Description

Technical Field

[0001] The utility model relates to the field of magnesium oxide grinding devices, in particular to a high-temperature calcining grinding device. Background Art

[0002] Magnesium oxide is an inorganic compound, an oxide of magnesium, an ionic compound, a white solid at room temperature, existing in nature in the form of periclase, and is the raw material for magnesium smelting. It has high fire-resistant insulation properties and can be transformed into crystals after high-temperature burning above 1000°C. When the temperature rises to 1500-2000°C, it becomes dead-burned magnesium oxide (magnesia) or sintered magnesium oxide. The grinding operation of magnesium oxide is completed through the relative movement of the grinding tool and the workpiece under a certain pressure.

[0003] After an in-depth analysis of the mentioned patent application number 201821560522.7, the patent is named "A medium stirred mill for grinding magnesium oxide". Its core is to enhance the grinding effect of magnesium oxide through a specific stirring mechanism. According to this design, magnesium oxide is fed into the stirring barrel through a feed pipe, and then under the precise control of the controller, the stirring motor starts to drive the rotating shaft and the stirring shaft to rotate. The interaction between this rotational motion and the grinding balls can theoretically produce a good stirring effect to ensure uniform mixing of the materials.

[0004] However, in actual applications, although the uniformity of stirring is improved to a certain extent, the improvement in grinding efficiency is relatively limited. Simply relying on stirring operations to enhance the grinding effect is obviously unable to meet the current demand for high-efficiency grinding. Therefore, in order to further improve the grinding efficiency and overall processing quality of magnesium oxide, we urgently need to develop a new type of magnesium oxide grinding device with higher grinding efficiency. Such a device can not only significantly increase the grinding speed, but also achieve a finer grinding effect while maintaining uniformity. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a high-temperature calcination grinding device to solve the technical problem of low effect on enhancing grinding efficiency in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature calcination grinding device, comprising a device body, a grinding cylinder is arranged on the top of the device body, a grinding chamber is arranged on the bottom of the grinding cylinder, a medium is arranged inside the grinding chamber, two transmission rods are arranged above the inside of the grinding cylinder, a stirring rod is arranged at the bottom of the transmission rod, a first motor is arranged on the top of the stirring rod, a heating base is arranged on the outside of the grinding chamber, and a control panel is arranged on the front surface of the device body.

[0007] By adopting the above technical solution, heating provides the necessary energy for the grinding process, which accelerates the movement of magnesium oxide molecules and increases the collision frequency. This heating effect promotes the rate of physical changes and chemical reactions, which helps to achieve the desired grinding effect more quickly. By increasing the activity between molecules, heating significantly improves the grinding efficiency and shortens the time required to achieve the ideal fineness.

[0008] Furthermore, the medium is a grinding ball, and a plurality of the grinding balls are provided. The medium has two but not limited to two size and structural forms.

[0009] By adopting the above technical solution, large-sized grinding balls have greater impact force and grinding area, which can quickly break large pieces of magnesium oxide into smaller particles, while small-sized grinding balls can grind these smaller particles more finely to achieve the required fineness. Therefore, the combination of grinding balls of various sizes can cover a wider range of grinding needs and improve grinding efficiency and effects.

[0010] Furthermore, the grinding chamber is made of a ceramic lining, three stirring rods are provided and arranged in an equidistant ring, and the first motor is connected to the transmission rod through a gear box.

[0011] By adopting the above technical solution, the grinding chamber with ceramic lining has good wear resistance and corrosion resistance, and can maintain the stability and cleanliness of the grinding environment for a long time. The ceramic material also has high hardness and impact resistance, and can effectively resist the friction and impact force generated during the grinding process, thereby extending the service life of the grinding chamber. The gearbox is in a state where three gears are meshed with each other.

[0012] Furthermore, a discharge chamber is provided at the bottom of the grinding chamber, a discharge chamber is provided on one side of the discharge chamber, and spiral blades are provided inside the discharge chamber.

[0013] By adopting the above technical solution, the ground materials can be effectively collected, and the ground materials naturally fall into the discharge chamber under the action of gravity, which is convenient for centralized management and subsequent processing.

[0014] Furthermore, one side of the discharge cavity passes through the device body and is provided with a discharge port, and one side of the discharge port is provided with a second motor, and the second motor is used for the operation of the spiral blades.

[0015] By adopting the above technical solution, the discharge port allows the material after grinding to be discharged smoothly from the inside of the equipment, which not only simplifies the material discharge path, but also effectively reduces the resistance and friction of the material during the discharge process, thereby improving the discharge efficiency.

