Description

Technical Field

[0001] This utility model relates to the field of ceramic flat sheet film production technology, and in particular to a ceramic flat sheet film drying mechanism. Background Technology

[0002] After the sol-gel step, the film coated on the surface of the ceramic flat sheet membrane needs to undergo a drying step to remove solvents and some organic matter, forming a stable network structure. This prevents cracks from appearing in the ceramic flat sheet membrane, which would affect its high-temperature resistance, corrosion resistance, and resistance to microbial attack, thus extending its service life and reducing the frequency of replacement during use.

[0003] Because existing ceramic flat film preform drying equipment can dry multiple ceramic flat films at the same time, the drying degree of ceramic flat film preforms at different locations will be uneven within the same time period, which can easily cause some ceramic flat film preforms to develop cracks of varying degrees, resulting in significant losses. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a ceramic flat film drying mechanism to solve the problem of uneven drying of ceramic flat film preforms at different positions within the same time period.

[0005] To achieve the above objectives, this utility model provides a ceramic flat film drying mechanism, including a hot air blower disposed within a drying chamber and a support ring fixedly disposed within the drying chamber. The ceramic flat film drying mechanism further includes:

[0006] Rotate the support disc located inside the support ring.

[0007] Rotate the support shaft located at the bottom of the drying oven, the top of which is fixed to the bottom of the support plate.

[0008] A container is fixedly mounted on the top of the support plate, and the container is used to hold several ceramic flat film preforms to be dried.

[0009] A diffuser is slidably disposed between the heat blower and the container, the diffuser being used to direct the hot airflow to each ceramic flat film preform within the container.

[0010] Intermittent deflection section for driving the intermittent deflection of the support disk.

[0011] A reciprocating drive for driving the lateral reciprocating movement of the air diffuser and for driving the intermittent deflection section to operate.

[0012] Preferably, the air distribution unit includes an upper sliding seat and a lower sliding seat that are vertically slidably disposed within the drying chamber.

[0013] Several vertical partitions are arranged horizontally side by side between the upper slide and the lower slide.

[0014] A plurality of guide strips are disposed between two adjacent vertical partitions, and the two adjacent guide strips together form a drainage channel.

[0015] A return spring is fixedly installed between one of the inner walls of the drying oven and the sliding seat.

[0016] Preferably, the two opposing drainage channels are arranged in a figure-eight shape, and the two adjacent drainage channels enclose each other to form a funnel-shaped exhaust channel.

[0017] Preferably, the container includes a support frame fixedly disposed on the top of the support plate.

[0018] Several placement plates are vertically and fixedly arranged in the support frame. Several guide grooves are arranged in parallel along the longitudinal and transverse directions on the top of the placement plates. The several guide grooves are staggered and divide the top of the placement plates into several support blocks.

[0019] Preferably, the vertical cross-sectional shape of the guide channel is a trapezoid with a narrow top and a wide bottom, and the end face of the guide channel corresponds to the drainage channel.

[0020] Preferably, the intermittent deflection section includes four elastic elements circumferentially fixed on the support ring, a limiting block is fixedly provided at the free end of the elastic elements, a limiting groove is provided on the arc surface of the support plate, the limiting groove corresponds to the limiting block, a wedge-shaped lever is laterally fixed on the outside of the support shaft, a tension spring is fixed between the outside of the wedge-shaped lever and the bottom of the support plate, and a worm gear is fixedly sleeved on the outside of the support shaft.

[0021] Preferably, the free end of the wedge-shaped lever is an inclined surface, and the circumferential path of the inclined surface of the wedge-shaped lever covers the limiting groove.

[0022] Preferably, the reciprocating drive includes a rotating shaft rotatably disposed inside the drying chamber and a drive motor for driving the rotating shaft to rotate. A cam is fixedly sleeved on the outside of the rotating shaft, and the cam is used to push the container to move laterally reciprocally. A worm is provided at one end of the rotating shaft, and the worm meshes with the worm wheel.

[0023] The beneficial effects of this utility model are:

[0024] This invention features a diffuser that can move laterally in a straight line between the heat blower and the container. During this lateral movement, the diffuser distributes the high-speed, slightly warm airflow from the heat blower into multiple portions, guiding each portion to the top of the placement plate at different heights. This ensures the ceramic sheet film on the placement plate dries evenly. Furthermore, the crisscrossing guide channels on the placement plate and the intermittently 90° deflected support frame direct some of the slightly warm airflow to the bottom of the ceramic sheet film, ensuring even drying on both sides. This improves the drying uniformity of the ceramic sheet film at various locations and avoids the problem of significant differences in drying degree when multiple ceramic sheet films are dried simultaneously.

