Description

Technical Field

[0001] The utility model relates to the technical field of cement concrete production, in particular to a sand screening device for producing cement concrete prefabricated components. Background Art

[0002] Precast concrete components are building components made in factories using concrete as the basic material. They include beams, slabs, columns, and building decoration accessories. When preparing precast concrete components, commonly used materials include sand, gravel, cement, etc.

[0003] In the prior art, a Chinese patent document with publication number CN213494936U and publication date June 22, 2021 is proposed: a sand screening device for the production of prefabricated cement concrete components, comprising at least one shell and a sieve plate obliquely arranged in the lower middle part of the shell, the top of the shell is connected to a second discharge channel, and the bottom of the shell is connected to a first discharge channel.

[0004] In order to solve the problem that manual sand screening is mostly used in the existing construction process, manual sand screening not only consumes manpower and financial resources, but also cannot guarantee the quality of sand. When screening a lot of sand, different screens are replaced according to the size of the sand, which not only wastes time, but also reduces the screening efficiency and brings inconvenience to people. The existing technology is to use a fan to control the air output of the fan, and use the fan to blow sand to achieve the screening of sand with different particle sizes. The combination of the utility model device can achieve the screening of sand with various particle sizes. The sand is screened mechanized and the manual workload is reduced. However, when the device is used, it is easy for sand and gravel to get stuck on the screening net when screening cement, which leads to the problem that the screening net is easily blocked after the sand and gravel get stuck.