[0016] Furthermore, a feed port is provided on one side of the top of the grinding cylinder, and the feed port is a welding flange.

[0017] By adopting the above technical solution, the feed inlet can conveniently add the material to be ground into the grinding chamber. This layout makes the material adding process more intuitive and convenient, and improves the operating efficiency.

[0018] Furthermore, a cooling module is provided outside the discharge cavity, and the cooling module is used to cool the raw materials.

[0019] By adopting the above technical solution, the cooling module can effectively reduce the temperature of the raw materials. During the grinding process, the raw materials will generate heat due to friction and collision, and the heat conduction operation of the heating base will cause the temperature to rise. Through the action of the cooling module, the temperature of the raw materials can be quickly reduced to an appropriate range to ensure the grinding effect and product quality.

[0020] Furthermore, a plurality of cold water pipes are arranged inside the cooling module, and the cold water pipes are connected to an external liquid storage device through a liquid pump.

[0021] By adopting the above technical solution, the raw material to be cooled can be cooled evenly and efficiently. Cold water circulates in the cold water pipe, continuously absorbing and taking away the heat generated during the grinding process, thereby effectively reducing the temperature of the raw material and ensuring that it maintains stable performance during the grinding process.

[0022] Furthermore, the control panel includes a temperature control module, a grinding control module, a cooling control module and a discharge control module.

[0023] By adopting the above technical solution, the control panel can accurately control the heating base, which can avoid adverse conditions such as thermal decomposition and phase change of magnesium oxide due to excessively high temperature during the grinding process. These conditions will seriously affect the physical and chemical properties of magnesium oxide, thereby reducing the grinding effect and product quality. By accurately controlling the heating temperature and time, it can be ensured that magnesium oxide is ground within the optimal temperature range to maintain its stability and purity.

[0024] Furthermore, a filter screen is arranged above the interior of the discharge cavity.

[0025] By adopting the above technical solution, impurities generated during the grinding process and incompletely ground materials with larger particles can be effectively filtered out, thus ensuring that the particle size of the material discharged from the discharge chamber is uniform and improving the purity and quality of the product.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model uses a heating base, and heating has a significant effect on the grinding process. By providing energy, heating accelerates the movement of magnesium oxide molecules and increases the collision frequency. This molecular-level activity promotes physical changes in the grinding process, so that the raw materials can reach the required fineness and uniformity faster. Therefore, heating not only accelerates the grinding speed, but also helps to improve the grinding effect and ensure the quality of the final product. At the same time, heating also has a positive effect on the physical properties of magnesium oxide. Under heating conditions, the hardness of magnesium oxide is reduced, making it easier to grind. This change significantly reduces the energy and time required for grinding, thereby improving the overall grinding efficiency. In addition, heating also helps to promote the uniform distribution of magnesium oxide particles and avoids the occurrence of particle agglomeration. This uniformity not only improves the fineness of the product, but also lays the foundation for its performance stability in subsequent applications. It not only improves the grinding speed, but also ensures the quality and uniformity of the final product.

[0028] 2. The utility model can effectively avoid thermal decomposition, phase change and other conditions that may occur in the grinding process of magnesium oxide by setting a control panel. The precise adjustment of the heating base by the control panel can ensure that the magnesium oxide is ground within an appropriate temperature range, thereby preventing the change of chemical or physical properties due to excessive temperature, thereby ensuring the stability of grinding and product quality. At the same time, the precise control of the cooling module by the control panel can prevent the sintering, thermal stress cracking and other problems of magnesium oxide due to excessive temperature during the grinding process. This control ensures the timeliness and effectiveness of the cooling effect, avoids the adverse effects of high temperature on magnesium oxide grinding, and thus improves the grinding accuracy and efficiency.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A high temperature calcination grinding device, such as Figure 1-Figure 4 As shown, the device comprises a main body 1, a grinding cylinder 2 is arranged on the top of the main body 1, a grinding chamber 4 is arranged on the bottom of the grinding cylinder 2, a medium 5 is arranged inside the grinding chamber 4, two transmission rods 3 are arranged above the inside of the grinding cylinder 2, a stirring rod 6 is arranged at the bottom of the transmission rod 3, a first motor 7 is arranged on the top of the stirring rod 6, a heating base 8 is arranged on the outside of the grinding chamber 4, and a control panel 9 is arranged on the front surface of the main body 1. Heating provides the necessary energy for the grinding process, so that the movement between magnesium oxide molecules is accelerated and the collision frequency is increased. This heating effect promotes the rate of physical changes and chemical reactions, which helps to achieve the desired grinding effect faster. By increasing the activity between molecules, heating significantly improves the grinding efficiency and shortens the time required to achieve the ideal fineness. At the same time, heating also reduces the hardness of magnesium oxide, making it easier to grind. The reduction in hardness reduces the energy and time required in the grinding process, further improving the grinding efficiency. In addition, heating promotes the uniform distribution of magnesium oxide particles and avoids the occurrence of particle agglomeration.

