Description

Technical Field

[0001] This invention relates to the field of solid waste storage and treatment technology, and more specifically, to a lifting base for solid waste storage equipment and a matching lifting storage process. Background Technology

[0002] Solid waste stockpiling refers to the process of transferring and stockpiling solid waste that has been dewatered by a filter press to a designated stockpiling area. Currently, there are two main operating models in the industry.

[0003] The first model involves setting up filter press operations at the source of solid waste. This involves constructing a fixed filter press workshop to produce filter-formed solid waste, which is then transported to a storage site via a long-distance, large conveyor belt. This model has significant drawbacks: firstly, it requires the construction of a filter press workshop, a concrete transfer station, and several kilometers of conveyor corridors, resulting in substantial investment in civil engineering and equipment infrastructure; secondly, the belt conveyor headframes, unloaders, and other equipment for storage place stringent requirements on the concrete foundations. When the storage height is increased, new concrete foundations must be built for different levels, leading to a large workload, long construction period, and the inability to disassemble and reuse the foundations, resulting in significant resource waste when the storage site is changed or equipment is relocated.

[0004] The second model places the filter press directly within the storage area, eliminating the need for long-distance material transportation and significantly reducing transportation-related costs. However, it still cannot avoid the technical challenges posed by the elevation increase. As storage operations progress and the storage height increases, the elevation of the filter press's installation foundation needs to be raised accordingly. Traditional methods require disassembling the entire filter press and reassembling it at the new elevation, resulting in complex procedures and low operational efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting base for solid waste storage equipment and a matching lifting and storage process, in order to solve the technical problems mentioned in the background art.

[0006] This invention is implemented as follows: In a first aspect, this application provides a lifting base for a solid waste storage device, comprising: an outer frame; an inner frame that slidably engages with the outer frame; a hydraulic cylinder system disposed between the outer frame and the inner frame for driving the inner frame to slide relative to the outer frame, so that the inner frame is completely retracted into the outer frame or at least partially extended out of the outer frame; and a cement mold detachably disposed on the outer frame and located at the extended end of the inner frame; wherein the cement mold includes a mold body and an anchor plate embedded in the mold body, the anchor plate being used to connect a support body for lifting engagement with the inner frame.

[0007] Furthermore, based on the aforementioned scheme, both the outer frame and the inner frame are rectangular frames.

[0008] Furthermore, based on the aforementioned scheme, a foot mounting plate is provided on the side of the outer frame away from the extended end of the inner frame, and the foot mounting plate is used to connect with the aforementioned solid waste storage equipment.

[0009] Furthermore, based on the aforementioned scheme, the number of the cement molds is two, and the two cement molds are arranged symmetrically about the central axis of the inner frame; a lifting channel is formed between the two cement molds, the lifting channel is used for the inner frame to pass through, and the anchor plates of the two cement molds are connected to the same support body.

[0010] Furthermore, based on the aforementioned scheme, the mold body and the outer frame are detachably connected by a bolt structure.

[0011] Furthermore, based on the aforementioned solution, the outer frame can also be detachably provided with a positioning pin, which is used to limit the inner frame after the inner frame extends out of the outer frame, so as to prevent the inner frame from retracting.

[0012] Furthermore, based on the aforementioned scheme, the hydraulic cylinder system also includes a displacement sensor, which is used to detect the extension length of the hydraulic cylinder.

[0013] Furthermore, based on the aforementioned scheme, the hydraulic cylinder system also includes a pressure sensor, which is used to detect the pressure of the hydraulic cylinder.

