Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and more specifically, particularly relates to a filtering device for aluminum silicon carbide carbon brick mixture. Background Art

[0002] In the production process of aluminum silicon carbide carbon bricks, the purity and uniformity of the mixture play a decisive role in the quality of the finished product, directly affecting its refractory performance and mechanical strength. If there are impurity particles or uneven composition distribution in the mixture, it is easy to cause local spalling and cracking of the brick body during use, greatly shortening the service life. And when using a filtering device during the mixing process, it can effectively remove large particle impurities, agglomerated materials and foreign matters in the mixture, ensuring the density and stability of the brick body structure. However, when the traditional filtering device is in use, it often relies on the mixture to pass through the filter screen under the action of gravity, resulting in a reduced passing efficiency of the mixture, and serious blockage on the surface of the filter screen due to continuous accumulation of the mixture, requiring shutdown for cleaning, thus reducing the production efficiency.

[0042] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0043] Example: Figures 1 to 12 As shown, the utility model provides an aluminum silicon carbide carbon brick mixture filtering device, including a support frame 11. The support frame 11 serves as a basic bearing component to provide stable support for the entire filtering device, bear the weight of multiple groups of filter components and the mixture, ensure that the device remains stable during operation, and prevent the filtering effect from being affected by shaking. Multiple groups of filter components are distributed on the support frame 11, and each group of filter components is centered on the filter tank 21. The feed hopper 22 at the top of the filter tank 21 is used to receive the aluminum silicon carbide carbon brick mixture to be filtered. The mixture enters the filter tank 21 through the feed hopper 22, and the discharge hopper 23 at the bottom is responsible for discharging the filtered mixture. The feed hopper 22, the filter tank 21 and the discharge hopper 23 are interconnected to form a filter chamber. This space provides a place for the filtering process of the mixture.

[0044] The filter sleeve 31 and rotating sleeve 41 within the filter chamber are key to achieving efficient filtration. The filter screen 32 at the bottom of the filter sleeve 31 intercepts impurities and particles that do not meet the required particle size, allowing only qualified material to pass through, thereby providing preliminary screening of the material mixture. The filter screen 32 divides the filter chamber into a feed section and a discharge section. The feed section receives the material to be filtered, while the discharge section receives the qualified material after filtration.

[0045] The rotating sleeve 41 is located inside the feeding part and is rotatably connected to the filter tank 21. The multiple groups of baffles 42 and striking members arranged inside it play an important role. As the rotating sleeve 41 rotates, the baffles 42 can stir and push the mixed material, making the mixed material more evenly distributed in the feeding part and accelerating the flow rate of the mixed material towards the filter screen 32. The bottom of the striking members on the baffles 42 contacts the filter screen 32. When the rotating sleeve 41 rotates, the striking members will continuously strike the filter screen 32, preventing impurities from accumulating and blocking on the filter screen 32, ensuring the smoothness of the filter screen 32 and allowing the mixed material to pass through smoothly.

[0046] The feeding box 12 above the support frame 11 can store a large amount of mixed material to be filtered and is respectively connected to the feeding hoppers 22 in multiple groups of filtering components, continuously and stably supplying the mixed material to each filtering component. The discharging pipe below the filter tank 21 is connected to the discharging hoppers 23 in multiple groups of filtering components, centrally collecting and transporting the qualified filtered mixed material to the subsequent process, ensuring the continuity of the entire filtering process and effectively improving the filtering efficiency of the aluminum silicon carbide carbon brick mixed material.

[0047] As Figure 3 , Figure 9 , Figure 10 shown, the multiple groups of positioning blocks 24 inside the filter tank 21 and the positioning grooves 33 on the filter sleeve 31 form a stable assembly system. The positioning blocks 24 are fixed on the inner wall of the filter tank 21. When the filter sleeve 31 is installed, the positioning blocks 24 are inserted into the corresponding positioning grooves 33. This cooperation determines the position of the filter sleeve 31 inside the filter tank 21. During the filtering process of the aluminum silicon carbide carbon brick mixed material, the positioning blocks 24 and the positioning grooves 33 can prevent the filter sleeve 31 from shifting or shaking, ensuring that the filter screen 32 is always in the proper position and allowing the mixed material to pass through the filter evenly. When the filter screen 32 needs to be cleaned or replaced, simply separate the filter sleeve 31 from the positioning blocks 24, which simplifies the maintenance process and improves the efficiency of equipment maintenance.

