Description

[0001] This application is a divisional application of the invention entitled "Tank Truck, Tank Body, Cylindrical Section, Semi-Cylindrical Section and Method for Molding Tank Body", with the original application date being July 1, 2022, and the original application number being 2022107653785. Technical Field

[0002] This invention relates to the field of special vehicle technology, and in particular to a tank truck, tank body, cylindrical section, semi-cylindrical section, and a method for forming the tank body. Background Technology

[0003] Currently, powdery materials are typically transported in tanks. Tanks are generally classified into vertical and horizontal tanks based on their unloading method. Both horizontal and vertical tanks consist of an upper cylindrical body and a unloading structure at the bottom of the cylindrical body. The unloading structure of a horizontal tank is usually V-shaped or W-shaped. The inclined surface formed by the V-shaped or W-shaped unloading structure guides the material to the unloading port at the bottom for unloading. However, the inclination angle of the V-shaped or W-shaped unloading structure is limited. While it can achieve unloading for powdery materials with good fluidization properties, it is difficult to unload materials with poor fluidization properties. To adapt to materials with different fluidization properties, improve unloading speed, and reduce unloading residue, vertical tanks were developed. Vertical tanks typically consist of a cylindrical body and multiple (usually four or more) cylindrical cones arranged sequentially along the axial direction at the bottom of the cylindrical body. The bottom of each cone forms an open opening, which serves as the discharge port, allowing the vertical tank to form multiple separate discharge compartments. Each compartment utilizes the large inclination angle of the outer circumference of the cylindrical cone to achieve rapid discharge, solving the problem of discharging materials with poor fluidization properties.

[0004] However, in the traditional production process of vertical tanks, a cylindrical body is first prepared, then multiple openings are made at the bottom of the body. Several pre-prepared cylindrical cones are then inserted into these openings, with their larger ends corresponding to the cones. The cones are then welded to the cylindrical body to form the tank. However, during the welding of the cones to the cylindrical body, the weld seam is located inside the cylindrical body, requiring operators to enter the body for operation. This is inconvenient, leading to low welding efficiency and consequently low overall tank production efficiency. Furthermore, additional connecting structures are needed to connect the cones and the cylindrical body. These connecting structures are usually located inside the tank, which not only reduces the effective internal volume of the tank but also obstructs the flow of material from the tank to the bottom of the cones, creating dead zones for unloading and resulting in incomplete unloading. Summary of the Invention

[0005] The purpose of this invention is to provide a semi-cylindrical section, a cylindrical section, a tank body, a tank truck, and a method for forming the tank body, so as to solve the problems of low tank body production efficiency, low effective volume inside the tank, and incomplete unloading in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides a semi-cylindrical section of a tank body, wherein the semi-cylindrical section is obtained by welding the upper part and the lower part in the vertical direction; the semi-cylindrical section includes a first unit and a second unit located at the bottom of the first unit, the first unit is cylindrical, the second unit is semi-conical, the central axis of the first unit is perpendicular to the central axis of the second unit, and the diameter of the second unit gradually decreases from top to bottom, the lower part includes a semi-conical part and arc-shaped parts arranged at both ends of the semi-conical part.

[0007] In one embodiment, the upper part constitutes the first unit, and the lower part constitutes the second unit.

[0008] In one embodiment, the two arc-shaped portions and the upper portion together form the first unit, and the semi-conical portion forms the second unit.

[0009] The present invention also provides a cylindrical section of a tank, comprising a standard cylindrical section formed by welding two prefabricated semi-cylindrical sections together. The semi-cylindrical sections are as described above. The upper part of the standard cylindrical section is cylindrical, and the lower part is conical with an opening at the bottom. The standard cylindrical section is hollow inside and extends through both ends in the transverse direction. The end faces of both ends of the cylindrical section in the transverse direction are annular.

[0010] In one embodiment, the lower cross-section of the standard cylindrical section is circular, elliptical, or oblong.

[0011] In one embodiment, the cylindrical section further includes a reinforcing ring disposed at at least one end of the standard cylindrical section;

[0012] The reinforcing ring is a closed annular ring.

[0013] In one embodiment, the cylindrical section further includes a reinforcing ring disposed at at least one end of the standard cylindrical section;

[0014] The reinforcing ring is an open arc shape with an opening at its bottom.

[0015] In one embodiment, the two semi-cylindrical sections have the same dimensions along the height direction.

[0016] In one embodiment, the dimensions of the two semi-cylindrical sections along the axial direction of the first unit are inconsistent.

[0017] In one embodiment, the two semi-cylindrical sections have the same dimension along the axial direction of the first unit.

[0018] The present invention also provides a tank comprising at least two cylindrical sections as described above, each of the cylindrical sections being spliced ​​together along the axial direction of its own cylindrical first unit.

[0019] In one embodiment, the tank further includes a transition section, which includes a cylindrical body portion with a cylindrical profile and a transition portion located at the lower part of the cylindrical body portion. The cylindrical body portion is connected to a first unit of the adjacent cylindrical section, the bottom surface of the transition portion is inclined toward the adjacent cylindrical section, and the transition portion is connected to a second unit of the adjacent cylindrical section.

[0020] In one embodiment, the cylindrical portion is a closed annular ring, and the transition portion is located inside the cylindrical portion and connected to the inner wall of the cylindrical portion; the transition portion includes two inclined surfaces arranged at an acute angle to each other, and the joint of the two inclined surfaces arches relative to the inner wall of the cylindrical portion to form a sharp angle; or, the transition portion includes an inclined surface that slopes from one side of the cylindrical portion to the other axially.

[0021] In one embodiment, the cylindrical part is an open arc shape with an opening at the bottom. The transition part is disposed at the opening. The cylindrical part extends downward to form two ear plates that cover the transition part. The bottom of the transition part extends downward beyond the bottom of the cylindrical part.

