Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane tube straightening technology, and in particular to a ceramic membrane tube straightening machine. Background Technology

[0002] Silicon carbide ceramic membrane tubes possess excellent high-temperature resistance, thermal shock resistance, corrosion resistance, and high-throughput properties, along with a long service life, making them a key material in environmental pollution control fields such as high-temperature flue gas purification, oil-water separation, and gas separation. Silicon carbide ceramic membrane tubes typically consist of a support, a transition layer, and a separation layer. The manufacturing process includes mixing, kneading, extrusion molding, preform shaping, drying, membrane attachment, re-drying, and sintering. The support is usually formed by kneading and extrusion, but the support at this stage is relatively soft and prone to deformation; therefore, straightening and drying are necessary for shaping.

[0003] The common method for straightening and shaping is to wrap the membrane tube with felt and manually turn it over, then place it in an oven for heating, and then manually turn it over repeatedly to complete the shaping. However, this method requires manual operation around the clock, and the turning angle is difficult to control precisely, which easily leads to poor roundness and straightness of the membrane tube support, resulting in low production efficiency and low finished product qualification rate.

[0004] To address the above problems, a ceramic membrane tube straightening machine is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ceramic membrane tube straightening machine, which aims to solve the problems of complex operation, poor roundness and straightness of membrane tube support, and low product qualification rate in existing ceramic membrane tube straightening methods.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 2The present invention provides an embodiment of a ceramic membrane tube straightening machine, comprising a frame 7, wherein a drive assembly is provided inside the frame 7, the drive assembly comprising a variable frequency motor 1 and a reducer 2, both of which are installed inside the frame 7. The output end of the variable frequency motor 1 is connected to the reducer 2 via a belt, and the output end of the reducer 2 is connected to the end of the roller 3 via a chain 10. The drive assembly is used to transmit power evenly and stably to the next structure, ensuring that the power output during the straightening process is stable and adjustable.

[0024] A condensing dehumidifier dryer 5 is mounted on top of the frame 7. Inside the condensing dehumidifier dryer 5 is a straightening assembly, which includes multiple rollers 3 arranged side-by-side. A humidity sensor 4 is positioned directly above each roller 3 to detect ambient humidity in real time and transmit the data to a PLC control box 6. The PLC control box 6 is electrically connected to the condensing dehumidifier dryer 5, the humidity sensor 4, and the variable frequency motor 1. Based on the humidity sensor's readings, the PLC control box 6 controls the heating temperature of the condensing dehumidifier dryer 5 and the rotational speed of the rollers 3, allowing for timely adjustment of drying parameters. This ensures that the ceramic membrane tubes maintain suitable humidity conditions during straightening, preventing excessively high or low humidity from affecting product quality. The rollers 3 are rotatably connected inside the condensing dehumidifier dryer 5, and one end of each roller 3 is equipped with a spacing adjustment block 8. The spacing between the rollers 3 can be flexibly adjusted using the spacing adjustment block 8 to accommodate ceramic membrane tubes of different diameters. Two adjacent rollers 3 are connected by sprockets 9, and the outer side of one of the rollers 3 is connected to the drive assembly via a chain 10, ensuring that all rollers 3 rotate synchronously and achieve uniform straightening. This improves production efficiency, ensures the straightening accuracy and surface quality of the ceramic membrane tube, and meets high-standard production requirements.

[0025] Working Principle: A variable frequency motor 1 drives a reducer 2 via a belt. The reducer 2 transmits power to the rollers 3 via a chain 10, ensuring a smooth and even power transfer for straightening the ceramic membrane tubes. Multiple rollers 3 are installed side-by-side within the condenser-dryer 5 at the top of the frame 7. Humidity sensors 4 are mounted above the rollers 3 to monitor ambient humidity in real time and provide feedback to the PLC control box 6. The PLC control box 6 adjusts the temperature of the condenser-dryer 5 and the rotational speed of the rollers 3 based on the humidity data to ensure suitable humidity conditions for the ceramic membrane tubes during straightening, preventing excessively high or low humidity from affecting product quality. The distance between the rollers 3 is adjusted by a spacing adjustment block 8 to accommodate membrane tubes of different diameters. A sprocket 9 and chain 10 ensure synchronized rotation of all rollers 3, achieving uniform straightening and improving production efficiency, precision, and surface quality to meet high production standards.
