[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 tanks 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 with a large volume.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The inner peripheral walls of each of the lower cones are inclined inward from top to bottom. The one located at the front of all the lower cones is the front cone. The inclination angle of the rear end face of the inner peripheral wall of the front cone is equal to the inclination angle of the inner peripheral walls of the other lower cones. The inclination angle of the front end face of the inner peripheral wall of the front cone is smaller than the inclination angle of the inner peripheral walls of the other lower cones.

[0008] In some embodiments, the inclination angle of the inner peripheral wall of the front cone and the inclination angle of the inner peripheral walls of the remaining lower cones are both greater than the angle of repose of the material.

[0009] In some embodiments, the inclination angle of the rear end face of the inner peripheral wall of the front cone is 45°, and the inclination angle of the remaining lower cones is 45°.

[0010] The inclination angle of the front end face of the inner peripheral wall of the front cone is 30°.

[0011] In some embodiments, the front end of the front cone is provided with an air inlet communicating with its interior, and each air inlet is connected to an external air source through an air inlet pipe, the air inlet pipe being connected to the outside of the front cone.

[0012] In some embodiments, each of the lower cones is provided with an air inlet at its bottom, and each air inlet is used to communicate with an external air source;

[0013] The air inlet pipe includes a main pipe and multiple branch pipes. The main pipe has connectors at both ends, and each connector is used for detachable connection with an external air source. The multiple branch pipes are connected to the main pipe, and each air inlet and air outlet is connected to one of the branch pipes.

[0014] A control valve is provided at the connection point between each branch pipe and the main pipe, and the control valve is used to control the opening and closing of the corresponding branch pipe.

[0015] In some embodiments, the tank body further includes an extension cylinder disposed at the front end of the upper cylinder body;

[0016] The extension tube includes a cylindrical body and a transition section located at the lower part of the cylindrical body. The cylindrical body is connected to the front end of the upper cylindrical body, and the transition section is connected to the front end of the front cone. The bottom wall of the transition section is inclined from top to bottom toward the front cone.

[0017] In some embodiments, all of the lower cones further include a rear cone and at least two middle cones located between the front cone and the rear cone;

[0018] The bottom of the front cone is flush with the bottom of the middle cone; the bottom of the rear cone extends upward beyond the bottom of the middle cone.

[0026] In this invention, the inclination angle of the front end of the inner circumferential wall of the front cone is set to be smaller than the inclination angle of the inner circumferential walls of the other lower cones. This design increases the cone angle of the front cone, which allows for the rational use of the space between the front of the tank and the tanker truck body in the axial direction of the tank while keeping the overall height of the tank unchanged. This increases the volume of the front cone, thereby increasing the volume of the tank and enabling the tank to hold more material at a time, thus increasing the material transport capacity and improving the efficiency of a single transport.

Therefore, features defined as "middle" or "outer" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] This application provides a tank for holding materials to facilitate the storage and transportation of materials.

[0043] The material can be in the form of spherical or cylindrical particles.

[0044] The following detailed description of specific embodiments of the tank body of this application is provided in conjunction with the accompanying drawings.

[0045] 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.

[0046] refer to Figure 1 The tank body 100 includes an upper cylinder 1 and a plurality of lower cones 2 arranged sequentially along the axial direction of the upper cylinder 1 and disposed below the upper cylinder 1. The inner 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 21. The inclination angle of the rear end face of the inner peripheral wall of the front cone 21 is equal to the inclination angle of the inner peripheral walls of the other lower cones 2, and the inclination angle of the front end face of the inner peripheral wall of the front cone 21 is smaller than the inclination angle of the inner peripheral walls of the other lower cones 2.

[0047] In this application, the inclination angle of the front end face of the inner peripheral wall of the front cone 21 is set to be smaller than the inclination angle of the inner peripheral wall of the other lower cones 2. This design increases the cone angle of the front cone 21. This allows for the efficient use of the space at the front of the tank 100 while maintaining the overall height of the tank 100, thereby increasing the volume of the front cone 21 and thus the volume of the tank 100. This increases the effective loading capacity of the tank 100, enabling it to hold more material at a time, improving the amount of material transported per trip, and increasing the efficiency of each trip.

[0048] In this paper, the axial direction of the tank 100 is the front-to-back direction, and the direction perpendicular to the axial direction of the tank 100 in the same horizontal plane is the left-to-right direction.

[0049] It should be noted that, taking the vertical plane where the center line of the front cone 21 is located as the reference, this vertical plane extends to the left and right and intersects with the left and right sides of the front cone 21. This vertical plane is the interface between the front end face and the rear end face of the inner peripheral wall of the front cone 21.

