Description

Technical Field

[0001] This utility model relates to the field of metal powder stirring technology, and more specifically, to a stirring device for metallurgical hazardous waste powder. Background Technology

[0002] Metallurgical hazardous waste powder refers to fine particles of hazardous waste generated during the metallurgical process. Its sources are widespread, covering stages such as ore mining and smelting. It has a complex composition, containing heavy metals (such as lead and mercury) and toxic compounds. It possesses hazardous characteristics such as toxicity, corrosiveness, and flammability. Improper disposal can pollute soil and water bodies, harming the ecological environment and human health.

[0003] Patent CN220715654U discloses a metal powder mixing device, including a base, a fixed bracket connected to the top of the base, a universal coupling rotatably mounted on the top of the fixed bracket, a mixing tank rotatably mounted at one end of the universal coupling, stirring blades evenly distributed on one side of the inner wall of the mixing tank, an auxiliary unit connected to one end of the mixing tank, the auxiliary unit including an outer frame, a connecting plate connected to one side of the inner wall of the outer frame, a connecting shaft connected to the ends of the connecting plates that are close to each other, an inner frame connected to one end of the connecting shaft, a connecting frame rotatably mounted at the other end of the connecting shaft, a telescopic cylinder rotatably mounted at the bottom of the connecting frame, the bottom end of the telescopic cylinder rotatably mounted on the top of the base, and a drive motor connected to one side of the connecting frame.

[0036] Furthermore, the actuating frame 79 is fixedly installed on the outside of the upper grinding disc 74, and a brush is provided at the lower end of the actuating frame 79.

[0037] Furthermore, a triangular groove is provided on the inner side wall of the main mixing drum 1, and the triangular groove is connected to the discharge port. A filter screen 11 is fixedly installed in the triangular groove. By setting the filter screen 11 at the discharge port, the lumpy hazardous waste powder that is not evenly stirred can enter the connecting pipe 72.

[0038] The working principle of this utility model is as follows: In practical use, the operator puts hazardous waste powder into the main mixing drum 1 through the feed inlet. The motor 43 starts and drives the blade 42 to rotate via the rotating rod 41. The rotating blade 42 stirs the hazardous waste powder in the main mixing drum 1 and moves the powder to the position of the electromagnetic chuck 63. The electromagnetic chuck 63 is energized and attracts the magnetic substances in the hazardous waste powder. After the electromagnetic chuck 63 has attracted the powder for a period of time, the electric push rod 67 starts and drives the baffle 65 downward via the push plate 66. The baffle 65 separates the space between the main mixing drum 1 and the electromagnetic chuck 63. At this time, the operator's wrench 64 moves the electromagnetic chuck 63 via the mounting rod 62. Then, the power to the electromagnetic chuck 63 is turned off, and the magnetic hazardous waste powder attracted on the electromagnetic chuck 63... After falling into the auxiliary mixing drum 2 through platform 61, the electromagnetic chuck 63 is reset and energized. Subsequently, the baffle 65 is reset, making the space between the main mixing drum 1 and the electromagnetic chuck 63 connected. After the magnetic hazardous waste powder in the hazardous waste powder in the main mixing drum 1 is separated, motor 1 43 and motor 2 53 are started, driving blade 1 42 and blade 2 52 through rotating rod 1 41 and rotating rod 2 51 to stir the main mixing drum 1 and the auxiliary mixing drum 2. At the same time, motor 3 78 is started, driving gear 2 77 and gear 1 75 to rotate through rotating shaft 76. The upper grinding disc 74 rotates accordingly. The non-magnetic hazardous waste powder in the main mixing drum 1 enters the upper grinding disc 74 through the discharge port and connecting pipe 72. After being ground by the grinding grooves between the upper grinding disc 74 and the lower grinding disc 73, the ground hazardous waste powder is driven to the discharge port 3 by the actuating frame 79.

[0039] By setting a flip-up electromagnetic chuck 63 in the connecting frame 3, after the magnetic hazardous waste powder is adsorbed, the magnetic hazardous waste powder adsorbed on the electromagnetic chuck 63 is driven to the right side of the platform 61 and falls into the auxiliary stirring drum 2, thereby separating the magnetic powder and non-magnetic powder in the hazardous waste powder, which facilitates the subsequent recycling and treatment of the hazardous waste powder.

[0040] By setting through grooves on blade 42 and blade 52, it is possible to ensure that blade 42 and blade 52 can stir the hazardous waste powder, while preventing the hazardous waste powder from entering the main stirring drum 1 and the auxiliary stirring drum 2. This would prevent uneven stirring caused by the same type of powder accumulating in the gaps between blade 42 and blade 52.

[0041] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures, nor will they be described here.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