[0048] The rotation of the rotating sleeve 41 is completed by the cooperation of multiple groups of electromagnets 25 on the circumferential side of the filter tank 21 and the magnetic attraction blocks 34 on one side of itself. The electromagnets 25 are distributed in different positions on the filter tank 21. After being energized, they generate a magnetic field to attract the magnetic attraction blocks 34. By controlling the on-off sequence and time of the electromagnets 25 in different positions, the direction and intensity of the magnetic field can be changed, thereby driving the rotating sleeve 41 to rotate in a set direction and speed. Before the start of filtering, the electromagnets 25 are energized to generate a magnetic field, attracting the magnetic attraction blocks 34 and driving the rotating sleeve 41 to start smoothly inside the filter tank 21; when it is necessary to stop the rotating sleeve 41, cut off the power supply of the electromagnets 25, the magnetic field disappears, and the rotating sleeve 41 stops accordingly. This driving method facilitates the operator to flexibly adjust the working state of the rotating sleeve 41 according to the filtering situation of the mixed material, ensuring the filtering effect while also providing convenience for equipment maintenance.

[0049] AsFigure 3 , Figure 6 , Figure 7 , Figure 10 , Figure 11 As shown in Figure 11 , the striking member is composed of a striking block 43 and a spring, and is installed between the connecting plates 44 on one side of the baffle 42. The striking block 43 can rotate between two groups of connecting plates 44, and the spring connects the striking block 43 and the baffle 42 to form an included angle α of 10° to 90°. When the rotating sleeve 41 drives the baffle 42 to rotate, the striking block 43 moves together with the baffle 42. When passing through structures such as the ribs 35 on the filter screen 32, it will be blocked, causing the included angle α to increase and the spring to be stretched to store energy. After passing over the blocking structure, the spring releases energy and returns to its original state, and the striking block 43 quickly strikes the filter screen 32 under the action of the spring elastic force. The continuous striking action can effectively shake off the impurities attached to the surface of the filter screen 32, avoid filter screen blockage, and maintain smooth filtration of the mixed material. At the same time, the buffering effect of the spring can reduce the impact force of the striking block 43 on the filter screen 32, reduce the risk of damage to the filter screen 32, and extend its service life.

[0050] The multiple groups of ribs 35 distributed on the filter screen 32 play multiple roles during the mixing material filtration process. The ribs 35 are arranged between the baffle 42 and the adjacent baffle 42. When the rotating sleeve 41 drives the baffle 42 to rotate, the striking members on the baffle 42 move accordingly. The ribs 35 can interact with the striking members and form a block on the striking members when the striking members pass through the ribs 35. This block causes the spring between the striking block 43 and the baffle 42 to be compressed or stretched, storing elastic potential energy. When the striking member passes over the ribs 35, the spring releases energy, driving the striking block 43 to strike the filter screen 32 with greater force, effectively removing the impurities attached to the surface of the filter screen and preventing the filter screen from being blocked. At the same time, the ribs 35 also enhance the overall strength of the filter screen 32, reducing the possibility of deformation or damage to the filter screen 32 when bearing the mixing material pressure and the impact force of the striking members.

[0051] The through slot 45 formed in the baffle plate 42, which is located above the striking block 43, provides space for the pretreatment of the mixed material. When the aluminum silicon carbide carbon brick mixed material enters the filtering link, the through slot 45 can guide part of the mixed material into its interior, changing the original flow path of the mixed material, so that the mixed material no longer moves only in a single direction, but forms a local flow diversion within the through slot 45, which helps to make more full use of the space in the filtering cavity and improve the filtering efficiency. The multiple groups of stirring plates 46 arranged in the through slot 45 further enhance the treatment effect on the mixed material. Stirring channels are formed between these stirring plates 46, and when the mixed material passes through this channel, it will be blocked and guided by the stirring plates 46. When the rotating sleeve 41 drives the baffle plate 42 to rotate, the stirring plates 46 move accordingly and continuously contact the mixed material. When the mixed material passes through the stirring channel, its flow direction and speed will change multiple times, and the large particle aggregates will gradually disperse under this repeated action, and the fine impurities can also be more fully exposed, significantly improving the uniformity of the mixed material.

