Description

[Detailed description of the invention] name of invention FIELD OF THE INVENTION Bins for storage and discharge of free-flowing granular materials The present invention utilizes fluid pressure-driven weighting of the material within the bin after the bin lies on a corner. Concerning bulk storage bins with force evacuation.

prior art Free-flowing granular materials, such as sugar, sand, rice, etc., made from metals and other materials stored or contained in silos or bins with rigid walls and bottoms. Vent are generally formed into silos or bins, such as silos or bins, and when opened, the material spills out. do. From the outlet, the material is transported by a conveying means, for example a screw conveyor. Ru. When the bottom of the silo or bin extends from the outlet to the wall and is flat or horizontal. , all of the free-flowing particulate material will not be expelled from the outlet by gravity.

Free-flowing granular material remaining in the bin When in a diagonal corner, flat or horizontal It has the characteristic that the material contained in the waste at the bottom and the large box will not come out from the outlet.

The material remaining in the bin after gravity discharge forms an inverted cone within the silo . The surface of the free-flowing granular material should be sized at the bottom of the silo with respect to the outlet in the wall. facing upward at an angle to the wall of a bin or box.

The bin has a hopper means for discharging all of the contents of the bin. These ho One means has a side surface extending from the outlet at an angle towards the wall of the bin. potsu The angle at which the bottom of the par protrudes from the bin wall through the outlet is determined by the angle at which the material rests at the corner where it lies. Sufficient to prevent the bin contents from leaking and to direct all of the bin contents to the outlet for removal. It is. The bottom shape occupies a smaller area than a flat-bottomed silo or bin of the same size. Concentrates the weight of the hopper. In addition, the bottom of the hopper is 4, and the large box is the same with a flat bottom. A large box of the same size also has a high center of gravity. Is a large box shaped like a hopper effective? It wastes space.

The idea of using an air-powered flexible membrane inside a container is known (for example, For example, see West German Published Patent Application No. 2705689 (1968)). however , none of such prior art discloses an inflatable double key to the applicant's knowledge. A heavy-walled, flexible bag can be used as a storage bin, with the interior walls movable under pneumatic pressure. [Gravity directs the stored material from the corner where it lies to the outlet in the bag. It does not suggest that the

Next, the contents of the large box are opened. from the conveyor, for example, a screw conveyor (not shown) K. (Different areas can be transferred.) . Free-flowing particulate material continues to flow out of the bin through the outlet due to gravity. to reach or near a lying corner for a particular material. Ru. At the lying corners, the inner surface R of the free-flowing particulate material takes the shape of an inverted cone; The tip of is located at the discharge opening and the discharge of material is stopped.

Air at constant pressure is applied to the inner and outer walls to overcome the corners and complete the evacuation process. Put it in the bag 12 between the two. Bag 12 begins to inflate the top of the bin, and then It begins to swell towards the center of the large box. This expansion creates a free-flowing granular material in an inverted cone Push it near the top of the container and allow gravity to cause it to fall toward the discharge opening. flexible tip The air pressure inside the shaped bag is relatively low, e.g. 0.25-1 psi; Limited resistance caused by a small amount of free-flowing particulate material at the top of the inverted cone is necessary to overcome.

As air continues to inflate the bag, the inner wall 14 will extend further toward the center of the storage area. until full expansion is reached and substantially the entire contents of the bin exit through the evacuation opening. Ru.

The flexible cup-shaped bag 12 is mounted on a stationary member, e.g. an opening 2 in the floor, adjacent to the discharge opening. 6 or anchored to conduit 30. In the embodiment of FIG. 2, it is the conduit 6 0 by a flat tube 64 and a flange 66, said tube 64 and flange 66.

