Description

Technical Field

[0001] This invention belongs to the field of material handling equipment technology, and particularly relates to a vehicle-mounted material compaction device. Background Technology

[0002] In existing technologies, most materials are applied directly in granular form. If granular materials are difficult to transport and need to be formed into block structures during use, the transportation of granular materials before construction is costly and prone to scattering, resulting in additional processes such as collection and treatment of scattered materials.

[0003] In existing technologies, for some contaminated soil, other polluting particles, or radioactive particles, they can be compacted into blocks and then buried to treat particulate pollutants or radioactive materials and reduce air pollution. However, the entire compaction process is cumbersome and requires the coordinated use of multiple structures, resulting in a large space occupation and high cost for the entire equipment system. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle-mounted material compaction device, which integrates multiple units into a vehicle body, thereby completing compaction and shrinkage simultaneously within a single vehicle-mounted device, thus forming a solid block structure and completing the compaction process.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0006] The vehicle-mounted material compaction device includes the vehicle cab and also includes...

[0007] Body assembly, and a passenger compartment assembly located on the body assembly, wherein an assembly platform is formed on the passenger compartment assembly;

[0008] From the front of the vehicle to the body assembly, the assembly platform is sequentially equipped with a PE film heat shrink oven, a compaction unit, a hopper, and a mixing unit. The mixing unit is connected to the lifting assembly below the hopper via a first transmission unit, and the compaction assembly moves along the bottom of the hopper via a second transmission unit.

[0009] The PE film heat shrink oven is connected to the compaction assembly through a third transmission unit passing through the PE film heat shrink oven. A fourth transmission unit is provided on the side of the PE film heat shrink oven, which is parallel to the third transmission unit and moves in the opposite direction. The two ends of the fourth transmission unit are connected to the third transmission unit through a first pushing unit and a second pushing unit with opposite working directions, respectively.

[0010] As a further improvement of the present invention, it also includes a lifting platform located near the front of the vehicle, wherein a weighing unit is provided on the lifting platform, and a fifth transmission unit is located between the lifting platform and the mixing unit.

[0011] As a further improvement of the present invention, the lifting platform is a scissor lift platform, including a worktable, a double scissor lifting assembly and a base, with a material leakage assembly disposed between the worktable and the base, and the fifth transmission unit located at the bottom of the material leakage assembly.

[0012] As a further improvement of the present invention, the stirring unit includes a feed hopper, and the fifth transmission unit is mounted on the feed hopper.

[0013] As a further improvement of the present invention, the vehicle body assembly includes a first vehicle body and a second vehicle body, the mixing unit is located on the first vehicle body, the PE film heat shrink furnace, the compaction unit and the hopper are located on the second vehicle body, the hopper is connected to the first transmission unit via a downward inclined track, and the first transmission unit located on the first vehicle body is connected to the second vehicle body.

[0014] As a further improvement of the present invention, a rotating shaft is provided on the first vehicle body, the first transmission unit is located on the rotating shaft, and the width of the transmission cavity formed by the first transmission unit is greater than the width of the transmission cavity formed by the inclined track.

[0015] As a further improvement of the present invention, the compaction unit includes a mold assembly and a transfer unit that moves along the mold assembly and is located between the mold assembly and the hopper. The transfer unit moves horizontally above the mold assembly under the action of a second transmission unit composed of a cylinder assembly.

[0016] As a further improvement of the present invention, the mold assembly includes a lower mold with a receiving cavity and an upper mold that is matched with the lower mold and has a vibration assembly. The lower mold has a plurality of forming cavities, and a cylinder lifting assembly is provided at the bottom of the lower mold.

[0017] As a further improvement of the present invention, a cutting mechanism is also included, located between the compaction unit and the PE film heat shrink oven. The cutting mechanism is a lifting cutting mechanism, and the lifting cutting mechanism is mounted on a mounting frame with the upper mold.

[0018] As a further improvement of the present invention, the lifting component is a belt assembly, which is mounted on the inclined surface of a triangular support frame with right angles, and the transmission width formed by the belt assembly is less than or equal to the transmission width of the second transmission unit.

[0019] The beneficial effects of this invention are as follows:

[0020] In this invention, the compaction unit, PE film heat shrink oven, and stirring unit are integrated together on a single vehicle body to form a compact device. Compared to a system composed of multiple components, it occupies less space and can be transported using the vehicle head. That is, by controlling the vehicle head, the entire device can be operated, making it suitable for compacting dispersed particulate materials.

[0021] In this invention, a compaction shrinkage device and a compaction unit are added, so that in the whole process, the particles are first pre-compacted by the compaction unit and then shrinked and compacted by the PE film heat shrink oven, so that the block structure formed after the particles are compacted is more stable.

