Description

Technical Field

[0001] This utility model relates to the field of fiber filter cartridge manufacturing technology, and in particular to a connecting fiber filter cartridge. Background Technology

[0002] Fiber filter cartridges are the core filtration unit of integrated dust and nitrification ultra-clean technology, a major environmental protection technology and equipment encouraged by the state. In recent years, they have been increasingly widely used in flue gas treatment in industries such as thermal power, metallurgy, coking, and glass kilns. Currently, the mainstream filter cartridge specification in China is 3 meters in length. Some filter cartridge manufacturers have launched filter cartridges with a length of 4 meters, but due to cost issues, they cannot be used on a large scale.

[0003] Currently, the mainstream filter cartridge length in China is 3 meters. This results in a large footprint and high initial investment for projects with large flue gas volumes. For companies with limited space, this leads to design difficulties and high operational risks. To reduce the footprint, more and more companies are launching filter cartridges of 4 meters or even longer. However, longer cartridges are more difficult to manufacture, have inconsistent quality, leading to high costs, increased transportation and installation difficulties, and reduced overall economic efficiency. Furthermore, fiber filter cartridges primarily operate in high-temperature environments. If the clean air chamber cover uses a split structure, it cannot guarantee the equipment's insulation effect, affecting heat recovery, wasting resources, and even causing excessively low flue gas temperatures that prevent normal equipment operation. To ensure normal operation and heat recovery efficiency, most companies use an integrated cover, with the filter cartridge inserted into the clean air chamber through a manhole at the top. The disadvantage of this structure is that the height of the clean air chamber must be greater than the length of the filter cartridge for installation, increasing installation difficulty and initial investment. The longer the filter cartridge, the more pronounced the drawbacks of this structure become, making transportation inconvenient.

[0004] Therefore, we propose a connecting fiber filter cartridge to solve the above problems. Utility Model Content

[0005] In order to solve the above-mentioned problems existing in the prior art, this utility model provides a connecting fiber filter cartridge.

[0006] The technical solution of this utility model is as follows:

[0007] A connecting fiber filter cartridge includes a flange base section and a tail end base section. The upper end of the flange base section is a filter cartridge mounting flange, and the lower end is a cylindrical opening. The upper end of the tail end base section is a cylindrical opening, and the lower end is a hemispherical closed end. The flange base section and the tail end base section are connected together by a rotary joint fixed at the connection point to form a whole. Locking rings are fitted at the lower end of the flange base section and the upper end of the tail end base section at the cylindrical opening, and the locking rings are threadedly connected to the rotary joint. The rotary joint is provided with a groove and a locking plate, and a sealing gasket is provided at the mating position. The lower end is a V-shaped opening, the middle is provided with a fixing thread, and the interior is provided with a positioning shoulder.

[0008] Preferably, the upper 200mm region of the flange end and the lower 100mm region of the circular opening end of the flange base are coated with silica sol.

[0009] Preferably, the upper cylindrical opening area (200mm) and the lower hemispherical closed area (100mm) of the tail end base are coated with silica sol.

[0010] Preferably, the upper part of the locking ring is circular, the inner wall is threaded, and the lower end is V-shaped.

[0011] Preferably, the mating end faces of the flange base tube and the tail end base tube are provided with anti-rotation limiting grooves, which cooperate with the positioning protrusions inside the rotary joint.

[0012] Preferably, the sealing gasket is made of fluororubber material and has a double-protrusion structure in cross section, which is respectively embedded in the mating end face of the flange base and the tail end base.

[0013] This invention offers the following advantages: By manufacturing the filter cartridge in segments, with each segment connected and fixed via a rotary joint secured by a locking ring, the flange base section and the tail end base section are connected together using the rotary joint to form a single unit. Installation simply involves rotating the rotary joint to engage the upper and lower slots with the locking plate, followed by compression of the sealing ring to achieve a seal. The entire installation process is quick, efficient, and rapid. Segmented transportation, with each segment equipped with a connecting mechanism, allows for filter cartridge connection and installation within the clean air chamber, effectively extending the filter cartridge's length. This solves the problems of difficult production, transportation, and installation of long filter cartridges. Attached Figure Description

[0032] The working principle of this utility model:

[0033] In this utility model, the upper end of the flange base cylinder 1 is a filter cartridge mounting flange, and the lower end is a cylindrical opening; the upper end of the tail base cylinder 2 is a cylindrical opening, and the lower end is a hemispherical closed end; the flange base cylinder 1 and the tail base cylinder 2 are connected together by a rotary joint 3 fixed at the connection point; the mating end faces of the flange base cylinder 1 and the tail base cylinder 2 are provided with anti-rotation limiting grooves, which cooperate with the positioning protrusions inside the rotary joint 3 to form an integral whole; the lower end of the flange base cylinder 1 and the tail base cylinder 2... A locking ring 4 is fitted at the upper cylindrical opening. The upper part of the locking ring 4 is circular with threads on the inner wall and a V-shaped opening at the lower end. The locking ring 4 is threadedly connected to the rotary joint 3. The rotary joint 3 is provided with a groove and a plate, and a sealing gasket 31 is provided at the mating position. The lower end is a V-shaped opening, and a fixing thread is provided in the middle. A positioning shoulder is provided inside. The sealing gasket 31 is made of fluororubber material and has a double boss structure in cross section. It is embedded in the mating end face of the flange base cylinder 1 and the tail end base cylinder 2 respectively.

[0034] In use, the locking ring 4 is fitted into the lower cylindrical opening of the flange base cylinder 1, and then the rotary connector is fitted into the lower cylindrical opening of the flange base cylinder, stopping when it reaches the positioning shoulder. The locking ring is then screwed into the rotary connector 3 through the threaded connection. The V-shaped opening at the lower end of the locking ring 4 presses against the V-shaped opening at the lower end of the rotary connector 4. Under the pressure, the V-shaped opening of the rotary connector 4 holds the filter cartridge tightly and fixes it at the lower cylindrical opening of the flange base cylinder 1. The rotary connector 3 is fixed to the upper cylindrical opening of the tail base cylinder 2 in the same way.

[0035] During installation, the flange base cylinder 1 and the tail end base cylinder 2 are connected together by a rotary joint 3 fixed on them to form a whole. Installation simply requires rotating the rotary joint to connect the upper and lower slots with the clamping plate, and the sealing ring is compressed to complete the seal. The entire installation process is quick, efficient, and fast. Furthermore, in this invention, silica sol is used to reinforce the 200mm area at the upper flange end and the 100mm area at the lower circular opening end of the flange base cylinder 1; similarly, silica sol is used to reinforce the 100mm area at the upper cylindrical opening end and the 100mm area at the lower hemispherical closed end of the tail end base cylinder 2, thereby improving the stability of the device.
