Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature dust collectors, specifically relating to a protective device for a pleated high-temperature resistant filter cartridge. Background Technology

[0002] Industrial flue gas is a major air pollutant, characterized by high humidity, strong corrosiveness, and high dust concentration. In flue gas treatment, cartridge dust collectors are gradually becoming the preferred upgrade and replacement for traditional baghouse dust collectors, and are increasingly used in the dust removal industry both domestically and internationally. Among them, high-temperature pleated dust collectors offer advantages such as larger filter area, reduced filtration velocity, increased flue gas throughput, and convenient installation, effectively addressing flue gas environments in industrial settings.

[0003] The pleated structure of high-temperature dust collectors can efficiently capture fine particulate matter from flue gas. However, the adhesion of dust and the pleated structure of the filter cartridge increase the depth of dust deposition. To ensure the normal operation of the filter cartridge dust collector, the accumulated dust needs to be removed.

[0004] Currently, the most common solution for dealing with dust accumulation in pleated dust collectors is pulse jet cleaning. To ensure the dust removal efficiency of pleated dust collectors, high-pressure pulse jet cleaning is required. However, when the pulse jet pressure is too high, the pleated structure of the filter media will change, leading to a decrease in effective filtration area and filtration efficiency, which severely restricts the service life of the filter cartridge. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for a pleated high-temperature resistant filter cartridge, in order to solve the technical defects of existing pleated high-temperature resistant filter cartridges, which are prone to structural changes under large pulse jet pressure, resulting in a decrease in effective filtration area, a reduction in filtration efficiency, and an impact on the service life of the filter cartridge.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective device for a pleated high-temperature filter cartridge includes a protective component disposed on the outer surface of the high-temperature pleated filter cartridge body, with latches at both ends for connection, and a steel ring for reinforcement on the surface of the protective component.

[0008] The protective component includes a rubber strip that is sleeved on the outer surface of the high-temperature pleated filter cartridge body and distributed circumferentially along the body. The inner side of the rubber strip has several teeth that are evenly distributed in a ring.

The inner cavity of the rubber strip is provided with a steel wire, a buckle is provided on the steel wire, and a steel ring is fixedly sleeved on the outer surface of the rubber strip.

[0009] As a further embodiment of this utility model, a steel wire is embedded through the inside of the rubber strip, and grooves are provided on the outer sides of both ends of the rubber strip. The ends of the steel wires are all inserted into the grooves and connected by a locking buckle.

[0010] As a further embodiment of this utility model, the circumference of the steel wire is twice the circumference of the rubber strip, and the steel wire is located in the groove with a U-shaped redundant structure, and the buckle is located at the two U-shaped redundant parts of the steel wire.

[0011] As a further embodiment of this utility model, the tip of the tooth is arc-shaped, and the tooth and the high-temperature pleated filter cartridge body are concentrically arranged.

[0012] As a further embodiment of this utility model, the tooth height is 20% of the depth of the tooth groove of the high-temperature pleated filter cartridge body, and the distance between the two sides of the inner wall of the groove is 7.54mm.

[0013] As a further embodiment of this utility model, the teeth and the high-temperature pleated filter cartridge body are fixedly connected by hot melt adhesive, and the steel ring is welded and fixed to the protective component.

[0014] As a further embodiment of this utility model, two steel rings are provided on the surface of the rubber strip along its axial direction, and the locking buckle is located between the two steel rings.

[0015] As a preferred embodiment of this utility model, the surface of the steel wire located in the U-shaped redundant structure inside the groove is sprayed with anti-corrosion coating for steel structures.

[0016] Compared with the prior art, the protective device for a pleated high-temperature resistant filter cartridge provided by this utility model has the following beneficial effects:

[0017] This device uses steel wire embedded in rubber strips to enhance the rigidity and strength of the rubber strips, thereby effectively reducing the impact of high-frequency material impact and mechanical vibration caused by pulse jet blowing, and maintaining the stable operation of the high-temperature filter cartridge. The steel wire ring reserved on the outside of the rubber strip is coated with anti-corrosion paint, which can effectively avoid the impact of high temperature, high humidity and acid and alkali corrosion on the steel wire in the working conditions. Hot melt adhesive is applied to the surface of the high-temperature filter cartridge filter material, and a certain pressure is used to press the filter cartridge and rubber strip bundle together for positioning and fixation. The steel ring around the outside of the protective device plays a fixing and protection role, ensuring the structural integrity of the high-temperature pleated filter cartridge body, so that the high-temperature pleated filter cartridge body can filter stably, thereby ensuring the filtration area and filtration efficiency of the high-temperature pleated filter cartridge body and extending the service life of the high-temperature pleated filter cartridge body.

[0031] See appendix Figures 1-4 As shown in the figure, a protective device for a pleated high-temperature resistant filter cartridge according to an embodiment of the present invention includes a protective component 100 disposed on the outer surface of the high-temperature pleated filter cartridge body 1, a locking buckle 200 for connection, and a steel ring 300 for reinforcement. The locking buckle 200 is disposed between the two ends of the protective component 100, and the steel ring 300 is disposed on the surface of the protective component 100.

