Description

Technical Field

[0001] This application relates to the technical field of material processing, and in particular to an aggregate granulation device. Background Art

[0002] Currently, aggregate (dust material) granulation technology has been widely applied in multiple industrial fields. Among them, the flat die extrusion granulator is favored because of its simple structure and convenient operation.

[0003] During the granulation process of traditional flat die extrusion granulators, since the rotational speeds of the pressure rollers and the flat die are fixed, a simple mechanical crushing method is used to achieve the basic granulation function. However, because the moisture content in the material has a great influence on the pressurization effect of the flat die, it is found that the moisture in the mixed material should be controlled between 8% and 10% for suitability. Existing aggregate granulators lack moisture control, which affects the forming quality of the granules.

[0004] Therefore, based on the above problems, the existing technology needs to be improved. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that the moisture content in the material affects the pressurization effect of the flat die, thereby affecting the granulation efficiency and the quality of the formed granules.

[0006] The above technical purpose of this application is achieved through the following technical solutions: An aggregate granulation device includes a housing. The housing encloses to form a receiving cavity. The housing is provided with a feed inlet. A template is arranged in the receiving cavity. The template is provided with a plurality of die holes. A first transmission shaft passes through the template. The first transmission shaft is connected to a first driving member. A pressure roller is arranged on the first transmission shaft. The pressure roller is driven by the first driving member to move on the template. The housing is provided with a water inlet. A water inlet pipe is arranged at the water inlet. A flow control valve is arranged in the water inlet pipe.

[0007] By adopting the above technical solutions, by precisely controlling the movement of the pressure roller on the template, the pressure can be applied to the material more evenly, so that the produced particles are more uniform and dense, improving the quality and strength of the particles. The arrangement of the water inlet and the water inlet pipe provided with a flow control valve can accurately control the water addition amount during the granulation process, keeping the water content in the material within an appropriate range, which helps to improve the forming effect and stability of the particles. The movement speed and pressure of the pressure roller, as well as the water flow rate of the water inlet pipe, can be flexibly adjusted according to different material characteristics and production requirements to adapt to various production conditions. Precise pressure control and water regulation can reduce the generation of defective products during the granulation process and lower the rework rate, thereby improving the overall production efficiency. Reasonable movement of the pressure roller and precise water control can reduce the working load of the equipment, reduce the wear and failure of components, extend the service life of the equipment, and lower the maintenance cost. The stable and precise granulation process can ensure that the produced aggregate particles have high consistency, meeting the strict requirements of the market for product quality.

[0008] Optionally, a nozzle is provided at the water inlet, the nozzle is connected to the water inlet pipe, and the flow control valve is arranged at the connection between the nozzle and the water inlet pipe.

[0009] By adopting the above technical solutions, setting the flow control valve at the connection between the nozzle and the water inlet pipe can individually and precisely control the water flow rate of each nozzle, ensuring that the water can be accurately sprayed to the required position, improving the uniformity of water distribution, and thus optimizing the granulation effect. Precise control of the water flow rate can avoid waste of water resources, save water resources to the greatest extent on the premise of meeting the water requirements for granulation, and reduce production costs. By separately controlling the flow rates of different nozzles, multiple water spraying modes can be achieved to adapt to the needs of different types of materials and granulation processes, increasing the versatility and flexibility of the device. Precise water spraying control helps to maintain the consistency of water conditions during each granulation process, thereby improving the stability of particle quality and reducing defective products caused by uneven water distribution. Reasonable control of the water spraying flow rate can prevent excessive water from entering the interior of the equipment, reduce the risk of equipment failure due to water accumulation or waterlogging, and improve the reliability of equipment operation.

[0010] Optionally, a plurality of nozzles are provided, and the plurality of nozzles are evenly spaced around the template.

[0011] By adopting the above technical solutions, the uniform spaced distribution of multiple nozzles can ensure more uniform spraying of water on the template, enabling the material to receive appropriate and uniform moisture supplementation at each position, thereby improving the consistency and quality of particle forming. The template is covered comprehensively to avoid water spraying dead angles, allowing the material to receive effective moisture regulation throughout the granulation area and further enhancing the granulation effect. Uniform and comprehensive water spraying can accelerate the granulation process, shorten the granulation time, and thus improve production efficiency. The uniform moisture distribution creates stable conditions for granulation, reducing the quality fluctuations of particles caused by local moisture differences and ensuring the stability of product quality. Regardless of the distribution of the material on the template, multiple uniformly distributed nozzles can effectively add moisture, enhancing the adaptability of the device to different material distribution situations. Since the water spraying is more uniform and efficient, unnecessary moisture addition can be reduced, thereby reducing energy consumption and water resource consumption to a certain extent.

[0012] Optionally, an installation member is provided in the accommodating cavity, a vibration platform is provided on the installation member, and the template is arranged on the vibration platform.

