Description

Technical Field

[0001] This utility model relates to the field of resin reaction vessel technology, and more specifically, to a novel reaction vessel for the production of unsaturated polyester resin. Background Technology

[0002] In the production of unsaturated polyester resin, multiple samples need to be taken from the reactor to monitor the reaction progress and product quality indicators. Traditional sampling methods typically involve opening the reactor's manhole, handhole, or sampling valve at the bottom, followed by external testing. This method is prone to causing burns from high temperatures and disrupts the reaction balance within the reactor, affecting product quality. Another sampling method uses a sampling tube to extract the high-temperature resin from the reactor.

[0003] However, the above methods can only sample resin from fixed locations, making it difficult to sample resin from different sections of the reactor. Resin at different heights will vary due to differences in the degree of agitation, which will affect the final accuracy of the sampling and testing.

[0004] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

[0028] A rotating ring 19 is fixedly connected to the side of the collar 13 near the moving pipe 4. A guide rail is provided on the moving pipe 4 for the rotating ring 19 to be inserted and moved. The cross-sections of the rotating ring 19 and the guide rail are both trapezoidal. A slot 6 is provided in the guide rod 3 for the insertion tube 5 to pass through. An opening and closing plate 7 is provided at the end of the guide rod 3 away from the insertion tube 5. A transfer hose 8 is connected to the end of the moving pipe 4 away from the vessel body 1. The other end of the transfer hose 8 is connected to the vacuum pump.

A vacuum valve is connected between the transfer hose and the vacuum pump. The middle section of the transfer hose 8 is also connected to a storage chamber for convenient storage of extracted resin samples.

[0029] A protrusion is fixedly connected to one end of the guide rod 3 near the opening and closing plate 7. A rotating block 14 is provided on the inner wall of the protrusion and is rotatably connected to it via a rotating shaft. A torsion spring 15 is sleeved on the outer wall of the rotating shaft. The two ends of the torsion spring 15 are fixedly connected to the side walls of the protrusion and the rotating block 14, respectively. The opening and closing plate 7 is fixedly connected to the rotating block 14. When the torsion spring 15 is in the initial state, the opening and closing plate 7 will cover the slot opening of the slot 6.

[0030] A limiting block 17 is fixedly connected to the outer wall of the end of the insertion tube 5 away from the vessel body 1. A limiting groove 18 is provided on the inner wall of the moving pipe 4 for the limiting block 17 to be inserted and moved. During the movement of the insertion tube 5, the limiting block 17 will be inserted into the limiting groove 18 to move, so that the insertion tube 5 can be more stable during the movement.

[0031] Working principle: When resin samples need to be taken from different points inside the vessel 1, the motor 11 first drives the lead screw 10 to rotate. The forward and reverse rotation of the lead screw 10 drives the nut seat 12 to rise and fall along the lead screw 10. The nut seat 12 then drives the moving pipe 4 to rise and fall, moving the moving pipe 4 to correspond to any of the mounting sleeves 2 positions. The motor 11 is then turned off, allowing the moving pipe 4 to stop at the current height. Then, the collar 13 is held and rotated. Since the insertion tube 5 and the collar 13 are connected by a threaded fit, the rotation of the collar 13 drives the insertion tube 5 to move, causing the insertion tube 5 to extend out of the moving pipe 4 and insert into the slot 6 of the inlet rod 3. When the insertion tube 5 penetrates the inlet rod 3, the opening and closing plate 7 is pushed open by the insertion tube 5. At this time, the torsion spring 15 will deform due to the rotation of the opening and closing plate 7 and the rotating block 14. The opening and closing plate 7 will rotate to a horizontal state, contacting the side wall of the insertion tube 5, allowing the insertion tube 5 to smoothly extend into the vessel 1. The vacuum pump then... The resin is extracted through the transfer hose 8 and the insertion tube 5 from the vessel body 1. After the sample quantity is reached, the collar 13 is held and rotated in the opposite direction to retract the insertion tube 5 into the moving pipe 4. The insertion tube 5 will then be gradually pulled out of the slot 6. After the insertion tube 5 is removed, the opening and closing plate 7 can return to its original position through the elastic rebound force of the torsion spring 15, and close again to cover the slot opening of the slot 6, preventing resin leakage from the vessel body 1 and completing the sampling. In this way, the resin at different heights can be sampled by lifting and lowering the moving pipe 4. By inserting the insertion tube 5 to different depths, resin at different points at the same height can be sampled, making the sampling more comprehensive and sufficient, and fully connecting the reaction status of the resin at different positions. At the same time, during the sampling process, the heating wire 16 can heat the resin in the insertion tube 5 to maintain a high temperature throughout the sampling process, reducing the occurrence of blockage during the sampling process.
