Description

[0001] The present application is a divisional application of the invention entitled "Tanker, tank body, barrel section, half barrel section and forming method of tank body", the original application date is July 1, 2022, and the original application number is 2022107653785. TECHNICAL FIELD

[0002] The present application relates to the technical field of special vehicles, in particular to a tanker and a tank body. BACKGROUND

[0003] At present, powdery materials are usually transported by tank bodies. Tank bodies are usually divided into vertical tank bodies and horizontal tank bodies according to different unloading methods. Both horizontal tank bodies and vertical tank bodies include a circular barrel at the upper part and an unloading structure arranged at the bottom of the circular barrel. The unloading structure of the horizontal tank body is usually V-shaped or W-shaped. The slope formed by the V-shaped or W-shaped unloading structure guides the flow of the material to the unloading port at the bottom to achieve unloading. However, the inclination angle of the V-shaped or W-shaped unloading structure is limited. For powdery materials with good fluidization performance, unloading can still be achieved, but for materials with poor fluidization performance, it is difficult to achieve unloading. In order to adapt to materials with different fluidization performance, improve the unloading speed and reduce the unloading residual amount, vertical tanks are developed. The vertical tank usually includes a circular barrel and a plurality of (usually more than four) cylindrical cones arranged in sequence along the axial direction at the bottom of the circular barrel. The bottom of each cone forms an open port, which serves as an unloading port, so that the vertical tank forms a plurality of chambers for separate unloading. Each chamber uses the super large inclination angle of the outer surface of the cylindrical cone to achieve rapid unloading, solving the unloading problem of materials with poor fluidization performance.

[0004] However, in the production process of the vertical tank body, the traditional process is to first prepare a barrel, then open a plurality of openings at the bottom of the barrel, then insert the large end of each cylindrical cone prepared in advance into the corresponding opening, and then weld the cone and the barrel to obtain the tank body. However, when the cone is welded with the barrel, since the weld is located on the inner side of the barrel, the operator needs to enter the barrel for operation, which is not convenient, resulting in low welding efficiency, and further resulting in low production efficiency of the entire tank body. At the same time, when the cone is connected with the barrel, some additional connecting structures need to be added to connect the two. The above connecting structures are usually located inside the tank body, which not only reduces the effective volume inside the tank body, but also blocks the flow of the material inside the tank body to the bottom of the cone, causing the tank body to have unloading dead angles and resulting in incomplete unloading. SUMMARY

[0005] The purpose of the present application is to provide a tanker and a tank body to solve the problems of low production efficiency of the tank body, low effective volume inside the tank body and incomplete unloading in the prior art.

[0008] In one embodiment, a transition surface is pressed at the junction of the first unit and the second unit before the blanking plate is wound and formed.

[0009] In one embodiment, the thickness of the blanking plate at the drawing extension position is greater than that at other positions; or,

[0010] The blanking plate is a flat plate with uniform thickness, and a reinforcing plate is arranged on the inner side of the drawing extension position of the blanking plate.

[0011] In one embodiment, the tank body further comprises a transition cylinder section, the transition cylinder section comprises a cylinder section and a transition section, the cylinder section is connected with the first unit of the adjacent cylinder section, the bottom surface of the transition section is inclined towards the adjacent cylinder section, and the transition section is connected with the second unit of the adjacent cylinder section.

[0012] In one embodiment, the cylinder section is a closed ring, the transition section is located inside the cylinder section and connected with the inner wall of the cylinder section; the transition section comprises two inclined surfaces which are arranged at an acute angle with respect to each other, and the joint of the two inclined surfaces is arched to form a sharp corner with respect to the inner wall of the cylinder section; or the transition section comprises an inclined surface which is inclined from one side of the cylinder section to the other side.

[0017] The application further provides a tank truck, which comprises a frame and a tank body arranged on the frame, and the tank body is the tank body as described above.

[0018] According to the above technical solution, the application has the following advantages and positive effects:

[0019] The application forms the cylinder section with a cylindrical cone of different square amounts by grouping the overall structure of the tank body according to different square amounts and different specifications, then horizontally arranging and combining the cylinder sections of different square amounts to form the tank body of different square amounts, and finally welding each section of the cylinder section to form the overall tank body. When the cylinder section is formed, the cylinder section is divided into two parts according to the axis of symmetry of the cone, and the two parts are formed into two half cylinder sections, and then the two half cylinder sections are butt-welded into one cylinder section, which greatly simplifies the forming difficulty of the single cylinder section, and optimizes the cross section of the single cylinder section, so that the two ends of the single cylinder section are both circular rings with the same size. Therefore, when the adjacent cylinder sections are welded, only the adjacent cylinder sections need to be welded by the ring seam welding method, which improves the standard universality of the production process, facilitates the mechanized automatic welding, and improves the production efficiency of the tank body. Secondly, by horizontally combining different cylinder sections and using the longitudinal ring seam welding method, the product welding quality is effectively improved, thereby improving the overall quality of the product. Thirdly, by arranging and combining the square amounts of the standard universal cylinder sections of various specifications, the structure form of the product series standardization is effectively improved, and the product design and management efficiency is improved. Finally, by using the ring seam welding of the standard universal cylinder sections of various specifications, various defects such as non-standard, non-standard, uneven joint, high welding labor intensity, high splicing riveting difficulty, and poor product welding quality caused by the splicing welding of the traditional cylinder and the cone can be effectively avoided.

