Abstract

This utility model proposes a simplified C-type silo, comprising an enclosed shed and internal longitudinal and transverse partitions, feed lines, a steel structure grid, an discharge line, and a full-gantry scraper reclaimer. Feed lines are suspended on both sides of the lower part of the steel structure grid, and unloading vehicles are installed on these feed lines, allowing movement along the length of the longitudinal partitions. Multiple transverse partitions are located on both sides of the longitudinal partitions, creating multiple silo compartments. The full-gantry scraper reclaimer is positioned across the silo compartments and the discharge line. This simplified C-type silo, by replacing the central feed line in existing designs with feed lines on both sides, alters the cross-sectional shape of the material pile. This change in cross-sectional shape allows for a reduction in the height of the longitudinal and transverse partitions, significantly reducing the amount of concrete poured and thus lowering the silo's construction cost.

Description

Technical Field

[0001] This utility model relates to the field of material storage technology, and in particular to a simplified C-type material storage silo. Background Technology

[0002] Currently, in the mechanized raw material yards of steel enterprises, C-type silos are widely used to increase the storage capacity per unit area. Most of them are used for storing and transporting iron ore required by the sintering workshop or coking coal used by the coking workshop. C-type silos can meet the storage requirements of steel enterprises for a variety of materials.

[0003] The normal process flow for existing C-type silos is as follows: material arrival via belt conveyor → C-silo unloading car → C-silo storage in grid cells → scraper reclaimer → belt conveyor to the user's workshop. In existing C-type silos, the two unloading cars are located on either side of the top of the longitudinal partition wall, that is, in the middle of the enclosed shed, thus forming a C-shaped stacking section. This C-shaped stacking section requires a very high longitudinal partition wall, resulting in a very large amount of concrete pouring. The concrete construction cost accounts for 70% of the overall cost of the C-type silo. Therefore, although C-type silos have the advantage of high storage capacity per unit area, the large amount of concrete required leads to high construction costs, making them unsuitable as a priority for small and medium-sized steel enterprises. Utility Model Content

[0004] The main purpose of this utility model is to provide a C-type silo, which aims to reduce the construction cost of the C-type silo by reducing the amount of concrete.

[0005] To achieve the above objectives, this utility model provides a simplified C-type material silo, including an enclosed shed and internal longitudinal and transverse partitions, a feeding line, a steel structure grid frame, a discharging line, and a full-gantry scraper reclaimer. A feeding line is suspended on each of the two sides below the steel structure grid. A unloading car is installed on the two feeding lines and can move along the length of the longitudinal partition wall. Multiple transverse partition walls are set on both sides of the longitudinal partition wall to separate and form multiple material bins. The full-gantry scraper reclaimer is arranged across the material bins and the unloading line.

[0006] Preferably, the steel structure space frame includes an outer frame arranged along the shape of the enclosed material shed and multiple crossbeams arranged below the outer frame.

[0007] Preferably, the feed line is suspended below the crossbeam and fixedly connected to it.

[0008] Preferably, the distance between the centerline of the feed line along the length of the longitudinal partition wall and the center surface of the corresponding material bin is L1, and the distance between the centerline of the feed line along the length of the longitudinal partition wall and the outer surface of the corresponding material bin is L2, with L1:L2 being between 1:2 and 1:10.

[0009] Preferably, the feeding line includes a long cantilever unloading trolley fixed on a column. The long cantilever unloading trolley includes a belt conveyor arranged laterally. The belt conveyor rotates forward or backward to switch to unload material into the material bins on both sides. The length of the belt conveyor is L3, and the inner cross-sectional length of the enclosed material shed is L4. The ratio of L3 to L4 is between 1:2 and 1:10.

[0010] Preferably, the full gantry scraper reclaimer is a tail-shaped scraper reclaimer, and the full gantry scraper reclaimer uses a two-section scraper; the feeding line includes an external support frame suspended below and fixedly connected to the steel structure grid and a linear track installed inside the support frame, and the unloading car is located on the linear track and is movable relative to it.

[0011] Preferably, the steel structure grid includes an outer frame arranged along the shape of the enclosed material shed and multiple crossbeams arranged below the outer frame, with the feeding line suspended below the crossbeams.

[0012] Preferably, the steel structure grid also includes multiple columns located in the middle of the enclosed material shed, which support the middle of the crossbeam and are fixedly connected to it.

