Description

Wave-folding filter cylinder with rigid framework for backwashing filter

Technical Field

The utility model relates to a strain a section of thick bamboo, especially a section of thick bamboo is strained to anti-washing filter with taking rigidity skeleton ripples.

Background

The automatic backwashing filter is widely applied to chemical industry, water treatment, medicine and other industries. For the filter cylinder for the full-automatic backwashing filter, the market is mainly divided into a corrugated filter cylinder and a non-corrugated filter cylinder at present, wherein the corrugated filter cylinder can increase the filtering area by 2-4 times after being folded, and the filter cylinder can be rapidly popularized and applied once coming out, but all inner frameworks used by the corrugated filter cylinder for the full-automatic backwashing filter at present are formed by welding thin-wall punching plates, and due to the structural problem, the cylindricity of the inner framework of the filter cylinder is inevitably poor, usually, the error of the cylindricity is at least more than 3mm, the smoothness cannot be effectively guaranteed, so that a suction nozzle is forced to leave the filter cylinder for a longer distance, the backwashing effect of equipment is greatly weakened, the ineffective consumption of a filter medium is increased, and the filter cylinder is fatal to the adoption of the suction nozzle type backwashing filter. Therefore, structural improvements and innovations in the prior art are imperative.

SUMMERY OF THE UTILITY MODEL

To the above situation, for solving prior art's defect, the utility model aims to provide a backwash filter strains a section of thick bamboo with taking rigid skeleton bending wave, can effectively solve because of the current interior skeleton cylindricity error of straining a section of thick bamboo is great, and the smooth finish can't be guaranteed, the poor and big problem of the invalid consumption of material of back flush effect.

In order to achieve the purpose, the technical scheme of the utility model is that, a section of thick bamboo is strained to back flush filter with taking rigidity skeleton bending wave, include protective layer, filter layer and strain a section of thick bamboo inner frame, it is hollow cylinder to strain a section of thick bamboo inner frame, and the bright and clean equipartition in surface has the round hole passageway, and the filter layer is the ring wave form, and the suit is at the surface of straining a section of thick bamboo inner frame, and outer protective layer suit is at the surface of filter layer, constitutes rigidity skeleton bending wave and strains a section of thick bamboo.

The utility model discloses an improve cylindricity and the interior surface finish degree of straining a section of thick bamboo inner frame, strengthened the back flush effect of equipment, reduced filter medium's invalid consumption, the waste residue volume that has significantly reduced reduces, reduces the waste material handling capacity in later stage, has practiced thrift filter medium.

Detailed Description

The details of the embodiments of the present invention are described below with reference to the accompanying drawings and the specific embodiments.

The utility model discloses in concrete implementation, give in combination with fig. 1-2, a backwash filter is with taking rigidity skeleton bending wave to strain a section of thick bamboo, include protective layer, filter layer and strain a section of thick bamboo inner frame, it is hollow cylinder to strain a section of thick bamboo inner frame 1, and the bright and clean equipartition in surface has round hole passageway 2, and filter layer 3 is the ring wave form, and the suit is at a surface of straining a section of thick bamboo

inner frame

1, and 4 suits of outer protective layer are at the surface of filter layer 3, constitute rigidity skeleton bending wave and strain a section of thick bamboo, strain a.

In order to ensure better implementation effect, the inner framework 1 of the filter cylinder is a hollow cylinder made of stainless steel or a hollow cylinder formed by rolling and welding steel plates, and the thickness of the inner framework is 5-15 mm.

The inner surface of the inner framework 1 of the filter cylinder has a smooth finish Ra0.4-1.6 mu m.

The outer protection layer 4 is of a grid-shaped cylindrical structure.

The inner diameter of the end cover 5 is larger than the inner diameter of the filter cartridge inner framework 1 and smaller than the outer diameter of the filter cartridge inner framework 1.

The utility model discloses when concrete production, roll up with steel pipe or steel sheet and weld into tubulose and strain a section of thick bamboo inner frame, and strain a section of thick bamboo inner frame's inner wall and process to the design size and guarantee to strain a section of thick bamboo inner wall smooth finish and reach Ra0.4 ~ 1.6 mu m through machining method, adopt machining method to process numerous equipartition circulation hole passageways and be used for the circulation of filter media on the section of thick bamboo wall of straining a section of thick bamboo inner frame again, again install the folded wave filter layer on this section of thick bamboo inner frame lateral surface, strain a section of thick bamboo inner frame and keep 5 ~ 15mm thick effective thickness after general processing, because thickness, make a section of thick bamboo inner frame's rigidity very high, the section of thick bamboo inner wall of straining a section of thick bamboo that processes through machining method simultaneously, can effectively guarantee it has very high smooth finish and very high precision cylindricity (can accomplish the cylindricity error generally under 0.1 mm), impurities are intercepted by the filter layer and stay in the wave trough of the inner surface of the folded wave filter layer, the backwashing suction nozzle can be infinitely close to the inner surface of the inner framework of the filter cylinder during backwashing, so that a large suction force can be formed on a filter cake in the wave trough of the folded wave filter layer, the filter cake can be effectively removed, meanwhile, the ineffective consumption of the filter medium leaked from the gap between the inner wall of the inner framework of the filter cylinder and the suction nozzle is greatly reduced, the waste residue amount is greatly reduced, the later-stage waste treatment amount is reduced, the filter medium is saved, the service life of the filter cylinder is prolonged, and the filter cylinder has good economic and social benefits.
