Description

Technical Field

[0001] This invention relates to the field of zirconium oxide manufacturing technology, and in particular to a zirconium oxide sintering and crushing device. Background Technology

[0002] Zirconia manufacturing technology is a complete technical system surrounding the production of zirconia materials, encompassing core processes such as raw material processing, synthesis, molding, firing, and finishing. It uses zircon sand and other materials as initial raw materials, purifying them chemically to prepare zirconia powder. This powder is then combined with molding processes to form a green body, which is subsequently fired at high temperatures to create zirconia products with high strength and high-temperature resistance. These products are widely used in ceramics, electronics, and medical fields. The core technology lies in controlling material purity, microstructure, and final properties to adapt to the needs of different application scenarios.

[0003] A zirconia sintering and crushing device is a specialized piece of equipment in the "post-sintering processing" stage of zirconia manufacturing technology. Its core function is to crush and process sintered zirconia materials. It can crush lumpy or agglomerated zirconia that may form after sintering into uniform particle sizes that meet the requirements of subsequent shaping, grinding, or finishing through mechanical crushing structures (such as jaw crushers and impact crushers). The design of this device must be adapted to the high hardness and brittleness of sintered zirconia, avoiding the introduction of impurities or over-crushing during the crushing process. It is a key piece of equipment to ensure the accuracy and quality of subsequent zirconia processing.

[0004] However, in the existing technology, some zirconia crushing devices rely on manual feeding of materials into the crushing equipment. In this mode, the manual operation is easily affected by fatigue, attention and experience differences, resulting in unstable feeding amount. Too much material can easily cause the equipment to overload and jam, while too little material will cause the equipment to be idle, wasting energy and performance. At the same time, it requires continuous investment of labor costs, and it is difficult to ensure that the batch material quantity is consistent, which leads to uneven zirconia particle size after crushing, which cannot meet the requirements of high-precision production.

[0005] Therefore, a zirconium oxide sintering and crushing device is proposed to address the above problems. Summary of the Invention

[0006] To overcome the above shortcomings, the present invention provides a zirconia sintering and crushing device, which aims to improve the problem that some existing zirconia crushing devices rely on manual feeding of materials into the crushing equipment. In this mode, manual operation is prone to errors in the amount of materials fed due to fatigue or differences in experience, which increases labor costs and cannot ensure the stability of the amount of materials in each batch, thus reducing the uniformity of zirconia crushing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A zirconia sintering and crushing device includes a machine body, a jaw crusher fixedly connected to the top of the machine body, a material bucket fixedly connected to the top of the machine body, an inlet and outlet assembly fixedly connected to the outside of the material bucket, a funnel plate fixedly connected to the inner wall of the material bucket, a funnel sleeve provided at the bottom of the funnel plate, a conical plate slidably provided on the inner wall of the funnel sleeve, a sliding column fixedly connected to the bottom of the conical plate, a spring sleeved on the outside of the sliding column, a support plate slidably connected to the outside of the sliding column, two support rods sliding on the inner wall of the material bucket fixedly connected to the front and rear sides of the support plate, an adjustment assembly provided at the outer end of the plurality of support rods, a base fixedly connected to the bottom of the inner wall of the material bucket, an inclined guide plate rotatably connected to the top of the base, and a discharge pipe fixedly provided at the rear side of the jaw crusher. As a further description of the above technical solution: The feeding and discharging assembly includes a feeding conveyor fixed to the top left side of the material hopper, a discharging conveyor fixedly connected to the bottom right side of the material hopper, and the other end of the discharging conveyor fixed to the feeding port of the jaw crusher. As a further description of the above technical solution: A limiting plate is fixedly connected to the bottom of the sliding column, and the limiting plate is externally fixedly connected to one side of multiple support rods. As a further description of the above technical solution: The adjusting assembly includes a pressure ring that slides outside the material barrel. Two pressure plates are provided on the outside of the pressure ring. Two trigger posts that slide on the inner wall of the pressure ring are fixedly connected to the inner side of the pressure plates. A spring is sleeved on the outside of each trigger post. A push block that slides on the inner wall of a support rod is fixedly connected to one end of each trigger post. Limit blocks are fixedly connected to both sides of the push block. A triangular plate is slidably connected to the outside of the limit block, and the outside of the triangular plate slides on the inner wall of the support rod. An insert plate is fixedly connected to the outside of the triangular plate. Multiple slots that fit and engage with the insert plates are provided on the inner wall of the material barrel. As a further description of the above technical solution: One end of the first spring is fixed to the bottom of the conical plate, and the other end of the first spring is fixed to the top of the support plate. One end of the second spring is fixed to the outside of the trigger post, and the other end of the second spring is fixed to one side of the inner wall of the pressure ring. As a further description of the above technical solution: Both the upper and lower sides of the support rod are fixedly connected to baffles, and the outer side of the baffles slides against the inner wall of the material barrel. As a further description of the above technical solution: The top of the inner wall of the material barrel is eccentrically connected to a turntable, and a rotating wheel is fixedly connected to the left side of the turntable. Another rotating wheel is rotatably connected to the inner wall of the material barrel. Pull ropes are sleeved on the outside of the two rotating wheels, and a striking hammer that contacts the inclined guide plate is fixedly connected to the right side of one of the rotating wheels. As a further description of the above technical solution: The inner wall of the funnel sleeve is fixedly connected with multiple sealing gaskets, and the sealing gaskets are in close contact with the bottom of the funnel plate.

