Description

Technical Field

[0001] This invention relates to the field of material transport equipment, and in particular to a feeding device and a powder and granular material transport vehicle. Background Technology

[0002] The powder and granular material transport vehicle is suitable for bulk transport of dry powder and granular materials with a particle diameter of no more than 0.1mm, such as fly ash, cement, lime powder, ore powder, and granular alkali. It is mainly used in cement plants, cement warehouses, and large construction sites, and can save a lot of packaging materials and loading and unloading labor.

[0003] In existing technologies, powder and granular material transport vehicles include a chassis and a tank. The angle of the side plates inside the tank affects the material flowability, discharge speed, and residual rate. Due to the physical properties of the materials themselves, all materials have a certain angle of repose. Therefore, the angle of the side plates inside the tank must be larger than the angle of repose of the loaded material to achieve rapid unloading and reduce residual rate. Due to this limitation, the tank interior needs to be divided into compartments, and for wider adaptability, the interior is designed in a funnel shape to facilitate the material flow along the side plates to the central fluidized bed. Driven by high-speed gas, the material forms a fluid-like state and is then transported to other storage spaces via the discharge pipe.

[0004] However, due to the limitations of the tank body, the angle of the side plates cannot be made infinitely large. Therefore, the finished tank body cannot load materials with an angle of repose greater than the design angle, which limits the types of materials the vehicle can transport. Furthermore, the existence of the design angle increases the difficulty of manufacturing, increases the weight of the side plates, and reduces the effective volume of the cylinder. In addition, existing powder material transport vehicles are divided into different spaces, and each space needs to be equipped with a discharge pipe, which further increases the weight of the entire powder material transport vehicle and is also not conducive to maintenance.

[0005] Therefore, how to improve the applicability and efficiency of the feeding device is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding device and a powder material transport vehicle that has a wider range of applications, higher space utilization, and higher feeding efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A feeding device, comprising:

[0009] The cylinder is used to hold materials;

[0010] A vaporization bed is installed at the bottom inner side of the cylinder.

[0011] A side plate is installed inside the cylinder and located on at least one side of the vaporization bed. Material inside the cylinder can slide down the side plate onto the vaporization bed, and the side plate, the vaporization bed, and the cylinder extend in the same direction.

[0012] Guide rails are installed inside the cylinder;

[0013] A suction pipe assembly is used to transport the material in the vaporization bed to the outside of the cylinder, and the suction pipe assembly is retractable;

[0014] A driving component is mounted on the guide rail and connected to the suction pipe assembly to drive the suction pipe assembly to extend and retract along the extension direction of the vaporization bed.

[0015] Preferably, the suction pipe assembly includes a discharge pipe, a sleeve assembly, and a suction port component connected in sequence, the suction port component being located above the vaporization bed, and the discharge port of the discharge pipe extending to the outside of the cylinder.

[0016] Preferably, the sleeve assembly includes a plurality of sleeve units that are sequentially sleeved together, and a limiting portion is provided between adjacent sleeve units to prevent adjacent sleeve units from separating.

[0017] Preferably, the vaporization bed is provided with side plates on both sides, and the side plates are inclined from top to bottom toward the direction close to the vaporization bed.

[0018] Preferably, it further includes a support plate for supporting the side plate, the side of the support plate opposite to the side plate being fixed to the inner wall of the cylinder.

[0019] Preferably, there are multiple support plates arranged at intervals along the axial direction of the cylinder.

[0020] Preferably, the support plate is provided with a plurality of weight-reducing holes.

[0021] Preferably, the driving component includes a power component and a gear, the gear is mounted on at least one side of the power component, and the guide rail has a plurality of toothed holes that can mesh with the gear in the extending direction.

[0022] Preferably, the system further includes a connector and a support shaft. The connector is installed between the drive component and the suction tube assembly, and the support shaft is installed on the connector. The side of the guide rail is provided with a groove for the support shaft to be inserted.

[0023] The present invention also provides a powder material transport vehicle, including the feeding device described in any one of the above.

