Description

Technical Field

[0001] This utility model relates to the field of distillation equipment, and in particular to an aromatic solvent distillation mechanism. Background Technology

[0002] In the chemical industry, the distillation technology of aromatic solvents is a crucial process that relies on precise temperature control and efficient thermal energy management to achieve the separation of high-purity monomeric aromatics.

[0003] Traditional aromatic solvent distillation mechanisms, while meeting basic production needs to a certain extent, still have room for improvement in terms of energy efficiency and operational safety. In particular, during processing, because the preparation tank is directly exposed to the external environment, a significant amount of heat is lost through the tank surface during distillation. This not only reduces energy efficiency but also increases production costs. To significantly reduce heat loss during distillation by incorporating an insulated structure, while also facilitating assembly, an aromatic solvent distillation mechanism is proposed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a tubular aromatic solvent distillation mechanism. It features an external insulation structure wrapped around the aromatic solvent distillation tank, with extendable layers that can be connected to the upper and lower ends of the insulation structure. This allows for easy assembly according to the external shape of the aromatic solvent distillation tank. The insulation structure has several first support rods on its exterior, and the extendable layers have several second support rods on their exterior for support, ensuring a tight and stable fit. Furthermore, the open design of both the insulation structure and the extendable layers facilitates easy folding and improves operational flexibility. All of these features prevent significant heat loss through the surface of the aromatic solvent distillation tank during distillation when exposed to the external environment.

[0005] To solve the above-mentioned technical problems, this utility model solves the problem of reducing heat loss during distillation in the application of the tubular aromatic solvent distillation mechanism through the following technical solution.

The insulation structure has an assemblable extension layer. The exterior of the insulation structure is supported by a plurality of first support rods, and the exterior of the extension layer is supported by a plurality of second support rods.

Example

[0035] Please see Figure 1 - Figure 9 An aromatic solvent distillation mechanism includes an aromatic solvent distillation tank 1, the exterior of which is tightly covered with a heat insulation structure 2. The heat insulation structure 2 is provided with an assemblable extension layer 6. The exterior of the heat insulation structure 2 is supported by a number of first support rods 4, and the exterior of the extension layer 6 is supported by a number of second support rods 602.

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The aromatic solvent distillation mechanism of this application is mainly composed of an aromatic solvent distillation tank 1 and other structures. By wrapping the aromatic solvent distillation tank 1 with an insulation structure 2, and connecting any extension layer 6 at the upper and lower ends of the insulation structure 2, it is convenient to assemble according to the external shape of the aromatic solvent distillation tank 1. The combination of the insulation structure 2 and the extension layer 6 can prevent a large amount of heat energy from being lost through the surface of the aromatic solvent distillation tank 1 during the distillation process when the aromatic solvent distillation tank 1 is exposed to the external environment. The insulation structure 2 and the extension layer 6 are designed to fit tightly against the surface of the aromatic solvent distillation tank 1. Several first support rods 4 are set on the outside of the insulation structure 2, and several second support rods 602 are set on the outside of the extension layer 6 for support, to ensure tightness and stability of the fit. At the same time, the insulation structure 2 and the extension layer 6 are designed with openings, which makes it convenient for operators to retract and improves the flexibility of operation.

[0037] It should also be noted that the insulation structure 2 and the extension layer 6 are both made of glass wool, which is a loose and soft fiber product made by melting glass at high temperature, spinning it, and then processing it with a special process. It has good thermal insulation performance, sound insulation performance, fire resistance performance and sound absorption performance.

[0038] This application also includes an upper support hoop 3, a lower support hoop 301, a support sleeve 601, and a positioning block 603. The upper support hoop 3 is glued to the upper ring of the insulation structure 2, the lower support hoop 301 is glued to the lower ring of the insulation structure 2, and the support sleeve 601 is glued to the upper and lower rings of the extension layer 6, respectively. The upper support hoop 3, lower support hoop 301, and support sleeve 601 are all elastic, allowing them to maintain their elasticity when the insulation structure 2 or the extension layer 6 covers the corresponding position on the outer surface of the aromatic solvent distillation tank 1. A certain force is generated between the outer walls, which supports the insulation structure 2 or the extension layer 6 and facilitates assembly. The upper support hoop 3 and the lower support hoop 301 are provided with grooves. The extension layer 6 is connected to the support sleeve 601, which can be inserted into the groove of the upper support hoop 3 or the lower support hoop 301 for movement. In this way, when adding to the upper or lower end of the insulation structure 2, the appropriate extension layer 6 can be cut and positioned at the upper or lower end of the insulation structure 2 to ensure the stability of the splicing and to perform positioning treatment at the connection.

[0039] This application also includes an inner stabilizing ring 5, which surrounds the inner wall of the groove of the upper support hoop 3 or the lower support hoop 301. Both the inner stabilizing ring 5 and the positioning block 603 are designed to be made of magnetically attractive material. This allows the positioning block 603 to be magnetically attracted to any position on the inner stabilizing ring 5 after the support hoop 601 is brought into the groove of the support hoop 3 or the lower support hoop 301, thereby improving the stability of the connection between the extension layer 6 and the insulation structure 2 after assembly.

[0040] This application also includes an insertion structure 501, which is located on the side of the inner stabilizing ring 5 that contacts the groove of the upper support hoop 3 or the lower support hoop 301. After the inner stabilizing ring 5 is assembled, the insertion structure 501 can be inserted into the corresponding groove in the upper support hoop 3 or the lower support hoop 301. This facilitates the installation and disassembly of the inner stabilizing ring 5. The insertion end of the insertion structure 501 is relatively large and has a certain degree of elasticity, which can increase the friction of the insertion surface and improve stability.

[0041] This application also includes a first magnetic structure 201, a second magnetic structure 202, and a protruding insert 203. The first magnetic structure 201 and the second magnetic structure 202 are respectively glued to both sides of the insulation structure 2. When the insulation structure 2 surrounds the handle and covers the outside of the aromatic solvent distillation tank 1, the first magnetic structure 201 and the second magnetic structure 202 are magnetically attracted together due to the magnetic material design between them, thus ensuring the stability of the connection at the opening of the insulation structure 2. When the first magnetic structure 201 and the second magnetic structure 202 are magnetically attracted together, the protruding insert 203 is driven to be inserted into the groove of the first magnetic structure 201, thereby positioning the connection between the first magnetic structure 201 and the second magnetic structure 202. The protruding insert 203 and the second magnetic structure 202 are an integral structure design.

[0042] This application also includes a positioning plate 7, a positioning end 701, a handle 702, and a base 703. The positioning plate 7 is elastic and connects to the positioning end 701, causing the positioning end 701 to be pressed against the outer wall of the connection between the second magnetic structure 202 and the first magnetic structure 201, thus locking the connection and preventing the overall structure of the insulation structure 2 from shifting downwards. The positioning end 701 is made of rubber and can contact the outer walls of the first magnetic structure 201 and the second magnetic structure 202, thereby increasing the friction of the contact surface and improving the stability during the positioning process. The handle 702 is installed on the outer wall of the positioning plate 7, making it convenient to pull the positioning plate 7 outwards. The base 703 is an integral structure with the positioning plate 7, making it convenient to support the positioning plate 7 at the corresponding position on the outer wall of the aromatic solvent distillation tank 1, and placing the insulation structure 2 on it.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