[0008] The present invention has the following beneficial effects: 1. In this invention, a quantitative triggering structure composed of a conical plate and a spring, combined with the guiding effect of the sliding column and the supporting positioning of the support plate, realizes automatic batch quantitative feeding of zirconia, replacing the traditional manual feeding mode. This design avoids the inconsistent feeding amount caused by fatigue from long-term operation and differences in experience among different personnel, and significantly reduces labor input costs. At the same time, it controls the material quantity of each batch to be stable and consistent, significantly improving the particle size uniformity of zirconia after crushing.

[0009] 2. In this invention, the single-batch conveying volume can be flexibly adjusted using an adjustment assembly consisting of a pressure ring, a pressure plate, and a trigger post. Specifically, pressing the pressure plate causes the trigger post to compress the second spring, releasing the locking limit between the insert plate and the insertion port. Then, pulling the pressure ring causes the support rod to slide up and down along the inner wall of the material barrel, thereby changing the height of the support plate and adjusting the initial tension of the first spring. This adjustment allows the trigger threshold of the conical plate to adapt to different batches and different processing requirements of material volume, effectively enhancing the adaptability of the device to diverse production scenarios and reducing the frequency of equipment replacement.

[0010] 3. In this invention, a linkage structure consisting of an eccentrically rotating turntable inside the material hopper, paired rotating wheels, a transmission rope, and a striking hammer is utilized. During the continuous feeding process of the feeding conveyor, the turntable is driven to rotate by the gravity of the zirconia, and the rotating wheels and the transmission rope drive the striking hammer to periodically strike the guide plate. This linkage action drives the guide plate to continuously oscillate, which effectively prevents the calcined zirconia from adhering to the surface of the guide plate due to residual stickiness at high temperatures or electrostatic adsorption between materials, thus avoiding blockage of the conveying channel. This ensures that the material conveying channel is always unobstructed, thereby improving the continuity and efficiency of the overall production process. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Reference Figures 1 to 8 This invention provides an embodiment of a zirconia sintering and crushing device, comprising a body 1, which provides a fixed support foundation for the entire device and allows for the opening and closing of a jaw crusher 2; the jaw crusher 2 is fixedly connected to the top of the body 1, and is used to crush the conveyed zirconia; a material bucket 3 is also fixedly connected to the top of the body 1, which is used to temporarily store the sintered zirconia and provide a carrying space for subsequent conveying; an infeed and discharge assembly is fixedly connected to the outside of the material bucket 3, which is used to input zirconia and convey it to the jaw crusher 2; the infeed and discharge assembly includes a feeding conveyor 4 fixed to the top left side of the material bucket 3, which is used to convey the sintered zirconia from the outside into the material bucket 3; and a discharge conveyor 5 is fixedly connected to the bottom right side of the material bucket 3, which is used to convey a quantitative amount of zirconia discharged from the material bucket 3 to the jaw crusher 2.

