Abstract

The utility model discloses an annular decanter which comprises a basic decanter constructed by a power device (4), a lifting device (1), a sealing piece (2) and a fixing baffle (3); the power device (4) and the lifting device (1) are connected; the lifting device (1) and the sealing piece (2) are connected; the sealing piece (2) and the fixing baffle (3) are connected; a water passing channel is arranged on the lifting device (1); when the annular decanter is arranged in a water pool, the upper water in the water pool can be drained from the water passing channel of the lifting device (1) by downwards pushing the lifting device (1), and the drained water is collected and fed to a destination through a flow collector, thus reaching the goal of decanting.

Description

A kind of annular is strained hydrophone

Technical field:

The utility model relates to water treatment and hydrotechnics field, specifically a kind of method and device of straining except that upper water and adjusting water level.As draining weir, the regulation of level in the water conservancy channel of straining in hydrophone, the oxidation ditch sewage treatment technology of serving as in SBR, CASS, the CAST sewage treatment process are controlled weir gate.

Background technology

At present, in water treatment field, the application of SBR, CASS, CAST technology is more and more general, and the drainage pattern of SBR, CASS, CAST processing requirement is for straining the water mode, the most normal employing pontoon type decanting device, rotary-type water decanter, the telescopic hydrophone of straining are strained the water mode for three kinds, strain the water mode for these three kinds and all adopt and strain tank, compile pond water at the middle and upper levels by straining tank, by the adjustable pipe drainage water that its bottom connects, these three kinds of modes all exist following deficiency:

1, strain the tank volume big, take up room big, cost is high, big to the disturbance of water, influences effluent quality;

2, connect the mud of the easy disturbance of the motion lower floor that supports water shoot, influence effluent quality;

3, strain the tank crest of weir and be difficult to the maintenance level, it is inhomogeneous to strain water;

4, the total system complex structure, take up room big, the failure rate of machinery height, maintenance is big;

5, cooperate suitablely in order to ensure evenly to strain between water and each parts, the Installation and Debugging workload is very big;

6, strain hydrophone more than and all be difficult to realize making the water level in water pool constant speed to descend, to reach the purpose of constant current amount draining.

The utility model content

The purpose of this utility model mainly is exactly in order to strain the deficiency of water mode and device more than solving.

To achieve these goals, the technical solution of the utility model is: lifting device, sealing member and fixed dam are formed a basic water device of straining, lifting device and fixed dam all adopt the pipe ring type structure, joining of lifting device and sealing member, sealing member joins with fixed dam again, seal by sealing member between lifting device and the fixed dam, power set links to each other with lifting device, lifting device moves down when needs are strained water, allow the pond median water level surpass the aquaporin of crossing of lifting device, all the time Chi Zhongbiaocengshui is drained by crossing aquaporin.This annular is strained the lifting device (being equivalent to pontoon type decanting device, rotary-type water decanter, the telescopic tank of straining of straining hydrophone) of hydrophone owing to adopt the pipe ring pattern, direction of motion and Chi Zhongshui motion direction are always, when motion, can promote lower layer of water hardly, thereby very little to the disturbance of lower layer of water in the pond and mud, can effectively guarantee water conditioning than water outlet; This annular is strained hydrophone, and it is crossed aquaporin and can adopt ring-like crest of weir pattern, also can adopt the annular orifice pattern, owing to be that annular is crossed the water pattern, occupy little space, cross aquaporin (be equivalent to pontoon type decanting device, rotary-type water decanter, telescopic strain hydrophone strain the tank crest of weir) no matter when equipment making is still installed at the scene, all, strain the water homogeneity thereby improve than being easier to the maintenance level; This annular is strained hydrophone and driven running gear work translational motion up and down by power set, and adjustable-speed, therefore can accomplish that the constant current amount is strained water and adjustable flow constant current amount is strained water, and is very flexible; And pontoon type decanting device, rotary-type water decanter, the telescopic hydrophone of straining are not all accomplished this point; It is very simple that this annular is strained the hydrophone structure, do not have complicated web member and movement parts, and it is little to take up room, and Installation and Debugging are very easy to simple, have fault hardly, can intelligent move, and maintenance is minimum.

Description of drawings:

Fig. 1 is a kind of basic block diagram of the utility model embodiment

Fig. 2 is another basic block diagram of the utility model embodiment

1, lifting device 2, sealing member 3, fixed dam 4, power set

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples:

With Fig. 1 is example, lifting device shown in Fig. 1 (1) is the pipe ring type structure, it is flat-topped weir shape of the mouth as one speaks formula that aquaporin is crossed on top, fixed dam (3) also is the pipe ring type structure, seal by sealing member (2) between lifting device (1) and the fixed dam (3), power set (4) links to each other with lifting device (1), water can not pass through between lifting device (1) and fixed dam (3), when promoting lifting device (1) downwards and make it cross aquaporin weir item and be lower than the pond median water level by power set (4), water just can be discharged from crossing aquaporin, thereby has realized straining the order ground of water.By the rising or falling speed of control lifting device, can realize the purpose that the permanent water yield and the adjustable permanent water yield are strained water easily.Because lifting device (1) is very little with the cross-sectional area of water contact part, and the direction of motion of lifting device (1) when straining water is consistent with the direction of motion of Chi Zhongshui, when moving up and down, its disturbance to Chi Zhongshui and mud is very little, and because there is not other sub aqua sport spare again, very little because of ending total system to the disturbance of water, system is very simple, it is considerably less to take volume, barrier admittedly almost, it is also very simple that this annular is strained the installation of hydrophone, needs the complicated debugging that cooperates, cost also so greatly reduces, thereby has solved the deficiency of present decant method and device existence.

Figure 2 shows that another basic block diagram of the utility model embodiment, Fig. 1 is identical with Fig. 2 principle, form also identically, difference is that lifting device among Fig. 2 (1) is to move up and down in fixed dam (3), and Fig. 1 lifting device (1) is to move up and down in retaining plate (3) periphery.The structure formation of Fig. 2 is littler to the disturbance of water.
