Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal filter cloths, in particular to a PTFE dust removal filter cloth structure for flue gas purification. Background Art
[0002] Dust filter cloth is a new type of industrial dust removal material. It is made of PTFE material through a special process. It has many functions such as soft texture, strong adsorption capacity, high dirt removal rate and no fiber loss. It is usually used for flue gas purification, so that dust particles in the flue gas can be removed and the flue gas can meet the emission standards.
[0003] However, when the existing PTFE dust filter cloth structure for flue gas purification is used, the dust filter cloth is usually directly fixed in the dust removal structure. As the filter cloth filters the flue gas for a long time, a thick layer of dust and dirt is easily accumulated on the surface of the filter cloth. In addition, since the filter cloth is difficult to remove, the process of cleaning the dust and dirt on the surface of the filter cloth is troublesome and time-consuming. In addition, when the existing filter cloth is removed and cleaned, the dust particles on the surface of the filter cloth are usually cleaned by directly patting. After being patted, the dust particles will float back into the air, which is very likely to cause secondary pollution, resulting in the dust filter cloth being not environmentally friendly when being cleaned.

[0023] like Figures 1 to 4 As shown, the PTFE dust filter cloth structure for flue gas purification in this embodiment includes a dust filter cloth 7, a first vertical cylinder 1 is provided on one side of the dust filter cloth 7, a rotating column 13 is provided inside the first vertical cylinder 1, a rotating spring 12 is provided on the top movable sleeve of the rotating column 13, a scraper 6 is fixedly connected to one side wall of the first vertical cylinder 1, an ash box 4 is provided on one side of the scraper 6, an ash inlet 5 is provided on one side wall of the ash box 4, an ash outlet 17 is provided at the bottom end of the ash box 4, a dirt collecting hopper 9 is fixedly connected to the bottom of the first vertical cylinder 1, a second vertical cylinder 10 is provided on the other side of the dust filter cloth 7, a rotating motor 11 is fixedly installed on the top of the second vertical cylinder 10, and a bottom cover 15 is movably threadedly connected to the bottom of the first vertical cylinder 1 and the second vertical cylinder 10.
[0024] Specifically, the dust filter cloth 7 is made of PTFE, i.e., polytetrafluoroethylene, which is a synthetic polymer material with the characteristics of heat resistance and corrosion resistance, so that the dust filter cloth 7 has a good dust removal effect. The side walls of the first vertical cylinder 1 and the second vertical cylinder 10 are both provided with openings, so that the dust filter cloth 7 can smoothly pass through the first vertical cylinder 1 and the second vertical cylinder 10. At the same time, the first vertical cylinder 1 and the second vertical cylinder 10 are both provided with cavities inside, which can temporarily store the rolled-up dust filter cloth 7, thereby facilitating the subsequent winding of the dust filter cloth 7. The rotary spring 12 is also movably connected to the top of the inner side of the first vertical cylinder 1, so that after the rotating shaft 14 drives the rotary spring 12 to rotate, the rotary spring 12 can produce elastic deformation, thereby realizing the subsequent winding of the dust filter cloth 7 by the rotating column 13. There are two scrapers 6, and the two scrapers 6 are respectively located on both sides of the opening of the first vertical cylinder 1, so that the dust filter cloth 7 can be wound around the dust filter cloth 7. When the filter cloth 7 is rolled up into the first vertical cylinder 1, the dust scale and dust particles accumulated on the surface can be cleaned up in time first. The dust collecting box 4 plays the role of temporarily collecting dust scale and dust, so that the scraped dust is not easy to float back into the air, thereby reducing the secondary pollution generated by the dust filter cloth 7 during cleaning. The ash inlet 5 can suck the dust particles scraped by the scraper 6 into the ash collecting box 4 after the ash collecting box 4 is vacuumed, thereby reducing the probability of dust particles re-entering the air. The ash outlet 17 allows the dust scale collected in the ash collecting box 4 to be cleared out from the ash collecting box 4 in time. The top of the structural bucket is not closed, so that the block dust scale scraped by the scraper 6 can fall smoothly into the scale receiving bucket 9 to realize the collection of dust scale. The second vertical cylinder 10 can cooperate with the first vertical cylinder 1, so that the dust filter cloth 7 can perform a reciprocating rolling action, thereby realizing the timely cleaning of the dust scale and dust on the dust filter cloth 7.
