Description

Technical Field

[0001] The invention relates to the technical field of waste slag fields, and in particular to a chute structure for waste slag. Background Art

[0002] When constructing roads and railways in mountainous areas, due to the limitations of terrain conditions, excavation of tunnels and roadbeds is essential. Engineering excavation will inevitably produce waste rock and soil debris. Due to the imperfect construction technology and construction management, as well as the limitations of transportation, terrain conditions and engineering investment, the waste slag is often dumped and piled in the valley terrain around the construction site, thus forming waste slag sites of varying sizes. When dumping rock and soil debris, it is necessary to divert the waste slag through a waste slag chute set along the waste slag slope.

[0003] Although there are many different types of slag chute structures used in waste dumps to meet different diversion needs, most of them are cast on-site with cement and concrete, and their positions are fixed and cannot be transferred or reused. A single waste dump often requires multiple slag chutes, and the length of the slag chute is huge. Therefore, this method requires a large amount of materials and resources to repeatedly build the chute structure, and the construction cost is high. Summary of the invention

[0004] The purpose of the present invention is to overcome the technical problem that in the prior art, the waste slag chute is cast on site with cement and concrete, cannot be reused, requires a large amount of materials and resources to repeatedly build the waste slag chute, resulting in high construction costs, and provide a waste slag chute structure.

[0005] In a first aspect, the present invention provides a chute structure for waste slag, comprising a waste slag chute, the waste slag chute comprising at least two chute segments, the chute segments being distributed along the length direction of the waste slag chute, and two adjacent chute segments being detachably connected to each other; the inner wall of the waste slag chute is connected with at least two energy dissipation barriers, which are spaced apart along the length direction of the waste slag chute; the outer wall of the waste slag chute is detachably connected with at least two mounting seats, which are spaced apart along the length direction of the waste slag chute, and the end of the mounting seat away from the waste chute is used for connection with a waste slag slope.

[0006] The slag chute structure of the present scheme includes multiple slide sections, which are connected to the slag slope through a mounting seat, and the connection between two adjacent slide sections and between the slag chute and the mounting seat are detachable; when two adjacent slide sections are connected to each other, the slag chute is connected to the mounting seat, and the mounting seat is connected to the slag slope, the present scheme can be used to transport the slag from top to bottom along the slag slope; and the energy dissipation barrier can reduce the speed of the slag in the slag chute, avoiding the situation where the slag has excessive impact on the slag chute, causing damage or disintegration of the slag chute.

[0007] After the waste slag conveying operation is completed, the connection between two adjacent chute sections and between the waste slag chute and the mounting seat is released, and the chute section can be removed from the waste slag slope; when other waste slag sites need to use the waste slag chute, the above chute sections can be transported to the designated location and reassembled.

[0008] As can be seen from the above, this scheme changes the waste chute into a segmented structure. After completing the waste conveying operation at the corresponding position, each chute segment can be disassembled from the waste slope, transported and reinstalled at other locations, and used for the waste conveying operation at the corresponding position, thereby realizing the recycling and reuse of the waste chute, and there is no need to repeatedly build a huge waste chute, thus greatly reducing the material consumption, construction period and construction cost of the waste chute structure.

[0009] Preferably, the slideway segments are cylindrical members.

[0010] This scheme recommends the use of cylindrical slide segments, that is, the cross-section of the slide segment is a closed figure, which can prevent the waste slag from leaking from the slide segment and prevent external foreign matter from entering the slide segment, thereby ensuring the stable operation of the waste slag chute.

[0011] Preferably, one end of the slide segment is a large end, and the other end of the slide segment is a small end, and the inner dimension of the large end matches the outer dimension of the small end; in two adjacent slide segments, the small segment of one slide segment is inserted into the large end of the other slide segment.

[0012] This solution enables two adjacent slide sections to be spliced ​​end to end, which can facilitate rapid positioning when assembling the slag slide, thereby speeding up the construction progress; on the other hand, it can also reduce the possibility of slag leakage from between two adjacent slides.

[0013] Preferably, the end of the chute segment close to the inlet of the waste chute is the large end.

