Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sludge vibration dewatering screen. Background Art

[0002] Sludge dewatering is an essential part of sludge treatment, and the vibrating dewatering screen is a commonly used equipment in sludge dewatering. The vibrating dewatering screen adopts dual motor self-synchronization technology, universal eccentric block, and adjustable amplitude vibrator. It is mainly composed of screen box, vibrator, support system and motor. Two unrelated vibrators are synchronously reversed, and the centrifugal force generated by the two groups of eccentric masses is superimposed along the vibration direction, and the reverse centrifugal force is offset, thus forming a single excitation vibration along the vibration direction, so that the screen box performs reciprocating linear motion. At present, most of the screen plates of the vibrating dewatering screen still use traditional plate screen plates, which have limited filtration area, resulting in limited sludge dewatering efficiency. Utility Model Content

[0005] Preferably, a liquid collecting layer is provided on the dewatering screen frame directly below the screen, the liquid collecting layer is funnel-shaped as a whole, and a liquid discharge port is provided at the lowest point of the liquid collecting layer.

[0006] Preferably, a liquid outlet pipe passing through the dewatering screen frame is horizontally provided on the overall side wall of the liquid collecting layer.

[0007] Preferably, the length of the screen is 4880 mm and the width is 1830 mm. The thickness of the screen near the feed port is 0.3 mm, and the thickness of the screen near the discharge port is 0.5 mm.

[0008] Preferably, the screen mesh is vertically provided with sieve plates near both sides of the dewatering screen frame, and the height of the sieve plates is 305 mm.

[0009] Preferably, the materials of the screen and the screen plate are both polyurethane.

[0010] Preferably, the plurality of rubber springs are arranged in a rectangular shape as a whole.

[0011] The beneficial effects of the utility model are:

[0012] This vibrating dewatering screen uses a wavy screen, which greatly increases its screening and filtering area by 120% to 150% compared to the plate screen, thereby improving the sludge dewatering efficiency. The rubber spring is more elastic and has a longer life than the steel spring. The dewatering screen frame is provided with a screen at a certain slope. The sludge falls into the screen with a certain slope and moves toward the top of the slope, which can slow down the sludge moving speed and improve the sludge screening efficiency.

[0013] A liquid outlet pipe passing through the dewatering screen frame is horizontally arranged on the overall side wall of the liquid collecting layer. When the liquid discharge port is blocked or the material is fed slowly, the sewage can be discharged from the liquid outlet pipe without affecting the normal sludge dewatering work.