[0025] Furthermore, a micro vacuum pump 2 is fixedly installed at the top of the first vertical cylinder 1, and a connecting pipe 3 is sleeved on the output end of the micro vacuum pump 2. The connecting pipe 3 passes through the top of the ash collecting box 4. The micro vacuum pump 2 can evacuate the interior of the ash collecting box 4 through the connecting pipe 3, so that a suction airflow is generated at the ash inlet 5 of the ash collecting box 4, and the dust scraped off by the scraper 6 and small pieces of ash are collected, thereby reducing secondary pollution generated during cleaning.
[0026] Furthermore, one end of the dust filter cloth 7 is movably connected to a rotating column 13 , and the rotating column 13 is rotatably connected to the first vertical cylinder 1 through a rotary spring 12 . The rotating column 13 can rotate in the first vertical cylinder 1 under the action of the rotary spring 12 , thereby realizing the winding of the dust filter cloth 7 .
[0027] Furthermore, the dust filter cloth 7 is movably connected to the first vertical cylinder 1 through the rotating column 13, and the scraper 6 is movably connected to the dust filter cloth 7 through the first vertical cylinder 1. The scraper 6 can scrape the surface of the dust filter cloth 7, thereby cleaning the dirt and dust on the surface of the dust filter cloth 7.
[0028] Furthermore, the dust collecting box 4 is connected with the first vertical cylinder 1 by snapping, and the dirt collecting bucket 9 is located directly below the scraper 6, so that the dirt collecting bucket 9 can smoothly collect the block dust scraped off the scraper 6, thereby reducing the secondary pollution generated by the dust filter cloth 7 during cleaning.
[0029] Furthermore, the other end of the dust filter cloth 7 is movably connected to a rotating shaft 14, and the rotating shaft 14 is engaged with the output end of the rotary motor 11. The dust filter cloth 7 is movably connected with the second vertical cylinder 10 through the rotating shaft 14, and the rotary motor 11 can rotate forward and reverse, so that the dust filter cloth 7 can pass through the rotating shaft 14 and pass through the second vertical cylinder 10, thereby realizing reciprocating cleaning of the dust filter cloth 7.
[0030] Furthermore, the bottom of the ash outlet 17 is magnetically adsorbed and connected to a card plate 16, and a pinch rod 8 runs through the middle of the card plate 16. The card plate 16 can temporarily close the ash outlet 17 and can be opened when needed. At the same time, the top of the pinch rod 8 can be pushed to clear the ash and dirt in the ash collecting box 4 from the ash outlet 17 in time, thereby facilitating the cleaning of the ash and dirt in the ash collecting box 4.
[0031] The method of using this embodiment is as follows: when using the PTFE dust filter cloth 7 structure for flue gas purification, it is necessary to first install the structure in the dust collector, and make the flow direction of the flue gas perpendicular to the front of the dust filter cloth 7. After using the dust filter cloth 7 for a long time, the rotary motor 11 can be started, and the controller controls the motor to rotate forward, driving the rotating shaft 14 to unfold the dust filter cloth 7 in the second vertical cylinder 10, so that the dust filter cloth 7 passes through the second vertical cylinder 10. At the same time, the return spring 12, which is initially deformed, will pull the end of the dust filter cloth 7 located in the first vertical cylinder 1, so that The dust filter cloth 7 is rolled into the first vertical cylinder 1, and while being rolled into the first vertical cylinder 1, the micro vacuum pump 2 is started, so that the micro vacuum pump 2 evacuates the interior of the dust collecting box 4 through the connecting pipe 3, and at the same time, the scraper 6 scrapes the front side of the dust filter cloth 7 to scrape off the dust scale and dust particles on the surface of the dust filter cloth 7, and then the scraped dust and small pieces of dust scale will be sucked into the dust collecting box 4 through the ash inlet 5, and the larger pieces of dust scale will fall into the dirt collecting hopper 9 and be collected, so that the dust and dust scale can be temporarily collected to reduce the secondary pollution generated by the dust filter cloth 7 during cleaning.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
