Description

Technical Field

[0001] The invention relates to the technical field of mortar production, and in particular to a powder screening system. Background Art

[0002] Sand and gravel are one of the materials used in the field of building materials. In the specific production process, the sand and gravel production system is often required to crush, screen, wash, store and transport the raw materials of sand and gravel. The existing sand and gravel production system includes a crusher, a conveyor, a screening device, and a cleaning device. During production, the raw materials of sand and gravel are first crushed by a crusher. The crushed sand and gravel will be transported to the screening device through a conveyor and sorted into sand and gravel of different particle sizes.

[0003] In the prior art, the sand and gravel screening device has only one layer of screen for screening, so the screening result is not detailed enough and cannot meet the needs of being used in multiple places according to the diameter of the sand and gravel. In addition, the existing screening device does not screen sufficiently, resulting in low screening efficiency. Summary of the invention

[0004] The present invention aims to provide a powder screening system which can improve the efficiency of sand and gravel screening and increase the amount of powder required for screening according to demand.

[0043] The cylindrical vibrating screen 1 of this embodiment has a first vibrating screen space, a second vibrating screen space and a third vibrating screen space. When sand and gravel are put into the cylindrical vibrating screen 1, they will pass through the first vibrating screen space, the second vibrating screen space and the third vibrating screen space in sequence along the height direction.

[0045] The screening module separates the sand and gravel into two types through the second coarse vibration screen and the second fine vibration screen, so as to meet the needs of sand and gravel with different diameters under different working conditions; at the same time, the linear vibrating screen 2 is used to perform vibration separation in an inclined state from top to bottom, so that the gravity of the sand and gravel itself is used to complete the separation state under the drive of vibration, effectively improving the screening efficiency.

The bottom end of the main output pipeline is connected to the first branch pipeline 4 and the second branch pipeline 5 respectively. The first branch pipeline 4 is directed toward the standby screening module, and the second branch pipeline 5 is directed toward the main screening module.

[0052] Sand and gravel are transported to the first branch pipe 4 and the second branch pipe 5 through the main conveying pipe 3. The first branch pipe 4 inputs the sand and gravel into the standby screening module, and the sand and gravel are screened at different levels by the standby screening module to obtain the required amount of powder. The second branch pipe 5 inputs the sand and gravel into the main screening module, and the sand and gravel are screened at different levels by the main screening module to obtain the required amount of powder. Therefore, screening is performed simultaneously by the main screening module and the standby screening module to improve the screening efficiency.

Among them, the main screening module screens sand and gravel with coarse diameter, medium diameter and fine diameter to obtain powder with fine diameter, and the standby screening module screens sand and gravel with coarse diameter and fine diameter to obtain powder with fine diameter.
