Description

Technical Field

[0001] This utility model belongs to the field of acylation reactor feeding technology, specifically relating to an anti-clogging feeding device for an acylation reactor. Background Technology

[0002] Acylation is an organic chemical reaction process in which an acyl group is introduced onto carbon, nitrogen, oxygen, or sulfur atoms in an organic compound molecule, thereby altering the physicochemical properties of the compound. Acylation reactors are widely used in acylation reaction equipment in organic synthesis, pharmaceutical manufacturing, and food processing.

[0003] Chinese Patent Application No. CN202022208734.2 discloses an anti-clogging feeding device for an acylation reactor, comprising a reactor body and a reactor lid. The reactor body is equipped with a stirring device, and the reactor lid is equipped with a mounting box, a controller, a bracket, and a hopper. A servo motor is mounted on the mounting box, and the motor shaft of the servo motor is fixedly connected to a turntable via a key. Symmetrically arranged connecting columns are arranged on the turntable, and a first pull rod and a second pull rod are rotatably mounted on the two connecting columns, respectively. Symmetrically arranged feeding heads are arranged on the left and right sides of the reactor lid, and the upper ends of the two feeding heads are respectively connected to a first conveying pipe and a second conveying pipe. The first pull rod is fixedly installed to the first conveying pipe, and the second pull rod is fixedly installed to the second conveying pipe. This device enables the symmetrical soft-structure conveying pipes to reciprocate left and right, allowing the inner cavity of the conveying pipes on both sides to reciprocate and expand automatically, preventing blockage of the granular material in the conveying pipes and greatly improving the feeding efficiency of the acylation reactor. However, the periodic expansion of the soft tube in the conveying pipe of the above-mentioned device requires an additional driving device, which is complex and increases costs. In addition, no matter how the conveying pipe expands, the diameter of the feeding head at the lower end of the conveying pipe remains unchanged. This causes the material to gather at the feeding head more quickly when the conveying pipe expands, increasing the risk of material blockage. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an anti-clogging feeding device for an acylation reactor, which utilizes the stirring spindle to drive the feeding device to rotate eccentrically, thereby improving the anti-clogging effect of the feeding device.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] An anti-clogging feeding device for an acylation reactor includes an acylation reactor body and a stirring shaft. A top cover is fixedly installed on the upper end of the acylation reactor body. The stirring shaft is rotatably connected to the center of the top cover. A mounting bracket is fixedly connected to the top cover, and a drive motor is fixedly connected to the mounting bracket. The drive motor is drively connected to the stirring shaft. A drive gear is fixedly connected to the stirring shaft. Symmetrically arranged feeding devices are rotatably connected to the top cover. Each feeding device includes a rotating bushing with a concentric driven gear and an eccentrically positioned vertically upward feed pipe. The driven gear meshes with the drive gear. The drive motor drives the stirring shaft to rotate, which in turn drives the drive gear to rotate, which in turn drives the driven gear to rotate, thereby causing the two feed pipes to rotate rapidly and eccentrically, preventing clogging of the feed pipes.

[0007] As a further feature of the above solution, a through groove is provided at the center of the upper cover, and rotating grooves are symmetrically provided on both sides of the through groove. The through groove is used to install the drive gear, and the rotating grooves are used to install the feeding device.

[0008] As a further feature of the above solution, the mounting bracket device includes a mounting bracket with auxiliary fixing frames on both sides. The auxiliary fixing frames can improve the strength of the mounting bracket. A mounting groove is opened at the center of the mounting bracket, and feeding pipes are symmetrically arranged on both sides of the mounting groove. The mounting groove is located directly above the through groove and is used to install the drive motor. The feeding pipes are located directly above the rotating groove.

[0009] As a further feature of the above scheme, the rotating bushing is rotatably connected in the rotating groove, the feed pipe is connected downward to the acylation tank body, the upper end of the feed pipe is fixedly connected to a hopper, the upper end of the hopper is fixedly connected to a dustproof cover, the material is fed into the hopper through the feeding pipe, the hopper can guide the material into the feed pipe, and at the same time can avoid interference between the feed pipe and the feeding pipe when the feed pipe rotates eccentrically.