[0013] By adopting the above technical solutions, the vibration effect of the vibration platform can enable the formed particles to be quickly discharged from the template, improving the discharging efficiency of the product. Continuous vibration can prevent particles from accumulating or blocking the die holes on the template, ensuring the smooth progress of the granulation process and reducing production interruptions. Vibration helps the material to be more evenly distributed on the template, making the extrusion of the material by the pressure rollers more uniform, thereby improving the consistency of the particles. The vibration causes the particles to quickly separate from the template and be discharged orderly, accelerating the discharging speed and improving production efficiency. Appropriate vibration can improve the shape and structure of the particles, making them more dense and regular and enhancing the performance of the particles.

[0014] Optionally, a plurality of pressure rollers are provided, and the plurality of pressure rollers are evenly spaced on the first transmission shaft.

[0015] By adopting the above technical solutions, the uniform spaced arrangement of multiple pressure rollers can simultaneously extrude more materials, increasing the processing capacity per unit time, thereby significantly improving the efficiency of extrusion granulation. The uniformly distributed pressure rollers can make the material receive more uniform pressure on the template, ensuring that the produced particles are more consistent in density and shape and improving the stability of product quality. The uniform spacing of multiple pressure rollers helps to balance the load borne by the first transmission shaft, reducing the wear or deformation of the transmission shaft caused by excessive local stress and extending the service life of the transmission shaft. A reasonable layout of the pressure rollers can guide the material to flow more smoothly on the template, reducing the possibility of material accumulation and blockage and ensuring the continuity of the granulation process. For materials with different properties and particle size distributions, multiple uniformly arranged pressure rollers can better adapt to and effectively extrude them, broadening the applicable range of the device to materials.

[0016] Optionally, the pressing roller includes a roller shaft fixedly connected to the first transmission shaft, and a roller is sleeved on the roller shaft.

[0017] By adopting the above technical solution, when the roller is worn or damaged, only the roller needs to be replaced separately, without replacing the entire pressing roller, including the part fixedly connected to the transmission shaft, reducing the maintenance cost and repair time. Different rollers made of different materials, with different sizes or surface characteristics can be selected and sleeved on the roller shaft according to different granulation requirements to adapt to different materials and process requirements, increasing the flexibility and versatility of the device. The design of the roller shaft can be standardized, and different rollers are matched with it, reducing the types and specifications of parts, which is convenient for production, inventory management and equipment assembly.

[0018] Optionally, it further includes a cutting assembly, which is arranged on the side of the template away from the feed port. The cutting assembly includes a second driving member arranged on the template, a second transmission shaft is arranged on the second driving member, a cutter is arranged on the second transmission shaft, and the cutter abuts against the template, and the cutter is driven by the second driving member to move relative to the template.

[0019] By adopting the above technical solution, the movement of the cutter relative to the template can be accurately controlled by the second driving member, enabling accurate cutting of the extruded material, ensuring that the length or size of the particles meets the requirements, and improving the consistency and quality of the product. The automated cutting process can perform cutting operations quickly and continuously. Compared with manual or inefficient cutting methods, the production efficiency is greatly improved. Precise cutting can reduce material waste caused by inaccurate cutting, improve the utilization rate of raw materials, and reduce production costs. The parameters of the second driving member can be flexibly adjusted according to production requirements, thereby changing the movement speed, cutting frequency, etc. of the cutter to adapt to the production requirements of different specifications of particles.

[0020] Optionally, it further includes a hopper, which is arranged in the accommodating cavity, and a discharge port is arranged on the outer shell.

[0021] By adopting the above technical solution, the hopper can quickly collect the formed bone particles, avoid waste caused by the scattering of bone particles and the chaos of the production environment, and improve the collection efficiency. Ensure that the bone particles are discharged from the hopper in an orderly manner, which is convenient for subsequent transportation, packaging or further processing, making the entire production process smoother. It can store the formed bone particles to a certain extent and play a buffering role. Even if the granulation speed does not match the speed of the subsequent processing link, the continuity of production can be ensured. Catch the bone particles and control the discharging process, reducing the collision and wear of the bone particles during the falling process, and protecting the integrity and quality of the bone particles. The hopper can be used as a metering container, which is convenient for counting the number of produced bone particles, beneficial to production management and quality control. Concentrate the formed bone particles in the hopper, which is convenient for unified management and monitoring of the output of bone particles, and timely discover problems in production.

[0022] In summary, the present application has at least the following beneficial effects:

[0023] 1. By adopting a water spraying system and a flow control valve, precise control of the water content during the aggregate granulation process is achieved, ensuring the quality of particle forming.

[0024] 2. The preferred vibration platform and evenly arranged nozzles promote the uniformity of particles and reduce the risk of blockage. Meanwhile, the setting of multiple pressure rollers improves the overall processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following further details the present application with reference to the accompanying drawings.

