Description

Technical Field

[0001] This utility model relates to the technical field of storage tanks, and in particular to a production equipment for an integrally molded conical bottom of a mixing storage tank. Background Technology

[0002] Storage tanks made of plastic materials such as PP (polypropylene) and PPH (reinforced polypropylene) have advantages such as corrosion resistance, high strength, leak resistance, high and low temperature resistance, long service life, low cost, and light weight. They are widely used in chemical, petroleum, chlor-alkali, dye, pharmaceutical, light industry, and metallurgical fields.

[0003] Currently, the production process of the conical bottom of storage tanks is generally as follows: First, plastic granules (such as PPH granules) are melted and extruded into strips, then wrapped around the mold in circles, with adjacent circles of material adhering to each other. After cooling and solidification, the tank wall is formed, and finally the tank top and tank bottom are installed on the tank body.

[0004] In existing technologies, a support frame is needed to enable the mold to rotate. After the material has cooled and solidified on the mold, the support frame needs to be removed before demolding, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0037] like Figure 1 , Figure 2 and Figure 10As shown, in one embodiment of this utility model, a one-piece molded conical bottom production device for a stirred tank is provided. Specifically, the one-piece molded conical bottom production device for a stirred tank includes a mold 9, a frame 1, and an extrusion device 2. The mold 9 includes a frame 93 and a conical mold 91, the conical mold 91 being rotatably mounted on the frame 93 around its own axis. The frame 1 and the conical mold 91 are slidably arranged relative to each other, and the direction of their relative sliding is parallel to the generatrix of the conical mold 91 facing the frame 1. The extrusion device 2 is mounted on the frame 1 and can coat the conical mold 91 with a strip of molten material through a die, forming the one-piece molded conical bottom 02 of the stirred tank.

[0038] In this embodiment, the conical die 91 rotates on the frame 93, and the frame 1 supports the extrusion device 2, which slides relative to the conical die 91 (preferably, the frame 1 supports the extrusion device 2). The strip-shaped molten material (e.g., molten PPH) extruded from the orifice of the extrusion device 2 can be coated onto the conical die 91 along a spiral trajectory. After the molten material solidifies on the conical die 91, it forms an integrally molded tank conical bottom 02. The integrally molded tank conical bottom 02 produced in this embodiment is integrally molded without weld seams, eliminating the safety hazard of cracking due to weld seams and ensuring that the structural strength of the conical bottom meets the usage requirements.

[0039] like Figure 2 , Figure 5 and Figure 8 As shown, in one embodiment of this utility model, a wire supply device 3 is also included. During the production of the one-piece molded tank cone bottom 02, the wire supply device 3 can supply wire to the cone mold 91. The wire can be embedded in the molten material. After the molten material solidifies, the wire can be spirally wound around the cone bottom, serving as a reinforcing wire to improve the structural strength of the cone bottom, enhance its resistance to deformation, and improve its mechanical strength and impact resistance. Specifically, the wire supply device 3 includes a wire reel frame 31 and a wire distributor 32. The wire reel frame 31 includes a mounting frame 311 and a wire supply wheel 312. The wire supply wheel 312 is rotatably mounted on the mounting frame 311, and wire is wound on the wire supply wheel 312 to supply wire to the cone mold 91. The wire distributor 32 is mounted on the frame 1, located above the mold opening. The wire distributor 32 has a guide groove, and the wire on the wire supply wheel 312 is supplied to the cone mold 91 via the wire distributor 32. When the wire passes through the splitter 32, it passes through the guide groove. The splitter 32 can provide guidance and a certain tension to the wire through the guide groove. Preferably, in this embodiment, the wire is aramid cord impregnated with a bonding adhesive, which has sufficient strength to meet the usage requirements and is easy to bond with molten materials (such as molten PPH). There are multiple feed rollers 312, and the number of guide grooves on the splitter 32 is not less than the number of feed rollers 312, which can realize the synchronous winding of multiple strands of aramid cord and improve the structural strength of the integrally molded tank cone bottom 02.

