Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering equipment manufacturing, in particular to an environmentally friendly construction engineering concrete dust-free rolling sand screening machine. Background Art

[0002] The drum sand screening machine imitates the working principle of manually screening sand with an inclined screen. It adopts a flat rolling screen drum and ensures that the material flow can be continuously rolled and screened for more than five circles between the multiple spiral blades in the screen drum, so that the sand material can roll and slide repeatedly to be fully dispersed and separated. It is different from the inclined rolling screen, which causes the large and small materials to push and bury each other, and the screening process is hurried; it is also different from the inclined vibrating screen, which causes the large and small materials to vibrate and mix.

[0003] After searching, among the related technologies, the patent document with authorization publication number CN218167699U discloses an environmentally friendly construction engineering concrete dust-free rolling sand screening machine, which belongs to the technical field of welding devices.

In the utility model, the left end of the filter is smaller in diameter than the right end to form a slope. When the filter rotates, the coarse sand that cannot be filtered can be discharged from the waste port.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that there are the following defects:

[0005] 1. Although the left end of the filter is smaller than the right end through the above-mentioned equipment to form a slope, when the filter rotates, the coarse sand that cannot be filtered can be discharged from the waste port, but the filter used in the above-mentioned is indirectly fixed, so there is inconvenience in disassembling and replacing the filter, so it is difficult to replace and clean the filter in the later stage.
