Automatic and efficient multistage rotary sand sieving machine and production method thereof

Abstract

The invention discloses an automatic and efficient multistage rotary sand sieving machine which comprises a barrel body, a material distribution base and a control motor. A rotary barrel and a conical barrel are mounted at the lower end of the barrel body in sequence. A material distribution board is arranged between the material distribution base in the barrel body and a feeding hopper which is located at the top end of the material distribution base. A filter screen is arranged in an air outlet pipe located at the top end of the barrel body. A rotary sleeve wheel located on the rotary barrel is connected with the control motor through a driving wheel. A plurality of sand outlet barrels are arranged in the conical barrel from inside to outside in sequence and are fixedly connected onto mesh sieves and sliding boards which are both located on the inner wall of the rotary barrel through rotary joints respectively, a plurality of vibrating boards are arranged on the inner wall of the rotary barrel, and a pneumatic pipe located at the lower end of the material distribution base is connected with an air nozzle and an air inlet pipe. The automatic and efficient multistage rotary sand sieving machine is simple to operate and can conduct multistage sieving on mixed sand automatically without blocking sieving holes easily; has a high sieving efficiency and fast sieving speed and small pollution, thereby effectively improving the working environment .

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to an automatic high-efficiency multi-stage rotary sand screener and a manufacturing method thereof. Background technique [0002] Sub-projects such as masonry, plastering and inlaying use a large amount of sand, and at the same time have strict requirements on the quality and particle size of the sand. Existing sand screening machines are generally open-type vibrating screens. Due to the relatively concentrated loading of materials during the work process, the discharge speed of large-grained gravel is too fast, resulting in poor use of the device and low work efficiency; Blocking the sieve holes makes it impossible to screen, and the screening effect of the device is weakened; and in the screening process, the dust is very large, so the open vibrating screen will cause pollution and affect the health of the operators.
