Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to an automatic safety alarm device for distillation towers. Background Art

[0002] Distillation towers are commonly used equipment in chemical production. The temperature, pressure, liquid level and other parameters during their operation are crucial to production safety. Traditional safety alarm devices often rely on manual inspections and fixed threshold judgments, and have problems such as slow response speed and high false alarm rate.

[0003] The existing patent document with publication number CN210905032U discloses a rapidly controllable distillation automatic control device, comprising a distillation tower, both sides of the top of the distillation tower and both sides of the inner wall of the distillation tower are fixedly connected with automatic control detection mechanisms, the middle of the top of the distillation tower is fixedly connected with a connecting pipe, the bottom of the right side of the distillation tower is fixedly connected with a display, and the four automatic control detection mechanisms are electrically connected to the display through wires respectively.

[0004] When the above equipment is used, the following problems exist:

[0005] (1) The data inside the distillation tower is generally monitored and transmitted through corresponding sensors. However, due to the limitation of the internal space of the distillation tower, the installation, debugging and maintenance of the sensors are relatively cumbersome.

[0006] (2) Due to space limitations, existing sensors can generally only be installed on the side walls of distillation towers. However, the temperature at the side wall may not fully represent the actual temperature of the material in the tower, especially in the area close to the tower wall where there may be a temperature gradient or heat loss. The temperature detected at the center may be closer to the mainstream area of ​​the material in the tower. The side wall installation method cannot well reflect the overall temperature changes.

[0007] Therefore, we propose an automated safety alarm device for distillation towers to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figures 1 to 6 The distillation tower automatic safety alarm device comprises a distillation tower 1 and a fixing rod 9. The distillation tower 1 is evenly and evenly fixed with mounting barrels 2. The mounting barrels 2 are connected to the inside of the distillation tower 1. The monitoring device can be installed through the mounting barrels 2. The design of multiple mounting barrels 2 at different heights allows the distillation tower 1 to be covered at different heights.

[0032] A connecting rod 4 is slidably mounted on the fixing rod 9, and an internal thread cover 5 is rotatably mounted on one end of the connecting rod 4 away from the fixing rod 9;

[0033] A mounting plate 10 is fixedly mounted on one end of the fixing rod 9 away from the connecting rod 4, and a sensor 11 is arranged on the mounting plate 10;

[0034] By making the fixing rod 9 and most of the connecting rods 4 inside the distillation tower 1, the placement of the sensor 11 is realized, and the length of the whole formed by the fixing rod 9 and the connecting rod 4 can be adjusted, thereby changing the placement position of the sensor 11 on the plane.

[0035] An external thread groove 3 is provided on the side of the installation cylinder 2 facing away from the distillation tower 1 , and an internal thread cover 5 is matched with the external thread groove 3 .

[0036] By making the internal thread cover 5 contact with the external thread groove 3 and then rotating the internal thread cover 5, the installation tube 2 can be initially sealed.

[0037] Two fixing columns 14 are fixedly installed on one end of the connecting rod 4 close to the fixing rod 9, and a locking rod 13 is slidably installed on the fixing column 14. A spring 15 is fixedly installed on the locking rod 13, and the other end of the spring 15 is fixedly installed on the connecting rod 4. By pressing the locking rod 13, the locking rod 13 can be moved on the fixing column 14 under the action of the spring 15, so that only a small part of the locking rod 13 can be exposed, which is convenient for moving the connecting rod 4.

[0038] Positioning holes 12 adapted to the engaging rods 13 are evenly and equidistantly formed on the fixing rod 9 .

[0039] By placing the engaging rods 13 on different positioning holes 12 , the overall length adjustment effect of the fixing rod 9 and the connecting rod 4 can be achieved.

[0040] Two slide grooves 16 are provided inside the fixing rod 9 for the locking rod 13 to slide, and rotation grooves 17 are evenly and equidistantly provided inside the fixing rod 9. Two rotation grooves 17 in the same plane constitute a group. The two rotation grooves 17 in a group are respectively connected to the upper and lower slide grooves 16, and the positioning hole 12 is located at the end of the corresponding rotation groove 17.

[0041] The two engaging rods 13 are both located inside the slide groove 16. At this time, the connecting rod 4 can be moved. When it moves to the required position, the two engaging rods 13 correspond to the entrances of two rotating grooves 17 in one group. Then, the connecting rod 4 is rotated, and the engaging rod 13 can move on the rotating groove 17. When the engaging rod 13 moves to the end of the rotating groove 17, due to the presence of the positioning hole 12, the engaging rod 13 is not blocked. Under the action of the spring 15, the engaging rod 13 will be exposed from the positioning hole 12, thereby ensuring the stability of the overall length of the fixing rod 9 and the connecting rod 4.

[0042] When the overall length of the fixing rod 9 and the connecting rod 4 needs to be adjusted, it is only necessary to press the locking rod 13 to disengage the locking rod 13 from the positioning hole 12, and then rotate the connecting rod 4 so that the locking rod 13 can move on the rotating groove 17, and then return to the sliding groove 16, and the connecting rod 4 can move.

[0043] The diameter of the mounting plate 10 is smaller than the diameter of the inner circle of the mounting tube 2 , so the mounting plate 10 can be smoothly placed through the mounting tube 2 .

[0044] A fixing plate 7 is fixedly mounted on the connecting rod 4, and a rubber ring 8 is inlaid on the fixing plate 7. The rubber ring 8 is divided into two parts. The part close to the installation tube 2 is frustum-shaped, and the other part is cylindrical. The rubber ring 8 and the inner wall of the installation tube 2 are in interference fit.

[0045] The existence of the rubber ring 8 can prevent the fluid from leaking through the installation tube 2, thereby ensuring the normal operation of the equipment.

[0046] The fixing rod 9 and the connecting rod 4 are both hollow structures. A signal transmission line 6 is disposed inside the fixing rod 9 and the connecting rod 4 , and one end of the signal transmission line 6 is connected to the sensor 11 .

[0047] The signal transmission line 6 is located inside the fixing rod 9 and the connecting rod 4, and the joint of the signal transmission line 6 can be located inside the mounting plate 10, which can avoid direct contact with the liquid, thereby ensuring the stability of the equipment operation.

[0048] The working process of the utility model; firstly, the overall length of the fixing rod 9 and the connecting rod 4 is adjusted according to the actual needs, and the connecting rod 4 can be moved through the cooperation of the locking rod 13 and the sliding groove 16. At this time, the overall length of the fixing rod 9 and the connecting rod 4 is changed.

[0049] When it moves to the corresponding point, at this time, the two engaging rods 13 correspond to the entrances of two rotating grooves 17 in a group, and then the connecting rod 4 is rotated, and the engaging rod 13 can move on the rotating groove 17. When the engaging rod 13 moves to the end of the rotating groove 17, due to the existence of the positioning hole 12, the engaging rod 13 is not blocked. Under the action of the spring 15, the engaging rod 13 will be exposed from the positioning hole 12, thereby ensuring the stability of the overall length of the fixing rod 9 and the connecting rod 4.

[0050] Then, the installation tube 2 is placed, and the fixing rod 9 and most of the connecting rods 4 are placed inside the distillation tower 1. At this time, the sensor 11 is in the required position. When placing, the rubber ring 8 is interference fit with the inner wall of the installation tube 2 to prevent fluid from leaking through the installation tube 2. The internal thread cover 5 is in contact with the external thread groove 3. Then, the internal thread cover 5 is rotated to make the installation tube 2 closed.

[0051] Afterwards, the information of the sensor 11 can be transmitted through the signal transmission line 6, thereby realizing the safety alarm function.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
