank 3, and the probes of the three pH sensors 6 extend into the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3 respectively. The provided pH sensors 6 can be used to detect the pH values ​​of the liquids in the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3, and by designing the pH sensors 6 at the bottom of the tank body, the pH sensors 6 can still detect the liquid when a small amount of liquid remains in the tank body.

[0045] In the process of conveying liquid, it is necessary to enable the liquid to circulate among the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3. Therefore, in order to connect the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3, Figure 1-4 As shown, a first bellows 7 is fixedly connected to the bottom of one side of the first liquid storage tank 1, one end of the first bellows 7 is connected to a first water pump 8, the water outlet of the first water pump 8 is connected to a second bellows 9, one end of the second bellows 9 is connected to the inside of the second liquid storage tank 2, the first liquid storage tank 1 and the second liquid storage tank 2 are connected through the first bellows 7, the first water pump 8 and the second bellows 9, and the first water pump 8 provides power to drive liquid circulation;

[0046] like Figure 2 As shown, a third bellows 10 is fixedly connected to one side of the bottom of the second liquid storage tank 2, one end of the third bellows 10 is connected to the second water pump 11, the water outlet of the second water pump 11 is connected to the fourth bellows 12, one end of the fourth bellows 12 is connected to the inside of the third liquid storage tank 3, the second liquid storage tank 2 and the third liquid storage tank 3 are connected through the third bellows 10, the second water pump 11 and the fourth bellows 12, and the second water pump 11 provides power for liquid circulation. At this time, the second water pump 11 and the first water pump 8 are connected in series in the liquid flow pipeline. In addition to this method, the second water pump 11 can also be connected in parallel in the liquid delivery pipeline where the first water pump 8 is located, such as Figure 4 As shown;

[0047] In order to facilitate the connection of the second water pump 11 in parallel with the liquid delivery pipeline, Figure 2 As shown, the first bellows 7 is fixedly connected to the rear side with a first branch pipe 31, and the second bellows 9 is fixedly connected to the rear side with a second branch pipe 32. When the second water pump 11 is connected in parallel, it is only necessary to remove the second water pump 11 from between the third bellows 10 and the fourth bellows 12, and then install it between the first branch pipe 31 and the second branch pipe 32.

[0048] In order to facilitate the installation and disassembly of pipelines in the present invention, Figure 2 and 11As shown, the connection ends of the first bellows 7, the second bellows 9, the third bellows 10, the fourth bellows 12, the first branch pipe 31 and the second switch valve 33 are all configured as flange interfaces connected by bolts. By designing the pipeline connections as flange interfaces, they can be easily disassembled and reassembled. Moreover, the outer ends of the first bellows 7, the second bellows 9, the third bellows 10 and the fourth bellows 12 are all fixedly provided with a first switch valve 29 for liquid circulation. The first switch valve 29 is arranged on one side of the flow meter 30. By arranging multiple first switch valves 29, the flow of the liquid can be controlled. Moreover, the outer ends of the first bellows 7, the second bellows 9, the third bellows 10 and the fourth bellows 12 are all provided with a flow meter 30 for detecting the flow rate of the liquid. By using the flow meter 30, the flow rate of the liquid in the pipeline can be intuitively reflected;

[0049] When the second water pump 11 is connected in series in the pipeline, in order to prevent the liquid from flowing out through the first branch pipe 31 and the second branch pipe 32, as shown in FIG. Figure 2 As shown, the outer ends of the first branch pipe 31 and the second branch pipe 32 are fixedly provided with a second switch valve 33 for controlling the flow of liquid. By providing the second switch valve 33, the first branch pipe 31 and the second branch pipe 32 can be conveniently blocked when they are not in use;

[0050] A connecting pipe 41 is fixedly connected between the first liquid storage tank 1 and the third liquid storage tank 3, and a third switch valve 42 for controlling the flow of liquid is fixedly provided at the outer end of the connecting pipe 41. The first liquid storage tank 1 and the third liquid storage tank 3 are connected through the connecting pipe 41, so that a closed loop can be formed between the first liquid storage tank 1, the second liquid storage tank 2 and the third liquid storage tank 3, thereby realizing the circulation of liquid and facilitating demonstration.

