Example 1

The improved unpowered closed chute for the coal feeder with large coal water vibration adopts the following structure:

as shown in fig. 2, the anticorrosive water diversion device for the coal feeder comprises a drainage slideway 1 laid on a chute bottom plate of the coal feeder, a drainage mechanism is arranged at the liquid outlet end of the drainage slideway 1, a drainage groove 2 is arranged at the liquid outlet end of the drainage mechanism, the drainage groove 2 is installed on a belt frame, and a drainage pipe 3 is connected to the bottom of the drainage groove 2; drainage mechanism is including articulating the cambered surface type flashboard 4 at the feeder exit end, and pneumatic cylinder 5 is installed to feeder exit end both sides, the both sides that are close to the one end of articulated shaft of cambered surface type flashboard 4 are connected with the flexible end of pneumatic cylinder 5 respectively, and the one end that keeps away from the articulated shaft behind the cambered surface type flashboard 4 closure is located the top of drainage groove 2.

Furthermore, the drainage groove 2 is semi-cylindrical and is formed by welding semicircular pipe fittings.

Furthermore, the drainage slideway 1 is a stainless steel lining plate. The material is resistant 304 or 316L stainless steel, and the material is fully welded inside the coal feeder according to a special process. Meanwhile, the welding seam also needs to be specially processed to ensure that coal water in the coal feeder does not contact with common main materials of the equipment.

The drainage slideway 1 is laid with a stainless steel lining plate on the bottom plate of the chute to increase the smoothness of drainage. When the drainage function of the cambered gate 4 is mainly closed by the upper gate, coal water seeps out from a gap between the gate and the slide way (coal cannot seep out), and the part extending out of the slide way introduces the coal water into the drainage groove (the angle and the size of the cambered gate 4 are controlled well). The cambered surface type flashboard 4 is controlled by electro-hydraulic pressure, and unmanned and remote operation is realized. The drainage groove 2 is formed by welding semicircular pipe fittings and is fixed on the belt rack. The water conduit 3 is made of a common seamless steel pipe and guides coal water into the sewage of the industrial area for collection and discharge.

Further, the drainage groove 2 is cuboid.

Furthermore, the drainage plate 7 is wide at the top and narrow at the bottom and is led into the drainage groove.

Furthermore, the drainage slideway 1 is a stainless steel lining plate. The material is resistant 304 or 316L stainless steel, and the material is fully welded inside the coal feeder according to a special process. Meanwhile, the welding seam also needs special treatment to ensure that the coal water in the coal feeder does not contact with the common main materials of the equipment.

The drainage slideway 1 is used for paving a stainless steel lining plate on the bottom plate of the chute to increase the smoothness of drainage. The arc-shaped anti-corrosion flow guide lug 6 is mainly used for guiding coal water, is manufactured integrally with the flow guide slide way in actual manufacturing, and avoids water seepage at a welding seam to reduce the service life of the flow guide device. The drainage plate 7 acts to close up the coal water drained from the coal feeder, and the coal water is wide at the top and narrow at the bottom and is made of a 10mm steel plate and led into the drainage groove. The drainage groove 2 is welded into a rectangular weldment by a steel plate and is fixed on the lower side of the coal feeder. The water conduit 3 is made of a common seamless steel pipe and guides coal water into the sewage of the industrial area for collection and discharge.

The working principle is as follows: the vibration coal feeder is provided with a gate plate, and the coal feeding is controlled by a remote control gate plate. Coal water seeps out from a gap between the gate plate and the coal feeder side plate, is guided to the drainage plate 7 through the water guide slideway 1 and the arc-shaped anti-corrosion flow guide lug 6, and is discharged outside through the drainage pipe 3 after being collected by the drainage groove 2.

The utility model discloses anticorrosive drainage device of feeder is fixed, does not need artifical manual operation to operate. The design of the device realizes coal-water separation, and the workload of workers cannot be increased due to the fact that coal falls into the drainage grooves. The coal feeder with large coal water is provided with the motionless closed chute, so that the feeding is fast, more importantly, the coal water is discharged in time and cannot be deposited in the coal feeder to corrode equipment, the service life of the coal feeder is prolonged, and the workload of staff for maintenance and repair is reduced. The design of the drainage device focuses on the selection of a drainage slide way, the material of a lining plate of the coal feeder, the drainage angle, the shape and the control.

The arc-shaped drainage or arc-shaped drainage is selected according to different equipment, and the coal water can be accurately guided to flow in the correct direction in real time in a fixed or movable mode.
