Description

Technical Field

[0001] This invention belongs to the field of ceramic filter tube technology, and specifically relates to a reinforced ceramic filter tube device. Background Technology

[0002] According to environmental protection requirements, industrial waste gas and exhaust gas emissions need to be filtered to remove dust from the flue gas in order to reduce pollution. After a certain period of filtration, a certain thickness of dust will accumulate on the outside of the ceramic fiber filter tube in the filter. At this time, it is necessary to use sonic vibration or compressed gas pulse to shake off the dust on the ceramic fiber filter tube. However, since the ceramic fiber filter tube is often long, when sonic vibration or compressed gas pulse is used to clean the ceramic fiber filter tube, it will often cause the ceramic fiber filter tube to vibrate and sway, which can easily lead to the problem of the ceramic fiber filter tube breaking at the connection with the flange.

[0003] A Chinese patent document with publication number CN213192884U proposes a reinforced filter device. It solves the above-mentioned technical problem by providing a reinforcing sleeve at the root of the ceramic fiber filter element. The reinforcing sleeve is made of 304 stainless steel or other metal materials. The reinforcing sleeve increases the contact between the ceramic fiber filter element and the upper support surface when it oscillates. However, the above method does not reinforce the bottom of the ceramic filter tube. The bottom of the filter tube is a free end, which will swing significantly during sonic or pulse cleaning. When the bottom swings, the ceramic filter tube is prone to breaking in the middle.

[0004] Therefore, this invention proposes a reinforced ceramic filter tube device to solve the problem in the prior art where the reinforcing sleeve increases the contact of the upper support surface of the ceramic filter tube, but the bottom of the ceramic filter tube is prone to swinging, causing the ceramic filter tube to break in the middle. The invention improves the external reinforcement structure of the ceramic filter tube, combines it with the ceramic filter tube reinforcement cover, and designs a flexible sliding counterweight ring at the bottom to connect with the upper fixing ring assembly, forming an integrated buffer and reinforcement structure. This structure buffers the high pressure generated by gas and dust filtration during the use of the ceramic filter tube, reducing the probability of the ceramic filter tube breaking or bursting. Summary of the Invention

The inner surface of the side support pad is in contact with the outer surface of the upper end of the ceramic fiber filter tube.

[0009] Preferably, a gray plate is fixedly installed at the bottom of the lower sleeve, and the surface of the gray plate is symmetrically provided with a limiting groove and a dust collection groove, the dust collection groove and the limiting groove are staggered, and a central sleeve is fixedly installed in the middle of the gray plate.

[0010] Preferably, the movable counterweight ring is located in the middle of the inner side of the lower sleeve, and a lower cover ring is fixedly installed on the upper surface of the movable counterweight ring by bolts.

[0011] Preferably, the movable counterweight ring has side pressure plates evenly distributed on its outer side. The upper end of the side pressure plate is rotatably connected to the outer surface of the movable counterweight ring. A return spring is fixedly installed in the middle of the inner surface of the side pressure plate, and one end of the return spring is fixedly connected to the outer surface of the central tube sleeve.

[0012] Preferably, a bottom cover is fixedly installed on the lower surface of the lower sleeve by bolts, and a ash discharge groove is evenly opened on the upper surface of the bottom cover. A spherical bearing is fixedly installed in the middle of the upper surface of the bottom cover.

[0013] Preferably, a support shaft is movably installed inside the spherical bearing seat. The support shaft is located in the middle of the inner side of the movable counterweight ring and the central tube sleeve. A spring telescopic sleeve rod is fixedly installed on the upper surface of the support shaft. An anti-slip support seat is fixedly installed at the upper end of the spring telescopic sleeve rod. The upper surface of the anti-slip support seat is in contact with the bottom surface of the ceramic fiber filter tube.

