Description

TECHNICAL FIELD

[0001] The present application relates to the field of steelmaking, in particular to a high-efficiency nickel-iron particle classifying device. BACKGROUND

[0002] Nickel-iron particles are an important raw material for stainless steel smelting, mainly produced in Southeast Asian countries such as Indonesia, and mainly composed of nickel with a content of 15% to 55%. After purchasing nickel-iron particles to the factory, it needs to be detected for nickel content and harmful elements. Generally, it is delivered in ton bags by container or flatbed truck. We detect it by sampling and detecting according to the furnace batch number. For example, 20 tons for one furnace batch number, if one ton per bag, there are 20 bags, and 1 kg of sample is taken from each bag in the 20 bags, so 20 kg of sample for one furnace batch number, and finally only 1 kg of sample is needed for testing. Here, the 20 kg of sample needs to be classified, and after uniform classification by the classification device, it can be taken for testing. The existing market classification device blindly pursues multi-function and excessive classification uniformity, resulting in complex equipment structure, large equipment size, and heavy weight. It can only be placed at a fixed point, and then the sample is moved to the fixed point for classification. It cannot be directly moved to each storage area for flexible movement and on-site classification in the storage area. This will greatly increase the trouble at work, and it needs to be repeated. The original material is placed in multiple positions and multiple points in the storage area, and the appropriate amount of heavy material is moved to the point where the classification device is placed for classification, and then the non-sample material is moved back to the original storage area, greatly increasing the labor intensity. The disc classifier disclosed in the application number "CN201620556339.4" includes a box, a feed inlet is arranged above the box, a pressure cone, a scraper, a mixing disc, a mixing wall, a classification disc, a classification arm, a classification port, and a driving mechanism are arranged in the box. When the sample enters from the feed inlet, it is uniformly and smoothly dropped into the middle area of the classification disc under the action of the pressure cone, the scraper, the mixing disc, and the mixing wall, and then it is uniformly dropped along the periphery of the classification disc under the drive of the classification arm, and it is dropped into the corresponding classification port to achieve uniform classification. Its structure is complex, the processing cost is high, the size is large, and it is not suitable for moving and collecting samples from few points. And for the classification of nickel-iron particles, it does not need to be classified as high as other materials in the field. And the existing classification equipment directly separates the material into two or circular four or five groups after pouring once. The sample obtained by pouring and classifying comes from few points in the volume of the original material, which may cause more points in the original material pile to be collected even after repeated classification, resulting in poor classification effect. Therefore, it is necessary for the applicant to design a simple and sufficient classification device with good classification effect and convenient movement. SUMMARY

[0033] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be described in further detail below. The present application will be further described below with reference to the accompanying drawings.

[0034] Example one:

[0035] A high-efficiency nickel-iron particle classifying device, comprising a main hopper 1, a classifying groove 2 and a collecting groove 3, the main hopper is in a strip shape, the classifying groove is arranged at the bottom of the main hopper, there are at least ten classifying grooves arranged in sequence along the length direction of the main hopper, the lower part of the classifying groove is provided with a discharge port 21, and the two sides of the main hopper are respectively provided with a collecting groove for receiving the particles falling from the discharge port, and the discharge ports of adjacent classifying grooves are respectively arranged towards the collecting grooves on the two sides.

[0036] The bottom of the main hopper is provided with a long groove along the length direction thereof, the classifying grooves are arranged in sequence on the long groove, the adjacent classifying grooves are separated by a partition plate 24, the groove bottom plate of the classifying groove is an inclined guide plate 22, and the inclination directions of the guide plates of adjacent classifying grooves are opposite. The guide plates inclined in opposite directions can guide the material in each groove into the collecting groove.

[0037] In this embodiment, 12 to 20 aggregate tanks or even more are arranged in sequence, and if a bag of raw material is poured into the main hopper, the divided material can be evenly collected from 12-20 points, thereby greatly improving the uniformity of the distribution of the raw material sampling, which is more representative than the traditional several points. Moreover, the aggregate tanks of the present application are arranged in a row rather than a circular ring, further ensuring the balance of multi-point sampling. In use, the samples taken by multiple sampling can be mixed and then poured into the main hopper, and then alternately divided into two aggregate tanks after sampling through the twelve aggregate tanks, so that the first multi-point sampling is evenly divided into two sides for the first 1 / 2 division, and then the samples in one side of the aggregate tank are removed, and only the samples in the other side of the aggregate tank are taken and poured into the main hopper for sampling through the twelve points and then evenly divided into the aggregate tank, so that the sampling and division are performed to 1 / 4, and so on, until the required sampling is obtained, so that the sampling and division are performed to the twelve points each time, greatly improving the uniformity of the sampling. Moreover, the device structure of the present application is simple, and the traditional complex structure is changed, so that the staff can conveniently hold the device and place it in the raw material stacking area for on-site sampling at any time and anywhere, the operation is very convenient, and the uniformity of the sampling is much better than that of the existing complex division equipment.

