Description
Technical Field
[0001] This utility model relates to the technical field of chemical production equipment, and in particular to a safe feeding device for chemical production. Background Technology
[0002] In chemical production, the feeding process is a crucial step in ensuring reaction efficiency and product quality. With increasingly stringent safety and environmental protection requirements in the chemical industry, traditional feeding devices have revealed numerous shortcomings in areas such as airtightness, raw material pretreatment, and operational safety. For example, powdery or granular raw materials can easily generate dust during feeding, polluting the production environment and potentially posing occupational health risks to operators. Furthermore, the presence of agglomerates or uneven particle sizes in the raw materials can lead to incomplete reactions or equipment blockages, affecting production continuity.
[0003] In existing technologies, traditional feeding devices mostly use a single fixed blade or a simple stirring paddle to crush agglomerated raw materials. However, due to limitations in the number, arrangement, and rotation speed of the blades, it is difficult to fully crush hard or large-sized agglomerated materials. Furthermore, the fine particles after crushing are prone to re-agglomeration, forming secondary agglomerates, resulting in poor processing efficiency. Although some devices are equipped with independent crushing mechanisms, the crushed raw materials need to be conveyed into the mixing zone through an additional conveying device, which complicates the process. Moreover, the raw materials are prone to segregation or accumulation during the transfer process, further aggravating the problem of uneven mixing, resulting in poor practicality. Therefore, this utility model discloses a safe feeding device for chemical production to solve the problems of insufficient crushing of agglomerated raw materials and uneven mixing caused by the separation of the crushing and mixing processes in traditional feeding devices. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a safe feeding device for chemical production, so as to solve the problems of insufficient crushing of agglomerated raw materials and uneven mixing caused by the separation of crushing and stirring processes in traditional feeding devices.
[0005] To achieve the above objectives, this utility model provides a safe feeding device for chemical production, comprising: a feeding tank, a conical funnel installed at the bottom of the feeding tank, the conical funnel being installed upside down, a discharge pipe installed in the middle of the conical funnel, and multiple sets of support columns arranged in an array around the bottom of the conical funnel; an upper cover installed at the top of the feeding tank, a feed pipe installed on one side of the upper end face of the upper cover; a stirring assembly provided inside the feeding tank, the stirring assembly being used to fully mix and stir the raw materials added to the feeding tank; and a crushing assembly provided at the lower part of the feeding tank, the crushing assembly being used to crush the agglomerated raw materials added to the feeding tank.
[0006] Preferably, the stirring assembly includes a servo motor, the output shaft of which is engaged and rotatably mounted in the middle of the upper cover, and a stirring shaft is mounted on the output end of the servo motor. Multiple stirring rods are arranged in a vertical array on the side wall of the stirring shaft, and a connecting post is provided between the side wall of the output end of the servo motor and the upper cover.
[0007] Preferably, the upper cover has a first circular hole with the same diameter as the output shaft at the center corresponding to the position of the servo motor output shaft, and the upper cover has a second circular hole with the same diameter as the feed pipe at the position of the feed pipe.
[0008] Preferably, the crushing assembly includes a primary rotating ring, the upper end face of which is fixedly mounted at the middle of the other end of the stirring shaft. A secondary rotating ring is rotatably mounted on the outer wall of the primary rotating ring. A loading ring is rotatably mounted on the outer side of the secondary rotating ring, and the outer wall of the loading ring is fixedly mounted on the inner wall of the feeding tank. Multiple sets of material passages are uniformly arranged in a circular array on the loading ring. Multiple sets of first crushing blades are uniformly arranged in a circular array on the upper end face of the primary rotating ring. Multiple sets of second crushing blades are uniformly arranged in a circular array on the upper end face of the secondary rotating ring. A drive gear is mounted on the lower end face of the primary rotating ring. A mounting post is mounted on the lower end face of the secondary rotating ring. A connecting gear is rotatably mounted on the mounting post. A driven ring is mounted on the lower end face of the secondary rotating ring. A gear groove is mounted on the inner side wall of the driven ring. The driven ring meshes with the connecting gear, and the connecting gear meshes with the gear groove.
[0009] Preferably, the outer wall of the first-stage rotating ring and the inner wall of the second-stage rotating ring are engaged and rotatably mounted, and the inner diameter of the first-stage rotating ring is the same as the outer diameter of the first-stage rotating ring.
[0010] Preferably, the outer wall of the secondary rotating ring is engaged and rotatably mounted with the inner wall of the loading ring, and the inner diameter of the loading ring is the same as the outer diameter of the secondary rotating ring.
