Description

Technical Field

[0001] This application belongs to the field of material conveying technology, specifically relating to a feeding car and a lime kiln feeding system. Background Technology

[0002] Currently, the top opening of the hopper of the loading vehicle is usually open. When materials are transferred, they are easy to drift from the top opening of the hopper, which not only wastes materials but also pollutes the surrounding air environment and affects the health of operators and people around them. Utility Model Content

[0003] In view of this, this application provides a feeding car and a lime kiln feeding system. By setting a switchable sealing cover at the top opening of the hopper, when the sealing cover is in the closed state, it can seal and cooperate with the top opening of the hopper to prevent the lime raw materials being transported during the lime kiln feeding process from leaking from the opening due to transportation bumps and airflow.

[0004] To achieve the above objectives, this application mainly provides the following technical solutions: In one aspect, this application provides a feeding cart, including a hopper and a sealing cover; the sealing cover is disposed at the top opening of the hopper and is switchable between an open state and a closed state relative to the hopper; when the sealing cover is in the open state, the top opening of the hopper is open to allow material to enter; when the sealing cover is in the closed state, the sealing cover is sealed to the top opening of the hopper to close the top opening.

[0005] Optionally, the sealing cover includes a loading cover and a unloading cover; the loading cover and the unloading cover are rotatably disposed at the top opening of the hopper; the loading cover is configured to be opened by manual operation or an external drive to open the top opening of the hopper for material entry during the loading stage; the unloading cover is configured to open automatically with the tilting action of the hopper to open for material discharge during the unloading stage.

[0007] Optionally, both the loading cover and the unloading cover are provided with a fastening part at their free ends, and the fastening part is fastened to the outer edge of the top opening of the hopper.

[0008] Another aspect of this application provides a lime kiln feeding system, including a feeding car and an elevator as described in any of the above claims; the feeding car is detachably or fixedly mounted on the elevator; the elevator is used to drive the feeding car to move up and down in a vertical direction to realize the transfer of materials from the low loading area to the top unloading area of ​​the lime kiln.

[0009] Optionally, when the sealing cover includes a loading cover and a unloading cover, the lime kiln feeding system further includes a closing rope; one end of the closing rope is connected to the loading cover, and the other end is fixed relative to the support frame of the elevator; the closing rope is configured such that: when the elevator drives the loading car down to the low loading area, the closing rope is pulled by the relative displacement between the loading car and the support frame, thereby driving the loading cover to rotate around the first rotating shaft to open; when the elevator drives the loading car up, the pulling force of the closing rope weakens or disappears, and the loading cover rotates in the opposite direction around the first rotating shaft to close under its own gravity.

[0010] Optionally, the upper surface of the loading cover plate away from the first rotating shaft is provided with a hanging ear, which is used to thread and fix the end of the opening and closing rope.

[0012] Optionally, when the hopper tilts with the feeding car, the discharge cover plate rotates and opens around the second axis under the pressure of the material's gravity or the inertia of the hopper tilting, so that the material in the hopper can be discharged into the lime kiln.

[0013] Optionally, when the hopper tilts with the loading trolley, the loading cover is kept closed by the continuous pulling of the opening and closing rope.

This effectively prevents the material from scattering from the opening due to bumps, airflow and other factors during transportation, thereby reducing material waste, lowering production costs, preventing dust pollution of the surrounding air, protecting the health of operators and surrounding personnel, and improving the stability and environmental friendliness of material transfer, thus meeting the needs of efficient and clean production.

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] See Figure 1 As shown, according to an embodiment of this application, a feeding cart 100 is provided, including a hopper 101 and a sealing cover 102; the sealing cover 102 is disposed at the top opening of the hopper 101 and can switch between an open state and a closed state relative to the hopper 101; when the sealing cover 102 is in the open state, the top opening of the hopper 101 is open to allow material to enter; when the sealing cover 102 is in the closed state, the sealing cover 102 and the top opening of the hopper 101 are sealed together to close the top opening.

