[0020] 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.
[0021] In actual production processes, due to the differences in material properties of different raw materials, the stirring structure inside traditional production reactors may not be able to fully disperse and dissipate heat from the raw materials. This situation may cause uneven temperature distribution of the raw materials inside the reactor, resulting in different reaction rates of the raw materials at different locations inside the reactor, thereby reducing the purity of the reaction products.
[0022] In view of this, the present invention provides a production reactor with uniform temperature, which solves the problem that in the actual production process, due to the differences in material properties of different raw materials, the stirring structure inside the traditional production reactor may not be able to fully disperse and dissipate heat from the raw materials. This situation may lead to uneven temperature of the raw materials inside the reactor, resulting in different reaction rates of the raw materials at different locations inside the reactor, thereby reducing the purity of the reaction products.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0024] Example 1: By Figures 1-4 It is known that a production reactor with uniform temperature includes a tank body 1, a discharge valve 11 connected to the bottom of the tank body 1, a temperature sensor 13 fixedly connected to the inner wall of the tank body 1, a sealing cover 2 fixedly connected to the top of the tank body 1, a servo motor 21 fixedly connected to the top of the sealing cover 2, a first bevel gear 22 fixedly connected to the output end of the servo motor 21, and a stirring blade 3 arranged inside the tank body 1. The production reactor with uniform temperature also includes a mixing device 4, a heating device 5, and a transmission device 6. The mixing device 4 is arranged inside the tank body 1; the heating device 5 is arranged on the outer wall of the tank body 1; and the transmission device 6 is arranged outside the mixing device 4. The mixing device 4 mixes the raw materials inside the tank body 1, the heating device 5 heats the lower temperature areas of the tank body 1, and the transmission device 6 drives the stirring blade 3 to rotate.
[0025] In the specific implementation process, it is worth noting that the tank body 1 is cylindrical in shape and can be made of stainless steel. A circular opening is provided at the top, surrounded by six threaded holes. The sealing cover 2 is fixed to the top of the tank body 1 using bolts. The sealing cover 2 can also be made of stainless steel. The discharge valve 11 at the bottom of the tank body 1 can be selected according to actual needs, as long as it meets the operational requirements. Multiple temperature sensors 13 are installed on the inner wall of the tank body 1 to monitor the temperature of the upper, middle, and lower regions inside the tank body 1. The temperature sensors 13 can be PT100 resistance temperature sensors, which operate based on the characteristic of metal resistance changing with temperature. As a passive sensor, the PT100's resistance changes with temperature, allowing temperature determination by measuring its resistance. It requires no external power source to generate a signal. However, signal processing devices paired with the PT100, such as temperature displays, data acquisition units, and wireless transmission modules, require power and can be battery-powered. The servo motor 21 is fixed to the top of the sealing cover 2 via a motor mount. The model of the servo motor 21 can be selected based on actual needs, as long as it meets operational requirements. For example, an MSMF022L1UM model motor can be selected, and the matching external controller can be an MFDLTA4NF multi-mode controller. The specific connection method for a functional servo driver is as follows: First, connect the three-phase AC power supply lines to the L1, L2, and L3 terminals of the driver's main circuit power supply, respectively. To ensure equipment safety, the driver's grounding terminal must be reliably grounded. Second, connect the positive terminal of the 24V DC power supply to the "+24V" terminal of the driver's control circuit power supply, and the negative terminal to the "0V" terminal. Next, connect the encoder cable plug to the encoder interface of the motor, ensuring the pins are firmly inserted to prevent loosening from affecting signal transmission. On the other end, according to the wiring diagram in the driver's manual, connect each core wire of the encoder cable to the encoder interface terminal of the driver, starting with the first bevel gear. Wheel 22 serves to transmit the kinetic energy of servo motor 21. The first bevel gear 22 can be made of stainless steel. Multiple stirring blades 3 are provided, consisting of mounting rings and fan blades. Multiple fan blades are fixedly connected to the outer wall of the mounting rings to stir the raw materials. The material of the fan blades can be stainless steel. The operator uses the mixing device 4 to uniformly mix the various raw materials inside the tank 1 to ensure that the temperature of the various raw materials inside the tank 1 remains uniform. The heating device 5 heats the lower temperature areas of the tank 1 from the outside to assist heating and promote the reaction. The transmission device 6 drives the stirring blades 3 to rotate, thereby achieving preliminary stirring of the raw materials.
