Description

A MAGNET DEVICE FOR SELECTING IRONWARE USING FEED RAW CRUSHER}

The present invention relates to a hardware removal magnet device for feed mill, more specifically, to smoothly and accurately remove iron, iron, and the like from the feed material evenly spread before the mill is added to prevent breakage of the grinder, grinder blade, screen, The present invention relates to an iron removal magnet device for a feed mill, which is improved to prevent the incorporation of iron into the feed in advance to prevent the hazards to livestock.

In general, the grinder used in the processing of the feed material is a device configured to grind the feed material introduced through the hopper through a rotating grinding blade, and to separate by the particle size through the screen.

As such, in order to grind the feed material, it is necessary to have a relatively large facility including a device for supplying the feed material, a device for removing iron, such as iron and iron scraps included in the feed material, and a device for grinding the feed material.

At this time, the three devices described above are components having a very important correlation that has a close effect on the grinding efficiency, the durability of the mill, etc., the applicant has a patent application No. 2011-0078405 with respect to the raw material supply.

This ensures that the amount of feed material fed into the grinder is linearly quantified to minimize the load fluctuations applied to the grinder, thereby suppressing pulsations to increase the grinding efficiency and to smoothly and uniformly grind the grinder while extending the life of the grinder. It is made up.

Therefore, if the iron removal magnet device disclosed in the present invention is used in conjunction with the linearly supplied metering device supplied by the applicant of the present applicant will have even more excellent efficiency because the collecting ability through the magnet will be maximized.

However, even if the magnet device according to the present invention is applied to the existing structure as it is, it has a significantly improved collection ability compared to the existing magnet device.

Prior to describing in detail, a description will be given of an iron removing magnet device disclosed in the related art.

Representative examples of the conventional iron removal magnet device may be a general form in which a magnetic material such as iron or iron pieces are selectively removed by a magnetic force by attaching a magnet on a passage through which feed material is supplied toward a grinder.

However, such a structure has a disadvantage in that the work of having to separate and remove the iron adsorbed on the magnet directly after the work is very cumbersome and difficult.

In order to solve this problem, it was improved to the structure that can open and close only part of the magnet installed from the passage, but because the hardware is strongly adsorbed, it is not easy to shake off or remove, and the raw material itself Due to its coarse and many kinds of by-products and low price, feed materials have a relatively high amount of impurities and impurities generated during the process. Especially, among them, the contact area with magnets such as bearing balls, bolts, nuts, screws, etc. is small and the cloudiness is good. In the case of hardware, the sorting efficiency was very low because they could not be adsorbed and rolled off.

In addition, for this reason, when the iron is introduced into the grinder, not only the grinding blade is broken, but also the grinder is broken, which leads to equipment accidents, which incurs huge repair costs, yield drops due to work delays, and delayed delivery time. Etc., causing huge losses.

As another example, there is a metal foreign material removal device shown in Registered Utility Model No. 0440009 (Utility Model Registration Application No. 2006-0032961).

According to the registration scheme, the cylindrical magnet is installed on one side of the lower part of the feeder for supplying the feed material, and has a structure removed by cutting a part, and installs a rotating drum surrounding the magnet, and a rotating flow plate below the rotating drum. When the hardware contained in the feed material that was dropped by moving is moved on the rotating drum surface, and reaches the cut-out part of the magnet, the magnetic force is lost and falls to the lower side, but the centrifugal force goes over the operating plate and falls into the feed material and the space partitioned. It can be seen that it is configured to separate and remove the iron contained in the feed material.

However, this registration scheme is not only complicated in structure, but also requires the use of a separate power source, and there is a lot of trouble in processing the housework because the housework is piled up inside, and also a relatively large amount of feedstock is supplied to the grinder. Since it has to be installed in a volume, it reduces the feeding efficiency and reduces the overall grinding efficiency, and above all, the hardware such as bearing balls, bolts, screws, nuts, etc., which have good rolling properties, remain attached to the drum surface having a circular shape. Because it is not easy to be rolled off and falls off, it is difficult to obtain the effect described in the registered patent. However, if the iron in powder is already attached to the surface of the rotating drum during the processing of the feed material, the magnetic force drops by the thickness (usually magnetic force). Is inversely proportional to the square of the square), in addition to circular hardware It is so down rolling ride rather than being stuck because of proximity to attach almost point-contact part of the non-contact surface that usually is difficult to obtain a screening effect as that patents are presented, perceiving it real test, which was found to be obvious.

