The present invention relates to a discharging hopper, and more particularly, in storing and discharging a storage such as limestone, quicklime, coal, dust collecting, and the like, regardless of the type and size of the storage. An anti-jamming hopper having a stop screen which prevents the surrounding environment from being contaminated.

Generally, a hopper is a container which is used to collect powders, or powders or lumps, that is, lumps and carry them out using a conveying means such as a conveyor. A hopper can be discharged. This discharge hopper is particularly applied to various powder or aggregate transfer lines such as steel mills to serve to quantitatively distribute and transport lumps of storage such as raw coal, and discharge a certain amount of storage to the next process. In order to transfer, as shown in FIG. 1, the hopper 101 is provided with the gate 103 at the exit side, and by opening and closing the gate 103 in a timely manner, it is possible to adjust the amount of the discharged matter.

However, in the conventional hopper 101, particularly when the storage has a mass of a certain size or more, when the gate 103 is closed after discharging a certain amount of the storage, the mass in the storage and the tip of the gate 103 Since the gate 103 cannot be completely sealed between the inner wall surfaces of the hopper 101, the powder component of the stored material leaks to the outside of the hopper 101 through the gaps, which contaminates the surrounding environment or easily ages the facilities. There was this.

Accordingly, since the hopper 201 and the gate 203 as shown in FIG. 2 were developed, the movable frame 205 is installed below the gate 203, and the movable frame 205 is supported by the support link 207. The upper and lower gaps between the hopper 201 and the gate 203 to be closed upward by closing the gate 203 when the gate 203 is closed. The upper and lower gaps were double sealed. However, also in this case, since the lump of the storage is caught at the tip of the gate 203, a gap is generated between the hopper 201 and the gate 203, and the possibility of damaging the surrounding environment due to the leakage of the storage still remains. (203) When an excessive force is applied during closing, the gate 203 tip, the hopper, or the link 207 may be damaged, and in the long term, it may easily cause deformation.

 Accordingly, the present invention is to solve the problems of the conventional lump dispensing hopper with a stop screen, even if the gate is closed to quantify the discharged discharges in the middle of discharging the storage through the hopper. The purpose of the present invention is to prevent various kinds of contamination and performance degradation caused by leakage of the stored material through the gap generated by preventing the stuck between the inner wall surface of the hopper.

In order to achieve the above object, the present invention provides a hopper in which a storage outlet is opened and closed by a gate which repeats lateral movement, wherein the outlet side of the gate opposite side of the hopper is surrounded by a double case. Provided is a non-stop hopper having a stop screen on which a stop screen is rotatably mounted in a passage connecting the hopper and the auxiliary case.

Hereinafter, a stopper hopper having a stop screen according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The dispensing hopper of the present invention, as shown in Figure 3 to 5 as shown by reference numeral 1, like the general dispensing storage hopper, the outlet 5 at the bottom of the hopper 1 by opening and closing the various kinds of stored by the gate (3) The powder or the aggregate 10 is discharged, and as shown in order to open and close the gate 3, the driving cylinder 43 is mounted on the lower side of one side of the hopper outlet 5, and the push rod of the driving cylinder 43 is provided. (45) While connecting the connecting block 47 of the gate (3) at one end, the other end of the drive cylinder 43 is connected to the lower end of the outer surface of the hopper (1).

Therefore, the gate 3 moves left and right along the gate guide 49 attached to the bottom of the outlet 5 by the expansion and contraction of the push rod 45 to open and close the hopper outlet 5. As shown in more detail, it is installed on a plurality of rolling bearings 53 which are arranged in a line along the wall of the gate guide 49 and fitted to the inner end of the penetrated gate pin 51, wherein the gate pin 51 is The fixing nut 55 is fixed to the wall of the guide 49.

In addition, in the hopper 1 according to the present invention, a passage 9 is formed at the lower end of the opposite side wall surface of the driving cylinder 43, that is, the outlet 5, as shown in FIG. 3. An auxiliary case (7) is placed on the outer wall of the passage (9) to enclose the passage (9), and the stop screen (11) which opens and closes the passage (9) on the outer wall of the hopper (1) above the passage (9). ) Is elastically mounted to pivot.