[0022] In one embodiment, the tank body further includes a cylinder group consisting of two transition cylinder sections. The two transition cylinder sections are arranged and connected along the axial direction of the cylinder body. The cylinder body diameters of the two transition cylinder sections are the same. The transition portion of the two transition cylinder sections is an inclined surface that is inclined relative to the axial direction. The joint portion of the two inclined surfaces forms a ridge that protrudes from the internal space of the cylinder group, so that the two transition cylinder sections gradually expand outward from their joint portion into a trumpet shape.

[0023] In one embodiment, at least two of the cylindrical sections have different dimensions along the height direction;

[0024] At least two of the cylindrical sections have inconsistent dimensions along the axial direction of the first unit.

[0025] The present invention also provides a method for forming a tank, comprising the following steps:

[0026] Cut out the first blanking plate, which is flat and square;

[0027] Cut out a second blanking plate, which is a flat plate, while the first blanking plate is fan-shaped;

[0028] The first blanking plate is rolled into shape to obtain the upper part, and the second blanking plate is rolled into shape to obtain the lower part. The upper part and the lower part are welded together in the vertical direction to obtain a semi-cylindrical section, such that the semi-cylindrical section includes a cylindrical first unit and a semi-conical second unit, and the central axis of the first unit is perpendicular to the central axis of the second unit; the lower part includes a semi-conical part and arc-shaped parts arranged at both ends of the semi-conical part.

[0029] Two semi-cylindrical sections of the same height are welded together along the axis to form a single cylindrical section.

[0030] Multiple cylindrical sections are assembled and welded together to form a tank for loading materials.

[0031] In one embodiment, the upper part constitutes the first unit, and the lower part constitutes the second unit.

[0032] In one embodiment, the two arc-shaped portions and the upper portion together form the first unit.

[0033] The present invention also provides a tanker truck, including a frame and a tank disposed on the frame, wherein the tank adopts the tank type described above.

[0034] As can be seen from the above technical solution, the advantages and positive effects of the present invention are as follows:

[0035] This invention involves grouping the overall tank structure into sections with different volumes and specifications, forming standard, universally applicable cylindrical sections with conical shapes. These sections are then arranged laterally to create tanks of varying volumes. Finally, the sections are welded together to form the complete tank. The innovative method of section forming involves dividing the section into two parts along the axis of symmetry of the cone, creating two semi-cylindrical sections. These semi-cylindrical sections are then butt-welded together to form a single section. This significantly simplifies the forming of individual sections and optimizes the cross-sections at both ends, ensuring that both ends of each section are identical annular rings. Therefore, adjacent sections can be welded using a circumferential weld, improving the standardization and versatility of the production process, facilitating mechanized and automated welding, and increasing tank production efficiency. Secondly, by combining different cylindrical sections laterally and uniformly adopting a longitudinal circumferential weld method, the welding quality of the product is effectively improved, thereby improving the overall quality of the product. Thirdly, by using standard and universally applicable cylindrical sections of various specifications for circumferential welds, the structural form of product serialization and standardization is effectively improved, and the efficiency of product design and management is enhanced. Finally, using standard and universally applicable cylindrical sections of various specifications for circumferential welds can effectively avoid various defects caused by traditional cylindrical and conical splicing and welding, such as non-standardization, uneven joints, high welding labor intensity, high splicing and riveting difficulty, and poor product welding quality.

[0036] Furthermore, this invention optimizes the molding process by rolling each half-cylinder section into a single piece using a blanking plate, which greatly improves production efficiency, facilitates large-scale mechanized production, reduces labor intensity and safety hazards for workers, and also lowers labor costs.

[0037] The forming methods of both the semi-cylindrical sections and the cylindrical sections eliminate the problem of reduced effective space for loading materials inside the tank due to the additional plate material added during the splicing and welding of the cylindrical and conical structures. This effectively improves the tank's volume utilization rate and reduces the overall weight of the tank. Because the interior of the cylindrical sections is smooth, materials can flow smoothly to the bottom of the cone of each section, eliminating dead zones for unloading and ensuring clean and quick unloading.

[0107] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0108] To further illustrate the principles and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0109] This invention provides a tanker truck for transporting powdery materials, such as chemical powders and food powders.

[0110] A tanker truck consists of a chassis and a tank mounted on the chassis.

[0111] The tank structure of the present invention is particularly suitable for vertical tanks.

[0112] For ease of description, the length direction of the frame is defined as longitudinal, the width direction of the frame as transverse, the direction closer to the front of the vehicle is the front, and the direction farther from the front of the vehicle is the rear.

[0113] The tank consists of at least two cylindrical sections.

[0114] This invention involves grouping the overall tank structure into different specifications according to different volumes to form standard, universally applicable cylindrical sections with cylindrical cones of different volumes. Then, the cylindrical sections of different volumes are arranged and combined laterally to form tanks of different volumes. Finally, the cylindrical sections of the combined tanks are circumferentially welded to form an integral tank.

[0115] The tank of this invention is not only easy to form and has high production efficiency, but also has a large effective loading rate. The tank is described below through specific embodiments.

[0116] Tank First Embodiment

[0117] Figure 1 A schematic diagram of the structure of tank 1 in this embodiment is shown. Figure 2 The front view of tank 1 in this embodiment is shown. Figure 3 The bottom view of tank 1 in this embodiment is shown. Figure 4-11 This diagram shows the effect of tank 1 in this embodiment, combined with... Figures 1-11 The tank body 1 comprises multiple cylindrical sections 11. The multiple cylindrical sections 11 are arranged laterally and connected end to end to form the tank body 1. Each cylindrical section 11 has a discharge port 12 at its bottom for unloading materials.

