Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, and in particular to a ceramic membrane extrusion air support. Background Technology

[0002] During the production of ceramic membranes, the green body needs to be extruded onto an air support for cutting. Due to the large weight of large-size tubular ceramic membranes, air is introduced into the air support during the extrusion of the green body. This allows the green body to adhere to the groove of the air support and move under pressure under the pressure of the gas, thus avoiding product deformation caused by friction during the extrusion process.

[0003] Once the green blank has been extruded to the specified length, it stops moving and is then cut. When moving the green blank to the drying room, the air tray is flipped over to turn it out; however, this flipping process can easily deform the green blank, and improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic film extrusion air support that will not cause deformation of the green body when it is moved to the drying room.

[0005] This utility model proposes a ceramic film extrusion air support, including a base frame, a receiving frame, and a drying rod. The receiving frame is fixedly mounted on the base frame and includes a bottom shell and an air support plate. The air support plate is disposed inside the bottom shell, and a ventilation cavity is formed between the bottom shell and the air support plate. An air inlet pipe communicating with the ventilation cavity is provided at the bottom end of the bottom shell. Several air holes are formed on the surface of the air support plate. A groove is formed on the surface of the air support plate, and a receiving groove is formed on the surface of the drying rod. Several through holes are formed through the drying rod. The drying rod is embedded in the groove of the air support plate, and the bottom surface of the drying rod can fit against the inner sidewall of the groove. The through holes are connected to the air holes.

[0006] Preferably, a plurality of handles are fixedly provided on both sides of the drying rod, and the plurality of handles are evenly distributed along the length direction of the drying rod.

[0007] Preferably, the base frame includes a base frame, a pair of vertical rods and several diagonal rods. The two vertical rods are vertically fixed at both ends of the base frame, and the several diagonal rods are inclined. The two ends of the diagonal rods are respectively fixed to the vertical rods and the base frame.

[0008] Preferably, the base frame further includes a crossbar and several placement rods, the two ends of the crossbar being fixed to two vertical rods respectively, and the several placement rods being horizontally fixed on the crossbar.

[0009] Preferably, one end of the groove passes through the bottom shell, and an installation ring is fixedly provided at the end of the bottom shell through which the groove passes. A feeding ring is vertically fixed on one of the vertical rods, and the feeding ring is embedded in the installation ring.

[0010] Preferably, the end of the bottom shell furthest from the mounting ring is adjusted and mounted on another vertical rod, and the feed ring and the mounting ring are fitted with a clearance.

[0011] Preferably, a lifting groove is formed in the vertical rod, and a screw is horizontally fixed at one end of the bottom shell. The screw passes through the lifting groove, and a pair of abutment nuts are screwed on the screw. The two abutment nuts are respectively abutted and fixed to both sides of the vertical rod.

[0012] Preferably, the screw is provided with a pair of washers, which abut against the vertical rod and the abutting nut.

[0013] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0014] 1. After the green body is extruded into the receiving tank, the drying rod is moved directly to move the green body to the drying room for drying. This avoids deformation caused by the green body being turned and moved. This utility model is especially suitable for large-sized honeycomb ceramic films.

[0015] 2. A lifting groove is formed in the vertical rod, and a screw is horizontally fixed at one end of the bottom shell. The screw passes through the lifting groove, and the two washers are pressed against the vertical rod by the action of the abutment nut. This allows the screw to be adjusted in height within the lifting groove. The feed ring and the mounting ring are set with a clearance fit. After adjustment, the end of the bottom shell away from the feed ring is lower, so as to facilitate the sliding of the green blank.

[0016] 3. An air inlet pipe connected to the ventilation cavity is provided at the bottom end of the bottom shell. Gas is introduced into the ventilation cavity through the air inlet pipe, so that the gas passes through the air holes and through holes, and the green embryo is suspended and moved under the action of air pressure to be squeezed out, so as to prevent the green embryo from being deformed due to friction.

[0025] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-7 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0026] Reference Figures 1-4 A ceramic film extrusion air support includes a base frame 1, a receiving frame 2, and a drying rod 3. The receiving frame 2 is mounted on the base frame 1. The receiving frame 2 includes a bottom shell 21 and an air support plate 22. The air support plate 22 is fixedly mounted on the bottom shell 21, forming a ventilation cavity 23 between the bottom shell 21 and the air support plate 22. Several air inlet pipes 24 are provided at the bottom end of the bottom shell 21, so that each air inlet pipe 24 is connected to the ventilation cavity 23. The surface of the air support plate 22 has grooves 221, and several air holes 222 are formed through the air support plate 22.

[0027] Reference Figure 1 and Figure 5 A receiving groove 31 is formed on the surface of the drying rod 3, and several through holes 32 are formed in the drying rod 3. After the drying rod 3 is inserted into the groove 221 of the air support plate 22, the bottom of the drying rod 3 is in contact with the inner side wall of the air support plate 22. The through holes 32 on the drying rod 3 are connected to the air holes 222 of the air support plate 22, and the green embryo is put into the receiving groove 31 of the drying rod 3.

