Detailed Description

The utility model discloses a screening device which is simple in structure, good in screening effect and convenient for collecting screened aggregates. In the description of the present embodiment, the terms "left" and "right" are used for convenience of understanding, and are only used for indicating the orientation of the present embodiment in the drawings, and should be understood in conjunction with the specific drawings. However, the structure of the present screening device is not limited to this orientation without specific reference.

The technical solution adopted in the present embodiment will be described below with reference to the accompanying drawings.

Referring to fig. 1, 2, 3 and 4, a building solid aggregate screening device includes a bracket 1 and a housing 2 mounted on the bracket 1, wherein the housing 2 is provided with a feed hopper 21 and a discharge hopper 22 which are longitudinally distributed. The hopper 21 is used for charging aggregate, and the hopper 22 is used for discharging aggregate. Further comprising: locate the screen frame 3 in the casing 2, lay the screen cloth on the screen frame 3. The screen frame 3 is obliquely arranged, the high point of the screen frame 3 is positioned below the feed hopper 21, and the low point of the screen frame 3 is positioned above the discharge hopper 22, so that the aggregate slides down along the surface of the screen under the action of gravity along the inclination direction. The screen frame 3 has a partition 4 perpendicular to the inclination direction at the middle position along the inclination direction, and a fine mesh screen 31 and a coarse mesh screen 32 are respectively provided at both sides of the partition 4, that is, the aggregates fed from the hopper 21 pass through the fine mesh screen 31 first and then pass through the coarse mesh screen 32. The screen cloth can be connected with the screen frame 3 by bolts or welding. It is obvious that the mesh size of the fine mesh screen 31 is smaller than that of the coarse mesh screen 32, and the specific size of the mesh size of the fine mesh screen and the coarse mesh screen can be changed according to the requirements of specific screening standards.

The material separating device further comprises a partition plate 5, one end of the partition plate 5 is connected to the bottom of the partition 4, the other end of the partition plate extends out of the discharge hopper 22, and the tail end of the partition plate extending out of the discharge hopper 22 is provided with a fork to form a fine material channel 51 and a coarse material channel 52 respectively.

As shown in the orientation of fig. 3: the aggregates fall into the fine-hole screen 31 after being fed into the feed hopper 21, small-particle aggregates in the aggregates are separated and screened, and large-particle aggregates continuously slide down to the coarse-hole screen 32 along the inclination direction and are separated and screened. Due to the presence of the partition 5, the small particle aggregates and the large particle aggregates are spatially separated, and finally, the small particle aggregates are discharged along the fine passage 51 on the right side, and the large particle aggregates are discharged along the coarse passage 52 on the left side.

In one embodiment, as shown in fig. 5, a dust cover 6 is provided on the housing 2, and the dust cover 6 may be fastened to the housing 2 by bolts. In the screening process, dust can be dissipated to the air to pollute the environment, and the dust cover 6 is arranged to effectively reduce the dissipation of the dust. Furthermore, a dust suction port 61 is formed in the dust cover 6, and a fan can be installed on the dust suction port 61 to extract dust from the dust cover 6 and introduce the dust into external dust collecting equipment.

To assist the feeding of aggregate from the screen, in one embodiment, a rapping mechanism is also mounted within the housing 2, the output end of which rapping mechanism raps both the fine mesh screen 31 and the coarse mesh screen 32. The rapping mechanism can be fixed at any position in the shell 2 through the mounting mechanism, and only the output end of the rapping mechanism needs to be in contact with the fine-hole screen mesh 31 and the coarse-hole screen mesh 32 during working. The number of the vibrating mechanisms is not limited, and a plurality of mechanisms may be provided to vibrate the fine mesh 31 and the coarse mesh 32, respectively.
