Description

Technical Field

[0001] The utility model belongs to the field of dust removal filter bags, in particular to an improved dust removal filter bag. Background Art

[0002] Environmental protection is a broad area of ​​concern in the chemical industry. The purification and recovery of soot generated by smelting, crushing, screening, and combustion in steel mills, smelters, cement plants, carbon black plants, power plants, and other enterprises contributes to both air and dust pollution. Energy-saving improvements to meet emission standards and achieve environmental protection goals have become a pressing challenge for all companies.

[0003] The prior art has specially developed some improved dust filter bags. For example, the Chinese patent with the announcement number "CN114259805B" announced "An improved high-efficiency dust filter bag". By arranging a center rod that can move up and down and the upper and lower discs connected thereto in the cylindrical frame, it can be realized that when the filter bag is cleaned, intermittent high-pressure airflow presses down the upper disc, driving the center rod to drive the lower disc to press down. At the same time, under the cooperation of the compression spring and the tension spring, the upper disc rebounds after the downward pressure of the airflow, thereby realizing the up and down movement of the lower disc. Through the up and down movement of the lower disc, the filter bag body can be shaken during cleaning, so as to quickly shake off the dust accumulated on the filter bag body, so as to assist the reverse airflow to clean the filter bag body, thereby improving the cleaning efficiency during cleaning, reducing the elongation required for cleaning, reducing the power loss of the equipment, and having high practical value.

[0004] Although by arranging a center rod that can move up and down and the upper and lower discs connected to it in the cylindrical frame, when cleaning the filter bag, intermittent high-pressure airflow can press down the upper disc, driving the center rod to drive the lower disc to press down, and at the same time, with the cooperation of the compression spring and the tension spring, the upper disc can rebound after the downward pressure of the airflow, and the vibration effect can be achieved to remove dust from the filter bag. However, in actual use, high-pressure airflow is required to achieve indirect air outlet to achieve the vibration dust removal effect, which will increase the loss of high-pressure airflow and cannot effectively and continuously blow air to clean the dust from the filter bag.
