DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0019] Please refer to Figure 1 - Figure 3This utility model provides an embodiment of a heating device for surfactant production, comprising a support leg 1, a heating tank 2 fixedly connected to the top surface of the support leg 1, a feeding hopper 3 fixedly connected to the top surface of the heating tank 2, an observation port 4 on the surface of the heating tank 2, a material turning assembly 5 inside the heating tank 2, the material turning assembly 5 including a fixed barrel 51 fixedly connected to the bottom inner wall surface of the heating tank 2, a feeding port 52 evenly distributed on the bottom surface of the fixed barrel 51, heating rods 53 evenly fixedly connected to the surface of the fixed barrel 51, a discharge port 54 on the top surface of the fixed barrel 51, a rotating shaft 55 rotatably connected between the inner walls of the heating tank 2, and a conveying auger 56 fixedly connected to the surface of the rotating shaft 55. A drive motor 57 is fixedly connected to the bottom surface of the heating tank 2. A discharge pipe 58 is fixedly connected to the bottom surface of the heating tank 2. A solenoid valve 59 is installed inside the discharge pipe 58. A cleaning assembly 6 is installed inside the heating tank 2. The top of the fixed tank 51 does not contact the inner wall of the top of the heating tank 2. The inlet 52 is located at the bottom of the heating tank 2. A conveying auger 56 is rotatably connected to the inside of the fixed tank 51. The length of the conveying auger 56 is greater than the length of the fixed tank 51. The output shaft of the drive motor 57 is fixedly connected to the top of the rotating shaft 55 through a coupling. When the surfactant raw material needs to be heated, the operator first slowly pours the surfactant raw material to be heated into the feeding hopper 3. The feeding hopper 3 is fixedly connected to the top of the heating tank 2. The raw material slides down the inner wall of the feeding hopper 3 and enters the heating tank 2. Inside the heating barrel 2, due to gravity, the raw materials first accumulate at the bottom of the heating barrel 2. At this time, the heating barrel 2 is in the initial state of preparation for heating. After the drive motor 57 starts, its output shaft begins to rotate at high speed. The output shaft is tightly connected to the top of the rotating shaft 55 through a coupling. The coupling plays the role of transmitting torque and buffering shock absorption, ensuring that the power can be transmitted stably and efficiently. As the output shaft rotates, the rotating shaft 55 also begins to rotate synchronously. The conveying auger 56 rotates inside the fixed barrel 51 along with the rotation of the rotating shaft 55. The raw materials accumulated at the bottom of the heating barrel 2 will enter the fixed barrel 51 through these feed ports 52. When the conveying auger 56 rotates, its blades will generate thrust and lifting force on the raw materials entering the fixed barrel 51. Under the push of the blades, the raw materials... The material is continuously conveyed upwards along the spiral direction of the conveying auger 56. Since the length of the conveying auger 56 is greater than the length of the fixed barrel 51, the material can be fully lifted, ensuring that the material entering from the inlet 52 at the bottom of the fixed barrel 51 can smoothly reach the outlet 54 at the top of the fixed barrel 51. During the upward conveying process of the material by the conveying auger 56, the heating rods 53, which are uniformly fixedly connected to the surface of the fixed barrel 51, begin to function. The heating rods 53 use high-efficiency heating elements that can quickly generate heat after being energized. These heating rods 53 are evenly distributed on the surface of the fixed barrel 51, creating a uniform heating environment inside the fixed barrel 51. When the material passes near the heating rods 53, heat is rapidly transferred to the material, causing its temperature to gradually rise.After the raw material reaches the discharge port 54 at the top of the fixed barrel 51, it flows out from the discharge port 54 and falls back into the heating barrel 2. Because the temperature inside the heating barrel 2 is relatively high, and the raw material exchanges heat with the surrounding environment and other heated materials during its descent, this further promotes uniform heat distribution. Subsequently, the raw material re-enters the fixed barrel 51 through the feed port 52, is conveyed upwards again by the conveying auger 56, and receives further heating. This cycle repeats continuously, with the raw material constantly tumbling and being heated within the heating barrel 2, ensuring uniform heating and preventing localized overheating or underheating.