[0118] Of the multiple cylindrical sections 11, the one located at the end is the end cylindrical section. Among them, in order to meet the volume requirements of the tank body 1 and the fit requirements between the tank body 1 and the vehicle frame, the end cylindrical section can be a non-standard cylindrical section, while the other cylindrical sections can be the standard cylindrical section 11 of this application.

[0119] The upper part of the standard cylindrical section 11 is cylindrical, and the lower part is conical.

[0120] For tanks of different volumes, the standard cylindrical section 11 has the same shape, but the dimensions may be different. For the same tank, the dimensions of the standard cylindrical section 11 may be the same or different.

[0121] Whether standard or non-standard, each cylindrical section is hollow inside and extends laterally through both ends to connect with adjacent sections and form a cargo hold. The end faces of each section are annular with identical dimensions, allowing for circumferential welding between adjacent sections, thus improving production efficiency.

[0122] Standard cylindrical sections 11 are connected to each other by welding, thus forming a ring-shaped weld line 13 between them. Standard cylindrical sections 11 are also connected to non-standard cylindrical sections by welding, also forming a ring-shaped weld line 13.

[0123] The standard cylindrical section 11 in this application can be manufactured independently, and then multiple cylindrical sections 11 can be arranged and welded together according to the volume requirements to obtain tanks 1 with different volumes.

[0124] In this embodiment, the tank body 1 includes five standard cylindrical sections 11, that is, the front cylindrical section is a non-standard cylindrical section, and the rest are standard cylindrical sections 11. Among them, the five cylindrical sections 11 have three height dimensions, that is, there are cylindrical sections 11 with the same height dimension.

[0125] The standard cylindrical section 11 consists of the first cylindrical section 111, the second cylindrical section 112, the third cylindrical section 113, the fourth cylindrical section 114, and the rear cylindrical section 115 along the front-rear direction, i.e. Figure 1 With the view direction as a reference, from right to left, the sections are: first section 111, second section 112, third section 113, fourth section 114, and rear section 115. The first section 111 and second section 112 have the same dimensions. The height dimensions of the second section 112, third section 113, and fourth section 114 are different, gradually decreasing from front to back. The rear section 115 and fourth section 114 have the same height dimension. Height dimension refers to the vertical dimension.

[0126] Furthermore, the axial dimensions of standard cylindrical sections 11 may also be inconsistent. Here, the axial dimension refers to the axial direction of the entire tank body 1, that is, the transverse direction. For example, the first cylindrical section 111, the second cylindrical section 112, and the third cylindrical section 113 have the same axial dimensions, while the third cylindrical section 113, the fourth cylindrical section 114, and the rear cylindrical section 115 have three different axial dimensions, meaning their axial dimensions are all inconsistent.

[0127] In this embodiment, the tank volume is 60m³. 3 .

[0128] Second embodiment of the tank

[0129] Figure 12 A schematic diagram of the structure of tank 2 in this embodiment is shown. Figure 13 The front view of tank 2 in this embodiment is shown. Figure 14 The bottom view of tank 2 in this embodiment is shown. Figures 15-22 This diagram shows the effect of tank 2 in this embodiment, combined with... Figures 12-22 The difference between the tank body 2 in this embodiment and the first embodiment is in the number of standard cylindrical sections 21 and the size difference between the standard cylindrical sections 21.

[0130] In this embodiment, there are four standard cylindrical sections 21. The four cylindrical sections 21 have dimensions in three height directions, that is, two of the cylindrical sections 21 have the same height dimension.

[0131] The cylindrical sections 21 from front to back are the first cylindrical section 211, the second cylindrical section 212, the third cylindrical section 213, and the rear cylindrical section 214, that is, with Figure 13 With the view direction as a reference, from right to left are the first cylinder section 211, the second cylinder section 212, the third cylinder section 213 and the rear cylinder section 214. The height dimensions of the first cylinder section 211, the second cylinder section 212 and the third cylinder section 213 are different and gradually decrease from right to left. The height dimensions of the third cylinder section 213 and the rear cylinder section 214 are the same.

[0132] The first cylinder section 211 and the second cylinder section 212 have the same axial dimensions, and the axial dimension of the first cylinder section 211 is larger than the axial dimension of the rear cylinder section 214, and the axial dimension of the rear cylinder section 214 is larger than the axial dimension of the third cylinder section 213.

[0133] In this embodiment, the tank volume is 50m³. 3 .

[0134] Other technical features such as the unloading hole 22 and welding line 23 of the tank body can be referred to in the first embodiment, and will not be described in detail here.

[0135] Third embodiment of the tank

[0136] Figure 23 A schematic diagram of the structure of tank 3 in this embodiment is shown. Figure 24 The front view of tank 3 in this embodiment is shown. Figure 25 The bottom view of tank 3 in this embodiment is shown. Figures 26-33 This diagram shows the effect of tank 3 in this embodiment, combined with... Figures 23-33 The difference between the tank body 3 in this embodiment and the first embodiment is that the number of standard cylindrical sections and the size difference between the standard cylindrical sections 31 are different, and the tank body also includes a transition cylindrical section 34.

[0137] In this embodiment, there are four standard cylindrical sections 31. The four cylindrical sections 31 have two height dimensions.

[0138] The cylindrical sections 31 from front to back are the first cylindrical section 311, the second cylindrical section 312, the third cylindrical section 313, and the rear cylindrical section 314, that is, with Figure 23 With the view direction as a reference, from right to left are the first cylinder section 311, the second cylinder section 312, the third cylinder section 313, and the rear cylinder section 314. The first cylinder section 311 and the second cylinder section 312 have the same height dimension, the third cylinder section 313 and the rear cylinder section 314 have the same height dimension, and the height dimension of the second cylinder section 312 is greater than the height dimension of the third cylinder section 313.