[0026] Furthermore, the mixing device 4 includes a second bevel gear 41, a drive shaft 42, a bevel gear set 43, a drive rod 44, and a mixing blade 45. The second bevel gear 41 is meshed with the outer wall of the first bevel gear 22; the drive shaft 42 is fixedly connected to the inner wall of the second bevel gear 41 and extends into the interior of the tank 1; the bevel gear set 43 is drivenly connected to the outer wall of the drive shaft 42; the drive rod 44 is drivenly connected to the outer wall of the drive shaft 42 through the bevel gear set 43; and the mixing blade 45 is fixedly connected to the outer wall of the drive rod 44. Through the cooperation of the second bevel gear 41, the drive shaft 42, the bevel gear set 43, the drive rod 44, and the mixing blade 45, the raw materials inside the tank 1 are mixed to ensure uniform mixing of the raw materials inside the tank 1.
[0027] In the specific implementation process, it is worth noting that the tooth profile, tooth pitch, and tooth thickness of the second bevel gear 41 are the same as those of the first bevel gear 22, only the number of teeth and outer diameter are different. Both can achieve a transmission effect. The specific style can be selected according to actual needs, as long as it meets the operational requirements. Furthermore, the material of the second bevel gear 41 can be stainless steel, and the entire transmission shaft 42 is made of stainless steel. The bevel gear set 43 consists of a fourth bevel gear and a fifth bevel gear. The inner wall of the fourth bevel gear is fixed to the outer wall of the transmission shaft 42, and the outer walls of the two fifth bevel gears mesh with and connect to the two sides of the outer wall of the fourth bevel gear. All bevel gears can be made of stainless steel. There are two transmission rods 44, which can also be made of stainless steel. The two transmission rods 44 are fixedly connected to the inner walls of the two fifth bevel gears. There are multiple mixing blades 45, which can also be made of stainless steel. The blades are hexagonal plates to increase the contact area with the raw materials. The operator uses the second bevel gear 41, transmission shaft 42, bevel gear set 43, transmission rod 44 and mixing blades 45 to fully mix the raw materials inside the tank 1, ensuring that the temperature of the raw materials inside the tank 1 is uniform, thereby improving the purity of the reactants obtained through the production reactor.
[0028] Furthermore, an exhaust port 24 is provided directly in front of the second bevel gear 41, and the exhaust port 24 is connected to the top of the sealing cover 2. The side of the top of the sealing cover 2 away from the servo motor 21 is connected to the feed valve 23.
[0029] In the specific implementation process, it is worth noting that the top of the exhaust port 24 can be connected to an exhaust valve, which can discharge the gas generated during the reaction process through the exhaust port 24 to the tank 1, ensuring stable internal pressure. The feed valve 23 is used to add raw materials. Multiple feed valves 23 can be set to circulate different raw materials, preventing premature reaction between raw materials and improving the safety of the production reactor with uniform temperature.
[0030] Specifically, when it is necessary to mix and stir the raw materials inside the tank 1, the operator first puts the raw materials into the tank 1 through the feed valve 23. After the preparation is completed, the operator connects the external power supply of the servo motor 21 through the external controller and starts the servo motor 21. The servo motor 21 drives the first bevel gear 22 to rotate, the first bevel gear 22 drives the second bevel gear 41 to rotate, the second bevel gear 41 drives the transmission shaft 42 to rotate, and the transmission shaft 42 drives the two transmission rods 44 to rotate through the bevel gear set 43. The two transmission rods 44 drive the mixing blades 45 on their respective outer walls to rotate, thereby realizing the mixing and stirring of the raw materials inside the tank 1. After the reaction is completed, the reaction products leave the inside of the tank 1 through the discharge valve 11.
[0031] Example 2: From Figures 1-4 It is known that an insulation shell 12 is fixedly connected to the outer wall of the tank body 1. The insulation shell 12 has through grooves 121 on both sides of its outer wall. The heating device 5 includes an electric sliding groove 51, an electric slider 52, a power supply base 53, a fixing ring 54, and a heating wire 55. Two electric sliding grooves 51 are provided, fixedly connected to both sides of the outer wall of the insulation shell 12 and connected to one side of the through groove 121. Two electric sliders 52 are provided, slidably connected to the inner walls of the two electric sliding grooves 51. Two power supply bases 53 are provided, fixedly connected to the tops of the two electric sliders 52. The fixing ring 54 is located inside the insulation shell 12 and fixedly connected to the outer wall of the two power supply bases 53 near the end of the tank body 1. The heating wire 55 is fixedly connected to the inner wall of the fixing ring 54 and sleeved on the outer wall of the tank body 1. Through the cooperation of the electric sliding groove 51, electric slider 52, power supply base 53, fixing ring 54, and heating wire 55, the raw materials inside the tank body 1 are heated from the outside.
