Description

Technical Field

[0001] This utility model relates to the field of stirring equipment technology, specifically to a three-way mixing flow assembly on the inner side of a reaction vessel wall. Background Technology

[0002] In chemical production, stirring is an important process widely used in the mixing, dispersion, extraction and crystallization of materials. Currently, anchor-type, paddle-type and folding-blade turbine-type stirrers are widely used in precipitation crystallization reactors. The axial flow generated during stirring can promote the mixing and reaction of suspended materials. However, the circumferential flow generated during stirring affects the degree of mixing of materials. In order to reduce the circumferential flow during stirring, baffles are usually installed on the inner wall of the reactor.

[0003] Patent document CN221267773U discloses a baffle structure for a mixing vessel that enhances mixing effect through self-impact diversion. The structure includes a mixing vessel tank, a stirring shaft, an arc-shaped baffle, a guide fluid, and a diversion channel. The inner wall of the mixing vessel tank is integrally formed with an inner mixing vessel body. The stirring shaft is located in the middle of the inner side of the mixing vessel tank, and a stirring paddle is fixedly installed at the bottom end of the stirring shaft. The rotation direction of both the stirring shaft and the stirring paddle is counterclockwise.

[0004] The existing technology and the above-mentioned devices all have the following shortcomings: the current baffle has a large load and high energy consumption, and because the liquid can easily bypass the baffle and continue to flow in the circumferential direction, the effect of suppressing the circumferential flow is not obvious. Utility Model Content

[0005] The technical problem solved by this utility model is: (1) The current baffles have a large load and high energy consumption; (2) The current baffle structure does not have a significant effect on suppressing circumferential flow.

[0006] The objective of this utility model can be achieved through the following technical solution: a three-dimensional mixing flow assembly on the inner side of a reactor wall, comprising a first baffle installed on the inner side wall of the reactor, wherein a plurality of first baffles are arranged in a multi-layered annular array and uniformly distributed on the inner side wall of the reactor, and a second baffle is provided between each two adjacent layers of first baffles, the second baffles being fixedly installed on the inner side wall of the reactor, wherein a plurality of second baffles are arranged in a annular array and uniformly distributed, the flow-facing surfaces of the first baffles and the second baffles are both arc surfaces, and the radius of the inner side wall of the reactor is R.

[0007] Preferably, the first baffle includes a first mounting base, one side of which matches the shape of the inner wall of the reactor, and the other side of the first mounting base is fixedly connected to a first guide plate.

[0008] Preferably, the upstream face of the first deflector is arc-shaped, and the central angle α corresponding to the arc of the upstream face of the first deflector is between 90 degrees and 180 degrees.

[0009] Preferably, the height of both sides of the first deflector is consistent with the height of the first mounting seat.

[0010] Preferably, when the radius of the arc of the upstream face of the first deflector is r, then R / 30 < r < R / 20.

[0011] Preferably, when the height of the first mounting seat is h, then 2R / 15 < h < R / 5.

[0012] Preferably, a first embedded rod is fixedly connected to the middle of each of two sides of the first mounting seat, a plurality of first bolt holes arranged in parallel at equal intervals are formed in the middle of the first embedded rod, first clamping blocks are installed at both ends of the first embedded rod, a first right guide embedded plate is installed on the first embedded rod close to the upstream face of the first deflector, and a first left guide embedded plate is installed on the first embedded rod far away from the upstream face of the first deflector.

[0013] Preferably, the second baffle comprises a second mounting seat, one side of the second mounting seat matches the shape of the inner side wall of the reaction kettle, and the other side of the second mounting seat is fixedly connected with a second deflector.

[0014] Preferably, the upstream face of the second deflector is arc-shaped, the central angle b corresponding to the arc of the upstream face of the second deflector is between 90 degrees and 180 degrees, the height of the side of the second deflector close to the inner side wall of the reaction kettle is consistent with the height of the second mounting seat, the height of the side of the second deflector far away from the inner side wall of the reaction kettle is at least twice the height of the second mounting seat, when the radius of the arc of the upstream face of the second deflector is t and the height of the second mounting seat is g, then R / 30 < t < R / 20 and R / 15 < g < R / 10.

[0015] Preferably, a second embedded rod is fixedly connected to the middle of each of two sides of the second mounting seat, a plurality of second bolt holes arranged in parallel at equal intervals are formed in the middle of the second embedded rod, second clamping blocks are installed at both ends of the second embedded rod, a second right guide embedded plate is installed on the second embedded rod close to the upstream face of the second deflector, and a second left guide embedded plate is installed on the second embedded rod far away from the upstream face of the second deflector.