[0031] In this embodiment, referring to Figures 1-3 , an aggregate granulation device includes a housing 1, and the housing 1 constructs a closed accommodation chamber 2. A feed inlet 3 is provided on the housing 1 to facilitate the continuous input of aggregates. Inside the accommodation chamber 2, a template 4 is installed, and a plurality of die holes 5 are arranged on the template 4, providing necessary channels for the forming of aggregates. A first transmission shaft 6 penetrates through the center position of the template 4, and the first transmission shaft 6 is in transmission connection with a first driving member 7, enabling smooth rotation through the first driving member 7. A plurality of pressure rollers 8 are fixed on the first transmission shaft 6, and the plurality of pressure rollers 8 move along with the rotation of the shaft, applying uniform pressure to the material on the template 4, and promoting the material to form particles through the die holes 5 on the template 4. A water inlet 9 is also configured on the housing 1, connected to a water inlet pipe 10, and an adjustable flow control valve 11 is installed in the water inlet pipe 10 to achieve accurate control of the water spraying amount.

[0032] The implementation principle of Embodiment 1 is as follows: During use, the aggregate (powder material) enters the accommodation chamber 2 through the feed inlet 3, causing the material to be evenly spread on the template 4. The first driving member 7 drives the first transmission shaft 6 to rotate, and the pressing roller 8 driven by the first transmission shaft 6 rolls on the template 4. The material is squeezed into the die holes 5 on the template 4, and the pressing roller 8 continuously presses on the aggregate spread on the hole template 4. The aggregate is forced to be extruded from the openings of the template 4 in the wedge-shaped area formed by the template 4 and the pressing roller 8. During this process, an appropriate amount of water is sprayed through the water inlet 9 to adjust the moisture content of the material and ensure that the material is in the best molding state. The flow control valve 11 can adjust the water spray amount according to the actual situation, thereby achieving the purpose of optimizing the particle quality.

[0033] Embodiment 2

[0034] The difference in this embodiment is that, referring to Figure 2 , a special nozzle 12 is assembled at the water inlet 9. The nozzle 12 is exquisitely connected to the water inlet pipe 10, and a flow control valve 11 is provided at the interface between the nozzle 12 and the water inlet pipe 10. This configuration further improves the accuracy and efficiency of water spraying, enabling the device to better meet the requirements of different materials and processing conditions. Further improvements have been made to the water spraying system. Specifically, the number of nozzles 12 is increased to multiple, and they are evenly distributed around the template 4 to ensure that the material in every corner can obtain uniform moisture supply. This improvement significantly improves the uniformity and molding quality of the particles.

[0035] Embodiment 3

[0036] Referring to Figures 2-3 , in this embodiment, a mounting member 13 is added in the accommodation chamber 2. A vibration platform 14 is fixed on the mounting member 13, and the template 4 is firmly placed on the vibration platform 14. By introducing the vibration function, the device can not only improve the uniformity of the particles but also effectively prevent blockage, thus ensuring a continuous and efficient production process.

[0037] Embodiment 4

[0038] In this embodiment, referring to Figure 2 , the design of the pressing roller 8 is optimized. Specifically, multiple pressing rollers 8 are designed to be installable, and they are evenly distributed on the first transmission shaft 6. Each pressing roller 8 consists of a roller shaft 81 and a roller wheel 82. The roller shaft 81 is rigidly connected to the first transmission shaft 6, and the roller wheel 82 can be flexibly sleeved on the roller shaft 81. This split design not only improves the durability of the pressing roller 8 but also makes replacement and maintenance more convenient.

[0039] Embodiment 5

[0040] Referring to Figures 2-3, in this embodiment, a cutting component 15 is introduced into the device, and this component is cleverly arranged at one end of the template 4 away from the feed port 3. The cutting device includes a second driving member 151, a second transmission shaft 152, and a cutting knife 153. The initial position of the cutting knife 153 avoids the die hole 5. After the material is extruded from the die hole 5, through the precise control of the second driving member 151, the second transmission shaft 152 drives the cutting knife 153 to move closely along the surface of the template 4, that is, the cutting knife 153 rotates along the central position of the template 4. The cutting knife 153 cuts the formed material extruded from the die hole 5, thereby ensuring that the produced particles have a consistent length, significantly improving the standardization degree and market competitiveness of the product.

[0041] Embodiment 6

[0042] Refer to Figures 1-2 , considering the convenience of particle collection and output, in this embodiment, a hopper 16 is added in the accommodating cavity 2, and a discharge port 17 is opened on the housing 1. The processed particles will naturally fall into the hopper 16 and then be conveniently output through the discharge port 17. This design greatly simplifies the subsequent processing process of the particles and improves the production efficiency.

[0043] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