[0014] In this solution, the end of the chute segment close to the entrance of the waste chute is the large end. When the waste is transferred between two adjacent chute segments, the waste will enter the large end of another chute segment from the small end of one chute segment. In this way, without setting a sealing structure between the two adjacent waste segments, it is ensured that all the waste can be transferred from one chute segment to another chute segment without leakage.

[0015] Preferably, an inspection port is provided on the waste chute, the position of which matches the position of the energy dissipation barrier, and a cover plate is provided on the inspection port, which is detachably connected to the waste chute, or the cover plate can be opened or closed.

[0016] Since the flow area of ​​the slag chute will decrease to a certain extent at the energy dissipation baffle, there is a possibility that the slag will be stuck between the energy dissipation baffle and the inner wall of the slag chute; this scheme provides an inspection port and a corresponding cover at the position of the energy dissipation baffle, and the slag chute is closed or installed with the cover when the slag chute is working normally, which can prevent external foreign matter from entering the slag chute or the slag from leaking from the inspection port; and if the energy dissipation baffle is blocked, opening or removing the cover will facilitate the staff to clean the blockage.

[0017] Preferably, a clamp is provided on the mounting seat, the shape of the clamp matches the cross-sectional shape of the waste chute, and the waste chute passes through the clamp.

[0018] This proposal recommends one specific connection form between the waste chute and the mounting base.

[0019] Preferably, the height of the energy dissipation barrier relative to the inner wall of the waste chute is smaller along the length direction of the waste chute as it approaches the entrance of the waste chute.

[0020] This solution gradually increases the height of the energy dissipation baffle relative to the inner wall of the slag chute along the sliding direction of the slag, which can guide the slag more gently, thereby avoiding rigid impact between the slag and the energy dissipation baffle, and further avoiding damage to the energy dissipation baffle and even the slag chute under impact.

[0021] Preferably, the outer wall of the waste chute is connected with at least one thrust structure, and the thrust structure is located on a side of the mounting seat close to the entrance of the waste chute, and the thrust structure can abut against the mounting seat.

[0022] When the slag slides in the slag chute, it will exert a downward thrust on the slag chute along the length direction of the slag chute. Therefore, this solution provides a thrust stop structure between the slag chute and the mounting seat to prevent the slag chute from moving under the action of the thrust.

[0023] Preferably, a side of the mounting seat away from the waste chute is connected to a concrete base.

[0024] In this solution, a concrete base is arranged on the bottom surface of the mounting seat, which can better transfer the load generated by the slag chute and the slag inside it to the slag slope, thereby ensuring the stability of the slag chute.

[0025] Preferably, the waste chute is a metal component.

[0026] Compared with concrete, metal has a higher strength-to-weight ratio, ductility and plasticity. Therefore, this plan recommends a material for the slag chute that can reduce the weight of the slag chute, thereby facilitating the transportation of the slag chute for reuse and obtaining better processing quality; and if the slag chute is deformed under the impact of the slag, the metal slag chute also has better maintainability.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention provides a chute structure for waste slag, which divides a waste slag chute into a plurality of chute sections, and connects the chute sections to a waste slag slope through a mounting seat, and the connection between two adjacent chute sections and between the waste slag chute and the mounting seat is detachable; after completing the waste slag conveying operation at a corresponding position, each chute section can be disassembled from the waste slag slope, transported and reinstalled at other positions, and used for the waste slag conveying operation at the corresponding position, thereby realizing the recovery and reuse of the waste slag chute, and there is no need to repeatedly build a huge waste slag chute, so that the material consumption, construction period and construction cost of the waste slag chute structure can be greatly reduced; and the energy dissipation barrier can reduce the speed of the waste slag in the waste slag chute, and avoid the waste slag from having an excessive impact on the waste slag chute, which may cause damage or disintegration of the waste slag chute.

