Embodiment 1

[0032] see Figure 1-4, an integrated sludge concentration tank, including a circular inner pool 1 and a bridge plate 2 located on the upper part of the circular inner pool 1, the circular inner pool 1 is a pool for settling sludge, and the bridge plate 2 is placed on the circular inner pool 1. On the external wall, the bridge plate 2 is the bearing plate of the mud scraping device; the inner barrel 11 distributed with the same axis is fixedly connected in the circular inner pool 1, the top and bottom of the inner barrel 11 are open, and the inner surface wall of the inner barrel 11 passes through The connecting rods 111 evenly distributed in the circumferential direction are fixedly connected with the matching sleeve 112 distributed on the same axis. Distribution, at this time play the role of connection, the evenly distributed connecting rod 111 divides the inner barrel 11 into a plurality of fan-shaped areas, and is located between the inner barrel 11 and the matching sleev...

Embodiment 2

[0034] see Figure 5 The difference with Embodiment 1 is that the floating plate 121 is fixedly set on the side of the rotating shaft 12 and positioned at the second sprocket 4, and the top of the circular inner pool 1 is provided with a water outlet weir 13, and the bottom of the floating plate 121 is submerged in the water outlet weir 13 For the formed drainage water surface, when the S-shaped mud guide plate 31 is distributed horizontally, the floating plate 121 is adjusted to a horizontal state, and the middle part of the floating plate 121 is fixedly connected with the rotating shaft 12. The floating plate 121 is similar to the structure of a seesaw. Under the effect of water buoyancy, ensure that the mud guide plate 31 is horizontally distributed, and the cross section of one end on the floating plate 121, which is located at both sides of the rotating shaft 12, is V-shaped, which increases the stability of the water floating of the floating plate 121; the bottom of the b...

Embodiment 3

[0036] see Figure 6 , based on the difference between Embodiment 1 and Embodiment 2, the connection rod 101 is also included, the two ends of the bottom cross bar of the T-shaped limit frame 81 and the two ends of the floating plate 121 are provided with grooves 9, and the grooves 9 are provided with The two ends of the bolt 91 and the connecting rod 101 are provided with a circular sleeve 1011 matched with the bolt 91, and the mud guide plate 31 is in contact with the sludge. After a period of use, the phenomenon of sticking mud will occur. At this time, the connecting rod 101 is connected to the The T-shaped limit frame 81 is connected with the two grooves 9 on the floating plate 121, and then the return stroke and the push stroke of the cylinder 7 are controlled. Driven by the connecting rod 101, the floating plate 121 will swing rapidly at an angle of 90 degrees, and then The mud deflector 31 is driven to swing rapidly in the water, and the mud deflector 31 without sludge...

Abstract

The invention discloses an integrated sludge thickening tank, which comprises a circular inner tank and a bridge plate located on the upper part of the circular inner tank. In the present invention, an inner barrel distributed concentrically in the circular inner pool is arranged, and there is a circle of S-shaped mud gathering combination connected in rotation in the inner barrel. One structure, the middle part of the inner bucket is connected with a matching sleeve through a connecting rod, and the mud deflector is connected between the matching sleeve and the inner bucket through a fixed shaft. The connecting rods are also uniformly distributed in the circumferential direction and alternately distributed with the mud deflectors, so that the evenly distributed mud deflectors and the connecting plates form an incompletely closed sewage separation layer, and the upwardly opening inner cavity formed on the mud deflectors can accelerate To accumulate sludge, the flipping of the mud guide plate can accelerate the settlement of the accumulated sludge, thereby accelerating the concentration treatment of the sludge, and at the same time has the effect of preventing the sludge in the sewage from floating.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sludge thickening tank. Background technique [0002] Sludge concentration treatment is a treatment method to reduce the water content and sludge volume in sludge. The common concentration treatment methods are divided into centrifugal type and sedimentation type. The sedimentation type is usually carried out in the thickening tank. [0003] At present, the structure of the thickening tank is mainly composed of a sewage tank and a mud scraping device. A mud discharge pipeline is installed at the bottom of the sewage tank. The mud scraping device is located at the bottom of the pool, and its rotation guides the accumulated sludge into the mud discharge pipe, and the supernatant water is discharged through the weir on the top. , this kind of concentration tank adopts the sedimentation type to achieve sludge concentration, and the sludge is in a dispersed stat...