[0020] In addition, the application also realizes the integral forming of each half cylinder section by optimizing the forming process through a blanking plate, which greatly improves the production efficiency, facilitates the mechanized large-scale production, reduces the labor intensity and safety hazards of workers, and also reduces the labor cost.

[0021] The forming method of the half cylinder section and the forming method of the cylinder section do not have the phenomenon that the effective space for loading materials in the tank body is reduced due to the increased plate material when the cylindrical structure and the conical structure are spliced and welded, which effectively improves the utilization rate of the tank body volume and reduces the overall weight of the tank body. Since the inside of the cylinder section is smooth, the materials can flow smoothly to the bottom of the cone of each cylinder section, and there is no dead angle for unloading, so the unloading is clean and fast.

[0091] The features and advantages of the present application will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:

[0092] To further illustrate the principles and architectures of the present application, preferred embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings.

[0093] The present application provides a tank car for transporting powder materials. The powder materials are, for example, chemical powder materials and food powder materials.

[0094] The tank car comprises a frame and a tank body on the frame.

[0095] The tank body structure of the present application is particularly suitable for vertical tank bodies.

[0096] For the convenience of description, the length direction of the frame is defined as the longitudinal direction, the width direction of the frame is defined as the transverse direction, the direction close to the head is defined as the front direction, and the direction away from the head is defined as the rear direction.

[0097] The tank body comprises at least two cylinder segments.

[0098] The present application groups different specifications of the overall structure of the tank body according to different volumes, forms standard universal cylinder segments with a cylindrical cone of different volumes, then arranges and combines the cylinder segments of different volumes in the transverse direction to form tank bodies of different volumes, and finally performs girth welding on each cylinder segment of the combined tank body to form an overall tank body.

[0099] The tank body of the present application not only has high production efficiency and is convenient to form, but also has a large effective loading rate. The tank body will be described below through specific embodiments.

[0100] First embodiment of the tank body

[0101] Figure 1 Fig. 1 shows a structure schematic diagram of the tank body 1 in the present embodiment, Figure 2 Fig. 2 shows a front view of the tank body 1 in the present embodiment, Figure 3 Fig. 3 shows a bottom view of the tank body 1 in the present embodiment, Figures 4-11 Fig. 4 shows an effect diagram of the tank body 1 in the present embodiment, which is combined withFigures 1-11 The tank body 1 comprises a plurality of barrel segments 11. The plurality of barrel segments 11 are arranged in transverse direction and connected end to end to form the tank body 1. Each barrel segment 11 has a discharge hole 12 at the bottom for discharging materials.

[0102] Among the plurality of barrel segments 11, the barrel segments at the ends are end barrel segments. In order to meet the volume requirement of the tank body 1 and the requirement of matching the tank body 1 with the frame, the barrel segments at the ends can adopt non-standard barrel segments, and the remaining barrel segments can adopt standard barrel segments in the present application.

[0103] The upper part of the standard barrel segment is in the shape of a cylinder, and the lower part is in the shape of a tapered cylinder.

[0104] For tank bodies of different volumes, the standard barrel segments have the same shape but can have different sizes. For the same tank body, the standard barrel segments can have the same size or different sizes.

[0105] Whether it is a standard barrel segment or a non-standard barrel segment, the inside of the barrel segment is hollow and extends through both ends in the transverse direction to communicate with adjacent barrel segments to form a loading material passage. The end faces of the transverse ends of each barrel segment are in the shape of a circular ring, and the sizes of the end faces are the same, so that when the adjacent barrel segments are butted, they are welded through the annular gap to improve production efficiency.

[0106] The standard barrel segment and the standard barrel segment are connected by welding, and therefore, the standard barrel segment and the standard barrel segment have an annular welding line 13. The standard barrel segment and the non-standard barrel segment are also connected by welding and have an annular welding line 13.

[0107] The standard barrel segment in the present application can be independently manufactured and completed, and then a plurality of barrel segments 11 are arranged and combined according to the volume requirement and welded to obtain tank bodies 1 of different volumes.

[0108] In the present embodiment, the tank body 1 comprises five standard barrel segments, i.e., the front end barrel segment adopts a non-standard barrel segment, and the remaining barrel segments are standard barrel segments. Among them, the five barrel segments 11 have three height sizes, i.e., there are barrel segments 11 with the same height size.

