Description

Technical Field

[0001] This invention belongs to the field of material stable conveying equipment and cement calcination alternative fuel technology, and particularly relates to a light bulk material transfer and storage system. Background Technology

[0002] Against the backdrop of dual carbon targets, soaring coal prices, and a sluggish market, alternative fuels are gradually becoming an important pathway for carbon emission reduction in cement manufacturing and a crucial means of reducing coal consumption in the cement industry at present. Industrial waste, domestic waste, aged waste, bulky waste, biomass, and waste tires can all be used as alternative fuels. After being processed by comprehensive equipment such as pre-crushing, magnetic separation, and fine crushing, these solid wastes are fed into the kiln tail system of cement plants to replace traditional fossil fuel combustion. To ensure the efficient use of these fuels, a stable feeding system, including silos, breakers, and material placing vehicles, plays a vital role. Otherwise, incomplete combustion of alternative fuels may occur during use, leading to crusting and blockage in the kiln system and disrupting the stable balance of the thermal system.

[0003] Currently, the main material conveying system used in the market is the chain plate feeder. Chain plate feeders can store and convey a certain volume of material and have a certain load-bearing capacity. However, limited by the height, width, and maximum power of the motor, the volume of material that can be stored and the load-bearing capacity are very limited. Continuous manual feeding is required, and chain plate feeders cannot automatically distribute or disperse materials. Furthermore, with the increasing rate of material replacement, using chain plate conveyors cannot meet the demands of high replacement rates. Moreover, due to inherent defects in chain plate conveyors—unstable start-up, circular material conveying, chain plate misalignment, etc.—they suffer from poor reliability and a high failure rate, increasing subsequent maintenance work. Summary of the Invention

[0004] The purpose of this application is to provide a lightweight bulk material transshipment and storage system to solve the technical problems in the prior art.

[0005] The technical solution adopted in this application embodiment to solve the technical problems existing in the prior art is as follows: A lightweight bulk material transshipment and storage system includes an automatic material distribution unit and a walking floor unit. The automatic material distribution unit comprises a fixed belt conveyor and a mobile reversible belt conveyor. During the movement of the mobile reversible belt conveyor, the discharge end of the fixed belt conveyor is always above the mobile reversible belt conveyor. A radar level gauge is located at the discharge end of the mobile reversible belt conveyor and is aligned with the walking floor unit. The radar level gauge transmits the material level information of the walking floor unit directly below the discharge end of the mobile reversible belt conveyor to the control system. The output of the control system is connected to the automatic material distribution unit.

[0006] With the coordinated operation of fixed conveyors, mobile reversible conveyors, and radar level gauges, materials can be continuously and evenly distributed on the walking floor, ensuring continuous supply of alternative fuels at the physical level while effectively maintaining the stability of the thermal regime.

[0007] The embodiments of this application may also employ the following technical solutions: In the aforementioned lightweight bulk material transshipment and storage system, the fixed belt conveyor further includes a fixed belt support, a fixed belt, and a fixed belt motor. The fixed belt is installed on the fixed belt support, receives materials conveyed from the upper-level system, and the fixed belt motor drives the fixed belt to deliver the materials to the movable and reversible belt conveyor.

[0008] In the aforementioned lightweight bulk material transshipment and storage system, the mobile reversible belt conveyor further includes a mobile trolley brake motor and a mobile trolley stepper motor. A mobile reversible belt is installed on the mobile reversible belt conveyor. The mobile trolley brake motor drives the mobile reversible belt conveyor to move, and the mobile trolley stepper motor drives the mobile reversible belt to rotate.

[0009] In the aforementioned lightweight bulk material transshipment and storage system, the stepping floor unit further includes a guide rail assembly and a conveying assembly that moves on the guide rail assembly. The conveying assembly includes several sets of floor profiles, each set of floor profiles being connected as a whole by push plates, and each set of floor profiles being synchronously driven by at least two hydraulic cylinders.

