Description

Technical Field

[0001] The invention relates to the technical field of ceramic drying, in particular to a microwave mesh belt uniform drying device for ceramic roller kiln slurry blanks. Background Art

[0002] For bathroom ceramic bodies with a moisture content of 20%, the traditional drying method is to pile the materials in a drying room and slowly dry them with hot air at low temperature. For example, a ceramic toilet takes a week to dry. The long drying time results in low yield, many cracks, and high energy consumption. Most ceramic tile production uses powder semi-dry pressing. The moisture content of dry pressed ceramic bodies is 7%. Hot air roller kiln drying is used, and the general cycle is one hour. The moisture content of the green body is 7%. On the one hand, the shrinkage is small due to the low moisture content. On the other hand, due to the gap between the rollers, the support point of the green body is constantly changing when it moves on the rollers, so that the drying stress can be released and the drying shrinkage can be carried out. After searching, it is found that the typical ceramic drying device in the prior art is a ceramic drying device with publication number CN109099655A, which includes a drying box body, a screw rod 2 is arranged inside the drying box body, three inclined plates are connected to the top of the screw rod 2, and a protrusion is connected to the side of the three inclined plates close to each other, and a support plate 3 is connected to the side wall of the drying box body. A motor is installed on the top of the support plate 3, and the output end of the motor passes through the side wall of the drying box body and extends to the drying box body. The screw rod 1 is connected, and the screw rod 1 is meshed with the screw rod 2. The ceramic drying device is provided with three inclined plates, the three inclined plates are inclined, and the side walls of the three inclined plates close to each other are provided with protrusions. Its main feature is that the ceramic is placed in the middle of the three inclined plates, and the ceramic side wall is clamped by the protrusion. Since the surface of the protrusion is smoothly arranged, the inclined plate is driven to rotate when the screw rod 2 rotates, and the ceramic does not move when the inclined plate rotates, thereby achieving the purpose of drying all surfaces of the ceramic thoroughly.

[0003] In summary, the existing roller kiln drying cannot be directly used because the green body has no strength when the moisture content is high, the green body is soft, and it will form wave deformation when moving on the stick. If the green body is dried on a pallet, shrinkage stress will be generated due to the inability to move between the green body and the pallet during the drying process (there is a shrinkage problem of about 2% during the drying process from 20% moisture to 10%), which will eventually lead to cracking. In view of the above problems, the existing equipment needs to be improved. Summary of the invention

[0004] The object of the present invention is to provide a microwave mesh belt uniform drying device for ceramic roller kiln mud blanks, so as to solve the problem of the existing roller kiln drying proposed in the above background technology, because the blank has no strength when the moisture content is high, the blank is soft, and it will form wave deformation when moving on the stick. The blank is dried with a support plate, which will cause shrinkage stress due to the inability to move between the blank and the support plate during the drying process, which eventually leads to cracking.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution: a microwave mesh belt uniform drying device for ceramic roller kiln slurry blanks,

[0027] Embodiment 1

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an air supply conveying mechanism 2 is installed on the base 1, and the air supply conveying mechanism 2 includes a motor 201, a conveying assembly 202, a belt transmission structure 203, a support seat 204, a chain transmission structure 205, a first transmission rod 206, a bevel gear transmission structure 207, a second transmission rod 208 and a fan blade assembly 209. The output end of the motor 201 is connected to the conveying assembly 202, and the conveying assembly 202 is connected through the belt transmission structure 203, the conveying assembly 202 is connected to the first transmission rod 206 through the chain transmission structure 205, and the first transmission rod 206 is connected to the second transmission rod 208 through the bevel gear transmission structure 207. At the same time, a fan blade assembly 209 is arranged on the second transmission rod 208, and the fan blade assembly 209 is arranged in three groups, and the fan blade assembly 209 is respectively arranged below one side of the first microwave heating assembly 3, the second microwave heating assembly 4 and the third microwave heating assembly 5.

[0029] In a further embodiment, the first microwave heating assembly 3 , the second microwave heating assembly 4 , and the third microwave heating assembly 5 are connected to the base 1 through a rack 6 , and an inspection door 13 is provided on a side of the base 1 .

[0030] In a further embodiment, a temperature and humidity sensor 7 is installed on the first microwave heating component 3, the second microwave heating component 4, and the third microwave heating component 5, and the temperature and humidity sensor 7 is electrically connected to the control box 8. At the same time, a far-infrared heating device 9 is arranged on one side of the third microwave heating component 5. The control box 8 is installed on the top of the first microwave heating component 3, the second microwave heating component 4, and the third microwave heating component 5, and a control panel is arranged on the control box 8. At the same time, the control box 8 is electrically connected to the far-infrared heating device 9.

