Description

Lifting equipment for domestic sludge treatment

technical field

The invention relates to the technical field of sludge transportation, in particular to a lifting device for domestic sludge treatment.

Background technique

Sludge is the solid sedimentation material produced by water and wastewater treatment processes. In sewage treatment, a sludge elevator is often needed to lift the sludge in the sewage. The common sludge elevator is mainly composed of a lifting chain plate and a motor. The motor drives the lifting chain plate to rotate, and the chain plate rotates to bring out the sludge in the sewage. Some sludge hoists will be equipped with a collection bin at the discharge end of the lifting chain plate to collect the sludge falling from the lifting chain plate. When the sludge falls from the lifting chain plate, some sludge will still adhere to the lifting chain plate, and this part of the sludge will continue to return to the sewage as the lifting chain plate rotates, which makes the sludge lifting efficiency of the sludge elevator decrease.

The friction rollers 103 are provided with several and are connected between the two diagonally mounted strips 101 at equal intervals. A pair of conical friction wheels 104 are symmetrically connected to the left and right sides of 3, and all the friction rollers 103 are connected by a conveyor belt 105. The cross section of the conveyor belt 105 is a "︺"-shaped structure. There is a transmission wheel one 107, and all transmission wheels one 107 on the same side are connected by a transmission belt one 108. The underside of the obliquely mounted strip 101 is connected with a right-angled triangular support frame 109, and is vertically connected with several support legs 110 at the bottom of the support frame 109. The middle part of the support frame 109 is vertically welded with a fixed plate 111. The motor 112 is provided with a pair of fixed plates 111 installed on both sides. The output end is connected with transmission wheel 2 113, and the left and right ends of the friction roller 103 in the middle are connected with transmission wheel 3 114, and the transmission wheel 113 and transmission wheel 3 114 on the same side are connected by a transmission belt 2 115. By using the motors 112 on both sides, the transmission belt 115 and the transmission belt 115 on the same side can drive all the friction rollers 103 to rotate, and then drive the conveyor belt 105 and the conveyor plate 106 on it to move. When the conveyor plate 106 moves to the highest point, the sludge on the conveyor belt 105 can fall down under its own gravity. Of course, during the process of dumping the sludge, some sludge with strong adhesion will remain on the conveyor belt 105 and the conveyor plate 106 .

In this embodiment, the cleaning mechanism 20 includes a vertical mounting frame 201, a horizontal mounting frame 202, a suspension mounting bar 203, a cleaning plate 206, and a clamping plate 215.

When the conveying plate 106 moves to the highest point and continues to approach the cleaning plate 206, first use the water spray hole 206b on the cleaning plate 206 to spray the high-pressure water flow to the lower connection between the conveying plate 106 and the conveyor belt 105, and then clean the sludge that may exist in this part by high-pressure flushing. When the conveying plate 106 is attached to the cleaning plate 206 and moves downward around the highest friction roller 103, it will press the cleaning plate 206 and move down along the guide columns 204 on both sides, and the hinge bar 211 that moves down synchronously with the cleaning plate 206 will bring the hinge frame 1 212 and the clamping plate 215 on both sides inwardly and turn down 90 degrees, so that the clamping plates 215 on both sides appear on the top of the conveying plate 106 in parallel, and then use the clamping plate The water spray hole 2 215b on the 215 sprays the high-pressure water flow to the connection between the conveying plate 106 and the upper side of the conveying belt 105 . And when conveying plate 106 slides out between cleaning plate 206 and a pair of clamping plates 215 in the process of moving down, cleaning plate 206 gets back to initial height upwards under the effect of back-moving spring 209 on both sides, and the hinged bar 211 that moves up synchronously with cleaning plate 206 can be with hinge frame one 212 and clamping plate 215 on both sides outwards and upturn 90 degrees, and get back to initial state.

In this embodiment, a vibrating motor 207 is centrally installed on the lower side of the cleaning plate 206 . The cleaning plate 206 can be vibrated by activating the vibration motor 207 , and then the conveying plate 106 in contact with the cleaning plate 206 can vibrate synchronously, thereby helping to clean up the sludge attached to the conveying plate 106 .

When the conveyor plate 106 moves to the highest point, the sludge on the conveyor belt 105 can fall down under its own gravity. Of course, during the process of dumping the sludge, some sludge with strong adhesion will remain on the conveyor belt 105 and the conveyor plate 106 .

(2) When cleaning the sludge, when the conveying plate 106 moves to the highest point and continues to approach the cleaning plate 206, first use the water spray hole 206b on the cleaning plate 206 to spray the high-pressure water flow to the lower connection between the conveying plate 106 and the conveyor belt 105, and then clean the sludge that may exist in this part by high-pressure flushing. When the conveying plate 106 is attached to the cleaning plate 206 and moves downward around the highest friction roller 103, it will press the cleaning plate 206 and move down along the guide columns 204 on both sides, and the hinge bar 211 that moves down synchronously with the cleaning plate 206 will bring the hinge frame 1 212 and the clamping plate 215 on both sides inwardly and turn down 90 degrees, so that the clamping plates 215 on both sides appear on the top of the conveying plate 106 in parallel, and then use the clamping plate The water spray hole 2 215b on the 215 sprays the high-pressure water flow to the connection between the conveying plate 106 and the upper side of the conveying belt 105 .
