Description

Technical Field

[0001] This utility model relates to the field of iron powder processing technology, specifically to an iron powder feeding device. Background Technology

[0002] Iron powder is an indispensable metal raw material for the national economy, especially the machinery manufacturing industry. Iron powder is mainly used in powder metallurgy, welding electrode production, flame cutting and cleaning, magnetic fields, electrostatic copying, power industry, food industry, pharmaceuticals, chemical industry and other industries. Iron powder feeding devices are widely used in metallurgy, chemical industry, 3D printing, powder metallurgy and other fields for precise delivery of iron powder and other metal powders.

[0003] Traditional iron powder feeding devices are prone to moisture absorption and clumping or static electricity adsorption, leading to uneven discharge, blockage, and affecting feeding accuracy. At the same time, failure to remove static electricity in time can also cause safety problems. Furthermore, the traditional stirring structure is too simple, which makes it easy for iron powder to be stirred unevenly. To address these issues, we propose an iron powder feeding device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an iron powder feeding device that effectively prevents iron powder from agglomerating and clogging through the synergistic effect of spiral conveying and dynamic stirring; it integrates dehumidification, static electricity removal and intelligent control system to adjust the feeding process in real time, ensuring the flowability and feeding accuracy of iron powder; it is applicable to metallurgy, chemical industry and other fields, significantly improves feeding stability and production efficiency, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an iron powder feeding device, comprising a tank and a fixed shaft;

[0006] Tank body: The top surface and the bottom surface of the tank cover are installed in a corresponding fit. A motor is fixed in the middle of the top surface of the tank cover. The output shaft of the motor is connected to the top of the coupling. A discharge shell is fixed in the bottom surface of the tank body. The discharge shell is connected to the discharge pipe on the bottom surface of the tank body. The fixed shaft is rotatably installed in the shaft hole on the top surface of the discharge shell. A threaded conveying blade is fixed on the outside of the fixed shaft. The threaded conveying blade is located inside the discharge shell. Feed grooves are evenly opened on the surface of the discharge shell. A processing unit is provided inside the tank body.

[0007] It also includes a controller, which is installed on the surface of the tank. The input terminal of the motor is electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0008] The coupling connects the motor output shaft to the fixed shaft. Iron powder enters the discharge shell through the feed chute, and the fixed shaft drives the threaded conveyor rod to rotate to quantitatively convey the iron powder.

[0009] Furthermore, the processing unit includes a fixed disk, a support plate, rubber stirring rods, a gear ring, a gear, and a rotating shaft. The support plate is fixed to the outside of the fixed shaft. The rotating shaft is rotatably installed in two shaft holes on the surface of the support plate. The bottom end of the rotating shaft is connected to the center of the top surface of the fixed disk. Rubber stirring rods are arranged in a circular array around the center axis on the bottom surface of the fixed disk. A gear is installed at the top of the rotating shaft. The gear ring is fixed to the bottom surface of the can lid. The gear ring meshes with the gear. The meshing of the gear ring and the gear allows the rubber stirring rods to rotate on their own axis while revolving around the center, thereby efficiently stirring the iron powder to solve the problem of iron powder clumping, thus ensuring unobstructed feeding chute and avoiding blockage of the discharge shell.

[0010] Furthermore, the processing unit also includes a dehumidifying shell, a filter box, and a negative pressure fan. There are two dehumidifying shells, which are respectively fixed at both ends of the outer side of the tank. The interior of the dehumidifying shell is connected to the air groove inside the tank. The negative pressure fan is installed on the surface of the dehumidifying shell. The filter box is inserted into the slot on the front side of the dehumidifying shell. The input end of the negative pressure fan is electrically connected to the output end of the controller. The negative pressure fan draws the moisture in the tank to the dehumidifying shell, where the moisture is absorbed by the dehumidifying cotton inside the filter box to avoid the problem of iron powder oxidation and clumping due to moisture.

[0011] Furthermore, the processing unit also includes a mounting base, an antistatic ion bar, and an air pump. The mounting base is fixed to the front side of the top surface of the can lid, and the antistatic ion bar is placed inside the mounting base. The air outlet on the bottom surface of the antistatic ion bar is inserted into the vent hole on the top surface of the can lid. The air pump is fixed to the rear side of the top surface of the can lid, and the air outlet pipe of the air pump is connected to the air inlet on the top surface of the antistatic ion bar. The input ends of the antistatic ion bar and the air pump are electrically connected to the output end of the controller. When the air pump is started, airflow is injected into the antistatic ion bar and enters the can body to neutralize the static electricity on the surface of the iron powder to reduce adsorption and thus improve the fluidity of the iron powder.

[0012] Furthermore, it also includes a closed cover and an electric telescopic rod. There are two electric telescopic rods, which are fixed to the top surface of the discharge shell on the left and right sides respectively. The top of the electric telescopic rod is connected to one side of the top surface inside the closed cover. The closed cover is slidably installed on the outer side of the discharge shell. The input end of the electric telescopic rod is electrically connected to the output end of the controller. The closed cover, which is raised and lowered, controls the exposed area of ​​the feed chute, flexibly adapts to the feeding needs of iron powder with different particle sizes, and can also be closed to improve the sealing performance.

[0013] Furthermore, it also includes a level sensor and a humidity sensor. The level sensor is fixed to the bottom of the tank, and the humidity sensor is installed on the front side of the tank. The output terminals of the level sensor and the humidity sensor are electrically connected to the input terminal of the controller. The level sensor can detect the remaining amount of iron powder inside the tank, which facilitates timely addition. The humidity sensor can detect the humidity inside the tank in real time.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This iron powder feeding device has the following advantages:

[0015] 1. The motor output shaft is connected to the fixed shaft via a coupling. Iron powder enters the discharge shell through the feed chute. The fixed shaft drives the threaded conveyor rod to rotate and quantitatively convey the iron powder. The lifting and lowering enclosure controls the exposed area of ​​the feed chute, flexibly adapting to the feeding needs of iron powder of different particle sizes. It can also be closed to improve the sealing performance.

[0016] 2. The meshing of the gear ring and gears allows the rubber stirring rod to rotate on its own axis while revolving around the central axis, thus efficiently stirring the iron powder to solve the problem of iron powder clumping. This ensures unobstructed feeding chute and prevents blockage of the discharge shell. The negative pressure fan draws the moisture in the tank to the dehumidification shell, where it is absorbed by the dehumidifying cotton inside the filter box to prevent iron powder oxidation and clumping due to moisture. The air pump is started to inject airflow into the antistatic ion bar and into the tank to neutralize the static electricity on the surface of the iron powder, reducing adsorption and improving the flowability of the iron powder.
