Description

Technical Field

[0001] This invention relates to the field of preparation of benzoxycarbonyl succinimide, specifically to a solution dropping device for preparing benzoxycarbonyl succinimide. Background Technology

[0002] The preparation of benzoxycarbonyl succinimide typically involves multiple chemical reactions, among which solution dropwise addition is a key step. A solution dropwise addition device is required in the preparation process, which focuses on ensuring precise control and uniform mixing of reactants during the dropwise addition process. This device achieves the gradual addition of reactants through dropwise addition.

[0003] In existing technology, the device gradually adds reactants to the reaction vessel by precisely controlling the flow rate and volume of the solution in the dropper to achieve the preparation of benzooxycarbonyl succinimide. However, in actual use, the solution in the dropper is prone to precipitation and particulate matter when the device is used for a long time. As a result, the reactants are not mixed evenly in subsequent dropping processes, which affects the reaction rate and even produces solid particles, thus affecting the preparation effect of benzooxycarbonyl succinimide. Therefore, it is necessary to improve the solution dropping device for the preparation of benzooxycarbonyl succinimide. Utility Model Content

[0007] The stirring assembly includes a fixed plate fixedly connected to the top of the storage tank. A motor is fixedly connected to the front of the fixed plate, and a bevel gear is fixedly connected to the output end of the motor. A rotating rod is fixedly connected to the back of the bevel gear, and an adjusting column is fixedly connected to the back of the rotating rod.

A second bevel gear is rotatably connected to the top of the storage tank, and a stirring frame is fixedly connected to the bottom of the second bevel gear to prevent sedimentation of the solution inside the storage tank.

[0008] Preferably, the second bevel gear meshes with the bottom of the first bevel gear, and the stirring frame is provided with a hole at the corresponding position of the storage tank, and the stirring frame is rotatably connected in the hole, so as to facilitate the synchronous rotation of the stirring frame and the up and down movement of the dial plate.

[0010] Preferably, the filtration assembly includes a filter plate inserted into the storage tank. A sealing ring is fixedly connected to the top and bottom of the filter plate. A locking block is slidably connected inside the storage tank. A spring is fixedly connected between the locking block and the storage tank.

[0011] Preferably, the card block has a groove at the position corresponding to the filter plate, and the card block is inserted into the groove, which facilitates the cleaning and disassembly of the filter plate later.

[0012] Preferably, the closing mechanism includes a limiting sleeve, which is fixedly connected to the bottom of the storage tank.

[0014] Compared with the prior art, the present invention provides a solution dropping device for preparing benzoxycarbonyl succinimide, which has the following beneficial effects:

[0015] 1. This solution dropping device for preparing benzooxycarbonyl succinimide, through a set stirring and filtering mechanism, starts motor one, which drives the dial plate to move downward. At the same time, the second bevel gear drives the stirring frame to rotate, thereby rapidly stirring the solution inside the storage tank. During continuous rotation, it works in conjunction with the dial plate to synchronously drive the dial plate to move up and down, thereby further preventing precipitation of the solution during long periods of stillness. This avoids uneven mixing of reactants during subsequent dropping, thus increasing the reaction rate and preventing any impact on the preparation of benzooxycarbonyl succinimide.

[0016] 2. The solution dripping device for preparing benzooxycarbonyl succinimide has a closing mechanism. By manually rotating the rotating retaining ring, the rotating retaining ring rotates, thereby driving the sliding column to move. The sliding column synchronously drives the sealing plate to move, thereby driving the four sealing plates to move along the guide groove inside the limiting sleeve. This causes the four sealing plates to move inward synchronously, closing the four sealing plates inward, and thus closing the outlet of the storage tank. Attached Figure Description

[0026] Example 1:

[0027] Please see Figure 1-5 This utility model provides a technical solution: a solution dripping device for preparing benzooxycarbonyl succinimide, including a connecting seat 1, a connecting frame 2 fixedly connected to the top of the connecting seat 1, a storage tank 3 fixedly connected to the inner side of the connecting frame 2, a stirring and filtering mechanism 4 provided inside the storage tank 3, a liquid inlet 5 fixedly connected to the bottom of the storage tank 3, a closing mechanism 6 fixedly connected to the bottom of the storage tank 3, a flow controller 7 provided at the bottom of the closing mechanism 6, and a drip outlet 8 provided at the bottom of the flow controller 7;

[0028] The stirring and filtering mechanism 4 includes a stirring component 41 and a filtering component 42, with the filtering component 42 disposed below the stirring component 41;

