Description

The grinding system and grinding method of minerals for welding solvents {COMMINUTION SYSTEM AND COMMINUTION METHOD OF MINERALS FOR WELDING FLUX}

The present invention relates to a grinding system and a grinding method of minerals for welding solvents, more preferably, minerals flowing into the inlet of the transfer machine are not loaded onto the transfer screw and are transferred to the grinding machine smoothly when discharged. It relates to a grinding system and a grinding method of a mineral for a welding solvent for grinding into uniform minerals, and discharging by sorting with a mesh separator, as well as feeding back the unsorted minerals back to the grinder for grinding.

In general, arc welding is performed. This is a high temperature caused by the current when a current is applied between the welding rod and the welding solvent (base material), and this high temperature melts the welding rod to join metals. , The welding rod is made of the same material as the welding base material, and the coating material is wrapped in the welding rod, so this coating material generates gas at high temperature to prevent intrusion of oxygen nitrogen in the air, and to form slag to oxidize and nitrate the welding area. And it prevents the deformation of the welding part due to rapid cooling, improves the fluidity of the welded metal, and acts as an insulation to prevent an electric shock accident caused by a high voltage by the operator when welding in a narrow place.

On the other hand, a mineral powder is used as the coating material, and the mineral is mainly titanium oxide, which is contained in a titania raw material or mixture, and the mineral is widely used as a raw material for a welding material. In addition to that, titanium oxide. Minerals such as silicon dioxide, alumina, and calcium oxide are mixed and used.

As one of the techniques for pulverizing such minerals into fine powder, the "multi-layer growth welding method for manufacturing and repairing the pulverized pulverization roll and table liner" of Korean Patent No. 10-0862975 is disclosed.

As described in the prior art of the above registered patent, the conventional pulverizing roll 104 or table liner 105 of the conventional pulverizer is a cemented carbide growing welding material on the base material 101 as shown in Figs. 6(A) and (B). 102) is a welded structure.

However, the conventional manufacturing and repair structure of crushing rolls and table liners is generally suitable for up to two times of repair after 20,000 hours of operation is completed. Accordingly, there is a high possibility of causing peeling due to poor welding of the welding layer. In particular, there is a problem in that the operation time cannot be extended due to the possibility of fracture and wear of the welding layer easily.

In addition, the pulverization roll does not mention any technology for preventing abrasion of the inner wall surface of the pulverizer.

In addition, according to the contents disclosed in Registration Patent No. 10-1061205 as a crushing device for crushing minerals, in general, minerals quarried using explosives such as dynamite at places such as mines are again requested by the user using a pulverizer. It has a grinding process of grinding to an appropriate size.

In addition, the crusher used in the crushing process includes a jaw crusher that crushes relatively large chunks of minerals, and a hammer crusher that crushes minerals crushed from these jaw crushers into smaller sizes.

Among them, the hammer crusher is composed of a body, a rotor (rotator disk) rotatably mounted inside the body, and a hammer mounted on an outer surface of the rotor at intervals.

That is, the hammer crusher uses the rotational force of the hammer that works in conjunction with the rotor to make the raw stone have a particle size less than a certain size.

However, the hammer crusher has a problem in that the hammer for crushing the raw stone is integrally configured, so that when the raw stone is damaged due to crushing, the whole must be replaced.

The conventional hammer for a hammer crusher has a problem in that the manufacturing cost and the replacement cost are increased because it has to be replaced frequently when the rough stone is crushed by the operation of the rotational force.

In addition, although the abrasion on the inner wall surface of the crusher during the pulverization operation is severe, there was no technology composition to protect the inner wall surface.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily practice. However, the present invention may be implemented in various different forms, and is not limited to the embodiments described herein.

The main configuration of the crushing system having a sorting function while increasing the crushing efficiency of minerals according to the present invention is a transport pipe 300 for transporting the minerals input to the hopper 100, and the transport as shown in FIG. A crusher 400 for crushing the minerals transported through the pipe 300, a mesh sorter 700 for sorting the minerals crushed in the crusher 400 into a mesh network, and the mesh sorter 700 It consists of a feedback circulation pipe 710 that feeds back minerals to be pulverized.

