Detailed Description of the Embodiments

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are merely part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Referring to Figures 1-4 , the present utility model provides a technical solution: a reactor feeding assembly, comprising a feeding pipe 2 and a feeding barrel 3, wherein the feeding pipe 2 is arranged at the bottom end of the feeding barrel 3; The top end of the inner side of the feeding barrel 3 is rotatably connected with a rotating cylinder 8 through a bearing, the bottom end of the rotating cylinder 8 is fixedly connected with lower tooth members 801 distributed at equal angles, one side of the top end of the feeding barrel 3 is fixedly connected with a mounting frame 6, the inner side of the mounting frame 6 is connected with a rotating shaft 9 penetrating through the rotating cylinder 8 through a bearing, the bottom end of the rotating shaft 9 is fixedly connected with an upper tooth member 901, and the lower tooth members 801 cooperate with the upper tooth member 901 to perform shearing and impact type pre-crushing on caked raw materials, so as to solve the problem of blockage of the feeding pipe 2.

[0017] Specifically, the caked raw materials entering the feeding barrel 3 are subjected to shearing and impact type pre-crushing through the lower tooth members 801 and the upper tooth member 901, so that large pieces of raw materials are crushed to a qualified particle size, so as to prevent the caked raw materials from blocking the feeding pipe 2 and improve the subsequent mixing efficiency.

[0018] In Figures 2-4 : each lower tooth member 801 comprises a first diamond-shaped cross bar fixedly connected with the rotating cylinder 8 and a lower tooth frame fixedly connected to the bottom end of the first diamond-shaped cross bar, the lower tooth frame is configured in a "shi"-shaped structure, the upper tooth member 901 comprises a second diamond-shaped cross bar fixedly connected with the rotating shaft 9 and an upper tooth frame fixedly connected to the bottom end of the second diamond-shaped cross bar, the upper tooth frame is configured in a "gan"-shaped structure, the upper tooth frame and the lower tooth frame are arranged in a staggered manner, and both the upper tooth frame and the lower tooth frame are formed by combining a plurality of mutually perpendicular diamond-shaped rods.

[0019] Specifically, the diamond-shaped edges can form "shearing blades", which can increase the shearing and impact force when contacting with the materials. Cooperating with the staggered upper tooth frame and lower tooth frame, the caked raw materials can be crushed more easily, and the probability of raw materials adhering to the surface of the rods is reduced. Moreover, the side edges of the diamond shape are inclined, which can guide the flow of raw materials between the upper tooth frame and the lower tooth frame, avoid the accumulation of raw materials at the upper tooth frame and the lower tooth frame, and ensure the smoothness of the crushing process.

[0020] Specifically, the multi-rod combined structure of the "shi" and "gan" shapes can form multi-point contact with the raw materials during rotation, cooperate with the movement track of reverse rotation to cover more raw material areas, and improve the uniformity of pre-crushing.

[0021] exist Figures 2-4 In the middle: The bottom end of the upper toothed part 901 is fixedly connected with a protrusion 10. The protrusion 10 is used to prevent the raw material from clogging the mesh of the screen plate 7, so as to improve the screening efficiency.

[0022] Specifically, when the upper toothed part 901 rotates, the convex strip 10 rotates synchronously so as to move the raw material through the convex strip 10, prevent the screen plate 7 from clogging, and thus improve the screening effect and efficiency.

[0023] exist Figure 2 and Figure 4 In the middle: A screen plate 7 is installed at the bottom of the inner side of the feed hopper 3. The screen plate 7 is used to ensure the uniformity of feeding.

[0024] Specifically, the pre-crushed raw materials are screened through the sieve plate 7, allowing only materials that meet the particle size requirements to pass through, thus ensuring uniform feeding.