[0024] The feeding device provided by the present invention includes: a cylinder for carrying materials; a vaporization bed installed at the bottom inner side of the cylinder; a side plate installed inside the cylinder and located on at least one side of the vaporization bed, wherein materials inside the cylinder can slide down along the side plate onto the vaporization bed, and the side plate, the vaporization bed, and the cylinder extend in the same direction; a guide rail installed inside the cylinder; a suction pipe assembly for conveying materials in the vaporization bed to the outside of the cylinder, the suction pipe assembly being retractable; and a driving component installed on the guide rail, the driving component being connected to the suction pipe assembly to drive the suction pipe assembly to extend and retract along the extension direction of the vaporization bed. The feeding device provided by this invention, by having the side plates, the vaporization bed, and the cylinder extend in the same direction, makes the vaporization bed straight and easier to install and arrange. The side plates allow the material in the cylinder to fall onto the vaporization bed, and then the material transportation work on the entire vaporization bed is completed by extending and retracting the suction pipe assembly.

Alternatively, the support shaft can also slide within the groove without rolling.

[0026] The powder material transport vehicle provided by the present invention is equipped with the above-mentioned feeding device. Since the feeding device has the above-mentioned technical effects, the powder material transport vehicle equipped with the feeding device should also have the corresponding technical effects.

[0039] In this embodiment, the feeding device includes:

[0040] Cylinder 1, used to carry materials;

[0041] The vaporization bed 2 is installed at the bottom inner side of the cylinder 1;

[0042] Side plate 3 is installed inside cylinder 1 and located on at least one side of vaporization bed 2. Material inside cylinder 1 can slide down along side plate 3 onto vaporization bed 2, and the side plate 3, vaporization bed 2 and cylinder 1 extend in the same direction.

[0043] Guide rail 4 is installed inside cylinder 1;

[0044] The suction pipe assembly 5 is used to transport the material inside the vaporization bed 2 to the outside of the cylinder 1. The suction pipe assembly 5 is retractable.

[0045] The drive component 6 is mounted on the guide rail 4 and is connected to the suction pipe assembly 5 to drive the suction pipe assembly 5 to extend and retract along the extension direction of the vaporization bed 2.

[0046] Specifically, the cylinder 1 is preferably a cylindrical cylinder 1, with both ends of the cylinder 1 being arc surfaces to improve the space utilization rate inside the cylinder 1; the guide rail 4 should be suspended above the vaporization bed 2, with both ends of the guide rail 4 installed at both ends of the cylinder 1 to achieve the function of fixing and supporting the suction pipe assembly 5; the drive component 6 is installed on the upper part of the guide rail 4, and the suction pipe assembly 5 is connected to the lower part of the drive component 6. The drive component 6 moves on the guide rail 4, driving the suction pipe assembly 5 to extend and retract along the extension direction of the vaporization bed 2; the vaporization bed 2 includes a permeable layer, a permeable layer support, and a permeable layer perimeter pressure strip, the purpose of which is to use gas to pass through the permeable layer, and use the gas flow rate to drive the particles to suspend, forming a vaporization phenomenon; the suspended particles have fluid characteristics and can move along the airflow direction to achieve the purpose of conveying along the suction pipe assembly 5.

[0047] In this feeding device, the space between the side plate 3 inside the cylinder 1 and the vaporized bed 2 serves as a material storage space. This eliminates the lateral angled material slide plate found in existing vehicles, replacing it with a straight channel and an additional retractable suction pipe assembly 5. The material is unloaded by moving along the vaporized bed 2 located in the middle through the suction port of the suction pipe assembly 5. Because the suction pipe assembly 5 is retractable, the position of the suction port can be moved. The angle of repose of the material is in the longitudinal dimension of the cylinder 1, having no impact on the material conveying within the cylinder 1. Therefore, the vaporized bed 2 located inside the cylinder 1... At least one side plate 3 can have its angle increased as much as possible, that is, it can extend as vertically as possible to be able to load any powder particles and achieve a multi-functional purpose. Since the plates arranged in the axial direction of the cylinder 1 are eliminated, the space utilization range inside the cylinder 1 is significantly improved. Therefore, the increase in the angle of the side plate 3 will not have much impact on the utilization rate of the internal space of the cylinder 1. Of course, the main purpose of the side plate 3 is to guide the material onto the vaporization bed 2. Therefore, the inclination of the side plate 3 should not be too large, so as not to prevent the material from falling onto the vaporization bed 2.

