Description

Technical Field

[0001] This utility model relates to the field of foam ceramic processing technology, and more specifically, it relates to a foam ceramic impurity filtration device. Background Technology

[0002] Filtration is an essential core step in the production and processing of foam ceramics, primarily during the slurry preparation stage. This step directly affects the quality and performance of the finished foam ceramic. The ceramic slurry is composed of refractory aggregates (such as silicon carbide and alumina), binders, and additives. During mixing, uncrushed particles, clumps, or air bubbles may be introduced. Failure to filter will lead to voids or stress concentration points within the green body, resulting in cracking and insufficient strength after sintering. The slurry needs to have a high solids content (50%~65%) and good thixotropy. Filtration eliminates agglomerated particles, ensuring the slurry adheres uniformly to the foam carrier and preventing uneven mesh structure after sintering.

[0003] Existing filtration devices use single-pore size filter screens. If the pore size is too small, it is easily clogged quickly by clustered impurities, causing a sharp drop in filtration throughput. If the pore size is too large, it cannot intercept small clusters, and these impurities enter the subsequent forming process. Furthermore, the filtration process cannot automatically clean the impurities after filtration, and the filtered impurities accumulate in the filter frame, requiring manual cleaning.

[0004] Therefore, we propose a foam ceramic impurity filtration device. Utility Model Content

[0005] The present invention aims to provide a foam ceramic impurity filtration device to solve the technical problem in the prior art where slow filtration is caused by incomplete manual cleaning after long-term use of a single filter screen.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A foam ceramic impurity filtration device includes a support base with a bracket. A filter tank is rotatably connected inside the bracket. Both ends of the filter tank are sealed and connected to connecting pipes. Filter screens are spaced apart inside the filter tank. Several sliders are evenly distributed around the circumference of the filter screens. A sliding groove is provided on the inner wall of the filter tank for the sliders to slide. The sliders are fixedly connected to both ends of the sliding groove by springs.

[0008] Preferably, a motor is mounted on the side of the support base, and the output shaft of the motor is provided with a bevel gear one. The bevel gear one meshes with a bevel gear two that is rotatably engaged with the support base. The bevel gear two is coaxially provided with a bevel gear three. The bevel gear three meshes with a bevel gear four that is rotatably engaged with the bracket. The bevel gear four and a connecting pipe are connected to a belt through a coaxially arranged pulley.

[0009] Preferably, a rotating shaft is provided between the second and third bevel gears, and the two sides of the bracket are rotatably engaged with the support base via support rods. One of the support rods is movably fitted with a fastener, and the fastener is threadedly connected to the rotating shaft.

[0010] Preferably, the rotation direction of the shaft is opposite to the tightening direction of the fastener.

[0011] Preferably, the filter screen is inclined.

[0012] Preferably, there are at least two filters with different pore sizes.

[0013] Preferably, the two adjacent filter screens are tilted in opposite directions.

[0014] Preferably, the number of sliders is four.

[0015] Preferably, the filter tank has a viewing window.

[0016] Preferably, a solenoid valve is provided inside the connecting pipe.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This invention, through ingenious design, enables a motor-driven filter tank to rotate. The rotating filter tank, in turn, causes the filter screen to rotate. Due to centrifugal force, the rotating filter screen vibrates under the action of a spring, thereby increasing the filtration speed of the slurry. Furthermore, the rotating filter screen improves the uniformity of contact between the filter screen surface and the slurry, preventing localized blockage caused by excessive slurry in certain areas, thus improving filtration efficiency.

[0019] 2. By setting adjacent filter screens in opposite directions, the residence time of the slurry on the filter screen can be increased, thereby improving the filtration effect. In addition, after filtration, the direction of the filter tank can be reversed through clever design, so that the side of the filter screen faces down; under the action of centrifugal force, the filter screen vibrates, thereby achieving automatic cleaning and removal.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1 to 4 As shown, a foam ceramic impurity filtration device includes a support base 1. Support plates are provided at both ends of the top of the support base 1, and a bracket 2 is provided between the two support plates. A filter tank 3 is rotatably connected inside the bracket 2. Connecting pipes 4 are sealed and connected to both ends of the filter tank 3. An inlet pipe and an outlet pipe are detachably and rotatably connected to the two connecting pipes 4, respectively. Two filter screens 5 with different apertures are spaced apart inside the filter tank 3. Four sliders 6 are distributed around the circumference of the filter screens 5. A groove 7 is provided on the inner wall of the filter tank 3 for the sliders 6 to slide. The sliders 6 are fixedly connected to both ends of the groove 7 by springs.

