DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0033] Please refer to Figures 1 to 13 shown in the drawings: Embodiment 1: The present application provides a moisture-proof and oxidation-resistant titanium dioxide storage device, which comprises a container assembly 1, the container assembly 1 comprises a storage container 101 and a negative pressure table 102, the negative pressure table 102 is fixedly installed on the top of the storage container 101; further comprising a cover assembly, the cover assembly is composed of an operating mechanism 2, a moisture-proof plugging mechanism 3 and a limiting mechanism 4; The operating mechanism 2 comprises an operating knob 201, a positioning knob 202 and a pressure disc 203, the positioning knob 202 is rotationally connected to the top of the operating knob 201, and the pressure disc 203 is axially inserted into the inside of the positioning knob 202; the moisture-proof plugging mechanism 3 comprises a plugging seat 301 and a piston block 302, the plugging seat 301 is rotationally connected to the inside of the operating knob 201, and the plugging seat 301 is screwed outside the bottle mouth of the storage container 101, the piston block 302 is axially inserted into the inside of the plugging seat 301; the limiting mechanism 4 comprises a linkage frame 401 and a control block 402, the linkage frame 401 is axially inserted into the inside of the operating knob 201, and the control block 402 is radially inserted into the inside of the operating knob 201.

[0034] In the embodiments of the present disclosure, the top of the linkage frame 401 is provided with a torsion top spring 4011, and the two ends of the torsion top spring 4011 abut against the top of the linkage frame 401 and the bottom of the pressure disc 203 respectively. In use, the closure assembly can detach the top of the container assembly 1. When the closure assembly 1 is installed on the container assembly 1, the inside of the container assembly 1 is sealed, avoiding the entry of external air into the inside of the container assembly 1, facilitating the transportation and storage of titanium dioxide. The closure assembly can enable the stable storage and transportation of titanium dioxide. When the closure assembly is detached from the container assembly, the titanium dioxide inside the storage container 101 can be taken out for use. The closure assembly has a limiting function, which can avoid the excessive tightening of the closure assembly, prevent the damage of the threads at the bottle opening part of the storage container 101, realize the sealing state of the inside of the container assembly 1, and facilitate the use.

[0035] In the embodiments of the present disclosure, the bottom of the linkage frame 401 is provided with a linkage rod 4012, the inside of the control block 402 is provided with an inclined linkage groove 4021, the linkage rod 4012 is inserted into the inside of the linkage groove 4021, the inside of the control block 402 is provided with a synchronous clamping block 4022, the side of the sealing rotary seat 301 is provided with a synchronous tooth groove 3011, the cross section of the block body of the synchronous clamping block 4022 and the cross section of the single tooth groove of the synchronous tooth groove 3011 are both right-angled triangles, and the synchronous clamping block 4022 is inserted into the inside of the synchronous tooth groove 3011. Under the action of the torsion top spring 4011, when the operation rotary block 201 is rotated in the loosening direction, the straight edge of the block body of the synchronous clamping block 4022 and the straight edge of the tooth groove of the synchronous tooth groove 3011 are clamped with each other. In use, when the closure assembly needs to be installed and tightened on the top of the storage container 101, the operation rotary block 201 can be rotated manually or by an electric wrench. In the initial tightening stage, because the resistance of the thread cooperation between the sealing rotary seat 301 and the bottle opening part of the storage container 101 is small, under the action of the torsion top spring 4011, the linkage rod 4012 is located at the bottom of the linkage groove 4021, so that the synchronous clamping block 4022 is inserted into the inside of the synchronous tooth groove 3011. When the operation rotary block 201 is rotated, the sealing rotary seat 301 can be driven to rotate synchronously by the extrusion and friction transmission of the inclined edge of the block body of the synchronous clamping block 4022 and the inclined edge of the tooth groove of the synchronous tooth groove 3011, so that the sealing rotary seat 301 can be screwed on the top of the bottle opening of the storage container 101. With the rotation of the sealing rotary seat 301, the tightening resistance of the sealing rotary seat 301 will gradually increase. When the tightening resistance is greater than the elastic force of the torsion top spring 4011, after the operation rotary block 201 continues to rotate, because the elastic force of the torsion top spring 4011 is not enough to maintain the extrusion and friction transmission of the inclined edge of the block body of the synchronous clamping block 4022 and the inclined edge of the tooth groove of the synchronous tooth groove 3011, the inclined edge of the block body of the synchronous clamping block 4022 and the inclined edge of the tooth groove of the synchronous tooth groove 3011 will extrude and avoid each other, so that the operation rotary block 201 cannot continue to drive the sealing rotary seat 301 to rotate synchronously. After that, the operation rotary block 201 will only rotate alone, thereby limiting the maximum tightening degree of the sealing rotary seat 301, which can stably maintain the sealing of the inside of the storage container 101, and also avoids the occurrence of phenomena such as thread damage, and the use is stable. In the process, because the inclined edge of the block body of the synchronous clamping block 4022 and the inclined edge of the tooth groove of the synchronous tooth groove 3011 will extrude and avoid each other, the synchronous clamping block 4022 will move outward. When the synchronous clamping block 4022 moves outward, the linkage groove 4021 can drive the linkage frame 401 to move upward and compress the torsion top spring 4011 through the linkage rod 4012, so that the device will not be stuck. When the closure assembly needs to be removed, the operation rotary block 201 can be reversed to complete the disassembly action. When the operation rotary block 201 is reversed, the straight edge of the block body of the synchronous clamping block 4022 can be clamped with the straight edge of the tooth groove of the synchronous tooth groove 3011, so that the operation rotary block 201 can stably drive the sealing rotary seat 301 to reverse to realize the loosening and disassembly operation when the operation rotary block 201 is reversed, which is convenient and flexible to use.

