Description

Technical Field

[0001] The invention belongs to the technical field of aluminum ash waste production, in particular to a grinding device for producing calcium aluminate using aluminum ash waste. Background Art

[0002] Aluminum ash waste refers to the by-product produced in the aluminum production process, which contains a certain amount of calcium aluminate and other valuable compounds. Calcium aluminate is an important industrial raw material and is widely used in building materials, refractory materials and other fields. Calcium aluminate can be produced by recycling aluminum ash waste.

[0003] Aluminum ash waste is prone to form lumps during the stacking and transportation process, resulting in uneven distribution during the grinding process, which can easily cause blockage and accumulation of grinding equipment, seriously affecting grinding efficiency and product quality. In addition, the uneven distribution of materials will also lead to increased energy consumption during the grinding process, increased equipment wear, and further increase production costs.

[0004] Secondly, traditional grinding components often have problems such as insufficient grinding and poor uniformity, making it difficult to quickly and efficiently convert aluminum ash waste into fine calcium aluminate powder. Furthermore, traditional grinding devices often lack effective mixing and refining methods, resulting in uneven mixing of materials during the grinding process and insufficient refining, which affects the production efficiency and product quality of calcium aluminate.

[0005] In addition, the dust and moisture problems in the grinding process cannot be ignored. The escape of dust and moisture not only pollutes the working environment, but also may cause damage to the grinding equipment and products.

[0019] The stirring assembly rotates the three motor-driven rotating shafts and the stirring spiral blades, so that the materials form a circulation flow inside the working box, thereby improving the grinding efficiency. The circulation flow helps to fully mix the materials and evenly distribute the grinding media, so that the materials can be more fully refined during the grinding process. The work of the stirring assembly can also promote the heat exchange and chemical reaction between the materials and the grinding media. During the grinding process, friction and collision will occur between the materials and the grinding media, thereby generating heat. The circulation flow of the stirring assembly helps to evenly distribute and quickly transfer the heat, thereby accelerating the generation rate of calcium aluminate.

[0020] The efficient capture of the exhaust hood and the effective blocking of the dustproof net in the vent hole can reduce the escape of dust and moisture during the grinding process, while preventing impurities and dust in the external environment from entering the working box, which not only keeps the grinding environment clean and dry, but also improves the safety and stability of the entire grinding process.

DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] A grinding device for producing calcium aluminate using aluminum ash waste according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0034] like Figures 1 to 8As shown, the embodiment of the present invention provides a grinding device for producing calcium aluminate using aluminum ash waste, comprising: a working box 1, a fixing plate 3 is fixedly connected to one side of the top of the inner cavity of the working box 1, a grinding assembly 4 is arranged on the fixing plate 3, non-through mounting grooves 5 are symmetrically opened in the middle of the two side walls of the inner cavity of the working box 1, a filter assembly 6 is arranged between the two mounting grooves 5, mounting plates 7 are symmetrically fixedly connected to the middle of the two side walls of the inner cavity of the working box 1, and the mounting plates 7 are located above the filter assembly 6, a vibration assembly 8 is arranged on the mounting plate 7, a mounting box 9 is fixedly connected to the lower part of the side wall of the working box 1, and a drying assembly is arranged in the inner cavity of the mounting box 9 10. A stirring assembly 11 is provided at the lower part of the side wall of the inner cavity of the working box body 1, a first exhaust hole 12 is fixedly connected through the middle of the side wall of the working box body 1, a second exhaust hole 13 is fixedly connected through the lower part of the other side wall of the working box body 1, a discharge port 14 is provided at the bottom of the inner cavity of the working box body 1, a feed trough 2 is fixedly connected through the top of the working box body 1, a feed trough cover plate 19 is provided at the top of the feed trough 2, a sealing door 15 is provided on one side of the working box body 1, an observation window 16 is provided on the sealing door 15, electric telescopic rods 17 are fixedly connected to the four corners of the bottom of the working box body 1, and a universal wheel 18 is fixedly connected to the bottom of the electric telescopic rod 17.

