Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a dust collector filter tube structure. Background Technology

[0002] In modern industrial production, dust collectors are becoming increasingly common, helping to remove dust and particulate matter from the air to protect the environment and worker health. While traditional baghouse dust collectors can meet dust removal needs to some extent, they have limitations, such as the high frequency of bag replacement and high maintenance costs. Therefore, filter tubes are increasingly being used to replace baghouse dust collectors.

[0003] The emergence of filter tube technology has brought new solutions to industrial dust removal. Compared with traditional baghouse dust collectors, filter tubes have higher filtration efficiency and longer service life. They are typically made of high-temperature and corrosion-resistant materials, enabling them to adapt to various harsh working environments. Furthermore, the replacement and maintenance of filter tubes are simpler and faster, significantly reducing operating costs and downtime.

[0004] Currently, the filter tubes in dust collectors are suspended and fixed to the tube sheet. However, this traditional installation method faces several challenges in practical applications. When subjected to severe vibrations, especially in high-vibration industrial environments, the filter tubes need to withstand periodic vibrations and impacts. Furthermore, in areas prone to typhoons and earthquakes, the filter tubes are subjected to strong vibrations caused by unforeseen external forces. Therefore, structural stability becomes a critical issue. Loosening at the connection between the filter tube and the tube sheet can easily lead to the filter tube shaking, causing collisions and damage between the tubes, and even potentially causing them to detach, resulting in production accidents.

[0009] The upper surface of the support cup has a contoured groove that matches the tail of the filter tube. The tail of the filter tube is located in the contoured groove. A bolt is fixedly installed at the bottom of the support cup. The lower end of the bolt passes through the fixed bracket and is threadedly connected to a nut located below the fixed bracket. A washer is provided between the nut and the fixed bracket.

[0010] The buffer spring is disposed between the support cup and the fixed bracket.

[0011] In some embodiments, a pressure plate is also provided at the top of the filter tube, and the pressure plate is connected to the tube sheet by bolts.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Example 1:

[0029] like Figure 1 and 2As shown, this embodiment discloses a dust collector filter tube structure; specifically, the filter tube structure includes a filter tube 1, a fixed bracket 7, a support cup 5, and two buffer springs 8; the filter tube 1 can be a metal filter tube, a silicon carbide filter tube, a ceramic fiber filter tube, etc.; a tube sheet 2 is fixedly installed on the upper side inside the dust collector, and the head of the filter tube 1 is suspended and fixed on the tube sheet 2. A pressure plate 3 is provided at the head of the filter tube 1, and the pressure plate 3 is connected to the tube sheet 2 by a first bolt 4, thereby pressing and fixing the head of the tube; the fixed bracket 7 is fixedly installed inside the dust collector and located below the filter tube 1; the upper surface of the support cup 5 has a contoured groove adapted to the tail of the filter tube 1, and the filter tube... The tail of the filter tube 1 is set in the contour groove. The bottom of the support cup 5 is fixedly provided with a second bolt 9. The lower end of the second bolt 9 passes through the fixed bracket 7 and is threadedly connected to two nuts 10 located below the fixed bracket 7. A washer is provided between the nut 10 located close to the lower surface of the fixed bracket 7 and the fixed bracket 7. The two buffer springs 8 are set between the support cup 5 and the fixed bracket 7 and are symmetrically arranged on both sides of the second bolt 9. The two ends of the buffer springs 8 are respectively connected to the support cup 5 and the fixed bracket 7. The buffer springs 8 are used to further absorb and buffer external impact forces and reduce the vibration of the filter tube 1. Specifically, the buffer springs 8 are of the type of coil spring, which has good elasticity and durability.

[0030] In this embodiment, the design of the aforementioned support cup 5 is to ensure that the tail of the filter tube 1 can be stably placed on it. By manufacturing a support cup 5 that conforms to the specific shape of the bottom of the filter tube 1, the filter tube 1 can be effectively supported, ensuring that it will not tilt or shake due to vibrations caused by uncontrollable factors such as earthquakes or typhoons during use. This design improves the stability of the filter tube 1. The adaptability of the support cup 5 allows the filter tube 1 to be tightly embedded on it, thereby maintaining stability during filtration and avoiding unnecessary shaking caused by vibration or external forces. In addition, this adaptability design also helps to extend the service life of the filter tube 1, as it can reduce internal structural damage or breakage caused by vibration or collisions between filter tubes 1. In summary, by precisely manufacturing the support cup 5 with a conforming groove that conforms to the shape of the tail of the filter tube 1, the filter tube 1 can be effectively supported, ensuring its stability and reliability in various usage environments.

[0031] The aforementioned support cup is made of carbon steel or stainless steel. Under the elastic action of the buffer spring 8, the support cup 5 can deform accordingly according to the vibration amplitude of the filter tube 1, thereby achieving dynamic support for the filter tube 1. In addition, an anti-slip and shock-absorbing pad 6 is provided between the support cup 5 and the filter tube 1. The anti-slip and shock-absorbing pad 6 serves two purposes: firstly, it prevents relative sliding between the filter tube 1 and the support cup 5 during vibration, ensuring the stability of the filter tube 1; secondly, it absorbs and disperses external impact forces, reducing the direct impact on the filter tube 1; and thirdly, the anti-slip and shock-absorbing pad 6 is made of materials with good elasticity, durability, and high temperature resistance, such as ceramic fiber or rock wool.

[0032] The aforementioned fixing bracket 7 is used to support the cup 5 to fix the tail of the filter tube 1 in a proper position, preventing it from shifting or falling off when subjected to external impact. This fixing bracket 7 is typically made of high-strength material to ensure its stability and durability. Specifically, the fixing bracket 7 is an L-shaped steel or channel steel, and both ends of the fixing bracket 7 are welded to the inner wall of the dust collector.

[0033] Through the coordinated operation of the above components, filter tube 1 can be effectively protected from external vibration and impact, ensuring its normal operation and extending its service life. It is suitable for filter tube equipment in various industrial and civil fields and has broad application prospects.

[0034] Example 2:

[0035] like Figure 3 As shown, the structure of the dust collector filter tube in this embodiment is roughly the same as that in the first embodiment above. The only difference is that the dust collector filter tube structure in this embodiment is equipped with only one buffer spring 8. The buffer spring 8 is located between the support cup 5 and the fixed bracket 7 and is sleeved on the second bolt 9. In this embodiment, only one spring is required to provide good buffering and shock absorption for the filter tube 1. The buffer spring 8 can be sleeved on the second bolt 9 without additional fixing.
