Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a stirred reaction vessel. Background Technology

[0002] In the fields of chemical, pharmaceutical, food, and new materials production, stirred tank reactors are one of the core production equipment, mainly used to achieve mixing and reaction between materials. Good stirring effect is directly related to the purity, yield, and quality stability of the product.

[0003] Traditional stirred tank reactors typically rely on an electric motor to drive a stirring shaft within the reactor vessel, with impellers fixed to the shaft. However, existing stirring structures still present the following pressing problems in practical applications: (1) When a conventional rigid agitator rotates, it mainly drives the fluid in direct contact with it to move. For high-viscosity materials, this can lead to uneven mixing. At the same time, due to the fixed stirring trajectory, dead zones are easily formed inside the vessel, especially in the area near the inner wall.

[0004] (2) Traditional fixed agitators usually do not have a self-cleaning function and cannot effectively scrape off the residue on the inner wall of the vessel, which increases the difficulty of cleaning and the cost of downtime maintenance. Utility Model Content

[0005] In order to solve the technical problems existing in the background art, the present invention provides a stirred reaction vessel, which can efficiently agitate and mix the materials in the vessel, and also has the function of scraping and cleaning the residual materials on the inner wall of the vessel.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A stirred reactor, comprising: The vessel body; The stirring assembly is rotatably installed inside the vessel body; The stirring assembly includes: Central axis; The side shaft is located on the outer periphery of the central shaft; The movable block is set on the side shaft and can rotate freely.

[0007] Furthermore, the side shaft and the central shaft are fixedly connected by a connecting plate at the bottom.

[0008] Furthermore, the activity blocks include: The connecting part is rotatably mounted on the side shaft; The swinging part extends outward along the radial direction of the connecting part.

[0009] Furthermore, the swing section has a side groove.

[0010] Furthermore, the side grooves are located on the upper and lower sides of the swing section.

[0011] Furthermore, the connecting part has a rotating hole, which can be freely rotated and fitted onto the side shaft.

[0012] Furthermore, the movable blocks are made of resin.

[0013] Furthermore, the vessel body is made of enamel.

[0014] Furthermore, the side wall of the vessel body has a cavity.

[0015] The beneficial effects of this utility model are: (1) By setting a freely rotatable movable block on the side shaft, during stirring, the movable block rotates around the side shaft and revolves around the central axis with the side shaft under the combined action of centrifugal force and material resistance, thus creating multidimensional disturbance to the material in the vessel. This effectively eliminates the dead zone of stirring and greatly improves the uniformity of mixing.

[0016] (2) The swinging part extends radially outward along the connecting part, expanding the stirring coverage area. At the same time, the autonomous rotation of the moving block avoids material retention on its surface, reducing the risk of material coking or solidification, and giving the stirring component a certain self-cleaning function.

[0017] (3) Since the movable block is rotatably mounted on the side shaft, when the swinging part touches the attached material on the inner wall of the vessel, it can achieve a cleaning effect similar to a scraper, effectively removing residual material from the inner wall.

[0018] (4) By opening side grooves on the side of the movable block to embed the card plate, a rigid connection of multiple independent movable blocks can be achieved, enabling multiple movable blocks to rotate synchronously as a unified whole, effectively changing the rotational inertia and turbulence pattern of a single movable block. The combination method and distribution density of the movable blocks can be flexibly adjusted according to the material characteristics and process stage requirements, realizing active control of stirring intensity and flow field, and significantly improving mixing efficiency and uniformity.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a stirred reactor includes a reactor body 1. In a specific embodiment, the reactor body 1 is made of enamel, and a cavity 11 is formed in the side wall of the reactor body 1. The cavity 11 has a heat preservation function. A stirring assembly 2 is rotatably disposed inside the reactor body 1. The connection between the stirring assembly 2 and the reactor body 1 is existing technology, such as using a motor drive.

[0024] like Figure 2 As shown, the specific structure of the stirring assembly 2 includes a central shaft 21. Side shafts 23 are evenly distributed around the outer periphery of the central shaft 21. Movable blocks 24 are rotatably mounted on the side shafts 23. During stirring, under the combined action of centrifugal force and material resistance, the movable blocks 24 both rotate around the side shafts 23 and revolve around the central shaft 21 with the side shafts 23, thus creating multi-dimensional disturbance to the material inside the vessel 1, effectively eliminating dead zones and significantly improving mixing uniformity.

[0025] The side shaft 23 and the central shaft 21 are fixedly connected by the bottom connecting plate 22. The connecting plate 22 also functions as a stirring paddle.

[0026] like Figure 3 As shown, the movable block 24 is made of resin. The specific structure of the movable block 24 includes a connecting part 241, which is rotatably mounted on the side shaft 23. In a specific embodiment, the connecting part 241 has a rotating hole 243, which is rotatably fitted onto the side shaft 23. The swinging part 242 extends radially outward along the connecting part 241, expanding the stirring coverage area. Simultaneously, the autonomous rotation of the movable block 24 prevents material from remaining on its surface, reducing the risk of material coking or solidification, thus giving the stirring assembly 2 a certain self-cleaning function. Furthermore, since the movable block 24 is rotatably mounted on the side shaft 23, when the swinging part 242 touches the deposits on the inner wall of the vessel 1, it can achieve a cleaning effect similar to a scraper, efficiently removing residual material from the inner wall.

[0027] The swing section 242 has side grooves 244. The side grooves 244 are located on the upper and lower sides of the swing section 242. Adjacent side grooves 244 of adjacent movable blocks 24 can be combined to form a cavity for accommodating a clamping plate. The clamping plate can rigidly connect the independent movable blocks 24, thereby enabling multiple movable blocks 24 to rotate synchronously as a unified whole, effectively changing the rotational inertia and turbulence pattern of a single movable block 24. The combination method and distribution density of the movable blocks can be flexibly adjusted according to the material characteristics and process stage requirements, realizing active control of stirring intensity and flow field, and significantly improving mixing efficiency and uniformity.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
