AI Technical Summary
In continuous batch reactors, when solid materials are mixed with liquids, the solids tend to float on the surface of the liquid, leading to material inhomogeneity, especially noticeable in high-viscosity, slurry-like reactions.
The system employs a screw feeder and a feed pipe structure. The feed pipe is composed of multiple sealed sleeves, with inner and outer edges surrounding the discharge port. The length is adjusted by a traction rope, allowing solid materials to directly enter the reactor. Combined with the stirring structure, uniform mixing is achieved.
It effectively reduces the inhomogeneity of highly viscous, slurry-like reactants and improves mixing efficiency.

Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of reaction vessel technology, and more specifically relates to a continuous reactor production device. Background technology:
[0002] In a broad sense, a reaction vessel is a stainless steel container that undergoes physical or chemical reactions. A reaction vessel consists of a vessel body, vessel cover, jacket, stirrer, transmission device, shaft sealing device, support, etc. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-to-high-speed mixing functions required by the process can be achieved.
[0003] A continuous batch reactor is a type of reaction vessel that achieves continuous reaction by simultaneously feeding, stirring, and overflowing. Our company's products require mixing of solids and liquids, and we use a common continuous batch reactor. However, because solids float on the liquid surface, even with a stirring structure, there will still be significant differences in the overall material composition, especially in highly viscous, slurry-like reactions, where this inhomogeneity is more pronounced. Utility Model Content:
[0004] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides a continuous reactor production device;
[0005] The first technical problem to be solved is that the continuous batch reactor is a type of reaction vessel that uses simultaneous feeding, stirring and overflow to achieve continuous reaction. Although there is a stirring structure, the overall material will still have a large degree of heterogeneity because solids will float on the surface of the liquid, especially in highly viscous, slurry-like reactions, where this non-uniformity is more obvious.
[0006] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: the continuous reactor production device includes a reactor body; a feed inlet and a stirring mechanism are provided at the top of the reactor body, a liquid feed inlet is provided at the bottom of the reactor body, and at least one overflow outlet is provided at the upper part of the reactor body; characterized in that:
[0007] The feed inlet is connected to a screw feeder, and the outlet of the screw feeder is connected to a guide pipe. The guide pipe is formed by sealing and connecting a preset number of sleeves, and the guide pipe extends vertically into the interior of the reactor body.
[0008] The sleeve at one end of the feed tube is fixedly connected to the outlet of the screw feeder. The end of the sleeve at the other end of the feed tube is provided with an extension edge. The extension edge extends inward to the inside of the sleeve to form an inner extension edge and extends outward to the outside of the sleeve to form an outer extension edge. The inner extension edge forms the outlet of the feed tube. A traction rope is fixedly provided on the outer extension edge. The traction rope passes through the reactor body and extends to the outside.
[0009] Furthermore, the side wall of the reactor body is fitted with a heating coil.
[0010] Furthermore, the stirring mechanism includes a stirring motor, a stirring rod, and a stirring paddle.
[0011] Furthermore, the inner wall of the reactor body is provided with baffles.
[0012] Furthermore, a drain port is also provided at the bottom of the reactor body.
[0013] Furthermore, the other end of the traction rope is connected to the take-up roller.
[0014] The beneficial effects of this utility model are:
[0015] One advantage of this invention is that it provides a reactor with a screw feeder, and the feed pipe extends vertically into the interior of the reactor body, so that the solid material can be directly inserted into the highly viscous, slurry-like liquid. With the help of the stirring structure, the non-uniformity is greatly reduced.
[0016] One advantage of this invention is that the guide tube is formed by sealing and connecting a preset number of sleeves, with the inner edge of the outermost sleeve forming the outlet of the guide tube, and a traction rope fixedly installed on the outer edge, thereby realizing the depth adjustment of the guide tube.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] The specific embodiment of this utility model: a continuous reactor production device includes a reactor body 2; the top of the reactor body 2 is provided with a feed inlet and a stirring mechanism, the bottom of the reactor body 2 is provided with a liquid feed inlet 8, and the upper part of the reactor body 2 is provided with at least one overflow outlet 4.
[0024] The side wall of the reactor body 2 is fitted with a heating coil 6; the stirring mechanism includes a stirring motor 1, a stirring rod 3 and a stirring paddle 7; the inner wall of the reactor body 2 is provided with a baffle plate 5; and the bottom of the reactor body 2 is also provided with a drain port 9.
[0025] The improvement of this utility model is as follows:
[0026] The feed inlet is connected to the screw feeder 10, and the outlet of the screw feeder 10 is connected to the guide pipe, which is formed by a predetermined number of sleeves 13 sealed together.
[0027] As a preferred embodiment of the present invention, the sealing sleeve structure is a sealing boss. Each level of the sleeve 13 has a sealing boss at both the upper and lower ends. The sealing boss at the upper end of each level of the sleeve 13 extends inward, and the sealing boss at the lower end of each level of the sleeve 13 extends outward. The sealing boss at the upper end of the next level of the sleeve 13 seals against the side wall of the previous level of the sleeve 13 and engages with the sealing boss at the lower end of the previous level of the sleeve 13.
[0028] The feed pipe extends vertically into the interior of the reactor body 2;
[0029] The sleeve 13 at one end of the feed tube is fixedly connected to the outlet of the screw feeder 10. The port of the sleeve 13 at the other end of the feed tube is provided with an extension edge. The extension edge extends to the inside of the sleeve 13 to form an inner extension edge 15 and extends to the outside of the sleeve 13 to form an outer extension edge 16. The inner extension edge 15 surrounds the discharge port 14 of the feed tube. The outer extension edge 16 is fixedly provided with a traction rope 12. The traction rope 12 passes through the reactor body 2 and extends to the outside.
[0030] The other end of the traction rope 12 is connected to the take-up roller 11. As a preferred embodiment of this utility model, the crank handle of the take-up roller 11 can be fixed. The crank handle is used to take up the wire on the take-up roller 11, adjust the length of the traction rope 12, and adjust the adjustable length of the guide tube.
[0031] It should be noted that this utility model is a continuous reactor production device. In specific operation,
[0032] 1. First, turn the crank to rotate the take-up roller 11, adjust the length of the traction rope 12, and adjust the adjustable length of the guide tube;
[0033] 2. A preset amount of liquid is added to the reactor body 2 through the liquid feed port 8. Due to the high viscosity and slurry-like nature of the liquid, the powder is not easily mixed with the slurry by stirring. At this time, the solid material is added to the slurry inside the reactor body 2 through the screw feeder 10. The working principle is as follows:
[0034] The screw feeder 10 generates a pushing force that causes the material to be discharged from the outlet 14. Since the inner edge 15 extends inwards towards the inside of the sleeve 13, forming the outlet 14 of the guide pipe, the extruded material is squeezed by the extrusion force against the inner edge 15, thereby pushing the interconnected sleeves 13 downwards, extending the guide pipe into the slurry inside the reactor body 2.
[0035] In this way, since the feed pipe extends into the slurry inside the reactor body 2, the mixing of materials and slurry is more efficient with the stirring, preventing the slurry from floating on the highly viscous, paste-like liquid.
[0036] At the same time, the depth of the feed tube extending into the slurry can be adjusted under different reaction conditions, such as the material-liquid ratio and reaction temperature.
[0037] 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 claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
