Description

Technical Field

[0001] This utility model relates to the field of raw material processing technology, and more specifically, to a raw material crushing device with adaptable grinding parameters. Background Technology

[0002] In the raw material processing industry, traditional equipment has many drawbacks. Regarding particle size classification and raw material differentiation, most traditional devices have limited capabilities, only able to process raw materials into a few particle sizes, making it difficult to meet diverse production needs. For example, in electronic material production, this field has extremely high requirements for raw material particle size precision, but traditional equipment often provides raw materials with particle sizes that do not meet standards, leading to poor product performance. In cosmetics manufacturing, differences in the particle size of different raw materials affect product texture and efficacy, but traditional equipment performs poorly in fine processing.

[0003] From an energy utilization perspective, traditional equipment suffers from widespread energy waste due to the lack of precise particle size classification and raw material differentiation mechanisms. For example, in ceramic production, the demand for raw materials of different particle sizes cannot be effectively matched, resulting in a large amount of energy being consumed in excessive or unreasonable crushing processes, leading to persistently high production costs.

[0004] The structure and working principle of traditional equipment determine its lack of precision in raw material screening and distribution. Common equipment often employs simple screening methods, which not only struggle to accurately separate raw materials of different particle sizes, resulting in uneven product particle size distribution and affecting subsequent production quality and efficiency, but also completely fail to distinguish between different raw materials of the same particle size. The grinding parameters of traditional crushers are difficult to adjust flexibly according to the characteristics of the raw materials. Faced with raw materials of varying hardness and texture, they either suffer from low crushing efficiency or over-crushing, damaging the original properties of the raw materials. Furthermore, existing equipment has a low level of automation, making it difficult for operators to monitor and control equipment operating parameters in real time, resulting in poor product quality stability.

[0005] In industries such as pharmaceuticals and food, where the quality requirements for raw materials are extremely stringent, the limitations of traditional equipment are even more pronounced. In pharmaceutical production, differences in the particle size and composition of raw materials can alter the drug's dissolution rate and efficacy; in food processing, substandard particle size of raw materials can affect taste and nutritional content.

[0006] In conclusion, the development of a device that can classify multiple particle sizes and distinguish raw materials of the same particle size, while also achieving automated feeding, precise grinding parameter adaptation, and energy saving, has become an urgent need for the industry.

[0023] 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.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-3 As shown, this utility model provides a raw material crushing device with adaptable grinding parameters, including: a first roller conveyor 3, a second roller conveyor 4, and a third roller conveyor 5, which are arranged in a multi-level layer on a frame 2. The spacing between adjacent rollers in the first roller conveyor 3, the spacing between adjacent rollers in the second roller conveyor 4, and the spacing between adjacent rollers in the third roller conveyor 5 are sequentially increasing; three sets of conveyor belts 9, which are located below the first roller conveyor 3, the second roller conveyor 4, and the third roller conveyor 5, respectively; three sets of spiral guide tubes 12, each with a connecting hopper 11 connected to its top. The connecting hopper 11 is located below the conveyor belts 9 to facilitate the conveying of raw materials into the spiral guide tubes 12. A gravity sensor 16 is installed below the spiral guide tubes 12; and three sets of mills 14, whose inlets 15 are connected to the outlets of the spiral guide tubes 12.

[0026] The top of the frame 2 is fixedly connected to a multi-level layered conveyor assembly, namely a first roller conveyor 3, a second roller conveyor 4, and a third roller conveyor 5. The first roller conveyor 3, the second roller conveyor 4, and the third roller conveyor 5 are arranged in a stepped manner, that is, the second roller conveyor 4 is below the end of the first roller conveyor 3, and the third roller conveyor 5 is below the end of the second roller conveyor 4. The spacing between adjacent rollers on the first roller conveyor 3 is smaller than the spacing between adjacent rollers on the second roller conveyor 4, and the spacing between adjacent rollers on the second roller conveyor 4 is smaller than the spacing between adjacent rollers on the third roller conveyor 5. The spacing on the three roller conveyors increases progressively. Small-diameter raw materials will fall through the gaps on the first roller conveyor 3, medium-diameter raw materials will fall through the gaps on the second roller conveyor 4, and large-diameter raw materials will fall through the gaps on the third roller conveyor 5, thus achieving the separation of raw materials of different particle sizes.

[0027] The transmission system of the roller conveyor adopts a three-stage transmission structure of "motor-gear-chain". The first roller conveyor 3 has a first motor 6 mounted on one side, driving it. The second roller conveyor 4 has a second motor 7 mounted on one side, driving it. The third roller conveyor 5 has a third motor 8 mounted on one side, driving it. All three motors are mounted on the frame 2. Taking the first roller conveyor 3 as an example, the output shaft of the first motor 6 is connected to the driving gear. The chain is fitted onto the driving and driven gears, forming a closed-loop transmission. The driven gear is fixed to the roller shaft, driving the first roller conveyor 3. The operation of the roller conveyor via motors, gears, and chains is existing technology and will not be elaborated upon here.

[0028] Three sets of conveyor belts 9 are respectively distributed below the first roller conveyor 3, the second roller conveyor 4 and the third roller conveyor 5. The conveyor belts 9 are installed on the frame 2 and driven by the fourth motor 10. The fourth motor 10 driving the conveyor belts 9 is also a prior art and will not be described in detail here. The raw materials that have completed particle size separation fall onto the conveyor belts 9 through the gaps between the rollers and are transported to the spiral guide tube 12 through the conveyor belts 9.

