DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1, reference Figure 1-2 , a water-based solvent storage barrel, including a plastic barrel 7 and an upper cover 17 connected by a buckle.

[0028] A sealing plate 13 is threadedly connected to the inner side of the plastic barrel 7 below the upper cover 17, and the plastic barrel 7 is divided into two independent and closed spaces by the sealing plate 13. A feed pipe 16 is installed on the sealing plate 13. A plurality of groups of protective components 14 are distributed in a circular array on the upper end of the sealing plate 13. The protective components 14 include a positioning groove 141, a positioning column 142, a water collecting tray 143, a liquid outlet 144 and a tank body 145.

[0029] Reference Figure 5-6 The water collecting tray 143 is placed on the upper part of the sealing plate 13, the tank body 145 is inverted in the water collecting tray 143, the liquid outlet 144 is opened at the opening of the tank body 145, the positioning groove 141 is opened on the tank body 145, the positioning column 142 is connected to the upper cover 17, and the positioning column 142 extends to the inner side of the positioning groove 141, and the tank body 145 contains liquid, and the liquid contained in the tank body 145 is specifically silicone oil, and the liquid level of the silicone oil entering the water collecting tray 143 just covers the liquid outlet 144.

[0030] The plastic barrel 7 is made of plastic, which is corrosion-resistant and low-cost. Therefore, when the air inside the plastic barrel 7 is processed, due to the easy deformation of plastic, if the inside of the plastic barrel 7 is evacuated, not only will the air fail to be completely sucked out, but the plastic barrel 7 will also become shrunken.

[0031] Secondly, the gases that affect the storage of aqueous solvents are mainly oxygen and carbon dioxide. The effects of oxygen and carbon dioxide on aqueous solvents are mainly reflected in their chemical reactions and physical dissolution. Carbon dioxide is a gas that is easily soluble in water, and its solubility changes with changes in temperature and pressure. At normal temperature and pressure, a maximum of 0.169 mol / L of carbon dioxide is dissolved in an aqueous solution. After carbon dioxide is dissolved in water, it reacts with water to form carbonic acid. This is a reversible reaction, so the aqueous solution of carbon dioxide is not carbonic acid, but a mixture of carbon dioxide and water; the chemical reaction of carbon dioxide and oxygen with water may change the chemical properties of the aqueous solvent, such as affecting its pH and stability. At the same time, the dissolution of carbon dioxide and oxygen in water will affect the physical properties of the aqueous solvent, such as changing its density and viscosity.

[0032] To this end, a sealing plate 13 is threadedly connected near the upper end of the plastic barrel 7, and a plurality of protective components 14 are arranged on the sealing plate 13. The protective components 14 include a positioning groove 141, a positioning column 142, a water collecting tray 143, a liquid outlet 144 and a tank body 145. The interior of the tank body 145 is filled with silicone oil. The tank body 145 is inverted in the water collecting tray 143. At this time, the silicone oil in the tank body 145 enters the water collecting tray 143 through the liquid outlet 144 until the liquid outlet 144 at the lower end of the tank body 145 is blocked by the silicone oil in the water collecting tray 143. At this time, the tank body The pressure at the tank mouth 145, the pressure inside the tank body 145 and the external atmospheric pressure have reached a state of equilibrium, so water no longer flows downward. As the storage time becomes longer, part of the silicone oil in the water collecting tray 143 diffuses and disappears, exposing the liquid outlet 144 to the outside again. At this time, air re-enters the tank body 145 until the silicone oil replenished in the water collecting tray 143 blocks the liquid outlet 144 again, thereby forming a balance of pressures at multiple locations. In this way, reopening the upper cover 17 to replenish silicone oil and re-entering of external air when the upper cover 17 is opened can be avoided.

[0033] The reason why silicone oil can absorb oxygen and carbon dioxide is related to its chemical properties and physical structure. Silicone oil is an organic silicon compound with Si-O bonds in its molecular structure. The polarity of this bond makes silicone oil molecules have a certain polarity and can interact with polar molecules such as oxygen and carbon dioxide. There is a van der Waals force between silicone oil molecules and oxygen and carbon dioxide molecules. This force is a weak interaction force between molecules, which can make gas molecules adhere to the surface of silicone oil. The functional groups in silicone oil molecules may react chemically with oxygen and carbon dioxide to form chemical bonds, thereby achieving adsorption.

[0034] More importantly, silicone oil has a certain ability to inhibit mold and microorganisms, preventing microorganisms and bacteria from coming into contact with water-based dyes and causing solvent deterioration.

[0035] Example 2, reference Figure 3-4 The difference between this embodiment and embodiment 1 is that a base 15 is provided at the bottom of the plastic barrel 7 , a mounting hole 19 is provided at the upper end of the base 15 , and the plastic barrel 7 is placed inside the mounting hole 19 .

