Example Embodiment

[0011] In order to further understand the content, features, and effects of the present invention, the following examples are given to illustrate in detail as follows:

[0012] See figure 1 The present invention includes a cylinder 6 with an exhaust flue 2 at the top and a tapered bottom 11 at the bottom, and a sand outlet 10 is provided at the center of the bottom of the tapered bottom 11.

[0013] On the top of the inner cavity of the cylinder 6 is provided a first sand separating cone 3, below the first sand separating cone 3 is provided a sand disperser 4 to further disperse the waste foundry sand, and on the top wall of the cylinder 6 There is waste sand inlet pipe 1 whose bottom end is directly opposite to the top of the first sand separating cone 3. The waste foundry sand enters the inner cavity of the cylinder 6 through the waste sand inlet pipe 1, falls on the top of the first sand cone 3, and then spreads through the cone surface. The sand disperser 4 is used to further...

Abstract

The invention relates to an energy-saving type flowing roasting furnace for regenerating casting waste sand. The energy-saving type flowing roasting furnace comprises a barrel which is provided with a draught flue on the top and a cone bottom at the bottom, wherein the center of the bottom of the cone bottom is provided with a sand outlet; the top of an inner cavity of the barrel is provided with a first sand separating cone; a sand dispersing device for further dispersing the casting waste sand is arranged under the first sand separating cone; the top wall of the barrel is provided with a waste sand inlet pipe, and the bottom end of the barrel just faces to the cone top of the first sand separating cone; a heat preserving layer covers the outer wall of the barrel; a plurality of burners are arranged in the middle of the side wall of the barrel; a heat exchanger is arranged at the bottom of the inner cavity of the barrel and above the cone bottom and comprises a flat cylindrical shell, and the outer wall of the shell is fixedly connected with the inner wall of the barrel; a plurality of vertical tubes which are through along the longitudinal direction are fixedly connected between the top wall and the bottom wall of the shell; a plurality of vertical air pipes are arranged on the top wall of the shell and among the vertical tubes; inner cavities of the air pipes are communicated with the inner cavity of the shell; the outer wall of the shell is also provided with an air inlet.

Description

technical field [0001] The invention belongs to the technical field of roasting furnace equipment, and in particular relates to an energy-saving fluid roasting furnace used for regeneration of foundry waste sand. Background technique [0002] In modern casting technology, coated sand and resin sand are usually used as the base material for molding. After the casting of the workpiece is completed, the above-mentioned coated sand and resin sand become foundry waste sand. Due to the immaturity of waste sand treatment process and the lag of environmental protection concept, there was no reasonable foundry waste sand treatment process and equipment in the early stage. Considering that the regeneration and recycling of foundry waste sand has great economic value and environmental protection value, coupled with the advantages of low thermal expansion rate of reclaimed sand, which can improve the quality and yield of castings, the treatment process and equipment of foundry waste san...
