Description

Technical Field

[0001] The utility model relates to the technical field of raw material mixing, in particular to a powder material stirring and mixing device for impact bricks. Background Art

[0002] When the impact brick is prepared, its main raw materials are brown corundum, fused corundum, fused magnesia and a binder; its secondary raw materials are corundum powder, fused spinel powder and activated alumina; the brown corundum, fused white corundum and fused magnesia prepared above are combined and mixed evenly to obtain a mixed aggregate, and a binder is added, and the corundum powder, fused spinel powder and activated alumina prepared above are combined and mixed evenly to obtain an active composite spinel micro powder;

[0003] When powdered materials are mixed, due to their small particle size and the presence of a certain amount of moisture inside the materials, the materials are easily adhered to the inner wall of the mixing device. When discharging, the powdered materials adhered to the inner wall are difficult to be discharged normally under the action of gravity, affecting the discharging.

[0004] Therefore, a device for stirring and mixing powdered materials for impact bricks is needed to overcome the occurrence of the above problems. Utility Model Content

[0005] In order to solve the above problems, the embodiment of the utility model provides a powder material stirring and mixing device for impact bricks, which achieves the purpose of solving the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a powder material stirring and mixing device for impact bricks, comprising a mixing bin, a spiral stirring frame is rotatably connected to the inside of the mixing bin, a motor for driving the spiral stirring frame to rotate is arranged at one end of the mixing bin, a discharge port is arranged on the mixing bin, a scraper frame is arranged inside the mixing bin, the scraper frame is fitted on one side of the inner wall of the mixing bin, and a driving mechanism for driving the scraper frame to move is arranged on the mixing bin.

[0007] As a further improvement of the above technical solution:

[0008] The driving mechanism includes a guide rail fixedly connected to one side of the mixing bin, a screw rod rotatably connected to the inside of the guide rail, a motor 2 arranged at one end of the guide rail for driving the screw rod to rotate, and a slider threadedly connected to the outside of the screw rod and slidably arranged inside the guide rail; the slider is fixedly connected to the scraper frame.

[0009] A through groove is provided inside the scraping frame, and the spiral stirring frame is sleeved inside the through groove.

[0010] Brush bristles are arranged inside the through groove.

[0011] One end of the mixing bin is rotatably connected to a baffle plate covering one side of the discharge port.

[0012] The beneficial effects of the embodiments of the utility model are:

[0013] After the raw materials are stirred and mixed, the materials are discharged from the discharge port. After the materials are discharged, the driving mechanism drives the scraper frame to reciprocate inside the mixing bin, so that the scraper frame can scrape off the powdered materials adhering to the inner wall of the mixing bin. That is, when discharging, the scraper frame moves under the drive of the driving mechanism to scrape off the powdered materials on the inner wall of the mixing bin, so that the powdered materials adhering to the inner wall can be discharged normally.

[0014] By arranging the bristles, after the discharge is completed, the scraping frame moves inside the mixing bin to scrape off the powdered material adhering to the inner wall. At the same time, the motor drives the spiral stirring frame to rotate, so that the spiral stirring frame comes into contact with the bristles, and the powdered material adhering to the spiral stirring frame is brushed off by the bristles. That is, the present application can also clean the spiral stirring frame to prevent the material from adhering to the spiral stirring frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] See also Figures 1 to 3The embodiment of the utility model discloses a powder material stirring and mixing device for impact bricks, comprising a mixing bin 1, wherein a spiral stirring frame 2 is rotatably connected inside the mixing bin 1, a motor 3 for driving the spiral stirring frame 2 to rotate is arranged at one end of the mixing bin 1, a material discharge port 4 is arranged on the mixing bin 1, and two material discharge ports 4 are arranged. When stirring and mixing, the raw materials are added into the mixing bin 1 from the top opening of the mixing bin 1, the motor 3 is started to drive the spiral stirring frame 2 to rotate, so as to mix the raw materials, and the raw materials are discharged through the material discharge port 4 after the mixing is completed, a scraping frame 5 is arranged inside the mixing bin 1, and the scraping frame 5 is arranged on one side of the inner wall of the mixing bin 1, and a driving mechanism 6 for driving the scraping frame 5 to move is arranged on the mixing bin 1;

[0021] The spiral stirring frame 2 is composed of a rotating shaft and a spiral blade fixedly connected to the rotating shaft. Since the present application is aimed at stirring and mixing powdered materials, the pitch of the spiral blade can be appropriately increased so that the spiral blade can better stir the materials when rotating, thereby facilitating mixing. When mixing, in order to prevent the material from leaking out of the mixing bin 1 and to ensure the mixing effect, the best effect is achieved when the amount of material added is 30%-50% of the volume of the mixing bin 1.

After the materials are discharged, the drive mechanism 6 drives the scraper frame 5 to reciprocate inside the mixing bin 1, so that the scraper frame 5 can scrape off the powdered materials adhering to the inner wall of the mixing bin 1. That is, when discharging, the scraper frame 5 moves under the drive of the drive mechanism 6 to scrape off the powdered materials on the inner wall of the mixing bin 1, so that the powdered materials adhering to the inner wall can be discharged normally.