[0040] Furthermore, in this embodiment, the wire reel frame 31 also includes a clamping assembly. Specifically, the clamping assembly includes an adjusting spring 313 and an adjusting nut 314. The wire feeding reel 312 is rotatably mounted on one side of the wire reel frame 31 via an axle. The adjusting spring 313 and the adjusting nut 314 are mounted on the axle on the other side of the wire reel frame 31, with the adjusting spring 313 positioned between the wire reel frame 31 and the adjusting nut 314. During production, the compression of the adjusting spring 313 can be adjusted using the adjusting nut 314, thereby adjusting the clamping force of the adjusting spring 313 and the friction force when the wire feeding reel 312 rotates. In this embodiment, by adjusting the friction force when the wire feeding reel 312 rotates using the clamping assembly, the tension force during wire supply can be adjusted, ensuring the consistency of the force on the wire within the integrally formed tank cone bottom 02, and thus ensuring consistent structural strength throughout the cone bottom.

[0041] Furthermore, in this embodiment, the reel frame 31 also includes a guide ring, which is mounted on the mounting frame 311 and can provide guidance for the wire, preventing multiple strands of wire from getting tangled during supply and affecting the production progress.

[0042] like Figure 1 and Figure 6 As shown, in one embodiment of this utility model, a hot mold device 6 is also included. The hot mold device 6 can heat the conical mold 91 before coating the molten material, thereby increasing the temperature of the conical mold 91 itself and facilitating demolding of the one-piece molded tank bottom using the principle of thermal expansion and contraction. Specifically, the hot mold device 6 includes a hot mold frame, a flame gun 63, a gas supply pipe, and a gas cylinder. The hot mold frame is mounted on the frame 1, providing a mounting position for the flame gun 63. The flame gun 63 is mounted on the hot mold frame and can spray flames onto the outer surface of the conical mold 91 to heat the conical mold 91. One end of the gas supply pipe is connected to the flame gun 63, and the other end is connected to the gas cylinder, so that the gas in the gas cylinder can be supplied to the flame gun 63 through the gas supply pipe. In this embodiment, the conical mold 91 is heated by flame spraying, which has a simple structure and can quickly increase the temperature of the conical mold 91, saving time and thus improving production efficiency.

[0043] Furthermore, in this embodiment, the hot mold frame includes a first hot mold frame 61 and a second hot mold frame 62. Multiple flamethrowers 63 are mounted on both the first hot mold frame 61 and the second hot mold frame 62. The first hot mold frame 61 is mounted on the frame 1, and the upper end of the second hot mold frame 62 is connected to the lower end of the first hot mold frame 61 by bolts. In this embodiment, the second hot mold frame 62 and the first hot mold frame 61 can be rotatably connected by manually adjusting the bolt connection. Adjusting the angle between the first hot mold frame 61 and the second hot mold frame 62 allows for adjustment of the angle between the multiple flamethrowers 63, making the flame angle of the multiple flamethrowers 63 more closely match the conical mold 91, improving the utilization rate of flame heat, and ensuring the uniformity of heating of the conical mold 91.

[0044] Furthermore, in this embodiment, a regulating valve is installed on the gas pipeline. During production, the gas flow rate can be adjusted by the regulating valve, the gas can be turned on and off, and the size of the heating flame can be adjusted by the flow control.

[0045] like Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment of this utility model, a delayed curing device 7 is also included. During production, the delayed curing device 7 is used to heat the molten material on the conical mold 91, thereby delaying the curing of the molten material. When the molten material is coated in a spiral shape, it can make the molten material of adjacent spirals bond together more tightly, improving the connection strength of the cone bottom. Specifically, the delayed curing device 7 includes a delayed curing frame and a delayed curing disc 71. The delayed curing frame is mounted on the frame 1, providing a mounting position for the delayed curing disc 71. The delayed curing disc 71 is mounted on the delayed curing frame and is equipped with a heating tube. When the heating tube is energized, it can heat the molten material on the conical mold 91, delaying the curing time of the molten material and making the bond between the molten materials of adjacent spirals more firm.

