Abstract
The utility model discloses a channel grinding type bar screen. The bar screen comprises a channel type bar screen framework. An arc-shaped overflow bar screen provided with at least one overflow groove is arranged in the bar screen framework. One end of the arc-shaped overflow bar screen is fixed at the water inlet end of the bar screen framework, the other end is fixed at the water outlet end of the bar screen framework, and the raised arc surface is directed to the water inlet end of the bar screen framework. A rotating scraper capable of being engaged with the overflow groove during the rotating is arranged in the bar screen framework at the water outlet end of the overflow bar screen, and the water outlet end of the bar screen framework is provided with a grinder. The adoption of the fixed type arc-shaped overflow bar screen largely increases bar screen rigidity, effectively resists current impact and increases the quantity of sewage passing through. Meanwhile, the rotating scraper is precisely engaged with the bar screen, solid impurities trapped on the upstream surface of the fixed bar screen can be cleared, and the solid impurities trapped are ground by the grinder to pass through.
Description
Technical field
The utility model relates to a kind of sewage disposal device, particularly a kind of equipment of be used for disposing of sewage solid impurity and suspended substance.
Background technology
The tradition grid is made up of metal grizzly bar and framework that one group (or many groups) parallels, tilt to be installed in the into channel of water, or the ingress of water inlet pumping plant pump well, with bigger suspended substance and impurity in the interception sewage, guarantee the works better of subsequent disposal structures or equipment, and crush type grid is a kind of grid in order to comminuted suspension impurity that disintegrating apparatus also is set in grid.Crush type grid mainly contains following two kinds at present:
One, rotary drum crush type grid, this grid are that present crush type grid is used more equipment.Continuously the hollow rotary drum of rotation is with being tackled and making it to flow into the downstream crusher than bigger material and pulverized in the sewage in this equipment utilization, and sewage then flows through hollow rotary drum by the netted space on the hollow rotatory drum wall, reaches the requirement that increases water amount.Because the restriction that drum structure is required by rigidity and impact strength, the diameter of this equipment rotary drum and rotary drum height also all are restricted, thereby water amount is restricted; Because hollow rotary drum is a wholecircle type structure, and current flow through rotatory drum wall twice, have increased head loss, therefore, it is only applicable to the occasion of intermediate flow simultaneously.
Two, plate-spinning formula crush type grid, this grid is made of a plurality of rotating shafts.Rotating compact disc all is housed, with corresponding rotating shaft formation filtering surface in each rotating shaft.By rotating shaft rotation, form transmission action slowly, make solids cross grid surface and be sent to discharge point, water flows through between the rotating compact disc.First with last rotating shaft on independently double-edged fine-toothed comb is housed, the solid sundries of blocking is discharged back main stem or dirt colleceting area.Though this equipment can increase the flow by water by the method that increases rotating shaft quantity, complex structure, amount of parts is various, and equipment cost is higher, and is simultaneously difficult in maintenance.
The utility model content
In order to solve the above problems, the purpose of this utility model be to provide a kind of simple in structure, flow is by sewage greatly, and the grid maker that solid impurity in the sewage and suspended substance are effectively tackled and pulverized.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of channel crushing type grilling machine, the grid framework that comprises channeltype, be equipped with in the described grid framework and be circular arc and have the water grid excessively that at least one crosses tank, the end that described circular arc is crossed the water grid is fixed on the feed-water end of grid framework, the other end is fixed on the water side of grid framework, and its convex globoidal is towards the feed-water end of grid framework, the water outlet side that was positioned at the water grid in the described grid framework is provided with the revolving scraper that can be meshed with the mistake tank when rotating, and also is provided with the pulverizer that is positioned at trash rack convex arc bottom side solid impurity junction in the described grid framework.
As improvement of the technical scheme, the described water grid of crossing has two, is symmetricly set in the grid framework, and described pulverizer is crossed between the sewage junction of water grid convex arc bottom side symmetrically arranged.
As further improvement in the technical proposal, the described circular arc of crossing the water grid is 1/4 full circle.
As further improvement in the technical proposal, the channel cross-section of described channeltype grid framework is rectangular or square.
As further improvement in the technical proposal, described pulverizer freely is plugged in the grid framework.
As further improvement in the technical proposal, described pulverizer is the twin shaft pulverizer.
The beneficial effects of the utility model are: the utility model adopts fixed circular arc type to cross the water cell structure, and grid rigidity greatly strengthens, and effectively resists the impact of current, can pass through big flow sewage; The accurate engagement of the revolving scraper device of grid back and grid simultaneously, can farthest remove the solid sundries that is trapped within on fixing the water grid upstream face, the solid impurity of holding back is pulverized via pulverizer and is passed through, and keeps the grid cleaning, has characteristics simple in structure, that water amount is big.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural representation;
Fig. 2 is another example structure synoptic diagram of the utility model;
Fig. 3 is that the utility model is crossed water grid synoptic diagram.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model is a kind of channel crushing type grilling machine, the grid framework 1 that comprises channel-type, be equipped with in the described grid framework 1 and be circular arc and have the water grid 2 excessively that at least one crosses tank 21, the end that described circular arc is crossed water grid 2 is fixed on the feed-water end of grid framework 1, the other end is fixed on the water side of grid framework 1, and its convex globoidal is towards the feed-water end of grid framework 1, the water outlet side that was positioned at water grid 2 in the described grid framework 1 is provided with the revolving scraper 3 that can be meshed with mistake tank 21 when rotating, and described grid framework 1 channel bottom also is provided with the pulverizer 4 that is positioned at trash rack 2 convex arc bottom side solid impurity junctions.The utility model adopts fixed circular arc type to cross the water cell structure, and grid rigidity greatly strengthens, and effectively resists the impact of current, can pass through big flow sewage; The accurate engagement of the revolving scraper device of grid back and grid simultaneously, can farthest remove the solid sundries that is trapped within on the stationary grizzly upstream face, the solid impurity of holding back is pulverized via pulverizer and is passed through, and keeps the grid cleaning, has characteristics simple in structure, that water amount is big.