The main configuration according to the present invention will be described in detail through the drawings as follows.

As shown in FIGS. 1 and 2, the configuration of the hopper 100 for injecting minerals is in the lower part of the hopper 100 in order to allow the minerals to be injected only in one direction from the inside of the hopper 100. The guide inclined plate 120 is formed to be inclined on the upper side of the formed inlet 110, and the guide inclined plate 120 has a lower side of the guided inclined plate 120 at a point 1/2 in one direction (front) from the inner center. It is located and the upper side is configured by fixing it to the inner wall at an angle of 30 to 45°.

The reason is that the size of the mineral for the welding solvent is not constant, so that the input hopper 100 and the transfer screw 320 driven in the transfer pipe 300 are caught and a large load is generated on the transfer screw 320. to be.

Therefore, in the present invention, the minerals injected into the hopper 100 are not directly input vertically to the rear side of the transfer pipe 300 at the inlet 110 of the hopper 100, but along the inclined surface of the guided inclined plate 120 ( Since it is introduced to the front of 300), by reducing the occurrence of minerals and shortening the transport distance, the transport is driven by receiving the power of the motor 310 inside the transport pipe 300 and the transport pipe 300 It is to reduce the load on the screw 320 so that the driving of the transfer screw 320 can be achieved smoothly.

In addition, as shown in Figure 2, the configuration of the transfer pipe 300 for transporting the minerals input from the hopper 100 has a larger diameter of the outlet 340 than the diameter of the inlet 330 inside the transfer pipe 300. By forming, since the transferred mineral is widely spread and transferred as it goes forward, transfer can be made smoothly.

And the structure of the crusher 400 for pulverizing the minerals moved through the transfer pipe 300, as shown in Figure 4, the diameter than the central axis 410 and the central axis 410 rotated by receiving the power of the motor Using the enlarged disk shaft 420 and the disk shaft 420 as coaxial, a plurality of rotating disks 430 are installed spaced apart from each other.

A plurality of hammer shafts 441,/442/443/444 are installed on the same circumference about the central shaft 410 in the rotating disk 430 in parallel in the same direction as the central shaft 410.

Further, the hammer 450 is coupled to the hammer shaft 441, /442/443/444 so as to be able to rotate relative to each other.

When explaining the structure of the crusher 400 to be worse,

It consists of a central shaft 410 that rotates by receiving the power of a motor and a disk shaft 420 whose diameter is larger than that of the central shaft 410, and the disk shaft 420 is concentric with the central shaft 410 but has a diameter By further expanding the torque according to the rotation of the rotating disk 430 directly coupled to the disk shaft 420 can be reduced, thereby reducing the physical impact applied to the disk shaft 420.

The disk shaft 420 is provided with a plurality of disk-shaped rotating disks 430 at regular intervals, which form a hole having the same diameter as the diameter of the disk shaft 420 in the center of the circular plate. After extrapolating to the disk shaft 420 through the hole, the portion in which the disk shaft 420 and the rotating disk 430 come into contact may be coupled through welding or the like.

And the rotary disk 430 has a plurality of hammer shafts 441, /442/443/444 installed parallel to the central shaft 410, and the hammer shafts 441, /442/443/444, which are installed in plurality, are It is installed on the same circumference with respect to the central axis 410, and each hammer shaft is arranged and installed at a predetermined interval, that is, a predetermined angle.

Preferably, four hammer shafts 441, /442/443/444 are installed on the rotating disk 430 at 90° intervals as shown in FIG. 4B.

The combination of each of the hammer shafts (441/442/443/444) is to form a hole so that the hammer shaft can be forcibly fitted in the same circumference radially with respect to the center of the rotating disk 430, and the hole In a state in which a plurality of the formed rotating disks 430 are coupled to the disk shaft 420 at regular intervals, a hammer shaft is inserted through the hole to be coupled.

The hammer shaft 441/442/443/444 interpolated across the rotating disks 430 installed at regular intervals is coupled with a hammer 450 for crushing minerals, and the hammer 450 is at one side A hammer shaft hole 452 that is extrapolated to the hammer shaft 441/442/443/444 is formed, and a chrome brobar 451 is mounted at an end of the hammer 450 in the rotational direction. This is because the part of the hammer 450 that comes in contact with the mineral is severely abrasion when the mineral is crushed, so that the part that comes into contact with the mineral forms a chromium brobar 451 having strong strength, and the chrome bro bar 451 is the hammer 450 It can also be mounted on the body by disassembling/combining.

