Description

Technical Field

[0001] The present invention relates to the technical field of storage tanks, and more specifically, to an intermediate storage tank for a green and environmentally friendly polymerization inhibitor. Background Art

[0002] The intermediates of green environmentally friendly inhibitors have high reactivity and are prone to react with oxygen, moisture or other impurities in the air, resulting in deterioration or failure. Storage tanks can provide a relatively closed and stable environment to reduce the impact of these adverse factors. Secondly, storage tanks are made of high-strength, corrosion-resistant materials with good sealing properties, which can effectively prevent leakage of intermediates. This can not only protect the production environment from pollution, but also avoid safety accidents such as fire and explosion caused by leakage.

[0003] In the existing public documents, the patent with patent announcement number CN210437640U discloses a polymerization inhibitor storage tank, which is mainly fixedly connected to a cylinder through the lower end of a second connecting rod, and sliders are fixedly connected to the left and right sides of the cylinder. The front and rear sides of the cylinder are provided with openings, and a disc is fixedly connected to the lower surface of the cylinder. The polymerization inhibitor storage tank has the characteristics of easy discharge and convenient use. However, the storage tank still has the following defects when in use;

[0004] When a storage tank is used to store and use green and environmentally friendly polymerization inhibitor intermediates, it is necessary to achieve sealed storage through multiple pipes and tanks. However, it is difficult to detect the sealing of each pipe and tank during storage, which makes it difficult to promptly know if there is a leak in the pipe or tank. If maintenance is not timely and the leak cannot be detected, the green and environmentally friendly polymerization inhibitor intermediates will be easily deteriorated and damaged after storage. Therefore, an intermediate storage tank for green and environmentally friendly polymerization inhibitors is needed. Summary of the invention

[0008] Preferably, the connecting pipe is threadedly connected and communicated with the sealing valve, the connecting pipe and the connecting branch pipe are both made of stainless steel, the output end of the negative pressure pump is threadedly connected with a locking valve, and one end of the locking valve is fixedly installed with a communicating external pipe, and the external pipe is made of stainless steel, a plurality of protective frames are welded to one side of the outer wall of the intermediate tank body, and the plurality of protective frames are arranged equidistantly from top to bottom; a climbing frame is fixedly connected to the inner wall of the protective frame, and a controller is fixedly installed on one side of the outer wall of one of the protective frames, a plurality of brackets are fixedly connected to the top of the intermediate tank body and close to its edge line, and a support ring rod is connected to the top of the bracket; the plurality of brackets are fixedly connected to the support ring rod, a tank valve is installed at the bottom end of the outer wall of the collecting pipe, and the collecting pipe and the intermediate tank body are fixedly connected to the tank valve.

[0009] When this technology is used, the controller starts the negative pressure pump to open the locking valve. The negative pressure pump generates negative pressure in the suction pipe, opens the tank valve, opens the test valve and the liquid inlet valve, and closes the sealing valve. The test valve enters the connecting branch pipe, and the negative pressure air enters the suction pipe along the collecting pipe to realize external extraction, and the external discharge pipe realizes external discharge. The liquid inlet valve is closed to realize negative pressure sealing operation on the connecting pipe. Secondly, the tank valve can draw the negative pressure air inside the intermediate tank into the collecting pipe, which is transported to the locking valve through the suction pipe by the collecting pipe, and the tank valve is closed.

If there is a leakage problem, it is immediately repaired and the leakage problem is timely known to avoid the green and environmentally friendly inhibitor intermediate being easily deteriorated and damaged after storage.

[0016] The present invention uses a middle sealing detection mechanism to close the upper valve, open the side pipe valve, and close the lower valve. Negative pressure air enters the collecting pipe along the test side pipe. After the negative pressure reaches a specified value, the side pipe valve is closed and the side pipe valve is opened. In this way, the feed branch pipe is connected with the collecting pipe through the test side pipe. The sealing state of the feed branch pipe can be detected, and the air leakage problem is known in time, which avoids the green and environmentally friendly inhibitor intermediate from being easily deteriorated and damaged after being stored.

[0017] The present invention adopts a bottom sealing detection component, opens the detection valve and closes the sealing valve and the sealing valve, and the sealing valve can seal the passage between the detection bottom pipe and the connecting pipe.

The detection bottom pipe can be sealed and the leakage problem can be known in time.

[0018] The interaction of the above multiple functions firstly knows whether the connecting pipe and the intermediate tank are leaking, then the sealing state of the feed branch pipe can be tested, and finally the bottom pipe can be tested for sealing.

[0034] In this technical solution, as shown in the attached Figure 6-8 As shown, the bottom sealing detection assembly includes a detection valve 25 arranged below the test side pipe 20; one end of the detection valve 25 is fixedly connected to the collecting pipe 7, and the other end of the detection valve 25 is threadedly connected to a connecting branch pipe 26, and one end of the connecting branch pipe 26 is welded to a detection bottom pipe 27; one end of the detection bottom pipe 27 is threadedly connected to a sealing valve 28, and a butt pipe 29 is fixedly connected between the sealing valve 28 and the intermediate tank body 1, and one end of the detection bottom pipe 27 is threadedly connected to a sealing valve 30, and one end of the sealing valve 30 is welded to a connected connecting pipe 31. The sealing valve 30 and the sealing valve 28 are symmetrically arranged about the detection bottom pipe 27, and the detection bottom pipe 27 is made of stainless steel.