[0050] The inclination angle of the inner peripheral 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.

[0051] refer to Figure 1 and Figure 2 The tank body 100 includes an upper cylindrical body 1 and multiple lower conical bodies 2.

[0052] The upper cylinder 1 has a semi-elliptical cross-section, and its diameter in the left-right direction is larger than its diameter in the up-down direction. Compared to a circular structure, the semi-elliptical shape has a wider width, which increases the width of the upper part of the entire tank 100. 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 volume of the entire tank 100, that is, increasing the effective loading capacity of the tank 100, and thus improving the single transport capacity of the tanker.

[0053] A manhole is provided at the top of the upper cylinder 1, through which materials can be loaded into the tank 100. Optionally, a manhole cover 4 is provided at the manhole, which is used to open and close the manhole.

[0054] 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.

[0055] 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.

[0056] Each lower cone 2 has a discharge port 24 at its bottom for unloading materials from the tank 100. Specifically, the lower cone 2 located at the front is the front cone 21. The multiple lower cones 2 also include a rear cone 22 and at least two middle cones 23 located between the front cone 21 and the rear cone 22. The bottom of the front cone 21, each middle cone 23 and the rear cone 22 are respectively provided with a discharge port 24.

[0057] Optionally, each of the 24 discharge ports is connected to a discharge pipe 200.

[0058] Figure 3 This is a schematic diagram of the arrangement of the unloading pipe 200 in this embodiment.

[0059] refer to Figure 3 The discharge pipe 200 is connected and fixed to the outside of the tank body 100 via the connecting bracket 7. The discharge pipe 200 extends to the outside of the tank body 100 in the left-right direction to facilitate the discharge operation. Each pair of adjacent lower cones 2 forms a group and can share one discharge pipe 200, or each lower cone 2 can have its discharge port connected to a separate discharge pipe 200, depending on actual needs. The discharge pipe 200 is equipped with a discharge valve 6 for controlling its on / off state.

[0060] refer to Figure 1 Optionally, the inner peripheral walls of each lower cone 2 are inclined inward from top to bottom, that is, the diameter of the 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 24 of the lower cone 2, which is more conducive to unloading.

[0061] Specifically, each lower cone 2 is cone-shaped, with its peripheral sidewalls inclined inwards from top to bottom. That is, the inclination angles of the inner and outer sides of the peripheral sidewalls of each lower cone 2 are the same, meaning the inclination angles of the inner and outer peripheral walls of each lower cone 2 are the same. This saves material in manufacturing the lower cones 2, reduces their weight, and facilitates both improved material unloading and a lighter tank body 100. Furthermore, since the diameter of each lower cone 2 gradually decreases from top to bottom, each lower cone 2 is in an inverted position with its apex facing downwards. Additionally, the centerline of each lower cone 2 extends upwards from its bottom apex, i.e., vertically.

[0062] In this design, the inclination angle α of the rear end face of the inner peripheral wall of the front cone 21 is equal to the inclination angle β of the inner peripheral wall of the other lower cones 2, and the inclination angle γ of the front end face of the inner peripheral wall of the front cone 21 is smaller than the inclination angle β of the inner peripheral wall of the other lower cones 2. This design increases the cone angle of the front cone 21, which allows for the rational use of the space at the front of the tank 100 while keeping the overall height of the tank 100 unchanged, thereby increasing the volume of the front cone 21 and thus increasing the volume of the tank 100. This increases the effective loading capacity of the tank 100, enabling it to hold more material at a time, improving the single transport volume of material, and increasing the efficiency of single transport.

[0063] Specifically, the inclination angle of the inner peripheral wall of all the middle cones 23 is equal to the inclination angle of the inner peripheral wall of the rear cone 22, the inclination angle of the rear end face of the inner peripheral wall of the front cone 21 is equal to the inclination angle of the inner peripheral wall of the middle cone 23, and the inclination angle of the front end face of the inner peripheral wall of the front cone 21 is less than the inclination angle of the inner peripheral wall of the middle cone 23.

[0064] The inclination angle of the inner peripheral wall of the front cone 21 and the inclination angle of the inner peripheral walls of the other lower cones 2 are both greater than the angle of repose of the material. This design allows the inner peripheral walls of each lower cone 2 to have a large inclination angle, which can reduce the contact stress between the material and the inner peripheral wall of the lower cone 2, making it easier for the material to slide down along the inner 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.

[0065] 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°.

