Description

Technical Field

[0001] This invention relates to the field of powder transport tank technology, specifically a multi-curvature gradient irregular-shaped tank and a powder transport vehicle. Background Technology

[0002] As the core component for powder storage and unloading, the structural design of the tank directly determines transportation efficiency, material residue rate, energy consumption, and structural stability.

[0003] Traditional tanks typically employ a single circular cross-section design for the upper cylinder. While this design meets foundation pressure requirements, the fixed cross-sectional shape results in low space utilization, necessitating more transport trips to achieve the desired throughput and reducing transport efficiency. Furthermore, the supporting structure of the circular cross-section cylinder often consists of a single reinforcing rib, which is prone to localized stress concentration under long-term pressure from powder weight or transport bumps, leading to cylinder deformation and affecting service life. Additionally, the connection between the lower cone and upper cylinder of traditional tanks is often a right angle or a single curvature transition. This structure easily creates dead zones for material accumulation, making it difficult for powder to completely slide off during unloading, resulting in material waste and requiring regular manual cleaning, increasing maintenance costs. Moreover, traditional tanks rely solely on pneumatic arch breaking for unloading. The force of pneumatic arch breaking is relatively gentle and ineffective at breaking the solid "bridges" or "rat holes" formed by internal friction, compaction, or deliquescence in high-density, high-humidity, and highly viscous powders, still leading to unloading blockages and high material residue rates. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-curvature gradient irregular-shaped tank and a powder transport vehicle to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions: A multi-curvature gradient irregular-shaped tank includes: Multiple upper cylindrical bodies are connected in sequence. A lower cone is installed at the bottom of each upper cylindrical body. The upper cylindrical body is a curved shell structure formed by tangent multi-curvature circular arcs.

[0007] Furthermore, the internal support assembly includes multiple internal reinforcing rings and multiple triangular brackets; Multiple internal reinforcing rings are spaced apart inside the upper cylinder and located between two adjacent lower cones, which are connected by the internal reinforcing rings.

[0008] Furthermore, an outer reinforcing ring is provided at the outer side of the junction between the lower cone and the inner reinforcing ring, and the outer reinforcing ring, together with the lower cone and the inner reinforcing ring, forms a cavity.

[0009] Furthermore, the arch-breaking fluidization assembly includes an arch breaker, a first air inlet, and a first air pressure sensor.

[0010] Furthermore, the mechanical arch-breaking system includes a servo motor and reducer, a drive shaft, a spiral bevel gear steering box, and rotating wings; The servo motor and reducer are fixed inside the tank, and their output ends are connected to the drive shaft. The drive shaft is connected to the input end of the spiral bevel gear steering box, and the output end of the spiral bevel gear steering box is connected to the rotating fin, which is used to convert the horizontal rotational power into the vertical rotational power and drive the rotating fin to rotate. The servo motor and reducer are electrically connected to the control system.

[0011] Another object of the present invention is to provide a powder transport vehicle including a multi-curvature gradient irregular-shaped tank, the powder transport vehicle further comprising: The chassis assembly is used to support and mount the multi-curvature gradient irregular-shaped tank. The gas supply pipeline assembly is located on the side of the multi-curvature gradually changing irregular-shaped tank and is connected to the arch-breaking fluidizing component and the fluidizing component respectively; And the unloading pipe assembly, which is installed at the bottom of the lower cone and communicates with the interior of the lower cone.

[0012] Furthermore, the frame assembly includes an annular frame, which is fixedly connected to a multi-curvature gradient irregular-shaped tank, and a traveling mechanism is provided at the lower part of the annular frame.

[0013] Furthermore, the gas supply pipeline assembly includes a chamber air inlet pipe, an auxiliary blowing pipe, and a centralized control system; The air inlet pipe of the compartment is connected to the first air inlet and the second air inlet; The blowing aid pipe works in conjunction with the air inlet pipe of the chamber to supply air; The centralized control system is electrically connected to the first air pressure sensor, the second air pressure sensor, and the servo motor and reducer of the mechanical arch-breaking system, respectively.

[0015] The beneficial effects of this invention are: 1. In this invention, the upper cylinder adopts a curved shell structure with tangent multi-curvature circular arcs, which breaks the spatial limitation of traditional circular cross-section. Under the same overall vehicle size, the tank volume ratio is improved, which can reduce the number of transportation trips and improve the efficiency of powder transportation.

[0016] 2. In this invention, the lower cone and the upper cylinder are connected by a tangential arc transition.

The spiral bevel gear steering box, combined with seals, possesses dustproof, explosion-proof, and pressure-resistant characteristics, making it suitable for complex working conditions such as high temperature, high dust, and explosion-proof environments, further enhancing the adaptability of the tank and powder transport vehicle.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please see Figure 1 and Figure 2 In this embodiment of the invention, a multi-curvature gradient irregular-shaped tank includes: Multiple upper cylinders 13 are connected in sequence. A lower cone 14 is installed at the bottom of the upper cylinder 13. The upper cylinder 13 is a curved shell structure formed by tangent multi-curvature circular arcs. It is equipped with internal support components to enhance the structural strength. The lower cone 14 and the upper cylinder 13 are connected by a tangential arc surface, and the lower cone 14 and the internal support components form a cavity. An arch-breaking fluidization component is provided in the cavity, and a fluidization component for material fluidization discharge is provided at the bottom of the lower cone 14. The front end of the integral structure formed by multiple upper cylinders 13 and lower cones 14 is provided with a front end structure, and the rear end is provided with a tail end structure.

