Abstract
The utility model relates to a multi-stage filter for manual sewage disposal. The multi-stage filter comprises a cylinder body and a filter screen, wherein the axial line of the cylinder body is arranged horizontally, a medium inlet and a medium outlet are formed at the two ends of the cylinder body respectively, a maintenance hole is formed at the top end of the cylinder body, and a blowdown valve is arranged at the bottom end of the cylinder body. The multi-stage filter for manual sewage disposal has reasonable structural design, convenience in use, and can be widely used for filtration of serious medium in foreign matters.
Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of multistage filtering apparatus of manual blowdown.
Background technology
The medium of general civilian heating system adopts the hot water person comparatively general, and before entering equipment such as heat exchanger or water pump at hot water, usually need to install filter for installation, purpose is to prevent because hot water impurity is more damage equipment, minimizing service life of equipment, reduction exchanger heat exchange efficiency, increases SR etc.If hot water impurity is few, system is cleaner, the accurate filter of one-level generally is installed is got final product.Yet for the such thermal source of steel plant's remaining hot water, the impurity especially severe adopts accurate filter can influence the flowability of thermal source, be unfavorable for heating, but thermal source is very sufficient, stable, need not promptly be waste, in this case, press for a kind of filter that is applicable to the medium that impurity is many.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and is easy to use, is fit to the multistage filtering apparatus of the manual blowdown of the more medium of impurity screening.
In order to address the above problem, the utility model by the following technical solutions:
A kind of multistage filtering apparatus of manual blowdown comprises cylindrical shell and screen pack, and tubular axis is and is horizontally disposed with, and the cylindrical shell two ends are respectively equipped with medium inlet and media outlet, and cylinder top is provided with manhole, and the cylindrical shell bottom is provided with blowoff valve.
Described screen pack comprises one-level screen pack, cascade filtration net and three-stage filtration net, and three screen packs are arranged in order setting and cylindrical shell is divided into cavity A, cavity B, cavity C and cavity D four parts in cylindrical shell.
The mesh diameter of described screen pack reduces successively according to one-level screen pack, cascade filtration net and putting in order of three-stage filtration net.
Described cavity A, cavity B and cavity C bottom are respectively equipped with a blowoff valve.
Described cylinder inboard wall is provided with holddown groove, and one-level screen pack and cascade filtration net are installed in the cylindrical shell by holddown groove respectively, and the three-stage filtration net is made the tubular construction of an end opening, and opening one end is connected with media outlet.
Compared with prior art, the beneficial effects of the utility model are:
The utility model novel structure, easy to use, by a plurality of screen packs isolated by filtration impurity step by step, kept the cleanliness factor of medium to greatest extent, make remaining hot water be used for civilian heating fully, protected equipment, improved the service life of equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of multistage filtering apparatus of manual blowdown as shown in Figure 1, comprises cylindrical shell 1 and screen pack, and cylindrical shell 1 axis is and is horizontally disposed with, and cylindrical shell 1 two ends are respectively equipped with medium inlet 6 and media outlet 11, and cylindrical shell 1 top is provided with manhole 4, and cylindrical shell 1 bottom is provided with blowoff valve 7.Screen pack comprises one-level screen pack 8, cascade filtration net 9 and three-stage filtration net 10, three screen packs are arranged in order setting and cylindrical shell 1 are divided into cavity A5, cavity B3, cavity C13 and cavity D12 four parts in cylindrical shell 1, cavity A5, cavity B3 and cavity C13 bottom are respectively equipped with a blowoff valve 7.The mesh diameter of screen pack reduces successively according to one-level screen pack 8, cascade filtration net 9 and putting in order of three-stage filtration net 10.Cylindrical shell 1 inwall is provided with holddown groove 2, and one-level screen pack 8 and cascade filtration net 9 are installed in the cylindrical shell 1 by holddown groove 2 respectively, and three-stage filtration net 10 is made the tubular construction of an end opening, and opening one end is connected with media outlet 11.
The utility model filter is mainly used in the more serious remaining hot water thermal source medium of impurity, remaining hot water 6 enters filter cavity A5 through the medium inlet, behind the primary filter of one-level screen pack 8, enter cavity B3, enter cavity C13 through cascade filtration net 9 again, enter cavity D12 through three-stage filtration net 10 again, after media outlet 11 outflows.Impurity in cavity A5, cavity B3 and the cavity C13 can manually be discharged by the blowoff valve 7 of its bottom respectively, and the mesh diameter of three screen packs reduces gradually, and filtering accuracy increases gradually.The mesh diameter of screen pack can be determined according to the impurity situation in the medium and the filtering accuracy of requirement.For guaranteeing the intensity of screen pack, one-level screen pack 8 and cascade filtration net 9 need be connected with holddown groove 2 in the cylindrical shell 1 by bolt, screen pack can adopt the bigger material of white steel equal strength to make, because the diameter of mesh is more and more littler, three-stage filtration net 10 is made tubular, can increase circulation area, reduce resistance.In addition, cylindrical shell 1 diameter is greater than inlet duct diameter several times.If the impurity in cavity A5 and the cavity B3 is more, 7 rows are not thorough by following blowoff valve, can remove by top manhole 4 respectively yet.This filter is fit to the use in parallel of many groups, and valve is joined in both sides, the both sides valve closing can be stopped transport one group when needing maintenance or blowdown, resumes operation after the maintenance blowdown again.
