Description

Technical Field

[0001] The present invention relates to the technical field of bulk-to-container loading, and in particular to a vertically descending, impact-proof bulk-to-container loading device and a loading method. Background Art

[0002] Bulk-to-container transport is a mode of transport that loads traditional bulk cargoes such as coal, coke, and bauxite into containers for multimodal transport, achieving seamless connection of the transport chain through standardized loading. This mode of transport can effectively reduce environmental pollution and cargo damage accidents, and improve reliability and economy. Currently, this model is widely used in port and railway transportation, and has become an important measure to promote the upgrading of bulk commodity transportation.

[0003] The following problems have been found in the exploration and operation of the bulk-to-container transport mode: (1) Reference Figure 1 and Figure 2 The bulk-to-container loading device includes a buffer silo 1 and a telescopic chute 2 mounted at its bottom. After bulk cargo is unloaded from a truck, it is first transferred to the elevated buffer silo 1 via a belt conveyor. A container 3 is placed beneath the buffer silo 1. A tilting machine 4 flips the container 3 (with its door facing upward and open during loading). The telescopic chute 2 then descends and extends into the container 3, allowing the buffer silo 1 to load the material into the container 3 via the telescopic chute 2. Since the distance H from the buffer silo 1 to the bottom of the container 3 is usually as high as 10 to 15 meters, after the material drops from the buffer silo 1 along the telescopic chute 2 to the container 3, it will generate a large impact force due to the influence of the drop factor. On the one hand, this impact force will cause certain impact damage to the container body, and on the other hand, it will cause serious impact damage to the material (such as coke), resulting in a significant increase in the breakage rate of coke in the bulk to container transfer link, greatly affecting the quality of the product; at present, in order to solve the problem of easy breakage of coke during the unloading process, some companies usually use the self-swing of the telescopic chute, the bending of part of the chute, or add a buffer bucket to the chute to slow down the speed of the vertical unloading. However, these buffering methods will greatly reduce the loading efficiency on the one hand, and on the other hand, they will still be affected by the material drop and inevitably cause impact damage. Therefore, the problem of easy breakage of coke in the bulk to container loading process has been difficult to effectively and properly solve. (2) References Figure 2 In order to prevent dust pollution caused by the materials falling from the telescopic chute 2 into the box, a dust-proof skirt 5 is usually installed at the tail end of the telescopic chute 2. During loading, the dust-proof skirt 5 is extended into the box along with the telescopic chute 2. When the telescopic chute 2 is lifted and recovered, the dust-proof skirt 5 needs to move up and down in the box along with the telescopic chute 2. This dynamic dust-proof method is not sealed tightly, which will cause dust to overflow during the unloading process, easily causing pollution to the surrounding working environment. Summary of the Invention

A pre-storage material buffer space for pre-storage materials is formed between the pre-storage material buffer mechanism and the discharge valve, and the pre-storage material buffer mechanism is connected to an opening and closing drive mechanism; A limiting sleeve is installed on the upper part of the pre-storage box sleeve, a sealing cover plate is placed on the upper part of the limiting sleeve, a slide pipe through hole is provided on the sealing cover plate, the telescopic slide pipe passes through the sealing cover plate, and the sealing cover plate is slidably matched with the telescopic slide pipe; A material level meter is installed on the pre-storage box sleeve, and a signal output end of the material level meter is connected to a controller; the pre-storage box sleeve is connected to a lifting drive mechanism, and the controller controls the lifting drive mechanism, and the lifting drive mechanism drives the pre-storage box sleeve and the telescopic chute to rise and fall.

[0006] As a preferred technical solution, a protective frame is fixedly installed on the outer side of the pre-storage box sleeve, and the pre-storage buffer mechanism is located inside the protective frame when in a closed state.

[0007] As a preferred technical solution, a sealing strip is provided around the periphery of the sealing cover plate.

[0008] As a preferred technical solution, a dustproof skirt is provided on the lower part of the sealing cover plate, located on the inner side of the sealing strip.

[0009] As a preferred technical solution, a sealing sleeve is provided above the sealing cover plate at the slide pipe through hole.

[0010] As an optimal technical solution, the pre-storage material buffer mechanism includes two oppositely arranged fan-shaped plates, a buffer plate is arranged between the bottoms of the two fan-shaped plates, a material baffle plate is arranged on the outside of the buffer plate, and an avoidance groove for avoiding the pre-storage material box sleeve is formed above the material baffle plate; a gear for meshing transmission is arranged at the top of the fan-shaped plate.

[0012] As a preferred technical solution, the lifting drive mechanism includes a driving motor, a turntable, a pulley and a steel wire rope, and the steel wire rope passes through the sealing cover plate and is connected to the pre-storage box sleeve.

[0013] As a preferred technical solution, the opening and closing drive mechanism is an oil cylinder.

