Description

TECHNICAL FIELD

[0001] The utility model belongs to tray technical field, concretely relates to a detachable tray structure for bubble cap column. BACKGROUND

[0002] In the chemical industry, petrochemical industry, fine chemical production and other industrial fields requiring efficient separation and reaction process, bubble cap column as an important gas-liquid contact equipment is widely used in distillation, absorption, desorption and extraction processes. The design and performance of bubble cap column are directly related to production efficiency, product quality and operating cost. Among them, the tray as the core component of the bubble cap column, its structural design and material selection have a crucial influence on the overall performance of the tower.

[0003] The traditional bubble cap tray structure often adopts fixed installation, which not only increases the difficulty of installation and maintenance, but also requires a large amount of manual labor cost when cleaning or replacing the tray, affecting the flexibility and efficiency of the production line. When multiple trays are stacked and installed, multiple bolts or fasteners are used for fixation, which is complicated and reduces the installation efficiency. In addition, the stability and bearing capacity of the stacked structure, to prevent structural damage or deformation due to weight and pressure concentration, are also important considerations in the design of bubble cap column. SUMMARY

[0004] The utility model aims at providing a detachable tray structure for bubble cap column to solve the installation, disassembly and bearing problems in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A detachable tray structure for bubble cap column, comprising a tray, a plurality of riser pipes are installed inside the tray, a bubble cap is detachably connected above the riser pipe, a overflow hole is formed on the surface of the tray, and a flow baffle is arranged on both sides of the tray inside; two or more trays are detachably stacked and installed;

[0007] Further, a plurality of positioning shafts are installed on the riser pipe, the bubble cap is installed above the riser pipe through the positioning shaft, and a connecting bolt is installed on the positioning shaft.

[0008] Further, reinforcing blocks are arranged at both ends of the bubble cap, a clamping groove is formed on the reinforcing block, and a rib is arranged at both ends of the riser pipe and matched with the clamping groove.

[0009] Further, the bottom of the tray is provided with a groove. When two or more trays are stacked, the bottom of the upper tray, i.e. the groove, cooperates with the top of the lower tray to complete the stacking process, ensuring the vertical alignment and close connection of the trays during the stacking process, effectively preventing horizontal or vertical displacement between the trays, thereby greatly enhancing the stability of the entire stacked structure.

[0010] Further, the tray is symmetrically provided with a support beam inside, and the bottom of the tray is symmetrically provided with a rib plate, which is perpendicular to the support beam.

[0011] Further, the tray is symmetrically provided with a sleeve inside, which is arranged close to the baffle, and a long bolt is installed inside the sleeve.

[0012] Further, the groove is filled with soft PVC pads. Soft PVC pads have good elasticity and buffering performance, which can effectively absorb and disperse the forces when the upper tray is subjected to pressure or impact, reducing direct collision and friction between the trays, thereby protecting the trays from damage.

[0013] Further, the bubble cap is in a rectangular structure. Under the same conditions, the strip-shaped (rectangular) bubble cap has a larger ventilation area than the circular bubble cap, which can save more area to reduce the tower diameter, thereby reducing the cost of enterprises.

[0014] The technical scheme of the utility model has the following beneficial effects:

[0015] 1. The bubble cap can be individually detached, which can reduce the labor cost during cleaning or replacement.

[0016] 2. When two or more trays are stacked, the bottom of the upper tray, i.e. the groove, cooperates with the top of the lower tray to complete the stacking process, and the rib plate at the bottom of the upper tray supports and contacts the support beam inside the lower tray, providing an additional support point for the stacked structure, effectively dispersing the weight and pressure generated during the stacking process, thereby significantly enhancing the load-bearing capacity and stability of the entire stacked structure.

[0017] 3. The long bolt is used to connect the trays together through the sleeve on the tray (to prevent axial deviation of the tray), further enhancing the stability and safety of the entire stacked structure. BRIEF DESCRIPTION OF DRAWINGS

This assembly method simplifies the stacking process of the tray 10, reduces the need for additional fixing devices or complex operation steps, making the assembly work more convenient and efficient, and improving work efficiency without the need for welding or other fasteners.

[0046] Embodiment three:

[0047] Reference Figure 11 The groove 23 is filled with a soft PVC pad 24.

[0048] In the above scheme, the soft PVC pad 24 has good elasticity and buffering performance, and when the upper tray is subjected to pressure or impact, the soft PVC pad 24 can effectively absorb and disperse these forces, reducing direct collision and friction between the trays 10, thereby protecting the trays 10 from damage. At the same time, it can reduce direct friction and collision between the trays 10 during installation.
