Description

[Technical field]

[0001] The utility model relates to the field of towers, in particular to a tool for detecting the horizontality of a tower plate support ring. [Background technology]

[0002] The tower is a process equipment with a cylindrical welded structure, which consists of a cylinder, a head (or cover) and a support. It is a non-standard equipment designed and manufactured specifically for a certain production process requirement. The tower is an upright equipment used for chemical unit operations such as distillation, purification, absorption, and rectification, and is widely used for mass transfer and heat transfer between gas-liquid and liquid-liquid phases. The tower is divided into two categories according to its structure: plate tower and packed tower. A certain number of trays are provided in the plate tower, and the gas contacts the liquid layer on the tray in the form of bubbling or spraying for material transfer. The horizontality of the tray affects the horizontality of the liquid layer on the tray. Otherwise, the tray is tilted, the thickness of the liquid layer is uneven, and the gas phase cannot pass through the liquid layer evenly, resulting in low mass transfer efficiency. In order to support several tower plates in the cylinder, several parallel tower plate support rings are usually welded on the inner wall of the cylinder, and the horizontality of the tower plate support ring will directly determine the horizontality of the tower plate. We found in daily work that the tower plate support ring is often welded obliquely, so that its horizontality cannot be guaranteed. In the prior art, workers usually measure along the section between two tower plate support rings with a ruler to judge its horizontality. We found that this detection method has low detection efficiency.

[0003] Therefore, it is necessary to provide a tower plate support ring horizontality detection tool that solves the above technical problems. [Utility Model Content]

[Specific implementation method]

[0022] The following is a further detailed description of a tower plate support ring horizontality detection tooling of the utility model through specific embodiments.

[0023] Ginseng Figures 1 to 5As shown, a tool for detecting the horizontality of a tower plate support ring comprises: a first arc plate 1 and a second arc plate 2 arranged in parallel with the first arc plate 1. The reason why the utility model designs the first arc plate 1 and the second arc plate 2 as an arc structure instead of a straight plate structure is mainly based on the following considerations: since the barrel of the tower is a cylinder, when the detection tool moves between two adjacent tower plate support rings, the shapes of the first arc plate 1 and the second arc plate 2 can just match the cylinder, thereby reducing the interference between the two. The first arc plate 1 is provided with at least two first pulleys 3, and the second arc plate 2 is provided with at least two second pulleys 4. In this embodiment, the number of the first pulleys 3 is two, and the number of the second pulleys 4 is also two. The first pulley 3 is installed on the inner side of the first arc plate 1 through the first fixing member 5, and the second pulley 4 is installed on the inner side of the second arc plate 2 through the second fixing member 6. The first pulley 3 and the second pulley 4 are arranged opposite to each other. In this embodiment, the first fixing member 5 and the second fixing member 6 are both hexagonal studs.

[0024] At least one spacing adjustment mechanism 7 is provided between the first curved plate 1 and the second curved plate 2. In this embodiment, the number of the spacing adjustment mechanisms 7 is three, and each spacing adjustment mechanism 7 includes: a first threaded seat 70 welded to the inner side of the first curved plate 1, a first stud 71 installed in the first threaded seat 70, a second threaded seat 72 welded to the inner side of the second curved plate 2, a second stud 73 installed in the second threaded seat 72, and an adjustment rod 74 for connecting the first stud 71 and the second stud 73. The adjustment rod 74 is hollow and provided with a pry bar through hole 740. When working, the pry bar is inserted into the pry bar through hole 740 of the adjustment rod 74 to drive the adjustment rod 74 to rotate. The diameter of the adjustment rod 74 is greater than 20 mm, so as to ensure that it has sufficient structural strength. When the adjusting rod 74 is in the state of being rotated, the first screw thread 741 of the locking lever 74 is locked and the locking lever 74 is locked. In this embodiment, the first arc plate 1, the second arc plate 2 and the spacing adjustment mechanism 7 are all made of alloy steel, and thus have high structural strength.

[0025] The working principle of the tower tray support ring level detection tooling in the utility model is as follows: during detection, the detection tooling in the utility model is placed between the two tower tray support rings, so that the pulley of the detection device is supported on the inner wall of the cylinder between the two tower tray support rings, and then the crowbar is inserted into the crowbar through hole 740 of the adjustment rod 74, and then the crowbar is rotated to drive the adjustment rod 74 to rotate, and the rotation of the adjustment rod 74 drives the first stud 71 and the second stud 73 to extend outward synchronously and finally makes the first arc plate 1 and one of the tower tray support rings The side walls of the rings are abutted against each other, so that the second arc plate 2 is abutted against the side wall of another tower plate support ring, and then the detection device is slid back and forth along the circumference of the tower plate support ring. If the detection tooling can pass through the entire circumference of the tower plate support ring relatively smoothly, it means that the horizontality of the two adjacent tower plate support rings meets the design requirements, and then the next group is detected. If the detection tooling is stuck when passing through the circumference of the tower plate support ring, it means that the horizontality of the two adjacent tower plate support rings cannot meet the design requirements and needs to be repaired.

[0026] To sum up, the tower plate support ring horizontality detection tooling in the utility model has a simple structure and is easy to install. By setting an adjusting rod, the distance between the first arc plate 1 and the second arc plate 2 can be adjusted, so that it can be suitable for detecting towers of different specifications. By using the detection tooling in the utility model to detect the horizontality of the tower plate support ring, the detection efficiency can be greatly improved.

[0027] The above-mentioned embodiments are only illustrative of the principles and effects of the invention of the utility model, as well as some embodiments of its application, and are not intended to limit the invention of the utility model. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and these all fall within the scope of protection of the invention.