[0066] For example, the inclination angle of the rear end face of the inner peripheral wall of the front cone 21 is 45° and the inclination angle of the remaining lower cones 2 are 45°, and the inclination angle of the front end face of the inner peripheral wall of the front cone 21 is 30°. This design ensures that the inclination angle of the inner peripheral wall of the front cone 21 and each lower cone 2 is greater than the material repose angle, while expanding the volume of the front cone 21 through different angle designs, so as to maximize the volume of the tank 100.

[0067] Optionally, an air inlet 25 communicating with the interior is provided at the front end of the front cone 21, and each air inlet 25 is connected to an external air source. Since the inclination angle of the front end face of the inner peripheral wall of the front cone 21 approaches the angle of repose of the material, through the above design, gas can be introduced into the interior of the front cone 21, so that the material at the front end of the inner side wall of the front cone 21 can smoothly slide down to the bottom discharge opening 24 under the action of the air flow, improving the discharge speed of the material and reducing the discharge residue rate.

[0068] Reference Figure 1 , optionally, air inlets 26 are respectively provided at the bottoms of the lower cones 2, and each air inlet 26 is used to communicate with an external air source. Through the above design, gas can be introduced into the interiors of the lower cones 2, so that the material in each lower cone 2 can smoothly slide down to the bottom discharge opening 24 under the action of the air flow, improving the discharge speed of the material and reducing the discharge residue rate.

[0069] Reference Figure 1 , the bottom of the front cone 21 is flush with the bottom of the middle cone 23, and the bottom of the rear cone 22 extends upward beyond the bottom of the middle cone 23. The intervals between the vertices of two adjacent lower cones 2 are not equal, that is, the shortest distances between the centerlines of two adjacent lower cones 2 are not equal.

[0070] Specifically, the relationship between the interval distance L1 between the vertex of the front cone 21 and the vertex of the adjacent middle cone 23, the interval distance L2 between the vertices of two adjacent middle cones 23, and the interval distance L3 between the vertex of the adjacent middle cone 23 and the vertex of the rear cone 22 is: L1 < L2 < L3. In this way, on the basis that each lower cone 2 satisfies the foregoing conditions, the overall formed by all the lower cones 2 can have the largest volume, achieving the maximization of the effective volume of the tank body 100.

[0071] Reference Figure 1 , the tank body 100 further includes an extension cylinder 3 provided at the front end of the upper cylinder 1. The design of the extension cylinder 3 can extend the axial length of the tank body 100. In this way, without changing the overall height of the tank body 100 and the length of the vehicle body 400 of the tank truck 400, the space between the front part of the tank body 100 and the vehicle body 400 of the tank truck 4 on the axial direction of the tank body 100 can be further reasonably utilized to increase the volume of the tank body 100, improve the effective loading capacity of the tank body 100, and increase the single transportation volume of the tank body 100.

[0072] The extension cylinder 3 includes a cylinder part 31 and a transition part 32 located below the cylinder part 31. Among them, the cylinder part 31 is connected to the front end of the upper cylinder 1, and the transition part 32 is connected to the front end of the front cone 21. The bottom wall of the transition part 32 inclines downward toward the front cone 21 from top to bottom. Specifically, the inclination angle of the bottom wall of the transition part 32 is the same as the inclination angle of the front end face of the inner peripheral wall of the front cone 21.

[0073] Optionally, the bottom wall of the transition section 32 is also provided with an air inlet 25 that communicates with its interior. The air inlet 25 is used to connect with an external air source. Through the above design, gas can be introduced into the extension cylinder 3, so that the material in each extension cylinder 3 can smoothly slide down to the bottom discharge port 24 of the front cone 21 under the action of airflow, thereby improving the material discharge speed and reducing the discharge residue rate.

[0074] Figure 4 This is a schematic diagram showing the arrangement of the air inlet duct 300 in this embodiment. Figure 5 This is a schematic diagram of the air inlet pipe 300 in this embodiment.

[0075] refer to Figure 4 and Figure 5 Each air inlet 25 on the front cone 21 and each air inlet 26 on the lower cone 2 are connected to an external air source through an air inlet pipe 300. The air inlet pipe 300 is connected to the outside of the front cone 21.

[0076] For example, the air inlet duct 300 includes a main duct 301 and multiple branch ducts. The main duct 301 extends longitudinally along its length, with its rear end connected to the outer side of the front cone 21, and its front end protruding forward beyond the front cone 21. Specifically, multiple connectors 311 are spaced apart on the main duct 301, each connector 311 connecting to the outer side of the front cone 21 to secure the main duct 301.

