Dish formula filter
Technical field
The utility model relates to a kind of dish formula filter, specifically a kind of dish formula filter that is used for removing additive activated carbon that technical process adds etc.
Background technology
At present, the accurate filter that is applied to industries such as medicine company, food and chemical industry mainly contains filer element type and stacked two kinds.Wherein the filer element type filter adopts the polypropylene superfluorescent fiber to melt and spray shape or line twines the honeycomb like structure filter element, major defect is that volume is big, filter core easily blocked thoroughly clean up difficulty and change the core cost high; The filter core of laminated filter adopts a large amount of very thin circular laminations to be piled up and to lock and forms, its major defect is that lamination sticks together easily when being subjected to the influencing of organic matter and chemical impurity in the liquid, the residual liquid amount is big, therefore filter efficiency is low, and impurity particle is difficult for thoroughly being cleaned up, consider the core inefficacy thereby make, therefore need often transposing filter core, the use cost height.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective that exists on the existing accurate filter, provides that a kind of filter area is big, the raffinate amount is few, impurity particle can abandon with filter paper, no leakage, volume dish formula filter little, removable and simple to operate.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dish formula filter, be formed by connecting by pump, support, pipeline, tank body, Pressure gauge and dish formula filter assemblies, cylindrical shell, upper flange and end flange are formed the filtration tank body, be provided with gasket seal between upper flange and the end flange, and connect fixing seal, in the middle of end flange, be provided with filtrate (liquid by several slip-knot bolt assemblies; The right is provided with the filtrate inlet; The left side is provided with waste liquid outlet, is provided with compressed air in the middle of the cylindrical shell arc surface and imports and exports Shu Jie; The right is provided with Pressure gauge and connects Shu Jie, in the cylindrical shell of sealing, stack array on the end flange successively by pressure ring, filtering table, the filter element that pedestal and mozzle are formed, be placed with the filter paper of suitable filtering accuracy on the filtering table, last group filter element is provided with pressing plate, is connected by several bolt assemblies to compress between end flange and pressing plate.
Filter paper can be made by PTFE, spin laced fabric and filter cloth.The cylindrical shell surfaces externally and internally can machine glazed finish or electrochemical polish as requested.Whole dish formula filter can be placed in belt wheel movably on the pallet.
The beneficial effects of the utility model are: owing to adopted array to be placed with the dish formula filtering table of filter paper as filter element, filter area increases and can be by regulating the quantity of filtering table, make its reasonable disposition, thereby the raffinate amount is reduced, according to the difference of filtering accuracy being required and applying working condition different, can select the filter paper of suitable accuracy and to the replacing of the filter paper side of carrying out, simple to operate, the filter efficiency height; Adopt above structure and surface treatment method simultaneously, make dish formula filter no leakage, volume little, move flexibly and meet the GMP authentication requesting, fields such as medicine company, food, chemical industry, grease and machinery be can be widely used in, additives such as the activated carbon that adds in the technical process such as activated carbon etc. are particularly useful for removing.

Accompanying drawing 1 is a fundamental diagram of the present utility model.
Accompanying drawing 2 is structure assembling schematic diagrames of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
At Fig. 1, among Fig. 2, dish formula filter, form by pump, support, pipeline, tank body, Pressure gauge and the connection of dish formula filter assemblies, cylindrical shell 10, upper flange 3 and end flange 1 constitute and filter tank body, are provided with gasket seal 2 between the upper flange 3 of cylindrical shell 10 and end flange 1, by several slip-knot bolt assemblies 12 cylindrical shell 10 is sealedly connected and fixed with end flange 1 and is in the same place, in the middle of end flange 1, be provided with filtrate (liquid 14; The right is provided with filtrate inlet 13; The left side is provided with waste liquid outlet 15, is provided with compressed air in the middle of the cylindrical shell 10 top arc surfaces and imports and exports bundle joint 11; The right is provided with and connects Pressure gauge jin bundle joint 16, in the cylindrical shell 10 of sealing, stack array on the end flange 1 successively by pressure ring 5, the filter element that filtering table 4, pedestal 7 and mozzle 8 are formed, be placed with the filter paper of suitable filtering accuracy on the filtering table 4, last group filter element is provided with pressing plate 9, is connected by several bolt assemblies 6 to compress between end flange 1 and pressing plate 9.The filter paper that filter medium that the root a tree name is different and filtering accuracy select for use PTFE, spin laced fabric or filter cloth to make; And the root a tree name requires cylindrical shell 10 surfaces externally and internallies that machine glazed finish or electrochemical polish can be set, and whole dish formula filter can be placed in belt wheel movably on the pallet simultaneously.During filtration, filtered fluid enters in the cylindrical shell 10 by filtered fluid inlet 13 under the effect of pump, when liquid is full of cylindrical shell 10, under differential pressure action, liquid enters pedestal 7 by the filter paper of the suitable filtering accuracy on the filtering table 4, and the pipeline flow-direction filtrate (liquid 14 from being made up of base assembly.Particle bigger in the former filtrate is dammed on the surface of filter paper by filter paper, and when the surface of filter paper had a large amount of filter cakes to cover, the rate of filtration obviously slowed down, the pressure gauge reading that is connected on the bundle joint 16 obviously increases, at this moment, cut off pump, the transmitted beam joint feeds an amount of compressed air for 11 mouthfuls, make the inner most filtered fluids of filtering container finish last filtration, then, open waste liquid outlet 15, open slip-knot bolt assembly 12 at last, take off cylindrical shell 10, change filter paper and clean cylindrical shell etc. simultaneously.
