Description

Grit filter equipment for municipal works

Technical Field

The invention relates to the technical field of municipal engineering, in particular to a sand and stone filtering device for municipal engineering.

Background

Sand, which refers to a loose mixture of sand and gravel. Geology refers to mineral or rock particles with the particle size of 0.074-2 mm as sand, and those with the particle size larger than 2mm as gravel or breccia (the difference between the sand and the gravel is that the degree of rounding is different, and the detailed terms of conglomerate and sandstone can be seen). Different sandstone structures have larger difference, and some sandstone structures have uniform particle thickness and different sizes; some gravels have good grinding roundness of the fragments and some gravels have sharp edges and corners of the fragments. Sand is a loose material, but its particles are generally hard and chemically stable in the surface environment. Sandstone generally has stronger weather resistance, and particularly, siliconized quartz sandstone has hardness higher than granite.

In municipal works construction process, need use the grit usually, some require higher work progress, need be higher to the particle size requirement of grit, just need a filter equipment to filter the grit this moment.

Chinese patent (publication number: CN 210474612U) discloses a gravel filtering device for municipal engineering, which comprises a placing table and a funnel, wherein a first limiting block is fixedly arranged at the left end and the right end of the upper end of the placing table, a control panel is fixedly arranged at the left end of the placing table, a second limiting block is fixedly arranged at the upper end of the left side and the upper end of the right side of the funnel, the first limiting block and the second limiting block are fixedly connected through a spring, and a filter screen is horizontally arranged at the top of the funnel. The device is through the vibrating motor on spring and the funnel between first stopper and the second stopper, through installing the second stopper on the funnel, through placing the first stopper of bench installation, thereby avoid the spring to take place the skew when controlling and rocking, through installing vibrating motor on the funnel, thereby come to filter the grit in the filter screen through vibrating funnel and separate, thereby cross and filter out the stone, effectual improvement grit filtration efficiency, and reduce the amount of labour, and is comparatively practical, be fit for extensively promoting and using, but the device's filter effect is general, consequently, need modify the device.
