Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to waste gas treatment equipment. Background Art

[0002] Waste gas will be generated during the production of calcium carbonate. These waste gases may contain a large amount of toxic and harmful substances, such as sulfur dioxide and nitrous oxide. If they are discharged into the environment without treatment, they will cause serious pollution to the surrounding environment. Waste gas treatment equipment can effectively treat the waste gas, convert it into harmless substances, and prevent waste gas emissions from affecting the environment.

[0003] When treating the waste gas generated during the calcium carbonate production process, filtering out particles and dust in the waste gas is the first step. In current technology, there are two common methods for cleaning and maintaining the filter plate, but each has its limitations;

[0004] First, a common method is to scrape the filter plate through the transmission structure to remove the accumulated dust. Although this method can effectively remove the dust on the surface of the filter plate, its disadvantage is that the dust may accumulate under the filter plate. When the exhaust gas passes through the filter plate again, the accumulated dust will be blown up by the exhaust gas and re-attached to the filter plate, forming a vicious cycle. This requires frequent scraping operations and cannot fundamentally solve the problem of secondary dust adhesion.

[0005] Another method is to use a detachable filter plate and replace or clean it regularly by the user. However, the disadvantage of this method is that it is difficult for the user to accurately judge the degree of dust accumulation on the filter plate. If the cleaning is not timely, the filtering effect of the filter plate will be seriously affected, thereby affecting the efficiency and effect of the exhaust gas treatment. In addition, frequent replacement or cleaning of the filter plate also increases time and labor costs. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0029] See also Figure 1-Figure 4As shown, an exhaust gas treatment device includes an exhaust gas treatment device 1, which is fixedly installed with an air intake head 2, two rotating rods 12 are arranged in the air intake head 2, a servo motor 13 is arranged in the air intake head 2, the driving end of the servo motor 13 is connected to one end of one of the rotating rods 12, an impeller 10 is fixedly installed on the outer wall of the rotating rod 12, a transmission belt 16 is cross-transmission connected between the two rotating rods 12, a filter plate 8 is arranged in the air intake head 2, a plurality of springs 23 are connected to the top and bottom of the filter plate 8, and one end of the spring 23 away from the filter plate 8 is fixedly connected to the air intake head 2, a fixing rod 9 is fixedly installed on the outer wall of the filter plate 8, a protrusion 11 is fixedly installed on the outer wall of one of the rotating rods 12, the fixing rod 9 is located above one of the rotating rods 12 and close to the rotating rod 12, one end of one of the rotating rods 12 is rotatably connected to the inner wall of the air intake head 2, a pulley 15 is fixedly installed on the outer wall of the rotating rod 12, and the transmission belt 16 is connected between the two pulleys 15.

[0030] The servo motor 13 drives one of the rotating rods 12 to rotate, which drives the impeller 10 on the rotating rod 12 to rotate together. The rotating rod 12 rotates together with the pulley 15. Because the transmission belt 16 is in a cross form, the upper rotating rod 12 rotates and drives the other pulley 15, the rotating rod 12 and the impeller 10 to rotate in the opposite direction through the transmission belt 16. The upper impeller 10 rotates to generate suction, so that the exhaust gas is sucked into the intake head 2;

[0031] The impeller 10 at the bottom rotates in the opposite direction, so the impeller at the bottom pushes the air to flow outward, and the impeller 10 at the top rotates to generate suction, and after the exhaust gas is sucked into the air intake head 2, the dust and particles inside the exhaust gas will be intercepted by the filter plate 8 when the exhaust gas passes through the filter plate 8, and then the gas passes through the impeller 10 and the servo motor 13 into the exhaust gas treatment device 1, so that the harmful substances in the gas can be treated by the exhaust gas treatment device 1;

[0032] When the rotating rod 12 at the top rotates, the protrusion 11 is driven to rotate. When the protrusion 11 rotates to the position of the fixed rod 9, it hits the fixed rod 9. The fixed rod 9 and the filter plate 8 shake and vibrate together. At the same time, the filter plate 8 squeezes the spring 23. The spring 23 allows the filter plate 8 to shake up and down. The shaking of the filter plate 8 causes the impurities and dust adhering to the outer wall of the filter plate 8 to be shaken off.

