[0024] In actual use, when it is necessary to add liquid to the tank body 1 midway, first remove the liquid adding barrel 10 from the top of the cover 9, then press down the push rod 13 inserted in the push rod hole 14, so that the piston 12 moves to the bottom of the liquid adding barrel 10, and then insert the end of the liquid adding barrel 10 with the through hole 11 into the material barrel containing the liquid to be added, and ensure that the through hole 11 is completely immersed under the liquid surface, and then pull the push rod 13 upward to make the piston 12 move upward. Under the action of air pressure, the liquid to be added in the material barrel is drawn from the through hole 11 to the liquid adding barrel. The top cover 9 is pushed downwardly, and the height of the liquid adding barrel 10 is lowered, thereby pushing the cover 9 downwardly. After the height of the liquid adding barrel 10 is lowered to the point where the top of the through hole 11 is lower than the bottom of the top cover 2, the push rod 13 is pushed downwardly to make the piston 12 move downwardly, thereby pushing the liquid to be added in the liquid adding barrel 10 out of the liquid adding barrel 10 through the through hole 11 and adding it into the tank body 1. Therefore, it is very convenient to add liquid to the tank body 1 midway, and it is convenient to change the ratio of the liquid in the tank body 1.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to prevent the gas in the tank body 1 from leaking before and after the mid-way liquid addition and during the mid-way liquid addition process, a mid-way liquid addition reserved hole 3 is opened on the surface of the top cover 2, and a sealing cover 9 is movably connected in the mid-way liquid addition reserved hole 3. Two sets of hanging plates 6 are fixed to the bottom end of the top cover 2. The mid-way liquid addition reserved hole 3 is a circular hole structure. The two sets of hanging plates 6 are symmetrically distributed about the center line of the mid-way liquid addition reserved hole 3. The bottom ends of the two sets of mid-way liquid addition reserved holes 3 are fixed with The same group of spring plates 7 has a circular plate-like structure, a spring 8 is fixed to the top of the spring plate 7, the top of the spring 8 is fixed to the bottom of the cover 9, a first sealing groove 4 is opened on the inner wall of the midway liquid addition reserved hole 3, a first sealing ring 5 is fixed in the first sealing groove 4, the cover 9 has a circular sheet-like structure, the liquid adding barrel 10 has a cylindrical structure, the diameter of the cover 9 is equal to the diameter of the liquid adding barrel 10, and the diameters of the cover 9 and the liquid adding barrel 10 are equal to the aperture of the midway liquid addition reserved hole 3.

[0027] Since the liquid preparation tank is often used to prepare chemical and pharmaceutical products, and some chemical and pharmaceutical products will volatilize toxic and harmful gases during the preparation process, before and after the mid-way liquid addition to the tank body 1 and during the liquid addition process, it is necessary to prevent the toxic and harmful gases in the tank body 1 from leaking to the outside through the mid-way liquid addition reserved hole 3 opened on the surface of the top cover 2. Therefore, a sealing cover 9 is set in the mid-way liquid addition reserved hole 3. Before the mid-way liquid addition, the bottom end of the top cover 2 is provided with a spring plate 7 through a hanging plate 6. A spring 8 is arranged between the spring plate 7 and the sealing cover 9. Under the elastic action of the spring 8, the height of the sealing cover 9 is maintained in the midway liquid addition reserved hole 3. The diameter of the sealing cover 9 is the same as the aperture of the midway liquid addition reserved hole 3. At the same time, a first sealing groove 4 is opened on the inner wall of the top cover 2. A first sealing ring 5 is fixed in the first sealing groove 4. The first sealing ring 5 is made of a highly elastic material to fill the gap that may exist between the inner wall of the midway liquid addition reserved hole 3 and the side wall of the sealing cover 9 due to surface defects. Therefore, when liquid is not added, the sealing cap 9 blocks the midway liquid addition reserved hole 3 to prevent the gas in the tank body 1 from leaking from the midway liquid addition reserved hole 3; when liquid is added, the liquid adding barrel 10 moves downward to push the sealing cap 9 out of the midway liquid addition reserved hole 3, and the liquid adding barrel 10 is blocked in the midway liquid addition reserved hole 3. At the same time, the diameter of the liquid adding barrel 10 is the same as the aperture of the midway liquid addition reserved hole 3. Therefore, when liquid is added, the liquid adding barrel 10 can block the midway liquid addition reserved hole 3 to prevent the gas in the tank body 1 from leaking from the midway liquid addition reserved hole 3. The gas in the tank body 1 leaks from the mid-liquid addition reserved hole 3 when the mid-liquid addition is in progress; after the mid-liquid addition is completed, the liquid adding barrel 10 is slowly drawn upward from the mid-liquid addition reserved hole 3. As the liquid adding barrel 10 moves upward, the spring 8 pushes the sealing cover 9 upward synchronously under the action of its own elasticity. When the liquid adding barrel 10 is pushed out of the mid-liquid addition reserved hole 3, the sealing cover 9 has returned to the mid-liquid addition reserved hole 3, thereby preventing the gas in the tank body 1 from leaking from the mid-liquid addition reserved hole 3 after the mid-liquid addition is completed.