[0022] The loading cart 100 provided in the embodiments of this application has a switchable sealing cover 102 at the top opening of the hopper 101. The cover can remain open when materials are loaded to ensure smooth loading, and switch to closed during the transfer process to form a sealed fit with the top opening of the hopper 101. This effectively prevents materials from scattering from the opening due to bumps, airflow and other factors during transportation. This reduces material waste, lowers production costs, and prevents dust pollution of the surrounding air, protecting the health of operators and surrounding personnel. In turn, it improves the stability and environmental friendliness of material transfer and meets the needs of efficient and clean production.

[0023] The hopper 101 serves as the main body for carrying materials, and its top is provided with an opening for materials to enter. It can be understood that when the feeding car 100 is used in the lime kiln feeding system, the material carried in the hopper 101 is lime raw material.

[0024] The sealing cover 102 is installed at the top opening of the hopper 101, and the sealing cover 102 is movable relative to the hopper 101.

[0025] Specifically, in practical applications, the sealing cover 102 has two switchable states: when it is in the open state, the sealing cover 102 does not block the top opening of the hopper 101, and the opening is completely open. At this time, the material can be smoothly loaded into the hopper 101 through the opening to meet the feeding requirements; when switched to the closed state, the sealing cover 102 is fastened to the top opening of the hopper 101 to form a sealing effect and close the opening. At this time, the inside of the hopper 101 is isolated from the outside.

[0026] In the above embodiments, see Figure 1 As shown, the sealing cover 102 includes a loading cover 1021 and a unloading cover 1022; the loading cover 1021 and the unloading cover 1022 are rotatably disposed at the top opening of the hopper 101; the loading cover 1021 is configured to be opened by manual operation or an external drive to open the top opening of the hopper 101 for material to enter during the loading stage; the unloading cover 1022 is configured to be automatically opened with the tilting action of the hopper 101 to open for material to be discharged during the unloading stage.

[0027] Here, by splitting the sealing cover 102 into a loading cover 1021 and a unloading cover 1022, the practicality and sealing performance of the loading vehicle 100 in different operating stages can be balanced. Specifically, the loading cover 1021 can be opened manually or by an external drive, flexibly opening the top opening of the hopper 101 during the loading stage, facilitating rapid material loading without affecting loading efficiency; the unloading cover 1022 opens automatically with the tilting action of the hopper 101, opening the opening for material unloading during the unloading stage without additional operation, simplifying the unloading process and reducing manual intervention costs; at the same time, the loading cover 1021 and the unloading cover 1022 correspond to different operating stages, and when not in operation, they can cooperate with the top opening of the hopper 101 to effectively prevent material leakage or scattering during the transfer process, reducing material waste, protecting the surrounding environment, and improving the overall automation and convenience of the loading vehicle 100, adapting to the high-efficiency operating needs of various material transfer scenarios.

[0028] The loading cover plate 1021 and the unloading cover plate 1022 are both installed at the top opening of the hopper 101 by means of rotation, such as hinge connection, and can rotate relative to the hopper 101 around the rotation axis, thereby realizing the opening or closing of the opening.

[0029] Specifically, during the loading stage, the loading cover 1021 can be opened by the operator directly moving it or by a power device such as a cylinder or motor. At this time, the top opening of the hopper 101 is opened, allowing the material to smoothly enter the hopper 101. During the unloading stage, when the hopper 101 tilts and pours material, the unloading cover 1022 will automatically flip open using the gravity generated by the tilting of the hopper 101, without the need for additional manual or power operation, allowing the material to be discharged from the opening. After the loading and unloading operations are completed, the loading cover 1021 and the unloading cover 1022 can return to the closed state under their own weight, working together with the top opening of the hopper 101 to seal the hopper 101 and ensure that the material inside the hopper 101 does not leak during the transfer process.

[0030] In the above embodiments, see Figure 1 As shown, a support base 103 is provided at the top opening of the hopper 101; the loading cover plate 1021 is rotatably connected to one side of the support base 103 via a first rotating shaft 104, and the unloading cover plate 1022 is rotatably connected to the other side of the support base 103 via a second rotating shaft 105; the first rotating shaft 104 and the second rotating shaft 105 are parallel in axial direction and both extend along the width direction of the top opening of the hopper 101.

