Embodiment Construction

[0008] The embodiment is described in detail in conjunction with the accompanying drawings. It is installed in a screen box 1 with two layers of sieve plates, an upper resonant body 3 is installed under the upper sieve plate 2, and a lower resonant body is installed under the lower sieve plate 5. 6. The installation method of each layer of sieve plates is that one end is fixed on the screen box, and the other end is fixed on the resonator, and elastic parts 4 are evenly distributed between the upper and lower sieve plates and the upper and lower resonators. When working, there is a relative displacement gap between the screen box and the two layers of sieve plates, so that the two layers of sieve plates can bend and stretch while vibrating with the screen box, which can double the local vibration intensity of each sieve plate, effectively Improve screening efficiency, especially suitable for screening high-humidity viscous substances.

Abstract

The invention discloses a double-layer floating vibrating sieve. The double-layer floating vibrating sieve comprises a sieve box, an upper layer sieve plate and a lower layer sieve plate are installed inside the sieve box, a layer of resonators are installed below each layer sieve plate in a parallel mode, one end of each layer sieve plate is fixed on the sieve box, the other end of each layer sieve plate is fixed on the resonators, and elastic parts which are uniformly distributed are installed between the upper and lower layer sieve plates and the upper and lower layer resonators respectively. According to the double-layer floating vibrating sieve, the vibration strength of the upper and lower layer sieve plates is improved by resonance produced by the resonators between the upper and lower layer sieve plates and the sieve box, so that the screening efficiency can be effectively improved, energy can be saved, the hole blockage phenomena can be prevented, and the double-layer floating vibrating sieve is particularly applicable to treatment of materials which are much in moisture and high in viscidity.

Description

[0001] Technical field: [0002] The invention relates to screening, in particular to a double-layer floating vibrating screen suitable for screening materials with a lot of water and high viscosity. Background technique: [0003] The existing vibrating screen structure is that the sieve plate is directly fixed on the sieve box, and the material vibrates forward along with the sieve box on the sieve plate for screening during screening. When this traditional vibrating screen handles materials with high moisture content and high viscosity, it is prone to clogging, which affects the screening efficiency. Invention content: [0004] The purpose of the present invention is to provide a multi-layer floating vibration sieve suitable for screening materials with high moisture content and high viscosity, which is not easy to block holes and has high screening efficiency. [0005] The technical solution of the present invention is completed in the following manner, the double-...
