Description

Technical Field

[0001] The utility model relates to the technical field of closed material warehouses, in particular to a closed material warehouse adopting a full-door material taking device. Background Art

[0002] Against the backdrop of increasingly stringent environmental protection requirements for the steel industry, closed silos have been adopted by most steel companies, and the form of closed silos is also being continuously optimized. The selection and layout of the stacking and reclaiming device has a great impact on the investment cost and operating efficiency of the closed silo. Most of the existing closed silos have a longitudinal partition wall in the middle to support the upper unloading platform, and semi-gantry scraper reclaimers are set on both sides of the longitudinal partition wall to take the materials to the discharge conveyor. Since the accumulation of materials generates lateral pressure on the partition wall, higher requirements are placed on the mechanical properties of the partition wall, and the setting of the partition wall and the unloading platform increases the amount of civil engineering and construction costs. In addition, the use of a semi-gantry scraper reclaimer has limited working space, and there will be a large dead material area, resulting in incomplete material reclaiming.

[0003] Prior art 1: A closed storage warehouse of a C-type dust suppression material yard, with a longitudinal partition wall arranged along the longitudinal direction of the material yard, a stacking platform arranged on the top of the longitudinal partition wall, and a stacking machine arranged on the stacking platform; ground mobile reclaiming equipment, i.e., a semi-gantry scraper reclaimer, is arranged on both sides of the longitudinal partition wall, and a material output conveyor is arranged under the reclaiming equipment.

[0004] Disadvantage 1: A longitudinal partition wall is set in the middle of the material yard to support the upper unloading platform, which requires a large amount of civil engineering and high investment cost;

[0005] Disadvantage 2: Semi-gantry scraper reclaimers are set on both sides of the longitudinal partition wall. There is a large dead material area when reclaiming, which may cause incomplete reclaiming.

[0006] Disadvantage 3: The semi-gantry scraper reclaimer on one side can only take materials from the material grid on the same side, and cannot take materials from the material grid on the other side.

[0007] Prior art 2: A closed material yard using a full-door scraper reclaimer, which includes a storage yard, a feeding device, a material output conveyor, a scraper reclaimer, a storage shed, a material input conveyor and a discharge device. The storage shed is provided with a top platform for the installation of the material input conveyor and the movement of the discharge device. The scraper reclaimer is a full-door structure, mainly composed of a gantry, a scraper mechanism, a telescopic mechanism, and a connecting rod. A feeding device and a material output conveyor connected to the feeding device are arranged in order from top to bottom below the discharge port in the middle of the bottom of the storage yard. Problems:

[0008] Disadvantage 1: Since the material output conveyor is located underground in the middle of the material yard, the civil engineering of the underground part needs to be considered when building the material yard, which will increase the amount of civil engineering and construction costs;

[0009] Disadvantage 2: When the material pile is output, it needs to enter the output conveyor through a feeding device. When the longitudinal length of the material yard is large, multiple feeding devices need to be set up, and the equipment cost is high;

[0010] Disadvantage 3: The material yard is enclosed with a portal steel frame structure, and when applied to a large material yard, a column is required in the middle, so this type of material yard is only suitable for small material yards.

[0011] Existing technology three: a truss-type long environmentally friendly material yard, which mainly includes a closed storage shed and a stacking device, a material taking device, a stacking device running track, a material taking device running track, a material input conveyor, a material output conveyor, a discharge platform and a storage yard, the storage yard is provided with a plurality of transverse partition walls along its longitudinal intervals, the discharge platform is a truss structure, and the discharge platform is supported by the transverse partition walls at both ends. Problems:

[0012] Disadvantage 1: The unloading platform is a truss structure erected on the transverse partition walls at both ends of the material yard, and the middle unloading platform has no supporting structure, so the transverse partition walls at both ends bear a large load, and high requirements are placed on the transverse partition walls at both ends;

[0013] Disadvantage 2: When the length of the unloading platform is too long, the truss structure cannot support the entire unloading platform, so the material yard described in this patent is only suitable for small material yards.

[0014] Disadvantage three: The closed storage shed is fully enclosed with wall skin, and the structural form is not mentioned. If it is an ordinary portal steel frame structure, when the span of the material yard is large, columns are required in the middle of the material yard to support the steel structure closure, which will affect the operation of the material taking device.

