Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of ceramic wall and floor tile production, and specifically relates to a wet low-carbon production process equipment for ceramic tile blanks that does not require dry granulation and wet granulation processes, in particular to a direct and efficient wet low-carbon production process equipment for full-textured rock slabs. Technical Background
[0002] Ball milling, spray drying, pressing, and firing are the four key processes in ceramic tile production, all of which are energy-intensive. Typically, the moisture content of the milled slurry is around 33-38%, while the moisture content of the powder used for pressing is around 7%. The heat energy consumed in spray drying the slurry to powder is second only to the energy consumption of firing, accounting for approximately 80% of this process's energy consumption. Spray drying is energy-intensive and also creates environmental pollution issues. Ceramic factories invest heavily in environmental governance. There are two main types of existing ceramic dry powder production methods, such as patent document patent publication number CN115745629A "Ceramic Powder Preparation Method" and CN114454332A "Ceramic Dry Powder Production". The key steps of the process are: 1. The homogenized mud is pressed into a mud cake, and the filtrate is concentrated into filter pulp for reuse; 2. The mud cake is refined into mud blocks or mud particles and then dried to a moisture content suitable for subsequent processing requirements, and the reused filter pulp is added during the process; 3. The mud blocks or mud particles are impact-crushed into mud powder and then iron is removed. There are also dry pulverization processes similar to existing cement raw material grinding processes, using a vertical roller mill to grind the ceramic raw materials and then adding water to granulate and harden them into the desired particles. Representative companies include LB in Italy, Eirich in Germany, and Atotor in the UK. Patents include Patent Publication No. CN115890893A, "Method and Apparatus for Preparing Ceramic Tiles Using Dry Pulverization," and wet and dry pulverization processes, such as Patent Publication No. CN110407587A, "A Dry and Wet Pulverization Process for Architectural Ceramics." Existing dry and wet ceramic pulverization methods are also traditional pulverization methods in the ceramics industry. They also reduce energy consumption, eliminate the need for desulfurization towers, and significantly reduce carbon emissions. The main steps of existing ceramic plastic extrusion methods for forming blanks are: 1. Pressing the homogenized slurry into a cake; 2. Refining the cake into blocks or pellets, drying them to a moisture content suitable for subsequent processing, extruding the desired blanks using a vacuum extruder, and then drying and firing them.
[0003] The usual production of full-textured ceramic wall and floor tiles is done by grinding the ceramic raw materials into a slurry and then spray drying it to form powder particles of various colors, which are then passed through various rollers with various patterned fabrics to form ceramic blanks; or by using digital ceramic powder particles using digital powder spraying equipment to press patterned fabrics to form a full-textured ceramic blank. Technical issues
[0004] At present, the main defects of this process are: 1. Spray drying powder production has high energy consumption and complicated process flow. It is necessary to directly pass the slurry with a moisture content of about 33-38% through the spray tower to dry it into powder with a moisture content of about 5-8%. In particular, digital ceramic powder has specific requirements on the moisture content and fluidity of the slurry, and requires extremely strict moisture content. It takes about 43 cubic meters of standard natural gas and about 75 kg of coal to obtain each ton of powder. This drying and dehydration process will consume a lot of heat energy and produce more carbon dioxide emissions; 2. The production process of powders manufactured by dry and wet methods is complicated. The colors of a natural stone are extremely rich, with at least three colors and as many as four, five, seven or eight colors and transition colors. If you want to get rich and colorful, naturally variable colors, you need to configure the corresponding color powder, which also makes the spray tower operation cumbersome and the production process of various color powders complicated. 3. Since it is a solid particle powder for pattern pressing and molding production Process, although now have adopted various digital powder spraying equipment technical means, but the obtained product pattern and color are still rough and unnatural, without the inherent beauty of natural stone, the main problem is the powder particles are mixed, the color boundary of the powder particles is obvious, there is no gradient, no transition between colors, they are independent and incompatible with each other, and do not have the delicate texture of natural stone, which makes the product lack visual beauty and is far from natural stone. 4. The pattern of ceramic plastic extrusion blank is rough and the pattern texture is difficult to change. It requires a large proportion of scarce plastic clay. The cost of high-quality plastic clay raw materials is high, the process is numerous and complicated, and the density of the finished brick blank is low. 5. The dry pulverizing and wet filter pressing pulverizing processes are cumbersome and complicated, the powder particle size distribution is uneven, the fluidity is poor, the particle density ratio fluctuates greatly, the brick blank quality rate is low, the dust pollution is serious, and the transportation between dry powders makes the working environment harsh, increases the management cost, and can only make ordinary coarse ore ceramic brick blanks.
