Technical Field

[0001] This utility model relates to the field of tank truck technology, and in particular to a tank truck and its tank body. Background Technology

[0002] With the development of the road transport industry, the demand for single-trip transport volume is also increasing. However, due to standard restrictions on the overall length, width, and height of tank trucks, it is difficult to further increase the volume of existing tank trucks while still meeting these restrictions.

[0003] Therefore, how to increase the tank volume of tank trucks while meeting existing standard limitations has become an urgent issue. Utility Model Content

[0004] The purpose of this utility model is to provide a tanker truck and its tank body, which has a large volume.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of this application, this application provides a tank body for holding materials. The tank body includes an upper cylinder body and a plurality of lower cones arranged sequentially along the axial direction of the upper cylinder body and disposed below the upper cylinder body. The peripheral walls of each lower cone body are inclined inward from top to bottom. Among all the lower cone bodies, the one located at the front is the front cone body. The tank body also includes a front end cap, which is fixed between the front end of the upper cylinder along the axial direction and the front end of the front cone; the front end cap is arranged inclined from top to bottom and backward, and the inclination angle of the front end cap is the same as the inclination angle of the front end face of the peripheral wall of the front cone.

[0006] In some embodiments, the tilt angle of the front end cap is greater than 40°.

[0007] In some embodiments, the maximum dimension of the front end cap in the left-right direction is the maximum dimension of the tank body in the left-right direction; The maximum dimension of the front end cap in the left-right direction is greater than 2m.

[0008] In some embodiments, the top of the front end cap is lower than the top of the upper cylinder; The tank also includes a transition plate, which is connected between the front end face of the upper cylinder and the rear side face of the front end cap; the transition plate is arranged inclined downwards from back to front.

[0009] In some embodiments, the rear side of the front end cap slopes forward from bottom to top and gradually moves away from the front side of the upper cylinder. The rear side of the front end cap is connected to the upper cylinder and the transition plate. The axial dimension of the portion of the front end cap connected to the upper cylinder is smaller than the axial dimension of the portion of the front end cap connected to the transition plate in the upper cylinder.

[0010] In some embodiments, the outer contour of the front end cap includes a first arc-shaped edge and a second arc-shaped edge, both of which are arc-shaped; The first arc-shaped edge is connected between the two opposite ends of the second arc-shaped edge. The first arc-shaped edge is located above the rear side of the second arc-shaped edge. The concave surface of the first arc-shaped edge faces downward. The first arc-shaped edge is connected to the front end of the upper cylinder and the transition plate. The concave surface of the second arc-shaped edge faces the first arc-shaped edge along the axial direction of the upper cylinder. The second arc-shaped edge is connected to the front end of the front cone.

[0011] In some embodiments, the front end cap has a rearwardly opening concave surface; The front end cap has a semi-elliptical cross-section, and the diameter of the front end cap in the left-right direction is larger than its diameter in the up-down direction.

[0012] In some embodiments, the rearmost of all the lower cones is the rear cone; The tank body also includes a rear end cap, which is connected to the rear end of the upper cylinder and the rear end of the rear cone; the cross-section of the rear end cap is elliptical, and the diameter of the rear end cap in the left-right direction is larger than its diameter in the up-down direction; the rear end cap has a concave surface with an opening facing forward.

[0013] In some embodiments, each of the lower cones is inverted cone-shaped, and all of the lower cones have the same cone angle; Each of the lower cones has a discharge port at its bottom; the discharge port is equipped with a discharge valve for controlling the opening and closing of the discharge port.

[0014] According to another aspect of this application, this application provides a tanker truck, including a vehicle body and a tank disposed on the vehicle body, wherein the tank adopts any of the tanks described above.