[0035] In a specific application of the embodiment of the present invention, first, the aluminum ash waste is fed into the working box 1 through the feed chute 2, and the feed chute cover 19 ensures the sealing during the feeding process, prevents dust leakage, and protects the health and safety of the operator. In the working box 1, the grinding assembly 4 on the fixed plate 3 starts to work, and the grinding assembly 4 grinds the aluminum ash waste into fine particles by rotation and extrusion.

[0036] The ground material falls onto the filter assembly 6 between the two mounting grooves 5. The filter assembly 6 adopts a multi-layer filter structure, which can effectively separate the impurities and fine powder generated during the grinding process to ensure the purity of the subsequent process. At the same time, the design of the filter assembly 6 also takes into account the needs of easy cleaning and replacement to maintain a long-term filtering effect. In order to improve the filtering efficiency, the vibration assembly 8 on the mounting plate 7 starts to work. The vibration assembly 8 generates high-frequency vibrations to help the material be evenly distributed on the filter assembly 6 to prevent clogging.

[0037] The filtered material enters the drying component 10 in the installation box 9 for drying. The drying component 10 quickly removes moisture from the material by heating and ventilation to ensure the smooth progress of subsequent processes. The dried material is more stable and easy to store and transport. The stirring component 11 at the lower part of the inner cavity side wall of the working box 1 starts to work and stirs the dried material. The design of the stirring component 11 fully considers the characteristics of the material and the process requirements to ensure the uniformity and efficiency of stirring.

[0038] During the grinding, filtering, drying and stirring process, the first exhaust hole 12 and the second exhaust hole 13 are always kept open to ensure air circulation in the working box 1, which helps to prevent dust accumulation and explosion risks, and also helps to discharge the generated harmful gases. When the material processing is completed, the material is discharged through the discharge port 14 at the bottom of the inner cavity of the working box 1. The design of the discharge port 14 takes into account the fluidity and discharge speed of the material to ensure smooth and stable discharge.

[0039] During the whole working process, the observation window 16 on the sealing door 15 allows the operator to observe the situation in the working box 1 at any time, so as to adjust the process parameters and eliminate the faults in time. At the same time, the combination of the electric telescopic rod 17 and the universal wheel 18 makes the whole device have good mobility and stability, and can adapt to different sites and process requirements.

[0040] In one embodiment, the vibration assembly 8 includes a motor 2 8.1, a half gear 8.2, a gear 8.3, a connecting rod 8.4, a rotating arm 8.5, and a hammering block 8.6. The motor 2 8.1 is fixedly connected to one side of the mounting plate 7. The output end of the motor 2 8.1 passes through the mounting plate 7 and is fixedly connected to the half gear 8.2, and the half gear 8.2 is rotatably connected to one side of the mounting plate 7. The gear 8.3 is rotatably connected to one side of the mounting plate 7. The gear 8.3 is meshed with the half gear 8.2. One side of the gear 8.3 is fixedly connected to a connecting rod 8.4. One end of the connecting rod 8.4 is fixedly connected to a rotating arm 8.5. One end of the rotating arm 8.5 is fixedly connected to a hammering block 8.6.

[0041] In a specific application of the embodiment of the present invention, when the motor 2 8.1 is started, its output end starts to rotate and drives the half gear 8.2 fixedly connected thereto to rotate synchronously. The half gear 8.2 has only half of its teeth, which makes it only intermittently meshing with the gear 8.3 during the rotation process. The gear 8.3 is rotatably connected to one side of the mounting plate 7 through bearings and other components to maintain a stable rotation state. When the teeth of the half gear 8.2 mesh with the gear 8.3, it will push the gear 8.3 to rotate. Due to the gear ratio and speed difference between the gear 8.3 and the half gear 8.2, the rotation speed of the gear 8.3 will be different from that of the half gear 8.2. As the half gear 8.2 continues to rotate, when its teeth are out of mesh with the gear 8.3, the gear 8.3 will continue to rotate for a distance due to inertia until the next tooth of the half gear 8.2 meshes with it again.

