Description

Dredging system suitable for perforating sludge discharge pipe

Technical Field

The invention relates to a dredging system of a sludge discharge device, in particular to a dredging system of a perforated sludge discharge pipe of an inclined plate sedimentation test device.

Background

A shallow sedimentation tank is arranged between every two parallel inclined plates of the inclined plate sedimentation tank. The treated water and the settled sludge are moved and separated from each other in the shallow layer of sedimentation. The inclined plate sedimentation tank utilizes the principle of 'shallow layer sedimentation', shortens the sedimentation distance of particles, thereby shortening the sedimentation time, increasing the sedimentation area of the sedimentation tank and improving the treatment efficiency. Therefore, the sedimentation tank has small occupied area and is widely applied. The perforated sludge discharge pipe is often used as a sludge discharge system of a sloping plate sedimentation tank due to simple structure and convenient operation. The inclined plate sedimentation test device is not only suitable for scientific research needs, but also suitable for teaching purposes. The perforated holes of the mud discharging pipe are often blocked due to unbalanced hydraulic conditions, so that the applicable range of mud accumulation is limited. When the accumulated mud generated in the test is loose, the mud discharging effect of the perforated mud discharging pipe is good and smooth; if the density of the accumulated mud generated in the test is large or the viscosity is large, the accumulated mud is easy to harden, and the perforations on the perforated mud discharging pipe are easy to block, so that the mud discharging is not smooth, and the water quality range of the test device of the inclined plate sedimentation tank which is suitable for treatment is reduced.

The following describes the use of the present invention in detail.

The perforated sludge discharge pipe is generally used in a tilted plate sedimentation tank, and the perforated sludge discharge pipe is generally suitable for a perforated sludge discharge system of a tilted plate sedimentation test device.

The water treated by the flocculation tank 800 enters a water inlet region 707 of the inclined plate sedimentation tank 700 through a water inlet channel 801, and then rises to a clear water region 709 through an inclined plate 708, and the treated water is collected by a water collecting tank 710 and is discharged out of the system through a water discharge pipe 711. The generated sludge is collected downwards into the sludge collection groove 703 through the inclined plate 712, and when the sludge reaches a certain height, the gate valve of the perforated sludge discharge pipe 701 is opened to discharge the sludge.

When the perforated sludge discharge pipe 701 is blocked, the accumulated sludge in the sludge accumulation groove 703 cannot be discharged in time. The pull rod 602 is pulled, the pull rod 602 drives the connecting rod 601 to move, the connecting rod 601 pulls the outer magnetic block 500 to move on the sliding plate 600, a magnetic field exists between the outer magnetic block 500 and the inner magnetic block 400, and the inner magnetic block 400 can also move along with the outer magnetic block 500 under the action of magnetic force. The inner magnetic block 400 drives the pulley 300 to move in the sliding groove 705, the transverse tube 100 is pushed to move simultaneously, more than two pulleys 300 can be balanced, and the inner magnetic block 400 and the transverse tube 100 are prevented from being overturned. The movement of the transverse pipe 100 can drive the thin vertical pipe 200 to move in the sludge accumulation groove 703, and the thin vertical pipe 200 is moved to the sludge accumulation position retained in the sludge accumulation groove 703. The hose 101 is led to the high pressure water delivery equipment on sedimentation tank 700 top by the clearance between the swash plate 712, opens high pressure water delivery equipment, and the water under high pressure enters into violently managing 100 through hose 101 in, gets into thin standpipe 200 by violently managing 100 again, jets into the long-pending mud through trompil 201 water column, and the long-pending mud that the water column can lubricate the harden increases the mobility of long-pending mud, makes long-pending mud change follow perforation entering perforation mud pipe 701. Simultaneously, at thin standpipe 200 removal in-process, the long-pending mud that can be fine stir hardened makes long-pending mud fluffy, also can make the water column more easily get into the inside of the long-pending mud of hardened in addition, improves the mobility of long-pending mud.