As another example, the practical publication No. 1981-0001754, 'iron removal device in the feed', and '0357793' feed compounder 'for the registration room are disclosed, but in the case of the former, the electromagnet in the normal transfer process, not the feed grinding process It is understood that the process of screening hardware using rollers has little relevance to the present invention due to the characteristics of the process, and as described above, there is no method of eliminating the sliding of the hardware in the case of a roll-shaped magnet. have.

In addition, the latter case relates to the compounding machine itself, which is not only a structure in which a permanent magnet is attached to an inner feeding spiral blade, which is clearly different from the field to which the present invention belongs, and that the efficiency or installation structure itself is different and classified as a prior art of the present invention. It is difficult to do.

In addition, the price of magnet is inevitably higher as the Gauss is higher. Recently, the rare earth-producing countries such as China have continuously raised the price, so it is impossible to use magnets with infinite magnetic force. There is a continuous demand for the development of the device, which leads to a need for cost reduction.

The present invention was created as a part of the product made by the inventors through a lot of efforts to solve this problem in consideration of various problems in the prior art as described above, HACCP (Hazard analysis and critical managed by the Food and Drug Administration In order to meet the control points, the quality of the feed is improved by completely blocking and separating the round metals from entering the feed material grinding process, and preventing damage to the devices constituting the grinder. Since the operation efficiency of the crusher is improved, the yield is not improved and there is no need for a separate power source, so it is also simple in structure, easy to install, easy to separate and remove the adsorbed iron, and contribute to the reduction of maintenance cost. Removal of iron for new types of feed mills Its main purpose is to provide a magnet device.

The present invention is a means for achieving the above object, is installed on the magnet flow path provided between the hopper to feed the feed material and the pulverizer for crushing the feed material feed adsorbed to the iron material mixed in the feed material separated by a magnet What is claimed is: 1. An iron removal magnet device for a feed mill to be removed; An incision is formed on the side of the magnet channel in which the feed material falls and collides; The gate is installed so as to be rotated by its own weight about the hinge axis on the outer side of the magnet channel to open and close the incision, the gate is a non-magnetic material of the hollow inside, the magnet of the magnet channel to open and close the incision The gate is installed so as to be rotated by its own weight about the hinge axis at the outer surface, the gate is an internal hollow nonmagnetic material, and the stairs are in the vertical direction of the gate on the exposed surface of the gate exposed to the magnet flow path. The step is formed, but the exposed surface of the gate becomes the iron adsorption surface, and the lower part of the gate becomes the circular iron adsorption surface, and the lower side forming the circular iron adsorption surface forms the iron adsorption surface. Thinner than thickness; The magnet housing is rotatably installed coaxially with the gate, and the magnet housing has a structure that is respectively inserted into the iron adsorption surface and the circular hardware adsorption surface of the gate, and a plurality of magnets spaced apart from each other are embedded therein The first magnet corresponding to the suction face is a plate magnet thicker than the second magnet corresponding to the circular hardware suction face; One end is hinged and fixed to the outer side of the magnet flow path, the other end is provided with an opening and closing cylinder so that the cylinder rod is retractable, the end of the cylinder rod is hinged fixed to one side of the magnet housing Provide a removal magnet device.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the equipment constituting the pulverizer associated with the present invention is a feed material drawn from the hopper (H), the hopper (H) for receiving the feed material for feeding the feed material toward the pulverizer (not shown) Rotor housing 200 with a built-in pocket feeder (not shown) for supplying a fixed amount, and a magnet euro (G) for guiding feed raw materials fed through the rotor housing 200 to the grinder, and a magnet euro ( G) a grinder is installed below, and the magnet device M of the present invention is installed on the magnet channel G.