[0013] Preferably, the longitudinal partitions and transverse partitions are of equal height.

[0014] Preferably, when the discharge line is located on both sides of the enclosed shed, the longitudinal partition wall is located in the middle of the enclosed shed, the cross section of the transverse partition wall is a right trapezoid, the right angle of the trapezoid is flush with the longitudinal partition wall, and the bottom of the column is inserted between the two longitudinal partition walls.

[0015] Preferably, the longitudinal partition wall is configured as two layers, and the two longitudinal partition walls are connected by multiple support beams, with the columns fixed to the support beams.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] This utility model proposes a first embodiment of a simplified C-type material silo. (Refer to...) Figures 1 to 4 In this embodiment, a simplified C-type silo includes an enclosed shed 8 and internal longitudinal partitions 1, transverse partitions 2, a feeding line 3, a steel structure grid 4, a discharging line 5, and a full-gantry scraper reclaimer 6. A feeding line 3 is suspended on each of the two sides below the steel structure grid frame 4. A unloading car 7 is installed on the two feeding lines 3 and can move along the length of the longitudinal partition wall 1. Multiple transverse partition walls 2 are set on both sides of the length of the longitudinal partition wall 1 to form multiple material storage compartments. The full gantry scraper reclaimer 6 is arranged across the material storage compartments and the discharge line 5.

[0025] The enclosed material shed 8 is built on the outside of the steel structure frame 4, and the material of the enclosed material shed 8 is supported by the steel structure frame 4.

[0026] In this embodiment, the distance between the centerline of the feed line 3 along the length of the longitudinal partition wall 1 and the center surface of the corresponding material hopper is L1, and the distance between the centerline of the feed line 3 along the length of the longitudinal partition wall 1 and the outer surface of the corresponding material hopper is L2. The ratio of L1 to L2 is between 1:2 and 1:10. The center surface of the material hopper refers to its side surface near the middle of the enclosed shed 8, and the outer surface of the material hopper refers to its side surface near the side wall of the enclosed shed 8.

[0027] Specifically, the full-gantry scraper reclaimer 6 adopts a tail-end type scraper reclaimer. In order to reduce the height of the overall greenhouse steel structure frame 4, the full-gantry scraper reclaimer 6 uses a two-section scraper.

[0028] In this embodiment, the feeding line 3 includes an external support frame 31 suspended below and fixedly connected to the steel structure space frame 4, and a linear track 32 installed inside the support frame. The unloading trolley 7 is located on the linear track 32 and is movable relative to it. The external support frame 31 can be welded to the steel structure space frame 4.

[0029] Specifically, the steel structure space frame 4 includes an outer frame 41 arranged along the outer shape of the enclosed material shed 8 and multiple crossbeams 42 arranged below the outer frame 41. The feed line 3 is suspended below the multiple crossbeams 42 and fixedly connected to them. The outer frame 41 and the crossbeams 42 can be connected by welding or fasteners, and this utility model does not limit this. The multiple crossbeams 42 are evenly arranged along the length of the longitudinal partition wall 1.

[0030] In this embodiment, in conjunction with reference Figure 2 and Figure 3 The steel structure space frame 4 also includes multiple columns 43 located in the middle of the enclosed material shed 8. The columns 43 support and are fixedly connected to the middle of the crossbeam 42. By setting the columns 43 in the middle of the enclosed material shed 8, the span of the steel structure is reduced, which improves the structural stability on the one hand, and reduces the construction cost of the steel structure space frame 4 on the other.

[0031] Specifically, in this embodiment, referring to Figure 3 and Figure 4 The longitudinal partition wall 1 and the transverse partition wall 2 may have equal or unequal heights. In the prior art, because the two unloading trucks 7 are located on both sides of the top of the longitudinal partition wall 1, and the longitudinal partition wall 1 is located in the middle of the enclosed material shed 8, most of the weight of the material needs to rely on the longitudinal partition wall 1 to form a C-shaped material stacking section, which requires the longitudinal partition wall 1 to be very high. In this embodiment, because the two unloading trucks 7 are located on both sides of the enclosed material shed 8, the material stacking section is no longer C-shaped. Therefore, it is not necessary to have very high longitudinal partition walls 1 and transverse partition walls 2, which can greatly reduce the height of the longitudinal partition walls 1 and transverse partition walls 2. Compared with the longitudinal partition walls and transverse partition walls in the prior art, the height can be reduced to 5~10m, which can reduce the amount of concrete work and thus reduce the project cost.

