Description
Technical field
The utility model relates to filter, particularly at the complex sintered net filter cylinder of a kind of Hastelloy punched-plate that the industrial circles such as chemical industry, petrochemical industry, Coal Chemical Industry, environmental protection use.
Background technology
At chemical industry, petrochemical industry, Coal Chemical Industry, the industrial circles such as environmental protection, the complex sintered net filter cylinder of Hastelloy punched-plate is Coal Chemical Industry, fine chemistry industry, refining of hydrochloric acid, the alkylation of ethylbenzene, the crucial filter plant commonly used before booster pump in the systems such as acetic synthesis or after booster pump, the filter cylinder filtering material of current use is fixed for single-layer metal net and punched-plate resistance spot welding, volume circle is made, but in use, due to structure problem, wire netting and punched-plate fit clearance too large, and mesh is yielding, filtering accuracy not easily ensures, service life is short, because monofilament net rigidity is low, after using a couple of days, wire netting fracture is scrapped, cause unstable product quality, the wearing and tearing of booster pump or relevant device reduce service life, therefore, the innovation of existing filter cylinder and innovation are by being paid close attention in the industry.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide the complex sintered net filter cylinder of a kind of Hastelloy punched-plate, effectively can solve the problem that existing filter screen is yielding, intensity is low, service life is short, product quality can not be guaranteed.
The technical scheme that the utility model solves is; comprise alloy punched-plate and filter course; above alloy punched-plate, interfolded has lower protective layer successively; the hollow circle complex sintered net filter cylinder integrative-structure that filter course and up-protective layer are formed through vacuum-sintering; stack together in 45° angle between up-protective layer, filter course, lower protective layer, alloy punched-plate are often two-layer, the upper end of the complex sintered net filter cylinder of hollow circle is 45 ° of inclined plane shapes.
The utility model structure is simple, and novel unique, between each layer, contact point all combines together, and overall construction intensity is high, good rigidly, and mesh is even, and filtering accuracy is stablized.The utility model novel structure is unique, and flow resistance is low, and result of use is good, and intensity is high, and the life-span is long, and stock product steady quality after filtering, economic and social benefit is remarkable.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Provided by Fig. 1-2; the utility model comprises alloy punched-plate and filter course; above alloy punched-plate 4, interfolded has lower protective layer 3 successively; the hollow circle complex sintered net filter cylinder integrative-structure that filter course 2 and up-protective layer 1 are formed through vacuum-sintering; stack together in 45° angle between up-protective layer 1, filter course 2, lower protective layer 3, alloy punched-plate 4 are often two-layer, the upper end of the complex sintered net filter cylinder of hollow circle is 45 ° of inclined plane shapes.
In order to ensure result of use, described up-protective layer, lower protective layer are all form the netted of uniform meshes by wire track and column braiding, and mesh is 200-1000 micron square (shown in Fig. 3,5); Described filter course forms the netted of uniform meshes by wire track and column braiding, and mesh is square (as shown in Figure 4) of 20-500 micron; Described alloy punched-plate is shaped with uniform punching by alloy punching plate body upper punch to form (as shown in Figure 6); Described up-protective layer 1, filter course 2, lower protective layer 3, alloy punched-plate 4 stack together and form step-like filter opening structure.
As can be seen from said structure; the utility model filter cylinder is worked out by Hastelloy material that shaping three-layer metal net is interlaced to be stacked and form with the composite web of Hastelloy punched-plate together with vacuum-sintering; filter course is protected by up-protective layer, lower protective layer; alloy punched-plate, as support reinforcing layer, forms through vacuum drying oven sintering.For ensureing the characteristics such as the stable and flow resistance of strainability; filter course aperture of filter screen selects 20 microns of-500 microns of square hole nets to make; up-protective layer, lower protective layer select 200 microns of-1000 microns of square hole nets to make; alloy punched-plate thickness 0.8mm-5mm; punching is circular, also can be square opening, bar hole etc.This composite filter drum as required, can also make any one in the pattern filter elements such as straight tube, cone cylinder, ellipse, circle, square, rectangle.
From said structure, the utility model improves greatly one of existing filter cylinder, has:
1, flow resistance is low: complex sintered net keeps aperture to merge after sintering, does not have interlayer, can not accumulate foreign material, effectively can reduce flow resistance between wire side; Be specially adapted to low voltage difference large discharge filter;
2, strainability is stablized: the overall rigidity of the wire netting after sintering improves, and aperture is not yielding, guarantees filtering accuracy, stock product steady quality after filtering;
3, intensity is high: complex sintered net, and to be combined by vacuum drying oven high-temperature molten with other wire nettings as support reinforcing layer by one deck punched-plate, and integral rigidity is stronger, silk screen intensity is reached capacity, can under high pressure use;
4, the life-span is long: the wire netting after vacuum drying oven sintering is equivalent to five times of original product;
5, corrosion resistance is strong: Hastelloy corrosion resistance is stronger, and be mainly used in the strong corrosive media occasion that iron-based Cr-Ni or Cr-Ni-Mo stainless steel, nonmetallic materials etc. cannot use, economic and social benefit is remarkable.
