As we all know, apron feeder is generally divided into heavy, medium and light three kinds, is commonly used in concentrator feeding equipment, widely used from storage bin to crushing, transportation and other machinery for uniform continuous feeding.
Heavy-duty chain apron feeder, which roughly includes auxiliary hopper, observation window, main hopper and feeding mechanism, feeding mechanism includes chain plate, hydraulic powertrain, drive shaft, drive gear, support wheel, chain, driven shaft and driven wheel, drive gear is fixed and inserted in the drive shaft, the drive shaft is arranged on one side of the feeding mechanism, The driven shaft is fixed connected to the other side of the feeding mechanism, the driven wheel is connected to the driven shaft, the chain is fixed to the inner wall of the chain plate, the chain plate is connected to the drive gear and the driven wheel through the chain sleeve, the middle of the drive gear and the driven wheel is provided with a support wheel, the support wheel is rolling connected to the inner wall of the chain plate, the hydraulic power train is connected to the drive shaft, the outside baffle of the feeding mechanism is connected with an observation window, A main hopper is arranged above the observation window, and the main hopper is bolted to the top of the outside baffle plate of the feeding mechanism. Although the above existing technical solution has large output, large output torque and high conveying efficiency, in the process of conveying materials for a long time, the feeder operation generates a lot of heat, and the continuous conveying of large weight materials causes load to the feeder. The above existing technology is not convenient for cooling the feeder, which may cause thermal deformation of the feeder. At the same time, the service life of the feeder is reduced, so it is necessary to design an apron feeder cooling structure.
(1) Technical problems solved
Aiming at the deficiency of the prior art, the utility model provides an apron feeder cooling structure to solve the problem that the prior art proposed in the background technology is not convenient to cool the feeder.
(2) To realize the above purposes, the utility model provides the following technical schemes: The apron feeder cooling structure comprises the apron feeder body, the apron feeder body is provided with a frame, also comprises a chiller and a cold water tank, the internal frame is connected with a cooling pipe through a plurality of slots, both ends of the cooling pipe and the chiller are connected. The interior of the frame is equipped with a plurality of cooling fans through a rotating rod rotation, and the frame is connected with a driving mechanism for driving the cooling fan rotation, the top of the cold water tank is connected with a water pipe, the cold water tank is connected with a water pump, the water pump is connected with a spray pipe, the spray pipe is connected with a plurality of nozzles, The sprinkler pipe and sprinkler head are located below the apron feeder body, and the apron feeder body is provided with a water absorption component.
The driving mechanism comprises a motor, the motor is installed on the frame, the output end of the motor and the corresponding rotating rod are fixed connected, the rotating rod is fixed with a drive gear, the internal frame through the rotating shaft rotation connection has a plurality of driven gear, and the driven gear and the two adjacent driving gear mesh.
The water absorption assembly comprises a fixing plate, the top of the fixing plate is connected with a clamping plate through a plurality of clamping springs, the top of the clamping plate is detachable connected with a plurality of water absorption sponges, and the water absorption sponge is in contact with the bottom end of the apron feeder body.
Cold water is sent to the inside of the cooling tube through the chiller to cool the cooling tube, thus cooling the internal air of the frame. Multiple cooling fans are driven by the driving mechanism to rotate, and the cooling fans blow cold air to the apron feeder body to cool it. The cold water in the cold water tank is drawn out by the pump and sprayed on the bottom of the apron feeder through the nozzle to further cool it. The apron feeder body is dried by the water absorption component to avoid affecting its normal use. Compared with the above prior art, the solution is convenient for cooling the feeder.
