Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic tube processing equipment, and in particular relates to a ceramic tube outer film drawing device. Background Art

[0002] Ceramic membranes offer excellent properties such as high separation precision, excellent chemical stability, resistance to acids and alkalis, high temperatures, resistance to organic solvents, and high mechanical strength. They hold significant potential for application in industrial separation and filtration, as well as in specialized water treatment applications such as those involving severe corrosion, high temperatures, and high levels of suspended solids. The ceramic support is the primary structure of the ceramic membrane, providing the necessary mechanical strength. Currently, ceramic membranes are typically fabricated using immersion coating, spraying, or manual coating. The immersion coating method involves immersing the ceramic tube in the membrane solution and slowly pulling it out, forming a thin film on the tube surface. This process method makes it difficult to control the thickness of the membrane layer to the required accuracy. Changes in the composition and moisture of the membrane liquid during multiple immersion processes will lead to poor uniformity of the membrane layer structure, and the membrane liquid often needs to be replaced multiple times, resulting in low production efficiency. The spray gun of the spray method is prone to clogging of the membrane liquid, and the spraying process easily causes a large amount of membrane liquid waste and pollutes the environment, which is not conducive to cost control and environmental protection. The coating method relies on manual operation to evenly coat the membrane liquid on the surface of the ceramic tube, which is labor-intensive and has low production efficiency. The quality of the membrane layer is greatly affected by the skill level of the operator, making it difficult to achieve large-scale production. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content

[0026] Please also refer to Figures 1 to 5 Now, the ceramic tube outer film drawing device provided by the embodiment of the utility model is described.

[0027] like Figures 1 to 5 As shown, the ceramic tube outer film drawing device of the present invention includes a base 100, a liquid storage film drawing device 200 and a slide 300, the base 100 is provided with a track 110, the liquid storage film drawing device 200 is provided on the base 100, the liquid storage film drawing device 200 includes a liquid storage tank 210 and a coating chamber 220, the liquid storage tank 210 is connected to the coating chamber 220, the coating chamber 220 is provided with a coating hole 240 in the middle for allowing the ceramic tube to pass through, and the slide 300 is slidably mounted on the track 110 The slide 300 passes through the bottom of the liquid storage and film pulling device 200, and the two ends of the slide 300 are respectively arranged on both sides of the liquid storage and film pulling device 200. The two ends of the slide 300 are respectively provided with a clamping plate 321 and a liquid sealing rod 324 that can clamp the ceramic tube. The clamping plate 321 is arranged at one end of the slide 300, and the liquid sealing rod 324 is arranged at the other end of the slide 300. The end face of the liquid sealing rod 324 can abut against the ceramic tube, and the liquid sealing rod 324 can be inserted into the coating hole 240.

[0028] Specifically, the liquid storage and film drawing device 200 is arranged in the middle of the base 100, and the two ends of the slide 300 are respectively arranged on both sides of the liquid storage and film drawing device 200. The two ends of the slide 300 clamp the ceramic tube and slide back and forth on the track 110, so that the ceramic tube passes back and forth through the coating hole 240 to draw the outer film.

[0029] Exemplarily, the clamping plate 321 is arranged at one end of the slide 300, and the liquid sealing rod 324 is arranged at the other end of the slide 300. The end face of the liquid sealing rod 324 can abut against the ceramic tube, and the liquid sealing rod 324 can be inserted into the coating hole 240. One end of the ceramic tube abuts the clamping plate 321, and the other end abuts against the end face of the liquid sealing rod 324, thereby clamping the ceramic tube. When the ceramic tube is not clamped, the liquid sealing rod 324 is inserted into the coating hole 240 to block the coating hole 240, preventing the film liquid in the coating chamber 220 from flowing out of the coating hole 240 and causing waste. Moreover, the liquid sealing rod 324 also plays a positioning role in clamping the ceramic tube. The end face of the liquid sealing rod 324 abuts against the ceramic tube so that the height and position of the ceramic tube can be aligned with the coating hole 240 like the liquid sealing rod 324, making it convenient for the liquid sealing rod 324 to pass through the coating hole 240 to pull the film and apply the film.

[0030] Illustratively, a baffle 323 is provided at one end of the slide 300 close to the clamping plate 321, and a spring 322 is connected to the baffle 323. The end of the spring 322 away from the baffle 323 is connected to the clamping plate 321. The elastic force generated by the compression spring 322 drives the clamping plate 321 to clamp the ceramic tube, which can adapt to ceramic tubes with slight differences in length. In addition, the spring 322 drives the clamping plate 321 to clamp the ceramic tube, which facilitates the installation and removal of the ceramic tube.

