Description

  The present invention relates to a grizzly feeder that sifts industrial waste such as slag so that it can be used as an industrial raw material, and more specifically, a mobile grizzly feeder that can satisfy the specifications of a vehicle that can run on a plant premises or on public roads. It is about cars.

  The present applicant has already been able to sieve the sieved articles at the accumulation site, etc., and can move flexibly according to the relationship between the accumulation position of the sieved articles at the site and the discharge position of the sieved products. For different types of products (see Patent Document 1) and objects to be crushed can be crushed in the accumulation area, etc., and can flexibly respond to the relationship between the accumulation position of the objects to be crushed and the discharge position of the crushed products Has been proposed (see Patent Document 2).

  For example, in a steelmaking plant, coke and ore as raw materials are sieved, large raw materials are crushed by a crusher, further sieved, and the raw materials are supplied to a blast furnace. On the other hand, pig iron is obtained from the blast furnace, and oxides such as silicon, aluminum and calcium in the iron ore are discharged as blast furnace slag. In addition, when performing hot metal desulfurization treatment, desiliconization treatment, and dephosphorization hot metal pretreatment before refining pig iron into the converter to obtain steel, desulfurization slag, desiliconization slag, Phosphorus slag is discharged.

  The diameter of the landfill material used for landfill is, for example, 25 mm or less, and the diameter of the landfill material is determined at present, so that it has become impossible to freely reclaim old construction waste and industrial waste.

  Also, at present, large plants such as steel manufacturing plants have already started to review industrial waste as one of the resources instead of discarding industrial waste to protect the natural environment. Therefore, the above-mentioned blast furnace slag, dephosphorization slag, desiliconization slag, and desulfurization slag are also required to be highly utilized as resources.

  The raw material of the plant has already been sieved to a certain size before being transported to the plant, and the above-mentioned mobile sieving device and multipurpose mobile crushing work vehicle are mounted on the accumulation site in the plant, It is possible to screen to a desired size and crush some. However, wastes that have been discarded in the past vary depending on the discharge process and the like.

For example, the above-mentioned blast furnace slag is a glassy sand-like substance because silicic acid mainly derived from iron ore is once melted and rapidly cooled in the blast furnace. Desiliconized slag is made of CaO-FeO-SiO2 slag by adding iron oxides such as mill scale and sintered ore into the hot metal. The dephosphorization slag is discharged after a dephosphorizing agent mixed with lime, iron oxide, fluorite, etc. is blown into the hot metal together with gas, and the phosphorus in the hot metal is transferred to the slag phase. The desulfurization slag is a slag that emerges by blowing a desulfurization agent such as CaO, Na ₂ CO ₃ , CaC ₂ , or Mg into the hot metal.

  Each slag floating on the hot metal is separated from the hot metal by slag scraping and cooled with water or the like. Scraping not only slag but also the surface of hot metal to produce high quality steel. For this reason, the slag still contains sufficient iron, and it was necessary to separate it.

  As described above, dephosphorization slag, desiliconization slag, and desulfurization slag other than blast furnace slag that becomes like fine sand are sized from over 50 cm to sandy depending on the degree of slag scraping. Is a city. Moreover, even if it is the same slag, the part which contains many irons is hard to crush, and the part which does not contain much iron is easily crushed.

In order to screen and crush such slag, many conventional sieving sites assemble grizzly feeders, supply industrial raw materials to the tilted grizzly bar screens, and slide down the grizzly bars. Sieving is performed between them. That is, the industrial raw material larger than between the grizzly bars slides down the inclined surface, and the small industrial raw material falls into the grizzly feeder from between the bars. A belt conveyor is installed from the inside to the outside of the grizzly feeder to convey the screened industrial raw materials to the outside.

  Since the conventional grizzly feeder is installed at the sieving place, it is necessary to have a dedicated grizzly feeder for the specific sieving material as described above, and a large permanent space is required for the installation place and the management place. is there. In addition, the conventional grizzly feeder has a fixed positional relationship between the input position of the sieved material and the discharge position of the sieved material, and the positional relationship between the raw material accumulation site and the screened storage site at the work site. On the other hand, there has been a problem that the optimum work position cannot always be taken.

  Furthermore, in the conventional sieving operation with a grizzly feeder, if the sieving material contains fine items, the sieving material is loaded when loading the sieving material on a truck or the like at the source (production area, waste land, etc.). Scatters and generates dust. Further, when a truck loaded with a sieved article travels on a road such as a public road and transports it to a sieved place, the sieved article falls or scatters. Further, when the sieved material is unloaded and sieved, the sieved material is scattered and dust is generated. Lastly, when sieving materials sorted according to size required are loaded on trucks and transported to the next treatment plant, the sieving materials are scattered to generate dust and travel on roads such as public roads. Even when transported to a sieving place, the sieving material falls or scatters.

