Description
Technical Field
[0001] This utility model belongs to the field of pseudoboehmite production technology, and in particular relates to a temperature control device for pseudoboehmite production. Background Technology
[0002] Boehmite, also known as monohydrate alumina or pseudo-monohydrate diatomite, is a non-toxic, tasteless, odorless, white colloidal (wet) or powder (dry) substance with high crystal purity, good colloidal properties, strong adhesion, high specific surface area, and large pore volume. Its aqueous state is a thixotropic gel.
[0003] Currently, in the carbonization process of pseudoboehmite production, a low-temperature, low-concentration industrial sodium aluminate solution is used as raw material. High-concentration CO2 gas is rapidly introduced as a precipitant to neutralize and form a gel. The gelation temperature and the final pH value are controlled. Then, after heating, aging, washing, and drying, ordinary pseudoboehmite products are obtained.
[0004] In the aging process of boehmite, the aging device needs to be heated to ensure the growth process of the material. However, conventional heating equipment often uses devices such as heating resistance wires, which are wound around the outside of the aging device. The temperature is easily controlled by controlling the operation of the heating resistance wires. Although this can facilitate the heating and aging of the material, the heating process is relatively slow and is also affected by the external environment, such as low temperature environment. This increases the time required to put the heating equipment into operation, and the heating effect is limited, which cannot meet the usage requirements. Utility Model Content

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Examples, such as Figures 1-4As shown, a temperature control device for the production of pseudo-boehmite includes a tank 1, a rotating shaft 11 inside the tank 1, and a feeding auxiliary tank 2 above the tank 1. The setup of these components is a mature and conventional technique, and the specific setup and operation are not detailed here. This embodiment aims to solve the problem of limited heating process in existing aging tanks. Specifically, a jacketed tank 12 is located inside the tank 1, and a heating component 3 is located between the tank 1 and the jacketed tank 12. The heating component 3 includes an input pipe 31, a distributor 5 at the end of the input pipe 31, an extension pipe 32 on the outside of the distributor 5, and an L-shaped connecting pipe 33 at the end of the extension pipe 32. One end of the connecting pipe 33 has a vertical pipe 34 located inside the jacketed tank 12, and a collecting pipe 35 located above the jacketed tank 12 and connected to the vertical pipe 34. The outside of the collecting pipe 35 is... An output pipe 36 is provided, extending to the outside of the tank body 1. Specifically, the input pipe 31 is connected to an external heat source, including but not limited to hot steam or hot water. Taking hot steam as an example, after being input through the input pipe 31, it is output to each vertical pipe 34 through the distributor 5. Since the vertical pipes 34 are located inside the tank body 1, their heat source can fully contact the material to achieve its heating process, ensuring the accuracy of temperature control. After the heat source flows in the vertical pipes 34, it is output to the outside and collected in the collecting pipe 35, and finally discharged through the output pipe 36. In this way, the heating process is relatively consistent by using the heat source flow to ensure the heating effect, providing convenient conditions for the aging of materials and meeting the usage requirements. An auxiliary heating mechanism 4 is provided above the distributor 5, which can assist in heating the outside of the tank body 1, especially creating a heating environment to ensure the smooth progress of subsequent work and meet the usage requirements.
[0021] In the above process: the heating component 3 can be used to heat the inside and outside of the tank 1 to ensure the heating process inside the tank 1, saving time and costs to a certain extent and ensuring the smooth progress of the heating work. At the same time, the auxiliary heating mechanism 4 can assist in heating the outside of the tank 1, especially creating a heating environment to ensure the smooth progress of subsequent work and meet the usage requirements. This device is reasonably designed, simple in structure, easy to process, and can realize convenient control of the heating process. It can also complete the synchronous heating process of the aging device to a certain extent, ensuring the relative stability of the processing temperature, improving the heating process, saving time and costs, ensuring the processing progress, and meeting the usage requirements.
[0022] To facilitate the distribution of the input heat source and ensure the smooth operation of the heating process, the distributor 5 includes a ring-shaped housing 51. Multiple stepped flow dividers 52 are evenly distributed within the housing 51. These flow dividers 52 distribute the input heat source evenly, allowing it to flow smoothly to each extension pipe 32, thus ensuring convenient heat source output and facilitating the heating process. The gaps between adjacent flow dividers 52 are connected to the input pipe 31 and the extension pipe 32, respectively. A ring-shaped cover 53 is installed on top of the housing 51 to protect it and ensure its effectiveness. A protective sleeve 54, made of heat-insulating material, is located at the geometric center of the housing 51 to protect the discharge pipe of the tank 1 and ensure the functionality of the device.
[0023] To further improve the rationality of the device setup, the auxiliary heating mechanism 4 includes an auxiliary pipe 41 located on the outside of the housing 51 opposite to the input pipe 31. A first ring pipe 42 is positioned above the auxiliary pipe 41, and a second ring pipe 43 is positioned above the first ring pipe 42. A connecting pipe 44 is provided between the first ring pipe 42 and the second ring pipe 43. An extension pipe 45 is positioned outside the second ring pipe 43, and the upper end of the extension pipe 45 is connected to the collecting pipe 35. Specifically, the first ring pipe 42 has an arc-shaped design and is arranged vertically with the second ring pipe 43. Their dimensions also differ, the purpose of which is to increase the heating range. In other words, the heat input through the input pipe 31... The heat source is partially transported upward through the extension pipe 32, and the other part is transported into the first ring pipe 42 through the auxiliary pipe 41, flowing within the ring pipe until it is transported into the second ring pipe 43 through the connecting pipe 44. The connecting pipe 44 is positioned corresponding to the center of the second ring pipe 43. In this way, the heat source is transported within the second ring pipe 43, then upward through the extension pipe 45, and finally discharged outward through the collecting pipe 35. During the above process, the heat source flows through the first ring pipe 42 and the second ring pipe 43, which can heat the bottom of the tank 1 to a certain extent. In conjunction with the heating component 3, it can conveniently heat the material inside the tank 1, improving the working process.
[0024] To ensure the smooth progress of the aging process, a material distributor 6 is installed on the rotating shaft 11 above the tank 1. Its function is to evenly distribute and guide the new material added into the tank 1 via the feeding auxiliary tank 2, so that the falling position of the material is relatively consistent, reducing the possibility of accumulation and ensuring the smooth progress of subsequent mixing. A stirring blade 7 is installed on the rotating shaft 11 below the material distributor 6, and a turning blade 8 is installed on the rotating shaft 11 below the stirring blade 7. The stirring blade 7 can stir and mix the material in the horizontal direction, and the turning blade 8 is twisted in a figure-eight shape, which can turn the material up and down to a certain extent, so that it can be stirred and mixed in the vertical direction. The establishment of the above mixing components makes the material processing more homogeneous, ensuring both molding quality and output uniformity, and meeting the usage requirements.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
