DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0020] Embodiment of the utility model: a flange type feeder, such as Figure 1-4 As shown, it includes a cylinder 1, the upper and lower ends of the cylinder 1 are respectively a feed port and a discharge port, a fixed flange 2 is welded and fixed inside the cylinder 1, the size of the fixed flange 2 is equal to the cross-sectional size of the cylinder 1, a movable flange 3 is arranged below the fixed flange 2, the movable flange 3 is supported on a support 4 in the cylinder 1, and multiple groups of discharge ports 5 with the same structure and position are displayed and distributed on the fixed flange 2 and the movable flange 3, two open grooves are arranged on the cylinder 1 at the corresponding position of the movable flange 3, two rotating handles 6 are fixedly arranged on the side of the movable flange 3, and the two rotating handles 6 extend from the open grooves to the outside of the cylinder 1, and two sets of electric mechanisms 7 are arranged on the outer wall of the cylinder 1, and the output end of each set of electric mechanisms 7 is fixedly connected to the rotating handle 6 via a hinge structure 8, and the tail of the electric mechanism 7 is also fixedly connected to the outer wall of the cylinder 1 via the hinge structure 8.

[0021] A low material level monitoring switch 9 and a high material level monitoring switch 10 for controlling the discharge material layer are also provided on the outer wall of the cylinder 1 below the movable flange 3. The low material level monitoring switch 9 and the high material level monitoring switch 10 are used to monitor the amount of material inside the cylinder 1 below the movable flange 3, thereby controlling the rotation angle of the movable flange 3 and controlling the amount of material discharged.

[0022] The surface of the fixed flange 2 is provided with a scraper cleaning device 11, which is connected to the push rod of the cleaning cylinder 12. The cleaning cylinder 12 is fixed on the outer wall of the cylinder 1. The scraper cleaning device 11 includes a push rod, and two parallel scrapers are arranged at intervals at the bottom of the push rod. The scraper cleaning device 11 is controlled by the cleaning cylinder 12 to move back and forth on the fixed flange 2, so that the materials on the fixed flange 2 can be pushed into the discharge port 5 of the fixed flange 2. At the same time, when some block materials are stuck in the discharge port 5 of the fixed flange 2, the scraper cleaning device 11 can also be moved back and forth to push the block materials out of the discharge port 5 of the fixed flange 2 to prevent the block materials from blocking the discharge port 5 of the fixed flange 2.

[0023] A pneumatic valve 13 is provided at the feed inlet at the upper end of the cylinder 1. When the pneumatic valve 13 is opened, the material can fall into the upper cavity of the cylinder 1 from the discharge pipe with a smaller diameter through the opened valve for unloading. When the discharger fails and needs maintenance, the pneumatic valve 13 can be closed to facilitate maintenance of the discharger.

[0024] An inspection door 14 is provided on the cylinder 1 above the fixed flange 2 to facilitate maintenance and inspection of the feeder.

[0025] A limiting axis 15 is provided at the bottom center of the fixed flange 2, and the limiting axis 15 is inserted into a limiting hole 18 at the center of the movable flange 3, so that the movable flange 3 can only rotate around the limiting axis 15, thereby preventing the movable flange 3 from moving horizontally to the left and right.

[0026] Two mounting blocks 16 are provided at the bottom of the movable flange 3 where the discharge port 5 is not provided. The mounting blocks 16 are provided with mounting holes 17. The rotating handle 6 extends into the mounting holes 17 and is fixed by screws to achieve a fixed connection between the rotating handle 6 and the movable flange 3.

[0027] There is a gap of 1.5 mm between the fixed flange 2 and the movable flange 3 to prevent the movable flange 3 from contacting the fixed flange 2 when rotating.

[0028] The electric mechanism 7 is an electric push rod or a cylinder. When the electric push rod or the push rod of one set of the electric mechanism 7 is retracted, the rotating handle 6 connected thereto can be driven to rotate, thereby driving the movable flange 3 to rotate. At the same time, the electric push rod or the push rod of the other set of the electric mechanism 7 is pushed out with the rotation of the other rotating handle 6. Since the push rod of the electric push rod or the push rod of the cylinder moves linearly, and the rotating handle 6 rotates, in order to be able to drive the rotating handle 6 to rotate through the linear movement of the push rod of the electric push rod or the push rod of the cylinder, a hinge structure 8 is provided at the connection end of the electric mechanism 7 and the rotating handle 6, and the tail of the electric mechanism 7 is connected to the outer wall of the cylinder 1 through the hinge structure 8.

[0029] A sliding seal is arranged at the opening groove of the cylinder body 1 and rotates with the rotating handle 6 to prevent leakage of material from the opening groove.

[0030] The feeder is composed of a pneumatic valve 13, a feed inlet, a barrel 1, an inspection door 14, a scraper cleaning device 11, a fixed flange 2, a movable flange 3, a rotating handle 6 and an electric mechanism 7 connected thereto, a discharge port, a material level monitoring switch (including a low material level monitoring switch 9 and a high material level monitoring switch 10), etc. The pneumatic valve 13 is connected between the material layer and the feeder by bolts, and is sealed with a sealing material as a pressure strip; the scraper cleaning device 11 is connected and fixed to the barrel 1 through a cleaning cylinder 12; the fixed flange 2 is welded inside the barrel 1; the movable flange 3 is supported on the support 4 inside the barrel 1, and the dynamic and static flanges are matched through a gap stop, and a gap of 1.5 mm is retained.

[0031] During use, the pneumatic valve 13 is opened, and the material falls into the upper cavity of the cylinder 1 from the discharge pipe with a smaller diameter through the opened pneumatic valve 13, and the movable flange 3 is driven to rotate by the electric mechanism 7, and the rotation adjustment range is the arc range formed by the discharge port 5 on the flange. The overlap amount of the discharge port 5 on the fixed flange 2 and the movable flange 3 is adjusted to achieve the control of the adjustment of the discharge amount. When the discharge ports 5 on the fixed flange 2 and the movable flange 3 are completely overlapped, the discharge amount is the largest. When the discharge ports 5 on the fixed flange 2 and the movable flange 3 are completely staggered, the material cannot be discharged. When the material layer falling into the downstream equipment is higher than the normal required material layer, the movable plate of the high material level monitoring switch 10 is lifted by the moving material, and the high material level monitoring switch 10 is disconnected. At this time, the electric mechanism 7 drives the movable flange 3 to rotate in the opposite direction, so that the overlap of the discharge port 5 is reduced, and the material passing amount is reduced. When the material layer is lower than the normal material layer or the material is cut off, the low material level monitoring switch 9 is closed. At this time, another set of electric mechanisms 7 drives the movable flange 3 to rotate forward, so that the overlap of the discharge port 5 is increased, and the material passing amount is increased. If the low material level monitoring switch 9 is not disconnected within 5 seconds, the scraper cleaning device 11 starts to operate the cleaning operation until the low material level monitoring switch 9 is disconnected and the scraper cleaning device 11 stops. After the unloading operation is completed, the pneumatic valve 13 of the feed is closed. After the downstream equipment is free of material, the inspection door 14 is opened to manually clean up the large pieces of material staying on the fixed flange 2.
