Description

Technical Field

[0001] This utility model relates to the field of ceramic green body drying technology, specifically to a multi-layer ceramic green body microwave-assisted continuous drying line. Background Technology

[0002] Drying is a crucial step in ceramic production, and a significant portion of quality defects in ceramic products are caused by improper drying. The drying process in the ceramic industry has evolved from natural drying and chamber drying to the current continuous dryers, far-infrared dryers, solar dryers, and microwave drying technologies utilizing various heat sources.

[0003] Microwave drying involves irradiating a wet green body with microwaves. The direction and magnitude of the electromagnetic field change periodically over time, causing the polar water molecules within the green body to rotate violently due to the alternating high-frequency electric field. This friction converts the water molecules into heat energy, achieving the goal of uniformly heating and drying the entire green body.

[0004] However, microwave penetration weakens with increasing ceramic green body thickness. For a green body of a certain thickness, microwaves can penetrate, but if the green body is too thick or has too many stacked layers, the microwave penetration will significantly decrease, leading to uneven drying between green bodies. If batch drying is considered, production efficiency will be greatly reduced. Therefore, those skilled in the art provide a multi-layer ceramic green body microwave-assisted continuous drying line to solve the problems mentioned in the background art. Utility Model Content

The operating frame has a groove at its bottom, with the drive gear disk located inside the groove at its center. Multiple driven gear disks are arranged along the outer edge of the drive gear disk, meshing with each other. A through hole is located at the center of the operating frame, with the drive shaft inside. The drive shaft passes through the center of the drive gear disk and is fixedly connected.

A first motor is located at the end of the first motor drive shaft furthest from the drive shaft. The bottom of the first motor is fixedly positioned above the bottom wall of the base cavity. A connecting shaft is located above the drive shaft, passing through the upward extending end of the operating frame and connecting to the loading tray, which is fixedly connected to the connecting shaft. Toothed blocks are located at the edge of the operating frame.

[0008] After the first motor 302 is started, the ceramic blank rotates on its own axis. Then, the second motor 404 is started to make the entire supporting component 2 rotate. Through the cooperation of the first motor 302 and the second motor 404, the ceramic blank rotates on its own axis inside the equipment while also rotating as a whole. This allows the ceramic blank to be fully and evenly irradiated by microwaves, avoiding cracking caused by uneven heating and improving the product qualification rate.

[0009] As a preferred embodiment of the above technical solution, a rotating assembly is provided on the side of the cover; the rotating assembly includes a support frame, a second motor drive shaft, a transmission gear, and a second motor; the second motor is disposed above the bottom wall of the support frame, and a second motor drive shaft is disposed above the output shaft of the second motor, with the output shaft of the second motor fixedly connected to the second motor drive shaft; one end of the second motor drive shaft away from the output shaft of the second motor is disposed on the inner side wall above the support frame, and the second motor drive shaft is movably connected to the inner side wall above the support frame; a transmission gear is disposed on the side wall of the second motor drive shaft, and the spacing between the transmission gears is the same as the height of the bearing assembly; the transmission gear meshes with the edge teeth of the operating frame.

[0010] As a preferred embodiment of the above technical solution, each pair of the sequentially equidistantly arranged load-bearing components is provided with a box; the surface of each box is provided with a sealed door, one side of which is movably connected to one side of the box via a hinge; a door handle is provided on the sealed door away from the hinge, one end of which is movably connected to the sealed door via a rivet, and the other end of which is fastened to the surface of the box; multiple sets of slots are provided on the upper and lower side walls of the box, and rollers are provided inside the slots, which are fixed inside the slots by pins; the surface of the rollers contacts the operating frame; the side walls of the box are fixedly connected to the support frame; microwave generators are provided on both sides of the sealed door on the inner wall of the box;

After starting the first motor 302 and the second motor 404, the ceramic blank is rotated and rotated as a whole in the cavity, avoiding the influence of the distance limitation between the surface of the ceramic blank and the microwave generator 5, which would lead to uneven heating. The secondary rotation speeds up the heating and drying process and saves energy.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses multiple sets of supporting components to place ceramic blanks one on top of the other, so that the ceramic blanks do not interfere with each other and avoid overlapping of ceramic blanks, which would significantly reduce the microwave penetration ability and cause uneven drying between the blanks.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-3 As shown, this utility model provides a technical solution: a multi-layer microwave-assisted continuous drying line for ceramic blanks, including a cover 1. A support assembly 2 for supporting ceramic blanks is provided at the lower end of the cover 1. Multiple sets of support assemblies 2 are arranged in a equidistant array at the lower end of the cover 1, with the equidistant height space suitable for placing the ceramic blanks. A base 3 is provided at the lower end of each support assembly 2. The base 3 has a cavity inside, and the sidewall of the cavity edge is movably supported on the bottom of the support assembly 2. A box 6 is provided between each pair of the equidistantly arrayed support assemblies 2. A rotating assembly 4 is provided on the side of the cover 1. The rotating assembly 4 is used to adjust the internal space angle of the support assembly 2, facilitating the operator to pick up and place the ceramic blanks.

[0026] By placing ceramic blanks vertically in a confined space, and arranging the supporting components 2 vertically in sequence, more ceramic blanks can be placed in a more efficient manner, and energy can also be saved.