[0042] Example 1

[0043] like Figures 1 to 6 As shown, a chute structure for waste slag comprises a waste slag chute 1, wherein the waste slag chute 1 comprises at least two chute sections 11, wherein the chute sections 11 are distributed along the length direction of the waste slag chute 1, and two adjacent chute sections 11 are detachably connected to each other; the inner wall of the waste slag chute 1 is connected with at least two energy dissipation barriers 12, wherein the energy dissipation barriers 12 are distributed at intervals along the length direction of the waste slag chute 1, and the projected area of ​​the energy dissipation barriers 12 on a plane perpendicular to the length direction of the waste slag chute 1 is smaller than the flow area of ​​the waste slag chute 1; the outer wall of the waste slag chute 1 is detachably connected with at least two mounting seats 2, wherein the mounting seats 2 are distributed at intervals along the length direction of the waste slag chute 1, and the end of the mounting seat 2 away from the waste slag chute 1 is used for connecting with a waste slag slope 7.

[0044] In the above-mentioned embodiment, the waste chute 1 is used to transport waste slag from top to bottom along the waste slag slope 7, and its specific shapes include but are not limited to trough-shaped components and cylindrical components, such as trough-shaped components with a roughly "U"-shaped or semicircular cross-section, or cylindrical components with a roughly rectangular, circular, square-round, or elliptical cross-section; in order to stabilize the waste slag operating environment, the waste chute 1 in this embodiment is preferably a cylindrical component with a circular cross-section, that is, each chute segment 11 is a cylindrical component with a circular cross-section.

[0045] In the above-mentioned embodiment, the specific structural form of the energy dissipation barrier 12 includes but is not limited to a block or a baffle, as long as it is protruding relative to the inner wall of the slag chute 1 and can be used to slow down the speed of the slag; the projected area of ​​the energy dissipation barrier 12 on the plane perpendicular to the length direction of the slag chute 1 is smaller than the flow area of ​​the slag chute 1. For example, for the trough-shaped slag chute 1, the height of the energy dissipation barrier 12 protruding relative to the inner wall of the slag chute 1 is smaller than the depth of the slag chute 1; for the cylindrical slag chute 1, the height of the energy dissipation barrier 12 protruding relative to the inner wall of the slag chute 1 is smaller than the diameter of the slag chute 1.

[0046] In the above-mentioned embodiment, the detachable connection method between two adjacent slide segments 11 includes but is not limited to threaded connection, mortise and tenon connection, and plug-in connection; for example, a flange or a lap plate is set at the end of the slide segment 11, and the flanges or lap plates of the two adjacent slide segments 11 are connected together by a threaded connection, or the two opposite ends of the two adjacent slide segments 11 are made to fit together in a concave and convex manner; correspondingly, the detachable connection method between the waste chute 1 and the mounting seat 2 also includes but is not limited to threaded connection, mortise and tenon connection, and plug-in connection. The number of mounting seats 2 is determined according to the fixing requirements, and can be equal to the number of slide segments 11, or can be greater than or less than the number of slide segments 11.

[0047] In an optional embodiment, one end of the slideway segment 11 is a large end 111, and the other end of the slideway segment 11 is a small end 112, and the inner dimension of the large end 111 matches the outer dimension of the small end 112; in two adjacent slideway segments 11, the small segment of one slideway segment 11 is inserted into the large end 111 of the other slideway segment 11. The inner dimension refers to the dimension of the inner wall of the slideway segment 11, and the outer dimension refers to the dimension of the outer wall of the slideway segment 11. For example, for a slideway segment 11 with a circular cross section, such as Figure 2 As shown, the inner diameter D1 of the large end 111 is greater than or equal to the outer diameter D2 of the small end 112 . For the slideway segment 11 with a square cross-section, the side length of the inner wall of the large end 111 is greater than or equal to the side length of the outer wall of the small end 112 .

[0048] In the above embodiment, the end of the chute segment 11 close to the entrance of the waste chute 1 is the large end 111. Figure 1 The slideway segment 11 shown has a large end 111 at its upper end and a small end 112 at its lower end.

[0049] In the above embodiment, the inner diameter of the large end 111 of the chute segment 11 is larger as it is closer to the entrance of the waste chute 1, for example Figure 2 As shown, the large end 111 of the slide segment 11 is in a trumpet shape, which can guide the small end 112 of another slide segment 11 when assembling the waste chute 1, thereby improving the assembly efficiency.