[0046] Furthermore, in this embodiment, the delayed curing frame includes a square frame 72, a first guide block 74, a first lead screw 73, a first nut, and a disc rod 76. The length direction of the square frame 72 is parallel to the sliding direction of the frame 1; both ends of the first guide block 74 are slidably engaged with the square frame 72, and the disc rod 76 is connected to the first guide block 74. The first lead screw 73 is rotatably mounted on the square frame 72, and the axis of the first lead screw 73 is parallel to the length direction of the square frame 72. The first nut is mounted on the first guide block 74, and the first nut is threadedly engaged with the first lead screw 73. The disc rod 76 is perpendicular to the first lead screw 73, and a delayed curing disc 71 is mounted on one end of the disc rod 76. In this embodiment, by rotating the first lead screw 73, the first nut can drive the first guide block 74 to slide on the square frame 72, thereby adjusting the relative distance between the delayed curing disc 71 and the orifice in the generatrix direction of the cone mold 91, making the heating range adjustment of the delayed curing disc 71 more flexible, thereby improving the forming quality of the cone bottom. Preferably, a first handwheel is installed at one end of the first lead screw 73, which allows for manual adjustment of the position of the delayed curing disc 71 during production, making operation more direct and convenient. The delayed curing disc 71 is arc-shaped, with the center of the arc facing the conical mold 91, which can fit the outer arc surface of the conical mold 91, resulting in more uniform heating. The delayed curing disc 71 is equipped with multiple heating tubes, which can improve heating efficiency and heating capacity, and ensure heating quality.

[0047] Furthermore, in this embodiment, the first guide block 74 is provided with a connecting hole and a positioning bolt 75 communicating with the connecting hole. The disc rod 76 is inserted into the connecting hole, with a clearance fit, and abuts against the positioning bolt 75. In this embodiment, the disc rod 76 has a clearance fit with the connecting hole. Loosening the positioning bolt 75 can adjust the position of the disc rod 76 in the connecting hole, and tightening the positioning bolt 75 can fix the position of the disc rod 76 in the connecting hole. This allows adjustment of the distance between the delayed curing disc 71 and the surface of the cone mold 91, so that the delayed curing disc 71 can move closer to or further away from the cone mold 91 as needed, thereby adjusting the heating intensity.

[0048] like Figure 1 and Figure 6 As shown, in one embodiment of this utility model, an adjustment mechanism 4 is also included. The adjustment mechanism 4 is mounted on the frame 1, and both the hot mold device 6 and the delayed curing device 7 are mounted on the adjustment mechanism 4. During production, the adjustment mechanism 4 can adjust the posture of the hot mold device 6 and the delayed curing device 7. Specifically, the adjustment mechanism 4 includes a swing rod 41, a second nut, a second lead screw 42, an adjustment motor 44, and an adjustment reducer 43. The swing rod 41 includes a horizontal bar and a vertical bar formed as one piece, with one end of the vertical bar connected to one end of the horizontal bar, and the vertical bar located below the horizontal bar. The hot mold frame is mounted on one side of the free end of the horizontal bar, and the delayed curing frame is mounted on the other side of the free end of the horizontal bar. The vertical bar is hinged to the frame 1, and the lower end of the vertical bar is rotatably mounted with a second nut; the adjustment reducer 43 is hinged to the frame 1, and both the adjustment motor 44 and the second lead screw 42 are mounted on the adjustment reducer 43, with the second lead screw 42 also threadedly connected to the second nut. During production, the adjusting motor 44 drives the second lead screw 42 to rotate via the adjusting reducer 43. This changes the engagement position of the second nut and the second lead screw 42, thereby causing the swing rod 41 to swing. This allows adjustment of the angle between the hot mold device 6 and the delayed curing device 7 and the surface of the cone mold 91. Furthermore, in this embodiment, the swing angle of the swing rod 41 is adjusted via the second nut, the second lead screw 42, the adjusting motor 44, and the adjusting reducer 43. This adjustment method possesses self-locking capability, resulting in greater energy efficiency.

[0049] Furthermore, in this embodiment, the swing rod 41 also includes a diagonal rod, which is integrally formed with the horizontal rod and the vertical rod. One end of the diagonal rod is connected to the vertical rod, and the other end of the diagonal rod is connected to the horizontal rod, which can improve the structural strength of the swing rod 41 and ensure the reliability of the installation of the thermal molding device 6 and the delayed curing device 7.