[0023] The tank is equipped with a mechanical arch-breaking system 5, which is electrically connected to the centralized control system 33. It is used to break the bridging and arching structure of the material in the upper part of the tank and forms a dual arch-breaking effect with the arch-breaking fluidization component. The front end structure includes a front end cap 11 and a front cone 12, with the front end cap 11 connected to the front cone 12; the end of the front cone 12 away from the front end cap 11 is connected to the upper cylinder 13 and the lower cone 14 at the corresponding positions. The tail structure is a rear end cap 15, which is connected to the upper cylinder 13 and the lower cone 14 at the corresponding positions.

[0024] When storing powder, the upper cylinder 13 with multiple curvature tangent arcs can make full use of the space, significantly improving the volume ratio compared with traditional circular cross-section cylinders, which can improve transportation efficiency and solve the problem of low space utilization of traditional tanks.

[0025] When unloading is required, the mechanical arch-breaking system 5 first starts operating to break the bridging and arching of the material in the upper part of the tank, allowing the material to slide down to the lower cone 14 area by gravity. Subsequently, the arch-breaking fluidization component in the cavity formed by the lower cone 14 and the internal support components starts working, first breaking the arches of the powder accumulated at the lower cone 14 to prevent powder blockage. The tangential arc-shaped connection structure eliminates the dead angles of traditional right angles or single curvature transitions, reducing the amount of powder accumulation and minimizing material waste. After the arch is broken, the powder slides to the bottom of the lower cone 14, and the fluidization component is activated to convert the powder into a fluidized state for easy and rapid discharge.

[0026] Example 2: Please see Figures 1-5 Based on Embodiment 1, the internal support assembly includes multiple internal reinforcing rings 18 and multiple triangular brackets 19; Multiple internal reinforcing rings 18 are spaced apart inside the upper cylinder 13 and located between two adjacent lower cones 14, which are connected by the internal reinforcing rings 18. The triangular bracket 19 is arranged at intervals with the internal reinforcing ring 18 and is fixedly connected to the inner wall of the upper cylinder 13.

[0027] In this embodiment, when the tank stores powder, the internal reinforcing ring 18 can disperse the radial pressure of the powder on the upper cylinder 13, while the triangular bracket 19 enhances the axial deformation resistance of the upper cylinder 13. The combination of the two improves the pressure resistance of the upper cylinder 13, avoids cylinder deformation caused by long-term use, and extends the service life of the tank.

[0028] During unloading, as the powder decreases, the internal pressure of the tank changes. The internal reinforcing ring 18 and the triangular support 19 can balance the pressure fluctuations in real time to prevent the upper cylinder 13 from being locally dented due to sudden pressure changes.

[0029] Compared to traditional single-reinforcing rib structures, this composite support system improves the tank's resistance to bumps and reduces the risk of structural damage during transportation.

[0030] Example 3: Please see Figures 1-5 Based on Example 1, an outer reinforcing ring 20 is provided at the outer side of the junction of the lower cone 14 and the inner reinforcing ring 18. The outer reinforcing ring 20, the lower cone 14 and the inner reinforcing ring 18 cooperate to form a cavity.

[0031] In this embodiment, the cavity provides a stable installation and working space for the arch-breaking fluidization component, avoids gas leakage during the arch-breaking process, ensures that the gas can accurately act on the accumulated material during the arch-breaking stage, and reduces energy waste.

[0032] The outer reinforcing ring 20 and the inner reinforcing ring 18 form a support structure that complements each other, enhancing the strength of the connection between the lower cone 14 and the upper cylinder 13 and solving the problem of easy cracking of the weld at the connection.

[0033] Example 4: Please see Figure 1 and Figure 6 Based on Embodiment 1, the arch-breaking fluidization assembly includes an arch-breaking device 161, a first air inlet 162, and a first air pressure sensor 163. The arch-breaking device 161 and the first air pressure sensor 163 are disposed on the inner wall of the lower cone 14, and the first air inlet 162 is disposed on the outer side of the lower cone 14 and communicates with the cavity. The first pressure sensor 163 is used to detect the air pressure in the cavity.

[0034] When powder accumulates in the lower cone 14, the first air pressure sensor 163 monitors the air pressure inside the cavity in real time: if the air pressure increases, it indicates that the powder accumulation is thick and the air permeability resistance is high, and the centralized control system 33 controls the first air inlet 162 to increase the air supply, and the arch breaker 161 works with high-pressure gas to quickly break the arch; if the air pressure decreases, it indicates that the powder is decreasing, and the air supply is reduced. This precise control avoids the energy waste of traditional continuous air supply.

