The invention relates to a jacketed multi-loop
naphthalene forced
crystallization and recycling apparatus, comprising a
barrel, a multi-layer screen tube, a grid plate, a needle bearing, an O-shaped belt, a
pulley, and a reduction motor; the needle bearing is mounted at the bottom of the
barrel, a shaft lever of the grid plate is mounted in the needle bearing, the grid plate and the multi-layer screen tube are nested in a staggered manner to form a multi-loop structure; a fastening structure is provided between the bottom of the multi-layer screen tube and a bottom stand of the
barrel to fix the barrel and the multi-layer screen tube; the reduction motor drives the grid plate to rotate through the o-shaped belt; the grid plate is fitted with a
brush, the
brush comes in frictional contact with the surface of the multi-layer screen tube when the grid plate rotates to scrape off
crystal that falls into a tank. The jacketed multi-loop
naphthalene forced
crystallization and recycling apparatus as an auxiliary device to a
naphthalene tank
breather valve and is mounted between a naphthalene tank and the
breather valve through a reducing
flange to carry out naphthalene forced cooling and
crystallization and scrape off the
crystal into the tank; the jacketed multi-loop naphthalene forced crystallization and recycling apparatus is simple in structure and is easy to implement, and the problem of the prior art that naphthalene
crystal blocks the top
breather valve of a naphthalene
storage tank is solved.