[0014] Preferably, an adjusting lever is rotatably mounted on the middle of the inner surface of the lower sleeve. The upper end of the adjusting lever is in contact with the outer surface of the support shaft, and the lower end of the adjusting lever is in contact with the outer surface of the side pressure plate. A spring return hinge rod is rotatably mounted on the upper outer surface of the adjusting lever, and the other end of the spring return hinge rod is rotatably connected to the inner surface of the lower sleeve.

[0015] Preferably, the ceramic fiber filter tube is sleeved and installed inside the upper sleeve, the reinforcing cage, and the lower sleeve.

An adjusting lever, an upper fixing ring, an anti-breakage correction rod, and a movable counterweight ring are arranged on the outside of the support shaft, forming a complete integrated cushioning and reinforcement structure. The support shaft, through the cooperation of a spherical bearing, can adaptively deflect according to the vibration and sway of the ceramic fiber filter tube. The adjusting lever, utilizing the lever principle, generates pressure on the inner side pressure plate. A certain amount of reverse squeezing and pushing causes the movable counterweight ring to shift to the opposite side of the swaying ceramic fiber filter tube, adjusting the bottom center of gravity and preventing excessive gravity on the swaying side from causing the ceramic fiber filter tube to break in the middle. Furthermore, the shifting of the movable counterweight ring to the opposite side of the swaying ceramic fiber filter tube will pull the anti-breakage correction rod on the swaying side of the ceramic fiber filter tube to twist, correcting the swaying posture of the ceramic fiber filter tube and helping it to return to its original position. This solves the problem of the ceramic filter tube easily swaying at the bottom, causing it to break in the middle. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1 to 5 This invention provides a technical solution: a reinforced ceramic filter tube device, comprising a perforated plate 1, a pressure plate 2 disposed above the perforated plate 1, ceramic fiber filter tubes 5 evenly distributed between the perforated plate 1 and the pressure plate 2, a reinforcing cage 4 and an anti-breakage straightening rod 6 disposed outside the ceramic fiber filter tubes 5, an upper sleeve 41 fixedly installed at the upper end of the reinforcing cage 4, a lower sleeve 42 fixedly installed at the lower end of the reinforcing cage 4, and an upper fixing ring 61 disposed at the upper end of the anti-breakage straightening rod 6. A movable counterweight ring 62 is provided at the lower end of 6. The ceramic fiber filter tube 5 is sleeved and installed inside the upper sleeve 41, the reinforcing cage 4, and the lower sleeve 42. A top cover 3 is fixedly installed on the upper outer surface of the upper sleeve 41. A Venturi tube 31 is provided in the middle of the lower surface of the top cover 3. The Venturi tube 31 is sleeved and installed inside the upper part of the ceramic fiber filter tube 5. A buffer pad 32 is sleeved and installed on the upper outer part of the ceramic fiber filter tube 5. The lower surface of the buffer pad 32 is in contact with the upper surface of the upper sleeve 41. In this embodiment, the upper sleeve 41, the reinforcing cage 4, and the lower sleeve 42 form a complete anti-breakage ceramic filter tube reinforcement cover, used to install the ceramic fiber filter tubes 5, so that each set of ceramic fiber filter tubes 5 is independently protected. The top cover 3 is used to seal the top of the ceramic fiber filter tubes 5 after installation. The Venturi tube 31 mainly increases the gas flow rate during backflushing by utilizing Bernoulli's principle. The buffer gasket 32 ​​mainly seals the contact position between the top of the ceramic fiber filter tube 5 and the upper sleeve 41, and also plays a certain buffering role. The top cover 3 can completely cover the ceramic fiber filter tubes 5. The upper sleeve 41, the reinforcing cage 4, and the lower sleeve 42 are encapsulated inside the reinforcing cover. The top cover 3 and the upper sleeve 41 can be fixed with bolts or threads. The bolts 13 and the spacing sleeves 12 mainly serve to fix the tube sheet 1 and the pressure plate 2, so that the four sets of ceramic fiber filter tubes 5 can be fixedly installed between the tube sheet 1 and the pressure plate 2. The ceramic gasket 11 mainly