Abstract
The utility model discloses a novel sand cooling device, including the sand fill of depositing of bottom, at the top installation heat exchange unit who deposits the sand fill, heat exchange unit with deposit through sand gate valve interval between the sand fill, install temperature sensor and one row of die cavity that communicates in proper order in heat exchange unit, the water inlet on die cavity one end and the heat exchange unit that communicate together communicates with each other, the delivery port on the other end and the heat exchange unit communicates with each other, the sand gate valve is connected with temperature sensor and is in normally closed state, detect in the heat exchange unit temperature at temperature sensor and drop to the setting value after open, install rather than communicating sand receiving fill at the top of heat exchange unit. The utility model discloses a novel sand cooling device, through the die cavity increase in the heat exchange unit with the heat exchange area of molding sand, take away the heat in the molding sand through incessant cooling water in the die cavity, carry out rapid cooling to the molding sand to carry out the cyclic utilization of molding sand in order fast.
Description
Technical Field
The utility model relates to a V method casting production facility field, specific novel sand cooling in this field that says so relates to.
Background
In a V-method casting production line, the overheating of used sand has a plurality of adverse effects on casting, and after the sand pouring and shakeout are completed, the used sand is collected and recycled through sand treatment. The cooling time of the V-method casting in the casting mould is longer than that of other sand moulds, the average temperature of used sand is high, and the cooling difficulty of the used sand is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a novel molding sand rapid cooling device is provided.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a novel sand cooling device, its improvement lies in: the sand storage device comprises a sand storage hopper at the bottom, a heat exchange unit is installed at the top of the sand storage hopper, the heat exchange unit and the sand storage hopper are separated through a sand gate valve, a temperature sensor and a row of cavities which are sequentially communicated are installed in the heat exchange unit, one end of each cavity communicated with the water inlet of the heat exchange unit is communicated, the other end of each cavity is communicated with a water outlet of the heat exchange unit, the sand gate valve is connected with the temperature sensor and is in a normally closed state, the sand gate valve is opened after the temperature sensor detects that the temperature in the heat exchange unit is reduced to a set value, and the sand receiving hopper communicated with the.
Further, the temperature sensor is a platinum resistance temperature sensor.
Furthermore, the water inlet is positioned at the lower end of the side wall of the heat exchange unit, and the water outlet is positioned at the upper end of the side wall of the heat exchange unit.
The utility model has the advantages that:
the utility model discloses a novel sand cooling device, through the die cavity increase in the heat exchange unit with the heat exchange area of molding sand, take away the heat in the molding sand through incessant cooling water in the die cavity, carry out rapid cooling to the molding sand to carry out the cyclic utilization of molding sand in order fast.

fig. 2 is a structural schematic diagram of the novel sand cooling device disclosed in embodiment 1 of the present invention as seen from the right.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the present embodiment, the temperature sensor is a platinum resistance temperature sensor. The water inlet is positioned at the lower end of the side wall of the heat exchange unit, and the water outlet is positioned at the upper end of the side wall of the heat exchange unit.
The discharged hot molding sand of last process enters into heat exchange unit through connecing the sand hopper (connect the sand hopper can avoid the hot molding sand to cause wearing and tearing to it when directly getting into heat exchange unit), and the sand gate valve is in the closed condition this moment, and hot molding sand can fully contact with the die cavity surface. The cooling water is continuous flows through the die cavity through the water inlet, takes away the back with the heat in the molding sand and discharges from the delivery port to carry out rapid cooling to the molding sand, give the sand gate valve signal after platinum resistance temperature sensor detects the molding sand temperature in the heat exchange unit and drops to setting for the required value, in the sand gate valve opens the molding sand that makes after the cooling falls into and deposits the sand hopper, in order to treat that the subsequent handling uses. And after the shakeout is finished, the sand gate valve is closed, the cooling device receives new hot molding sand again and repeats the process, and the cooling device carries out the cooling of the hot molding sand in a rapid and orderly manner.
Claims (3)
1. The utility model provides a novel sand cooling device which characterized in that: the sand storage device comprises a sand storage hopper at the bottom, a heat exchange unit is installed at the top of the sand storage hopper, the heat exchange unit and the sand storage hopper are separated through a sand gate valve, a temperature sensor and a row of cavities which are sequentially communicated are installed in the heat exchange unit, one end of each cavity communicated with the water inlet of the heat exchange unit is communicated, the other end of each cavity is communicated with a water outlet of the heat exchange unit, the sand gate valve is connected with the temperature sensor and is in a normally closed state, the sand gate valve is opened after the temperature sensor detects that the temperature in the heat exchange unit is reduced to a set value, and the sand receiving hopper communicated with the.