[0048] The feeding device provided by the present invention makes the vaporization bed 2 more convenient to install and arrange by making the side plate 3, the vaporization bed 2 and the cylinder 1 extend in the same direction. The side plate 3 is used to drop the material from the cylinder 1 onto the vaporization bed 2, and then the telescopic suction pipe assembly 5 is used to complete the transportation of the material on the entire vaporization bed 2. Only one set of suction pipe assembly 5 is required, and there is no need for partitions inside the cylinder 1 to transport all the material. This solves the problem of complex and difficult manufacturing, and the space utilization rate of the cylinder 1 is greatly improved, the weight is reduced, and the load capacity utilization coefficient of the whole vehicle is improved.

[0049] In some embodiments, the suction pipe assembly 5 includes a discharge pipe 51, a sleeve assembly 52, and a suction port component 53 connected in sequence. The suction port component 53 is located above the vaporization bed 2, and the discharge port of the discharge pipe 51 extends to the outside of the cylinder 1. Specifically, the first end of the sleeve assembly 52 is connected to the suction port component 53, and the second end of the sleeve assembly 52 is connected to the discharge pipe 51. Further, the suction pipe assembly 5 is preferably a steel pipe, which has high strength and a long service life.

[0050] In some embodiments, the sleeve assembly 52 includes a plurality of sleeve units that are sequentially nested together, and a limiting part is provided between adjacent sleeve units to prevent them from separating. For example, the sleeve assembly 52 includes a first sleeve unit, a second sleeve unit, and a third sleeve unit. The first, second, and third sleeve units are nested together to achieve a telescopic function. Of course, the sleeve assembly 52 also includes a fourth and a fifth sleeve unit. The number of sleeve units can be set according to the size of the cylinder 1 and is not limited to the method given in this embodiment. Through the nesting of the plurality of sleeve units, when the suction port component 53 needs to move, the sleeve units move away from or closer to each other, thereby realizing the translation of the suction port component 53 and conveying the material on the entire strip-shaped vaporization bed 2. Furthermore, an annular limiting step can be provided between adjacent sleeve units. The annular limiting step constitutes a limiting part, which not only plays a sealing role but also prevents adjacent sleeve units from separating and affecting the feeding. Of course, if space permits, the sleeve assembly 52 can also be a coiled hose.

[0051] In some embodiments, side plates 3 are provided on both sides of the vaporization bed 2, and the side plates 3 are inclined from top to bottom toward the direction close to the vaporization bed 2. Specifically, by providing side plates 3 on both sides of the vaporization bed 2, the material storage space inside the cylinder 1 is symmetrically arranged, which can ensure the uniformity of material falling and facilitate the arrangement of the track. The extension and retraction movement of the suction pipe assembly 5 driven by the drive component 6 effectively solves the problem of material flowability inside the cylinder 1.

[0052] In some embodiments, a support plate 7 for supporting the side plate 3 is also included, with the side of the support plate 7 facing away from the side plate 3 fixed to the inner wall of the cylinder 1. Specifically, the side of the support plate 7 that connects to the inner wall of the cylinder 1 has the same curvature as the inner wall of the cylinder 1 to improve connection stability. Specifically, the support plate 7 is preferably welded to the inner wall of the cylinder 1.

[0053] In some embodiments, there are multiple support plates 7, which are arranged at intervals along the axial direction of the cylinder 1. By providing multiple support plates 7, the installation of the side plate 3 can be made more secure. Furthermore, the support plates 7 are provided with a number of weight-reducing holes 71, which effectively reduces the weight of the support plates 7, thereby reducing the weight of the entire feeding device; of course, the support plates 7 can also be other structures, such as brackets.