[0109] The standard barrel segments are respectively a first barrel segment 111, a second barrel segment 112, a third barrel segment 113, a fourth barrel segment 114, and a rear end barrel segment 115 in the front-rear direction, i.e., in the view direction of Figure 1 from right to left are respectively the first barrel segment 111, the second barrel segment 112, the third barrel segment 113, the fourth barrel segment 114, and the rear end barrel segment 115. Among them, the first barrel segment 111 and the second barrel segment 112 have the same size, the height sizes of the second barrel segment 112, the third barrel segment 113, and the fourth barrel segment 114 are all different, and gradually decrease from front to back. The height size of the rear end barrel segment 115 is consistent with that of the fourth barrel segment 114. The height size refers to the vertical size.

[0110] Further, the axial dimensions of the standard cylinder segments can also be inconsistent. The axial dimension refers to the axial direction of the entire tank 1, i.e. the lateral direction. For example, the axial dimensions of the first cylinder segment 111, the second cylinder segment 112 and the third cylinder segment 113 are consistent, the axial dimensions of the third cylinder segment 113, the fourth cylinder segment 114 and the rear-end cylinder segment 115 have three dimensions, i.e. the axial dimensions of the three are inconsistent.

[0111] In this embodiment, the volume of the tank is 60m 3 .

[0114] In this embodiment, the number of standard cylinder segments is four. The four cylinder segments 21 have three height dimensions, i.e. the height dimensions of two of the cylinder segments 21 are the same.

[0128] The transition cylinder section comprises a cylinder body part in the shape of a cylinder and a transition part located at the lower part of the cylinder body part. When the transition cylinder section is connected with the adjacent cylinder section, the cylinder body part is connected with the first unit of the adjacent cylinder section, the transition part is inclined towards the adjacent cylinder section, and the transition part is connected with the second unit of the adjacent cylinder section.

[0129] The specific structure of the transition cylinder segment can refer to the description of the seventh embodiment of the cylinder segment.

[0130] The transition cylinder segment can be welded with the adjacent cylinder segment. When the transition cylinder segment is connected with the adjacent cylinder segment, the transition part is connected with the second unit of the cylinder segment, so that the material at the transition cylinder segment can slide along the inclined surface of the transition part to the adjacent cylinder segment, thereby achieving unloading.

[0131] In this embodiment, the bottom of the transition cylinder segment is not provided with an unloading hole.

[0132] In other embodiments, the bottom of the transition cylinder segment can also be provided with an unloading hole according to actual needs.

[0133] The transition cylinder segment is used to balance the volume of the entire tank 3, that is, the tank 3 can meet the various non-standard capacity requirements of customers through the provision of the transition cylinder segment. For example, when a plurality of standard cylinder segments can only realize the integer capacity requirement of the tank, the transition cylinder segment can provide a non-integer capacity requirement such as two or five, thereby meeting the individualized customization requirements of the tank capacity. At the same time, since the transition cylinder segment has a simple structure and does not need to be separately provided with an unloading hole, the structure of the cylinder segment is simplified under the premise that the tank 3 meets the capacity diversification requirement, thereby avoiding the phenomenon of increasing the weight and wasting the raw materials of the tank 3 due to the increase in the volume of the tank 3, reducing the weight of the tank 3, and saving the cost.

[0134] The transition cylinder segment for adjusting the capacity can be arranged between two adjacent standard cylinder segments, or between a non-standard cylinder segment at the front end of the tank and a standard cylinder segment, or between a non-standard cylinder segment at the tail end of the tank and a standard cylinder segment.

[0135] In this embodiment, the volume of the tank is 55m 3 .

[0136] The other technical features of the standard cylinder segment, the unloading hole 32, and the welding line 33 of the tank can refer to the first embodiment, which will not be described one by one.

[0145] In the present embodiment, the number of standard cylinder segments is three, which are the first cylinder segment 411, the second cylinder segment 412, and the rear-end cylinder segment 413 from front to back. Among them, the transition cylinder segment is located between the second cylinder segment 412 and the rear-end cylinder segment 413.

[0146] Among them, the height dimension of the first cylinder segment 411 is greater than the height dimension of the second cylinder segment 412, and the height dimension of the second cylinder segment 412 is consistent with the height dimension of the rear-end cylinder segment 413. That is, the three standard cylinder segments in the present embodiment have two height dimensions.

[0148] In the present embodiment, the volume of the tank body is 42m 3 .

[0149] The discharge hole 42 and the welding line 43 of the tank body 4, the front-end transition cylinder segment 441 and the rear-end transition cylinder segment 442, as well as other technical features, can be referred to the third embodiment, and will not be described again.

[0156] The axial dimensions of the four standard cylinder sections are set according to actual conditions.

[0157] The discharge hole and the welding line of the tank body, and other technical features can be described with reference to the first embodiment, and will not be described again.

[0158] The eighth embodiment of the tank body

[0159] The difference between the present embodiment and the first embodiment of the tank body is the number of cylinder sections. In the present embodiment, the number of cylinder sections is two.

[0160] Specifically, both of the cylinder sections are standard cylinder sections, and the two standard cylinder sections are connected along the axial direction to form a horizontal powder tank.