[0014] Secondly, this application also provides a lifting and stacking process for a lifting base used in solid waste stacking equipment, comprising the following steps: S1: Installation preparation, fix at least one of the above-mentioned lifting bases to the initial foundation, and fix the stacking equipment to the above-mentioned outer frame; S2: Initial storage: Start the above-mentioned storage equipment to store solid waste until the storage limit at the current elevation is reached; S3: Overall lifting, start the above-mentioned hydraulic cylinder system, drive the above-mentioned outer frame to rise relative to the above-mentioned inner frame, and lift the above-mentioned stacking equipment and the above-mentioned outer frame as a whole to the predetermined height; S4: Increase the height of the foundation, assemble the above-mentioned cement mold under the above-mentioned outer frame, pour concrete into the above-mentioned cement mold, and embed the above-mentioned anchor plate into the inner wall of the above-mentioned mold body before grouting. After the concrete has solidified, remove the above-mentioned cement mold to form a new cement pier. S5: Lowering the load, controlling the hydraulic cylinder system to depressurize and retract, so that the outer frame is lowered and supported on the newly added cement block, completing a single elevation increase; S6: Support conversion, a support body is fixedly connected between the anchor plates of two adjacent newly added cement piers, so that the support body constitutes a bearing platform; S7: Cyclic stacking, repeating S2 to S6 above, to achieve multiple increases in the elevation of the stacking equipment.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: Regarding the first aspect, the lifting base for solid waste storage equipment provided in this application, in actual use, utilizes the relative sliding fit between the inner and outer frames and the driving action of the hydraulic cylinder system. Without disassembling or relocating the storage equipment, the inner frame extends to lift the outer frame and the upper equipment. Subsequently, detachable cement molds with pre-embedded anchor plates are poured layer by layer below the equipment to form new cement piers. The rigid connection between the support body and the anchor plates constitutes a stable bearing platform, thereby achieving a cyclical and progressive increase in equipment elevation. This solution has the following outstanding advantages: First, it fundamentally eliminates the reliance on large concrete foundations for traditional fixed filter press workshops and long-distance conveying corridors, requiring only simple site hardening for rapid production, significantly reducing investment in civil engineering and equipment infrastructure; Second, through a compact process of "simultaneous storage, lifting, and pouring," it can flexibly and quickly respond to elevation increases while the equipment is continuously operating, completely avoiding the cumbersome process of disassembling and reassembling the entire machine as in traditional methods, significantly improving storage efficiency and site depth utilization; Third, the lifting base... Both the base and the cement mold are detachable and transferable. When a stockpile is full, the entire system can be easily moved to a new site and recast, effectively avoiding the resource waste and economic losses caused by fixed foundations that cannot be disassembled. Fourth, the synchronous and stable lifting of the hydraulic cylinder system, combined with the firm connection between the anchor plate and the support body, provides reliable safety for the high-level stockpiling process. Fifth, the entire process is tightly integrated, making full use of the working gaps in solid waste stockpiling to complete the gradual elevation increase, with almost no impact on effective production time, ensuring the continuity and efficiency of production. In summary, this solution is not only widely applicable to the stockpiling and treatment of various solid wastes such as tailings, phosphogypsum, and slag, but also has high reference value and promotional value for other similar working conditions that require multiple elevation increases of equipment.

[0016] Regarding the second aspect, this application also provides a supporting lifting and stacking process for a lifting base for solid waste stacking equipment. Through a cyclical operation mode of "stacking, lifting, and pouring simultaneously", the stacking equipment can be rapidly raised in elevation without disassembly or relocation, which significantly improves the continuity of operations and greatly reduces infrastructure and construction costs.

[0020] Please refer to Figures 1-6 This application provides a lifting base for a solid waste storage device, comprising: an outer frame 2; an inner frame 4, which is slidably engaged with the outer frame 2; a hydraulic cylinder system 3, which is disposed between the outer frame 2 and the inner frame 4, for driving the inner frame 4 to slide relative to the outer frame 2, so that the inner frame 4 is completely retracted into the outer frame 2 or at least partially extended out of the outer frame 2; and a cement mold 1, which is detachably disposed on the outer frame 2 and located at the extended end of the inner frame 4; wherein the cement mold 1 includes a mold body 101 and an anchor plate 102 pre-embedded in the mold body 101, the anchor plate 102 being used to connect a support body 6 for lifting engagement with the inner frame 4.

