Description

Technical Field

[0001] The invention relates to the technical field of stone powder production devices, and in particular to a stone powder admixture preparation and screening device. Background Art

[0002] Stone powder is an admixture that can replace fly ash and be added to concrete. It can significantly reduce production costs without affecting product quality. The parent material of stone powder can be derived from slag ore. The process of preparing stone powder from ore requires crushing, grinding and refining, and screening steps. Among them, grinding and refining is beneficial to further refine the stone and obtain stone powder with better dispersion. At the same time, the particle size of stone powder is an important indicator of stone powder. Stone powder with uniform texture is required as an admixture to obtain concrete with stable quality.

[0003] Currently, most grinding equipment is quantitatively put in, and the refined material is stopped after a certain period of refining. The continuous operation performance is poor, and insufficient refining time will lead to a larger particle size distribution of the refined material. Too long grinding time leads to low efficiency, and it is impossible to accurately and efficiently screen out stone powder materials with suitable particle sizes.

[0004] In summary, we consider designing a stone powder preparation device that can operate continuously and has higher powder making efficiency, so as to accurately and efficiently screen out stone powder admixtures with suitable particle sizes; in view of this, we propose a stone powder admixture preparation screening device.

[0042] The screening part includes a powder bin 4 installed on a vertical fixing frame 3 and located above the motor body 2, and a receiving tray 6 installed in the powder bin 4, on which a refining component 8 is installed through the rotation of the motor body 2; in this embodiment, the powder bin 4 is vertically arranged and needs to be supported and installed by the vertical fixing frame 3; the refining component 8 is used to receive the stone powder admixture for refining and continuously screen out the stone powder admixture of qualified particle size through the receiving tray 6; it should be noted that the stone powder admixture to be refined in this embodiment is a particle that has been preliminarily crushed and powdered, and the purpose of the device is to further refine the particles to obtain stone powder with uniform particle size.

[0043] like Figure 3-Figure 5 As shown in the structure, the powder silo 4 in this embodiment includes a silo body 41 with a receiving hopper 42 installed on the top, and a feeding hole 421 is provided at the axis center of the receiving hopper 42. The stone powder admixture to be refined will fall into the silo body 41 below through the feeding hole 421; in this embodiment, a discharge port 43 and a cleaning window 44 located below the receiving tray 6 are provided on the silo body 41.

[0044] Specifically, the receiving tray 6 of this embodiment can be detachably installed in the bin body 41, and the receiving tray 6 includes a sieve plate 61 with sieve holes at the bottom, and a bearing 62 is installed at the axis of the sieve plate 61; Figure 4-Figure 6 In the structure shown, the refining component 8 includes a mounting base block 81 rotatably mounted on the material receiving tray 6 , and the mounting base block 81 is provided with a vertical cavity 8101 and four material guide holes 8102 for conducting and installing the grinding unit 82 .

[0045] It should be noted that in this embodiment, a scraper shaft wheel plate 7 is provided under the material receiving tray 6. The scraper shaft wheel plate 7 is coaxially installed in the vertical cavity 8101 through the bearing 62, and the shaft end of the scraper shaft wheel plate 7 is located below the material guide hole 8102. At the same time, the scraper shaft wheel plate 7 is coaxially connected to the output shaft of the motor body 2, and the refinement component 8 can be driven by the driving motor 2 to rotate and stir.

[0046] Specifically, Figure 8-Figure 11 As shown in the structure, in this embodiment, a rotating tray 811 and a vertical guide cylinder 812 are respectively provided at the bottom and the upper end of the mounting base block 81, and the upper end of the vertical guide cylinder 812 is connected and installed at the feeding hole 421 in this embodiment for guiding the material; in order to better convey the stone powder material and avoid the problem of feeding accumulation and blockage caused by the vertical structure, in this embodiment, an auger 5 installed at the shaft end of the scraper shaft wheel plate 7 is provided in the vertical guide cylinder 812, and the auger 5 is used to convey the stone powder admixture to be refined.

Ball milling beads are provided in the grinding bin 822. It should be noted that in order to screen the qualified particle size and continuously refine the stone powder material to reach the qualified particle size, the stone powder material is screened out in time to avoid over-refining. Therefore, the stone powder material is introduced into the grinding bin 822 through the discharge mesh hole 8211, and the stone powder material is rotated. The ball milling beads are used to grind the stone powder to a smaller particle size, which can be discharged through the sieve hole 8221 and the sieve plate 61. In other embodiments, the size of the sieve hole 8221 and the sieve hole on the sieve plate 61 can be adjusted according to the required particle size. In order to avoid the accumulation or blockage of the sieved materials, the present embodiment has protrusions 8222 evenly distributed on the wall of the grinding bin 822 and located on the adjacent sides of the sieve hole 8221, so that there are gaps between the powder materials, which will not be compressed and block the holes. At the same time, the protrusions 8222 can further provide stirring and dispersing force, so that the stone powder admixture with uniform texture can be discharged evenly.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
