Description

Technical Field:

[0002] The present invention relates to MBR membrane production equipment, and particularly to a support tube supply assembly for MBR membrane production. Background Art:

[0004] During MBR membrane production, the support tubes need to be supplied continuously. The support tubes wound on the rollers are subjected to membrane formation treatment after passing through the wire winding wheel and then provide a framework for MBR membrane production. The support tubes on each roller can only supply production for about three hours. In the prior art, the device for placing the rollers is a transmission shaft with a tapered shank. The two ends of the transmission shaft are in interference fit with the inner ring of the bearing, and the bearing is fixed on the bracket through the bearing seat. When the support tubes are exhausted, it is necessary to open the gland of the bearing seat, take out the bearing and the transmission shaft, separate the interference-fitted bearing and the transmission shaft, remove the roller fixed on the transmission shaft, reinstall the roller with the support tubes, then install the bearing on the transmission shaft, and fix both ends on the bracket through the bearing seat. The entire replacement process is time-consuming and laborious. Multiple replacements can cause irreparable damage to the bearing and the transmission shaft, increase production costs, and reduce production efficiency. Summary of the Invention:

[0006] To overcome the above problems, it would be advantageous for the present invention to provide a support tube supply assembly for MBR membrane production with a simple structure and low replacement cost.

[0007] For this purpose, the present invention provides a support tube supply assembly for MBR membrane production. The technical solution it adopts is: including a bracket and at least two groups of support tube supply devices for MBR membrane production placed on the bracket, characterized in that: each group of support tube supply devices for MBR membrane production includes a roller for winding the support tubes thereon, a transmission shaft for installing the roller thereon, a pair of bearing structures installed on the bracket for rolling support of the transmission shaft, each bearing structure includes a pair of bearings installed on the bracket and arranged at intervals, the gap width between the two bearings is less than the diameter of the transmission shaft, one end of the transmission shaft is placed on the gap between the two bearings of one bearing structure, and the other end of the transmission shaft is placed on the gap between the two bearings of the other bearing structure.

[0008] A further technical feature of the present invention is:

[0009] For each of the two bearings corresponding to each bearing structure on the bracket, a detachable upper-open oil collecting tank is provided. Each oil collecting tank includes a box body, two scraping plates placed on the inner wall of the box for cleaning the dirt on the bearing surface, and also includes an oil filter screen placed inside the oil collecting tank.

[0010] Except for the oil collecting tank of the pair of bearing structures at the lowermost end, the bottom of the oil collecting tank corresponding to the bearing structures in each other group of the support pipe supply device for MBR membrane production is sloped, and an oil outlet is provided at the lowest point. The oil outlet is connected to a rubber pipe, and the other end of the rubber pipe is arranged above one end of the transmission shaft in the next group of support pipe supply devices for MBR membrane production to provide lubricating oil for the contact surface between the transmission shaft and the bearing.

[0011] The central axis of the transmission shaft is not higher than the uppermost edge of the bearing.

[0012] The transmission shaft has a taper shank, and the roller is tightly installed on the transmission shaft by means of the slope of the taper shank, or the transmission shaft is provided with a keyway or a key, and correspondingly, the roller is provided with a key or a keyway.

[0013] The present invention also discloses a support pipe supply device for MBR membrane production, which is characterized by including a roller for winding a support pipe thereon, a transmission shaft for installing the roller thereon, and a pair of bearing structures for rotatably supporting the transmission shaft. Each bearing structure includes a bearing bracket, and a pair of bearings are rotatably installed on the bearing bracket. The gap width between the pair of bearings is smaller than the diameter of the transmission shaft, and both ends of the transmission shaft are respectively placed on the gaps between the pair of bearings on each of the pair of bearing brackets.

[0014] Further, the central axis of the transmission shaft is not higher than the uppermost edge of the bearing.

[0015] The transmission shaft has a taper shank, and the roller is tightly installed on the transmission shaft by means of the slope of the taper shank, or the transmission shaft is provided with a keyway or a key, and correspondingly, the roller is provided with a key or a keyway.

[0016] For each pair of bearings in each bearing structure, the bearing bracket is provided with a detachable oil collecting tank with an upper opening. Each oil collecting tank includes a box body, two scrapers for cleaning dirt on the bearing surface placed on the inner wall of the box body, and also includes an oil filter screen placed inside the oil collecting tank.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, the rolling friction between the transmission shaft and the bearing is very small, resulting in very little wear between the transmission shaft and the bearing, which greatly reduces the replacement cost. Since one end of the transmission shaft is placed on the gap between two bearings of a bearing structure, and the other end of the transmission shaft is placed on the gap between two bearings of another bearing structure, when the support tube is exhausted, the transmission shaft can be directly removed. After the roller is replaced, the transmission shaft with the fixed roller can be placed back between the two bearing structures. The whole process only takes about one minute, greatly improving the work efficiency. Moreover, this invention avoids the irreparable damage caused by frequent disassembly and assembly of the bearing and the transmission shaft, while also improving the production efficiency and saving labor costs.

