Description

Rotary shell reactor using magnetic drive {ROTARY SHELL REACTOR WITH MAGNETIC DRIVE}

The present invention relates to a rotary shell reactor using a magnetic drive, and particularly to a rotary shell reactor in which a tubular rotary shell rotated by a magnetic drive is incorporated inside a fixed tubular reactor.

In general, a rotary kiln reactor refers to a long tube used as a continuous plug flow reactor. For example, as schematically showing the structure of a typical rotary shell reactor in Figure 1, the tube-shaped rotary shell reactor (1) is , A driving device (2) is connected to one side to be rotatable, and after the raw material is input into the raw material inlet (3) formed on one side of the rotary shell reactor (1), the heater (5) moves toward the material outlet (4). ), the raw materials are dried, fired, or mixed while being heated.

As described in Republic of Korea Patent Registration No. 10-1714840 (Patent Document 1), it is used for drying, calcining or reducing raw materials such as ore, or as described in Korea Patent Registration No. 10-1807077 (Patent Document 2). It is not only applied to various industrial fields such as drying, torrefaction, and carbonization of raw materials such as mass, waste, sludge, and food waste, but also by installing partitions such as baffles inside the reactor. Further improved rotary shell reactors are being developed to suit each industrial field, including improving performance.

However, as shown in FIG. 1, the rotating rotary kiln reactor 1 has a seal structure with the fixed flange portion (for example, the portion indicated by the oval dotted line in FIG. 1) supporting the rotary kiln reactor 1 due to its operating characteristics. Because it is limited, there is an inevitable risk of leakage, and as a result, it poses a safety risk when using hazardous gases or when using it in high vacuum or pressurized process conditions.

Moreover, welding work is required to install a baffle plate inside a general rotary kiln reactor (1), and if the inner diameter of the rotary kiln reactor (1) is small, the work movement of the welding device may be obstructed, so the baffle plate is installed. Not only is it difficult to do this, but there are limits to manufacturing a small rotary kiln reactor (1) because the minimum inner diameter size of the reactor is determined for welding work.

More specifically, the fixed tubular reactor 10 is a cylindrical tube-shaped fixture with a predetermined length, on one side of which is connected an inlet cover 11 through which raw materials are introduced, and on the other side is an outlet cover through which processed materials are discharged ( 12) is connected, and a heating means 13 for heating the raw materials is provided on the outer surface of the fixed tubular reactor 10.

The heating means 13 may be an electric heater using electrical resistance or a method of circulating heated gas or liquid, and there is no limitation in the method or type.

The raw material supply unit 20 is provided to inject raw materials into the inlet cover 11 of the fixed tubular reactor 10, and various known mechanical devices can be applied to its structure.

As a preferred embodiment of the raw material supply unit 20, as shown in the drawing, a hopper 21 into which raw materials are input, and a supply feeder 22 connected to the lower part of the hopper 21 to transfer the raw materials to the inlet cover. ) may be included, and in this case, the supply feeder 22 may be provided by a screw transfer method.

In addition, the driving source for driving the supply feeder 22 may be a magnetic drive 23 that transmits power through the attractive force of a magnet.

Magnetic Drive (MD) transmits power by using the attractive force of magnets rather than by belts or gears. Magnets are installed inside and outside the metallic housing, respectively, and the external Using a magnet as a power source, the internal magnet can be rotated by magnetic force (attractive force). Since this structure is a known device, detailed description thereof will be omitted.

The tubular rotary shell 100 is disposed inside the fixed tubular reactor 10 and is rotatable by the above-described driving means 30. Specific embodiments thereof will be described with reference to FIGS. 3 and 4, which will be described later. I decided to do it.

The driving means 30 is connected to the inlet side of the tubular rotary shell 100 and is provided to rotate the tubular rotary shell 100, and the motor 31 and the rotational force of the motor 31 are combined with the attractive force of the magnet. It may include a rotary magnetic drive 32 that transmits power to.

As described above, the rotary magnetic drive 32 may be a known device that installs magnets inside and outside, respectively, to transmit power through magnetic force (attractive force).

When the magnetic drive structure is applied to the rotary shell reactor of the present invention, the outer magnet is connected to the rotation axis of the motor 31 and the inner magnet is connected to the tubular rotary shell 100. In this case, the inner magnet of the rotary magnetic drive 23 The space where this is located and the space where the outer magnet is located are not physically connected and are blocked.

Therefore, the internal space of the fixed tubular reactor 10 is in an airtight state blocked from the outside air by the inlet cover 11, the outlet cover 12, and the rotary magnetic drive 23 connected to the inlet cover 11. Because it can be maintained, it is possible to process toxic raw materials or explosive materials, and furthermore, it can meet the conditions of use in high vacuum or pressurized environments.

