Description

Technical Field

[0001] The utility model relates to the technical field of floating valve tower trays, in particular to a guiding floating valve tower tray for a packing tower. Background Art

[0002] The guide float valve tray for packed tower is a place for gas-liquid two-phase mass transfer and heat transfer. A valve hole of a certain shape (circular or rectangular) is opened on the plate, and a valve plate that can float up and down is installed in the hole. There are circular, rectangular, disc-shaped, etc., thus forming different types of float valve trays. However, during the operation of the existing float valve tray, the float valve is easily stuck, rusted or stuck, and cannot be opened freely. When the tray is overhauled, the rusted float valve must be replaced, and the practicability of the device is poor.

[0003] In this solution, a guide floating valve tray for a packed tower is therefore needed to improve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to provide a guide float valve tray for a packed tower to solve the problems raised in the above background technology.

[0007] The float valve assembly includes a slide rod, which is slidably connected to the inner wall of the mounting hole, a fixed shell is installed at one end of the slide rod, a fixed column is installed on the inner wall of the fixed shell, an upper cover is installed on the outer wall of the fixed column, and a bottom plate is installed at the other end of the slide rod.

[0008] As a preferred solution of the utility model, the mounting holes are provided in multiple groups and are respectively located on the outer wall of the tower plate, and the float valve assemblies are provided in multiple groups and are respectively located on the inner walls of the mounting holes.

[0009] As a preferred solution of the utility model, the guide blocks are provided in multiple groups and are respectively located on the outer wall of the tower plate, and the slide bars are provided in multiple groups and are respectively located on the inner wall of the mounting hole.

[0010] As a preferred solution of the utility model, the fixed shell is an arc-shaped structure, and the fixed shell is provided with multiple groups and respectively located on the outer wall of the sliding rod.

[0011] As a preferred solution of the utility model, the fixed shell is located directly above the mounting hole, and the fixed columns are provided in multiple groups and are respectively located on the inner wall of the fixed shell.

[0012] As a preferred solution of the utility model, the upper cover is located directly above the mounting hole, the upper cover is an arc-shaped structure, and the bottom plate is located on one side of the guide block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a float valve assembly in a guide float valve tray of a packed tower is used, and a slide rod in the float valve assembly is used to be located in the inner cavity of the mounting hole, so that the upper cover is covered on the mounting hole for sealing. When there is high-pressure gas under the tray, the gas rushes into the mounting hole through the gap between the bottom plate and the slide rod, and the upper cover is lifted to open the float valve. Conversely, the bottom plate pulls the slide rod downward under the action of gravity, driving the float valve to close. The device has better practicality. Compared with the traditional float valve with long sheet legs, the contact area between the slide rod and the inner wall of the mounting hole is smaller. The float valve assembly is stuck at the port of the mounting hole through the fixed shell of the arc structure, and the stability of the device is also guaranteed. There is no need to worry about the float valve being easily stuck, rusted or stuck, which is beneficial to solving the problem that the float valve is easily stuck, rusted or stuck during the operation of the existing float valve tray and cannot be opened freely. The rusted float valve must be replaced during the maintenance of the tray, and the practicality of the device is poor. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] A guide float valve tray for a packed tower comprises a tray 1, a mounting hole 2 is provided on the outer wall of the tray 1, a float valve assembly 3 is provided on the inner wall of the mounting hole 2, and a guide block 4 is provided on one side of the mounting hole 2 and on the outer wall of the tray 1;

[0022] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The float valve assembly 3 includes a slide rod 301, which is slidably connected to the inner wall of the mounting hole 2. The slide rod 301 is provided with multiple groups and are respectively located on the inner wall of the mounting hole 2. A fixed shell 302 is installed at one end of the slide rod 301. The fixed shell 302 is an arc-shaped structure. The fixed shell 302 is provided with multiple groups and are respectively located on the outer wall of the slide rod 301. The fixed shell 302 is located directly above the mounting hole 2. A fixed column 303 is installed on the inner wall of the fixed shell 302. The fixed column 303 is provided with multiple groups and are respectively located on the inner wall of the fixed shell 302. An upper cover 304 is installed on the outer wall of the fixed column 303. The upper cover 304 is located directly above the mounting hole 2. The upper cover 304 is an arc-shaped structure. A bottom plate 305 is installed at the other end of the slide rod 301. The bottom plate 305 is located on one side of the guide block 4.

[0023] Furthermore, the mounting holes 2 are provided in multiple groups and are respectively located on the outer wall of the tower plate 1, the float valve assemblies 3 are provided in multiple groups and are respectively located on the inner wall of the mounting holes 2, and the guide blocks 4 are provided in multiple groups and are respectively located on the outer wall of the tower plate 1. The guide blocks 4 play a role in guiding and gathering the airflow, so that the airflow can more easily enter the inner cavity of the mounting holes 2.

[0024] The working process of the utility model is as follows: when the guide float valve tray for the packed tower designed by the present invention is working, the slide bar 301 is slidably connected to the inner wall of the mounting hole 2, and one end of the slide bar 301 is installed with a fixed shell 302, and the slide bar 301 is located in the inner cavity of the mounting hole 2, so that the upper cover 304 covers the mounting hole 2 for sealing. When there is high-pressure gas under the tray 1, the gas rushes into the mounting hole 2 through the gap between the bottom plate 305 and the slide bar 301, and the upper cover 304 is lifted to open the float valve, and vice versa, the bottom plate 305 pulls the slide bar 304 under the action of gravity. 01 moves downward, driving the float valve to close, and the device has better practicality. Compared with the traditional float valve with long sheet legs, the contact area between the slide rod 301 and the inner wall of the mounting hole 2 is smaller. The float valve assembly 3 is stuck at the port of the mounting hole 2 through the fixed shell 302 of the arc structure. The stability of the device is also guaranteed, and there is no need to worry about the float valve getting stuck, rusted or stuck, which is beneficial to solving the problem that the float valve is easily stuck, rusted or stuck during the operation of the existing float valve tower plate and cannot be opened freely. The rusted float valve must be replaced during the tower plate inspection, and the practicality of the device is poor.
