Description

Rotary-type water decanter

The utility model relates to a kind of sewage discharge equipment, especially a kind of rotary-type water decanter, and it is applicable to various intermittent circulating active sludge method Sewage treatment systemss, the supernatant water after handling can be drained with rotation mode from top to bottom from the surface simultaneously.

Along with science and technology development, protection environment, improvement sewage, rational utilization of water resources are the problems that the world faces, and China has also strengthened the dynamics of waste water control in recent years.At present at home and abroad in the sewage treatment process, generally all use a kind of equipment that the clear water of post precipitation can be drained from the surface from top to bottom---strain hydrophone, and use in the domestic sewage treatment process strain wetting system mostly from import, the equipment cost height, maintenance is also inconvenient.At this situation, designer of the present invention according to actual needs in the past few years, develop the hydrophone of straining of multiple different structure, and all obtained Chinese patent, 1., ZL99237253.4 its patent No. and title are respectively:, 2., ZL99245559.6 telescoping tube type decanter:, the adjustable and retractable tubular type is strained hydrophone; 3., ZL99245322.4, the adjustable hydrophone of straining; 4., ZL99237987.3, small-sized wall-hanging the adjusting strained hydrophone.These several water heater structure differences of straining, characteristics are different, but in actual use, there is a common defective, promptly strain hydrophone and can only receive water at point of fixity (mounting points position), in horizontal plane, can not rotate, and the sewage disposal pool area is bigger, sewage aeration postprecipitation process is carried out from top to bottom, the water quality of same aspect is basic identical, therefore, it should be that into the water head will drain with rotation mode from top to bottom fast than the clear water on upper strata that ideal is strained wetting system, improves the efficient of discharging clear water.

The hydrophone of straining that the purpose of this utility model is designed at existing problem in the above-mentioned prior art just with rotation receipts water function, this is strained hydrophone and not only has the above-mentioned function that hydrophone drains clear water from top to bottom of straining, and design more science, structure is more reasonable.

The purpose of this utility model is to realize by following scheme: originally strain hydrophone and comprise keg float, the water inlet head that is connected with keg float and the expansion pipe and the drain elbow that are connected the below of water head into, offer the receipts mouth of a river on the water inlet head by gate control, the drain elbow lower end is connected with the upright bucket of draining and can rotates relative to the upright bucket of draining on joint face, the upright bucket of draining center installs an affixed rotating shaft, on the drain box that the upright bucket seat of draining is placed on wall pipe is communicated with, wall pipe is provided with water discharge valve, rotating shaft can make its drive system of back and forth rotating combine by the affixed power wheel and in its top, and the rotating shaft lower end is supported in the bearing axis hole that is fixed on the drain box.

In the utility model, the water inlet system of being made up of keg float, water inlet head, expansion pipe, drain elbow is two groups, and drain elbow lower end symmetry is connected the upright bucket of draining both sides; The upright bucket of draining bottom have one with the Y shape support of the upright bucket bucket of draining wall Joint, carriage center and rotating shaft are fixed together; The both sides of water inlet head all offer the receipts mouth of a river by gate control, and stage clip is connected between two gates can oppress closing gate when stopping draining; The bending degree of described drain elbow is 90 °; The bearing that is fixed on the drain box is a Y shape bearing.Keg float is a cylindrical structural.

Drive system of the present utility model is that the tooth bar, worm screw, the power wheel that link together by two groups of cylinders into and out of air valve control, piston, with piston constitute jointly, this drive system is set in place in the transmission case of a sealing of the upright bucket of draining top, and transmission case is fixed on the drain box by column; Being used for the reciprocating mechanism of accessory drive is the travel switch that is installed in the transmission case.

Drainage principle of the present utility model is: because keg float is the container of sealing, produce buoyancy upwards, under the keg float buoyancy, the receipts mouth of a river of unsteady water inlet head remains at horizontal plane below certain distance, and drain shut valve during not draining has the water that retains in the drain elbow, pipe internal pressure and pipe external pressure balance, gate is closed under the stage clip effect, and when Dang Chizhong carried out aeration, sewage can not enter in the water shoot.When the needs draining, water discharge valve is opened, the water that water shoot retains is discharged, in the pipe with the outer pressure reduction that forms of pipe, gate under differential pressure action, the spring pressurized, two gates are opened, begin draining, unsteady water inlet head descends with the water surface, and clear water flows to expansion pipe to drain elbow, draining by the narrow and long rectangular receipts mouth of a river and founds bucket, drain box, wall pipe outside discharging the pond.During draining, water level descends gradually, and drain elbow and expansion pipe and horizontal plane angle are more and more littler, because the buoyancy and the expansion pipe flexibility characteristics of keg float, all the time make into that the receipts mouth of a river of water head remains on level attitude substantially, each is received mouth of a river and remains on same aspect substantially and receive water.

Rotation principle of the present utility model is as follows: when air inlet magnetic valve A opens, exhaust solenoid valve B closes, air inlet magnetic valve C opens, exhaust solenoid valve D closes, air chamber I in the cylinder begins inflation, piston drives tooth bar moving linearly forward, tooth bar rotates by the gear driven worm screw on the worm screw, worm screw is meshed with power wheel on being fixed in rotating shaft, thereby driving rotating shaft rotates, because the upright bucket of draining is to be fixed together with rotating shaft, therefore upright bucket turns clockwise around O-O axle (shown in Figure 1), when tooth bar touches travel switch forward, Controlling System (not belonging to this patent scope) is closed air inlet magnetic valve A, exhaust solenoid valve B opens, air inlet magnetic valve C opens, and exhaust solenoid valve D closes, and the pressurized air in the air chamber I is discharged by exhaust solenoid valve B, begin inflation in the air chamber II, piston drives tooth bar and moves backward, and by above-mentioned transmission system upright bucket is counterclockwise rotated, when tooth bar touches the other end travel switch, air inlet magnetic valve A opens, exhaust solenoid valve B closes, and air inlet magnetic valve C closes, and exhaust solenoid valve D opens, pressurized air in the air chamber II is discharged by exhaust solenoid valve D, begins inflation in the air chamber I.Reciprocation cycle during draining, the water inlet head that floats simultaneously carries out crankmotion at horizontal plane.

The utility model in use, water exhaust system and rotating mechanism move simultaneously.When not draining, because the self-locking characteristics of worm screw and transmitting gear are carried out aeration or keg float and carried under the effect at water surface wind in the pond, the water inlet head that floats also is unlikely to any swing.

Originally straining the advantage that hydrophone compared with prior art possesses is: not only have and above-mentionedly existingly strain the effect that hydrophone drains clear water from top to bottom, and increased spinfunction, can make the very fast discharge of clear water of same aspect, draining is more scientific and reasonable.
