Description

Technical Field

[0001] This disclosure relates to the field of heating and stirring devices, and in particular to the structure of a steam-heated stirring tank for heating quenching oil raw materials. Background Technology

[0002] When making quenching oil, stirring and blending are required. Due to the low temperature in winter, the additives are difficult to dissolve in the raw materials during stirring, which leads to a longer stirring time for the quenching oil raw materials and affects the efficiency of stirring the quenching oil raw materials.

[0003] When making quenching oil, stirring and blending are required. Due to the low temperature in winter, additives are difficult to dissolve in the raw materials during stirring, so the raw materials need to be heated. In existing technology, to avoid heat loss and improve heating efficiency, a partition is usually added to the outside of the mixing tank, and a heat source is input into the partition to heat the inside of the tank. In this process, due to the distance between the center of the tank and the inner wall of the tube, the heating is uneven between the center and the edge, which is difficult to solve with conventional heat transfer methods.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] In this invention, each stirring assembly is separated by a fixed plate and a rotating plate. During stirring, the rotating plate is driven by the central shaft to rotate to the bottom of the fixed plate, opening the notch to facilitate the flow of oil into the first stirring tank. Then the rotating plate returns to its original position, dividing the oil into three layers. By reducing the oil content, the overall heating efficiency is improved. The heat from the annular tube is sent into the fixed plate through the connecting groove, and then flows through the hollow tube, horizontal tube, and vertical tube before being sent out. In this process, in conjunction with the heating of the inside of the first stirring tank by the annular tube, the fixed plate and horizontal tube structures can heat the oil from the inside, thereby improving the heating efficiency and the uniformity of heating.

[0018] This invention uses a second motor to drive a drive gear to rotate and mesh with a gear ring. Through the connection of the connecting frame, the shaft disk and the rotating disk rotate synchronously. The stirring rack inside the second stirring tank rotates together with the rotating disk to stir and preheat the oil inside the second stirring tank. Two adding pipes are installed on the top of the second stirring tank for adding oil and additives. A solenoid valve is installed inside the conveying pipe to send the oil into the first stirring tank after preheating to complete the heating and stirring. The gear ring is fixedly connected to the annular tube, so the rotation of the gear ring can drive the rotation of the annular tube. Different positions of the annular tube correspond to the positions of the air inlet box and the air outlet box, so that the inside of the annular tube is heated evenly and there will be no temperature difference due to the flow. Furthermore, because of the connection between the annular tube and the rotating ring, it also drives the stirring components inside the first stirring tank to rotate.

[0019] During feeding and mixing, the first motor drives the baffle to rotate via the fixed frame, blocking the position of the rotating plate to prevent oil from flowing out. At this time, the telescopic tube extends and the plug blocks the outlet pipe. After the mixing and heating are completed, the first motor opens the baffle. With the rotation of the rotating plate, the oil can flow out through the notch of the moving plate. As the first motor drives in the reverse direction, the screw in the telescopic tube drives the plug to move upward, opening the outlet pipe and facilitating the delivery of the oil.

[0020] In this invention, after the air supply box sends the still-warm air into the air exchange box, it enters the serpentine tube from the bottom through the air hole and the first connecting pipe. After heat exchange with the second mixing tank through the serpentine tube, it is sent out through the second connecting pipe at the top and then through the exhaust pipe. As the drive gear of the drive assembly rotates, the first bevel gear meshes with the second bevel gear, thereby driving the partition frame to rotate. The chambers connected by the first and second connecting pipes alternately change. The hot air changes from entering the second connecting pipe from the first connecting pipe and being sent out to entering the first connecting pipe from the second connecting pipe, thus changing the direction of air flow inside the serpentine tube. This keeps the head and tail ends of the serpentine tube at similar temperatures during heat exchange and air flow, avoiding temperature differences that could affect heat exchange and the preheating effect on the second mixing tank.

[0021] This invention improves the heating efficiency of quenching oil by preheating the second mixing tank and heating the first mixing tank. The cooperation of the drive component, heat transfer component and stirring component divides the interior of the first mixing tank into three groups, and heats and stirs the oil in batches, which makes the temperature conduction more uniform and the mixing efficiency higher. The inlet and outlet gas components can recover hot steam for preheating, avoiding waste of resources.

