Abstract
The utility model relates to a filter drum, in particular to a punched-plate sintered mesh filter drum which is a filter device. The punched-plate sintered mesh filter drum comprises a drum body. An inner filter layer and an outer filter layer are compounded together in an enclosing mode to form the drum body. The inner wall of the outer filter layer is covered by the inner filter layer. The punched-plate sintered mesh filter drum is compact in structure, high in filter accuracy, strong in rigidity, high in compression-resistant strength, and good in stable performance.
Description
Technical field
The utility model is a kind of filter cylinder, and particularly a kind of punched-plate sintered meshwork filter cylinder is a kind of filter.
Background technology
Filter plant of the prior art, intensity is lower, and rigidity is relatively poor simultaneously, and the mesh shape is unstable, the effect that impact is filtered.
Chinese patent 200720190359.5 discloses a kind of metallic sintered net filter cartridge, relates to a kind of metallic sintered net filter cartridge of the filter plant for the various solution Separation of Solid and Liquid of alumina producing.It is characterized in that its structure comprises: sintered meshwork cylinder-this sintered meshwork cylinder is a tubular sintered metal mesh cylinder; Shrouding under the cartridge filter-this time shrouding is the metallic plate that edges of boards and the side weld of sintered meshwork cylinder doffing connect; Cartridge filter mounting flange-this mounting flange is that an end is the short metal tube of plane face flange structure, the upper port weld connection of the other end of short metal tube and sintered meshwork cylinder.The filter effect less of the cartridge filter of this structure, and location structure is complicated, and the cylindrical shell rigidity is lower.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and is simple in structure, and has accurately filtering accuracy, filtration resistance and the firm good punched-plate sintered meshwork filter cylinder of performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of punched-plate sintered meshwork filter cylinder comprises cylindrical shell, and described cylindrical shell is carried out mutually with outer filter course by the inner filtration layer and is encircled into, and the inwall of described outer filter course is carried out the inner filtration layer.
The existing uniform and stable filtering accuracy of this sintered meshwork has again higher strength and stiffness, and it is a kind of desirable filtering material that compression strength is required occasion high and grade of filtration requirement homogeneous.Because its strobe utility is both surface filtration, and the mesh duct is smooth, therefore it has excellent backwash and regeneration performance (can adopt counter-flow water, filtrate, ultrasonic wave, melt, cure etc.), can repeatedly use for a long time, be particularly suitable for the operating process of serialization and automation, any filtering material all can't be compared.
As preferably, the aperture of described inner filtration layer is less than the aperture of outer filter course.
As preferably, the upper end sidewall of described cylindrical shell is provided with 4 equally distributed upper locating holes, and the lower end sidewall of described cylindrical shell is provided with 4 equally distributed lower locating holes, and the cross section of described upper locating hole and lower locating hole is respectively trapezoidal shape.
Therefore, the punched-plate sintered meshwork filter cylinder that the utility model provides, compact conformation, filtering accuracy is high, and rigidity is strong, and is high to compression strength, and simultaneously firm performance is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, a kind of punched-plate sintered meshwork filter cylinder comprises cylindrical shell 1, and described cylindrical shell 1 is carried out mutually with outer filter course 3 by inner filtration layer 2 and is encircled into, and the inwall of described outer filter course 3 is carried out inner filtration layer 2.The aperture of described inner filtration layer 2 is less than the aperture of outer filter course 3.The upper end sidewall of described cylindrical shell 1 is provided with 4 equally distributed upper locating holes 4, and the lower end sidewall of described cylindrical shell 1 is provided with 4 equally distributed lower locating holes 5, and the cross section of described upper locating hole 4 and lower locating hole 5 is respectively trapezoidal shape.