[0029] A connecting hopper 11 is provided below the top of the conveyor belt 9. The connecting hopper 11 is in the shape of an inverted cone with an opening at the bottom. The connecting hopper 11 is fixedly installed on the protective cylinder 13. An inlet 15 is provided on the top of the protective cylinder 13. The opening at the bottom of the connecting hopper 11 corresponds to the inlet 15 on the protective cylinder 13. A spiral guide tube 12 is installed inside the protective cylinder 13. The top inlet of the spiral guide tube 12 corresponds to the inlet 15 on the protective cylinder 13. The raw material is transported to the connecting hopper 11 by the conveyor belt 9 and then enters the spiral guide tube 12.

[0030] A gravity sensor 16 is installed below the spiral conduit 12, and a valve is installed at the outlet below the spiral conduit 12. When different raw materials of the same particle size fall, the sensor can detect the difference in gravity of the raw materials and transmit the signal to the main control board. The main control board controls the valve to descend, so as to distinguish different raw materials of the same particle size range and allow the same raw materials of the same particle size range to enter the mill 14 for grinding.

[0031] Three sets of mills 14 are set up to differentiate raw materials of different particle sizes. The mills 14 use existing equipment. The mill 14 corresponding to the first roller conveyor 3 is a grid-type ball mill 14 of model MQG-1530, with a cylinder diameter of 1.5m and a length of 3.0m, suitable for fine grinding of small particles. It is equipped with a variable frequency speed control system, which can adjust the speed (15-30r / min) according to the data of gravity sensor 16. The grid-type discharge structure avoids over-grinding of fine particles and prevents damage to the characteristics of the raw materials. The mill 14 corresponding to the second roller conveyor 4 is a Raymond mill of model YGM-95, with a grinding roller diameter of 950mm, suitable for crushing medium-sized raw materials. It has a built-in analyzer to adjust the finished product particle size (80-325 mesh), and a hydraulic lifting system to automatically adjust the grinding pressure to adapt to raw materials of different hardness. The mill 14 corresponding to the third roller conveyor 5 is a medium-speed coal mill of model ZGM-113G with a grinding disc diameter of 1130mm, which is suitable for the initial crushing of large-particle raw materials; the rotation speed is 14-25r / min, and the crushing force can be adjusted in real time by receiving the signal from the gravity sensor 16 through the PLC control system; the vertical structure saves space and has high crushing efficiency (processing capacity of 10-30t / h), which can improve crushing efficiency.

[0032] The valves are connected to the main control board, which, as the core control component of the device, is connected to the gravity sensor 16. This allows the main control board to collect real-time information such as the raw material feed rate, the conveyor belt 9 transmission speed, and the operating parameters of the mill 14. The main control board can adjust the material discharge rate of the material bin 1, the conveyor belt 9 transmission speed, and the grinding parameters of the mill 14, such as rotational speed, grinding time, and crushing force. For example, when an increased feed rate is detected, the main control board automatically increases the conveyor belt 9 transmission speed to ensure timely delivery of the raw material. If the raw material in a mill 14 has high hardness, the main control board automatically increases its rotational speed and extends the grinding time, thereby achieving precise grinding and avoiding energy waste.

[0033] The first roller conveyor 3 has a material bin 1 at its front end. The material bin 1 is fixedly connected to the frame 2. The bottom of the material bin 1 has an opening and a valve to control the amount of raw material entering.

[0034] Raw materials enter from the material silo 1 and fall onto the first roller conveyor 3 through the outlet. At this time, small-diameter raw materials fall onto the lower conveyor belt 9 through the gaps between the rollers. Medium and large-diameter raw materials are then transported by the first roller conveyor 3 to the second roller conveyor 4. At this time, medium-diameter raw materials fall onto the lower conveyor belt 9 through the gaps between the rollers. Large-diameter raw materials are then transported by the second roller conveyor 4 to the third roller conveyor 5. Large-diameter raw materials fall onto the lower conveyor belt 9 through the gaps between the rollers. This process achieves the grading of raw materials into small, medium, and large sizes, meeting the diverse needs of different production stages for raw material particle size.

[0035] Each set of conveyor belts 9 is equipped with a corresponding spiral guide tube 12. A gravity sensor 16 is installed below the spiral guide tube 12. The gravity of the same raw material within the same particle size range has a certain value. When the gravity sensor 16 detects a change in gravity, it indicates that another raw material has entered the spiral guide tube 12. At this time, the valve below the spiral guide tube 12 is controlled by the main control board to block it, which can ensure that the same raw material within the same particle size range enters the mill 14 for grinding.

[0036] In terms of particle size classification, this device achieves differentiation of small, medium, and large particle sizes of raw materials by setting up a first roller conveyor 3, a second roller conveyor 4, and a third roller conveyor 5 with an increasing roller spacing on each conveyor. This overcomes the limitations of traditional equipment in particle size classification and can meet diverse production needs. For differentiating raw materials of the same particle size, a spiral guide tube 12 with an integrated gravity sensor 16 is installed below each set of conveyor belts 9. Based on the gravity differences of different raw materials and under the control of the main control board, it achieves differentiation of different raw materials of the same particle size, a function not available in traditional equipment. For intelligent control, the main control board is connected to various sensors to collect real-time data on equipment operating parameters such as raw material feed speed and conveyor belt 9 transmission speed. This enables automated feeding and precise adaptation of grinding parameters, improving production efficiency and product quality while reducing energy consumption.