[0050] like Figure 2 and Figure 8As shown, in one embodiment of this utility model, a shaping mechanism 5 is also included. During production, after the molten material is coated on the surface of the conical mold, the shaping mechanism 5 can shape the molten material on the conical mold 91. Specifically, the shaping mechanism 5 includes a first shaping mechanism, which includes a first shaping frame 51, a first shaping roller 53, a first shaping cylinder 52, a guide frame, and a guide roller 54. The first shaping frame 51 is hinged to the machine frame 1, and the first shaping roller 53 is rotatably mounted on the first shaping frame 51. One end of the first shaping cylinder 52 is hinged to the machine frame 1, and the other end is hinged to the first shaping frame 51. The guide frame is hinged to the first shaping frame 51, and the guide roller 54 is rotatably mounted on the guide frame. During production, the strip of molten material extruded from the die first passes through the guide roller 54, and then is coated onto the conical mold 91 via the first shaping roller 53. The guide roller 54 is spindle-shaped, with a large diameter in the middle and gradually decreasing diameters on both sides, which can widen the strip of molten material. The molten material deforms and coats the surface of the conical mold 91 between the conical mold 91 and the first shaping roller 53. The first shaping roller 53 can shape the surface of the molten material coated on the conical mold 91. When the first shaping cylinder 52 retracts, the first shaping roller 53 is close to the conical mold 91; when the first shaping cylinder 52 extends, the first shaping roller 53 moves away from the conical mold 91. By controlling the first shaping frame 51 through the first cylinder, the distance between the first shaping roller 53 and the conical mold 91 can be controlled, allowing for flexible adjustment of the coating thickness and the pressure during plasticization.

[0051] Furthermore, in this embodiment, there are two first shaping cylinders 52, which are symmetrically distributed on both sides of the first shaping frame 51 and work together to ensure the reliability and accuracy of shaping, and to ensure that the first shaping frame 51 is subjected to balanced force on both sides.

[0052] like Figure 8 As shown, in one embodiment of this utility model, the shaping mechanism 5 further includes a second shaping mechanism, which can assist the first shaping mechanism in shaping the molten material on the cone mold 91. Specifically, the second shaping mechanism is located below the first shaping mechanism and includes a second shaping frame, a second shaping roller 59, and a second shaping cylinder. The second shaping frame is hinged to the frame 1, and the second shaping roller 59 is rotatably mounted on the second shaping frame. One end of the second shaping cylinder is hinged to the frame 1, and the other end is hinged to the second shaping frame. When the second shaping cylinder extends, the second shaping roller 59 is close to the cone mold 91; when the second shaping cylinder retracts, the second shaping roller 59 moves away from the cone mold 91. This embodiment, by setting the second shaping mechanism, can assist the first shaping mechanism in shaping the molten material, thereby improving the surface quality of the integrally formed tank cone bottom 02.

[0053] Furthermore, in this embodiment, the second shaping frame includes a shaping frame body, guide rods 55, a second guide block 57, a third nut, a third lead screw 56, and a connecting rod. One end of the shaping frame body is hinged to the machine frame 1, and the other end is hinged to the second shaping cylinder. Two guide rods 55 are mounted on the shaping frame body, arranged in parallel, with their axes parallel to the sliding direction of the machine frame 1. The second guide block 57 slides with the guide rods 55. The third nut is installed inside the second guide block 57. The connecting rod is connected to the second guide block 57. The second shaping roller 59 is rotatably mounted on the connecting rod, with its axis perpendicular to the axis of the guide rod 55. The third lead screw 56 is rotatably mounted on the shaping frame body and threadedly connected to the third nut, with its axis parallel to the axis of the guide rod 55. Preferably, there are two second shaping cylinders, symmetrically distributed on both sides of the second shaping frame, ensuring balanced force and accurate and reliable operation of the second shaping frame. A second handwheel is installed at one end of the third lead screw 56 for manual adjustment. In this embodiment, by adjusting the third lead screw 56, the position of the second shaping roller 59 can be adjusted along the generatrix of the conical mold 91, thereby adjusting the relative position of the second shaping roller 59 and the first shaping roller 53. This allows the second shaping roller 59 to shape synchronously with or lag behind the first shaping roller 53.

[0054] Furthermore, in this embodiment, the second guide block 57 is provided with a threaded hole, and the connecting rod is a threaded rod installed in the threaded hole. A positioning nut 58 is provided on the connecting rod. During debugging, the mating position of the connecting rod and the threaded hole can be adjusted, thereby adjusting the distance between the second shaping roller 59 and the cone mold 91. After adjustment, the positioning nut 58 is tightened against the second guide block 57 to fix the current position of the connecting rod. In this embodiment, by providing the threaded rod, threaded hole, and positioning nut 58, the adjustable degrees of freedom of the second shaping roller 59 are expanded, enabling compensation and adjustment of the movement of the second shaping cylinder.