In this case, reference numeral '110' is a rotor rotation shaft, '210' is a rotor partition wall, 'B' is a bypass passage for directly connecting the hopper and the grinder.

The present invention has been devised in a multi-faceted manner to solve the above problems in consideration of various problems of the prior art.

Nevertheless, the implementation of a magnet device having an effective, efficient and simple structure has been quite difficult.

However, it was possible to secure the ease of cleaning, which allows one side of the magnet channel (G) to be opened and closed so that the equipment idles when the feed material is changed, and at that moment, one side of the magnet channel (G) where the magnet is installed is opened. And, by removing the magnetic force it was possible to efficiently implement in the form of repeating the process of dropping the adsorbed iron by the weight in the downward direction.

However, the rounded hardware is adsorbed by the magnetic force, but because of its good cloudiness, it is easily rolled down and is not screened out and eventually mixed back into the feed material. I couldn't.

Therefore, when forming the triangular protrusion jaw (D) in the form as shown in Figure 2 (a) to allow the iron (F) to be expected to be able to prevent the rolling down, but feed material should flow down smoothly Since the upper end of the protruding jaw D can only be formed to be inclined, the hardware F can be rolled and stayed at the vertex of the protruding jaw D, and then the square of the distance as shown in FIG. Even when using the magnet 400 having a large magnetic force due to the magnetic force inversely, due to the magnetic force that decreases exponentially with distance caused a problem that the adsorption force (collective capacity) is lowered.

That is, the distance d2 from the magnet 400 to the vertex of the protruding jaw D compared to the distance d1 from which the feed material is contacted, although it is not a big difference, Inversely, since the magnetic force decreases, in this case, the magnetic force is weakened, and it was confirmed that the adsorption force of the iron (F) is rapidly dropped.

Thus, after tens of tests and hard work, I came up with the idea of minimizing the distance from the magnet 400 so as not to roll the circular iron F. It is a simple structure, but it is a very difficult idea to think about it. It was obvious that it was not easy because it had to go through the process of conversion.

In other words, the example of the projecting jaw (D) described above was also in the process of conception of the present invention, which has not been carried out in the prior art. The results of the test exceeded expectations.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated more concretely.

In fact, the circular iron F, for example, the bearing ball F1, the bolts F2, the iron pieces F3, etc. as shown in FIGS. 3 to 5 are completely on the magnet channel G due to the magnetic force of the magnet 400. Never fall off, ie free fall. However, due to the magnetic force of the magnet 400 is attached to the magnet 400 side, but close to the point contact, so the magnetic force is not enough, so that it is not maintained in a completely adsorption fixed state, as well as to collide with the feed material falling into the grinder This only causes the phenomenon of rolling down due to insufficient magnetic force, but because of the presence of iron (F0) that is adsorbed first.

Accordingly, the present inventors devote themselves to finding a way to minimize the effect of iron (F0) while reducing the distance, paying attention to the staircase shape, when the stepped shape of the iron (F0) in the corner portion having a step The possibility of the present invention was predicted by the fact that they gathered while concentrated rather than riding.

Above all, the collecting capability of the magnet 400 is the distance between the magnet 400 and the hardware (F) is a major concern is how to shorten the distance.

The magnet device M according to the present invention has a large rectangular hole shape by cutting a portion of one side of the magnet channel G, preferably in contact with the feed material falling when the feed material falls, as shown in FIG. 3. A cutout 310 is formed, and a magnet housing 320 capable of opening and closing the cutout 310 is provided.

At this time, the magnet housing 320 is made of a non-magnetic material, the inside of the plurality of magnets 400, for example, a smaller size (thickness than the pair of the first magnet 402, the first magnet 402 spaced apart) 2) of the second magnet 404 is built in, the upper end is hinged rotatably around the hinge axis 330 on the outer surface of the magnet flow path (G).

Here, the magnet 400 is preferably a plate type magnet, and the first and second magnets 402 and 404 are all the same permanent magnet.

