Abstract
The utility model discloses an improved grille pollutant remover structure, which belongs to equipment for intercepting and fishing out floaters and other sundries in water. The improved grille pollutant remover structure combines thick grilles, midsize grilles and thin grilles into a whole, the thin grilles are positioned at the lower part, and the thick grilles (or the midsize grilles) are positioned at the upper part; the thin grilles at the lower part are used for the conditions that the flow rate is small and the intercepting size requirement is high (the space between grizzly bars is small); and the whole grille (including the thin grilles at the lower part and the thick grilles or the midsize grilles at the upper part) are used for the conditions that the flow rate is large and the intercepting size requirement is low (the space between the grizzly bars is large). The technical proposal of the improved grille pollutant remover structure realizes the capacity that a single grille can serve multiple work conditions. The improved grille pollutant remover structure has the beneficial effects of effectively reducing the volume and the number of equipment and reducing the equipment occupying area.
Description
Technical field
The utility model belongs to the plumbing equipment field, relates to the equipment that water float thing and other foreign material are also pulled in a kind of interception clearly out, refers to the grid sewage-removing machine structure especially.
Background technology
Grid sewage-removing machine plays a part interception and pulls water float thing and other foreign material clearly out as a kind of plumbing equipment.The grid sewage-removing machine kind of using is more at present, wherein divides according to the grizzly bar gap width, can be divided into carse, medium and small three types grid sewage-removing machine, is respectively applied for floating thing and other foreign material that certain size in the water is also pulled in interception clearly out.
Under the certain condition of flow, the grizzly bar gap is more little, and the size that can tackle foreign material is more little, increases but grizzly bar quantity is corresponding, and the equipment overall width increases; Simultaneously, the grizzly bar gap is more little, and it is also big more that water flows through the grid head loss.Thereby cause cost of equipment and running cost to increase, and floor space increases.On the contrary, under the certain condition of flow, as increasing the grizzly bar gap, the equipment overall width can reduce, and it is also more little that water flows through the grid head loss, thereby reduces cost of equipment, running cost and take up an area of requirement, but differs after increasing and satisfy the interception requirement surely in the grizzly bar gap.Therefore, the grid sewage-removing machine determined of grizzly bar gap often only is applicable to an operating mode, certain flow and certain interception foreign material size.
In practice, there are the two or more operating modes that need reply:
For example in combined drainage system, the grid sewage-removing machine of system's pumping plant need satisfy two kinds of operating modes: 1.. and in the time of fine, what enter pumping plant mainly is dry flow sewage, and the water yield is little, pipeline degree of filling little (depth of water is more shallow in the pipeline).In this case, the grizzly bar height of pumping plant grid does not need too high (because the depth of water is more shallow), (this is because interval of grid strip generally depends on the water pump bore to the dimensional requirement height of grid interception foreign material, fine pumping station operation foul water pump, foul water pump bore less (rainwater pump relatively), the foreign material size can not surpass certain size in the requirement water, otherwise foul water pump damages easily.), the grid gap is little, is generally 10～25 millimeter.2.. the rainy day, what enter pumping plant is rainwater and sewage, flow is big, the pipeline degree of filling is big, and (depth of water is darker in the pipeline, situation much larger than dry days), low relatively (this is because interval of grid strip generally depends on the water pump bore, rainy day pumping station operation rainwater pump to grid interception foreign material dimensional requirement, the foreign material size can not surpass certain size in the rainwater pump requirement water, otherwise the rainwater pump damages easily.In the same pumping plant because the bore of rainwater pump is generally much larger than foul water pump, thereby to the dimensional requirement of foreign material in the water will be low many), the grid gap is big, is generally 40～80 millimeter.
For solving above similar problem, as grid sewage-removing machine being set, perhaps adopt two covers (or many covers) grid sewage-removing machine by worst condition (Peak Flow Rate, the thinnest grid spacing), all can increase equipment investment, increase operational and administrative expenses and site requirements.
The utility model content
The purpose of this utility model is to provide a kind of improved grid sewage-removing machine structure, can serve two or more working condition requirements, enlarges its scope of application.
For achieving the above object, solution of the present utility model is:
A kind of improved grid sewage-removing machine structure comprises grid, it is characterized in that: this grid comprises first grid and second grid, and this first grid is arranged at bottom, the time of filtration with first kind of specification; Second grid is arranged on first grid, has the time of filtration of second kind of specification.
Further, first grid and second grid all adopt the grizzly bar structure.Or,
First grid and second grid all adopt wire-grid structure.Or,
First grid adopts the grizzly bar structure, and second grid all adopts wire-grid structure.Or,
First grid adopts wire-grid structure, and second grid adopts the grizzly bar structure.
Also comprise the 3rd grid, it is arranged on second grid, and the 3rd grid has the time of filtration of the third specification.
The 3rd grid can adopt grizzly bar structure or wire-grid structure.
First grid and second grid can also adopt other structures that can reach the object of the invention.
The utility model improves the grid of conventional grid spotter, and interval of grid strip in the certain altitude of its bottom (being that grid is erect the bottom, back) is encrypted, and becomes fine fack, thereby satisfies the little water yield and tackle demanding situation; Fine fack with top still be in or coarse rack, after the water yield increases, and does not have fine fack, enable thick or middle grid, require low situation to satisfy the big and interception of the water yield.The cell structure of the same grid sewage-removing machine of the utility model comprises various ways, and time of filtration also can be provided with multiple according to actual conditions, and the height of every kind of grid requires to determine according to the water yield, has realized that the separate unit grid has the ability of service various working.
Owing to adopt such scheme, grid sewage-removing machine of the present utility model is integrated thick, fine fack, the grizzly bar gap that has different size with a grid, can serve two or more working condition requirements, the scope of application obtains enlarging, can effectively reduce equipment and reduce occupation area of equipment, to reach most economical rational purpose.
Description of drawings
Fig. 1 be a kind of embodiment of the utility model the cell structure schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
As shown in Figure 1, be the grizzly bar part of the grid sewage-removing machine after improvement of the utility model, after upright the installation, its bottom is highly to be first grid of H1, and it adopts the time of filtration of first kind of specification, i.e. interval of grid strip h1; Highly be arranged on first grid for H2 second grid, it adopts the time of filtration of second kind of specification, i.e. interval of grid strip h2.
The fine fack part, interval of grid strip h1 is less, and is little and tackle demanding situation to satisfy the water yield, and the depth of immersion of its height H 1 during according to the little water yield determined.Its top is the coarse rack part, and interval of grid strip h2 is bigger, tackles the low situation that requires greatly to satisfy the water yield, and the overall height of H2+H1 is determined according to the condition of flooding of big yield.
