Description

A vacuum backwashing structure for cleaning a water collection tank in a pump station and a control method thereof

Technical Field

The invention relates to the technical field of water treatment, in particular to a vacuum backwashing structure for cleaning a water collection tank of a pump station and a control method thereof.

Background Art

The vacuum backwashing structure of the sump of a cleaning pump station usually consists of a vacuum generator, a backwashing pipe system, an automatic control system and a valve system.

The patent with patent announcement number CN213270311U relates to a vacuum backwashing structure for cleaning a water collection tank of a pump station. A negative pressure water diversion chamber is added to the water outlet side of the water collection tank, and the negative pressure water diversion chamber is connected to the bottom of the water collection tank by a through hole, and an integrated vacuum water diversion equipment is installed on the top of the negative pressure water diversion chamber. By utilizing the liquid level difference, water flows from the negative pressure water diversion chamber through the bottom through hole to flush the water collection tank of the pump station without dead ends. The powerful flushing flow flushes the bottom foot of the grille in the opposite direction, effectively alleviating the chain breakage and chain falling phenomenon caused by foreign matter blocking the grille during operation, thereby increasing the service life of the equipment, avoiding manual dredging and mechanical sewage suction, and reducing costs.

In the above patent, by utilizing the liquid level difference, water is discharged from the negative pressure water diversion chamber through the bottom through hole to flush the pump station collection tank without dead angles. The powerful flushing flow reversely flushes the base of the grille installation, thereby increasing the service life of the equipment, avoiding manual dredging and mechanical sewage suction, and reducing costs. However, it is difficult to adjust the flushing angle of the cleaning medium when the cleaning medium flushes the pump station collection tank. It is difficult to adjust the flushing angle, which will result in the cleaning medium failing to fully cover or flush all parts of the filter screen, reducing the cleaning effect, so that some areas are still affected by dirt and cannot be completely cleaned.

A method for using a vacuum backwashing structure for cleaning a water collection tank in a pump station comprises the following steps:

Step 1: Before vacuum backwashing the water collection pool of the pump station, turn the butterfly valves inside the water outlet and the water inlet to seal the water outlet and the water inlet. After the water outlet and the water inlet are sealed, start the vacuum pump to evacuate the sewage pool so that the inside of the sewage pool remains in a vacuum state;

Step 2: Start the electric push rod to move downward to drive the cleaning rack to move downward, the cleaning rack moves downward to drive the rotating rod to move, the rotating rod moves to drive the backwashing device to move, and the backwashing device moves to flush the filter plate;

Step 3: When the backwashing device moves to the bottom of the sewage pool, it contacts and squeezes the fixed rod. The backwashing device rotates clockwise under the reaction force of squeezing the fixed rod to change the angle of flushing the filter plate;

Step 4: Wait for the electric push rod to reset and move upward to drive the backwashing device to move upward and reset. The backwashing device moves upward and resets. Under the action of its own gravity, it rotates counterclockwise to drive the fixed ring to rotate and contact the rubber block. At this time, the rotating block cannot rotate and squeezes the rubber block, and the rubber block is squeezed by the rotating block to produce deformation;

Step 5: The rubber block can only be deformed slowly due to the non-Newtonian fluid inside it. The slow deformation of the rubber block causes the fixing ring to rotate slowly counterclockwise. The slow counterclockwise rotation of the fixing ring drives the rotating rod and the backwashing device to rotate slowly counterclockwise to flush the filter plate at multiple angles.

Step 6: When the electric push rod is in operation, it moves downward to contact the scraper and drives the scraper to move downward to scrape the filter plate. After the backwashing equipment is finished, the seal of the drain hole is released and the cleaned sewage mixture is discharged from the sewage pool through the drain hole.

The present invention provides a vacuum backwashing structure for cleaning a water collection tank in a pump station and a control method thereof. It has the following beneficial effects:

(1) The invention, through the slow deformation of the rubber block, causes the rotating block and the fixed ring to slowly rotate counterclockwise. The slow counterclockwise rotation of the fixed ring drives the rotating rod and the backwashing device to slowly rotate counterclockwise to flush the filter plate at multiple angles. The slow counterclockwise rotation can ensure that the water flow covers the surface of the filter plate, including the edges and corners, ensuring that all areas are fully flushed, thereby improving the cleaning effect and making the cleaning effect more thorough. At the same time, the electric push rod moves downward to contact the scraper and drives the scraper to move downward to scrape the filter plate. The downward pressing action of the scraper can scrape dirt or grime from the surface of the filter plate, making the cleaning process of the backwashing device more thorough.

(2) In the present invention, the filter plate is reset by the elastic force of the reset spring, and the filter plate reciprocates accordingly to enhance the flushing effect of the backwashing device on the filter plate. The reciprocating motion of the filter plate can increase the coverage of the flushing effect, so that the cleaning medium can be more evenly distributed on the surface of the filter plate, which helps to improve the flushing efficiency of the backwashing device and accelerate the process of removing dirt. At the same time, the filter plate is reset by the elastic force of the reset spring and moves in the direction close to the telescopic tube. The filter plate moves and hits the protrusion to generate vibration. The vibration can increase the impact force between the filter plate and the flushing medium, which helps to effectively clean the dirt from the filter plate and further improve the flushing effect of the backwashing device.

(3) In the present invention, a quantitative cleaning agent enters the sealing frame and is sprayed onto the surface of the filter plate through a spray pipe. The cleaning agent can dissolve or wash away dirt or other impurities attached to the filter plate, thereby ensuring the cleaning efficiency of the backwashing equipment. By controlling the amount of cleaning agent used, excessive use or waste can be avoided. At the same time, the spray rod moves upward to contact the spray pipe and squeezes the spray pipe to deform. The deformation of the spray pipe allows the cleaning agent to be sprayed onto the surface of the filter plate more evenly. The deformed spray pipe may better adapt to the contour and curve of the filter plate surface, thereby improving the coverage rate of the cleaning agent and ensuring that each area is properly covered by the cleaning agent, thereby preventing dead corners or loopholes.
