Description

Technical Field

[0001] This utility model relates to the technical field of dibromobiphenyl production equipment, specifically a double cone dryer for chemical product production. Background Technology

[0002] Dibromobiphenyl is an organic compound and an important intermediate in organic synthesis. It is widely used in the synthesis of various organic compounds, including those important in pesticides, pharmaceuticals, and materials science. A double-cone dryer for chemical product manufacturing is a drying device used to dry dibromobiphenyl. It achieves uniform drying of dibromobiphenyl by rotating a double-cone-shaped processing tank and utilizing hot air. In the existing technology: Authorization Publication No. CN 222635031 U's patent discloses a double cone dryer for chemical product production, including a frame and a double cone dryer shell. The double cone dryer shell has a feed end plate at the top and a discharge end plate at the bottom. Inside the double cone dryer shell, there is a partition plate between the feed end plate and the discharge end plate. The feed end plate has a first feed port and a second feed port on both sides of the partition plate. The discharge end plate has a first discharge port and a second discharge port on both sides of the partition plate. A feed sealing plate is installed outside the feed end plate. Although this equipment can dry two different materials through two sets of drying chambers during use, when some materials have a high initial moisture content, some of the materials with high moisture content will clump together. The clumps cannot be heated evenly during the drying process, and the internal moisture is difficult to evaporate, resulting in insufficient drying of some materials and affecting the drying effect. Therefore, we propose a double cone dryer for chemical product production. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-8 This embodiment provides a technical solution: a double cone dryer for chemical product production, including a base 1, a processing tank 3 on the upper side of the base 1, a feed pipe 4 in the feed inlet at the middle of the upper end of the processing tank 3, a feed valve connected in series in the middle of the feed pipe 4, a discharge pipe 5 in the discharge inlet at the middle of the lower end of the processing tank 3, a discharge valve connected in series in the middle of the discharge pipe 5, a heating chamber 6 inside the processing tank 3, and a mixing mechanism 8; Mixing mechanism 8: It includes a cavity 81, an internal gear ring 83, a gear 84, and a stirring blade 85. The cavity 81 is located on the left side inside the base 1. The internal gear ring 83 is installed inside the cavity 81, and the gear 84 is installed inside the cavity 81. The gear 84 meshes with the internal gear ring 83. The stirring blade 85 is installed inside the processing tank 3. The mixing mechanism 8 also includes a crossbar 82 and a protective plate 86. The protective plate 86 is rotatably connected to the right side inside the cavity 81. The lower side of the right end of the protective plate 86 is rotatably connected to the crossbar 82. The left end of the crossbar 82 is equipped with the gear 84, and the right end of the crossbar 82 is rotatably connected to the clearance groove opened on the left side of the outer arc surface of the processing tank 3. The right side of the outer arc surface of the crossbar 82 is equipped with stirring blades 85. During the rotation of the processing tank 3, the processing tank 3 will drive the crossbar 82 to rotate around the connecting component on the left side. The crossbar 82 will drive the gear. Gear 84 rotates around the connecting assembly on the left. During the rotation of gear 84, gear 84 revolves around the inner gear ring 83, causing the crossbar 82 to rotate while driving the stirring blade 85 to rotate. The stirring blade 85 stirs the dibromobiphenyl and breaks up some of the clumps of dibromobiphenyl. Since the teeth of gear 84 are smaller than those of the inner gear ring 83, the rotational speed of crossbar 82 is greater than that of processing tank 3. The high-speed crossbar 82 can more effectively break up the material and improve drying efficiency. During the rotation of crossbar 82, it can drive the stirring blade 84 to rotate, which can break up dibromobiphenyl, prevent dibromobiphenyl from accumulating inside processing tank 3, increase the contact area between dibromobiphenyl and the inner wall of processing tank 3, promote heat transfer, and further improve the drying efficiency of dibromobiphenyl.