[0015] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the front end cap is directly fixed between the front end of the upper cylinder and the front end of the front cone along the axial direction. Compared with the prior art, where the front end cap needs to be connected to the upper cylinder and the front cone through a transition conical section, the above design eliminates the setting of the transition conical section that narrows from back to front. Instead, the front end cap is directly set at the opening formed by the front ends of the upper cylinder and the front cone after the transition conical section has not narrowed. This is beneficial to increase the size of the front end cap in the left and right directions. Thus, while ensuring that the overall height of the tank remains unchanged, the space in the left and right directions of the upper cylinder and the front side of the front cone can be reasonably utilized to increase the volume of the front end cap, thereby increasing the volume of the tank. This allows the tank to hold more material at a time, increasing the material transport capacity and improving the efficiency of a single transport. Furthermore, compared to existing technologies, the above design can reduce the axial dimensions of the tank while keeping the total tank volume unchanged. In addition, the above design can reduce the number of annular welds at the front of the tank, which can reduce the resistance to material sliding, shorten the unloading time, and also improve the production efficiency of the tank.

[0016] Furthermore, the front end cap is arranged at an angle, and the angle of inclination is consistent with the angle of inclination of the front end face of the peripheral wall of the front cone. This facilitates a smooth transition between the front end cap and the front cone, and allows the material to slide down the inner surface of the peripheral wall of the front end cap to the front cone, thereby improving the smoothness of material flow during unloading and increasing the unloading speed.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] This application provides a tank for holding materials to facilitate the storage and transportation of materials.

[0025] The material can be in the form of spherical or cylindrical particles.

[0026] The following detailed description of specific embodiments of the tank body of this application is provided in conjunction with the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of the tank structure in this embodiment. Figure 2 for Figure 1 A schematic diagram of the middle tank along the AA direction.

[0028] refer to Figure 1 and Figure 2 The tank body includes an upper cylindrical body 1 and multiple lower cones 2 arranged sequentially along the axial direction of the upper cylindrical body 1 and positioned below the upper cylindrical body 1. The peripheral walls of each lower cone 2 are inclined inward from top to bottom. Among all the lower cones 2, the one located at the front is the front cone 2a. The tank body also includes a front end cap 3, which is fixed between the front end of the upper cylindrical body 1 along the axial direction and the front end of the front cone 2a. The front end cap 3 is arranged inclined backward from top to bottom, and the inclination angle of the front end cap 3 is the same as the inclination angle of the front end face of the peripheral wall of the front cone 2a.

[0029] In this application, the front end cap 3 is directly fixed between the front end of the upper cylinder 1 along the axial direction and the front end of the front cone 2a. Compared with the prior art, where the front end cap 3 needs to be connected to the upper cylinder 1 and the front cone 2a through a transition conical section, the above design eliminates the setting of the transition conical section that narrows from back to front. Instead, the front end cap 3 is directly set at the opening formed by the front end of the upper cylinder 1 and the front cone 2a after the transition conical section has narrowed. This is beneficial to increase the size of the front end cap 3 in the left and right directions and make reasonable use of the space in the left and right directions of the upper cylinder 1 and the front side of the front cone 2a. Thus, while keeping the overall height of the tank unchanged, the volume of the front end cap 3 can be increased, thereby increasing the volume of the tank. This allows the tank to hold more material at a time, increasing the material transport capacity and improving the efficiency of a single transport. Furthermore, compared to existing technologies, the above design can reduce the axial dimensions of the tank while keeping the total tank volume unchanged. In addition, the above design can reduce the number of annular welds at the front of the tank, which can reduce the resistance to material sliding, shorten the unloading time, and also improve the production efficiency of the tank.

[0030] Furthermore, the front end cap 3 is arranged at an angle, and the angle of inclination is consistent with the angle of inclination of the front end face of the peripheral wall of the front cone 2a. This facilitates a smooth transition between the front end cap 3 and the front cone 2a, and allows the material to slide down the inner surface of the peripheral wall of the front end cap 3 to the front cone 2a, thereby improving the smoothness of material flow during unloading and increasing the unloading speed.

[0031] In this article, the axial direction of the tank is the front-to-back direction, and the direction perpendicular to the axial direction of the tank within the same horizontal plane is the left-to-right direction.