[0010] In the aforementioned lightweight bulk material transshipment and storage system, the floor profiles extend outwards on both sides to form inverted "V" shaped protrusions, and the protrusions of two adjacent floor profiles overlap each other.

[0011] In the aforementioned lightweight bulk material transshipment and storage system, furthermore, limit blocks are installed between the floor profiles.

[0012] In the aforementioned lightweight bulk material transshipment and storage system, the lightweight bulk material transshipment and storage system further includes a material feeding roller unit, which includes at least two material feeding rollers. The roller shaft of the material feeding roller is a hollow shaft, and the two ends of the hollow shaft are respectively connected to a fixed end shaft head and a movable end shaft head. A reducer is installed on the fixed end shaft head, and the two ends of the material feeding roller are sealed by roller seals.

[0013] In the aforementioned lightweight bulk material transshipment and storage system, furthermore, the roller surface of the feeding roller is distributed with feeding plates of different shapes. The feeding plates include feeding plate A, feeding plate B and feeding plate C. Feeding plate A and feeding plate B are staggered on the roller and perpendicular to each other, while feeding plate C is distributed at both ends of the roller and covers the roller for sealing.

[0014] In the aforementioned lightweight bulk material transshipment and storage system, the two ends of the feeding roller are respectively supported on roller support plates.

[0015] A light bulk material transshipment and storage process, wherein the light bulk material transshipment and storage process adopts any one of the light bulk material transshipment and storage systems described above.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following beneficial effects: 1. This invention provides a device that integrates automatic feeding, uniform material dispersion, and high-capacity storage functions for alternative fuels, and can continuously, stably, efficiently, and controllably transport the alternative fuels. Stable transport can effectively control the fluctuation range of the calorific value of the alternative fuels and the concentration of harmful components such as chlorine and sulfur, ensuring the stability of the thermal regime of the cement firing system, and playing a crucial role in the stable use of alternative fuels in the cement firing system.

[0017] At the same time, the present invention has a simple structure, low cost, few precision parts, and the entire system is basically installed externally. Therefore, the entire system has high reliability, low failure rate, and very little maintenance.

[0018] 2. The stepping floor unit of the present invention has the characteristics of heavy load bearing, large capacity, good wear resistance, and leak prevention. The precise cooperation between the conveying component and the guide rail component of the stepping floor unit gives the stepping floor unit good sliding and force-bearing effects, avoiding uneven wear between the contact surfaces over time, which would lead to an imbalance of forces in the entire system and thus affect the stability of the hydraulic system and the supporting structures.

[0019] The guide rail assembly is made of PE board, which will not wear or deform when subjected to large loads, and will not cause the hydraulic system to run sluggishly and become unusable.

[0020] Meanwhile, a redundant safety system controlled by the hydraulic system program was added to each independent hydraulic drive unit. When the hydraulic thrust reaches the limit load, for example, when the pressure reaches 15MPa, the overload self-locking device will be activated and the equipment will trip to prevent it from breaking due to excessive pressure. This solves the problems of limited storage material volume and low load-bearing capacity.

[0021] 3. The concave-convex seal of the sealing component of the present invention has a good anti-leakage effect. Because the sealing component adopts a non-contact labyrinth seal structure, it can effectively solve the leakage problem when there is relative movement between floor profiles, and solve the problem of large amount of maintenance work in the later stage.

[0022] 4. The material-feeding roller of the present invention can effectively solve the problem of equipment jamming during material conveying. The present invention shortens the sealing dimension between the material-feeding roller and the housing, and expands the material-feeding plates C on both sides of the material-feeding roller so that the material-feeding plates C can cover the roller seal that is prone to material accumulation. During the uniform rotation of the material-feeding roller, the material-feeding plates C will disperse the material accumulated at the roller seal, preventing it from accumulating at the roller seal, thereby effectively solving the problem of conveying equipment jamming.

