Description

Technical Field

[0001] This application relates to the field of material screening technology, specifically to a raw material screening device for an integral aluminum-zirconium-carbon sprue. Background Technology

[0002] When preparing raw materials for the production of monolithic aluminum zirconium carbon (AZC) nozzles, the screening process is primarily aimed at removing large particles, foreign matter, and particles that do not meet the particle size requirements to ensure the homogeneity and quality of the final mixture. Traditional screening equipment typically only has a single screening function and cannot effectively handle the screening challenges of wet or highly viscous materials. This often leads to problems such as screen clogging, low screening efficiency, and material agglomeration, severely impacting production continuity and product quality.

[0003] For applications requiring fine grading, traditional vibrating screens are often used. The vibration makes it less likely for materials to clog the screen holes, and they are commonly used for primary screening. Secondary screening is usually used for more precise classification of materials. The screening accuracy of vibrating screens may not meet the requirements for high precision, especially in scenarios where fine particles are being processed or where strict control of particle size distribution is required.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0022] Please see Figure 1-6 This application provides a technical solution: a raw material screening device for an integral aluminum-zirconium-carbon sprue, including a hopper 1, an exciter 2 disposed on the outside of the hopper 1, a primary screening component 7 disposed on the inside of the hopper 1 and correspondingly disposed in a groove on the inner wall of the hopper 1, and connected by fasteners.

[0023] The hopper 1 is a container-shaped structure used to hold the raw materials to be screened; the outer wall is connected to the vibrator 2, which is usually an eccentric motor or an electromagnetic vibration device, to provide high-frequency vibration power, so that the hopper 1 generates regular vibration, promotes the uniform distribution of materials during the screening process and accelerates the passage of materials through the screen, prevents materials from clogging the screen holes, and improves screening efficiency and permeability.

[0024] The primary screening component 7 is set inside the hopper 1 and embedded in the inner wall groove. It has a screen structure with a specific aperture to achieve the preliminary screening function, separating coarse particles from fine particles in the raw material. By reasonably designing the size and distribution density of the screen holes, the screening accuracy is controlled.

[0025] The grooved structure on the inner wall provides a positioning and fixing base for the primary screening component 7, enhancing screening stability. The grooved embedding structure ensures that the screening component is stable and does not shift, preventing it from falling off or deforming due to vibration. At the same time, the use of fasteners allows for quick disassembly, facilitating the rapid replacement of screens with different aperture sizes to meet the screening requirements of different materials.

[0026] The hopper 1 adopts a cavity structure, and a heating wire assembly 3 is installed inside the cavity structure.

[0027] The hopper 1 has a hollow structure, which provides installation space for the heating wire assembly 3, avoids direct exposure to the material, and extends its service life; the inner plate is made of a fast heat-conducting material to enhance heat transfer efficiency.

[0028] The heating wire assembly 3 is embedded in the cavity structure of the hopper 1. It is usually composed of multiple heating wires arranged in a spiral or serpentine pattern. It is connected to an external power source through wires to pre-dry the raw materials entering the hopper 1, reduce the moisture content of the raw materials, and improve the efficiency of subsequent screening. It also prevents the wet materials from sticking or clumping during the screening process, ensuring a smooth screening process. The heating wires are evenly distributed around the circumference, making the heat distribution more even and improving the uniformity of drying.

[0029] The lower end of the hopper 1 is provided with a guide groove, and a secondary screening component is provided in the guide groove. The secondary screening component includes a receiving component 4, a sliding block 5 located outside the receiving component 4, a connecting shaft 6, and a rotary drive assembly for driving the receiving component 4 to vibrate up and down. The receiving component 4 is located below the primary screening component 7, and the outer diameter of the receiving component 4 is smaller than the inner diameter of the hopper 1. The sliding block 5 is provided in the guide groove of the hopper 1, and the lower end of the sliding block 5 is provided with a connecting shaft 6. The connecting shaft 6 is correspondingly provided with an annular groove on the rotary drive assembly.

[0030] The guide groove is located at the lower end of the hopper 1 and is evenly distributed around the circumference of the hopper 1. It provides a guiding function to ensure that the sliding block 5 and its connecting components can move smoothly along the predetermined path; it prevents the sliding block 5 from shifting or deviating laterally and keeps the receiving part 4 in the correct position for screening.

[0031] The receiving component 4 is located below the primary screening component 7. Its outer diameter is smaller than the inner diameter of the hopper 1. Its inner side has a screen with a specific aperture. The screen has a circular structure and is installed at the circular step at the lower end of the receiving component 4. It is installed with fasteners and is easy to disassemble and replace. It is used to receive the material falling from the primary screening component 7 and perform secondary fine screening. The receiving component 4 achieves efficient screening by vibrating up and down to ensure that the material is fully dispersed and passes through the screen holes.

[0032] The lower end of the connecting shaft 6 is provided with a guide slider, which cooperates with the annular groove on the rotary drive group to transmit the power generated by the rotary drive group to the sliding block 5, thereby driving the receiving part 4 to vibrate up and down.

[0033] The design of the guide slider and the annular groove allows the connecting shaft 6 to move flexibly within a certain range, ensuring a smooth and controllable vibration process, enhancing the stability of the entire transmission, and reducing wear and noise.

[0034] Furthermore, a support base 8 is provided below the hopper 1, and an intermediate guide 9 is provided at the lower end of the support base 8. A receiving bucket 10 is correspondingly provided on the intermediate guide 9.