[0038] See also Figure 3The medium 5 is a grinding ball, and a plurality of the grinding balls are provided. The medium 5 is of two but not limited to two size structures. The large-sized grinding balls have a larger impact force and grinding area, and can quickly break large pieces of magnesium oxide into smaller particles, while the small-sized grinding balls can grind these smaller particles more finely to achieve the required fineness. Therefore, the combination of grinding balls of various sizes can cover a wider range of grinding needs and improve grinding efficiency and effects. At the same time, grinding balls of various sizes can also help reduce energy consumption and time costs in the grinding process. Since large-sized grinding balls and small-sized grinding balls each have different advantages, they can complement each other in the grinding process, thereby reducing the overall energy and time required.

[0039] See also Figure 2 , Figure 3 The grinding chamber 4 is made of a ceramic lining, and three stirring rods 6 are arranged in an equidistant ring. The grinding chamber 4 with a ceramic lining has good wear resistance and corrosion resistance, and can maintain the stability and cleanliness of the grinding environment for a long time. The ceramic material also has high hardness and impact resistance, and can effectively resist the friction and impact force generated during the grinding process, thereby extending the service life of the grinding chamber 4. At the same time, the three stirring rods 6 are arranged in an equidistant ring, so that the materials in the grinding process can be more evenly and fully stirred. This layout not only improves the stirring efficiency, but also promotes the contact and collision between the materials and the grinding balls, thereby accelerating the grinding speed.

[0040] See also Figure 2 , Figure 3 , Figure 4 A discharge chamber 11 is provided at the bottom of the grinding chamber 4, and a discharge chamber 12 is provided on one side of the discharge chamber 11. A spiral blade 13 is provided inside the discharge chamber 12, which can effectively collect the ground materials. The ground materials naturally fall to the discharge chamber 11 under the action of gravity, which is convenient for centralized management and subsequent processing. At the same time, the discharge chamber 12 is adjacent to the discharge chamber 11, and the spiral blades 13 equipped inside can transport the materials in an orderly manner. The rotational movement of the spiral blades 13 can ensure that the materials move smoothly and continuously from the discharge chamber 11 to the discharge chamber 12, and are finally discharged through the discharge port, avoiding blockage and retention of materials during the discharge process.

[0041] See also Figure 2 , Figure 3 , Figure 4One side of the discharge chamber 12 passes through the device body 1 and is provided with a discharge port 14. A second motor 15 is provided on one side of the discharge port 14. The second motor 15 is used for the operation of the spiral blade 13. The discharge port 14 allows the material after grinding to be discharged smoothly from the inside of the equipment, which not only simplifies the material discharge path, but also effectively reduces the resistance and friction of the material during the discharge process, thereby improving the discharge efficiency. At the same time, the setting of the second motor 15 provides power guarantee for the operation of the spiral blade 13. The spiral blade 13 can rotate stably and efficiently under the drive of the second motor 15, thereby smoothly transporting the material from the discharge chamber 11 through the discharge chamber 12 to the discharge port 14.

[0042] See also Figure 2 , Figure 3 , Figure 4 A feed port 10 is provided on one side of the top of the grinding cylinder 2. The feed port 10 is a welding flange. The feed port 10 can conveniently add the material to be ground into the grinding chamber 4. This layout makes the material adding process more intuitive and convenient, and improves the operating efficiency. At the same time, the use of a welding flange as the connection method of the feed port 10 ensures the firmness and sealing of the connection. The welding flange has high strength and stability, can withstand the vibration and impact force generated during the grinding process, and has good connectivity and sealing, which improves the convenience of transportation of magnesium oxide raw materials.

[0043] See also Figure 2 , Figure 3 , Figure 4 A cooling module 16 is provided on the outside of the discharge chamber 12. The cooling module 16 is used to cool the raw materials. The cooling module 16 can effectively reduce the temperature of the raw materials. During the grinding process, the raw materials will generate heat due to friction and collision, and the heat conduction operation of the heating base 8 will cause the temperature to rise. Through the action of the cooling module 16, the temperature of the raw materials can be quickly reduced to an appropriate range to ensure the grinding effect and product quality. At the same time, the cooling module 16 also helps to improve the grinding efficiency. The reduction in the temperature of the raw materials can reduce its thermal expansion and softening during the grinding process, which is conducive to the effective crushing and refinement of the raw materials by the grinding balls, thereby improving the grinding speed and efficiency.