[0036] In the embodiment of the present disclosure, the side surface of the pressure disc 203 is provided with a threaded block 2031, and the threaded block 2031 is screwed in the inside of the positioning rotary ring 202. In use, the maximum tightening force of the plugging rotary seat 301 can be freely adjusted and used through the positioning rotary ring 202, which can be adapted to different types and materials of storage containers 101 for assembly and use, and has high adaptability. When the positioning rotary ring 202 is rotated alone, the positioning rotary ring 202 can drive the positioning pressure disc 203 to move up and down in the inside of the operation rotary block 201 to change the use position through the threaded block 2031. The change of the use position of the pressure disc 203 changes the initial extension length of the torsion top spring 4011, that is, when the block body bevel of the synchronous clamping block 4022 and the tooth groove bevel of the synchronous tooth groove 3011 are mutually extruded and avoided, the required tightening resistance of the plugging rotary seat 301, that is, the tightening force, is adjusted and controlled conveniently and flexibly.

[0037] In the embodiment of the present disclosure, the top of the piston block 302 is provided with a track column 3021, the columnar cross section shape of the track column 3021 is a regular polygon, the inside of the plugging rotary seat 301 is provided with a track groove 3012, and the track column 3021 is inserted into the inside of the track groove 3012. In use, the cover assembly also has the function of extracting the residual air in the inside of the container assembly 1, so that the inside of the container assembly 1 is in a negative pressure state, thereby effectively preventing the phenomenon of moisture, deterioration or oxidation of titanium dioxide during storage, and the storage is stable. When the plugging rotary seat 301 is loosened and does not reach the maximum tightening force, the function of the cover assembly for extracting residual air is not triggered. When the plugging rotary seat 301 does not reach the maximum tightening force, the plugging rotary seat 301 and the operation rotary block 201 are synchronously rotated, so that the piston block 302 cannot move in the inside of the piston cavity 3013 at this time, and the device cannot be stuck. At the same time, when the plugging rotary seat 301 does not reach the maximum tightening force, the inside of the storage container 101 is not in a stable sealing state, so the operation of extracting the air remaining in the inside of the storage container 101 is not needed at this time. The loosening action is to realize the disassembly between the cover assembly and the storage container 101, so the air extraction operation is not needed at this time. The design is reasonable and smooth.

[0038] In the embodiments of the present disclosure, the inside of the operation knob 201 is provided with a reciprocating column 211, and the outside of the column body of the reciprocating column 211 is provided with a "V"-shaped reciprocating groove 2011. There are a plurality of reciprocating grooves 2011 in the outer annular array of the reciprocating column 211, and the reciprocating grooves 2011 are connected end to end between adjacent reciprocating grooves 2011. The inside of the track column 3021 is provided with a reciprocating protrusion 3022, and the reciprocating protrusion 3022 is inserted into the inside of the reciprocating groove 2011. In use, when the closure assembly is installed and operated, the closure knob 301 reaches the maximum tightening force, and the operation knob 201 is continuously rotated to realize the function of extracting the residual air in the storage container 101. After the closure knob 301 reaches the maximum tightening force, the operation knob 201 is continuously rotated, and thereafter the operation knob 201 is rotated independently of the closure knob 301. Under the cooperation of the track column 3021 and the track groove 3012, the rotating state of the piston block 302 and the closure knob 301 is always the same, so that the piston block 302 cannot be rotated at this time. When the operation knob 201 is continuously rotated in the tightening direction, the reciprocating groove 2011 of the reciprocating column 211 can drive the piston block 302 to move up and down in the piston cavity 3013 through the reciprocating protrusion 3022, thereby realizing the function of extracting the residual air in the storage container 101. The inside of the container assembly 1 is in a negative pressure state, and the inside of the storage container 101 can be extracted to a suitable negative pressure value by observing the pressure change of the negative pressure gauge 102. The oxygen and water vapor content in the storage container 101 can be effectively reduced. Since titanium dioxide will be oxidized and deteriorated by oxygen, the extraction of air in the storage container 101 can reduce the oxygen content, thereby slowing down the oxidation reaction speed and prolonging the storage period of titanium dioxide. The reduction of water vapor content can significantly reduce the risk of titanium dioxide dampness, which is beneficial to the long-term preservation of the powder and has strong moisture-proof and antioxidant ability. At the same time, the extraction of residual air can remove dust, microorganisms and other impurities in the storage container 101, and maintain the purity of titanium dioxide.