[0021] The lifting base for solid waste storage equipment provided in this application utilizes the relative sliding fit between the inner and outer frames 2 and the driving action of the hydraulic cylinder system 3 to lift the outer frame 2 and the upper equipment through the extension of the inner frame 4 without disassembling or moving the storage equipment. Then, a new cement block is formed by pouring detachable cement mold 1 with pre-embedded anchor plates 102 layer by layer under the equipment. The rigid connection between the support body and the anchor plates 102 forms a stable bearing platform, thereby realizing the cyclical and progressive lifting of the equipment elevation. This solution has the following key advantages: First, it fundamentally eliminates the reliance on large concrete foundations for traditional fixed filter press workshops and long-distance conveying corridors, requiring only simple site hardening for rapid production, thus significantly reducing investment in civil engineering and equipment infrastructure. Second, through a compact process of "simultaneous storage, lifting, and pouring," it can flexibly and quickly respond to elevation increases while the equipment is operating continuously, completely avoiding the cumbersome process of disassembling and reassembling the entire machine as in traditional methods, significantly improving storage efficiency and site depth utilization. Third, the lifting base and... All cement molds 1 are detachable and transferable. When a stockpile is full, the entire system can be easily moved to a new site and recast, effectively avoiding the resource waste and economic losses caused by fixed foundations that cannot be disassembled. Fourth, the synchronous and stable lifting of the hydraulic cylinder system 3, combined with the firm connection between the anchor plate 102 and the support body, provides reliable safety for the high-level stockpiling process. Fifth, the entire process is tightly integrated, making full use of the working gaps in solid waste stockpiling to complete the gradual elevation increase, with almost no impact on effective production time, ensuring the continuity and efficiency of production. In summary, this solution is not only widely applicable to the stockpiling and treatment of various solid wastes such as tailings, phosphogypsum, and slag, but also has high reference value and promotional value for other similar working conditions that require multiple elevation increases of equipment.

[0022] It is understood that the aforementioned solid waste storage equipment is a filter press. During the lifting operation, the aforementioned lifting bases are respectively arranged at the four corners of the bottom of the filter press, and at least one set of two adjacent lifting bases are connected by a crossbeam between their outer frames 2. The crossbeam is used to provide auxiliary support for the horizontal movement of the conveyor belt of the filter press.

[0023] The mold body 101 is composed of multiple side plates forming a ring structure, and adjacent side plates are detachably connected by bolts.

[0024] In a preferred embodiment, both the outer frame 2 and the inner frame 4 are rectangular frames.

[0025] In the above embodiments, both the outer frame 2 and the inner frame 4 are rectangular frames. This structure has the characteristics of uniform stress and good overall frame rigidity, which is not only conducive to the assembly and alignment with the storage equipment and hydraulic cylinder system 3, but also compatible with the square arrangement of the cement piers cast on site, thereby improving the overall load-bearing stability and construction convenience.

[0026] Optionally, the rectangular frame is welded from steel profiles, and a base plate can be installed at the bottom of the outer frame 2 for contact with the ground or existing cement pier foundation.

[0027] In a preferred embodiment, the outer frame 2 is provided with a foot mounting plate on the side away from the extended end of the inner frame 4, and the foot mounting plate is used to connect with the solid waste storage equipment.

[0028] In the above embodiments, by setting a foot mounting plate on the side of the outer frame 2 away from the extended end of the inner frame 4, it is convenient to make a stable connection and quick disassembly between the storage equipment and the lifting base. This not only ensures the installation reliability of the equipment during the lifting operation, but also improves the convenience and reuse efficiency of the whole set of equipment when it is transferred between different storage yards.

[0029] In a preferred embodiment, there are two cement molds 1, and the two cement molds 1 are arranged symmetrically about the central axis of the inner frame 4; a lifting channel is formed between the two cement molds 1, the lifting channel is used for the inner frame 4 to pass through, and the anchor plates 102 of the two cement molds 1 are connected to the same support body 6.

