Description

Technical Field

[0001] The utility model relates to the technical field of trays, in particular to a tray connection device which is convenient for disassembly and assembly. Background Technique

[0002] The tray is one of the main components of the plate column. It is a component for heat transfer and mass transfer, and its role in the plate column is irreplaceable. In the plate column, the trays and plates need to be stacked layer by layer to complete the work requirements. A large number of trays are distributed on each plate, but a large amount of scale will adhere to the surface of the trays during the working process in the plate column, and it is necessary to disassemble them for cleaning.

[0003] The existing trays are stacked layer by layer on the plate column. Usually, three positioning holes distributed in a triangle are formed on the trays, and three inserting rods distributed in a triangle are arranged on the plate column. The trays are fixed on the plate column by inserting the positioning holes into the inserting rods. However, in this fixing method, when the trays are affected by thermal expansion and contraction and the impact of water flow during the working process, and the trays generate slight deformation, the three positioning holes on the trays are three fixing points, resulting in mutual pulling of the three fixing points on the trays. Therefore, the three positioning holes on the trays are easily stuck on the inserting rods on the plate column, making it difficult to remove the trays from the plate column. For this reason, we propose a tray connection device which is convenient for disassembly and assembly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tray connection device which is convenient for disassembly and assembly to solve the above deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A tray connection device which is convenient for disassembly and assembly, including a main body of the plate column. Inside the main body of the plate column, tray bodies are arranged at equal distances. In the central position of the top of the tray body, a positioning tube is fixedly arranged. The inner walls of both ends of the positioning tube are inserted with sliding rods. Limiting rings are fixedly arranged on the outer walls of the two sliding rods. Compression springs are sleeved on the outer walls of the adjacent ends of the two sliding rods. At one end of the top of the two sliding rods, fixing rods are fixedly arranged. At one end of the top of the two fixing rods, a pull rod is fixedly arranged. A sliding groove is formed on the outer wall of the top of the positioning tube. The outer wall of the sliding groove is slidably connected with the inner wall of the fixing rod. A limiting hole is formed on one side of the top of the tray body. A fixing block is fixedly arranged on the inner wall of one side of the bottom of the main body of the plate column. A vertically upward limiting inserting rod is fixedly arranged on the outer wall of the fixing block. The outer wall of the limiting inserting rod is slidably connected with the inner wall of the limiting hole. Positioning tubes are fixedly arranged at equal distances on the outer walls of both sides of the main body of the plate column through openings. The outer wall of one end of the sliding rod is adapted to the inner wall of the positioning tube.

[0007] Preferably, a matching upper cover body is provided on the outer wall of the top of the plate column body, and a matching lower cover body is provided on the outer wall of the bottom of the plate column body.

[0008] Preferably, a first docking ring is fixedly arranged between the outer wall of the bottom of the upper cover body and the outer wall of the top of the lower cover body. Second docking rings are fixedly arranged on the outer walls of the top and bottom of the plate column body. Fixing holes are arranged at equal distances on the outer walls of the first docking ring and the second docking ring. Bolts matching the inner walls of the fixing holes are provided, which is convenient for fixing the upper cover body and the lower cover body to the top and bottom of the plate column body.

[0009] Preferably, a water inlet pipe is fixedly arranged at one side of the top of the plate column body through an opening, and a drain pipe is fixedly arranged at one end of the bottom of the lower cover body through an opening. The water to be cooled is discharged into the plate column body through the water inlet pipe, and the cooled water is discharged through the drain pipe.

[0010] Preferably, an air inlet pipe is fixedly arranged at one side of the bottom of the plate column body through an opening, and an exhaust pipe is fixedly arranged at one end of the top of the upper cover body through an opening.
