As shown in FIGS. 2 to 6, the coating apparatus for continuous flame retardant isosbee according to a preferred embodiment of the present invention has a vertical cylindrical shape, and a raw material and a binder are supplied and mixed therein, A body part 110 provided inside the body part 110 to divide the internal space of the body part 110 at predetermined intervals to provide a plurality of mixing spaces, A rotation unit 120 for mixing the raw material and the binder so that the binder is coated on the raw material while being turned from the upper mixing space to the lower mixing space by rotation by the power provided from the outside, A driving unit 130 for rotating the rotating unit 120 by providing power to the rotating unit 120 disposed inside the body 110 and a driving unit 130 for rotating the rotating unit 120, And an air supply unit 140 for supplying raw materials coated with the binder in the plurality of mixing spaces partitioned by the rotating unit 120 by supplying the air from the upper mixing space to the lower mixing space.

The body 110 has a vertical cylindrical shape and is a housing means for providing a space in which the raw material and the binder are supplied and mixed therein so that the binder is coated on the raw material and then discharged to the outside. A tank 111 having a cylindrical shape and having a predetermined hollow therein and a hopper provided at the upper end of the tank 111 to continuously supply a predetermined amount of raw material such as beads and the like from the raw material supply means into the tank 111 A binder injection means 113 such as a spray nozzle for supplying a predetermined amount of a binder such as a flame retardant and the like from the binder supply means to the inside of the tank 111 at the upper end of one side of the tank 111, A raw material discharge port 114 formed at the lower end of the tank 111 for discharging the raw material coated with the binder from the inside of the tank 111 continuously to the outside, It includes.

The driving unit 130 is a driving unit that is provided outside the body 110 and provides power to the rotating unit 120 formed inside the body 110 to rotate the rotating unit 120. The driving unit 130 includes a tank 111, A drive pulley 133 connected to the drive shaft 132 of the drive motor 131 for generating a drive force and a drive pulley 133 connected to the drive pulley 133 via a belt 134 And is connected to the rotation pulley 135 in a state of being positioned in the longitudinal direction of the tank 111 to the inner hollow portion of the tank 111 to generate a rotating force, A rotating shaft 136 rotating the bottom rotating plate 122, and the like.

The driving unit 130 may be configured such that the driving shaft 132 of the direct driving motor 131 is connected to the rotating shaft 136 through a joint instead of constituting the driving pulley 133 or the rotating pulley 135, .

The rotation part 120 is formed inside the body part 110 to divide the internal space of the body part 110 at regular intervals to provide a plurality of mixing spaces, And the bottom surface of the tank 111 is connected to the lower mixing space so that the raw material and the binder are mixed so that the binder is coated on the raw material. A plurality of upper rotating plates 121 disposed on the rotating shaft 136 of the driving unit 130 to provide a plurality of mixing spaces and a binder disposed on the bottom surface of the rotating shaft 136 of the driving unit 130, And a bottom rotating plate 122 for allowing the coated raw material to be discharged to the raw material outlet 114 of the body portion 110.

The upper rotating plate 121 is disposed in an upper space inside the tank 111 excluding the bottom surface in a state of passing through the rotating shaft 136 to provide a plurality of mixing spaces. Shaped rotary panel 121a having a diameter smaller than the inner diameter of the tank 111 and having a width corresponding to the gap between the outer circumferential surface of the rotary panel 121a and the inner diameter of the tank 111, A pair of vertical plates 121b vertically protruding from the outer circumferential surface of the rotary plate 121a at an interval of 180 degrees, a shape facing each other on the upper surface of the rotary panel 121a divided by quadrants, And a plurality of blades 121c protruding at a predetermined height toward the center of the vertical plate 121b to provide a predetermined centrifugal force to the raw material and the binder positioned in the mixing space together with the vertical plate 121b to cover the raw material with the binder,Are formed to penetrate through the corresponding portions of the front panel 121a while having mutually opposing shapes and structures so that the blades 121b and the blades 121c are relatively in contact with the raw materials, And a plurality of moving holes 121d for moving the raw material coated with the binder having a large specific gravity to the lower mixing space.