[0042] The periodic rotation of the gear 8.3 is transmitted to the rotating arm 8.5 through the connecting rod 8.4. One end of the connecting rod 8.4 is fixedly connected to the gear 8.3, and the other end is fixedly connected to the rotating arm 8.5 to form a stable transmission chain. As the gear 8.3 rotates, the connecting rod 8.4 drives the rotating arm 8.5 to swing. One end of the rotating arm 8.5 is fixedly connected with a hammer block 8.6. When the rotating arm 8.5 swings, the hammer block 8.6 moves up and down and hammers and vibrates the materials above the filter assembly 6. This hammering and vibration can effectively destroy the bonding force between the materials, making them looser and more evenly distributed, thereby improving the filtering effect and grinding efficiency.

[0043] In one embodiment, the filter assembly 6 includes a spring 6.1, a connecting plate 6.2, a filter screen plate 6.3, and a filter screen 6.4. A plurality of springs 6.1 are evenly and fixedly connected to the bottom of the inner cavity of the installation groove 5, a connecting plate 6.2 is fixedly connected to the top of the spring 6.1, and the two facing sides of the two connecting plates 6.2 are respectively fixedly connected to the two side walls of the filter screen plate 6.3. A through groove is opened on the top of the filter screen plate 6.3, and a filter screen 6.4 is fixedly connected to the inner cavity of the through groove.

[0044] In the specific application of the embodiment of the present invention, the ground materials fall from the top of the working box 1 into the area of ​​the filter assembly 6. After the preliminary grinding process, the particle size of these materials has been greatly reduced, but they still need to be further screened to remove impurities and excessively fine powder. At this time, the materials contact the filter screen plate 6.3, and the two side walls of the filter screen plate 6.3 are fixedly connected to the spring 6.1 in the installation groove 5 through the connecting plate 6.2. The spring 6.1 not only provides stable support for the filter screen plate 6.3, but also gives the filter screen plate 6.3 a certain elasticity and buffering capacity.

[0045] When the material is accumulated on the filter screen plate 6.3 and is subjected to gravity, the filter screen plate 6.3 will be slightly deformed, and this deformation is effectively buffered and absorbed by the spring 6.1, which can prevent the filter screen plate 6.3 from being permanently deformed or damaged due to long-term heavy pressure, thereby extending the service life of the filter assembly 6. At the same time, a through slot is provided on the top of the filter screen plate 6.3, and a filter screen 6.4 is fixedly connected to the inner cavity of the slot. When the material moves on the filter screen plate 6.3, smaller particles and impurities will pass through the filter screen 6.4 and fall into the collection area below, while larger particles will be retained on the filter screen plate 6.3, waiting for further processing or recycling.

[0046] In addition, since the filter screen plate 6.3 has a certain elasticity and buffering capacity, it can also reduce the impact and friction of the material during the filtering process to a certain extent, thereby reducing the wear rate of the filter screen and improving the filtering efficiency.

[0047] In one embodiment, the grinding assembly 4 includes a motor 4.1, a grinding roller 4.2, and a grinding plate 4.3. The motor 4.1 is fixedly connected to the side wall of the working box 1. The output end of the motor 4.1 passes through the side wall of the working box 1 and is fixedly connected to the grinding roller 4.2. The other end of the grinding roller 4.2 is rotatably connected to one side of the fixed plate 3. A plurality of grinding plates 4.3 are evenly fixedly connected to the side wall of the grinding roller 4.2. The two grinding rollers 4.2 rotate towards each other, and the grinding plates 4.3 on the two grinding rollers 4.2 are engaged with each other.