[0051] In addition to being able to adjust the flow rate of the liquid in the pipeline by changing the power of the second water pump 11 and the first water pump 8, the present invention can also Figure 8 and 9 As shown, the first water pump 8 and the second water pump 11 are both provided with a lifting mechanism outside thereof that can drive them to move up and down. By adjusting the height of the first water pump 8 and the second water pump 11 by using the lifting mechanism, the influence on the conveying efficiency can be studied;

[0052] Specifically, the lifting mechanism includes two water pump mounting plates 13 respectively arranged at the bottom of the first water pump 8 and the second water pump 11, the two water pump mounting plates 13 are respectively connected to the first water pump 8 and the second water pump 11 by bolts, the front and rear sides of the water pump mounting plates 13 are fixed with handles 14, the bottom of the water pump mounting plates 13 is provided with a movable plate 15, the four corners of the movable plate 15 are penetrated by threaded rods 17, the threaded rods 17 are connected to the water pump mounting plates 13 by threads, the bottom ends of the threaded rods 17 are movably connected to the bottom plate 16 by bearings, the four corners of the bottom of the bottom plate 16 are fixed with movable wheels 26, the front side of the bottom plate 16 is fixed with There is a push-pull handle, which is mainly used to facilitate the movement of the second water pump 11 to push the device to move. The top of the threaded rod 17 is penetrated by a top plate 18, and the threaded rod 17 is movably connected to the top plate 18 through a bearing. The top of the threaded rod 17 passes through the top plate 18 and extends out of the top of the top plate 18. A forward and reverse motor 19 is provided on the top of one of the threaded rods 17 to drive it to rotate, and a pulley 20 is fixed on the top of each threaded rod 17. A belt 21 is provided between the two pulleys 20 on the front side and the two pulleys 20 on both sides, and the pulleys 20 and the belt 21 are both arranged on the top of the top plate 18;

[0053] During the conveying process, the forward and reverse motor 19 in the lifting mechanism can be started, and the forward and reverse motor 19 can be used to drive one of the threaded rods 17 to rotate. Since a pulley 20 and a belt 21 are installed between the four threaded rods 17, the remaining three threaded rods 17 can be driven to rotate together under the condition that one threaded rod 17 rotates. Moreover, the threaded rod 17 is connected to the movable plate 15 by a thread, so the threaded rod 17 can drive the movable plate 15 to move up and down, and then the water pump mounting plate 13 and the second water pump 11 or the first water pump 8 can be driven to move up and down through the movable plate 15, so as to adjust the position height of the second water pump 11 and the first water pump 8. Moreover, since the pipes on both sides of the first water pump 8 and the second water pump 11 are corrugated pipes, they can be telescopically adjusted, so the up and down movement of the first water pump 8 and the second water pump 11 will not be affected. In the process of the up and down movement of the first water pump 8 and the second water pump 11, the flow meter 30 can reflect the change of the liquid flow rate in the pipeline.

[0054] In the process of adjusting the height of the first water pump 8 and the second water pump 11, in order to facilitate people to clearly observe the height changes, such as Fig. 9As shown, a height monitoring indicating assembly for displaying the heights of the first water pump 8 and the second water pump 11 in the vertical direction is provided on the top of the bottom plate 16.

The top of the scale 22 is fixedly connected to the bottom of the top plate 18. A bracket 23 is provided on one side of the scale 22. The bottom end of the bracket 23 is fixedly connected to the top of the moving plate 15. An indicating arrow 24 pointing to the scale 22 is provided on the top of the bracket 23. Since the indicating arrow 24 is fixed to the top of the moving plate 15 through the bracket 23, it can move up and down synchronously with the first water pump 8 or the second water pump 11. However, since the indicating arrow 24 is fixed between the bottom plate 16 and the top plate 18, the position of the top plate 18 will not change. Moreover, after the indicating arrow 24 moves, it will indicate different positions on the scale 22, thereby intuitively showing the changes in the heights of the first water pump 8 and the second water pump 11.