[0016] The beneficial effects of the present utility model are: (1) During operation, through the arc upstream structure of the first baffle and the second baffle, eddy currents are generated in the arc surfaces of the first baffle and the second baffle. Through the blocking of the first baffle and the second baffle, the circumferential flow of materials is reduced, so that after the originally circumferentially flowing materials impact the first baffle and the second baffle, three streams of fluids in different directions: upward, downward and pointing to the axis of the reaction kettle are generated, which collide with the materials still in circumferential flow around, thereby suppressing circumferential flow to the greatest extent and increasing the stirring uniformity of the materials; (2) During operation, different first guide plates are selected according to the viscosity of the material and the stirring requirements. Different states of fluid are generated by different sizes of central angle α to suppress circumferential flow and improve stirring effect. When the viscosity of the material is low, the first guide plate with a central angle α between 90 degrees and 135 degrees is selected. In this way, while generating vortices, a jet with a flow direction pointing towards the center of the reactor is generated, forming an impact on the material. Compared with traditional baffles, the stirring torque and stirring power can be reduced, achieving the effect of energy saving. When the viscosity of the material is high, the first guide plate with a central angle α between 135 degrees and 180 degrees is selected, so that vortices are generated in the arc surface of the first baffle. This makes the material that originally flowed circumferentially present a micro-mixing environment of impact and vortex in the local environment. This makes the material near the inner wall of the reactor generate multiple micro-mixing environments in the area where the first baffle and the second baffle are located, further suppressing circumferential flow and improving the stirring uniformity of the material. (3) During operation, different first guide plates are selected according to the viscosity of the material and the stirring requirements. Different vortices are generated by the second guide plates with different central angles b and different heights to suppress circumferential flow and improve the stirring effect. As the viscosity of the material increases, the second guide plate is continuously replaced so that the height of the side away from the inner wall of the reactor is continuously increased based on twice the height of the second mounting base. This allows materials of different viscosities to stably generate rising and falling vortices, thereby generating vortices in three directions, which impact the material vortices generated by the first guide plate. This causes vortices to be generated in the arc surface of the second baffle, so that the material that originally flowed circumferentially is in a micro-mixing environment of impact and vortex in the local environment. This causes the material near the inner wall of the reactor to generate multiple micro-mixing environments in the area where the first baffle and the second baffle are located, further suppressing circumferential flow and improving the stirring uniformity of the material.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0020] Please see Figure 1-5 As shown: A three-dimensional mixing flow assembly on the inner side of a reactor wall includes a first baffle 100 installed on the inner side wall of the reactor. The first baffle 100 is provided in a multi-layered annular array and is evenly distributed on the inner side wall of the reactor. A second baffle 200 is provided between each two adjacent layers of the first baffle 100. The second baffle 200 is fixedly installed on the inner side wall of the reactor. Each layer of the second baffle 200 is provided in a multi-layered annular array and is evenly distributed. The flow-facing surfaces of the first baffle 100 and the second baffle 200 are both arc surfaces. When materials are stirred in a reactor, they will inevitably move around the reactor's axis. In this embodiment, the circumferential flow of materials is reduced by the obstruction of the first baffle 100 and the second baffle 200. This causes the materials that were originally flowing circumferentially to collide with the first baffle 100 and the second baffle 200, generating three different streams of fluid in different directions: upward, downward, and towards the reactor's axis. These streams collide with the surrounding materials that are still flowing circumferentially, thereby suppressing circumferential flow to the greatest extent and increasing the uniformity of material mixing. Furthermore, the arc-shaped flow-facing structure of the first baffle 100 and the second baffle 200 generates vortices within their arc surfaces, causing the material, which was originally flowing circumferentially, to form a micro-mixing environment of impact and vortex in the local environment. This results in multiple micro-mixing environments being generated in the area where the material near the inner wall of the reactor is located, further suppressing circumferential flow and improving the uniformity of material mixing.

[0021] The first baffle 100 includes a first mounting seat 101, one side of the first mounting seat 101 matches the shape of the inner side wall of the reaction kettle, the other side of the first mounting seat 101 is fixedly connected with a first flow guide plate 102, the flow-facing surface of the first flow guide plate 102 is arc-shaped, the central angle α corresponding to the arc of the flow-facing surface of the first flow guide plate 102 is between 90 degrees and 180 degrees, the height of both sides of the first flow guide plate 102 is consistent with the height of the first mounting seat 101, the radius of the inner side wall of the reaction kettle is R, the arc radius of the flow-facing surface of the first flow guide plate 102 is r, and the height of the first mounting seat 101 is h, then R / 30 < r < R / 20 and 2R / 15 < h < R / 5; When the present embodiment works, different first flow guide plates 102 are selected according to the viscosity of materials and stirring requirements, and fluids in different states are generated through different central angles α to suppress circumferential flow and improve the stirring effect. When the viscosity of materials is low, the first flow guide plate 102 with a central angle α between 90 degrees and 135 degrees is selected, so that while generating eddy currents, a jet flow directed to the axis of the reaction kettle is generated, forming an impact on the materials. Compared with traditional baffles, the stirring torque and stirring power can be reduced, achieving the effect of energy saving. When the viscosity of materials is high, the first flow guide plate 102 with a central angle α between 135 degrees and 180 degrees is selected, so as to increase the generation of eddy currents and local micro-mixing environments, promote the collision and mixing of viscous materials, and improve the stirring uniformity.