[0022] In this invention, again, due to the multiple transmission units and pushing units in the compaction unit, the compacted and shrunken block structure is repeatedly compressed and compacted, and then repeatedly compressed. Compared with repeated compression in the compaction device, it can be compacted and shrunken after a certain transmission. The compacted block structure has a more uniform density and so on.

[0031] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0032] In this embodiment, the technical solution of the present invention will be described from the following aspects.

[0033] First, the core structure and core components of this invention.

[0034] See attached document Figure 1-6 As shown, the vehicle-mounted material compaction device of the present invention includes a front end 10 and a body assembly 20 connected to the front end 10, and a cargo box assembly 30 located on the body assembly 20, wherein an assembly platform is formed on the cargo box assembly 30.

[0035] The assembly sequence of the core components in this invention on the vehicle is as follows: from the front of the vehicle 10 to the body assembly 20, the assembly platform is sequentially equipped with a PE film heat shrink oven 100, a compaction unit 200, a hopper 300 and a stirring unit 400. The stirring unit 400 is connected to the lifting assembly 310 below the hopper 300 through a first transmission unit 410. The compaction assembly 200 moves along the bottom of the hopper 200 through a second transmission unit 210.

[0036] After compaction, in order to form a block and cover it, the PE film heat shrink oven 100 in this embodiment is connected to the compaction assembly 200 through a third transmission unit 110 passing through the PE film heat shrink oven 100. A fourth transmission unit 120 is provided on the side of the PE film heat shrink oven 100, which is parallel to the third transmission unit 110 and moves in the opposite direction. The two ends of the fourth transmission unit 120 are connected to the third transmission unit 110 through a first pushing unit 130 and a second pushing unit 140 with opposite working directions, respectively.

[0037] The working principle of this invention is as follows: using various transmission units, contaminated soil or other particles mixed by the stirring unit 400 are mixed with some auxiliary materials and water to form particles with a certain viscosity and moisture. Then, the mixture is stirred and then conveyed to the compaction unit 200 for compaction to form a block structure. Finally, a PE film heat shrink oven is used to perform film coating and shrinkage, thereby forming a coated and compacted material block, thus achieving compaction. The compaction device of this invention can be used for the treatment of contaminated soil, which can be compacted and filled into caves or other caverns to achieve the treatment of contaminated soil.

[0038] Secondly, this embodiment mainly introduces the detailed structure and positional relationship of each structure.

[0039] Referring to the accompanying drawings, in this embodiment, to add auxiliary materials, such as granite, cement, and water when treating contaminated soil, it is necessary to add some granite, cement, and water to mix with the contaminated soil to form particles with strength and hardness. Therefore, a lifting platform 500 is also included near the front of the vehicle 10. A weighing unit (not shown in the figure) is provided on the lifting platform 500, and a fifth transmission unit 510 is located between the lifting platform 500 and the mixing unit 400. In this embodiment, the purpose of adding a weighing unit is to directly measure the weight of the material on the lifting platform 500. Specifically, in this embodiment, a gravity sensor is directly added to the lifting platform 500, which can directly obtain the weight. The purpose of choosing a lifting platform is that when other materials are added, the height of their storage devices is uncertain. By adding a lifting platform, it is not necessary to move the storage units of other materials, which facilitates material retrieval. It can be installed on the vehicle body components for direct integration, saving space.

[0040] For ease of assembly, the lifting platform 500 is a scissor lift platform, including a workbench 520, a double-scissor lifting assembly 530, and a base 540. A material leakage assembly 550 is disposed between the workbench 530 and the base 540, and the fifth transmission unit 510 is located at the bottom of the material leakage assembly 550. In this embodiment, with this arrangement, when material leakage is required, a suitable weight of auxiliary material is first weighed using a weighing unit, and then the bottom opening of the material leakage assembly 550 is opened. The auxiliary material is then directly transferred towards the mixing unit 400 via the conveyor belt, in conjunction with the barrier formed by the double scissors. This process eliminates the need for separate weighing of the auxiliary material and can be directly implemented within this device.

[0041] To facilitate transport, especially of auxiliary materials, in this embodiment, the stirring unit 400 includes a feeding hopper, and the fifth transport unit 510 is mounted on the feeding hopper. In this embodiment, it is directly mounted without additional devices. A commonly used conveyor belt can be used to form the fifth transport unit, which is simple to assemble and easy to control.

