Abstract

The Sludge Blanket Clarifier relies on the pulsation of water to achieve uniform sludge concentration (Uniform Sludge Concentration) by storing raw water in the Siphon Compartment to the desired level. It causes the siphon condition in the siphon by sucking the compressed air inside out with an air suction device (Ejector) which receives the signal, works or stops. From level measuring devices (Level Switch) and time control devices (Timer) and maintain the siphon condition by preventing the air from entering with a reverse water gate The water in the siphon part flows rapidly through the main pipe, receives the water ripple into the water ripple section and out into the sediment layer in the sedimentation tank through the perforated pipe, causing the sludge layer to ripple and arranged to have a uniform density (Uniform Sludge Concentration). To provide high efficiency flocculation When the water in the siphon is reduced to the lowest level. The level measuring device sends a signal to open the door of the compressed air valve (Solenoid Valve), which is controlled by a timer (timer) to provide compressed air (Air Compressor) that is already in the factory. It generally flows into the inside of the pipe cover, stopping the siphon condition The water in the siphon section will not flow into the main pipe. The pulsation will stop and the water will begin to accumulate in the new siphon section to the desired level. And will produce a siphon and stop the siphon condition Continuously alternate

Claims (4)

1. SLUDGE BLANKET CLARIFIER, which is characterized by a sedimentation component. It is a tank and has a water chipping tower (RIPPLE WATER CHAMBER) in order to allow water to be released into the sediment layer. The water ripple tower is divided into 2 sections with 4 dividing discs, the upper part is the siphon (SIPHON COMPARTMENT) 5, the lower part is the water ripple (RIPPLE WATER COMPARTMENT) 6, with the top 5 siphon open to the atmosphere. (In the event that the top cover is completely closed, ventilation ducts must be performed) The lower water ripple 6 opens to the atmosphere with the vent 7 Raw water flows into the siphon section by raw water pipes as in Figure 5, the inlet water will be reduced speed. With a baffle 14, the water in the siphon section gradually rises to the water level at point 17, the water closes the pipe cover 21. During this time, the SOLENOLD VALVE door 23 and 24 are closed, allowing air to be trapped between the pipe cover and The main pipe receives the water ripple. The water in the siphon can not flow into the pipe to receive water ripple The water level in the tilting section rises more and more as the water level in the galactic section in Figure 6 rises up to the water level at point 18, the water in the cover is placed on the edge of the main pipe. This point is equal to the height of the water level 15 and is equal to the height of the water level 16 pressing the end of the main pipe to ripple 9 at this point according to Figure 7, level measuring device (LEVEL SWITCH) 20 is complete at level L 1 and Send signal to the door, air flap (SOLENOID VALVE) 24 open compressed air (COMPRESSED AIR) 22, which is obtained from the air compressor (AIR COMPRESSOR), which is already in the factory. It flows through the EJECTOR 26, which rapidly sucks the air inside the pipe cover 21 and in the main pipe 9. The intake time can be adjusted with the timer control device (TIMER). 19 At the end of the adjusted time, the SOLENOID VALVE 24 closes the area between the pipe cover and the water intake main pipe, filled with water. This causes the siphon (SIPHON) and the water in the siphon section will rapidly flow into the water pipe 9 to the water ripple area inside the pipe cover 21 becomes a vacuum. Since the gate (SOLENOID VALVE) 23 and 24 are closed and there is a reverse gate (CHECK VALVE) 25, air cannot enter the inside of the pipe around the cover of pipe 21, so the water inside the siphon section will flow continuously to the main pipe. Flutter, which can adjust the amount of water flow in the pipe with the flow control funnel (FLOW CONTROL CONE) 13, which is adjusted up or down by the steering wheel (HAND WHEEL) 11 Pull the shaft (SHAFT) 12 which is connected to Water flow adjustable funnel This makes it possible to adjust the ripple of water towards the sludge to force or gradually to suit the density of the sludge. When the water level in the siphon section drops to the lowest water level at point 17, according to Figure 5, the level 20 measuring device at level L2 sends a signal to open the compressed air valve door (SOLNOID VALVE) 23, which controls the opening and closing time with the device. Set the timer (TIMER) 19 to allow the compressed air (COMPRESSED AIR) to flow into the area of the pipe cover 21 and the area above the main pipe to ripple water 9, causing the siphon condition to disappear. The water in the siphon section stops flowing into the ripple section and begins to rise further until the cover is closed. 21 Water collection cycle. And a new siphon will occur alternately as long as the raw water flows into the siphon. (And stop at that level when no water flows into the siphon To stop the sediment flow as long as desired, set the desired time to open the suction flap gate 24 after the signal from the level 20 measuring device, during which the water in the siphon section will overflow. The overflow drain (OVERFLOW) 8 goes down to the ripple section instead of through the main pipe for the ripple 9. 2. Sedimentation tank according to claim 1, where the position of the water ripple tower can be set both inside and outside the sedimentation tank. 3. The sedimentation tank according to claim 1, where the siphon (SIPHON WATER COMPARTMENT) and the ripple (RIPPLE WATER COMPARTMENT) sections can be installed separately, with the main ripple pipe (RIPPLE WATER COMPARTMENT) welded. Between the two parts 4. The sedimentation tank according to claim 1 is also equipped with an additional pump for pumping water into the siphon section (SIPHON WATER COMPARTMENT) to produce a continuous water ripple in the event that raw water is not pumped into the sedimentation tank.
