Description

Technical Field

[0001] The utility model relates to the technical field of grinding mills, in particular to a metal grinding mill with a dustproof structure. Background Art

[0002] The working principle of the metal grinding machine is mainly to use high-speed rotating cutting tools to impact, cut, grind and other forces on metal fragments, thereby achieving the purpose of crushing metal.

[0003] The metal grinding mill mainly consists of a grinding mill host, a motor, a fan, a base, a feed port, a discharge port and other parts. The grinding mill host is equipped with a cutting tool, and the motor drives the tool to rotate at high speed through a transmission system. The base is used to fix the machine and play a stabilizing role. The feed port allows large pieces of metal to enter the machine, while the discharge port discharges the ground metal powder. At present, the metal grinding mill has a disadvantage. Due to the excessive wind force caused by the rotation of the grinding mill host, the metal and fine powder poured into the feed port by the operator are blown out of the feed port by the wind force caused by the rotation of the grinding mill host, resulting in the operating environment being affected by dust and unable to work normally. At the same time, the operator is in a dusty environment for a long time, which is at risk of causing occupational diseases. For this reason, a metal grinding mill with a dust-proof structure is proposed. Utility Model Content

[0004] The main purpose of the present invention is to provide a method for effectively solving the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a metal grinding mill with a dust-proof structure, comprising a grinding mill, a fan connected to the grinding mill, a motor connected to the grinding mill through a pulley, a cyclone powder collector connected to the grinding mill through a pipe, and a dust collector connected to the fan through a pipe, and the utility model is characterized in that: the grinding mill is provided with a double-closable feeding hopper, and the feeding hopper is provided with a plurality of movable flip plates.

[0006] Preferably, the fan is also connected to the cyclone powder collector through a pipeline.

[0007] Preferably, the flip plate includes flip plate A and flip plate B.

[0008] Preferably, a plurality of rotating shafts are provided in the feeding hopper, and shaft sleeves adapted to the rotating shafts are provided on the flip plate A and the flip plate B.

[0009] Preferably, silicone scrapers are provided at both ends of the flip plate A and one end of the flip plate B.

[0010] The utility model has the following beneficial effects: through the setting of the double-closed feeding hopper, the powder is prevented from being blown out through the feeding hopper when the operator is adding materials and during the grinding process of the grinding mill, resulting in excessive dust in the working environment, which seriously causes the operator to be unable to see the working area clearly and unable to work normally. At the same time, the operator is in an environment with excessive dust for a long time, which is at risk of inducing occupational diseases such as respiratory tract diseases; the setting of the rotating shaft and the shaft sleeve facilitates the rotation of the flip plate A and the flip plate B, and the weight of the material used during feeding causes the flip plate A and the flip plate B to rotate and feed, and reset after feeding, closing the flip plate A and the flip plate B, and at the same time, the flip plate A and the flip plate B are fed in turn. When one rotates to feed, the other is closed, effectively preventing dust from being blown out of the feeding hopper; the setting of the silicone scraper makes the sealing effect of the feeding hopper better.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-4As shown, a metal grinding mill with a dust-proof structure includes a grinding mill 1, a fan 2 connected to the grinding mill, a motor 3 connected to the grinding mill 1 through a pulley, a cyclone powder collector 4 connected to the grinding mill through a pipeline, and a dust collector 5 connected to the fan 2 through a pipeline. The characteristics of the metal grinding mill are that: the grinding mill 1 is provided with a double-closable feeding hopper 11, and the feeding hopper 11 is provided with a plurality of movable flip plates 6; the setting of the double-closed feeding hopper 11 prevents the operator from blowing out the powder through the feeding hopper 11 when adding materials and during the grinding process of the grinding mill 1, resulting in excessive dust in the working environment, which seriously causes the operator to be unable to see the working area clearly and unable to work normally. At the same time, the operator is in an environment with excessive dust for a long time, which is at risk of causing occupational diseases such as respiratory diseases.

[0018] In one embodiment, the fan 2 is also connected to the cyclone powder collector 4 through a pipeline.

[0019] In one embodiment, the flip plate 6 includes a flip plate A61 and a flip plate B62. The hopper 11 is provided with a plurality of rotating shafts 63. The flip plates A61 and B62 are provided with shaft sleeves 64 adapted to the rotating shafts 63. Silicone scrapers 65 are provided at both ends of the flip plate A61 and one end of the flip plate B62. The arrangement of the rotating shafts 63 and shaft sleeves 64 facilitates the rotation of the flip plates A61 and B62. During feeding, the weight of the material causes the flip plates A61 and B62 to rotate and feed. After feeding, the flip plates A61 and B62 are reset and closed. Furthermore, the flip plates A61 and B62 alternately feed material. When one rotates to feed, the other closes, effectively preventing dust from being blown out of the hopper 11. The provision of the silicone scrapers enhances the sealing effect of the hopper. The provision of the silicone scrapers 64 enhances the sealing effect of the hopper 11.

[0020] During the processing of the present invention, the operator first uses a tool to add the material into the feeding hopper 11, and the flip plate A61 is forced to rotate to feed the material. When the material enters the flip plate A61, the flip plate A61 is closed, and the material then enters the flip plate B62. When the material enters the flip plate B62, the flip plate B62 is closed, and then enters the grinding mill 1, and then the motor 3 drives the grinding mill 1 to grind. The ground powder is subjected to the action of the fan 2, so that the inner cavity of the grinding mill 1 is under negative pressure, so that the powder is sieved along the screening device at the top of the grinding mill 1 and then enters the cyclone powder collector 4 through the pipeline. After the powder evolves through the cyclone powder collector 4, the airflow returns to the fan 2 along the pipeline, and the residual air enters the dust collector 5 along the pipeline. Finally, the valve below the cyclone powder collector 4 is opened to collect the powder into the bag to complete the process.

[0021] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