[0035] The working principle of the intermediate storage tank for green and environmentally friendly polymerization inhibitor of the present invention is as follows:

[0036] Step 1, when the top is sealed, the controller 16 starts the negative pressure pump 11 to open the locking valve 12, and the negative pressure pump 11 generates negative pressure in the suction pipe 10, and opens the tank valve 19 at the same time, and opens the test valve 5 and the liquid inlet valve 2, and closes the sealing valve 4, so that the negative pressure of the air inside the connecting pipe 3 is drawn into the test valve 5, and enters the connecting branch pipe 6 through the test valve 5, and enters the collecting pipe 7 through the connecting branch pipe 6, and the negative pressure air enters the suction pipe 10 along the collecting pipe 7 to realize external extraction, and the suction pipe 10 enters the external discharge pipe 13 along the locking valve 12, and the external discharge pipe 13 realizes external discharge, and immediately closes the liquid inlet valve 2 to realize negative pressure sealing operation on the connecting pipe 3. Secondly, the tank valve 19 can draw the negative pressure air inside the intermediate tank body 1 into the collecting pipe 7, and the collecting pipe 7 is transported to the locking valve 12 through the suction pipe 10, and then the locking valve 12 is discharged through the external discharge pipe 13, and the tank valve 19 is closed after the negative pressure inside the suction pipe 10 is completed.

[0037] Step 2, when the middle is sealed, the upper valve 23 is closed and the side pipe valve 21 is opened, and the lower valve 24 is closed and blocked at the same time. In this way, the negative pressure air inside the feed branch pipe 22 enters the side pipe valve 21, and the negative pressure enters the test side pipe 20 through the air side pipe valve 21. The negative pressure air enters the collecting pipe 7 along the test side pipe 20, and enters the suction pipe 10 through the collecting pipe 7. The suction pipe 10 is discharged from the external exhaust pipe 13 through the locking valve 12. After the negative pressure reaches the specified value, the side pipe valve 21 is closed to realize the negative pressure sealing operation of the feed branch pipe 22.

[0038] Step 3: When the bottom is sealed, open the detection valve 25 and close the sealing valve 30 and the sealing valve 28 at the same time. The sealing valve 30 can block the passage between the detection bottom pipe 27 and the connecting pipe 31, and the sealing valve 28 can block the butt joint pipe 29. The negative pressure air inside the detection bottom pipe 27 flows along the connecting branch pipe 26, and the negative pressure air enters the detection valve 25 along the connecting branch pipe 26, enters the collection pipe 7 through the detection valve 25, enters the suction pipe 10 along the collection pipe 7, and realizes the upper discharge operation through the outer discharge pipe 13 along the locking valve 12. After the detection bottom pipe 27 is negatively pressurized, the detection valve 25 can be closed to achieve negative pressure blocking of the detection bottom pipe 27. Then close the locking valve 12 and the negative pressure pump 11.

[0039] Step 4: When checking the sealing status of the intermediate tank body 1, the tank body valve 19 can be opened. When the intermediate tank body 1 and the collecting pipe 7 are connected through the tank body valve 19, and the pressure sensor 9 can detect the negative pressure of the collecting pipe 7 through the delivery pipe 8, when the pressure value of the pressure sensor 9 does not fluctuate, the sealing status of the intermediate tank body 1 is normal. When the negative pressure data of the pressure sensor 9 fluctuates beyond the standard, there is a problem with the sealing of the intermediate tank body 1, and the intermediate tank body 1 can be repaired. When testing the connecting pipe 3, open the test valve 5, so that the negative pressure air inside the connecting pipe 3 is connected to the collecting pipe 7 through the connecting branch pipe 6, so that the pressure sensor 9 can sense the negative pressure air of the collecting pipe 7 through the delivery pipe 8. If the pressure does not fluctuate, the sealing of the connecting pipe 3 is normal. When the pressure exceeds the pressure fluctuation range set by the controller 16, it is known that there is a problem with the sealing status of the connecting pipe 3 and timely repair is carried out.

[0040] Then open the side pipe valve 21 so that the feed branch pipe 22 is connected to the manifold 7 through the test side pipe 20, so that the pressure sensor 9 realizes negative pressure detection on the manifold 7 through the delivery pipe 8. When the pressure exceeds the fluctuation range, there is a problem with the sealing of the feed branch pipe 22. When there is no fluctuation, the feed branch pipe 22 is normal. Then open the detection valve 25, so that the detection bottom pipe 27 is connected to the manifold 7 through the connecting branch pipe 26 and the detection valve 25, and the pressure sensor 9 is connected to the manifold 7 through the delivery pipe 8 for testing. When the pressure sensor 9 sensing data fluctuates beyond the setting range of the controller 16, the detection bottom pipe 27 has a leakage problem. When the controller 16 does not fluctuate, it is known that the detection bottom pipe 27 is not leaking. Then open the tank valve 19, the intermediate tank 1 is connected to the manifold 7 through the tank valve 19, so that the pressure sensor 9 realizes testing on the manifold 7 through the delivery pipe 8. When the pressure sensor 9 has pressure fluctuations, it can be known that the intermediate tank 1 has a sealing leakage. If there is no fluctuation, the intermediate tank 1 is sealed normally.

[0041] Step 5: During storage and protection, the support ring rod 18 can be supported by multiple brackets 17, so that the multiple brackets 17 increase the stability above the intermediate tank body 1. When maintenance personnel perform maintenance, they can climb up through the climbing frame 15, and the multiple protection frames 14 can protect the maintenance personnel. When storing, close the test valve 5, open the sealing valve 4 and the liquid inlet valve 2, and let the green environmentally friendly inhibitor intermediate enter the connecting pipe 3 through the sealing valve 4, and then enter the intermediate tank body 1 through the connecting pipe 3 along the liquid inlet valve 2 for storage.
