Abstract
The utility model relates to a spherical surface filter screen in secondary filter screen equipment. The filter screen comprises a filter screen frame and a filter core, wherein the filter screen frame is in a bowl-shaped structure and comprises a hollow support, a supporting flange and a certain quantity of water deflectors; the support and the supporting flange are coaxially arranged; the support is used as the bottom of the bowl-shaped structure; and the supporting flange is used as the edge of the bowl-shaped structure; the certain quantity of water deflectors are uniformly arranged along the circumferential direction of the bowl-shaped structure; and the outer side edge of each of the water deflectors is in an arc shape; the filter core is arranged between the adjacent water deflectors; the plane of the filter core is also in an arc shape; and the radian of the plane of the filter core is the same as the radian of the outer side edge of each of the water deflectors. The filter screen has simple, smart and reasonable structure, is in a spherical surface structure in the whole, is convenient to process, install and maintain, saves materials, has attractive appearance, good sewage disposal effect, prolongs the service life of the filter core and can more reliably ensure the normal operation of the equipment.
Description
Technical field
The utility model belongs to the filter plant technical field, relates to the filter in a kind of circulation, specifically the sphere screen pack in the secondary filter equipment.
Background technology
In the supply and drain water system of industries such as Hydraulic and Hydro-Power Engineering, thermal power plant, metallurgy, chemical industry and municipal works, secondary filter is a kind of drainage sewage disposal apparatus commonly used, it can tackle and remove foreign material such as discarded in aquatic organism such as weeds in the current, leaf, fishes and shrimps and industrial or agricultural and the urban life effectively, make filtered water reach certain condition of water quality, replace manually removing contamination, reducing labor intensity, satisfy the job requirement that follow-up equipment purifies water.Secondary filter equipment have filter reliable, current are unimpeded, scrubbing is effective, operate steadily, noise is little, it is big to bear hydraulic pressure, safe and reliable, simple in structure, easy to maintenance, be applicable to seawater, the different water quality requirement of fresh water, configuration pressure difference switch measuring system can realize automation remote control.
For secondary filter equipment, its inner screen pack is the key core parts, is determining the quality of this equipment.Screen pack of the prior art generally is made up of screen frame and filter core.Filter core generally adopts the punched-plate welding, and on the one hand, processing time consuming is taken material, and inconvenience is installed; On the other hand, when secondary filter carries out backwash, blowdown funnel can be removed contamination one by one to the screen pack filter core, but in the long-term operation process, the five equilibrium device may cause blowdown funnel can not prepare to arrive the position (position of removing contamination is that blowdown funnel is corresponding with the monolithic filter core) of removing contamination with the transmission accumulated error of transmission system, be adsorbed on the dirt easy-clear not on the filter core, reduced effective area of passage simultaneously, after long-term the use, can't guarantee filter core front and back pressure reduction within normal range (NR), thereby have a strong impact on the normal operation of recycle unit.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sphere screen pack that is applied on the secondary filter equipment is provided, and this filter screen structure is simple, ingenious, reasonable, and integral body is spherical structure, and is easy to process, and saves material; Filth-discharging effect is good, the filter core long service life.
The technical scheme that provides according to the utility model: the sphere screen pack in the secondary filter equipment, comprise screen frame and filter core, it is characterized in that: described screen frame is a bowl shaped structure, it comprises the water fender of bearing, pivot flange and the some of hollow; Described bearing and pivot flange coaxial arrangement, bearing are as the bottom of bowl shaped structure, and pivot flange is as the edge of bowl shaped structure; The water fender plate of described some arranges evenly that along the circumferencial direction of bowl shaped structure the outer side edges of water fender is an arc; Described filter core is arranged between the adjacent water fender, and the plane of filter core also is an arc, and the radian on filter core plane is identical with the radian of baffle plate outer side edges.
As further improvement of the utility model, described filter core is formed by steel plate punching and bending.
As further improvement of the utility model, the inner side edge of described water fender is provided with the end face shrouding.
The utility model compared with prior art, advantage is: (1), simple in structure, ingenious, reasonable, wholely be spherical structure, easy to process, and save material, install maintenance conveniently, good looking appearance; (2), filth-discharging effect is good, prolonged the service life of filter core, guarantees the normal operation of equipment more reliably.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the A-A office cutaway view among Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, described sphere screen pack is applied in the secondary filter equipment, and it mainly is made up of screen frame and filter core 1.Described screen frame is a bowl shaped structure, and it mainly is made up of the water fender 2 of bearing 4, pivot flange 3 and the some of hollow; Described bearing 4 and pivot flange 3 coaxial arrangement, bearing 4 is as the bottom of bowl shaped structure, and pivot flange 3 is as the edge of bowl shaped structure; Water fender 2 plates of described some arrange evenly that along the circumferencial direction of bowl shaped structure the outer side edges of water fender 2 is an arc; Described filter core 1 is arranged between the adjacent water fender 2, and the plane of filter core 1 also is an arc, and the radian on filter core 1 plane is identical with the radian of baffle plate outer side edges.
As shown in Figure 3, the inner side edge of described water fender 2 is provided with end face shrouding 5.End face shrouding 5 can make not only that structure of the present utility model is reliable more firmly be the more important thing is, end face shrouding 5 can compensate the five equilibrium device in the secondary filter equipment and the accumulated error of transmission system, improves the clean-up capability of secondary filter equipment.
The utility model is compared with existing screen pack, has simplified the version of screen pack, only needs a first assembly welding to form the screen pack framework, again filter core 1 is loaded in the screen frame one by one, the sphere screen pack.Filter core 1 is formed by steel plate punching and bending, need not welding, easy to process and saving material.
