Description

Technical Field

[0001] The invention relates to the technical field of ceramic body drying, and in particular to a multi-layer ceramic body microwave-assisted continuous drying line. Background Art

[0002] Energy consumption is an important issue in the traditional ceramic drying process. In the ceramic industry, traditional drying methods, such as hot air drying, have problems such as high scrap rate, long drying cycle, and high energy consumption. Microwave-assisted drying technology uses the basic principle of microwave heating and drying, that is, converting electromagnetic energy into heat energy through dielectric loss to achieve fast and uniform drying effect.

[0003] The principle of microwave heating and drying is to use microwave energy to penetrate the material, so that the water molecules inside the material rotate violently under the action of the electromagnetic field, thereby generating friction heat to achieve drying. This drying method not only improves the drying speed, but also helps to improve the quality of ceramic products. However, the penetration ability of microwaves decreases with the increase of the thickness of the ceramic body. For a certain thickness of the body, microwaves can penetrate, but if the body is too thick or the number of stacked layers is too large, the penetration ability of microwaves will be significantly reduced, resulting in uneven drying between the bodies. If batch drying is considered, the production efficiency will be greatly reduced. Summary of the invention

The inner wall of the hollow shaft 22 is slidably connected with a round block 221, and the end surface of the round block 221 is fixedly connected with a slide plate 222 that slides with the inner wall of the slide plate 273 through a straight rod.

[0028] refer to Figure 1-Figure 9 In the traditional ceramic drying process, energy consumption is an important issue. In the ceramic industry, traditional drying methods, such as hot air drying, have problems such as high scrap rate, long drying cycle, and high energy consumption. If microwave-assisted drying technology is used, the drying cycle can be shortened and energy consumption can be reduced. However, the microwave penetration ability decreases with the increase of the thickness of the ceramic body. For a body of a certain thickness, microwaves can penetrate, but if the body is too thick or the number of stacked layers is too large, the microwave penetration ability will be significantly reduced, resulting in uneven drying between the bodies. If batch drying is considered, the production efficiency will be greatly reduced. In order to overcome the above-mentioned defects, the present invention designs a multi-layer ceramic body microwave-assisted continuous drying line.

[0029] Ceramic body placement: The present invention can synchronously dry a large number of ceramic blanks, so a large number of ceramics can be picked up manually, by a robot or by automated equipment, and the ceramic blanks to be dried are placed on the loading tray 25 of the loading part 2, and then the external driving unit drives the placement frame 13 to rotate slowly around the inside of the frame 12. During the slow rotation, under the gravity of the counterweight 26, the loading tray 25 is always oriented upward (relative to the loading rack 21, the upper surface of the loading tray 25 is always kept in a constant horizontal state), so as to avoid shaking and damage of the ceramic blanks to be dried, and finally the placement frame 13 is in a tilted state, and at the same time, rows of ceramic blanks are "arranged in a stepped manner", and the highest point of the ceramic blanks in the previous row is slightly lower than the lowest point of the ceramic blanks in the next row.

[0030] Drying of ceramic bodies: From the above, it can be seen that the rows of ceramic green bodies are "arranged in a stepped manner", and the height difference between the highest point and the lowest point of the ceramic green bodies is slightly smaller than the microwave irradiation area of ​​the microwave generator 3. Therefore, when the microwave generator 3 synchronously dries batches of ceramic green bodies, the ceramic green bodies do not interfere with each other, avoiding the ceramic green bodies from overlapping each other, which would lead to a significant decrease in the penetration ability of microwaves and uneven drying between the green bodies.

[0031] Ceramic body multi-faceted rotation switching: As can be seen from the above, the ceramic blank is always in a stationary state relative to the carrier plate 25, so after the "regional arc surface" of the ceramic blank close to the microwave generator 3 is dried, it needs to be rotated at a small angle and switched to the "other regional arc surface", and the small angle rotation and microwave-assisted drying are repeated until the ceramic blank is dried, thereby achieving a fast and uniform drying effect. Specifically, the core of the present invention is "using bidirectional reciprocating rotation to achieve unidirectional small angle rotation switching of the ceramic blank (bidirectional microwave)".

[0032] Counterclockwise rotation toggle: Taking the left half of the placement frame 13 as an example, when the placement frame 13 rotates counterclockwise, it drives the pushing member 27 on the loading part 2 to continuously approach the side of the arc plate 111 until the smooth wheel 279 on the pushing member 27 contacts the arc plate 111, and the arc plate 111 begins to generate a certain thrust on the smooth wheel 279, and the thrust gradually increases (in the initial state, since the elastic force of the second return spring 277 is greater than the elastic force of the first return spring 275, the second smooth plate 276 pushes the second tooth plate 272 to engage tightly with the tooth groove 231 of the rotating seat 23. At the same time, the first tooth plate 271, the second tooth plate 272 and the slide plate 273 are a whole. When the second tooth plate 272 engages with the tooth groove 231, the first tooth plate 271 and the tooth groove 231 are separated from each other, and only one of the two is engaged with the tooth groove 231). Under the pushing force of the arc plate 111 (the front arc surface of the arc plate 111 gradually increases the thrust of the smooth wheel 279, and the rear arc surface of the arc plate 111 keeps the thrust of the smooth wheel 279 constant), the smooth wheel 279, the reciprocating frame 278, the first smooth plate 274, the first tooth plate 271, the second tooth plate 272 and the slide plate 273 are driven to undergo a short-distance displacement in the cavity 211, the first return spring 275 is stretched, and the second smooth plate 276 is compressed, the first tooth plate 271 is tightly meshed with the tooth groove 231, and the second tooth plate 272 is separated from the tooth groove 231, thereby realizing the meshing switching of the first tooth plate 271 and the second tooth plate 272.

