Abstract
The utility model discloses a closed filter, which comprises a cylinder. The top of the cylinder is provided with a feeding hole and a low-pressure gas inlet, and the bottom of the cylinder is provided with a group of filter sticks, a discharging hole and a liquid outlet. The closed filter is fine in solid-liquid separation effect, even in filter cake distribution, totally closed, free from leakage and zero in environmental protection.
Description
Technical field
The utility model belongs to chemical field, is specifically related to a kind of close filter.
Background technology
At present, the airtight filter plant of using always in the chemical field mainly contains: centrifugal filter, bag filter, chip filter, three-in-one filter and pressure filter etc.Wherein, centrifugal filter and pressure filter filter cake solid content are higher, discharging automatically, but obturation effect is poor, can't distill and drying material, and equipment material has limitation; Bag filter generally is used for the filtration of a small amount of filter cake, be used for the preceding coarse filtration of secondary filter, but volume is less, and discharging automatically also can't be distilled and drying material; The filter cake solid content is higher after the chip filter process, discharging automatically, and obturation effect is good, but can't distill and drying material, and equipment material has limitation; Three-in-one filter filter cake solid content is higher, is a kind of multi-functional solid-liquid separating equipment that integrates filtration, washing, drying, stirring, reaction, slags tap automatically, but when carrying out heat filtering; The filter plate below has material and separates out, and the easy blocking pipeline is during to filtration cakes torrefaction; Drying time is longer, and drying effect is not good, generally can not surpass 98% through dried material solid content; Material is selected for use also has limitation, for example can not use glass lined.
For filtering the chemical industry series products; For example in the building-up process of bisphenol S; Need under high temperature and severe corrosive condition, to filter, thereby need a kind of can the filtration and cheap filter plant, but at present filter plant some can not satisfy the material requirement; The very high precious metal material of a little selection price is arranged, so the present typical filter equipment of the filtration of bisphenol S is difficult to satisfy its requirement.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, and a kind of close filter that is used to filter the chemical industry series products is provided.
Technical scheme: in order to achieve the above object, the utility model is specifically realized like this: a kind of close filter, comprise a cylindrical shell, and the cylindrical shell top is provided with charging aperture and low-pressure gas import; The cylindrical shell bottom is provided with one group of filter stick, and the cylindrical shell bottom is provided with discharging opening and liquid outlet in addition.
In order to shift out residual liquid material, can set up one deck filter screen, filter cloth or other band poromerics at the liquid outlet place.
The gas that feeds the low-pressure gas import can be water vapour, solvent vapo(u)r, air and nitrogen etc.
Beneficial effect: compare with conventional art, the utlity model has following advantage:
(1) airtight fully, do not have and leak environmentally safe;
(2) can carry out Separation of Solid and Liquid in pressurization or vacuum condition, good separating effect, and filter cake is evenly distributed;
(3) can wash filter cake, clean result is better;
(4) for containing organic solvent material of (referring to the organic solvent molten especially) with shipwreck; After Separation of Solid and Liquid, can add suitable quantity of water and carry out azeotropic distillation, wherein remaining a small amount of organic solvent is steamed recovery; Water is applied mechanically when next azeotropic distillation; Can reduce solvent loss, reduce the pressure of post processing, reduce pollution environment;
(5) can adopt different material manufacturings according to the character of medium.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Shown in accompanying drawing, a kind of close filter that the utility model provides comprises a cylindrical shell 1, and cylindrical shell 1 top is provided with charging aperture 2 and low-pressure gas import 3; Cylindrical shell 1 bottom is provided with liquid outlet 6; Cylindrical shell 1 bottom is provided with one group of filter stick 4, and cylindrical shell 1 bottom is provided with discharging opening 5 and liquid outlet 6 in addition, and in order to shift out residual liquid material more up hill and dale, liquid outlet 6 outsides are covered with one deck filter screen, filter cloth or other poromerics.
During concrete operations, the material that will have solvent is put into filter, after material gets into filter fully; Close feeding mouth 2, open the filtrating discharging valve of filter stick 4, open low-pressure gas import 3; Liquid in the material is extruded through filter stick 4, and filtrating goes receiving tank to receive; Filtrating is closed filter stick 4 valves after extruding, and opens liquid outlet 6, and a small amount of liquid material that cylindrical shell 1 bottom is residual is pressed into the filtrating receiving tank and receives, and remaining solid material is then discharged from discharging opening 5 in the cylindrical shell 1.
Claims (2)