[0020] Please see Figure 1 - Figure 3 The cleaning component 6 includes an L-shaped cleaning plate 61 uniformly fixedly connected to the surface of the rotating shaft 55. A discharge scraper 62 is fixedly connected to the bottom surface of the L-shaped cleaning plate 61. A stabilizing ring 63 is fixedly connected to the end of the discharge scraper 62 away from the L-shaped cleaning plate 61. The surface of the end of the L-shaped cleaning plate 61 away from the rotating shaft 55 abuts against the inner wall surface of the heating tank 2. The bottom surface of the discharge scraper 62 abuts against the bottom inner wall surface of the heating tank 2. The stabilizing ring 63 is rotatably connected to the surface of the fixed tank 51. When the raw material is heated to the required temperature, a discharge operation is required. At this time, the operator opens the solenoid valve 59 inside the discharge pipe 58. The solenoid valve 59 is a device that controls the opening and closing of a valve by electromagnetic force. It has the characteristics of fast response speed and high control accuracy. When the solenoid valve 59 is opened, it drives the drive motor 57 to reverse, which drives the conveying auger 56 to reverse, so that the raw material inside the fixed tank 51 is discharged from the inlet 52. At the same time, the discharge pipe 58... The heating tank 2 is connected to the interior. The heated raw material is discharged from the bottom of the heating tank 2 through the discharge pipe 58 under the action of gravity. As the rotating shaft 55 continues to rotate, the L-shaped cleaning plate 61 also rotates. The surface of the L-shaped cleaning plate 61 away from the rotating shaft 55 always keeps in close contact with the inner wall surface of the heating tank 2, like a scraper, scraping off the residual raw material attached to the inner wall of the heating tank 2. The bottom surface of the L-shaped cleaning plate 61 is fixedly connected to the discharge scraper 62. The bottom surface of the discharge scraper 62 is in close contact with the bottom inner wall surface of the heating tank 2. When the discharge scraper 62 rotates with the rotating shaft 55, it scrapes the residual raw material on the bottom inner wall of the heating tank 2 toward the discharge pipe 58, which can effectively collect and guide the residual raw material, ensuring that the raw material can be discharged smoothly from the discharge pipe 58. The stabilizing ring 63 plays a role in stabilizing the discharge scraper 62 and the L-shaped cleaning plate 61, ensuring the stability of the cleaning component 6 during the rotation process.
[0021] Working Principle: During operation, the surfactant raw material to be heated is first added to the heating tank 2 from the feeding hopper 3. The raw material slides down the inner wall of the heating tank 2 to the bottom. At this time, the drive motor 57 starts, and its output shaft drives the rotating shaft 55 to rotate through the coupling. The rotation of the rotating shaft 55 in turn drives the conveying auger 56 to rotate inside the fixed tank 51. Since the conveying auger 56 is rotatably connected inside the fixed tank 51 and its length is greater than the length of the fixed tank 51, when the conveying auger 56 rotates, it will continuously convey the raw material that has entered the bottom of the fixed tank 51 from the feed port 52 upwards. During the conveying process, the heating rods 53 evenly arranged on the surface of the fixed tank 51 heat the raw material. The heated raw material flows out from the discharge port 54 at the top of the fixed tank 51 and falls back into the heating tank 2. This cycle is repeated to achieve the turning and uniform heating of the raw material in the heating tank 2. During the heating process, the operator can observe the heating status of the raw material in the heating tank 2 through the observation port 4. When the heating is completed, the discharge port is opened. The solenoid valve 59 inside pipe 58 discharges the heated raw material from the discharge pipe 58. Simultaneously, as the rotating shaft 55 rotates, the L-shaped cleaning plates 61, which are uniformly fixed to its surface, also rotate. The surface of the L-shaped cleaning plate 61 away from the rotating shaft 55 always abuts against the inner wall surface of the heating tank 2, thereby scraping and cleaning the residual raw material adhering to the inner wall of the heating tank 2. The discharge scraper 62, which is fixedly connected to the bottom surface of the L-shaped cleaning plate 61, abuts against the bottom inner wall surface of the heating tank 2. During rotation, it scrapes the residual raw material on the bottom inner wall of the heating tank 2 towards the discharge pipe 58 for easy discharge. The stabilizing ring 63, which is fixedly connected to the end of the discharge scraper 62 away from the L-shaped cleaning plate 61, is rotatably connected to the surface of the fixed tank 51. It plays a role in stabilizing the discharge scraper 62 and the L-shaped cleaning plate 61, ensuring the stability of the cleaning component 6 during rotation, so that the cleaning work can be carried out smoothly and preventing the accumulation of residual raw material in the heating tank 2 from affecting subsequent production.