[0036] Two fixing frames 4 are symmetrically installed on the upper end of the base 15, and a driving member is arranged between the two fixing frames 4. Multiple groups of connecting ropes 6 are connected through the driving member, and a first magnetic ball 8 is movably connected to the bottom of the connecting rope 6. A floating member is arranged inside the plastic barrel 7, and a feedback component is connected through the floating member. The feedback component cooperates with the external first magnetic ball 8. The driving member includes a U-shaped support frame 2, a slot 3, a disc 5 and a motor 1; the slot 3 is opened at the top of the two fixing frames 4, the U-shaped support frame 2 is clamped on the inner side of the two slots 3, the motor 1 is arranged on the upper part of the U-shaped support frame 2, and the output shaft of the motor 1 is connected to the disc 5, and a plurality of connecting ropes 6 are fixedly installed at the bottom of the disc 5.

[0037] The floating member includes a floating plate 18 and floating bodies 11 distributed in a circular array around the floating plate 18. A regulating component 12 is also arranged on the upper part of the floating body 11. The feedback component includes a connecting rod 10 hinged at the bottom of the floating body 11. A second magnet ball 9 is rotatably arranged at the bottom of the connecting rod 10. The second magnet ball 9 corresponds to the first magnet ball 8 outside one by one, and the second magnet ball 9 and the first magnet ball 8 are in a state of mutual attraction.

[0038] When the storage environment temperature of the water-based dye is low, the water-based dye may condense inside the plastic barrel 7, which may cause the water-based dye to deteriorate.

[0039] To this end, considering the limited bearing capacity of the plastic barrel 7, two fixing frames 4 are installed on both sides thereof, and at the same time, the U-shaped support frame 2 equipped with the motor 1 is horizontally clamped between the two fixing frames 4 through the notch 3. In this way, when the motor 1 is running, the disc 5 at the lower end is driven to rotate, and a plurality of first magnet balls 8 distributed in a ring array at the lower end of the disc 5 will realize synchronous movement. A float 11 and a floating plate 18 are arranged inside the plastic barrel 7, and the float 11 and the floating plate 18 float on the upper surface of the water-based dye, and the lower end of the float 11 is movably connected to the second magnet ball 9 through a hinged connecting rod 10. When the first magnet ball 8 reaches the pre- When the first magnet ball 8 is in a fixed position, the first magnet ball 8 which is closest to the second magnet ball 9 will attract each other, so that the first magnet ball 8 is attracted to the second magnet ball 9 through the inner wall of the plastic barrel 7. When the first magnet ball 8 rotates, the second magnet ball 9 inside will also rotate on the inner side of the plastic barrel 7. The connecting rod 10 is arranged in a sheet shape. During the rotation of the second magnet ball 9, the connecting rod 10 will also be driven to rotate. In this way, the connecting rod 10 will be regularly stirred in the aqueous solvent. During the stirring process, the aqueous solvent can be prevented from freezing and condensing, thereby suppressing the problem of deterioration of the aqueous dye.

[0040] Example 3, reference Figure 7-8The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the regulating component 12 includes a cavity 121, a feed port 122, a diaphragm 123, a guide rod 124, a guide hole 125 and a notch 126, the cavity 121 is located inside the float 11, the feed port 122 is opened through the top of the cavity 121, the diaphragm 123 is slidably arranged on the inner side of the cavity 121, and a notch 126 is arranged between the two ends of the diaphragm 123 and the cavity 121.

[0041] The guide hole 125 is opened on the diaphragm 123, and the guide rod 124 is vertically arranged on the inner side of the cavity 121. When the diaphragm 123 moves, the guide rod 124 is located on the inner side of the guide hole 125. When the material enters the cavity 121 from the feed port 122, the position of the diaphragm 123 rises until the feed port 122 is blocked. When the first magnet ball 8 changes its position, a gap is set between the first magnet ball 8 and the outer wall of the fixing frame 4 and the plastic barrel 7.

[0042] Water-based dyes contain many ingredients. During storage, suspended matter often overflows from the dye and floats on the surface of the dye. If these suspended matter are not handled in time, the suspended matter will be adsorbed together with more dye particles in the water-based dye due to intermolecular forces.

[0043] To this end, a feed port 122 is provided at the upper end of the float 11, and the feed port 122 is connected to a cavity 121 disposed inside the float 11. When the float 11 rotates on the surface of the dye, part of the suspended matter on the surface of the dye can pass through the upper surface of the float 11. When the suspended matter rushes through the upper end of the float 11, the suspended matter will enter the cavity 121 from the feed port 122, and the suspended matter will pass through the gap 126 formed between the diaphragm sheet 123 and the cavity 121 and fall into the bottom of the cavity 121. The diaphragm sheet 123 has buoyancy. When the suspended matter collected inside the cavity 121 is When there are more and more suspended matter, the position of the diaphragm 123 will be lifted. During the lifting process, the guide hole 125 and the guide rod 124 cooperate with each other to ensure that the position of the diaphragm 123 will not be offset when it rises. When the suspended matter collected in the cavity 121 reaches a maximum value, the diaphragm 123 will block the feed port 122 from the lower end. In this way, the collected suspended matter will no longer overflow from the feed port 122. After the storage time is over, the sealing plate 13, the float 11 and the floating disc 18 can be cleaned and reused.