[0028] Embodiment 3

[0029] On the basis of Example 2, in order to prevent air pressure from leaking from the gap between the inner wall of the liquid adding barrel 10 and the piston 12, a second sealing groove 15 is opened on the surface of the piston 12. The second sealing groove 15 is an annular groove body. A second sealing ring 16 is fixed in the second sealing groove 15. One end of the second sealing ring 16 extends out of the second sealing groove 15 and abuts against the inner wall of the liquid adding barrel 10.

[0030] A second sealing groove 15 is provided on the surface of the piston 12, and a second sealing ring 16 is arranged in the second sealing groove 15. The second sealing ring 16 is made of a highly elastic material. The second sealing ring 16 is used to seal the gap between the inner wall of the liquid adding barrel 10 and the piston 12, thereby preventing the air pressure from leaking from the gap between the inner wall of the liquid adding barrel 10 and the piston 12.

[0031] Embodiment 4

[0032] On the basis of the second embodiment, in order to add liquid after the through hole 11 is completely inserted under the top cover 2, a scale line 17 is opened on the surface of the liquid adding barrel 10, and the distance between the bottom end of the scale line 17 and the top end of the through hole 11 is equal to the thickness of the top cover 2.

[0033] A scale line 17 is provided on the surface of the liquid adding barrel 10. After the liquid adding barrel 10 is inserted into 3, the liquid adding barrel 10 is continuously pressed downward until the bottom end of the scale line 17 is flush with the top end of the top cover 2 before adding liquid to the tank body 1. The distance between the scale line 17 and the through hole 11 is equal to the thickness of the top cover 2, so that liquid can be added after the through hole 11 is completely at the lower end of the top cover 2, thereby preventing the liquid in the liquid adding barrel 10 from being added on the surface of the first sealing ring 5 and being absorbed by the first sealing ring 5, which may cause a deviation between the actual added dose and the target dose.