[0139] The first cylinder section 311 and the second cylinder section 312 have the same axial dimensions, and the axial dimension of the first cylinder section 311 is larger than the axial dimension of the rear cylinder section 314, and the axial dimension of the rear cylinder section 314 is larger than the axial dimension of the third cylinder section 313.

[0140] The tank body 3 also includes a transition section. The bottom of the transition section is an inclined surface that slopes toward the adjacent section 31, and the upper profile is cylindrical.

[0141] Specifically, in this embodiment, there are three transition sections 34, namely a front transition section 341 located at the front end and two rear transition sections 342 located at the rear end.

[0142] The front transition section 341 is located between the front end section and the first section 311. The bottom of the front transition section 341 slopes downward from front to back.

[0143] The two rear transition sections 342 are adjacent and symmetrically distributed with respect to their vertical midline. The two rear transition sections 342 are located between the rear section 314 and the third section 313.

[0144] The transition section includes a cylindrical body with a cylindrical profile and a transition section located at the lower part of the cylindrical body. When the transition section is connected to an adjacent section 31, the cylindrical body is connected to the first unit of the adjacent section 31, the transition section is inclined toward the adjacent section 31, and the transition section is connected to the second unit of the adjacent section.

[0145] The specific structure of the transition section can be referred to the description of the seventh embodiment of the section.

[0146] The transition section 34 can be welded to the adjacent section 31. When the transition section 34 is connected to the adjacent section 31, the transition part is connected to the second unit of the section 31, so that the material at the transition section 34 can slide down the inclined surface of the transition part to the adjacent section 31, thereby realizing unloading.

[0147] In this embodiment, no discharge hole is provided at the bottom of the transition section 34.

[0148] In other embodiments, the bottom of the transition section 34 may also be provided with a discharge hole as needed.

[0149] The transition section 34 is used to balance the volume of the entire tank 3. That is, by setting up the transition section 34, the tank 3 can meet various non-standard capacity requirements of customers. For example, when multiple standard section combinations can only achieve the integer capacity requirement of the tank, the transition section 34 can provide non-integer capacity requirements such as two cubic meters or five cubic meters, thus meeting the personalized customization needs of the tank capacity. At the same time, because the transition section 34 has a simple structure and does not require a separate discharge port, it simplifies the section structure while meeting the diverse capacity requirements of the tank 3. This avoids increasing the volume and weight of the tank 3 and wasting raw materials, thus reducing the weight of the tank 3 and saving costs.

[0150] Transition cylinders used for adjusting volume can be set between two adjacent standard cylinders, between a non-standard cylinder and a standard cylinder at the front end of the tank, or between a non-standard cylinder and a standard cylinder at the rear end of the tank.

[0151] In this embodiment, the tank volume is 55m³. 3 .

[0152] Other technical features such as the standard cylindrical section 31 of the tank body, the discharge hole 32, and the welding line 33 can all be referred to in the first embodiment, and will not be described in detail here.

Figure 36 The bottom view of tank 4a in this embodiment is shown. Figures 37-44 This diagram shows the effect of tank 4 in this embodiment, combined with... Figures 34-44 The difference between the tank 3a in this embodiment and the third embodiment lies in the specific structure of the rear transition cylinder 342a.

[0155] In this embodiment, the outer contour of the rear transition section 342a is cylindrical, which is different from the upper round and lower sloping structure of the third embodiment described above.

[0156] The specific structure of the rear transition section 342a in this embodiment is described in the eighth embodiment of the section.

[0157] In this embodiment, the tank volume is 55m³. 3 .

[0159] Fifth embodiment of the tank

[0160] Figure 45 A schematic diagram of the structure of tank 4 in this embodiment is shown. Figure 46 The front view of tank 4 in this embodiment is shown. Figure 47 The bottom view of tank 4 in this embodiment is shown. Figures 48-55 This diagram shows the effect of tank 4 in this embodiment, combined with... Figures 45-55 The difference between the tank 4 in this embodiment and the third embodiment is that the number of standard cylindrical sections 41 and the size differences between the standard cylindrical sections 41 are as follows.

[0161] In this embodiment, there are three standard cylindrical sections 41, which are, from front to back, the first cylindrical section 411, the second cylindrical section 412, and the rear cylindrical section 413. The transition cylindrical section 44 is located between the second cylindrical section 412 and the rear cylindrical section 413.

[0162] In this embodiment, the height of the first cylindrical section 411 is greater than that of the second cylindrical section 412, and the height of the second cylindrical section 412 is the same as that of the rear cylindrical section 413. That is, the three standard cylindrical sections 41 in this embodiment have two height dimensions.

[0163] The axial dimension of the first cylinder section 411 is greater than the axial dimension of the rear cylinder section 413, and the axial dimension of the rear cylinder section 413 is greater than the axial dimension of the second cylinder section 412. That is, the three standard cylinder sections 41 have three axial dimensions.

[0164] In this embodiment, the volume of the tank is 42m³. 3 .

[0165] Other technical features of the tank body 4, such as the unloading hole 42 and welding line 43, the front transition cylinder 441 and the rear transition cylinder 442, can be referred to the third embodiment, and will not be described in detail here.

[0166] Sixth embodiment of the tank

[0167] The difference between the tank in this embodiment and the fifth embodiment lies in the specific structure of the rear transition cylinder 442. The specific structure of the rear transition cylinder 442 is described in the eighth embodiment of the cylinder. In this embodiment, the tank volume is 42m³. 3 .

[0168] Other technical features of the tank body, such as the first cylindrical section 411a, the second cylindrical section 412a, the rear cylindrical section 413a, the front transition cylindrical section 441a, the discharge hole 42a, and the welding line 43a, are all described in the fifth embodiment and will not be repeated here.

[0169] Seventh embodiment of the tank

[0170] The difference between the tank in this embodiment and the first embodiment is the number of standard cylindrical sections.