[0034] like Figures 1 to 4 As shown, a ceramic flat film drying mechanism includes a hot air blower 3 disposed inside a drying chamber and a support ring 1 fixedly disposed inside the drying chamber. The ceramic flat film drying mechanism also includes:

[0035] Rotate the support disc 8 located inside the support ring 1.

[0036] Rotate the support shaft 7 located at the bottom of the drying oven. The top of the support shaft 7 is fixed to the bottom of the support plate 8.

[0037] The holding component 2 is fixedly installed on the top of the support plate 8. The holding component 2 is used to hold several ceramic flat film preforms to be dried.

[0038] A diffuser 4 is slidably disposed between the heat blower 3 and the container 2. The diffuser 4 is used to guide the hot airflow to each ceramic flat film preform in the container 2.

[0039] Intermittent deflection section 6 is used to drive the intermittent deflection of support plate 8.

[0040] The reciprocating drive 5 is used to drive the air diffuser 4 to move laterally and to drive the intermittent deflection 6 to operate. In this way, when the container 2 deflects intermittently, the air diffuser 4 moves laterally in a straight line, so as to disperse the hot air blown out by the hot air blower 3 to various parts of the container 2, so as to dry several ceramic flat film preforms at the same time and avoid large differences in the degree of drying between several ceramic flat film preforms.

[0041] like Figure 2 As shown, the air distribution unit 4 includes an upper sliding seat 41 and a lower sliding seat 42 that are vertically slidably disposed inside the drying chamber.

[0042] Several vertical partitions 43 are arranged horizontally between the upper slide 41 and the lower slide 42.

[0043] A number of guide strips 44 are arranged between two adjacent vertical partitions 43, and the two adjacent guide strips 44 together form a drainage channel.

[0044] A return spring 45 is fixedly installed between one of the inner walls of the drying oven and the sliding seat 42.

[0045] Two opposing drainage channels are distributed in a figure-eight shape, and the two adjacent drainage channels enclose each other to form a funnel-shaped exhaust channel, so as to evenly and efficiently disperse the hot airflow to several placement plates 22, thereby reducing the difference in the degree of drying of each ceramic flat film preform in the same time period, improving the drying uniformity of all ceramic flat film preforms, and avoiding cracks in some ceramic flat film preforms due to large differences in the degree of drying.

[0046] like Figure 2 and Figure 3 As shown, the container 2 includes a support frame 21 fixedly mounted on the top of the support plate 8.

[0047] Several placement plates 22 are vertically and fixedly installed in the support frame 21. Several guide channels 23 are arranged in parallel along the longitudinal and transverse directions on the top of the placement plates 22. The several guide channels 23 are staggered and divide the top of the placement plates 22 into several support blocks 24.

[0048] The vertical cross-sectional shape of the guide channel 23 is a trapezoid with a narrow top and a wide bottom, and the end face of the guide channel 23 corresponds to the flow channel. This design allows the hot airflow dispersed towards the placement plate 22 to be partially dispersed and flowed to the bottom of the ceramic flat film preform. Combined with the hot airflow flowing from the top of the ceramic flat film preform, the top and bottom of the ceramic flat film preform are dried simultaneously, improving its drying efficiency and uniformity.

[0049] like Figure 3 and Figure 4 As shown, the intermittent deflection part 6 includes four elastic elements 63 circumferentially fixed on the support ring 1. Each elastic element 63 includes a sleeve fixed to the bottom of the support ring 1 and a rod slidably inserted into the sleeve at one end. A compression spring is provided inside the sleeve, with its two ends fixed to the end face inside the sleeve and the rod, respectively. A limiting block 64 is fixed to the free end of the elastic element 63 and is fixed to the free end of the rod. A limiting groove 66 is provided on the arc surface of the support plate 8, corresponding to the limiting block 64. A tension spring 65 is fixed between the outside of the wedge-shaped lever 61 and the bottom of the support plate 8. A worm gear 62 is rotatably sleeved on the outside of the support shaft 7, and a wedge-shaped lever 61 is fixed on the worm gear 62. The limiting groove 66, the wedge-shaped lever 61, and the tension spring 65 are distributed circumferentially on the support plate 8.

