[0021] As Figures 1-4 shown, an addition structure of concentrated sulfuric acid for the acidolysis reaction of titanium dioxide includes a storage bottle 1, a sealing cap 2 is screwed to the top of the storage bottle 1, a metering mechanism 3 is installed outside the storage bottle 1, an air exchange component 4 is installed at a position near the edge of the top of the storage bottle 1, the metering mechanism 3 includes a metering cylinder 5 and an infusion tube 6, the infusion tube 6 is fixedly installed on the inner wall of the storage bottle 1, a liquid outlet tube 7 is installed at the top end of the infusion tube 6, the metering cylinder 5 is installed outside the storage bottle 1, and a gas transmission tube 8 is connected and installed between the top end of the storage bottle 1 and the outer bottom end of the metering cylinder 5. A first screw 9 is movably installed through the inside of the metering cylinder 5, a first knob 10 is fixedly installed at the top end of the first screw 9, a piston 11 is movably installed at the bottom end of the first screw 9 and inside the metering cylinder 5, and a scale window 12 is opened on the periphery of the metering cylinder 5.

[0022] In this embodiment, the inside of the storage bottle 1 and the metering cylinder 5 are in mutual communication through the gas transmission tube 8. The first screw 9 is threadedly connected through the inside of the metering cylinder 5 and is arranged to slide up and down through the threaded connection of the first screw 9, which is convenient for adjusting the air pressure inside the metering cylinder 5.

[0023] In this embodiment, the piston 11 is arranged to slide up and down inside the metering cylinder 5. The bottom end of the first screw 9 passes through the top end of the piston 11 and is connected by a bearing. By lifting and lowering the piston 11, the air pressure inside the metering cylinder 5 is changed, so that air is conveyed into the storage bottle 1 to adjust the amount of concentrated sulfuric acid added.

[0024] In this embodiment, the ventilation component 4 includes a ventilation pipe 13. The ventilation pipe 13 is installed through the top of the storage bottle 1 and between the air delivery pipes 8. Two fixed disks 14 are fixedly installed inside the ventilation pipe 13. A number of through holes 15 are provided in the upper and lower parts penetrating through the two fixed disks 14. A second screw rod 16 is movably installed at the central position inside the two fixed disks 14. First sealing plugs 17 and second sealing plugs 18 are respectively fixedly installed at the positions near the top and bottom of the periphery of the second screw rod 16. A second knob 19 is installed at the top of the second screw rod 16. The upper and lower parts of the ventilation pipe 13 are alternately opened and closed by the first sealing plugs 17 and the second sealing plugs 18, so that the metering cylinder 5 is ventilated and used in a circulating and metering manner.

[0025] In this embodiment, the two fixed disks 14 are symmetrically arranged with each other. The fixed disks 14 are fixedly installed inside the ventilation pipe 13. Air enters the ventilation pipe 13 through the air delivery pipe 8 and circulates through the through holes 15 in the two fixed disks 14.

[0026] In this embodiment, the second screw rod 16 penetrates through the two fixed disks 14 and is in threaded connection. The first sealing plugs 17 and the second sealing plugs 18 are respectively located at the positions near the top and bottom inside the ventilation pipe 13 and are matched with each other. The first sealing plug 17 is used to open or close the bottom of the ventilation pipe 13, and the second sealing plug 18 is used to open or close the top of the ventilation pipe 13.

[0027] It should be noted that the present utility model is an adding structure for concentrated sulfuric acid in the acidolysis reaction of titanium dioxide. When in use, first, concentrated sulfuric acid is added into the storage bottle 1 and sealed by the sealing cover 2. One end of the liquid outlet pipe 7 is connected to the titanium dioxide enzyme reaction tank. When performing quantitative addition, by rotating the first knob 10, the first screw rod 9 rotates and drives the piston 11 to slide downward under the action of the thread, compressing the air at the bottom end inside the metering cylinder 5 and delivering it to the storage bottle 1 through the air delivery pipe 8, increasing the air pressure inside the storage bottle 1, so that the concentrated sulfuric acid enters the infusion pipe 6 and is delivered to the liquid outlet pipe 7, and the concentrated sulfuric acid is added to the titanium dioxide enzyme reaction tank for reaction. The lifting of the piston 11 is adjusted through the scale window 12, and thus the amount of concentrated sulfuric acid added is adjusted. When the piston 11 descends to the bottom end of the metering cylinder 5, by rotating the second knob 19, the second screw rod 16 rotates and drives the first sealing plugs 17 and the second sealing plugs 18 to slide upward under the action of the thread. The second sealing plug 18 enters the inside of the ventilation pipe 13 for sealing. Continuing to slide upward makes the second sealing plug 18 completely enter the ventilation pipe 13, and thus the first sealing plug 17 disengages from the ventilation pipe 13, opening the top of the ventilation pipe 13. External air enters the metering cylinder 5 through the ventilation pipe 13 and the air delivery pipe 8. By rotating the first screw rod 9, the piston 11 is driven to slide upward for another quantitative addition.

[0028] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