[0077] The main pipeline 301 is provided with connectors 304 at its two opposite ends in the front and rear directions. Each connector 304 can be detachably connected to the pipeline of an external gas source. In actual application, one of the two connectors 304 is connected to the external gas source so that the gas from the external gas source can enter the main pipeline 301. The operation is convenient and simple.

[0078] It should be noted that the external air source in this article can come from the compressed air supply equipment built into the tanker truck body 400 used to transport the tank 100, or from a compressed air supply equipment located at an external work site (e.g., the material unloading destination). Specifically, the connector 304 located at the front end of the main pipeline 301 is connected to the output end of the compressed air supply equipment built into the tanker truck body 400, so that the main pipeline 301 can be connected to the output end of the compressed air supply equipment built into the tanker truck body 400; the connector 304 located at the rear end of the main pipeline 301 is used to connect to the output end of the compressed air supply equipment at the external work site, so that the main pipeline 301 can be connected to the output end of the compressed air supply equipment at the external work site. In practical applications, any connector 304 can be selected to connect and communicate with the corresponding compressed air supply equipment's output end as needed, which has high practicality.

[0079] It should be noted that the above-mentioned compressed gas supply equipment can be an air compressor, a compressed gas storage tank, etc. This application does not improve the structure or gas supply principle of the compressed gas supply equipment. All of these can be referred to the relevant existing technologies, as long as they can deliver compressed gas into the air inlet pipe 300.

[0080] The front connector 304 is tilted forward from bottom to top to avoid interference from the tank body 100, allowing for a detachable connection between the connector 304 and the output end of the compressed air supply equipment on the tanker vehicle body 400. The rear connector 304 is tilted downward from top to bottom and laterally away from the tank body 100 to avoid interference from the tank body 100, allowing for a detachable connection between the connector 304 and the output end of the compressed air supply equipment at the external work site.

[0081] It should be noted that the connector 304 at the front end can maintain a physical connection with the output end of the compressed air supply equipment on the tanker body 400 as needed.

[0082] Optionally, a check valve 312 is provided at the front end of the main pipeline 301. The check valve 312 is a one-way valve, so that compressed gas can only flow from front to back in the main pipeline 301 to pass through the check valve 312. In addition, a switch valve 305 is provided at the rear end of the main pipeline 301 for controlling its opening and closing. If compressed gas is required from the compressed gas supply equipment on the tanker body 400, the output end of the compressed gas supply equipment's pipeline is connected to the connector 304 at the front end of the main pipeline 301, and the switch valve 305 is closed to keep the rear end of the main pipeline 301 closed. If compressed gas is required from the compressed gas supply equipment at the external work site, the connector 304 at the rear end of the main pipeline 301 is connected to the output end of the compressed gas supply equipment at the external work site, and the switch valve 305 is opened. Under the action of the check valve 312, the compressed gas flowing from back to front in the main pipeline 301 cannot pass through the check valve 312. That is, this makes the main pipeline 301 at the rear of the check valve 312 disconnected from the output end of the compressed gas supply equipment's pipeline on the tanker body 400.

[0083] The main pipeline 301 includes at least one inclined section 3011 and at least one horizontal section 3012. The inclined section 3011 slopes backward from top to bottom, and the horizontal section 3012 extends forward and backward. Specifically, the main pipeline 301 includes two inclined sections 3011 and two horizontal sections 3012, with the inclined sections 3011 and horizontal sections 3012 alternating. That is, the configuration of the main pipeline 301 (from front to back) is: inclined section 3011 - horizontal section 3012 - inclined section 3011 - horizontal section 3012. A connector 304 is provided at the front end of the inclined section 3011, which is conveniently arranged to accommodate the height of the compressed air supply equipment pipeline on the tanker body 400. A connector 304 is located at the rear end of the horizontal section 3012. With the help of the two inclined sections 3011, the horizontal section 3012 can be lowered in the vertical direction, facilitating operation and allowing for detachable connection between the connector 304 on the horizontal section 3012 and the compressed air supply equipment in the external work area. A check valve 312 is located on the front horizontal section 3012, and a switch valve 305 is located at the rear end of the horizontal section 3012.

[0084] Multiple branch pipes are connected to the main pipe 301, and each air inlet 25 and each air inlet 26 are connected to a branch pipe, so that compressed gas can sequentially enter the interior of each lower cone 2 through the main pipe 301, the branch pipes, and the air inlet 25 or air inlet 26. Optionally, each branch pipe can be a flexible hose, giving it a certain degree of flexibility to bend and adapt to the external shape of the front cone 21, thus facilitating the arrangement of the branch pipes. Specifically, each branch pipe is connected to the rear horizontal section 3012 of the main pipe 301, and all branch pipes are located in front of the switch valve 305 and behind the check valve 312. The connection method between the branch pipes and the tank 100 can refer to the connection method between the main pipe 301 and the front cone 21 described above.