In particular, the front surface of the magnet housing 320, that is, the surface sealing the cutout 310 is 1/3 of the entire length, preferably from a third point from the lower end of the front side to the upper end It has a step to have a thinner thickness (which can be seen as the left and right width in the figure), the upper side constitutes the iron adsorption portion 406 for adsorbing the powdered iron powder, the first magnet 402 is embedded, the lower side is circular A circular hardware adsorption part 408 is configured to adsorb the hardware on the phase and a second magnet 404 is embedded therein.

To explain more easily, it becomes a step shape of thinner shape.

At this time, the portion where the magnetic force is formed is a space between the pair of the first magnet 402 provided at intervals, the space between the lower first magnet 402 and the second magnet 404, the magnet corresponding to the electron space The front part of the housing 320 becomes the iron adsorption part 406, and the front part of the magnet housing 320 corresponding to the latter space becomes the circular iron adsorption part 408.

The rear end of the opening / closing cylinder 340 is rotatably hinged on one side outer surface of the magnet channel G, and the cylinder rod 350 that is protruding is provided at the front end of the opening / closing cylinder 340. An end of 350 is hinged to a portion of the magnet housing 320.

Therefore, when the cylinder rod 350 enters the opening / closing cylinder 340, the magnet housing 320 seals the cutout 310, and when the cylinder rod 350 is drawn out from the opening / closing cylinder 340. As shown in FIG. 5, the magnet housing 320 is opened to open the cutout 310.

On the other hand, the front of the magnet housing 320 is provided with a gate 420 of the structure that can be opened while rotating up to a certain period by the magnetic force between the hinge shaft 330 and the magnetic force between the hardware and the magnet.

The gate 420 is a means for directly closing the cutout 310, and is a member having a surface in direct contact with the feed material and irons to be transported, and the front end of the magnet housing 320, that is, the first The rear side of the gate 420 is opened in such a manner that the first and second magnets 402 and 404 are embedded therein.

In addition, the gate 420 is formed of stainless steel (SUS) having no wear resistance and magnetism, and does not have its own power. That is, when the magnet housing 320 is opened by the opening / closing cylinder 340, the magnet channel G is inclined so that the gate 420 is centered on the hinge shaft 330 by the magnetic force and the magnetic force between the hardware and the magnet. It is opened while being rotated in a counterclockwise direction, and when closed, the magnet housing 320 is closed and inserted into the rear of the gate 420 by the opening / closing cylinder 340 and simultaneously pushes together with the magnet housing 320. Will be closed together.

To aid understanding, present a site installation picture as shown in Figure 6a, b showing an example of the actual application, it will be more easily understood.

In addition, a portion of the upper end of the gate 420 rotatably assembled to the hinge shaft 330 is rounded so as not to prevent the gate 420 from being rotated. In other words, the round processing is performed so that it does not interfere with the outer surface of the magnet flow path G, that is, does not get caught so that it can be rotated smoothly, but the round processing is such that the gate 420 can be opened in a vertical state. It is most preferable to form only.

In addition, as shown in FIG. 4, the front surface of the gate 420, that is, the surface exposed on the magnet channel G through the cutout 310 to have a step corresponding to the step formed in the magnet housing 320. For example, the iron adsorption surface 422 is formed at a position corresponding to the iron adsorption portion 406 described above, and the circular iron adsorption surface 424 is formed at a position corresponding to the circular iron adsorption portion 408. .

In addition, the front top of the gate 420, that is, the upper end of the iron adsorption surface 422 further includes a slope inclined surface 426 so as to smoothly guide the falling feed material is not accumulated, the bottom, that is, the On the lower side of the circular hardware adsorption surface 424, the projections 428 are protruded or attached, the projections 428 is the feed material that is poured into the interface between the lower end of the gate 420 and the cutout 310 outside In order to protect the part by minimizing the step that occurs when the gate 420 is closed due to the thickness of the magnet flow path (G) cut in order to prevent leakage into the furnace to minimize leakage.

