Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the utility model easy to understand, the utility model is further described with reference to the figures and the specific embodiments.

As shown in fig. 1, 2, 3 and 4, the technical solution adopted by the present invention to solve the technical problem is: the utility model provides a novel week is advanced all around and is gone out rectangle sedimentation tank skimming pipe, includes the pool wall, installs skimming pipe 100 between the pool wall, and the equal cover in the surface at skimming pipe 100 both ends is equipped with arc 130, and arc 130 outwards stretches out, is fixed with the support frame 150 towards the arc on the pool wall, installs the slag trap 140 of adjustable length on the support frame 150, closely laminates between slag trap 140 and the arc 130.

In addition, the arc plates 130 at the two ends of the skimming tube 100 are symmetrically arranged, the extending height of the arc plates 130 is 100mm, and the overlaying depth between the slag baffle 140 and the arc plates 130 is 50 mm.

45 is arranged between the supporting frame 150 and the pool wall⁰The angle is arranged, support frame 150 is fixed in the pool wall through expansion bolts 160, support frame 150's shape is L shape, the surface of support frame 150 and the surface of slag trap 140 all are provided with waist shape hole, the downthehole screw that installs of waist shape, the length in waist shape hole is 30mm, waist shape hole through adjusting coincidence between support frame and the slag trap, adjust the length that stretches out of slag trap, the regulation size of slag trap is 30mm, the slag trap can be adjusted in a flexible way and the interval of skimming pipe, avoid the dross baffle to contact with the skimming pipe, cause electronic skimming pipe operation card to hinder.

The arc-shaped plate 130, the slag baffle 140 and the support frame 150 are all made of stainless steel 304, have the thickness of 4mm, and are fastened and durable.

The skimming pipe 100 is of a tubular structure, a weir port for collecting floaters is arranged on the skimming pipe 100, the skimming pipe 100 is connected with an electric actuating mechanism 110 through a transmission mechanism, the transmission mechanism adopts a worm gear, bearings and bearing seats 120 which are matched with each other are respectively arranged at two ends of the skimming pipe 100, and the bearing seats 120 are fixedly connected with the wall of the pool.

The slag skimming device comprises a slag skimming pipe, an arc-shaped plate and a slag baffle support frame, wherein the arc-shaped plate is arranged on the slag skimming pipe, and the height of the arc-shaped plate is 100 mm; the slag trap is installed on the support frame, and the support frame is fixed on the lateral pool wall. Start electric actuator through the operation, with the rotatory certain angle of skimming pipe face to sedimentation tank surface floater orientation, the skimming pipe is gone up the weir mouth and when rotatory to the skimming position with the fixed arc of skimming pipe, can carry out liquid level skimming work, and the slag trap is hugged closely on the arc, and the wainscot overlap the degree of depth and be 50mm, is bolted connection between arc and the skimming pipe, and the size is controlled about adjustable arc, guarantees closely to laminate with adjustable slag trap, and the binding face is the hourglass sediment. When the liquid level scum mixed water flow flows through the area of the support frame, the liquid level scum mixed water flow is driven into the scum pipe through the inclined plate with the angle of 45 degrees on the support frame and is discharged through the scum pipe. After the floating objects are discharged, the electric actuating mechanism is started again, the slag skimming pipe is rotated reversely to return to the initial position, the lower edge of the weir crest is higher than the liquid level, and slag discharge is stopped.

The slag-stopping plate is added on the basis of the conventional electric slag-removing pipe, has the function of guiding liquid level water flow to enter the slag-removing weir crest, not only ensures that no dead zone is left at the two ends of the slag-removing pipe, but also ensures that liquid level scum is cleaned up and no scum is left at the two ends, and solves the problem of pain in actual operation.