[0032] In this embodiment, refer to Figure 3 When the discharge line 5 is located on both sides of the enclosed shed 8, the longitudinal partition wall 1 is located in the middle of the enclosed shed 8, and the cross section of the transverse partition wall 2 is a right-angled trapezoid, with the right-angled leg of the trapezoid flush with the longitudinal partition wall 1. The bottom of the column 43 is inserted into the interior of the longitudinal partition wall 1. The width of the longitudinal partition wall 1 is greater than the width of the column 43. That is to say, before pouring concrete, the column 43 is pre-embedded inside the longitudinal partition wall 1, and then the concrete is poured to form the structure, thereby improving the overall structural strength of this C-type silo.

[0033] Specifically, in this embodiment, a tail-shaped scraper reclaimer is used for material collection. In conjunction with the change in the shape of the transverse partition wall 2, the longitudinal low wall on the material discharge side of the grid is eliminated, thereby reducing the amount of concrete work in this part.

[0034] The cross section of the transverse partition wall 2 is trapezoidal, with the top and bottom surfaces of the trapezoid being horizontal. The right-angled legs of the right trapezoid are flush with the longitudinal partition wall 1. Using this structure, the thickness of the transverse partition wall 2 can be reduced, thereby reducing the amount of concrete work.

[0035] In this embodiment, there are two longitudinal partition walls 1, which are connected by multiple support beams, and the columns 43 are fixed to the support beams.

[0036] The loading and unloading process of this simplified C-type silo is as follows.

[0037] When materials are input, the unloading vehicle 7 moves on the feeding line 3, thereby unloading the materials on the unloading vehicle 7 into the designated material storage compartment.

[0038] When outputting materials, the full-gantry scraper reclaimer 6 picks up the materials through its reclaiming mechanism and finally places them on the conveyor belt on the discharge line 5. The conveyor belt then transports the materials to transport them out of the C-type silo.

[0039] The simplified C-type silo proposed in this embodiment has the following beneficial effects: 1. By changing the feed line 3 set in the middle of the existing technology to feed lines 3 set on both sides, the cross-sectional shape of the material pile can be changed. The change in the cross-sectional shape of the material pile can reduce the height of the longitudinal partition wall 1 and the transverse partition wall 2, thereby greatly reducing the amount of concrete poured and thus reducing the project cost. 2. By changing the tail structure of the material handling equipment, the longitudinal low wall on the discharge side can be eliminated; 3. The installation of two longitudinal partition walls 1 can significantly reduce the thickness of the longitudinal partition walls 1; 4. The setting of the central column 43 can reduce the span of the space frame and reduce the amount of steel used per unit area of ​​the space frame; 5. This simplified C-type silo minimizes the overall concrete work and reduces project costs, making it suitable for use in small and medium-sized steel enterprises.

[0040] This utility model proposes a second embodiment of a simplified C-type material storage silo.

[0041] Reference Figure 5 and Figure 6 This embodiment differs from the first embodiment in that, in this embodiment, when the discharge line 5 is located in the middle of the enclosed shed 8, longitudinal partition walls 1 are provided on both sides of the enclosed shed 8, the cross-section of the transverse partition wall 2 is a right trapezoid, and the column 43 is located in the middle of the two discharge lines 5. In this embodiment, the bottoms of the two outer frames 41 of the steel structure grid 4 are respectively inserted into the interior of the two longitudinal partition walls 1, that is, the longitudinal partition walls 1 and the bottom of the steel structure grid 4 are combined, thereby improving the overall structural strength.

[0042] This utility model proposes a third embodiment of a simplified C-type material storage silo.

[0043] Reference Figure 7This embodiment differs from the first embodiment described above in that, in this embodiment, the feeding line 5 includes a long cantilever unloading trolley 9 fixed to a column. The long cantilever unloading trolley 9 includes a horizontally arranged belt conveyor. The belt conveyor rotates forward or reverse to switch between unloading materials into the material storage compartments on both sides. The length of the belt conveyor is L3, and the inner cross-sectional length of the enclosed material shed is L4. The ratio of L3 to L4 is between 1:2 and 1:10. By rotating forward or reverse, the unloading point position is changed, allowing unloading to occur at either the left or right end of the belt conveyor.

[0044] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