[0011] Preferably, multiple sets of the first crushing blades are installed obliquely on the upper surface of the first-stage rotating ring, and multiple sets of the second crushing blades are installed obliquely on the upper surface of the second-stage rotating ring, with the orientation of the multiple sets of the first crushing blades opposite to that of the multiple sets of the second crushing blades.
[0012] Preferably, a third circular hole with the same diameter as the mounting post is provided in the middle of the connecting gear corresponding to the position of the mounting post.
[0013] The beneficial effects of this utility model are: This invention achieves coordinated crushing and mixing of agglomerated raw materials through an integrated structure of a two-stage differential speed rotary crushing component and a mixing component, significantly improving the processing efficiency and uniformity of the feed. The primary and secondary rotating rings rotate in opposite directions via gear transmission, driving the first and second crushing blades to shear, tear, and refine the agglomerated raw materials at different directions and speeds. The obliquely arranged blade design not only increases the crushing area but also generates shearing force through the relative motion between the blades, effectively crushing hard or large agglomerated materials and avoiding the problem of insufficient crushing by traditional single blades. Simultaneously, the crushed raw material falls directly into the mixing zone, where it is continuously agitated by the mixing shaft and rod, preventing fine particles from re-agglomerating and forming secondary agglomerates, ensuring a uniform particle size distribution. Furthermore, the multiple feed inlets on the loading ring further optimize the raw material flow path, preventing material accumulation in the crushing zone and improving the continuity of crushing and mixing. Through the above-mentioned collaborative design, this utility model solves the problem of uneven mixing caused by the separation of crushing and stirring processes in traditional feeding devices, providing uniform and lumpy raw materials for subsequent reactions, and significantly improving reaction efficiency and product quality.
[0014] This invention effectively addresses the shortcomings of traditional feeding devices in dust control and operational safety through a fully enclosed, sealed structure and modular design. The feeding tank, top cover, conical funnel, and other components employ a multi-layered sealing structure, combined with a negative pressure suction system, to collect dust generated during the crushing process in real time, preventing leakage into the production environment and ensuring operator health and environmental compliance. Simultaneously, the integrated design of the crushing and mixing components reduces intermediate conveying links, avoiding segregation and accumulation of raw materials during transfer, further reducing the risk of dust generation. Regarding operational safety, this invention completely encloses the crushing blades within the feeding tank and incorporates protective structures to prevent operators from accidentally touching rotating parts, significantly reducing the risk of mechanical injury. Furthermore, the modular design (such as quick-release blades and split crushing components) makes equipment maintenance more convenient; blade replacement and equipment cleaning do not require disassembling the entire structure, greatly shortening downtime and reducing maintenance costs. Through these improvements, this invention significantly enhances production safety and equipment practicality while ensuring efficient feeding, providing chemical enterprises with a solution that combines environmental protection, safety, and economic benefits.

[0020] This utility model provides, for example Figures 1 to 4The invention discloses a chemical production safety feeding device, comprising: a feeding tank 1, a conical funnel 2 installed at the bottom of the feeding tank 1, the conical funnel 2 being installed upside down, a discharge pipe 3 installed in the middle of the conical funnel 2, and multiple sets of support columns 4 arranged in an array around the bottom of the conical funnel 2; an upper cover 5 installed at the top of the feeding tank 1, a feed pipe 6 installed on one side of the upper end face of the upper cover 5; a stirring assembly inside the feeding tank 1 for fully mixing and stirring the raw materials added to the feeding tank 1; and a crushing assembly at the lower part of the feeding tank 1 for crushing the agglomerated raw materials added to the feeding tank 1. This invention achieves the coordinated operation of crushing and mixing agglomerated raw materials through the integrated structure of the dual-stage differential speed rotating crushing assembly and the stirring assembly, significantly improving the processing efficiency and uniformity of the feeding process. The primary rotating ring 13 and the secondary rotating ring 12 rotate in opposite directions at different speeds via gear transmission, driving the first crushing blade 14 and the second crushing blade 15 to shear, tear, and refine the agglomerated raw material at different directions and speeds. The obliquely arranged blade design not only increases the crushing area but also generates shearing force through the relative motion between the blades, effectively crushing hard or large-sized agglomerates and avoiding the problem of insufficient crushing by traditional single blades. Simultaneously, the crushed raw material falls directly into the mixing zone, where it is continuously agitated by the mixing shaft 8 and the mixing rod 9 to prevent fine particles from re-agglomerating and forming secondary agglomerates, ensuring a uniform particle size distribution. Furthermore, the multiple sets of feed inlets 11 on the loading ring 10 further optimize the raw material flow path, preventing material accumulation in the crushing zone and improving the continuity of crushing and mixing. Through the above synergistic design, this invention solves the problem of uneven mixing caused by the separation of crushing and mixing processes in traditional feeding devices, providing uniform, agglomerated raw materials for subsequent reactions and significantly improving reaction efficiency and product quality. This invention effectively addresses the shortcomings of traditional feeding devices in dust control and operational safety through a fully enclosed, sealed structure and modular design. The feeding tank 1, along with components such as the upper cover 5 and the conical funnel 2, employs a multi-layered sealing structure, combined with a negative pressure suction system to collect dust generated during the crushing process in real time, preventing leakage into the production environment and ensuring operator health and environmental compliance. Simultaneously, the integrated design of the crushing and mixing components reduces intermediate conveying links, avoiding segregation and accumulation of raw materials during transfer, further reducing the risk of dust generation. Regarding operational safety, this invention completely encloses the crushing blades within the feeding tank 1 and incorporates protective structures to prevent operators from accidentally touching rotating parts, significantly reducing the risk of mechanical injury. Furthermore, the modular design (such as quick-release blades and split crushing components) makes equipment maintenance more convenient; blade replacement and equipment cleaning do not require disassembling the entire structure, greatly shortening downtime and reducing maintenance costs. Through these improvements, this invention significantly enhances production safety and equipment practicality while ensuring efficient feeding, providing chemical enterprises with a solution that combines environmental protection, safety, and economic benefits.