[0031] Exemplarily, a support block 310 is provided below the slide 300 and below the liquid storage and film pulling device 200, respectively. The support block 310 is provided with a groove 311 for accommodating the ceramic tube. The support block 310 is below the ceramic tube and can support and catch the ceramic tube when the ceramic tube falls without being clamped to prevent the ceramic tube from being broken. The groove 311 can accommodate the ceramic tube to prevent the ceramic tube from rolling off the support block 310.

[0032] For example, a recovery tank 120 is provided on the base 100, and the recovery tank 120 is arranged below the liquid storage and film drawing device 200. When the ceramic tube passes through the coating hole 240 back and forth for coating, some film liquid will inevitably flow out of the coating hole 240 and fall down. The recovery tank 120 stores these film liquids for recycling.

[0033] Exemplarily, a fixing frame 140 is fixedly connected to both sides of the base 100, and the liquid storage and film pulling device 200 is fixedly connected to the fixing frame 140. The liquid storage and film pulling device 200 is installed through the fixing frame 140, so that the liquid storage and film pulling device 200 can be suspended above the recovery tank 120, so that the recovery tank 120 can recover the film liquid when the film liquid falls.

[0034] Exemplarily, silicone sheets 230 are provided on both sides of the coating chamber 220, and the coating hole 240 is opened in the center of the silicone sheet 230. The uniform scraping of the silicone sheet 230 makes the film layer on the surface of the ceramic tube more uniform, improves the film drawing quality, and reduces manual operation. The coating process of the ceramic tube can be completed continuously and quickly, which significantly improves production efficiency. Moreover, if the position of the ceramic tube is offset when passing through the coating hole 240, it may contact the silicone sheet 230 at the edge of the coating hole 240. The silicone sheet 230 is not easy to scratch the ceramic tube.

[0035] Exemplarily, the base 100 is fixedly connected to support legs 130, and the support legs 130 are respectively arranged at both ends and the middle of the bottom of the base 100. Since the base 100 needs to be provided with a track 110 to allow the slide 300 to slide back and forth, the base 100 is relatively long and has a large span, so it is necessary to provide support legs 130 in the middle of the bottom to provide support to prevent the base 100 from being concave and deformed in the middle.

[0036] In other embodiments, the slide 300 can also be driven by a motor to slide and the ceramic tube can be coated. First, the slide 300 is moved to the starting position, the coating hole 240 is closed by the sealing rod 324, and the film liquid exceeding the height of the sealing rod 324 is added to the liquid storage tank 210. The ceramic tube is clamped by the clamping plate 321 and the sealing rod 324, and the slide 300 is driven by a motor to move, and the ceramic tube is introduced into the coating chamber 220 at a uniform moving speed. As the slide 300 moves, the ceramic tube passes through the coating hole 240, and the silicone sheet 230 scrapes the surface of the ceramic tube, evenly coating the film liquid on the ceramic tube, and removing excess film liquid to complete the coating. The motor drives the slide 300 to allow the slide 300 to keep sliding at a uniform speed, and the coating is more uniform.

[0037] The ceramic tube outer film stretching device provided by the present invention has the following beneficial effects compared with the prior art:

[0038] The base 100 of the present invention is provided with a track 110, so that the slide 300 can slide back and forth on the track 110, and the liquid storage tank 210 of the liquid storage and film drawing device 200 is used to store film liquid. The liquid storage tank 210 is connected with the film coating chamber 220 so that the film liquid in the liquid storage tank 210 can flow into the film coating chamber 220 to fill the film coating chamber 220. A film coating hole 240 is opened in the middle of the film coating chamber 220, and the film coating hole 240 can allow the ceramic tube to pass through, so that the film liquid in the film coating chamber 220 can be coated on the outer film of the ceramic tube during the process of the ceramic tube passing through the film coating hole 240. After the ceramic tube passes through the film coating hole 240 and consumes the film liquid, since the liquid storage tank 210 is connected with the film coating chamber 220, the liquid storage tank 210 can continuously transport film liquid to the film coating chamber 220, keep the interior of the film coating chamber 220 filled with film liquid, and allow the ceramic tube to pass through When coating the film hole 240, the coating of the film liquid is more uniform. Clamping plates 321 and sealing rods 324 are set at both ends of the slide 300 to clamp the ceramic tube. The slide 300 slides back and forth on the track 110 to drive the sliding ceramic tube to pass through the coating hole 240 back and forth for film drawing and coating. By allowing the ceramic tube to pass through the coating hole 240 for film drawing and coating, the film liquid is not easily wasted, and the amount of film liquid used is small. Moreover, since the coating chamber 220 is filled with film liquid, the ceramic tube passes through the coating hole 240 for coating, and the outer surface of the ceramic tube is evenly coated with the film liquid, so the film formation will be more uniform. The slide 300 slides back and forth on the track 110 of the base 100 to drive the ceramic tube to pass through the coating hole 240 for film drawing and coating, thereby reducing the intensity of manual labor, improving the film drawing production efficiency, and being suitable for large-scale production.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
