Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge filtration and separation mechanism. Background Technology

[0002] Wastewater contains a large amount of colloidal sludge composed of organic debris, bacterial cells, inorganic particles, and colloids. Currently, the main method for separating sludge from wastewater is sedimentation, which causes the sludge to aggregate and settle. The supernatant and the sludge are then discharged separately for separation. Sludge and water cannot be directly separated, and the slow settling speed of the sludge results in low sludge separation efficiency. Furthermore, the sludge is not concentrated and has a high water content. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a sludge filtration and separation mechanism.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

The sludge-water separation cylinder has an upward-facing sludge inlet on its bottom side wall. The bottom end of the sludge-water separation hopper is connected to the sludge inlet, thus connecting the sludge-water separation hopper and the sludge-water separation cylinder. The sludge-water separation cylinder and the stainless steel sludge discharge cylinder are coaxial and connected. The upper end of the auger is inserted into the hollow shaft of the geared motor. The geared motor drives the auger to rotate within the sludge-water separation cylinder and the stainless steel sludge discharge cylinder, lifting the sludge upwards.

One end of each connecting rod passes through a circular hole in the lower end plate and is secured with a hexagonal nut, while the other end of the connecting rod passes through a circular hole in the upper end plate and is secured with a hexagonal nut. The sludge-water separation cylinder and the stainless steel sludge discharge cylinder are sandwiched between the four connecting rods. The uprights are screwed to the base plate, and the sludge-water separation hopper is installed on top of the uprights.

[0007] The lower end plate has a lower bearing mounting groove at the top center, in which a lower ball bearing is installed. The upper end plate has an upper bearing mounting groove at the bottom center, in which an upper ball bearing is installed. The two ends of the auger's shaft are respectively fitted into the inner rings of the lower ball bearing and the upper ball bearing.

[0008] The mud-water separation hopper includes an annular stainless steel support ring, a funnel-shaped stainless steel mesh hopper, and a funnel-shaped filter cloth hopper. The stainless steel support ring is fixed to the top of the stainless steel mesh hopper. The stainless steel support ring has four socket holes arranged in a circular array. The top of the upright is inserted into the socket holes from bottom to top. The filter cloth hopper is installed inside the stainless steel mesh hopper.

The stainless steel mesh cylinder is sandwiched between four connecting rods. The upper end of the stainless steel mesh cylinder is welded to the stainless steel sludge discharge cylinder. The filter cloth cylinder is installed inside the stainless steel mesh cylinder.

[0010] The stainless steel sludge discharge cylinder has a discharge port on the upper side wall for discharging sludge, and a downwardly inclined discharge trough is welded on the stainless steel sludge discharge cylinder to connect the discharge port.

[0011] The auger includes a rotating shaft, spiral auger blades, and multiple pairs of dispersing teeth arranged in a circular array. The auger blades and dispersing teeth are welded to the rotating shaft, and the dispersing teeth are located near the upper end of the rotating shaft.

[0012] The pitch of the auger blades gradually decreases from bottom to top.

[0013] The mud-water separation hopper is in a vertical position, and the angle between the central axis of the mud-water separation cylinder and the central axis of the mud-water separation hopper is 30~60°.

[0014] Preferably, the sludge filtration and separation mechanism further includes a rectangular box-shaped water receiving trough, which is located below the sludge-water separation cylinder and the sludge-water separation hopper.

[0015] The beneficial effects of this utility model are as follows: when sewage is discharged into the sludge-water separation bucket, the sludge in the sewage is trapped in the sludge-water separation bucket and the sludge separation cylinder, and the water is discharged through the sludge separation bucket and the sludge separation cylinder, which can directly separate sludge and water and improve sludge separation efficiency by using filtration separation; the geared motor drives the auger to rotate and lift and squeeze the sludge entering the sludge separation cylinder, which can not only discharge the sludge, but also further reduce the water content of the sludge.

[0031] The bottom side wall of the mud-water separation cylinder 3 has an upward-facing mud inlet 31, and the bottom end of the mud-water separation bucket 2 is connected to the mud inlet 31 so that the mud-water separation bucket 2 and the mud-water separation cylinder 3 are connected.

[0032] The mud-water separation hopper 2 is in a vertical position, and the angle between the central axis of the mud-water separation cylinder 3 and the central axis of the mud-water separation hopper 2 is 30° to 60°. In this embodiment, the angle between the central axis of the mud-water separation cylinder 3 and the central axis of the mud-water separation hopper 2 is 60°.
