Description

severity Foreign substances such as stones and metal parts must be removed from the liquid manure removed as they are in the tanker pump and / or the distribution organs of the tanker to damage or lead to blockages can.

It are active and passive stone precipitators in use.

active Separators work with sieves, which are the shredded screenings of organic origin by means of rotating knives. The Separator for not crushable, heavy Fremkörper (such as stones) are the Crushers are upstream and are mostly due to their low Volume insufficiently functional.

passive, separators mounted on tankers are equipped with sieve-free calming rooms fixed baffles. Heavy foreign substances remain in front of the Harassment lies.

effectively These separators are only if they are sufficiently large become. But then they cause a high curb weight, since the Separator volume can not be emptied.

Therefore are so far large-volume Separator for coarse heavy materials - for example Stones - outside stationary of the tanker positioned. Stationary Separators are for example However, a contractor can not be used flexibly. The emptying The foreign matter is hereby unpleasant and time consuming. The so far carried along on the tanker Separators are too small to work effectively. When enlarging previous ones, entrained Separator is due to the lack of emptying the Abscheidervolumens the useful volume of the slurry tanker reduced.

The new invention eliminates the disadvantages of entrained separator.

Of the Separator consists of a large-volume chamber. This can carried on the tanker be identical or even identical to a part of the tanker. In the chamber, a movable chicane is installed in such a way that this acts as a chicane when the tanker is filled, but when emptying is ineffective. When folded down, the chicane covers the bottom part of the separator, which then by opening the Lower soil can be emptied. The remainder of the separator is thus available as useful volume. Damage volume is only the sump volume. The improvement of the Abscheidefunktion about by Magnification of the Its volume is thus no obstacle in the way.

image Description

In 1 the arrangement is shown together with a self-priming rotary lobe pump during the intake from a pre-pit. pusher 1 is closed, slide 2 is open. The chicane is folded up. The dotted line shows the path of the main stream of liquid.

Function of the separator:

by virtue of the low flow velocity in the Separator - the Flow area in the separator is many times greater than that in the intake pipe or Intake hose - sink heavy foreign bodies down and gather in the swamp.

When applying liquid manure in the field, the baffle is lowered (see 2 ). The non-contaminated Abscheiderteil above the sump can be emptied by the arrangement of the suction at the bottom of the separator. Only a small part of the separator volume remains on board the tanker. The size of the separator and thus its effectiveness does not affect its curb weight.

This is the essential aspect of the invention.

In 3 the emptying process is shown. The lower part of the swamp consists of a movable flap or is a moving floor. The emptying can be controlled automatically and is usually done at a suitable place in the field.

In 4 is the device with a crushing device according to GM 9107 622.6 or similar design for the comminution of fibrous materials or organic coarse materials, wherein the crusher is usually positioned between the separator and the pump.

Basically the separator also with another pump - for example one not shown self-priming centrifugal pump - operated become.

A further advantage of the device according to the invention is that the operator of a tanker towed by a tractor during Ausbringvorgang can affect the vertical load of the drawbar on the tractor pull eye so that during the Ausbringvorgangs this is reduced to a lesser extent, as it would be the case if no entrained separator is installed. Because of the delayed emptying of the separator contents integrated in the front tank area, the position of the tank truck's center of gravity shifts forward.

In the pictures 5 . 6 and 7 this will be explained.

5 shows the position of the multi-way valves during the filling process and accordingly the course of the slurry flow. When sucking from a pre-pit is sucked through the separator. The chicane is raised. The separator is effective.

6 shows the position of the multi-way valves and the way the manure during the Ausbringvorgang.

tap 2 is closed. tap 1 stands on "suction from the tank" 3 When emptying, initially only the useful volume of the tank is emptied The separator remains filled The function is optional and can be switched off The way of the center of gravity of the tanker runs along the dot-dash line.

The Weight of the still filled Separator causes a shift of the tank car center of gravity forward and has the consequence that the vertical load on the pull eye of the Tractor is always bigger, as with simultaneous emptying of the entire tank car contents. An increased vertical load on the pulling vehicle increases its possible Traction.

7 shows the position of the reusable valves at the end of Ausbringvorgangs when according to the invention, the separator volume is emptied. The center of gravity is now shifting towards the usual center of gravity of the empty tanker. Furthermore, it is conceivable that the device is mounted in a vacuum tanker - see 8th Vacuum tankers accomplish the filling of the tank volume by creating a vacuum in the tank. For vacuum generation, an air compressor is used. By reversing the compressor, an overpressure is generated during the dispensing process in the tank.

At the Vacuum tankers usually remain heavy foreign bodies in the Tank, so it needs to be cleaned from time to time.

By Use of the device according to the invention the deposit can take the heavy foreign matter onto the sump part of the Be limited to the separator which can be emptied automatically, remotely. The currently common, laborious cleaning a vacuum tanker through a manhole can then be omitted.
