Description

Technical Field

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

[0002] The distillation of aromatic solvents is a complex and delicate process. Its core lies in using heating and condensation mechanisms to precisely separate the different components in a mixture, thereby obtaining high-purity monomeric aromatics. This process plays a crucial role in chemical production because aromatic solvents demonstrate wide-ranging applications in various industrial fields, such as paint manufacturing, ink formulation, resin synthesis, and as solvents and reaction media.

[0003] In the operation of traditional aromatic solvent distillation equipment, the feed mixture is often directly poured into the distillation tank, followed by heating to start the distillation process. After distillation, the liquid is discharged through the feed inlet, typically with a container at the inlet to collect the overflowing liquid. However, due to variations in container size and shape, precise alignment between the container and the feed inlet is often difficult to ensure. This direct discharge method carries inherent risks, especially when the liquid is not accurately centered within the tank during pouring or is obstructed by the tank's edges, easily leading to leakage. Such leakage not only results in unnecessary loss of feed but also poses a potential environmental pollution threat and increases safety risks during operation. Therefore, an aromatic solvent distillation device is proposed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an aromatic solvent distillation apparatus. An oil discharge container is disposed at the discharge port of the liquid outlet pipe. The container has a movable opening at its top, precisely aligned with the discharge port of the liquid outlet pipe. Inside this movable opening, a movable guide pipe is designed. By adjusting the position of the guide pipe, its opening can be fitted onto the outer ring of the liquid outlet pipe, thus creating a smooth material discharge channel. When the material is discharged, the raw material mixture flows smoothly along the inner wall of the guide pipe into the central area of ​​the container. This design not only ensures effective material guidance but also significantly reduces the risk of liquid leakage.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problems existing in the discharge process of aromatic solvent distillation equipment through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An aromatic solvent distillation apparatus includes a distillation tank mounted on an aromatic solvent distillation rack. One end of the distillation tank is connected to an outlet pipe, and a container is provided at the outlet of the outlet pipe for collection. The container has an opening aligned with the outlet of the outlet pipe, and a movable guide pipe is provided inside the opening. One end of the guide pipe extends into the container, and the other end is fitted onto the outlet of the outlet pipe.

[0008] Preferably, the guide pipe inlet is connected to a pipe opening, the guide pipe is sleeved outside the outlet of the liquid outlet pipe through the pipe opening, and one end of the container is provided with an outlet structure.

[0009] Preferably, a limiting sleeve is connected to the outer ring of the outlet pipe to limit the pipe opening.

[0010] Preferably, the limiting sleeve and the pipe opening are sealed by a sealing ring.

[0011] Preferably, an inner groove is provided at the upper opening of the pipe, and one end of the sealing ring is connected to the inner wall of the limiting sleeve cover, while the other end is locked inside the inner groove.

[0012] Preferably, a plurality of protective rings are glued to the inner wall and make contact with the ring opening on the tube opening.

[0013] Preferably, one end of the movable opening is connected to an internal plate with a movable groove, and one end of the outer wall of the guide pipe is connected to a movable block that can move inside the movable groove. A positioning spring is provided between the movable groove and the movable block.

[0014] Preferably, a filter structure is connected to the inner ring of the pipe opening.

[0015] Preferably, symmetrical limiting plates are provided on both sides of the outlet pipe to guide the limiting of the pipe, and an inner convex layer is glued to the inner wall of the limiting plate.

[0016] Preferably, the end of the limiting plate facing the distillation tank is connected to a locking plate, which can be locked into the groove of the distillation tank support.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The aromatic solvent distillation equipment provided in this application uses an oil discharge container disposed at the discharge port of the liquid outlet pipe. The container has a movable opening at the top, which is precisely aligned with the discharge port of the liquid outlet pipe. Inside the movable opening, a movable guide pipe is designed. By adjusting the position of the guide pipe, its opening can be fitted onto the outer ring of the outlet of the liquid outlet pipe, thereby constructing a smooth material discharge channel. When the material is discharged, the raw material mixture can flow smoothly into the central area of ​​the container along the inner wall of the guide pipe. This design not only ensures the effective guidance of the material, but also significantly reduces the risk of liquid leakage.

[0019] This application sets a limiting sleeve, which can cause the pipe opening to come into contact with the limiting sleeve when the guide pipe is sleeved at the outlet of the liquid outlet pipe, thereby restricting the sleeve position.

[0020] This application incorporates a built-in plate, a movable groove, a movable block, and a positioning spring. When the guide tube moves up and down inside the movable port, it can drive the movable block to move in the same direction inside the movable groove, thus ensuring the stability of the guide tube during its overall movement. The designed positioning spring itself is elastic and can squeeze the tube opening into the limiting sleeve, thereby ensuring the stability of the connection between the guide tube and the liquid outlet tube.