[0043] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the embodiment of this disclosure, a steam-heated stirring tank structure for heating quenching oil raw materials is proposed, comprising: a first stirring tank 1, a first insulation layer 11 fixed to the outside of the first stirring tank 1, and multiple sets of heat transfer components 18 stacked and fixed inside the first insulation layer 11; a second stirring tank 2 fixed to the top of the first stirring tank 1, and a second insulation layer 22 fixed to the outside of the second stirring tank 2, a serpentine tube 25 fixed inside the second insulation layer 22; three sets of stirring components 5 equidistantly installed inside the first stirring tank 1; and a drive component provided on the top of the first stirring tank 1. 3. An air inlet / outlet assembly 4 is provided on the outer side of the second insulation layer 22, and the air inlet / outlet assembly 4 is connected to the air inlet end and air outlet end of the serpentine tube 25; the heat transfer assembly 18 includes an annular tube 181, and connecting rings 182 are rotatably installed on the top and bottom of the annular tube 181, and a collar 183 is fixed on the outer ring of the annular tube 181; the stirring assembly 5 includes a rotating ring 51, and three sets of rotating rings 51 are provided. The three sets of rotating rings 51 are equidistantly rotatably installed inside the first stirring tank 1, and the rotating rings 51 are fixedly connected to the corresponding annular tubes 181. A fixed disk 52 is provided at the center, and fixed plates 54 are fixed at both ends of the fixed disk 52. The outer side of the fixed plate 54 is fixedly connected to the rotating ring 51. A hollow tube 56 is fixed at the top of the fixed disk 52, and three sets of horizontal tubes 57 are fixed at equal intervals on both sides of the hollow tube 56. The air inlet / outlet assembly 4 includes an air exchange box 41, which is fixed to the outside of the second insulation layer 22. A partition frame 48 is rotatably installed inside the air exchange box 41, and the partition frame 48 divides the interior of the air exchange box 41 into four spaces. The drive assembly 3 includes a rotating disk 33, which rotates. Installed at the bottom of the second mixing tank 2, and rotatably mounted on the top of the first mixing tank 1, the toothed ring 31 is fixedly connected to the rotating disk 33. When using the device, the heating efficiency of the quenching oil can be improved by preheating the second mixing tank 2 and heating the first mixing tank 1. The drive component 3, in cooperation with the heat transfer component 18 and the stirring component 5, divides the interior of the first mixing tank 1 into three groups, and heats and stirs the oil in batches, which can make the temperature conduction more uniform and the mixing efficiency higher. The inlet and outlet air component 4 can recover the hot steam for preheating, avoiding waste of resources.

[0045] like Figure 1 , Figure 5 and Figure 7As shown, in some embodiments, the first insulation layer 11 is fixed to an air supply box 16 on one side of the bottom of the air exchange box 41, and an air inlet box 13 is fixed to the other side of the first insulation layer 11. The air inlet box 13 and the air supply box 16 are fixedly connected to each collar 183 through pipes. A steam generator 12 is fixed to the outside of the air inlet box 13, and one end of the steam generator 12 is connected to the inside of the air inlet box 13. A drain pipe 17 is fixed to the surface of the first insulation layer 11 between the air inlet box 13 and the air supply box 16, and the drain pipe 17 is fixedly connected to the connecting ring 182 at the bottom of each annular pipe 181 through branch pipes.

[0046] It is understandable that hot steam is sent into the air inlet box 13 through the steam generator 12, and then into the annular pipe 181 through the non-rotating collar 183. It is then transferred to the first stirring tank 1. During the rotation of the annular pipe 181, the positions of the air inlet and outlet ends corresponding to the annular pipe 181 can be changed, thereby maintaining the temperature balance inside the annular pipe 181. The air with residual heat is sent into the air exchange box 41 through the air delivery box 16, thereby recovering and reusing the heat source.

[0047] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the stirring assembly 5 further includes: a base 53, a rotating plate 55, a scraper 58, and a vertical tube 59. The base 53 is rotatably connected to the bottom of the fixed plate 52. The rotating plate 55 is fixed to the base 53 at the position of the notch between the two fixed plates 54, and both the rotating plate 55 and the fixed plate 54 are quarter-circular plates. The scraper 58 is fixed to the end of the horizontal tube 57 away from the hollow tube 56, and the scraper 58 slides in contact with the outer wall of the first stirring tank 1. The outermost ends of the three sets of horizontal tubes 57 are fixed with vertical tubes 59, and the bottom of the vertical tube 59 is... The fixed plate 54 is fixedly connected to the fixed plate 54; wherein, the top of the fixed plate 54 is slidably connected to the cleaning plate 510, and the cleaning plate 510 is fixedly connected to the chassis 53 through the arc frame. The fixed plate 54, the fixed disk 52, the hollow tube 56, the horizontal tube 57 and the vertical tube 59 are all hollow inside. The rotating ring 51 has a connecting groove 110 at the hollow position of the fixed plate 54, and the connecting groove 110 is connected to the interior of the corresponding annular tube 181. The hollow tube 56 has a central shaft 19 rotatably installed at the axis, and the central shaft 19 is fixedly connected to the chassis 53.