[0032] It should be noted that, taking the vertical plane containing the center line of the front cone 2a as a reference, this vertical plane extends to the left and right and intersects with the left and right sides of the front cone 2a. This vertical plane is the interface between the front end face and the rear end face of the peripheral wall of the front cone 2a.

[0033] The inclination angle of the perimeter wall of each lower cone 2 refers to the acute angle between the inner side of each lower cone 2 and the horizontal plane in any vertical section of each lower cone 2.

[0034] refer to Figure 1 and Figure 2 The tank body includes an upper cylinder 1, multiple lower cones 2, a front end cap 3, and a rear end cap 4.

[0035] The upper cylinder 1 has a semi-elliptical cross-section with an open bottom, and its diameter in the left-right direction is larger than its diameter in the top-bottom direction. Compared to a circular structure, the semi-elliptical shape has a wider width, increasing the overall width of the upper part of the tank. Specifically, the lower end face of the upper cylinder 1 has a larger cross-sectional area, and the area of ​​the upper end face of the matching lower cone 2 also increases accordingly, thereby increasing the overall volume of the tank and thus increasing the effective loading capacity of the tank, thereby improving the single-trip transport capacity of the tanker truck.

[0036] A manhole is provided at the top of the upper cylinder 1, through which materials can be loaded into the tank and workers can easily enter and exit the tank.

[0037] Optionally, a manhole cover 6 is provided at the manhole, which is used to open and close the manhole.

[0038] It should be noted that the upper cylinder 1 can be a single unit or it can consist of multiple upper cylinder sections arranged sequentially along the axial direction, depending on the actual needs.

[0039] Multiple lower cones 2 are arranged sequentially along the axial direction of the upper cylinder 1 and positioned below the upper cylinder 1. It should be noted that when the upper cylinder 1 is composed of multiple upper cylinder sections, each upper cylinder section can correspond one-to-one with a lower cone 2, or one upper cylinder section can correspond to multiple lower cones 2.

[0040] Each lower cone 2 has a discharge port at its bottom for unloading materials from the tank. Specifically, the lower cone 2 located at the front is the front cone 2a. The multiple lower cones 2 also include a rear cone 2b and at least two middle cones located between the front cone 2a and the rear cone 2b. The bottoms of the front cone 2a, each middle cone, and the rear cone 2b are respectively provided with discharge ports.

[0041] Optionally, each lower cone 2 is provided with a discharge valve 7 at its discharge port, which is used to control the opening and closing of the corresponding discharge port.

[0042] Optionally, the peripheral walls of each lower cone 2 are inclined inward from top to bottom, that is, the diameter of each lower cone 2 gradually decreases from top to bottom. This design allows the inner peripheral walls of the lower cone 2 to guide the sliding of the material, enabling the material to slide more smoothly from top to bottom to the bottom discharge port of the lower cone 2, which is more conducive to unloading. In addition, it can save material in manufacturing the lower cone 2, reduce the weight of the lower cone 2, and facilitate the lightweighting of the tank while improving the smoothness of material unloading.

[0043] Specifically, each lower cone 2 is cone-shaped, and all lower cones 2 have the same cone angle. Since the diameter of each lower cone 2 gradually decreases from top to bottom, each lower cone 2 is inverted with its apex facing down. Furthermore, the centerline of each lower cone 2 extends upwards from its bottom apex, i.e., it extends vertically.

[0044] In this design, the inclination angle of the peripheral wall of each lower cone 2 is greater than the angle of repose of the material. This design allows the inner surface of the peripheral wall of each lower cone 2 to have a large inclination angle, which can reduce the contact stress between the material and the inner surface of the peripheral wall of the lower cone 2, making it easier for the material to slide down along the inner surface of the peripheral wall of the lower cone 2. It also allows the material to overcome the friction and adhesion between material particles under its own gravity, avoiding the formation of a stable arched structure inside the lower cone 2, thereby ensuring the continuity and smoothness of material discharge during the unloading process and reducing residue.