[0048] In a specific application of the embodiment of the present invention, the motor 4.1 is fixedly connected to the side wall of the working box 1, and the output end of the motor 4.1 passes through the side wall of the working box 1 and is fixedly connected to one end of the grinding roller 4.2. When the motor 4.1 is started, its rotational power will be directly transmitted to the grinding roller 4.2 to drive it to rotate. The other end of the grinding roller 4.2 is rotatably connected to one side of the fixed plate 3 to form a stable support structure to ensure that the grinding roller 4.2 can remain stable during the rotation process without shaking or offsetting. At the same time, the two grinding rollers 4.2 are designed to rotate in opposite directions, that is, their rotation directions are opposite. This design of rotating in opposite directions helps to enhance the grinding effect and improve the grinding efficiency.

[0049] On the side wall of the grinding roller 4.2, a number of grinding plates 4.3 are evenly fixedly connected to grind the aluminum ash waste into fine calcium aluminate powder. The grinding plates 4.3 on the two grinding rollers 4.2 are interlocked, which means that when they rotate, there will be close contact and friction between the grinding plates 4.3, thereby further improving the grinding effect.

[0050] During the grinding process, the aluminum ash waste is fed into the working box 1 and falls between the two grinding rollers 4.2 rotating in opposite directions. As the grinding rollers 4.2 rotate, the grinding plates 4.3 begin to squeeze and rub the aluminum ash waste. This continuous physical action gradually grinds the aluminum ash waste into a fine powdery substance, namely calcium aluminate powder. Finally, the ground calcium aluminate powder will be discharged through the discharge port at the bottom of the working box 1 for subsequent use.

[0051] In one embodiment, the stirring assembly 11 includes a motor three 11.1, a rotating shaft 11.2, and a stirring spiral blade 11.3. The motor three 11.1 is fixedly connected to the lower part of the side wall of the working box body 1. The output end of the motor three 11.1 passes through the side wall of the working box body 1 and is fixedly connected to the rotating shaft 11.2. One end of the rotating shaft 11.2 is rotatably connected to the side wall of the inner cavity of the working box body 1, and the stirring spiral blade 11.3 is fixedly sleeved on the rotating shaft 11.2.

[0052] In a specific application of the embodiment of the present invention, the motor 3 11.1 is fixedly connected to the lower part of the side wall of the working box 1. When the motor 3 11.1 is started, its output end will start to rotate and be fixedly connected to the rotating shaft 11.2 by a connection method that penetrates the side wall of the working box 1, thereby transmitting the rotational power to the rotating shaft 11.2. One end of the rotating shaft 11.2 is rotatably connected to the side wall of the inner cavity of the working box 1 to ensure its stability during the rotation process. At the same time, the rotating shaft 11.2 is fixedly sleeved with stirring spiral blades 11.3, and these spiral blades rotate together with the rotation of the rotating shaft 11.2.

[0053] The spiral shape of the stirring spiral blade 11.3 helps to generate a driving force during the rotation process, so that the material forms a circulation flow inside the working box 1. The circulation flow not only helps to fully mix the materials, but also promotes effective contact between the materials and the grinding medium, thereby improving the grinding efficiency. In addition, the material and size of the stirring spiral blade 11.3 are also carefully selected to ensure that it will not cause excessive wear or damage to the material during the stirring process.

[0054] In the specific operation process, after the aluminum ash waste is fed into the working box 1, the stirring component 11 starts to work, and the motor 3 11.1 drives the rotating shaft 11.2 and the stirring spiral blade 11.3 to rotate, so that the material forms a circulation flow under the promotion of the spiral blade, which not only helps to evenly mix the material, but also enables the material to be more fully ground and refined during the grinding process. At the same time, the operation of the stirring component 11 can also promote the heat exchange and chemical reaction between the material and the grinding medium, thereby accelerating the formation of calcium aluminate.