[0031] Here, by setting a support base 103 at the top opening of the hopper 101, and rotatably connecting the loading cover plate 1021 and the unloading cover plate 1022 to both sides of the support base 103 via a first rotating shaft 104 and a second rotating shaft 105 extending parallel to and along the width of the opening, a stable mounting base is provided for the loading cover plate 1021 and the unloading cover plate 1022, ensuring the structural reliability of their rotation process. Furthermore, the first rotating shaft 104 and the second rotating shaft 105 extending parallel to and in the same direction ensure that the loading cover plate 1021 and the unloading cover plate 1022 are connected... The opening direction is coordinated along the width direction of the hopper 101 to avoid interference between the two during rotation, ensuring that the loading and unloading stages can operate independently and smoothly. At the same time, the first rotating shaft 104 and the second rotating shaft 105 extend along the width direction to adapt to the shape of the top opening of the hopper 101, so that the loading cover plate 1021 and the unloading cover plate 1022 can more tightly cover the top opening of the hopper 101 when closed, enhancing the sealing effect and further improving the anti-leakage performance of the loading vehicle 100 during the transfer process, taking into account structural stability, action coordination and sealing reliability.

[0032] Among them, the support base 103 serves as the mounting base for the loading cover plate 1021 and the unloading cover plate 1022. It spans across the top opening of the hopper 101 and extends along the width direction of the top opening of the hopper 101.

[0033] The loading cover 1021 is connected to one side of the support base 103 via the first rotating shaft 104, and the unloading cover 1022 is connected to the other side of the support base 103 via the second rotating shaft 105. The two are located on both sides of the support base 103 as the intermediate carrier, forming a symmetrical or corresponding distribution.

[0034] Specifically, the axes of the first rotating shaft 104 and the second rotating shaft 105 are parallel and both are arranged along the width direction of the top opening of the hopper 101, so that the rotation axes of the loading cover 1021 and the unloading cover 1022 are in the same direction and both rotate around the axis along the width direction of the opening. Based on this, when the loading cover 1021 is opened, it rotates towards one side of the support base 103, and when the unloading cover 1022 is opened, it rotates towards the other side of the support base 103. The support base 103 provides a stable mounting point, and the parallel and unidirectional rotating shaft layout ensures that the rotation trajectories of the loading cover 1021 and the unloading cover 1022 do not interfere with each other. They can independently complete the opening or closing action, and when closed, they can tightly cover the top opening of the hopper 101 together to ensure a sealing effect. At the same time, they adapt to the shape characteristics of the opening, so that the rotation action of the loading cover 1021 and the unloading cover 1022 is more in line with the structural dimensions and operational requirements of the hopper 101.

[0035] In the above embodiments, see Figure 1 As shown, both the loading cover plate 1021 and the unloading cover plate 1022 have a fastening part 106 at their free ends, and the fastening part 106 is fastened to the outer edge of the top opening of the hopper 101.

[0036] Here, the free ends of the loading cover 1021 and the unloading cover 1022 are provided with a fastening part 106, which fastens to the outer edge of the top opening of the hopper 101. The fastening structure can enhance the tightness of the connection between the loading cover 1021 and the unloading cover 1022 and the hopper 101. On the one hand, it can eliminate the gap between the two, further enhance the sealing effect, effectively prevent the material from being scattered from the gap due to bumps and airflow during the transfer process, reduce material waste and prevent dust pollution. On the other hand, it can firmly fix the cover in the closed position, avoid the cover from being accidentally opened due to vibration during transportation, ensure the stability of the closed state of the hopper 101, and prevent the material from accidentally falling and causing safety hazards. It is suitable for long-term high-frequency operation needs and takes into account the sealing reliability, structural stability and operational safety.

[0037] The free ends refer to the ends of the loading cover 1021 and the unloading cover 1022 that can be freely rotated and moved, that is, the end of the loading cover 1021 that is not connected to the support base 103 via the first rotating shaft 104, and the end of the unloading cover 1022 that is not connected to the support base 103 via the second rotating shaft 105. In this embodiment, both the loading cover 1021 and the unloading cover 1022 have three free ends.