[0022] First embedded rods 103 are fixedly connected to the middle of both sides of the first mounting seat 101, a plurality of first bolt holes 105 arranged at equal intervals side by side are opened in the middle of the first embedded rod 103, first clamping blocks 104 are installed at both ends of the first embedded rod 103, a first right flow guide embedded plate 107 is installed on the first embedded rod 103 close to the flow-facing surface of the first flow guide plate 102, and a first left flow guide embedded plate 106 is installed on the first embedded rod 103 far away from the flow-facing surface of the first flow guide plate 102; When the present embodiment works, the first right flow guide embedded plate 107 cooperates with the flow-facing surface of the first flow guide plate 102 to guide the materials, reducing the kinetic energy loss of the materials during the change of movement direction, and the first left flow guide embedded plate 106 reduces the generation of turbulence on the back-flow surface of the first flow guide plate 102, thereby improving the stirring uniformity.

[0023] The second baffle 200 comprises a second mounting base 201. One side of the second mounting base 201 matches the shape of the inner side wall of the reaction kettle, and the other side of the second mounting base 201 is fixedly connected with a second flow guide plate 202. The upstream face of the second flow guide plate 202 is arc-shaped, and the central angle b corresponding to the arc of the upstream face of the second flow guide plate 202 is between 90 degrees and 180 degrees. The height of the side of the second flow guide plate 202 close to the inner side wall of the reaction kettle is consistent with the height of the second mounting base 201, and the height of the side of the second flow guide plate 202 away from the inner side wall of the reaction kettle is at least twice the height of the second mounting base 201. Wherein the arc radius of the upstream face of the second flow guide plate 202 is t, and the height of the second mounting base 201 is g, then R / 30 < t < R / 20 and R / 15 < g < R / 10; Second insertion rods 203 are fixedly connected to the middle parts of both sides of the second mounting base 201, a plurality of second bolt holes 205 arranged in equal distance and side by side are formed in the middle part of each second insertion rod 203, second clamping blocks 204 are installed at both ends of each second insertion rod 203, a second right flow guide insertion plate 207 is installed on the second insertion rod 203 close to the upstream face of the second flow guide plate 202, and a second left flow guide insertion plate 206 is installed on the second insertion rod 203 away from the upstream face of the second flow guide plate 202; When the present embodiment works, different first flow guide plates 102 are selected according to the viscosity of materials and stirring requirements, and eddy currents in different states are generated through different central angles b and second flow guide plates 202 with different heights to suppress circumferential flow and improve the stirring effect. As the viscosity of materials increases, the second flow guide plate 202 is continuously replaced so that the height of the side thereof away from the inner side wall of the reaction kettle is continuously increased on the basis of twice the height of the second mounting base 201, so that materials with different viscosities can stably generate upward and downward eddy currents, thereby generating eddy currents in three directions, which forms an impact on the material eddy current generated by the first flow guide plate 102, thereby increasing the generation of eddy currents and the generation of local micro-mixing environments, promoting the impact and mixing of viscous materials, and improving the stirring uniformity.

[0024] When the utility model is used, through the arc upstream face structure of the first baffle 100 and the second baffle 200, eddy currents are generated in the arc surfaces of the first baffle 100 and the second baffle 200. Through the blocking of the first baffle 100 and the second baffle 200, the circumferential flow of materials is reduced, so that after the originally circumferentially flowing materials impact the first baffle 100 and the second baffle 200, three strands of fluid in different directions upward, downward and pointing to the axis of the reaction kettle are generated, which collide with the materials still in circumferential flow around, thereby suppressing circumferential flow to the greatest extent and increasing the stirring uniformity of the materials; During operation, different first guide plates 102 are selected according to the viscosity of the material and the stirring requirements. Different central angles α are used to generate fluids in different states to suppress circumferential flow and improve the stirring effect. When the viscosity of the material is low, a first guide plate 102 with a central angle α between 90 and 135 degrees is selected. This generates vortices and jets that flow towards the axis of the reactor, creating an impact on the material. Compared with traditional baffles, this can reduce stirring torque and stirring power, achieving energy saving. When the viscosity of the material is high, a first guide plate 102 with a central angle α between 135 and 180 degrees is selected. This generates vortices within the arc surface of the first baffle 100, causing the material that originally flowed circumferentially to form a micro-mixing environment of impact and vortex in the local environment. This creates multiple micro-mixing environments in the area where the first baffle 100 and the second baffle 200 are located, further suppressing circumferential flow and improving the uniformity of material stirring. During operation, different first guide plates 102 are selected according to the viscosity of the material and the stirring requirements. Different vortices are generated by using second guide plates 202 of different sizes and heights to suppress circumferential flow and improve the stirring effect. As the viscosity of the material increases, the second guide plate 202 is continuously replaced so that the height of the side away from the inner wall of the reactor is continuously increased from twice the height of the second mounting base 201. This allows materials of different viscosities to stably generate rising and falling vortices, resulting in vortices in three directions. These vortices impact the material vortices generated by the first guide plate 102, causing vortices to be generated within the arc surface of the second baffle 200. This creates a micro-mixing environment of impact and vortex in the local environment, where the material that was originally flowing circumferentially is located. As a result, multiple micro-mixing environments are generated in the area where the first baffle 100 and the second baffle 200 are located near the inner wall of the reactor, further suppressing circumferential flow and improving the uniformity of material stirring.

[0025] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