[0005] Including prior art documents, a device for forming a desired pattern on a tile from a slurry, characterized in that it includes a device for preparing the slurry; at least one slurry storage tank for storing at least one type of slurry; at least one pattern forming tray; at least one device for connecting the at least one tank to the at least one pattern forming tray; and a filter pressing device; wherein the pattern forming device dispenses slurries of predetermined types, material amounts, and colors in a predetermined order to form the desired pattern, and the slurry with the desired pattern is pressed in the filter pressing device to form a tile or slab with the desired pattern throughout its entire thickness. The pattern obtained in this document is rough, not smooth, and not delicate, and the switching is relatively complicated. The filter pressing technology can only produce intermittent body texture patterns. There is only a single filter pressing module, the dehydration efficiency is low, and the technical means are difficult to control. The slurry color is easy to branch and flow chaotically, and it is not easy to repeat production. Moreover, this technology has been disclosed for nearly 20 years. This technical method solution is not recognized and accepted by technical personnel in this field. Due to the technical prejudice of technical personnel in this field, they turn a blind eye to it and neither apply it nor improve it. Of course, the starting point, motivation and technical problem to be solved of this technical solution is to provide a device and method for forming a pattern in a ceramic tile with a specified thickness that imitates the pattern texture of a natural rock formation. Another purpose is to use a device according to the principle described here to enable the obtained ceramic tile or slab to achieve consistent thickness and size. The starting point, motivation and main technical problem to be solved of this application are essentially different from those of this technical solution. Technical personnel in this field have been using the traditional granulation process to improve process technology, and have not actively explored and proposed the theme of the process and equipment for manufacturing bricks without the need for dry granulation process and direct wet filtration without the need for wet granulation process, so as to achieve the production goals of significantly saving processes, reducing costs, increasing efficiency, saving carbon and reducing emissions. Technical solution (content of the invention)
[0006] In response to the above production process defects and technical prejudices, the applicant provides a wet production process and equipment for directly manufacturing brick blanks without dry granulation process and wet granulation process. It is also a production process and equipment scheme for a new low-carbon and low-cost solid rock slab with variable color and natural texture. The present invention provides a wet production process equipment design scheme for granulation-free brick blanks, which is characterized by: the equipment mainly includes a digital slurry printing device, a continuous suction filtration, filter pressing device or an intermittent suction filtration punching filter press device, a drying kiln device, and a transmission device connected to each other between the equipment; the process flow and production process scheme between the equipment devices are: a high-concentration ceramic slurry is applied and formed by a digital ceramic mud printing device, and then suction filtration and filter pressing are performed by a continuous suction filtration, filter pressing device or an intermittent suction filtration punching filter press device to quickly dehydrate it into wet brick blanks with different moisture contents (moisture content is 5-13%), and then the wet brick blanks are directly dried and subjected to other conventional processes. Its process equipment further includes a digital slurry printing device, a belt vacuum negative pressure suction filter press device, a vacuum negative pressure high pressure dehydration device, a flash drying kiln device, a high pressure pressing molding device, and a transmission device interconnected between the equipment. Its equipment operation process and production process plan further include the use of a digital ceramic mud printing device to shape the slurry with a moisture content of about 20% to 38% on the filter belt or filter plate of the belt vacuum negative pressure suction filter press device, and then through the belt vacuum negative pressure suction filter press device, in the vacuum negative pressure The water content of the wet bricks is dehydrated by suction filtration and pressure filtration to form ultra-high wet bricks with a moisture content of about 16% to 22%, or the wet bricks are dehydrated to about 9% to 16% by a high-pressure filter press device under a vacuum negative pressure and a hydraulic cylinder oil pressure of 2.5 to 40 MPa. The water is then evaporated to 5% to 13% wet bricks by a flash drying kiln device. The bricks are then pressed into compact bricks according to different pressure requirements using a high-pressure pressing and forming device under a hydraulic cylinder oil pressure of 15 to 60 MPa according to different pressure requirements, and then dried and other conventional processes are carried out. The wet production process equipment design scheme of the granulation-free process bricks of the present invention can be used to perform multiple new process pattern decorations on the bricks with different moisture contents before and after the drying process in the wet production process of the ceramic brick body, such as cutting and splicing, spraying color powder slurry on the cracks, etc.The present invention provides a wet production process equipment design for granulation-free brick blanks, which is characterized in that the production of brick blanks includes the use of a continuous horizontal belt vacuum suction filter press dehydration device, and also includes a more complicated process equivalent to replacing it with a centrifugal dehydrator, a screw stacker, a non-horizontal belt, a plate vacuum suction filter press and other devices, which can also dehydrate the mud into an ultra-high wet brick blank mud paste with a moisture content of about 13% to 22%. It also includes the use of a more complicated process vacuum extruder to extrude high-wet brick blanks of the required specifications and then use a flash drying kiln device to evaporate the moisture into 5-13% wet brick blanks, and then use a high-pressure pressing molding device to perform high-pressure pressing with different pressure requirements to form dense brick blanks according to process requirements.
