Description

The invention relates to devices designed to fill powder materials of long shells, preferably absorbent elements, and can be used in chemical, energy and other industries.

A device for filling containers with bulk material is known, comprising a hopper with a feeder and a metering unit including a filter, a tedder, and also a hollow shaft connected to the vacuum line, at the lower end of which a locking element is rigidly fixed in the form of a funnel expanding downward, while the hopper is mounted on a vibrating platform , the hopper feeder is equipped with a pressure valve, below which and above the expected level of filling with material, the hopper is connected to the hollow shaft, and the filter is mounted on the hopper before entering the vacuum master l.

A disadvantage of the known device is that the entrainment of the fine fraction occurs, as a result of which the efficiency of filling density (shaking) decreases and leads to the need for complex cleaning of the air from the powder coming from the hopper together with the air into the vacuum line.

The closest set of essential features to the claimed invention is a device for filling long shells with powder material containing a vibratory seal, vertically long shells are mounted on the active plate, and a supporting frame is mounted on the passive housing, in the upper part of which are loading funnels for input into the shell of the powder material, while the open upper ends of the long shells are introduced into the boot s funnel.

(see ed. St. USSR No. 1374671)

The disadvantage of this device is that it does not provide the specified technical characteristics, namely, the specified height of the powder in long shells due to the fact that between them and the distribution node there is relative movement during the filling process.

Another disadvantage of this device is that long shells are subject to changes in shape, geometry and mechanical damage due to the fact that during the filling process, long shells interact with the seal assembly in shock mode.

The objective of the invention is to provide a device for filling long shells with powder material, which allows to obtain a given height of the powder in long shells and to exclude changes in the shape, geometry and mechanical damage of long shells.

The problem is solved by creating a device for filling long shells with a powder material, containing a vibratory seal, long shells and a powder material distribution unit, the difference of which according to the invention is that the powder material distribution unit is made in the form of a cup, in the bottom of which there are through holes with the outlets facing out feeders, the bowl is equipped with a guide spline axis, which is rigidly fixed in the central outer part of the bottom, the vibration seal is equipped with It is supported by a support strut mounted on the upper plate of the vibratory seal, made with a splined striker in the upper part, in which the guide splined axis of the bowl is located with the possibility of axial movement, forming a splined joint, while the upper ends of the long shells are coaxially fixed to the outer ends of the feeders and the lower closed the ends of the long shells are located above the top plate of the vibratory seal.

It is advisable that the bowl was made with a central cone, around which through holes are made with the feeders brought out.

It is advisable that the bowl was equipped with pneumatic clamps, in which the outer ends of the feeders and the upper ends of the long shells attached to them are coaxially placed.

It is also advisable that at least one frame with through holes, in each of which a long shell is freely placed, is fixed on the support post.

When the device is operating, a technical result is achieved, namely, that there is no impact on long shells during vibration, which eliminates changes in the shape, geometry and mechanical damage of long shells and provides a predetermined filling height of long shells with powder material.

The specified technical result is achieved due to the fact that during the operation of the device there is no direct contact of long shells with the upper active plate of the vibratory seal, since the upper ends of the long shells are worn on the outer ends of the feeders and secured to them, for example in pneumatic clamps, and the lower closed ends of the long shells are placed along the support column above the upper active plate of the vibration seal.

A device for filling long shells with powder material is illustrated by drawings, in which Fig. 1 shows a general view of the apparatus, in Fig. 2 is a view A in Fig. 1, in Fig. 3 is a vibration seal, in Fig. 4 is a view B in Fig. 3, in Fig. 5 - a bowl for distributing powder material, in Fig. 6 - a top view in Fig. 5, in Fig. 7 - a dispenser, in Fig. 8 - fastening of long shells in a bowl for distributing powder material.

A device for filling long shells with powder material fundamentally (in general form) as shown in FIG. 1 contains a vibration seal 1, a distribution unit for powder material 2, long shells 3 and a dispenser 4.

The vibration seal 1 (Fig. 3) contains a frame 5, a vibration exciter 6, an upper shock plate 7, which is mounted on the frame 5 by means of vibration isolators 8. A vibration exciter 6 is fixed on the bottom 7, and a support strut 9 is provided on top, equipped with a guide splined striker 10 and frame 11 (figure 4) with through holes, in each of which a long shell 3 is freely placed.

The powder material distribution unit (Fig. 5) contains a bowl 12 with an inner cone 13, through holes with open-ended feeders 14 are made in the bottom of the bowl 12. The bowl 12 is provided with pneumatic clamps 15, in which the lower outer ends of the feeders 14 are coaxially located. In the bottom of the bowl 12 rigidly fixed guide spline axis 16.

The dispenser 4 (Fig. 7) consists of a stepper motor 17, a hopper 18, a fastening screw 19, a nepkis 20, a weighing platform 21 and an engine 22, which rotates the powder distributor 23.

On Fig shows a bowl 12 with a feeder 14, on which the long shell 3 is coaxially slid and mounted on it with a pneumatic clamp 15.

A device for filling long shells with powder material works as follows.

When the vibration exciter 6 is turned on, in the first half-cycle of oscillations the armature is attracted to the core, and in the second, when there is no current, the armature under the action of elastic forces of the springs returns to its previous position. Thus, the reciprocating movement of the active and reactive mass occurs with a frequency equal to the frequency of the supply current electromagnet.

The upper plate 7 and the supporting strut 9 mounted on it, attached to the vibration exciter 6, being the active mass, perform vertical reciprocating vibrations. These vibrations are transmitted from the support rack 9 to the bowl 12, due to the fact that the guide spline axis 16 of the bowl 12 is installed in the guide splined striker 10 of the support rack 9 freely, with the possibility of movement, the bowl 12 perceives the strikes of the striker 10 and vibrates in the vertical plane under their influence . The oscillations of the bowl 12 are transmitted to the long shells 3, mounted on the feeders 14 by means of pneumatic clamps 15, while the long shells 3 do not experience impacts.

The powder material from the hopper 18, dispenser 4, is fed by a screw into the nekpis 20, enters the powder distributor 23, which, rotating, directs the powder into the bowl 12. Under the influence of the shock pulse of the bowl 12 about the strips 10, the powder material moves to the feeders 14 (Fig. 8 ), while filling the long shells 3. Filling the long shells 3, the powder material blocks its exit from the feeder 14, thereby guaranteeing a fixed technological parameter - the height of the column of powder in the long shells 3.

In the process of compaction of the powder material, the height of its column decreases, and the incoming powder material from the feeder 14 fills the resulting space between the surface of the powder material in the long shells 3 and the lower end of the feeder 14 (Fig. 8).

This design of the device for filling long shells with powder material can improve the quality level of long shells, in terms of uniformity and increase the density (shaking) by 5% along the length of the product, which is confirmed by the test results of the prototype of the device.