[0032] The protective component 100 includes a rubber strip 110 that is sleeved on the outer surface of the high-temperature pleated filter cartridge body 1 and distributed circumferentially along the high-temperature pleated filter cartridge body 1. The inner side of the rubber strip 110 is integrally formed with a number of teeth 120 that are distributed in a ring at equal intervals. The teeth 120 are arranged in a one-to-one correspondence with the tooth grooves of the high-temperature pleated filter cartridge body 1, and each tooth 120 is inserted into the corresponding tooth groove of the high-temperature pleated filter cartridge body 1. The inner cavity of the rubber strip 110 is provided with a steel wire 130, a buckle 200 is provided on the steel wire 130, and a steel ring 300 is fixedly sleeved on the outer surface of the rubber strip 110.

[0033] In order to ensure that the rubber strip 110 is stably formed into a ring structure on the surface of the high-temperature pleated filter cartridge body 1, the circumference of the steel wire 130 is twice that of the rubber strip 110, and the steel wire 130 is located inside the groove 140 with a U-shaped redundant structure. The locking buckle 200 is attached to the two U-shaped redundant parts of the steel wire 130. Through the special structural design of the steel wire 130, while improving the overall rigidity and strength of the rubber strip 110, the steel wire 130 end can also form a U-shaped redundant structure, which facilitates the quick installation and removal of the locking buckle 200 and provides pre-tightening force.

[0034] The tip of the tooth 120 is arc-shaped, and the tooth 120 and the high-temperature pleated filter cartridge body 1 are concentrically arranged.

[0035] The tooth height of tooth 120 is 20% of the tooth groove depth of the high-temperature pleated filter cartridge body 1, and the distance between the two sides of the inner wall of groove 140 is 7.54mm.

[0036] The tooth 120 is fixedly connected to the high-temperature pleated filter cartridge body 1 by hot melt adhesive, and the steel ring 300 is welded and fixed to the protective component 100.

[0037] In order to ensure the reinforcement and protection of the protective component 100 while avoiding interference between the latch 200 and the steel ring 300, two steel rings 300 are provided on the surface of the rubber strip 110 along its axial direction, and the latch 200 is located between the two steel rings 300.

[0038] To extend the service life of the steel ring 300, the surfaces of the steel ring 300 and the fusible redundant parts of the steel wire 130 are coated with anti-corrosion paint for steel structures. The anti-corrosion paint for steel structures can effectively avoid the effects of high temperature, high humidity and acid and alkali corrosion on the steel ring 300 and the fusible redundant parts of the steel wire 130 in the working conditions.

[0039] This utility model provides a protective device for a pleated high-temperature resistant filter cartridge, which consists of a protective component 100, a locking buckle 200, and a steel ring 300. The specific manufacturing process is as follows:

[0040] Curing and molding: A toothed strip 110 is obtained by using a mold through a glue injection method. A steel wire 130 is placed flat in the mold, avoiding the toothed part 120. A U-shaped structure is reserved at both ends of the strip 110. Then, glue is injected to obtain the protective component 100.

[0041] Anti-corrosion spraying: Spray the surface of the exposed rubber strip 110 and the U-shaped redundant part of the steel wire 130 located in the groove 140 with anti-corrosion coating for steel structures.

[0042] Adhesive fixing: Using an adhesive dispensing machine, hot melt adhesive is applied to the surface of the high-temperature pleated filter cartridge body 1. The teeth 120 are aligned with the grooves of the high-temperature pleated filter cartridge body 1, so that the teeth 120 are placed in the grooves of the high-temperature pleated filter cartridge body 1. A certain pressure is applied to press the high-temperature pleated filter cartridge body 1 and the teeth 120 together and fix them with hot melt adhesive. According to the actual height of the high-temperature pleated filter cartridge body 1, several independent protective components 100 are selected and arranged in parallel to form a bundle structure.

[0043] Snap-on connection: Snap the buckle 200 onto the two frustum-shaped redundant parts of the steel wire 130, so that the protective component 100 is stably fixed to the surface of the high-temperature pleated filter cartridge body 1 by the buckle 200.

[0044] Welding fixation: The steel ring 300 is fitted onto the surface of the rubber strip 110 and welded to the rubber strip 110, so that the steel ring 300 surrounds the outside of the protective component 100 to play a fixing and protection role.

[0045] To prevent the steel wire 130 from protruding from the outer surface of the rubber strip 110 and affecting the fixing operation of the steel ring 300, in this embodiment of the utility model, the steel wire 130 is embedded and passes through the interior of the rubber strip 110, and the outer sides of both ends of the rubber strip 110 are provided with grooves 140. The ends of the steel wire 130 pass through the grooves 140 and are connected by the buckle 200. The grooves 140 can provide a space for the ends of the steel wire 130 to ensure the flatness of the surface of the protective component 100.

[0046] In summary, in this embodiment of the present invention, the rubber strip 110 has the characteristics of buffering and shock absorption, weather resistance, durability, and resistance to compression deformation. When the high-temperature pleated filter cartridge body 1 is subjected to pulse jet cleaning, this protective device can support and protect the high-temperature pleated filter cartridge body 1. It can effectively solve the problem of damage to the pleated structure of the high-temperature pleated filter cartridge body 1 due to excessive pulse jet pressure during the cleaning process, ensure the structural integrity of the high-temperature pleated filter cartridge body 1, enable the high-temperature pleated filter cartridge body 1 to filter stably, and thus ensure the filtration area and filtration efficiency of the high-temperature pleated filter cartridge body 1, and extend the service life of the high-temperature pleated filter cartridge body 1.
