Problems solved by technology

[0002] In the recycling of coated sand, it is common to use a high-temperature roasting structure for recycling; in the existing technology, the entire recycling system is too simple, and the recycling quality and efficiency need to be improved; especially the entire recycling process involves heating and cooling processes. The structural design of the existing technology in the heating and cooling process is unreasonable, resulting in energy waste and increasing recycling costs

Abstract

The invention discloses a precoated sand recycling system which comprises an upright suspension combustion hearth and a horizontal type boiling bed, wherein the bottom of the horizontal type boiling bed is partitioned by lower partitioning plates so as to form a plurality of uniform bottom air distribution cabins; a hot air hole is formed in each bottom air distribution cabin; a fume exhaust hole for exhausting fume is formed in the horizontal type boiling bed; the fume exhaust hole in the horizontal type boiling bed is communicated with a fume exhaust pipeline through a flue; a draft fan is arranged at an end part of the fume exhaust pipeline; a dividing wall cooler is arranged below the air distribution cabins of the horizontal type boiling bed; the top end of the dividing wall cooler is connected with the horizontal type boiling bed through a sand falling tube; an air outlet is formed in the upper part of the dividing wall cooler; a sand outlet and an air inlet are formed in the bottom of the dividing wall cooler; the air outlet is connected with an air preheater through a first hot air tube; the inlet of the air preheater is communicated with the first hot air tube; the outlet of a gas conveying pipeline is communicated with hot air holes of the air distribution cabins through a second hot air tube.

Description

technical field [0001] The invention relates to a film-coated sand recycling system, which is specifically used for recycling the film-coated sand. Background technique [0002] In the recycling of coated sand, it is common to use a high-temperature roasting structure for recycling; in the existing technology, the entire recycling system is too simple, and the recycling quality and efficiency need to be improved; especially the entire recycling process involves heating and cooling processes. The unreasonable structural design in the heating and cooling process of the prior art causes waste of energy and increases recovery costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coated sand recycling system for the deficiencies in the above-mentioned prior art, which can realize the recycling and reuse of coated sand with high efficiency and energy saving, and is helpful for continuous production and automatic pro...
