A drying equipment for processing ceramic fiber sealing gaskets

Abstract

This utility model discloses a drying device for processing ceramic fiber sealing gaskets, applied in the field of ceramic fiber sealing gasket drying technology. It utilizes an arched frame and rollers to support the gasket during drying. When the gasket is relatively wet and heavy, it simultaneously contacts the dispersed rollers and the top of the arched frame, at which point the spring is compressed. As drying progresses and the gasket becomes lighter, the spring rebounds, and the arched frame gradually rises to a position level with or slightly lower than the rollers. The elastic coefficient of the spring is positively correlated with the moisture content within the supported gasket. That is, through the compression and rebound of the spring, the height of the arched frame can automatically and dynamically adjust the supporting force and position according to the actual weight of the gasket, without external intervention. This ingenious and reliable structure saves the cost of installing transmission rollers.

Description

Technical Field

[0001] This utility model relates to the field of ceramic fiber sealing gasket drying technology, specifically a drying equipment for processing ceramic fiber sealing gaskets. Background Technology

[0002] Ceramic fiber sealing gaskets are flexible sealing materials made from inorganic ceramic fibers using a special process. After the gasket is formed using a wet process, it needs to be dried to reduce the probability of surface cracking and bulging caused by moisture vaporization during high-temperature use.

[0003] Existing methods typically involve deploying multiple sets of conveyor rollers within the drying plant area. A liner is laid on top of these rollers, and a drive mechanism controls the rollers to rotate synchronously, moving the liner within the conveyor zone. Hot air is blown out by the drying equipment to heat and dry the liner. Once the liner has finished moving within the conveyor zone, the drying process is almost complete. The drying efficiency depends on the speed at which the liner moves within the conveyor zone and the magnitude of the heat radiation.

[0004] The density of the conveyor rollers mentioned above affects the cost of the production line setup and the drying quality of the liner. A larger number of rollers provides better support for the liner, but it is more expensive and affects the drying quality of the area where the liner and rollers contact. A smaller number of rollers is cheaper, but it provides less support for the liner, causing the liner to sag between the rollers and affecting the flatness of the liner after drying. Summary of the Invention

[0005] The purpose of this invention is to provide a drying device for processing ceramic fiber sealing gaskets, thereby overcoming the aforementioned shortcomings of the prior art. To achieve the above objective, this invention provides the following technical solution: A drying device for processing ceramic fiber sealing gaskets, positioned within the heat radiation range used for drying, comprising: a conveyor wheel, including a support and rollers rotatably connected to the support, wherein several rollers rotate synchronously under the control of a power component; an anti-sagging component, including a bottom ring, a spring, and a top ring, wherein the bottom ring is mounted on the support, and the top ring and bottom ring are elastically connected by a spring, the top ring being able to slide up and down along the axial direction of the support, and the elastic coefficient of the spring being positively correlated with the moisture content within the supported gasket; and an arch frame, connecting two adjacent top rings for supporting the gasket.

[0006] Preferably, a limiting rod is fixed on the bottom ring, and the limiting rod is located on the downward movement path of the top ring.

[0007] Preferably, the bracket has a neck with a gradually changing diameter, the neck including a large end and a small end, the inner wall diameter of the top ring is smaller than the diameter of the large end but larger than the diameter of the small end, and the bottom ring is installed on the lower side of the large end.

[0008] Preferably, the bracket has an upward-facing stepped surface, and the bottom surface of the bottom ring is fitted onto the stepped surface.

[0009] Preferably, the clamp includes two half-clamps, each half-clamp having a through hole at both ends, and a threaded fastener for locking the two half-clamps is inserted through the through hole.

[0010] Preferably, the power component includes a belt drive system and a drive shaft, which are fixedly connected between rollers in the same row and the same drive shaft, and adjacent drive shafts are driven by the belt drive system.

[0011] Preferably, the roller is rotatably connected to the end cap, and the end cap and the top of the bracket are detachably connected by a threaded structure.

[0012] The beneficial effects of this invention are as follows: The drying process utilizes both an arch frame and rollers to support the liner. When the liner is relatively wet and heavy, it simultaneously contacts the dispersed rollers and the top of the arch frame, at which point the springs are compressed. As drying progresses and the liner becomes lighter, the springs rebound, and the arch frame gradually rises to a position level with or slightly lower than the rollers. In other words, through the compression and rebound of the springs, the height of the arch frame can automatically and dynamically adjust the support force and position according to the actual weight of the liner, without external intervention. This ingenious and reliable structure saves the cost of installing drive rollers. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This product must be used in conjunction with a device that has drying capabilities. The drying equipment can be a hot air dryer or an electric heating dryer. These devices transfer heat radiation to the moving pad, heating and drying it.

[0023] like Figures 1-5 This product comprises several main components, including a conveyor wheel 10, an anti-sagging component 20, and an arch frame 30. The conveyor wheel 10 is an improvement on the existing conveyor wheel structure. Combined with the anti-sagging component 20 and the arch frame 30, it increases the amount of heat radiation to the pad while ensuring sufficient support.

