Description

Technical Field

[0001] The invention belongs to the technical field of foam ceramic processing, and in particular relates to a foam ceramic processing device and a processing technology. Background Art

[0002] Ceramic foam filters are typically made by filling a polyurethane foam sponge with ceramic slurry, then squeezing out the slurry. This leaves a ceramic coating surrounding the foam sponge, which is then sintered at high temperatures. The polyurethane foam decomposes under the heat, leaving behind a foam-like ceramic product. This porous structure allows for efficient filtering of inclusions from molten metal, improving the quality and yield of metal castings.

[0003] Ceramic slurry is a mixture of ceramic powder and water. The ceramic powder is generally composed of a base material (silicon carbide, silicon dioxide, and aluminum oxide) and auxiliary materials (binders and dispersants). Silicon carbide offers excellent strength and resistance to high-temperature impact and chemical corrosion, with a temperature resistance of approximately 1600°C. Therefore, it is suitable for casting all copper alloys and cast iron. Ceramic foam filters can significantly improve the quality of cast iron parts and reduce scrap rates. They can also be used in continuous casting and rolling processes and can be manufactured in all standard sizes and varying thicknesses.

[0004] The polyurethane foam used in the production of conventional foam ceramic filters is mostly imported, resulting in high production costs. Furthermore, the production of double-layer foam ceramic filters suffers from the problem of low concentricity between the upper and lower layers.

[0005] In order to reduce the production cost of foam ceramic filter screens and improve the concentricity of the upper and lower foam ceramic layers in a double-layer foam ceramic filter screen, it is necessary to provide a new foam ceramic filter screen processing device and processing method. Summary of the Invention

[0014] The process for producing foam ceramics using a foam ceramic processing device comprises the following steps:

[0015] Step 1: Adsorbing ceramic powder: Fill the mixing box on the first batter conveyor line and the mixing box on the second batter conveyor line with foam particles of different sizes, then fill the mixing box with ceramic powder, and stir evenly to obtain a mixed material, wherein the particle size range of the foam particles in the mixing box on the second batter conveyor line is larger than the particle size range of the foam particles in the mixing box on the first batter conveyor line;

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example

[0034] Reference Figure 1-5 As shown, this embodiment provides a foam ceramic processing device, comprising a first paste conveyor line 1, a second paste conveyor line 2, and a forming conveyor line 3. Both the first paste conveyor line 1 and the second paste conveyor line 2 include a paste frame 101, on which a flattening assembly 102 and a paste assembly 103 are sequentially arranged along the conveying direction. The flattening assembly 102 is connected to the outlet of a mixing box 1021 at one end away from the paste assembly 103. The mixing box 1021 is used to evenly mix foam particles and ceramic powder, wherein the foam particles have different particle sizes, and the particle size range of the foam particles is selected based on the filtering requirements. The forming conveyor line 3 includes a forming frame 301, on which a forming conveyor mesh belt 302 is mounted. The conveying surface of the forming conveyor mesh belt 302 is provided with evenly distributed protrusions 303. The protrusions 303 are adapted to the socket structure on the bottom surface of the forming box 304. The protrusions 303 and the socket are used to achieve a rotational connection between the forming box 304 and the urban and rural conveyor belt. Gear 4 is fixedly connected to the curved outer wall of the forming box 304. Directly above the forming conveyor mesh belt 302, along its conveying direction, are located the discharge port of the first batter conveyor line 1, the first compacting assembly 305, the discharge port of the second batter conveyor line 2, the second compacting assembly 306, a sweeper 308, and a drying chamber 307. The first and second compacting assemblies 305 and 306 are used to prevent the formation of blank areas within the forming box 304. Within the drying chamber 307, a rack 5 and a fan 6 are fixed relative to the forming frame 301. The rack 5 and gear 4 are structurally compatible, and their combined use drives the rotation of the forming box 304.

[0035] During use, foam particles of different sizes are filled into the mixing box 1021 on the first paste conveyor line 1 and the mixing box 1021 on the second paste conveyor line 2, wherein the particle size range of the foam particles in the mixing box 1021 on the second paste conveyor line 2 is larger than the particle size range of the foam particles in the mixing box 1021 on the first paste conveyor line 1, the foam particles on the first paste conveyor line 1 and the second paste conveyor line 2 are flattened at the flattening component 102, wrapped with ceramic slurry of appropriate thickness at the paste component 103, and dried and shaped on the forming conveyor line 3, wherein the fan 6 can realize rapid drying of the ceramic slurry on the surface of the foam particles, and the coordinated use of the gear 4 and the rack 5 can ensure the uniformity of drying, and the mesh size of the forming conveyor belt 302 is larger than the maximum size of the foam particles used, so that excess foam particles leak out for recycling.

[0036] When using this application, two polyurethane foam sponges can also be stacked in the molding box 304, and the molding box 304 is used to ensure the concentricity and product performance of the two polyurethane foam sponges, and then they are transported by the molding conveyor line 3. During the transportation process, the rack 5 and the gear 4 are used in conjunction to enable the two stacked polyurethane foam sponges to rotate synchronously, thereby ensuring that the stacked polyurethane foam sponges can be dried evenly and efficiently in the drying chamber 307.

