Description

Technical Field [0001] The present invention relates to a device for separating iron and dust in a welding flux,

The present invention relates to an iron powder and dust separator in a welding flux, and more particularly, to an iron powder and dust separator in a welding flux, in which foreign matter, iron powder, and dust present in the flux recovered after welding are completely separated from each other by welding flux, To an iron powder and dust separation device in a welding flux capable of obtaining or providing flux.

In general, welding flux, which is a welding material widely used in industrial fields, is recovered and reused after welding. However, in the process of collecting the welding flux, not only the flux but also foreign substances such as various slags present in the workplace, dust and iron powder (iron powder) are collected together.

Korean Patent No. 1604665 entitled " Portable Welding Flux Retrieval Apparatus "and the like are known as a conventional technique for allowing the flux to be reused after removing the dust or the like.

Most prior arts including the above-mentioned known art have a structure in which dust in a welding flux is first separated by using compressed air, and then a falling welding flux is passed through a magnet member to separate iron particles in the welding flux.

However, the prior art requires a separate means (e.g., a ring blower or an air compressor) for generating compressed air, and only heavy dust is removed, and foreign substances heavier than dust fall down like welding flux, As the iron powder sticking to the magnet member can not be immediately removed, the efficiency of iron removal by the magnet deteriorates with time. Even iron powder caught on the magnet member may fall like the welding flux and still exist in the welding flux.

Therefore, it is necessary to develop a device capable of reliably separating the iron powder and the dust in the recovered welding flux so as to reliably reuse the welding flux to be reused.

That is, the principle is applied to the first filter member 20 that the sieve is shaken back and forth, or sideways and sideways, and the foreign substance is sieved through the sieve.

5 to 9, the internal structure of the device according to the present invention will be described taking two embodiments as an example.

The preferred embodiment of the present invention described below is different in its coupling structure depending on whether the roller itself is a magnet or not.

First, referring to Figs. 5, 6A, 6B and 7, an embodiment in which a magnet is separately provided inside a hollow roller will be described.

The roller 40 according to the present invention is mounted on a fixed shaft 41 which is disposed inside the main body frame 100 and below the first filter member 20 and fixed to the inside of the main body frame 100, And is connected to the first motor 410 installed on the inner side of the main body frame 100 through the power transmitting means 420 and rotated through the second roller 42.

6A and 6B, the roller 40 of the present invention traverses the inside of the main body frame 100 and includes a main body frame (not shown) 100 is rotatably supported by a fixed shaft 41 via a bearing 42. [ In one embodiment, the bearing 42 may be a known radial ball bearing.

The roller 40 of the present invention has a hollow structure with a space therein. As shown in FIGS. 6A and 6B, about half of the inner space of the roller 40 is occupied by the inner magnetic body 61. In other words, the inner magnetic body 61 of the present invention is fixed to a fixed shaft 41 penetrating the inside of the roller 40, and the outer peripheral surface of the roller 40 is formed of a magnetic region 40A and a non- (See FIG. 6B) only in the outer semi-circular region of the fixed shaft 41 in the inner space of the roller 40 so as to be divided into the non-magnetic region 40A and the non-magnetic region 40B. 6A is a longitudinal sectional view for explaining the structure of the roller 40 installed on the fixed shaft 41 and FIG. 6B is a longitudinal sectional view taken along the line A-A of FIG. 6A.

6B, the inner magnetic body 61 is fixed only to the semicircular region which is the inner space of the roller 40, so that the roller 40 has a portion facing the inner magnetic body 61, The nonmagnetic region 40B is magnetized in the magnetic region 40A while the opposite side portion or the nonmagnetic portion 40B in the opposite side to the inner magnetic body 61 does not have magnetism do.

As described above, the inner magnetic body 61 of the present invention is configured such that the outer circumferential surface or the outer circumferential surface region of the roller 40 is divided into the magnetic region 40A and the non-magnetic region 40B, And the iron particles existing in the welding flux falling from the first filter member 20 are fixed to the fixing shaft 41 in the inner region or the inner space of the roller 40 in the magnetic region 40A of the roller 40 40 and a nonmagnetic region 40B that is separated from the outer circumferential surface of the roller 40 and is a known magnet having either a polarity or a magnetic force of N pole or S pole. As an embodiment of the inner magnetic body 61, an electromagnet as well as a permanent magnet can be adopted.

5, the outer periphery of the roller 40 and the outer periphery of the non-magnetic region 40B of the roller 40 are spaced apart from each other, An outer magnetic body 62 is fixedly installed.

