[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1 - Figure 8 One embodiment of the present invention is: a polymerization inhibitor detection device with an intelligent sensor, comprising: a storage tank 1, wherein butadiene is stored in the storage tank 1, and an intelligent sensor is provided inside the storage tank 1, wherein the intelligent sensor is used to detect the concentration inside the storage tank 1; a valve 2, wherein the valve 2 is fixedly mounted on the surface of the storage tank 1, and the valve 2 is used to control the injection of the additive solution; an addition tank 3, wherein the addition tank 3 is fixedly mounted on the top of the valve 2; a safety cover 4, wherein the safety cover 4 is provided on the top of the addition tank 3, and a round hole is provided on the top of the safety cover 4; a motor 5, wherein the motor 5 is fixedly mounted on the top of the safety cover 4; a stirring rod 6, wherein the stirring rod 6 is fixed Fixedly installed at the output end of the motor 5, the stirring rod 6 rotates and passes through the bottom of the safety cover 4, and the stirring rod 6 is used to mix the additive solution; the lifting frame 7, the lifting frame 7 slides and passes through the bottom of the stirring rod 6, and the bottom of the lifting frame 7 is rotatably installed with a swivel; No. 1 spring 8, No. 1 spring 8 is arranged between the lifting frame 7 and the stirring rod 6; filter plate 9, two filter plates 9 are fixedly installed on the inner wall of the lifting frame 7, and the filter plate 9 is used to block crystals. By setting the filter plate 9 to intercept the inhibitor crystals, it is prevented from clogging the valve 2, ensuring the accuracy of the additive injection amount. The intelligent sensor can monitor the content of the additive in real time to ensure accurate addition.

[0029] An inserting plate 10 is fixedly installed on the bottom of the safety cover 4, and a clamping plate 11 is fixedly installed on the circumferential surface of the adding tank 3. Rubber sheets 12 are fixedly installed on both sides of the inner wall of the clamping plate 11. The inserting plate 10 is in contact with the rubber sheet 12. By arranging the rubber sheet 12 inside the clamping plate 11, it is ensured that the inserting plate 10 is closely fitted with the clamping plate 11, and moderate resistance can be provided when pulling to prevent the clamping plate 11 from accidentally loosening.

[0030] The rotating ring at the bottom of the lifting frame 7 contacts the inner wall of the adding tank 3, and the two rubber sheets 12 are symmetrically arranged. By symmetrically arranging the rubber sheets 12, the stability of the contact between the card board 11 and the rubber sheets 12 is ensured, thereby improving the stability of the card board 11.

[0031] When the present embodiment is working, first check whether the valve 2 is in the closed state. After confirming that it is closed, inject the liquid polymerization inhibitor and the solvent into the adding tank 3, start the motor 5, and its output end drives the stirring rod 6 to rotate. The stirring rod 6 rotates to mix the liquid polymerization inhibitor and the solvent. At the same time, the intelligent sensor detects the concentration of the mixed solution. When the concentration is too high, the liquid polymerization inhibitor is automatically added to reduce the concentration of the solution. The intelligent sensor in the present embodiment can be a pressure sensor. When the solution concentration is high, the pressure sensor is subjected to a greater force. During the stirring process, the stirring rod 6 drives the lifting frame 7 to rotate synchronously. At this time, the No. 1 spring 8 in the compressed state exerts a continuous downward force on the lifting frame 7. The pressure keeps the rotating ring at the bottom of the lifting frame 7 in close contact with the adding tank 3, and the friction between the rotating ring and the inner wall of the adding tank 3 prevents the rotating ring from rotating synchronously with the lifting frame 7, thereby improving the stability of the lifting frame 7. At the same time, the rotation of the lifting frame 7 drives the filter plate 9 to rotate. The filter plate 9 allows the mixed additive solution to pass through during rotation, but blocks the inhibitor crystals precipitated due to low temperature. The blocked crystals gradually dissolve under the action of solvent flushing and stirring, and are converted back into liquid state, and finally pass through the filter plate 9 smoothly, ensuring that the solution is uniform and free of solid residues. After sufficient mixing, open the valve 2 and inject the additive solution into the storage tank 1, effectively suppressing the spontaneous polymerization of butadiene in the storage tank 1. Polymerization reaction, when the injection of additive solution is completed, valve 2 must be closed in time, and inhibitor crystals must be intercepted by setting a filter plate 9 to prevent them from clogging valve 2, ensuring the accuracy of the additive injection amount, and then using the stirring rod 6 to fully mix the inhibitor and solvent, dissolve the inhibitor crystals, and ensure the uniformity of the additive solution. When the butadiene transportation work is completed, the operator pulls up the safety cover 4, and the movement of the safety cover 4 drives the motor 5 to move up synchronously. The movement of the motor 5 drives the stirring rod 6 to move upward. When the stirring rod 6 moves upward, the compressed No. 1 spring 8 gradually recovers. After the No. 1 spring 8 is fully recovered, the stirring rod 6 continues to move to drive the lifting frame 7 to move upward, so that the rotating ring at the bottom is aligned with the additive The inner wall of the adding tank 3 is separated, and the contact friction between the rotating ring and the adding tank 3 is released. At the same time, the movement of the safety cover 4 drives the inserting plate 10 to move upward. The inserting plate 10 rubs against the deformed rubber sheet 12 until it is separated from the inner wall of the card plate 11. At this time, the deformed rubber sheet 12 recovers under the action of its own elasticity. After completing the removal of the safety cover 4, the operator can clean or repair the inside of the adding tank 3, the stirring rod 6 and the filter plate 9 to ensure that the mixing function is normal when used next time. By arranging the rubber sheet 12 in the card plate 11, it is ensured that the inserting plate 10 is closely fitted with the card plate 11, and moderate resistance can be provided when pulling to prevent the card plate 11 from accidentally loosening, thereby enhancing the stability of the work.