[0024] Example 1

[0025] The transmission wheel 10 includes a bracket 11, an end cap 12, and rollers 13. The bracket 11 is fixed to a metal frame supporting the entire product. The end cap 12 is threadedly connected to the upper part of the bracket 11, and a corresponding roller 13 is rotatably connected to the end cap 12. Several rollers 13 in the same row are all fixedly connected to the same transmission shaft. The power component drives the transmission shaft to rotate, thereby driving the corresponding rollers 13 in the same row to rotate. Several transmission shafts can rotate synchronously through a belt drive system. The simplest belt drive system includes several pulleys and a belt. Each transmission shaft is fixed to a corresponding pulley, and the belt is simultaneously fitted onto all pulleys. One pulley is fixedly connected to the output shaft of a motor. The motor is connected in series with the mains power. After the power is turned on, the motor drives several transmission shafts to rotate synchronously through the belt drive system. The above belt drive system is only an example. Since belt drive systems are existing technology, the version and structure of the belt drive system are not limited in actual use.

[0026] In the first embodiment, the anti-sagging component 20 includes a bottom ring 21, a limiting rod 22, and a top ring 23. The bottom ring 21 is mounted on the bracket 11, and the limiting rod 22 is fixed to the bottom ring 21, extending upward along the Z-axis. The top ring 23 and the bottom ring 21 are connected by a spring. The inner walls of both the bottom ring 21 and the top ring 23 are fitted with the outer wall of the bracket 11 to improve assembly convenience and stability during use. When supporting the pad, the top ring 23 moves downward against the elastic force, and the top ring 23 will touch the limiting rod 22. The presence of the limiting rod 22 can limit the excessive downward movement of the top ring 23.

[0027] In the second embodiment, the support 11 is a cylindrical structure with a curved neck. The neck includes a large end and a small end, with the small end facing upwards and the large end facing downwards. The bottom ring 21 is installed on the lower side of the large end of the support 11. The anti-sagging component 20 includes the bottom ring 21, the top ring 23, and a spring. The inner diameter of the top ring 23 is smaller than the diameter of the large end of the support 11 but larger than the diameter of the small end. Therefore, as the top ring 23 moves downwards against the elastic force, it will be stuck at the gradually changing neck position of the support 11, thereby limiting the excessive downward movement of the top ring 23.

[0028] Example 2

[0029] Based on the first or second scheme in Embodiment 1, Embodiment 2 has the following scheme;

[0030] In the first embodiment of Example 2, the support 11 is a stepped column structure with an upward-facing stepped surface. After the bottom ring 21 passes through the upper end of the support 11, the bottom surface of the bottom ring 21 is engaged with the stepped surface, thereby limiting the position of the bottom ring 21.

[0031] In the second embodiment of Example 2, the lower side of the large end of the bracket 11 is a complete column structure without a stepped surface. The clamp 40 includes two half-clamps, which are fastened together by bolts and nuts. After the two half-clamps are placed on the outside of the bracket 11, the half-clamps are locked onto the bracket 11 using bolts and nuts. Then, the bottom ring 21 passes through the upper end of the bracket 11, and the bottom surface of the bottom ring 21 is located on the upper end surface of the clamp 40, thereby limiting the position of the bottom ring 21.

[0032] Furthermore, magnets are attached to the bottom ring 21, and magnets are also attached to the stepped surface or the upper surface of the clamp. The two magnets attract each other, which can improve the stability of the bottom ring 21.

[0033] Based on Embodiments 1 and 2, each support 11 is fitted with an anti-sagging element 20, and adjacent anti-sagging elements 20 are connected by an arch frame 30. The middle of the arch frame 30 arches upward to support the padding.

[0034] Preferably, the arch frame 30 is formed by bending a sheet metal, and the width of the plane where the arch frame 30 and the pad contact is less than the thickness of the roller 13.

[0035] Preferably, the arch frame 30 is formed by bending a bar. In this case, the contact position between the arch frame 30 and the liner is the generatrix of the arch frame 30, resulting in a smaller contact area, which is more conducive to drying.

[0036] During use, the padding is supported by the arch frame 30 while in contact with the relatively dispersed rollers 13. At this time, the spring between the bottom ring 21 and the top ring 23 is compressed to a greater degree, and the highest point of the arch frame 30 is lower than the highest surface of the rollers 13, which can prevent the padding part between the rollers 13 from sagging too much. As drying proceeds, the moisture in the padding gradually evaporates, and the weight of the padding decreases. At this time, the spring compression decreases, and the highest point of the arch frame 30 gradually moves up to a position that is level with or slightly lower than the highest surface of the rollers 13. After the padding is removed from the corresponding arch frame 30, the arch frame 30 is higher than the highest surface of the rollers 13 when unloaded.

[0037] It should be noted that the weight of the padding changes gradually along a drying line. Therefore, the spring constants of the springs at different locations need to be selected appropriately to ensure the reliability of the support provided by the arch frame 30 to the padding. That is, the spring constants are larger closer to the start of the drying line and smaller closer to the end of the drying line.

[0038] like Figure 1 and Figure 3 When in use, the operator can select the placement and quantity of the arch frame 30 according to the placement of the roller 13 to ensure the reliability of the support for the pad.

[0039] Furthermore, the cost of this product is lower than that of installing conveyor rollers.

[0040] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