[0007] The present invention provides a wet production process equipment design for granulation-free bricks, and its digital ceramic slurry printing device can ensure that the thickness and pattern of each batch of bricks can be accurately produced, and standardized color matching is performed using three primary color slurries. The digital ceramic slurry printing device includes different slurry hoppers and uneven stirring and mixing devices, and is preferably mainly composed of multiple groups of identical spray module package systems to achieve high-precision pattern texture forming of bricks. The single-group spray module package system mainly includes a fixed frame, a storage hopper for holding spray-printed ceramic slurry, a multi-unit hole module plate for discharging slurry at the bottom of the storage hopper, a striker for controlling the opening and closing of the slurry unit hole, and an electric device for controlling the lifting and lowering of the striker. The digital ceramic glaze printing device is mainly installed with multiple groups of fixed frames, on which a storage hopper for holding the printed ceramic slurry is installed, and multiple groups of slurry discharge unit orifice plate modules are installed at the bottom of the storage hopper. A ejector pin device for controlling the opening and closing of the slurry discharge unit hole is installed in the storage hopper, and a piezoelectric ceramic component or electromagnet group device for controlling the lifting of the ejector pin is installed on the top or side of the ejector pin. The piezoelectric ceramic and electromagnet circuit signals of each unit are controlled by an integrated circuit control panel. The device is characterized in that the storage hopper includes at least two slurry tanks, and the unit holes of the slurry discharge unit orifice plate at the bottom of the storage hopper include a multi-channel structure, at least a three-channel structure, or the unit holes of the slurry discharge unit orifice plate are a structure for receiving multiple slurry channels, at least a channel structure for receiving two types of slurries.
[0008] The present invention discloses a wet-process equipment design for producing granulation-free bricks. The continuous horizontal belt vacuum filter press device primarily comprises a filter belt or microporous filter plate, a vacuum filter box, a vacuum tank, a drive roller, a horizontal roller, a driven roller, a filter press roller, a filter cloth deviation correction device, a drive device, a filter cloth cleaning device, a frame, and other components. This highly efficient device primarily utilizes material gravity and vacuum suction to achieve solid-liquid separation. Its operating principle is that a motor, after deceleration, drives the active roller to rotate, thereby driving the filter belt or microporous filter plate to continuously operate, or the filter cloth, which is tightly attached to the belt, operates synchronously with the belt under the action of vacuum. The annular friction belt under the filter cloth tape is in sliding contact with the vacuum filter box plate of the vacuum filter chamber (water is present between the vacuum chamber filter box plate and the annular friction belt to form a water seal). When the vacuum chamber filter box plate is connected to the vacuum system, the filter cloth or microporous filter plate forms a vacuum filtration area to dehydrate the slurry. The ceramic slurry is evenly added to the filter cloth or the belt filter plate by a digital ceramic slurry printing device. Under the action of vacuum, the filtrate passes through the small holes of the filter cloth and the microporous filter plate and enters the vacuum negative pressure collection chamber. The ceramic solid particles are intercepted and form a ceramic paste filter cake. The filtrate entering the vacuum negative pressure collection chamber is discharged through the gas and water separator. As the filter cloth belt and microporous filter plates advance, the formed ceramic paste filter cake enters the ceramic paste filter cake suction and filter press for further dehydration. Finally, the filter cloth belt and microporous filter plates remove the ceramic tiles, which are then cleaned and recycled. After passing through redirecting rollers and a correction device, they re-enter the filtration section. The resulting continuous, intact, and uniformly thick ceramic paste bricks are then transferred horizontally from the discharge port to the drying unit. The belt filter plates and vacuum adsorption chamber plates can be designed to move synchronously and then quickly reset. A dynamic seal is formed between the vacuum adsorption chamber plates and the belt filter plates, using vacuum pressure as the driving force to achieve solid-liquid separation. The pore size of commercially available filter press materials, such as filter cloth and ceramic templates, ranges from 50 microns to 0.05 microns. The pore size of the filter material is selected based on the particle size of the slurry being filtered, ensuring long-term filtration without leakage or clogging of the filter material pores.
