Description

Technical Field

[0001] The utility model relates to the technical field of demisters, in particular to a wire mesh demister for a distillation kettle. Background Art

[0002] Wire mesh demisters are mainly used in the production process of chemical, petroleum, pharmaceutical, electric power, metallurgy and other industries. The wire mesh in the wire mesh demister is a gas-liquid filter made of various materials, and the gas-liquid filter is composed of metal wire or non-metallic wire. In the industrial production process, the liquid will produce a lot of foam. The presence of foam will affect the normal process, reduce production efficiency, and even cause safety hazards. The wire mesh demister can intercept the foam in the liquid and remove the foam.

[0003] The wire mesh demister is formed by splicing a wire mesh block composed of several wire meshes and wire mesh grids. When the wire mesh demister is used in a distillation kettle, in order to facilitate the installation and removal of the stirring shaft of the distillation kettle, the stirring shaft is divided into a short axis and a long axis, and connected to each other through a flange. The flange is located in the middle round hole of the wire mesh demister. The middle round hole of the existing wire mesh demister is generally not closed, and the internal wire mesh is easy to pass through the wire mesh grid and get entangled on the screws in the rotating flange. After the wire mesh is stirred out, it will lose its defoaming function, and the stirring shaft of the distillation kettle will be worn by the effect of the wire mesh being stirred out, thereby affecting the service life. Utility Model Content

[0004] The purpose of the utility model is to provide a wire mesh demister for a distillation kettle to solve the problems raised in the above background technology.

[0006] Preferably, the fixed inner ring is a ring structure.

[0007] Preferably, the wire mesh block comprises a grille, and the fixed inner ring is fixedly connected to the grille.

[0008] Preferably, two adjacent grilles are connected by fastening bolts.

[0009] Preferably, a fixed outer ring is coaxially arranged outside the fixed inner ring, and the fixed outer ring is fixedly installed on the outer ring of the demister body, and the fixed outer ring is an annular structure.

[0015] The wire mesh demister of the distillation kettle has the following beneficial effects:

[0016] The wire mesh demister for the distillation kettle is provided with a fixed inner ring at the circular hole in the center of the demister body. The fixed inner ring surrounds the circular hole in the demister body, so that the wire mesh block does not contact the moving equipment (i.e. the stirring shaft of the distillation kettle), thereby preventing the wire mesh from being stirred out. This can prevent the demister body from being damaged and increase the service life of the stirring shaft of the distillation kettle. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 2As shown, the utility model provides a wire mesh demister for a distillation kettle, including a demister body, which is formed by splicing a plurality of wire mesh blocks 1, a supporting device 2 is arranged at the bottom of the wire mesh block 1, the supporting device 2 is fixed in the distillation kettle, the supporting device 2 is two supporting rods, and the two supporting rods play a supporting role for the demister body.

[0025] Among them, Figure 3 As shown, a circular hole is opened at the center of the demister body, and a protective structure is arranged at the circular hole. The protective structure is a fixed inner ring 4 made of steel plate. The fixed inner ring 4 is fixedly installed on the demister body and is coaxially arranged with the circular hole. The fixed inner ring 4 is an annular structure.

[0026] Specifically, the wire mesh block 1 includes a grille 11 , a wire mesh 12 is arranged inside the grille 11 , and a fixed inner ring 4 is fixedly installed on the grille 11 .

[0027] In this embodiment, a fixed inner ring 4 is installed at the circular hole in the center of the demister body, and the fixed inner ring 4 surrounds the circular hole in the demister body, thereby closing the grid 11 in the wire mesh block 1, so that the wire mesh block 1 does not contact the moving equipment (i.e., the stirring shaft of the distillation kettle), thereby preventing the wire mesh 12 from being stirred out of the grid 11, thereby preventing the demister body from being damaged and increasing the service life of the stirring shaft of the distillation kettle.

[0028] like Figure 3-Figure 5 As shown, two adjacent grilles 11 are connected with fastening bolts 6, through which several wire mesh blocks 1 are fixed to each other to form a whole, avoiding looseness between the wire mesh blocks 1 (the wire mesh blocks 1 are only stuck to each other by size, which will lead to poor structural stability of the entire demister body), and can also prevent falling due to poor clamping force between the wire mesh blocks 1 when there are a large number of wire mesh blocks 1.

[0029] Furthermore, a fixed outer ring 5 is coaxially arranged outside the fixed inner ring 4. The fixed outer ring 5 is made of steel plate and is fixedly installed on the grille 11 of the outer ring of the demister body. The fixed outer ring 5 is a ring-shaped structure, and the fixation between the several wire mesh blocks 1 is further strengthened by the fixed outer ring 5.

[0030] In another embodiment, Figure 2-Figure 4 As shown, a pressing block 7 is arranged on the wire mesh block 1. The pressing block 7 is an I-beam. The structural strength of the I-beam is relatively high, which is more conducive to the fixation of the wire mesh block 1. A pressure strip 3 is also arranged above the wire mesh block 1. The pressure strip 3 is fixed in the distillation kettle, and the pressure strip 3 is detachably connected to the pressing block 7. The disassembly method includes but is not limited to bolts and buckles. The upper wing plate of the I-beam is fixed on the pressure strip 3, and the lower wing plate is in contact with the wire mesh block 1.

[0031] The inventors found that if Figure 1As shown, in the prior art, since a demister is generally not provided in the distillation kettle, and the demister additionally installed by the operator during use will have an error with the installation structure in the distillation kettle, a gap will be formed between the pressure strip 3 and the wire mesh block 1, which makes it difficult for the pressure strip 3 to press the demister body. The demister body is easy to move up when it is not pressed, and there is a risk of contact with the stirring shaft of the distillation kettle.

[0032] In the present application, a corresponding pressing block 7 is selected according to the gap height between the pressing strip 3 and the wire mesh block 1, the pressing block 7 is placed between the pressing strip 3 and the wire mesh block 1, and the pressing block 7 is fixed on the pressing strip 3. At this time, the pressing block 7 can press the demister body, limit the displacement of the demister body, and make the demister body safer during use.

[0033] Working principle: By installing a fixed inner ring 4 at the circular hole in the center of the demister body, the grille 11 in the wire mesh block 1 is closed, so that the wire mesh block 1 does not contact the moving equipment, and the wire mesh 12 is prevented from being stirred out of the grille 11. The demister body is pressed by the pressing block 7 and the pressure strip 3, thereby limiting the displacement of the demister body.

[0034] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