[0161] The tank body in the present application can select cylinder sections according to actual conditions. The number of standard cylinder sections, the height dimensions and the axial dimensions between the plurality of standard cylinder sections can be selected according to actual conditions. The number of transition cylinder sections and the specific structure of the transition cylinder section can be selected according to actual conditions. The cylinder section in the present application is described below through specific embodiments.

[0162] The first embodiment of the cylinder section

[0163] Referring to Figures 67~73 , the cylinder section includes a standard cylinder section 61 formed by welding two prefabricated half cylinder sections 611. The two half cylinder sections 611 are symmetrically distributed with respect to the vertical middle plane, and the two half cylinder sections 611 are respectively formed and then welded to obtain the standard cylinder section. The upper part of the standard cylinder section 61 is in a cylindrical shape, and the lower part is in a conical shape with an open bottom.

[0164] The half cylinder section 611 is integrally wound by a discharge plate 62. Referring to Figures 74~80Each half cylinder section 611 comprises a first unit 6115 and a second unit 6116 located at the bottom of the first unit 6115. The first unit 6115 is in the shape of a cylinder, and the second unit 6116 is in the shape of a half cone. The central axis of the first unit 6115 is perpendicular to the central axis of the second unit 6116, and the diameter of the second unit 6116 gradually decreases from top to bottom.

[0165] Specifically, the axis of the first unit 6115 extends in the lateral direction. The axis of the second unit 6116 extends in the vertical direction.

[0166] With reference to the view direction, the diameter of the left end is the diameter of the first unit 6115, and this end is defined as the small end. The diameter of the right end is the diameter of the structure composed of the first unit 6115 and the second unit 6116, and this end is defined as the large end. Figure 74

[0167] The second unit 6116 has an opening at the large end. Specifically, the opening is in the shape of a semicircle. The opening end is located at the bottom of the second unit 6116.

[0168] In this embodiment, when the two half cylinder sections 611 are connected to form a cylinder section 61, the height dimensions of the two half cylinder sections 611 are consistent. The two first units 6115 are connected to each other and still in the shape of a cylinder, and the two second units 6116 are connected to each other and form an inverted cone shape with the diameter gradually decreasing from top to bottom. That is, the large ends of the two half cylinder sections 611 are connected to each other. After the large ends are connected, the two openings enclose a hole in the shape of a circle, which is the discharge hole.

[0169] In this embodiment, the cross section of the lower part of the cylinder section 61 is in the shape of a circle, that is, the cross section of the shape enclosed by the second units 6116 of the two half cylinder sections 611 is in the shape of a circle. In other embodiments, the cross section of the lower part of the cylinder section 61 can also be in the shape of an ellipse or an oblong.

[0170] The half cylinder section 611 can be directly wound and integrally formed by a discharge plate 62.

[0171] Specifically, the discharge plate 62 is in an irregular shape and located in a plane, and is formed by winding.

[0172] With reference to Figure 81 ​The blanking plate 62 is a flat plate, comprising regular segments 621 and two irregular segments 622 integrally arranged at two ends of the regular segments 621 respectively. The regular segments 621 are rectangular, and the two irregular segments 622 are symmetrically distributed along a center axis L of the regular segments 621. The regular segments 621 comprise two first straight edges 6211 and a second straight edge 6212 which are parallel to each other and are arranged at intervals. The outer contour of the irregular segment 622 comprises a first edge 6221, a second edge 6222, a third edge 6223 and a fourth edge 6224 which are sequentially connected. The first edge 6221 is a straight edge and is integrally extended from the straight edge of the regular segment. The second edge 6222 is in a circular arc shape, the concave surface of the second edge 6222 faces outward of the blanking plate 62, the convex surfaces of the second edges 6222 of the two irregular segments 622 are oppositely arranged, the third edge 6223 is a straight edge, and the intersection point of the extension lines of the first edge 6221 and the third edge 6223 is the center of the circle where the second edge 6222 is located. The fourth edge 6224 is in an arc shape, and the convex surface thereof faces the first edge 6221. One end of the fourth edge 6224 is connected with the third edge 6223, and the other end thereof is connected with the second straight edge 6212 of the regular segment 621.

[0173] After the blanking plate 62 is wound into the half cylinder segment 61, the first straight edge 6211 and the second straight edge 6212 are shaped into two contour lines of the first unit 6115, and the two fourth edges 6224, the two third edges 6223 and the two second edges 6222 are shaped into the contour line of the second unit 6116.

[0174] Preferably, the central angle of the second edge 6222 is 90 degrees, that is, the second edge 6222 is in a quarter circle shape.

