Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and more specifically, to a blowpipe structure for a bag filter. Background Technology

[0002] The blowpipe of a bag filter is an important component for cleaning dust from the surface of the filter bags. Its main function is to periodically blow high-pressure air into the filter bags to remove the dust accumulated on them, thereby restoring the air permeability and dust removal efficiency of the filter bags. Each row of filter bags in the filter chamber is equipped with a blowpipe at the top of the outlet. The blowpipe has a nozzle on its lower side facing the center of the filter bag. Each blowpipe is equipped with a pulse valve and is connected to the compressed air tank. During cleaning, the pulse valve is opened, and the compressed air is controlled by the cleaning control device (differential pressure or timed, manual control) according to the set program to open the electromagnetic pulse jet. The compressed gas passes through each pulse valve in sequence in a very short time and induces several times the amount of air injected into the filter bag through the nozzle on the blowpipe, forming an air wave. This causes the filter bag to expand and vibrate rapidly from the bag opening to the bottom, resulting in a strong cleaning effect and shaking off the dust on the filter bag.

[0003] In existing baghouse dust collectors, the nozzles of the blowpipe structure are aimed at the filter bags full of dust. When the blowing operation stops, the dust on the filter bags can easily drift into the nozzles, causing blockage at the nozzles and resulting in a decrease in blowing efficiency. In view of this, we propose a blowpipe structure for baghouse dust collectors. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a blowpipe structure for a bag filter to solve the technical problem of easy clogging of the blowpipe nozzles in the current bag filter.

[0024] like Figures 1 to 4 As shown, the present invention relates to a blowpipe structure for a bag filter dust collector, including a blowpipe 1, a mounting frame 2 installed at one end of the blowpipe 1, a plurality of blow nozzles 3 installed in a linear equidistant array on the blowpipe 1, the blow nozzles 3 being connected to the blowpipe 1, a mounting assembly 4 installed on the mounting frame 2, a plurality of one-way sealing components 5 installed in a linear equidistant array on the mounting assembly 4, the one-way sealing components 5 being able to correspond to the blow nozzles 3;

[0025] The one-way sealing component 5 includes a cover plate 501 that seals the opening of the nozzle 3. A hinge ring 503 is fixedly installed on the other end of the cover plate 501 and is hinged to the mounting component 4 through the hinge ring 503. A spring 506 is fixedly installed on the cover plate 501, and the other end of the spring 506 is detachably installed on the mounting component 4. Each nozzle 3 of this utility model is sealed with an independent one-way sealing component 5. During spraying, the one-way sealing component 5 is blown open to clean the dust. When not spraying, the one-way sealing component 5 automatically seals the nozzle 3 to prevent dust backflow. The one-way sealing components 5 are all independently installed on the mounting component 4, which facilitates quick disassembly, maintenance and replacement. In addition, the hinge ring 503 is hinged to the outside of the hinge frame 504 by designing an "L"-shaped hinge frame 504. The open end of the hinge frame 504 is sealed by a nut 505 connected by a thread. Damaged one-way sealing components 5 can be disassembled separately, which speeds up the maintenance and replacement.

[0026] Furthermore, the mounting bracket 2 includes a side bracket 201 fixedly mounted on one end of the blow pipe 1, and a ring seat 202 fixedly mounted on the side bracket 201 to facilitate the installation of the blow pipe 1.

[0027] Furthermore, the mounting assembly 4 includes a mounting rod 401 that is inserted into the ring seat 202, and a flange 402 is fixedly mounted on the other end of the mounting rod 401 to facilitate the installation of the mounting rod 401.

[0028] Furthermore, a sealing ring 502 is also installed on the cover plate 501. The sealing ring 502 can be matched with the nozzle 3. The sealing ring 502 is made of flexible rubber material. When the cover plate 501 seals the nozzle 3, it increases the sealing effect and further prevents dust from entering the nozzle 3.

[0029] Furthermore, several hinge brackets 504 are fixedly installed on the mounting rod 401 in a straight, equidistant array. The hinge brackets 504 are L-shaped, and a nut 505 is threaded to the other end of the hinge bracket 504. The hinge ring 503 is hinged to the outside of the hinge bracket 504 for easy installation or disassembly.

[0030] Furthermore, a clamp 507 is fixedly connected to the other end of the spring 506, and the clamp 507 is detachably mounted on the mounting rod 401 by bolts 508.

[0031] Furthermore, the blow pipe 1 has several parts and its ends are connected to the main pipe 6. The main pipe 6 is connected to the existing pulse valve and the existing compressed air manifold on the market, which facilitates the blow operation.

[0032] Working Principle: This embodiment provides a blowpipe structure for a bag filter dust collector. During use, each blowpipe 3 is sealed with an independent one-way sealing element 5. During blowing, the one-way sealing element 5 is blown open for dust removal. When not blowing, the one-way sealing element 5 automatically seals at the blowpipe 3 to prevent dust backflow. Each one-way sealing element 5 is independently installed on the mounting assembly 4, facilitating quick disassembly, maintenance, and replacement. Furthermore, an "L"-shaped hinge frame 504 is designed, with the hinge ring 503 hinged to the outside of the hinge frame 504. The open end of the hinge frame 504 is sealed by a threaded nut 505, allowing for individual removal of damaged one-way sealing elements 5, accelerating maintenance and replacement. When the blowpipe 1 is blowing for dust removal, the externally connected compressed air manifold... The air wave travels through the blowpipe 1 to the blow nozzle 3, and the impact vibration opens the cover plate 501 without hindering the dust removal work. At the same time, the hinge ring 503 at the other end of the cover plate 501 rotates on the "L"-shaped hinge frame 504. The cover plate 501 rotates downwards synchronously to expose the blow nozzle 3. The spring 506 is stretched. When the dust removal work is finished, the blow nozzle 3 no longer sprays air outwards. The spring 506 rebounds and resets, driving the cover plate 501 to reset, continuing to seal the blow nozzle 3. Dust is difficult to backflow, keeping the inside of the blow nozzle 3 clean and unobstructed. When it is necessary to disassemble and replace the one-way sealing part 5, first unscrew the nut 505 at the end of the "L"-shaped hinge frame 504, and then remove the clamp 507. The damaged one-way sealing part 5 can be quickly disassembled for repair and replacement.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
