Embodiment 1

[0041] Such as Figure 1-8 Shown, the present invention a kind of sludge removal method in the settling tank in sewage treatment,

[0042] Step 1. Set up a walking frame device above the sedimentation tank 6, and a cover lifting device is arranged on the walking frame device. Four lifting screws 7 on the cover lifting device are connected with a sealed U-shaped cover 1, and the cover lifting device Control the lifting of the sealed U-shaped button cover 1 in the sedimentation tank 6;

[0043] Step 2. A bidirectional lead screw 8 is horizontally suspended inside the sealed U-shaped buckle cover 1. The two ends of the bidirectional lead screw 8 are provided with corresponding opposite threads, and the two ends of the bidirectional lead screw 8 are provided with spline grooves. The two ends of the two-way lead screw 8 are threadedly connected with a scraper 2 respectively, and the end face of the scraper 2 is slidably and sealingly connected with the inner wall of the sealed U-s...

Embodiment 2

[0059] Such as Figure 1-8 As shown, the present invention is a method for removing sludge in a sedimentation tank in sewage treatment. On the basis of Embodiment 1, this embodiment adds the function of removing scum, and a scum retainer is hung on one side of the walking frame device plate 23, and the scum baffle plate 23 is attached to the outer wall of one side of the sealed U-shaped button cover 1. The scum baffle 23 is inserted in the sewage to isolate the scum on one side, so that when the sealed U-shaped button cover 1 descends into the sewage, the scum collected on one side of the scum baffle 23 will be covered on the sealed U-shaped button. In the cover 1, when the sludge is subsequently sucked, the scum is sucked and removed together with the sludge, and the walking frame device continuously drives the scum baffle 23 to move in one direction of the sedimentation tank 6, so that the scum will be continuously sealed. The type button cover 1 is covered and subsequently...

Embodiment 3

[0061] Such as Figure 1-8 As shown, the present invention is a method for removing sludge in a sedimentation tank in sewage treatment. On the basis of the above-mentioned embodiments, the walking frame device includes a walking motor 24, a pulley 25 and a support shaft 26. A guide rail 27 is laid on the top, at least two support shafts 26 are erected on the sedimentation tank 6, pulleys 25 are provided at both ends of the support shaft 26, and the pulleys 25 are slidably arranged on the guide rail 27, and the support shafts 26 are connected and fixed by connecting rods. The traveling motor 24 is connected to at least one pulley 25 through a transmission chain, and the traveling frame device is driven by the traveling motor 24 to move on the guide rail 27 . Walking frame device is exactly a support walking frame, controls walking frame to move on setting guide rail 27 by controlling traveling motor 24.

Abstract

The invention discloses a method for removing sludge in a sedimentation tank in sewage treatment. By controlling the walking frame device, the sealed U-shaped button cover is moved to the position of the sedimentation tank where sludge needs to be removed, and the button cover lifting device is controlled to make the sealing The U-shaped buckle cover falls vertically, so that the sealed U-shaped buckle cover is buckled at the bottom of the sedimentation tank, and the mud-scraping drive motor drives the telescopic shaft to rotate. The rotation of the telescopic shaft first drives the extrusion wheel to move downward, and the extrusion wheel moves downward. Move and squeeze the sealing guide plate, so that the two U-shaped sealing buckle covers on the sealing U-shaped buckle cover are expanded outwards, so that the lower water hole on the sealing U-shaped buckle cover and the upper water hole on the U-shaped sealing button cover Dislocation occurs, the lower water hole is sealed, the telescopic shaft continues to rotate, the bottom end of the telescopic shaft is tightened with the bevel gear of the motor, and then the two-way screw rotates to drive the scraper and the agitating brush to work, and the suction pump is started to suck the mud. Setting, when the two scrapers are close together, the removal of the deposited sludge in the sealed U-shaped button cover is completed.

Description

technical field [0001] The invention relates to sewage treatment equipment and the technical field, in particular to a method for removing sludge in a sedimentation tank in sewage treatment. Background technique [0002] In sewage treatment, sedimentation is one of the most basic methods in sewage treatment. It is a process that uses the settleability of suspended particles in water to sink under the action of gravity field to achieve solid-liquid separation. This process It is simple and easy to implement, widely used, and the treatment cost is low, and it can be a certain process in the whole sewage treatment process. [0003] In the above-mentioned sewage treatment process, the sedimentation sludge treatment is a problem that must be considered. With the continuous innovation of sewage sedimentation treatment technology, there are also various sedimentation tanks. Regardless of the structure of the sedimentation tank, after the separation of water and sediment is achieved...