[0019] 2. For each of the two bearings corresponding to each bearing structure on the bracket, there is a detachable oil collecting tank with an upper opening. Each oil collecting tank includes a box body, two scraping plates for cleaning the dirt on the bearing surface placed on the inner wall of the box, and an oil filter screen placed inside the oil collecting tank. Through this structural arrangement, it is convenient to add lubricating oil to the contact surface between the transmission shaft and the bearing, reducing the friction coefficient. The scraping plates can also effectively clean the dirt adhered to the bearing surface. In practical applications, the distance between the scraping plate and the bearing surface is set to be less than 2MM. The scraping plates can scrape off the impurities and dirt accumulated on the bearing surface in the environment, and the impurities and dirt are separated by the oil filter screen. When the system needs to be cleaned, the oil collecting tank can be removed and cleaned.

[0020] 3. Except for the oil collecting tanks of the pair of bearing structures at the lowermost end, the bottoms of the oil collecting tanks corresponding to the bearing structures in each group of MBR membrane production support tube supply devices are in a slope shape, and an oil outlet is provided at the lowest point. The oil outlet is connected to a rubber tube, and the other end of the rubber tube is placed above one end of the transmission shaft in the next group of MBR membrane production support tube supply devices to provide lubricating oil for the transmission shaft and the bearing. Through this structural arrangement, it is convenient to lubricate multiple groups of MBR membrane production support tube supply devices simultaneously. In practical applications, only need to manually add lubricating oil to the transmission shaft of the highest group. The lubricating oil lubricates the contact surface between the transmission shaft and the bearing as the transmission shaft rotates. The excess lubricating oil is filtered by the oil filter screen of the oil collecting tank and then transported to the next group of transmission shafts and bearings through the rubber tube, which can facilitate the addition of lubricating oil and save labor.

[0021] 4. The central axis of the above-mentioned transmission shaft is not higher than the uppermost edge of the bearing. Through this structural arrangement, the transmission shaft can be stably supported on the gap between the bearings, avoiding the risk of falling.

[0022] 5. The above-mentioned transmission shaft has a taper shank, and the roller is tightly installed on the transmission shaft by means of the taper of the taper shank; or the above-mentioned transmission shaft is provided with a keyway or a key, and correspondingly, the roller is provided with a key or a keyway. Through these two structural arrangements, the roller can be detachably installed on the transmission shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will describe the specific embodiments of the present invention in conjunction with the drawings.

[0030] Referring to Figures 1 to 3 , a support tube supply assembly for MBR membrane production, which includes a bracket 1 and three sets of support tube supply devices 2 for MBR membrane production placed on the bracket. Each set of support tube supply devices for MBR membrane production includes a roller 3 for winding the support tube 12 thereon, a transmission shaft 4 for mounting the roller 3 thereon, a pair of bearing structures 5 mounted on the bracket 1 for rolling support of the transmission shaft 4. Each bearing structure 5 includes a pair of bearings 6 spaced apart and mounted on the bracket. The gap width between the two bearings is less than the diameter of the transmission shaft 4. One end of the transmission shaft 4 is placed on the gap between the two bearings of one bearing structure, and the other end of the transmission shaft 4 is placed on the gap between the two bearings of the other bearing structure.

[0031] In this embodiment, a detachable upper-open oil collecting tank 7 is provided on the bracket 1 corresponding to the two bearings 6 of each bearing structure. Each oil collecting tank includes a box body 8, two scrapers 9 placed on the inner wall of the box for cleaning the dirt on the bearing surface, and also includes an oil filter screen 10 placed inside the oil collecting tank. Except for the oil collecting tanks of the pair of bearing structures at the lowermost end, the bottoms of the oil collecting tanks 7 corresponding to the bearing structures in each set of support tube supply devices for MBR membrane production are in a slope shape, and an oil outlet is provided at the lowest point. The oil outlet is connected to a rubber tube 11, and the other end of the rubber tube is placed above one end of the transmission shaft in the next set of support tube supply devices for MBR membrane production to provide lubricating oil for the contact surface between the transmission shaft and the bearing.

[0032] In addition, in this embodiment, the central axis of the transmission shaft 4 is not higher than the uppermost edge of the bearing 6. The transmission shaft has a taper shank, and the roller is tightly mounted on the transmission shaft by means of the slope of the taper shank.

[0033] In practical applications, two sets of support tube supply devices for MBR membrane production or four sets or even more can also be provided for the support tube supply assembly for MBR membrane production. A keyway or a key can also be provided on the transmission shaft 4. Correspondingly, a key or a keyway is provided on the roller. Through the cooperation of the keyway on the transmission shaft with the corresponding key on the roller, or through the cooperation of the key on the transmission shaft with the corresponding keyway on the roller, the roller can be detachably mounted on the transmission shaft.