[0055] like Figure 1 and Figure 9As shown, in one embodiment of this utility model, a cutting device 8 is also included. During production, the cutting device 8 can cut both ends of the one-piece molded tank cone bottom 02 along the axial direction, eliminating the need for manual cutting after demolding, ensuring cutting quality, and improving automation. Specifically, the cutting device 8 includes a mounting base and a cutting module 81. The mounting base is mounted on the frame 1, and the cutting module 81 is mounted on the mounting base. The cutting module 81 is equipped with a cutting head, which can cut the one-piece molded tank cone bottom 02 when rotating. In this embodiment, the mounting base provides an installation position for the cutting module 81. The cutting module 81 is pneumatically driven, and the cutting head rotates under the drive of compressed air, cutting the cone bottom during rotation.

[0056] Furthermore, in this embodiment, the mounting base includes a first base 88, a transmission base, and a cutting cylinder 87. The first base 88 is mounted on the frame 1 and has a first slider. The transmission base has a cutting module 81 mounted on it, and a first guide rail 86 at its bottom, which slides in conjunction with the first slider. The cutting cylinder 87 is mounted on the frame 1 and connected to the transmission base. The cutting cylinder 87 provides power for the sliding of the transmission base. When the cutting cylinder 87 extends, the transmission base slides toward the conical mold 91; when the cutting cylinder 87 retracts, the transmission base moves away from the conical mold 91. In this embodiment, the cutting cylinder 87 controls the sliding of the cutting module 81, enabling large-stroke adjustment of the cutting module 81, and the adjustment action is rapid and accurate.

[0057] Furthermore, in this embodiment, the transmission base includes an adapter base 85, a fourth lead screw 84, a fourth nut, and a second base 82. A first guide rail 86 is mounted on the bottom of the adapter base 85, and a second guide rail 83 is provided on the adapter base 85. A cutting module 81 is mounted on the second base 82, and a second slider is provided at the bottom of the second base 82, which slides in cooperation with the second guide rail 83. The fourth lead screw 84 is rotatably mounted on the adapter base 85, and the fourth nut is mounted on the bottom of the second base 82, with the fourth lead screw 84 and the fourth nut threadedly connected. In this embodiment, the first guide rail 86 mounted at the bottom of the adapter base 85 increases the sliding range of the adapter base 85, extends its stroke, and prevents interference. When the fourth lead screw 84 rotates, the sliding of the second base 82 can be controlled by the fourth nut, thereby achieving small stroke adjustment of the cutting module 81, adjusting the depth of cut during conical bottom cutting, and ensuring a safe and reliable cutting process. Preferably, in this embodiment, the adapter 85 is provided with an abutment portion, and the end of the abutment portion is provided with an abutment wheel 89. During cutting, the abutment wheel 89 can abut against the integrally formed conical bottom 02 of the storage tank, providing a cutting reference. One end of the fourth lead screw 84 is provided with a third handwheel, which can be used to adjust the fourth lead screw 84.

[0058] like Figure 1 , Figure 10 and Figure 11 As shown, in one embodiment of this utility model, the mold 9 includes a frame 93, a conical mold 91, a bearing assembly 92, and a power assembly 94. The bearing assembly 92 is mounted on the frame 93, and the conical mold 91 has a mounting shaft along its axis. The bearing assemblies 92 are arranged in pairs and can be connected to both ends of the mounting shaft, reducing the resistance when the mounting shaft rotates and making the rotation of the conical mold 91 smoother. The power assembly 94 is mounted on the frame 93 and connected to the mounting shaft, providing power to drive the conical mold 91 to rotate.

