Description

Technical Field

[0001] This invention relates to the field of fine powder equipment technology, and in particular to an ultrafine powder classifier with an internal circulation dispersing function. Background Technology

[0002] Calcium hydroxide is characterized by its strong alkalinity, reactivity, and adsorption properties. It is widely used in industry, agriculture, and construction, and can be produced into calcium hydroxide powders of varying purity and particle size. Currently, most calcium hydroxide classifiers on the market are three-stage separation classifiers used in cement production. However, due to variations in the specific gravity, moisture content, binding properties, and particle structure of calcium hydroxide, classifiers often experience issues such as low output, equipment blockage, low powder selection efficiency, and the presence of many fine powders mixed with coarse powder in the slag. These problems cause numerous difficulties and challenges in production and operation, leading to a series of problems.

[0003] The existing refining equipment is mostly a single-processing structure. After refining the materials, they are sorted and discharged, requiring collection and processing again, which reduces production efficiency. Repeated refining processes increase the types of materials used in the equipment, leading to increased production costs. Summary of the Invention

[0004] This invention provides an ultrafine powder classifier with an internal circulation dispersing function. After the material is introduced into the device, it falls to the refining component for refining. The refined material then falls to the dispersing component for dispersion. Subsequently, the airflow entering from the bottom blows the finer particles, which rise and are discharged from the outer shell component. Heavier particles fall down, and airflow is introduced into the air inlet component of the device, causing the larger particles to rise again and re-enter the refining component from auxiliary components and other locations for cyclic refining.

[0005] This invention provides an ultrafine powder classifier with an internal circulation dispersing function, specifically comprising: a shell assembly; a refining component installed inside the bottom of the shell assembly; an auxiliary component installed at the outer end of the refining component at the bottom of the shell assembly; a guide component fixedly installed at the bottom of the auxiliary component; a dispersing component installed at the bottom of the guide component; the dispersing component being connected to the shell assembly; an air inlet component installed at the bottom of the guide component; and two sets of discharge components installed at the bottom of the air inlet component.

[0006] Furthermore, a discharge hood is installed at the top center of the outer shell plate of the outer shell assembly. The outer interface of the discharge hood is connected to the discharge pipe. A drive shaft is rotatably installed on the discharge hood. Power equipment can be installed on the outer ends of the discharge hood and the outer shell plate.

[0007] Furthermore, the refining box of the refining component is installed at the bottom position inside the outer shell assembly. A rotating platform is rotatably installed at the middle position of the refining box, and the rotating platform is fixed on the drive shaft of the outer shell assembly. The refining box is set as a stepped conical structure. A rotor frame is snapped onto the refining box. Vertical positioning strips are provided on the inner wall of the refining box. A stator frame is installed in the refining box at the position corresponding to the positioning strips. Both the stator frame and the rotor frame are provided with toothed plates, and the toothed plates of the stator frame and the positioning strips are interlaced.

[0008] Furthermore, the auxiliary cover of the auxiliary component is installed at the bottom of the outer shell assembly. The outer wall of the auxiliary cover is configured to be inclined towards the top. A guide ring is installed at the inner end of the auxiliary cover. A vertical plate is installed at the guide ring. The vertical plate of the guide ring is configured to be inclined in one direction.

[0009] Furthermore, the outer cover of the guide assembly is installed at the bottom of the auxiliary assembly. A reinforcing rib is provided on the outer wall of the lower end of the outer cover. A guide plate is rotatably installed on the inner wall of the upper end of the outer cover. The outer cover is arranged in a circumferential array. An external connecting rod is provided at the outer end of the guide plate of the outer cover. The bottom of the external connecting rod is spherical. A synchronizing rod is connected to the bottom of the external connecting rod. Adjacent synchronizing rods are connected to each other. The outer cover and the synchronizing rod are configured as a double-layer structure.

[0010] Furthermore, the outer end of the connecting rod of the dispersing component is connected to the bottom of the guide component, and the inner end of the connecting rod is mounted on the support. The support is connected to the drive shaft of the outer shell component. A dispersing disc is installed near the support on the drive shaft. A spring is provided at the bottom of the dispersing disc, and an inclined through groove is provided on the dispersing disc.

