Such a vertical screw method has no big problem in conveying the conveying material generally formed in the form of grains or grains in a dry state.

However, in the case of a dough or cake form containing moisture in the conveying material, there is a problem in that the conveying material does not smoothly convey and convey the conveying material while the conveying material increases the friction coefficient with the screw when conveying by the vertical screw.

In order to improve such a problem, the screw has to be installed in an inclined structure (about 45 °) rather than vertically to transfer a transfer material such as a dough or cake form containing moisture.

As described above, the inclined installation structure of the conveying screw has a problem in that the installation work is difficult and inconvenient as the inclined installation of the conveying pipe is accompanied with the disadvantage that the installation space for screw conveyance is considerably wider.

That is, in the related art, the transfer material such as dough or cake form containing moisture is used to transfer the transfer material smoothly from the bottom to the top only with the vertically installed transfer screw, despite the advantages of the vertical feed mechanism. It has become impossible structurally.

Accordingly, the present invention has been invented to solve the above-mentioned problems of the prior art, and in various forms, for example, moisture, by allowing the conveying material to be vertically conveyed by the vacuum suction force together with the conveying force of the vertically installed conveying screw. The purpose is to maximize the use efficiency by providing the maximum transfer effect to the minimum installation area by enabling the vertical and smooth transfer of the transfer material, such as dough, cake form.

The transfer material supplied to the temporary storage tank or the mixing tank in the lower position is transported to the upper vertical through the feed pipe with a vertical screw driven by a drive motor,

The temporary storage tank or the mixing tank is provided with an air suction valve for introducing external air by opening and closing operation,

The suction brower is installed at the upper outlet of the transfer pipe by a suction reservoir connected to a suction reservoir for discharging the transfer material to the lower reservoir by opening and closing the lower gate, and a suction tube having a check valve at one side of the suction reservoir. It is sufficiently achieved by feeding and feeding the conveying material by the vacuum suction input by the suction operation of the screw and the rotational conveying force of the screw.

The suction reservoir of the present invention is characterized in that it is connected to the suction pipe to form a zigzag-type discharge path to the upper and lower in order to suction and discharge only the internal air on one side of the inside.

The suction pipe of the present invention is characterized by further comprising a suction auxiliary tank for preventing the dry contents contained in the transport material is introduced into the suction blower and damaged.

The present invention is to vertically transfer the feed material in the form of a dough, cake type, as well as the general transport material, moisture, by the vacuum suction force generated by the suction operation of the suction brower with the screw feed force inside the transfer pipe. Since the transfer material is smoothly transported vertically to provide the maximum effect on the minimum installation area has the effect of maximizing its use efficiency.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

The vertical screw feeder of the present invention is characterized in that it feeds and feeds the feed material in the form of cake or dough to the vertical top, including a general feed material or a large amount of water.

That is, the apparatus of the present invention, as shown in Figures 1 and 2, the vertical screw (3) for driving the conveying material supplied to the temporary storage tank or mixing tank (2) of the lower position by the drive motor (M) It is provided to transfer the supply to the upper reservoir (7) through the built-in transport pipe (5).

At this time, the temporary storage tank or the mixing tank (2) is provided with an air intake valve 10 for introducing external air by the opening and closing operation,

The upper outlet 6 of the transfer pipe 5 has a suction reservoir 20 for discharging the transfer material to the lower reservoir 7 by the opening and closing operation of the lower gate 22, and a check valve opening and closing at one side of the suction reservoir. A suction brower 30 connected to the suction pipe 31 having the suction pipe 32 is installed to feed and feed the material with the vacuum suction input by the suction operation of the suction brower and the feed force by the rotational movement of the screw.

It is controlled to open only during the suction operation of the suction blower 30 of the air suction valve 10.

In addition, the suction reservoir 20 is connected to the suction pipe 31 by forming a zigzag discharge path 25 up and down by a plurality of partitions 26 and 27 to suction and discharge only internal air on one side of the suction reservoir 20. Configure to

In addition, on the suction pipe 31 is configured to provide a suction auxiliary tank 35 to prevent the dry contents contained in the transport material in the middle flows into the suction bro.

As an unexplained symbol, 4 represents a feed hopper.

Next will be described the operation and action of the present invention configured as described above.

The present invention is to provide a conveying material in the form of cake or dough, including a general conveying material or a large amount of water to the vertical screw to add a vacuum suction force to the conveying force to smoothly supply.

In more detail, the transfer material in the form of cake or dough containing a large amount of water in the temporary storage tank or the mixing tank (2) in the lower position is supplied through the hopper (4).

In this state, the driving motor M rotates and drives the screw 3 inside the transfer pipe 5 to transfer and supply the transfer material in the temporary storage tank or the mixing tank 2 to the upper portion.

Along with this, the suction brower 30 is operated to suction.

That is, the suction brower 30 has the check valve 32 of the suction pipe 31 opened to suck out and discharge the air in the suction reservoir 20 to generate a vacuum suction force in the suction reservoir 20.

At this time, the air suction valve 10 of the temporary storage tank or the mixing tank 2 is opened at the same time.

When the vacuum suction force is generated in the suction reservoir 20 by the suction brower 30 as described above, the vacuum suction force is also generated in the transfer pipe 5 connected to the suction reservoir 20.

In addition, the temporary reservoir or the mixing tank 2 serves to push external air through the air suction valve 10 to push the transport material from the lower side.

Therefore, the transport material in the temporary storage tank or the mixing tank 2 is smoothly transported and supplied to the vertical material by the vacuum suction force with the conveying force by the screw (3) inside the vertical conveying pipe (5) will be.

Moreover, even if the conveying material contains a large amount of water, the cake is smoothly fed vertically even in the form of a cake or dough.

In this way, the transport material is transferred to the suction reservoir 20.

At this time, the lower portion of the suction reservoir 20 is in a state in which the gate 22 is closed.

In addition, the suction broth 30 connected to the suction reservoir 20 and the suction pipe 31 continuously performs the suction operation in the process of transporting and supplying the transport material to the suction reservoir 20 as described above. Only air is sucked from the reservoir 20.

The suction path of the internal transport material is formed by forming a zigzag discharge path 25 up and down by a plurality of partitions 26 and 27 on one side of the suction reservoir 20 and connecting the suction pipe 31 to the suction pipe 31. It will block the emissions.

And some of the dry contents contained in the transport material in the suction reservoir 20 may be sucked out by the suction force of the suction brower 30, the transport material (for example, dry dust, etc.) is a suction pipe (31). While being discharged through) is filtered by the suction auxiliary tank 35 in the middle of the suction pipe 31 to prevent the transport material is discharged to the suction brower (30).

That is, the problem of damaging the suction broacher 30 by the conveying material is prevented.

As described above, when the transfer and supply of the transport material to the suction reservoir 20 is completed, the driving of the screw by the driving motor M is stopped, and the suction operation by the suction brower 30 is also stopped.

In addition, the air suction valve 10 formed in the temporary reservoir or the mixing tank 2 is blocked again.

In such a state, if necessary, the gate 22 of the lower portion of the suction reservoir 20 may be opened to drop and supply the transport material to the lower reservoir 7.

As such, when all of the transport material in the suction reservoir 20 is supplied, the gate 22 is closed again in the original position.

On the other hand, the present invention can also be used as a structure in which the suction auxiliary tank 35 is removed on the suction pipe 31 as shown in FIG.