A blower 76' is provided for inflating and deflating the bag, FIG. reference. This blower has outlet twins 78'. This exit line directing the outlet of the inflatable bag 28' through line 86' to inflate the inflatable bag 28'. It has valves 80' and 82' that control whether it is vented to the atmosphere or vented to the atmosphere. do. Or, when you need air pressure, the blower can just turn on. can be done. Line 86' is connected during the emptying cycle or It has a stop valve 88' to prevent the bag from collapsing when the bag is stopped. Bu Connected to the retraction opening 36' back to the inlet of the lower 76' and connected to the valve 90' and There is also a line 87' controlled by 92'. control box 84' controls valves 80', 82', 90' and 92'. have appropriate controls to Also, using the control box , directly controls the activation and deactivation of the blower, thus automatically controlling Some of the valves that are installed can be eliminated. then manually control Inflation or deflation can be selected using the provided valve.

For this control, a commercial Material indicators 94' of the types available in There is a Z-) long level switch made by Engineering. This material indicator The area just outside the normal boundaries where the material is emptied into its lying position. located just adjacent to the discharge opening of the temperature control box 84'. or directly control the blower.

A perforated vacuum hose 96' is located between the walls of the bag 28' at the outer periphery of the bottom; This causes the bag to assume the original position of the contraction quantum.

In practice, the bin 10' of FIG. 7 is used to store bulk materials such as sugar, rice, etc. , initially filled with corn, powder, or grain. This material is free-flowing and It should be of a type that can be handled in a large box.

Figure 15A shows a bin loaded with material. Trying to eject the material from the large box. When the gate 68' is opened by pulling the handle 70', the material is When the material flows out of the bin and exits through the discharge opening, the angle at which it lies Then, it will not cover the sensor of material indicator 94' in the large box. child When , the material is in the state shown in FIG. 15B. When the indicator does not feel the material, Bin level indicator 94' provides a signal to control box 84'. Then, the relatively low pressure from the bag wharf 6' begins to inflate the shiva rug. Ru. The top of the bag 28' begins to inflate against the inner wall 60', as shown in FIG. swells inward.

The material continues to flow and the wall 60' of the bag collapses as shown in FIGS. 15D and 15E. It continues to expand. During ejection, the material expands over indicator 94'. is stopped, the check valve 88' maintains a low pressure, and the Drain by gravity until it no longer covers the water. This cycle It will be restored. Near the end of the emptying cycle, the inner wall 60' of the bag 28' is at the bottom. and lift the remaining small amount of material into the discharge opening, see Figure 9 below.

Probe and/or blower malfunction, with gloves that can mislead the reading of material flow. There is a nearby material leak or a shutoff switch malfunction that causes the bin to be completely emptied. If so, overpressure may occur. Very low contained pressure (0,25-1 psi Accurate, simple and inexpensive pressure for all water gauges (i.e. approximately 15 to 71 steel The release means are shown in FIG. Lines with check valves 114 of the same diameter A manometer 110 is connected to the blower outlet lower 8' via 112. Aerated storage A collection connector 116 surrounds the outer leg of the manometer.The system illustrated is: At 56 cst water, release pressure. Because at high pressure, This is because water is sucked from inside the manometer into the small container.

The reverse valve prevents the vacuum from drawing water into line 78'. Manometer is pressure Water can be easily refilled after a force release call.

Figures 12.13 and 14 show another embodiment.

For various reasons, it may be desirable to provide the supply opening 16' several feet above floor level. Something bad happened. In the embodiment of FIGS. 12 and 13, the honeycomb support Place a temporary floor 90' that can be installed on top of the body 100' to raise the level of the bottom of the large box. Raise it to a point just below the discharge opening 16'.

Figure 14 shows a temporary floor 102' with a tapered floor, opposite the discharge opening. From a point on the floor to a point above the floor and just below the discharge opening. represents another approach to the problem with a par.

The advantage of both the embodiments of FIGS. 12 and 14 is that the exhaust opening is located below floor level. but to lift the relatively heavy weight of the material to be discharged over a significant distance The advantage is that the bag 28' is not required.