[0016] Among them, the right end of the base 1 is equipped with a controller 2. The input end of the controller 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0017] The upper side of the interior of the base 1 is rotatably connected to a connecting pipe 9. A cavity 81 is located outside the left connecting pipe 9. A processing tank 3 is positioned between the opposing inner surfaces of the two connecting pipes 9. The opposing inner ends of the two connecting pipes 9 are connected to the connecting groove inside the heating chamber 6. An air inlet pipe 10 is installed in the air inlet on the upper side of the left end of the base 1. An air inlet valve is connected in series on the left side of the air inlet pipe 10. An exhaust pipe 11 is installed in the exhaust outlet on the upper side of the right end of the base 1. An exhaust valve is connected in series on the right side of the exhaust pipe 11. The right end of the air pipe 10 is rotatably connected to the left end of the left connecting pipe 9, and the left end of the exhaust pipe 11 is rotatably connected to the right end of the right connecting pipe 9. The hot air generated by the external hot air blower will enter the interior of the air inlet pipe 10 through the external pipe. Then the hot air inside the air inlet pipe 10 will enter the interior of the heating chamber 6 through the left connecting pipe 9. After that, the hot air will heat the dibromobiphenyl inside the processing tank 3 through the inner wall of the heating chamber 6. The hot air after use will enter the interior of the exhaust pipe 11 through the right connecting pipe 9 and be discharged.

[0018] Temperature detectors 12 are installed on the upper side of the outer arc surface of both the intake pipe 10 and the exhaust pipe 11. The left-side temperature detectors 12 are located between the left end of the base 1 and the right end of the intake valve, while the right-side temperature detectors 12 are located between the right end of the base 1 and the left end of the exhaust valve. The probes at the lower ends of the temperature detectors 12 are located inside the intake pipe 10 and the exhaust pipe 11, respectively. Both temperature detectors 12 are bidirectionally electrically connected to the controller 2. The two sets of temperature detectors 12 collect temperature signals from inside the intake pipe 10 and the exhaust pipe 11 respectively through resistance temperature sensors. The resistance temperature sensors convert temperature changes into changes in resistance values, and then the temperature detectors 12 transmit these signals through internal... The algorithm converts the resistance value into a temperature value. Then, the data calculated by the temperature detector 12 is transmitted to the controller 2 through the built-in data transmission component. The controller 2 receives the detected data through the built-in serial communication port. By measuring the temperature difference between the air inlet pipe 10 and the exhaust pipe 11, the temperature change inside the processing tank 3 can be inferred. If the temperature of the air inlet pipe 10 is higher than that of the exhaust pipe 11, it means that the dibromobiphenyl in the tank has absorbed some heat, causing the temperature of the exhaust pipe 11 to decrease. If the temperature difference increases, it means that the drying effect is good and the current parameters can be maintained. If the temperature difference decreases, it means that the drying effect is poor and the heating parameters need to be adjusted, such as increasing the temperature of the hot air.

[0019] The base 1 has a fixed plate 13 on the right side, a servo motor 15 on the front side of the upper end of the fixed plate 13, a worm gear 16 on the upper end of the output shaft of the servo motor 15, and a worm wheel 14 in the middle of the outer arc surface of the connecting pipe 9 on the right side. The worm wheel 14 is meshed with the worm gear 16. The input end of the servo motor 15 is electrically connected to the output end of the controller 2. During the heating of dibromobiphenyl, the servo motor 15 starts to run through the control of the controller 2. The output shaft of the servo motor 15 drives the worm gear 16 to rotate. During the rotation of the worm gear 16, it drives the worm wheel 14 to rotate through the meshing connection. During the rotation of the worm wheel 14, it drives the processing tank 3 to rotate through the connecting pipe 9 on the right side.

[0020] The system also includes an exhaust pipe 7, which is installed in an installation groove on the upper side of the outer arc surface of the discharge pipe 11. The left end of the exhaust pipe 7 is rotatably connected to the exhaust hole on the right side of the inner arc surface of the processing tank 3. The exhaust pipe 7 is located between the right end of the base 1 and the left end of the temperature detector 12 on the right side. An exhaust valve is connected in series on the upper side of the exhaust pipe 7. When the exhaust valve is opened, the gas generated by dibromobiphenyl during the heating process will be discharged through the exhaust pipe 7.