[0034] In actual use, when it is necessary to add liquid to the tank body 1 midway, first remove the liquid adding barrel 10 from the top of the cover 9, then press down the push rod 13 inserted in the push rod hole 14, so that the piston 12 moves to the bottom end of the liquid adding barrel 10, and then insert the end of the liquid adding barrel 10 with the through hole 11 into the material barrel containing the liquid to be added, and ensure that the through hole 11 is completely immersed below the liquid surface, and then pull the push rod 13 upward to make the piston 12 move upward. Under the action of air pressure, the liquid to be added in the material barrel is drawn from the through hole 11 into the liquid adding barrel 10, and then put the liquid adding barrel 10 back to the top of the cover 9, press down hard on the liquid adding barrel 10, the height of the liquid adding barrel 10 drops, thereby pushing the cover 9 downward, and wait until the height of the liquid adding barrel 10 drops to the through hole 11 After the top end is lower than the bottom end of the top cover 2, the push rod 13 is pushed downward to make the piston 12 move downward, so that the liquid to be added in the liquid adding barrel 10 is pushed out from the liquid adding barrel 10 through the through hole 11 and added into the tank body 1, so that it is very convenient to add liquid to the tank body 1 midway, and it is convenient to change the ratio of the liquid in the tank body 1; since the liquid mixing tank is often used to mix chemical and pharmaceutical products, and some chemical and pharmaceutical products will volatilize toxic and harmful gases during the liquid mixing process, before and after the midway addition of liquid to the tank body 1 and during the liquid addition process, it is necessary to prevent the toxic and harmful gases in the tank body 1 from leaking to the outside from the midway addition reserved hole 3 opened on the surface of the top cover 2, therefore, a sealing cover 9 is set in the midway addition reserved hole 3, and before the midway addition of liquid, the bottom end of the top cover 2 A spring plate 7 is arranged through the hanging plate 6, and a spring 8 is arranged between the spring plate 7 and the sealing cover 9. Under the elastic action of the spring 8, the height of the sealing cover 9 is maintained in the mid-liquid addition reserved hole 3, and the diameter of the sealing cover 9 is the same as the aperture of the mid-liquid addition reserved hole 3. At the same time, a first sealing groove 4 is opened on the inner wall of the top cover 2, and a first sealing ring 5 is fixed in the first sealing groove 4. The first sealing ring 5 is made of highly elastic material to fill the gap between the inner wall of the mid-liquid addition reserved hole 3 and the side wall of the sealing cover 9 due to surface defects. Therefore, when no liquid is added, the sealing cover 9 blocks the mid-liquid addition reserved hole 3 to prevent the gas in the tank body 1 from leaking from the mid-liquid addition reserved hole 3; when adding liquid, the liquid adding barrel 10 moves downward to push the sealing cover 9 out When the liquid is added to the reserved hole 3 for midway liquid addition, the liquid adding barrel 10 is blocked in the reserved hole 3 for midway liquid addition. At the same time, the diameter of the liquid adding barrel 10 is the same as the aperture of the reserved hole 3 for midway liquid addition. Therefore, when adding liquid, the liquid adding barrel 10 can block the reserved hole 3 for midway liquid addition to prevent the gas in the tank body 1 from leaking from the reserved hole 3 for midway liquid addition when the liquid is added to the tank body 1; after the liquid is added to the tank body 1, the liquid adding barrel 10 is slowly drawn out from the reserved hole 3 for midway liquid addition. With the upward movement of the liquid adding barrel 10, the spring 8 pushes the cover 9 upward synchronously under the action of its own elasticity. When the liquid adding barrel 10 is pushed out from the reserved hole 3 for midway liquid addition, the cover 9 has returned to the reserved hole 3 for midway liquid addition to prevent the gas in the tank body 1 from leaking from the reserved hole 3 for midway liquid addition after the liquid is added to the tank body 1;A second sealing groove 15 is provided on the surface of the piston 12, and a second sealing ring 16 is provided in the second sealing groove 15. The second sealing ring 16 is made of a highly elastic material. The gap between the inner wall of the liquid adding barrel 10 and the piston 12 is blocked by the second sealing ring 16, thereby preventing the gas pressure from leaking from the gap between the inner wall of the liquid adding barrel 10 and the piston 12; a scale line 17 is provided on the surface of the liquid adding barrel 10. After the liquid adding barrel 10 is inserted into the tank 3, the liquid adding barrel 10 is continuously pressed downward until the bottom end of the scale line 17 is flush with the top end of the top cover 2 before adding liquid to the tank body 1. The distance between the scale line 17 and the through hole 11 is equal to the thickness of the top cover 2, so that the through hole 11 can be completely located at the lower end of the top cover 2 before adding liquid, thereby preventing the liquid in the liquid adding barrel 10 from being added to the surface of the first sealing ring 5 and being absorbed by the first sealing ring 5, resulting in a deviation between the actual added dose and the target dose. ;
