Used sand flow state cooling dust removal device

Abstract

The invention discloses a used sand flow state cooling dust removal device, which comprises a tower body, a sand-sliding device and a ventilation device, wherein the sand-sliding device is arranged in the tower body; the ventilation device is arranged on a tower wall; a sand inlet is formed on the top of the tower body, and a sand outlet is formed at the bottom of the tower body; the sand-slidingdevice comprises a sand-sliding plate group which consists of a plurality of sand-sliding plates and a water cooling system; the sand-sliding plates are arranged on the inner wall of the tower body in a slant mode; the tops of the sand-sliding plates are fixedly connected with the inner wall of the tower body, the bottoms of the sand-sliding plates extend to a center line of the tower body downwards in a slant mode or extend out of the center line slightly; the water cooling system comprises a cooling pipeline, a cooling water inlet and a cooling water outlet; the cooling pipeline is fixedly arranged on the backs of the sand-sliding plates; the cooling water inlet and the cooling water outlet are formed on the outer wall of the tower body; and sand glides in an 'S' shape. The used sand flow state cooling dust removal device reduces energy consumption, and has a good cooling effect, and a simple structure.

Description

technical field [0001] The invention belongs to cooling and dedusting equipment in the field of casting, and in particular relates to an old sand fluid cooling and dedusting device. Background technique [0002] In the sand treatment process, whether it is clay sand, resin sand or V-method casting, the cooling and dust removal of old sand is very critical, and it is also a difficult point in the international sand treatment work. [0003] In recent years, the international sand treatment professional production plant has done a lot of work on the cooling and dust removal of used sand. Whether it is "double-disc cooling", "intelligent water spray cooling sand recovery device", and "drum cooler" and other cooling methods, there are problems such as poor cooling effect, high equipment investment, single function, and large equipment power loss. and other shortcomings. Contents of the invention [0004] In order to overcome the above-mentioned problems existing in the prior ...