[0009] The present invention provides a design scheme for wet production equipment of granulation-free brick blanks, wherein the drying kiln device includes a horizontal belt drying device or a vertical box drying device, and also includes a conventional horizontal belt drying kiln device, a single-layer and multi-layer stick drying kiln device, and a box vertical hanging basket and cage circulation drying device, wherein the belt drying device is composed of an insulating box, a conveyor chain and mesh belt, a chain and mesh belt tensioner, a dehumidification device, a transmission device, a conveyor belt, an indirect heating device, etc. The box vertical hanging basket and cage circulation drying device mainly includes a column, a connecting crossbeam, a connecting longitudinal beam, an electric control device, a synchronous moving device, a hanging cage, and a lifting device. The column is fixed to the connecting crossbeam and the connecting longitudinal beam, the electric control device is fixed to the side of the column, and the synchronous moving device is fixed to the column, so that the support plate in the hanging cage can be horizontally moved up and down inside the column through the electric control device and the synchronous moving device. The ceramic drying device is a relatively mature process drying equipment in this field. Those skilled in the art are familiar with its drying principle and drying heat source scheme. The drying process is indispensable in ceramic production, and the inventor will not make a detailed description.
[0010] The wet production process equipment design scheme of the granulation-free brick blank of the present invention has the following production process and process pressing parameter characteristics: in the existing ceramic blank formula system (the ceramic mud raw material accounts for about 20-40% of the total formula composition), the mud is filtered and filtered to make the mud blank uniformly wet with a moisture content of 5-16%, preferably with a uniform moisture content of 8-12%, and further preferably with a uniform moisture content of 7.5-9.5%, and then further high-pressure pressing is performed under the condition of 20-60Mpa hydraulic cylinder oil pressure to form a dense brick blank. The high-pressure press pressing process used includes static pressure pressing equipment and vibration pressing equipment, and static pressure pressing equipment is preferably such as the existing ceramic belt steel belt roller press and intermittent mold frame punch press. Among them, the intermittent mold frame stamping press is preferably a sliding mold frame stamping press. The sliding mold frame stamping press equipment is characterized by a sinking upper and lower sliding mold frame, preferably a trapezoidal sliding mold frame with a large lower inner width. For high-pressure stamping and dense pressing, the lower inner width of the mold frame is preferably 8 to 10 mm larger than the brick size, which is convenient for reducing the fitting accuracy and achieving rapid pressing. The feature of the sinking upper and lower sliding mold frame stamping press equipment is that the sliding mold frame can accurately correct the position of the brick to be pressed and the overlap of the lower mold core when it descends, and it is not easy to damage the brick. While when a fixed mold frame stamping press is used, the brick is easily stuck in the fixed mold frame and suspended in the air when its lower mold core descends, causing damage to the brick, and it is difficult to accurately correct the position of the brick to be pressed and the overlap of the mold core.
[0011] The wet production process equipment design scheme of the granulation-free brick blank of the present invention is characterized in that: the mud is directly dehydrated by a mechanical pressing method and the brick blank is directly manufactured. It is a unique ceramic wall and floor tile brick blank production process method. Different equipment and different process means in ceramic production are transformed and modified through special process changes and beneficially combined to form a new technical overall solution, which makes the entire ceramic production process extremely streamlined, abandons the traditional high-energy consumption evaporation dehydration, abandons the traditional high-energy consumption and high-pollution granulation, and abandons the traditional high-energy consumption and high-pollution dry powder pressing of brick blanks, thereby greatly improving production efficiency and significantly reducing production costs.

Its production process is to use a digital ceramic mud printing device to apply and shape high-concentration ceramic slurry and paste, and then use a horizontal belt vacuum suction filter press and a punch filter press device to dehydrate them into wet bricks with different moisture contents of 8% to 22% under the conditions of 0.2 to 40Mpa hydraulic cylinder oil pressure. The wet bricks are then dried to make the wet bricks have a uniform moisture content of 5 to 9%, or further high-pressure pressing is performed under the conditions of 10 to 60Mpa hydraulic cylinder oil pressure to form dense bricks. 2.