[0045] It should be noted that the angle of repose of a material refers to the stable tilt angle formed between material particles due to friction and adhesion when the material naturally accumulates to form a stable cone. For example, the angle of repose of the material in this article is less than 30°.

[0046] For example, the inclination angle of the peripheral wall of each lower cone 2 is greater than 40°. This design ensures that the inclination angle of the peripheral wall of each lower cone 2 is greater than the material repose angle. By increasing the inclination angle, the cone angle of each lower cone 2 is enlarged, which is conducive to increasing the volume of the lower cone 2, so as to maximize the volume of the tank.

[0047] Specifically, each lower cone 2 includes a left cone portion 21 and a right cone portion 22 distributed along the left and right sides, and a front cone portion 23 and a rear cone portion 24 distributed along the front and back sides. Specifically, the bottoms of the left cone portion 21 and the right cone portion 22 are connected, and the left cone portion 21 and the right cone portion 22 gradually move away from each other from bottom to top. The front cone portion 23 is connected between the lower front parts of the left cone portion 21 and the right cone portion 22, and the rear cone portion 24 is connected between the lower rear parts of the left cone portion 21 and the right cone portion 22. The bottoms of the front cone portion 23 and the rear cone portion 24 are connected, and the front cone portion 23 and the rear cone portion 24 gradually move away from each other from bottom to top. Among them, the left cone portion 21, the right cone portion 22, the front cone portion 23, and the rear cone portion 24 together form an inverted cone-shaped structure that runs through the front and back, with an opening at the top and an opening at the bottom.

[0048] The left cone portion 21 and the right cone portion 22 are connected to the bottom of the left and right sides of the upper cylinder 1 respectively. In the two adjacent lower cones 2, the top of the rear cone portion 24 of the lower cone 2 located on the front side is connected to the top of the front cone portion 23 of the lower cone 2 located on the rear side. The left cone portion 21 and the right cone portion 22 of the lower cone 2 located on the front side are connected to the left cone portion 21 and the right cone portion 22 of the lower cone 2 located on the rear side respectively. That is, all the lower cones 2 and the upper cylinder 1 form a structure with openings on both the front and rear sides.

[0049] It should be noted that the front cone portion 23 of the front cone 2a extends upward to the top of the left cone portion 21 and the right cone portion 22.

[0050] Each lower cone 2 also includes a fluidizing section 25, which is located at the bottom of the overall structure formed by the left cone section 21, the right cone section 22, the front cone section 23 and the rear cone section 24. The fluidizing section 25 is inverted cone shape and has a discharge port at its apex.

[0051] Optionally, each fluidization section 25 is provided with multiple nozzles 8 spaced apart along the circumference. Each nozzle 8 is connected to an external compressed air source and is used to spray compressed gas into the downward cone 2 so that the material in the fluidization section 25 can smoothly slide down to the discharge port under the action of the airflow, thereby increasing the material discharge speed and reducing the discharge residue rate.

[0052] It should be noted that the aforementioned external compressed air source can come from the compressed air supply equipment on the tanker truck used for transporting the tank, or from a compressed air supply equipment located at an external work site (e.g., the material unloading destination). This compressed air supply equipment can be an air compressor, a compressed gas storage tank, etc. This application does not improve the structure or supply principle of the compressed air supply equipment; all can refer to relevant existing technologies, as long as compressed gas can be delivered into the downward cone 2.

[0053] Figure 3 for Figure 1 Schematic diagram of the directional structure at point B.