[0171] In this embodiment, there are four standard cylindrical sections, and the height dimensions of the four standard cylindrical sections are all the same.

[0172] The axial dimensions of the four standard cylinder sections are set according to the actual situation.

[0173] Other technical features of the tank body, such as the unloading hole and welding line, can be referred to in the first embodiment, and will not be described in detail here.

[0174] Eighth embodiment of the tank

[0175] The difference between this embodiment and the first embodiment of the tank is the number of cylindrical sections; in this embodiment, there are two cylindrical sections.

[0176] Specifically, both cylindrical sections are standard cylindrical sections, and the two standard cylindrical sections are connected axially to form a horizontal powder silo.

[0177] The tank body in this application can be selected according to actual conditions, including the number of standard sections, the height between multiple standard sections, and the axial dimensions. Similarly, the number of transition sections and their specific structure can also be selected based on actual conditions. The following specific embodiments illustrate the tank sections used in this application.

[0178] First embodiment of the cylinder section

[0179] See Figures 67-73 The cylindrical section comprises a standard cylindrical section 61 formed by welding two prefabricated semi-cylindrical sections 611 together. The two semi-cylindrical sections 611 are symmetrically distributed with respect to their vertical mid-plane, and the standard cylindrical section 611 is obtained by welding the two semi-cylindrical sections 611 together after each is formed. The upper part of the standard cylindrical section 61 is cylindrical, and the lower part is conical with an opening at the bottom.

[0180] The semi-cylindrical section 611 is integrally wound and formed by a lower material plate 62. (See reference...) Figures 74-80 Each semi-cylindrical section 611 includes a first unit 6115 and a second unit 6116 located at the bottom of the first unit 6115. The first unit 6115 is cylindrical, and the second unit 6116 is semi-conical. 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.

[0181] Specifically, the axis of the first unit 6115 extends laterally. The axis of the second unit 6116 extends vertically.

[0182] by Figure 74With the view direction as a reference, the diameter of its left end is the diameter of the first unit 6115, and this end is defined as the small-mouth end. The diameter of its right end is the diameter of the structure jointly formed by the first unit 6115 and the second unit 6116, and this end is defined as the large-mouth end.

[0183] The second unit 6116 has an opening at its larger end. Specifically, the opening is semi-circular. This opening is located at the bottom of the second unit 6116.

[0184] In this embodiment, when two semi-cylindrical sections 611 are connected to form a single cylindrical section 61, the height dimensions of the two semi-cylindrical sections 611 are identical. The two first units 6115 are connected to each other and remain cylindrical, while the two second units 6116 are connected to each other to form an inverted cone shape with a gradually decreasing diameter from top to bottom. That is, the larger openings of each semi-cylindrical section 611 are connected to each other. After the larger openings are connected, the two openings enclose a circular hole, i.e., a discharge hole.

[0185] In this embodiment, the lower cross-section of the cylindrical section 61 is circular, that is, the cross-section of the shape enclosed by the second unit 6116 of the two semi-cylindrical sections 611 is circular. In other embodiments, the lower cross-section of the cylindrical section 61 may also be oblong or elliptical.

[0186] Among them, the semi-cylindrical section 611 can be directly wound into one piece by a material plate 62.

[0187] Specifically, the blanking plate 62 is irregularly shaped and located in a plane, and is formed by rolling.

[0188] See Figure 81 The blanking plate 62 is a flat plate, comprising a regular segment 621 and two irregular segments 622 integrally disposed at both ends of the regular segment 621. The regular segment 621 is rectangular, and the two irregular segments 622 are symmetrically distributed along the central axis L of the regular segment 621. The regular segment 621 includes two parallel straight edges 6211 and 6212, which are spaced apart. The outer contour of the irregular segment 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 extends integrally from the straight edge of the regular segment. The second side 6222 is arc-shaped, with its concave surface facing outwards from the feed plate 62. The convex surfaces of the second sides 6222 of the two irregularly segmented sections 622 are arranged opposite each other. The third side 6223 is a straight edge, and the intersection point of the extension line of the third side 6223 and the extension line of the first side 6221 is the center of the circle containing the second side 6222. The fourth side 6224 is arc-shaped, with its convex surface facing the first side 6221. One end of the fourth side 6224 is connected to the third side 6223, and the other end is connected to the second straight edge 6212 of the regularly segmented section 621.

[0189] After the aforementioned blanking plate 62 is wound into a semi-cylindrical section 61, the first straight edge 6211 and the second straight edge 6212 are formed into the two outlines of the first unit 6115, and the two fourth edges 6224, the two third edges 6223 and the two second edges 6222 are formed into the outlines of the second unit 6116.

[0190] Preferably, the central angle of the second side 6222 is 90 degrees, that is, the second side 6222 is a quarter circle.

[0191] This embodiment also provides a method for forming a tank body, which is obtained by welding the cylindrical section 61 of the present invention, including the following steps:

[0192] A blanking plate 62 is cut out. The blanking plate 62 is a flat plate, including a regular segment 621 and two irregular segments 622 integrally disposed at both ends of the regular segment 621. The regular segment 621 is rectangular, and the two irregular segments 622 are symmetrically distributed along the central axis L of the regular segment 621. The regular segment 621 includes two parallel straight edges 6211 and 6212, and the two straight edges 6211 and 6212 are spaced apart. The outer contour of the irregular segment 622 includes a first edge 6221, a second edge 6222, a third edge 6223, and a fourth edge 6224 connected in sequence. Among them, the first edge 6221 is a straight edge and extends integrally from the straight edge of the regular segment. The second side 6222 is arc-shaped, with its concave surface facing outwards from the feed plate 62. The convex surfaces of the second sides 6222 of the two irregularly segmented sections 622 are arranged opposite each other. The third side 6223 is a straight edge, and the intersection point of the extension line of the third side 6223 and the extension line of the first side 6221 is the center of the circle containing the second side 6222. The fourth side 6224 is arc-shaped, with its convex surface facing the first side 6221. One end of the fourth side 6224 is connected to the third side 6223, and the other end is connected to the second straight edge 6212 of the regularly segmented section 621.