[0038] The fastening part 106 can be a flange, hook, or folded edge, etc., as long as it can form a mechanical fit with the outer edge of the top opening of the hopper 101. This application does not limit this.

[0039] Specifically, when the loading cover plate 1021 and the unloading cover plate 1022 are in the closed state, the fastening part 106 at the free end of both will fasten to the outer edge of the top opening of the hopper 101, so that the loading cover plate 1021 and the unloading cover plate 1022 form a tight mechanical connection with the edge of the opening of the hopper 101. This not only restricts the displacement of the loading cover plate 1021 and the unloading cover plate 1022 in the closed state, but also reduces the gap between them through the fit of the fastening surfaces, thereby enhancing the sealing effect and the stability of the closed state.

[0040] Further, see Figure 2 As shown, in order to illustrate the working process of the feeding car 100 in actual production, the embodiments of this application also provide a lime kiln feeding system, including the feeding car 100 of any of the above and the elevator 200; the feeding car 100 is detachably or fixedly mounted on the elevator 200; the elevator 200 is used to drive the feeding car 100 to rise and fall in the vertical direction, so as to realize the transfer of materials from the low loading area to the top unloading area of ​​the lime kiln.

[0041] In this embodiment, after the loading trolley 100 completes loading in the low-level loading area, the sealing cover 102 is closed to prevent material from scattering. Subsequently, the elevator 200 drives the loading trolley 100 to rise vertically, transporting the material to the unloading area at the top of the lime kiln. Upon arrival, the loading trolley 100 can unload the material by automatically opening the unloading cover 1022. During this process, the sealing cover 102 ensures the cleanliness and efficiency of material transfer.

[0042] The hoist 200 can be a chain hoist 200, a wire rope hoist 200, or a guide rail hydraulic hoist 200, etc., and this application does not limit it.

[0043] In the above embodiments, see Figure 1 and Figure 2As shown, when the sealing cover 102 includes a loading cover plate 1021 and a unloading cover plate 1022, the lime kiln feeding system also includes an opening and closing rope 300; one end of the opening and closing rope 300 is connected to the loading cover plate 1021, and the other end is fixed relative to the support frame of the elevator 200; the opening and closing rope 300 is configured such that: when the elevator 200 drives the feeding car 100 to descend to the low loading area, the opening and closing rope 300 is pulled by the relative displacement between the feeding car 100 and the support frame, thereby driving the loading cover plate 1021 to rotate around the first rotating shaft 104 to open; when the elevator 200 drives the feeding car 100 to rise, the pulling force of the opening and closing rope 300 is weakened or disappears, and the loading cover plate 1021 rotates in the opposite direction around the first rotating shaft 104 to close under its own gravity.

[0044] Here, the opening and closing action of the loading cover 1021 is strongly linked with the lifting action of the loading car 100, forming a linkage mechanism that opens when lowering and closes when rising. This avoids delays or oversights in manual operation, ensuring that the loading cover 1021 opens in a timely manner during the loading stage without affecting the loading efficiency, and that the loading cover 1021 closes automatically during the transfer stage to ensure a seal and prevent leakage, thus reducing the risk of material waste or contamination caused by human error.

[0045] Among them, the opening and closing rope 300 can be a high-strength flexible rope such as steel wire rope or wear-resistant nylon rope.