[0015] The other end of the discharge conveyor 5 is fixed to the feed port of the jaw crusher 2. The metered zirconium oxide is transported to the jaw crusher 2 through the pipe on the right side of the discharge conveyor 5 for crushing. A funnel plate 6 is fixedly connected to the inner wall of the hopper 3. The funnel plate 6 guides the zirconium oxide to slide down to the top of the conical plate 8 via a slope. A funnel sleeve 7 is provided at the bottom of the funnel plate 6. The funnel sleeve 7 cooperates with the conical plate 8 to form an openable and closable channel to control the descent of the zirconium oxide. Multiple sealing gaskets are fixedly connected to the inner wall of the funnel sleeve 7. The sealing gaskets are used to ensure that the bottom of the funnel plate 6 is in close contact with the funnel sleeve 7, ensuring that there is no zirconium oxide leakage under normal conditions. The sealing gaskets are in close contact with the bottom of the funnel plate 6. A conical plate 8 is slidably provided on the inner wall of the funnel sleeve 7. The conical plate 8 controls the opening and closing of the gap between itself and the funnel sleeve 7 by moving up and down, so as to realize the quantitative falling of zirconium oxide. A sliding column 9 is fixedly connected to the bottom of the conical plate 8. The sliding column 9 provides guidance for the up and down movement of the conical plate 8, and can also transmit the zirconium oxide pressure on the conical plate 8.

[0016] A limiting plate 10 is fixedly connected to the bottom of the sliding column 9. The limiting plate 10 is used to limit the sliding range of the sliding column 9 and prevent the sliding column 9 from detaching from the support plate 12. A spring 11 is sleeved on the outside of the sliding column 9. The spring 11 supports the conical plate 8 through elastic force. When the weight of the material overcomes the elastic force, it pushes the conical plate 8 downward. After the material is unloaded, it drives the conical plate 8 to reset, realizing quantitative conveying. One end of the spring 11 is fixed to the bottom of the conical plate 8, and the other end of the spring 11 is fixed to the top of the support plate 12. The support plate 12 is slidably connected to the outside of the sliding column 9. The sliding column 9 is provided with sliding support, and the support rod 13 is connected to fix its own position. Two support rods 13 that slide on the inner wall of the material barrel 3 are fixedly connected to the front and rear sides of the support plate 12. The support rods 13 are used to support the support plate 12 and can slide up and down to adjust the height of the support plate 12. The limit plate 10 is fixedly connected to the outside of the multiple support rods 13 on the same side. The outer ends of the multiple support rods 13 are provided with adjustment components. The adjustment components are used to adjust the height of the support rods 13, thereby changing the initial tension of the spring 11 and realizing the adjustment of the single conveying volume.

[0017] The adjustment assembly includes a pressure ring 14 that slides outside the material barrel 3. The pressure ring 14 is used to drive the support rod 13 to slide up and down, providing an operating component for adjusting the height of the support rod 13. Two pressure plates 15 are provided on the outside of the pressure ring 14. The pressure plates 15 are used to drive the trigger pins 16 to slide by pressing, thus initiating the adjustment operation. Two trigger pins 16 that slide on the inner wall of the pressure ring 14 are fixedly connected to the inner side of the pressure plates 15. The trigger pins 16 are used to transmit the pressing force of the pressure plates 15 and push the push block 19 to move. The trigger pins 16 are sleeved on the outside. There is a second spring 17, which is used to shrink and store elastic force when the pressure plate 15 is pressed. After the pressure plate 15 is released, the elastic force drives the trigger post 16 to reset, realizing the automatic engagement of the insert plate 22 and the socket 23. One end of the second spring 17 is fixed to the outside of the trigger post 16, and the other end of the second spring 17 is fixed to one side of the inner wall of the pressure ring 14. Baffles 18 are fixedly connected to both the upper and lower sides of the support rod 13. The baffles 18 are used to prevent zirconium oxide from leaking out from the gap between the support rod 13 and the inner wall of the material barrel 3, thus avoiding material waste.

[0018] The outer side of the baffle 18 slides against the inner wall of the material barrel 3. One end of the trigger post 16 is fixedly connected to a push block 19 that slides against the inner wall of the support rod 13. The push block 19 is used to transmit the thrust of the trigger post 16, driving the limit block 20 to move. Limit blocks 20 are fixedly connected to both sides of the push block 19. The limit blocks 20 are used to drive the triangular plate 21 to slide along the inner wall of the support rod 13, controlling the extension and retraction of the insert plate 22. The outer side of the limit block 20 is slidably connected to the triangular plate 21. The triangular plate 21 is used to drive the insert plate 22 to move. The insert plate 22 can be engaged or disengaged from the socket 23; and the outside of the triangular plate 21 slides on the inner wall of the support rod 13. The outside of the triangular plate 21 is fixedly connected to the insert plate 22. The insert plate 22 can fix or release the support rod 13 by engaging or disengaging with the socket 23, thereby adjusting the height of the support rod 13. The inner wall of the material bucket 3 is provided with multiple sockets 23 that are adapted to engage with the insert plate 22. The sockets 23 provide multiple engagement positions for the insert plate 22. The height of the support rod 13 can be adjusted in stages by engaging at different positions.

