Abstract

<P>PROBLEM TO BE SOLVED: To prevent storage material thrown in a hopper from taking a bridge configuration. <P>SOLUTION: To attain the above object, a hopper apparatus of the invention is characterized by the hopper wide at an upper end and having a discharge device at a lower end of an inverted triangular shape in cross section, in which hopper chains installed connectedly with one or more drive devices moving in a reverse direction to a discharge direction of the discharge device and circularly connected are arranged in place in the hopper. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an improvement of a hopper device having a discharge device at the bottom, which is suitable for discharging a stored product having viscosity.

  Conventionally, in a hopper in which, for example, hoppers are received from the upper receiving port and then discharged by the discharging device, the stored material is compacted in a bridge shape between the inclined side walls of the hopper and is naturally directed toward the discharging port side. It may be in a state where it cannot fall. For this reason, a vibrator is attached to the hopper to give vibration to the side wall of the hopper, and a crack is generated in the bridge state so that the discharge to the discharge port is possible. Or the method of giving a shock with an air hammer, an electromagnetic hammer, etc., and canceling a bridge or a rathole, etc. are common.

  However, in the case of stored items with high adhesive strength, they form a nodule, and even if a vibrator is vibrated by a vibrator on the bridge formed by the nodule between the opposite side walls of the hopper, the stored item is not affected by the vibration. There is a problem in that it is further consolidated and further promotes bridge formation, becomes stronger, becomes clogged in the hopper, and is not discharged from the discharge port.

  Further, even in the hopper device configured to be carried out by the screw conveyor, there is a problem in that the lower part of the stored item is scraped off in an arc shape by the tip edge of the rotating screw blade of the screw conveyor and a bridge is formed. The object of the present invention is to provide a storage hopper device that does not cause such a bridging phenomenon.

  In order to achieve the above object, the hopper device of the present invention has one or more hopper devices that have a wide upper end and a discharge device at the lower end of an inverted triangle and move in the hopper in the direction opposite to the discharge direction of the discharge device. A hopper device characterized in that a chain connected to a drive device of a book and connected in an annular shape is arranged at a proper position in the hopper.

  By moving the chain horizontally in the direction opposite to the discharge direction of the discharge screw in the hopper where the discharge screw is provided at the bottom, the position where the bridge is generated due to the nature of the stored item, and the area where the arch load is concentrated Cut the place where the load is concentrated, and it will fall to the discharge port side by its own weight.

  Also, since the chain moves in the horizontal direction, it does not consolidate the storage.

  An embodiment of the present invention will be described with reference to the drawings. In a hopper 1 having a wide upper end, a cross-section of an inverted triangle, an input port 3 at the top, a discharge device 2 at the bottom, and a discharge port 4, a drive device 5, a drive wheel 6, and a return Endless chains 8 and 9 connected to the wheel 7 are installed horizontally.

  Since the chain 8 rotates in the direction opposite to the direction of compression of the discharge screw 2, it does not consolidate the store.