[0034] In the present invention, the friction between the transmission shaft 4 and the bearing 6 is rolling friction, and the friction force is very small, so that the wear between the transmission shaft 4 and the bearing 6 is very small, which greatly reduces the replacement cost. Since one end of the transmission shaft 4 is placed on the gap between two bearings 6 of a bearing structure 5, and the other end of the transmission shaft 4 is placed on the gap between two bearings 6 of another bearing structure 5, when the support tube is exhausted, the transmission shaft 4 can be directly removed. After the roller 3 is replaced, the transmission shaft 4 with the fixed roller 3 can be placed on the two bearing structures 5 again. The whole process only takes about one minute, which greatly improves the working efficiency. Moreover, this invention avoids the irreparable damage caused by frequent disassembly and assembly of the bearing and the transmission shaft, and at the same time improves the production efficiency and saves the labor cost.

[0035] In addition, a detachable upper-open oil collecting tank 7 is provided on the bracket 1 corresponding to the two bearings 6 of each bearing structure 5. Each oil collecting tank 7 includes a box body 8, two scrapers 9 for cleaning the dirt on the bearing surface placed on the inner wall of the box, and an oil filter screen 10 placed inside the oil collecting tank. Through the setting of this oil tank structure, it is convenient to add lubricating oil to the contact surface between the transmission shaft 4 and the bearing 6, reducing the friction coefficient. The scraper 9 can also effectively clean the dirt adhered to the surface of the bearing 6. In practical applications, the distance between the scraper 9 and the surface of the bearing 6 is set to be less than 2 mm. The scraper 9 can scrape off the impurities and dirt accumulated on the surface of the bearing 6 in the environment. The impurities and dirt are separated by the oil filter screen 10. When the system needs to be cleaned, the oil collecting tank 7 can be removed and cleaned.

[0036] In this embodiment, except for the oil collecting tank 7 of the pair of bearing structures at the lowermost end, the bottom of the oil collecting tank 7 corresponding to the bearing structure 5 in each other group of MBR membrane production support pipe supply devices is in a slope shape, and an oil outlet is provided at the lowest point. The oil outlet is connected to a rubber tube 11, and the other end of the rubber tube 11 is arranged above one end of the transmission shaft in the next group of MBR membrane production support pipe supply devices to provide lubricating oil for the transmission shaft and the bearing. Through this structural arrangement, it is convenient to lubricate multiple groups of MBR membrane production support pipe supply devices simultaneously. In practical applications, only need to manually add lubricating oil to the transmission shaft of the highest group. The lubricating oil lubricates the contact surfaces of the transmission shaft and the bearing as the transmission shaft rotates. The excess lubricating oil is filtered by the oil filter screen of the oil collecting tank and then transported to the next group of transmission shafts and bearings through the rubber tube, which can facilitate the addition of lubricating oil and save labor.

[0037] In practical applications, the central axis of the above-mentioned transmission shaft 4 is not higher than the uppermost edge of the bearing. Through this structural arrangement, the transmission shaft can be stably supported on the gap between the bearings, avoiding the risk of falling.

[0038] In this embodiment, the above-mentioned transmission shaft 4 has a taper shank, and the roller is tightly installed on the transmission shaft by means of the slope of the taper shank. Through this structural arrangement, the roller can be detachably installed on the transmission shaft. In practical applications, it is also possible to set a keyway or a key (not shown in the figure) on the transmission shaft 4, and correspondingly set a key or a keyway (not shown in the figure) on the roller 3, so that the keys and keyways on the two parts cooperate with each other to detachably install the roller 3 on the transmission shaft 4.

[0039] The present invention also discloses an MBR membrane production support pipe supply device, referring to Figure 2 , it includes a roller for winding the support pipe 12 thereon, a transmission shaft 4 for installing the roller 3 thereon, and a pair of bearing structures 5 for rolling and supporting the transmission shaft 4. Each bearing structure 5 includes a bearing bracket (equivalent to Figure 2 's bracket 1), a pair of bearings 6 are rotatably installed on the bearing bracket, the width of the gap between the pair of bearings 6 is smaller than the diameter of the transmission shaft 4, and both ends of the transmission shaft 4 are respectively placed on the gaps between the pair of bearings 6 on their respective bearing brackets. It is the same as other structures of the MBR membrane production support pipe supply device in the above-mentioned MBR membrane production support pipe supply assembly, except that it has an independent bearing bracket, and the oil collecting tank 7 is arranged on the bearing bracket, and the bearing bracket can be split or integral. In this way, when combined and used, it can be applicable to more site layout requirements and can also be used alone.
