The air source device is used for supplying air flow to the push flow air blowing assembly 10, the guide flow air blowing assembly 20 and the air flow injection assembly 30, and can be freely switched between an opening state and a closing state. Alternatively, the gas supply means may be, but is not limited to, a gas tank equipped with a solenoid valve that is electrically connected well to the PLC means.
The plug flow air-blowing component 10, the drainage air-blowing component 20 and the air flow injection component 30 are respectively installed at preset positions of the tank body 110 and the screen 100, and air flow is injected into sewage from different directions and angles, so that impurities are pushed to be far away from the screen 100 to flow away, and the anti-blocking purpose is achieved.
The air source device is electrically connected with the controller and can be started or stopped to supply air; the plug flow air blowing assembly 10 is electrically connected with the air source device and is used for being installed on the upstream pool wall at the water outlet of the purification pool; the drainage air blowing assembly 20 is electrically connected with the air source device and is used for being installed on the downstream tank wall at the water outlet of the purification tank; the first guide plate is used for being arranged on the pool wall and positioned between the flow pushing air-blowing assembly 10 and the screen 100, and the second guide plate is used for being arranged on the pool wall and positioned between the flow guiding air-blowing assembly 20 and the screen 100; the guiding mechanism 60 is configured to be disposed above the surface of the screen 100, and the guiding mechanism 60 includes a mounting seat 61, a guiding claw 62, and a moving component 63 disposed on the mounting seat 61 and configured to drive the guiding claw 62 to move; wherein the guide claw 62 moves in the same direction as the sewage flows.
The anti-blocking air flow guiding device is used for being installed in the biological purification tank and is specifically installed in a matching mode with the screen 100 at the water outlet, so that impurities in sewage close to the screen 100 are blown and guided away through air flow, and the impurities are prevented from being accumulated on the screen 100 to cause blockage. Specifically, the air source device is electrically connected with the controller well and can be controlled by the controller to start or stop air supply; further, the flow pushing and blowing assembly 10, the flow guiding and blowing assembly 20, and the air jet assembly 30 are respectively installed at preset positions of the tank body 110 and are respectively communicated with the air source device. Therefore, when the plug flow air blowing component 10 works, air can be blown towards the downstream direction of the screen 100, so that the plug flow effect is achieved on various impurities floating in sewage, and the impurities are prevented from being accumulated on the screen 100 under the action of water flow; the drainage air blowing assembly 20 can also blow air towards the downstream direction of the screen 100, so that various impurities floating in the sewage are further drained, and the impurities cannot be accumulated on the screen 100; meanwhile, the air jet assembly 30 installed on the surface of the screen 100 also jets high-speed air flow in a direction away from the screen 100 at the same time, so that the impurities in the sewage can be further rapidly pushed away by the air flow pushing force. The first guide plate 40 and the second guide plate 50 are provided to prevent impurities from flowing into dead spaces at the junction of the tank wall and the screen 100 to be accumulated, thereby blocking the edge portion of the screen 100. Meanwhile, the moving component 63 outputs power to drive the guide claws 62 to move, and the moving direction of the guide claws 62 is ensured to be the same as the sewage flow direction. In this way, the various floating impurities are scraped by the guide claws 62 and guided to move in the downstream direction of the screen 100 before flowing close to the screen 100 with the sewage, so as to prevent the impurities from contacting the surface of the screen 100. So far, above-mentioned each device cooperates with each other, can effectively avoid floating impurity such as injection branch, plastic bag, hair in the sewage to pile up on screen cloth 100, cause the mesh to block up, influence screen cloth 100 ability of crossing water, and then influence biological purification tank's sewage treatment ability.
It should be noted that the tank body 110 of the present embodiment is a circular or rectangular structure, and the water inlet and the water outlet are respectively disposed at two opposite positions of the tank body 110. The middle part of the tank body 110 is provided with a plurality of retaining walls which play a role in flow equalization and flow distribution. The area close to the water outlet forms an MBBR area, and biological purification filler is added into the MBBR area and is used for carrying out biological purification treatment on the sewage. In order to improve the treatment efficiency, the sewage in the area flows circularly through the flow pusher, so that the biological filler is driven to flow to fully contact and react with the sewage. Therefore, impurities such as branches, plastic bags, leaves, hair and the like floating in the sewage can be gathered along the direction of the water flow flowing to the screen 100 (namely the water outlet), and are easy to be accumulated on the screen 100 to cause blockage. In view of this, the anti-blocking measures and principles adopted by the scheme are to block the flow of the impurities in the sewage in an air flow blowing mode, and further change the flow direction of the impurities through air flow guiding force, so that the impurities bypass the screen 100 to eliminate the hidden danger of blocking.
Referring to fig. 1, in an embodiment, the flow pushing and blowing assembly 10 includes at least two flow pushing and blowing valves 11, the at least two flow pushing and blowing valves 11 are disposed on the tank wall of the purification tank at intervals along the tank depth direction, and the blowing paths are parallel to each other. Thus, at least two air flow beams ejected by the two longitudinally arranged flow pushing air blowing valves 11 can form an air wall, so that impurities flowing through the air wall are changed in flow direction, namely, the impurities flow away in a downstream direction far away from the screen 100, and the problem of blockage on the surface of the impurity accumulation screen 100 is solved. It should be noted that, under the condition of space and cost allowance, the plug air-blowing valve 11 can be arranged as many as possible, so as to improve the plug effect.
In another embodiment, the plug flow blowing assembly 10 includes at least two plug flow blowing valves 11, the at least two plug flow blowing valves 11 are disposed on the tank wall of the purification tank at intervals along the tank depth direction, and blowing paths of two adjacent plug flow blowing valves 11 form an included angle and form a first confluence point. The difference with the above scheme lies in that the air beams of different plug flow air-blowing valves 11 form a first confluence point, and an air flow disturbance effect is generated at the first confluence point due to the intersection of different air beams, so that the established flow direction of impurities can be better prevented, the flow in the downstream direction far away from the screen 100 is changed, and the purposes of preventing blockage of the screen 100 and ensuring the water passing capacity of the screen 100 are achieved.
With reference to fig. 1, in a further embodiment, the anti-blocking airflow guiding device further includes a first guide rail 70 disposed on the wall of the purifying tank, and at least two of the plug-flow air-blowing valves 11 are disposed on the first guide rail 70 by moving a first power cart. Therefore, the plug flow air-blowing valve 11 can be flexibly moved according to different water surface heights caused by different water flows in the tank body 110, so that the plug flow air-blowing valve 11 can be reliably immersed below the water surface all the time to ensure normal operation.
In addition, the drainage air-blowing assembly 20 comprises at least two drainage air-blowing valves 21, wherein the at least two drainage air-blowing valves 21 are arranged on the pool wall of the purification pool at intervals along the pool depth direction, and air-blowing paths are parallel to each other.