[0032] See also Figure 1 - Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, a protective device for improving sealing is provided on the circumferential surface of the adding tank 3, and a locking device for improving stability is provided on the protective device; the protective device includes a fixed frame 121, a telescopic rod 122, a No. 2 spring 123, a circular plate 124 and a sealing ring 125. The fixed frame 121 is fixedly installed on the circumferential surface of the adding tank 3, the telescopic rod 122 slides through the top of the fixed frame 121, the No. 2 spring 123 is arranged between the telescopic rod 122 and the fixed frame 121, the circular plate 124 is fixedly installed on the side of the telescopic rod 122 away from the No. 2 spring 123, and a sealing ring 125 is fixedly installed on the top of the circular plate 124. The sealing ring 125 contacts the circumferential surface of the adding tank 3 and contacts the bottom of the safety cover 4. When the sealing ring 125 moves up, the operator can clearly observe the status of the sealing ring 125 and determine whether it needs to be replaced.

[0033] A cylindrical rod 126 is fixedly installed on the circumferential surface of the telescopic rod 122, and a C-shaped plate 127 is fixedly installed on the top of the fixed frame 121. A sliding groove is provided on one side of the fixed frame 121 close to the cylindrical rod 126, and the cylindrical rod 126 is in contact with the sliding groove. Through the action of the reverse elastic force of the No. 2 spring 123, the sealing ring 125 and the safety cover 4 maintain a tight fit, which not only saves the time of installing the sealing ring 125 separately.

[0034] A circular groove is provided on the side of the cylindrical rod 126 away from the telescopic rod 122, and a friction groove is provided on the inner wall of the C-shaped plate 127. The circumferential surface of the cylindrical rod 126 contacts the friction groove, and the friction resistance between the cylindrical rod 126 and the C-shaped plate 127 is enhanced to ensure that the safety cover 4 can be smoothly fitted with the adding tank 3.

[0035] The locking device includes a connecting frame 131, a sliding plate 132, a linkage rod 133, a sliding rod 134, a control rod 135, two limit rods 136 and a hollow circular plate 137. The connecting frame 131 is fixedly mounted on the surface of the fixed frame 121, the sliding plate 132 is slidably mounted on the inner wall of the connecting frame 131, the linkage rod 133 is fixedly passed through the top of the sliding plate 132, the sliding rod 134 slides through the inner and outer walls of the connecting frame 131, and the control rod 135 is rotatably mounted on the sliding rod 134 away from the sliding On one side of the plate 132, two limit rods 136 are fixedly mounted on the circumferential surface of the control rod 135, and the hollow circular plate 137 is fixedly mounted on the side of the connecting frame 131 close to the limit rod 136. The shape of the top of the linkage rod 133 is set to be annular, and the inner wall of the linkage rod 133 contacts the circumferential surface of the cylindrical rod 126. The cylindrical rod 126 moves up synchronously through the sliding plate 132, effectively preventing the sliding rod 134 from moving forward due to misoperation and blocking the cylindrical rod 126, ensuring that the reset path of the cylindrical rod 126 remains unobstructed.