[0014] The present invention also provides a loading method using the vertical drop type impact-proof bulk loading device, comprising the following steps: S1. Preparation: Place the container at the set position below the buffer silo, turn the container over so that the door faces upward and opens, the telescopic chute is at the upper limit, and the discharge valve and pre-storage buffer mechanism of the buffer silo are closed; S2. Pre-storage buffer operation: First, keep the telescopic chute at the upper limit state, open the discharge valve of the buffer silo, and allow the bulk materials in the buffer silo to enter the pre-storage buffer space formed when the telescopic chute is at the upper limit state; then control the telescopic chute to descend, and the telescopic chute descends with the bulk materials. As the telescopic chute descends, the pre-storage buffer space continues to expand and is continuously filled with bulk materials; S3. Bulk-to-Container Loading Operation: When the telescopic chute carrying the bulk materials descends to the lower limit, the chute section at the end of the telescopic chute approaches the bottom of the container, and the sealing cover is closed at the top opening of the container; the pre-storage buffer mechanism is opened, and the bulk materials in the pre-storage buffer space begin to be unloaded into the container; as the bulk materials in the pre-storage buffer space are unloaded, the bulk materials in the buffer silo continue to enter the pre-storage buffer space; during the loading process, the material level meter monitors the material level in the container in real time, and the telescopic chute rises synchronously with the rising material level; S4. Reset after loading is completed: When the material in the container reaches the preset weight value or material level, the discharge valve of the buffer silo is closed, the telescopic chute rises to the upper limit, the pre-storage material buffer mechanism is closed, and the bulk material conversion to container operation is completed.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: (1) The present invention innovatively proposes for the first time the use of a pre-storage buffer unloading method, by fixing a pre-storage box sleeve on the chute pipe section at the end of the telescopic chute, and installing an openable and closable pre-storage buffer mechanism on the pre-storage box sleeve, and forming a pre-storage buffer space for pre-storage materials between the pre-storage buffer mechanism and the unloading valve. In this way, during the bulk-to-container loading operation, the bulk materials can be unloaded into the pre-storage buffer space first, and then the telescopic chute is lowered to carry the bulk materials in the pre-storage buffer space and loaded into the container, changing from the traditional high-level impact unloading to the pre-storage sequential buffer unloading. The entire loading process of the bulk materials from the buffer silo along the telescopic chute to the container is continuous and impact-free unloading is achieved due to the pre-storage buffer, and no impact force is generated due to the drop factor, thereby greatly reducing the breakage rate of the bulk materials (especially coke), and effectively avoiding impact damage to the container body, and at the same time will not affect the loading efficiency.

[0016] (2) By utilizing the limiting sleeve on the upper part of the pre-storage box sleeve, the matching mode of the telescopic chute and the sealing cover is changed, so that the sealing cover and the telescopic chute can be slidably matched. In this way, when the telescopic chute is lowered, when the sealing cover is in contact with the container body, the sealing cover can naturally cover the top box opening of the container to achieve static sealing; and during the loading process, when the telescopic chute is lifted, the sealing cover will not follow the chute to rise and move in the box body, thereby preventing dust from overflowing during the unloading process, and the dust prevention effect is significantly improved; when the loading is completed, as the telescopic chute continues to be lifted and recovered, the sealing cover will eventually be separated from the top box opening position of the container under the support of the limiting sleeve and return to its initial state. The structural design is ingenious and easy to operate and use.

[0017] (3) When the telescopic chute is at the upper limit and the pre-storage buffer mechanism is closed, the bulk material can be effectively buffered and pre-stored; when the telescopic chute descends and the pre-storage buffer mechanism is opened for unloading, it does not affect the vertical discharge speed of the bulk material and does not affect the loading efficiency; the structural design is unique, the operation is flexible and reliable, and there will be no jamming.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0021] like Figures 3 to 6 As shown, the vertical drop-type impact-proof bulk-to-collect loading device includes a buffer silo 1, which is installed at a high position and is used to store bulk materials transferred from a belt conveyor; a discharge valve 6 is installed at the discharge port of the buffer silo 1, and the discharge valve 6 is preferably a flat gate valve, preferably a hydraulic flat gate valve. Of course, other drive modes can also be used, which should all fall within the scope of protection of the present invention; the discharge port of the discharge valve 6 is connected to the telescopic chute 2, and of course the telescopic chute 2 includes two or more chute pipe sections arranged in sequence, which is a well-known structure and will not be described in detail here; refer to Figure 7 and Figure 8 A pre-storage material box sleeve 7 is fixedly installed on the chute pipe section at the end of the telescopic chute 2, and an openable and closable pre-storage material buffer mechanism 8 is installed on the pre-storage material box sleeve 7. A pre-storage material buffer space 9 for pre-storage material is formed between the pre-storage material buffer mechanism 8 and the discharge valve 6. The pre-storage material buffer mechanism 8 is connected to an opening and closing drive mechanism 16. The opening and closing drive mechanism 16 preferably adopts an oil cylinder, which works stably and reliably. Figure 5 、 Figure 6 and Figure 8 When the telescopic chute 2 is at the upper limit, the discharge valve 6 and the pre-storage buffer mechanism 8 of the buffer silo 1 are in the closed state; during the bulk-to-container loading operation, the discharge valve 6 is opened, and the bulk materials are first unloaded into the pre-storage buffer space 9, and then the telescopic chute 2 descends to carry the bulk materials in the pre-storage buffer space 9 and load them into the container. In this way, the traditional high-position impact unloading is changed to the pre-storage sequential buffer unloading. The entire loading process of the bulk materials from the buffer silo 1 along the telescopic chute 2 to the container is continuous and impact-free unloading is achieved due to the pre-storage buffer. There is no impact force generated by the drop factor, which greatly reduces the breakage rate of the bulk materials (especially coke) and effectively avoids impact damage to the box body without affecting the loading efficiency.