[0044] See also Figure 4The interior of the cooling module 16 is provided with a plurality of cold water pipes 17, and the cold water pipes 17 are connected with an external liquid storage device through a liquid pump, so as to realize uniform and efficient cooling of the raw material to be cooled. The cold water circulates in the cold water pipes 17, continuously absorbing and taking away the heat generated in the grinding process, thereby effectively reducing the temperature of the raw material and ensuring that it maintains stable performance during the grinding process. At the same time, the connection between the liquid pump and the external liquid storage device not only ensures the continuous supply of cold water, but also can adjust the cooling effect according to actual needs. By controlling the working state of the liquid pump and the temperature, flow rate and other parameters of the cold water in the liquid storage device, the cooling capacity of the cooling module 16 can be flexibly adjusted to meet the cooling requirements under different grinding conditions.

[0045] Embodiment 2:

[0046] See also Figure 1 The control panel 9 includes a temperature control module 901, a grinding control module 902, a cooling control module 903 and a discharging control module 904. The precise control of the heating base 8 by the control panel 9 can avoid adverse conditions such as thermal decomposition and phase change of magnesium oxide due to excessive temperature during the grinding process. These conditions will seriously affect the physical and chemical properties of magnesium oxide, thereby reducing the grinding effect and product quality. By accurately controlling the heating temperature and time, it can be ensured that magnesium oxide is ground within the optimal temperature range to maintain its stability and purity. At the same time, the precise control of the cooling module 16 by the control panel 9 can also effectively prevent sintering, thermal stress cracking and other problems caused by excessive temperature during the grinding process of magnesium oxide. These problems will not only affect the grinding effect, but may also cause equipment damage and production interruption. Through timely and effective cooling, the hardness and brittleness of magnesium oxide can be maintained, which is conducive to the crushing and refinement of the grinding balls, thereby improving the grinding accuracy and efficiency.

[0047] See also Figure 2 , Figure 3 , Figure 4 A filter screen 18 is arranged above the inside of the discharge chamber 11, which can effectively filter out impurities generated during the grinding process and incompletely ground materials with larger particles. This can ensure that the particle size of the material discharged from the discharge chamber 11 is uniform, thereby improving the purity and quality of the product. At the same time, the presence of the filter screen 18 can also protect subsequent processing equipment from damage by large particles and extend the service life of the equipment.

[0048] The implementation principle of the utility model is as follows: first, the raw material is put into the interior of the grinding cylinder 2 through the feed port 10, and then the temperature control module 901 and the grinding control module 902 are controlled so that the stirring rod 6 grinds the medium 5 and the magnesium oxide, and the heating base 8 is used to heat the raw material inside the grinding chamber 4. The heating can provide energy to accelerate the movement between the magnesium oxide molecules and increase the collision frequency between the molecules, thereby accelerating the physical changes and chemical reaction rates during the grinding process, which helps to achieve the desired grinding effect more quickly. Secondly, under the heating condition, the hardness of the magnesium oxide will decrease and it will become easier to grind, which can reduce the energy and time required in the grinding process and improve the grinding efficiency. In addition, heating can promote the uniform distribution of the magnesium oxide particles and avoid the occurrence of particle agglomeration, which helps to obtain a more uniform and finer ground product, thereby improving the grinding efficiency and grinding effect of the magnesium oxide.

[0049] After waiting for the grinding to be completed, the cooling control module 903 and the discharge control module 904 are controlled to cause the second motor 15 to drive the spiral blade 13 to rotate, and the ground magnesium oxide inside the discharge chamber 11 and the discharge chamber 12 is uniformly transported. At the same time, the cold water pipe 17 inside the cooling module 16 is used to perform heat exchange operation with the magnesium oxide raw material with a higher temperature inside to reduce the temperature of the magnesium oxide powder until the magnesium oxide is discharged from the discharge port 14, thereby completing the grinding operation of the magnesium oxide;

[0050] The control panel 9 can be used to accurately control the working state and working efficiency of the heating base 8 and the cooling module 16. Through precise control, the thermal decomposition, phase change, sintering, thermal stress cracking and other conditions that may occur in the magnesium oxide during the grinding process can be avoided, thereby improving the grinding accuracy of the magnesium oxide.