[0052] The stirring plates 46 are arranged in a wavy shape. Compared with the ordinary flat plate shape, the undulating contour of its surface can have more contact and collision with the mixed material. At each convex and concave part of the wave, different-direction forces can be applied to the mixed material, causing the mixed material to generate complex turbulent flow motion. This motion mode can not only better disperse the particles in the mixed material, but also preliminarily screen the mixed material to a certain extent, separating some large particles that are likely to block the filter screen 32 in advance. At the same time, during the rotation of the wavy stirring plates 46, the frictional resistance with the mixed material can be reduced, the energy consumption can be lowered, and it is not easily worn by the mixed material itself, prolonging the service life and ensuring the long-term stable stirring treatment of the mixed material.

[0053] As Figures 3 to 5 、 Figure 8 、 Figure 12 shown, the water outlet ring 51 in the filtering cavity is installed in the feeding part and is a key component for realizing the cleaning of the filter screen. The connecting sleeve in the feeding hopper 22 cooperates with the bearing, enabling the water outlet ring 51 to rotate flexibly. The external water pump is connected to the water outlet ring 51 through a connecting pipe to convey the cleaning water into the interior of the water outlet ring 51. When the filter screen 32 needs to be cleaned, the water pump is started, and the water flow enters the water outlet ring 51, providing water source support for the flushing operation. The water outlet ring 51 can rotate around the bearing, and this characteristic enables the spray head 52 to cover a wider area, flushing the filter screen 32 from multiple angles, avoiding the appearance of flushing dead corners, and ensuring that all parts of the filter screen 32 can be effectively cleaned.

[0054] Multiple groups of spray nozzles 52 on the water outlet ring 51 form an included angle β of 45°-90° with each other. This layout makes the water flow sprayed by the spray nozzles 52 spread in a fan shape and impact the filter screen 32 from different directions. Multiple spray nozzles 52 work together, and the water flows intersect with each other, which can more effectively wash away the impurities attached to the surface and pores of the filter screen; multiple groups of spray nozzles 52 expand the flushing range, improve the flushing intensity, and enhance the cleaning effect. Even the fine impurities stuck deep in the filter screen can be loosened and shed under the impact of the multi-directional water flow, ensuring the permeability of the filter screen 32 and maintaining its good filtration efficiency.

[0055] The mounting plate 53 on the water outlet ring 51 cooperates with the swing groove 26 of the feed hopper 22, providing a structural basis for the swing of the water outlet ring 51. The mounting plate 53 is inserted into the swing groove 26, restricting the swing trajectory of the water outlet ring 51 so that it can stably perform the swing operation. The arc-shaped rack 27 on the mounting plate 53 meshes with the straight rack 28, and the electric cylinder 29 at the top of the feed hopper 22 drives the straight rack 28 to move. When the shaft end of the electric cylinder 29 expands and contracts, it drives the straight rack 28 to move in a straight line in the limit sliding groove. Through the meshing transmission between the racks, the linear motion is converted into the circular motion of the arc-shaped rack 27, and then the mounting plate 53 drives the water outlet ring 51 to swing in the swing groove 26. This transmission method can control the swing angle and amplitude of the water outlet ring 51, so that the flushing area of the spray nozzles 52 can be adjusted according to actual needs. There is a gap between adjacent spray nozzles 52, but the swing of the water outlet ring 51 can make the spray nozzles 52 switch between different positions, spraying the water flow to the area originally covered by the gap. For example, when the water outlet ring 51 swings to the left, the spraying range of the right spray nozzle 52 can cover the gap area of the left spray nozzle 52, and vice versa. Through this dynamic adjustment, the spraying ranges of the spray nozzles 52 complement each other, forming an overlapping cleaning area to ensure that there is no cleaning dead angle in the filter tank 21. During the cleaning process, the electric cylinder 29 can automatically adjust the swing speed of the water outlet ring 51 according to the degree of blockage. For severely blocked areas, the swing speed is reduced, so that the spray nozzles 52 stay in this area for a longer time, increasing the flushing frequency and water volume; for slightly blocked or unblocked areas, the swing speed is increased to achieve fast passing cleaning and improve the overall cleaning efficiency.