[0039] In the embodiments of the present disclosure, the inside of the blocking rotary seat 301 is provided with a piston cavity 3013, and the piston block 302 is arranged in the inside of the piston cavity 3013. The bottom of the piston cavity 3013 is provided with a suction passage 3014, and the inside of the piston block 302 is provided with a discharge passage 3023. The inside of the suction passage 3014 and the inside of the discharge passage 3023 are both provided with a one-way valve 3024 for controlling the flow direction of the gas. The inside of the block at the top of the blocking rotary seat 301 and the inside of the operation rotary block 201 are both provided with an escape passage 2012. In use, in the operation of extracting the residual air in the storage container 101, when the piston block 302 moves upward in the inside of the piston cavity 3013, the residual air in the inside of the storage container 101 can enter the inside of the piston cavity 3013 through the suction passage 3014. When the piston block 302 moves downward in the inside of the piston cavity 3013, the extracted air in the inside of the piston cavity 3013 can be discharged in sequence through the discharge passage 3023 and the escape passage 2012, thereby realizing a complete suction and discharge process, and stably realizing the function of discharging the residual air in the inside of the storage container 101. The use is stable, and the one-way valve 3024 can limit the flow direction of the gas when the residual air in the inside of the storage container 101 is extracted and discharged. It can also ensure that the inside of the storage container 101 is always in a sealed and negative pressure state during storage, further improving the stability of the device.

