Description

Technical Field

[0001] The utility model relates to the technical field of veterinary drug production, in particular to a reaction kettle for producing veterinary drug intermediates. Background Art

[0002] Chemically synthesized veterinary drug intermediates are chemical synthesis raw materials that need to be produced in chemical workshops. The production process has high requirements for quality accuracy and can be used for the synthesis of veterinary drugs. The production process of veterinary drug intermediates is usually prepared in a reactor.

[0003] At present, a Chinese patent discloses a reactor for the production of veterinary intermediates (publication number CN215028832U). Through a telescopic cylinder and a motor, stirring paddles at different angles in the reaction box are used to achieve more complete stirring. Secondly, through a push rod and a push plate, the intermediate is prevented from staying in the device, avoiding waste of resources. It is worthy of vigorous promotion.

[0009] Preferably, the surface of the ring seat is embedded with balls distributed in a ring shape, and the balls are slidably connected to the inside of the ring groove, which can reduce the resistance when the disc rotates, thereby reducing the operating burden of the stirring motor.

[0014] The beneficial effects of the utility model are:

[0015] 1. The discharge device can actively push the material out of the reactor body, so that the material can be discharged more stably and quickly, and can simultaneously clean the residual material on the inner wall of the reactor body and the surface of the stirring rod, so that the material can be discharged more thoroughly, thereby improving the utilization rate of the material;

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4 As shown, a reactor for producing veterinary drug intermediates includes: a reactor body 1, a stirrer 2 is fixedly connected to the top of the reactor body 1, and the bottom of the stirrer 2 passes through the interior of the reactor body 1; a discharge device 3, the discharge device 3 is slidably connected to the surface of the stirrer 2, and the top of the discharge device 3 passes through the outside of the reactor body 1.

[0024] like Figure 2 and Figure 3As shown, the discharge device 3 includes a disc 31 slidably connected to the inside of the reactor body 1, the top of the disc 31 is provided with evenly distributed guide rod holes 311, the bottom of the agitator 2 penetrates to the outside of the guide rod holes 311, the top of the disc 31 is provided with an annular groove 312, the inside of the annular groove 312 is slidably connected with a ring seat 32, the top of the ring seat 32 is fixedly connected with a hydraulic cylinder 33 fixedly connected to the reactor body 1, and the top of the hydraulic cylinder 33 penetrates to the outside of the reactor body 1; the number of the hydraulic cylinders 33 is two, and the two hydraulic cylinders 33 are symmetrically distributed on both sides of the agitator 2; the surface of the ring seat 32 is embedded with annularly distributed balls 34, and the balls 34 are slidably connected to the inside of the annular groove 312.

[0025] like Figure 2 and Figure 4 As shown, the agitator 2 includes a stirring motor 21 fixedly connected to the top of the reactor body 1, the output shaft of the stirring motor 21 penetrates into the interior of the reactor body 1, the output shaft of the stirring motor 21 is fixedly connected to a connecting plate 22, the bottom of the connecting plate 22 is fixedly connected to stirring rods 23 evenly distributed and respectively slidably connected to the inside of adjacent guide rod holes 311, the bottom of the stirring rod 23 penetrates to the outside of the guide rod hole 311; the surface of the stirring rod 23 is provided with evenly distributed cross mounting cavities 231, the interior of the cross mounting cavity 231 is fixedly connected with a reinforcing mechanism 24; the reinforcing The mechanism 24 includes a telescopic bag 242 disposed inside the cross mounting cavity 231. The surface of the telescopic bag 242 has four balloons 241 fixedly connected to the cross mounting cavity 231. The four balloons 241 just block the four cross mounting cavities 231. One end of the balloon 241 penetrates the outside of the cross mounting cavity 231. The top and bottom of the telescopic bag 242 are fixedly connected to springs 243 fixedly connected to the cross mounting cavity 231. The spring 243 is a rubber material component. The inside of the balloon 241 and the telescopic bag 242 are filled with a pressurized liquid 244.

[0026] During the rotation of the stirring rod 23, the stirring rod 23 drives the balloon 241 to rotate through the cross mounting cavity 231, and the balloon 241 follows the stirring rod 23 to stir the material, which can increase the contact area between the entire agitator 2 and the material, thereby improving the stirring effect on the material; during the lifting and lowering of the disc 31, the disc 31 squeezes the balloon 241 through the guide rod hole 311, and the balloon 241 retracts into the cross mounting cavity 231, so that the disc 31 can be lifted and lowered normally; while the balloon 241 is squeezed, the balloon 241 squeezes the pressurized liquid 244 inside it into the telescopic bag 242, and the telescopic bag 242 is pressurized and expands, and squeezes the spring 243. When the balloon 241 is separated from the guide rod hole 311, the balloon 241 loses its obstruction, the spring 243 squeezes the telescopic bag 242, and the telescopic bag 242 squeezes the pressurized liquid 244 into the corresponding balloon 241, so that the balloon 241 expands again to ensure that it can function normally during stirring.

[0027] When the utility model is in use, the stirring motor 21 drives the connecting plate 22 to rotate, and the connecting plate 22 drives all the stirring rods 23 to rotate and stir the materials in the reactor body 1, so that the materials inside the reactor body 1 are mixed more fully, thereby accelerating the preparation rate of the veterinary drug intermediate;

[0028] After the staff starts the discharge of the reactor body 1, the staff can control the extension of the hydraulic cylinder 33 according to the demand, and the hydraulic cylinder 33 drives the ring seat 32 to move downward, and the ring seat 32 drives the disc 31 to move downward through the ring groove 312. In the process of moving downward, the disc 31 can not only scrape off the material adhering to the inner wall of the reactor body 1, but also scrape off the material adhering to the surface of the stirring rod 23 through the guide rod hole 311, which can make the material more thoroughly discharged from the reactor body 1, and as the disc 31 gradually approaches the inner bottom wall of the reactor body 1, at this time The distance between the disc 31 and the reactor body 1 is also smaller. At this time, the material between the two is also squeezed, which speeds up the material discharge rate until the disc 31 is tightly fitted with the inner bottom wall of the reactor body 1. Compared with the existing air-assisted discharge method, this method can actively push the material out of the reactor body 1, so that the material can be discharged more stably and quickly, and can simultaneously clean the residual material on the inner wall of the reactor body 1 and the surface of the stirring rod 23, so that the material discharge is more thorough, thereby improving the utilization rate of the material.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
