Magnetic powder stirring device with feeding structure and processing method

Abstract

The invention discloses a magnetic powder stirring device with a feeding structure and a processing method.The magnetic powder stirring device comprises a working box, a supporting sleeve and an outer barrel, the supporting sleeve is installed in the middle of the back of the working box, and the outer barrel is arranged in the middle of the top of the working box; an adjusting frame is slidably connected to the interior of the supporting sleeve, and a fastening knob is in threaded connection to the intersection of the adjusting frame and the supporting sleeve; a fixing clamp is installed at the top end of the adjusting frame, and a feeding cylinder is arranged in the fixing clamp. Through the arrangement of the feeding cylinder, a worker can add proper magnetic powder into the feeding cylinder, the control valve can adjust the output amount of the magnetic powder, so that the worker can perform selective discharging according to the amount of the required magnetic powder, and through the arrangement of the switch cover, external dust can be prevented from falling into the device to cause magnetic powder pollution; and through arrangement of an observation window, a worker can conveniently observe the interior of the feeding cylinder, so that the novelty of the device is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic powder stirring, in particular to a magnetic powder stirring device with a feeding structure and a processing method. Background technique [0002] Magnetic powder, a hard magnetic single-domain particle, granular magnetic powder should have the characteristics of single-domain particles, complete crystallization, smooth surface, suitable size, uniform particle size, and stable performance. When using it, the staff often use it first Stir, but the existing stirring structure still has certain deficiencies in actual use. [0003] The defect that existing a kind of magnetic powder stirring device and processing method exists is: [0004] 1. The comparative document CN214076071U discloses a magnetic powder stirring and feeding device, "comprising a support rod, a hopper is fixedly connected to the support rod through a bracket, and two crossbars are fixedly connected to the support rod, one of whic...

AI Technical Summary

Problems solved by technology

The magnetic powder stirring and feeding equipment, through the cooperation between the servo motor, the gear set, the reciprocating screw, the guide rod, and the slider, makes the wall scraping assembly reciprocate and linearly move along the vertical direction, and the wall scraping assembly moves the inner wall of the cylindrical material cavity At the same time, the stirring assembly and the auger rotate along the axis of the hopper, the inclined rod and the support rod stir the magnetic powder, the inclined scraper scrapes off the magnetic powder on the inner wall of the conical material chamber, and the auger can remove the magnetic powder in the hopper It is smoothly spirally sent out from the discharge pipe of the hopper, so that the magnetic powder in the hopper does not stick and the material is fed smoothly", but the device does not have a good feeding structure, which makes it difficult for the staff to control the amount of material added, which easily affects the mixing quality. ;

[0005] 2. The comparative document CN211476572U discloses a ferrite magnetic powder drying device capable of temporarily shutting down the furnace for heat preservation, "including a drying furnace, a sintering furnace and a circulation heater, and the drying furnace is equipped with a motor, a stirring mechanism, A cylinder and a push plate, a heating coil is arranged around the outer circumference of the drying furnace, a protective cover is arranged on the outer circumference of the heating coil, and the first air duct and the second air duct are connected to the protective cover. The other ends of the air duct, the first air duct and the second air duct are respectively connected with the sintering furnace. The utility model overcomes the deficiencies of the prior art, and is reasonable in design and convenient to use. Stir the magnetic powder in the drying furnace more evenly to achieve uniform drying of the magnetic powder. Use the high-temperature exhaust gas of the sintering furnace to temporarily keep the drying furnace shut down. While using the high-temperature exhaust gas reasonably, it can save re-drying The heating time during operation, thereby improving the drying efficiency and saving power", but the device does not have a good drying structure, making it difficult to effectively evaporate the moisture contained in the magnetic powder, thus affecting the quality of the finished product;

[0006] 3. The comparative document CN205164629U discloses a device for improving the uniformity of magnetic powder stirring, "including a mixing tank and a circulation device, the mixing tank includes an upper cylinder, a lower cylinder, a bucket cover and a discharge pipe; the center of the bucket cover is provided with a main Agitator, the main agitator includes a first motor, a main agitating shaft, and a main agitating blade; the side of the lower cylinder is provided with at least two secondary agitators, and the secondary agitator includes a second motor, a secondary agitating shaft, and a secondary agitating blade The circulation device includes a circulation pipe and an air pump. The bottom end of the circulation pipe is connected to the discharge pipe through a three-way valve, and the top end of the circulation pipe is connected to the barrel cover and communicates with the inside of the upper cylinder; the utility model provides an improved The efficiency of powder material stirring, the shortening of stirring time, and the uniformity of magnetic powder stirring are improved at the same time." work efficiency;

The utility model is simple in structure, low in cost, and can be adapted to different sizes of mixing tanks and installation shafts. However, the feeding structure and the overall structure of the device are difficult to disassemble quickly, which makes it difficult for staff to dismantle and clean it, and then in actual use. has certain limitations