[0054] refer to Figures 1-3 In this embodiment, the front end cap 3 is fixed between the front end of the upper cylinder 1 along the axial direction and the front end of the front cone 2a, and is used to close the opening formed by the front end of the upper cylinder 1 and the front end of the front cone 2a, so that a closed space can be formed inside the tank. Compared with the prior art, where the front end cap 3 needs to be connected to the upper cylinder 1 and the front cone 2a through a transition conical section, the above design eliminates the setting of the transition conical section which is constricted from back to front. Instead, the front end cap 3 is directly set at the opening formed by the front end of the upper cylinder 1 and the front end of the front cone 2a after the constriction of the transition conical section. This is beneficial to increase the size of the front end cap 3 in the left and right direction, so that while keeping the overall height of the tank unchanged, the space in the left and right direction of the upper cylinder 1 and the front side of the front cone 2a can be rationally utilized to increase the volume of the front end cap 3, thereby increasing the volume of the tank. This allows the tank to hold more material at a time, increasing the material transport capacity and the efficiency of a single transport. Furthermore, compared to existing technologies, the above design can reduce the axial dimensions of the tank while keeping the total tank volume unchanged. In addition, the above design can reduce the number of annular welds at the front of the tank, which can reduce the resistance to material sliding, shorten the unloading time, and also improve the production efficiency of the tank.

[0055] The front end cap 3 is arranged from top to bottom and backward, and its tilt angle is consistent with the tilt angle of the front end face of the peripheral wall of the front cone 2a. This facilitates a smooth transition between the front end cap 3 and the front cone 2a, and allows the material to slide down the inner surface of the peripheral wall of the front end cap 3 to the front cone 2a, thereby improving the smoothness of material flow during unloading and increasing the unloading speed.

[0056] Specifically, the inclination angle of the front end cap 3 is greater than 40°, that is, the acute angle α formed by the front end cap 3 and the horizontal plane is greater than 40°. This design ensures that its inclination angle is equal to the inclination angle of the peripheral wall of the lower cone 2, and is also greater than the material repose angle, so that the material can slide down from the inner surface of the peripheral wall of the front end cap 3 to the front cone 2a. At the same time, it is beneficial to expand the volume of the tank and maximize the volume of the tank.

[0057] Optionally, the maximum dimension of the front end cap 3 in the left-right direction is the maximum dimension of the tank body in the left-right direction. That is, the left and right ends of the front end cap 3 can extend to cover the maximum dimension in the left-right direction of the tank body. This makes reasonable use of the space in the left-right direction of the upper cylinder 1 and the front cone 2a, which helps to increase the volume of the front end cap 3 while keeping the overall height of the tank body unchanged. This increases the volume of the tank body, allowing the tank body to hold more material at a time, increasing the material transport capacity and improving the efficiency of a single transport.

[0058] Since the upper cylinder 1 is a semi-elliptical shape with its opening facing downwards, and the lower cone 2 gradually narrows in diameter from top to bottom, the dimensions of the bottom of the upper cylinder 1 and the top of the lower cone 2 in the left-right direction are the maximum dimensions of the tank in the left-right direction.

[0059] Optionally, the maximum dimension of the front end cap 3 in the left-right direction is greater than 2m.

[0060] The top of the front end cap 3 is lower than the top of the upper cylinder 1. Optionally, the tank also includes a transition plate 5, which connects the front end face of the upper cylinder 1 and the rear side face of the front end cap 3. The transition plate 5 is arranged downward from back to front to connect the front end cap 3 and the upper cylinder 1.

[0061] Specifically, due to the inclined arrangement of the front end cap 3, the rear side of the front end cap 3 tilts forward from bottom to top and gradually moves away from the front side of the upper cylinder 1. Therefore, the rear side of the front end cap 3 is connected to the upper cylinder 1 and the transition plate 5 to seal the gap between the front end cap 3 and the upper cylinder 1, so that a sealed space is formed inside the tank.

[0062] Optionally, the axial dimension of the portion connecting the front end cap 3 to the upper cylinder 1 is smaller than the axial dimension of the portion connecting the front end cap 3 to the transition plate 5. The front end face of the upper cylinder 1 extends vertically. With the height difference between the top of the front end cap 3 and the top of the upper cylinder 1 remaining constant, this design facilitates increasing the axial dimension of the transition plate 5 in the upper cylinder 1, thereby reducing the inclination slope of the transition plate 5 and improving the streamlined appearance of the outer tank.