[0046] Specifically, one end of the opening / closing rope 300 is fixedly connected to the free end or near the free end of the loading cover plate 1021, ensuring that it can efficiently drive the loading cover plate 1021 to rotate around the first rotating shaft 104 when pulled. The other end is fixed to the support frame of the elevator 200, such as the fixed column or crossbeam of the elevator 200, forming a relatively stationary fulcrum. Based on this, when the elevator 200 drives the loading cart 100 to descend from the high position to the low position loading area, a relative displacement occurs between the loading cart 100 and the fixed support frame. For example, if the loading cart 100 moves downward and the support frame remains stationary, the opening / closing rope 300 will be gradually stretched and pulled. Since one end of the opening and closing rope 300 is fixed to the support frame and the other end is connected to the loading cover plate 1021, the pulling force will cause the loading cover plate 1021 to rotate around the first rotating shaft 104 in a direction away from the opening of the hopper 101. If it flips upward, the loading cover plate 1021 will eventually be in the open state, at which time the top opening of the hopper 101 will be open, and materials can be loaded. When the loading is completed, when the elevator 200 drives the loading trolley 100 to rise from the low loading area to the high unloading area, the relative displacement direction of the loading trolley 100 and the support frame is opposite. The loading trolley 100 moves upward and gradually approaches the fixing point of the opening and closing rope 300. The pulling force of the opening and closing rope 300 gradually weakens until it disappears. At this time, the loading cover plate 1021 loses its pull and rotates in the opposite direction around the first rotating shaft 104 under its own gravity. If it flips downward, it will eventually return to the closed state, and the fastening part 106 at its free end will fasten with the outer edge of the top opening of the hopper 101 to achieve a seal.

[0047] It should be noted that, in order to ensure that the opening and closing rope 300 can generate sufficient pulling stroke to drive the loading cover 1021 to fully open when the loading car 100 descends to the low loading area, and to prevent the opening and closing rope 300 from getting tangled or interfering due to excessive slack when the loading car 100 rises to the high unloading area, the connection point between the opening and closing rope 300 and the support frame of the hoist 200 must be located in the upper middle part of the support frame. When the connection point is in the upper region of the support frame, during the process of the loading trolley 100 descending from the high position to the low position loading area, the change in length of the opening and closing rope 300, i.e. the pulling stroke, can meet the requirement of the loading cover 1021 rotating around the first rotating shaft 104 to the fully open state. When the loading trolley 100 rises to the high position unloading area, the distance between the loading trolley 100 and the connection point is shortened, and the opening and closing rope 300 is in a moderately slack state, rather than excessively drooping. This can ensure that the loading cover 1021 can be reliably closed under its own weight, and can also avoid interference problems such as the rope getting tangled or stuck with other parts of the loading trolley 100 or the running trajectory of the hoist 200 due to excessive drooping. This improves the opening effectiveness during the loading stage and the structural safety during the transfer and unloading stages.

[0048] In the above embodiments, see Figure 1As shown, the upper surface of the loading cover plate 1021 away from the first rotating shaft 104 is provided with a hanging ear 107, which is used to thread and fix the end of the opening and closing rope 300.

[0049] Here, the lug 107 provides a stable connection point between the opening / closing rope 300 and the loading cover 1021. Simultaneously, the lug 107 is positioned on the upper surface away from the first rotating shaft 104, maximizing the lever arm of the opening / closing rope 300 during pulling. This allows for efficient rotation of the loading cover 1021 around the first rotating shaft 104 with minimal pulling force, ensuring smooth and effortless opening of the loading cover 1021. Furthermore, the lug 107 facilitates quick threading, fixing, and subsequent maintenance and replacement of the opening / closing rope 300, preventing loosening or detachment of the rope connection. This ensures the reliability of the linkage mechanism between the opening / closing rope 300 and the loading cover 1021, thereby guaranteeing that the loading cover 1021 automatically opens and closes as expected during lifting and lowering.

[0050] In the above embodiments, see Figure 2 and Figure 3 As shown, the elevator 200 also includes a conveying guide rail; the conveying guide rail is fixedly installed on the support frame and extends along the lifting direction of the elevator 200; the top section of the conveying guide rail forms a tilting section, which is an arc-shaped guide rail that tilts towards the inside of the lime kiln; when the feeding car 100 moves to the tilting section under the drive of the elevator 200, the feeding car 100 tilts along the trajectory of the arc-shaped guide rail, so as to drive the hopper 101 to tilt synchronously.

[0051] Here, the conveyor rail not only provides stable guidance for the lifting and lowering of the feeding trolley 100, ensuring the smoothness of its vertical movement, but also allows the feeding trolley 100 to automatically tilt along the arc-shaped guide rail trajectory when it moves to the tilting section at the top into the lime kiln, thereby driving the hopper 101 to tilt synchronously. Unloading can be completed without additional drive devices, simplifying the unloading process and equipment structure. At the same time, the arc-shaped guide rail ensures that the tilting angle of the hopper 101 is consistent and the unloading position is accurate, avoiding material spillage or incomplete unloading. This not only improves unloading efficiency and reliability, but also reduces material waste and pollution to the surrounding environment of the lime kiln.