Example

[0037] Please see Figure 1 - Figure 10 An aromatic solvent distillation apparatus includes a distillation tank 101 mounted on an aromatic solvent distillation rack 1. One end of the distillation tank 101 is connected to an outlet pipe 102. A container 2 is provided at the outlet of the outlet pipe 102 for collection. The container 2 has an opening 201 aligned with the outlet of the outlet pipe 102. A movable guide pipe 3 is provided inside the opening 201. One end of the guide pipe 3 extends into the container 2, and the other end is fitted onto the outlet of the outlet pipe 102.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 This utility model of an aromatic solvent distillation device mainly consists of an aromatic solvent distillation rack 1, a distillation tank 101, and an outlet pipe 102. The aromatic solvent distillation rack 1 supports the entire upper structure. At one end of the device, the outlet pipe 102 is configured to discharge the material. To effectively collect the material, a collection device container 2 is placed at the discharge port of the outlet pipe 102. The top of the collection device has an open movable port 201, which is precisely aligned with the discharge port of the outlet pipe 102. Inside the open movable port 201, a movable component guide pipe 3 is designed. By adjusting the position of the guide pipe 3, its opening can be fitted onto the outer ring of the outlet of the outlet pipe 102, thereby creating a smooth material discharge channel. When the material is discharged, the raw material mixture can flow smoothly into the central area of ​​the container 2 along the inner wall of the guide pipe 3. This design not only ensures the effective guidance of the material but also significantly reduces the risk of liquid leakage.

[0039] This application also includes a port 301, which is an integral structure with the guide pipe 3. Through the design of the port 301, the guide pipe 3 can be accurately fitted onto the outer ring of the outlet of the liquid outlet pipe 102.

[0040] This application also includes a discharge structure 202, which is installed at the lower end of one end of the container 2. The discharge structure 202 is also equipped with a valve, which can be opened to evenly guide the contents into another small collection device to improve the application effect.

[0041] This application also includes a limiting sleeve 303, which is fixedly installed on the outer ring of the outlet of the liquid outlet pipe 102. When the guide pipe 3 is sleeved outside the outlet of the liquid outlet pipe 102, it can cause the pipe opening 301 to come into contact with the limiting sleeve 303, thereby limiting the sleeve connection.

[0042] This application also includes a sealing ring 304 and an inner groove 306. The sealing ring 304 is provided on the side of the pipe opening 301 that contacts the limiting sleeve 303. The sealing ring 304 is designed for sealing at the connection. An inner groove 306 is provided at the upper opening of the pipe opening 301. One end of the sealing ring 304 is connected to the inner wall of the limiting sleeve 303. When the other end comes into contact between the pipe opening 301 and the limiting sleeve 303, it causes the sealing ring 304 to be locked inside the inner groove 306, thereby further improving the sealing effect of the connection between the limiting sleeve 303 and the pipe opening 301.

[0043] This application also includes a protective ring 305, which is glued to the inner wall of the limiting sleeve 303. The protective ring 305 is made of rubber and can protect the contact surface when the guide pipe 3 moves up and down along the inside of the container 2 and touches the inner wall of the limiting sleeve 303, generating force.

[0044] This application also includes an internal plate 4, a movable groove 401, a movable block 402, and a positioning spring 403. The internal plate 4 is fixed to one side of the inner wall of the movable opening 201. The movable block 402 is connected to the end of the outer wall of the guide pipe 3 facing the internal plate 4. The internal plate 4 has a movable groove 401 inside, which allows the movable block 402 to move within it. When the guide pipe 3 moves up and down inside the movable opening 201, it can drive the movable block 402 to move in the same direction inside the movable groove 401, thus ensuring the stability of the guide pipe 3 when it moves as a whole. The positioning spring 403 is elastic. One end of it is connected to the bottom of the inner wall of the movable groove 401, and the other end is connected to the movable block 402. When the guide pipe 3 is aligned with the outlet of the liquid pipe 102, it can squeeze the pipe opening 301 into the limiting sleeve 303, thus ensuring the stability of the connection between the guide pipe 3 and the liquid pipe 102.

[0045] It should also be noted that the design of one end of the guide tube 3 extending into the interior of the container 2 and being able to move relative to the movable port 201 allows the container 2 to be removed. When removing the container 2, the guide tube 3 can be moved down to squeeze the positioning spring 403, thereby disengaging the guide tube 3 from the outlet of the liquid outlet pipe 102. After disengagement, it can be pulled forward to remove the container 2 and the guide tube 3, thus improving the convenience of disassembly and assembly.

[0046] This application also includes a filter structure 302, which is designed on the inner wall of the pipe opening 301. When the material inside the liquid outlet pipe 102 flows into the guide pipe 3, it can screen out large impurities in the initially entering material. The material is a liquid mixture. The filter structure 302 is connected to the pipe opening 301 by adhesive bonding, and can be disassembled and assembled according to usage requirements.

[0047] This application also includes a limiting plate 5, a snap-fit ​​plate 501, and an inner convex layer 502. The limiting plate 5 is located on both sides of the liquid outlet pipe 102. When the container 2 is installed, the guide pipe 3 designed on it enters the liquid outlet pipe 102 through the inside of the limiting plate 5 on both sides to prevent misalignment and inaccurate docking. The inner convex layer 502 is glued to the inner wall of the limiting plate 5. When the guide pipe 3 is inserted and comes into contact, it can protect the contact surface. The inner convex layer 502 is made of rubber. The snap-fit ​​plate 501 and the limiting plate 5 are designed as an integral structure. The snap-fit ​​plate 501 can be snapped into the groove at the support of the distillation tank 101 from top to bottom. After snapping, the limiting plate 5 can be installed, which also facilitates subsequent removal.

[0048] 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.