[0063] The outer contour of the front end cap 3 includes a first arc-shaped edge 31 and a second arc-shaped edge 32, both of which are arc-shaped.

[0064] The first arc-shaped edge 31 is connected between the two opposite ends of the second arc-shaped edge 32. The first arc-shaped edge 31 is located above the rear side of the second arc-shaped edge 32. The concave surface of the first arc-shaped edge 31 faces downward. The first arc-shaped edge 31 is connected to the front end of the upper cylinder 1 and the transition plate 5.

[0065] The concave surface of the second arc-shaped edge 32 faces the first arc-shaped edge 31 along the axial direction of the upper cylinder 1, and the second arc-shaped edge 32 is connected to the front end of the front cone 2a. Specifically, the second arc-shaped edge 32 is connected to the top of the front end of the front cone portion 23 of the front cone 2a.

[0066] Specifically, the plane containing the first arc-shaped edge 31 slopes backward from top to bottom, and the plane containing the second arc-shaped edge 32 slopes backward from bottom to top. The plane containing the first arc-shaped edge 31 and the plane containing the second arc-shaped edge 32 are perpendicular to each other.

[0067] In this embodiment, the front end cap 3 has a concave surface with an opening facing rearward. The cross-section of the front end cap 3 is semi-elliptical, and the diameter of the front end cap 3 in the left-right direction is larger than its diameter in the up-down direction. The diameter of the front end cap 3 in the left-right direction is the maximum dimension of the tank body in the left-right direction.

[0068] In this embodiment, the front end cap 3 is stamped, which helps to improve the structural strength of the front end cap 3 and enhance its pressure-bearing capacity.

[0069] refer to Figure 1 and Figure 2 In this embodiment, the rear end cap 4 is connected to the rear end of the upper cylinder 1 and the rear end of the rear cone 2b to close the opening formed by the rear ends of the upper cylinder 1 and the rear cone 2b.

[0070] The rear end cap 4 has an elliptical cross-section, and its diameter in the left-right direction is larger than its diameter in the up-down direction. The rear end cap 4 has a concave surface that opens forward.

[0071] According to another aspect of this application, a tank truck is also provided, including a vehicle body and a tank as described above. The tank is mounted on the vehicle body, which can be a semi-trailer, enabling the transport of the tank via the vehicle body.

[0072] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the front end cap is directly fixed between the front end of the upper cylinder and the front end of the front cone along the axial direction. Compared with the prior art, where the front end cap needs to be connected to the upper cylinder and the front cone through a transition conical section, the above design eliminates the setting of the transition conical section that narrows from back to front. Instead, the front end cap is directly set at the opening formed by the front ends of the upper cylinder and the front cone after the transition conical section has not narrowed. This is beneficial to increase the size of the front end cap in the left and right directions. Thus, while ensuring that the overall height of the tank remains unchanged, the space in the left and right directions of the upper cylinder and the front side of the front cone can be reasonably utilized to increase the volume of the front end cap, thereby increasing the volume of the tank. This allows the tank to hold more material at a time, increasing the material transport capacity and improving the efficiency of a single transport. Furthermore, compared to existing technologies, the above design can reduce the axial dimensions of the tank while keeping the total tank volume unchanged. In addition, the above design can reduce the number of annular welds at the front of the tank, which can reduce the resistance to material sliding, shorten the unloading time, and also improve the production efficiency of the tank.

[0073] Furthermore, the front end cap is arranged at an angle, and the angle of inclination is consistent with the angle of inclination of the front end face of the peripheral wall of the front cone. This facilitates a smooth transition between the front end cap and the front cone, and allows the material to slide down the inner surface of the peripheral wall of the front end cap to the front cone, thereby improving the smoothness of material flow during unloading and increasing the unloading speed.

[0074] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