[0022] Refer again Figure 7 and Figure 8In this embodiment, the pre-storage buffer mechanism 8 comprises two sets of cooperating gate structures, each of which includes two opposing sector plates 81. An arc-shaped buffer plate 82 is positioned between the bottoms of the two sector plates 81. A material retaining plate 83 is positioned on the outside of the buffer plate 82, and a clearance groove 84 is formed above the material retaining plate 83 to allow the pre-storage box sleeve 7 to be cleared during rotation. A gear 85 for meshing transmission is positioned at the top of the sector plates 81. This allows the opening and closing drive mechanism 16 to drive the gate structure on one side to rotate synchronously with the gear 85 on the gate structure, thereby achieving the opening and closing of the two gate structures. This unique structural design ensures flexible and reliable operation, and prevents jamming during opening and unloading.

[0023] refer to Figure 9 The buffer plate 82 comprises a base plate 821 with protruding retaining ribs 822 protruding from it. An elastic plate 823 is secured to the retaining ribs 822. The elastic plate 823 is made of a rubber elastic material and is easily replaceable through its secure connection. When the telescopic chute 2 is in the upper limit position, the pre-storage buffer mechanism 8 is closed. When the discharge valve 6 of the buffer silo 1 is opened, the bulk material falls from the limited height of the buffer silo 1 onto the elastic plate 823. This not only avoids the impact force generated by the large drop, but also, due to the elastic cushioning effect, significantly reduces the breakage rate of the bulk material (particularly coke) and effectively prevents impact damage to the tank.

[0024] refer to Figure 6 and Figure 8 A limiting sleeve 15 is installed on the upper part of the pre-storage box sleeve 7, and a sealing cover plate 10 is placed on the upper part of the limiting sleeve 15. The cover size of the sealing cover plate 10 is larger than the box opening size of the container. A slide pipe through hole is provided on the sealing cover plate 10, and the telescopic slide pipe 2 passes through the sealing cover plate 10. The sealing cover plate 10 is slidably matched with the upper pipe section of the telescopic slide pipe 2; Figures 12 to 16 By utilizing the limiting sleeve 15 on the upper part of the pre-storage box sleeve 7, the matching mode of the telescopic chute 2 and the sealing cover plate 10 is changed, so that the sealing cover plate 10 and the telescopic chute 2 are slidably matched. In this way, when the telescopic chute 2 is descending, after the sealing cover plate 10 abuts against the box body of the container 3, the sealing cover plate 10 can naturally cover the top box opening of the container 3 to achieve static sealing; and in the loading process, when the telescopic chute 2 is lifted, the sealing cover plate 10 will not follow the chute to rise and move in the box body, thereby not causing dust to overflow during the unloading process, and the dust prevention effect is significantly improved; when loading is completed, as the telescopic chute 2 continues to be lifted and recovered, the sealing cover plate 10 will eventually break away from the top box opening position of the container 3 under the support of the limiting sleeve 15 and return to its initial state. The structural design is ingenious and easy to operate and use.

[0025] In this embodiment, a sealing strip is provided around the perimeter of the sealing cover plate 10. A sealing sleeve 14 is provided above the sealing cover plate 10, located at the chute through-hole. A dust-proof skirt 5 is provided below the sealing cover plate 10, located inside the sealing strip. When the sealing cover plate 10 is closed over the top opening of the container 3, the upper portion is sealed by the sealing sleeve 14, while the lower portion is double-sealed by the sealing strip and the dust-proof skirt 5, effectively preventing dust from escaping.