That is, according to the upper rotation plate 121, when the rotation plate 121a is rotated by the driving unit 130 while a predetermined amount of the raw material and the binder are supplied to the mixing space, the vertical plate 121b and the blade 121c, The raw materials are mixed and collided with each other while forming a turbulent flow. As a result, the binder is mixed with the raw materials so that the binder is covered with the raw material. At this time, the raw material without the binder is relatively small in weight relative to the raw material coated with the binder. The raw material without the binder having a small specific gravity is raised upward by the turbulent flow of the centrifugal force of the vertical plate 121b and the blade 121c to increase the possibility of contact with the binder Accordingly, the coating efficiency of the raw material not coated with the binder becomes high. The raw material coated with the binder having a large specific gravity is lowered to the lower side of the mixing space and is moved between the outer peripheral surface of the rotary panel 121a and the inner peripheral surface of the tank 111 formed in the rotary panel 121a, To the lower mixing space. On the other hand, even if the raw material having a low specific gravity in a state in which the binder is not coated is moved from the upper mixing space to the lower mixing space due to the lowering of the raw material coated with the binder, the centrifugal force of the vertical plate 121b and the blade 121c The turbulence causes the turbulent flow to rise up to the upper mixing space through the gap formed between the outer circumferential surface of the rotary panel 121a and the inner circumferential surface of the tank 111 to further increase the possibility of contact with the binder, The binder can be coated upon mixing and impingement with the material, resulting in an increase in coating efficiency of the raw material.

The bottom swing plate 122 is positioned on the bottom surface of the rotary shaft 136 of the driving unit 130 so that the raw material coated with the binder sequentially moved in the mixing space is mixed with the raw material of the body 110 A rotary plate 122a having a circular shape having a diameter corresponding to the inner diameter of the tank 111 and a rotary panel 122a partitioned into quadrants, And a predetermined centrifugal force is applied to the binder and the raw material placed in the mixing space so that the binder is coated on the raw material and at the same time, A plurality of upper blades 122b for allowing the coated raw material to be discharged to the outside toward the raw material discharge port 114 and a lower surface of the rotary panel 122a facing each other from the central portion toward the outer peripheral surface, So that the raw material located on the bottom surface of the tank 111 is discharged to the outside of the raw material discharge port 114 even if the raw material is infiltrated into the gap between the outer peripheral surface of the rotary panel 122a and the inner peripheral surface of the tank 111 And a pair of lower blades 122c and the like.

That is, according to the bottom swing plate 122, when the plurality of mixing spaces are sequentially moved by the upper swing plate 121 and the binder-coated raw material is moved to the last lower mixing space by the driving unit 130 When the rotary panel 122a is rotated, the raw materials are mixed and collided with each other by the upper blade 122b and the lower blade 122c so that the binder is finally coated on the raw material, and the centrifugal force is applied to the tank 111, It is possible to discharge a predetermined amount to the outside when reaching the raw material discharge port 114 during the rotation movement.

Meanwhile, in the case of the bottom swing plate 122, the rotary plate 122a has a circular plate shape and the blades are formed on the upper and lower sides of the rotary plate 122a. However, in the state where the rotary plate 122a has an upside- It is possible to completely cover the bottom surface of the tank 111 so that the raw material can not be infiltrated into the bottom surface of the tank 111. Thus, the configuration of the lower blade 122c is omitted and only the upper blade 122b .

The air supplying unit 140 is provided on the side of the body 110 and supplies air to the inside of the body 110 to supply the raw material coated with the binder in a plurality of mixing spaces defined by the rotating unit 120, The air supply means is an air supply means which is arranged radially on the inner circumferential surface of the tank 111 in a state in which the air supply means is located at a lower side of the raw material supply port 112 of the tank 111, And a diffuser 142 for uniformly injecting the air supplied from the air supply pipe (not shown) into the inner space of the tank 111 and the like.

That is, according to the air supplying unit 140, when the raw material and the binder are mixed and coated by the rotating unit 120 in the plurality of mixing spaces, the raw material has a very small specific gravity, The raw material is easily moved upward to the upper part of the mixing space and is prevented from moving to the lower mixing space. When the binder is coated and the raw materials having a relatively larger specific gravity than the raw materials are lowered to the lower part of the mixing space So that the coating efficiency of the raw material can be improved.