[0054] In some embodiments, an air inlet pipe 9 is also included. The air inlet pipe 9 is connected to the cylinder 1. Gas enters the vaporization bed 2 through the air inlet pipe 9. The vaporization bed 2 plays the role of suspending and vaporizing the material. The material enters the sleeve unit through the movable suction port component 53. The material is transported to the external storage through the discharge pipe 51 along each sleeve unit.

[0055] In some embodiments, the driving component 6 includes a power component 61 and a gear 62. The gear 62 is mounted on at least one side of the power component 61, and the guide rail 4 has a plurality of toothed holes 41 that can mesh with the gear 62 in its extending direction. Specifically, the power component 61 is preferably a motor, which is fixedly connected to the suction port component 53. The gear 62 is connected to the drive shaft of the motor, and the gear 62 meshes with the toothed holes 41 on the surface of the guide rail 4. The rotation of the gear 62 drives the movement of the suction port component 53, which moves along the extending direction of the vaporization bed 2, so that the suction port can always be in contact with the material to achieve the purpose of unloading. Of course, the toothed holes 41 on the guide rail 4 can also be replaced with toothed grooves or racks, etc., as long as they can mesh with the gear 62. In one specific embodiment, there are at least two guide rails 4, and at least one guide rail 4 is provided on both sides of the power component 61. The number of gears 62 is the same as the number of guide rails 4. By connecting the power component 61 with the guide rails 4 on both sides, the stability of the power component 61 can be improved, thereby improving the movement stability of the suction port component 53.

[0056] In some embodiments, a connector 8 and a support shaft 81 are also included. The connector 8 is installed between the drive component 6 and the suction tube assembly 5, and the support shaft 81 is installed on the connector 8. The side of the guide rail 4 is provided with a groove 42 for the support shaft 81 to be inserted. Preferably, the support shaft 81 is a roller that can roll within the groove 42 to reduce resistance and ensure smooth movement and extension of the suction tube assembly 5. The above arrangement uses the connector 8 to fix the drive component 6 and the suction tube assembly 5, and then uses the support shaft 81 to limit the position of the connector 8, thereby ensuring the stability of the suction tube assembly 5 during movement and preventing shaking. Of course, the support shaft 81 can also be non-rolling and only slide within the groove 42. Furthermore, in order to improve the stability of the connector 8, at least one support shaft 81 is provided on both sides of the connector 8, and guide rails 4 are provided on both sides of the power component 61. The sides of the two guide rails 4 that are close to each other are provided with grooves 42, and the two support shafts 81 are respectively located in the two grooves 42 to limit the lateral position of the connector 8. During installation, simply slide the two support shafts 81 into the grooves 42 from the ends of the two guide rails 4.

[0057] This feeding device has the following advantages:

[0058] 1. Simple structure: The axial direction of cylinder 1 does not require compartmentation, the structure is simple, there are few parts, and it is easy and convenient to manufacture;

[0059] 2. Lightweight: The transverse side plate 3 and its associated support plate 7 and partition plate are eliminated from the existing technology. The multiple discharge pipes 51 are reduced to one discharge pipe 51. A movable suction port component 53 is adopted. Through structural optimization, the weight of the feeding device is reduced, which is conducive to improving the load capacity utilization coefficient.

[0060] 3. Improved space utilization of cylinder 1: After the horizontal side plate 3 is removed from the inside of cylinder 1, the bottom is flat and can be used to load materials, thus improving the space utilization of cylinder 1.

[0061] 4. Low residual rate: Due to the forced movement of the suction port, the material residual rate is extremely low;

[0062] 5. Wide adaptability, enabling multi-functional vehicle transportation: Due to the presence of the movable suction port component 53, the flowability of materials is no longer limited by the angle of repose. Any powder or granular material can be moved along the vaporization bed 2 above it and then transported out through the sleeve assembly 52 and the discharge port. This provides better adaptability to materials, and the vehicle can be loaded with various materials, enabling multi-functional vehicle transportation.