[0036] A torsion spring is provided between the control rod 135 and the sliding rod 134, and a rectangular groove is provided on the hollow circular plate 137. Through standardized operation, the operator can successfully complete the limiting of the cylindrical rod 126 only under the premise of ensuring safety, which effectively enhances the safety of operation.

[0037] When the present embodiment is working, when the operator lifts the safety cover 4, the pressure exerted by the safety cover 4 on the sealing ring 125 gradually decreases, and the compressed No. 2 spring 123 gradually recovers. The recovery of No. 2 spring 123 pushes the telescopic rod 122 to move upward, and the movement of the telescopic rod 122 drives the circular plate 124 and the cylindrical rod 126 to move upward, and the movement of the circular plate 124 drives the sealing ring 125 to move upward, and the sealing ring 125 exerts a continuous thrust on the bottom of the safety cover 4 during the movement until the sealing ring 125 is out of contact with the safety cover 4, and the cylindrical rod 126 moves upward and quickly separates from the friction groove, so that the friction between the cylindrical rod 126 and the C-shaped plate 127 is reduced. By applying additional thrust to the safety cover 4, the operator can smoothly remove the safety cover 4, and the sealing ring 125 moves upward. The operator can clearly observe the status of the sealing ring 125 and judge whether it needs to be replaced. When the operator installs the safety cover 4, its bottom first contacts the sealing ring 125. The top of the ring 125 contacts, causing the safety cover 4 to move and drive the sealing ring 125 to move downward, and the sealing ring 125 moves to drive the circular plate 124 to move downward, and the circular plate 124 moves to drive the telescopic rod 122 to move downward, and the telescopic rod 122 moves to squeeze the No. 2 spring 123, and the deformed No. 2 spring 123 exerts a reverse elastic force on the telescopic rod 122, and the reverse elastic force of the No. 2 spring 123 is transmitted to the sealing ring 125 through the telescopic rod 122, so that the sealing ring 125 forms a tight fit with the safety cover 4 under the action of the elastic force. At the same time, the telescopic rod 122 moves and drives the cylindrical rod 126 to move synchronously, and the cylindrical rod 126 moves and fully contacts the friction groove, and the friction resistance is increased together. The safety cover 4 is stably fitted with the adding tank 3 under the action of the friction resistance, and the sealing ring 125 is kept in close fit with the safety cover 4 through the reverse elastic force of the No. 2 spring 123, which not only saves the time of installing the sealing ring 125 separately, but also effectively reduces the risk of gas overflow.

[0038] When the cylindrical rod 126 moves up, the cylindrical rod 126 moves to drive the linkage rod 133 to move synchronously, and the linkage rod 133 moves to drive the sliding plate 132 to move up to the preset position. At this time, the operator manually rotates the control rod 135, and the control rod 135 rotates the tension torsion spring and drives the limit rod 136 to rotate. After the limit rod 136 rotates to the preset angle, the operator pushes the control rod 135 to move in the direction of the fixed frame 121, and the control rod 135 moves to drive the sliding rod 134 to move synchronously. At this time, the sliding plate 132 in place forms a physical barrier to prevent the sliding rod 134 from continuing to move, effectively preventing the sliding rod 134 from moving forward due to misoperation, and synchronizing the cylindrical rod 126 to move up by the sliding plate 132, effectively preventing the sliding rod 134 from moving forward due to misoperation to block the cylindrical rod 126, ensuring that the reset path of the cylindrical rod 126 remains unobstructed, and the cylindrical rod 126 When resetting downward, cylindrical rod 126 drives linkage rod 133 to reset downward, linkage rod 133 moves and drives sliding plate 132 to reset to its initial position. When sliding plate 132 stops moving, the operator repeats the above operation and pushes control rod 135 to move in the direction of fixed frame 121. Control rod 135 moves and drives limiting rod 136 and sliding rod 134 to move in the direction of fixed frame 121. Limiting rod 136 contacts the inner wall of the rectangular groove during movement, and sliding rod 134 contacts the circular groove of cylindrical rod 126 during movement, so that sliding rod 134 completes the limitation of cylindrical rod 126, ensuring that sealing ring 125 is stably fitted with adding tank 3 and safety cover 4 during transportation. Through standardized operation, the operator can successfully complete the limitation of cylindrical rod 126 only under the premise of ensuring safety, which effectively enhances the safety of operation.