[0059] Preferably, the conical mold 91 is made of metal and includes a conical mold wall, a cooling shroud, a mounting shaft, and supporting ribs. The smaller diameter end of the conical mold wall is closed, while the larger diameter end is open. The cooling shroud is detachably connected to the larger diameter end of the conical mold wall. The mounting shaft passes through the conical mold wall and is connected to the smaller diameter end. Multiple supporting ribs are used, with one end connected to the inner wall of the conical mold wall and the other end connected to the mounting shaft. In this embodiment, the conical mold 91 is hollow, facilitating heating, cooling, disassembly, and handling. The cooling shroud is detachably connected to the conical mold wall (for example, the cooling shroud can be snapped onto the larger diameter end of the conical mold wall, locking it to the outside of the conical mold wall and closing the opening). When the cooling hood is installed on the conical mold wall, it seals the wall, making the conical mold 91 a hollow cavity, facilitating heating and insulation. When the cooling hood is removed, the opening in the mold wall cools rapidly, allowing for easy demolding of the one-piece molded tank's conical bottom. The supporting keel is located inside the conical mold wall, supporting it between the inner wall and the mounting shaft, ensuring the structural strength of the conical mold 91.

[0060] Furthermore, in this embodiment, the bearing assembly 92 includes a bearing housing, a first bearing 923, a second bearing 924, a third bearing 926, and a locking rod 925. The bearing housing includes a first seat 921 and a second seat 922, with one side of the first seat 921 hinged to one side of the second seat 922. A locking rod 925 is hinged to the other side of the first seat 921, and a locking nut is provided on the locking rod 925. A slot that mates with the locking rod 925 is provided on the other side of the second seat 922. The first bearing 923 and the second bearing 924 are symmetrically mounted on the first seat 921, and the third bearing 926 is mounted on the second seat 922. The axis of the third bearing 926 lies on the plane of symmetry between the first bearing 923 and the second bearing 924. In this embodiment, the first seat 921 and the second seat 922 are hinged on one side and detachably connected on the other side. When the locking rod 925 is in the slot and the locking nut is in contact with the second seat 922, the first seat 921 and the second seat 922 can confine the mounting shaft between the first bearing 923, the second bearing 924 and the third bearing 926, ensuring smooth rotation of the mounting shaft. When the locking nut is loosened and the locking rod 925 is removed from the slot, the second seat 922 can be flipped open, and the mounting shaft can be removed from the bearing assembly 92 to demold the conical bottom. Preferably, an annular groove is provided on the circumferential surface of the mounting shaft, and the outer rings of the first bearing 923, the second bearing 924 and the third bearing 926 all abut against the bottom surface of the annular groove, which ensures smooth rotation of the mounting shaft and also provides axial positioning of the mounting shaft.

[0061] Furthermore, in this embodiment, the power assembly 94 includes a power motor, a power reduction gearbox, a driving gear, and a driven gear. The power reduction gearbox is mounted on the frame 93, the power motor is connected to the input shaft of the power reduction gearbox, and the driving gear is connected to the output shaft of the power reduction gearbox; the driven gear is mounted on one end of the mounting shaft, and the driving gear meshes with the driven gear. The power motor can drive the driving gear to rotate through the power reduction gearbox, and then drive the conical mold 91 to rotate through the driven gear meshing with the driving gear.

[0062] Please refer to Figure 12 , 13 The frame 93 includes a bottom frame 933, a first bracket 931, and a second bracket 932. The first bracket 931 and the second bracket 932 are fixedly connected to the bottom frame 933 at intervals. Two bearing assemblies 92 are respectively disposed on the first bracket 931 and the second bracket 932, thereby mounting the shaft between the two bearing assemblies 92. The power assembly is disposed on the first bracket 931.

[0063] In another embodiment of this utility model, the first bracket 931 includes a fixed part 934 and a rotating part 935. The lower end of the fixed part 934 is fixedly connected to the bottom frame 933. The upper end of the fixed part 934 forms a rotating base 936. The lower end of the rotating part 935 is rotatably connected to the upper side of the rotating base 936 via a rotating shaft and a universal joint, that is, the rotating part 935 can rotate around the axis of the rotating shaft and can also tilt in all directions. The power assembly 94 and one of the bearing assemblies 92 are both disposed on the upper side of the rotating part 935.