Hereinafter, the operation of the continuous flame retardant epoxy resin coating apparatus according to the preferred embodiment of the present invention will be described.

First, a raw material such as beads is supplied from a raw material supply means to a mixing space at the uppermost end of a mixing space of a body 111 (110) partitioned by a rotation unit 120 through a raw material supply port 112 do.

The rotary plates 121 and 122 of the rotary unit 120 are rotated by the driving unit 130 and a binder such as a flame retardant or the like is supplied from the binder supply unit to the mixing space at the uppermost end of the tank 111, The air is uniformly injected into the mixed space at the uppermost and the most side by the air supply unit 140 at this time.

When the raw material supplied to the uppermost mixing chamber is rotated by the turbulence formed by the vertical plate 121b and the blade 121c when the rotary plate 121a of the upper rotary plate 121 rotates, The binder is mixed and collided with the binder while being mixed and collided, and the binder is covered with the raw material. At this time, in the case of the raw material not coated with the binder, the binder has a relatively small specific gravity as compared with the raw material coated with the binder, The raw material coated with the binder having a large specific gravity is lowered to the lower side of the mixing space, The air supplied from the upper side causes the moving hole 121d formed in the rotary panel 121a and the outer peripheral surface of the rotary panel 121a and the outer peripheral surface of the tank 1 11 to the lower mixing space through the spaced gaps between the inner peripheral surfaces.

Here, it is preferable that the rotation unit 120 has a rotation speed of about 1500 rpm to 2000 rpm. At this time, if the rotation panel 121a has a rotation speed of less than 1500 rpm, the rotation speed is too slow, When the rotating panel 121a has a rotational speed exceeding 2000 rpm, there is a problem that the stirring efficiency is lowered due to the load of the raw material supplied at a weight of 5 to 5 tons, There is a problem in that the coating operation is not performed substantially.

Thus, it is possible to have a production amount such that the raw material having a weight of 3 to 5 tons per hour is coated on the binder through the rotation unit 120 having a rotation speed of about 1500 rpm to 2000 rpm, The coating efficiency can be increased and the production efficiency can be improved.

When all of the raw materials supplied to the uppermost-end mixed space are moved to the mixed space at the lower-end thereof, raw materials such as beads are continuously supplied from the raw material supplying means to the raw material supply port 112 And the raw materials moved to the mixing space at the lower end thereof are supplied to the rotary panel 121a by the turbulence in accordance with the centrifugal force of the vertical plate 121b and the blade 121c formed in the rotary panel 121a located in the mixing space, 121a and the inner circumferential surface of the tank 111, and is then moved upward again to the mixed space at the upper side of the upper side to be brought into contact with the binder or mixed with the binder-coated raw materials, Is moved to the mixed space at the lower end thereof, and the above process is repeated continuously.

Thereafter, the rotating panel 122a of the rotating unit 120 is rotated by the driving unit 130 in a state where the binder-coated raw material is moved by a certain amount in the bottommost mixed space of the tank 111 by repeating the above- The raw materials are mixed with each other and collided with each other by the upper blade 122b and the lower blade 122c so that the binder is finally coated on the raw material and at the same time the raw material is coated on the raw material during the rotation movement along the inner peripheral surface of the tank 111 by centrifugal force, And reaches a discharge port 114, a certain amount is discharged to the outside.

As described above, according to the present invention, in a state in which the interior of a tank having a vertical cylindrical shape is divided into a plurality of mixing spaces, raw materials supplied to the mixing space at the uppermost stage sequentially pass through the mixing space at the lower end The coating efficiency and the working efficiency can be improved as compared with the coating method of the raw material by the conventional intermittent type or non-continuous type equipment by continuously performing the operation of repeatedly covering and discharging the binder.

Although the present invention has been described with reference to the specific embodiments, various modifications may be made without departing from the scope of the present invention. Accordingly, the scope of the invention is not to be determined by the embodiments described, but should be determined by equivalents of the claims and the claims.
