[0002] Inclined plate sedimentation tank is a common and efficient water treatment equipment, mainly used for removing suspended solids and sludge in water, and its working principle is based on the principle of "shallow sedimentation", by setting a group of parallel inclined plates in the water (or wastewater) to be treated, to shorten the particle settling distance, thereby shortening the sedimentation time, and increasing the sedimentation area of sedimentation tank, improve processing efficiency, specifically, when water flow enters inclined plate sedimentation tank, a slow-flowing area is formed in the sedimentation tank, in this area, solid particles suspended in water begin to settle to the bottom under the action of gravity, forming a sludge layer, and the supernatant layer flows out through the water outlet on the upper part of the sludge layer, while the sludge at the bottom is discharged through the sludge discharge system.

[0003] In the current application of small independent inclined plate sedimentation tank process, the angle of inclined plate is often a fixed value, which makes the equipment often unable to optimize the sedimentation effect by adjusting the angle of inclined plate, such as reducing turbulence and improving the settling velocity of particles, and the change of water quality will affect the settling velocity and sedimentation effect of particles.

[0021] The above, by designing adjusting assembly 4, when the angle of inclined plate 3 is adjusted, two groups of drive assemblies 5 can drive two crossbeam plates 42 to slide up and down between the two steel plates 41, at this time, the rotation point of drive arm one 43 and crossbeam plate 42 moves up and down, when the bottom end of drive arm one 43 rotates, the upper end of drive arm one 43 drives the bottom end of drive arm two 44 to rotate, the pivot shared by drive arm two 44 and inclined plate 3 rotates, and then the angle of inclined plate 3 is adjusted, so that inclined plate 3 can be adjusted according to different conditions, and inclined plate 3 can also be turned to vertical for easy dirt falling and flushing when cleaning, which is very convenient. Note that the connecting shaft between inclined plate 3 and drive arm two 44 penetrates sedimentation tank body 1 and is provided with a sealing ring to avoid water leakage. This is the existing design, which will not be described here.

[0022] The driving assembly 5 comprises two-way screws 51 rotatably connected between the two steel plates 41, the two ends of the two-way screws 51 are oppositely threaded and are threadedly connected with driving blocks 52, the top of the driving block 52 is connected with a driving plate 53 between the cross beam plate 42, the upper and lower ends of the driving plate 53 are rotatably connected with the driving block 52 and the cross beam plate 42, a hand wheel 54 for driving the two-way screws 51 to rotate is mounted on the side wall of one of the steel plates 41, and a synchronous assembly 6 is butted between the two two-way screws 51, the synchronous assembly 6 comprises two synchronous heads 61, the two synchronous heads 61 are respectively mounted on one side of the two steel plates 41 in the two sets of adjusting assemblies 4 and are butted with the rotating shafts of the two-way screws 51, and a synchronous belt 62 is connected between the two synchronous heads 61.
