Description

Technical Field

[0001] This utility model relates to the field of methyl anthranilate preparation technology, and in particular to a sedimentation separation device. Background Technology

[0002] Methyl anthranilate is an organic compound that can be used directly in organic synthesis and is also widely used in pharmaceuticals, pesticides, fragrance processing, and fine chemicals. In the preparation of methyl anthranilate, multiple reaction steps are involved to form an esterification solution. This esterification solution contains insoluble impurities, therefore a sedimentation separation device is required to remove these impurities and obtain the methyl ester material.

[0003] Existing sedimentation separation devices typically involve adding the esterified liquid into a sedimentation tank and allowing it to settle naturally to achieve separation. However, these devices often lack a guiding structure during the sedimentation separation process, failing to aggregate the separated methyl ester phase. As a result, some methyl ester phase remains in the sedimentation tank during discharge, making it difficult to drain quickly. This not only wastes resources but also increases cleaning difficulty, hindering the cleaning of the sedimentation tank and ultimately impeding the effective use of sedimentation separation for esterified liquids. Utility Model Content

[0004] This invention proposes a sedimentation separation device to solve the problem that existing devices cannot aggregate the separated methyl ester phase, and some methyl ester phase remains in the sedimentation tank during discharge, making it difficult to discharge quickly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sedimentation separation device, including a sedimentation tank, a tank cover on the top of the sedimentation tank, and a water phase discharge valve connected to one side of the sedimentation tank. A feed pipe is connected to the tank cover. A guide protrusion is installed at the bottom of the sedimentation tank, and guide blocks are provided around the inner wall of the sedimentation tank. The guide protrusion is located in the middle of the guide blocks, and a material accumulation chamber is formed between the guide protrusion and the guide blocks. Two methyl ester phase discharge valves communicating with the material accumulation chamber are installed at the bottom of the sedimentation tank, and branch pipes are connected to the bottom ends of the two methyl ester phase discharge valves. One end of the two branch pipes is connected to a discharge pipe.

[0006] The settling tank is also equipped with a scraping structure, which includes a scraper plate that can rotate along the inside of the settling chamber. The scraper plate includes a horizontal scraping part, with a first side scraping part on one side and a second side scraping part on the other side.

[0007] Preferably, the scraping structure further includes a driving component for driving the scraper plate to rotate. The driving component includes a motor mounted on the top of the box cover and a shaft rotatably mounted on the top of the guide boss. The shaft is connected to the second side scraper by multiple connecting rods, and the top end of the shaft is connected to the main shaft of the motor by a key.

[0008] Preferably, a limiting and fixing structure for quick disassembly and assembly of the box cover is provided between the box cover and the top of the settling box. The limiting and fixing structure includes an ear block installed on the top of the settling box, and a cavity and an inner cavity opened in the box cover and communicating with each other. A locking block is provided in the inner cavity, and the locking block is connected to an elastic element that pushes it to lock into the bottom of the ear block.

[0009] Preferably, the elastic element includes a spring disposed in the inner cavity, one end of the spring is connected to a movable plate, the locking block is installed on one side of the movable plate, and the other side of the movable plate is connected to a pull rod extending to the outside of the box cover, with the spring sleeved on the outside of the pull rod.

[0010] Preferably, the bottom of the ear block extends downward to form a protrusion, and the top of the card block is obliquely cut to form a notch that matches the protrusion.

[0011] Preferably, one side of the protrusion extends outward to form a limiting block, and a limiting groove for the limiting block to be inserted is provided on the inner wall of the notch.

On the other hand, it reduces the cleaning difficulty of the sedimentation tank, facilitates the efficient cleaning of the sedimentation separation device, and facilitates the use of the sedimentation separation device.

[0014] (2) By setting up a limiting and fixing structure, it is possible to quickly assemble and disassemble the box cover and the settling box, thereby enabling the scraper to be disassembled, which is conducive to the quick replacement or cleaning of the scraper, ensuring the subsequent use of the scraper, and further realizing the rapid discharge of the methyl ester phase.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-9 The sedimentation separation device shown includes a sedimentation tank 1, a tank cover 2 on the top of the sedimentation tank 1, and a water phase discharge valve 5 connected to one side of the sedimentation tank 1. A feed pipe 4 is connected to the tank cover 2. A guide protrusion 11 is installed at the bottom of the sedimentation tank 1, and guide blocks 10 are provided around the inner wall of the sedimentation tank 1. The guide protrusion 11 is located in the middle of the guide block 10, and a material accumulation chamber is formed between the guide protrusion 11 and the guide block 10. Two methyl ester phase discharge valves 6 connected to the material accumulation chamber are installed at the bottom of the sedimentation tank 1, and the bottom ends of the two methyl ester phase discharge valves 6 are connected to branch pipes 7. One end of the two branch pipes 7 is connected to a discharge pipe 8.

[0030] The settling tank 1 is also provided with a scraping structure 3, and the scraping structure 3 includes a scraping plate 34 that can rotate along the inside of the settling chamber. The scraping plate 34 includes a horizontal scraping part 342. A first side scraping part 341 is provided on one side of the horizontal scraping part 342, and a second side scraping part 343 is provided on the other side.

