Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, and in particular to a secondary drying device. Background Technology

[0002] Secondary drying is a crucial step in the ceramic production process. After the initial drying and shaping of the ceramic blank, most of the surface moisture has evaporated, but a small amount of bound water remains inside. Secondary drying is primarily used to further reduce the moisture content of the blank. Through slow and uniform drying, it reduces the temperature and humidity gradients between the inside and outside of the blank, avoiding stress concentration that could lead to cracks or deformation. This ensures that the blank reaches an extremely low moisture content before high-temperature sintering, preventing rapid vaporization of moisture during firing and thus preventing cracking and allowing the sintering process to proceed smoothly.

[0003] Among common secondary drying equipment, tunnel drying kilns can achieve continuous production with high efficiency, requiring a chain conveyor mechanism to move the ceramic materials. To save space and ensure drying effect, the movement path of the ceramic materials is extended as much as possible within the drying space. In existing drying equipment, the chain conveyor mechanism has a relatively complex structure. The chain is long in the straight direction, making it prone to deformation and swaying. Furthermore, the chain needs to make multiple turns, during which it experiences significant tension. Therefore, the requirements for the chain are very high, resulting in a high failure rate and high equipment and maintenance costs. Utility Model Content

[0032] Reference Figures 1 to 5 The secondary drying equipment of this utility model is described in the following embodiments:

[0033] A secondary drying device includes a conveying device 100 and a drying device 200.

[0034] The conveying device 100 includes: a material support 110, a conveying drive mechanism 120, and a guiding mechanism 130. The material support 110 is used to hold and support incoming ceramic materials that require drying. The conveying drive mechanism 120 is used to move the material support 110. The conveying drive mechanism 120 includes a drive chain 124, which moves cyclically along a closed-loop path. There are multiple material support components 110, which are arranged along the closed-loop path and all connected to the drive chain 124.

[0035] The material support 110 has a guide portion 111. The guiding mechanism 130 has a guide slide. The guide slide extends along at least one segment of the closed-loop path. When the material support 110 is within the guide segment, the guide portion 111 is connected to the guide slide.

[0036] The drying device 200 has a drying space, and the closed-loop path is located within the drying space.

[0037] In practical use, the conveying drive mechanism 120 drives the material support 110 to move along a closed-loop path via the drive chain 124, thereby enabling the product supported on the material support 110 to be conveyed and moved within the drying space, thus achieving drying and dehydration. When the material support 110 is in the guide section, the guide slide can provide guidance or support to the guide section 111, thereby preventing the drive chain 124 from swaying or sagging, improving the conveying stability of the material support 110, and greatly reducing the strength requirements and cost of the drive chain 124.

[0038] To achieve force balance and improve stability, in this embodiment, the material support 110 is provided with guide portions 111 at both its left and right ends. The guide mechanisms 130 are arranged in pairs, with the material support 110 positioned between the two guide mechanisms 130. The guide portions 111 are connected to the guide tracks of the two guide mechanisms 130 on the left and right sides, respectively. The paired guide mechanisms 130 provide support and guidance to both the left and right ends of the material support 110.

[0039] The conveying drive mechanism 120 includes a drive motor 121 and a drive sprocket 122. A drive chain 124 is wound around the drive sprocket 122, and the drive motor 121 drives the drive sprocket 122 to rotate. When the drive motor 121 drives the drive sprocket 122 to rotate, the drive chain 124 moves through the meshing transmission between the drive sprocket 122 and the drive chain 124, thereby synchronously driving the movement of multiple material support components 110 to achieve material conveying.

[0040] The material support 110 is provided with drive sprockets 122 and drive chains 124 on both the left and right sides. The left and right ends of the material support 110 are respectively fixedly connected by two drive chains 124 arranged on the left and right sides, so that the material support 110 can maintain horizontal conveying.

[0041] In this embodiment, the material support 110 is a rectangular thin plate. The upper side of the material support 110 has a supporting surface with multiple contour grooves. The shape of the contour grooves is designed according to the shape of the ceramic material. In actual use, the left and right drive sprockets 122 rotate synchronously, causing the two drive chains 124 to move synchronously, thereby allowing the material support 110 to translate along a closed-loop path.

[0042] In the left-right projection, the two drive sprockets 122 on the left and right sides are staggered in the front-back direction, and the two drive chains 124 on the left and right sides are also staggered in the front-back direction. The left and right ends of the material support 110 are respectively provided with a front connecting part 112 and a rear connecting part 113, and the front connecting part 112 and the rear connecting part 113 are fixedly connected to the left and right two drive chains 124 respectively.

[0043] In this embodiment, the two guide portions 111 are respectively disposed at the middle of the left and right ends of the material support member 110. In a left-right projection, the two guide portions 111 of the material support member 110 overlap. The front connecting portion 112 is spaced apart on the front side of one of the guide portions 111, and the rear connecting portion 113 is spaced apart on the rear side of the other guide portion 111.