[0042] Because this embodiment has many components, it is difficult to assemble them all in one vehicle body. Therefore, the vehicle body assembly 20 includes a first vehicle body 21 and a second vehicle body 22. The mixing unit 400 is located on the first vehicle body 21, and the PE film heat shrink oven 100, compaction unit 200, and hopper 300 are located on the second vehicle body 22. The hopper 300 is connected to the first transmission unit 410 via a downward-facing inclined rail 320. The first transmission unit 410, located on the first vehicle body 21, is connected to the second vehicle body 22. In this embodiment, the assembly of the two vehicle bodies is directly completed using a simple transmission unit. During transportation, the vehicle body is equipped with a separate cab, which can be used for independent long-distance direct transportation. In use, the transmission unit allows for direct and simple assembly, which is simple to operate and easy to implement.

[0043] In this embodiment, the first vehicle body 21 includes a first layer on the front side and a second layer below the first layer. The stirring unit 400, the rotating shaft 23 and the first transmission unit 410 are assembled on the lower second layer, while the lifting platform 500 is assembled on the first layer. Because the lifting platform needs to take into account weighing and material transportation, it is set higher. The stirring unit 400 needs to be transported to the other side later, so it can be set lower.

[0044] To further facilitate the connection between the vehicle bodies, a rotating shaft 23 is provided on the first vehicle body 21, and the first transmission unit 410 is located on the rotating shaft 23. The width of the transmission cavity formed by the first transmission unit 410 is greater than the width of the transmission cavity formed by the inclined track 320. In this embodiment, when the material enters the hopper from the mixing unit, the vertical transmission unit is wider and the horizontal transmission is stable, while the inclined track has a certain steepness and is therefore narrower.

[0045] Regarding the pelletizing device, specifically, the compaction unit 200 includes a mold assembly 220 and a transfer unit 230 that moves along the mold assembly 220 and is located between the mold assembly 220 and the hopper 300. The transfer unit 230 moves horizontally above the mold assembly 220 under the action of a second transmission unit 210 composed of cylinder assemblies. In this embodiment, the transfer unit 230 is used to transfer the material in the hopper to the mold assembly 220, and then the mold assembly 220 is used for corresponding compression molding to form a preliminary block structure.

[0046] In order to form a block-shaped soil embryo, the mold assembly 220 includes a lower mold 221 with a receiving cavity and an upper mold 222 that is matched with the lower mold 221 and has a vibration assembly. The lower mold 221 has a plurality of forming cavities, and the bottom of the lower mold 222 is provided with a cylinder lifting assembly. In this embodiment, a baffle is provided at the bottom of the transfer unit 230, allowing direct unloading from the hopper 300 into the transfer unit 230 at the bottom. The transfer unit 230 can unload by opening the baffle. In this embodiment, the baffle can also be a grid structure to achieve partial feeding. After partial feeding, the transfer unit 230 retracts to the hopper for the next feeding. At this time, the upper mold presses down for the first compaction. Then the transfer unit 230 feeds again, and the upper mold compacts again. This process is repeated to form a dense and relatively firm soil pellet. Furthermore, the same weight of particles, through repeated compaction, results in a smaller final volume, allowing for the storage of more contaminated soil or other materials while occupying less space.

[0047] To form a better block shape, or rather, a designed block shape, a cutting mechanism 600 is also included, located between the compaction unit 200 and the PE film heat shrink oven 100. The cutting mechanism 600 is a lifting cutting mechanism, and it is mounted on a mounting frame with the upper mold 222. In this embodiment, the cutting mechanism and the upper mold 222 are mounted on the same mounting frame, thus occupying less volume and requiring fewer components. It can also cut to the required size as needed, better meeting the requirements for the final stacking of contaminated soil blocks. Furthermore, this embodiment also includes a clamping mechanism 700, which is mounted on the same mounting frame as the cutting mechanism. The cutting mechanism 600 then cuts the product formed after the mold is removed according to requirements. The cut soil blocks are then clamped by the clamping mechanism onto the third transmission unit 110 for further transmission.

[0048] In this embodiment, during the compaction process, the loading unit 230 can move along the mold under the action of the cylinder, thereby entering or exiting the cavity formed by the mold. The mold assembly 220 body can also move horizontally along the second transmission unit 220 under the action of the cylinder. After the cutting is completed, the mold assembly moves towards the PE film heat shrink oven 100 along the second transmission unit 210. At this time, the clamping mechanism 700 located on the upper mold clamps the clay blank and is pushed forward under the action of the cylinder, and then placed on the third transmission unit 110.