[0050] The free end of the wedge lever 61 is an inclined surface, and the circumferential path of the inclined surface of the wedge lever 61 covers the limiting groove 66.

[0051] The reciprocating drive component 5 includes a rotating shaft rotatably disposed inside the drying oven and a drive motor for driving the rotating shaft to rotate. A cam is fixedly sleeved on the outside of the rotating shaft. The cam is used to push the container 2 to move laterally back and forth. A worm is provided at one end of the rotating shaft. The worm meshes with the worm wheel 62. The drive motor drives the rotating shaft to rotate, and the rotating shaft drives the cam to rotate. The inner wall of the sliding seat 42 abuts against the arc-shaped surface of the cam, and the return spring is located outside the sliding seat 42. Therefore, when the cam rotates, it can push the sliding seat 42 to move laterally back and forth in a straight line, so that the hot airflow blown out by the hot air blower 3 can be more evenly distributed and guided to each placement plate 22 on the support frame 21, so as to use the hot airflow to accelerate the drying of the ceramic flat film preform on the placement plate 22. The rotating shaft drives the worm to rotate synchronously and drives the worm wheel 62 and the wedge-shaped lever 61 to rotate synchronously and stretch the tension spring 65. The inclined surface of the wedge-shaped lever 61 is inserted into the limiting groove 6. When the limiting block 64 inside the 6th cavity contacts and abuts, the wedge-shaped lever 61 will gradually push the limiting block 64 out of the limiting groove 66 during continuous rotation, until the circumferential locking state of the limiting block 64 and the limiting groove 66 together fixing the support plate 8 is released. When the limiting block 64 is completely disengaged from the inside of the limiting groove 66, the support plate 8 will deflect rapidly under the pull of the tension spring 65 until another limiting block 64 is inserted into the limiting groove 66, and the support plate 8 will be locked again. In this way, the wedge-shaped lever 61 will intermittently pull the support plate 8 to deflect 90° four times when it deflects one revolution, so that the longitudinal and transverse guide grooves 23 alternately correspond to the flow channel, so as to guide the hot airflow to the bottom of the ceramic flat film preform, which facilitates the uniform drying of the ceramic flat film preform. With the hot airflow flowing from the top of the ceramic flat film preform, the top and bottom of the ceramic flat film preform can be dried at the same time, improving its drying efficiency and uniformity.

[0052] Working principle: The drive motor drives the rotating shaft to rotate, which in turn drives the cam to rotate. The inner wall of the sliding seat 42 abuts against the arc-shaped surface of the cam, and the return spring is located outside the sliding seat 42. Therefore, when the cam rotates, it can push the sliding seat 42 to move laterally and reciprocally in a straight line, which can distribute the hot airflow blown out by the hot air blower 3 more evenly to each placement plate 22 on the support frame 21, so as to use the hot airflow to accelerate the drying of the ceramic flat film preform on the placement plate 22. The rotating shaft drives the worm to rotate synchronously and drives the worm wheel 62 and the wedge-shaped lever 61 to rotate synchronously and stretch the tension spring 65. When the inclined surface of the wedge-shaped lever 61 contacts and abuts against the limiting block 64 inserted in the limiting groove 66, the wedge-shaped lever 61 will gradually push the limiting block 64 out of the limiting groove 66 during continuous rotation, until the limiting block 64 and the limiting groove 66 jointly fix the support plate 8. In the circumferential locking state, when the limiting block 64 is completely disengaged from the limiting groove 66, the support plate 8 deflects rapidly under the pull of the tension spring 65. During this process, all the limiting blocks 64 simultaneously abut against the arc surface of the support plate 8. When the limiting groove 66 corresponds to another limiting block 64, the other limiting block 64 is inserted into the limiting groove 66 under the push of the elastic element 63, and the support plate 8 is locked again. In this way, when the wedge lever 61 deflects one revolution, it will intermittently pull the support plate 8 to deflect 90° four times, so that the longitudinal and transverse guide grooves 23 alternately correspond to the flow channel, so as to guide the hot airflow to the bottom of the ceramic flat film preform, which facilitates the uniform drying of the ceramic flat film preform. In conjunction with the hot airflow flowing from the top of the ceramic flat film preform, the top and bottom of the ceramic flat film preform are dried simultaneously, improving its drying efficiency and uniformity.