[0025] exist Figures 1-4 In the middle: The top of the feed hopper 3 is provided with a drive mechanism 4. The drive mechanism 4 is used to drive the rotating cylinder 8 to rotate in the opposite direction to the rotating shaft 9. The drive mechanism 4 includes a support shaft 405 connected to the feed hopper 3 through a bearing and a driven gear 404 sleeved on the surface of the rotating cylinder 8. The surface of the support shaft 405 is sleeved with a drive gear 403 that meshes with the driven gear 404. The drive gear 403 and the driven gear 404 cooperate to make the rotating cylinder 8 rotate in the opposite direction to the support shaft 405.

[0026] Specifically, when the servo motor 401 is working, the output end of the servo motor 401 drives the support shaft 405 and the drive gear 403 to rotate. Since the driven gear 404 is meshed with the drive gear 403, the driven gear 404 and the rotating cylinder 8 rotate in the opposite direction to the rotation of the support shaft 405. The rotation of the rotating cylinder 8 drives the lower gear 801 to rotate synchronously.

[0027] exist Figures 2-4 In the middle: A pulley set 402 is provided between the support shaft 405 and the rotating shaft 9. The pulley set 402 is used to make the rotating shaft 9 rotate in the same direction as the support shaft 405. A servo motor 401 connected to the support shaft 405 via a coupling is installed on the other side of the top of the feed barrel 3. The servo motor 401 is used to drive the support shaft 405 to rotate.

[0028] Specifically, since the rotating shaft 9 and the support shaft 405 are linked by the pulley group 402, the rotating shaft 9 rotates in the same direction as the support shaft 405, and the rotation of the rotating shaft 9 drives the upper gear 901 to rotate synchronously.

[0029] Specifically, the lower toothed part 801 and the upper toothed part 901 shear and impact pre-crush the agglomerated raw material entering the feed barrel 3, breaking the large pieces of raw material into qualified particle size, so as to prevent the agglomerated raw material from clogging the feed pipe 2 and improve the subsequent mixing efficiency. This method can solve the problem of clogging of the feed pipe 2, eliminate the need for manual shutdown for cleaning, ensure production continuity, reduce labor costs, and eliminate safety hazards during the cleaning process.

[0030] Please see Figure 1 , Figure 2 and Figure 4 A reaction vessel includes a vessel body 1, with a mounting frame 5 fixedly connected to one side of the top of the vessel body 1. The mounting frame 5 is used to stably support a feed tank 3, which is installed inside the mounting frame 5. A stirring assembly 101 is provided inside the vessel body 1, and the end of the feed pipe 2 away from the feed tank 3 is connected to the vessel body 1.

[0031] Specifically, the vessel body 1 is used to contain raw materials and provide a closed space for the reaction, and can withstand the temperature, pressure and other conditions required for the reaction. The feed pipe 2 is a channel connecting the feed tank 3 and the vessel body 1, used to transport the screened and crushed raw materials into the vessel body 1.

[0032] The servo motor 401 is started, and the output end of the servo motor 401 drives the support shaft 405 to rotate. At the same time, the support shaft 405 drives the drive gear 403 to rotate synchronously. Through the meshing of the driven gear 404 and the drive gear 403, the driven gear 404 drives the rotating cylinder 8 to rotate in the opposite direction to the support shaft 405. At the same time, the support shaft 405 is linked to the rotating shaft 9 through the pulley group 402, so that the rotating shaft 9 rotates in the same direction as the support shaft 405. When the rotating cylinder 8 rotates, it drives the lower gear 801 to rotate. When the rotating shaft 9 rotates, it drives the upper gear 901 to rotate. The upper and lower gears are staggered to shear and impact the agglomerated raw material entering the feed barrel 3 to pre-crush it, breaking the large raw material into qualified particle size. The synchronously moving convex strip 10 continuously contacts and moves the surface of the screen plate 7 to prevent the screen plate 7 from clogging. The crushed qualified raw material falls into the feed pipe 2 through the screen plate 7 so that it can be sent into the kettle body 1 through the feed pipe 2. The raw material entering the kettle body 1 is stirred and mixed by the stirring component 101. Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source or a battery and controlled by a control box, control panel, or controller. Any content not described in detail in this document is prior art known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