[0032] In the specific implementation process, it is worth noting that the insulation shell 12 can be made of alloy steel, and its interior can be filled with polystyrene foam to provide insulation for the interior of the tank 1. Through slots 121 are opened on both sides of the insulation shell 12, communicating with the outside. Two sets of electric sliding tracks 51 and electric sliders 52 are provided, working together. Their material can be aluminum alloy, and their model can be selected according to actual needs, for example, the HTS12 model. Two power supply bases 53 are provided, connected to an external power source to provide power for subsequent workpieces. Both power supply bases 53 can be connected to an external power source, or only one can be used. The power supply is connected to the power supply 53 on one side. Depending on the actual situation, the fixing ring 54 is circular in shape and has a current-carrying wire inside to transmit the power from the power supply 53. The material of the fixing ring 54 can be polyphenylene sulfide. Multiple heating wires 55 are provided. The heating wires 55 are circular in shape and are fitted on the outer wall of the tank 1. The material of the heating wires 55 can be nickel-chromium alloy. When local heating is required, the operator can heat the raw materials inside the tank 1 from the outside by using the electric slide 51, electric slider 52, power supply 53, fixing ring 54 and heating wires 55. This improves the working stability of the production reactor with uniform temperature.
[0033] Furthermore, the transmission device 6 includes a third bevel gear 61 and a stirring shaft 62. The third bevel gear 61 is located below the second bevel gear 41 and meshes with the outer wall of the first bevel gear 22, and is sleeved on the outer wall of the transmission shaft 42. The stirring shaft 62 is fixedly connected to the bottom of the third bevel gear 61, extends into the interior of the tank 1 through a sealed bearing, and is fixedly connected to the inner wall of the stirring blade 3. It is also rotatably connected to the outer wall of the transmission shaft 42 through a sealed bearing, sleeved on the outer wall of the bevel gear set 43, and rotatably connected to the outer wall of the transmission rod 44 through a sealed bearing. The stirring blade 3 is rotated by the cooperation of the third bevel gear 61 and the stirring shaft 62.
[0034] In the specific implementation process, it is worth noting that the tooth shape, tooth pitch, and tooth thickness of the third bevel gear 61 are the same as those of the first bevel gear 22, only the number of teeth and outer diameter are different. The two can achieve the transmission effect. The specific style can be selected according to actual needs to meet the work requirements. The material of the third bevel gear 61 can be stainless steel. The stirring shaft 62 is cylindrical in shape and hollow inside. The bottom is fixed with a sealing plate by anti-corrosion bolts. The sealing plate is rotatably connected to the transmission shaft 42 through a sealing bearing. The outer wall of the stirring shaft 62 is provided with multiple through holes, and a sealing bearing is fixed in the through holes to cooperate with the rotation of the transmission rod 44. A fixed truncated cone is fixedly connected to the upper part of its inner wall. The surface of the truncated cone has ventilation holes. A sealing bearing is fixed in the inner wall of the truncated cone. The fixed truncated cone supports the transmission shaft 42. The operator uses the cooperation of the third bevel gear 61 and the stirring shaft 62 to make the stirring blade 3 rotate, and the mixing blade 45 can follow the stirring blade 3 to rotate, thereby improving the stirring efficiency and achieving the reaction effect of improving the temperature uniformity of the production reactor.
[0035] Furthermore, a scraper 421 is fixedly connected to the bottom of the drive shaft 42;
[0036] In the specific implementation process, it is worth noting that the scraper 421 is in the shape of a triangular plate, which can be used to help the reaction products leave the inside of the tank 1, and can also clean the bottom of the tank 1 at the end of the reaction, thereby improving the service life of the production reactor with uniform temperature.
[0037] Specifically, when the second bevel gear 41 rotates, the third bevel gear 61 rotates following the first bevel gear 22. The third bevel gear 61 drives the stirring shaft 62 to rotate, which in turn drives the stirring blade 3 to rotate. This, in turn, drives the transmission rod 44, which is rotating vertically following the bevel gear set 43, to rotate horizontally, thus ensuring more thorough mixing of the raw materials inside the tank 1. When the temperature sensor 13 detects a significant temperature difference inside the tank 1, it transmits a signal to the external controller. The external controller then alarms, alerting the operator, who then connects the power supply 53 to an external power source. The power supply is connected to the heating wire 55 via the conductor inside the fixed ring 54 through the power supply base 53, causing the heating wire 55 to start heating. At the same time, the external controller starts the electric slide rail 51 and the electric slider 52. The electric slider 52 drives the power supply base 53 to move, the power supply base 53 drives the fixed ring 54 to move, and the fixed ring 54 drives the heating wire 55 to move until it reaches the position specified by the temperature sensor 13. The electric slider 52 stops moving, realizing the heating of that position. After the heating is completed, the electric slide rail 51 and the electric slider 52 are turned off, and the external power supply connected to the power supply base 53 is disconnected.