[0050] In an optional embodiment, the waste chute 1 includes an inclined section and a horizontal section, for example Figure 1 As shown, the horizontal section can prevent the waste slag from accelerating in the waste slag chute 1 through the slope section, thereby obtaining excessive kinetic energy and violently colliding with the inner wall of the waste chute 1; optionally, an energy dissipation barrier 12 can be further provided at the connection between the slope section and the horizontal section, thereby reducing the impact of the waste slag on the horizontal section.

[0051] In an optional embodiment, an inspection port 14 is provided on the waste chute 1, and the position of the inspection port 14 matches the position of the energy dissipation barrier 12. A cover plate 5 is provided on the inspection port 14, and the cover plate 5 is detachably connected to the waste chute 1, or the cover plate 5 can be opened or closed.

[0052] In the above embodiment, if Figure 5 As shown, one side of the cover plate 5 is rotatably connected to one side of the slide segment 11 via a rotating shaft 51, and the other side of the cover plate 5 is detachably connected to the other side of the slide segment 11 via a threaded connector. By removing the threaded connector, the cover plate 5 can be opened or closed by rotation, and by installing the threaded connector, the cover plate 5 can be locked in the closed position.

[0053] In an optional embodiment, the height of the energy dissipation barrier 12 relative to the inner wall of the waste chute 1 is, for example Figure 6The D1 shown is smaller along the length direction of the waste chute 1 as it approaches the entrance of the waste chute 1. The height of the protrusion of the energy dissipation barrier 12 near the entrance of the waste chute 1 can be made zero, thereby avoiding the rigid collision between the waste and the energy dissipation barrier 12 to the greatest extent.

[0054] In an optional implementation manner, the distance between two adjacent energy dissipation barriers 12 is greater than or equal to 2 m and less than or equal to 3 m.

[0055] In an optional implementation manner, the energy dissipation barrier 12 is welded to the inner wall of the waste chute 1 .

[0056] In an optional embodiment, a clamp 4 is provided on the mounting seat 2, and the clamp 4 includes at least two clamp segments 41, and two adjacent clamp segments 41 are detachably connected, and at least one clamp segment 41 is connected to the mounting seat 2; the clamp segments 41 are connected to each other to form a shape that matches the cross-section of the waste chute 1, and the waste chute 1 can be fixed relative to the mounting seat 2 by passing the clamp 4. For example Figure 3 As shown, for the circular cross-section slideway segment 11, the clamp 4 includes two semicircular clamp segments 41, wherein the lower clamp segment 41 is fixed to the mounting seat 2, and the upper clamp segment 41 can be detachably connected to the upper part of the lower clamp segment 41 through a threaded connector.

[0057] In an optional embodiment, at least one thrust structure 13 is connected to the outer wall of the waste chute 1, and the thrust structure 13 is located on the side of the mounting seat 2 close to the entrance of the waste chute 1, and the thrust structure 13 can abut against the mounting seat 2. Figure 4 As shown, block-shaped thrust structures 13 are provided on both sides of the outer wall of the slide segment 11, and the thrust structure 13 is located on the side of the clamp 4 close to the entrance of the waste chute 1, and the maximum distance between the thrust structures 13 on both sides is greater than the inner diameter of the clamp 4, so that it can abut against one side of the clamp 4, thereby preventing the slide segment 11 from moving downward under the impact of the waste.

[0058] In an optional embodiment, a side of the mounting seat 2 away from the waste chute 1 is connected to a concrete base 3, the projection area of ​​the concrete base 3 on the waste slope 7 is larger than the projection area of ​​the mounting seat 2, and the concrete base 3 is buried underground in the waste slope 7, which can ensure that the mounting seat 2 is reliably connected to the waste slope 7.

[0059] In an optional embodiment, the mounting base 2 is detachably connected to the concrete base 3 via an anchor rod 6, for example Figure 3 shown.

[0060] In an optional embodiment, the waste chute 1 is a metal component, such as 45 steel, stainless steel, or Q235 steel.
