Abstract

PURPOSE:To discharge the remained molten metal within a short time and to efficiently reuse the molten metal by supporting a position near a molten metal discharging hole in a filter vessel for molten metal with a side pivot shaft, providing vertical moving mechanism in the vicinity of a molten metal charging hole, thereby making the filter vessel tiltable. CONSTITUTION:The molten metal is charged from the molten metal charging hole 3 in the filter vessel 1, filled up in the filter vessel 2, heated by a heater 14, filtered by a side ceramic tube 11 and discharged from the tapping hole 4 through an opening hole 12. Then the side pivot shaft 15 in the right and left direction is provided in the lower surface near the molten metal discharging hole 4 to pivotally attach the filter vessel 1, and the vertical moving mechanism 16 is provided in the vicinity of the molten metal charging hole 3 to form so that the filter vessel is tilted. By this method, at the time of filtering a different metallic material after completing the filtering work, the filter vessel 1 is tilted by lifting the molten metal charging hole 3 side by the vertical moving mechanism 16 to discharge the remained molten metal from the tapping hole 4, thus the molten metal is wholly discharged within a short time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined tap water type filter tank.

[0002]

2. Description of the Related Art Conventionally, in a filtration tank having a filtration unit housed in a filtration chamber having a molten metal inlet and outlet, a drain port is provided at the bottom of the filter port, and the drain port is opened to discharge the residual hot water. The filtration tank adapted to do so is well known.

[0003]

In the known filter tank, when trying to melt a metal of a different kind from the metal that has been melted in the filter tank, the residual hot water and the new molten metal do not mix. As described above, the drain port was opened to drain the residual hot water (see the black arrow), but this method had the following problems. The first is that draining takes a considerable amount of time.
Due to the structure, the drain port cannot be formed at an extremely low position, and therefore the gradient to the drain port becomes gentle, so that the drain takes time. The second problem is that it is not easy to reuse the drained molten metal. The drain port is
Since it is not a tap, it is necessary to return the tapped water from the drain to the tap. However, handling the molten metal at high temperature is troublesome, and this work cannot be done easily.

[0004]

Therefore, according to the present invention, there is provided a filtration tank 1 in which a filtration unit 8 is housed in a furnace chamber 2 having a molten metal inlet 3 and an outlet 4.
The position near the tap hole 4 is fixed by a lateral pivot shaft 15,
An inclined tap water type filter tank provided with a vertical movement mechanism 16 on the opposite side of the shaft stopper.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 is an entire filtration tank for filtering molten metal (molten metal) such as aluminum, 2 is a filtration chamber formed in the filtration tank 3, 3 is a inlet of the filtration chamber 2, 4 is a tap of the filtration chamber 2, 5 Is a bottom wall of the filtration chamber 2, and 6 is a drain port of the filtration chamber 2. Drain port 6
A stopper 7 is attached to this. A filtration unit 8 is housed in the filtration chamber 2. The filtration unit 8 includes a front end plate 9 and a rear end plate 10 formed of a silicon carbide refractory plate (front and rear, right and left are used for convenience of description, and therefore may be represented in reverse). It has a structure in which a porous transverse ceramic tube 11 formed of an alumina porous tube in the front-rear direction is provided between the two. The horizontal ceramic tube 11 is provided in several rows above and below and in multiple rows on the left and right,
The front end plate 9 side is closed, the rear end plate 10 side is opened 12, and the molten metal is filtered by the horizontal ceramic tube 11 and then purified from the opening 12 to discharge the molten metal. Reference numeral 13 is a lid member of the filtration tank 1, and 14 is a heater attached to the lower surface of the lid member 13.

On the lower surface near the tap hole 4,
A horizontal pivot 15 in the left-right direction is provided, and the filtration tank 1 is pivotally attached by the horizontal pivot 15, and a vertical movement mechanism 16 is provided in the vicinity of the hot water inlet 3 on the opposite side of the horizontal pivot 15 to move the filtration tank 1 It is formed so as to be inclined. Reference numeral 17 is a vertical screw rod attached to the filtration tank 1 side, 18 is a floor, 19 is an opposite vertical screw rod attached to the floor 18 side, and 20 is both a lower portion of the vertical screw rod 17 and an upper portion of the opposite vertical screw rod 19. A rotary screw cylinder (so-called turnbuckle mechanism) that is screwed into the rotary screw cylinder 21, a driven gear fixed to the rotary screw cylinder 20, a drive gear 22 meshing with the gear 21, and a motor 23. The above structure is an example of a mechanism that lifts the hot water inlet 3 side and inclines the hot water outlet 4 as the center.

[0007]

[Operation] Next, the operation will be described. When a metal melt in which aluminum or the like is melted is poured through the inlet 3, it flows in the order of white arrows, fills the filtration chamber 2 from the inlet 3 through the communication port, and in the filtration chamber 2, the lid member 13 It is heated so as not to cool by a heater 14 attached to, is filtered by a horizontal ceramic tube 11, passes through an opening 12, and is tapped from a tap 4. When it is desired to filter a different metal material after the work is completed, usually, the plug 7 of the drain port 6 is removed and the residual molten metal is caused to flow in the direction of the black arrow for draining. However, there is a problem that it takes a long time and that it is not easy to reuse the one drained from the drain port 6.

In the present invention, the motor 23 is energized, the rotary screw cylinder 20 is rotated through the drive gear 22 and the driven gear 21, and the turnbuckle mechanism raises the inlet 3 side to incline the filtration tank 1. The hot water is discharged from the hot water outlet 4. Therefore, all the remaining molten metal can be taken out in a short time. Also, filter tank 1
Since it rotates around the tap hole 4, all the remaining molten metal taken out can be reused easily without waste.

EFFECTS OF THE INVENTION Conventionally, in a filter tank in which a filter unit is housed in a filter chamber having a molten metal inlet and outlet, a filter tank having a drain port at the bottom is well known. Well-known filter tank, when trying to melt and filter a metal that is different from the metal that had been melted up to that point, the plug of the drain port was removed and the residual molten metal was drained, but when using this method,
There are problems that it takes a considerable amount of time for draining and that the drained molten metal cannot be reused easily. However, according to the present invention, in the filtration tank 1 in which the filtration unit 8 is housed in the furnace chamber 2 having the molten metal inlet port 3 and the molten metal outlet port 4, the horizontal position of the filter tank 1 in the vicinity of the outlet port 4 is referred to as a horizontal axis. Since it is an inclined tap water type filtration tank in which the shaft is stopped by 15 and the vertical movement mechanism 16 is provided on the side opposite to the shaft stop portion, the hot water inlet 3 side is raised and the filtration tank 1 is tilted to discharge hot water. Not only can all the remaining molten metal be taken out in a short time, but since the filtration tank 1 is tilted around the tap hole 4 and all is tapped from the tap hole 4, it can be reused as it is without waste.
