Abstract
The utility model relates to a polyether filtering device, which belongs to the field of chemical equipment and comprises a barrel body, wherein a filtering screen barrel is arranged in the barrel body, an upper flange cover is arranged at the top of the barrel body, and a feeding port, a discharging port and supporting legs are arranged on the barrel body. The polyether filtering device is characterized in that the volume of the barrel body is 0.18 to 0.22 m3, the diameter of each mesh of the filtering screen barrel is 8 to 12 mm, and a lower flange cover is arranged at the bottom of the barrel body. By increasing the volume of the barrel body and diameters of the meshes of the filtering screen barrel, the total area of a filtering screen is greatly larger than the sectional area of a material delivering pipeline, and filtering efficiency is greatly improved. Besides, the increase of the volume of the barrel body has a function of a buffer tank, thereby guaranteeing flow and pressure in the material delivering pipeline and shortening material discharging time. The flange cover at the bottom of a filter replaces an original blind plate, thereby bringing great convenience for overhaul and cleaning operations due to increase of inside space and the movable flange cover, reducing cleaning frequency of the device and improving cleaning efficiency.
Description
Technical field
The utility model relates to a kind of polyethers filter plant, belongs to the chemical industry equipment field, the filter that uses in particularly a kind of polyethers production process.
Background technology
At present, the polyethers filter is the auxiliary equipment of polyether reactant still, mainly the crystalline particle that produces in the polyether reactant process is filtered, and will filter the back product by discharge pump and enter the product jar, at discharge pump porch mounting filtering device.The T type filter of general employing standard, the filter cylinder volume is less, and the mesh of filtering net cylinder is less; General mesh diameter is 6mm, along with the prolongation of filtration time, and the mesh obstruction of depositing easily; Bring very big resistance to flow rate of fluid; Influenced the flow and the pressure of pipeline inner fluid, prolonged the finished product discharge time, filter efficiency is lower.
The about 0.015m of cylindrical shell volume of general T type filter
3, and the solid particle diameter that produces in the polyethers production process is bigger, and amount is many, and the volume of filter is too little, in the time of the easy blocking strainer screen, easily filter is filled up, and can not play a role in filtering, and volume is little, and also to cause clearing up difficulty big, and cleaning cycle is short.
Standard T type filter cylindrical shell only adopts the blind flange sealing at the top, be used to clear up filter.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of above-mentioned defective that solved is provided, has increased filter efficiency, improved the polyethers filter plant of cleaning efficiency.
The utility model solves the technical scheme that its technical problem adopted: described polyethers filter plant; Comprise cylindrical shell; Be provided with filtering net cylinder in the cylindrical shell; The cylindrical shell top is provided with the upper flange lid, also is provided with charging aperture, discharging opening and supporting leg on the cylindrical shell, and it is characterized in that: the volume of cylindrical shell is 0.18～0.22m
3, the mesh diameter of filtering net cylinder is 8～12mm, the lower flange lid is equipped with in the bottom of cylindrical shell.
Cylindrical shell volume after the dilatation has reached 0.18～0.22m
3, the mesh diameter of filtering net cylinder increases to 8～12mm by 6mm, makes the filter screen gross area be far longer than the sectional area of feeding pipe; Filter efficiency is greatly improved; Volume increases the effect of having played surge tank simultaneously, has guaranteed flow and pressure in the feeding pipe, has shortened the discharge time.Filter bottom adopts blind flange to substitute original blind plate, and the increase of inner space brings great convenience for the maintenance cleaning work with movable blind flange, has reduced the equipment cleaning frequency, has improved cleaning efficiency.
Described cylindrical shell volume is preferably 0.20m
3
The mesh diameter of described filtering net cylinder is preferably 10mm.
Described cylindrical shell top is equipped with evacuated tube.
Described cylindrical shell bottom is equipped with discharging tube.
Evacuated tube and discharging tube can be more convenient barrel is cleared up is set, further improved cleaning efficiency.
The beneficial effect that the utility model had is: the polyethers filter plant is through increasing the mesh diameter of cylindrical shell volume and filtering net cylinder; Make the filter screen gross area be far longer than the feeding pipe sectional area, filter efficiency is greatly improved, the cylindrical shell volume increases the effect of having played surge tank simultaneously; Flow and pressure in the feeding pipe have been guaranteed; Shortened the discharge time, filter bottom adopts blind flange to substitute original blind plate, and the increase of inner space brings great convenience for the maintenance cleaning work with movable blind flange; Reduce the equipment cleaning frequency, improved cleaning efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, cylindrical shell; 2, filtering net cylinder; 3, upper flange lid; 4, charging aperture; 5, discharging opening; 6, supporting leg; 7, lower flange lid; 8, evacuated tube 9, discharging tube.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; Be provided with filtering net cylinder 2 in the cylindrical shell 1, cylindrical shell 1 top is provided with upper flange lid 3, also is provided with charging aperture 4, discharging opening 5 and supporting leg 6 on the cylindrical shell 1; Wherein filtering net cylinder 2 is positioned at the middle and lower part of cylindrical shell 1; Spatial communication between charging aperture 4 and filtering net cylinder 2 tops and cylindrical shell 1 top, the spatial communication that discharging opening 6 and cylindrical shell 1 inwall and filtering net cylinder 2 outer walls surround, the volume of cylindrical shell 1 is 0.18～0.22m
3, the mesh diameter of filtering net cylinder 2 is 8～12mm, and lower flange lid 7 is equipped with in the bottom of cylindrical shell 1, and cylindrical shell 1 top is equipped with evacuated tube 8, and the bottom is equipped with discharging tube 9.
This polyethers filter plant is installed in polyether reactant still discharge pump porch, is filtered the filtering net cylinder 2 that material flows in the cylindrical shell 1 through charging aperture 4 through feeding pipe, and material is flowed out by discharging opening 5 after filtering net cylinder 2 filters.Be filtered net tube 2 in the cylindrical shell 1 and be divided into two spaces; Material flows in the filtering net cylinder 2 earlier; Because the pressure in the feeding pipe makes and produce pressure differential between charging aperture 5 and the discharging opening 6, the material mesh through filtering net cylinder 2 under external force flows in the space that filtering net cylinder 2 and cylindrical shell 1 surround, and this space links to each other with discharging opening 5; Material reaches filter effect when the mesh through filtering net cylinder 2, filter the back and flow out these filter plants by discharging opening 5.
