Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a granulator with an anti-stacking structure for organic fertilizer production. Background Technology

[0002] A granulator is a device used to mechanically transform powdery or loose materials into granules of a specific shape and size. It is widely used in industries such as chemical, pharmaceutical, feed, building materials, and metallurgy. The main function of this equipment is to improve the flowability of materials, facilitate storage and transportation, and enhance the uniformity and stability of the product. The granulation process typically includes mixing, pressurizing, extrusion, and drying. Common types include rotary drum granulators, extrusion granulators, and fluidized bed granulators.

[0003] Currently, existing organic fertilizer granulators suffer from a lack of effective anti-accumulation design in their feeding equipment, leading to significant accumulation of organic fertilizer raw material briquettes at the top inlet of the roller press granulator. These accumulated briquettes not only clog the inlet and extrusion cavity, forcing frequent shutdowns for cleaning, but also exert additional downward pressure on the rotating granulation extrusion rollers. This exacerbates friction and wear between the two sets of rollers and may alter the extrusion gap, weakening the granulation effect and ultimately impacting pellet quality and production stability. Therefore, these limitations exist in their application.

[0004] Based on this, we propose a granulator with an anti-stacking structure for organic fertilizer production to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a granulator with an anti-stacking structure for organic fertilizer production, which can solve the problem that the lack of anti-stacking design in the feeding equipment of existing organic fertilizer granulators leads to the accumulation and blockage of raw material rods in the feed inlet and extrusion chamber during the conveying process, and applies additional downward pressure to the extrusion rollers and changes the extrusion gap, thereby affecting the granulation quality and production stability.

[0007] To solve the above-mentioned technical problems, this utility model provides a granulator with an anti-stacking structure for organic fertilizer production, adopting the following technical solution: it includes a roller press granulator, an anti-stacking feeder is installed on one side of the roller press granulator, raw material rods are arranged at equal intervals on the top of the anti-stacking feeder, the anti-stacking feeder includes a material conveying frame, a material rod conveyor belt is installed on the top of the material conveying frame, a material rod transfer component is installed at one end of the material conveying frame, and a material rod unloading component is also provided at the end of the material rod transfer component away from the material conveying frame.

[0008] Optionally, the material bar feeding assembly includes a support base, one end of which is equipped with a discharge hopper, and a chain conveyor is provided on the side of the support base near the discharge hopper.

[0009] Optionally, the material bar transfer assembly includes a material bar transfer box, and both the top of the material bar transfer box and the top of the unloading hopper are equipped with baffles.

[0010] Optionally, the inside of the bar transfer box is connected to a transfer roller via a bearing, a first guide plate is inclinedly connected to the side of the bar transfer box near the transfer roller, and a second guide plate is also inclinedly provided at the bottom of the bar transfer box.

[0011] Optionally, the material bar transfer box has a discharge port on the side near the second guide plate. The discharge port is located directly above the input end of the chain conveyor. A drive motor is also installed on the outer side of the material bar transfer box, and the output end of the drive motor is in transmission cooperation with the transfer roller.

[0012] Optionally, the top of the roller press granulator is provided with a feed inlet, and two sets of granulator rollers are connected inside the feed inlet via bearings. A motor drive box is installed on the outside of the roller press granulator, and the motor drive box is connected to the two sets of granulator rollers for transmission. A discharge plate is also provided at the bottom of one end of the roller press granulator.

[0013] In summary, this utility model has at least one of the following beneficial effects:

[0014] 1. The organic fertilizer granulator designed in this scheme achieves efficient and stable feeding of organic fertilizer raw material rods through the close cooperation of the rod conveyor belt, rod transfer component, and rod discharge component. This effectively avoids the accumulation and blockage problems that easily occur during the conveying process of raw material rods in traditional equipment. The rod conveyor belt ensures that the raw material rods are smoothly transported from the top of the anti-accumulation feeder to the rod transfer component. The transfer roller and guide plate inside the rod transfer component precisely guide the movement direction of the raw material rods, so that they are smoothly discharged from the discharge port and accurately fall into the rod discharge component. In this way, the entire feeding process is smooth and unobstructed, realizing a uniform and continuous supply of raw material rods, thereby improving the production efficiency and operational stability of the granulator.

[0015] 2. The organic fertilizer granulator designed in this solution optimizes the feeding system of the granulation equipment, providing a uniform and stable supply of raw materials to the roller press granulator. This results in high quality and high stability in the granulation process. The equidistant arrangement and stable transmission speed of the material bar conveyor belt, combined with the precise guidance and transfer function of the material bar transfer component and the uniform material distribution capability of the material bar unloading component, ensures that the raw material bars entering the roller press granulator are evenly distributed and the flow rate is stable. This uniform and stable raw material supply helps the granulator rollers maintain a stable extrusion gap and uniform extrusion pressure during the extrusion process, thereby producing organic fertilizer granules with regular shape, consistent size, and qualified strength, significantly improving product quality. At the same time, by avoiding equipment failures and frequent shutdowns for cleaning caused by raw material accumulation, the granulation process is made efficient and stable, extending the service life of the equipment and reducing production costs. This provides a more reliable and efficient granulation solution for the organic fertilizer production industry. Attached Figure Description

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.

