A high waste isooctanol treatment device for preparing crude p-xylene and refined p-xylene

Abstract

This utility model discloses a high-waste isooctyl alcohol treatment device for the preparation of crude and refined p-benzene. It includes a chemical filtration separation box with a door panel on the front. The device also includes an absorption chamber, which is positioned opposite each other on the surface of the door panel. A sealing gasket is also provided on the surface of the door panel. In this design, a fan located on the front of the chemical filtration separation box generates airflow, preventing volatile organic compounds from directly escaping and impacting the surrounding environment when the door panel is opened. Furthermore, by horizontally moving the fixing plate, the spring inside the connecting column deforms, and one side of the locking seat separates from the side of the connecting column. This allows the connecting column to be moved horizontally, enabling the mounting frame to be pulled out of the connecting chamber for cleaning the adsorption layer after long-term use. This facilitates quick disassembly and maintenance of the adsorption layer, improving the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of chemical preparation technology, and more specifically, to a high-waste isooctyl alcohol treatment device for the preparation of crude and refined p-benzene. Background Technology

[0002] In the process of preparing crude and refined p-benzene, it is usually necessary to use a corresponding device to filter isooctyl alcohol containing high levels of waste. However, the filter baskets in the existing filtration devices often need to be cleaned regularly, but the disassembly structure of the filter baskets is relatively complex, making them inconvenient to disassemble and install.

[0003] To address the aforementioned issues, patent document publication number CN222033804U discloses an integrated chemical preparation filtration and separation machine, comprising a chemical filtration and separation chamber. The chemical filtration and separation chamber includes a cavity one and a cavity two. A stirring assembly is installed inside the cavity one, and a chemical preparation filtration and separation assembly is installed inside the cavity two. The chemical preparation filtration and separation assembly includes a filter basket, two mounting plates, two fixing plates, and a limiting assembly.

[0004] However, it still has some drawbacks in actual use. For example, the above-mentioned device has a simple structure and is easy to disassemble and install the filter screen by using the setting of the limiting component and the cooperation of the electric push rod, the double-threaded rod, the moving plate, the limiting block and the electric push rod. However, when the door panel is opened to remove the filter basket, the lack of a waste gas collection mechanism at the door panel causes volatile organic compounds to escape directly, which can easily affect the surrounding environment and reduce the practicality of the device to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-waste isooctyl alcohol treatment device for the preparation of crude and refined p-benzene, so as to solve the problem that when the door panel is opened and the filter basket is disassembled, the volatile organic compounds are directly released and easily affect the surrounding environment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-waste isooctyl alcohol treatment device for the preparation of crude and refined p-benzene, comprising a chemical filtration separation box, wherein a door panel is provided on the front of the chemical filtration separation box, and the high-waste isooctyl alcohol treatment device for the preparation of crude and refined p-benzene further includes...

[0007] Absorption chambers are disposed opposite each other on both sides of the door panel surface;

[0008] A sealing gasket is provided on the surface of the door panel, and the inner ring of the sealing gasket is in contact with the outer periphery of the absorption cavity.

[0009] A fan is fixedly installed on the front of the chemical filtration separation box. The air outlet of the fan is fixedly connected to a connecting pipe one. The bottom end of the connecting pipe one is fixedly connected to a connecting chamber. One side of the connecting chamber is fixedly connected to the front of the chemical filtration separation box. The bottom of the connecting chamber is fixedly connected to a connecting pipe two. The end of the connecting pipe two relative to the connecting chamber is connected to the side of the absorption chamber.

[0010] A connecting column, on the surface of which an installation frame is fixedly mounted, the outer periphery of which is in contact with the inner wall of the connecting compartment, and the inner wall of which is provided with an adsorption layer;

[0011] A second sealing gasket is disposed on the front of the connecting compartment, and the inner ring of the second sealing gasket is fitted to the outer periphery of the mounting frame.

[0012] The device also includes a fixing frame, which is fixedly installed on the front of the connecting compartment. A spring is fixedly connected inside the fixing frame, and a sleeve post is fixedly connected to one end of the spring relative to the fixing frame. The surface of the sleeve post is slidably connected to the inner wall of the fixing frame. A fixing plate is fixedly installed at one end of the sleeve post along its length. A snap-fit ​​seat is provided on one side of the fixing plate, and one side of the snap-fit ​​seat passes through the fixing frame and snaps into the side of the connecting post.

[0013] It also includes a fixing component, which is disposed on the surface of the door panel.

[0014] The fixing assembly includes a connecting seat, a fixing column, a second spring, a movable column, a connecting plate, and a snap-fit ​​plate. The fixing column is fixedly connected to the surface of the door panel through the connecting seat. One end of the second spring is fixedly connected to the inside of the fixing column, and the other end of the second spring is fixedly connected to the inner wall of the movable column. The surface of the movable column is slidably connected to the inner wall of the fixing column. The connecting plate is fixedly installed on the side of the movable column. The snap-fit ​​plate is disposed on the surface of the connecting plate, and the surface of the snap-fit ​​plate snaps against the surface of the absorption cavity.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, when the door panel is opened and closed, the fan set on the front of the chemical filtration separation box generates airflow, so that the waste gas generated during the operation of the chemical filtration separation box can be absorbed through the two absorption chambers set on the surface of the door panel. The absorbed waste gas enters the connecting chamber through the second connecting pipe and is purified by the two adsorption layers. After purification, the waste gas is discharged to the outside, thus preventing volatile organic compounds from directly escaping and affecting the surrounding environment when the door panel is opened. In addition, by moving the fixed plate horizontally, the spring inside the sleeve column deforms, and one side of the snap-fit ​​seat separates from the side of the connecting column. At this time, the connecting column can be moved horizontally, so that the mounting frame can be pulled out of the connecting chamber for cleaning of the adsorption layer after long-term use. This enables quick disassembly and maintenance of the adsorption layer and improves the practicality of the device.

[0017] By moving the two movable columns toward each other, the second spring deforms, and the snap-fit ​​plate on the surface of the connecting plate moves synchronously. After the snap-fit ​​plate moves, it can be separated from the surface of the absorption chamber. At this time, the absorption chamber can be removed from the surface of the door panel to clean the inner wall of the absorption chamber and the connection between the second connecting pipe and the absorption chamber, so as to prevent impurities from adhering and affecting the gas flow.