In addition, as shown in the enlarged view of the hammer 450 of FIG. 4, the chrome brobar 451 mounted to the hammer 450 has a serrated and convex surface 451d in order to widen the contact surface to which the mineral is hit. Can be formed by That is, the uneven surface 451d includes a valley portion 451c and a ridge portion 451a, and an inclined portion 451b connecting the valley portion 451c and the ridge portion 451a.

When the chrome brobar 451 of the hammer 450 is formed as the uneven surface 451d, the area in which the mineral to be crushed is in contact with the hammer is increased, and structurally, the mineral crushed while the mineral collides with the floor part 451a is Sliding inside the valley part 451c while riding the inclined part 451b, disturbance is generated between the particles according to the size of various particles of the pulverized mineral. As it is discharged to both ends of ), the fine powder collides again by the eddy current with air, maximizing the grinding efficiency.

The hammer 450 coupled by extrapolating the hammer shaft hole 452 to the hammer shaft 441/442/443/444 is able to rotate relative to the hammer shaft, and one rotating disk 430 and a rotating disk 430 Only one hammer 450 is installed between, that is, there are four hammer shafts (441/442/443/444) between one rotating disk 430 and the rotating disk 430, but one of the four hammer shafts The hammer 450 is coupled only to the shaft. Preferably, the hammer 450 coupled to the same hammer shaft 441 is coupled by skipping four rotating disks 430 as shown in FIG. 4A.

In the hammer 450 installed in this way, when the central shaft 410 rotates by motor power, the hammer 450 coupled to the hammer shaft 441/442/443/444 is rotated in conjunction with the central shaft 410.

Here, the rotating disk 430 serves as a guide so that the hammer 450 coupled to each hammer shaft does not tilt left and right during rotation, thereby preventing collisions between adjacent hammers 450 and effectively colliding with the hammer 450 and minerals. Improves its crushing efficiency.

And the configuration of the crusher 400 for crushing the minerals moved through the transfer pipe 300, as shown in Fig. 3, a rotating disk 430 that rotates by receiving the power of a motor, and the rotating disk 430 A hammer 450 for crushing by hitting the mineral is mounted in front of the. At this time, in order to increase the strength of the hammer 450, a chrome brobar 451 is mounted at an end of the hammer 450 in the rotational direction. In addition, the hammer 450 is configured by mounting on one side of the central portion of the front end of the rotating disk 430.

Before describing the configuration of the crusher 400 according to the present invention, the reason for selecting the material of the hammer 450 for grinding by hitting minerals will be described.

1) Material selection for development of mineral grinding hammer

In general, a hammer for crushing minerals has a process of colliding with minerals by high-speed rotation, so the possibility of damage by impact is high, so strength and impact value must be considered.

And generally, the material of the grinding roll is made of SKD11 steel, which is a tool steel for cold-molding, and compared with other materials, it is intended to be used to select an appropriate material.

As shown in the following [Table 1], a comparison of tool steel types and properties is as follows.

In addition, the chemical composition system of SKD11 is as shown in [Table 2], and the alloy and composition system of steel are factors that have a great influence on the mechanical properties, so they are important considerations.

Meanwhile, the influence of alloying elements in steel is as follows.

-In the case of chromium (Cr), if it is contained in steel, it can improve corrosion resistance and make chromium-based carbides, thereby improving high hardness wear resistance.

-Molybthene (Mo) is known as an element that greatly helps improve mechanical properties such as wear resistance and hardness when added with chromium.

-In the case of carbon (C), it is the first element that increases the strength of steel.

-Phosphorus (P) and sulfur (S) are elements that damage the cleanliness of steel and cause brittleness.

⊙ Hardness test

-An important physical property that determines wear resistance is hardness, which is intended to measure the hardness of each specimen.