[0052] The main body of the conveying guide rail is an inclined guide rail, i.e., an inclined section. In this embodiment, the top of the inclined section is the tilting section.

[0053] The tilting section is the end section at the top of the conveyor rail. It has an arc-shaped rail structure that can smoothly transition with the main body of the rail without any obvious jamming or protrusion. This ensures that the loading car 100 can smoothly switch from the lifting state to the tilting state, avoiding material spillage or equipment impact due to sudden changes in trajectory.

[0054] Specifically, the bottom of the loading trolley 100 is equipped with guide components, such as rollers and sliders, that match the conveying guide rail. These guide components can slide or roll along the track of the conveying guide rail, reducing frictional resistance and ensuring that the loading trolley 100 strictly follows the guide rail trajectory and does not deviate from the track. In practical applications, when the elevator 200 drives the loading trolley 100 to move from the low-level loading area to the high-level unloading area, the guide components at the bottom of the loading trolley 100 slide along the inclined section of the conveying guide rail. The inclined guide rail provides guidance for the loading trolley 100, ensuring its stability during lifting and lowering and preventing material leakage from the hopper 101 due to shaking. When the loading trolley 100 moves to the top of the conveying guide rail and reaches the starting position of the tilting section, the guide components begin to enter the curved path along the arc-shaped guide rail. Afterward, the loading trolley 100 continues to move along the arc-shaped guide rail, with the tilt angle gradually increasing until it reaches the preset maximum tilting angle. This maximum tilting angle ensures that the material in the hopper 101 can be completely unloaded.

[0055] In the above embodiment, when the hopper 101 tilts with the loading car 100, the unloading cover 1022 rotates and opens around the second rotating shaft 105 under the pressure of the material's gravity or the inertia of the hopper 101 tilting, so that the material in the hopper 101 can be unloaded into the lime kiln.

[0056] Here, when the hopper 101 tilts towards the lime kiln side along with the loading car 100, the material inside the hopper 101 will gather and flow in the tilting direction of the hopper 101, i.e., the discharge direction, under the action of gravity. This will eventually generate a continuous squeezing force on the inner side of the discharge cover 1022, which is used to open the discharge cover 1022. In addition, after the hopper 101 enters the arc-shaped guide rail with the loading car 100, it will have an inertial force in the discharge direction. This inertial force will cause the material inside the hopper 101 and the discharge cover 1022 itself to move in the discharge direction, further assisting the opening of the discharge cover 1022.

[0057] In the above embodiment, when the hopper 101 tilts with the loading trolley 100, the loading cover 1021 is kept closed by the continuous pulling of the opening and closing rope 300.

[0058] Here, the opening and closing rope 300 remains taut as the loading trolley 100 moves to the tipping section. This prevents the loading cover 1021 from affecting the opening of the unloading cover 1022, ensuring an unobstructed unloading process.

[0059] Specifically, in this embodiment, one end of the opening and closing rope 300 is fixed to the upper middle area of ​​the support frame of the elevator 200, and the other end is connected to the loading cover plate 1021. When the loading car 100 moves to the tilting section at the top of the conveying guide rail, its position is close to the upper part of the support frame. At this time, although the distance between the loading car 100 and the fixing point of the opening and closing rope 300 is slightly closer than during the ascent, the opening and closing rope 300 can still maintain a certain tension, rather than being completely slack. This allows the loading cover plate 1021 to remain closed under the pulling force of the opening and closing rope 300, and the fastening part 106 at its free end will continue to fasten with the outer edge of the opening of the hopper 101, forming a reliable seal. Based on this, it can prevent some material from leaking out from the gap on one side of the loading cover plate 1021 when the hopper 101 tilts and unloads, ensuring that all material can be unloaded into the lime kiln from the unloading cover plate 1022 side, reducing waste and pollution.

[0060] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0061] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