[0049] To facilitate the lifting of the hopper, the lifting assembly 310 is a belt assembly, which is mounted on the inclined surface of a triangular support frame with right angles. The transmission width formed by the belt assembly is less than or equal to the transmission width of the second transmission unit 210. In this embodiment, this arrangement allows the hopper to rise and fall smoothly. At the lowest point, the material is poured out by the higher first transmission unit 410 and then transported to the second transmission unit, which is higher than the first transmission unit 410, for further transmission.

[0050] Furthermore, in this embodiment, the usage process, control process, and working process of the device of the present invention are described.

[0051] In this embodiment, to achieve control, a control component located inside the vehicle head is also included. This control component is connected to the power mechanisms of the first transmission unit, the second transmission unit, and the third transmission unit, as well as the control terminals of the first and second push units and the lifting component. In this embodiment, the control component controls various transmission processes. The second transmission unit and the lifting component of the hopper have a certain correlation; for example, when the hopper rises, the transfer unit 230 moves away from the mold assembly 220 and closer to the hopper. When the hopper descends, the transfer unit moves closer to the mold assembly, pouring the mixed material into the mold assembly. In this embodiment, time relays and other mechanisms, along with the design of corresponding operating parameters, can automate the entire control process. In this embodiment, multiple cylinders are used for lifting and horizontal movement, resulting in a compact structure, numerous motion-functioning components, low cost, and convenient control of the entire device.

[0052] The working process in this embodiment is as follows:

[0053] In this embodiment, the treatment of contaminated soil is taken as an example. The contaminated soil includes chemical reagent contaminated soil, toxic substance contaminated soil, and radiation contaminated soil. In the whole process, granite, cement and water are used to mix with the contaminated soil and then form a block structure. This block structure is then piled up in a pre-dug cave or other cave. In the prior art, the soil is directly buried. However, in this process, the contaminated soil will inevitably leak, causing secondary pollution. The device of the present invention reduces this problem.

[0054] The working process of the device of the present invention is as follows:

[0055] In this embodiment, contaminated soil, including chemical materials, is conveyed to the mixing unit 400 through a material leakage component and a feed inlet. The mixture is then mixed according to the specified proportions. The mixing speed can be set at a normal mixing speed. After mixing, the material from the mixing unit is transferred to the hopper via an inclined transition track below the mixing unit 400 and a first transmission unit 410. In this embodiment, the first transmission unit 410 is mounted on a rotating shaft 23, which rotates under the action of the shaft. It can be parallel to or perpendicular to the transition track. When idle, it is parallel to the transition track, separating the two vehicle bodies. When in use, it is perpendicular to the transition track, connecting the two vehicle bodies, so that the components on the two vehicle bodies form a complete integrated structure.

[0056] During use, the hopper 300 is raised and lowered along the inclined lifting component 310 on the inclined track 320 formed by the belt. When it descends to the lowest point, the material on the first transmission unit 410 falls directly into the hopper 300 under the action of gravity. When it rises to the highest point, the baffle or material outlet below the hopper 300 is opened, and the material enters the transfer unit 230 below the hopper by gravity. Then the transfer unit 230 moves along the second transmission unit 210, moving closer to or away from the mold component 220 to perform corresponding feeding.

[0057] For mold assembly 220, since the transfer unit 230 moves at a certain frequency, its material feeding to the mold is intermittent rather than one-time. This characteristic can be utilized to repeatedly compact the corresponding material, ensuring that the resulting clay embryo has good compactness, high strength, and is not easily loosened. Compared with other mold forming methods, the overall effect is better. At this time, the relevant parameters can be selected using principles such as brick making machines. In this embodiment, the mold forming process utilizes a vibration component to apply a certain pressure to the upper mold, so that the entire clay embryo can be clamped and has a certain resistance to pressure.

[0058] After the clay blank is formed using the mold assembly, it is clamped to the front by the clamping mechanism on the cutting mechanism, and then the corresponding cutting operation is performed on the worktable to finally form the designed clay blank size.

[0059] For the final step, to avoid secondary pollution caused by the crushing of the soil bales due to natural disasters, a PE film heat shrink oven is selected. This involves first wrapping the soil bales with PE film, followed by heat shrinking. This process repeatedly compresses and compacts the soil bales, while the PE film prevents contact with the outside environment. Even in the event of sudden external changes or minor vibrations caused by natural disasters, the resulting soil clumps are less likely to crumble, ensuring high safety and minimizing the impact and damage to the environment. This makes it safer to use, especially for handling difficult-to-treat particulate matter or other harmful particulate materials. The entire device is simple, low-cost, easy to assemble and disassemble, and convenient to transport, improving processing efficiency. In this embodiment, a commercially available PE film heat shrink oven, such as the PE film heat shrink machine from Guangzhou Fuhe Packaging Machinery Equipment Co., Ltd., can be used directly.