[0037] In a further preferred embodiment, the flattening assembly 102 includes a flattening conveyor mesh belt 1022 mounted on a frame. The mesh size of the flattening conveyor mesh belt 1022 is smaller than the minimum size of the foam particles it conveys, thereby preventing the foam particles from leaking out of the flattening conveyor mesh belt 1022 and allowing excess ceramic powder to leak out for recycling. A flattening member 1023 and a first distributor 1024 are provided in sequence above the flattening conveyor mesh belt 1022 along its conveying direction. The first distributor 1024 is used to spread ceramic powder onto the flattening conveyor mesh belt 1022. The distance from the bottom end of the flattening member 1023 to the conveying surface of the flattening conveyor mesh belt 1022 is no more than 1.5 times the maximum particle size of the foam particles conveyed on the flattening conveyor mesh belt 1022.

[0038] During use, the flattening piece 1023 can be connected to the frame through a lifting and adjusting cylinder, which makes it convenient to adjust the height of the flattening piece 1023 according to the maximum particle size of the foam particles. After the foam passes through the flattening piece 1023, the first distributor 1024 can be used to fill the surface ceramic powder loss caused by the contact between the foam particles and the flattening piece 1023.

[0039] In a further preferred embodiment, the batter coating assembly 103 includes a wetting conveyor mesh belt 1031 and a powder-binding conveyor mesh belt 1032, which are alternately connected along its conveying direction. The sum of the number of wetting conveyor mesh belts 1031 and powder-binding conveyor mesh belts 1032 is an odd number not less than 5. Spray devices 1033 are provided on both the upper and lower sides of the wetting conveyor mesh belt 1031, facing the wetting conveyor mesh belt 1031. The spray devices 1033 are used to wet the surface of the foam particles, thereby converting the ceramic powder on the surface of the foam particles into a ceramic slurry. The spray devices 1033 may include a water tank and a water mist nozzle connected to the water tank, with the water mist nozzle facing the wetting conveyor mesh belt 1031. The height of the sticky powder conveyor mesh belt 1032 gradually decreases along its conveying direction. A uniformly distributed second distributor 1034 is provided directly above the sticky powder conveyor mesh belt 1032. The height design of the sticky powder conveyor mesh belt 1032 enables the foam particles on the sticky powder conveyor mesh belt 1032 to roll, thereby enabling the ceramic powder spread by the second distributor 1034 to be evenly spread on the surface of the foam particles.

[0040] A first shifting assembly 1035 is provided at the junction of the conveying end of the moistening conveyor mesh belt 1031 and the conveying start of the powder sticking conveyor mesh belt 1032. This assembly ensures that foam particles can be smoothly transferred from the moistening conveyor mesh belt 1031 to the powder sticking conveyor mesh belt 1032. A second shifting assembly 1036 is provided at the junction of the moistening conveyor mesh belt 1031 and the flattening conveyor mesh belt 1022. This assembly ensures that foam particles can be smoothly transferred from the flattening conveyor mesh belt 1022 to the moistening conveyor mesh belt 1031. A third shifting assembly 1037 is provided at the junction of the moistening conveyor mesh belt 1031 and the forming conveyor mesh belt 302. This assembly ensures that foam particles can be smoothly transferred from the moistening conveyor mesh belt 1031 to the forming conveyor mesh belt 302.

[0041] During use, the mesh size of the wetting conveyor mesh belt 1031 and the powder sticking conveyor mesh belt 1032 is smaller than the minimum size of the foam particles they convey, thereby preventing the foam particles from leaking out of the flattening conveyor mesh belt 1022, while allowing excess water or ceramic powder to leak out for recycling. A buffer plate is provided between the flattening conveyor mesh belt 1022, the wetting conveyor mesh belt 1031, and the powder sticking conveyor mesh belt 1032 to prevent the foam particles from getting stuck at the connection between any two conveyor mesh belts. The slurry coating component 103 can coat the foam particles with a certain thickness of ceramic slurry, and the first conveying component 1035, the second conveying component 1036, and the third conveying component 1037 can ensure that the foam particles are smoothly moved from one conveyor mesh belt to another.

[0042] In a further preferred embodiment, the first, second, and third feeder assemblies 1035, 1036, and 1037 each include a third feeder 10351 and a lever 10352. The first, second, and third feeders 1024, 1034, and 10351 are all conventionally designed and may comprise a material box secured to the battering frame 101, with a feed opening at its bottom. A feed shaft adapted for its structure is located within the feed opening. One end of the shaft is connected to a feed motor secured to the side wall of the material box. The curved sidewall of the shaft is provided with feed grooves evenly distributed along the circumference. The lever 10352 is located directly below the feed opening and is positioned perpendicular to the material conveying direction. Both ends of the lever 10352 are rotatably connected to the battering frame 101, while one end of the lever 10352 is connected to a toggle motor secured to the battering frame 101. The curved side wall of the shifting rod 10352 is provided with shifting leaves 10353 evenly distributed along the circumferential direction. The shifting leaves 10353 can be composed of a plurality of rubber rods.