serves to seal and reinforce the connection between the ceramic fiber filter tubes 5 and the tube sheet 1. The tube sheet 1 and the pressure plate 2 work together to fix the complete filter component consisting of the four sets of ceramic fiber filter tubes 5 inside the filter. Please see Figures 10 to 15Ball shafts are fixedly installed at the upper and lower ends of the anti-breakage straightening rod 6. The outer surface of the upper fixing ring 61 is fixedly connected to the inner surface of the upper sleeve 41. An upper cover ring 611 is fixedly installed on the upper surface of the upper fixing ring 61 by bolts. Ball bearing seats that are compatible with the anti-breakage straightening rod 6 are evenly distributed between the upper cover ring 611 and the upper fixing ring 61. Spring slides 6111 are evenly distributed on the upper surface of the upper cover ring 611. A side support pad 6112 is slidably installed on the outside of the spring slide 6111. The inner surface of the side support pad 6112 is in contact with the upper outer surface of the ceramic fiber filter tube 5. A gray plate 421 is fixedly installed at the bottom of the lower sleeve 42. A limit groove 4211 and a dust collection groove 42 are symmetrically opened on the surface of the gray plate 421. 13. The ash trough 4213 and the limiting groove 4211 are staggered. A central tube sleeve 4212 is fixedly installed in the middle of the ash plate 421. The movable counterweight ring 62 is set in the middle of the inner side of the lower sleeve 42. The upper surface of the movable counterweight ring 62 is fixedly installed with a lower cover ring 621 by bolts. Ball bearing seats that are compatible with the anti-breakage correction tie rod 6 are evenly distributed between the lower cover ring 621 and the movable counterweight ring 62. Side pressure plates 622 are evenly distributed on the outside of the movable counterweight ring 62. The upper end of the side pressure plate 622 is rotatably connected to the outer surface of the movable counterweight ring 62. A return spring 6221 is fixedly installed in the middle of the inner surface of the side pressure plate 622. One end of the return spring 6221 is fixedly connected to the outer surface of the central tube sleeve 4212. In this embodiment, the upper fixing ring 61 and the upper cover ring 611 form the upper fixing ring assembly, and the movable counterweight ring 62 and the lower cover ring 621 form the lower movable counterweight ring assembly. They are connected in the middle by an anti-breakage correction rod 6, which allows the anti-breakage correction rod 6 to adjust and correct the oscillation of the ceramic fiber filter tube 5, forming an integrated buffer and reinforcement structure. One end of the spring slide 6111 is fixedly mounted with a side support pad 6112 via a spring. Under normal conditions, the side support pad 6112 maintains support contact with the upper side surface of the ceramic fiber filter tube 5 under the action of the spring. Once the ceramic fiber filter tube 5 oscillates, the spring on the deflected side is compressed, causing the corresponding side support pad 6112 to slide along the upper cover ring 611, providing a buffering effect on the ceramic fiber filter tube 5 and preventing rigid breakage of the upper end of the ceramic fiber filter tube 5. The lower gray plate 421... It not only serves to remove ash but also to facilitate the installation of the movable counterweight ring 62. The rod below the side pressure plate 622 passes through the limiting groove 4211 and is equipped with anti-loosening bolts at the bottom. It should be noted that the size of the limiting groove 4211 is larger than the diameter of the rod below the side pressure plate 622 to ensure that the side pressure plate 622 has room to move when the movable counterweight ring 62 is adjusted. The side pressure plate 622 is connected to the outside of the central tube sleeve 4212 through the return spring 6221, so that the movable counterweight ring 62 and the lower cover ring 621 are limited to the outside of the central tube sleeve 4212. At the same time, it can be flexibly offset to a certain extent to adjust the bottom center of gravity of the buffer and reinforcement integrated structure composed of the upper fixed ring 61, the anti-breakage correction rod 6, and the movable counterweight ring 62. It is corrected by the vibration and swaying of the ceramic fiber filter tube 5. The ash trough 4213 mainly serves to remove ash.