[0085] Optionally, a control valve 306 is provided at the connection point between each branch pipe and the main pipe 301. The control valve 306 is used to control the opening and closing of the corresponding branch pipe.

[0086] The air inlet duct 300 also includes a branch duct 303, which is connected to the main duct 301. The branch duct 303 is equipped with a valve 307 to control its on / off state, thus enabling the connection between the branch duct 303 and the main duct 301. The branch duct 303 extends upwards along the outside of the tank 100 to the top of the tank 100 and connects with the top of the tank 100. It is used to introduce compressed gas into the tank 100 to increase the internal pressure, thereby improving the speed and smoothness of material unloading. It also allows for purging of the tank 100 after unloading. Specifically, the branch duct 303 is connected to the front end of the horizontal section 3012 of the main duct 301, located at the rear side. The connection point between the branch duct 303 and the main duct 301 is located at the front side of all branch ducts and at the rear side of the check valve 312. The connection method between the branch duct 303 and the tank 100 can be referenced to the connection method between the main duct 301 and the front cone 21 described above.

[0087] Optionally, a pressure sensor 308 is provided on the branch pipe 303 to detect the pressure value inside the branch pipe 303. A connector 310 may also be connected to the branch pipe 303, extending downward relative to the branch pipe 303 for communication with an external air source. That is, the pipeline connected to the external air source can be selected through the connector 310 as needed, and / or the valve 307 can be opened to allow the branch pipe 303 to communicate with the main pipe 301.

[0088] Optionally, a pressure detector 309 is provided on the air inlet pipe 300 to detect the pressure value inside the air inlet pipe 300. Since the air inlet pipe 300 is connected to each lower cone 2, the pressure inside the tank 100 can be determined by observing this pressure value. When the pressure value reaches a preset value, at least one discharge valve 6 is operated as needed to open at least one discharge port 24 for discharge operation. It should be noted that this preset value is determined according to the actual situation of the material to enable the material to achieve fluidization.

[0089] Figure 6 This is a schematic diagram of the tanker truck in this embodiment.

[0090] refer to Figure 6 This application also provides a tank truck, including a vehicle body 400 and a tank body 100 as described above.

[0091] The tank 100 is mounted on the vehicle body 400, which can be a semi-trailer. The vehicle body 400 enables the transportation of the tank 100. Specifically, the vehicle body 400 includes a frame and a cab located at the top front of the frame, with the tank 100 mounted on the frame.

[0092] The tanker also includes two support bodies 500, which are respectively located at the bottom of the front and rear ends of the tank body 100. Each support body 500 is supported between the top of the frame and the bottom of the tank body 100, improving the stability of the tank body 100. Specifically, one support body 500 is supported between the bottom of the extension tube 3 and the top of the frame, and also between the outer sidewall of the front cone 21 and the top of the frame, so that the support body 500 has a large contact area with the tank body 100, which can improve the support stability of the tank body 100. At this time, the front end of the air inlet pipe 300 protrudes forward from the front cone 21 and is connected to the outer periphery of the support body 500 through the connector 311. The other support body 500 is supported between the outer sidewall of the rear cone 22 and the top of the frame.

[0093] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0094] In this invention, the inclination angle of the front end face of the inner peripheral wall of the front cone is set to be smaller than the inclination angle of the inner peripheral walls of the other lower cones. This design increases the cone angle of the front cone, which allows for the rational use of the space between the front of the tank and the tanker truck body in the axial direction of the tank while keeping the overall height of the tank unchanged. This increases the volume of the front cone, thereby increasing the volume of the tank and enabling the tank to hold more material at a time, thus increasing the material transport capacity and improving the efficiency of a single transport.

[0095] Furthermore, the design of the extension tube can extend the axial length of the tank. This allows for more efficient use of the space between the front of the tank and the tanker truck in the axial direction of the tank, while ensuring that the overall height of the tank and the length of the truck remain unchanged. This increases the tank's volume, effective loading capacity, and single-trip transport capacity.

[0096] Furthermore, by setting an air inlet at the front end of the front cone for communication with an external air source, gas can be introduced into the front cone, allowing the material at the front end of the inner wall of the front cone to slide smoothly down to the bottom discharge port under the action of airflow, thereby increasing the material discharge speed and reducing the discharge residue rate.

[0097] 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.