[0044] The working principle of the device is: The plastic barrel 7 is made of plastic, which has good recovery ability, corrosion resistance and low cost. Therefore, when the air inside the plastic barrel 7 is processed, due to the easy deformation of plastic, if the inside of the plastic barrel 7 is evacuated, not only the air cannot be completely sucked out, but also the plastic barrel 7 will become shrunken.

[0045] Secondly, the gases that affect the storage of aqueous solvents are mainly oxygen and carbon dioxide. The effects of oxygen and carbon dioxide on aqueous solvents are mainly reflected in their chemical reactions and physical dissolution. Carbon dioxide is a gas that is easily soluble in water, and its solubility changes with changes in temperature and pressure. At normal temperature and pressure, a maximum of 0.169 mol / L of carbon dioxide is dissolved in an aqueous solution. After carbon dioxide is dissolved in water, it reacts with water to form carbonic acid, which is a reversible reaction. Therefore, the aqueous solution of carbon dioxide is not carbonic acid, but a mixture of carbon dioxide and water. The chemical reaction of carbon dioxide and oxygen with water may change the chemical properties of the aqueous solvent, such as affecting its pH and stability. At the same time, the dissolution of carbon dioxide and oxygen in water will affect the physical properties of the aqueous solvent, such as changing its density and viscosity.

[0046] To this end, a sealing plate 13 is threadedly connected near the upper end of the plastic barrel 7, and a plurality of protective components 14 are arranged on the sealing plate 13. The protective components 14 include a positioning groove 141, a positioning column 142, a water collecting tray 143, a liquid outlet 144 and a tank body 145. The interior of the tank body 145 is filled with silicone oil. The tank body 145 is inverted in the water collecting tray 143. At this time, the silicone oil in the tank body 145 enters the water collecting tray 143 through the liquid outlet 144 until the liquid outlet 144 at the lower end of the tank body 145 is blocked by the silicone oil in the water collecting tray 143. At this time, the tank body The pressure at the tank mouth 145, the pressure inside the tank body 145 and the external atmospheric pressure have reached a state of equilibrium, so water no longer flows downward. As the storage time becomes longer, part of the silicone oil in the water collecting tray 143 diffuses and disappears, exposing the liquid outlet 144 to the outside again. At this time, air re-enters the tank body 145 until the silicone oil replenished in the water collecting tray 143 blocks the liquid outlet 144 again, thereby forming a balance of pressures at multiple locations. In this way, reopening the upper cover 17 to replenish silicone oil and re-entering of external air when the upper cover 17 is opened can be avoided.

There is a van der Waals force between silicone oil molecules and oxygen and carbon dioxide molecules. This force is a weak interaction force between molecules that can make gas molecules adhere to the surface of silicone oil. The functional groups in the silicone oil molecules may react chemically with oxygen and carbon dioxide to form chemical bonds, thereby achieving adsorption.

[0048] More importantly, silicone oil has a certain ability to inhibit mold and microorganisms, preventing microorganisms and bacteria from coming into contact with water-based dyes and causing solvent deterioration.

[0049] When the storage environment temperature of the water-based dye is low, the water-based dye may condense inside the plastic barrel 7, which may cause the water-based dye to deteriorate.

[0050] To this end, considering the limited bearing capacity of the plastic barrel 7, two fixing frames 4 are installed on both sides thereof, and at the same time, the U-shaped support frame 2 equipped with the motor 1 is horizontally clamped between the two fixing frames 4 through the notch 3. In this way, when the motor 1 is running, the disc 5 at the lower end is driven to rotate, and a plurality of first magnet balls 8 distributed in a ring array at the lower end of the disc 5 will realize synchronous movement. A float 11 and a floating plate 18 are arranged inside the plastic barrel 7, and the float 11 and the floating plate 18 float on the upper surface of the water-based dye, and the lower end of the float 11 is movably connected to the second magnet ball 9 through a hinged connecting rod 10. When the first magnet ball 8 reaches the pre- When the first magnet ball 8 is in a fixed position, the first magnet ball 8 which is closest to the second magnet ball 9 will attract each other, so that the first magnet ball 8 is attracted to the second magnet ball 9 through the inner wall of the plastic barrel 7. When the first magnet ball 8 rotates, the second magnet ball 9 inside will also rotate on the inner side of the plastic barrel 7. The connecting rod 10 is arranged in a sheet shape. During the rotation of the second magnet ball 9, the connecting rod 10 will also be driven to rotate. In this way, the connecting rod 10 will be regularly stirred in the aqueous solvent.

If these suspended matter are not handled in time, the suspended matter will be adsorbed together with more dye particles in the water-based dye due to intermolecular forces.

[0052] To this end, a feed port 122 is provided at the upper end of the float 11, and the feed port 122 is connected to a cavity 121 disposed inside the float 11. When the float 11 rotates on the surface of the dye, part of the suspended matter on the surface of the dye can pass through the upper surface of the float 11. When the suspended matter rushes through the upper end of the float 11, the suspended matter will enter the cavity 121 from the feed port 122, and the suspended matter will pass through the gap 126 formed between the diaphragm sheet 123 and the cavity 121 and fall into the bottom of the cavity 121.

After the storage time is over, the sealing plate 13, the float 11 and the floating disc 18 can be cleaned and reused.