[0028] As a preferred embodiment, a motor 8 is mounted on the side of the support base 1. The output shaft of the motor 8 is provided with a bevel gear 9. The bevel gear 9 meshes with a bevel gear 10 that is rotatably engaged with the support plate. The bevel gear 10 is coaxially provided with a bevel gear 11. The bevel gear 10 and the bevel gear 11 are located on opposite sides of the same support plate. The bevel gear 11 meshes with a bevel gear 12 that is rotatably engaged with the bracket 2. The bevel gear 12 and a connecting pipe 4 are fitted with a belt 13 through a coaxially arranged wheel.

[0029] As another preferred embodiment, a rotating shaft 14 is provided between bevel gear 2 10 and bevel gear 3 11. The two sides of the bracket 2 are rotatably engaged with the support plate by support rods 15. A fastener 16 is movably sleeved on one of the support rods 15 near the rotating shaft 14. The fastener 16 has an internal thread that matches the external thread of the rotating shaft 14.

[0030] As another preferred embodiment, the rotation direction of the rotating shaft 14 is opposite to the fastening direction of the fastener 16.

[0031] As another preferred embodiment, the filter 5 is inclined.

[0032] As another preferred embodiment, the two filters 5 are tilted in opposite directions.

[0033] As another preferred embodiment, a solenoid valve 17 is provided inside the connecting pipe 4.

[0034] As a preferred embodiment, in order to facilitate observation of the cleaning status of impurities on the filter screen 5, a viewing window 18 can be opened in the direction of the filter surface of the filter tank near the filter screen 5.

[0035] As a preferred embodiment, in order to prevent the rotating filter tank 3 from swinging back and forth, another support rod 15 extends out of the support plate and is fitted with a fastening nut (not shown in the figure).

[0036] Working principle and usage process:

[0037] In use, the larger-aperture filter screen 5 is positioned above the smaller-aperture filter screen 5. The upper connecting pipe 4 is detachably and sealed to the feed pipe, and the lower connecting pipe 4 is detachably and sealed to the discharge pipe. Simultaneously with feeding, the motor 8 is started, driving the first bevel gear 9 to rotate. With the cooperation of the second bevel gear 10, the third bevel gear 11, the fourth bevel gear 12, and the belt 13, the filter tank 3 rotates. The rotating filter tank 3 drives the filter screen 5 to rotate. Due to centrifugal force, the rotating filter screen 5 vibrates under the action of the spring, thereby increasing the filtration speed of the slurry. Furthermore, the rotating filter screen 5 improves the uniformity of contact between the filter screen 5 and the slurry, preventing localized blockage due to excessive slurry and thus improving filtration efficiency. Moreover, the two filter screens 5 are arranged with opposite tilt directions, increasing the residence time of the slurry on the filter screens 5, thereby improving the filtration effect. The intercepted impurities are located at the lower part of the filter screen 5, thus not affecting the filtration effect of the higher filter screen 5. Larger impurities are trapped on the upper filter screen 5, while smaller impurities are trapped on the lower filter screen 5.

[0038] After filtration, fastener 16 is threaded onto shaft 14, allowing the filter tank to be rotated so that the side of filter screen 5 faces downwards, with the larger pore size filter screen 5 positioned below the smaller pore size filter screen 5. This allows impurities trapped by the smaller pore size filter screen 5 to easily pass through and be removed. During cleaning, unthread fastener 16 is disconnected from shaft 14, leaving only the filter tank 3 rotating. Centrifugal force causes the filter screen 5 to vibrate, automatically cleaning and discharging impurities.

[0039] The impurities on the filter screen 5 can be checked through the viewing window 18 to see if they have been cleaned. If stubborn impurities are stuck to the filter screen 5, clean water is pumped into the filter tank 3, the solenoid valves 17 connecting both ends of the tank are closed, the feed pipe and discharge pipe are disassembled, and the fastener 16 is threaded to the rotating shaft 14, so that the filter tank 3 rotates itself and rotates with the bracket 2; thus, the impurities attached to the filter screen 5 can be removed. After the stubborn impurities are removed from the filter screen 5, the direction of the filter tank is reversed so that the filtering side of the filter screen 5 is facing down, the feed pipe and discharge pipe are connected, the solenoid valve 17 is opened, and the impurities are discharged, achieving automatic and efficient cleaning.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