[0031] In a further embodiment, the dehumidification fan 10 is arranged on the top of the first microwave heating component 3, and the dehumidification fan 10 is connected to the air collecting hood 12 through the conveying pipe 11, and the air collecting hood 12 is connected to a side wall of the frame 6.

[0032] Specifically, in the actual working process, the motor 201 drives the conveying assembly 202 to rotate and convey the embryo under the cooperation of the belt transmission structure 203, and the first microwave heating assembly 3 performs the first stage heating on the embryo moved thereunder. After the preliminary heating, the embryo continues to move rightward to the bottom of the second microwave heating assembly 4 under the conveyance of the conveying assembly 202, and the second microwave heating assembly 4 performs the second stage heating on it. After the heating, the embryo continues to move rightward to the bottom of the third microwave heating assembly 5 under the conveyance of the conveying assembly 202, and performs the third end heating to continue heating to dry it. After the three stages of heating, the far-infrared heating device 9 performs the final high-temperature drying operation on it.

[0033] On the other hand, when the conveying assembly 202 rotates, the chain transmission structure 205 drives the first transmission rod 206 to rotate, and the first transmission rod 206 drives the second transmission rod 208 to drive the fan blade assembly 209 to rotate through the bevel gear transmission structure 207. The fan blade assembly 209 conveys the waste heat generated during the drying process of the kiln tail, namely the third microwave heating assembly 5 and the far-infrared heating device 9, to the front, so that it passes through the second microwave heating assembly 4 and the first microwave heating assembly 3 in sequence, that is, the embryo body is auxiliary dried by hot air. At the same time, the dehumidification fan 10 extracts the hot and humid airflow moving to the surrounding area from the feed port, so that it is quickly discharged to the outside;

[0034] The first stage uses microwave low-temperature drying to dry the embryo from 20% to 16%, the temperature is controlled at 40-50 degrees, the hot air humidity is 60-70%, and the hot air uses the humid hot air of the last two stages. The embryo loses a small amount of moisture and solidifies, and enters the second stage of drying with a certain strength;

[0035] In the second stage, the moisture content is dried from 16% to 10%, and microwaves are used to dry the moisture content. The hot air temperature is 70-80 degrees and the humidity is 50-60%. At this time, the moisture drying speed of the embryo can be controlled by controlling the humidity of the hot air and the temperature inside and outside the embryo can be controlled by microwaves to ensure that the drying shrinkage is consistent, thereby increasing the drying speed and ensuring the quality of the dried embryo. Then the temperature is controlled at 70-80 degrees and the humidity is controlled at 50-60%, so that the moisture quickly reaches the surface of the embryo. Controlling the humidity of the hot air can further control the evaporation rate of the moisture, ensuring that the surface and internal water loss rates are consistent, and avoiding cracks caused by uneven drying.

[0036] In the third stage, the moisture content of the green body is dried from 10% to 0.3%. Before leaving the drying kiln, the green body is heated by a far-infrared heating device 9 to control the surface temperature of the green body at 80-130 degrees, thereby meeting the requirements of subsequent processes.

[0037] In summary, through microwave + hot air + electric heating far-infrared composite drying, the embryo with a moisture content of 20% can be quickly dried within one hour.

[0038] Embodiment 2

[0039] This embodiment is a further description of the above embodiment. It should be understood that this embodiment includes all the aforementioned technical features and is further described in detail.

[0040] like Figure 3 , Figure 5 and Figure 6As shown, in a further embodiment, the conveying assembly 202 includes a full roller conveying structure, a mesh belt support bar combined with a roller conveying structure, a mesh belt fluff combined with a roller conveying structure, an adhesive tape combined with a roller conveying structure and an air cushion combined with a roller conveying structure, a full roller conveying structure, a mesh belt support bar combined with a roller conveying structure, a mesh belt fluff combined with a roller conveying structure, an adhesive tape combined with a roller conveying structure and an air cushion combined with a roller conveying structure.

[0041] In a further embodiment, the full roller conveying structure is composed of three groups of roller conveying mechanisms, as shown in the attached Figure 3 As shown, the three groups of roller conveying mechanisms are connected by a belt transmission structure 203, and the three groups of roller conveying mechanisms are correspondingly arranged below the first microwave heating component 3, the second microwave heating component 4 and the third microwave heating component 5. At the same time, a support seat 204 is arranged below the rollers. The roller conveying mechanism uses thin rollers to reduce the roller spacing to prevent the blank from forming wave deformation due to the large roller spacing during the movement. Support seats 204 are used every 30-50 cm under the rollers to support the blanks to prevent the rollers from being unable to support the weight of the blanks and deforming during use. At the same time, microwave heating air drying is adopted. Hot air is blown into the lower part of the dryer, passes through the gaps between the sticks to the upper part of the dryer, and is extracted by the smoke exhaust fan to take away moisture.

