[0001] The utility model relates to a high-pressure water spraying device for a concentration tank with an anti-splashing function, belonging to the technical field of mineral processing equipment. Background Art

[0002] During operation in the concentrator's concentrator tank, the high-pressure nozzles atop the high-efficiency concentrator continuously operate to eliminate foam within the tank. When the rotating rakes rotate to the spraying position below the nozzles, large amounts of high-pressure water are sprayed onto the rakes and rotating cages, splashing everywhere. This can easily cause short circuits in the cage electrical circuits and corrosion in the rotating cage brackets, leading to equipment damage, production stoppages, and electric shocks. Therefore, it is essential to develop a high-pressure water spraying device for the concentrator tank with splash-proof functionality. Utility Model Content

[0015] In response to the deficiencies of the prior art, the utility model provides a high-pressure water spraying device for a concentration tank with an anti-splashing function. The device uses a proximity switch SQ to control the opening and closing of a solenoid valve on a water spraying pipe. When the rake of the rotating device rotates to the spraying position below the high-pressure nozzle, the solenoid valve installed on the water spraying pipe is used to close the water spraying pipe in time. After the rotating device leaves the spraying position below the high-pressure nozzle, the solenoid valve is reopened and the high-pressure nozzle continues to spray.

[0016] See Figure 1 The utility model mainly includes a proximity switch SQ, a water spray pipe 2, a solenoid valve V, a high-pressure nozzle 4, a trigger block 3, and a hanging device 1. The water spray pipe 2 and the high-pressure nozzle 4 are located on the upper part of the high-efficiency concentrator, the water inlet end of the water spray pipe 2 is connected to the high-pressure water source, and the high-pressure nozzle 4 is connected to the water outlet end of the water spray pipe 2. The solenoid valve V is installed on the water spray pipe 2 to control the water flow in the water spray pipe 2, thereby realizing the control of the spray action of the high-pressure nozzle 4; the proximity switch SQ is fixed on the water spray pipe 2, the normally open contact of the proximity switch is connected to the controller of the solenoid valve V, and the trigger block 3 is fixed on the bracket of the hanging device 1 and corresponds to the proximity switch SQ.

[0017] See Figure 2The controller of the solenoid valve V includes an air switch QF, an intermediate relay KA and a contactor KM. The control coil of the intermediate relay KA is connected in series with the normally open contact of the proximity switch SQ and then connected to the power supply through the air switch QF; the control coil of the contactor KM is connected in series with the normally open contact KA-1 of the intermediate relay and then connected to the power supply through the air switch QF; the control coil of the solenoid valve V is connected in series with the normally open contact KM-1 of the contactor and then connected to the power supply through the air switch QF.

[0018] When in use, close the air switch QF and turn on the power, the controllers of the proximity switch SQ and the solenoid valve V are in working state, and when the cage 5 follows the bracket of the hanging device 1 to the spraying area below the high-pressure nozzle 4, the proximity switch SQ fixed on the water spray pipe 2 is triggered by the trigger block 3 installed on the bracket fixed on the hanging device 1, and the normally open contact of the proximity switch SQ is closed, the control coil of the intermediate relay KA is energized, the normally open contact KA-1 of the intermediate relay is closed, the control coil of the contactor KM is energized, the normally open contact KM-1 of the contactor is closed, the control coil of the solenoid valve V is energized, the solenoid valve V is closed, and the high-pressure nozzle 4 stops spraying water mist, effectively preventing a large amount of water from being sprayed onto the rake frame and the cage, causing accidents such as water ingress and short circuit of the electrical circuit and corrosion of the rotating device bracket. When the rotating cage 5 is away from the spraying area below the high-pressure nozzle 4, the trigger block 3 is away from the proximity switch SQ, the normally open contact of the proximity switch SQ opens, the control coil of the intermediate relay KA loses power, the normally open contact KA-1 of the intermediate relay opens, the control coil of the contactor KM loses power, the normally open contact KM-1 of the contactor is disconnected, the control coil of the solenoid valve V loses power, the solenoid valve V opens, and the high-pressure nozzle 4 continues to spray water mist to eliminate the foam in the concentration tank in time.

[0019] Proximity switch SQ uses a magnetic switch, such as a reed switch or Hall-effect switch. Trigger block 3 is a magnet. The position and detection range of proximity switch SQ must be adjusted before use. Multiple trigger blocks 3 are mounted on the bracket of the suspension device 1. By adjusting the distance between each trigger block 3 and the proximity switch SQ, as well as the distribution of the trigger blocks 3, the detection range of proximity switch SQ can be adjusted. This ensures that when the rotating cage 5 moves to the spraying area below the high-pressure nozzle 4, the proximity switch SQ activates the solenoid valve V in a timely manner, preventing high-pressure water from being sprayed onto the rake frame and rotating cage and splashing everywhere. When the rotating cage 5 leaves the spraying area, the proximity switch SQ accurately closes, causing the solenoid valve V to open, ensuring normal water mist spraying.

[0020] The use of this device can greatly reduce the electrical failure rate of the equipment, reduce the frequency of equipment maintenance, eliminate the risk of equipment damage and production suspension, and personnel electric shock, delay the corrosion and aging of the rotating device bracket, extend the service life of the equipment, and enable the equipment to operate efficiently and stably for a long time.