[0029] The stirring assembly 41 includes a fixed plate 411, which is fixedly connected to the top of the storage tank 3. A motor 412 is fixedly connected to the front of the fixed plate 411. A bevel gear 413 is fixedly connected to the output end of the motor 412. A rotating rod 414 is fixedly connected to the back of the bevel gear 413. An adjusting column 415 is fixedly connected to the back of the rotating rod 414. A rotating frame 416 is movably connected to the outside of the adjusting column 415. A lever 419 is fixedly connected to the bottom of the rotating frame 416. A second bevel gear 417 is rotatably connected to the top of the storage tank 3. A stirring rack 418 is fixedly connected to the bottom of the second bevel gear 417 to prevent sedimentation of the solution inside the storage tank 3.

[0030] Furthermore, the second bevel gear 417 meshes with the bottom of the first bevel gear 413, and the stirring frame 418 is provided with a hole at the corresponding position of the storage tank 3, and the stirring frame 418 is rotatably connected in the hole, so as to synchronously drive the stirring frame 418 to rotate and the lever 419 to rise and fall.

[0031] Furthermore, the lever 419 and the stirring frame 418 are provided with holes at corresponding positions, and the lever 419 is movably connected in the holes. The adjusting column 415 and the rotating frame 416 are provided with grooves at corresponding positions, and the adjusting column 415 is movably connected in the grooves, which facilitates the stable rotation of the stirring frame 418.

[0032] Furthermore, the filter assembly 42 includes a filter plate 421, which is inserted into the storage tank 3. The top and bottom of the filter plate 421 are fixedly connected with sealing rings 422. A locking block 423 is slidably connected inside the storage tank 3. A spring 424 is fixedly connected between the locking block 423 and the storage tank 3. A pull rod 425 is fixedly connected to the front of the filter plate 421 to facilitate the filtration of internal impurities in the solution and improve the effect of subsequent reactions.

[0033] Furthermore, a groove is provided at the corresponding position of the locking block 423 and the filter plate 421, and the locking block 423 is inserted into the groove, which facilitates the cleaning and disassembly of the filter plate 421 later.

[0034] Example 2:

[0035] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the closing mechanism 6 includes a limiting sleeve 61, which is fixedly connected to the bottom of the storage tank 3. A slider 62 is slidably connected to the bottom of the limiting sleeve 61. A sealing plate 63 is fixedly connected to the bottom of the slider 62. A sliding column 64 is fixedly connected to the bottom of the sealing plate 63. A rotating retaining ring 65 is movably connected to the outside of the sliding column 64. A second sealing ring 66 is fixedly connected to the bottom of the rotating retaining ring 65, which facilitates manually closing the outlet of the storage tank 3 when the device is not in use.

[0036] Furthermore, the rotating retaining ring 65 is rotatably connected to the bottom of the limiting sleeve 61, and the flow controller 7 is fixedly connected to the bottom of the limiting sleeve 61, and the sealing ring 66 abuts against the top of the flow controller 7, so as to drive the sealing plate 63 to open or close synchronously.

[0037] In actual operation, when the device is in use, firstly, the motor 412 is started through the set stirring and filtering mechanism 4. The motor 412 drives the bevel gear 413 to rotate, which in turn drives the rotating rod 414 to rotate. The rotating rod 414 then drives the adjusting column 415 to rotate. As the adjusting column 415 rotates, the rotating frame 416 slides along the groove opened inside the stirring frame 418, thereby driving the deflector plate 419 to move downward. At the same time, the bevel gear 413 drives the second bevel gear 417 to rotate, which in turn drives the stirring frame 418 to rotate, thus rapidly stirring the solution inside the storage tank 3. During continuous rotation, it works in conjunction with the deflector plate 419, synchronously driving the deflector plate 419 to move up and down. Before passing through the flow controller 7, the solution passes through the filter plate 4. 21. The solution is rapidly filtered to prevent impurities from entering the reactants. During disassembly, the locking block 423 is manually pulled upwards to completely detach it from the filter plate 421. Then, the filter plate 421 is manually pulled forward to fix it to the storage tank 3, facilitating disassembly and cleaning. When the solution is not in use, the rotating retaining ring 65 is manually rotated through the closing mechanism 6. This rotation causes the sliding column 64 to move, which in turn moves the sealing plate 63. This causes the surrounding sealing plates 63 to move along the guide groove inside the limiting sleeve 61, thus closing the outlet of the storage tank 3.
