Description

Technical Field

[0001] The utility model relates to the technical field of ethylenebistetrabromophthalimide production, in particular to a purification device for ethylenebistetrabromophthalimide production. Background Art

[0002] Ethylene bis-tetrabromophthalimide is a white prismatic crystal with a density of 2.732 g / cm3 and a melting point of 446°C. Ethylene bis-tetrabromophthalimide is soluble in alkaline solution and boiling acetic acid, slightly soluble in water, ethanol, and soluble in benzene. It is mainly used as an intermediate for the synthesis of various fine chemicals, the production of ion exchange resins and surfactants, etc.

[0003] In the production process of ethylenebistetrabromophthalimide, the purification step usually involves solvent extraction. However, in this process, the organic solvent and the target compound are simply statically mixed, resulting in insufficient contact between the organic solvent and the target compound, which in turn affects the extraction efficiency. This is because the static mixing method cannot ensure effective mass transfer and interphase mass transfer, so the extraction efficiency is not satisfactory. In addition, the existing device cannot be disassembled due to its special structure, and it is not convenient to clean the inside of the device.

[0004] Therefore, it is necessary to provide a purification device for producing ethylenebistetrabromophthalimide to solve the above technical problems. Utility Model Content

[0032] A discharge pipe 15 is fixedly installed and inserted at the bottom of the extraction tank 2, a vertical moving mechanism is provided on one side of the bottom of the extraction tank 2, a driving mechanism is provided on one side of the top of the base plate 1, and a reinforcement member 9 is fixedly installed between the tops of the two support plates 5. The provision of the reinforcement member 9 improves the integrity of the two support plates 5 and ensures synchronous stability during use.

[0033] The connection between the cover plate 11 and the top of the extraction tank 2 is stepped, and a sealing gasket is provided at the connection between the cover plate 11 and the top of the extraction tank 2. A plurality of tabs 22 are installed between the outer side of the cover plate 11 and the upper side of the outer wall of the extraction tank 2, which can ensure a stable connection between the cover plate 11 and the extraction tank 2 and provide good sealing. A sealing gasket is provided at the connection to further enhance the sealing effect.

[0034] In one of the embodiments, a plurality of balls 19 are movably mounted on the outer surface of the slider 18, and the balls 19 are in rolling contact with the inner wall of the slide groove 17, thereby reducing the friction between the slider 18 and the slide groove 17, improving the efficiency of the motor 14, and reducing the wear of the slider 18, thereby increasing the service life of the slider 18.

[0035] In one of the preferred embodiments, the vertical moving mechanism includes a guide wheel 4, and the guide wheel 4 is fixedly installed on one side of the bottom of the extraction tank 2. A guide platform 3 is fixedly installed on the top of the substrate 1, and the top of the guide platform 3 is inclined. The guide wheel 4 is in rolling contact with the top of the guide platform 3. The vertical reciprocating movement of the device is achieved with the help of the lateral moving mechanism of the device, which reduces the operating cost of the device and improves the practicability of the device.

[0036] In one embodiment, the driving mechanism includes a mounting frame 16, and the mounting frame 16 is fixedly mounted on one side of the top of the substrate 1, a motor 14 is fixedly mounted on the top of the mounting frame 16, a cam plate 13 is fixedly mounted on the driving end of the motor 14, a pressure plate 12 is fixedly mounted on one side of a support plate 5, and the pressure plate 12 is in conflict with the cam plate 13.

[0037] In one preferred embodiment, a sliding hole matched with the limiting rod 20 is opened on one side of the sliding block 18, and the sliding block 18 is slidably connected with the limiting rod 20 through the sliding hole opened on one side thereof.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all connected to an external power supply and a control switch when in use, and the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When in use, the target compound is added to the interior of the extraction tank 2 through the feed pipe 10, and a certain proportion of organic solvent is poured into the interior of the extraction tank 2, and then the motor 14 is controlled by the switch to start working, and the driving end of the motor 14 drives the cam plate 13 to rotate, and when the side of the cam plate 13 away from the center approaches the pressing plate 12, the pressing plate 12 will be pressed. A thrust is generated to move the pressing plate 12 to the left, and the movement of the pressing plate 12 drives the support plate 5 to move. The movement of the support plate 5 drives the extraction tank 2 to move through the cooperation of the movable block 7 and the connecting block 6. At the same time, the movement of the support plate 5 drives the slider 18 to slide on the inner wall of the slide groove 17 and squeeze the spring 21. When the extraction tank 2 moves to the left, it drives the guide wheel 4 to move together, so that the guide wheel 4 rolls toward the top of the guide platform 3. The extraction tank 2 can be vertically lifted by the action of the guide platform 3 on the guide wheel 4. During the process, the extraction tank 2 will drive the movable block 7 to slide on the slideway 8. When the side of the cam plate 13 close to the center approaches the pressure plate 12, the cam plate 13 will lose the thrust on the pressure plate 12. At this time, under the elastic action of the spring 21, the slider 18 will be driven to drive the support plate 5 to reset, thereby driving the extraction tank 2 to reset to the right side. During the process of the extraction tank 2 resetting to the right side, the guide wheel 4 rolls from a high position to a low position on the top of the guide platform 3, so that the extraction tank 2 will also move vertically downward under the action of its own gravity during the process of resetting to the right side. Therefore, the motor 1 4 is driven to make the extraction tank 2 produce a vertical and horizontal reciprocating motion simultaneously, so that the compound inside the extraction tank 2 is fully in contact with the organic solvent, thereby improving the extraction efficiency and quality. Subsequently, the shaking of the extraction tank 2 is stopped, and the mixture is waited for to be naturally stratified to form two layers of different phases, usually the upper layer is the water phase, and the lower layer is the organic solvent phase. The discharge pipe 15 is opened, and the organic phase containing the target compound is collected into another clean container. Finally, the target compound can be extracted from the organic solvent by distillation or evaporation of the solvent to obtain a pure target compound.

[0039] During use of the device, the cover plate 11 is fixed to the top of the extraction tank 2 by the buckle connection of the tower buckle 22, so that a detachable structure is formed for the cover plate 11, and the detachable structure is easy to operate, which is convenient for the user to quickly disassemble and assemble the cover plate 11. After the device is used, the cover plate 11 is removed, and through the top opening of the extraction tank 2, the user can easily clean the inside of the extraction tank 2 efficiently and thoroughly, thereby ensuring the subsequent use effect of the device, and having extremely high practicality.
