DE2936412A1 - Loader for dust free transfer of bulk material - has closure cone opened by actuator when open and by weight when closed vehicle is loaded - Google Patents

Abstract

The loader assembly is intended for transferring bulk material to an open or closed vehicle without spreading dust. It comprises a closure cone (1) with an actuator (2) which is capable of opening the cone when used above an open vehicle. The actuator is suspended from a cable (5) via a cross-bar (3) and bracket (4). This bracket may have slots (6) for the cross-bar, which permit the cone to open under its own weight without using the actuator when the assembly is lowered on to the inlet connection of a closed vehicle.

Description

LOCKING CONE FOR LOADING SET

The invention relates to a locking ball for loading fittings for dust-free loading of open and closed transport vehicles with dusty Bulk solids.

The handling of dusty bulk goods in open or closed transport vehicles has always been problematic, as the bulk material transfer is very dusty connected is. There are known loading devices that consist of two concentric to each other arranged pipes or pipe-like bellows exist. Through the inner tube or The bulk material is guided through the inner bellows and through the space between the inner tube and the outer tube or

The outer bellows is when the debris hits the loading area resulting dust is sucked off. The same problems occur when filling closed Container, as dust is stirred up inside these containers and the growth The dusty air escapes from these containers according to the contents. Here too dedusting is required in the same way. After loading, such Loading devices are usually pulled up using a cable winch. This inevitably occurs a residual amount of dust from these sets, and in order to avoid this, be such loading devices closed with an end cone before being pulled up.

Before loading, these sets are fitted with a on the outer jacket Cone placed on the filler neck of the vehicles to be filled. By its own weight of the closing cone, this is then lowered so far that the free bulk material outlet is made possible from the loading set.

So far, this has not been possible when loading open vehicles, because the loading sets are constantly suspended from ropes must in order to enable a free discharge of bulk material below the clothing and around the constantly growing mountain of bulk material in the vehicle to be loaded Adjust the floating height of the loading set or the outlet connection to this set. When the loading process is completed, the loading equipment is pulled up.

It takes a trickle of the residual material and that contained therein Dust in purchase. Sealing cones are not found on such loading devices.

If you now take the trickling down of the remaining material to be conveyed and the associated Soiling of the vehicles and the environment in purchase, it is quite possible with one loading device both open and closed container vehicles to load.

However, if you don't accept this pollution, you need it a loading set that is suitable for both open and closed transport vehicles Silo and transport vehicles are suitable, but in both Cases can be sealed with a closure cone.

According to the invention this problem is solved in that in the closure cone a drive device is arranged, which has a traverse and a bracket is connected in a known manner with a rope suspension.

When loading open vehicles, there is no need to put the filling cone on possible. The set is now lowered so far that the filler neck is above the loading area of the vehicle to be loaded has arrived.

Then the locking cone is so far via a separate drive lowered so that the free exit of the bulk material to be loaded is made possible. In this state, the loading set is above the one already filled in a vehicle Bulk goods can move freely.

The cone remains open until it passes through the drive device is closed again.

Both actuating cylinders and spindle motors are used as drive devices in question.

In a preferred embodiment, the closure cone is on one Traverse attached, which is hung on just one rope by means of a bracket. Through this can be used when filling transport vehicles with a filler neck without actuation the drive of the locking cone via a SchTitz in the bracket of the rope suspension be lowered.

The advantages associated with this are obvious, because without actuation the drive device for the closure cone can be the loading set in the usual Way to be used for filling transport vehicles. Even with defects or if this drive fails or if there is a malfunction, the loading device can at least can be used trouble-free in the usual way for this case. The additional drive is actually only required when loading open vehicles and offers here the advantage that once a clean take off after the loading process is possible and that this loading device is for both closed and open Vehicles can be used.

The invention is based on the drawing showing them as an example described in detail.

The illustration shows the lower area of a loading set. By the inner tube is guided by the bulk material to be loaded and through the ring cross-section between the inner tube and the outer jacket or the cone on the outlet nozzle Dust air extracted. The closure cone 1 closes both the inner tube and the cone of the outer jacket. In this state, the loading device can be in any intended height. If drive 2 is now operated, the Drive device with the locking cone together down and gives both the Opening of the inner and outer pipe is free. Even in this state, the Loading set can be moved at any desired height.

If this loading set is now with the funnel-shaped lower part of the outer jacket (filling cone) on a filling nozzle of a container placed, the bracket 4 hanging on the rope 5 can come together in the area of the slot 6 can be moved further down with the cone 1. That is, the cone gives that Free filling cross-section without actuating the drive located therein got to.