[0011] Furthermore, the bottom cover box of the air intake assembly is installed at the bottom of the guide assembly. The bottom cover box is funnel-shaped, and an air intake box is installed on the outer wall in the middle of the bottom cover box. An external connecting cylinder is provided on the air intake box. A guide frame is provided at the contact position between the air intake box and the bottom cover box, and the guide frame is arranged in an inclined manner.

[0012] Furthermore, the discharge cylinder of the discharge assembly is installed at the bottom of the air intake assembly. The discharge cylinder is configured as two sets of structures, one above the other. A baffle plate is hinged to the upper end of the discharge cylinder. The outer end of the baffle plate is connected to the transmission frame. The end of the transmission frame is connected to the control frame. The control frame is configured as an arc-shaped structure. A ball-shaped rod is provided on the outer end face of the control frame.

[0013] This invention provides an ultrafine powder classifier with an internal circulation dispersing function, which has the following beneficial effects: In this invention, the bottom of the drive shaft of the outer casing assembly contacts the dispersing component, making the drive shaft more stable and allowing the drive shaft to connect to the power component from the top. A refining component is also installed on the drive shaft. When material enters the refining component, it follows the drive shaft to refine the material. The bottom of the refining component discharges the refined material, which falls onto the dispersing disc of the dispersing component. The rotating disc disperses the material, and airflow is introduced from the bottom of the device, passing through the material dispersed by the dispersing disc, thus achieving a finer particle size distribution. The material is discharged from the discharge hood of the outer casing assembly, while the heavier coarse particles will descend. The descending coarse particles will approach the air intake assembly and be guided by airflow, causing the coarse particles to rise to a position close to the refining assembly. The relatively heavier particles will fall into the refining assembly, and the finer particles will be discharged through the discharge hood. This allows the refining assembly to further refine the coarse particles, thus completing the material recycling and refining process. The guide assembly installed on the equipment can assist in guiding the airflow blown out by the air intake assembly, and the structure of the discharge assembly can discharge the waste material at the bottom.

[0014] In addition, the refining box is directly fixed at the lower end of the outer casing assembly, while the rotating platform is fixed to the drive shaft. When the drive shaft rotates, the material entering the refining box will drive the rotating platform to rotate. As the rotating platform rotates with the drive shaft, the stator frame will be fixed on the refining component. At this time, the material in the refining box will be crushed by the toothed plates of the stator frame and the positioning strip, so that the refining component can achieve the refining effect on the material. The toothed plates are set to be arranged in an alternating manner, so that the refining component can refine the material more efficiently.

[0015] In addition, an auxiliary cover is installed at the bottom of the outer casing assembly, and the outer wall of the auxiliary cover is set to be inclined towards the top. When the airflow is received at the auxiliary cover, it can be gathered towards the top and then towards the middle through the inclined structure of the auxiliary cover. The guide ring is installed at the inner end of the auxiliary cover, and the inclined plate of the guide ring guides the airflow. After the material carried by the airflow is gathered at the top, the heavier particles will fall to the refining component for further processing, while the lighter refined particles will be discharged from the outer casing assembly.

[0016] Furthermore, a dispersion component can be installed at the bottom of the outer casing, thereby reinforcing the outer wall of the bottom of the outer casing and further increasing the overall strength of the device. This facilitates the installation of the dispersion component at the bottom of the outer casing, which is used to disperse materials. The materials will rise from the guide component, allowing the guide plate to be rotated and installed at the inner end of the outer casing. An external rod is set at the outer end of the guide plate, allowing direct control of the guide plate by directly controlling the external rod. The guide plate assists in guiding the airflow. The guide plate is arranged in a circumferential array, which further enhances the airflow guidance. The bottom of the external rod is spherical, allowing it to connect to a synchronizing rod. This enables the synchronizing rod to swing and control the external rod at any angle. Adjacent synchronizing rods are interconnected, allowing the synchronizing rod to synchronously control multiple sets of external rods, thus achieving synchronous control of the guide plate.