[0033] Until the carrier 21 contacts the support seat under the arc plate 111 and stops rotating, at the same time, the magnetic plate 224 slowly rotates to the vicinity of the end face of the magnetic block 112, at which time the magnetic block 112 generates an outward magnetic thrust on the magnetic plate 224, driving the round block 221 to slide a short distance along the inner wall of the hollow shaft 22, driving the slide plate 222, the first tooth plate 271, the second tooth plate 272 and the slide plate 273 to slide a short distance synchronously, and the strong spring 223 undergoes elastic deformation (installed at both ends of the slide plate 273), and the first tooth plate 271 drives the rotating seat 23, the adjustment frame 24, the carrier plate 25 and the ceramic blank to rotate clockwise at a small angle synchronously, so that the batch of ceramic blanks can be synchronously switched to the "arc surface of another area", and the microwave generator 3 is cooperated to realize the drying of the "arc surface of another area".

[0034] Clockwise rotation to switch: It is worth mentioning that a tooth seat 232 is further provided under the rotating seat 23 of the present invention. When the rotating seat 23 rotates clockwise at a small angle, the teeth on the tooth seat 232 are driven to push the clamping block 214 inward to compress the elastic plate 213 in turn. After the rotation stops, under the elastic force of the elastic plate 213, the clamping block 214 is driven to reset and clamp into the teeth on the tooth seat 232 again to prevent the tooth seat 232 from rotating in the opposite direction. When the placement frame 13 rotates clockwise, the magnetic plate 224 is driven to preferentially detach from the end surface of the magnetic block 112 (the first tooth plate 271 is still in meshing state with the tooth groove 231). Under the action of the block 214, the strong spring 223 cannot drive the first tooth plate 271, the second tooth plate 272 and the slide plate 273 to reset preferentially until the smooth wheel 279 completely detaches from the arc plate 111 (completed instantly). Under the strong action of the second reset spring 277, the second tooth plate 272 is driven to mesh with the tooth groove 231 again, and the first tooth plate 271 is separated from the tooth groove 231. At the same time, the strong spring 223 drives the first tooth plate 271, the second tooth plate 272 and the slide plate 273 to gradually return to their original positions, and the second tooth plate 272 drives the rotating seat 23, the adjusting frame 24, the loading plate 25 and the ceramic blank to rotate clockwise at a small angle again (basically consistent with the arc surface switching range of counterclockwise rotation), so that the batch of ceramic blanks can be synchronously switched to "another area arc surface" again, and the above rotation operation is repeated. In combination with the microwave generator 3, the batch of ceramic blanks can be dried quickly and evenly.

[0035] In summary, the present invention adopts the placement frame 13 and the object-carrying part 2 to cooperate with each other, and has the following core functions: First, the placement frame 13 rotates slowly around the inside of the frame 12. Under the gravity of the counterweight 26, the direction of the loading plate 25 is always upward to prevent the ceramic blanks to be dried from shaking and being damaged. Finally, the placement frame 13 is in a tilted state, and rows of ceramic blanks are "arranged in a stepped manner". The ceramic blanks do not interfere with each other, avoiding the ceramic blanks from overlapping each other and affecting the microwave drying of the microwave generator 3.

[0036] Secondly, for ceramic blanks of different heights, in order to avoid mutual obstruction between the front and rear rows of ceramic blanks, the present invention can also adjust the placement height of the ceramic blanks. By using an external screwdriver to rotate the toothed ring 244 on the adjustment frame 24, the threaded sleeve 242 is driven to rotate up and down around the threaded rod 241, thereby adjusting the placement height of the ceramic blanks.

[0037] Thirdly, the core of the present invention is "using bidirectional reciprocating rotation to realize unidirectional small-angle rotation switching of ceramic green bodies, and cooperating with bidirectional microwave generator 3 for drying". In the process of "arranging rows of ceramic green bodies in a step-like manner", batches of ceramic green bodies can be synchronously rotated at small angles, eliminating the trouble of manual rotation one by one, and the angle of each rotation is consistent with high precision.

[0038] Fourthly, firstly, the switching between counterclockwise rotation and clockwise rotation can realize the switching of the "drying arc surface" of the ceramic body only by simple arrangement and rotation; secondly, the switching range of the "drying arc surface" is basically constant with high precision; thirdly, the ceramic body always rotates clockwise to dry the arc surface of the ceramic body in turn.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
