Existing industrial furnaces produce a large amount of flue gas when they are working, and the flue gas contains incineration dust, harmful gases, etc., so waste gas treatment mechanisms are needed;

[0003] For example, the patent CN218011844U discloses an environmentally friendly industrial furnace for industrial manufacturing. The prior art provides a function of electrically cleaning the sediment on the surface of the filter screen by setting a guide rod, a threaded rod, a scraper, a motor, and a disassembly plate to prevent the filter screen from being blocked.

[0004] However, the inventors have discovered that the prior art has the following problems in use: when the existing scraper is used to clean solid impurities on the surface of the filter, the scraper cannot completely clean all the solid impurities on the surface of the filter in one movement; if the scraper moves back and forth to clean the surface of the filter, the scraper will easily push the solid impurities to the side away from the disassembly plate, and the solid impurities on the surface of the filter cannot be effectively cleaned; if the solid impurities on the surface of the filter need to be completely cleaned, the staff will need to remove the disassembly plate and the entire filter from the filter box before the surface of the filter can be cleaned. This method increases the staff's workload and reduces the staff's cleaning efficiency inside the filter box. In response to the above problems, the inventors have designed an environmentally friendly industrial furnace that is convenient for exhaust gas treatment. Utility Model Content

DETAILED DESCRIPTION

[0022] See also Figure 1-4 , the utility model provides the following technical solutions:

[0023] Specifically, it refers to an environmentally friendly industrial furnace that is convenient for exhaust gas treatment, including an industrial furnace 1 and a filter box 2, a flue 3 is installed between the industrial furnace 1 and the filter box 2, and is used to transport the waste in the industrial furnace 1 to the filter box 2, and the filter box 2 is fixedly connected to an exhaust pipe 4 on the side away from the flue 3, and the exhaust pipe 4 is connected to the filter box 2, and a spray dust reduction mechanism 5 is provided in the filter box 2, and the spray dust reduction mechanism 5 is a known technology in the existing patent: CN218011844U, and no further description is made here, and a filter screen 6 is installed in the filter box 2, and the filter screen 6 is located at the lower side of the spray dust reduction mechanism 5;

[0024] When in use, the exhaust gas in the industrial furnace 1 enters the filter box 2, and the spray dust reduction mechanism 5 operates to purify the dust and harmful gases in the exhaust gas, and the purified gas is finally discharged through the exhaust pipe 4. At the same time, the filter screen 6 can filter the spray water and block the dust, so that the spray water can be reused again;

[0025] Specifically, two pulleys 9 arranged horizontally and parallelly are rotatably connected to the inner wall of the filter box 2, a transmission belt 10 is transmission-connected between the two pulleys 9, a connection block 11 is fixedly connected to the outer surface of the transmission belt 10, a scraper 12 is fixedly connected to the other side of the connection block 11, and the other side of the scraper 12 contacts and slides with the upper surface of the filter screen 6, a servo motor 13 is fixedly connected to the outer surface of the filter box 2, and the output shaft of the servo motor 13 rotates and penetrates into the filter box 2 and is fixedly connected to a pulley 9;

[0026] Specifically, an L-shaped bracket 7 is fixedly connected to the side wall of the filter box 2, and the L-shaped bracket 7 is arranged on the side direction of the scraper 12 to scrape off the dust. At the same time, the opposite sides of the L-shaped bracket 7 are fixed to the inner walls of the filter box 2 on both sides. One side of the filter screen 6 is fixed to the vertical plate of the L-shaped bracket 7, and the surface is flush with the upper surface of the vertical plate of the L-shaped bracket 7. A drawer 8 is provided on the outside of the filter box 2, and one side of the drawer 8 slides through the L-shaped bracket 7 and is slidably connected to the upper surface of the horizontal plate of the L-shaped bracket 7.

[0027] When in use, the servo motor 13 is running, and the output shaft of the servo motor 13 synchronously drives the pulley 9 to rotate counterclockwise, and the transmission belt 10 is synchronously transported, so that the transmission belt 10 can drive the scraper 12 to slide on the filter screen 6, so the scraper 12 can scrape the fixed impurities accumulated on the surface of the filter screen 6 to one side of the drawer 8, and these scraped solid impurities can eventually fall into the drawer 8, so the staff only needs to pull out the drawer 8 to clean these solid impurities, which is convenient for collecting and cleaning the solid impurities in the filter box 2, reducing the work intensity of the staff, and further improving the cleaning efficiency of the solid impurities in the filter box 2. At the same time, the two pulleys 9 are used to drive the scraper 12 to move, so that the surface of the filter screen 6 can be repeatedly cleaned, and the problem that the solid impurities on the surface of the filter screen 6 are not cleaned cleanly will not occur, and the scraper 12 cannot clean the surface of the filter screen 6, which further ensures the cleaning effect of the filter screen 6;