[0023] Meanwhile, since the position of the feeding roller in both the height and material flow directions plays a crucial role in whether the material can be transported smoothly and evenly, the feeding roller of this invention can be adjusted in both the height and material flow directions. That is, the position of the feeding roller can be changed according to the physical characteristics of different materials. Specifically, for biomass alternative fuels, the distance from the top of the roller teeth to the material bed is 0-400mm, and in the material flow direction, the center line of the roller is flush with the end of the material bed; while for municipal solid waste alternative fuels, the distance from the top of the roller teeth to the material bed is 50-300mm, and in the material flow direction, the center line of the roller is 0-500mm from the end of the material bed.

[0024] In summary, this invention solves the problem of roller jamming in silos on the market by designing different roller teeth according to different materials, adjusting the arrangement of rollers in the material flow direction and vertical direction, and adjusting the stroke of the floor to be less than the height of the roller teeth, thus ensuring the continuous and stable operation of the entire system.

Reducer. Detailed Implementation

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] Example 1: This embodiment includes an automatic material feeding unit, a material feeding roller unit, a stepping floor unit, a hydraulic drive unit, a housing assembly 1, and a support structure 2. The housing assembly 1 includes a steel plate, and the support structure 2 is a box-type structure with strong bending and shear resistance to ensure stable operation of the hydraulic system. It includes a hydraulic crossbeam and a guide rail crossbeam for supporting the hopper.

[0038] Stepping floor unit: includes multiple guide rail assemblies, sealing assemblies, and conveying assemblies.

[0039] In this embodiment, the guide rail assembly consists of multiple rectangular PE plates. The guide rail assembly features self-lubrication, low coefficient of friction, and wear and pressure resistance.

[0040] The conveying assembly includes several sets of floor profiles 31; in this embodiment, three sets of floor profiles may be used. Each set of floor profiles 31 in the conveying assembly is connected as a whole by different push plates 32, and each set of floor profiles 31 is relatively independent. Each set of floor profiles 31 is driven synchronously by two hydraulic cylinders 34. Each set of floor profiles 31 is supported on the guide rail assembly and can slide back and forth. Limiting blocks 33 are installed between the floor profiles 31 and are used to limit their movement.

[0041] The sealing components are installed on the floor profile 31 and are the protruding parts on both sides of the floor profile 31. The sealing components of adjacent rows of floor profiles 31 overlap each other but maintain a certain gap. (See attached instruction manual) Figure 3 As shown, the sealing assembly includes a V-shaped sealing plate 35 and a wear-resistant plate 36, with the V-shaped sealing plate 35 covering the wear-resistant plate 36.

[0042] The sealing assembly adopts a non-contact labyrinth structure, with two inverted "V" shaped V-shaped sealing plates 35 interlocked, and a wear-resistant plate 36 sandwiched between the two V-shaped sealing plates 35 and fixed on one of the V-shaped sealing plates 35, achieving a better sealing effect.

[0043] The hydraulic drive unit includes a hydraulic cylinder 34, a push plate 32, a fixed support 37, and a movable support 38. The number of hydraulic drive units is the same as the number of sets of floor profiles 31.

[0044] In this embodiment, since three sets of floor profiles 31 are used, the hydraulic drive unit includes three sets of hydraulic cylinders 34, a fixed support 37, and a movable support 38. Each set of hydraulic cylinders 34 contains two hydraulic cylinders 34, and each set of floor profiles 31 is driven by the two hydraulic cylinders 34. The two hydraulic cylinders of each set of floor profiles 31 are on the same cross section. The movable support 38 of each hydraulic cylinder 34 is installed on the corresponding floor profile 31, and the fixed support 37 is installed on the hydraulic crossbeam of the support frame 2.

[0045] As per the instruction manual Figure 6 As shown, each push plate 32 has several connecting plates 39, which are connected to the floor profiles 31 in the same group. The three push plates 32 connect all the floor profiles 31 to form a fully controllable step floor unit.

[0046] Displacement sensors for monitoring the travel of floor profiles are installed on the support frame 2. The displacement sensors feed back the displacement value of the floor profiles 31 to the central control screen, and then the speed and travel are manually adjusted.