[0035] The support base 8 is located below the hopper 1, providing a stable support foundation to ensure that the entire screening device will not tilt or shake during operation.

[0036] The intermediate guide 9 is located on the lower surface of the support base 8. It corresponds to the discharge port of the secondary screening component and is the material transfer path between the secondary screening component and the receiving bucket 10, ensuring that the material after secondary screening can flow smoothly into the receiving bucket 10.

[0037] The receiving hopper 10 is placed below the intermediate guide 9 to collect the finished material after final screening. The bottom of the receiving hopper 10 can also be equipped with pulleys for easy handling and cleaning.

[0038] Furthermore, a rotatable annular seat 11 is provided on the outer side of the intermediate guide component 9, and a groove is provided in the annular seat 11, which corresponds to the guide slider provided at the lower end of the connecting shaft 6.

[0039] More specifically, the slide rail inside the annular seat 11 is undulating, and the height difference of the undulation is 3cm.

[0040] The annular seat 11 is mounted on the outside of the intermediate guide member 9 and can rotate around its central axis. It has internal grooves for engaging with the guide slider.

[0041] The groove is set inside the annular seat 11 and is usually an undulating structure with a certain height difference. Different vibration modes can be achieved by changing the shape of the groove, thereby enhancing the screening effect. The guide slider at the lower end of the connecting shaft 6 is guided to move along a specific path to form a complex vibration trajectory. The existence of the height difference causes the receiving part 4 to produce a changing amplitude during vibration, which helps to improve screening efficiency and quality.

[0042] The guide slider is fixed at the lower end of the connecting shaft 6 and corresponds to the groove in the annular seat 11. It converts the rotation of the annular seat 11 into the up and down movement of the connecting shaft 6, ensuring that the connecting shaft 6 can run smoothly along the preset trajectory and avoid jamming caused by excessive friction.

[0043] Furthermore, a driven gear 12 is provided on the outer side of the annular seat 11, and the driven gear 12 meshes with a rotary drive assembly provided on the support seat 8.

[0044] The external driven gear 12 enables the ring seat 11 to obtain a power source through mechanical transmission, thereby achieving precisely controlled rotational motion.

[0045] Driven gear 12 receives power input from the rotary drive unit and transmits rotational torque to the annular seat 11; ensuring that the annular seat 11 can rotate smoothly at a predetermined speed and direction, thereby adjusting the material flow path or changing the screening mode.

[0046] Furthermore, a hopper cover plate 13 is provided on the upper surface of the hopper 1, and a thermometer is provided on the lower surface of the hopper cover plate 13.

[0047] Furthermore, a funnel-shaped guide 14 is provided below the primary screening component 7, the outlet of the guide 14 is located above the receiving component 4 in the secondary screening component, and the surface of the guide 14 is provided with an anti-sticking coating.

[0048] The guide component 14 is located below the primary screening component 7 and has a funnel-shaped design. Its discharge port is directly aligned with the receiving component 4 in the secondary screening component, smoothly guiding the material after primary screening into the secondary screening component for further screening. This ensures that the material falls accurately into the receiving component 4, preventing material from scattering or accumulating inside the equipment. The anti-stick coating reduces material adhesion, effectively improving the efficiency of the entire screening process and reducing downtime for cleaning.

[0049] Furthermore, a heat insulation layer is provided on the outer side of the hopper 1.

[0050] The heat insulation layer is wrapped around the outside of the hopper 1 and is made of high-efficiency heat insulation material, such as glass fiber, ceramic fiber or other high-temperature resistant heat insulation materials. It effectively prevents the heat generated by the heating wire assembly 3 from spreading outward, ensuring that more heat is concentrated inside the hopper 1, improving energy utilization efficiency, preventing the outer wall temperature of the hopper 1 from being too high, avoiding the risk of burns to operators, and reducing the impact of high temperature on external equipment or structures.

[0051] During use: Connect the heating wire assembly 3 to the power supply and confirm that the temperature control system is working properly. Confirm that the driven gear 12 on the outside of the ring seat 11 is properly engaged with the rotary drive assembly. Set a suitable heating temperature according to the particle size, moisture content, and other characteristics of the raw material to be screened, generally between 50 and 120°C. Adjust the vibration frequency of the vibrator 2 to adapt to different screening requirements. Set the rotation speed of the rotary drive assembly and start the heating wire assembly 3 to preheat the inside of the hopper 1. Monitor the temperature inside the hopper 1 in real time with a thermometer. When the set value is reached, proceed to the next step: open the hopper cover 13 and pour the raw material to be screened evenly into the hopper 1. Close the hopper cover. Plate 13 prevents dust from escaping or material from splashing. The vibrator 2 is turned on, causing the hopper 1 to vibrate at high frequency, which promotes the rapid flow of raw materials and begins preliminary screening. The raw materials are coarsely screened through the primary screening component 7. Large particles are intercepted and discharged, while fine particles fall into the guide component 14. The guide component 14 guides the material into the receiving component 4 of the secondary screening component. The anti-adhesion coating prevents material from adhering and clogging. The receiving component 4 vibrates up and down under the drive of the drive group to achieve fine screening. The connecting shaft 6 cooperates with the groove of the annular seat 11 through the guide slider to form a complex vibration path, which improves the screening accuracy. The qualified material after screening flows into the receiving bucket 10 through the intermediate guide component 9.
