BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid material lifting device and a transfer method, and more particularly, to a fluid material lifting device and a transfer method which are capable of rotating a rotating tube surrounding a fixed spiral guide member, And more particularly, to a fluid material vertical up-feed device and a transfer method that smoothly carry out vertical up-feed.

In general, a vertical lift transfer device is used to transfer a flowable material such as grain to a plant or other process.

Such a vertical lifting and conveying apparatus for a fluid material includes a pneumatic conveying type, a screw conveyor type, and a bucket-elevator type conveying apparatus, but there is a disadvantage that improvement is required in each method.

That is, the pneumatic conveying type conveying apparatus has a disadvantage in that the operation cost is relatively increased due to relatively maintenance and management by using a blower or a compressor, and the abrasion damage of the fluid material during transportation of the fluid material is severe.

In addition, the screw conveyor type transfer device also has a disadvantage that the friction between the fluid material particles increases due to the relatively high operation speed, and the wear of the fluid material during the transfer of the fluid material is severely damaged.

In addition, the bucket-elevator type conveying apparatus has a disadvantage of high facility cost and a high maintenance cost burden due to major damage such as a belt, a chain, and a bucket.

Also, the prior art has a disadvantage in that dust is generated during transfer of a fluid material. 6, the flowable material M is conveyed by the conveying screw rotating in the conveying pipe 2 during the vertical upward conveying of the fluid material using the conveying screw 1 of the prior art, And is vertically lifted up.

At this time, an empty space part 4 in which the fluid material M is not filled is present in the transfer pipe 2, and the flow of the fluid material vertically raised and raised by the space part occurs, As well as the downward flow of the flowable material which is vertically raised and the transport efficiency is lowered.

Also, in the bucket-elevator type, a large amount of empty space in which the fluid material is not filled in the case during the vertical upward movement of the fluid material by the bucket operating in the elevator type causes not only a large amount of dust such as dust in the case, In case of bucket-elevator type, it has a complicated mechanical structure inside the case, resulting in sparks due to machine breakage or impact, overheating of bearings or pulleys, or friction between bucket and flowable material accumulated on the bottom of bucket-elevator case There is a problem that explosion or detonation may occur due to ignition of dust inside the case by heating.

In addition, the prior art has a serious disadvantage of damaging the flowable material when it is used in the field of grocery handling. In particular, in the case of vertically lifting the fragile flowable material such as freeze-dried coffee granules, Development of vertically rising conveying device and conveying method of fluid material that enables smooth conveyance without generating dust during conveying of fluid material while preventing damage to the fluid material due to serious damage of granular particles in spite of frequent collision and smooth handling This is an urgent situation.

The discharge chute 401 may be provided with a connection pipe for supplying the finally discharged fluid material to the next process or plant.

A method of vertically moving the fluid material using the fluid material vertical up-feed device of the present invention constructed as described above will be described as follows.

When the fluid material is supplied to the material feed hopper 102 for vertical up-feed of the fluid material, the fluid material is rotatably installed so as to have a predetermined working gap G between the spiral guide member 20 and the inner surface of the rotary tube 30 The flowable material is introduced through the inlet 301 formed in the rotary pipe 30 of the flowable material vertical upturn conveying device including the helical guide member 20 which is fixedly installed and fixed by the rotary pipe 30.

That is, the rotary pipe 30 is supported by the bearing means 307 so as to be rotatable while maintaining a constant height at the bottom surface of the material supply hopper 102.

Therefore, when the rotary pipe 30 is rotated by the driving means in a state where the fluid material is supplied to the material supply hopper 102, the inflow guide member 30, which protrudes outward from the lower end of the rotary pipe 30 in the rotating direction of the rotary pipe 30, The flowable material supplied to the material supply hopper 102 by the flow path 308 flows into the inside of the rotary pipe 30 through the opening 309 at the lower end of the rotary pipe 30 on the inner surface of the inflow guide member 308.

At this time, when the rotating tube 30 continues to rotate, the fluid material is pressed toward the inner wall of the rotating tube 30 by rotation of the rotating tube 30, and is filled in the inner space of the rotating tube 30, The step of vertically ascending is performed by the shape of the helical guide member 20 installed inside.

That is, when the fluid material continues to flow into the rotary tube 30 as the rotary tube 30 continues to rotate, the inflow pressure of the fluid material acts on the inner space of the rotary tube 30.

At this time, the remaining space excluding the helical guide member 20 occupying the volume of the inner space of the rotary pipe 30 is filled with the fluid material, and the inflow pressure of the fluid material, The flowable material is transported upwardly from the bottom of the rotary tube 30 along the helical blade 202 of the helical guide member 20. [

Accordingly, since the fluid material is transferred to the inside of the rotary tube 30 without a space in the vertical up-transfer process of the fluid material, dust or dust can be prevented from being generated during the transfer of the fluid material.

The flow guide member 308 formed at the lower end of the rotary pipe 30 during the rotation process of the rotary pipe 30 guides the flowable material supplied to the material supply hopper 102 into the rotary pipe 30, The material is not pushed up in the vertical direction but the fluid material is spirally pushed up about the shaft 201 of the spiral guide member 20 provided inside the rotary pipe 30 as a central axis, The pressure acting vertically between the helical blade 202 and the fluid material is minimized, thereby enabling smooth vertical lift transport while minimizing damage to the fluid material particles.

The cylindrical volume inside the rotary tube 30 occupied by the helical guide member 20 and the working gap G between the inner peripheral surface of the rotary tube 30 are formed to be smaller than the average particle diameter of the fluid material, It is possible to prevent the flowability of the flowable material from deteriorating by preventing the flowable material from flowing backward through the working gap G in the process of vertically moving upward the material from the lower part to the upper part of the rotary pipe 30. [

The fluid material supplied to the material supply hopper 102 is supplied into the rotary pipe 30 through the inlet 301 of the rotary pipe 30 by the rotation of the rotary pipe 30, The inflow speed of the inflowing fluid material through the inflow port 301 formed in the inflow port 30 is adjustable according to the shape of the inflow guide member 308 formed in the rotatable pipe 30. [

That is, the inflow guide member 308 formed at the lower end of the rotary tube 30 is protruded outward from the peripheral wall of the rotary tube 30, so that the inflow guide member 308, which is formed by the inflow guide member 308 and the outer peripheral surface of the rotary tube 30, By varying the shape of the member 308, such as the angle of deployment of the member 308, the height, length, and angle of the inlet guide member 308, the curvature leading from the inside to the outside, the curvature leading from the top to the bottom, It is possible to control the inflow speed of the material by not only changing the shape of the inflow guide member 308 but also changing the material such as forming the inflow guide member 308 with a material having elasticity.

The inflow speed of the fluid material can be controlled by adjusting the rotation speed of the rotary tube 30. The rotation speed of the rotary tube 30 and the inflow speed of the fluid material are directly proportional to each other.

The flow rate of the flowable material is preferably adjusted appropriately according to the characteristics of the fluid material to be handled.