FIG. 16 shows another presently preferred embodiment. Substantially the same as in Figure 7 Parts illustrated in the same FIG. 16 have the same reference numerals. For example, FIG. The same double wall sloping upper tip is fastened to the wall by a shaped clamp 68'. It has a shaped bag 28'. Additionally, the embodiment of FIG. 16 has an inflation opening 99'. The expandable tube 97' is shown in greater detail. This inflatable tube or collar The pump 68' extends around the perimeter of the lower bin. The expansion tube 97' prevents slack. are provided for the inner wall 60' of the bag 28'. In this way, this slack can be Adapting the bag to the corrugations of the outer wall 14' is necessary when loading the bag with heavy materials. Ru. It is recommended that such strain be absorbed by the air in the expansion tube 97'. As a result, strain is removed to a large extent from the beam 2 pump 68' and the wall of the bag.

Additionally, inflation tubes 102 and 104' are located at a level above clamp 68'. and with appropriate inflation openings 106' and 105', the inflatable If the top of the bin does not reach the top side of the bin opposite the drain opening, do not drain the material. Further promote.

In the embodiment of FIG. 16, the screw conveyor 106' is Extend radially from the bin at an angle that Exhaust. This conveyor is located below the structure of the temporary floor 108', It also extends at an angle across the floor segment. Wastewater in the floor above the conveyor The exit opening 16' is closed by a manually operated slide gate 110'. stomach The indicator globe 94' is located above the discharge opening 16' and An opening 112' is provided for inspecting and accessing the discharge area.

Implementation of this embodiment is shown sequentially in FIGS. 17A-17D. 17th In Figure A, the bulk material M has been removed from the conveyor 106 When ' is working, it flows at the outlet due to gravity. Clanflow 8' lie Tube 102' is inflated to facilitate evacuation over the tube υ (see Figure 17C). 914' can then be expanded as in FIG. 17D.

In all embodiments, the inner diameter of the inflatable bag is self-cleaning. This is that The bag flexes periodically and the bag is lifted or forced under high pressure. This is believed to be due to the fact that the material always flows due to gravity.

Figures 18A-18F show perforated vacuum tubes or holes during deflation and bin reloading. 9 illustrates the use of a base 96' and an inflatable bag. As seen in Figure 18A , begins deflation and applies vacuum to perforated vacuum hose 96', while at the same time inflatable tube 97' (See Figure 18B). Then the bag gradually returns to its original location. As shown in FIGS. 180, 18D and 18B, the position of Fits perfectly into the corner of a large box.

However, the inner wall bulges and when the bin is loaded, as shown in Figure 18E. and tilt. Figure 18F shows this beveled finish, which extends the interior wall. Adapting the inner walls to the corrugations in the bin walls 14', otherwise the bulk material to be stored When refilling the inner bag, stretch as necessary to fill the bond This is useful when The inflatable collar 97' connects the vacuum to the perforated vacuum hose 96'. can be expanded by the same power source used to add .

In central discharge embodiments (see, for example, Figure 1), a A second sensing glove is placed in a separate hole between the bin outlet and the conveyor. can be made to exist. As shown in FIG. and the valve means 62 (which is also a slide valve located in the discharge opening 22 control). Hotsuno (- means the container that carries away the material. It is supplied to the bearer 162. Probe 164 can be used in side unloading embodiments. It is similar in structure, function and operation to glove 94'.

As is clear from the above, a storage bin for free-flowing granular materials can be easily and inexpensively constructed. The supporting double-walled bag can be inflated with air to ensure even weight distribution across the supporting floor. automatically facilitating the ejection of material beyond the lying angle by stretching A unique hand that pneumatically facilitates the handling and evacuation of free-flowing granular materials. Revealed the steps. 11 Compared to conventional bulk storage and hoppers, the present invention reduces the required Silo size, carrying weight, lifting equipment and costs, floor loads, maintenance and Costs vary significantly.