[0021] Furthermore, in this example, such as Figure 2 As shown, the stirring assembly includes a servo motor 7. The output shaft of the servo motor 7 is rotatably mounted in the middle of the upper cover 5, and a stirring shaft 8 is mounted on the output end of the servo motor 7. Multiple stirring rods 9 are vertically arrayed on the side wall of the stirring shaft 8. A connecting post is provided between the side wall of the output end of the servo motor 7 and the upper cover 5. A first circular hole with the same diameter as the output shaft is opened in the middle of the upper cover 5 corresponding to the position of the servo motor 7's output shaft, and a second circular hole with the same diameter as the feed pipe 6 is opened on the upper cover 5 corresponding to the position of the feed pipe 6. The core of the stirring assembly consists of the servo motor 7, the stirring shaft 8, and the multiple stirring rods 9. The servo motor 7 is rotatably mounted by engaging the output shaft with the first circular hole in the middle of the upper cover 5, ensuring stable motor operation. The connecting post provides axial limiting between the output shaft and the upper cover 5, preventing axial displacement due to motor vibration. When the servo motor 7 starts, the output shaft drives the stirring shaft 8 to rotate at a preset speed, and the multiple stirring rods 9 vertically arrayed on the side wall of the stirring shaft 8 rotate synchronously. The rotation of the stirring rod 9 creates a three-dimensional mixing flow field within the feeding tank 1, thoroughly mixing and agitating the added raw materials. Specifically, the rotation of the stirring rod 9 not only propels the raw materials to circulate horizontally but also applies shear force to the raw materials through its blade structure, promoting the uniform dispersion of raw material particles of different sizes or densities. Furthermore, the feed pipe 6 connects to the feeding tank 1 through the second circular hole of the upper cover 5, ensuring that the raw materials can smoothly enter the tank and rapidly integrate into the mixing system under the action of the stirring rod 9, avoiding local accumulation or segregation. Through the above design, the stirring assembly achieves efficient and uniform mixing of the raw materials, providing a stable material basis for subsequent reactions.