The outer magnetic body (62) is a magnetic body having the same polarity as the inner magnetic body (61). That is, if the inner magnetic body 61 is N pole, the outer magnetic body 62 becomes the N pole, and if the inner magnetic body 61 is the S pole, the outer magnetic body 62 becomes the S pole.

The outer magnetic body 62 has the same polarity as the inner magnetic body 61 so that the roller 40 magnetizes to the same polarity (N pole or S pole) as that of the inner magnetic body 61 A repulsive force is generated between the roller 40 and the outer magnetic body 62 so that the iron powder continuously sticking to the outer peripheral surface of the nonmagnetic region 40B of the roller 40 is attracted by the repulsive force acting between the same polarity And certainly falls off the outer peripheral surface of the non-magnetic region 40B of the roller 40. [ The outer magnetic body 62 is fixedly disposed on a bracket 64 provided inside the main body frame 100.

5, a collecting member 50 is provided between the first filter member 20 and the roller 40 in the interior of the main body frame 100. The collecting member 50 guides the welding flux falling from the first filter member 20 to directly above the roller 40. As shown in FIG. 5, the collecting member 50 has a cross-sectional area Is preferable. Therefore, the welding flux falling from the first filter member 20 by the collecting member 50 is collected at the uppermost portion of the rotating roller 40.

In the present invention, the roller 40 is rotated by the first motor 410 and the power transmission means 420. The power transmission means 420 of the present invention is connected to the motor shaft of the first motor 410 A driven pulley 422 provided on a side of the roller 40 and a driven pulley 422 connected to the driven pulley 421 and the driven pulley 422 to rotate the first motor 410 And a timing belt 423 for rotating the roller 40 by driving.

When the first motor 410 rotates by the ON control of the switch unit 130 of the present invention, the driving pulley 421 connected to the motor shaft of the first motor 410 rotates, The rotational force is transmitted to the driven pulley 422 by the timing belt 423. [ 6, the driven pulley 421 may be connected to a motor shaft of the first motor 410 through a speed reducer (not shown) (One side portion or the other side portion) of the roller 40 to rotate the roller 40 by the rotational force of the first motor 410. As a result, the roller 40 of the present invention rotates about the fixed shaft 41.

The plate cam 70 of the present invention is a known plate cam which is provided on one side of the roller 40 and rotates together on the fixing shaft 41 when the roller 40 rotates. As will be described later, in the present invention, when the plate cam 70 is rotated in a circular motion, the second filter member 80, which will be described later, becomes a follow-up period and cyclically reciprocates. 6, the plate cam 70 and the driven pulley 422 are all provided on one side of the roller 40, but only the plate cam 70 is provided on one side and the driven pulley 422 is provided on the other side Or vice versa.

The second filter member 80 of the present invention is provided inside the main body frame 100 with a downward inclination by the link member 120 and a contact hole 81 provided at one side of the upper end thereof contacts the plate cam 70, When the plate cam 70 rotates, it linearly reciprocates in an oblique direction, and the second mesh net 82 is provided to separate dust present in the welding flux.

5 and 10, one end of the link member 120 is rotatably connected to the upper portion of the second filter member 80, and the other end of the link member 120 is rotatable to one side of the main body frame 100 A pair of first link bars 121 connected at one end to the lower side of the second filter member 80 and a second end rotatably connected at the other end to the other side of the main body frame 100 5 and 10, the second filter member 80 is inclined downward in the main body frame 100 as shown in FIGS. 5 and 10, 121 and the second link bar 122 are disposed.

As shown in FIGS. 5 and 10, the link member 120 of the present invention is installed so that the second filter member 80 can be reciprocated in a diagonal direction while inclining downward from the inside of the main body frame 100 do.

5, the contact hole 81 protrudes from one side of the upper end portion of the second filter member 80, and contacts the plate cam 70. As shown in FIG. As a result, when the plate cam 70 rotates, the second filter member 80 reciprocates by the contact hole 81 as a slave end of the plate cam 70. The protruding piece (not shown) is protruded from one side of the upper end of the second filter member 80, and a radial ball bearing (not shown) is attached to the protruding piece The radial ball bearing and the plate cam 70 can be brought into contact with each other.

When the plate cam 70 rotates together with the roller 40 by the contact of the plate cam 70 and the contact hole 81, the contact member 81, which is in contact with the plate cam 70, Is reciprocated in the oblique direction shown in Fig. As a result, like the first filter member 20, dust can be effectively separated from the welding flux moving downward on the second filter member 80 by applying the principle of waving the sieve back and forth or sideways and sifting through the sieve have.