[0033] When the shaken impurities and dust fall downward, the blowing force generated by the lower impeller 10 will blow the impurities and dust toward the outside of the air intake head 2, so that the dust is automatically blown out of the air intake head 2, thereby achieving self-cleaning of the impurities and dust.

[0034] See also Figure 2A support plate 18 is fixedly installed on the inner wall of the air intake head 2. The support plate 18 has a through groove 22. The filter plate 8 is located inside the through groove 22. One impeller 10 is located above the support plate 18, and the other impeller 10 is located below the support plate 18.

[0035] The support plate 18 separates the two impellers 10 to prevent the two impellers 10 from affecting each other. Impurities and dust on the filter plate 8 fall downward through the through groove 22, making it convenient for the impeller 10 below to blow dust out of the air inlet head 2.

[0036] See also Figure 3 A partition plate 24 is fixedly installed on the inner top wall of the air intake head 2, and the outer wall of the partition plate 24 is tightly attached to the outer wall of the filter plate 8. The partition plate 24 is located on one side of the multiple springs 23 on the top of the filter plate 8. A hydraulic rod 27 is fixedly installed on the inner top wall of the partition plate 24, and a scraper rod 28 is fixedly installed on the telescopic end of the hydraulic rod 27. The scraper rod 28 is against the outer wall of the filter plate 8, and the scraper rod 28 is adapted to the through groove 22.

[0037] The partition 24 blocks the gap between the top of the filter plate 8 and the inner top wall of the air intake head 2 to prevent the exhaust gas from passing through the position of the upper spring 23. The suction force generated by the upper impeller 10 will prevent dust and impurities from falling downward. Therefore, the scraper rod 28 is driven downward by the hydraulic rod 27, and the scraper rod 28 pushes the dust and impurities adhered to the outer wall of the filter plate 8 downward. When the scraper rod 28 moves into the through groove 22, the scraper rod 28 just blocks the through groove 22. At this time, the dust has been pushed to the bottom of the support plate 18, making it convenient for the impeller 10 below to blow out the dust.

[0038] See also Figure 1-Figure 2 An arc block 6 is fixedly installed on the top of the support plate 18, an inclined plate 7 is fixedly installed on the outer wall of the arc block 6, the bottom of the inclined plate 7 corresponds to the through groove 22, and an air collecting hood 3 is fixedly installed on the outer wall of the air intake head 2, and the air collecting hood 3 is connected to the interior of the air intake head 2.

[0039] The air collecting hood 3 enlarges the air inlet of the air intake head 2, making it easier for the exhaust gas to be sucked into the air intake head 2. The arc block 6 allows the exhaust gas to pass through the surface of the arc block 6 and blow directly onto the filter plate 8. The inclined plate 7 blocks the arc block 6 to prevent dust from floating onto the arc block 6.

[0040] See also Figure 2 A triangular block 5 is fixedly installed on the bottom of the support plate 18 , and an arc-shaped guide plate 17 is fixedly installed on the outer wall of the air intake head 2 , and the arc-shaped guide plate 17 corresponds to the triangular block 5 .

[0041] The triangular block 5 and the arc-shaped guide plate 17 limit the impurities and dust, so that the impurities and dust can be blown out of the air inlet head 2 along the space between the triangular block 5 and the arc-shaped guide plate 17 .

[0042] See also Figure 2A plurality of sleeves 19 are fixedly installed on the inner bottom wall of the air intake head 2, a plurality of sleeve rods 20 are fixedly installed on the bottom of the filter plate 8, a partial area of ​​the sleeve rod 20 is located inside the sleeve 19, and a spring 23 under the filter plate 8 is located inside the sleeve 19 and the sleeve rod 20.

[0043] When the filter plate 8 swings up and down or left and right, the sleeve rod 20 will slide along the sleeve 19, so that the filter plate 8 can swing vertically up and down, thereby preventing the filter plate 8 from deflecting.

