Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a ball mill with an automatic cleaning function. Background Technology

[0002] In the process of grinding materials, dust and residual materials tend to accumulate on the inner wall of the cylinder, the grinding media, and dead corners of the traditional ball mill. Long-term accumulation will cause dust to be raised when the raw material comes into contact with the feed hopper of the ball mill during the feeding stage of the working process, which will lead to a decline in the air quality of the surrounding environment, pollute the surrounding environment, increase the dust concentration in the workplace, and harm the health of workers.

[0003] Meanwhile, the dust settling on the ball mill surface not only corrodes the mill but also exacerbates wear on the mill's gears and toothed discs during meshing, interfering with the mill's operation and affecting its lifespan. Cross-contamination residues from dust affect the purity of subsequent batches of material; dust overflow makes it difficult for traditional dust removal systems to fully cover the material, polluting the environment. Current technologies, such as water spraying or airflow cleaning, are mostly single-method solutions, resulting in incomplete cleaning, water waste, or secondary dust re-entrainment.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 like Figure 1-4 As shown, this embodiment provides a ball mill with an automatic cleaning function, including a rotating cylinder 1, a support 10, an air supply mechanism, and a water spraying mechanism.

[0015] The support bracket 10 is used to support the entire ball mill structure.

[0016] The rotating cylinder 1 is rotatably mounted on the support 10; the rotating cylinder 1 is the main grinding container of the ball mill, used to load materials and grinding media (such as steel balls). The rotating cylinder 1 is provided with a feed inlet and a discharge outlet.

[0017] The support 10 has a base at the bottom, and a large gear 2 is provided on the outside of one end of the rotating cylinder 1. A small gear 31 is provided on the top of the base through the support. The small gear 31 is meshed with the large gear 2. The end of the small gear 31 away from the rotating cylinder 1 is connected to the output end of the servo motor 3 on the support through a coupling. The air supply mechanism is located on one side of the small gear 31.

[0018] The large gear 2 is fixed to the outside of the rotating cylinder 1 and is used to transmit power.

[0019] Servo motor 3 is the power source that drives the ball mill.

[0020] The pinion 31 meshes with the large gear 2, transmitting the power of the servo motor 3 to the rotating cylinder 1.

[0021] The air supply mechanism includes a blower 41, a bag filter 42, an air duct 43, and a branch pipe 44. The blower 41 and the bag filter 42 are connected by the air duct 43. A branch pipe 44 is horizontally arranged at the other end of the connection between the air duct 43 and the bag filter 42, and the branch pipe 44 faces the bottom of the rotating cylinder 1. The blower 41 provides high-pressure airflow. The bag filter 42 collects dust to prevent pollution. The air duct 43 connects the blower 41 and the bag filter 42. The branch pipe 44 guides the airflow to the bottom of the rotating cylinder 1 to blow away residual dust.

[0022] The water spray mechanism includes a water tank 51, a high-pressure pump 52, a water inlet channel 53, and a nozzle holder 54. The water tank 51 is installed on the opposite side from the blower 41. The high-pressure pump 52 is connected between the water tank 51 and the water inlet channel 53. The water inlet channel 53 is arranged in a spiral shape around the bottom area of ​​the rotating cylinder 1. The nozzle holder 54 is installed at the outlet of the water inlet channel 53 and has multiple nozzles mounted on it. The water spray mechanism is used to rinse away stubborn residues. The water tank 51 stores cleaning water, and the high-pressure pump 52 provides high-pressure water flow. The spiral-shaped water inlet channel 53 surrounds the bottom of the rotating cylinder 1 to ensure complete coverage. The nozzle holder 54 has multiple nozzles that spray water at multiple angles.

[0023] The nozzle has several spray ports that communicate with the water inlet channel 53, and the spray ports are distributed at multiple angles on the nozzle.

[0024] During operation, in the grinding stage, the servo motor 3 drives the pinion 31, which in turn drives the large gear disk 2 to rotate the rotating cylinder 1, and the material is crushed by the grinding media inside the cylinder.

[0025] During the automatic cleaning phase, the air supply mechanism operates, with blower 41 generating high-pressure airflow that blows through duct 43 and branch pipe 44 to the bottom of the rotating cylinder 1, removing loose dust. The dust is collected by bag filter 42 to prevent environmental pollution. The water spray mechanism operates, with high-pressure pump 52 drawing water from water tank 51 and delivering it to the water inlet channel 53. Water is sprayed through multi-angle nozzles on nozzle seat 54, covering the bottom of the cylinder and rinsing away residual material. After water spraying, the air supply mechanism assists in drying residual moisture to prevent rust or clumping.

[0026] Efficient automatic cleaning is achieved through an air supply mechanism and a water spray mechanism: the air supply mechanism blows directional air through branch pipes to the bottom of the rotating cylinder, and works in conjunction with a bag filter to collect dust in real time, preventing dust spread; the water spray mechanism covers the bottom of the cylinder with a twisted water inlet channel and multi-angle nozzles, and high-pressure water jets remove stubborn residues. After spraying, the air supply mechanism assists in drying, reducing water stains. The twisted water inlet channel and multi-angle distribution of the spray nozzles, along with the dual water and air cleaning mode, ensure thorough cleaning without dead angles.

[0027] The above description is merely an illustrative example of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, all of which should fall within the protection scope of this utility model.