[0040] The specific use and role of the embodiment are as follows: in the application, the titanium dioxide is poured into the inside of the storage container 101 for storage, the cover assembly can be assembled and disassembled on the top of the container assembly 1, and the inside of the container assembly 1 is sealed after the cover assembly 1 is assembled on the container assembly 1, so that the outside air cannot enter the inside of the container assembly 1, thereby facilitating the transportation and storage of the titanium dioxide. The titanium dioxide can be stably stored and transported. When the cover assembly is disassembled from the container assembly, the titanium dioxide in the inside of the storage container 101 can be taken out for use. The cover assembly has a limiting function, which can prevent the storage container 101 from being damaged due to excessive tightening of the cover assembly, and can realize the sealing state of the inside of the container assembly 1. When it is necessary to assemble and tighten the cover assembly on the top of the storage container 101, the operation rotating block 201 can be rotated by manual operation or through an electric wrench. In the initial tightening stage, the resistance of the sealing rotating seat 301 and the thread cooperation of the bottle opening part of the storage container 101 is small. At this time, the linkage rod 4012 is located at the bottom of the linkage groove 4021 under the action of the torsion top spring 4011, so that the synchronous clamping block 4022 is inserted into the inside of the synchronous tooth groove 3011. When the operation rotating block 201 rotates, the synchronous clamping block 4022 can be driven to rotate synchronously by the extrusion and friction transmission of the block body inclined edge of the synchronous clamping block 4022 and the tooth groove inclined edge of the synchronous tooth groove 3011, so that the sealing rotating seat 301 can be screwed on the top of the bottle opening of the storage container 101. With the rotation of the sealing rotating seat 301, the tightening resistance of the sealing rotating seat 301 will gradually increase. When the tightening resistance is greater than the elasticity of the torsion top spring 4011, after the operation rotating block 201 continues to rotate, the elasticity of the torsion top spring 4011 is not enough to maintain the extrusion and friction transmission of the block body inclined edge of the synchronous clamping block 4022 and the tooth groove inclined edge of the synchronous tooth groove 3011, so that the block body inclined edge of the synchronous clamping block 4022 and the tooth groove inclined edge of the synchronous tooth groove 3011 will be extruded and avoided, so that the operation rotating block 201 cannot continue to drive the synchronous rotation of the sealing rotating seat 301. After that, the operation rotating block 201 will only rotate alone, thereby limiting the maximum tightening degree of the sealing rotating seat 301, which can stably maintain the sealing of the inside of the storage container 101, and also avoids the phenomenon of thread damage and the like. The use is stable, and in the process, the synchronous clamping block 4022 will move outward due to the extrusion and avoidance between the block body inclined edge of the synchronous clamping block 4022 and the tooth groove inclined edge of the synchronous tooth groove 3011. When the synchronous clamping block 4022 moves outward, the linkage groove 4021 can drive the linkage frame 401 to move upward and compress the torsion top spring 4011 through the linkage rod 4012, so that the device will not be stuck. When it is necessary to disassemble the cover assembly, the operation rotating block 201 can be rotated in the reverse direction to complete the disassembly action. When the operation rotating block 201 is reversely rotated, the block body straight edge of the synchronous clamping block 4022 can be clamped with the tooth groove straight edge of the synchronous tooth groove 3011, so that the operation rotating block 201 can stably drive the sealing rotating seat 301 to reversely rotate to realize the loosening and disassembly operation.The maximum tightening force of the blocking rotary seat 301 can be freely adjusted by the positioning rotary ring 202, which can adapt to different types and materials of storage containers 101. When the positioning rotary ring 202 is rotated alone, the positioning rotary ring 202 can drive the positioning pressure disc 203 to move up and down inside the operating rotary block 201 through the threaded block 2031, changing the use position. The change of the use position of the pressure disc 203 changes the initial extension length of the torsion top spring 4011, that is, when the synchronous block 4022 block body bevel and the synchronous tooth groove 3011 tooth groove bevel are squeezed and avoided, the required tightening resistance of the blocking rotary seat 301, that is, the tightening force, the cover assembly also has the function of extracting the residual air in the container assembly 1, so that the container assembly 1 is in a negative pressure state, thereby effectively preventing the titanium dioxide from being damp, deteriorated or oxidized during storage, and the storage is stable. When the blocking rotary seat 301 is loosened and does not reach the maximum tightening force, the cover assembly will not trigger the function of extracting residual air. When the blocking rotary seat 301 does not reach the maximum tightening force, the blocking rotary seat 301 and the operating rotary block 201 are synchronously rotated, so that the piston block 302 cannot move inside the piston cavity 3013, and the device will not be stuck. At the same time, when the blocking rotary seat 301 does not reach the maximum tightening force, the inside of the storage container 101 is not in a stable sealing state, so there is no need to extract the air inside the storage container 101 at this time. The loosening action is to realize the disassembly of the cover assembly and the storage container 101, so there is no need to extract air at this time. When the cover assembly is installed and operated, the blocking rotary seat 301 reaches the maximum tightening force, and continues to rotate the operating rotary block 201 to realize the function of extracting residual air inside the storage container 101. After the blocking rotary seat 301 reaches the maximum tightening force, the operating rotary block 201 is independent of the blocking rotary seat 301, and under the cooperation of the track column 3021 and the track groove 3012, the rotating state of the piston block 302 is always the same as that of the blocking rotary seat 301, so that the piston block 302 cannot rotate at this time. When the operating rotary block 201 continues to rotate in the tightening direction, the reciprocating groove 2011 of the reciprocating column 211 can drive the piston block 302 to reciprocate up and down inside the piston cavity 3013 through the reciprocating protrusion 3022, thereby realizing the function of extracting residual air inside the storage container 101. The inside of the container assembly 1 is in a negative pressure state. By observing the pressure change of the negative pressure gauge 102, the inside of the storage container 101 can be extracted to a suitable negative pressure value, which can effectively reduce the oxygen and water content in the storage container 101. Since titanium dioxide will oxidize and deteriorate when it comes into contact with oxygen, extracting air from the storage container 101 can reduce the oxygen content, thereby slowing down the oxidation reaction and prolonging the storage period of titanium dioxide. The reduction of water content can significantly reduce the risk of titanium dioxide getting wet.The long-term storage of the powder is facilitated, the moisture resistance and oxidation resistance are very strong, the residual air in the storage container 101 can be removed to remove dust, microorganisms and other impurities, and the purity of the titanium dioxide is maintained. In the operation of extracting the residual air in the storage container 101, when the piston block 302 moves upward in the piston cavity 3013, the residual air in the storage container 101 can enter the piston cavity 3013 through the suction channel 3014, when the piston block 302 moves downward in the piston cavity 3013, the extracted air in the piston cavity 3013 can be discharged in sequence through the discharge channel 3023 and the escape channel 2012, so that a complete suction and discharge process is realized, the function of discharging the residual air in the storage container 101 is stably realized, the use is stable, and the one-way valve 3024 can limit the flow direction of the gas when the residual air in the storage container 101 is extracted and discharged, and can also ensure that the storage container 101 is always in a sealed and negative pressure state during storage.