[0031] Specifically, in order to achieve the rotation of the scraper 34, in this embodiment, as follows: Figures 1-3 as well as Figure 5 As shown, the scraping structure 3 also includes a driving component for driving the scraper plate 34 to rotate. The driving component includes a motor 31 mounted on the top of the box cover 2 and a shaft 32 rotatably mounted on the top of the guide boss 11. Multiple connecting rods 33 are connected between the shaft 32 and the second side scraper 343, and the top end of the shaft 32 is connected to the main shaft of the motor 31 by a key.

[0032] As described above, in the preparation of methyl anthranilate, the esterification liquid is added into the settling tank 1 through the feed pipe 4, and the device is kept still. After a period of time, the esterification liquid separates into layers in the settling tank 1, with the upper layer being the aqueous phase and the lower layer being the methyl ester phase. Then, the aqueous phase discharge valve 5 can be opened to discharge the aqueous phase. After the aqueous phase is discharged, the methyl ester phase discharge valve 6 is opened to discharge the methyl ester phase through the branch pipe 7 and the discharge pipe 8. This sedimentation and separation of the esterification liquid facilitates further processing and realizes the preparation of methyl anthranilate.

[0033] During the sedimentation process of the esterified liquid, the aggregate cavity formed between the guide block 10 and the guide boss 11 gathers the methyl ester phase, facilitating its rapid discharge and reducing its residue. The motor 31 drives the shaft 32 to rotate, which in turn drives the scraper 34 to rotate via the connecting rod 33. At this time, the horizontal scraper 342 cleans the bottom of the aggregate cavity, while the first side scraper 341 and the second side scraper 343 rotate along the inner walls of the aggregate cavity to clean the inner walls, removing any remaining methyl ester phase and discharging it through the methyl ester phase discharge valve 6. This cleaning of the inner walls of the aggregate cavity facilitates rapid and complete discharge of the methyl ester phase, preventing residue and resource waste. Furthermore, it facilitates cleaning of the sedimentation separation device, reducing cleaning difficulty and improving cleaning efficiency, thus simplifying its use.

[0034] In another embodiment, such as Figure 1 , Figure 2 as well as Figures 4-9 As shown, a limiting and fixing structure 9 for quick disassembly and assembly of the box cover 2 is also provided between the top of the box cover 2 and the settling box 1. The limiting and fixing structure 9 includes an ear block 94 installed on the top of the settling box 1, and a cavity 95 and an inner cavity that are opened in the box cover 2 and communicate with each other. A locking block 92 is provided in the inner cavity, and the locking block 92 is connected to an elastic element that pushes it to lock into the bottom of the ear block 94.

[0035] Specifically, the elastic element includes a spring 93 disposed in the inner cavity, one end of the spring 93 is connected to a movable plate, a locking block 92 is installed on one side of the movable plate, and the other side of the movable plate is connected to a pull rod 91 extending to the outside of the cover 2, with the spring 93 sleeved on the outside of the pull rod 91.

[0036] When the scraper plate 34 needs to be replaced, the pull rod 91 can be pulled. At this time, the pull rod 91 drives the movable plate to move along the inner cavity. Then, the movable plate drives the locking block 92 into the inner cavity and squeezes the spring 93, causing the spring 93 to contract. Then, the box cover 2 is lifted upward, so that the ear block 94 is moved out of the cavity groove 95, thereby separating the box cover 2 from the settling box 1. Then, the connecting rod 33 is removed from the shaft 32, and the scraper plate 34 is taken out from the settling box 1 for replacement. After replacement, the scraper plate 34 is connected to the settling box 1 by the connecting rod 33. The shaft 32 is connected so that the scraper 34 can be installed into the material collection chamber. Then, the box cover 2 is closed on the top of the settling box 1. At this time, the locking block 92 is pulled by the pull rod 91 so that the locking block 92 is retracted into the inner cavity. When the ear block 94 is fully inserted into the cavity groove 95, the pull rod 91 is released. At this time, under the action of the spring 93, the movable plate pushes the locking block 92 out of the inner cavity and stably locks it into the bottom of the ear block 94, so as to realize the quick disassembly and assembly between the box cover 2 and the settling box 1, which is conducive to the quick replacement or cleaning of the scraper 34 and can ensure the subsequent use of the scraper 34.

[0037] Furthermore, such as Figure 2 , Figure 4 , Figure 5 as well as Figures 7-9 As shown, the bottom of the ear block 94 extends downward to form a protrusion 99, and the top of the locking block 92 is obliquely cut to form a notch 98 that mates with the protrusion 99. Based on this, when the locking block 92 is engaged with the bottom of the ear block 94, the notch 98 can fit against the protrusion 99, so as to ensure a stable engagement between the locking block 92 and the ear block 94.

[0038] Furthermore, such as Figures 7-9 As shown, one side of the protrusion 99 extends outward to form a limiting block 96, and a limiting groove 97 for the limiting block 96 to be inserted is provided on the inner wall of the notch 98. Based on this, the protrusion 99 and the notch 98 can be limited, thereby facilitating the stable engagement of the locking block 92 with the bottom of the ear block 94, and realizing a stable connection between the box cover 2 and the settling box 1.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