However, at this time, the stop screen 11 is mounted above the passage 9 of the auxiliary case 7 so as to be pivotable about the screen shaft 13, as shown in more detail in FIGS. 5 and 6. As shown in FIG. 6, the shaft 13 extends below the shaft 13 so as to pivot away from the passage 9 to open the passage 9, and at the bottom of the stop screen 11, a powder screen 57 is provided as shown in FIG. 6. It can be detachably mounted by the bolt 59, the powder screen 57 is used when the storage material discharged from the hopper (1) is a powder, a suitable material such as a rubber plate, a cloth, depending on the type of storage material Can be selected and used. In addition, as shown in FIG. 6, the screen lever 15 is mounted at both ends of the screen shaft 13 so as to be interlocked with the shaft 13, and is also shown in FIG. 3 at the opposite side of the shaft 13 of the screen lever 15. A tension spring 19 is connected which returns the stop screen 11 pushed out by the gate 3 or the reservoir to its original position as if it is, and the opposite end of the lever 15 of the spring 19 is again It is connected to the base 17 protruding from the upper end of the auxiliary case (7).

Here, the screen shaft 13 of the stop screen 11 is axially supported by the bearing bundle 31 so as to be rotatably mounted to the side surface of the auxiliary case 7 as shown in FIGS. 5 and 6. As shown in FIG. 5, the bearing bundle 31 axially supporting both ends of the screen shaft 13 is attached to the shaft flow slot 21 which is formed to be cut vertically long on the side of the auxiliary case 7, and the outer case. A case block 33 forming a recess, a movable block 35 to which the screen shaft 13 is slidably rotated, and a bearing spring 39 fitted to the spring guide 41 to elastically support the movable block 35. ) And so on.

At this time, the case block 33 is in the form of a square ring, the installation hole 61 is inserted into the spring guide 41 is inserted into the upper surface, and for guiding the movable block 35 up and down on the left and right inner surface. The pair of movable rails 37 extend vertically long and are mounted on the flow slot 21 of the auxiliary case 7 by bolts 63. As shown in FIGS. 5 and 6, the movable block 35 installed in the case block 33 to be movable up and down along the movable rail 37 has an axial support hole into which the screen shaft 13 is slidably inserted. (65) is formed through the center portion, a pair of brackets (67) of the cross-sectional shape L-shape protrudes in the center of the upper surface, the bracket (67) as shown in the pedestal ( 69) is fitted and fixed. In addition, a bearing spring 39 for elastically pressing the movable block 35 is inserted between the case block 33 and the movable block 35 around the spring guide 41.

Now, the operation of the anti-locking hopper having a stop screen according to the embodiment of the present invention configured as described above is as follows.

First, as shown in FIG. 3, when the gate 3 is opened for discharging the storage 10, a large amount of the storage 10 passes through the outlet 5 of the hopper 1 below the hopper 1. They are dropped by various containers or conveyors located and transferred to other places. At this time, the stop screen 11 is shown in FIG. 3 because the movable block 35 is positioned at the bottom of the case block 33 by the weight of the screen 11 and the repulsive force of the spring 39 as shown in FIG. 5. As far as possible, it sags downward as much as possible, so that the lower edge portion is positioned below the gate 3.

When the gate 3 is closed in this state, a part of the mass component in the storage 10 is sandwiched between the leading edge of the gate 3 and the screen 11 as shown in FIG. 7A to push the screen 11 to the left. This not only causes the screen 11 to rise above the gate 3 as shown in FIG. 7B, but also a mass of hung on the tip of the gate 3 to be pushed up to the gate 3 together with the screen 11. In this state, most of the storages 10 are pushed into the hopper 1 by the restoring force of the spring 19 acting on the screen 11 through the lever 15, so that it is no longer connected with the gate 3; The storage is not caught or caught between the walls of the hopper 1 to prevent the storage from leaking out of the hopper 1.

In the event that a large amount of force is applied to the screen 11 or the bearing bundle 31 supporting the screen 11 due to the clogged mass 10 between the screen 11 and the gate 3, Since the movable block 35 bearing the shaft 13 moves upward while compressing the spring 39, the force applied to the bearing bundle 31 is mostly attenuated by the spring 39, and thus, the bearing bundle 31. ) Does not cause any damage or deformation.

In addition, when the gate 3 is opened in the state of FIG. 7B, the screen 11 is movable as described above even if the lower portion of the screen 11 comes into contact with the gate 3 surface and the excessive force is applied to the bearing assembly 31. Since it is pushed upward together with the block 35, the bearing bundle 31 is likewise not impacted at all.

As described above, according to the anti-locking hopper having the stop screen according to the present invention, even if the gate for opening and closing the hopper outlet during discharging various sizes of stored matter stored in the hopper is stored between the gate tip portion and the hopper inner wall surface. The lumps in the water do not get stuck and the hopper outlet can be completely sealed. Therefore, as a conventional method, it is possible to prevent the storage powder from leaking out of the hopper through the gap generated by the mass of the storage sandwiched between the gate and the wall, and thus the environment or surrounding facilities around the hopper may be contaminated by the leaked storage. Can be prevented or damaged.