[0021] Example 2 Please see Figures 6 to 9 Based on Embodiment 1, in order to increase the buffering effect on the ceramic fiber filter tube 5, this embodiment also proposes that the lower surface of the lower sleeve 42 is fixedly installed with a bottom cover 43 by bolts, the upper surface of the bottom cover 43 is evenly provided with ash discharge grooves 431, the middle of the upper surface of the bottom cover 43 is fixedly installed with a spherical bearing seat 432, the inside of the spherical bearing seat 432 is movably installed with a support shaft 63, the support shaft 63 is set in the middle of the inner side of the movable counterweight ring 62 and the central tube sleeve 4212, the upper surface of the support shaft 63 is fixedly installed with a spring telescopic sleeve rod 631, the upper end of the spring telescopic sleeve rod 631 is fixedly installed with an anti-slip support seat 632, and the upper surface of the anti-slip support seat 632 is in contact with the bottom surface of the ceramic fiber filter tube 5; In this embodiment, the bottom cover 43 mainly serves to install the spherical bearing seat 432, which in turn mainly serves to install the support shaft 63. The support shaft 63, through the cooperation of the spherical bearing seat 432, can adaptively deflect according to the oscillation and sway of the ceramic fiber filter tube 5. The spring telescopic sleeve 631 and the anti-slip support seat 632 mainly provide elastic support for the bottom of the ceramic fiber filter tube 5 and also serve as a buffer to reduce the adverse effects of vibration on the bottom of the ceramic fiber filter tube 5 during backwashing. The ash discharge trough 431 mainly serves to discharge ash.

[0022] Example 3 Please see Figures 16-17 Based on Embodiment 2, in order to correct the swaying of the ceramic fiber filter tube 5, this embodiment further proposes that an adjusting lever 64 be rotatably installed in the middle of the inner surface of the lower sleeve 42, the upper end of the adjusting lever 64 be in contact with the outer surface of the support shaft 63, the lower end of the adjusting lever 64 be in contact with the outer surface of the side pressure plate 622, and a spring return hinge rod 641 be rotatably installed on the upper outer surface of the adjusting lever 64. The other end of the spring return hinge rod 641 is rotatably connected to the inner surface of the lower sleeve 42. In this embodiment, in order to ensure that the adjusting lever 64 can be squeezed when the support shaft 63 deflects, this embodiment further proposes that a fan-shaped magnetic block 642 be hinged to the upper end of the adjusting lever 64, and the outer surface of the contact position between the support shaft 63 and the fan-shaped magnetic block 642 be made of magnetic material. The magnetic adsorption principle is used to ensure that the upper end of the adjusting lever 64 is in contact with the outer surface of the support shaft 63. In this embodiment, the support shaft 63 works in conjunction with the oscillation and swing of the ceramic fiber filter tube 5 to deflect it. When the ceramic fiber filter tube 5 swings to one side, the support shaft 63 will correspondingly deflect to that side. At this time, the support shaft 63 will push and squeeze the upper part of the adjusting lever 64 on the corresponding side. The adjusting lever 64 rotates around the center, and the bottom of the adjusting lever 64, according to the lever principle, will exert a certain reverse squeezing and pushing on the inner side pressure plate 622, causing the movable counterweight ring 62 to shift and adjust to a certain extent towards the opposite side of the swaying of the ceramic fiber filter tube 5. This adjusts the bottom center of gravity, preventing excessive gravity on the swaying side from causing the ceramic fiber filter tube 5 to break in the middle. Furthermore, the degree of adjustment of the adjusting lever 64 is determined by the degree of swaying of the ceramic fiber filter tube 5, achieving adaptive and precise adjustment. Furthermore, when the movable counterweight ring 62 shifts to the opposite side of the ceramic fiber filter tube 5, it will cause a certain degree of torsion in the anti-breakage correction rod 6 with the cooperation of the upper fixed ring 61 and the upper cover ring 611. The shift of the movable counterweight ring 62 to the opposite side of the ceramic fiber filter tube 5 will pull the anti-breakage correction rod 6 on the side of the ceramic fiber filter tube 5 to twist and correct the swaying posture of the ceramic fiber filter tube 5, helping the ceramic fiber filter tube 5 to reset. After the ceramic fiber filter tube 5 is reset, the spring reset hinge rod 641 will help the adjusting lever 64 to reset, and the reset spring 6221 will help the movable counterweight ring 62 to reset as a whole. It should be noted that this swaying correction process is not necessarily completed in one go; multiple back-and-forth corrections are required for the back-and-forth swaying.

