Abstract

The utility model relates to an unpowered automatic floating type water decanter, relating to a device which is installed in a sewage treatment desilter, is used for eliminating supernatant liquid and is composed of a lifting guiding rail, a floating box, a horizontal weir opening, a liquid drainage main pipe and a liquid drainage branch pipe. In the utility model, the floating box is sheathed and penetrated on the lifting guiding rail by sleeve lugs on botj sides and can float from top to bottom along the lifting guiding rail; the horizontal weir opening is hung and installed under the floating box and can move from top to bottom following the floating box; the liquid drainage main pipe is installed on the bottom of the desilter and is communicated with a drain pipe; the liquid drainage branch pipe comprises a plurality of rubber corrugated pipes which are ranged in parallel, and both ends of the liquid drainage branch pipe can respectively be communicated with the horizontal weir opening and the liquid drainage main pipe and can flex following the lifting of the floating box.

Description

The unpowered floating type hydrophone of straining automatically

The utility model relates to a kind of equipment that is installed in the sedimentation basin of sewage disposal and is used to get rid of supernatant, particularly relates to a kind of unpowered floating type hydrophone of straining.

In sewage disposal process, need to discharge outside the sedimentation basin through the supernatant that reaches discharge standard behind biochemical reaction and the quiescent setting by certain procedure, straining hydrophone promptly is to be exclusively used in the equipment of getting rid of supernatant.

Though the hydrophone of straining of the prior art has multiple pattern, mostly be must be by the dynamic hydrophone of straining of special power-equipment driving.For example, the rotary-type water decanter that extensively adopts promptly is by drive unit, strains a kind of dynamic hydrophone of straining that parts such as water device and revolution support constitute at present, and it is strained the water device and comprises that mainly weir crest of water decanter, drain branch pipe and discharge opeing are responsible for and can drive the turning down in vertical plane with the variation of pool inner water position by drive unit.When straining water, supernatant is responsible for outside the discharge pond through drain branch pipe and discharge opeing by weir crest of water decanter, when stopping to strain water, needs weir crest of water decanter is returned back to more than the water surface.

Though rotary-type water decanter can utilize the rotary and lifting of weir crest of water decanter and realize straining water, its structural design and actual motion all also exist some that problem to be solved is arranged.At first, the structure of rotary-type water decanter drive unit is quite complicated, it has comprised numerous equipment and parts such as motor, reductor, gear train, turn-screw, connecting rod and secondary support, any one parts malfunctioning all is enough to influence whole operate as normal of straining hydrophone, therefore machining accuracy and the frock precision to each parts all has very high requirement, processing and manufacturing and mounting hardness have been increased greatly, secondly, the revolution of rotary-type water decanter support is made of inside and outside circle and utilizes rubber seal to realize movable sealing.When seal clearance was too small, frictional force was too big, and its running will be very dumb; And seal clearance is when excessive, and the movable sealing performance is very poor again, and long term wear also certainly will be destroyed its sealing.In a word, the sealing that the rotary-type water decanter revolution is supported and the flexibility of running are conflicting, can not take into account.

The purpose of this utility model promptly is to provide a kind of unpowered hydrophone of straining that power-equipment drives that need not, and strain the structure of hydrophone and overcome all puzzlements that bring because of movable sealing to simplify greatly, thereby the steady reliability service of hydrophone is strained in assurance.

To achieve these goals, the utility model utilizes riser guide, buoyancy tank, horizontal crest of weir, the discharge opeing person in charge and drain branch pipe to constitute a kind of unpowered floating type hydrophone of straining automatically.Riser guide comprise vertically be installed in the sedimentation basin about two guide rails; The cover ear muff of buoyancy tank by both sides is through on the guide rail and can fluctuates along guide rail; Horizontal crest of weir is lifted on the below of buoyancy tank by steel band and can moves up and down with buoyancy tank; Discharge opeing is responsible for by fixed support and is fixed on the sedimentation basin bottom and is communicated with pre-buried drainpipe; Drain branch pipe comprises a plurality of rubber bellows that are arranged in parallel, and it is communicated with horizontal crest of weir and drain header respectively and can stretches with the lifting of buoyancy tank in two ends up and down.

When straining water, only need open the valve in the discharge pipe line, the supernatant in the pond can be pooled to that discharge opeing is responsible for and outside drainpipe is discharged the pond through drain branch pipe by horizontal crest of weir.And buoyancy tank swims on the water surface all the time and can make horizontal crest of weir with the variation of pool inner water position automatic lifting, thereby guarantee that straining water normally carries out.Obviously, the utility model drives without any need for power-equipment, and not only structure is simplified greatly, and all puzzlements that can avoid movable sealing to bring, thereby makes the processing and manufacturing and the installation of straining hydrophone simpler and easy, moves also more steady reliable.

Below in conjunction with specific embodiment the unpowered floating type technical characterictic of straining hydrophone automatically of the utility model is described in further detail.

Fig. 1 is the unpowered floating type structural representation of straining hydrophone automatically of the utility model.

With reference to shown in Figure 1, the utility model is unpowered, and the automatic floating type hydrophone of straining mainly is made of riser guide, buoyancy tank, horizontal crest of weir, the discharge opeing person in charge and drain branch pipe.

Riser guide 1 comprises left and right two guide rails that vertically are installed in the sedimentation basin, and cover ear 3 covers of buoyancy tank 2 by both sides are through on the guide rail 1 and can fluctuate at the pool inner water face along guide rail 1.Horizontal crest of weir 4 is lifted on the below of buoyancy tank 2 by steel band and can moves up and down with buoyancy tank 2, and its bottom is provided with leakage fluid dram.Discharge opeing is responsible for 5 and is fixed on the bottom of sedimentation basin and is communicated with pre-buried drainpipe 7 by fixed support 6.Drain branch pipe 8 comprises a plurality of rubber bellows that are arranged in parallel, and it up and down is responsible for 5 with horizontal crest of weir 4 and discharge opeing respectively and is communicated with in two ends, and can fluctuating and stretch with buoyancy tank 2.

During the utility model work, by the electrically operated valve in the control system opening water discharge pipe 7, the supernatant in the pond can steadily flow into drain branch pipe 8 and import discharge opeing along horizontal crest of weir 4 is responsible for 5, is discharged outside the pond by drainpipe 7 at last; When the pond middle water level reached minimum design water level, control system was closed the electrically operated valve in the drainpipe 7 automatically, strained hydrophone and promptly finished one and strain the water process.When refilling sewage in sedimentation basin, buoyancy tank 2 floats the horizontal crest of weir 4 of drive with the rising of water level, and the highest design water level in reaching the pond is so far promptly finished a cyclic process.

In sum as can be known, the utility model is simple in structure, and processing and manufacturing and installation are all very convenient, and it is reliable to operate steadily, and handles the sedimentation basin supernatant so be specially adapted to draining-off sewage.
