ある。As is known from the prior art, a heater group is buried on the lower surface side of a lid of a filtration chamber, and the molten metal in the filtration chamber is heated from the upper surface by the heater. In addition, there is a problem that thermal efficiency is poor. In addition, a heater group is buried in the wall around the periphery of the filtration chamber, which is separately known,
Heating the molten metal by a group of heaters in the wall not only complicates the production of the wall around the filtration chamber, but also has a problem of poor thermal efficiency. However, according to the present invention, the front wall 24
, Rear wall 25, right wall 26, left wall 27, bottom wall 18, and lid 11
Hot water at the upper part of the right wall of the square filtration chamber 2 surrounded by
The mouth 3 is formed, and between the front wall 24 and the rear wall 25
Multiple ceramic tubes for filtering molten metal extending in the front-back direction
A filter unit 4 having a filter 7 is provided, and
Is above the left and right heaters 13 and 12 that hang down in the filtration chamber 2.
With the ends 15 and 14 attached, the heater 1
The lower ends 17 and 16 of the heaters 13 and 12
The lower portions 17A and 16A are
Hanging down to a position near the bottom wall 18 so as to face the side position
The right heater 12 has the hot water inlet 3 formed therein.
Arrange a plurality of them inside the right wall 26 in the front-rear direction,
The left heater 13 is provided on the left wall 27 facing the right wall 26.
The right heater 1
2 between the lower part 16A and the filtration unit 4
Is provided with a right heat shield plate 19, and the lower portion of the left heater 13 is provided.
Between the minute 17A and the filtration unit 4
Since it is obtained by a filtration device provided with, as described above, the heater 12 and 13, the molten metal for filtering indoor exposure Chu suspended structure can be heated up and down uniformly, and the heat efficiency is good, the cost a simple structure It can be cheap, preheating before filtration work
In this case, the ceramic tubes 7 close to the heaters 12 and 13 can also be heated by the heat shield plates 19 and 20 without uneven heating, which has an effect of preventing the ceramic tubes 7 from being damaged.