[0022] Furthermore, in this example, such as Figure 2 , Figure 3 and Figure 4As shown, the crushing assembly includes a primary rotating ring 13. The upper end face of the primary rotating ring 13 is fixedly mounted at the other end of the stirring shaft 8. A secondary rotating ring 12 is rotatably mounted on the outer wall of the primary rotating ring 13. A loading ring 10 is rotatably mounted on the outer side of the secondary rotating ring 12. The outer wall of the loading ring 10 is fixedly mounted on the inner wall of the feeding tank 1. Multiple sets of material passages 11 are uniformly arranged in a circular array on the loading ring 10. Multiple sets of first crushing blades 14 are uniformly arranged in a circular array on the upper end face of the primary rotating ring 13. The unit is equipped with multiple sets of second crushing blades 15. A drive gear 18 is mounted on the lower end face of the primary rotating ring 13. A mounting column 20 is mounted on the lower end face of the secondary rotating ring 12. A connecting gear 19 is rotatably mounted on the mounting column 20. A driven ring 16 is mounted on the lower end face of the secondary rotating ring 12. A gear groove 17 is mounted on the inner side wall of the driven ring 16. The driven ring 16 meshes with the connecting gear 19, and the connecting gear 19 meshes with the gear groove 17. The crushing assembly achieves efficient crushing and uniform dispersion of agglomerated raw materials through the synergistic effect of the two-stage differential rotation structure and the gear transmission system. The primary rotating ring 13 is fixed to the end of the stirring shaft 8 and rotates synchronously with it. Its outer wall is rotatably connected to the secondary rotating ring 12 through a snap-fit structure. The outer wall of the secondary rotating ring 12 is then rotatably engaged with the loading ring 10 fixed to the inner wall of the feeding tank 1, forming two independent rotating units. During power transmission, the drive gear 18 on the lower end face of the primary rotating ring 13 drives the connecting gear 19 to rotate along the mounting column 20. The connecting gear 19 simultaneously meshes with the gear groove 17 of the driven ring 16 on the lower end face of the secondary rotating ring 12, causing the secondary rotating ring 12 and the primary rotating ring 13 to rotate in opposite directions at a differential speed. Multiple sets of first crushing blades 14 on the upper end face of the rotating ring 13 and multiple sets of second crushing blades 15 on the upper end face of the secondary rotating ring 12 are arranged obliquely in opposite directions. During the reverse differential rotation, the shearing and tearing action between the blades refines the agglomerated raw materials. The crushed particles fall directly into the mixing zone through the uniformly distributed feed ports 11 on the loading ring 10. The disturbance effect of the mixing shaft 8 and the mixing rod 9 works together to prevent secondary agglomeration and ensure the uniformity of the raw materials. At the same time, the locking rotating installation structure ensures rotational stability. The gear transmission system optimizes crushing efficiency and energy consumption, and the whole process achieves continuous and efficient synergy between crushing and mixing.
[0023] Furthermore, in this example, such as Figure 3 Siberian Husky Figure 4As shown, the outer wall of the first-stage rotating ring 13 is engaged and rotatably mounted with the inner wall of the second-stage rotating ring 12, and the inner diameter of the first-stage rotating ring 13 is the same as its outer diameter. The outer wall of the second-stage rotating ring 12 is engaged and rotatably mounted with the inner wall of the loading ring 10, and the inner diameter of the loading ring 10 is the same as its outer diameter. Multiple sets of first crushing blades 14 are obliquely arranged on the upper end face of the first-stage rotating ring 13, and multiple sets of second crushing blades 15 are obliquely arranged on the upper end face of the second-stage rotating ring 12, with the orientation of the multiple sets of first crushing blades 14 opposite to that of the multiple sets of second crushing blades 15. The second crushing blade 15 faces the opposite direction. A third circular hole, with the same diameter as the mounting post 20, is provided in the middle of the connecting gear 19 corresponding to the position of the mounting post 20. The outer wall of the first-stage rotating ring 13 and the inner wall of the second-stage rotating ring 12 are tightly fitted and rotated together via a snap-fit structure slide rail. The outer diameter of the first-stage rotating ring 13 and the inner diameter of the second-stage rotating ring 12 are precisely matched to ensure rotational concentricity. Similarly, the outer wall of the second-stage rotating ring 12 and the inner wall of the loading ring 10 are connected by a snap-fit rotation, and the inner diameter of the loading ring 10 is perfectly matched to the outer diameter of the second-stage rotating ring 12, forming a stable double-stage nested rotation. This system, with its size-matching design, ensures the coaxiality of the rotating components while reducing frictional resistance and vibration through a locking structure. Multiple sets of first-stage crushing blades 14, arranged obliquely on the upper surface of the first-stage rotating ring 13, and multiple sets of second-stage crushing blades 15, arranged obliquely on the upper surface of the second-stage rotating ring 12, are installed in opposite directions. When the first-stage rotating ring 13 rotates with the stirring shaft 8, the second-stage rotating ring 12 achieves reverse differential rotation through a gear transmission system. The two sets of blades form a shearing overlap area during their reverse motion. The obliquely arranged blades enhance the tearing and refining effect on agglomerated raw materials by increasing the contact area and the relative speed difference. The reverse blade layout prevents raw materials from escaping in a single direction, ensuring sufficient crushing. The third circular hole in the middle of the connecting gear 19 has the same diameter as the mounting post 20 on the lower end face of the secondary rotating ring 12. Stable rotational installation is achieved through clearance fit. This design not only ensures the flexible rotation of the connecting gear 19 but also prevents its deviation through axial limiting, ensuring that the gear transmission system accurately transmits power. This makes the differential rotation of the primary rotating ring 13 and the secondary rotating ring 12 stable and controllable. Finally, through structural size adaptation, blade layout optimization, and improved gear installation accuracy, efficient collaborative operation and low-energy stable operation of the crushing components are achieved.