[0015] Therefore, the inventor, relying on his many years of experience and practice in related industries, proposes a closed material warehouse using a full-door material taking device to overcome the defects of the prior art. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0045] like Figure 1 , Figure 2As shown, the utility model provides a closed material warehouse adopting a full-door material taking device, including a mesh shell closed structure 1, a material input system 2, a full-door scraper material taking device 3 and a material output system 4, the mesh shell closed structure 1 constitutes a material field space (referred to as the material field); the internal top end of the mesh shell closed structure 1 is suspended with a material input system 2 for conveying materials to the material field space; the full-door scraper material taking device 3 includes a full-door frame structure 31 which is arranged along the transverse direction of the material field space and can move along the longitudinal direction of the material field space, and two scraper mechanisms which are arranged along the transverse direction of the material field space and can swing in a linked manner in a vertical plane are arranged in the full-door frame structure 31, and the adjacent ends of the two scraper mechanisms are hingedly connected; the material output system 4 is arranged on one side of the full-door frame structure 31, and the two scraper mechanisms scrape the materials of each cross section in the material field space as a whole and transport them to the material output system 4, and the materials are transported out of the material field space by the material output system 4 and then transported to the demand unit.

[0046] The two scraper mechanisms work in conjunction, so the material can cover the entire width of the material strip (the overall width of each cross-section of the material field space).

[0047] In the prior art, when a semi-gantry scraper reclaimer is used, a longitudinal partition wall needs to be set in the middle of the material yard, one is to provide a track and support for the movement of the semi-gantry scraper reclaimer, and the other is to support the unloading platform on the upper part of the longitudinal partition wall. This will lead to a large amount of civil engineering work when building the material yard, and the space utilization rate of the material yard is reduced. In addition, due to a certain gap between the partition wall and the reclaimer, a large dead material area is formed, which will affect the reclaiming operation.

[0048] In order to solve the material output problem and ensure that materials of the same material strip can be transported out from one output conveyor, the existing full-gantry scraper reclaimer sets the output conveyor underground in the middle of the material yard, and sends the materials to the output conveyor through the scraper reclaimer and feeder. This layout will not only increase the amount of civil engineering, but also require increased equipment investment, which greatly increases the cost.

[0049] The utility model adopts a full-door material taking device for material taking operation, and two scraper mechanisms work in conjunction to cover the entire material strip width of each cross section, reduce the dead material area during material taking, and improve the efficiency of the material taking device;

[0050] The material input system is suspended at the inner top of the grid shell closed structure 1, and the grid shell closed structure provides support. There is no need to set up a longitudinal partition wall to support the unloading platform, there is no need to set up columns to support the steel structure closure, and there is no need to set up a material output system underground in the middle of the material yard. It can effectively reduce the amount of civil engineering required to build a material yard, reduce construction costs, increase the material yard stacking area, and improve the space utilization rate of the material yard. It is suitable for material yards of various sizes including large material yards.

[0051] Furthermore, the full gantry structure 31 needs to move longitudinally along the material yard space, and its movement can rely on the running track 33 or the roller structure.

[0052] like Figure 1 As shown, in a specific embodiment, a running track 33 is arranged in the lattice shell closed structure 1 along the longitudinal direction of the material field space, and the full gantry structure 31 can drive each scraper mechanism to move along the running track 33 to change the material taking position.

[0053] The full gantry structure 31 stands on the running track 33 and moves on the running track 33 during operation. The scraper mechanism can scrape materials at different positions.

[0054] In another specific embodiment, a gantry roller capable of driving the full gantry structure to move longitudinally along the material yard space is disposed at the bottom end of the full gantry structure.

[0055] Further, if Figure 1 , Figure 2 As shown, two scraper mechanisms are set as the first scraper mechanism 321 and the second scraper mechanism 322. A first telescopic mechanism 341 for driving the first scraper mechanism 321 to swing is set on one side of the full gantry structure 31, and a second telescopic mechanism 342 for driving the second scraper mechanism 322 to swing is set on the other side of the full gantry structure 31. The first scraper mechanism 321 and the second scraper mechanism 322 can scrape the material of the entire cross section (that is, the material of the entire strip width). The state of the first scraper mechanism 321 and the second scraper mechanism 322 when they swing to the lowest position is shown in FIG. Figure 1 As shown, the state when the first scraper mechanism 321 and the second scraper mechanism 322 swing to the highest position is as shown in FIG. Figure 2 shown.