[0028] In this embodiment, a sealing gasket is additionally provided on the outer surface of the drawer 8, which increases the sealing between the drawer 8 and the inner wall of the filter box 2, and prevents the gas in the filter box 2 from penetrating through the gap between the drawer 8 and the filter box 2, thereby affecting the filtering effect of the filter box 2 on the exhaust gas.

[0029] Specifically, a rotating shaft 14 is rotatably connected between the inner walls of the two opposite sides of the filter box 2, and a baffle 15 is fixedly sleeved on the outer surface of the rotating shaft 14. The bottom of the baffle 15 extends into the L-shaped bracket 7 and blocks the top of the L-shaped bracket 7. A torsion spring 16 is provided between the rotating shaft 14 and the inner wall of the filter box 2. One end of the torsion spring 16 is fixed on the rotating shaft 14, and the other end is fixed on the inner wall of the filter box 2. When the torsion spring 16 is not affected by pressure, the torsion spring 16 will add tension to the rotating shaft 14, so that the initial state of the baffle 15 is inclined and blocks the top of the L-shaped bracket 7. This method is used to avoid the spray water from falling into the drawer 8 when the spray dust reduction mechanism 5 is in operation, thereby improving the collection effect of solid impurities and ensuring the secondary utilization of the spray water.

[0030] Specifically, a connecting plate 17 is provided on the side of the baffle 15 facing the filter screen 6, and a contact block 18 is fixedly connected to the side of the connecting plate 17 facing away from the baffle 15. The contact block 18 is semicircular in shape, and a rotating push plate 19 is rotatably connected between the connecting plate 17 and the baffle 15. When the baffle 15 is inclined, the rotating push plate 19 is horizontal. When the scraper 12 is displaced and close to one side of the baffle 15, the scraper 12 contacts the contact block 18 and forms a thrust on the contact block 18, so that the connecting plate 17 is displaced to the side close to the baffle 15, and at the same time, the rotating push plate 19 pushes the baffle 15, so that the baffle 15 rotates counterclockwise with the rotating shaft 14 as the rotation point, and at the same time, the torsion spring 16 is deformed, so that the baffle 15 no longer blocks the drawer 8, so that the solid impurities on the filter screen 6 can be scraped into the drawer 8, and when the scraper 12 is no longer in contact with the contact block 18, the baffle 15 is driven by the torsion spring 16 to block the top of the L-shaped bracket 7 again;

[0031] Specifically, a limiting groove 20 is opened on the inner wall of the filter box 2 on one side close to the connecting plate 17, and the limiting groove 20 is T-shaped. A limiting slider 21 is fixedly connected to the side of the connecting plate 17 close to the limiting groove 20. The limiting slider 21 slides in the limiting groove 20 and matches with the limiting groove 20. In this way, the limiting slider 21 forms a limiting effect on the connecting plate 17 to prevent the connecting plate 17 from tilting.

[0032] The working principle of the environmentally friendly industrial furnace for facilitating exhaust gas treatment provided by the utility model is as follows: the servo motor 13 is running, and the output shaft of the servo motor 13 synchronously drives the pulley 9 to rotate counterclockwise, and the transmission belt 10 is synchronously conveyed, so that the transmission belt 10 can drive the scraper 12 to slide on the filter screen 6, so that the scraper 12 can scrape the fixed impurities accumulated on the surface of the filter screen 6 to one side of the drawer 8;

[0033] When the scraper 12 is displaced and approaches the side of the baffle 15, the scraper 12 contacts the contact block 18 and forms a thrust on the contact block 18, so that the connecting plate 17 is displaced to the side close to the baffle 15, and the push plate 19 is rotated to push the baffle 15, so that the baffle 15 rotates counterclockwise with the rotating shaft 14 as the rotation point, and the torsion spring 16 is deformed at the same time, so that the baffle 15 no longer blocks the drawer 8, so that the solid impurities on the filter screen 6 can be scraped into the drawer 8, and when the scraper 12 is no longer in contact with the contact block 18, the baffle 15 is driven by the torsion spring 16 to block the top of the L-shaped bracket 7 again.