It is characterized in that the suction filtration, pressure filtration and punching filter press device mainly include a horizontal belt vacuum suction filtration filter press device, or (and) a punching filter press device, wherein the horizontal belt vacuum suction filtration filter press device is mainly composed of a belt filter belt tape or a belt microporous filter plate, a lower vacuum adsorption box plate, a connecting hose, a vacuum tank, a driving roller, a driven roller, a filter cloth, a filter plate correction device, a driving device, a filter cloth, a microporous filter plate cleaner and a washing device, and a frame component, and further includes an upper belt filter belt tape or a belt microporous filter plate, an upper vacuum negative pressure water vapor adsorption box plate, a connecting hose, an upper driving roller, an upper driven roller, upper and lower filter rollers, a driving device, a filter cloth, a microporous filter plate cleaner and a washing device, and a frame component; its punching filter press device is mainly composed of a mold frame, an upper filter press mold core, a lower filter press mold core, a positive and negative pressure water vapor blowing and suction device, and a frame component.

DETAILED DESCRIPTION
[0020] Example 1
[0021] The design scheme of wet production process equipment of a granulation-free brick blank of the present invention is shown in the attached figure. Figure 3 The ceramic mud raw material accounts for 30% of the total formula composition. The process is characterized in that a high-concentration slurry (2) with a water content of 31% is applied to a belt-type microporous filter plate through a slurry hopper (1) of a digital ceramic mud printing device, and reaches a slurry thickness of 22 mm required by the process. Then, a vacuum filter device vacuum suction box plate (3) is used to adsorb the bottom of the belt-type microporous filter plate to quickly vacuum dehydrate the 22 mm slurry layer into an ultra-high wet brick blank with a water content of about 20%. Then, the ultra-high wet brick blank with a water content of about 20% is squeezed horizontally downward by pressing the vacuum suction box plate (3-1) downward, and a progressive high-pressure roller pressure filter vacuum is performed under the oil pressure of a hydraulic cylinder of 0.5 to 5.0 MPa. After suction filtration, the bricks are quickly dehydrated into high-humidity green bricks with a moisture content of about 16%. The bricks are then cut and moved to a pallet using a mechanical arm. The bricks are then dried in a drying kiln (9) to a moisture content of 8.5-9.5%. The low-humidity green bricks with a moisture content of 8.5-9.5% are then fed into a stamping press lower die core (14) of equal size using a mechanical arm and accurately positioned. The press sliding die frame (13) whose lower inner width is 10 mm larger than the size of the green bricks and the lower die core is lowered to accurately frame the green bricks until the inner width is equal to the green brick size. The upper die core of the press is lowered and pressed, and two stamping presses are performed under the conditions of 10 MPa and 20 MPa hydraulic cylinder oil pressure to form dense green bricks. The pressing frequency is 18 green bricks per minute.

[0023] The design scheme of wet production process equipment of a granulation-free brick blank of the present invention is shown in the attached figure. Figure 1The ceramic mud raw material accounts for 40% of the total formula composition. The process is characterized by applying 6 colors of high-concentration color paste with a moisture content of 34% in multiple layers on a belt filter belt (4) through a digital ceramic mud slurry printing device, and achieving a slurry thickness of 25 mm required by the process. Then, the vacuum filter device vacuum suction box plate (3) slides and absorbs the bottom of the belt filter belt to quickly dehydrate the 25 mm slurry layer into an ultra-high wet brick with a moisture content of about 21%. The ultra-high wet brick is cut and pieced together many times, and the cracks are sprayed with color powder and color paste for new process pattern decoration, and then quickly subjected to 0.5-3.0Mpa liquid Under the hydraulic pressure of the cylinder, multiple groups of multi-stage downward pressure vacuum filter box plates (3-1) and multiple groups of filter rollers (17) are used for dehydration to form high-humidity bricks with a moisture content of about 17%, which are then moved horizontally to the stainless steel mesh belt of the drying kiln (9). The bricks are then dried in the horizontal drying kiln (9) to reduce the moisture content to 8.5-9.5%. The low-humidity bricks are then adjusted in size and shaped into the specified requirements before being sent to the high-pressure roller press belt (10). The belt roller press is used for gradual high pressure at 0.5-35 MPa hydraulic cylinder oil pressure and gradual release of high pressure at 35-0 MPa hydraulic cylinder oil pressure to form dense bricks.