[0193] The blanking plate 62 is rolled into a semi-cylindrical section 611 by aligning and bringing the third sides 6223 of the two irregular segments 622 close together, so that the semi-cylindrical section 611 includes a cylindrical first unit 6115 and a semi-conical second unit 6116, and the central axis of the first unit 6115 is perpendicular to the central axis of the second unit 6116.

[0194] Specifically, when the blanking plate 62 is rolled into a semi-cylindrical section 611, it can be directly rolled into a semi-cylindrical section 611 using a combination mold. Alternatively, the first unit 6115 can be rolled into a mold first, and then the second unit 6116 can be rolled into a second mold using a lifting device. Or, the second unit 6116 can be rolled into a mold first, and then the first unit 6115 can be rolled into a second mold using a lifting device.

[0195] Two half-sections 611 of the same height are welded together along the axis to form a single section 61.

[0196] Specifically, the welding between the two semi-cylinder sections 611 is a circumferential weld, which is conducive to mechanized welding.

[0197] Multiple cylindrical sections 61 are assembled and welded together to form a tank for loading materials.

[0198] Specifically, the welding between sections 61 is also a circumferential weld, which is conducive to mechanized welding.

[0199] In this embodiment, the tank body is formed by integrally winding a blank sheet, welding two prefabricated semi-cylindrical sections together to form a cylindrical section, and finally splicing the cylindrical sections together along their own cylindrical axial direction. The weld between the two semi-cylindrical sections is a circumferential weld, and the weld between two adjacent cylindrical sections is also a circumferential weld, which facilitates mechanized welding and thus improves the production efficiency of the tank body.

[0200] Meanwhile, the forming methods of both the semi-cylindrical section and the cylindrical section eliminate the phenomenon of reduced effective space for loading materials inside the tank due to the added plate material during the splicing and welding of the cylindrical and conical structures, thus increasing the effective volume inside the tank. Because the inside of the cylindrical section is smooth, materials can flow smoothly to the bottom of the section, eliminating dead zones during unloading and resulting in cleaner unloading.

[0201] In this embodiment, the two half-sections 611 of the cylindrical section 61 have the same axial dimensions.

[0202] In other embodiments, the two half-sections 611 of the cylindrical section 61 may have different dimensions along the axial direction. For example, the rear cylindrical section in the first embodiment of the tank body, i.e. Figure 2 The left end of the cylindrical section also includes two half-cylinder sections, namely the left half-cylinder section and the right half-cylinder section, and the difference between the left half-cylinder section and the right half-cylinder section is that their dimensions are different along the axial direction.

[0203] Second embodiment of the cylinder section

[0204] The difference between this embodiment and the first embodiment of the cylindrical section is that the semi-cylindrical section is formed by pressing a transition surface at the junction of the first unit and the second unit before the blanking plate is wound and formed.

[0205] Specifically, a blanking plate located in a plane is press-formed to create a transition surface, making the blanking plate into multiple parts located on multiple planes, and then rolled into shape. The transition surface is strip-shaped. After the blanking plate is rolled into a semi-cylindrical section, this transition surface forms the intersection line of the first unit and the second unit. The intersection line refers to the line of intersection formed on the surface when two three-dimensional structures intersect. In this embodiment, the two three-dimensional structures refer to the first unit and the second unit, therefore, the intersection line refers to the line of intersection formed on the surface when the first unit and the second unit intersect.

[0206] See 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 section. The difference is that the blanking plate in this embodiment is first pressed to form a transition surface, which can be shown as the dotted line in the figure.

[0207] The blanking plate is generally a flat plate with uniform material thickness. In order to improve the local strength of the blanking plate at the stretching position, a reinforcing plate is also provided on the inner side of the stretching position of the blanking plate when winding the half-cylinder section and pressing the transition surface.

[0208] Alternatively, the blanking plate can be a plate with uneven thickness, where the thickness at the stretching location is greater than at other locations, thereby improving the local strength at the stretching location and ensuring that it still meets the overall strength requirements after stretching. In practice, the blanking plate can be made by welding together multiple sheets of different thicknesses, or it can be integrally formed using special processes, such as 3D printing.

[0209] In this embodiment, the method for forming the can body includes the following steps before rolling the blanking plate:

[0210] First, press out a transition surface at the junction of the first unit and the second unit.

[0211] When pressing out the transition surface, a reinforcing plate is also welded inside the stretching position of the blanking plate.

[0212] The tube is then rolled into a semi-cylindrical section, with the reinforcing plate positioned inside the semi-cylindrical section.

[0213] The remaining steps are the same as those in the first embodiment of the cylindrical section.

[0214] The molding method described in this embodiment further reduces the molding difficulty of the semi-cylindrical section.

[0215] Other technical features of the cylindrical section can be referred to in the first embodiment of the cylindrical section, and will not be described in detail here.

[0216] Third embodiment of the cylinder section

[0217] See Figure 83The difference between this embodiment and the first embodiment of the cylindrical section is that the semi-cylindrical section 711 is formed by welding the upper part 7117 and the lower part 7118.

[0218] In this embodiment, the upper part 7117 constitutes the first unit, and the lower part 7118 constitutes the second unit. The semi-cylindrical section 711 can be obtained by welding the upper part 7117 and the lower part 7118 in the vertical direction.

[0219] The upper part 7117 is arc-shaped with an opening at its bottom, and the lower part 7118 is located at the opening.

[0220] Specifically, the method for forming the tank body by molding the cylindrical section in this embodiment, i.e., the tank body forming method, includes the following steps:

[0221] Cut out the first blanking plate. The first blanking plate is flat and square.