  In addition, if a belt conveyor is installed inside the grizzly feeder to transport the material that has been sieved out of the grizzly feeder, the belt may be damaged because some of them have heavy specific gravity as described above. was there.

  Furthermore, when various slags are screened at an ironmaking plant, the iron content in the slag is different, resulting in differences in ease of crushing, as well as completely different weights and hardness even for the same size. Therefore, the strength of the grizzly feeder is required to be compatible with everything from hard and heavy to fragile and light.

  The present invention, for example, can go to an accumulation place where slag such as blast furnace slag, dephosphorization slag, desiliconization slag, desulfurization slag, etc. needs to be collected and efficiently screened as needed. The number of loading and unloading operations for transferring the sieved material can be reduced, dust generation can be reduced, and the position of the collected material in the field and the takeout position of the sieved product The purpose is to obtain a multi-purpose mobile grizzly feeder vehicle that can flexibly handle the relationship.

  The present invention can reduce the number of times of loading and unloading for transferring the material to be sieved, and can reduce the generation of dust. In addition, it is possible to go to the production area, accumulation area, etc., and efficiently sort the sieved articles as needed, and flexibly to the positional relationship between the collection position of the sieved articles and the extraction position of the sieved products in the field Yes. Furthermore, even when sieving industrial materials having a high specific gravity, there are effects such as little damage to the belt conveyor that conveys the material to be sieved and high durability.

  In the present invention, a grizzly feeder is mounted on a travelable vehicle chassis, and is a mobile grizzly feeder vehicle that feeds the sieved material to the rear of the vehicle via a conveyor, and is installed immediately below the grizzly feeder. A hopper portion that collects the sieved articles that have fallen between the grizzly feeders, and a sieved article that is disposed from the outlet of the hopper portion toward the conveyor carry-in port positioned on the rear side of the vehicle chassis and discharged from the hopper. And a feeder unit for feeding to the conveyor carry-in port.

  As a result, a grizzly feeder is mounted on a travelable vehicle chassis, and the sieved articles to be sieved are supplied to the conveyor, so that the articles to be sieved that require sieving work are accumulated. Since the sieving operation can be performed while going out, the number of loading and unloading operations for transferring the material to be sieved can be reduced, and the generation of dust can be reduced. In addition, it is possible to flexibly cope with the positional relationship between the accumulation position of the sieved material and the extraction position of the sieved product at the site. In addition, the material to be sieved that has fallen between the grizzly feeders does not fall directly on the belt conveyor, but falls on the feeder part and is gradually fed out to the conveyor by the feeder part, so that the industrial raw material having a high specific gravity is sieved. Even in this case, there is an advantage that the belt conveyor for conveying the material to be sieved is less damaged.

  The mobile grizzly feeder car of the present invention may or may not be provided with a belt conveyor in the vehicle chassis itself. When the belt conveyor is not installed, the length of the vehicle chassis only needs to be the length of the grizzly feeder. The length of the vehicle chassis should be 0.5 to 1.5 times the length of the vehicle. Therefore, it is preferable to install a belt conveyor in terms of effective use of the vehicle. In addition, you may make it the belt conveyor installed bend down, fold, or remove | eliminate during driving | running | working and mount in the chassis side.

  As the grizzly feeder of the present invention, the grizzly bar itself may be sieved while conveying the material to be sieved by vibration. It is more advantageous in terms of maintenance and the like to use those arranged in a substantially parallel shape with the lower side slightly widened. In addition, what is necessary is just to change the space | interval of a grizzly bar according to the magnitude | size of the object to be sieved. In order to change, each grizzly bar may be shifted little by little. Good.

  Also, for each inclination of the grizzly bar, the lower end portion may be moved up and down by hydraulic pressure or the like so as to change the inclination angle according to the object to be sieved. You may make it produce the frame | frame of a bar and reload this according to a to-be-sieved thing.

  The outlet of the hopper portion and the feeder portion of the present invention are preferably arranged in a biased manner on the lower side of the grizzly bar having a vehicle chassis width. In other words, the grizzly feeder is arranged with the axes of a number of grizzly bars tilted in the direction of the axle of the vehicle chassis. Is reduced.

  A large number of grizzly bars arranged in a substantially parallel shape, which are inclined in the direction of the axle of the vehicle chassis and slightly expanded on the lower side in the present invention, are formed of hard wires against the object to be sieved. As a preferred embodiment, waste can be effectively used by using railroad rails, more preferably railroad rails of 50 kg / m or more. Moreover, as another preferable aspect, what welded the wire along the axis on the upper surface side of the rail of a railroad is used. As a result, the material to be sieved placed on the upper surface of the rail is easily dropped from the upper surface of the rail, and there is an advantage that the material is easily screened.

