Description

Technical Field

[0001] The present invention relates to the technical field of magnetic separation wastewater treatment, and more specifically, to a magnetic separation wastewater equipment and treatment system. Background Art

[0002] Magnetic separation wastewater equipment is a device that uses magnetic force to separate magnetic pollutants in wastewater from water. Common magnetic separation wastewater equipment and magnetic separation methods are as follows: high gradient magnetic separator, disk magnetic separator and superconducting magnetic separator, etc. Common magnetic separation methods: direct magnetic separation, indirect magnetic separation and magnetic filtration, etc.

[0003] The existing magnetic floc separation methods have poor adaptability to magnetic flocs with different properties and characteristics. Different magnetic flocs differ in magnetic strength, particle size, floc structure, etc., and traditional methods are difficult to flexibly adjust separation methods and parameters according to these differences, resulting in the inability to achieve efficient separation of various magnetic flocs. In view of this, we propose a magnetic separation wastewater equipment and treatment system. Summary of the invention

[0004] The object of the present invention is to provide a magnetic separation wastewater equipment and treatment system to solve the technical problem that the existing magnetic floc separation method has poor adaptability to magnetic flocs with different properties and characteristics.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a magnetic separation wastewater equipment and treatment system, comprising a magnetic separation wastewater equipment with a magnetic powder recovery chamber, two support frames arranged inside the magnetic powder recovery chamber, a vibration separation mechanism arranged between the two support frames, a pick-and-place unit arranged between the two support frames, and a suction unit of a transmission component arranged on the vibration separation mechanism, wherein undulating grooves are respectively opened on opposite sides of the two support frames, and the undulating grooves are in an annular wave shape;

[0006] The vibration mechanism includes a transmission rod, which is rotatably connected between two support frames, and the suction unit is arranged inside the transmission rod. The two ends of the transmission rod are respectively hinged with a plurality of telescopic rods in a ring array, and the two groups of telescopic rods are arranged in a staggered manner. Each output shaft of the telescopic rod is hinged with a vibration plate, and the plurality of vibration plates are arranged in a ring wave shape; the suction unit includes a plurality of secondary holes, a movable plug and a tension spring;

[0007] A number of vibration plates rotate and move through the undulating grooves, so that the vibration plates rotate in a circular wave-like manner, causing two adjacent vibration plates to move alternately and collide with the magnetic flocs;

[0008] When several vibration plates rotate slowly, the movable plug is at the lowest position and moves out of the secondary hole by its own gravity, forming a flow space to absorb the flocs floating inside the separation chamber;

[0009] When a plurality of vibration plates rotate rapidly, the plurality of vibration plates move rapidly and staggeredly, exerting an impact force on the magnetic flocs, causing the magnetic powder to separate from the flocs. The present invention sets a vibration separation mechanism, and the vibration plates can make circular wave-like motions, causing the vibration plates to make up-and-down motions. When the vibration plates rotate at high speeds, the magnetic flocs can be efficiently impact-separated. When the vibration plates rotate at slow speeds, the magnetic powder and flocs being separated can be sucked out separately through the pick-and-place unit and the suction unit. Compared with other separation methods, this method is not limited by the gravity sedimentation speed, can achieve the separation of magnetic powder and flocs in a short time, and can better adapt to the separation requirements of different magnetic flocs.

[0010] Preferably, the vibration separation mechanism further comprises a plurality of bar magnets, and the plurality of bar magnets are movably sleeved inside the vibration plate.

[0011] Preferably, both ends of each vibration plate are fixedly connected with guide rods, and the guide rods are movably connected inside the undulating groove.

[0012] Preferably, the two ends of the transmission rod are respectively fixedly connected with a first gear, and the two support frames are movably connected with a gear ring on the side away from the vibration plate, and each of the gear rings is meshed with a plurality of second gears in a circular array, and the second gears are meshed with the first gears for transmission, and a plurality of motors are fixedly connected to one side of the right support frame, and the motor drive shaft is transmission-connected with the second gear.

[0013] Preferably, the pick-and-place unit comprises through holes, and the through holes are opened on the surfaces of two support frames.

[0014] Preferably, a scraper is fixedly connected inside the through hole, and the scraper passes through the left support frame, and the scraper is in active contact with the inner wall of the vibration plate, a gas connection port is opened at one end of the scraper, and the right support frame is fixedly connected with a connecting tube.

[0015] Preferably, several of the secondary holes are opened in a linear array on the surface of the transmission rod, and a movable plug is movably sleeved inside each of the secondary holes. One end of each movable plug close to the inside of the transmission rod is fixedly connected to a tension spring, and the other end of the tension spring is fixedly connected to the inner wall of the transmission rod.

[0016] A method for treating magnetic separation wastewater equipment comprises the following steps:

[0017] S1. Preparation before use: the connecting tube is connected to the pipeline for conveying magnetic flocs to convey the magnetic flocs for separation; the gas connection port is connected to an external air pump to convey magnetic powder; the input end of the transmission rod is connected to an external air pump to extract the flocs;

[0018] S2, magnetic floc collision separation;

[0019] S2.1. Magnetic floc collision: The motor is driven to work by an external circuit mechanism, and the motor drives the second gear to rotate, and through the gear meshing transmission, the first gear and the gear ring rotate, driving the transmission rod to rotate at high speed, and the transmission rod rotates through the telescopic rod to drive the vibration plate to rotate, and the vibration plate rotates in the undulating groove through the guide rod, causing the vibration plate to rotate in a circular wave-like manner, colliding with the magnetic floc at high speed, separating the magnetic powder from the floc, and the floc is scattered in several vibration plates;

[0020] S2.2. Slow rotation of the vibration plate: The vibration plate is driven by a motor to rotate slowly. When the bar magnet is at a high point, the bar magnet moves downward, causing the bar magnet to attract the magnetic powder, and then the magnetic powder on the inner wall of several vibration plates is scraped off by a scraper. When the movable plug rotates to the lowest point on the transmission rod, the movable plug moves under the action of its own gravity to form a flow space, and the air pump is operated through an external control system, so that the flocs enter the transmission rod from the flow space, resulting in a floc removal effect.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention sets a vibration separation mechanism, and the vibration plate can make a circular wave motion, causing the vibration plate to make an ups and downs motion. When the vibration plate rotates at a high speed, the magnetic flocs can be efficiently impact-separated. When it rotates slowly, the magnetic powder and flocs in separation can be sucked out separately through the pick-and-place unit and the suction unit. Compared with other separation methods, this method is not limited by the gravity sedimentation speed, can achieve the separation of magnetic powder and flocs in a short time, and better adapt to the separation requirements of different magnetic flocs.

[0023] 2. The present invention sets a movable plug. When the movable plug rotates to the lowest position, the movable plug moves downward due to its own gravity to form a flow space for absorbing the separated flocs. When the movable plug rotates upward, the flow space is closed to prevent magnetic powder from floating above the separation chamber and being sucked into the transmission rod, which affects the collection effect of the magnetic powder and flocs.