[0044] See also Figure 2-Figure 4 The support plate 18 is provided with a slot 25 , the transmission belt 16 is located inside the slot 25 , a bracket 14 is fixedly mounted on the inner wall of the air intake head 2 , and the servo motor 13 is fixedly mounted inside the bracket 14 .

[0045] The slot 25 provides a space for the transmission belt 16 to rotate, and a sealing gasket is arranged in the slot 25. The sealing gasket is in close contact with the outer wall of the transmission belt 16 to avoid the suction and blowing forces generated by the two impellers 10 from affecting each other. The bracket 14 is used to fix the servo motor 13 in the air intake head 2 to ensure the stability of the air intake head 2.

[0046] See also Figure 2 A baffle 21 is provided on one side of the triangular block 5, and a plurality of torsion spring hinges 26 are hinged between the baffle 21 and the triangular block 5. The outer wall of the arc guide plate 17 is connected to the storage box 4, and the storage box 4 is located on one side of the baffle 21. The baffle 21 is located on one side of the arc guide plate 17 and the triangular block 5.

[0047] The torsion spring hinge 26 allows the baffle 21 to open and close only toward the outside of the air inlet head 2. When the blowing force generated by the impeller 10 blows the baffle 21 outward, dust will be blown directly into the storage box 4. When the impeller 10 stops operating, the torsion spring hinge 26 will close the baffle 21 back to its original position.

[0048] Working principle:

[0049] A single chip microcomputer is connected to the bottom of the air intake head 2, and the single chip microcomputer can control the servo motor 13 and the hydraulic rod 27 to start continuously, and can also control the servo motor 13 and the hydraulic rod 27 to pause at the same time. The power cord used to connect the servo motor 13 and the arc-shaped guide plate 17 to the power supply can extend from one side of the air intake head 2. A hole can be opened on one side of the air intake head 2 for inserting only the power cord, and a sealing material can be used to block the gap between the hole and the power cord to avoid affecting the transmission of gas in the air intake head 2;

[0050] The servo motor 13 drives one of the rotating rods 12 to rotate, which drives the impeller 10 on the rotating rod 12 to rotate together. The rotating rod 12 rotates together with the pulley 15. Because the transmission belt 16 is in a cross form, the upper rotating rod 12 rotates and drives the other pulley 15, the rotating rod 12 and the impeller 10 to rotate in the opposite direction through the transmission belt 16. The upper impeller 10 rotates to generate suction, so that the exhaust gas is sucked into the intake head 2;

[0051] The impeller 10 at the bottom rotates in the opposite direction, so the impeller at the bottom pushes the air to flow outward, and the impeller 10 at the top rotates to generate suction, and after the exhaust gas is sucked into the air intake head 2, the dust and particles inside the exhaust gas will be intercepted by the filter plate 8 when the exhaust gas passes through the filter plate 8, and then the gas passes through the impeller 10 and the servo motor 13 into the exhaust gas treatment device 1, so that the harmful substances in the gas can be treated by the exhaust gas treatment device 1;

[0052] When the rotating rod 12 at the top rotates, the protrusion 11 is driven to rotate. When the protrusion 11 rotates to the position of the fixed rod 9, it hits the fixed rod 9. The fixed rod 9 and the filter plate 8 shake and vibrate together. At the same time, the filter plate 8 squeezes the spring 23. The spring 23 allows the filter plate 8 to shake up and down. The shaking of the filter plate 8 causes the impurities and dust adhering to the outer wall of the filter plate 8 to be shaken off.

[0053] When the shaken impurities and dust fall downward, the blowing force generated by the lower impeller 10 will blow the impurities and dust toward the outside of the air intake head 2, so that the dust is automatically blown out of the air intake head 2, thereby achieving self-cleaning of the impurities and dust.

[0054] The torsion spring hinge 26 allows the baffle 21 to open and close only toward the outside of the air inlet head 2. When the blowing force generated by the impeller 10 blows the baffle 21 outward, dust will be blown directly into the storage box 4. When the impeller 10 stops operating, the torsion spring hinge 26 will close the baffle 21 back to its original position.