FIG. 5 is a left side view of FIG. 6 is a front view of the grizzly feeder of FIG. 1, and FIG. 7 is a right side view of FIG. 8 is a front view of the vehicle chassis of FIG. 1, and FIG. 9 is a plan view of FIG.

  As shown in FIGS. 1 to 5, the mobile grizzly feeder vehicle 10 of this embodiment uses a semi-trailer 11 that is towed by a towing vehicle such as a tractor (not shown) as a vehicle chassis 11. In particular, a low-floor semi-trailer or a medium-low floor semi-trailer with a low trailer floor surface is suitable. A grizzly feeder 20 is mounted in the vicinity of the rise where a kingpin portion that engages with a coupler of a tractor in front of the vehicle chassis 11 is installed. A conveyor 30 is installed so as to incline from the lower side of the grizzly feeder 20 toward the rear upper side of the vehicle chassis.

  Jacks 15 are provided on both the front, rear, left and right sides of the vehicle chassis 11. These jacks 15 are reduced during traveling, and are extended to support the full load of the vehicle in order to maintain the horizontal stability of the vehicle body during work. These jacks 15 may be manually operated mechanical type or hydraulic type, and are preferably configured such that each can be adjusted independently.

  As shown in FIGS. 6 and 7, the grizzly feeder 20 is arranged by tilting the axes of a number of grizzly bars 21 in the direction of the axle (width direction) of the vehicle chassis 11. The sieving is carried by a wheel loader, a hydraulic excavator or the like from the side of the vehicle chassis 11 and from the inclined upper side of the grizzly bar 21 to the inclined surface of the grizzly bar 21. It is sieved while sliding in the lower slope direction. The large sieving material falls from below the grizzly bar 21 to the side of the vehicle chassis 11, and the small sieving material falls out of the gap between the grizzly bars 21.

  The large number of grizzly bars 21 are arranged in a substantially parallel shape with the lower side slightly widened, and are caught between the grizzly bars 21 when the object to be sieved is screened while sliding to the side of the vehicle from the upper part of the slope. It prevents that. The grizzly bar 21 is mounted with rails of 50 kg / m or higher, preferably rails of 60 kg / m used in Shinkansen and the like, with the flat bottom portion as the upper surface. A wire rod is welded to the upper surface of the grizzly bar 21 along the axis. As a result, when the object to be sieved is sieved while sliding to the side of the vehicle, it becomes easy to fall between the grizzly bars 21 and the sieving efficiency is improved.

  In addition, since the object to be sieved is conveyed from the upper slope side of the grizzly bar 21 by a wheel loader or a hydraulic excavator, the height of the uppermost slope of the grizzly bar 21 from the road surface is about 5 m. On the side of the side, a slope may be formed to meet a small wheel loader.

  Below the grizzly bar 21, a hopper portion is installed to prevent the sieved material screened at a high position from falling directly on the floor surface of the vehicle chassis 11. As the hopper portion, a first inclined plate 22 is arranged from the inclined upper side wall surface of the grizzly bar 21, and a second inclined plate 23 is arranged from the inclined lower side wall surface. The first inclined plate 22 is extended to the top of the sliding feeder 25 as a feeder portion arranged to be deviated to the lower side of the grizzly bar having the width of the vehicle chassis 11. A second inclined plate 23 is also arranged on the lower side of the grizzly bar 21 up to the sliding feeder 25.

  As shown in FIGS. 8 and 9, the sliding feeder 25 is arranged to be inclined downward toward the subsequent conveyor 30. Therefore, the guide plates 26 and 27 suspended from the end edges of the first and second inclined plates 22 and 23 to the side of the sliding feeder 25 also have end edges inclined along the sliding feeder 25. The material to be sieved sent by sliding back and forth of the sliding feeder 25 is transported by the belt conveyor 30 and transported to the subsequent stacking place. As described above, the material to be sieved once falls on the sliding feeder 25 and is gradually sent out to the conveyor 30 by the sliding feeder 25. There is an advantage that the belt conveyor 30 to be conveyed is less damaged.

  In addition, the inclination of the belt conveyor 30 is arranged so that the inclination can be lowered by the hydraulic device 31 so that the inclination can be reduced during traveling on a public road.

  As described above, the mobile grizzly feeder vehicle 10 according to the present invention can go to the generation source (production area, waste land, etc.) and screen the material to be screened as compared with the conventional fixed type grizzly feeder car. The number of loading and unloading operations for transferring the material to be sieved can be reduced, and the generation of dust can be reduced. In addition, it is possible to go to the production area, accumulation area, etc., and efficiently screen the material to be sieved as needed, flexibly depending on the positional relationship between the accumulation position of the material to be sieved and the extraction position of the sieved product at the site. Yes. Furthermore, even when sieving industrial raw materials having a high specific gravity, the belt conveyor that conveys the material to be sieved is less damaged and has been devised to increase durability.
