Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a reaction apparatus. Background Technology

[0002] The synthesis reaction in the production of rubber accelerators takes place in a reactor. However, in existing technology, solid raw materials are added to the reactor by drawing them in under negative pressure through a sealed, opaque pipe. This not only makes it difficult to add solid raw materials effectively, but also makes it impossible to control the rate of addition during the reaction. Furthermore, it easily leads to uneven reaction, which is detrimental to the reaction process and thus has a significant impact on product quality.

[0003] Chinese utility model patent application CN 214636404 U, published on November 9, 2021, discloses a reaction vessel for producing rubber accelerators. The device includes a support base and a reaction vessel. Supports are symmetrically arranged at both ends of the support base. The reaction vessel is installed between the supports. A heater is installed on the side of the support near the reaction vessel. A feed inlet is located at the top of the side wall of the reaction vessel, and a discharge outlet is located on the side of the reaction vessel near the support base. A solenoid valve is installed between the discharge outlet and the reaction vessel. A rotating shaft is installed inside the reaction vessel. A main gear meshes with two auxiliary gears on both sides to drive the lower rotating shaft and rotating rod to rotate. The rotating shaft and rotating rod drive a stirring shaft, a stirring rod, and a scraper to rotate, simultaneously stirring the material and scraping off the material from the inner wall surface of the reaction vessel. A pressure pump delivers cleaning liquid from a cleaning liquid tank to the rotating shaft and stirring shaft via a delivery pipe. The cleaning liquid is sprayed into the reaction vessel through nozzles for cleaning. However, this device is not only inconvenient for controlling the speed of raw material addition, but also cannot ensure the raw materials are added in a dispersed manner, easily causing uneven material distribution and resulting in uneven reaction. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model proposes a reaction device with controllable feeding, which solves the problem that existing rubber accelerator reaction vessels are not only inconvenient to control the feeding speed, but also cannot disperse the raw materials, easily causing uneven feeding.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A controllable feeding reaction device includes a reaction vessel and a stirring mechanism mounted on the reaction vessel. The reaction vessel has a solid feed inlet and a rotating material distribution mechanism located below the feed inlet. The rotating material distribution mechanism is rotatably connected to the reaction vessel, and the stirring mechanism cooperates with the rotating material distribution mechanism to drive its rotation. A feeding mechanism is connected to the solid feed inlet. This invention distributes the incoming solid raw materials through a rotating material distribution mechanism located directly below the solid feed inlet, allowing the material to disperse into the vessel body for rapid and uniform mixing, thereby avoiding uneven reaction.

[0006] Furthermore, the rotating material distribution mechanism includes a rotating cylinder rotatably connected to the reactor and several rotating blades disposed at the lower part of the rotating cylinder.

[0007] Furthermore, several rotating blades extend from the center of the rotating cylinder toward the outside of the rotating cylinder and are inclined downwards.

[0008] Furthermore, the lower ends of several rotating blades are connected to the rotating cylinder, and the upper ends are connected to a cone.

[0009] Furthermore, the connection points between several rotating blades and the cone intersect with the generatrix of the cone.

[0010] Furthermore, several rotating blades are arranged symmetrically between the cone and the rotating cylinder.

[0011] Furthermore, a connecting cylinder coaxial with the solid feed inlet is provided below the top of the reactor, and the rotating cylinder is rotatably connected to the connecting cylinder through a turntable bearing.

[0012] Furthermore, the stirring mechanism includes a stirring motor located at the top of the reactor and a stirring shaft connected to the output end of the stirring motor and vertically arranged inside the reactor. The stirring shaft is equipped with a driving gear, and the rotating cylinder is equipped with a driven gear that meshes with the driving gear.

[0013] Furthermore, the feeding mechanism includes a receiving hopper connected to the solid feed inlet, a screw conveying mechanism connected to the receiving hopper, and a weighing hopper disposed above the feed hopper of the screw conveying mechanism.

[0014] Furthermore, the weighing hopper is connected to the feed hopper of the screw conveyor mechanism via a flexible dust cover.

[0015] Furthermore, the motor of the screw conveyor is connected to a dual-output shaft gearbox. One output shaft of the dual-output shaft gearbox is connected to the rotating shaft of the screw conveyor, and the other output shaft is connected to a stirring rod. The stirring rod is inserted into the feed hopper of the screw conveyor and is equipped with a stirring support rod.

[0016] The beneficial effects of this utility model are: 1. This utility model uses a rotating material distribution mechanism located directly below the solid feed inlet to distribute the incoming solid raw materials, allowing the materials to disperse into the reactor body for rapid and uniform mixing, thereby avoiding uneven reaction. 2. This utility model uses a stirring mechanism and a rotating fabric-making mechanism for transmission connection. The rotation of the stirring mechanism drives the rotation of the rotating fabric-making mechanism, which is convenient and energy-saving. 3. This utility model controls the feeding speed through a screw conveyor mechanism, further avoiding uneven material distribution; 4. This utility model ensures quantitative feeding of solid materials by setting up a weighing hopper; 5. This utility model provides a flexible dust cover between the weighing hopper and the feed hopper of the screw conveyor mechanism, which serves to prevent dust without affecting the weighing function of the weighing hopper. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0019] 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, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown in Embodiment 1 of this utility model, a controllable feeding reaction device includes a reaction vessel 1 and a stirring mechanism mounted on the reaction vessel 1. A solid feed inlet is located at the top of the reaction vessel 1, and a rotating feeding mechanism is located below the top of the reaction vessel 1. The rotating feeding mechanism is positioned directly below the solid feed inlet and works in conjunction with it to distribute the incoming solid raw materials, facilitating rapid and uniform mixing and preventing uneven reaction. The rotating feeding mechanism is rotatably connected to the reaction vessel 1, and the stirring mechanism works in conjunction with the rotating feeding mechanism, i.e., the stirring mechanism and the rotating feeding mechanism are drively connected to drive the rotation of the rotating feeding mechanism. The rotation of the stirring mechanism drives the rotation of the rotating feeding mechanism, which is convenient and energy-saving. A feeding mechanism is connected to the solid feed inlet for easy feeding control.

