Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.
[0026] As Figure 1 shown, the present application provides a rotary drum induction heating stirred tank, which comprises:
[0027] transverse shell 1;
[0028] The transverse stirring kettle device 2 is arranged in the transverse shell 1; the electromagnetic induction heating assembly 3 is arranged between the transverse stirring kettle device 2 and the transverse shell 1; one end of the transverse stirring kettle device 2 is connected with the feeding port 21, and the other end of the transverse stirring kettle 2 is connected with the discharging port 22.
[0029] Compared with the prior art, the transverse stirring kettle device 2 is arranged in the transverse shell 1; the electromagnetic induction heating assembly 3 is arranged between the transverse stirring kettle device 2 and the transverse shell 1; one end of the transverse stirring kettle device 2 is connected with the feeding port 21, and the other end of the transverse stirring kettle 2 is connected with the discharging port 22.
[0030] The transverse stirring kettle device 2 is arranged in the transverse shell 1; the electromagnetic induction heating assembly 3 is arranged between the transverse stirring kettle device 2 and the transverse shell 1; one end of the transverse stirring kettle device 2 is connected with the feeding port 21, and the other end of the transverse stirring kettle 2 is connected with the discharging port 22.
[0031] In another embodiment of the present application, as shown in Figure 1 The transverse stirring kettle device 2 includes a cylinder 23, a cylinder rotation driving assembly 24, a discharging pipe 25 and a feeding pipe 26; the cylinder rotation driving assembly 24 drives the cylinder 23 to rotate through a transmission assembly 241; the cylinder 23 is connected with the discharging port 22 through the discharging pipe 25, and the cylinder 23 is connected with the feeding port 21 through the feeding pipe 26. This design makes the transverse stirring kettle device 2 have better operability and flexibility. The cylinder 23 is driven to rotate through the transmission assembly 241, so that uniform stirring and mixing of the material can be realized.
[0032] Further, the feeding port 21 can be arranged from narrow to wide, so as to accelerate the entering speed of the material and improve the production efficiency; in addition, the arrangement of the feeding port 21 can increase the flowability of the material, so that the material can more easily enter the reaction kettle through the feeding port.
[0033] Further, the discharging port 22 can be arranged at the side of the cylinder 23, so as to facilitate the discharge of the stirred material. The feeding port 21 can be arranged at the other side of the cylinder 23, so as to facilitate the addition of the material to be stirred into the cylinder 23.
[0034] In another embodiment of the present application, as shown in Figure 1As shown, the transmission assembly 241 comprises a first gear 241a and a second gear 241b; the barrel rotation driving assembly 24 drives the first gear 241a, the first gear 241a and the second gear 241b are engaged; the second gear 241b is sleeved at the discharge pipe 25. Specifically, the barrel rotation driving assembly 24 can be an electric motor or other power source for driving the first gear 241a to rotate. When the first gear 241a rotates, it engages with the second gear 241b, thereby driving the second gear 241b to rotate. The second gear 241b can be sleeved at the right end of the barrel 23, thereby driving the barrel 23 to rotate together. This design has multiple advantages. First, the rotation of the barrel 23 is achieved through the transmission assembly 241, which can make the material inside the barrel 23 more fully stirred and mixed. Second, through the engagement of the first gear 241a and the second gear 241b, power transmission and torque amplification can be achieved, making the rotation of the barrel 23 more stable and powerful.
[0035] In another embodiment of the present application, as shown in Figure 1 The barrel 23 is provided with a fixed spiral belt 23a. By providing a fixed spiral belt 23a inside the barrel 23, the fixed spiral belt 23a does not rotate when the barrel 23 rotates, thereby stirring and mixing the material. The spiral belt 23a can be made of high-strength materials such as stainless steel or high-strength plastic to withstand harsh conditions such as high temperature, high pressure and corrosive environment.
[0036] Further, the shape and size of the fixed spiral belt 23a can be designed according to specific needs, such as spiral belts with different shapes such as threads, blades or cams, to achieve stirring and mixing effects for different materials. In addition, the fixed spiral belt 23a can stir and mix the material more carefully and uniformly, avoiding problems such as accumulation and sedimentation of the material during stirring, thereby improving the stirring effect and quality of the material. In addition, the design of the fixed spiral belt 23a can also reduce the vibration and noise of the equipment during stirring, improve the stability and reliability of the equipment.
[0037] In another embodiment of the present application, the barrel 23 can be provided with a rotating spiral belt 23, which is driven by a motor (not shown in the figure) to rotate in the opposite direction of the barrel 23, thereby further improving the stirring and mixing of the material. In addition, it is worth noting that in order to avoid the difficulty of subsequent feeding of the screw conveyor 251, the rotating speed of the rotating spiral belt 23 and the screw conveyor 251 need to maintain a certain speed difference to avoid the difficulty of taking material caused by synchronization.