[0222] Specifically, the first blanking plate is obtained by cutting according to the preset size.

[0223] Cut out the second blanking plate. The second blanking plate is flat, while the first blanking plate is fan-shaped.

[0224] Specifically, the second blanking plate is obtained by cutting according to the preset size.

[0225] The first blanking plate is rolled into shape to form the upper part 7117, and the second blanking plate is rolled into shape to form the lower part 7118. The upper part 7117 and the lower part 7118 are welded together in the vertical direction to form a semi-cylindrical section, such that the semi-cylindrical section includes a cylindrical first unit and a semi-conical second unit, and the central axis of the first unit is perpendicular to the central axis of the second unit.

[0226] Two half-sections of the same height are welded together along the axis to form a single section.

[0227] Multiple cylindrical sections are assembled and welded together to form a tank for loading materials.

[0228] In this embodiment, the half-cylinder section is welded together with the upper part 7117 and the lower part 7118, and the two are welded face to face, with a large space for welding operation and convenient operation.

[0229] See Figure 84 In other embodiments, one side of the upper part 7117 can be sealed, that is, one side of it has a closed ring structure, which increases the connection strength between the upper part 7117 and the lower part 7118.

[0230] Other technical features of the cylindrical section can be referred to in the first embodiment of the cylindrical section, and will not be described in detail here.

[0231] Fourth embodiment of the cylinder section

[0232] See Figure 85 The difference between this embodiment and the third embodiment of the tank is that the upper part 8117 and the lower part 8118 of the cylindrical section have different structures.

[0233] Specifically, the lower part 8118 includes a semi-conical part and arc-shaped parts located at both ends of the semi-conical part. The two arc-shaped parts and the upper part 8117 enclose each other to form the first unit, and the semi-conical part forms the second unit.

[0234] That is, compared to the third embodiment of the cylindrical section, the central angle of the upper part 8117 in this embodiment is smaller.

[0235] The method of forming the tank using cylindrical sections can be referred to the description in the third embodiment of the cylindrical section, and will not be repeated here.

[0236] See Figure 86 In other embodiments, one side of the upper part 8117 can be sealed, that is, one side of it has a closed ring structure, which increases the connection strength between the upper part 8117 and the lower part 8118.

[0237] 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.

[0238] Fifth embodiment of the cylinder section

[0239] The difference between this embodiment and the first embodiment of the tank is that the cylindrical section 91 also includes a reinforcing ring 912.

[0240] 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.

[0241] 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.

[0242] The fitting part 9121 and the transition part 9122 can be integrally formed or welded together.

[0243] 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.

[0244] In another embodiment, the reinforcing ring may consist only of the fitting portion 9121.

[0245] 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.

[0246] That is, the number of reinforcing rings 912 included in the cylindrical section 91 can be set according to actual needs.

[0247] 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.

[0248] Sixth embodiment of the cylinder section

[0249] 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.

[0250] The reinforcing ring connects to the upper part of the cylinder section, which not only increases the connection strength between two adjacent cylinder sections, but also makes the transition between cylinder sections with inconsistent dimensions smooth. It also prevents material from accumulating at the bottom reinforcing part due to the reinforcing ring at the bottom, thus ensuring clean unloading.

[0251] Other technical features of the cylindrical section can be referred to in the fifth embodiment of the cylindrical section, and will not be described in detail here.

[0252] Seventh embodiment of the cylindrical section

[0253] In this embodiment, the cylinder section refers to the transition cylinder section. Figure 104 and Figure 105 Schematic diagrams of the transition section 64 at different angles are shown. Figure 106-111 A six-sided view of the transition section 64 is shown, in conjunction with... Figures 82-89 The transition section 64 includes a cylindrical body 641 with a cylindrical profile and a transition section 642 located at the lower part of the cylindrical body 641. The cylindrical body 641 is connected to the first unit of the adjacent cylindrical section, the transition section 642 is inclined toward the adjacent cylindrical section, and the transition section 642 is connected to the second unit of the adjacent cylindrical section.

[0254] The cylindrical section 641 is an open arc shape with an opening at its bottom. Specifically, the concave surface of the cylindrical section 641 faces downward, and the central angle of the cylindrical section 641 is greater than 180 degrees. Furthermore, the cylindrical section 641 is adapted to the adjacent cylindrical section.

[0255] The cylindrical part 641 can be integrally rolled into shape from a single sheet metal.

[0256] The transition section 642 is provided at the opening, while the opening of the sealing cylinder section 641 is blocked, so that the transition cylinder section 34 is closed.

[0257] Specifically, the transition section 642 is fan-shaped, with its concave surface facing the cylindrical body, i.e., upward.

[0258] The transition section 642 is inclined, and it is inclined downward along the direction close to the adjacent cylinder section.

[0259] The transition section 642 can be integrally wound into shape from a single sheet material.

[0260] The transition section 64 can be obtained by welding the cylindrical body 641 to the transition section 642.

[0261] Furthermore, the cylindrical portion 641 extends downward to form two ear plates that conceal the transition portion 642 therein, and the bottom of the transition portion 642 extends downward beyond the bottom of the cylindrical portion 641.

[0262] The transition section 64 is located between two adjacent sections. By tilting the transition section 642, the material slides down to the adjacent section for unloading. This allows the tank to meet the volume requirements while avoiding the increase in tank volume and weight, as well as the waste of raw materials. This reduces the tank weight and saves costs.

[0263] See Figure 112 The two transition sections 64 can also be welded together relative to their vertical split surfaces to form a whole. After the two transition sections 64 are connected, the tops of the two transition parts 642 are connected, so that the cross-section of the two transition parts 642 is inverted V-shaped, that is, each transition part 642 is inclined towards the adjacent section.

[0264] Furthermore, the two transition cylinder sections 64 are symmetrically distributed about the vertical midpoint.

