Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically a waste gas collection and treatment device for the foundry industry. Background Technology

[0002] Waste gas from the foundry industry refers to gaseous pollutants generated and emitted into the surrounding environment during the foundry production process due to various technological operations. These mainly include dust, sulfur dioxide, nitrogen oxides, and volatile organic compounds.

[0003] When treating foundry waste gas, waste collection and treatment devices are often used. Although existing waste collection and treatment devices can treat waste gas, they generally do not have the function of scraping off the scale at the bottom of the spray box. Since limestone liquid reacts with sulfur dioxide gas to produce gypsum and other substances, gypsum will gradually accumulate and form scale at the bottom of the spray box over time, which will lead to poor spraying effect and reduce waste gas treatment efficiency. Therefore, it is necessary to improve them. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a waste gas collection and treatment device for the foundry industry, which has the advantage of automatically scraping off scale buildup on the bottom plate of the spray box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a waste gas collection and treatment device for the foundry industry, including a waste gas treatment box 1. A water pump 2 is fixedly connected to the top of the waste gas treatment box 1. A drain pipe 3 is fixedly connected to the top of the water pump 2. The bottom of the drain pipe 3 penetrates the waste gas treatment box 1 and extends into the interior of the waste gas treatment box 1, and a spray box 4 is fixedly sleeved thereon. A drive motor 5 is fixedly connected to the front of the waste gas treatment box 1. A rotating shaft 6 is fixedly sleeved at the other end of the output shaft of the drive motor 5. A rotating rod 7 is fixedly sleeved on the outer surface of the rotating shaft 6. A round shaft 8 is fixedly sleeved inside the other end of the rotating rod 7. A T-shaped block 9 is movably connected to the outer surface of the round shaft 8. The other end of the T-shaped block 9 penetrates the waste gas treatment box 1 and extends into the interior of the waste gas treatment box 1, and a scraper 10 is fixedly connected thereon. The outer surface of the scraper 10 is movably connected to the inner surface of the waste gas treatment box 1.

[0023] When the drive motor 5 is running, the rotating shaft 6 will drive the rotating rod 7 to rotate, which in turn will cause the round shaft 8 to rotate and drive the T-shaped block 9 to move to the right, thereby causing the scraper 10 to move to the right to scrape off the scale at the bottom of the spray box 4.

[0024] The waste gas treatment box 1 is fixedly connected to the left side of the liquid collection box 1, and the water pump 2 is fixedly connected to the left side of the liquid suction pipe 12. The bottom of the liquid suction pipe 12 passes through the liquid collection box 11 and extends into the interior of the liquid collection box 11.

[0025] With this design, when the water pump 2 is running, it will drive the suction pipe 12 to draw the limestone liquid inside the collection tank 11.

[0026] The top of the liquid collection tank 11 is fixedly connected to a liquid inlet 13, which is circular in appearance.

[0027] The design of the liquid inlet 13 facilitates the addition of limestone liquid into the liquid collection tank 11 through the liquid inlet 13.

[0028] The exhaust gas treatment box 1 contains a treatment liquid 14, an air inlet pipe 15 is fixedly connected to the inside of the right side of the exhaust gas treatment box 1, and an exhaust pipe 16 is fixedly connected to the top of the exhaust gas treatment box 1.

[0029] The exhaust gas enters the interior of the exhaust gas treatment box 1 through the air inlet pipe 15. After being pretreated by the treatment liquid 14, the dust settles to the bottom of the exhaust gas treatment box 1. Then the exhaust gas bubbles in the treatment liquid 14 and floats to the top of the treatment liquid 14.

[0030] Among them, a valve 17 is fixedly installed at the bottom right side of the exhaust gas treatment box 1, and a connecting pipe 18 is fixedly connected to the right side of the valve 17.

[0031] Opening valve 17 allows the liquid inside the waste gas treatment box 1 to be discharged to the outside through connecting pipe 18.

[0032] The exhaust gas treatment box 1 has a fixed connection to a lifting motor 19 located directly below the drive motor 5 on the front side. The other end of the output shaft of the lifting motor 19 is fixedly sleeved with a transmission shaft 20. A rotating rod 21 is fixedly sleeved on the outer surface of the transmission shaft 20. The back of the rotating rod 21 is movably connected to the front side of the exhaust gas treatment box 1. A cylindrical block 22 is movably connected to the inner surface of the rotating rod 21. The outer surface of the cylindrical block 22 is movably connected to the inner wall of the exhaust gas treatment box 1. A lifting plate 23 is fixedly connected to the back of the cylindrical block 22. The outer surface of the lifting plate 23 is movably connected to the inner wall of the exhaust gas treatment box 1.

[0033] When the lifting motor 19 is running, the transmission shaft 20 will drive the rotating rod 21 to rotate, which in turn will cause the rotating rod 21 to rotate and drive the cylindrical block 22 to move upward, thereby driving the lifting plate 23 to move upward and release the sealing effect on the exhaust gas treatment box 1, making it easier to clean the sediment at the bottom of the exhaust gas treatment box 1.

[0034] The lifting plate 23 is fixedly connected to the back of the sealing plate 24, and the outer surface of the sealing plate 24 is movably connected to the inner wall of the exhaust gas treatment box 1.

[0035] The design of the sealing plate 24 ensures the overall sealing performance of the exhaust gas treatment box 1.

[0036] Working principle and usage process of this utility model:

[0037] When collecting and treating foundry waste gas, the waste gas is first introduced into the interior of the waste gas treatment box 1 through the inlet pipe 15. After the waste gas is pretreated by the treatment liquid 14, the dust in the waste gas settles to the bottom of the waste gas treatment box 1, and the waste gas floats to the top of the treatment liquid 14 in a bubbling manner. At the same time, the water pump 2 is started, which will cause the suction pipe 12 to draw the limestone liquid inside the collection tank 11 and transport it to the interior of the spray box 4 through the drain pipe 3. Then, the spray box 4 sprays the waste gas to perform desulfurization treatment. The desulfurized gas is discharged from the exhaust pipe 16.

[0038] When a large amount of scale remains at the bottom of the spray box 4, the drive motor 5 is started, which will cause the rotating shaft 6 to drive the rotating rod 7 to rotate, which in turn causes the round shaft 8 to rotate and drive the T-shaped block 9 to move to the right. This causes the scraper 10 to move to the right to scrape off the scale at the bottom of the spray box 4, thus improving the efficiency of waste gas treatment.

[0039] Since dust and gypsum settle at the bottom of the exhaust gas treatment box 1, failure to clean them will cause blockage of the connecting pipe 18. At this time, starting the lifting motor 19 will cause the transmission shaft 20 to drive the rotating rod 21 to rotate, which in turn causes the rotating rod 21 to rotate and drive the cylindrical block 22 to move upward, thereby driving the lifting plate 23 to move upward and release the sealing effect on the exhaust gas treatment box 1, thus achieving the purpose of facilitating the cleaning of the sediment at the bottom of the exhaust gas treatment box 1.
