Description

Technical Field

[0001] This utility model relates to the field of carbon black production technology, specifically to a pulse-type carbon black bag filter. Background Technology

[0002] In downstream applications such as carbon black production, rubber, and chemicals, dust-laden gases exhibit harsh operating conditions characterized by wide particle size distribution, large specific surface area, easy aerosol formation, large temperature fluctuations, high moisture content, and strong dust adhesion. Traditional baghouse dust collection technology faces multiple technical bottlenecks: mechanical vibration cleaning suffers from rapid energy decay, large cleaning blind spots, and short filter bag life; traditional technologies have low energy efficiency ratios, high energy consumption for pulse valve opening and closing, and lack effective methods for handling sticky dust. More importantly, existing equipment lacks a technical solution that integrates electromagnetic force drive with the filter bag cleaning process, making it difficult to achieve precise control of the cleaning components. Therefore, developing a dust collection technology that combines high-efficiency cleaning, low energy consumption, and long filter bag life has become an urgent industry need. While existing technologies may already offer solutions to the above problems, this project aims to provide an alternative or replacement solution. Summary of the Invention

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a pulse-type carbon black bag filter, comprising: a filter cone box, a filter structure, and a dust removal structure, wherein the filter structure and the dust removal structure are installed inside the filter cone box, and the dust removal structure includes: a pair of filter plates, multiple expansion annular air bladders, multiple toothed diversion pipes, toothed siphon pipes, multiple J-shaped siphon pipes, an air pump, multiple toothed exhaust pipes, multiple lifting insert pipes, a well-shaped lifting bracket, two pairs of adsorption electromagnets, two pairs of adsorption magnets, two pairs of electromagnetic telescopic locks, a three-way valve, and a pulse pump; A pair of filter plates are installed inside the filter cone box. Multiple expansion annular airbags are evenly installed between the pair of filter plates. Multiple toothed diverter pipes are installed between the pair of filter plates and connected to the multiple expansion annular airbags respectively. A toothed siphon pipe is installed in the filter cone box. Multiple J-shaped siphon pipes are evenly inserted into the toothed siphon pipe and connected to the multiple toothed diverter pipes respectively. An air pump is connected to the toothed siphon pipe. The exhaust pipes are evenly inserted into the top of the filter cone box, and multiple lifting insertion pipes are movably inserted into the inner side of multiple toothed exhaust pipes. The well-shaped lifting bracket is fitted onto multiple lifting insertion pipes. Two pairs of adsorption electromagnets are installed on the filter cone box, two pairs of adsorption magnets are installed on the well-shaped lifting bracket, two pairs of electromagnetic telescopic locks are installed on the filter cone box, the three-way valve is installed on the toothed siphon pipe, and the pulse pump is installed on the three-way valve. It should be noted that, in the above process, the dust-laden gas enters the filter cone box, and the carbon black particles are intercepted by the filter bags, thus collecting the dust. Two pairs of electromagnets are energized, causing them to magnetically repel two pairs of magnets. These magnets then drive a well-shaped lifting bracket to rise and fall stably. The lifting bracket, in turn, drives multiple lifting inserts, inserting them into the filter structure. An air pump inflates the toothed siphon tubes, directing the high-pressure gas to the inside of multiple J-shaped siphon tubes. The J-shaped siphon tubes inflate the toothed diverter tubes, which in turn inflates multiple expanding annular air chambers. This expansion of the annular air chambers compresses the filter structure in the filter cone box, thus achieving external expansion and dust removal of the filter components through reverse inflation of the filter cone box.

[0004] Preferably, the filter structure includes: multiple limiting arc plates, multiple filter bags, and multiple fixing rings; Multiple limiting arc plates are mounted on the bottom filter plate, multiple fixing rings are respectively mounted on the multiple limiting arc plates, and multiple filter bags are respectively mounted on a pair of filter plates, multiple fixing rings and multiple limiting arc plates; It should be noted that, as described above, the filter bag is supported by the cooperation of the limiting arc plate and the fixing ring, and the filter bag is cleaned by the inner expansion.

[0005] Preferably, multiple pressure sensors are provided on the inner side of the filter cone box.

[0006] Preferably, the filter cone box is provided with an air inlet pipe, an exhaust pipe, and a discharge pipe.

[0007] Preferably, the well-shaped lifting support is provided with a slider assembly, and the inner side of the filter cone box is provided with a slide rail assembly.

[0008] Preferably, the well-shaped lifting support has a limiting hole. Beneficial effects

[0009] This utility model provides a pulse-jet carbon black bag filter. Compared with existing technologies, this pulse-jet carbon black bag filter offers the following advantages: First, it employs a magnetically driven lifting system, utilizing the repulsive action of electromagnets and permanent magnets to achieve millimeter-level precise lifting of the well-shaped support, ensuring flexible connection between the lifting insert and the filter bag and avoiding mechanical impact damage. Second, it features a unique composite cleaning mechanism, combining the radial expansion of the airbag (generating a uniform pressure of 5 kPa) with the dual effects of pulse airflow backflushing (0.7 MPa instantaneous impact), improving cleaning efficiency by over 40%. Third, it integrates an intelligent differential pressure management system, using multi-point pressure sensors to monitor filter bag resistance in real time and automatically matching three levels of cleaning intensity, extending filter bag life to over 3 years. Finally, it adopts an energy-efficient optimization design, using a magnetic system energy recovery circuit to recharge braking energy back to the supercapacitor, combined with a pulse valve segmented pressurization control strategy, achieving a comprehensive system energy efficiency ratio of 85%, saving over 30% energy compared to traditional equipment, making it particularly suitable for industrial purification scenarios involving high-concentration, sticky carbon black dust.