[0017] Furthermore, the bottom position of the drive shaft is more stable. A bearing seat is directly installed at the bottom of the drive shaft, and a connecting rod is connected to the outer end of the bearing seat. The bearing seat is fixed to the bottom of the guide assembly through the connecting rod, which makes the bottom of the drive shaft more stable. The dispersing disc can catch the falling material. At this time, the dispersing disc rotates with the drive shaft, and the dispersing disc can disperse the caught material by rotating, thereby better dispersing and separating the material. The dispersing disc is equipped with springs and inclined through grooves, which ensures that the dispersing disc can stably disperse the material.

[0018] In addition, the air intake assembly is set as the main bottom airflow structure. The air intake box is directly installed in the middle of the bottom cover box. The external cylinder set at the outer end of the air intake box can be connected to the external pipeline for air supply. At this time, a guide frame is set inside the air intake box to realize the inclined guide frame, which has the function of guiding the airflow, allowing the airflow to better blow the material, and facilitating the material discharge separation and circulation effect of the airflow.

[0019] In addition, after the device is used, some waste and debris will remain at the bottom of the equipment. In order to discharge the debris at the bottom of the air intake component, a discharge cylinder is directly installed at the bottom of the air intake component. The baffle plate installed on the discharge cylinder can be opened better. When the baffle plate is opened, the baffle plate will fluctuate the accumulated debris, allowing the debris to be discharged quickly. A control frame is installed on the transmission frame at the outer end of the baffle plate, which enables the control frame to quickly control the baffle plate. The ball rod of the control frame makes it more convenient to control the baffle plate. Attached Figure Description

[0031] Among them, such as Figure 4 Figure 9As shown, the discharge cylinder 701 of the discharge assembly 7 is installed at the bottom of the air intake assembly 6.

The control frame 704 is configured with an arc-shaped structure. A ball-shaped rod is provided on the outer end face of the control frame 704. After the device is used, some waste and debris will remain at the bottom of the equipment. To prevent the waste from entering the air intake assembly 6, the discharge cylinder 701 is designed to be installed at the bottom of the air intake assembly 6. The bottom debris is discharged by directly installing the discharge cylinder 701 at the bottom of the air intake assembly 6. The baffle 702, which is hinged to the discharge cylinder 701, can be opened more easily.

The ball rod of the control frame 704 makes it easier to control the baffle 702.

[0032] The working principle of this invention is as follows: First, the two sets of discharge components 7 at the bottom of the equipment need to be manually closed. Then, the dispersion component 5 is adjusted to ensure that the transmission shaft 103 at the outer shell component 1 limited by the dispersion component 5 is stable. According to the airflow requirements of the air intake component 6, the guide component 4 is oscillated to ensure that the airflow of the air intake component 6 is guided by the guide component 4. At the same time, it is necessary to observe whether the external connection between the discharge hood 102 and the air intake component 6 is stable, and observe whether other external interfaces on the outer wall of the equipment are stable. During operation, material enters the refining component 2 from the top. The refining component 2 is mounted on the drive shaft 103 of the outer casing 1, causing the outer casing 1 to rotate and rapidly refine the incoming material. The refined material then falls from the bottom of the refining component 2 onto the dispersing disc 503, which also rotates with the drive shaft 103. The dispersing disc 503 disperses the received material, and the airflow passing through this area carries the lighter particles upwards, thus refining the material particles from... The drive shaft 103 guides the larger particles that fall further down, allowing them to directly contact the airflow entering through the air intake assembly 6. This airflow lifts the material, and as the material passes through the guide assembly 4, it rotates in a guided manner. Some of the lighter, finer particles are discharged through the discharge hood 102, while the heavier particles fall back into the refining assembly 2 for further processing. This process creates a cyclical refining effect on the material, further increasing work efficiency. The discharge assembly 7 at the bottom of the device facilitates the discharge of waste materials.
