Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an environmentally friendly industrial dust removal device. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] Currently, baghouse dust collectors are widely used in industries such as boilers, cement, chemicals, petroleum, heating, power generation, smelting, ceramics, casting, textiles, wood, pharmaceuticals, papermaking, mining, refrigeration, shipbuilding, board, gypsum board, feed, and air conditioning for ventilation, smoke extraction, and dust removal. However, the traditional baghouse dust collectors commonly used at present are not easy to clean after the filter bags are used, resulting in low subsequent filtration efficiency.

[0027] Please see Figure 1-3 As shown in this embodiment: an environmentally friendly industrial dust removal device includes a support frame 4 and a dust collection box 1 installed on the support frame 4. The dust collection box 1 contains a filter bag structure 2 and a dust removal structure 3. An air outlet 1.2 is located at the top of the dust collection box 1, communicating with the top of the filter bag structure 2. An air inlet 1.1 is connected to the bottom of the dust collection box 1. A dust hopper 1.3 is located below the filter bag structure 2, and the air inlet 1.1 is connected to the bottom of the filter bag structure 2 through the dust hopper 1.3. The dust removal structure 3 includes a support platform 3.1 and a vibrating... The filter bag structure 2 consists of multiple filter bags 2.1. The vibrating plate 3.2, elastic pad 3.3, and vibration motor 3.4 are fixed to the inner wall of the dust collector 1. The vibrating plate 3.2 is fixed to the support platform 3.1 by the elastic pad 3.3. The vibrating motor 3.4 drives the vibrating plate 3.2 to vibrate. The filter bag structure 2 consists of multiple filter bags 2.1. The vibrating plate 3.2 is provided with fixing holes 3.2.1 for fixing the filter bags 2.1. The upper end of the filter bag 2.1 is fixed in the fixing hole 3.2.1. The vibrating plate 3.2 drives the filter bag 2.1 to vibrate.

[0028] The vibrating motor 3.4 drives the vibrating plate 3.2 to vibrate, which in turn causes the filter bag 2.1 to shake, causing the dust attached to the filter bag 2.1 to fall into the ash hopper 1.3, thus achieving self-cleaning of the filter bag 2.1. The dust removal is convenient, time-saving and labor-saving.

[0029] In some embodiments, such as Figures 4-5 As shown, the dust removal structure 3 includes an air storage bag 3.5 and a blowpipe assembly 3.6. The air storage bag 3.5 is connected to the blowpipe assembly 3.6. The blowpipe assembly 3.6 is provided with a blowpipe hole 3.7 corresponding to the opening end of the filter bag 2.1. It should be noted that the compressed air in the compressed air bag is blown out from the blowpipe assembly 3.6 through the blowpipe hole 3.7, thereby blowing dust into the inside of the filter bag 2.1, thus achieving the purpose of self-cleaning of the filter bag 2.1.

[0030] In some embodiments, such as Figures 6-7 As shown, the filter bag structure 2 includes a fixed housing 2.2, which is located on top of the filter bag 2.1. The filter bag 2.1 is fixed in the fixing hole 3.2.1 through the fixed housing 2.2. It should be noted that fixing the filter bag 2.1 in the fixing hole 3.2.1 through the fixed housing 2.2 makes the connection between the filter bag 2.1 and the fixing hole 3.2.1 tighter and more secure, resulting in better equipment stability.

[0031] In some embodiments, such as Figure 7 As shown, the fixed housing 2.2 includes a fixing part 2.2.1 and a connecting part 2.2.2. The fixing part 2.2.1 is fixed in the fixing hole 3.2.1, and the connecting part 2.2.2 is located above the fixing part 2.2.1. The diameter of the connecting part 2.2.2 gradually decreases from bottom to top. It should be noted that the tapered design of the connecting part 2.2.2 with a gradually decreasing diameter can disperse the instantaneous high pressure generated during pulse jet cleaning, reduce stress concentration at the connection between the filter bag and the housing, thereby reducing the risk of filter bag breakage. At the same time, it can more concentratedly introduce the compressed air ejected from the pulse valve into the interior of the filter bag, forming a high-speed airflow wave, which can reach several times the jet air volume, enhancing the dust removal effect.

[0032] In some embodiments, such as Figure 7 As shown, the fixed housing 2.2 includes a blowing section 2.2.3, which is located above the connecting section 2.2.2. The blowing section 2.2.3 has a hollow cylindrical center. It should be noted that the hollow cylindrical structure of the blowing section 2.2.3 can concentrate the compressed air released by the pulse valve to the central axis of the filter bag, forming a directional airflow channel. The gradually decreasing diameter design of the connecting section 2.2.2, together with the cylindrical blowing section 2.2.3, can create a Venturi effect, further accelerating the airflow and enhancing the impact force on the filter bag.

[0033] In some embodiments, such as Figure 5 As shown, the dust removal structure 3 includes a pulse solenoid valve 3.8, and the blow pipe assembly 3.6 includes multiple horizontal pipes 3.6.1. Blow holes 3.7 are provided on the horizontal pipes 3.6.1. The horizontal pipes 3.6.1 are connected to the air storage bag 3.5 through the pulse solenoid valve 3.8, and the horizontal pipes 3.6.1 and the pulse solenoid valves 3.8 correspond one-to-one. It should be noted that the airflow blowing on / off of the horizontal pipes 3.6.1 can be controlled by the pulse solenoid valves 3.8 to effectively utilize resources.

[0034] Working principle: During operation, dusty air enters the dust collector 1 through the air inlet 1.1, passes through the filter bag 2.1 to remove dust, and is then discharged from the air outlet 1.2 as clean air. During the self-cleaning process of the filter bag 2.1, the vibration motor 3.4 is first turned on to pre-treat the filter bag 2.1 by vibrating through the vibration plate 3.2, causing the filter bag 2.1 to shake and the dust adhering to it to fall into the dust hopper 1.3. The vibration motor 3.4 is then turned off, and the pulse solenoid valve 3.8 is opened. Compressed air from the compressed air tank is ejected through the blowpipe assembly 3.6 from the blowhole 3.7, thus blowing dust from the inside of the filter bag 2.1 and completing the dust removal process.

[0035] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