[0025] The design scheme of wet production process equipment of a granulation-free brick blank of the present invention is shown in the attached figure. Figure 2The ceramic mud raw material accounts for 25% of the total formula composition. The process is characterized in that a high-concentration slurry (2) with a water content of 32% is quantitatively applied to a brick mold composed of a press lower mold core (14) and a press sliding mold frame (13) of a press with a filter press multi-hole mold core by a digital ceramic mud printing device through a slurry pipe (12).

The bottom of the lower mold core (14) of the lower press is fixed by a vacuum machine device to quickly dehydrate the slurry layer. At the same time, the movable filter press mold core on the stamping press squeezes the slurry layer downward to perform a progressive multi-stage downward pressure high-pressure filtration under the oil pressure of the hydraulic cylinder of 0 to 20 MPa. The upper movable filter press mold core is quickly dehydrated by vacuum negative pressure adsorption to press the high-humidity brick blank with a moisture content of about 11%. The pressing frequency is 8 brick blanks per minute. Then, the positive pressure water vapor blowing device is combined with the filter press mold core to demould. The lower filter press mold core is positively demoulded. The upper filter press mold core and the sliding mold frame rise and the positive pressure demould is performed. , and then it is moved horizontally to the receiving pallet through the mechanical arm suction cup, and then dried in a horizontal drying kiln to make the moisture content of 7.5-8.5%. Then the low-humidity brick is sent to the lower mold core of the stamping press of equal size through the mechanical arm suction cup and accurately positioned. The sliding mold frame with a lower inner width 10 mm larger than the brick and lower mold core size is lowered, accurately framing the brick until the inner width is equal to the brick size. The upper mold core of the press is lowered to perform two punching presses under the conditions of 10Mpa and 30Mpa hydraulic cylinder oil pressure to form a dense brick. The pressing frequency is 13 bricks per minute. Or as attached Figure 2The schematic diagram of the punching filter press is as follows: the two-color high-concentration slurry (2) with a water content of 26% is pumped from the side wall pipeline of the press sliding mold frame (13) through the uneven mixing device of the pipeline with inner spiral blades into the closed cavity formed by the lower fixed press lower mold core (14) with multiple air channels of the punching press, the press sliding mold frame (13) and the upper punching filter press mold core, and the slurry thickness of 35 mm required by the process is achieved. Then, the bottom of the lower press lower mold core (14) is fixedly adsorbed by the vacuum machine device to quickly dehydrate the slurry layer, and at the same time, the upper movable filter press of the punching press is pressed. The mold core squeezes the slurry layer downward, and performs progressive multi-stage downward high-pressure filtration under the condition of 0-35Mpa hydraulic cylinder oil pressure. The upper movable filter press mold core is adsorbed by vacuum negative pressure for rapid dehydration, and can be pressed into wet bricks with a moisture content of about 8-9%. The pressing frequency is 10 bricks per minute. Then the positive pressure water vapor blowing device is combined with the filter press mold core for demoulding. The lower filter press mold core is positively demoulded, and the upper filter press mold core and the sliding mold frame are raised for positive pressure demoulding. Then, it is directly moved to a conventional roller drying kiln through the mechanical arm suction cup, dried to a moisture content of 1.5-2.5%, and then fired at 1200℃.

Under pressure, multiple groups of multi-stage downward pressure vacuum filter plates (3-1) and multiple groups of filter rollers (17) are gradually pressed and dehydrated to form high-humidity bricks with a moisture content of about 17%. Then, multiple groups of filter rollers are pressed and dehydrated under 3-15 MPa hydraulic cylinder oil pressure, and high-frequency vibration is used for rapid dehydration. Further, high-pressure pressing and rapid wind blowing are carried out under 15-35 MPa hydraulic cylinder oil pressure to form dense bricks with a moisture content of about 9%. Then, under 35-0 MPa hydraulic cylinder oil pressure, high pressure is gradually released and further rapid wind blowing is carried out to dehydrate the filter belt, adhesive tape and bricks. Positive air pressure is forced to blow the demoulding device to separate the filter belt from the bricks and demould them. The pressing line speed is 10 meters per minute. The intact bricks are then synchronously cut and moved to a conventional roller drying kiln for drying and drying to a moisture content of 1.5-2.5%. Then, they are fired at 1200°C.