[0047] Material feeding roller unit: includes feeding plate for dispersing materials, roller shaft and bearing housing 708.

[0048] This embodiment includes at least two feeding roller assemblies 4. The roller shaft is a hollow shaft 701, with both ends bolted to a fixed end shaft head 702 and a movable end shaft head 703, respectively. A reducer 710 is mounted on the fixed end shaft head 702 to drive the roller 704 to rotate at different speeds. Both ends of the feeding roller 4 are sealed by roller seals 705.

[0049] The surface of the feeding roller 4 (704) is covered with feeding plates of different shapes to disperse accumulated materials. The feeding plates have a trapezoidal profile and are arranged in a crisscross pattern on the feeding roller 4 (704) for effective and even distribution of various materials. The feeding plates include feeding plate A706, feeding plate B707, and feeding plate C709. (See attached instruction manual.) Figure 8 As shown, the feeding plates A706 and B707 are staggered on the roller 704 and perpendicular to each other. The feeding plate C709 is distributed at both ends of the roller 704 and covers the roller seal 705.

[0050] The two ends of the feeding roller 4 are respectively supported on the roller support plate 11, which can be adjusted up and down and back and forth. The roller support plate 11 and the housing assembly 1 are connected by bolts. The housing assembly 1 has several bolt holes evenly arranged in the vertical and horizontal directions. When the feeding roller 4 is adjusted up and down and back and forth to the required position, the corresponding bolts are fixed. Thus, the height of the feeding roller 4 can be adjusted according to the height of the material layer. When the required unloading amount is large, the height is increased, and when the amount is small, the height is decreased.

[0051] Automatic material feeding unit: includes a moving trolley, radar level gauge 7, and automatic control system.

[0052] The stationary belt conveyor 5 includes a stationary belt support 51, a stationary belt 52, and a stationary belt motor 53. The mobile reversible belt conveyor 6 includes a mobile trolley brake motor 61 and a mobile trolley stepper motor 62.

[0053] The fixed belt 51 is installed on the fixed belt support 51. The fixed belt 51 receives materials conveyed from the upper system. The fixed belt motor 53 drives the fixed belt 51 to convey the materials to the mobile reversible belt conveyor 6 at a certain speed.

[0054] A mobile reversible belt is installed on the mobile reversible belt conveyor 6. The mobile trolley brake motor 61 drives the mobile reversible belt conveyor 6 to move, and the mobile trolley stepper motor 62 drives the mobile reversible belt to rotate. The automatic control system controls the moving distance of the mobile trolley brake motor 61 and the material distribution speed of the mobile trolley stepper motor 62 based on the material level information in the hopper (i.e., the material on the floor profile 31) fed back by the radar level gauge 7, thereby achieving uniform material distribution.

[0055] Work process: Material is conveyed from the upper system to the fixed belt conveyor 5, and then transferred to the mobile reversible belt conveyor 6. From the mobile reversible belt conveyor 6, the material is evenly distributed onto the floor profile 31. To prevent material from flowing in clumps from the floor profile 31 into the lower system, a feeding roller 4 is arranged at the discharge end to avoid scattering the material as it falls in clumps, thus ensuring more even material distribution on the floor profile 31.

[0056] This embodiment can be applied to a cement firing alternative fuel system, and has the advantages of large material storage capacity, strong load-bearing capacity, automatic material distribution, uniform material dispersion, and stable and uniform feeding and unloading. It is based on the principle of step conveying and integrates storage, conveying, and dispersion functions.