[0030] In the above embodiment, by symmetrically arranging the two cement molds 1 about the central axis of the inner frame 4 and forming a lifting channel between them for the inner frame 4 to pass through, it is ensured that the inner frame 4 is not interfered with by the mold structure during the lifting and retraction process, the lifting path is unobstructed and the force is symmetrical and balanced, which is conducive to improving the stability and alignment accuracy of the lifting process. On the other hand, the anchor plates 102 of the two cement molds 1 are connected to the same support body 6, so that the newly formed cement pier and support body constitute a whole bearing structure that cooperates in bearing the force, the force transmission path is clear and the load is evenly distributed, thereby significantly improving the structural safety and reliability of the lifting base under high-level stacking conditions.

[0031] Optionally, each of the above-mentioned cement molds 1 is provided with two anchor plates 102, and the anchor plates 102 of the two cement molds 1 are respectively connected to two support bodies 6, and the two support bodies 6 are simultaneously lifted and cooperated with the inner frame 4.

[0032] In a preferred embodiment, the mold body 101 and the outer frame 2 are detachably connected by bolt structure 5.

[0033] In the above embodiments, the mold body 101 and the outer frame 2 are detachably connected by bolt structure 5, so that the cement mold 1 can be easily dismantled and transferred to the next work cycle for reuse after a single pouring is completed. This reduces the mold configuration cost, improves construction efficiency, facilitates transportation and relocation, and further enhances the reusability and economy of the entire lifting device in different stockpiles.

[0034] In a preferred embodiment, the outer frame 2 may also be detachably provided with a positioning pin 8, which is used to limit the inner frame 4 after the inner frame 4 extends out of the outer frame 2, so as to prevent the inner frame 4 from retracting.

[0035] In the above embodiments, the positioning pin 8 can mechanically lock and limit the inner frame 4 after it extends, preventing the inner frame 4 from retracting due to accidental pressure leakage of the hydraulic system during the lifting process, thereby significantly improving the safety and reliability of the lifting operation. At the same time, the positioning pin 8 can be easily removed after a single lifting is completed, without affecting the cyclic operation of subsequent processes, and has good flexibility and reusability.

[0036] Optionally, a check lock block 7 may also be installed on the positioning pin 8, and the check lock block 7 is located at the top of the inner frame 4 after being installed. The positioning pins 8 are provided at all four corners of the outer frame 2 to improve the stability of the positioning after the outer frame 2 slides relative to the inner frame 4.

[0037] The outer frame 2 is provided with a placement tube 9, and the positioning pin 8 can be placed in the placement tube 9 after being removed.

[0038] In a preferred embodiment, the hydraulic cylinder system 3 further includes a displacement sensor for detecting the extension length of the hydraulic cylinder.

[0039] In the above embodiments, the displacement sensor is used to detect the extension length of the hydraulic cylinder in real time, thereby enabling precise control of the lifting height each time, ensuring that multiple sets of hydraulic cylinders lift and lower synchronously, effectively avoiding equipment tilting or uneven loading due to asynchronous lifting, and significantly improving the accuracy, safety and controllability of the lifting process.

[0040] In a preferred embodiment, the hydraulic cylinder system 3 further includes a pressure sensor for detecting the pressure of the hydraulic cylinder.

[0041] In the above embodiments, the pressure sensor is used to monitor the working pressure of the hydraulic cylinder in real time, thereby accurately judging the lifting load status, effectively preventing the risk of equipment overturning or damage caused by overload or uneven load, providing overload warning and safety guarantee for lifting operations, and further improving the safety and reliability of the system.

[0042] Optionally, the hydraulic cylinder system 3 is connected to a synchronous control system. This synchronous control system is used to monitor the extension length and cylinder pressure of each hydraulic cylinder in real time, and to coordinate the adjustment of multiple cylinders through the hydraulic control valve group to achieve synchronous lifting control of each cylinder. After lifting to the position, the cylinder is locked by a positioning pin 8 set on the outer frame 2 to lock the position of the cylinder after lifting is completed, preventing accidental fall, thereby further ensuring the overall safety and reliability of lifting and load-bearing operations.