[0056] As Figure 6As shown, the mounting block 54 in the feeding section and the mounting frame 47 in the rotating sleeve 41 form a collaborative working system. The mounting frame 47 is distributed between the baffle 42 and the adjacent baffle 42, providing a fixed mounting position for the mounting block 54. When auxiliary cleaning of the filter screen 32 is required, the mounting block 54 can be snapped into the mounting frame 47, causing the mounting block 54 to rotate synchronously with the rotating sleeve 41. During the mixing and filtering process, the mounting block 54 can remain stable within the feeding section and will not sway or shift randomly due to the flow of the mixed material or the operation of the rotating sleeve 41, ensuring that the cleaning brush at its top always maintains an appropriate contact state with the filter screen 32, thereby continuously playing a cleaning role for the filter screen 32.

[0057] The mounting buckle 48 at the bottom of the mounting frame 47 and the mounting slot on the mounting block 54 cooperate with each other to achieve the detachable connection between the two. The mounting buckle 48 can be snapped into the mounting slot to firmly fix the mounting block 54 on the mounting frame 47, ensuring that the mounting block 54 will not fall off when the rotating sleeve 41 rotates at a high speed, enabling the cleaning brush to stably perform the cleaning operation on the filter screen 32. When the cleaning brush is worn and needs to be replaced, or when the mounting block 54 is damaged, the operator only needs to separate the mounting buckle 48 from the mounting slot to easily remove the mounting block 54 for replacement or repair. This detachable connection method greatly improves the convenience of equipment maintenance, shortens the equipment downtime for maintenance, and reduces the impact on the production schedule.

[0058] The cleaning brush at the top of the mounting block 54 is in direct contact with the surface of the filter screen 32 and plays a cleaning effect driven by the rotating sleeve 41. When the rotating sleeve 41 rotates, the mounting block 54 rotates accordingly, and the cleaning brush continuously sweeps across the surface of the filter screen 32, capable of brushing off impurities, caked mixed materials, etc. attached to the surface of the filter screen 32. Compared with relying solely on water flow flushing, the physical brushing action of the cleaning brush can more effectively remove stubborn impurities, especially the particles stuck in the filter mesh gaps. Moreover, the continuous brushing of the cleaning brush can, to a certain extent, prevent the accumulation and solidification of impurities on the surface of the filter screen 32, maintaining the cleanliness of the filter screen surface. At the same time, the contact between the cleaning brush and the filter screen 32 can also play a certain buffering role, reducing the direct impact of the striking part on the filter screen 32, lowering the risk of damage to the filter screen 32 due to frequent stress, extending the service life of the filter screen 32, and ensuring the long-term stable operation of the aluminum silicon carbide carbon brick mixing and filtering device.

[0059] Such as Figure 3 、 Figure 8 、 Figure 9As shown in the figure, the jitter tube 55 in the blanking section plays a key role in the process of discharging the mixed material. The outer diameter of the jitter tube 55 is smaller than the inner diameter of the filter tank 21, creating a movable gap between the two, which provides space for the movement of the jitter tube 55. The jitter tube 55 is connected to the filter tank 21 through multiple groups of springs. Springs have elastic properties. When the jitter tube 55 moves, they can not only limit its movement amplitude to prevent the jitter tube 55 from excessive deviation, but also provide a restoring force after the jitter tube 55 is stressed to ensure its stable jitter. When the filtered mixed material enters the jitter tube 55, the presence of the springs can prevent the jitter tube 55 from violently shaking due to the impact of the mixed material, maintaining the stability of the entire device. At the same time, the movable gap also facilitates observing the working state of the jitter tube 55 and performing maintenance operations when necessary.

