Abstract
The utility model relates to a grille in an adsorption chamber of a dewaxing molecular sieve of an alkylbenzene device, and the utility model is composed of a casing body, a grille net and rib grids, wherein, each of the grilles is disk-shaped. The utility model has the essential structure that each of the grilles made of stainless steel materials is a parted structure; the grille net is a stainless steel sphenoid welding strip-gap net which is fixedly connected to a frame together. Compared with the prior art, the net and the frame of the utility model are firmly connected, the grille net is not clogged, and the utility model has high intensity, convenient installation and maintenance, and high productive efficiency.
Description
Technical field
The utility model relates to a kind of wax molecular sieve device, and particularly a kind of oil refining container belongs to refining equipment with Alkylbenzene Unit wax molecular sieve adsorption chamber grid.
Background technology
Wax molecular sieve device adsorption chamber grid is provided with a lot of layers, every layer of grid is disc, every layer of grid has two-sided net or single face net, net all uses the different silk screen of multilayer thickness to be formed by stacking, silk screen and frame adopt general welding process, welding strength is weak, fragile, and the synergetic silk screen of multilayer very easily stops up, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art; and provide a kind of silk screen to adopt not susceptible to plugging stainless steel wedge shape welding bar seam net; the mode that net and frame adopt shielded welding to fixedly connected, the Alkylbenzene Unit wax molecular sieve adsorption chamber grid of corrosion-resistant, the high long service life of intensity.
The purpose of this utility model is achieved in that by frame, grid, muscle lattice, every layer of grid is disc, its structural feature is: the grid made from stainless material is a fraction block structure, grid adopts stainless steel wedge shape welding bar seam net, is fixed together between grid and the frame.
Described grid is weldingly fixed on by inferior arc-welding between frame.
Compared to existing technology, stainless steel wedge shape welding bar seam net of the present utility model and frame are connected firmly, do not stop up during use, and the intensity height, installation and maintenance are convenient, the production efficiency height.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is the improvement to existing wax molecular sieve adsorption chamber grid, improved position is, use multi-layer silk screen instead stainless steel wedge shape welding bar seam net, concrete structure such as Fig. 1, the utility model is made up of frame 1, stainless steel wedge shape welding bar seam net 2, muscle lattice 3 and container 4 etc., and every layer of grid is disc.Every layer of grid all adopts stainless material to make, and according to manufacturing technique requirent disk is divided into polylith, makes it become fraction block structure.Adopt stainless steel wedge shape welding bar seam net as Fig. 1 grid 2, the argon arc welding welding with shielded welding between stainless steel wedge shape welding bar seam net 2 and the frame 1 is fixed together.All grid muscle lattice 3 all adopt the argon arc welding welding to fixedly connected with frame 1.Grid is contained in the container 4, seals with filler 5 in the container 4.
Claims (2)
1, a kind of Alkylbenzene Unit wax molecular sieve adsorption chamber grid, become by frame, grid, muscle lattice, every layer of grid is disc, it is characterized in that: the grid made from stainless material is a fraction block structure, grid adopts stainless steel wedge shape welding bar seam net, is fixed together between grid and the frame.
2, Alkylbenzene Unit wax molecular sieve adsorption chamber grid according to claim 1 is characterized in that, stainless steel wedge shape welding bar seam net is weldingly fixed on by argon arc welding between frame.