[0027] As one implementation method in this embodiment, please refer to Figures 3-5As shown, the supporting assembly 2 includes an operating frame 201, a driving gear disk 202, a driven gear disk 203, a drive shaft 204, and a loading tray 205. The operating frame 201 has a groove at its bottom, inside which the driving gear disk 202 is located. The driving gear disk 202 is positioned at the center of the groove. Multiple sets of driven gear disks 203 are arranged along the outer edge of the driving gear disk 202, and these driven gear disks 203 mesh with the driving gear disk 202 one by one. A through hole is provided at the center of the operating frame 201, inside which the drive shaft 204 is installed, and the drive shaft 204 passes through the hole. A drive gear disk 202 is centrally fixedly connected. A first motor drive shaft 301 is provided at the downward extension end of the drive shaft 204, and the drive shaft 204 is fixedly connected to the first motor drive shaft 301. A first motor 302 is provided at the end of the first motor drive shaft 301 away from the drive shaft 204. The bottom of the first motor 302 is fixedly installed above the bottom wall of the base 3 cavity. A connecting shaft is provided above the drive shaft 204. A loading tray 205 is provided at the upward extension end of the operating frame 201, and the loading tray 205 is fixedly connected to the connecting shaft. Toothed blocks are provided at the edge of the operating frame 201.

[0028] The first motor 302 is fixedly connected to the base 3. When the first motor 302 is started, it drives the drive shaft 204 to rotate through the first motor transmission shaft 301, causing the drive gear disk 202 fixed on the drive shaft 204 to rotate. Multiple sets of driven gear disks 203 mesh with the drive gear disk 202 and rotate together, so that the carrier disk 205 can rotate. In use, the ceramic blank is placed on the carrier disk 205 and rotates together with the carrier disk 205, so that the surface of the ceramic blank is irradiated by microwaves.

[0029] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a rotating assembly 4 is provided on the side of the cover 1; the rotating assembly 4 includes a support frame 401, a second motor drive shaft 402, a transmission gear 403, and a second motor 404; the second motor 404 is disposed above the bottom wall of the support frame 401, and the second motor drive shaft 402 is disposed above the output shaft of the second motor 404, and the output shaft of the second motor 404 is fixedly connected to the second motor drive shaft 402; one end of the second motor drive shaft 402 away from the output shaft of the second motor 404 is disposed on the inner side wall above the support frame 401, and the second motor drive shaft 402 is movably connected to the inner side wall above the support frame 401; a transmission gear 403 is disposed on the side wall of the second motor drive shaft 402, and the spacing of the transmission gear 403 is the same as the height of the bearing assembly 2; the transmission gear 403 meshes with the edge teeth of the operating frame 201;

[0030] After the first motor 302 is started, the ceramic blank rotates on its own axis. Then, the second motor 404 is started to make the entire supporting component 2 rotate. Through the cooperation of the first motor 302 and the second motor 404, the ceramic blank rotates on its own axis inside the equipment while also rotating as a whole. This allows the ceramic blank to be fully and evenly irradiated by microwaves, avoiding cracking caused by uneven heating and improving the product qualification rate.

[0031] As one implementation method in this embodiment, please refer to Figure 1 and Figures 6-7 As shown, the load-bearing components 2 arranged in a sequential, equidistant array are each paired with a housing 6. The housing 6 has a sealing door 101 on its surface, with one side of the sealing door 101 connected to one side of the housing 6 via a hinge. A door handle 102 is located on the sealing door 101 away from the hinge; one end of the door handle 102 is connected to the sealing door 101 via a rivet, and the other end of the door handle 102 is fastened to the surface of the housing 6. The upper and lower sidewalls of the housing 6 have multiple sets of slots, with rollers 601 inside each slot. The rollers 601 are fixed inside the slots by pins 602. The surface of the rollers 601 contacts the operating frame 201. The sidewalls of the housing 6 are fixedly connected to the support frame 401. Microwave generators 5 are arranged on both sides of the sealing door 101 on the inner wall of the housing 6. The microwave generator 5 includes a magnetron, a detection component, a control component, and water-cooling pipes.

[0032] The housing 6 is fixed by the support frame 401, and the microwave generator is fixed to the inner wall of the housing 6. After the first motor 302 and the second motor 404 are started, the ceramic blank is rotated and rotated as a whole in the cavity, avoiding the influence of the distance between the surface of the ceramic blank and the microwave generator 5, which would lead to uneven heating. In addition, the supporting component 2 is provided with multiple layers, and the multiple microwave generators 5 can be controlled separately, saving energy.

[0033] Working principle: After the first motor 302 is started, the drive shaft 204, drive gear disk 202, and driven gear disk 203 work together to cause the carrier disk 205 to rotate. The ceramic blank is placed on the carrier disk 205, and the rotation of the ceramic blank ensures that the side away from the microwave generator 5 can be radiated with uniform heat. After the second motor 404 is started, the support frame 401, the second motor drive shaft 402, and the drive gear 403 work together to cause the second motor drive shaft 402 to drive the drive gear 403, and the carrier assembly 2 meshing on the drive gear 403 rotates as a whole. This avoids uneven heating of the ceramic blank closer to the microwave generator 5 compared to the side farther away from the microwave generator 5. By setting up multiple layers of carrier assemblies 2, more space can be utilized for operation, and the multiple layers of carrier assemblies 2 can be controlled by the multiple microwave generators 5, saving energy. After the ceramic blank is finished, the ceramic blank needs to be removed. The second motor 404 is started to rotate the ceramic blank inside to the material handling port of the sealed door, so that the operator can easily pick up and put down the ceramic blank. The upper and lower side walls of the box 6 are equipped with rollers 601, and the surface of the rollers 601 is equipped with an operating frame 201. The rollers 601 play a role in supporting the operating frame 201 and stabilizing it.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
