Description

Flue gas dust cleaning mechanism for cast tube production Technical Field The invention relates to the technical field related to cast tube production, in particular to a flue gas and dust cleaning mechanism for cast tube production. Background Cast iron pipes, pipes cast from cast iron, often have a phenomenon of dust diffusion when cast parts are processed, and most of such dust is powder composed of metal substances, so that we need to filter the dust to remove the dust. The prior flue gas dust cleaning device scrapes the filter screen through the scraping mechanism when in use, the scraping mechanism is used for collecting the scraped dust, but in the actual use process, when the amount of the flour dust on the scraping seat is too large, the scraping effect on the filter screen is weakened, and when the dust inside the collecting box is not cleaned timely, the dust can be sucked by the air suction inlet and is involved into the device, in order to solve the problems, the dust filtering device for casting tube processing disclosed in the prior art (the Chinese patent with the application number of CN202322069750.1 and the application number of 2023-08-02) can be referred to, the dust filtering device is used for the casting tube processing disclosed by the prior art (the Chinese patent with the application number of 2023-08-02), the scraping mechanism is used for controlling the scraping plate to scrape the filter screen through the moving assembly, after the scraping is finished, the scraping effect on the scraping plate through the clamping assembly is improved, the dust on the scraping plate is cleaned, the scraping effect on the filter screen is enhanced, the scraping effect on the filter screen can be further referred to the prior art (the Chinese patent with the application number of CN202322102163.8 and the application number of 2023-08-05), the dust is convenient to move through the auxiliary motor is set up through the motor, the dust suction plate is convenient to move, the dust is convenient to move on the limit plate is set up through the limit plate through the setting up the motor, the limit plate is convenient to move, and the limit plate is convenient to move through the setting up the limit plate and the limit plate is convenient to move in use, chinese patent application No. 2023-09-13), the energy-saving bag-type dust remover for cast iron pipe processing is disclosed, when the dust remover is required to be cleaned, the air injection cylinder is inserted into the dust removing bag by controlling the electric telescopic rod, then the blower is controlled, the air injection cylinder can blow air to the dust removing bag, so that dust attached to the surface is filtered and removed, the dust removing bag is cleaned one by the displacement component, after the dust is blown, the dust can be guided into the water tank by the dust discharging component to be collected, the dust raising phenomenon is avoided, and meanwhile, the device can not generate more noise in use, so that the environmental protection of the device is better. Although the device can process dust when using, still there is certain shortcoming when using, because cast tube when producing, molten iron pouring time, high temperature molten iron and air, molding sand, coating contact, can produce iron oxide smoke and dust, form superfine metal oxide dust, rise along with the hot air flow and get into the flue gas, and too much metal oxide can cause irreversible damage to dust removal sack later stage to the impurity that the surface adhesion of dust removal sack is difficult for clean processing. So we propose a flue gas dust cleaning mechanism for cast tube production in order to solve the problems set forth above. Disclosure of Invention The invention aims to provide a flue gas and dust cleaning mechanism for cast tube production, which is used for solving the problems that when cast tubes in the market are produced, high-temperature molten iron contacts with air, molding sand and paint during molten iron pouring, iron oxide smoke dust is generated, ultrafine metal oxide dust is formed, the flue gas is risen along with hot air flow, the excessive metal oxide can cause irreversible damage to a dust removing cloth bag in the later stage, and impurities adhered to the surface of the dust removing cloth bag are not easy to clean. The flue gas and dust cleaning mechanism for the cast tube production comprises a dust hood and a purification treatment box, wherein the dust hood is communicated with the purification treatment box through a conveying pipeline, an induced air power part is arranged on the outer side of the purification treatment box, a pretreatment box is communicated with the left side of the purification treatment box, an exhaust port is formed in the top of the purification treatment box, a magnetic field part is arranged in the pretreatment box in a movable mode and used for separating metal particles in dust,
