Quick-cooling casting sand storage cabinet

Abstract

The invention discloses a quick-cooling casting sand storage cabinet which is composed of a support, a sand outlet, a conical barrel, an inner barrel, an outer barrel, an ear hook, a heat pipe, buffer plates and a reinforcing rib plate, wherein the inner barrel is a circular barrel which is vertically arranged, and the lower part of the inner barrel is connected with the sand outlet through the conical barrel and welded on the support; the inside of the sand outlet is provided with a sand outlet device; the inner wall of the inner barrel is provided with the buffer plates; the position corresponding to the place on which each buffer plate is in contact with the barrel wall is provided with a hole into which the evaporation section of the heat pipe is inserted, and the buffer plates and the barrel wall are kept in good contact; and the condensation section of the heat pipe is in a pipe finned structure and positioned in the interlayer formed by the inner barrel and the outer barrel. The invention adopts the heat pipe cooling technique, thereby reducing the volume and occupied area of the sand processor; the interlayer structure of the inner barrel and the outer barrel strengthens the function of induced draught cooling, thereby realizing cooling at zero energy consumption without destroying the structure and components of the casting sand; the fan-shaped buffer plates relieve the pressure and impact of the sand on the sand outlet valve, enhances the operating performance of the equipment and prolongs the service life of the equipment.

Description

technical field [0001] The invention relates to casting sand processing equipment, in particular to a quick-cooling casting sand storage cabinet. Background technique [0002] Casting is a common metal forming technology, and it is also an important field that reflects a country's steel processing level. In the casting production line, after the casting sand is stripped from the casting blank, it needs to be crushed and cooled and sent back to the previous forming process. The cooling rate The height of the sand treatment process and the operation level of the equipment are restricted. Most of the current processes adopt comprehensive measures such as fluidized bed, ebullated bed, water spray cooling and storage cabinet cooling. Although the fluidized bed and ebullated bed have relatively high cooling rates, they are Pneumatic energy consumption is high, and the operation noise is large; water spray cooling operation is difficult, which has a great impact on the uniformity a...

[0002] Casting is a common metal forming technology, and it is also an important field that reflects a country's steel processing level. In the casting production line, after the casting sand is stripped from the casting blank, it needs to be crushed and cooled and sent back to the previous forming process. The cooling rate The height of the sand treatment process and the operation level of the equipment are restricted. Most of the current processes adopt comprehensive measures such as fluidized bed, ebullated bed, water spray cooling and storage cabinet cooling. Although the fluidized bed and ebullated bed have relatively high cooling rates, they are Pneumatic energy consumption is high, and the operation noise is large; water spray cooling operation is difficult, which has a great impact on the uniformity and water content of foundry sand; although storage cabinet cooling does not have the disadvantages of the above-mentioned methods, but the cooling efficiency is low and the time is long, making The sand treatment process has a large amount of sand stored, and the equipment volume and floor space are large