[0038] Embodiment two:

[0039] The difference between the above embodiment and the present application is that a baffle 23 is arranged above the discharge port outside the main hopper, and the baffle is connected with the side groove wall of the division tank on both sides and connected with the outer surface of the main hopper on the top. The device structure of the present application is simple, and the samples divided by the guide plate fall directly into the aggregate tank downward and outward, and due to the self-weight of the samples, they may spread out of the aggregate tank, so the baffle is arranged to ensure that the samples are collected into the narrow aggregate tank, facilitating the control of the samples.

[0040] Embodiment three:

[0041] The difference between the above embodiment is that each of the division slots corresponds to a division unit 02, the division unit includes two symmetrical right-angled triangular panels 201 and a rectangular connecting plate 202 connected between the panels, the division unit is arranged from wide to narrow, and the top is open and connected with the long slot, the right-angled corner of the panel is arranged away from the center of the long slot, a notch is formed at the outside of the lower end of the division unit to form a discharging port, and a plurality of division units are arranged in reverse order. The width of the top opening of the division unit is greater than the width of the long slot. Each of the above division units corresponds to a triangular barrel with an opening at the top, and the direction of the adjacent division units is opposite. After the plurality of division units are arranged alternately, a plurality of division slots are formed in a straight line. The structure is simple, easy to assemble, and because the width of the main hopper long slot is less than the width of the top opening of the division unit, the sample can be dispersed into the large opening slot at the top of the division unit cavity as soon as it falls from the long slot. On the one hand, the sample is not easy to be stuck in the long slot, thereby improving the division efficiency, and on the other hand, the device can be supported with sufficient width, thereby having sufficient structural strength and relatively stable gravity center, so as to ensure the stability of the light device during use, prevent the device from being tilted due to the random pouring of the sample, and improve the stability of the device.

[0042] Embodiment four:

[0043] The difference between the above embodiment is that the main hopper includes an inner hopper surface 12 arranged obliquely, an outer hopper surface 13 connected to the outside of the inner hopper surface, an inner end hopper surface 121 connected between two opposite inner hopper surfaces, and an outer end hopper surface 131 connected between two outer hopper surfaces. The lower end of the outer hopper surface is lower than the connecting plate outside the division unit, higher than the upper edge of the discharging port, and parallel and fixedly connected to the corresponding connecting plate. The lower end of the inner hopper surface is connected with the top opening of the division unit. The inner end hopper surface of the main hopper extends upward and outward to form a handle or a handle is arranged outside the outer end hopper surface, thereby facilitating the staff to lift the main hopper and shake the main hopper.

[0044] The outer hopper surface and the outer end hopper surface surround the top outer periphery of all the division units, the entire structure is simple in shape and high in strength, and is safe and convenient to move. The triangular cavity formed between the inner hopper surface and the outer hopper surface is communicated with the top of the division unit, so that the sample has a sufficient diffusion space for rapid diffusion after being poured and is not easy to be stuck. The connection of the outer hopper surface, the outer end hopper surface, the inner hopper surface, the inner end hopper surface and the plurality of division units from the outside to the middle top greatly improves the structural strength and stability of the device made of thin plates, and the device is not easy to be overturned. The independent frame-shaped division unit is definitely much stronger than the simple pure thin plate as a partition, and is more stable after being connected with the outer hopper surface, the outer end hopper surface, the inner hopper surface and the inner end hopper surface, and is not easy to be deformed.

[0045] Embodiment five:

[0046] The difference between the above embodiment and the present embodiment is that the inner and outer hopper surfaces, the inner and outer end hopper surfaces of the main hopper and the dividing units are all made of thin iron sheets, the abutting panels between adjacent dividing units form the partition plates, and the abutting panels between adjacent dividing units are bent from the integrally connected thin iron sheets, and the collecting chute 3 is also made of thin iron sheets. The entire frame of the present application is mainly made of thin iron sheets, and is cast from thick metal materials, so that the overall weight is relatively light, facilitating the moving and taking of the device at any time and any place, and the cost is low. Moreover, each part is mainly bent from a thin iron sheet, and is only welded at the end of the iron sheet, so that the processing is very convenient, and no mold is needed for casting, thereby saving the production cost. Moreover, the cooperation of the thin iron sheet and the specific structure design of the present application enables the device to be thin and light while having sufficient strength.