On the other hand, the induction guide 430 is further installed at the inlet side of the magnet flow path (G) to guide most of the feed material to be transferred via the magnet 400 side, if the length of the induction guide 430 is too long Since the load is severely applied, the induction guide 430 may not only be damaged, but also may be limited to a specific length or less. In this case, the amount of feed material scattered by the drop collision may increase, in which case the hardware is separated. Since the removal effect is insignificant, the flow flap 432 that can be freely rotated at the lower end of the induction guide 430 may be further provided in the form of a shaft or the like fixed to the pin in order to further improve the efficiency.

At this time, one end of the induction guide 430 is firmly fixed to the flange portion of the inlet of the magnet channel (G), the other end is extended in the form toward the center of the magnet channel (G) is arranged in an inclined extension form.

As such, when the flow flap 432 is further provided, the feed material scattered collides with each other and the flow flap 432 flows to prevent scattering while the feed material flows in the form as shown in the drawing, so that the entire feed raw material has to go through the magnet 400. As such, the screening effect can be increased by that much.

The present invention having such a configuration has the following operational relationship.

3, 4 and 5, the gate 420 and the magnet housing 320 is kept closed when the feed is quantitatively supplied.

In other words, the incision 310 is maintained in a closed state, so that the feed material falls and flows down after most of the contact with the front surface of the gate 420 by the induction guide 430 and the flow flap 432. It enters into the grinder through the magnet 400 in the form.

At this time, the powdered iron powder (F0) is to be adsorbed on the iron adsorption surface 422 of the gate 420, as shown in Figure 4, bearing balls (F1), bolts (F2), iron pieces (F3), etc. Because of its good cloudiness, the feed material coming from the upper side rolls over iron (F0) by the force that is hit.

Then, the magnetic force is soared when the step portion, that is, the boundary between the iron adsorption surface 422 and the circular hardware adsorption surface 424, so that the magnetic force is soared, which is hidden under the stairs while being pulled to the inside of the step, that is, the circular hardware adsorption surface 424. As the magnetic force is inversely proportional to the distance squared, the magnetic force is rapidly increased because the distance from the magnet 400 is much shorter than that of the iron adsorption surface 422, and thus the magnetic force is rapidly fixed. In addition, it is also stepped, so there is little interference with the feed material, so that it can maintain a more strongly adsorbed state.

In particular, since the distance from the magnet 400 when there is a circular iron on the powdered iron powder F0 is increased by the thickness of the iron powder F0, the circular iron adsorption surface without iron powder F0 is compared with the distance at that time. The distance to the magnet 400 at 424 has a significant difference, and since the magnetic force is inversely proportional to the square of these distances, the rapidly rising magnetic force is so strongly adsorbed that the circular hardware is not easily rolled down.

In addition, since the circular hardware is located under a stepped step, the effect is even higher since the feed material does not interfere with them even if the feed material flows down.

Through this process, when the separation of hardware is completed, the supply of feedstock is stopped, and the equipment reaches idle time to supply other types of feedstock, the feedstock is not supplied at this time, so the gate cylinder is operated by operating the opening / closing cylinder 340. 420 and the magnet housing 320 are opened.

Then, as shown in FIG. 5, the magnet housing 320 is opened to the maximum, and at the same time, the gate 420 from which the external force is removed is rotated counterclockwise by its own weight, and the rotation is stopped by the hinge at the point where the magnet housing 320 is erected. At the same time, since the magnetic force applied to the gate 420 is lost, iron F0 attached to the front surface of the gate 420, that is, the iron adsorption surface 422, and the bearing ball F1 attached to the circular hardware adsorption surface 424. ), The bolts (F2), the circular hardware such as the iron piece (F3) is to be stored in the tray 500 while falling directly below the gate (420).

Afterwards, the worker can remove and process only the tray 500 to easily and precisely and completely remove and remove the irons mixed into the feed material.

When the iron separation and removal work is completed, the opening and closing cylinder 340 is operated again to seal the cutout 310 so that subsequent work may be performed again.