In the present invention, since the mesh size of the second mesh net 82 provided in the second filter member 80 is smaller than the particle size of the welding flux, dust or the like having a particle size smaller than that of the welding flux, 82 fall down to the dust collection box 91 arranged below.

As described above, the iron powder separated from the welding flux falls from the lower side of the non-magnetic region 40B of the roller 40 to the space S1 indicated in Fig. 5 inside the main body frame 100, The separated dust falls from the lower side of the second mesh net 82 of the second filter member 80 into the space S2 specifically shown in Fig. 5 inside the main body frame 100, and the iron dust, The welding flux falls to the space S3 shown in Fig.

Referring to Fig. 7, the operating relationship of the apparatus according to an embodiment of the present invention (when the inner magnetic body 61 is provided inside the roller 40) will be described again.

First, when the driving unit 30 is operated by the ON control of the switch unit 130 to reciprocate the first filter member 20 in the horizontal direction, various foreign substances present in the welding flux disposed in the hopper unit 10 Is separated by the first mesh net (22) of the first filter element (20) and the remaining welding flux falls off the first filter element (20).

The iron flux is stuck on the outer circumferential surface of the magnetic region of the roller 40, and the remaining welding flux falls on the second filter member 80. The iron powder I sticking on the outer circumferential surface of the magnetic region 40A of the roller 40 is separated from the outer circumferential surface of the nonmagnetic region 40B of the roller 40 where the magnetic force is extinguished, And is collected into the iron collection box 90 disposed in the iron collection box 90. The roller 40 is rotated by the first motor 410 and the power transmitting means 420 and the first motor 410 is operated by ON control of the switch unit 130. [

On the other hand, if the roller 40 becomes magnetized after the elapse of time and the roller 40 becomes magnetized, a part of the iron powder may not fall off even in the non-magnetic region 40B of the roller 40. However, Since the outer magnetic body 62 generates the magnetized roller and the repulsive force R, the iron powder not partially falling off the non-magnetic region 40B is also repelled by the repulsive force R in the space in which the repulsive force R acts, Some of the iron particles that have not fallen off the non-magnetic region 40B of the roller 40. [

Therefore, according to the present invention, even if the apparatus is used for a long time, the efficiency of iron separation due to magnetization of the roller is not lowered.

Next, the welding flux from which the iron powder dropped from the roller 40 to the second filter member 80 is separated moves on the second filter member 80 in the downward direction, The dust D separated and separated by the mesh net 82 is collected in the dust collection box 91 disposed on the lower side of the second mesh net 82. The second filter member 80 installed downwardly inclined from the inside of the main body frame 100 by the link member 120 reciprocates in the diagonal direction due to the contact with the plate cam 70. [

The welding flux F from which the iron powder and the dust are separated falls from the lower end of the second filter member 80 and is discharged from the space S3 shown in FIG. 5 or 10 or through the flux collecting box 92 shown in FIG. 7 Can be obtained.

Now, referring to Figs. 5, 8A, 8B and 9, another embodiment of the present invention will be described. The other embodiment of the present invention adopts the above-described configuration as it is, except that the structure of the roller is different, so that the overlapping structure will not be described below.

In another embodiment of the present invention, the roller 43 itself is a magnetic body having either the N pole or the S pole. That is, the inner magnetic body 61 is not provided on the inner side like the roller 40. 5 and 8A, except that a magnetic body is not provided on the inner side of the roller 40, the second roller 41 is formed on the fixed shaft 41 via a bearing 42, Is rotated through the transmission means (420), and a plate cam (70) is installed at one side.

5 and 8B, the stationary magnetic body 63 is spaced apart from the roller 43 so as to be opposed to the roller 43, and the main body frame 100 ) Through a bracket (64). The fixed magnetic body 63 is a magnetic body having the same polarity as the roller 43. That is, if the roller 43 is an N pole, the stationary magnetic body 63 is also an N pole, and if the roller 43 is an S pole, the stationary magnetic body 63 becomes an S pole.

As described above, since the roller 43 and the fixed magnetic body 63 have the same polarity, a repulsive force R is generated between the roller 43 and the fixed magnetic body 63. 9, when the iron powder adhering to the roller 43 rotates and comes to a position where the repulsive force R acts between the roller 43 and the fixed magnetic body 63, And is separated or separated from the outer peripheral surface of the roller 43 at all.