[0175] The embodiment also provides a forming method of a tank body which is welded by using the cylinder segment 61 of the utility model, and comprises the following steps:

[0176] The blanking plate 62 is cut out as a flat plate, including a regular section 621 and two irregular sections 622 integrally arranged at two ends of the regular section 621 respectively. The regular section 621 is in the shape of a rectangle, and the two first straight edges 6211 and the second straight edge 6212 are arranged at intervals. The outer contour of the irregular section 622 includes a first edge 6221, a second edge 6222, a third edge 6223 and a fourth edge 6224 connected in sequence. The first edge 6221 is a straight edge and is integrally extended from the straight edge of the regular section. The second edge 6222 is in the shape of a circular arc, the concave surface of the second edge 6222 faces outward of the blanking plate 62, the convex surfaces of the second edges 6222 of the two irregular sections 622 are oppositely arranged, the third edge 6223 is a straight edge, and the intersection of the extension lines of the first edge 6221 and the third edge 6223 is the center of the circle on which the second edge 6222 is located. The fourth edge 6224 is in the shape of an arc, and the convex surface thereof faces the first edge 6221. One end of the fourth edge 6224 is connected with the third edge 6223, and the other end is connected with the second straight edge 6212 of the regular section 621.

[0177] The blanking plate 62 is rolled into a half cylinder section 611 in a manner that the two irregular sections 622 are aligned and close to each other along the third edges 6223, so that the half cylinder section 611 includes a cylindrical first unit 6115 and a half-conical second unit 6116, and the central axis of the first unit 6115 is perpendicular to the central axis of the second unit 6116.

[0178] Specifically, when the blanking plate 62 is rolled into the half cylinder section 611, the half cylinder section 611 can be directly rolled into shape by a combined die. Alternatively, the first unit 6115 can be rolled into shape on one die, and then hoisted by a hoist to another die to roll the second unit 6116. Alternatively, the second unit 6116 can be rolled into shape on one die, and then hoisted by a hoist to another die to roll the first unit 6115.

[0179] The two half cylinder sections 611 of the same height are aligned along the axis and are spliced and welded to each other to form a cylinder section 61.

[0180] Specifically, the welding between the half cylinder sections 611 and the half cylinder sections 611 is a girth weld, which is beneficial to mechanized welding.

[0181] A plurality of cylinder sections 61 are spliced and welded to each other to form a tank body for loading materials.

[0182] Specifically, the welding between the cylinder sections 61 and the cylinder sections 61 is also a girth weld, which is beneficial to mechanized welding.

[0183] In the embodiment, the two preformed half cylinder segments are welded to form the cylinder segment, and then the cylinder segments are spliced along the axial direction of the cylinder to obtain the tank body. The welding between the two half cylinder segments is a girth weld, and the welding between the adjacent two cylinder segments is also a girth weld, which is beneficial to mechanized welding, thereby improving the production efficiency of the tank body.

[0184] Meanwhile, the forming method of the half cylinder segment and the forming method of the cylinder segment do not cause the effective space for loading materials in the tank body to be reduced due to the increased plate when the cylindrical structure and the conical structure are spliced and welded, thereby increasing the effective volume inside the tank body. Since the inside of the cylinder segment is smooth, the materials can flow smoothly to the bottom of the cylinder segment, and there is no dead angle for unloading, and the unloading is relatively clean.

[0185] In the embodiment, the two half cylinder segments 611 of the cylinder segment 61 are consistent in the axial direction.

[0186] In other embodiments, the two half cylinder segments 611 of the cylinder segment 61 can be inconsistent in the axial direction. For example, the rear-end cylinder segment in the first embodiment of the tank body, i.e. Figure 2 the cylinder segment at the left end in the middle, also includes two half cylinder segments, which are a left half cylinder segment and a right half cylinder segment, and the difference between the left half cylinder segment and the right half cylinder segment is that the axial dimensions are inconsistent.

[0187] Second embodiment of the cylinder segment

[0188] The difference between the embodiment and the first embodiment of the cylinder segment is that the forming method of the half cylinder segment is to press a transition surface at the junction of the first unit and the second unit before the winding forming of the blanking plate.

[0189] Specifically, a blanking plate located in a plane is pressed to form a transition surface, so that the blanking plate has multiple parts located in multiple planes, and then the winding forming is performed. The transition surface is in the form of a strip. After the blanking plate is wound into a half cylinder segment, the transition surface constitutes the intersection line between the first unit and the second unit. The intersection line refers to the intersection line formed on the surface when two three-dimensional structures intersect. In the embodiment, the two three-dimensional structures refer to the first unit and the second unit, and therefore the intersection line refers to the intersection line formed on the surface when the first unit and the second unit intersect.

[0190] Referring to Figure 82 , the structure of the blanking plate is basically the same as that of the blanking plate in the first embodiment of the cylinder segment, and the difference is that the blanking plate in the embodiment is first pressed to form a transition surface, which can be shown as a dashed line in the figure.

[0191] Generally, the blanking plate is a flat plate with uniform thickness. In order to improve the local strength of the drawing extension position of the blanking plate, a reinforcing plate is arranged inside the drawing extension position of the blanking plate during the winding of the half cylinder segment and the pressing of the transition surface.