[0021] The working principle of the double cone dryer for chemical product production provided by this utility model is as follows: Before use, connect the exhaust pipe 7, inlet pipe 10, and outlet pipe 11 to the external pipeline (the flange one on the outside of the exhaust pipe 7, inlet pipe 10, and outlet pipe 11 is connected to the flange two on the external pipeline by screws). Then, open the feed valve and add the dibromobiphenyl to be dried into the processing tank 3 through the feed pipe 4. Since the capacity of the processing tank 3 is fixed, the operator needs to record the amount of various dibromobiphenyls added during the process of adding them. The operator then uses the records to determine the remaining space inside the processing tank 3. After adding enough dibromobiphenyl, the operator closes the feed valve and then opens the inlet valve, outlet valve, and exhaust valve. The valve allows hot air generated by an external hot air blower to enter the intake pipe 10 through an external pipe. The hot air inside the intake pipe 10 then enters the heating chamber 6 through the left connecting pipe 9. The hot air then heats the dibromobiphenyl inside the processing tank 3 by passing through the inner wall of the heating chamber 6. After use, the hot air enters the exhaust pipe 11 through the right connecting pipe 9 and is discharged. The gas generated during the heating process of dibromobiphenyl is discharged through the exhaust pipe 7. Two sets of temperature detectors 12 collect temperature signals from the intake pipe 10 and the exhaust pipe 11 respectively using resistance temperature detectors (RTDs). The RTDs convert temperature changes into resistance changes, and the temperature detectors 12 then convert the resistance values ​​into temperature values ​​using a built-in algorithm. The data calculated by the temperature detector 12 is transmitted to the controller 2 via the built-in data transmission component. The controller 2 receives the detected data through its built-in serial communication port. By measuring the temperature difference between the inlet pipe 10 and the outlet pipe 11, the temperature change inside the processing tank 3 can be inferred. If the temperature of the inlet pipe 10 is higher than that of the outlet pipe 11, it indicates that the dibromobiphenyl inside the tank has absorbed some heat, causing the temperature of the outlet pipe 11 to decrease. If the temperature difference increases, it indicates that the drying effect is good and the current parameters can be maintained. If the temperature difference decreases, it indicates that the drying effect is poor and the heating parameters need to be adjusted, such as increasing the temperature of the hot air. During the heating process of dibromobiphenyl, the servo motor 15 starts running under the control of the controller 2. The output of the servo motor 15... The shaft drives the worm gear 16 to rotate. During the rotation of the worm gear 16, it drives the worm wheel 14 to rotate through the meshing connection. During the rotation of the worm wheel 14, it drives the processing tank 3 to rotate through the connecting pipe 9 on the right side. When the processing tank 3 rotates, dibromobiphenyl will continuously tumble inside the processing tank 3, which helps to mix the dibromobiphenyl evenly and ensures that each part is heated evenly. During the rotation of the processing tank 3, the processing tank 3 will drive the crossbar 82 to rotate around the connecting pipe 9 on the left side. The crossbar 82 will drive the gear 84 to rotate around the connecting pipe 9 on the left side. During the rotation of the gear 84, the gear 84 will revolve around the inner gear ring 83 (the central axis of the inner gear ring 83 is the same as that of the connecting pipe 9 on the left side).This allows the crossbar 82 to rotate while simultaneously driving the stirring blades 85 to rotate. During the turbulence of dibromobiphenyl, the stirring blades 85 disperse the dibromobiphenyl. Because the teeth of gear 84 are smaller than those of the internal gear ring 83, the crossbar 82 rotates at a higher speed than the processing tank 3. The high-speed crossbar 82 can more effectively disperse the material, improving drying efficiency. The drying time is typically adjusted based on the initial moisture content of the dibromobiphenyl. The operator can use an external timing device (mobile phone or timer) to keep track of the time. After the specified mixing time is reached, the controller 2 controls the discharge pipe 5 to rotate to the lower side of the base 1, at which point the servo motor 15 stops. The collection device is then placed under the discharge pipe 5, the discharge valve is opened, and the dried dibromobiphenyl is discharged through the discharge pipe 5. It is worth noting that the controller 2 disclosed in the above embodiments can be AT89C51, the temperature detector 12 can be OHR-E700, and the servo motor 15 can be ECMA-C20604RS. The controller 2 controls the operation of the temperature detector 12 and the servo motor 15 using methods commonly used in the prior art.