[0265] Eighth embodiment of the cylindrical section

[0266] Figure 113 A schematic diagram of the transition section 74 is shown. Figure 114 A cross-sectional view of the transition section 74 is shown. Figures 115-120 A six-sided view of transition section 74 is shown; see reference. Figure 113-120 The difference between the transition section 74 in this embodiment and the section in the seventh embodiment is that the cylindrical body 741 is a closed annular ring, and the transition section 742 is an inverted V-shape.

[0267] Specifically, the cylindrical section 741 has a closed, continuous ring structure. This cylindrical section 741 can be integrally wound from a sheet metal.

[0268] The transition section is located inside the cylindrical section 741 and is connected to the inner wall of the cylindrical section 741.

[0269] Specifically, the transition section is inverted V-shaped, including two inclined surfaces arranged at an acute angle to each other. The junction of the two inclined surfaces arches relative to the inner wall of the cylindrical section 741, forming a sharp angle. The edges of the two inclined surfaces connect with the inner surface of the cylindrical section 741 and cover a portion of the cylindrical section 741. The portion of the cylindrical section 741 covered by the transition section has weight-reducing holes 743 to reduce the weight of the transition section 74, thereby reducing the weight of the entire tank.

[0270] The two inclined surfaces of the transition section and the cylinder section 741 enclose a cavity for loading powder materials. The two inclined surfaces provide unloading guidance for the powder materials, allowing them to slide along the two inclined surfaces into the cylinder section adjacent to the transition cylinder section 74, thereby realizing the loading and unloading of materials.

[0271] In this embodiment, the slope surface is a straight plate. In other embodiments, the slope surface may also be an arc-shaped plate with an inclination angle.

[0272] The two sloping surfaces can be formed as a single piece by bending a sheet of material, or they can be formed separately and then welded together to form an angled structure.

[0273] When the entire assembly of the aforementioned transition cylindrical section 74 is connected to adjacent cylindrical sections, the cylindrical body 741 forms a closed annular structure, which helps to improve the overall strength of the tank. Furthermore, since adjacent cylindrical sections can be circumferentially welded together, it facilitates automated production.

[0274] In other embodiments, the transition section may also be formed by a ramp surface that slopes from one side of the cylinder section 741 in the axial direction to the other side. In practical applications, the lower end of the ramp surface may face either the adjacent cylinder section in front or the adjacent cylinder section in the rear.

[0275] Other technical features of the cylindrical section can be referred to in the seventh embodiment of the cylindrical section, and will not be described in detail here.

[0276] Ninth embodiment of the cylindrical section

[0277] Figure 121 A schematic diagram of the cylindrical section assembly is shown. Figures 122-127 The diagram shows a six-sided view of the cylindrical section assembly, combined with... Figures 121-127 In this embodiment, the cylindrical section assembly consists of two transition cylindrical sections 84.

[0278] Each transition section 84 includes a cylindrical body portion 841 with a cylindrical profile and a transition portion 842 located below the cylindrical body portion 841. The cylindrical body portion 841 is connected to the first unit of the adjacent cylindrical section, the bottom surface of the transition portion 842 is inclined towards the adjacent cylindrical section, and the transition portion 842 is connected to the second unit of the adjacent cylindrical section.

[0279] In the cylindrical section assembly, two transition cylindrical sections 84 are arranged and connected along the axial direction of the cylindrical body 841. The cylindrical body 841 of the two transition cylindrical sections 84 has the same diameter. The transition part 842 of the two transition cylindrical sections 84 is an inclined surface that is inclined relative to the axial direction. The joint of the two inclined surfaces forms a ridge that protrudes from the internal space of the cylindrical section assembly, so that the two transition cylindrical sections 84 are gradually widened outward from the joint of the two into a trumpet shape.

[0280] In this embodiment, the transition section 84 can be obtained by welding the upper and lower parts. The upper part is cylindrical. Alternatively, the upper part is generally cylindrical, meaning it has downwardly sloping arc-shaped structures at both ends. The lower part is an arc-shaped plate with an inclined angle. Alternatively, the lower part can also be a straight plate.

[0281] As can be seen from the above technical solution, the advantages and positive effects of the present invention are as follows:

[0282] By grouping the overall tank structure into different specifications according to different volumes, standard and universal cylindrical sections with cylindrical cones of different volumes are formed. Then, the cylindrical sections of different volumes are arranged and combined laterally to form tanks of different volumes. Finally, the cylindrical sections of the combined tanks are welded to form an integral tank.

[0283] The innovative process of forming the cylindrical section involves dividing it into two parts according to the axial symmetry plane of the cone. Each part is then formed into two semi-cylindrical sections, which are then butt-welded together to form a single cylindrical section. This significantly simplifies the forming process of individual cylindrical sections, allowing for the integral rolling and forming of the semi-cylindrical sections. It also optimizes the cross-sections at both ends of each individual cylindrical section, ensuring that both ends are identical rings. Therefore, adjacent cylindrical sections only need to be welded using a circumferential welding method, improving the standardization and versatility of the production process, facilitating mechanized and automated welding, and increasing the production efficiency of the tanks. Secondly, by combining different cylindrical sections laterally and uniformly adopting a longitudinal circumferential weld method, the welding quality of the product is effectively improved, thereby improving the overall quality of the product. Thirdly, by using standard and universally applicable cylindrical sections of various specifications for circumferential welds, the structural form of product serialization and standardization is effectively improved, and the efficiency of product design and management is enhanced. Finally, using standard and universally applicable cylindrical sections of various specifications for circumferential welds can effectively avoid various defects caused by traditional cylindrical and conical splicing and welding, such as non-standardization, uneven joints, high welding labor intensity, high splicing and riveting difficulty, and poor product welding quality.

[0284] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the 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.