[0192] Alternatively, the blanking plate can also be a plate with uneven thickness, and the thickness of the drawing extension position of the blanking plate is greater than that of other positions, thereby improving the local strength of the drawing extension position and enabling it to still meet the overall strength requirement after drawing extension. In specific implementation, the blanking plate can be formed by welding a plurality of plates with different thicknesses together, or can be integrally formed by special process, such as 3D printing process.

[0193] In the embodiment, in the forming method of the tank body, the following step is further included before rolling the blanking plate:

[0194] A transition surface is first pressed at the junction position of the first unit and the second unit.

[0195] When the transition surface is pressed, a reinforcing plate is further welded inside the drawing extension position of the blanking plate.

[0196] Then, the half cylinder section is formed by rolling, and the reinforcing plate is located inside the half cylinder section.

[0197] The remaining steps are the same as those in the first embodiment of the cylinder section.

[0198] The forming method in the embodiment further reduces the forming difficulty of the half cylinder section.

[0199] The other technical features of the cylinder section can be referred to the first embodiment of the cylinder section, and will not be described here.

[0200] Third embodiment of the cylinder section

[0201] Referring to Figure 83 The difference between the first embodiment of the cylinder section and the third embodiment is that the half cylinder section 711 is obtained by welding the upper part 7117 and the lower part 7118.

[0202] In the embodiment, the upper part 7117 constitutes the first unit, and the lower part 7118 constitutes the second unit. The half cylinder section 711 can be obtained by welding the upper part 7117 and the lower part 7118 in the up-down direction.

[0203] The upper part 7117 is arc-shaped, and has an opening at the bottom, and the lower part 7118 is located at the opening.

[0204] Specifically, the method for forming the cylinder section in the embodiment, i.e., the forming method of the tank body, includes the following steps:

[0205] A first blanking plate is cut out. The first blanking plate is a flat plate, and the first blanking plate is square.

[0206] Specifically, the first blanking plate is obtained by cutting according to the preset size.

[0207] The second blanking plate is a flat plate, and the first blanking plate is a fan ring.

[0208] Specifically, the second blanking plate is obtained by cutting according to a preset size.

[0209] The first blanking plate is rolled to form the upper part 7117, the second blanking plate is rolled to form the lower part 7118, and the upper part 7117 and the lower part 7118 are welded and connected in the up-down direction to obtain a half cylinder section, so that the half cylinder section includes a first unit in a cylindrical shape and a second unit in a half-conical shape, and the central axis of the first unit is perpendicular to the central axis of the second unit.

[0210] Two half cylinder sections with the same height size are butt-welded to each other in an aligned manner along the axis to form a cylinder section.

[0211] A plurality of cylinder sections are butt-welded to each other to form a tank body for loading materials.

[0212] In the embodiment, the half cylinder section is obtained by welding the upper part 7117 and the lower part 7118, and the two parts are face-to-face welded when welded, and the welding operation has a larger space and is convenient to operate.

[0213] Referring to Figure 84 , in other embodiments, one side of the upper part 7117 can be sealed, that is, the side is in a closed whole-circle structure, to increase the connection strength of the upper part 7117 and the lower part 7118.

[0214] Other technical features of the cylinder section can be referred to the first embodiment of the cylinder section, and will not be described here.

[0215] Fourth embodiment of the cylinder section

[0216] Referring to Figure 85 , the difference between the embodiment and the third embodiment of the tank body is that the structures of the upper part 8117 and the lower part 8118 of the cylinder section 81 are different.

[0217] Specifically, the lower part 8118 includes a half-conical part and arc-shaped parts arranged at two ends of the half-conical part, the two arc-shaped parts and the upper part 8117 form a first unit in a surrounding manner, and the half-conical part forms a second unit.

[0218] That is, compared with the third embodiment of the cylinder section, the central angle of the upper part 8117 in the embodiment is smaller.

[0219] The method of forming the tank body by using the cylinder section can be referred to the description in the third embodiment of the cylinder section, and will not be described here.

[0220] Referring to Figure 86 , in other embodiments, one side of the upper part 8117 can be sealed, that is, the side is in a closed whole-circle structure, to increase the connection strength of the upper part 8117 and the lower part 8118.

[0221] Other technical features of the cylindrical section can be referred to in the third embodiment of the cylindrical section, and will not be described in detail here.

[0222] Fifth embodiment of the cylinder section

[0223] The difference between this embodiment and the first embodiment of the tank is that the cylindrical section 91 also includes a reinforcing ring 912.

[0224] See Figures 87~93 The cylindrical section 91 includes a reinforcing ring 912. The reinforcing ring 912 can be located at any end of the cylindrical section 91, depending on the specific needs.

[0225] See Figure 94 and Figure 95 The reinforcing ring 912 is a closed annular ring, comprising a fitting portion 9121 and a transition portion 9122. The fitting portion 9121 fits against the inner wall of the cylindrical section 91, and the transition portion 9122 is located on the inner circumference of the fitting portion 9121 and extends radially along the fitting portion 9121. Specifically, the transition portion 9122 is located at the midpoint of the axial dimension of the fitting portion 9121.