[0043] During use, the cloth motor drives the cloth shaft to rotate. When the cloth trough rotates to a downward position with the cloth shaft, the ceramic powder in the cloth trough can be sprinkled onto the shifting rod 10352 and the shifting blade 10353. The shifting rod 10352 rotates under the drive of the shifting motor, and the shifting blade 10353 rotates with the shifting rod 10352, thereby realizing the shifting of the foam particles. During the shifting, since the shifting blade 10353 is adhered to the ceramic powder, it can effectively prevent the shifting blade 10353 from knocking off the ceramic powder or ceramic slurry on the surface of the foam particles when it comes into contact with the foam particles.

[0044] In a further preferred embodiment, the top surface of the mixing box 1021 is provided with an inlet 7 and a stirring motor 8. A stirring roller connected to the stirring motor 8 is provided inside the mixing box 1021. A discharge pipe 9 is provided at the bottom of the mixing box 1021. The bottom of the discharge pipe 9 has an outlet, and a valve is provided inside the discharge pipe 9. During use, the stirring motor 8 can drive the stirring roller to rotate to achieve uniform mixing of the foam particles and the ceramic powder, and the valve can control the discharge speed of the mixing box 1021.

[0045] In a further preferred embodiment, forming box 304 is a hollowed-out cylindrical foam box. The diameter of the holes in forming box 304 should be smaller than the smallest foam particle to prevent foam particles from leaking out of forming box 304. The hollowed-out shape also facilitates drying of the ceramic slurry. A material trough 10 is provided on the top surface of forming box 304. The diameter of material trough 10 is no larger than the width of the discharge opening of the first and second coating conveyor lines 1 and 2. Material trough 10 is used to hold the coated foam particles, thereby achieving the desired shape of the foam ceramic.

[0046] In a further preferred embodiment, both the first compacting assembly 305 and the second compacting assembly 306 include a lifting plate 3051, each of which is fixedly connected to the forming frame 301 via a lifting power unit 3052. A pressure block 3053 adapted to the structure of the material trough 10 is provided on the bottom surface of the lifting plate 3051. The pressure block 3053 is capable of lifting and lowering under the action of the lifting power unit 3052. When lowered, it compacts the foam particles within the forming box 304. When raised, the foam particles recover their micro-deformation under their own action, thereby preventing the formation of empty material areas within the forming box 304.

[0047] The process for producing foam ceramics using a foam ceramic processing device comprises the following steps:

[0048] Step 1: Adsorbing ceramic powder: Fill foam particles of different sizes into the mixing box 1021 on the first batter conveyor line 1 and the mixing box 1021 on the second batter conveyor line 2, and then fill ceramic powder into the mixing box 1021. Stir evenly to obtain a mixed material, wherein the particle size range of the foam particles in the mixing box 1021 on the second batter conveyor line 2 is larger than the particle size range of the foam particles in the mixing box 1021 on the first batter conveyor line 1; the particle size range of the foam particles is selected according to the filtering requirements.

[0049] Step 2: Flattening: Transfer the mixed material to the flattening component 102 to flatten the foam particles contaminated with ceramic powder;

[0050] Step 3: Coating: The flattened foam particles are transferred to the coating assembly 103 so that the thickness of the ceramic slurry on the surface of the foam particles meets the use requirements. Then, the coating assembly 103 on the first coating conveyor line 1 transfers the coated foam particles to the discharge port of the first coating conveyor line 1, and the coating assembly 103 on the second coating conveyor line 2 transfers the coated foam particles to the discharge port of the second coating conveyor line 2;

[0051] Step 4: Molding: Manually insert the molding box 304 onto the protruding post 303 on the molding conveyor mesh belt 302. The molding box 304 is conveyed by the molding conveyor mesh belt 302 and passes through the discharge port of the first batter conveyor line 1, the first compacting assembly 305, the discharge port of the first batter conveyor line 1, the second compacting assembly 306, the sweeping member 308 and the drying chamber 307 in sequence. The first compacting assembly 305 and the second compacting assembly 306 press the foam particles in the molding box 304 down for a distance and then reset them to prevent the formation of an empty material area in the molding box 304. The sweeping member 308 sweeps away excess foam particles on the top surface of the molding box 304. The drying chamber 307 can dry the ceramic slurry on the surface of the foam particles to obtain a shaped embryo body.

[0052] Step 5: Place the shaped embryo together with the forming box 304 into a high-temperature furnace for sintering to obtain a foam ceramic filter product;

[0053] Step 6: Pack the foam ceramic filter.

[0054] Therefore, the present invention adopts a foam ceramic processing device and processing technology of the above structure, which can reduce production costs, facilitate the production of a double-layer foam ceramic filter, and at the same time ensure the concentricity of the two layers of foam ceramic filter.
