Problems solved by technology

The solid waste discharged by the current ventilation and dust removal method contains a large number of regenerated sand particles. These particles have a wide particle size distribution and the performance is consistent with ordinary thermal regenerated sand. However, due to current technical limitations, they cannot be utilized and discharged into nature.

Embodiment Construction

[0018] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0019] refer to figure 1 and figure 2 As shown, the housing 1 of the filtering device is provided with a hopper 2, and the hopper 2 is a bucket-shaped structure in which the outlet 7 is smaller than the inlet 6. The housing 1 is also provided with a compressed air inlet 3 and a particle outlet 4. The bottom of the housing 1 is also provided with a deflector 5, the relative angle between the deflector 5 and the bottom of the housing is 15 degrees, and the filter element 13 is a 4-layer filter core plate 12, according to the degree of filtration according to 30 mesh, 70 mesh, 100 mesh, The 140 meshes are arranged from coarse to fine and are connected by a connecting plate 11 . The connecting plate 11 is also provided with connecting bolts 10 matching the assembly holes 9 on the upper part of the housing 1 .

Abstract

The invention discloses a filtering device, which improves the filtering and reutilization of foundry regenerated sand waste by setting a special structure feeding hopper, introducing compressed air, adding deflector plates, and setting multi-layer filter core plates, etc., to achieve In order to improve the filtration efficiency and protect the environment.

Description

technical field [0001] The present invention relates to a filter device, in particular to a filter device for filtering discharges from a regenerated sand system in a foundry process. Background technique [0002] Most of the molding materials in sand casting are natural. The current environmental situation is becoming increasingly severe, and sand recycling technology has become a technology that foundry companies must master. Thermal regeneration technology is currently the sand regeneration technology with the highest regeneration rate, and the dust removal of thermal recycled sand is mainly carried out by means of ventilation and dust removal. The solid waste discharged by the current ventilation and dust removal method contains a large number of regenerated sand particles. These particles have a wide particle size distribution and the performance is consistent with ordinary thermal regenerated sand. However, due to current technical limitations, they cannot be utilized...
