Abstract

The present invention relates to a granule or fine powder filling apparatus. In general, fine powders of a size of several tens of micrometers or less are adhered to each other due to electrostatic attractive force, resulting in agglomeration of the powders, It is extremely difficult to fill the powder uniformly. For example, in the case of universal filling apparatuses, the discharge port of the filling hopper and the inlet of the quantitative container are filled with each other while being filled, dust is generated through the space thus separated, After the granules and fine powder were stored in the container of the filling device, the operation was started. In this process, too much dust was generated, and there was a difficulty in metering the same weight depending on the physical properties of the powder.
Therefore, in the present invention, the fluidity problem caused by the aggregate phenomenon occurring in the natural discharge of the fine powder is configured to be sucked and discharged using the negative pressure of the venturi tube. In order to solve the problem of dust generated during filling, the discharge port of the filling hopper and the inlet of the constant- In addition, granules or fine powders, which are raw materials, must be stored in the container for filling. In addition, a large amount of dust generated in the process is formed by connecting the outlet of the raw material container and the inlet of the powder container After that, the powder container was saved through 180 ° rotation and reverse rotation to solve the dust problem. The problem of quantitative metering of the same weight according to the physical properties of the powder was found to be caused by a triangular column having a hypotenuse and a conical rotary shaft And the specific gravity of the granules or the fine powder is uniformly accommodated by the granules. The dust problem was solved by the machine, so that the worker could work safely without any loss of raw material. The problem of unbalanced weighing according to the physical properties of the powder was solved, so that the same weight was always measured.

Description

[0002] Fixed weight filling equipment [0003]

The present invention relates to a filling device combined with a granule or fine powder feeder, and more particularly, to a same weight feeder filling device which can uniformly and continuously fill granules or fine powders at the same weight without dust at all times

In general, fine powders having a size of several tens of micrometers or less are adhered to each other due to electrostatic attraction, so that aggregation occurs. As a result, the fluidity of the agglomerated powders is extremely deteriorated. Thus, it is extremely difficult to fill the powder uniformly by a conventional method. In the case of powder, natural scattering occurs due to the size of fine particles when falling, which is harmful to the health of workers due to a large amount of dust. Therefore, it is preferable that the hopper discharging port of the filling device and the charging port of the quantitative container are sealed and filled without dust in order to fill the quantitative container with no dust. However, in order for the powder to be accommodated in the metering vessel, air of the volume of the powder to be received must be discharged out of the metering vessel to achieve powder filling. Therefore, unless the discharge port of the hopper and the quantitative container are sealed, there is no discharge device for discharging the air in the fixed quantity container.

However, the conventional method of filling granules or fine powders, the auger method using a screw and the powder receiving hole in the rotating plate, and the vibration method of supplying the powder received by using the vibrator and the hammer blow, It is necessary to form a filter in the case of fine powder because the fine particles can easily penetrate into the filter tissue and the function of the simple filter is lost and the use is impossible. And the powder is discharged together with the air in the quantitative container through the separated space to generate a large amount of dust. Also, there is a problem in the loss of raw material due to dust and precise quantitative measurement.

In addition, in the case of the auger method, the powder stored through the funnel-shaped hopper in which the powder is stored and the auger (screw) provided in the center of the hopper are pressed and filled through the hopper discharge port, Dust discharge causes a large amount of dust, and metering by auger rotation is difficult to accurately measure. Also, in this method, the powder is transferred to the funnel-shaped hopper located at the upper layer portion through the transfer screw, and the filling operation is started after the storing operation. In order to start the filling operation, a separate powder container communicating with the transfer screw is provided. The powder is poured and stored and then stored in the funnel-shaped hopper by the conveying screw. In this process, a large amount of dust is generated, and the equipment is complicated by additional equipment such as a suction device and a feed screw for dust removal.

The vibration system using the vibrator and the hammer striker transmits vibration to the powder container in which the powder is stored to prevent the fine powder from stagnating or accumulating on the wall surface of the powder container, The fine powder discharged through the discharge port of the powder container has a limitation in uniform discharge due to the vibration caused by the impact, The powder contained in the powder receiving hole has a specific gravity difference depending on the degree of stickiness of the physical properties, which causes a problem in uniform weighing. Also, in the process of transferring granules or fine powder to the powder container located at the upper part of the upper part, the granule or powder is poured into the powder container using a device such as a lift, so that a large amount of dust is generated. And a suction device is additionally installed to remove dust as described above.

Conventional granules or fine powder filling and feeding methods are filled with granules or fine powders in a state where the hopper discharge port and the quantitative container input port are spaced apart, and there is a problem In the case of the auger method, there is a weight deviation due to the metering according to the number of revolutions of the screw. In the case of the vibration method, the powder contained in the powder receiving hole is metered by impact or vibration of the powder container. The density of the powder contained in the receiving hole is not uniform and there is a weight deviation due to the dust only by vibrations or blows from the outside.

In order to initiate the filling operation, the above methods require that the granules or the fine powder contained in the raw material container be transported to a powder vessel (vibration system) or a funnel-shaped hopper (auger system) located in the upper layer. The process of pouring granules or fine powders through. This causes a large amount of dust to be generated, resulting in loss of raw material. In addition, there is a problem that the equipment is complicated due to an additional suction device and a separate equipment for dust removal. In case of pesticide harmful to the human body, There is a problem with safety of workers. Therefore, the same weight supply device is aimed at improving the above problems.

According to the present invention, when a small amount of air pressure is injected into the air supply pipe 610 of the venturi pipe 600, which is a powder vacuum transfer component shown in FIG. 1, from the air supply device such as the compressor 605, Pressure vacuum negative pressure is generated by a small amount of air, whereby a small amount of air is sucked into the suction pipe 609 through the air inflow hole 321 provided in the suction space. At this time, a suction motor The vacuum negative pressure of the low pressure is converted into the vacuum compliance of the high pressure due to the phenomenon of the whirling phenomenon. Therefore, the air used for the powder conveyance is the main cause of the dust, and even when a small amount of air is injected into the air supply pipe 610, A negative pressure of a high pressure is generated in the suction pipe 609 so that a large amount of powder can be transferred to the vent pipe 609.