[0026] refer to Figure 6 The pre-storage box sleeve 7 is equipped with a material level meter 11, and the signal output end of the material level meter 11 is connected to the controller; the pre-storage box sleeve 7 is connected to a lifting drive mechanism 12, and the controller controls the connection to the lifting drive mechanism 12. During the loading process, the lifting drive mechanism 12 can drive the pre-storage box sleeve 7 and the telescopic chute 2 to rise and fall according to the material level. The material level meter 11 is preferably a radar level meter. Figure 4 The lifting drive mechanism 12 includes a drive motor 121, a turntable 122, a pulley 123, and a steel wire rope 124. The steel wire rope 124 passes through the sealing cover plate 10 and is connected to the pre-storage box sleeve 7. The drive motor 121 is connected to the turntable 122 via a reducer. The turntable 122 is equipped with an encoder that converts angular displacement into an electrical signal to achieve displacement control during the lifting and lowering process of the telescopic chute. When the telescopic chute reaches the upper or lower limit, the drive motor 121 automatically stops.

[0027] In this embodiment, a protective frame 13 is fixedly installed on the outside of the pre-storage box sleeve 7. When the pre-storage buffer mechanism 8 is in the closed state, it is located inside the protective frame 13. By providing the protective frame 13, it can play a protective role during the transportation of the equipment and avoid damage to the pre-storage buffer mechanism.

[0028] refer to Figures 10 to 16 The method of converting scattered data into assembled data includes the following steps: S1. Preparation: Figure 10 As shown, the container 3 is placed at a set position below the buffer silo 1, and the container 3 is turned over by the turning machine 4 so that the door is facing upward and opened, the telescopic chute 2 is in the upper limit position, and the discharge valve 6 and the pre-storage buffer mechanism 8 of the buffer silo 1 are in the closed state; S2, pre-storage buffer operation: reference Figure 12 First, keep the telescopic chute 2 in the upper limit state, open the discharge valve 6 of the buffer silo 1, and allow the bulk material in the buffer silo 1 to enter the pre-storage buffer space 9 formed when the telescopic chute 2 is in the upper limit state. In this way, when the telescopic chute 2 is in the upper limit state and the pre-storage buffer mechanism 8 is closed, effective buffering and pre-storage of bulk material can be achieved; refer to Figure 13, continue to keep the pre-storage material buffer mechanism 8 closed, control the telescopic chute 2 to descend, and the telescopic chute 2 carries the bulk material downward while descending. At this time, the pre-storage buffer space 9 continues to expand as the telescopic chute 2 descends and is continuously filled with bulk material and extends to the bottom of the box; S3. Bulk to container loading operation: Reference Figure 14 When the telescopic chute 2 carrying the bulk materials descends to the lower limit, the chute section at the end of the telescopic chute 2 approaches the bottom of the container 3 (0.5 to 1.5 meters from the bottom of the container), and the sealing cover 10 covers the top opening of the container 3; at this time, the pre-storage buffer mechanism 8 is opened, and the bulk materials in the pre-storage buffer space 9 begin to be discharged into the container 3; as the bulk materials in the pre-storage buffer space 9 are unloaded, the bulk materials in the buffer silo 1 continue to enter the pre-storage buffer space 9; when the pre-storage buffer mechanism 8 is opened to discharge, it does not affect the descending speed of the bulk materials and will not affect the loading efficiency. Figure 15 During the loading process, the material level in the container 3 is monitored in real time by the material level meter 11. The telescopic chute 2 rises synchronously with the material level, and the telescopic chute 2 is controlled to maintain a distance of 0.5 meters from the material. S4, reset after loading: reference Figure 16 When the material in the container 3 reaches the preset weight value or material level, the discharge valve 6 of the buffer silo 1 is closed, the telescopic chute 2 rises to the upper limit, and the pre-storage material buffer mechanism 8 is closed to complete the bulk-to-container conversion operation.

[0029] In summary, the present invention innovatively proposes for the first time the use of a pre-storage buffer unloading method for bulk-to-container loading operations. A pre-storage box sleeve is fixedly installed on the chute pipe section at the end of the telescopic chute, and an openable and closable pre-storage buffer mechanism is installed on the pre-storage box sleeve. A pre-storage buffer space for pre-stored materials is formed between the pre-storage buffer mechanism and the unloading valve. During the bulk-to-container loading operation, the bulk materials can be first unloaded into the pre-storage buffer space, and then the telescopic chute is lowered to carry the bulk materials in the pre-storage buffer space and load them into the container. In this way, the traditional high-level impact unloading is changed to pre-storage sequential buffer unloading. The bulk materials are continuously unloaded from the buffer silo along the telescopic chute to the container, and due to the pre-storage buffer, the entire loading process is continuous and impact-free due to the pre-storage buffer. There is no impact force generated by the height difference, which greatly reduces the breakage rate of bulk materials (especially coke) and effectively avoids impact damage to the container body without affecting the loading efficiency.

[0030] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