[0055] In one embodiment, the drying component 10 includes an exhaust pump 10.1, an air flow storage box 10.2, an exhaust main pipe 10.3, an exhaust branch pipe 10.4, a nozzle 10.5, and an exhaust hood 10.6. The exhaust pump 10.1 is fixedly connected to the bottom of the inner cavity of the installation box 9, and the output end of the exhaust pump 10.1 is fixedly connected to the air flow storage box 10.2 through a pipeline, one side of the air flow storage box 10.2 is fixedly connected to the exhaust main pipe 10.3, one end of the exhaust main pipe 10.3 is fixedly connected to the exhaust branch pipe 10.4, and one side of the exhaust branch pipe 10.4 is evenly fixedly connected with a plurality of nozzles 10.5, the input end of the exhaust pump 10.1 is fixedly connected to the exhaust hood 10.6 through a pipeline, and the exhaust hood 10.6 is fixedly connected to the side wall of the inner cavity of the installation box 9.

[0056] In a specific application of the embodiment of the present invention, the vacuum pump 10.1 is fixedly connected to the bottom of the inner cavity of the installation box 9. When the vacuum pump 10.1 is started, it extracts humid air or material gas containing moisture from the vacuum hood 10.6 through a pipeline. The vacuum hood 10.6 is fixedly connected to the inner cavity side wall of the installation box 9, and its position is designed to be able to efficiently capture the material gas without interfering with the grinding process. The extracted humid air or material gas is then sent to the airflow storage box 10.2. The main function of the airflow storage box 10.2 is to temporarily store these gases and pre-treat the gases, such as removing some moisture or heating to improve the drying efficiency.

[0057] The pretreated gas flows out from one side of the gas flow storage box 10.2 and is transported to each gas outlet branch pipe 10.4 through the gas outlet main pipe 10.3. The gas outlet branch pipes 10.4 are evenly distributed inside the device to ensure that the dry gas can evenly cover the material to be dried. On one side of each gas outlet branch pipe 10.4, a plurality of nozzles 10.5 are evenly and fixedly connected. The nozzles 10.5 enable the dry gas to be sprayed out in the form of fine airflow, fully contacting and exchanging with the material, thereby effectively removing moisture from the material.

[0058] In one embodiment, the main air outlet pipe 10.3 penetrates into the inner cavity of the working box body and is fixedly connected to an air outlet branch pipe 10.4, and several air outlet branch pipes 10.4 are interconnected and fixedly connected to the side wall of the inner cavity of the working box body, and several nozzles 10.5 are fixedly connected to the side wall of the air outlet branch pipe 10.4. A through vent hole 20 is opened on one side of the installation box 9, and a dustproof net is fixedly connected to the inner cavity of the vent hole 20, and an exhaust hood 10.6 is fixedly connected to one side of the vent hole 20.

[0059] In a specific application of the embodiment of the present invention, the dust and moisture generated during the grinding process are first captured by the exhaust hood 10.6. The exhaust hood 10.6 is fixedly connected to one side of the vent 20, and can efficiently guide and collect the dust and moisture in the grinding area to prevent them from escaping to the outside of the working environment. The vent 20 not only provides the necessary connection channel for the exhaust hood 10.6, but also effectively blocks impurities and dust in the external environment from entering the working box through the dustproof net fixedly connected to its inner cavity, thereby keeping the grinding environment clean.

[0060] The captured dust and moisture are then sent to the main air outlet pipe 10.3, which runs through the inner cavity of the working box and is fixedly connected to a plurality of air outlet branch pipes 10.4. These air outlet branch pipes 10.4 are interconnected and fixedly connected to the side walls of the inner cavity of the working box, ensuring that the dust and moisture generated during the grinding process can be quickly and evenly guided to the exhaust system to avoid local accumulation and escape.

[0061] On the side wall of each outlet branch pipe 10.4, a plurality of nozzles 10.5 are fixedly connected, and the function of these nozzles 10.5 is to further refine and disperse the captured dust and moisture so as to better connect and process with the subsequent processing system (such as dust collector, dryer, etc.). At the same time, the uniform distribution of the nozzles 10.5 also ensures the continuity and stability of the exhaust process, avoiding the dust accumulation or moisture retention caused by the local poor exhaust.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0063] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
