Description

Technical Field

[0001] The utility model relates to the field of distillation columns, in particular to a distillation column facilitating foam removal. Background Art

[0002] A distillation column is a modern term referring to a chemical equipment made of rare metals such as titanium and their alloy materials, which is widely used in the fields of chemical industry, petrochemical industry, metallurgy, light industry, textile, soda making, pharmacy, pesticide, electroplating, electronics, etc. Generally, a corresponding demister is installed above the interior of the distillation column to clean the surface foam, making the liquid at the reaction part of the distillation column purer.

[0003] In the prior art, a distillation column facilitating foam removal proposed in the utility model patent with the publication number of CN 218793920 U is provided. Through a support frame docked with a docking seat, it is convenient to quickly assemble the distillation column. Through the setting of a slider and a chute, it is convenient to quickly limit and install the demister on the distillation column. Through a limiting strip to limit the hoisting rope, the hoisting of the distillation column body is made more stable.

[0004] However, it does not have the ability to automatically clean the demister. During use, it is necessary to more frequently take out and replace the demister or clean it manually, which is time-consuming and laborious in operation and requires shutdown for cleaning, greatly reducing the working efficiency of the device. At the same time, it does not have the ability of free combination and partial disassembly and replacement of the distillation column. Therefore, we need to upgrade and transform on the basis of the prior art to overcome the problems and deficiencies it has. Content of the Utility Model

[0026] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation manners.

[0027] As Figure 1 -4 shows, the design of a distillation column facilitating defoaming provided in this embodiment includes a device body 1. The device body 1 contains a lower column body 2. Two groups of support frames 3 are symmetrically arranged at the bottom of the lower column body 2. The upper end of the lower column body 2 is connected to an upper column assembly 4. An upper cover 5 is arranged at the top of the upper column assembly 4, and a cleaning assembly 7 is installed inside the upper cover 5. Two groups of air outlets 6 are symmetrically arranged on both sides of the upper cover 5. A defoamer 8 is arranged at the lower end of the cleaning assembly 7, and a mounting plate 9 is arranged at the lower end of the defoamer 8.

[0028] Preferably, the cleaning assembly 7 includes a motor 71. The lower end of the motor 71 is connected to a spline sleeve 73. A spline shaft 74 is correspondingly inserted at the lower end of the spline sleeve 73. A movable plate 75 is fixed at the lower end of the spline shaft 74. The movable plate 75 is rotatably installed at the center of the defoamer 8 and a cleaning brush 76 is arranged at the lower end. The motor 71 is arranged on the top of the upper cover 5 and an outer side is sleeved with a motor bracket 72. The motor bracket 72 is fixed on the upper cover 5. The cleaning brush 76 is attached to the surface of the defoamer 8;

[0029] The cleaning component 7 facilitates driving the cleaning brush 76 to rotate on the demister 8, thereby enabling simple cleaning of the demister 8, avoiding blockage problems that may affect the processing progress of the distillation equipment, eliminating the need for frequent manual cleaning or replacement of the demister 8, with simple and convenient operation, greatly improving the working efficiency and practicality of the device.

[0030] Preferably, the upper tower component 4 includes a connection port 41. At the upper end of the connection port 41, there is a lower conduit 42. At the upper end of the lower conduit 42, there is an upper conduit 43. The upper conduit 43 is connected to the lower end of the upper cover 5. There are two sets of flanges 44 between the connection port 41, the lower conduit 42, the upper conduit 43, and the upper cover 5. The flange 44 is provided with mounting holes 45, and fixing bolts 46 are screwed through the mounting holes 45. In both the lower conduit 42 and the upper conduit 43, there are mating docking grooves 47 and docking rings 48. The docking ring 48 is correspondingly inserted into the docking groove 47, and a sealing gasket 49 is installed at the top.

[0031] The upper tower component 4 formed by splicing multiple conduits can discharge the distilled gas inside the lower tower body 2. At the same time, the height of the upper tower component 4 can be selected appropriately through splicing, facilitating the user to customize and freely assemble the upper tower component 4 according to requirements. The operation is convenient and the adaptability is good, improving the flexibility and practicality of the device.

[0032] The working principle and process of the present utility model: During use, the lower tower body 2 and the upper tower component 4 cooperate to perform distillation operations on the liquid inside the equipment. During the distillation process, the demister 8 filters the foam generated during distillation to avoid affecting the distillation quality. After using for a certain period of time, the motor 71 can be controlled to work through an external power source. The motor 71 drives the spline sleeve 73 to rotate, the spline sleeve 73 drives the spline shaft 74 to rotate, and then drives the movable plate 75 and the cleaning brush 76 to rotate accordingly. The cleaning brush 76 rotates on the demister 8 and scrapes the surface of the demister 8 to avoid blockage that may affect the distillation operation. During the on-site installation or transportation of the equipment, the upper tower component 4 can be disassembled and assembled through the cooperation of the fixing bolts 46 and the mounting holes 45. The lower conduit 42, the upper conduit 43, and the upper cover 5 are all disassembled, and combined or freely spliced according to on-site requirements and usage requirements, greatly improving the adaptability of the device and facilitating different usage conditions and requirements.

[0033] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] In the description of this embodiment, the orientation or positional relationship terms such as "upper", "lower", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