[0064] Furthermore, the rotating part 935 and the rotating base 936 can be rectangular, cylindrical, or other suitable shapes. The following detailed explanation uses a rectangular shape for both the rotating part 935 and the rotating base 936 as an example: The lower side of the rotating part 935 is flush with the upper side of the rotating base 936. A clearance groove 937 is provided on the upper side of the rotating base 936, extending from the upper side of the rotating base 936 to one of its vertical sides. The width of the clearance groove 937 matches the width of the rotating part 935, allowing the rotating part 935 to tilt only when aligned with the clearance groove 937. This tilts the bearing assembly 92 on its upper side and the mounting shaft connected to the bearing assembly 92, allowing the conical mold 91 to tilt towards the ground when the bearing assembly 92, away from the power assembly 94, releases the mounting shaft. Figure 13 In this design, only the width of plane A and the plane parallel to it is equal to the width of plane B of the clearance groove 937. Therefore, the cone mold 91 can only tilt towards the ground when plane A or the plane parallel to plane A rotates to a position aligned with the clearance groove 937. The rotating part 935 and the rotating base 936 facilitate demolding of the cone mold 91 by the operator, improving the ease of demolding operations. When the rotating part 935 rotates to other positions not aligned with the clearance groove 937, the upper side of the rotating base 936 restricts the tilting of the rotating part 935, ensuring that the cone mold 91 is stably mounted on the mounting shaft.

[0065] like Figure 10 As shown, in one embodiment of this utility model, the mold 9 further includes a cooling system. The cooling system can provide internal cooling for the conical mold 91, thereby causing the conical mold 91 to shrink upon cooling, facilitating rapid demolding of the conical bottom. Optionally, in this embodiment, the cooling system can be an air-cooling system, using a fan, blower, air conditioner, etc., to cool the conical mold 91; the cooling system can also be a liquid-cooling system, using water cooling to cool the conical mold 91; the cooling system can also use a combination of the above two methods to cool the conical mold 91.

[0066] Furthermore, in this embodiment, the cooling system adopts the principle of natural air cooling for natural demolding. After the molten material (ribbon-shaped PPH melt) is saturated and formed on the conical mold, the cooling hood is opened, and the conical mold wall is cooled by natural air, allowing the one-piece molded tank cone bottom to quickly separate from the conical mold 91. In this embodiment, demolding is performed using thermal expansion and contraction (during thermal expansion and contraction, the deformation of the metal conical mold is less than that of the one-piece molded tank cone bottom). During demolding, the shrinkage of the one-piece molded tank cone bottom due to cooling is greater than that of the conical mold 91, allowing the one-piece molded tank cone bottom to slide towards the smaller diameter end of the conical mold wall under the thrust of the conical mold 91 and thus detach.

[0067] Furthermore, in this embodiment, the cooling hood is provided with ventilation holes, which can be connected to cooling air. The amount of cooling air discharged into the cone mold 91 can be controlled as needed. The principle of cooling air intervention can control the demolding time, which can be fast or slow, and can be easily collected.

[0068] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, to facilitate smooth sliding of the frame 1, the bottom of the frame 1 is provided with a third guide rail 13, a third slider 14, a rack 15, a transmission gear, and a drive assembly. There are two third guide rails 13, arranged parallel to each other and parallel to the generatrix of the conical mold 91 facing the frame 1. There is one rack 15, connected to one of the third guide rails 13, and arranged parallel to the third guide rail 13. The drive assembly is mounted on the frame 1 and includes a connected drive motor and a drive reducer. The transmission gear is mounted on the drive reducer and meshes with the rack 15. During production, the drive assembly drives the transmission gear to rotate, allowing the transmission gear to roll along the rack 15, thereby causing the frame 1 to slide along the third guide rail 13. In this embodiment, the use of a gear and rack 15 for transmission ensures the smoothness of the frame 1's sliding; the use of the third guide rail 13 and the third slider 14 for guidance ensures the accuracy of the frame 1's sliding.

[0069] like Figure 1 and Figure 3 As shown, in this utility model, an electrical box 12 and a control panel 11 are installed on the frame 1. The control panel 11 is connected to the electrical box 12, and a controller is installed inside the control panel 11, which provides operation control. The electrical box 12 can house the electrical components that power the extrusion device 2, the hot molding device 6, the delayed curing device 7, the adjusting mechanism 4, the shaping mechanism 5, and the cutting device 8. The frame 1 is equipped with steps and guardrails. The steps provide a path for going up and down the frame 1, and the guardrails provide protection to ensure safe production.