[0035] The fluidization assembly includes a fluidizer 171, a second air inlet 172, and a second air pressure sensor 173; Fluidizer 171 and second pressure sensor 173 are located on the inner side of the bottom of lower cone 14; The second air inlet 172 is located on the outer side of the bottom of the lower cone 14 and is connected to the interior of the lower cone 14; The second pressure sensor 173 is used to detect the air pressure at the bottom of the lower cone 14.

[0036] When the powder after the arch is broken slides to the bottom of the lower cone 14, the second air pressure sensor 173 detects the bottom air pressure: if the air pressure is high and there is more material, the second air inlet 172 increases the air supply, and the fluidizer 171 fully fluidizes the material, accelerating the unloading speed; if the air pressure is low and there is less material, the air supply is reduced. Compared with the traditional single-process structure, the unloading efficiency is improved, and the residual rate of material is further reduced.

[0037] Example 5: Please see Figure 1 , Figure 12 , Figure 13 Based on Example 1, the mechanical arch-breaking system 5 includes a servo motor and reducer 51, a drive shaft 52, a spiral bevel gear steering box 53, and a rotating wing 54. The servo motor and reducer 51 are electrically connected to the centralized control system 33, and are precisely controlled by it to start, stop and operate. The servo motor and reducer 51 output rotational power, which is transmitted to the spiral bevel gear steering box 53 via the transmission shaft 52. The spiral bevel gear set inside converts the horizontal input rotational power into the vertical output rotational power, thereby driving the rotating wing 54 to rotate slowly and powerfully in the arching area at the top of the tank. When the powder inside the tank forms an arched structure or rat hole due to internal friction, compaction, or deliquescence, the rotating blade 54 cuts into the stress point of the material arch from the bottom or side, and disrupts the mechanical balance of the material through shearing force and pushing force, causing the material arch to collapse. The material then resumes flow under gravity and slides down to the area of ​​the lower cone 14, forming a double arch breaking with the arch breaking fluidization component, ensuring that there is no blockage or residue during the unloading process. The spiral bevel gear steering box 53 of the mechanical arch-breaking system 5, with its sealing design, has the characteristics of dustproof, explosion-proof, and pressure-resistant. It can operate stably under complex working conditions such as high temperature, high dust, and explosion-proof conditions. Moreover, the overall structure is compact, and the standardized flange connection makes it convenient to inspect and replace the rotating blades 54.

And the unloading pipe assembly 4, which is installed at the bottom of the lower cone 14 and communicates with the interior of the lower cone 14.

[0039] The frame assembly 2 includes an annular frame 21, which is fixedly connected to the multi-curvature gradient irregular tank 1. A walking mechanism 22 is provided at the lower part of the annular frame 21.

[0040] Among them, the gas supply pipeline assembly 3 includes a chamber air inlet pipe 31, an auxiliary blowing pipe 32, and a centralized control system 33; The air inlet pipe 31 of the compartment is connected to the first air inlet 162 and the second air inlet 172; The blow-off pipe 32 works in conjunction with the air inlet pipe 31 of the compartment to supply air; The centralized control system 33 is electrically connected to the first air pressure sensor 163, the second air pressure sensor 173, and the servo motor and reducer 51 of the mechanical arch-breaking system 5, respectively, and is used to adjust the air supply according to the detected air pressure value, and at the same time control the start-up, shutdown and operation status of the mechanical arch-breaking system 5.

[0041] The centralized control system 33 is electrically connected to the first pressure sensor 163 and the second pressure sensor 173 respectively, and is used to adjust the air supply according to the detected air pressure value.

[0042] The unloading pipeline assembly 4 includes an unloading valve connector 41, a pipeline 42, a butterfly valve 43, and a discharge port 44. One end of the discharge valve connector 41 is connected to the bottom of the lower cone 14, and the other end is connected to the pipe 42; Butterfly valve 43 is installed on pipe 42; The discharge port 44 is located at the end of the pipeline 42 away from the unloading valve connector 41.

[0043] In this embodiment, the multi-curvature gradient irregular-shaped tank 1 is installed on the annular frame 21 of the frame assembly 2, and the walking mechanism 22 at the bottom of the annular frame 21 realizes the movement of the whole vehicle; the compartment air inlet pipe 31 of the air supply pipeline assembly 3 is connected to the first air inlet 162 and the second air inlet 172, and the blowing pipe 32 assists in air supply. During the unloading operation, the centralized control system 33 first controls the mechanical arch-breaking system 5 to start, breaking the bridging and arching state of the material in the upper part of the tank, so that the material slides down to the lower cone 14; then, according to the air pressure value detected by the first air pressure sensor 163, it controls the arch-breaking fluidization component to perform pneumatic arch breaking, and the material slides further down to the bottom of the lower cone 14; finally, according to the bottom air pressure value, the second air pressure sensor 173 controls the fluidization component to fluidize the material, the butterfly valve 43 opens, and the material is discharged from the discharge port 44 through the pipeline 42; The discharge valve connector 41 of the discharge pipeline assembly 4 connects the bottom of the lower cone 14 to the pipeline 42.