[0023] Example 4 Please see Figures 1 to 17 Based on Embodiment 3, this embodiment also proposes a method for using a reinforced ceramic filter tube device, including the following steps: Step 1: Install the ceramic fiber filter tubes 5. The top cover 3 encapsulates the four sets of ceramic fiber filter tubes 5 independently inside the reinforced cover consisting of the upper sleeve 41, the reinforcing cage 4, and the lower sleeve 42. The four sets of ceramic fiber filter tubes 5 are fixedly installed between the tube sheet 1 and the pressure plate 2. Ceramic gaskets 11 are used in the middle to increase the seal. Bolts 13 and spacing sleeves 12 are used to fix the tube sheet 1 and the pressure plate 2, so that the four sets of ceramic fiber filter tubes 5 form an integrated filter structure. Finally, the integrated filter structure is fixedly installed inside the filter. Step 2: Under normal conditions, the side support pad 6112 maintains contact with the upper side surface of the ceramic fiber filter tube 5 under the action of the spring. The upper fixed ring 61, the ceramic fiber filter tube 5, and the movable counterweight ring 62 form an integrated buffer and reinforcement structure, maintaining a vertical state. The support shaft 63, the spring telescopic sleeve 631, and the anti-slip support seat 632 also maintain a vertical state. At this time, the ceramic fiber filter tube 5 can filter dust in the flue gas normally, and the dust will accumulate on the outside of the ceramic fiber filter tube 5. Step 3: When the ceramic fiber filter tube 5 is backwashed or shakes due to excessive dust, the spring of the spring slide 6111 will be squeezed, causing the corresponding side support pad 6112 to slide along the upper cover ring 611, which will buffer the ceramic fiber filter tube 5 and prevent the upper end of the ceramic fiber filter tube 5 from breaking rigidly. Step four: The support shaft 63, through the cooperation of the spherical bearing 432, can adaptively deflect according to the oscillation and swaying of the ceramic fiber filter tube 5. When the ceramic fiber filter tube 5 sways to one side, the support shaft 63 will deflect accordingly to that side. At this time, the support shaft 63 will push and squeeze the upper part of the adjusting lever 64 on the corresponding side. The adjusting lever 64 rotates around the center, and the bottom of the adjusting lever 64 will exert a certain reverse squeezing and pushing on the inner side pressure plate 622 according to the lever principle, so that the movable counterweight ring 62 is oriented in the same direction. The ceramic fiber filter tube 5 sways to the opposite side, causing a certain degree of displacement. This adjusts the bottom center of gravity to prevent excessive weight on the swaying side from causing the ceramic fiber filter tube 5 to break in the middle. With the cooperation of the upper fixing ring 61 and the upper cover ring 611, the anti-breakage correction rod 6 is twisted to a certain degree. The movable counterweight ring 62 moves towards the opposite side of the swaying ceramic fiber filter tube 5, which pulls the anti-breakage correction rod 6 on the swaying side of the ceramic fiber filter tube 5 to twist and correct the swaying posture of the ceramic fiber filter tube 5, helping the ceramic fiber filter tube 5 to return to its original position.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
