[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) in a certain proportion and mixed to obtain cement concrete, also called ordinary concrete, which is widely used in civil engineering.

[0003] For example, a Chinese patent discloses: a grinding device for producing special powder for concrete, publication number: CN218902000U, "comprising a crushing box, wherein a rolling vibration mechanism is arranged inside the crushing box, wherein the rolling vibration mechanism comprises a rotating motor fixedly connected to the left side of the crushing box, wherein the output shaft of the rotating motor is fixedly connected to a threaded rod rotatably connected to the right inner wall of the crushing box, wherein the outer side of the threaded rod is threadedly connected to a moving block, wherein a moving rod is fixedly installed at the bottom of the moving block, and through the rolling vibration mechanism, a plurality of rolling cylinders are driven to roll and grind back and forth under the action of the rotating motor, thereby greatly reducing the grinding time and improving the grinding efficiency. After the grinding is completed, the ground powder is shaken off the screen plate by the vibration motor, thereby facilitating and better collecting the ground powder and avoiding the concrete powder from staying and getting stuck on the grinding device and causing damage". However, during the material collection process, the discharge pipe is prone to blockage, which makes it inconvenient to collect the ground concrete powder. In view of the above problems, we propose a powder refining device for concrete production. Utility Model Content

A feed pipe 11 is fixedly installed on the upper end of the refining cylinder 1. The raw materials are put into the refining cylinder 1 from the feed pipe 11. The motor 5 is started to rotate the shaft 51. The grinding roller 4 is driven to rotate by the rotation of the shaft 51. The input raw materials are ground by the rotation of the grinding roller 4 and the raw materials can be ground into powder. During the grinding process, the powder falls into the discharge disc 2 through the gap between the grinding roller 4 and the refining cylinder 1, completing the collection of the powder. The vibration motor 22 is started, and the discharge disc 2 is vibrated under the action of the spring 32, so that the powder collected in the discharge disc 2 can be smoothly discharged from the discharge pipe 21, alleviating the blockage of the discharge pipe 21, facilitating better collection of concrete powder, and achieving better use effect.

[0024] The bottom surface of the inner wall of the discharge tray 2 is inclined toward the center of the discharge tray 2. The discharge tray 2 is located between the four supporting legs 3. A baffle 31 is fixedly installed on each supporting leg 3. A spring 32 is installed on each baffle 31. Each sliding sleeve 7 is fixedly connected to the baffle 31 through a spring 32. The four supporting legs 3 are fixedly connected to the bottom end of the refining cylinder 1. The bottom surface of the inner wall of the discharge tray 2 is inclined toward the center of the discharge tray 2, so that the concrete powder can be discharged from the discharge pipe 21 more smoothly.

[0025] Working principle:

[0026] The first step is to put the raw material into the refining cylinder 1 from the feed pipe 11, start the motor 5, make the rotating shaft 51 rotate, and the rotation of the rotating shaft 51 drives the grinding roller 4 to rotate. The rotation of the grinding roller 4 will grind the input raw material and can grind the raw material into powder. During the grinding process, the powder falls into the discharge tray 2 through the gap between the grinding roller 4 and the refining cylinder 1, completing the collection of the powder, and starting the vibration motor 22. Under the action of the spring 32, the discharge tray 2 vibrates, so that the powder collected in the discharge tray 2 can be smoothly discharged from the discharge pipe 21, thereby alleviating the blockage of the discharge pipe 21, facilitating better collection of concrete powder, and achieving better use effect.

[0027] In the second step, the bottom surface of the inner wall of the discharge tray 2 is tilted toward the center of the discharge tray 2, so that the concrete powder can be discharged from the discharge pipe 21 more smoothly.