[0226] The fitting part 9121 and the transition part 9122 can be integrally formed or welded together.

[0227] In other embodiments, the bonding portion 9121 may further include two bonding units arranged in parallel and spaced apart, and the two bonding units are connected by a transition portion 9122. That is, the two bonding units and the transition portion 9122 are welded together.

[0228] In another embodiment, the reinforcing ring may consist only of the fitting portion 9121.

[0229] See Figures 96~103 The cylindrical section 91 includes two reinforcing rings 912. At this time, reinforcing rings 912 are provided at both ends of the cylindrical section 91.

[0230] That is, the number of reinforcing rings 912 included in the cylindrical section 91 can be set according to actual needs.

[0231] The technical features of the cylindrical section 91, including the two halves of the cylindrical section 911, can be referred to the first embodiment of the cylindrical section, and will not be described in detail here.

[0232] Sixth embodiment of the cylinder section

[0233] The difference between this embodiment and the fifth embodiment of the cylindrical section is that the reinforcing ring is a non-closed arc shape with an opening at its bottom. Specifically, the concave surface of the reinforcing ring faces downwards.

[0234] The reinforcing ring is connected with the upper part of the cylinder segment, which not only increases the connecting strength between the two adjacent cylinder segments, but also makes the transition between the cylinder segments with different sizes smooth, avoids the material accumulation at the reinforcing part of the bottom due to the reinforcing ring at the bottom, and ensures the clean unloading.

[0235] The other technical features of the cylinder segment can refer to the fifth embodiment of the cylinder segment, which will not be described here.

[0236] Seventh embodiment of the cylinder segment

[0237] The cylinder segment in this embodiment refers to the transition cylinder segment, Figure 104 and Figure 105 respectively show the structure schematic diagram of the transition cylinder segment 64 with different angles, Figures 106-111 show the six surface diagram of the transition cylinder segment 64, combined Figures 82-89 , the transition cylinder segment 64 includes the cylinder part 641 with a cylindrical contour and the transition part 642 located at the lower part of the cylinder part 641, the cylinder part 641 is connected with the first unit of the adjacent cylinder segment, the transition part 642 is inclined towards the adjacent cylinder segment, and the transition part 642 is connected with the second unit of the adjacent cylinder segment.

[0238] The cylinder part 641 is an arc shape with an opening at the bottom. Specifically, the concave surface of the cylinder part 641 faces downward, and the central angle of the cylinder part 641 is greater than 180 degrees. And the cylinder part 641 is matched with the adjacent cylinder segment.

[0239] The cylinder part 641 can be integrally formed by winding a plate material.

[0240] The transition part 642 is arranged at the opening to block the opening of the cylinder part 641, so that the transition cylinder segment 64 is closed.

[0241] Specifically, the transition part 642 is a sector shape, and the concave surface thereof faces the cylinder part, i.e. upward.

[0242] The transition part 642 is arranged to be inclined downward along the direction close to the adjacent cylinder segment.

[0243] The transition part 642 can be integrally formed by winding a plate material.

[0244] The transition cylinder segment 64 can be obtained by welding the cylinder part 641 and the transition part 642.

[0245] Further, the cylinder part 641 extends downward to form two ear plates that shield the transition part 642, and the bottom of the transition part 642 extends downward beyond the bottom of the cylinder part 641.

[0246] The transition cylinder segment 64 is arranged between two adjacent cylinder segments, and the material slides to the adjacent cylinder segment for unloading through the inclination of the transition portion 642, so that the tank body meets the volume requirement, avoids increasing the volume of the tank body to increase the weight and waste the raw materials of the tank body, reduces the weight of the tank body, and saves the cost.

[0247] Referring to Figure 112 The two transition cylinder segments 64 can also be welded to form a whole relative to the vertical middle surface. After the two transition cylinder segments 64 are connected, the top of the two transition portions 642 is connected, and the cross section of the two transition portions 642 is inverted V-shaped, that is, each transition portion 642 is inclined towards the adjacent cylinder segment.

[0248] And the two transition cylinder segments 64 are symmetrically distributed about the vertical middle surface.

[0249] Eighth embodiment of the cylinder segment

[0250] Figure 113 The structure of the transition cylinder segment 74 is shown, Figure 114 The cross-sectional view of the transition cylinder segment 74 is shown, Figures 115-120 The six surface view of the transition cylinder segment 74 is shown, referring to Figures 113-120 The difference between the transition cylinder segment 74 and the seventh embodiment of the cylinder segment in this embodiment is that the cylinder portion 741 is a closed ring, and the transition portion 742 is inverted V-shaped.

[0251] Specifically, the cylinder portion 741 is a closed whole structure. The cylinder portion 741 can be integrally formed by winding a plate.

[0252] The transition portion is located inside the cylinder portion 741 and connected with the inner wall of the cylinder portion 741.