[0028] Reference Figure 1 and Figure 6The base frame 1 includes a base frame 11, a pair of vertical rods 12, several diagonal rods 13, a horizontal rod 14, and several placement rods 15. The two vertical rods 12 are vertically fixed at both ends of the base frame 11. The diagonal rods 13 are inclined, with both ends fixed to the vertical rods 12 and the base frame 11 respectively, ensuring the two vertical rods 12 remain stable. Both ends of the horizontal rod 14 are fixed to the two vertical rods 12, keeping the horizontal rod 14 horizontal. One end of each placement rod 15 is fixed to the horizontal rod 14, also keeping the placement rods 15 horizontal and evenly distributed along the length of the horizontal rod 14. The placement rods 15 are used to hold spare drying rods 3.

[0029] Reference Figure 2 and Figure 6 To facilitate the loading of the green embryo into the receiving groove 31 of the drying rod 3, a groove 221 is used to pass through one end of the bottom shell 21, allowing the green embryo to pass through from one end of the bottom shell 21 into the receiving groove 31 of the drying rod 3. To ensure that the bottom shell 21 is stable on the base frame 1, an installation ring 25 is fixedly provided at the end of the bottom shell 21 through which it is passed. Correspondingly, a feeding ring 121 is vertically fixed on one of the vertical rods 12, and the feeding ring 121 is embedded in the installation ring 25, thereby supporting the installation ring 25 and one end of the bottom shell 21.

[0030] Reference Figure 1 The green blank is extruded from the feed ring 121 into the receiving groove 31 of the drying rod 3, and during the extrusion process, the green blank directly adheres to the surface of the drying rod 3. Gas is introduced into the ventilation chamber 23 from the air inlet pipe 24, so that the gas passes through the air holes 222 and through holes 32, causing the green blank to be suspended and moved under the action of air pressure, thus preventing deformation of the green blank due to friction. After the green blank is extruded to the specified length, it is cut. Finally, the drying rod 3 is moved directly to the drying room to dry, avoiding deformation caused by the turning and moving of the green blank. At the same time, the several through holes 32 opened at the bottom of the drying rod ensure that moisture can be discharged from both the top and bottom of the green blank, achieving uniform drying. In order to facilitate the movement of the drying rod 3, several handles 33 are fixedly installed on both sides of the drying rod 3, and the handles 33 are evenly distributed along the length of the drying rod 3.

[0031] Reference Figure 1 and 7To facilitate the smooth entry of the green embryo into the receiving groove 31 of the drying rod 3, a clearance fit is used between the feeding ring 121 and the mounting ring 25, and the other end of the bottom shell 21 and the vertical rod 12 are adjustable in height. This keeps the receiving frame 2 and the drying rod 3 tilted downwards, making it easier for the green embryo to slide in. To enable the adjustment of one end of the bottom shell 21, a lifting groove 122 is formed on the vertical rod 12. Correspondingly, a screw 4 is horizontally fixed at one end of the bottom shell 21, with one end of the screw 4 passing through the lifting groove 122. A pair of abutment nuts 41 and a pair of washers 42 are provided on the screw 4, with the two washers 42 located on both sides of the vertical rod 12. When it is necessary to slide the green embryo from the feeding ring 121 into the receiving groove 31 of the drying rod 3, the abutment nuts 41 are loosened, so that the screw 4 abuts against the bottom end of the lifting groove 122, thus keeping the receiving frame 2 and the drying rod 3 tilted downwards. After the green blank is loaded into the receiving groove 31, lift the bottom shell 21 to keep it horizontal, and turn the abutment nuts 41 on both sides so that the washer 42 is pressed between the abutment nut 41 and the vertical rod 12, thereby keeping the screw 4 and the vertical rod 12 in a stable position.

[0032] The specific implementation principle of this application embodiment is as follows: When the ceramic film extrusion air support is needed, the drying rod 3 is embedded in the groove 221 of the air support plate 22. The bottom of the drying rod 3 abuts against the inner wall of the groove 221 of the air support plate 22, and the through hole 32 on the surface of the drying rod 3 is connected to the air hole 222 of the air support plate 22. The ceramic film preform is extruded onto the air support by the extruder. To facilitate the preform sliding into the receiving groove 31 of the drying rod 3, the abutment nuts 41 on both sides of the vertical rod 12 are loosened, so that the screw 4 abuts against the bottom end in the lifting groove 122, thereby making the end of the receiving frame 2 with the screw 4 at a lower height. The preform passes through the feed ring 121 into the receiving groove 31 of the drying rod 3 and slides along the inclined direction of the drying rod 3.

[0033] Simultaneously, air is introduced into the ventilation chamber 23 through the air inlet pipe 24. The introduced air passes through the air holes 222 and the through holes 32, causing the green blank to be suspended and extruded under air pressure, preventing deformation of the green blank due to friction. This continues until one end of the green blank abuts against the end wall of the bottom shell 21, after which the green blank is cut off from the feed ring 121. After the green blank is loaded into the receiving groove 31 of the drying rod 3, the receiving frame 2 equipped with the screw 4 is lifted, making the receiving frame 2 horizontal. Then, the abutment nuts 41 on both sides of the vertical rod 12 are tightened, causing the gasket 42 to abut against the vertical rod 12, thus ensuring the receiving frame 2 remains horizontally stable. Finally, the drying rod 3 is moved directly by the handle 33 to the drying room to dry the green blank, avoiding deformation caused by the green blank being turned and moved. Meanwhile, several through holes 32 at the bottom of the drying rod ensure that moisture can be drained from both the top and bottom of the green blank, achieving uniform drying.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be protected by the present invention.