-Conduct Vickers hardness test by 5 points for each specimen: measurement load 1000gf (load range: ~Max.2000)

⊙ Impact test

-To select the material for the crushing hammer, we want to check the impact resistance characteristics of the candidate group (steel).

-In the process of crushing minerals with their own hardness, impact resistance must be maintained above a certain level in order to increase resistance to collisions with minerals and to secure durability.

-Test specimens are prepared as standard specimens for Charpy impact tests for candidate groups.

-The test is conducted in Charpy V-notch standard (ASTM E32), and the shape of the test piece is as follows.

<Sharpy V-notch test piece shape and standard>

2) Selection of crushing target

⊙ Compression test

-Conducted compression tests on silicon manganese, ferromanganese and chromium

-MTS UTM use, load record

-As a result of the test, silicon manganese and ferromanganese break under low loads (6kN, 14kN), but chromium does not break even under considerable loads (100kN or more).

-It is expected to give the biggest impact as chrome does not break when crashed

3) hammer design

⊙ Finite element analysis of hammer

-Purpose: Calculation of the stress applied to the hammer when chrome hits the hammer

-Program used: Abaqus Standard and Abaqus CAE

-The mechanical properties used in the analysis are as follows

Contents SM45C (hammer material) Chromium density 7.8 g cm ^-3 7.1 g cm ^-3 The tensile strength 490 MPa 689 MPa Young's modulus 210 GPa 279 GPa Poisson's ratio 0.3 0.21

According to the experiment as described above, in the present invention, a chrome brobar 451 is mounted in the direction of rotation of the hammer 450.

Therefore, in order to increase the strength of the hammer 450, the chrome brobar 451 having the serrated uneven surface 451d is mounted in the rotational direction to reinforce it and improve abrasion resistance. Therefore, by extending the life of the hammer 450, it is possible to improve the grinding efficiency by reducing the replacement time of the hammer 450.

In addition, since the inner surface of the crusher 400 is highly abrasive, a cover 470 that is detachable from the inner surface of the crusher housing 460 is mounted. Therefore, when the cover 470 is worn while hitting the mineral with the hammer 450, only the cover 470 can be replaced and used, so that the durability of the crusher 400 itself can be improved.

And the configuration of the discharge pipe 500 for transporting the minerals pulverized and discharged by the pulverizer 400 to the mesh sorter 700 made of a mesh network is a free fall method when moving the powdered mineral pulverized inside the pulverizer 400 Since there is a possibility of material loading on the intermediate connection when transferring to the transfer machine of the machine, the transfer method to the transfer machine was configured as a transfer screw tube transfer method. That is, the discharge screw 510 is formed inside the discharge pipe 500. Therefore, it is possible to prevent congestion.

In addition, the configuration of the vertical transfer pipe 630 for transporting the minerals discharged through the discharge pipe 500 to the mesh sorter 700, as shown in Figs. 1 and 5, by receiving the power of the motor vertically. A plurality of buckets 610 are formed at intervals between the rotating body 620.

In addition, a guide tube 630 for guiding the pulverized minerals through the vertical transfer tube 600 to the mesh separator 700 is configured by connecting the vertical transfer tube 600.

And looking at the configuration of the mesh sorter 700 for sorting the pulverized minerals induced through the guide tube 630 into a predetermined size, as shown in Figure 3, the mesh sorter 700 has a mesh network inside. The selected minerals are discharged through the finished product discharge port 720 at the bottom, and at the same time, the selected minerals are formed in a feedback circulation pipe 710 formed at the upper one side of the mesh sorter 700. It is configured to be circulated through the crusher 400 to be pulverized again.

Here, a plurality of mesh nets in the mesh separator 700 may be installed from top to bottom for each standard, and when there are a plurality of mesh nets, it is natural that a plurality of feedback circulation pipes 710 are also installed, preferably mesh net 2 It is preferable to install two feedback circulation pipes 710 in each dog.

The operating state of the pulverizing system having an automatic sorting function of minerals according to the present invention configured as described above will be described with reference to FIGS. 1 to 5 as follows.

As shown in FIG. 1, when minerals are injected into the hopper 100, the minerals are transferred to the inlet 110 along the guided inclined plate 120 installed at a point 1/2 in front of the center instead of the center of the hopper 100. Is put in. Therefore, the mineral is input to the front of the inlet (110).

