DE2558702A1 - Silo tanks for granulated material - has V-form tanks placed end to end and connected by common discharge conveyor screw - Google Patents

Abstract

A number of VEE-shaped silo tanks (1-3) are placed side by side so that the parallel silo walls (4,5) are next to each other. A horizontal conveyor screw (7) located at the lowest point of the silos connects the storage chambers of all the silos. The conveyor screw (7) is thus able to discharge the content of any one silo at a common outlet point. The dividing walls (4) between the individual silo chambers are also the positions where the conveyor screw is split into sub-sections. Each silo is provided with its own filler hole cover.

Description

Facility

for the storage of powdery goods and granulates The invention relates to a device for storing powdery goods and granulates with openings for filling from transport vehicles and, or with bagged material, as well as with discharge organs.

Such devices, so-called silos in vertical construction, are known, which can have both round and angular cross-sections and at the lower end have an outlet cone. These silos are usually provided with support legs. The stored goods are transported through a wide variety of discharge devices, e.g. Rotary feeders, screws, pneumatic conveying, etc ... discharged. The filling can be done e.g. pneumatically, via corner corners or bucket elevators or by appropriate Combination of such facilities.

An essential criterion for the selection of the loading device is the type of delivery of the goods, e.g. in silo vehicles or sacks. He follows the delivery in sacks, a sack tear-opener must be attached to the actual loading device, which is also designed as a feed vessel.

The inventor perceives this as time-consuming and disadvantageous.

Another disadvantage of the vertical silos is the fact that the material must first be conveyed up in order to then be used in a substantial amount to be carried out again at a lower altitude.

So-called export-split silos are used for export to distant countries used: Despite this division, it is very bulky goods, their freight costs are very high compared to the total value.

It is particularly useful for portable concreting plants where Cement is used as a powdery good and this is delivered in sacks is dispensed with the silo. The cement comes directly from the bag tearing and Feeding device to the point of consumption. This means that the cement during the Concreting process must be continuously abandoned. Is it a very simple one Sack tearing and feeding device with manual task, this means the Use of additional staff.

The invention is based on the object of a device for storage of powdered goods and granules that have the disadvantages mentioned of the known facilities avoids.

According to the invention, this object is achieved by a device whose longitudinal axis is arranged horizontally, and which consists of one or more individual pieces can be put together. In this way, any capacity reach. The individual pieces are provided with filling openings at the top and through at the bottom one or more discharge organs connected to one another.

Furthermore, the individual pieces of this device consist of side walls, which can converge towards the discharge element and a cover. The end pieces are each additionally provided with an end wall.

These parts can of course be firmly connected to one another by welding will. However, the inventor sees a particular advantage of this device in releasably connecting these structurally simple, large-area parts to one another, to accommodate them in a space-saving manner during transport.

The discharge element can either be a part of all individual pieces Connect devices with each other or in parts assigned to each individual piece, i. be carried out divided.

Furthermore, of course, all individual pieces with end walls can also be used be provided so that they are effective as partitions of the device when assembled will.

In addition, one or more individual pieces with additional equipment, e.g. for tearing open sacks in the form of simple knives in the lid opening or e.g. attached, automatically operating bag tearing machines.

In addition to the easy transport made possible by the horizontal Arrangement of the storage facility created the prerequisite for powdery goods and granulates without a special conveyor, even from those that are not specially equipped Vehicles and bagged material to be handed over to this storage facility.

The following is an example of such a horizontal storage facility described. Figure 1 shows a cross section, Figure 2 shows a side view.

This storage facility consists of the individual pieces (1 to 3), the are releasably connected to each other in planes (4) and (5). The unique piece (2) consists of the side walls (6) which converge towards the trough screw (7) and the lid (8) with a filling opening (9). These three flat parts (6) and (8) be easy on Screwed together in a dust-tight manner. Support legs (1-0) serve to support the individual pieces (1 to 3). The unique pieces (1) and (3), which serve as end pieces in this example, differ from the Single piece (2) through additionally attached end walls (11).

The trough screw (7), which in the example is intended as a continuous screw is, but can also be separable in levels (4) and (5), promotes this stored goods via the outlet (12) into a downstream conveyor device.
