[0002] Raw materials such as sinter, lump ore, and pellets required for blast furnace smelting are transported by belt conveyors. The conveying direction of the materials is usually changed by boat-shaped flaps. It is difficult for such flaps to simultaneously divert the material to two directions and supply it at the same time.

[0003] The existing Chinese patent application document with publication number CN209905834U discloses a material distribution device that can persistently achieve equal material feeding, including a three-way material distributor and a flip-plate positioning device; the three-way material distributor consists of a three-way chute, a material distribution flip plate, a shaft, a crank, an electro-hydraulic push rod, and a flip-plate positioning device; the flip-plate positioning device is located on one side of the electro-hydraulic push rod and consists of a lower limit position proximity switch, an initial position proximity switch, and an upper limit position proximity switch.

[0004] In the existing technology, both sides of the flap are material-facing surfaces and are subject to material scouring. Both sides need to be lined with wear-resistant plates, and the bolts fixing the plates also need to be wear-resistant. The bolt fixing causes interference, making it difficult to fix and prevent wear, and maintenance and replacement are inconvenient. There are areas for improvement. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a diversion and transfer funnel.

[0006] According to the present invention, a diversion and transfer funnel includes a funnel body, the funnel body having at least one inlet and two outlets, a flap being mounted inside the funnel body via a rotating shaft, the face of the flap facing the inlet being the material-facing face, and the flap being located above one of its outlets; it also includes a linear reciprocating drive mechanism, a proximity switch group, and a sensor, the output end of the linear reciprocating drive mechanism being hinged to the flap, the linear reciprocating drive mechanism driving the material-facing face of the flap to rotate around the rotating shaft at a certain angle to completely or partially close the outlet located below the flap, the sensor being mounted on the flap, and the proximity switch group cooperating with the sensor to measure the rotation angle of the flap; a funnel insert plate is detachably mounted at the other outlet.

[0007] Preferably, the proximity switch group is located on the side of the flap away from the receiving plate, and the proximity switch group includes a plurality of proximity switches spaced apart in the horizontal direction.

[0008] Preferably, the proximity switch group includes at least a first proximity switch and a second proximity switch; when the sensor triggers the first contact switch, the flap completely closes the discharge port located below the flap; when the sensor triggers the second contact switch, the flap is in a vertical state, and the discharge port located below the flap is in an open state.

[0009] Preferably, the proximity switch group further includes a third proximity switch and a fourth proximity switch, which are disposed at an interval between the first proximity switch and the second proximity switch.

[0017] 1. This utility model uses a proximity switch group and a sensor to measure the rotation angle of the flap, which facilitates the control of the opening of the discharge port located below the flap.

[0028] Sensor 6 Detailed Implementation

[0029] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0030] like Figure 1 As shown, a diversion and transfer funnel according to this utility model includes a funnel body, which includes at least one inlet and two outlets. A flap 2 is mounted inside the funnel body via a rotating shaft 1. The surface of the flap 2 facing the inlet is the receiving surface, and the flap 2 is located above one of its outlets. It also includes a linear reciprocating drive mechanism 3, a proximity switch assembly, and a sensor 6. The output end of the linear reciprocating drive mechanism 3 is hinged to the flap 2. The linear reciprocating drive mechanism 3 drives the receiving surface of the flap 2 to rotate around the rotating shaft 1 at a certain angle, completely or partially closing the outlet located below the flap 2. The sensor 6 is mounted on the flap 2, and the proximity switch assembly works with the sensor 6 to measure the rotation angle of the flap 2. A funnel insert plate 4 is detachably installed at the other outlet.

[0031] One side of the flap 2 is the material-facing side. Only a wear-resistant liner needs to be laid on the material-facing side of the flap 2. Compared with the prior art where wear-resistant liners are laid on both sides of the flap 2, the technical solution of this application is more convenient for maintenance and replacement.

