Description

Technical Field

[0001] The present invention relates to the technical field of industrial waste ash recycling, and specifically to a recycling system for waste dust in casting. Background Art

[0002] A dust collection device is a crucial environmental protection equipment, mainly used to capture and remove suspended particulate matter in the air, such as dust, coal dust, iron powder, etc. In industrial production, laboratories and other places, the generation of dust is inevitable. These fine particles not only pose a threat to human health, but also cause wear and blockage to equipment and machines, and pollute the atmospheric environment. Therefore, the role of dust collection devices in these places is particularly important.

[0003] The existing Chinese patent with the publication number CN213221329U discloses a dust collection system, which includes a collection shell, a dust guide pipe, a bag filter, an induced draft fan, and an air inlet pipe. The collection shell is arranged on the ground near the cutting machine. One end of the dust guide pipe is connected to the collection shell, and the other end of the dust guide pipe is connected to the air inlet of the bag filter. The air outlet of the bag filter is connected to the air inlet of the induced draft fan through a pipeline, and the air outlet of the induced draft fan is connected to the air inlet pipe.

[0004] There is also a dust collection device disclosed in the existing application No. 2024202585131. This dust collection device can make water molecules adsorb dust particles and settle them by spraying water, making the discharge of dust more convenient. However, it is not applicable to oil and gas molecules. Due to the influence of oil and gas molecules sticking to the bag, the inner wall of the bag becomes sticky and cannot be cleaned.

[0005] Although the above solutions are convenient for collecting dust and reducing secondary dust pollution, it is not easy to take out the collected dust for treatment after the device collects dust, resulting in inconvenient material taking. Frequent manual cleaning can lead to pneumoconiosis, ultimately affecting the use. Especially for bagged collection or replacement, it is very troublesome and costly. Summary of the Invention

[0006] In order to collect and output dust in bags, especially for the collection of molecules containing oil and gas, the present invention particularly provides a recycling system for waste dust in casting.

[0007] For this reason, the technical solution of the present invention is a recycling system for casting waste dust, which includes a regenerative dust collector, a shot blasting dust collector, a shakeout dust collector, or multiple dust collectors respectively connected to a vertical waste ash hopper through a first fan, a second fan, a third fan, or multiple fans, and the vertical waste ash hopper is then output through waste ash humidifying and stirring. It is characterized in that: the vertical waste ash hopper is respectively connected to a casting dust collector and a hot work room dust collector through a fan, and a first dust removal cloth bag and a second dust removal cloth bag are arranged inside the casting dust collector and the hot work room dust collector; among them, the casting dust collector and the hot work room dust collector are then sent to the vertical waste ash hopper through a pneumatic conveying tank, and finally output through waste ash humidifying and stirring.

[0008] The effect is that in the present invention, the regenerative dust collector, the shot blasting dust collector, the shakeout dust collector, or multiple dust collectors all remove the collection by ton bags, and are output through waste ash humidifying and stirring by the vertical waste ash hopper. At this time, most of the larger particle dust can be output through waste ash humidifying and stirring; However, for finer dust or dust smaller than PM2.5, it cannot be humidified. Then, the casting dust collector and the hot work room dust collector are respectively connected through a fan. At this time, the dust smaller than PM2.5 adheres to the oil and gas molecules brought by the casting dust collector and the hot work room dust collector. The greatest advantage is that the oil and gas molecules can adhere the fine powdered dust together. At the same time, due to the mixing of oil and gas and dust, the viscosity of the oil and gas is reduced by the mixing viscosity of the dust. The larger particles after mixing naturally fall into the first dust removal cloth bag or the second dust removal cloth bag; the smaller particles after mixing, the oil and gas, and the dust return to the vertical waste ash hopper through the pneumatic conveying tank, and finally are output through waste ash humidifying and stirring, forming a closed-loop circuit. This not only facilitates the collection of oil and gas and dust, but also facilitates the collection of mixed dust; The pneumatic conveying tank can effectively transport materials from one point to another, and is suitable for industries such as chemical industry, ceramics, and forging; during the transportation process, the pneumatic conveying tank can avoid the materials from being affected by moisture, pollution, and mixing with other sundries, ensuring the transportation quality; the pneumatic conveying tank can achieve multi-point feeding and multi-point discharging, adapting to different production process layouts; due to the closed pipeline transportation, the pneumatic conveying tank can achieve remote operation and is not affected by environmental, climatic and other conditions; the fully enclosed pipeline transportation reduces dust flying and meets environmental protection requirements.

[0009] A further improvement is that: the first dust removal cloth bag and the second dust removal cloth bag are a first water-repellent and oil-proof polyester needle felt and a second water-repellent and oil-proof polyester needle felt.

[0010] The effect is that the built-in water-repellent and oil-proof polyester needle felt is convenient for collecting the waste ash particles after the viscosity reduction of the oil and gas dust mixture. The cleaning of the dust removal cloth bag is very convenient, and the service life is extended.

[0011] A further improvement lies in that: the blower is a Roots blower, wherein the first Roots blower is connected to the casting dust collector, and the second Roots blower is connected to the fire workshop dust collector.

[0012] The effect is that: the blower is a Roots blower. The Roots blower itself cannot transport gases containing a large amount of solid media. It is mainly used to transport clean air. In the waste ash transportation, the Roots blower provides pneumatic kinetic energy to assist in transporting the required waste ash.

[0013] A further improvement lies in that: the casting dust collector and the fire workshop dust collector are respectively connected to the vertical waste ash hopper through the first pneumatic conveying tank and the second pneumatic conveying tank.

[0014] The effect is that: the separate settings of the pneumatic conveying tanks are beneficial to the transmission of dust.

[0015] A further improvement lies in that: the casting dust collector and the fire workshop dust collector are also respectively provided with a first soot blowing trolley and a second soot blowing trolley.

[0016] The effect is that: the separate settings of the first soot blowing trolley and the second soot blowing trolley are beneficial to the rapid separation of the oil-gas waste ash particles adhering to the dust removal cloth bags. The separated oil-gas waste ash particles return to the vertical waste ash hopper through the pneumatic conveying tank and are finally output through the waste ash humidifying and stirring. Beneficial effects:

[0017] In the present invention, the ton bag collection is removed from the regeneration dust collector, the shot blasting dust collector, and the shakeout dust collector, and the waste ash is output through the vertical waste ash hopper with waste ash humidifying and stirring. At this time, some larger particle dust can be output through the waste ash humidifying and stirring; at this time, the dust smaller than PM2.5 adheres to the oil-gas molecules brought by the casting dust collector and the fire workshop dust collector. The greatest advantage is that the oil-gas molecules can adhere the fine powdery dust together. At the same time, due to the mixing of the oil-gas and the dust, the viscosity of the oil-gas is reduced by the mixing viscosity of the dust, and the mixed larger particles naturally fall into the first dust removal cloth bag or the second dust removal cloth bag; the mixed smaller particles, the oil-gas, and the dust return to the vertical waste ash hopper through the pneumatic conveying tank and are finally output through the waste ash humidifying and stirring, forming a closed-loop circuit. This not only facilitates the collection of oil-gas and dust, but also facilitates the collection of mixed dust; Description of the drawings

The vertical waste ash hopper is further connected to a casting dust collector and a hot work room dust collector through blowers respectively. The casting dust collector and the hot work room dust collector are internally provided with a first dust removal cloth bag and a second dust removal cloth bag; wherein the casting dust collector and the hot work room dust collector are then sent to the vertical waste ash hopper through a pneumatic conveying tank, and finally output through waste ash humidifying and stirring.
