Technical Field

The invention relates to a device for retaining aluminum liquid and a flow hole plugging method.

Background

For devices which are not tilted and used for storing aluminum liquid, such as an aluminum smelting furnace, a heat preservation furnace, a degassing box, a filtering box and the like, a flow hole for discharging the aluminum liquid is a position with high safety risk. Once the flow holes are not tightly locked, high-temperature molten aluminum is easy to flow out, and serious equipment and personnel safety accidents are caused. How to realize reliable, stable, simple and efficient locking of the flow hole is of great importance.

Medium and small aluminum casting enterprises are limited by cost and conditions, and generally adopt a mode of manually and directly driving a hole plugging drill rod into a hole plugging brick for plugging a hole, or using an aluminum ingot or an iron plate to abut against the hole after the hole plugging drill rod is firmly driven. The simple mode has great risk, is easy to loosen and run due to insufficient force, shortens the service life of the brick for the runner due to too large force, and brings great safety risk.

Disclosure of Invention

In view of the defects of the prior art, one of the purposes of the invention is to provide a device for retaining aluminum liquid to realize reliable plugging of a flow hole; the invention also aims to provide a flow hole plugging method for the device for retaining the aluminum liquid.

In order to solve the technical problems, the technical scheme of the invention is as follows:

a device for retaining aluminum liquid comprises

The body is provided with a cavity for retaining aluminum liquid and a flow hole communicated with the cavity; also comprises

One end of the drill rod is detachably inserted into the flowing hole, the other end of the drill rod extends out of the body, a compression bar perpendicular to the drill rod is arranged on a section of the drill rod extending out of the body, and two ends of the compression bar extend to two sides of the drill rod;

at least 2 mounting seats fixed on the outer wall of the body;

the rotating rod sequentially and rotatably penetrates through the at least 2 mounting seats;

the pressing arm is perpendicular to the rotating rod, one end of the pressing arm is fixed on the rotating rod, the other end of the pressing arm is provided with a pressing seat, and the pressing seat is provided with a first groove through which the drill rod can pass;

the screw rod is vertically fixed on the body;

the operating rod is parallel to the pressing arm, one end of the operating rod is fixed on the rotating rod, the other end of the operating rod is provided with a pressing plate, and a second groove for the screw rod to pass through is formed in the pressing plate; and

and the hand wheel is in threaded connection with the screw rod.

So, compress tightly first groove on the seat and can supply the drill rod to pass, second groove on the action bars can supply the lead screw to pass, and action bars, compression arm are parallel to each other and perpendicular with the rotary rod, form convertible structure from top to bottom, when control action bars overturn from top to bottom, and the compression arm follows the action bars and overturns from top to bottom. When the operating rod is turned downwards to a position where the screw rod penetrates through the second groove, the pressing arm is also turned downwards to a position where the drill rod penetrates through the first groove, and at the moment, due to the existence of the pressing rod, the pressing rod can limit the turning freedom degree of the pressing seat, so that when the pressing plate is further pressed inwards through the hand wheel, the rotating rod can further transmit torque to the pressing arm, the drill rod is further pressed, the freedom degree of outward movement of the drill rod is limited, and reliable plugging is realized; when the aluminum liquid in the device needs to be emptied, the hand wheel can be screwed out, the operating rod is turned upwards (for example, the operating rod is turned to the state that the pressing arm leans against the body arm), and then the aluminum liquid is discharged according to the conventional discharging flow.

Further, the mount pad includes the pedestal, is equipped with the ascending third groove of opening on the pedestal, the rotary rod movably passes the third groove. So, when need not the shutoff, can upwards take out rotary rod, the convertible structure that compresses tightly arm, action bars etc. formed can, avoid above-mentioned structure to cause adverse effect to the releasing.

Furthermore, the quantity of mount pad is 2, sets up in the top of flowing the eye, and distributes along the horizontal direction in proper order.

Further, the first slot opens downward.

Optionally, the compressing seat is hook-shaped.

Furthermore, 2 grid blocking pieces are arranged on the rotating rod, and the 2 grid blocking pieces are located between the 2 mounting seats. Therefore, the distance between each grid stopper and the mounting seat outside the grid stopper is reasonably regulated, so that the minimum distance between the grid stopper and the mounting seat is smaller than the minimum distance between the end of the rotary rod and the grid stopper, and the rotary rod can be effectively prevented from being separated along the length direction of the rotary rod.

Further, the operating rod is located on one side or right above the screw rod. Optionally, the second groove is located on one side of the screw rod, and the second groove is laterally opened; optionally, directly above the screw, with the second slot opening downwardly.

Furthermore, a stepped shaft sleeve for the second groove to pass through is fixed on the inner side of the hand wheel, and the shaft sleeve and the hand wheel share the central axis.

Further, the device is a non-tipping device.

Further, the device is one of an aluminum smelting furnace, a heat preservation furnace, a degassing box and a filter box.

Based on the same inventive concept, the invention also provides a flow hole blocking method of the device, which comprises the following steps:

s1, inserting one end of the drill rod into the flowing hole, and pre-tightening;

s2, rotating the pressing arm towards the direction of the flow hole, enabling the drill rod to penetrate through the first groove, enabling the screw rod to penetrate through the third groove, and enabling the pressing seat to abut against the pressing rod;

and S3, screwing the hand wheel into the screw rod until the pressing plate is pressed tightly, and realizing plugging.

Compared with the prior art, the invention has the following beneficial effects:

(1) the invention can easily and reliably plug the flow hole by adjusting the hand wheel, the operating rod and the like, keeps a locking state and avoids the risk of loosening.

(2) Compared with the traditional method for blocking the flow hole, the method for blocking the flow hole can easily and reliably block the flow hole without strong impact during hole blocking, and the flow hole brick can be free from being struck by external force, so that the service life is prolonged.