[0048] Understandably, each stirring assembly 5 is separated by a fixed plate 54 and a rotating plate 55. During stirring, the central shaft 19 drives the rotating plate 55 to rotate to the bottom of the fixed plate 54, opening the notch to facilitate the flow of oil into the first stirring tank 1. Then, the rotating plate 55 returns to its original position, dividing the oil into three layers. By reducing the oil content, the overall heating efficiency is improved. The heat from the annular pipe 181 is sent into the fixed plate 54 through the connecting groove 110, and then flows through the hollow pipe 56, horizontal pipe 57, and vertical pipe 59 before being discharged. In this process, in conjunction with the heating of the inside of the first stirring tank 1 by the annular pipe 181, the fixed plate 54 and horizontal pipe 57 and other structures can heat the oil from the inside, thereby improving the heating efficiency and the uniformity of heating.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, a shaft disk 14 is rotatably mounted on the top of the first mixing tank 1, and a central shaft 19 rotatably extends out of the shaft disk 14. Three sets of connecting frames 32 are fixed at equal intervals on the outer edge of the shaft disk 14, and the connecting frames 32 are fixedly connected to the gear ring 31. A horizontal plate 117 is fixed to the top of the central shaft 19, and an electric push rod 118 is rotatably connected to one side of the top of the shaft disk 14 via a rotating shaft. The extended end of the electric push rod 118 is rotatably connected to the horizontal plate 117 via a rotating shaft. The drive assembly 3 further includes a second motor 34 and a drive gear 35. The second motor 34 is fixed to the outer side of the top of the air supply box 16, and a drive gear 35 is fixed to the output end of the second motor 34. The drive gear 35 meshes with the gear ring 31. A first bevel gear 46 is fixed to the top of the shaft of the moving gear 35 via a vertical shaft. A second bevel gear 47 is fixed to the shaft of the partition frame 48 through the ventilation box 41. The first bevel gear 46 and the second bevel gear 47 are meshed and connected. A stirring frame 23 is rotatably installed inside the second stirring tank 2. The bottom of the stirring frame 23 is fixed to the rotating disk 33. A stirring plate is provided at the upper end of the stirring frame 23, and three sets of stirring blades are fixed at the lower end of the stirring frame 23 via a welded inclined frame. A conveying pipe 24 is fixed to the bottom of the rotating disk 33, and the bottom of the conveying pipe 24 is fixedly connected to the shaft disk 14. The horizontal plate 117 is rotated by the electric push rod 118, and the central shaft 19 also rotates, which can open the notch of each set of stirring components 5 and close it during stirring.

[0050] It should be noted that the second motor 34 drives the drive gear 35 to rotate and mesh with the gear ring 31. Through the connection of the connecting frame 32, the shaft disk 14 and the rotating disk 33 rotate synchronously. The stirring rack 23 inside the second stirring tank 2 rotates together with the rotating disk 33, stirring and preheating the oil inside the second stirring tank 2. Two addition pipes 21 are installed on the top of the second stirring tank 2 for adding oil and additives. A solenoid valve is installed inside the delivery pipe 24, which can send the oil into the first stirring tank 1 after preheating to complete the heating and stirring. The gear ring 31 is fixedly connected to the annular pipe 181. Furthermore, the rotation of the gear ring 31 can drive the rotation of the annular tube 181, aligning different positions of the annular tube 181 with the positions of the air inlet box and the air outlet box, thereby ensuring uniform heating inside the annular tube 181 and preventing temperature differences caused by the flow. In addition, due to the connection between the annular tube 181 and the rotating ring 51, it will also drive the rotation of the stirring assembly 5 inside the first stirring tank 1. The stirring frame 23 is divided into an upper stirring part and a lower stirring blade part. The stirring blade is fixed to the blade by a inclined frame and a pressure plate welded to the rotating disk 33, thereby ensuring the consistency of the stirring angle and preventing the blade from thermally deforming during welding.