[0070] like Figure 14As shown, in one embodiment of the present invention, a stirring tank is provided. Specifically, the stirring tank includes a tank wall 01, a tank top, and an integrally formed conical bottom 02. The tank top is connected to the top of the tank wall 01, and the integrally formed conical bottom 02 is connected to the bottom of the tank wall 01. The integrally formed conical bottom 02 is manufactured using an integrally formed stirring tank conical bottom production equipment. In this embodiment, the integrally formed conical bottom 02 is integrally formed without welds, which eliminates the safety hazard of cracking due to welds and ensures that the structural strength of the conical bottom meets the usage requirements.

[0071] Furthermore, in this embodiment, the tank wall 01 is extruded from PP or PPH material; the integrally molded tank cone bottom 02 is also extruded from PP or PPH material. Both the tank wall 01 and the integrally molded tank cone bottom 02 are integrally molded, using PP or PPH granules processed by spiral winding via extrusion. Both the tank wall 01 and the integrally molded tank cone bottom 02 are seamless, ensuring their respective structural strength. The integrally molded tank cone bottom 02 is welded to the tank wall 01 at its inner wall. During welding, the same material as the tank wall 01 and the integrally molded tank cone bottom 02 is used. After welding, the tank wall 01 and the integrally molded tank cone bottom 02 are formed as a single unit, with a strong and reliable connection. Moreover, the weld between the integrally molded tank cone bottom 02 and the tank wall 01 is located on the inner side of the tank wall 01. When the integrally molded tank cone bottom 02 is subjected to force, the weld experiences compressive force rather than tensile force, ensuring the connection strength between the integrally molded tank cone bottom 02 and the tank wall 01.

[0072] Furthermore, in this embodiment, the tank wall 01 is extruded from PPH material; the one-piece molded conical bottom 02 is extruded from PPH material; and the tank top is welded from PPH sheet. The entire tank is made of PPH material, capable of withstanding temperatures from -40℃ to 100℃, making it suitable for extremely cold and frigid conditions. This solves the global problem of existing tanks being neither resistant to low nor high temperatures. At the same time, PPH material is environmentally friendly, producing no dust or harmful substances during production and use, thus benefiting environmental protection.

[0073] like Figure 14 As shown, in one embodiment of the present invention, a wire is spirally wound inside the one-piece molded tank cone bottom 02. Preferably, the wire is aramid cord impregnated with a bonding adhesive. In this embodiment, by spirally winding the wire inside the one-piece molded tank cone bottom 02, the mechanical properties of the one-piece molded tank cone bottom 02 can be improved, and its impact resistance and deformation resistance can be enhanced. The aramid cord used has excellent material properties and can expand and contract synchronously with the one-piece molded tank cone bottom 02, thus constantly enhancing the mechanical properties. The aramid cord is impregnated with a bonding adhesive, which allows it to better bond with the molding material during the molding of the one-piece molded tank cone bottom 02.

[0074] Furthermore, in this embodiment, the wire is multi-stranded with gaps between adjacent wires, which can further enhance the mechanical properties of the integrally formed tank cone bottom 02.

[0075] like Figure 14 As shown, in one embodiment of the present invention, in order to enhance the mechanical properties of the can wall 01, a wire can be spirally wound inside the can wall 01; a strip can be spirally wound inside the can wall 01; or a combination of wire and strip can be spirally wound inside the can wall 01.

[0076] Furthermore, in this embodiment, the thread is an aramid cord impregnated with a binding adhesive. The thread is multi-stranded, with gaps between adjacent threads. The tape is an aramid fiber cloth.

[0077] like Figure 14 As shown, in one embodiment of the present invention, the inner surface of the mixing tank is coated with a corrosion-resistant layer 03, which can enhance the corrosion resistance of the mixing tank. Preferably, the thickness of the corrosion-resistant layer 03 is not less than 10 mm.

[0078] like Figure 14 As shown, in one embodiment of the present invention, the outer surface of the mixing tank is coated with an anti-ultraviolet environmental protection layer 04, which can delay the aging of the mixing tank under open-air conditions and extend its service life. Preferably, the thickness of the anti-ultraviolet environmental protection layer 04 is not less than 10mm, and the anti-ultraviolet environmental protection layer 04 is an ultraviolet environmental protection layer with a fire resistance rating of V0.

[0079] It is worth noting that in this invention, the stirring tank is a large-capacity tank, used as a container, stirring tank, etc. The wall thickness of both the tank wall 01 and the integrally formed conical bottom 02 is not less than 22mm; the diameter of the tank wall 01 is not less than 500mm.

[0080] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
