Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill for preparing iron powder. Background Art

[0002] Iron powder, an aggregate of iron particles less than 1mm in size, is the primary raw material for powder metallurgy, used in the manufacture of mechanical parts. Mechanical parts are typically formed through processes such as casting, forging, stamping, and welding. These processing methods share the characteristics of low material utilization, high costs, and increasingly significant environmental and workplace hygiene issues. In contrast, powder metallurgy offers advantages in saving materials and labor, facilitating automation and mass production, and significantly improving the working environment. Ore powder generally refers to the powder obtained by crushing mined ore. Processing ore powder into iron powder requires the use of a ball mill for iron powder preparation.

[0003] The working principle of the existing ball mill is to process the material by dropping internal steel balls from a high place to hit the material. During the material feeding process, due to the small material particles, they are easy to adhere to the inner wall of the ball mill shell, resulting in incomplete feeding during the feeding process. Therefore, a ball mill for iron powder preparation is proposed to address the above problem. Utility Model Content

[0004] The purpose of the present invention is to provide a ball mill for preparing iron powder to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] As an optional solution of the ball mill for preparing iron powder described in the utility model, wherein: a ball mill for preparing iron powder comprises a base, a ball mill housing and a driving device;

[0007] A ball mill housing is installed above the base, and a driving device fixedly connected to the base is provided on one side of the ball mill housing, and a protective cover fixedly connected to the base is provided below the ball mill housing;

[0008] The outer side of the ball mill housing is also fixedly connected with evenly distributed fixing plates;

[0009] The interior of the ball mill housing is fixedly connected with evenly distributed protrusions;

[0010] A plurality of steel balls are also provided inside the ball mill housing;

[0011] A knocking and unloading mechanism is also installed above the base;

[0012] The knocking blanking mechanism includes a fixed frame, a motor and a rotating plate. The bottom of the fixed frame is fixedly connected to the base. The motor is installed inside the fixed frame, and the end of the motor's main shaft is fixedly connected to the rotating plate. The other end of the rotating plate is fixedly connected to a connecting pin, and the outer side of the connecting pin is rotatably connected to the knocking plate.

[0013] The working principle of the existing ball mill is to hit the material by dropping the internal steel balls from a high place, so as to realize the material processing work. When the material is unloading, the material particles are small and easily adhere to the inner wall of the ball mill shell. There is a problem of incomplete unloading during the unloading process. During the unloading process, the rotating plate is driven to rotate by starting the motor, and the rotating plate drives the connecting pin to rotate, and the connecting pin drives the knocking plate to rotate, so that the knocking plate knocks the fixed plate, and at this time drives the ball mill shell to vibrate, which helps the material attached to the inner wall of the ball mill shell to vibrate and fall, ensuring that the material falls fully.

[0014] As an optional solution of the ball mill for preparing iron powder described in the utility model, a groove is provided on the side of the fixing frame facing the ball mill housing.

[0015] When the ball mill shell is in use, its rotating plate will not rotate, and the knocking plate is in a free hanging state. At this time, it will not contact the fixed plate and will not affect the normal rotation of the ball mill shell. The provided groove can ensure the normal rotation of the fixed plate.

[0016] As an optional solution of the ball mill for preparing iron powder described in the utility model, a collecting frame is slidably connected to the interior of the fixed frame, and a guide plate is fixedly connected to one side of the collecting frame.

[0017] As an optional solution of the ball mill for preparing iron powder described in the utility model, the upper end surface of the guide plate is arranged to be inclined.

[0018] As an optional solution of the ball mill for preparing iron powder described in the utility model, a feeding chute is further provided inside the guide plate.

[0019] During use, dust impurities on the surface of the ball mill shell or other external impurities may fall into the fixed frame. At this time, the collection frame can be used to collect them, and the guide plate serves as a guide, and the discharge chute can ensure the smooth rotation of the fixed plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] During the unloading process, the utility model starts the motor to drive the rotating plate to rotate, the rotating plate drives the connecting pin to rotate, and the connecting pin drives the knocking plate to rotate, so that the knocking plate knocks the fixed plate, and at this time drives the ball mill shell to vibrate, which helps the material attached to the inner wall of the ball mill shell to vibrate and fall, ensuring that the material falls fully;

[0022] When the ball mill shell is in use, the rotating plate will not rotate, and the knocking plate is in a free hanging state. At this time, it will not contact the fixed plate and will not affect the normal rotation of the ball mill shell. The grooves provided can ensure the normal rotation of the fixed plate.

[0023] During use, dust and impurities on the surface of the ball mill shell or other external impurities may fall into the fixed frame. In this case, the collection frame can be used to collect them, and the guide plate plays a guiding role. The discharge chute can ensure the smooth rotation of the fixed plate.
