In the prior art; Sucker in the cleaning device of fibre turntable filter is close to the side of filter disc through sucker fixing, and sucker and filter disc are in surface contact state, the sucker fixed angle; Can not regulate; Simultaneously, also there are difference in various degree in whole device and civil engineering pond body compatible degree structurally, thereby the integral suction device after causing installing can't make sucker and filter disc keep the aspiration phases of coordinating most; Strengthened stretching inevitably, and then very easily filter cloth has been caused influences such as cutting and damage filter cloth.
The utility model content
The purpose of the utility model is; Problem to the prior art existence; A kind of rolling backwash device that is used on the outer water inlet fibre turntable filter is provided, makes sucker when work, be in the optimum Working of mutual coordination with filter disc, minimizing is to the influence of filter cloth; Reduce operating cost, the equipment work of making gets a promotion.
The technical scheme that the utility model is dealt with problems is: a kind of rolling backwash device that is used on the outer water inlet fibre turntable filter is provided; Comprise interconnective filter disc, filter disc support, filter cloth, sucker, sucker fixing; Wherein, said sucker is the rolling sucker, and its quantity is two; Between said rolling sucker, the compression spring is set, said rolling sucker is adjacent to said filter disc through said sucker fixing.
Further, said sucker fixing comprises interconnective fixing spring and sucker fixed axis.
Further, said rolling sucker comprises gyroaxis, roller post, and wherein, said gyroaxis is arranged on the both sides of said rolling sucker, and said roller post is connected with said filter disc.
Further, said gyroaxis is fixedly connected through holding screw, revolution catch.
Further, said roller post interconnects, and is fixed on the aqua storage tank that sets out water pipe through holding screw with fixed block, revolution axostylus axostyle, sealing plate, sealing clamp successively.
The setting of said gyroaxis and said compression spring, make the rolling sucker with can adjust the suction angle voluntarily after filter disc contacts, thereby make the rolling sucker be in best suction operation state.
Said two roller posts are connected with filter disc; And the suction inlet of formation filter disc; Making rolling sucker and filter disc when backwash is worked, carry out linearity rolls relatively; Thereby make the sewage of in filter disc, releasing in suction aqua storage tank between two roller posts, and discharge through outlet pipe, whole aspiration procedure does not produce influences such as stretching to the filter cloth on the filter.
Compared with prior art, the beneficial effect of the utility model is:
1, the utility model novel structure is reasonable in design, and equipment is stablized corrosion-resistant, and overall weight is light, is convenient to install and maintenance, and can regulates the cleaning angle automatically, can make sucker and filter disc coordinate each other and clean with the suction operation state of the best;
2, the utility model has effectively increased the service life of filter cloth, has correspondingly reduced operating cost, thereby the macroeconomic cost of filter plant is reduced greatly, is suitable in fibre turntable filter and relative mechanical equipment technical field, applying.

The specific embodiment
In order to make persons skilled in the art can know the technology of understanding the utility model, combine accompanying drawing that the utility model is done further explanation at present.
Extremely shown in Figure 3 like Fig. 1; A kind of rolling backwash device that is used on the outer water inlet fibre turntable filter; Comprise interconnective filter disc (not shown), filter disc support 1, fiber filter cloth 2, sucker fixing 3, two rolling suckers 4, compression spring 5; Between two rolling suckers 4, be compression spring 5, rolling sucker 4 is adjacent to said filter disc (not shown) through sucker fixing 3; Said sucker fixing 3 comprises interconnective fixing spring 3-1 and sucker fixed axis 3-2; Said gyroaxis 4-3 is arranged on the both sides of said rolling sucker 4, and said roller post 4-8 is connected with said filter disc (not shown); Said gyroaxis 4-3 is fixedly connected through holding screw 4-1, revolution catch 4-2; Said roller post 4-8 interconnects, and is fixed on the aqua storage tank 4-10 that sets out water pipe 4-11 through holding screw 4-9 with fixed block 4-7, revolution axostylus axostyle 4-6, sealing plate 4-5, sealing clamp 4-4 successively.
Said gyroaxis 4-3 and said compression spring 5 make rolling sucker 4 with can adjust the suction angle voluntarily after the filter disc (not shown) contacts, thereby make rolling sucker 4 be in best suction operation state.
Said two roller post 4-8 are connected with the filter disc (not shown), and form the suction inlet of filter disc (not shown), make rolling sucker 4 and filter disc (not shown) when backwash is worked, carry out linearity and roll relatively.
Use the utility model in sewage treatment plant, secondary effluent after treatment flows into the filter tank, after filtering through fiber filter cloth 2; Filtrating is collected through hollow tube, discharges the filter tank through overflow launder again, along with the accumulation of mud on the fiber filter cloth 2; Fiber filter cloth 2 filtration resistances increase, and the filter tank water level raises gradually, when the liquid level difference of filtrating reaches setting value; Start backwashing pump, the beginning backwash operation.At this moment; The filter disc (not shown) begins rotation under the drive of drive motors, rolling sucker 4 is under the support of sucker fixing 3, and the spring 3-1 that is fixed evenly separates; Each rolling sucker 4 is that angle is adjusted at the center automatically with gyroaxis 4-6 again, begins fiber filter cloth 2 is cleaned.In this process; 5 pairs two continuous rolling suckers 4 of compression spring compress; Make it to keep the co-ordination state that parallels with the filter disc (not shown), two roller post 4-8 then carry out linear relative motion with fiber filter cloth 2, thereby make the sewage of in the filter disc (not shown), releasing from sucking between two roller post 4-8 in the aqua storage tank 4-10; And through outlet pipe 4-11 discharge, whole suck purge process does not produce damaging influences such as any stretching to the fiber filter cloth on the filter 2.
The above-mentioned rollers post is processed by the PVC material.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art made to any conspicuous improvement of above-mentioned embodiment or change, can not exceed the design of the utility model and the protection domain of accompanying claims.
