Sand temperature adjusting device

Abstract

The invention discloses a sand temperature adjusting device. The sand temperature adjusting device comprises a plurality of cooling water pipes which are fixed to a support. The upper part of each cooling water pipe is fixedly covered with a metal baffle piece in the extending direction of the cooling water pipe. The metal baffle pieces are bent towards the cooling water pipes. The horizontal width of each metal baffle piece is larger than the diameter of the corresponding cooling water pipe. Due to the fact that sand falls off from the upper parts of the cooling water pipes in a raining manner, and the upper parts of the cooling water pipes are covered with the metal baffle pieces, the sand can be prevented from directly impacting the cooling water pipes, and the sand impacts the metal baffle pieces; due to the good heat conductivity of the metal baffle pieces, the temperature transmission can be achieved, the falling sand is prevented from impacting the cooling water pipes, and abrasion and fractures of the cooling water pipes are avoided; and due to the fact that the metal baffle pieces are bent towards the cooling water pipes, the effect of uniformizing the falling sand can beachieved.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a sand temperature adjusting device. Background technique [0002] The sand temperature adjustment device is a cooling device for lost foam sand treatment, which cools the hot regenerated sand to a certain temperature to ensure that the sand temperature at the sand outlet meets the requirements for use. The sand temperature adjustment device mainly includes a material level detection device, a sand storage unit, a cooling unit, a drop It consists of a sand device, a bracket, etc. The cooling unit is evenly interlaced and densely distributed with cooling water pipes. The sand is rained down from the top of the cooling unit, and passes through several cooling water pipes in turn to achieve the purpose of cooling. However, at present, the sand is directly impacted and cooled during the falling process. Water pipes can easily lead to rupture of cooling water pipes, increasi...

[0002] The sand temperature adjustment device is a cooling device for lost foam sand treatment, which cools the hot reclaimed sand to a certain temperature to ensure that the sand temperature at the sand outlet meets the requirements for use. The sand temperature adjustment device mainly includes a material level detection device, a sand storage unit, a cooling unit, and a falling The cooling unit is composed of sand device, support, etc., and the cooling water pipes are evenly staggered and densely distributed in the cooling unit. The sand falls from the top of the cooling unit in the way of rain, and passes through several cooling water pipes in turn to achieve the purpose of cooling. However, the sand is directly impacted and cooled during the falling process. Water pipes can easily cause cooling water pipes to break, increasing maintenance time and costs