[0021] Example 2 differs from Example 1 in that the rotating fabric feeding mechanism includes a rotating cylinder 2 rotatably connected to the reactor 1 and several rotating blades 3 disposed at the lower part of the rotating cylinder 2.

[0022] Furthermore, such as Figure 1As shown, a connecting cylinder coaxial with the solid feed inlet is provided below the top of the reactor 1. The rotating cylinder 2 is rotatably connected to the connecting cylinder through a turntable bearing 6. Several rotating blades 3 are arranged symmetrically at the lower end of the rotating cylinder 2, and all the rotating blades 3 extend from the center of the rotating cylinder 2 toward the outside of the rotating cylinder 2 and are inclined downward.

[0023] Furthermore, such as Figure 1 As shown, the lower ends of several rotating blades 3 are connected to the rotating cylinder 2, and the upper ends are connected to cones 4. By setting cones 4 on the axis of the rotating cylinder 2, it is not only convenient to connect and fix the rotating cylinder 2, but the cones 4 themselves can also play a role in dispersing materials.

[0024] Example 3 differs from Example 2 in that, as Figure 1 As shown, the connection points of several rotating blades 3 with the cone 4 intersect the generatrix of the cone 4. In this embodiment, the rotating blades 3 are flat plates, and the length and width directions of the rotating blades 3 intersect the axial and radial directions of the rotating cylinder 2. That is, the rotating blades 3 are inclined not only in the length direction of the rotating cylinder but also in the radial direction of the rotating cylinder, thus forming a spiral pattern, which facilitates better material dispersion. In another embodiment, the rotating blades 3 are curved blades, which facilitates the dispersion of materials during rotation.

[0025] Example 4 differs from Example 3 in that, as Figure 1 As shown, the stirring mechanism includes a stirring motor fixed to the top of the reactor 1 and a stirring shaft connected to the output end of the stirring motor and vertically installed inside the reactor. The stirring shaft is equipped with a drive gear 5, and the rotating cylinder 2 is equipped with a driven gear that meshes with the drive gear 5. Thus, the rotation of the stirring mechanism drives the rotation of the rotating cloth feeding mechanism, which is convenient and energy-saving.

[0026] Example 5 differs from Example 3 in that, as Figure 1 As shown, the feeding mechanism includes a receiving hopper 7 connected to the solid feed inlet, a screw conveyor mechanism 8 connected to the receiving hopper 7, and a weighing hopper 10 disposed above the feeding hopper of the screw conveyor mechanism 8. The discharge end of the screw conveyor mechanism 8 is fixed inside the receiving hopper 7. The feeding hopper of the screw conveyor mechanism 8 receives the discharge from the weighing hopper 10. The weighing hopper 10 adopts a structure found in the prior art, with a switch valve at its bottom outlet, which is located directly above the feeding hopper of the screw conveyor mechanism 8. The feeding rate can be controlled by the screw conveyor mechanism 8. Furthermore, the reaction device also includes a support frame for supporting the screw conveyor mechanism 8 and the weighing hopper 10.

[0027] Example 6 differs from Example 5 in that, as Figure 1As shown, to prevent solid material from entering the feed hopper of the screw conveyor mechanism 8 and causing blockage after the bottom outlet of the weighing hopper 10 opens, a dual-output shaft gearbox can be connected to the motor of the screw conveyor mechanism 8. One output shaft of the dual-output shaft gearbox is connected to the rotating shaft of the screw conveyor mechanism, and the other output shaft is connected to a stirring rod. The stirring rod passes into the feed hopper of the screw conveyor mechanism and is equipped with a stirring support rod 81. This stirs the material in the feed hopper during the conveying process, preventing material from accumulating and affecting the discharge after the bottom outlet of the weighing hopper 10 opens. Furthermore, the stirring rod is rotatably connected to the feed hopper via bearings.

[0028] Example 7 differs from Example 5 in that, as Figure 1 As shown, the weighing hopper 10 is connected to the feed hopper of the screw conveyor mechanism 8 via a flexible dust cover 9. The flexible dust cover 9 serves to prevent dust accumulation. The flexible dust cover 9 is lightweight and not rigidly connected to the weighing hopper 10, so its influence on the weighing hopper is negligible. It can also be used for weighing verification of the weighing hopper 10 after the flexible dust cover 9 is installed. Furthermore, the flexible dust cover 9 should be cleaned regularly to avoid affecting the weighing accuracy of the weighing hopper 10.

[0029] Example 8 differs from Example 7 in that, as Figure 1 As shown, depending on the type of solid raw material, multiple solid feed ports, rotating material distribution mechanisms, and feeding mechanisms can be set on the reactor to facilitate the feeding control of each solid raw material.

[0030] Example 9 differs from Example 1 in that, as Figure 1 As shown, the bottom of the reactor 1 is also provided with a detection port 11, which is used to connect a solid residue analyzer in the prior art to facilitate the determination of the reaction process.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features therein, within the spirit and principles of the present utility model, shall not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model, and shall all be included within the protection scope of the present utility model.