[0032] The technical solution of this application uses a proximity switch group and a sensor 6 to measure the rotation angle of the flap 2, which facilitates the control of the opening of the discharge port located below the flap 2. Furthermore, the funnel insert plate 4 can be used to close or open the other discharge port, thus enabling the opening of one discharge port, the closing of the other discharge port, or the opening of both discharge ports. This allows for simultaneous diversion and feeding of materials in two directions.

[0033] Specifically, a proximity switch group is located on the side of the flap 2 away from the receiving plate, and the proximity switch group includes multiple proximity switches spaced apart in a horizontal direction. The proximity switch group includes at least a first proximity switch 8 and a second proximity switch 11. When the sensor 6 triggers the first contact switch, the flap 2 completely closes the discharge port located below the flap 2; when the sensor 6 triggers the second contact switch, the flap 2 is in a vertical state, and the discharge port located below the flap 2 is in an open state. The proximity switch group also includes a third proximity switch 9 and a fourth proximity switch 10, which are spaced apart between the first proximity switch 8 and the second proximity switch 11.

[0034] It should be noted that this application can set multiple proximity switches at equal intervals between the first proximity switch 8 and the second proximity switch 11. Based on the sensor 6 triggering the contact switches at different positions, the rotation angle of the flap 2 is determined, thereby determining the opening of the discharge port located below the flap 2. This allows for the adjustment of the material flow rate at both discharge ports according to production needs during simultaneous diversion feeding.

[0035] The rotating shaft 1 is mounted on the upper end of the flap 2. The hinge point between the output end of the linear reciprocating drive mechanism 3 and the flap 2 is located on the side of the flap 2 away from the receiving plate, and the position of the hinge point between the flap 2 and the linear reciprocating drive mechanism 3 is consistent with the material flushing position on the receiving surface of the flap 2. The rotating shaft 1 in this application has minimal or no contact with the material, reducing the probability of shaft breakage and preventing material jamming. The hinge point between the linear reciprocating drive mechanism 3 and the flap 2, i.e., the point of force application, is far from the rotating shaft 1 and is consistent with the material flushing point, resulting in a smaller torque on the rotating shaft 1 of the flap 2, making it safer and more durable. Furthermore, the linear reciprocating drive mechanism 3 includes a hydraulic cylinder.

[0036] A chute is provided on the side wall of the discharge port equipped with the funnel baffle 4. The chute extends downwards at an angle from the discharge port equipped with the funnel baffle 4 to the discharge port below the flap 2. The inlet of the chute inside the discharge port equipped with the funnel baffle 4 is located above the funnel baffle 4. A chute baffle 5 for sealing the chute is detachably installed inside the chute. When it is necessary for the discharge port below the flap 2 to discharge material separately, the other discharge port can be completely sealed by the funnel baffle 4. Material that accidentally falls into this discharge port can overflow into the discharge port below the flap 2 through the chute.

[0037] Both adjacent upper sidewalls of the two discharge ports include inclined surfaces 7, and each inclined surface 7 extends from top to bottom into the discharge port. The inclined surfaces 7 facilitate the entry of materials into the discharge ports.

[0038] To facilitate understanding, this application provides a specific implementation method:

[0039] When the discharge port below the flap 2 needs to be fed separately, drive the flap 2 to rotate to fully or partially open the discharge port below the flap 2, completely close the other discharge port through the funnel insert plate 4, and remove the chute insert plate 5. At this time, the material can only be discharged from the discharge port below the flap 2.

[0040] When the other discharge port needs to be fed separately, drive the flap 2 to rotate to completely close the discharge port below the flap 2, take out the funnel insert plate 4 to fully open the other discharge port, and insert the chute insert plate 5. At this time, the material can only be discharged from the other discharge port.

[0041] When both discharge ports need to be fed at the same time, drive the flap 2 to rotate and fully or partially open the discharge port below the flap 2. Take out the funnel insert plate 4 and fully open the other discharge port, and insert the chute insert plate 5. At this time, the material can be discharged from the two discharge ports, and the flow rate of the two discharge ports can be adjusted by controlling the angle of the flap 2.