[0042] In a further embodiment, the mesh belt support bar combined with the roller conveying structure is composed of a mesh belt with support bars on the surface and two sets of roller conveying mechanisms. The mesh belt with support bars on the surface and the two sets of roller conveying mechanisms are connected through a belt transmission structure 203, and the mesh belt with support bars on the surface is arranged below the first microwave heating component 3, and the two sets of roller conveying mechanisms are respectively arranged below the second microwave heating component 4 and the third microwave heating component 5, as shown in the attached Figure 5 As shown, there are several support bars on the mesh belt, the support bar width is 2 mm, and the support bars are arranged one high and one low like gear teeth. The high support bar is a fixed support bar, and the low support bar can be raised and lowered to be a movable support bar. There is a shrinkable liquid bar under the movable support bar. When the liquid is pressurized, the movable support bar can be raised 4 mm upward, and when the liquid is depressurized, the movable support bar can be lowered 4 mm. The movable support bar is 2 mm lower than the fixed support bar when it is at a low position, and 2 mm higher than the fixed support bar when it is at a high position. When the equipment is running, the movable support bar forms a lifting movement through liquid pressurization and depressurization. By controlling the time and speed of pressurization and depressurization, the movable support bar and the fixed support bar can be controlled to alternately support the embryo. For example, after the liquid bar is pressurized by the pressurizing device, the movable support bar rises 2 mm higher than the fixed support bar. After two seconds, the liquid bar is depressurized and lowered, and is 2 mm lower than the fixed support bar. After another two seconds, the liquid bar is pressurized and rises. In this rise and fall, the shrinkage stress of the embryo is released, and the shrinkage is completed by gradual water loss to avoid cracks. The mesh belt and support bar are made of wave-transparent materials that do not absorb microwaves.

[0043] In a further embodiment, the mesh belt fluff combined with roller conveying structure is composed of a mesh belt with a cylinder on the surface and two sets of roller conveying mechanisms, the mesh belt with a cylinder on the surface and the two sets of roller conveying mechanisms are connected through a belt transmission structure 203, and the mesh belt with a cylinder on the surface is arranged below the first microwave heating component 3, and the two sets of roller conveying mechanisms are respectively arranged below the second microwave heating component 4 and the third microwave heating component 5, as shown in the attached Figure 6 As shown, there are many small cylinders on the grid belt. The head of the cylinder is a smooth spherical shape. The straight part of the cylinder is elastic and can swing left and right. The embryo is placed flat on the belt and supported by many cylinders. The gaps between the cylinders can exhaust steam. When the embryo shrinks during the drying process, the cylinder can swing to produce displacement to eliminate the stress of the embryo. After moving, the cylinder returns to its original position.

[0044] In a further embodiment, the rubber belt combined with the roller conveying structure is composed of a grid belt with a rubber blanket on the surface and two groups of roller conveying mechanisms. The grid belt with the rubber blanket on the surface and the two groups of roller conveying mechanisms are connected through a belt transmission structure 203, and the grid belt with the rubber blanket on the surface is arranged below the first microwave heating component 3, and the two groups of roller conveying mechanisms are respectively arranged below the second microwave heating component 4 and the third microwave heating component 5. The belt is made of non-absorbent material, and there are small holes on the belt for drainage. The belt has curved lines stacked together to form an elastic layer, which is similar to the existing rubber blanket. It is a non-absorbent material. When the embryo is on the elastic layer and is dried and shrunk, the curved lines can slide between each other, providing displacement space for the embryo to shrink and offset the shrinkage stress. When the embryo shrinks and moves, the curved lines return to their original positions due to their own elasticity and carry the second embryo for drying.

[0045] In a further embodiment, an air cushion combined with roller conveying structure is composed of a roller conveying mechanism and a grid belt with an air cushion on the surface, and the grid belt with an air cushion on the surface is arranged below the first microwave heating component 3, and two groups of roller conveying mechanisms are respectively arranged below the second microwave heating component 4 and the third microwave heating component 5, an air layer is formed between the embryo and the belt, the belt is inclined forward, the embryo slides forward, the gas uses low-temperature moisture, and the embryo is dried using microwaves + low-temperature moisture during sliding. After the first stage of drying the embryo has strength, it enters the second stage. There are dense and uniform small holes on the transport belt, and the small holes are in the shape of inclined holes, inclined in the direction of embryo movement, gas bulges out from the belt, an air cushion is formed between the belt and the embryo, and the belt is inclined in the direction of embryo movement.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