[0051] like Figure 10 As shown, in some embodiments, an outlet pipe 15 is fixed to the bottom of the first mixing tank 1, and a plug 116 is slidably and sealed inside the outlet pipe 15. A mounting plate 111 is fixed to the bottom of the first mixing tank 1 near the bottom of the lowest mixing assembly 5, and a first motor 113 is fixed to the axis of the mounting plate 111. A fixing frame 114 is fixed to the output end of the first motor 113, and baffles 112 are fixed to both ends of the fixing frame 114. The mounting plate 111 corresponds to the position of the fixing plate 54, and the baffles 112 correspond to the position of the rotating plate 55. A telescopic tube 115 is fixed to the fixing frame 114, and the extended end of the telescopic tube 115 is fixedly connected to the plug 116. A screw is rotatably installed inside the telescopic tube 115, and the top of the screw inside the telescopic tube 115 is fixedly connected to the output end of the first motor 113. The plug 116 is threaded onto the bottom of the screw.

[0052] It should be noted that during feeding and stirring, the first motor 113 drives the baffle 112 to rotate through the fixed frame 114, blocking the position of the rotating plate 55 to prevent oil from flowing out. At this time, the telescopic tube 115 extends, and the plug 116 blocks the outlet pipe 15. After stirring and heating are completed, the first motor 113 opens the baffle 112. After the rotating plate 55 rotates, the oil can flow out through the notch of the moving plate. With the reverse drive of the first motor 113, the screw in the telescopic tube 115 drives the plug 116 to move upward, opening the outlet pipe 15 to facilitate the delivery of oil.

[0053] like Figure 6 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the air inlet / outlet assembly 4 further includes: an air supply pipe 42, a first connecting pipe 43, a second connecting pipe 44, an exhaust pipe 45, a partition frame 48, and air holes 49. Sealing discs are fixed on both sides of the partition frame 48. Air holes 49 are opened on the outer side of the sealing discs of the partition frame 48 corresponding to the positions of the four chambers. Exhaust pipes 45 are fixed to two of the air holes 49 on the sealing discs of the partition. The second connecting pipe 44 is fixed to the top of the serpentine tube 25, and the first connecting pipe 43 is fixed to the bottom of the serpentine tube 25. The first connecting pipe 43 and the second connecting pipe 44 communicate with two adjacent chambers of the partition frame 48. An air supply pipe 42 is fixed to the top of the air supply box 16, and the air supply pipe 42 communicates with the space outside the sealing disc inside the air exchange box 41.

[0054] It should be noted that the two ends of the serpentine tube 25 are connected to the first connecting pipe 43 and the second connecting pipe 44, and the first connecting pipe 43 and the second connecting pipe 44 are respectively connected to the two adjacent partition frame 48 chambers. The chambers connected to the first connecting pipe 43 and the second connecting pipe 44 correspond to the positions of the air hole 49 and the exhaust pipe 45, respectively. After the air supply box 16 sends the still warm air into the air exchange box 41, it enters the serpentine tube 25 from the bottom through the air hole 49 and the first connecting pipe 43. After heat exchange with the second stirring tank 2 through the serpentine tube 25, it is sent out through the second connecting pipe 44 at the top and then through the exhaust pipe 45. The exhaust is then sent out through the drive gear 3 of the drive assembly 3. With rotation 5, the first bevel gear 46 meshes with the second bevel gear 47, thereby driving the partition frame 48 to rotate. The chambers connected by the first connecting pipe 43 and the second connecting pipe 44 alternately change. Hot air enters from the first connecting pipe 43 and exits from the second connecting pipe 44, and then enters from the second connecting pipe 44 and exits from the first connecting pipe 43. This changes the direction of airflow inside the serpentine tube 25, thereby keeping the head and tail ends of the serpentine tube 25 at similar temperatures during heat exchange and airflow. This avoids temperature differences affecting heat exchange and the preheating effect inside the second mixing tank 2. Fans are installed inside the exhaust pipe 45 and the air supply pipe 42 to guide the airflow.

