[0006] Furthermore, the plurality of blocking protrusions are arranged at equal intervals along the circumference of the first flow-retarding plate and form a plurality of annular structures around the axis of the first flow-retarding plate. An overflow gap is provided between adjacent blocking protrusions in each annular structure, and the blocking protrusions in adjacent annular structures are staggered.

[0007] Furthermore, the plurality of baffle rings are coaxially arranged with the second flow deflector, and the diameters of the plurality of baffle rings increase sequentially; the baffle and the second flow deflector are integrally formed.

[0008] Furthermore, there are several second drainage holes, which are evenly spaced along the circumferential direction of the corresponding flow-blocking ring.

[0009] Furthermore, the first, second, and third flow-damping plates are coaxially arranged with the fixed tank body, and the bottom outer diameters of the first, second, and third flow-damping plates increase sequentially. A contact gap is provided between the outer peripheral edge of the third flow-damping plate and the inner wall of the fixed tank body, and the width of the contact gap is smaller than the diameter of the droplet.

[0010] Furthermore, the feeding assembly includes a vertical feeding pipe and a horizontal feeding pipe. The vertical feeding pipe is fixedly connected to the fixed tank body, and its bottom end longitudinally penetrates the top end wall of the fixed tank body. The bottom end of the vertical feeding pipe is also fixedly connected to the slow-flow component. The horizontal feeding pipe is inclined with one end higher than the other. The lower end of the horizontal feeding pipe passes through the side wall of the fixed tank body and the side wall of the vertical feeding pipe in sequence, and then connects to the interior of the vertical feeding pipe. Control valves are provided at the top of the vertical feeding pipe and at the higher end of the horizontal feeding pipe.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are:

[0015] This invention employs a flow-slowing assembly composed of a first flow-slowing plate, a second flow-slowing plate, and a third flow-slowing plate arranged sequentially from top to bottom. When liquid reactants are fed into the feeding assembly, the liquid reactants fall onto the first flow-slowing plate. The liquid reactants flow along the conical inclined surface of the first flow-slowing plate and are diverted by the blocking protrusions. A portion of the liquid reactants flows along the flow gap between adjacent blocking protrusions to the edge of the first flow-slowing plate and falls onto the second flow-slowing plate. The remaining portion is intercepted by the blocking protrusions and flows through the first drainage hole onto the second flow-slowing plate. The diverted liquid reactants then flow along the conical inclined surface of the second flow-slowing plate, where the baffle rings act as a buffer. The system achieves a slow-flow effect on the liquid reactants. After slowing, the liquid reactants fall from the edge of the second slow-flow plate or the second inlet hole onto the conical inclined surface of the third slow-flow plate. The liquid reactants flow along the conical inclined surface of the third slow-flow plate and are completely dispersed. Finally, they contact the inner wall of the fixed tank from the edge of the third slow-flow plate and flow down the inner wall of the fixed tank, achieving a slow mixing and reaction operation with other materials in the fixed tank. This slow-flow component disperses the liquid reactants while achieving a slow-flow effect, giving them a larger contact area with other materials in the fixed tank, which can effectively improve the reaction rate of the reactor. This reactor has a simple structure, low production cost, and good slow-flow effect, and has great market potential. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this embodiment discloses a novel reactor structure, including a fixed tank 4. A liquid outlet 401 is provided on one side of the bottom end of the fixed tank 4. A plug 402 for controlling the opening and closing state of the liquid outlet 401 is provided inside the liquid outlet 401. A stirring assembly is provided inside the fixed tank 4. A feeding assembly is provided at the top of the fixed tank 4. A flow-slowing assembly for dispersing and slowing down the liquid material is provided below the feeding assembly.

[0023] The stirring assembly includes a fixed motor 5 and stirring blades 7. The fixed motor 5 is fixedly connected to the center of the bottom end of the fixed tank 4. The output shaft 6 of the fixed motor 5 passes through the bottom end wall of the fixed tank 4 and extends into the fixed tank 4. The stirring blades 7 are located inside the fixed tank 4 and are fixedly arranged around the outer periphery of the output shaft 6 of the fixed motor 5.

[0024] The flow-regulating assembly includes a first flow-regulating plate 1, a second flow-regulating plate 2, and a third flow-regulating plate 3. All three plates are cone-shaped with a high center and low edges, arranged sequentially from top to bottom. Each plate is fixedly connected to the feeding assembly. The upper surface of the first flow-regulating plate 1 has several uniformly arranged blocking protrusions 101, each with a curved arc structure. The opening of the curved arc structure faces the center of the first flow-regulating plate 1, and the bottom of the curved arc structure has a first longitudinally penetrating flow-guiding hole 102. The upper surface of the second flow-regulating plate 2 has several uniformly arranged baffle rings 201, each with a second longitudinally penetrating flow-guiding hole 202 on the side closest to the center of the second flow-regulating plate 2.