[0047] Embodiment six:

[0048] The difference between the above embodiment and the present embodiment is that the dividing device further comprises a support frame 5, the support frame comprises an upper support and a lower support, the upper support comprises a bottom support beam 51 and a group of side protection components 52 symmetrically connected to the bottom support beam, the bottom support beam is arranged at the bottom of the main hopper and is arranged along the length direction of the main hopper, and the side protection components are arranged at the side surface of the main hopper and are used for supporting the main hopper in cooperation with the bottom support beam. The bottom support beam and the side protection components made of thin metal rods as described above are used to surround and support the main hopper, so that the support strength of the main hopper can be ensured while the portability is ensured to facilitate the moving of the staff.

[0049] Embodiment seven:

[0050] The difference between the above embodiment and the present embodiment is that the guide plates in different inclined directions form an included angle 221 when viewed from the end of the main hopper, the bottom support beam is arranged in the included angle, the side protection component comprises a connecting rod segment 521 which is fixedly connected to the bottom support beam and is arranged obliquely upward, and a side rod segment 522 which is connected to the connecting rod segment, the connecting rod segment is arranged outside the end of the length direction of the main hopper, and the side rod segment is arranged outside the side surface of the main hopper and is fixedly connected or abuttingly connected to the outer surface of the main hopper. The side rod segment can be directly fixedly connected to the outer surface of the main hopper or can be tightly abuttingly and clampingly connected, and the design of the detachable clamping connection is convenient for disassembly and assembly. The included angle formed by the guide plates at the bottom of the main hopper is just suitable for the bottom support beam to be arranged at this position, so that the stability of the support of the bottom of the main hopper can be ensured in the case of extremely simple upper support.

[0051] Embodiment eight:

[0052] The difference between the above embodiment is that the angle between the two link segments at the same end is expandable by the elasticity of the material flexibility of the link segment itself or by the elasticity of the elastic component connected between the two, the main hopper can be clamped between the side guard components by overcoming the elasticity of the material flexibility of the link segment or the elasticity of the elastic component; the distance between the lower ends of the two opposite side discharge ports is smaller than the distance between the two side link segments when the main hopper is not clamped, and the main hopper has a corresponding embedding groove 11 on the outer surface of the main hopper. The link segment is a metal round rod, which can clamp the main hopper by spreading the link segment to the two sides when the main hopper is clamped, and of course the elastic component such as spring can be arranged between the link segments to clamp the main hopper and facilitate disassembly. The design of the support frame and the main hopper can be easily disassembled, which is convenient for carrying and disassembling, and can cope with complex scaling environment, and even can be used directly without using the support frame, as long as the two ends of the main hopper are lifted.

[0053] Embodiment nine:

[0054] The difference between the above embodiment is that the lower support frame includes a triangular end support part 53 connected to the outer end of the bottom support beam and a pulling part 54 connected between the end support part and the bottom support beam, and the lower end of the pulling part is connected to the center of symmetry of the bottom of the end support part.

[0055] The lower support frame of the present application is a simple structure of a rod-shaped ring frame, which has a light volume. Compared with the existing scaling device with a flat base, the above structure of the present application makes the requirement for the flatness of the ground surface low, and the carrying is light. The device of the present application can be applied to various scaling environments, and is particularly suitable for various material stacking workshops, and can be used even on the material pile.

[0056] Embodiment ten:

[0057] The difference between the above embodiment is that the end of the bottom support beam is sequentially connected to the top of the end support part, the bottom of the link segment and the top of the pulling part from outside to inside, and the three connected parts are arranged alternately, and the top of the pulling part is located at the bottom of the main hopper. Through the above structure, the entire end support part, link segment and pulling part are in a three-dimensional dimensional space, rather than in a plane, thereby greatly enhancing the strength of the entire support frame, and ensuring the support strength of the main hopper and the stability of the device placement during use under the premise of simple structure design.

[0058] The end support part is a hollow part formed by a metal strip, and the two ends of the end support part are bent downward to form support points 531. The entire support frame can be formed by bending and welding a metal strip, which is low in cost, light in weight, simple in structure, and convenient to place the end support part on uneven ground through the support points at the two ends instead of the entire bottom support strip. It can be applied to various complex environments, and is more practical.

[0059] Embodiment eleven:

[0060] The difference between the above embodiment and the present embodiment is that the size reduction device further comprises a movable discharging inverted hopper 6 and a hopper foot assembly 7 for erecting the inverted hopper, the hopper foot assembly comprises a floor-standing hopper foot, a hopper support erectable on the end edge of the main hopper, and a guide rail 73, the main hopper is provided with a hopper foot 71 on at least one outer side and a hopper support 72 on the other end, the guide rail is connected between the hopper foot and the hopper support, the main hopper is provided with a baffle plate 74 at least on the end close to the hopper foot, the baffle plate is located at the position of the bottom discharge port of the inverted hopper for plugging the discharge port, and the inverted hopper is arranged on the guide rail and can reciprocate above the main hopper along the guide rail.