[0056] Further, if Figure 1 , Figure 2 As shown, the adjacent ends of the first scraper mechanism 321 and the second scraper mechanism 322 are hinged by a connecting rod 35.

[0057] The scraper mechanisms are connected together by a connecting rod 35. When taking materials, the scraper mechanisms on both sides are controlled by the telescopic mechanism to work simultaneously (swing and move). The scraper mechanisms can cover the entire width of the material strip and perform material taking operations on the entire cross section of the material strip.

[0058] Further, if Figure 1 , Figure 2 As shown, the material input system 2 includes a feeding belt conveyor 21 and a discharge vehicle 22 mounted on the top of the inner part of the lattice shell closed structure 1. The feeding belt conveyor 21 and the discharge vehicle 22 are mounted on the top of the inner part of the lattice shell closed structure 1 (under the steel structure roof), and are suspended above the material yard to transport the materials to the material yard for storage. The number of feeding belt conveyors 21 can be one or two, depending on specific needs.

[0059] Further, if Figure 1 , Figure 2 As shown, a discharge platform 23 is suspended at the top of the inner part of the lattice shell closed structure 1 , and a feeding belt conveyor 21 and a discharge vehicle 22 are arranged on the discharge platform 23 .

[0060] The feeding belt conveyor 21 and the unloading platform 23 are arranged at the inner top end (under the steel structure roof) of the grid shell closed structure 1, and the grid shell closed structure 1 (steel structure roof) provides support force.

[0061] Further, if Figure 1 , Figure 2 As shown, the material output system 4 includes a discharging belt conveyor 41 arranged on one side of the full gantry structure 31, and the discharging belt conveyor 41 receives the material scraped and transported by the conveying scraper mechanism. Specifically, the discharging belt conveyor 41 is arranged under the scraper mechanism on one side.

[0062] The two scraper mechanisms of the full-door scraper material taking device 3 are connected together, and the materials of the entire material strip section can be scraped to the discharging belt conveyor 41 on one side.

[0063] Furthermore, one or two full-door scraper reclaiming devices 3 are arranged in the material yard space, and each full-door scraper reclaiming device 3 is respectively matched with a discharging belt conveyor 41. That is, one set of full-door scraper reclaiming device 3 is equipped with one discharging belt conveyor 41, and one material yard can be equipped with two sets of full-door scraper reclaiming devices 3 and two discharging belt conveyors 41.

[0064] The material output system can also be arranged under the material field on one side of the full portal structure 31 .

[0065] Furthermore, the lattice shell closed structure 1 comprises a lattice steel structure frame, on which a wall structure is sealed.

[0066] The closed structure of the material warehouse is a lattice shell structure, which can effectively close the entire material yard and can be applied to the working conditions of large material yards;

[0067] The material input system 2 is arranged at the inner top of the gridshell closed structure 1 (under the steel structure roof), and the roof gridshell structure provides support force, which can provide support force for the unloading platform 23, and no pillars are required in the middle of the material yard to support the closed structure.

[0068] The utility model provides a closed material storage using a full-door material taking device. The use process is as follows:

[0069] The materials are transported to the internal stockpile of the material yard through the material input system 2. When the stored materials need to be taken, the full-gantry scraper material taking device 3 starts to work, and the full-gantry structure 31 moves to the cross section of the material to be taken, such as Figure 1As shown, the first telescopic mechanism 341 and the second telescopic mechanism 342 simultaneously drive the first scraper mechanism 321 and the second scraper mechanism 322 to swing and move to the scraping working position, and the first scraper mechanism 321 and the second scraper mechanism 322 transport the material to the material output system 4, and then transport it to the demand unit.

[0070] As described above, the closed material warehouse using the full-door material taking device of the utility model has the following beneficial effects:

[0071] The utility model adopts a full-door material taking device for material taking operation, and two scraper mechanisms work in conjunction to cover the entire material strip width of each cross section, reduce the dead material area during material taking, and improve the efficiency of the material taking device;

[0072] The material input system is suspended at the top of the inner part of the grid shell closed structure, and the grid shell closed structure provides support. There is no need to set up longitudinal partition walls to support the unloading platform, no need to set up columns to support the steel structure closure, and no need to set up a material output system underground in the middle of the material yard.