[0025] The plurality of blocking protrusions 101 are arranged at equal intervals along the circumference of the first flow buffer 1 and form a plurality of annular structures around the axis of the first flow buffer 1. A flow gap 103 is provided between adjacent blocking protrusions 101 in each annular structure. The blocking protrusions 101 in adjacent annular structures are staggered to improve the interception effect of the blocking protrusions 101 on liquid reactants.

[0026] The plurality of baffle rings 201 are coaxially arranged with the second flow-retardant plate 2, and the diameters of the plurality of baffle rings 201 increase sequentially; the baffle plate 201 and the second flow-retardant plate 2 are integrally formed. There are a plurality of second flow-guiding holes 202, and the plurality of second flow-guiding holes 202 are equally spaced along the circumferential direction of the corresponding baffle rings 201.

[0027] The first and second drainage holes can prevent liquid reactants from remaining in the space enclosed by the obstruction protrusions or the space blocked by the baffle ring. At the same time, they can achieve the effect of slowing down and diverting the liquid reactants, further improving the effectiveness of this invention.

[0028] The first flow-slowing plate 1, the second flow-slowing plate 2, and the third flow-slowing plate 3 are coaxially arranged with the fixed tank 4. The bottom outer diameter of the first flow-slowing plate 1, the second flow-slowing plate 2, and the third flow-slowing plate 3 increases sequentially. A contact gap 301 is provided between the outer peripheral edge of the third flow-slowing plate 3 and the inner wall of the fixed tank 4. The width of the contact gap 301 is smaller than the droplet diameter of the liquid material.

[0029] The liquid reactant flowing down from the edge of the third buffer plate will come into contact with the inner wall of the fixed tank at the contact gap and flow down along the inner wall of the fixed tank. During its flow, it needs to overcome the friction of the inner wall of the fixed tank, thereby further reducing the addition speed of the liquid reactant and further improving the addition effect of the liquid reactant.

[0030] The feeding assembly includes a vertical feeding pipe 8 and a horizontal feeding pipe 9. The vertical feeding pipe 8 is fixedly connected to the fixed tank 4. The bottom end of the vertical feeding pipe 8 longitudinally penetrates the top end wall of the fixed tank 4, and the bottom end of the vertical feeding pipe 8 is fixedly connected to the slow-flow component. The horizontal feeding pipe 9 is inclined with one end higher and the other end lower. The lower end of the horizontal feeding pipe 9 passes through the side wall of the fixed tank 4 and the side wall of the vertical feeding pipe 8 in sequence and then connects to the interior of the vertical feeding pipe 8. A control valve 801 is provided at the top of the vertical feeding pipe 8 and at the higher end of the horizontal feeding pipe 9.

[0031] The vertical feed pipe 8 is coaxially arranged with the fixed tank 4. A mounting bracket 10 is fixedly connected to the inner wall of the bottom end of the vertical feed pipe 8. A central shaft 11 is fixedly connected to the center of the mounting bracket 10. The central shaft 11 is coaxially arranged with the first flow buffer 1, the second flow buffer 2, and the third flow buffer 3. The bottom end of the central shaft 11 passes through the first flow buffer 1 and the second flow buffer 2 in sequence and is fixedly connected to the top end of the third flow buffer 3. The side wall of the central shaft 11 is fixedly connected to the first flow buffer 1 and the second flow buffer 2.

[0032] The combined design of the vertical and horizontal feed pipes allows users to choose to feed from the top or side of the fixed tank according to their needs, improving the convenience of feeding operations in the reactor.

[0033] This invention employs a flow-slowing assembly composed of a first flow-slowing plate, a second flow-slowing plate, and a third flow-slowing plate arranged sequentially from top to bottom. When liquid reactants are fed into the feeding assembly, the liquid reactants fall onto the first flow-slowing plate. The liquid reactants flow along the conical inclined surface of the first flow-slowing plate and are diverted by the blocking protrusions. A portion of the liquid reactants flows along the flow gap between adjacent blocking protrusions to the edge of the first flow-slowing plate and falls onto the second flow-slowing plate. The remaining portion is intercepted by the blocking protrusions and flows through the first drainage hole onto the second flow-slowing plate. The diverted liquid reactants then flow along the conical inclined surface of the second flow-slowing plate, where the baffle rings act as a buffer. The system achieves a slow-flow effect on the liquid reactants. After slowing, the liquid reactants fall from the edge of the second slow-flow plate or the second inlet hole onto the conical inclined surface of the third slow-flow plate. The liquid reactants flow along the conical inclined surface of the third slow-flow plate and are completely dispersed. Finally, they contact the inner wall of the fixed tank from the edge of the third slow-flow plate and flow down the inner wall of the fixed tank, achieving a slow mixing and reaction operation with other materials in the fixed tank. This slow-flow component disperses the liquid reactants while achieving a slow-flow effect, giving them a larger contact area with other materials in the fixed tank, which can effectively improve the reaction rate of the reactor. This reactor has a simple structure, low production cost, and good slow-flow effect, and has great market potential.