[0060] An electromagnetic vibrator 57 is arranged in the installation through slot 56 on one side of the filter tank 21. The electromagnetic vibrator 57 is installed on one side of the jitter tube 55 and is the core component that drives the jitter tube 55 to work. When the electromagnetic vibrator 57 is powered on, it will generate high-frequency vibrations and transmit the vibrations to the jitter tube 55. Under the action of the electromagnetic vibrator 57, the jitter tube 55 generates high-frequency small-amplitude jitters. This kind of jitter can effectively break the arch structure or caking phenomenon formed by the mixed material during the falling process, prompting the mixed material to smoothly pass through the jitter tube 55 and discharge downward. The electromagnetic vibrator 57 can adopt an EM - G30 electromagnetic vibrator. Especially for some mixed materials with viscosity or easy to agglomerate, the vibration of the jitter tube 55 can disperse them, reduce the blanking resistance, and increase the blanking speed. In addition, the vibration of the jitter tube 55 can also play a role in shaking off the mixed material adhering to its inner wall, preventing material residue, ensuring that each blanking is relatively thorough, reducing material waste, and at the same time avoiding the influence of residual materials on the next filtration and blanking process, ensuring the efficient operation of the blanking link of the aluminum silicon carbide carbon brick mixed material filtering device.

[0061] The barrier ring 36 in the filter tank 21 is arranged in the blanking section, and the inclined surface at its top plays a guiding role during the falling process of the mixed material. When the mixed material enters the blanking section from below the filter sleeve 31, the inclined surface can guide the mixed material to spread evenly around, avoiding the mixed material concentrating on impacting the inlet of the jitter tube 55 and reducing the problem of unsmooth blanking caused by excessive local pressure. At the same time, the inner diameter of the barrier ring 36 is larger than the inner diameter of the jitter tube 55, forming an annular transition space, so that the mixed material has a buffer before entering the jitter tube 55, reducing the direct impact force of the mixed material on the jitter tube 55, protecting the jitter tube 55 and its connected spring structure, and extending the service life of the equipment. In addition, the barrier ring 36 can also block larger impurity particles from entering the jitter tube 55, preventing foreign objects from blocking the inside of the jitter tube 55 and ensuring the smoothness of the blanking channel.

[0062] The air outlet ring 37 inside the blanking section is connected to the filter tank 21 and is located between the barrier ring 36 and the shaking pipe 55, and is connected to an external air pump through a pipeline. When the air pump works, air is transported through the inside of the air outlet ring 37 to the annular air outlet 38 at the bottom. The diameter of the annular air outlet 38 is larger than the inner diameter of the shaking pipe 55 and smaller than the inner diameter of the barrier ring 36. This dimensional relationship enables the airflow ejected from the annular air outlet 38 to form a horizontal airflow wall above the entrance of the shaking pipe 55. On the one hand, this airflow wall can prevent the dust in the mixed material from surging upwards, avoiding the dust entering the feeding section and polluting the mixed material to be filtered, and improving the working environment; on the other hand, the impact force of the airflow can assist the mixed material to accelerate its falling. Especially for the mixed material with a relatively large viscosity, the airflow wall can weaken the adhesion between the material particles, and cooperate with the vibration of the shaking pipe 55 to further improve the blanking efficiency.

[0063] The airflow direction of the annular air outlet 38 is perpendicular to the falling direction of the mixed material, forming a dynamic barrier. When the mixed material enters the airflow wall area through the inclined surface of the barrier ring 36, the airflow will have a certain lifting and dispersing effect on the mixed material, making the mixed material further loose before entering the shaking pipe 55 and preventing caking. At the same time, the airflow wall can preliminarily sort the fine particles in the mixed material. The lighter dust is carried by the airflow towards the inner wall of the filter tank 21 and settles, while the heavier qualified mixed material passes through the airflow wall and enters the shaking pipe 55, improving the purity of the blanking. In addition, the structural design of the air outlet ring 37 is convenient for disassembly and cleaning, and the accumulated dust inside can be removed regularly to ensure smooth air flow, maintain the stable effect of the airflow wall, and ensure the long-term reliable operation of the entire blanking system.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