[0044] The front connecting part 112 and the rear connecting part 113 are respectively provided at the left and right ends of the material support 110. It is worth noting that the sum of the distance between the front connecting part 112 and the guide part 111 on the same side in the front-back direction and the distance between the rear connecting part 113 and the guide part 111 on the same side in the front-back direction is equal to the front-back offset distance of the two drive sprockets 122 or the two drive chains 124.

[0045] That is, during the conveying process of the material support 110 in the guide section, the two guide parts 111 are symmetrical from left to right and connected to the two guide mechanisms 130 on the left and right respectively, and the front connecting part 112 and the rear connecting part 113 are fixedly connected to the drive chains 124 that are staggered on the left and right sides respectively.

[0046] To achieve synchronous driving of the two drive chains 124, the conveying drive mechanism 120 further includes a drive shaft extending in the left-right direction. One end of the drive shaft is coaxially and fixedly connected to one of the drive sprockets 122 on one side, and the other end of the drive shaft is eccentrically connected to the other drive sprocket 122 via a transmission method such as belt drive, chain drive, gear drive, or worm gear drive. The output shaft of the drive motor 121 is driven by the drive shaft. The drive motor 121 drives the drive shaft to rotate, which synchronously drives the two drive sprockets 122 with their rotation axes offset from each other, thereby causing the two drive chains 124 to move synchronously.

[0047] In other embodiments, both ends of the drive shaft are eccentrically disposed with drive sprockets 122 located on the left and right sides, and the drive shaft and drive sprockets 122 are connected by transmission methods such as belt drive, chain drive, gear drive or worm gear drive.

[0048] To reduce the frictional resistance between the guide part 111 and the guide slide, the guide part 111 is rotatably provided with a guide roller, the rotation axis of the guide roller extends in the left and right direction, and the guide roller rolls against the guide slide.

[0049] In this embodiment, the guide section includes a translational section extending forward and backward, and the guide mechanism 130 includes a support strip 131 extending in the forward and backward direction. The guide portion 111 rolls against the upper side of the support strip 131. During the movement of the material support 110 within the translational section, the support strip 131 can provide support and guidance for the guide roller.

[0050] To ensure the ceramic material remains in the drying space for a sufficient time, the conveying drive mechanism 120 needs to provide a sufficient moving distance. In this embodiment, there are multiple translation segments, which are arranged at intervals along the vertical direction. One end of each translation segment connects to the end of an adjacent translation segment along an arc path, forming a serpentine moving path. This allows the material support 110 to move sequentially along each translation segment for conveying. The guiding mechanism 130 also includes a guide plate 132, which has a guide groove 133 extending in a semi-circular arc shape. The diameter of the semi-circular extension path of the guide groove 133 is consistent with the spacing between two adjacent support bars 131, so that both ends of the guide groove 133 are flush with the two adjacent translation segments. The guiding part 111 can move along the guide groove 133 from one translation segment to another.

[0051] In order to make the movement path of the drive chain 124 correspond to the shape of the guide section, the conveying drive mechanism 120 also includes a plurality of driven sprockets 123, which enable the drive chain 124 to bypass the semi-circular path and match the shape of the guide groove 133.

[0052] The drying device 200 is provided with a heat-insulating outer shell, which encloses the drying space. In this embodiment, the heat-insulating outer shell includes an outer frame and a housing. The outer frame is a frame structure, and the housing is a multi-layered composite structure. The housing is fitted onto the outer frame to enclose the drying space. In other embodiments, the heat-insulating outer shell may also employ an existing drying equipment housing structure, which will not be illustrated here.

[0053] The drying device 200 includes a hot air component 210 and an air duct component 220. The hot air component 210 is connected to the drying space through the air duct component 220. The hot air component 210 includes a combustion chamber 211, a main fan 212, and a circulating fan 213. Both the main fan 212 and the circulating fan 213 are connected to the combustion chamber 211. The air duct component 220 includes a heating main air duct 221, a circulating main air duct 222, and a circulating negative pressure pipe 223. One end of the heating main air duct 221 is connected to the main fan 212, and the other end extends into the drying space. Both the circulating main air duct 222 and the circulating negative pressure pipe 223 are connected to the circulating fan 213 and the drying space.

[0054] In actual use, the combustion chamber 211 increases the air temperature, and the main fan 212 can transport hot air through the heating main air duct 221 to the drying space to dry and dehydrate the ceramic materials. The circulating fan 213 sends hot air into the drying space along the circulating main air duct 222 and out through the circulating negative pressure pipe 223, so that the hot air in the drying space can flow and form a circulation, avoiding uneven heating or local overheating.