[0253] Specifically, the transition portion is inverted V-shaped, including two inclined surfaces arranged at an acute angle with each other, and the joint of the two inclined surfaces is arched to form a sharp corner relative to the inner wall of the cylinder portion 741. The edges of the two inclined surfaces are connected with the inner surface of the cylinder portion 741 and cover part of the area of the cylinder portion 741. The part of the area of the cylinder portion 741 covered by the transition portion is provided with a weight-reducing hole 743 to reduce the weight of the transition cylinder segment 74, and thus reduce the weight of the whole tank body.

[0254] The two inclined surfaces of the transition portion and the cylinder portion 741 form a cavity for loading the powder particles. The two inclined surfaces provide unloading guidance for the powder particles to slide along the two inclined surfaces into the adjacent cylinder segment of the transition cylinder segment 74, realizing the loading and unloading of the material.

[0255] In this embodiment, the inclined surface is a straight plate. In other embodiments, the inclined surface can also be an arc-shaped plate with an inclination angle.

[0256] The two inclined surfaces can be integrally formed by bending a plate, or can be respectively formed and then welded into a structure with an included angle.

[0257] When the whole formed by the transition cylinder segment 74 is connected with adjacent cylinder segments, the cylinder part 741 forms a closed annular structure, which is beneficial to improve the overall strength of the tank body, and since the adjacent cylinder segments can be connected by girth welding, automatic production is facilitated.

[0258] In other embodiments, the transition part can also be formed by an inclined surface that is inclined from one side to the other side of the cylinder part 741. In actual application, the lower end of the inclined surface can face the adjacent cylinder segment on the front side or the adjacent cylinder segment on the rear side.

[0259] Other technical features of the cylinder segment can be referred to the seventh embodiment of the cylinder segment, and will not be described here.

[0260] Ninth embodiment of the cylinder segment

[0261] Figure 121 The structure of the cylinder segment group is shown, Figures 122-127 The six views of the cylinder segment group are shown, Figures 121-127 In this embodiment, the cylinder segment group is formed by two transition cylinder segments 84.

[0262] Each transition cylinder segment 84 includes a cylinder part 841 with a cylindrical contour and a transition part 842 located at the lower part of the cylinder part 841. The cylinder part 841 is connected with the first unit of the adjacent cylinder segment, the bottom surface of the transition part 842 is inclined towards the adjacent cylinder segment, and the transition part 842 is connected with the second unit of the adjacent cylinder segment.

[0263] In the cylinder segment group, the two transition cylinder segments 84 are arranged and connected along the axial direction of the cylinder part 841. The cylinder parts 841 of the two transition cylinder segments 84 have the same diameter, the transition parts 842 of the two transition cylinder segments 84 form inclined surfaces inclined relative to the axial direction, and the junction of the two inclined surfaces forms a ridge protruding from the internal space of the cylinder segment group, so that the two transition cylinder segments 84 are both outwardly trumpet-shaped from the junction.

[0264] In this embodiment, the transition cylinder segment 84 can be obtained by welding an upper part and a lower part. The upper part is cylindrical. Alternatively, the upper part is substantially cylindrical, i.e., the two end parts have inclined downward arc-shaped structures. The lower part is an arc-shaped plate with an inclined angle. Alternatively, the lower part can also be a straight plate.

[0265] From the above technical solutions, the advantages and positive effects of the present application are as follows:

[0266] The whole structure of the tank body is grouped according to different specifications, forming standard universal cylinder segments with cylindrical cone of different square amounts, then the cylinder segments of different square amounts are arranged and combined horizontally to form the tank body of different square amounts, and finally the cylinder segments are welded to form the whole tank body.

[0267] In the process of forming the cylinder segment, the cylinder segment is divided into two parts according to the axis of symmetry of the cone, and the two parts are formed into two half cylinder segments, and then the two half cylinder segments are butt-welded to form a cylinder segment, which greatly simplifies the forming difficulty of the single cylinder segment, enables the half cylinder segment to be integrally formed, simplifies the forming process of the tank body, optimizes the cross section of the two ends of the single cylinder segment, and makes the two ends of the single cylinder segment have the same size. Therefore, when welding adjacent cylinder segments, only the adjacent cylinder segments need to be welded by ring seam welding, which improves the standard universality of the production process, facilitates mechanized automatic welding, and improves the production efficiency of the tank body. Secondly, by horizontally combining different cylinder segments and uniformly using longitudinal ring seam welding, the product welding quality is effectively improved, thereby improving the overall quality of the product. Thirdly, by arranging and combining the square amounts of various standard universal cylinder segments, the product series standardization structure is effectively improved, and the product design and management efficiency is improved. Finally, by using ring seam welding of various standard universal cylinder segments, various defects such as non-standard, non-standard, uneven joints, high welding labor intensity, high splicing riveting difficulty, poor product welding quality, etc. caused by traditional cylinder and cone splicing welding can be effectively avoided.

[0268] Although the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. As the application can be embodied in many different forms without departing from the spirit or essential characteristics thereof, it is understood that the present embodiments are not limited to any particular details of the foregoing description, but are broadly interpreted in accordance with the principles of the application. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be embraced by the claims.