The mineral injected into the front of the inlet 110 is introduced into the transfer pipe 300 mounted under the hopper 100. At this time, the transfer screw 320, which is driven by receiving the power of the motor inside the transfer pipe 300, does not apply a load, so that the drive is smoothly performed. Therefore, the mineral introduced into the transfer pipe 300 is transferred forward by a transfer screw 320 driven by receiving the power of the motor 310.

In addition, since the diameter of the outlet 340 is larger than the diameter of the inlet 330 of the transfer pipe 300, the transfer is smoothly performed. That is, since the mineral spreads more widely as it is transferred to the front, the ejection is smoothly performed.

The mineral transferred through the transfer pipe 300 flows into the crusher 400, and the introduced mineral is a hammer coupled to the rotary disk 430 driven by receiving the power of a motor from the inside of the crusher 400. It is crushed while being hit by the hammer 450 coupled to the shaft 441/442/443/444 so as to be relatively rotatable. At this time, in order to increase the strength of the hammer 450, a chrome brobar 451 having a serrated and convex surface 451d is mounted in the rotation direction of the hammer 450, so that when striking the mineral, the strength is high to prevent abrasion. Can be delayed. Therefore, since the life of the hammer 450 can be extended, work efficiency can be improved.

And the mineral pulverized in the crusher 400 is discharged along the discharge screw 510 of the discharge pipe 500 and transferred to the vertical transfer pipe 600, the mineral transferred to the vertical transfer pipe 600 rotates inside. It is transferred to the bucket 610 mounted on the rotating body 620 and transferred to the mesh sorter 700 through the guide tube 630 to perform a sorting operation in a predetermined size.

The minerals powdered to a certain standard selected by the mesh sorter 700 are discharged to the finished product discharge port 720. In addition, the minerals that have not been sorted are again introduced into the pulverizer 400 through the feedback circulation pipe 710 to perform pulverization.

Briefly describing the pulverization method according to the present invention that operates as described above is made of the following processes.

The present invention consists of a step of injecting minerals to the front of the hopper 100 through the inlet 110 to the guide inclined plate 120 installed at the center front 1/2 point instead of the center of the hopper 100.

An outlet having a diameter larger than the diameter of the inlet 330 of the transfer pipe 300 so that the mineral input through the inlet 110 can be smoothly transferred to the transfer screw 320 driven by receiving the power of the motor 310 ( It consists of a step of discharging into the interior of the crusher 400 through 340.

Minerals introduced into the inside of the crusher 400 are crushed by striking the chrome brobar 451 mounted in the rotational direction of the hammer 450 coupled with the rotating disk 430 that rotates by receiving the power of the motor. In the pulverization process, in order to prevent abrasion of the inner wall of the pulverizer housing 460, a removable cover 470 is formed in the pulverizer housing 460, and the cover 470 is replaced when the cover 470 wears to perform pulverization. .

It consists of discharging the minerals crushed in the crusher 400 through the discharge screw 510 of the discharge pipe 500.

After transferring the minerals discharged through the discharge screw 510 to the bucket 610 mounted on the rotating body 620 rotating inside the vertical transfer pipe 600, the mesh separator ( 700).

The minerals sorted by the mesh sorter 700 are discharged to the finished product discharge port 720, and the minerals that have not been sorted are again introduced into the crusher 400 through the feedback circulation pipe 710 and pulverized.

In the present invention, which consists of the above steps, the minerals injected into the hopper can be transferred smoothly without applying a load to the transfer screw, and the minerals are crushed by hitting the minerals with a hammer equipped with a chrome burrow during the grinding operation, so that the abrasion resistance as well as strength By increasing the hammer, it is possible to extend the life of the hammer and improve work efficiency. In addition, since the pulverized minerals are automatically sorted into a certain size through the mesh sorter, and the aggregate that has not been sorted can be fed back to the pulverizer and pulverized again, the sorting efficiency can be improved.

As described above, a detailed description of the present invention has been made by an embodiment with reference to the accompanying drawings, but since the above-described embodiment has been described with reference to a preferred example of the present invention, the present invention is limited to the above embodiment. It should not be understood as.