[0057] This embodiment achieves stable material transportation, ensuring continuous supply of alternative fuels at the physical level while effectively maintaining the stability of the thermal regime. Generally, the calorific value of alternative fuels (RDF, biomass, etc.) can fluctuate by approximately ±40% (compared to ±5% for traditional pulverized coal), and the concentration of harmful elements such as chlorine and sulfur can fluctuate by approximately 70%. Stable transportation of alternative fuels can effectively reduce the fluctuation range of calorific value and harmful elements. A smaller fluctuation range is more conducive to improving the temperature control accuracy of the decomposition furnace, the stability of raw material decomposition kinetics, and controlling the f-CaO range to improve clinker quality. This breaks the vicious cycle of "calorific value fluctuation - decomposition rate - kiln operating conditions," further increasing the thermal substitution rate of alternative fuels and promoting the cement industry to achieve "three lows and one high" (low heat consumption, low emissions, low cost, and high efficiency).

[0058] Example 2: The material conveying method in this embodiment is mainly divided into five stages: initial state, all floor profile components moving forward, floor profile component A retracting, floor profile component B retracting, and floor profile component C retracting. The moving floor profile unit repeats this process, carrying the material along a specific direction to finally complete unloading.

[0059] In the initial state, all floor profiles 31 are one step away from the end of the track (i.e., the other end of the feed roller).

[0060] The entire floor profile assembly is in the following stages: under the action of the hydraulic control system, all hydraulic cylinders 34 simultaneously push all floor profiles 31 forward by one step length. At this time, the material in the hopper is equivalent to being conveyed forward by one step length as a whole.

[0061] Driven by hydraulic cylinder group A, floor profile assembly A retracts to the initial position. At this time, the material on floor profile assembly A is evenly discharged during the uniform retraction of floor profile 31. When floor profile assembly A retracts to the initial state.

[0062] Then, under the action of the hydraulic control system, the floor profile component B begins to retreat at a constant speed back to its initial state.

[0063] Finally, when the floor profile component C retracts to its initial state.

[0064] Example 3: Traditional concrete placing vehicles require manual intervention, which is not only inefficient but also makes it impossible to precisely control the shape of the material pile, thus failing to achieve material homogenization and stable transportation of alternative fuels.

[0065] In this embodiment, the mobile reversible belt conveyor 6 receives materials from the fixed belt conveyor 5. As needed, the mobile reversible belt conveyor 6 reciprocates on the hopper track to unload materials. The automatic control system collects data based on the material level information fed back by the radar level gauge 7, and the calculated data is transmitted to the mobile reversible belt conveyor 6 through the control system to complete the precise positioning of the mobile reversible belt conveyor 6 and replenish materials when needed.

[0066] Work process: Initially, the trolley brake motor 61 drives the movable reversible belt conveyor 6 a certain distance each time, then pauses for a period of time. During this time, the trolley stepper motor 62 drives the movable reversible belt to rotate and unload material; the rotation speed is adjustable. When the radar level gauge 7 detects the material level, the trolley moves another set distance, pauses for a period of time to distribute material, until it has traveled the entire hopper.

[0067] Then, the mobile reversible belt conveyor 6 reciprocates at a certain speed. When the radar level gauge 7 detects that the material level at a certain position has not reached the set value, unloading begins until the material level reaches the set value, thus ensuring that the material level in the entire silo reaches the set value. During the reciprocating motion, the mobile trolley brake motor 61 moves simultaneously, while the mobile trolley stepper motor 62 drives the mobile reversible belt to rotate at a certain speed. The two motors work together to achieve the purpose of material distribution. The speed of both motors can be adjusted according to the required amount of material.

[0068] This embodiment uses the coordinated control of the mobile reversible belt conveyor 6 and the radar level gauge 7 to dynamically adjust the operating parameters of the mobile reversible belt conveyor 6, thereby solving the problems of uneven stacking and segregation caused by the reliance on manual intervention in traditional material placing vehicles.

[0069] The automatic control system in this embodiment has two modes: remote control and on-site control. The unloading process of lightweight bulk materials will generate a lot of dust. Long-term exposure to dusty environments is extremely detrimental to the health of workers. The remote control mode of the automatic control system greatly reduces the harm to personnel. Only in a few cases is on-site operation required.

[0070] In summary, the present invention provides a lightweight bulk material transshipment and storage system.

[0071] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