[0038] In another embodiment of the present application, as shown in Figure 1As shown, the electromagnetic induction heating assembly 3 comprises a plurality of electromagnetic coils 31; all electromagnetic coils 31 are sequentially sleeved on the outer wall of the cylinder body 23 and fixed on the inner wall of the transverse shell 1, ensuring that the electromagnetic coils 31 and the outer wall of the cylinder body 23 maintain appropriate spacing to achieve effective induction heating. The electromagnetic coils 31 are all connected to the same AC generator (not shown in the figure). The plurality of electromagnetic coils 31 can heat different parts of the cylinder body 23 simultaneously or sequentially, thereby increasing the heating area and heating efficiency. At the same time, all electromagnetic coils 31 are connected to the same AC generator, which can ensure the stability and consistency of the current, avoiding problems such as uneven heating or equipment damage caused by current fluctuations or differences between different coils. Specifically, when AC passes through the electromagnetic coils 31, the electromagnetic coils 31 will generate an alternating magnetic field. This alternating magnetic field will interact with the cylinder body 23, causing the electrons in the cylinder body 23 to start moving, thereby generating an electric current, and due to the Joule effect, the cylinder body 23 generates heat energy. It should be noted that the transverse shell 1 is provided with an infrared temperature measuring instrument, and the AC generator is provided with a temperature control device, which includes a PLC temperature controller, a silicon controlled rectifier, the infrared temperature measuring instrument is electrically connected with the PLC temperature controller, and the PLC temperature controller is electrically connected with the silicon controlled rectifier. The PLC temperature controller sends a command to the silicon controlled rectifier to change the output power of the AC generator according to the signal from the infrared temperature measuring instrument, so as to achieve the purpose of temperature control.
[0039] It is worth noting that not all materials can achieve induction heating, and this method is only suitable for materials with high electrical conductivity (such as copper, gold, aluminum, etc.), so the cylinder body needs to be made of materials with high electrical conductivity; in addition, the cylinder body can also be made of ferrous metals, because the high magnetic permeability of such metals can enhance the induction eddy current and skin effect compared with other materials.
[0040] In another embodiment of the present application, as shown in Figure 1 The cylinder body 23 is provided with a plurality of radial reinforcing ribs 231 and a plurality of axial reinforcing ribs 232. First, the radial reinforcing ribs 231 and the axial reinforcing ribs 232 can increase the supporting force and bending resistance of the cylinder body 23, improve the rigidity and strength of the cylinder body 23, and enable it to withstand higher pressure and temperature; second, the radial reinforcing ribs 231 and the plurality of axial reinforcing ribs 232 inside the cylinder body 23 can increase the contact area between the cylinder body 23 and the reaction material, improve the heat transfer efficiency, and accelerate the reaction speed; finally, the arrangement of the radial reinforcing ribs 231 and the plurality of axial reinforcing ribs 232 can reduce the impact and wear of the material on the cylinder body 23, enhance the corrosion resistance of the cylinder body 23, and prolong the service life of the cylinder body 23.
[0041] In another embodiment of the present application, as shown in Figure 1As shown, the feed pipe 26 is also connected with a pressure relief smoke outlet 261. The setting of the pressure relief smoke outlet 261 can realize the discharge of the internal pressure and smoke of the cylinder 23. During the operation of the cylinder 23, due to the chemical reaction and heating process of the material, a certain pressure and smoke may be generated in the cylinder 23. If these pressure and smoke are not discharged in time, it may affect the sealing and safety of the cylinder 23, and even cause an accident.
[0042] By setting the pressure relief smoke outlet 261, the pressure and smoke in the cylinder 23 can be discharged in time, ensuring the safety and stability of the cylinder 23. At the same time, the design of the pressure relief smoke outlet 261 can also reduce the noise and vibration of the equipment during operation, improve the comfort and reliability of the equipment.
[0043] In another embodiment of the present application, as shown in Figure 1 The spiral conveyor 251 in the discharge pipe 25 forms a spiral channel, which prolongs the flow path of the condensed water, thereby prolonging the condensation time of the condensed water and improving the cooling effect on the high-temperature material.
[0044] In order to further improve the high-temperature resistance of the spiral conveyor 251, the drive of the spiral conveyor 251 can be separated from the main machine, and chain transmission is adopted for transmission to reduce heat transfer. In addition, the material of the spiral conveyor 252 is usually selected from high-temperature resistant and corrosion resistant metals or plastics, such as stainless steel, special steel, ceramics, etc. Finally, the bearing and sealing design of the spiral conveyor 252 can prevent the damage of high-temperature material to the bearing and sealing element, for example, using high-temperature resistant bearing, and spacing the bearing seat from the main machine of the conveyor.
[0045] In another embodiment of the present application, as shown in Figure 1 Each bearing 233 is arranged in the opening at the two ends of the lateral shell 1 on the same side. This kind of setting form of the bearing 233, i.e. arranging the bearing 233 at the two ends of the cylinder 23, can realize the stable support and guidance of the cylinder 23, avoiding the problems such as shaking or tilting of the cylinder 23 during operation.
[0046] In another embodiment of the present application, as shown in Figure 1 A layer of fireproof and heat insulation layer 10 is arranged in the lateral shell 1. The fireproof and heat insulation layer 10 is a kind of material that can effectively insulate high temperature and heat conduction, which is usually composed of high-temperature resistant materials such as refractory fiber, refractory brick, ceramic fiber, etc. By arranging the fireproof and heat insulation layer 10 in the lateral shell 1, the high temperature influence on the cylinder 23 can be reduced, and the deformation or damage of the cylinder 23 due to high temperature can be avoided. At the same time, the fireproof and heat insulation layer 1 can also effectively reduce heat conduction, improve the thermal efficiency and service life of the equipment.
