Abstract
Disclosed is a rotary water decanter, comprising a driving device which is connected with a transmission device, one end thereof is connected with the transmission device, the other end thereof is hinged with a water decanting pipe group on a pool support, and a control system which controls the operation of the driving device. Wherein the control system comprises a stroke sensor and a field control box. The transmission device comprises a drum and a flexible rope band thereon. The water decanting pipe group comprises water decanting pipes which are communicated with each other, at lease one drainage branch pipe and a water outlet pipe. A row of water inlet holes are arranged at the bottom of the water decanting pipe. Because a flexible hoisting transmission device is used, the occupied floor space is small, the transmission efficiency is high.

Embodiment
The lower end of flexible drawing rope band 5 with strain the interface of hydrophone all the time more than the water surface.
For lubrication and seal assembly under water, first aqueduct 6 and second aqueduct 11 that lubrication and seal is used also are set, described aqueduct one end connects strains water pipe, and the other end is connected in the lubrication and seal pipeline of described pond rotation supporting tube (with the pipe that cooperates in big bearing pack 14 and the tail bearing group 10).Described assembly under water is shown in Fig. 3,4, comprise the big supporting tube group 8 that is arranged on an end above the rising pipe 9, be arranged on the big bearing pack 14 that the pond is supported, by the connection sealing plate group 17 of O RunddichtringO 19 movable sealings connection water shoot coupling flange 18, and the clip group 15 that has tightened the P RunddichtringO 16 of the first road sealing function.Be arranged on tail ends above the rising pipe 9 tail bearing group 10, reached second aqueduct 11.
Water inlet is stable in order to keep, equilibrium air pressure, at the described water pipe of straining ventilating pit is set.
The utility model principle of work: the motor direct connection step-down gear in the drive unit will rotatablely move and pass to two reel groups synchronously, and traction is strained the tube hub line that water pipe, aqueduct, central drainage pipe, PO combination sealing lay out water pipe group 9 and rotated.The closed loop control system that field control case 20 and stroke sensor 4 are formed; according to program timely adjustment speed of rotation and the direction set; be achieved as follows action: drive unit 1 drives reel 3 according to speed of setting and direction rotation; by flexible strip 5 (steel band or wireline) folding and unfolding clocklike; traction is strained hydrophone and is rotatablely moved up and down; make and strain water pipe group 12 fast near the water surface, speed stabilizing descends and evenly strains the actuation cycle of water, quick return, shutdown wait.Receive when the field control case and to strain water when instruction, frequency transformer output power frequency supply, strain water pipe group 12 rotary components and under deadweight, counterweight and the effect of flexible piece tractive force, at the uniform velocity drop to the water surface with fast speeds from the starting position, top, then frequency transformer output is with the low-frequency power of corner variation, its tube hub descended with slower even vertical component speed by processing requirement when assurance was strained water pipe and is rotated down, allow supernatant liquor conflux to enter and strain the water pipe group and flow to big supporting tube by four decline arms, rising pipe group again and discharge outside the pond, finish and evenly strain water from a plurality of perforate annulus in below.In straining the water process, strain the water pipe group scum silica frost is kept off at the water surface simultaneously.Following when straining water level and putting when what strain that hydrophone arrive to set, stroke sensor sends signal control and strains hydrophone and stop, then frequency transformer automatically switches to the power frequency form, and the flexible piece drive is strained water pipe and is returned to starting position (being higher than the water surface) fast, waits for and finishes next circulation.
Prior art compares, and characteristics of the present utility model are:
1) replacing nut-screw rod transmission (self-locking) with the rolling wheel Flexible Transmission passes to the output of motor-speed reducer and strains the hydrophone rotational structure. Transmission efficiency rises to more than 0.95 by 0.3～0.4. Drive unit directly is fixed on Chi Ding ground, need not make somebody a mere figurehead, and compact conformation, driving member are all on the water.
2) strain the water pipe group with circular cross-section and replace upper shed strip weir notch, it is long-pending constant to strain the water pipe water flow section when the anglec of rotation changes, closed-loop control is strained water pipe and is evenly descended with the water speed of straining of technological requirement, and inside and outside liquid level difference is constant in the pipe, thereby it is even to guarantee to strain discharge. Adopt the pipe of nominal outer diameter to make, tubing is by the compression molding of pipe fitting factory, and processability of product structure is good, stability and good rigidly. Straining has minority passage pipe on the water pipe, divide into perforate annulus undercurrent polywater, and entry buoyancy is much smaller than gravity. Difficult scum silica frost is blown into of stormy waves strained in the water pipe, and stormy waves is little to straining the discharge impact.
3) the two O RunddichtringOs of sealing+exterior end face hydraulic pressure self-tightening sealing P type circle Assembled rotary hermetically-sealed construction in the decrement is decided in employing. Supernatant after the filtration is communicated with sealing surface, has improved sealing property in lubricated. Be called for short the sealing of self-lubricating PO Orthogonal Composite. Operating mode is good under the protection that the O RunddichtringO is lubricated at supernatant and the P type seals, long service life. The P type self-tightening sealing that supernatant is lubricated, sealing is reliable, and it is convenient to change.
4) adopt monomer casting MC nylon to make bearing under water, it is low to have coefficient of friction under the supernatant after the filtration is lubricated, and fatigue strength height, wearability are good, long service life.
5) closed-loop control system that adopts stroke sensor and PLC+ frequency converter to form can be strained as required discharge and be realized evenly straining water.