[0019] A turntable 24 is eccentrically connected to the top of the inner wall of the material hopper 3. The turntable 24 rotates due to the gravity of the zirconium oxide and continuous feeding, simultaneously dispersing the zirconium oxide and preventing material accumulation. A wheel 25 is fixedly connected to the left side of the turntable 24, which transmits the rotational power of the turntable 24 and drives another wheel 25 to rotate via a pull rope 26. Another wheel 25 is rotatably connected to the inner wall of the material hopper 3. The two wheels 25 work together to transmit power via a pull rope 26, driving the striking hammer 27 to rotate. An external pull rope 26 is provided, which is used to connect two rotating wheels 25 to transmit rotational power, so that the striking hammer 27 can obtain rotational power; a base 28 is fixedly connected to the bottom of the inner wall of the material barrel 3, which provides rotational support for the inclined guide plate 29, so that the inclined guide plate 29 can be turbulent; the top of the base 28 is rotatably connected to the inclined guide plate 29, which guides the zirconia to slide towards the discharge conveyor 5 by the inclined angle, and at the same time turbulent under the action of the striking hammer 27 to prevent the zirconia from adhering and blocking the material.

[0020] One of the impellers 25 has a hammer 27 fixedly connected to the right side, which contacts the inclined guide plate 29. The hammer 27 strikes the inclined guide plate 29 periodically, causing the inclined guide plate 29 to bounce like a seesaw, thus preventing zirconium oxide from adhering. A discharge pipe 30 is fixedly installed on the rear side of the jaw crusher 2. The discharge pipe 30 is used to output the zirconium oxide crushed by the jaw crusher 2, thus completing the crushing process.

[0021] Working principle: First, the calcined zirconia is conveyed to the hopper 3 by the feed conveyor 4 in the feeding assembly, and falls onto the eccentrically connected turntable 24. The gravity of the zirconia and the continuous feeding drive the turntable 24 to rotate. Through the transmission of the roller 25 and the pull rope 26, the striking hammer 27 periodically strikes the inclined guide plate 29. Since the inclined guide plate 29 is rotatably connected to the base 28, it will bounce like a seesaw, preventing the zirconia from adhering to the surface due to stickiness or static electricity that may exist after high-temperature firing, thus preventing material blockage.

[0022] Subsequently, after being dispersed by the turntable 24, the zirconium oxide slides down the slope of the funnel plate 6 to the top of the conical plate 8. As the material accumulates, its weight gradually overcomes the elastic force of the spring 11, pushing the conical plate 8 downwards. The sliding column 9 slides along the support plate 12, creating a gap between the conical plate 8 and the funnel sleeve 7. Here, the funnel sleeve 7 and the bottom of the funnel plate 6 are in tight contact through a sealing gasket, ensuring no leakage under normal conditions. The zirconium oxide falls through the gap into the inclined guide plate 29 and slides along its inclined angle towards the discharge conveyor 5, where it is conveyed to the jaw crusher 2 for crushing, and finally output through the discharge pipe 30. During this process, the elastic restoring effect of the spring 11 ensures that after the material is unloaded or a certain weight of zirconium oxide is removed, the conical plate 8 rises to close the gap, achieving quantitative control of "one batch, one conveyor" and avoiding the unevenness problem of manual feeding.

[0023] To adjust the single-batch conveying volume, the adjustment component can be operated: Pressing the pressure plate 15 triggers the spring 17 to compress the trigger post 16 and pushes the push block 19, causing the limit block 20 to retract the triangular plate 21, and the insert plate 22 to disengage from the insertion port 23 on the inner wall of the material barrel 3. At this time, pulling the pressure ring 14 causes the support rod 13 to slide up and down. The baffle 18 here prevents material from leaking out from the gap between the support rod 13 and the material barrel 3. After the insert plate 22 is inserted into the corresponding height of the insertion port 23, release the pressure plate 15, and the spring 17 returns to its fixed position. The change in the position of the support rod 13 will change the height of the support plate 12, thereby adjusting the initial tension of the spring 11, realizing the adjustment of the trigger threshold of the conical plate 8, and adapting to the material volume requirements of different batches.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