[0055] Working principle:

[0056] In operation, hot steam is fed into the air inlet box 13 via the steam generator 12, and then enters the annular tube 181 through the stationary collar 183. It is then transferred to the first mixing tank 1. During the rotation of the annular tube 181, the positions of the air inlet and outlet relative to the annular tube 181 can be changed, thereby maintaining a balanced temperature inside the annular tube 181. Air with residual heat is then supplied to the air exchange box 41 via the air delivery box 16. Each mixing assembly 5 is separated by a fixed plate 54 and a rotating plate 55. During mixing, the central shaft... 19 drives the rotating plate 55 to rotate to the bottom of the fixed plate 54, opening the notch to facilitate the flow of oil into the first mixing tank 1. Then, the rotating plate 55 returns to its original position, dividing the oil into three layers. By reducing the oil content, the overall heating efficiency is improved. The heat from the annular pipe 181 is sent into the fixed plate 54 through the connecting groove 110, and flows through the hollow pipe 56, horizontal pipe 57, and vertical pipe 59 before finally exiting. During this process, in conjunction with the heating of the first mixing tank 1 by the annular pipe 181, the fixed plate 54... The structure, including the horizontal tube 57, allows for internal heating of the oil, thereby improving heating efficiency and uniformity. The second motor 34 drives the drive gear 35 to rotate and mesh with the gear ring 31. Through the connection of the connecting frame 32, the shaft disk 14 and the rotating disk 33 rotate synchronously. The stirring rack 23 inside the second stirring tank 2 rotates together with the rotating disk 33 to stir and preheat the oil inside the second stirring tank 2. Two adding pipes 21 are installed on the top of the second stirring tank 2 for adding oil and additives. The conveying pipe 24 is equipped with a solenoid valve, which can send the oil into the first stirring tank 1 after preheating to complete heating and stirring. The gear ring 31 is fixedly connected to the annular tube 181, so the rotation of the gear ring 31 can drive the annular tube 181 to rotate. Different positions of the annular tube 181 correspond to the positions of the air inlet box and the air outlet box, thereby making the internal heating of the annular tube 181 uniform and preventing temperature differences due to flow. Furthermore, because the annular tube 181 is connected to the rotating ring 51, it also drives the stirring assembly 5 inside the first stirring tank 1 to rotate.The mixing frame 23 is divided into an upper mixing section and a lower mixing blade section. The mixing blade is fixed to the blade by a inclined frame welded to the rotating disk 33 and a pressure plate, thereby ensuring the consistency of the mixing angle and preventing the blade from thermally deforming during welding. During feeding and mixing, the first motor 113 drives the baffle 112 to rotate through the fixing frame 114, sealing the position of the rotating plate 55 to prevent oil from flowing out. At this time, the telescopic pipe 115 extends, and the plug 116 seals the outlet pipe 15. After the mixing and heating are completed, the first motor 113... 13. When the baffle 112 is opened, and the rotating plate 55 rotates, the oil can flow out through the notch of the moving plate. With the reverse drive of the first motor 113, the screw in the telescopic tube 115 drives the plug 116 to move upward, opening the outlet pipe 15 to facilitate the delivery of oil. The two ends of the serpentine tube 25 are connected to the first connecting pipe 43 and the second connecting pipe 44, and the first connecting pipe 43 and the second connecting pipe 44 are respectively connected to the two adjacent partition frame 48 chambers. The chambers correspond to the positions of the air vent 49 and the exhaust pipe 45, respectively. After the air supply box 16 sends the still-warm air into the air exchange box 41, it enters the serpentine tube 25 from the bottom through the air vent 49 and the first connecting pipe 43. After heat exchange with the second mixing tank 2 through the serpentine tube 25, it is discharged through the second connecting pipe 44 at the top and then through the exhaust pipe 45. As the drive gear 35 of the drive assembly 3 rotates, the first bevel gear 46 meshes with the second bevel gear 47, thereby driving the partition frame 48 to rotate. The first connecting pipe 43 and... The chambers connected by the second connecting pipe 44 alternately change direction. Hot air enters from the first connecting pipe 43 and exits through the second connecting pipe 44, then enters from the second connecting pipe 44 and exits through the first connecting pipe 43. This alters the direction of airflow inside the serpentine tube 25, ensuring that the head and tail ends of the serpentine tube 25 maintain similar temperatures during heat exchange and airflow. This prevents temperature differences from affecting heat exchange and preheating the second mixing tank 2. Fans are installed inside the exhaust pipe 45 and the air supply pipe 42 to guide the airflow.
