A rotary cylinder of the existing shallow air float tank is dynamically sealed in a labyrinth structure, so components are difficult to process and are easy to deform and clamp. In the utility model, a cylinder soleplate is movably provided with a sealing ring, the rotary cylinder is positioned above the sealing ring, and the outside of a seam between the sealing ring and the rotary cylinder is provided with an elastic sealing ring. The dynamic sealing way is adopted in the rotary cylinder, so the shallow air float tank has the advantages of steady operation, good sealing effect and convenient processing and installation.
Description
The utility model relates to a kind of shallow air-floatation pond, the shallow air-floatation pond of the novel dynamic seal of especially a kind of revolving drum.
The shallow air-floatation pond is widely used as the device that utilizes microbubble to purify waste water.It comprises four concentric drums of scum silica frost surge drum, clear water overflow cylinder, revolving drum and the former water drum separated successively from inside to outside.Wherein the shared tube end plate of scum silica frost surge drum, clear water overflow cylinder and former water drum fixedly installs, and at the bottom of revolving drum do not have tin, and can rotate relative to other three tubes.Be the clear water that comes out of purification separation in the revolving drum, and revolving drum is outward the former water that is purifying.Water body mixes mutually inside and outside the revolving drum, necessary employing dynamic seal at the bottom of revolving drum and the former water drum tube.The dynamic seal mode of existing shallow air-floatation pond revolving drum adopts labyrinth type more, at the bottom of former water drum tube, fixedly install exactly one with the concentric cast wear ring of former water drum, the cross section of wear ring is
Shape; And weld a wire loop in the barrel bottom of revolving drum, the cross section of wire loop is " Π " shape.The cross section of wear ring cooperates with the cross section of wire loop is concavo-convex, realizes sealing, and can relatively rotate.Because the barrel dliameter of revolving drum is bigger, the shape in wear ring cross section and wire loop cross section has particular requirement again, and their processing is difficulty relatively; Wear ring contacts with the wire loop rigidity, deforms easily and stuck; Because wear ring and wire loop are to relatively rotate, and certainly lead to wearing and tearing, sealing effectiveness can decline to a great extent after the overlong time.
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of shallow air-floatation pond of easy to process, stable, the novel dynamic seal of a kind of revolving drum that dynamic seal is effective is provided.
The utility model is achieved in that the shallow air-floatation pond of the novel dynamic seal of a kind of revolving drum, comprise the scum silica frost surge drum of separating successively from inside to outside, clear water overflow cylinder and former water drum, three-cylinder concentric is provided with a shared tube end plate, one wear ring is arranged on the tube end plate between clear water overflow cylinder and the former water drum, the revolving drum at a no end is positioned at the top of wear ring, and with its dynamic seal, be provided with rotary support between the tube top of revolving drum and the tube top of former water drum, revolving drum is fixed on the below of rotary support, rotary support is provided with dreg scraping bucket and motor, the rotary support below is provided with synchronous rotating water inlet device and water outlet device, one former water water inlet pipe is arranged on the central position of former water drum, and by pipeline with the water inlet device communicate, the side is provided with scum pipe under the tube of scum silica frost surge drum, the below of clear water overflow cylinder is provided with the clear water rising pipe, the sidewall that it is characterized in that the cast wear ring is set with preset pieces, preset pieces exceeds wear ring, revolving drum places preset pieces one side and clearance fit, and the outside of seam is equipped with an elastic seal ring between revolving drum and the wear ring.
The shallow air-floatation pond of the novel dynamic seal of described a kind of revolving drum, preset pieces is positioned at the inboard of wear ring, and slight curving in ring.
The shallow air-floatation pond of the novel dynamic seal of described a kind of revolving drum, wear ring and revolving drum are isometrical, are movably arranged on the tube end plate, and its cross section is " L " shape.
The shallow air-floatation pond of the novel dynamic seal of described a kind of revolving drum, preset pieces have 3～8, evenly are provided with along the circumference of wear ring.
After adopting this structure, because the wear ring at the bottom of former water drum tube utilizes self gravitation to realize sealing, and seam is utilized the elastic seal ring sealing between revolving drum and the wear ring, preset pieces defines the position of revolving drum with respect to wear ring, make revolving drum stable, dynamically close effective, and processing and install all very convenient.
Further specify the utility model below in conjunction with Figure of description, and provide embodiment.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged view of A part among Fig. 1 figure.
As shown in the figure, a kind of novel superficial air flotation pool that makes things convenient for scarfing cinder comprises scum silica frost surge drum 3, clear water overflow cylinder 2 and the former water drum 7 separated successively from inside to outside, and three-cylinder concentric is provided with a shared tube end plate 8.Revolving drum 1 relative other three-cylinder concentric at the no end is provided with, and is provided with rotary support 5 between the tube top of its top and former water drum 7, and revolving drum 1 is fixed on the below of rotary support 5.Rotary support 5 is provided with dreg scraping bucket 4 and motor, and motor can drive the edge rotation of rotary support 5 along former water drum 7.Rotary support 5 belows are provided with synchronous rotating water inlet device and water outlet device 6.One former water water inlet pipe 12 is arranged on the central position of former water drum 7, and communicates with the water inlet device by pipeline.The side is provided with scum pipe 13 under the tube of scum silica frost surge drum 3, and the side is provided with clear water rising pipe 11 under the tube of clear water overflow cylinder 2.One cross section is movably arranged on the tube end plate 8 between clear water overflow cylinder 2 and the former water drum 7 for the cast wear ring 10 of " L " shape, and revolving drum 1 is positioned at the top of wear ring 10, can carry out rotation under the drive of rotary support 5.The inboard symmetry of wear ring 10 is set with 4 preset piecess 14, and preset pieces 14 exceeds wear ring 10, and slight curving in ring.The outside of seam is equipped with an elastic seal ring 9 between revolving drum 1 and the wear ring 10, and elastic seal ring 9 is fixed on the wear ring 10 by screw 15.
During work, waste water enters into water device by former water water inlet pipe 12, is entered in the former water drum 7 by the water inlet device again.The scum silica frost on waste water upper strata is scraped into scum silica frost surge drum 3 by dreg scraping bucket 4, discharges by scum pipe 13.The clear water of lower floor enters water outlet device 6, enters the revolving drum 1 into clear water overflow cylinder 2 that overflows by water outlet device 6 again, is discharged by clear water rising pipe 11.Rotary support 5 drives revolving drum 1, water inlet device and water outlet device 6 and rotates synchronously, makes the water body in the former water drum 7 keep static, is beneficial to the scum silica frost come-up.