[0024] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of an organic fertilizer production granulator with an anti-accumulation structure, comprising a roller press granulator 1, an anti-accumulation feeder 2 installed on one side of the roller press granulator 1, raw material rods 3 arranged equidistantly on the top of the anti-accumulation feeder 2, the anti-accumulation feeder 2 including a material conveyor frame 4, a material rod conveyor belt 5 installed on the top of the material conveyor frame 4, a material rod transfer component 6 installed at one end of the material conveyor frame 4, and a material rod unloading component 7 provided at the end of the material rod transfer component 6 away from the material conveyor frame 4. Through the close cooperation between the material rod conveyor belt 5, the material rod transfer component 6, and the material rod unloading component 7, this organic fertilizer granulator effectively prevents the raw material rods 3 from accumulating and clogging during the feeding and granulation stages, ensuring the continuity and stability of the granulation process. This smooth and anti-accumulation feeding method provides a uniform and stable supply of raw materials to the roller press granulator 1, enabling the granulator rollers 19 to extrude and granulate the raw material rods 3 under good working conditions.

[0025] The material bar unloading assembly 7 includes a support base 8, with a discharge hopper 9 installed at one end of the support base 8. A chain conveyor 10 is installed on the side of the support base 8 near the discharge hopper 9. The material bar unloading assembly 7 consists of the support base 8, the discharge hopper 9, and the chain conveyor 10, and can transfer and convey the raw material bars 3 conveyed on the material bar conveyor belt 5. The material bar transfer assembly 6 includes a material bar transfer box 11, and baffles 12 are installed on the top of both the material bar transfer box 11 and the discharge hopper 9. The baffles 12 installed on the top of the unloading hopper 9 can limit and block the two ends of the raw material rod 3 during the conveying process. The inside of the material rod transfer box 11 is connected to the transfer roller 13 through the bearing. The first guide plate 14 is inclinedly connected to the side of the material rod transfer box 11 near the transfer roller 13. The bottom of the material rod transfer box 11 is also inclinedly provided with a second guide plate 15. The first guide plate 14 and the second guide plate 15 provided inside the material rod transfer box 11 are used for the introduction and export of the raw material rod 3.

[0026] A discharge port 16 is provided on the side of the material bar transfer box 11 near the second guide plate 15. The discharge port 16 is located directly above the input end of the chain conveyor 10. A drive motor 17 is also installed on the outer side of the material bar transfer box 11. The output end of the drive motor 17 is connected to the transfer roller 13 for transmission. Through the discharge port 16 on the side of the material bar transfer box 11, which is located directly above the input end of the chain conveyor 10, the raw material bars 3 transferred inside the material bar transfer box 11 can directly roll onto the chain plate at the input end of the chain conveyor 10. A feed port 18 is provided on the top of the roller press granulator 1. The feed inlet 18 is connected to two sets of granulator rollers 19 via bearings. A motor drive box 20 is installed on the outside of the roller granulator 1. The motor drive box 20 is connected to the two sets of granulator rollers 19. A discharge plate 21 is also provided at the bottom of one end of the roller granulator 1. By installing the motor drive box 20 on the outside of the roller granulator 1 and connecting the motor drive box 20 to the two sets of granulator rollers 19, when the motor drive box 20 is powered on, it can drive the two sets of granulator rollers 19 to rotate inside the roller granulator 1, and can extrude and granulate the raw material rod 3.

[0027] Working Principle: The organic fertilizer granulator designed in this scheme utilizes the coordinated operation of three components: the material bar conveyor belt 5, the material bar transfer assembly 6, and the material bar unloading assembly 7. First, the material bar conveyor belt 5 is the starting point of the feeding process. Organic fertilizer raw material bars 3 are placed on the material bar conveyor belt 5 at equal intervals on top of the anti-accumulation feeder 2. When the material bar conveyor belt 5 starts, the raw material bars 3 can be smoothly conveyed towards the material bar transfer assembly 6. When the raw material bars 3 reach the material bar transfer assembly 6, the transfer rollers 13 inside the material bar transfer box 11 begin to rotate under the drive of the drive motor 17. The rotation of the transfer rollers 13 pushes... The moving raw material bar 3 moves forward along the first guide plate 14 inside the bar transfer box 11. The inclined design of the first guide plate 14 helps guide the raw material bar 3 to move towards the discharge port 16 of the bar transfer box 11. At the same time, the second guide plate 15 at the bottom of the bar transfer box 11 also guides the movement of the raw material bar 3, so that it can be smoothly discharged from the discharge port 16. The discharged raw material bar 3 falls accurately into the bar feeding assembly 7 below, that is, the input end of the chain plate conveyor 10. The chain plate conveyor 10 can transport the raw material bar 3 to the unloading hopper 9, and then evenly feed the raw material bar 3 into the feed port 18 of the roller press granulator 1.
