Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to a stirred crystallization reactor. Background Technology

[0002] According to the patent document with publication number CN220424589U, the patent document improves crystallization efficiency by setting up a stirring mechanism and a vortex mechanism, in which the vortex impeller rotates synchronously while the stirring paddle rotates on its own.

[0003] The stirring mechanism in this patent document has a fixed stirring paddle that rotates in one place, and the vortex impeller rotates close to the inner wall of the reactor. Therefore, the stirring mechanism only has a strong stirring effect on the middle position and the position near the inner wall of the reactor, and the stirring of raw materials in other positions is insufficient. Utility Model Content

[0004] The purpose of this invention is to provide a stirred crystallization reactor in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A stirred crystallization reactor includes a reactor, a support frame inside the reactor, and a stirring mechanism disposed inside the reactor.

[0007] The stirring mechanism includes a motor, which is mounted on the upper side of the reactor. A rotating shaft is fixed to the output part of the motor that extends into the reactor. A first connecting piece is fixed to one end of the rotating shaft near the motor output part. A stirring rod is rotatably connected to the end of the first connecting piece away from the motor output part. A movable sleeve is rotatably connected to one end of the stirring rod near the first connecting piece. A second connecting piece is fixed in the middle of the movable sleeve. The other end of the second connecting piece is fixed to the rotating shaft. A spur gear is fixed to the position of the stirring rod near the movable sleeve. The spur gear meshes with a gear ring, which is fixed to a bracket. A stirring blade is circumferentially fixed to the lower end of the stirring rod.

[0008] Preferably, a feeding port is provided on the side of the top of the reactor away from the support, and a closed port is provided on the front side of the reactor.

[0009] Preferred configuration: The stirring rod and the movable sleeve are inclined.

[0010] Preferably, the top of the support is fixed to the top of the reactor.

[0011] Preferably, the bottom circumference of the reactor is provided with five feet, and the distance between the feet is equal.

[0012] Preferably, the teeth on the gear ring mesh with the spur gear.

[0013] The advantages compared to existing technologies are as follows:

[0014] 1. By setting up a stirring mechanism with an inclined rotating stirring rod, the stirring rod can be tilted and rotated over a large range to stir the raw materials;

[0015] 2. By setting up gears and gear rings, the stirring rod can rotate on its own axis while revolving around the central axis, thus achieving simultaneous stirring of raw materials by the stirring rod revolving around the central axis and rotating on its own axis. Attached Figure Description

[0027] like Figures 1-5 As shown, a stirred crystallization reactor includes a reactor 2, a support 1 inside the reactor 2, and a stirring mechanism 5 inside the reactor 2.

[0028] In this embodiment: the stirring mechanism 5 includes a motor 51, which is mounted on the upper side of the reaction vessel 2. A rotating shaft 52 is fixed to the output section of the motor 51, which extends into the reaction vessel 2. A first connecting member 53 is fixed to one end of the rotating shaft 52 near the output section of the motor 51. A stirring rod 58 is rotatably connected to the end of the first connecting member 53 away from the output section of the motor 51. A movable sleeve 54 is rotatably connected to one end of the stirring rod 58 near the first connecting member 53. A second connecting member 55 is fixed in the middle of the movable sleeve 54. The other end of the second connecting member 55 is fixed to the rotating shaft 52. A spur gear 56 is fixed near the movable sleeve 54 on the rod 58. The spur gear 56 meshes with a gear ring 57, which is fixed on the bracket 1. A stirring blade 59 is circumferentially fixed at the lower end of the stirring rod 58. The output of the motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the first connecting member 53 and the second connecting member 55 to rotate. The first connecting member 53 and the second connecting member 55 together drive the movable sleeve 54 and the stirring rod 58 to revolve around the rotating shaft 52 as the center of rotation. The spur gear 56 meshes with the gear ring 57, thereby causing the spur gear 56 to drive the stirring rod 58 to rotate itself.

[0029] In this embodiment: a feeding port 4 is provided on the top side of the reactor 2 away from the support 1, and a closed port is provided on the front side of the reactor 2. The raw materials are fed into the reactor 2 through the feeding port 4, and the raw materials are taken out through the closed port after the reaction.

[0030] In this embodiment, the stirring rod 58 and the movable sleeve 54 are inclined to achieve a wide range of agitation of the raw materials when the stirring rod 58 revolves.

[0031] In this embodiment: the top of the bracket 1 is fixed to the top of the reactor 2. The bracket 1 located inside the reactor 2 provides support for the entire stirring mechanism 5, so that the stirring mechanism 5 is located inside the reactor 2, ensuring the sealing of the reactor 2.

[0032] In this embodiment, five feet 3 are provided around the bottom circumference of the reactor 2. The feet 3 are evenly spaced and the five evenly spaced feet 3 stably support the reactor 2 to prevent the reactor 2 from shaking.

[0033] In this embodiment, the teeth on the gear ring 57 mesh with the spur gear 56, so that the teeth on the gear ring 57 can smoothly drive the spur gear 56 to rotate, thereby realizing the rotation of the stirring rod 58 driven by the spur gear 56.

[0034] Working principle: Raw materials are fed into the reactor 2 through the feed port 4. The motor 51 is started, and the output of the motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the first connecting piece 53 and the second connecting piece 55 to rotate. The first connecting piece 53 and the second connecting piece 55 together drive the movable sleeve 54 and the stirring rod 58 to revolve around the rotating shaft 52 as the center of rotation, so that the stirring rod 58 can stir the raw materials in the reactor 2. The spur gear 56 meshes with the gear ring 57, so that the spur gear 56 drives the stirring rod 58 to rotate itself, so that the stirring rod 58 drives the stirring blade 59 to rotate, so as to achieve the rotational stirring of the raw materials. Through the revolution and rotational stirring of the raw materials in the reactor 2 by the stirring rod 58, the crystallization efficiency of the raw materials is accelerated.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
