Description

Technical Field

Heating and insulation tanks have the advantages of energy saving, corrosion resistance, strong production capacity and easy cleaning. They are widely used in the dairy industry, food, pharmaceutical, chemical, beverage and other industrial sectors. When the heating and insulation tank is heated by steam, the high-temperature steam will generate strong vibration when entering the relatively low temperature heating and insulation tank. Therefore, a silencer is required to silence the heating and insulation tank.

[0003] After searching, the authorization announcement number CN209326406U discloses a water tank steam heating silencer, including a connecting flange, a guide pipe, a cover plate, a silencer pipe and a silencer chamber, the silencer pipe is embedded in the silencer chamber, the lower end surface is connected to the bottom of the silencer chamber, the upper end surface is connected to the guide pipe through the connecting flange, the side walls of the silencer pipe and the silencer chamber are evenly distributed with a plurality of through holes, the outer surface of the silencer pipe and the inner surface of the silencer chamber are evenly distributed with a plurality of partitions, the cover plate is embedded in the upper end surface of the silencer chamber, coaxially distributed with the silencer chamber and slidably connected to the inner surface of the silencer chamber, and an axial hole is provided on the cover plate, and is covered on the outer side of the guide pipe through the axial hole.
