FIG. 1 is an overall top view of the present invention;
fig. 2 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, an online tin liquid purification temperature control device comprises a tin bath 1, and a tin liquid 3 is arranged in the tin bath 1. The molten tin bath 1 comprises a molten tin bath bottom brick 1a, two ends of the molten tin bath bottom brick 1a are respectively provided with a wall brick 1e which is vertically distributed, and the horizontal height of the wall brick 1e is greater than that of the molten tin bath bottom brick 1 a.
Each wall brick 1e is provided with a groove wall brick 1b, and a top cover 1c is also erected between the groove wall bricks 1b at two sides. The tin bath 1 is divided into a wide section a and a narrow section b along the axial direction, and a transition section c is arranged between the wide section a and the narrow section b. The outer wall of the tin bath 1 is also wrapped with a tin bath steel shell 1 d. The structure of the tin bath 1 is the prior art, and the whole structure is not described in detail here.
Two sides of the transition section c of the tin bath 1 are respectively provided with a cavity 2, and the two cavities 2 are symmetrical to each other. The cavity 2 comprises a bottom brick 2a with one end connected with the outer wall of a wall brick 1e at the lower part of the tin bath 1, the upper surface of the bottom brick 2a and the bottom brick 1a of the tin bath are on the same horizontal plane, a pool wall brick 2b which is vertically distributed is arranged at the other end of the bottom brick 2a, and the horizontal height of the pool wall brick 2b is greater than the height of the bottom brick 2 a.
Be equipped with breastwall brick 2f in pool wall brick 2b upper end, be equipped with crown brick 2c on breastwall brick 2f, crown brick 2c one end link together with molten tin bath 1's top cap to form one and molten tin bath 1 outside and totally cut apart and sealed good independent space. The outer walls of the bottom bricks 2a, the breast wall bricks 2f, the pool wall bricks 2b and the top bricks 2c are also wrapped with steel shells 8, and one end of each steel shell 8 is welded with the tin bath steel shell 1 d.
The groove wall brick 1b is provided with a through hole 3a and a through groove 3b which are communicated with the cavity 2, the whole through hole 3a is positioned below the liquid level of the molten tin 3, and only the groove bottom of the through groove 3b is positioned below the liquid level of the molten tin 3. Therefore, the substances floating on the molten tin 3 can move between the cavity 2 and the molten tin bath 1 through the through grooves 3b, and the substances floating on the molten tin 3 can be blocked by the through holes 3a, so that the substances are prevented from moving between the cavity 2 and the molten tin bath 1.
A certain distance is arranged between the through hole 3a and the through groove 3 b. Therefore, the molten tin 3 in the molten tin bath 1 can flow into the cavity 2 through the through holes 3a or the through grooves 3b, the liquid level of the molten tin 3 flowing in through the through holes 3a is blocked by the bath wall bricks 1b, and the liquid level of the molten tin flowing in through the through grooves 3b can also flow in together. The liquid level of the tin liquid flowing into the cavity and the liquid level of the tin liquid in the tin groove are kept on the same horizontal plane.
The cavity 2 corresponding to the through hole 3a and the through groove 3b is internally provided with a linear motor 4 respectively, one end of the linear motor 4 is provided with a mounting seat, the mounting seat is mounted on the pool wall brick 2b, a heat insulation layer is covered outside the linear motor 4, a cooling water pipe is arranged between the heat insulation layer and the linear motor 4, and the cooling water pipe extends out of the pool wall brick 2b and is communicated with a cooling water source.
And the cable of the linear motor 4 also extends out of the pool wall brick 2b to be connected with a power supply. The flow direction of the molten tin 3 flowing into the cavity 2 is controlled by the linear motor 4, so that the molten tin 3 in the molten tin bath 1 and the cavity 2 can enter and exit the cavity 2 through the through holes 3a and the through grooves 3 b.