The collection unit 40 is connected to the outlet of the fixed tubular reactor 10 and is a device for collecting processed materials.

Meanwhile, as referring to FIGS. 2 and 3, the tubular rotary shell 100 includes a tubular rotating body 110, an inlet drum 120, and an outlet drum 140 connected to the driven shaft 130. can do.

More specifically, the tubular rotating body 110 has a cylindrical tube shape with an inlet 111 and an outlet 112 formed at both ends, respectively.

The inlet side drum 120 is fixed to the inlet 111 of the tubular rotating body 110, and the tubular rotating body 110 is connected to the rotary magnetic drive 23 via the inlet drum 120 to form a fixed tubular reactor. (10) It is provided so that it can be rotated internally.

The inlet drum 120 is connected to a rotary magnetic drive 32 and extends from the center of the disc-shaped driving plate 121 to rotate, toward the outlet 112 of the tubular rotating body 110. It can be supported by a drive shaft 122 and a plurality of inlet side supports 123 formed radially from the end of the drive shaft 122.

At this time, the inlet drum 120 may be fixed in the form of being inserted into the inlet 111 of the tubular rotating body 110, but such assembly structure is not limited to the structure illustrated in the drawings and can be modified into various assembly structures. You can.

A driven shaft 131 connected to the outlet drum 140, which will be described later, is disposed at the outlet 112 of the tubular rotating body 110, and at this time, the driven shaft 131 is connected to the outlet 112 of the tubular rotating body 110. It is located at the center of the annular connecting ring 130 fixed to, and a plurality of outlet side supports 132 formed radially are provided between the inner surface of the connecting ring 130 and the outer surface of the driven shaft 131.

In addition, the outlet drum 140 is in the form of a cylindrical tube connected to the driven shaft 131 and rotatable, and the material processed in the fixed tubular reactor 10 is stored on its outer peripheral surface by the collection unit 40. A plurality of discharge holes 141 are formed for discharge to .

At this time, the outlet drum 140 further includes a disc-shaped blocking plate 142 with a shaft hole 143 formed at the center so that the driven shaft 131 penetrates and is fixed, and the outlet drum in the form of a cylindrical tube. (140) is formed in a form extending from the edge of the blocking plate 142 toward the outlet 112 of the tubular rotating body 110.

Additionally, the end of the driven shaft 131 that penetrates the blocking plate 142 may be coupled to a bearing (not indicated) provided in the outlet cover 12.

The rotary shell reactor of the present invention configured as described above operates as follows.

When the raw material is introduced into the inner space of the inlet cover 11 through the supply means 30, the raw material flows between the driving plate 121 and the inlet 111 of the tubular rotating body 110, as indicated by the arrow in FIG. 4. It is internalized.

At this time, as the tubular rotary shell 100 including the tubular rotary body 110 rotates, the raw materials are processed such as drying, firing, or mixing while being transferred to the outlet side of the fixed tubular reactor 10, and then the tubular rotary body ( The material that reaches the outlet cover 12 through the outlet of 110 is sequentially discharged through the discharge hole 141 of the rotating outlet drum 140 and collected into the collection unit 40.

Here, in order to facilitate the transfer of the raw material introduced between the driving plate 121 and the inlet 111 of the tubular rotating body 110, a plurality of inlet side supports 123 arranged radially as shown in FIG. 3 are provided on the tubular rotating body ( 110) may be formed to have a predetermined length in the longitudinal direction and be twisted at a predetermined angle, such as a pinwheel or screw.

In this case, since the raw materials in the inlet drum 120 are pushed by the inlet support 123 and move inside the tubular rotating body 110, even if the fixed tubular reactor 10 is placed horizontally, stagnation phenomenon occurs during transfer of the raw materials. It can be prevented.

Figure 5 shows the modified internal structure of the tubular rotating body in the rotary shell reactor of the present invention. As described above, it is used to prevent stagnation when transferring raw materials within the fixed tubular reactor 10 and improve the mixing of raw materials. A modified example for this is shown.

Referring to FIG. 5 , a plurality of protrusions 113 may be formed along the longitudinal direction on the inner peripheral surface of the tubular rotating body 110, and each protrusion 113 may be arranged in a spiral shape.

In this way, when the spiral protrusion 113 is formed over the entire section of the tubular rotating body 110, when the tubular rotating body 110 rotates, the raw material is pushed in the transport direction by the spiral protruding body 113 and falls at the same time. As fluidity increases, the mixability of raw materials can be improved.

As such, the above description has been made according to limited embodiments showing the technical idea of the present invention, but the present invention is not limited to specific embodiments, shapes, and values, and some of the components of the embodiments may be changed, mixed, etc. Various modifications and variations can be made by those skilled in the art without departing from the gist of the invention, and such modifications and variations should not be individually understood from the technical idea or outlook of the present invention.
