Sand-stone sieve plate device for industry

Abstract

The invention discloses a sand-stone sieve plate device for the industry. The sand-stone sieve plate device for the industry comprises a bottom plate, a first vibration unit, a sieve frame, a second vibration unit and a power unit, wherein the first vibration unit comprises first fixed plates, first springs and first slide tables; two first fixed plates are arranged, and arranged at the front sideand the rear side of the right end of the upper surface of the bottom plate separately, and through grooves are formed in the side surfaces of the two first fixed plates separately; two first slide tables are arranged; the side surfaces of the two first slide tables are slidably connected with the sidewalls of the through grooves in the side surfaces of the two first fixed plates separately; fourfirst springs are arranged; the upper ends of the two first springs at the upper side are fixedly connected with the tops of the through grooves in the side surfaces of the two first fixed plates separately; and the lower ends of the two first springs at the upper side are fixedly connected with the upper surfaces of the two first slide tables separately. The sand-stone sieve plate device for theindustry is good in sieving effect and low in sieving efficiency, and thorough sand-stone separation after sieving is achieved.

Description

technical field [0001] The invention relates to the technical field of sand and gravel screening equipment, in particular to an industrial sand and gravel sieve plate device. Background technique [0002] Sandstone refers to the loose mixture of sand grains and crushed stones. In geology, mineral or rock particles with a particle size of 0.074-2mm are called sand, and those with a particle size larger than 2mm are called gravel or breccia. The sand and gravel should be screened during the process. The existing screening equipment is mainly screened through a rotating screen. This screening device has poor screening effect and low screening efficiency, and the screened sand and gravel are easily mixed together. , which seriously affects the efficiency of sand screening. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an industrial sand and gravel sieve plate device, which has goo...
