Description

Sintering filter cylinder

Technical Field

The utility model belongs to the technical field of filtering material and specifically relates to a section of thick bamboo is strained in sintering.

Background

The plastic sintered filter element which is technically characterized by the ultra-high molecular weight polyethylene sintered porous base material and the polytetrafluoroethylene surface microporous coating is gradually known all over the world since the invention of Germany in the last 70 th century; the plastic sintered filter material can be made into corrugated plate type filter elements (called sintered plate filter elements or sintered plate filter elements) or corrugated cylindrical filter elements (called plastic sintered filter cylinders). Due to the characteristics of extremely high filtering efficiency, abrasion resistance, strong moisture resistance, ultra-long service life and the like, the plastic sintered filter elements are gradually exposing the corners in the blue sky defense war of ultra-low particulate matter emission in various industries.

Because the size of the interface of the plastic sintering filter cylinder is the same as that of the filter bag of the bag-type dust collector, and the processing air volume of each filter cylinder is basically the same as that of the filter bag, the filter bag can be directly replaced, the original bag-type dust collector is upgraded and modified into the sintering filter cylinder dust collector, and the modification cost is greatly reduced on the premise of meeting the strict environmental-protection emission standard.

Because the diameter of the inner cavity of the plastic sintered filter cylinder is larger, and all folds are in the same inner cavity, the rigidity is very poor, the resistance during filtering and the back-blowing pressure during ash removal can cause local large-size shrinkage or expansion of the folded filter material, so that the filter material is quickly fatigue-damaged, and the reinforcement is needed. The prior art is provided with an inner lining and an external hoop. The dust is easily accumulated at the position of the hoop by the external hoop; the fiber is easy to be roughened under the working condition of abrasive dust, and the fiber falls off to pollute materials; the hoops are scratched and rubbed to easily fall off, and even bottom ash discharging equipment is plugged. The whole filter cylinder is supported by the lining, but in the back flushing process, the whole filter cylinder is supported, so that local vibration cannot be generated, the ash cleaning effect is not obvious, and the filtering effect of the filter cylinder is influenced.

For example, chinese patent publication discloses "a sintered filter cartridge provided with a reinforcing liner", which is under the publication number CN 206934967U; the patent discloses a sintered filter cylinder with a reinforced lining, which comprises a filter element, a seal tail and a seal head, wherein the cross section of the filter element is in a quincunx shape, a cylindrical lining is arranged in the filter element, the lining is in interference fit with the filter element, and a plurality of air holes are formed in the surface of the lining; the length of inside lining is greater than the length of filter core, and the inside lining both ends are equipped with the installation screw thread, seal the tail and install in the both ends of filter core through adding screw thread and sealing washer with the head. In the patent, the lining is in interference fit with the filter element, so that the strength is ensured, but during backwashing, the whole filter element is fixed, so that the vibration amplitude is small or zero, the backwashing is not facilitated, and the filtering effect of the filter element is further influenced; holes are formed in the lining, and the filter element is blocked at the position where the holes are not formed in the lining, so that the filtering effect is influenced; the lining penetrates through the whole filter element, so that the whole weight is increased, and the installation and later maintenance and repair are not facilitated.

The arrangement distance of the built-in hoops depends on the mechanical strength and the maximum running resistance of the filter material, and is determined according to the actual use condition, so that the strength is ensured, and the filtering efficiency is ensured; the parallel arrangement ensures that all parts are stressed uniformly, the service life is ensured, and the filter element structure cannot be damaged due to uneven stress; the arrangement is inside, can not produce the deposition, also can not appear wearing and tearing in the use and produce impurity, can not influence other part work.

Further, the hoop is annular and is abutted to the inner wall. The installation is simple and convenient.

Furthermore, the periphery of the hoop is provided with a notch matched with the inner wall. The breach can have spacing effect, evenly separates each fold, has guaranteed the stability of structure, and can not produce deformation or several folds extrusion when receiving the exogenic action together to influence filtration efficiency.

Further, the hoop is fixedly connected to the inner wall; the fixed connection is ultrasonic welding or structural adhesive bonding. The connection mode is determined according to the actual use condition, the device is flexible and multipurpose, and the service life is ensured by fixed connection.

Furthermore, the hoop is made of nylon, polypropylene or polyethylene. The material that selects for use according to waiting to filter the material has better suitability, has increased life, has practiced thrift the cost.

Compared with the prior art, the utility model has the advantages that: the filter effect is good, the back washing is not influenced, the dust is not easy to accumulate, and the fiber pollution to materials is not generated; and the whole quality is controllable, and the later maintenance and repair are facilitated.
