Abstract

The invention concerns a device for producing a stream of bulk material, which device is designed so that bulk material is introduced through a pipe axially into a rotating pot(1). Owing to acceleration and centrifugal force the bulk material moves toward the edge region of the pot(1) and fills the entire pot up to the axial inlet. In the edge region of the pot(1) a blade(12) disposed on a non-rotating part of the pot(1) dips into the rotating material cake in the opposite direction to the rotation thereof, so leading the stream of bulk material out. The device can be used wherever bulk materials have to be measured and metered. The device is flanged directly onto the outlets of existing silos.

Description

Produce and pour into logistics continuously and detect the device that it carries intensity or metering

The present invention is applied in weighing-measurement technology and relates to one be used in particular for detecting the conveying intensity of pouring into logistics that forms continuously and/or the device of metering, belongs to the technical field of claim 1 preamble.

Disclose a hydro-extractor by DE-OS3634994, wherein, the liquid that separates from suspending liquid then is recovered by the device of outside at the kinetic energy that the drum barrel circumference that rotates is removed wherein maintenance.But such device cannot be applied to pour into thing.

At a known device (CH-PS362542) that is used for pouring into the quality testing survey, this pours into thing and is delivered on the rotating disc with the Z-axis rotation by an input funnel, and this transfer position herein, is scraped from device by one and is scraped from rolling disc by delivery to a drain position thus.This rolling disc is placed on the weighing device, just can detect the weight of pouring into thing that is positioned on this rotating disk with it.This device only has a limited measuring accuracy and relative its conveying intensity that can pass through to have excessive physical dimension.

Therefore, become task of the present invention in order to realize a small construction size, that is produce the high-speed stream (water jet of a similar nozzle) that pours into for a short time, then, it finally can point to a suitable measurement mechanism.This measurement mechanism make pour into circulation to, and detect according to consequent centrifugal force and to carry intensity, it is used to metering and pours into thing.

Above-mentioned task is solved by the feature scheme of claim 1.Favourable constructional variant is obtained by dependent claims.

Suitable measurement mechanism is exactly known circulation measurement mechanism and have crooked runner or crash panel in pouring into the thing technology, its may command pour into logistics (as DE2947414 disclosed).

Another measurement mechanism is open in DE3717615.In addition, just can make in the present invention by the wherein disclosed measuring wheel of configuration suitably and pour into logistics and act directly on the measuring wheel.

Be used to make a device regulation of pouring into the thing jet, this pours into thing and inserts in the alms bowl body of a rotation on axially by a pipe fitting.This pours into thing because accelerating effect and centrifugal force and to the fringe region motion of alms bowl body and finally fill up this whole alms bowl body and until axial import.

A cutter of settling on the part of going in ring of alms bowl body pours into the discharge of thing jet to slip into alms bowl body fringe region and therefore to make with the cake material reverse direction ground that rotates.

The advantage of Shi Xianing and being characterized as like this:

Apparatus of the present invention are set to the structure of closed container.

Even if pour into thing powder and can environmentally safe ground and enough measured accurately or measure until very little particulate.

This device does not need flexible connection, and this being connected will cause in the known metering system that pours into the thing measuring technique and ventilate and the pressure compensation problem.

This device has a very little structure height.

It is applicable to directly and is installed in the silo outlet of structure side in the flange mode, but also can be supported on the bottom.

This pours into the product stream that the thing jet pulsed can not occur and show a high stable.

This device is one directly to be measured and regulating device fast, and because the high thing speed of pouring into, thereby does not almost have rest time (for example, 10m/sek, meter per second) during work.

This measurement mechanism has little dimensions for negotiable conveying intensity.

The explanation of embodiment

Fig. 1 is the vertical cross-section diagram by the embodiment of the invention, its have be connected with a silo pour into the thing conveying device;

Fig. 2 is the cross-sectional view by Fig. 1 embodiment;

The device of describing in Fig. 1 is assembled by that rotate and fixing member.The member that rotates comprises alms bowl body 1, and it is vertical and be placed on the axle 4 of a drive motor 11 with flying in circles.A cover piece 2 is along with the alms bowl body rotates, cover piece 2 forms according to the accompanying drawing mold pressing and the ground that descends is slightly settled, this cover piece 2 make pour into thing its from central authorities to alms bowl body marginarium distance restriction and prevent upwards (motion), therefore, this pours into thing and just can controlledly scatter in the alms bowl body.

This lid is being to rise to settle on the marginarium direction of alms bowl body.Therefore, can realize an improved flow characteristics, even and if at this moment, this pours into thing owing to centrifugal force condenses.And favourable effect is, the sidewall that this central cone 5 descends is lengthened out to the fringe region of alms bowl body 1.This is with dashed lines 5 ' description in the drawings.Central cone 5 will vertically flow into from the central point district pours into the direction that thing converts a level to.This center cone 5 is provided with a pore volume and receives driving shaft 4.This central cone has a mixer that is mounted thereon where necessary as pouring into the reinforced assistor of thing (not describing).

This cover piece 2 is connected with the bottom of alms bowl body 1 by being fixedly coupled rib 3.The inward flange of these cover piece 2 relative alms bowl bodies is reserved a slot 6.

Belonging to fixing member has: the housing 8 of encirclement and have the vertical drive motor 11 that connects with flange; Input adapter 9 also has mounting flange 10.This input is taken over 9 and is fixedlyed connected with housing 8 and have a negative mold pressing tapering, that is to say that this input xsect is less than exporting the mode cross section.

In slot 6, cutter 12 dips down and tiltedly slips into, and this cutter 12 is fixedlyed connected with a slide rail 13 with the end of its top.In Fig. 1, this cutter 12 is described as slipping into situation the biglyyest.This slide rail 13 can be in sliding bearing 14 leading.This sliding bearing 14 is to be fixed on the lid inboard of housing 8.Slide rail and sliding bearing 13/14 is so crooked and be obliquely installed, and promptly when slide rail 13 was regulated, the cutter 12 that is connected can be carried out the desired (see figure 2) of moving along the circular wall spare of alms bowl body 1.

Be screwed an adjusting motor 15 on the housing upper surface, it extends in the slide rail 13 with its driving shaft and this slide rail 13 is correspondingly regulated by a right left movement.

In addition, be screwed a vibratory stimulation device 16 on the housing upper surface, its incentive action can reach at the cutter 12 of bottom's motion and make it place vibratory movement.For this purpose, this cutter 12 is connected with slide rail 13 by a vibration metal 17.Just can realize helping to pour into the output (auskopplung) of thing by the excitation of cutter 12.This cutter 12 has one and pour into flowing and shape that friction condition adapts of thing.

The thing that pours into of these outputs just runs into and turns to chute 7, it flatly be bearing in a weighing box 7 ' on.This weighing box 7 ' be fixed on the outside of housing 8.This turns to chute 7 to be suspended on the case lid or to be directly installed on the weighing box by leaf spring.