[0010] As a further feature of the above solution, the upper end of the dustproof cover is slidably connected to the lower end face of the mounting bracket to prevent dust from scattering during material feeding.

[0011] This utility model has the following beneficial effects:

[0012] When the stirring shaft rotates and stirs inside the acylation tank, it drives the two rotating bushings to rotate synchronously through the drive gear. Since the feed pipe and the rotating bushings are eccentrically set, the feed pipe rotates eccentrically, and the material collides with the inner wall of the feed pipe during the falling process, which solves the problem of feed pipe blockage. At the same time, the structure is simple and reliable, improving the applicability of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-6 This application will be described in detail with reference to the embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, an anti-clogging feeding device for an acylation reactor includes an acylation reactor tank 1 and a stirring shaft 4. A top cover 2 is fixedly installed on the upper end of the acylation reactor tank 1. The stirring shaft 4 is rotatably connected to the center of the top cover 2. A mounting bracket device 3 is fixedly connected to the top cover 2. A drive motor 5 is fixedly connected to the mounting bracket device 3. The drive motor 5 is connected to the stirring shaft 4. A drive gear 6 is fixedly connected to the stirring shaft 4. A symmetrically arranged feeding device 7 is rotatably connected to the top cover 2. The feeding device 7 includes a rotating bushing 701. A concentric driven gear 702 is provided on the rotating bushing 701. An eccentric vertically upward feed pipe 703 is provided on the rotating bushing 701. The driven gear 702 is meshed with the drive gear 6. The drive motor 5 drives the stirring shaft 4 to rotate. The stirring shaft 4 drives the drive gear 6 to rotate. The drive gear 6 drives the driven gear 702 to rotate, thereby driving the two feed pipes 703 to rotate rapidly and eccentrically, preventing the feed pipes 703 from clogging.

[0023] like Figure 4 As shown, a through groove 201 is opened at the center of the upper cover 2, and rotating grooves 202 are symmetrically opened on both sides of the through groove 201. The through groove 201 is used to install the drive gear 6, and the rotating grooves 202 are used to install the feeding device 7. The mounting bracket device 3 includes a mounting bracket 301. The mounting bracket 301 is provided with auxiliary fixing brackets 302 on both sides. The auxiliary fixing brackets 302 can improve the strength of the mounting bracket 301. The mounting bracket 301 is opened at the center of the mounting groove 301, and feeding pipes 303 are symmetrically provided on both sides of the mounting groove 3011. The mounting groove 3011 is located directly above the through groove 201. The through groove 201 is used to install the drive motor 5, and the feeding pipes 303 are located directly above the rotating groove 202.

[0024] like Figure 5 , Figure 6 As shown, the rotating bushing 701 is rotatably connected in the rotating groove 202. The feed pipe 703 is connected downward to the acylation tank 1. The upper end of the feed pipe 703 is fixedly connected to the hopper 704. The upper end of the hopper 704 is fixedly connected to the dust cover 705. The upper end of the dust cover 705 is slidably connected to the lower end face of the mounting bracket 301 to prevent dust from scattering during feeding. The material is fed into the hopper 704 through the feed pipe 303. The hopper 704 can guide the material into the feed pipe 703 and at the same time prevent the feed pipe 703 from interfering with the feed pipe 303 when rotating eccentrically.

[0025] The working process of this utility model is as follows: When the drive motor 5 drives the stirring shaft 4 to rotate and stir in the acylation tank 1, the drive gear 6 drives the driven gear 702 to rotate, which in turn drives the two feed pipes 703 to rotate eccentrically at high speed. The material is fed into the hopper 704 through the feeding pipe 303. The hopper 704 guides the material into the feeding pipe 703. During the falling process, the material collides with the inner wall of the feeding pipe 703 and falls down, which avoids the feeding pipe 703 from being blocked. The hopper 704 can also prevent the feeding pipe 703 from interfering with the feeding pipe 303 and the dust cover 705 when it rotates eccentrically. The dust cover 705 can prevent the dust generated during feeding from scattering.
