Sand drying device with anti-return sand kiln head

Abstract

The invention relates to the mechanical field of a sand drier, in particular to a sand drying device with an anti-return sand kiln head. The sand drying device comprises a sand drier unit, a kiln headand a combustion furnace; the sand drier unit comprises a sand drier shell, a sand drier inner cylinder is arranged in the sand drier shell, and an inlet sealing plate is connected to the port of theouter shell of the sand drier and the port of the inner cylinder of the sand drier; the kiln head comprises a kiln head cylinder with one end connected to the inlet sealing plate, an annular kiln head sealing plate is arranged on the inner wall close to the other end of the kiln head cylinder, and the inner diameter of the kiln head sealing plate is connected with a sand collecting cone; the combustion furnace is correspondingly arranged at the sand collecting cone, the top of the combustion furnace is provided with a sand flowing groove communicated with the sand collecting cone, a furnace head sealing ring is arranged at the port of the combustion furnace, and a furnace head cone is arranged at the port of the combustion furnace; and a fish scale sheet is arranged on the outer wall of the port of the kiln head cylinder close to the combustion furnace, one end of the fish scale sheet is fixed on the kiln head cylinder through a fixing ring, and the other end of the fish scale sheet is in contact with the furnace head cone. Through the changed kiln head, the drying effect is good, the sand flow is smooth, and sand returning is avoided.

Description

technical field [0001] The invention relates to the mechanical field of sand drying machines, in particular to a sand drying device with an anti-sand return kiln head. Background technique [0002] In the industrial field, sand drying machines are often used machinery. Sand drying machines are widely used in the drying of materials such as sand and mortar. In order to minimize the damage to the environment caused by the on-site cement mixing For the implementation of the optimal ratio of cement, the country has promoted the construction of construction dry powder ready-mixed mortar stations with good environmental protection effects in recent years. The dry powder ready-mixed mortar station needs to use a wet sand dryer. However, many traditional sand drying equipment have simple structures and simple working principles. The phenomenon of dryer blockage and sand return often occurs, especially when the humidity of the sand increases. , in order to achieve the effect of no s...

Problems solved by technology

The dry powder ready-mixed mortar station needs to use a wet sand dryer. However, many traditional sand drying equipment have simple structures and simple working principles. The phenomenon of dryer blockage and sand return often occurs, especially when the humidity of the sand increases. , in order to achieve the effect of no sand return, when the humidity of the wet sand increases, the traditional sand oven reduces the sand flow rate in the process tank, reduces the length of the sand flow in the kiln head tube, and makes up for the lack of forward driving force of the quicksand , this method is obviously at the cost of reducing output, which is unreasonable. At the same time, when many traditional sand drying components and furnace fire components fail to seal, there is no structure that can slow down the convection velocity.
