Abstract
A novel device capable of preventing filter materials in a filter tank from running away comprises a water inlet and outlet weir groove, two pieces of upper sand prevention wing plates arranged in front of the water inlet and outlet weir groove, lower sand prevention wing plates arranged on two sides of the water inlet and outlet weir groove and two pieces of water inlet and outlet weir plates, one ends of the water inlet and outlet weir plates are fixed on the upper sand prevention wing plates, and the other ends of the water inlet and outlet weir plates are fixed on the water inlet and outlet weir groove. When the filter tank is in a back washing stage, the upper sand prevention wing plates and the lower sand prevention wing plates of the novel device can effectively prevent the filter materials in the filter tank from running away from the water inlet and outlet weir groove, when the back washing stage is finished, the upper sand prevention wing plates and the lower sand prevention wing plates can prevent the filter materials which exceed height of the water inlet and outlet weir groove from gathering on the upper portion of the sand prevention wing plates and enable the filter materials to return to the filter tank completely, so that a problem that the filter materials run away from the water inlet and outlet weir groove is solved.
Description
Technical field
The utility model relates to municipal water supply, draining and environmental pollution by water and administers the field, relates in particular to a kind of novel device that prevents that the filter tank filtrate runs off.
Background technology
The effort of sewage disposal nearly decades in China city, coverage rate has reached about 80%, and according to incompletely statistics, the whole nation has about 2200 of sewage treatment plant, and various water treatment facilities arise at the historic moment.
Present most of water treatment facilities ubiquity a large amount of phenomenons that run off of filtrate, has a strong impact on wastewater treatment efficiency.
The utility model content
In order to overcome the deficiency of technique scheme, the purpose of this utility model provides the new device that a kind of simple in structure, anti-filtrate runs off.
This patent is realized by following technical solution:
A kind of novel device that prevents that the filter tank filtrate runs off, comprise the Inlet and outlet water weir notch, go up the sand control wing plate for two that are installed on Inlet and outlet water weir notch the place ahead, be installed on the following sand control wing plate of Inlet and outlet water weir notch both sides, an end is fixed on the sand control wing plate, the other end is fixed on two Inlet and outlet water weir plates on the Inlet and outlet water weir notch.
The described novel device that prevents that the filter tank filtrate runs off of this patent, its operation principle is: during the stage, water enters the filter tank by the Inlet and outlet water weir notch from overflow between the Inlet and outlet water weir plate at filter; Carry out backwash during the stage in the filter tank, the last sand control wing plate of this device and following sand control wing plate can effectively stop the filtrate in the filter tank to run off from the Inlet and outlet water weir notch, the backwash stage surpasses the filtrate of Inlet and outlet water weir notch height when the backwash stage finishes simultaneously, last sand control wing plate and following sand control wing plate can also make filtrate can not be enriched in sand control wing plate top, get back in the filter tank fully.
Its advantage is: can fundamentally solve the problem that filtrate runs off from the Inlet and outlet water weir notch.
Description of drawings
Reaching embodiment below with reference to the accompanying drawings is described further this patent:
Fig. 1 is a this patent overall structure schematic diagram
Among the figure: 1, Inlet and outlet water weir notch; 2, go up the sand control wing plate; 3, following sand control wing plate; 4, Inlet and outlet water weir plate; 5, filter tank.
The specific embodiment
As shown in Figure 1, a kind of novel device that prevents that the filter tank filtrate runs off, comprise Inlet and outlet water weir notch 1, go up sand control wing plate 2 for two that are installed on Inlet and outlet water weir notch the place ahead, following sand control wing plate 3, one ends that are installed on Inlet and outlet water weir notch both sides are fixed on the sand control wing plate 2, the other end is fixed on two Inlet and outlet water weir plates 4 on the Inlet and outlet water weir notch 1.
The described novel device that prevents that the filter tank filtrate runs off of this patent, its operation principle is: 5 when being in filtration stage in the filter tank, and water enters filter tank 5 by Inlet and outlet water weir notch 1 from 4 overflows of Inlet and outlet water weir plate; 5 are in backwash during the stage in the filter tank, the last sand control wing plate 2 and the following sand control wing plate 3 of this device can effectively stop the filtrate in the filter tank 5 to run off from Inlet and outlet water weir notch 1, the backwash stage surpasses the filtrate of Inlet and outlet water weir notch 1 height when the backwash stage finishes simultaneously, last sand control wing plate 2 and following sand control wing plate 3 can also make filtrate can not be enriched in sand control wing plate top, get back to fully in the filter tank 5.
Its advantage is: can fundamentally solve the problem that filtrate runs off from the Inlet and outlet water weir notch.
Person skilled in the art should be familiar with, the above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, variation, modification that the foregoing description is done all will drop in the claim scope of the present utility model.