[0061] When necessary or in order to further improve the size reduction effect, a movable inverted hopper can be erected on the upper end of the main hopper, and the inverted hopper is reciprocated above the main hopper to uniformly discharge the materials in the main hopper into the size reduction slots. The detachable hopper foot assembly can be erected on the main hopper, the lower end discharge port of the inverted hopper is pressed against the baffle plate to seal it, and at this time the discharge port of the inverted hopper is located on the outer side of the main hopper. When the worker finishes pouring the materials into the inverted hopper, the worker pulls the inverted hopper along the guide rail, and the discharge port is separated from the baffle plate to start discharging. The inverted hopper moves while uniformly discharging the materials into the main hopper, so that the materials in one hopper can be uniformly poured into the size reduction slots. The size reduction slots can be more than ten or even more, as long as the total length is not too long, and the sample can be automatically uniformly scattered and covered in all size reduction slots after being poured into the long main hopper at one time without using the inverted hopper.

[0062] Because the center of gravity of the inverted hopper is higher than that of the main hopper, the inverted hopper cannot be directly placed on the main hopper, otherwise the center of gravity of the whole main hopper will be raised, the stability requirement of the supporting legs will be increased, and the main hopper is prone to overturning. In order to reduce the structure of the equipment, ensure the stability of the center of gravity, and the convenience of optional use of the inverted hopper, the hopper leg assembly of the present application can be placed on the main hopper at one end and supported by the hopper supporting legs on the ground at the other end, or both ends can be the hopper supporting legs on the ground, but it cannot be directly placed on the main hopper at both ends. The initial state of the inverted hopper filled with materials is mainly supported by the hopper supporting legs, so as to ensure the relative stability of the main hopper and the inverted hopper, and the hopper supporting legs are located outside the main hopper and the inverted hopper, so as to ensure that the equipment is equivalent to adding an external supporting leg to improve the stability, and the light main hopper will not be tilted due to the excessive weight of the inverted hopper located at the end of the main hopper.

[0063] The hopper leg assembly can be selectively placed on the main hopper, and then the inverted hopper is placed on the hopper leg assembly for use.

[0064] Embodiment twelve:

[0065] The difference between the above embodiment is that one end of the material blocking plate is connected to the edge of the main hopper, the other end is connected to the support foot of the hopper, the material blocking plate is an inclined groove plate, and the inner end towards the center of the main hopper is lower than the outer end. A hook 76 is connected to the outer surface of the inverted hopper for hooking the top of the crosspiece 75 of the support foot of the hopper. Since the material blocking plate is mainly located on the outside of the main hopper, in order to prevent the material on the inverted hopper from leaking out of the gap between the discharge port and the material blocking plate, the material blocking plate is designed as a groove with blocking plates on both sides, and if the material blocking plate is a horizontal plate, it is likely that part of the granular sample will be missed on the inverted hopper after moving above the main hopper, and the staff needs to manually push the missed or leaked sample into the main hopper. The application uses an inclined material blocking plate to reduce the weight of the equipment while ensuring that the missed or leaked sample slides directly into the main hopper along the inclined surface without the need for secondary cleaning. Under normal circumstances, there will be no excessive missing or leakage, and only a small amount of material will be squeezed out of the discharge port. In addition, if the material blocking plate is horizontal and the discharge port is horizontal, the fit between the two is high, and once there is a gap, it is difficult to repair. The inclined material blocking plate can reduce the gap between the discharge port of the inverted hopper and the material blocking plate. As long as the inverted hopper is pushed towards the material blocking plate, the corresponding inclined discharge port can be tightly fitted on the material blocking plate, and then the inverted hopper can be fixed. In addition, due to the inclination of the material blocking plate, the sample in the inverted hopper may be pushed towards the main hopper by the gravity of the sample, causing the bottom of the inverted hopper to move and leak before the sample is completely poured into the inverted hopper. To overcome the inward pushing force of the inclined material blocking plate, the application also provides a hook, and a crosspiece is designed on the top of the support foot. The hook of the inverted hopper can hook the crosspiece, thereby ensuring the stability of the inverted hopper when it does not move. The hook can be hinged to the inverted hopper or can be moved up and down to be clamped to the crosspiece. An inclined abutting surface can be provided between the hook and the crosspiece, so that the discharge port at the bottom of the inverted hopper can be tightly fitted on the material blocking plate.

[0066] Embodiment thirteen:

[0067] The difference between the above embodiment is that the inverted hopper is provided with a bracket groove 61 on both sides for cooperation with the guide rail, and at least two pulleys 62 are arranged in each bracket groove. The surface of the pulley is arranged on the guide rail. The movement of the inverted hopper of the application can be achieved by the above simple and convenient arrangement and cooperation with the guide rail, thereby simplifying the structure, reducing the cost, and facilitating disassembly and assembly. Of course, other ways of moving the inverted hopper above the main hopper are not excluded.
