Description

Melting furnace feeder

Technical Field

The utility model belongs to the technical field of metal casting, especially, relate to a melting furnace charging means.

Background

Casting is a method in which liquid metal is cast into a casting cavity that conforms to the shape of a part, and after it is cooled and solidified, a part or a blank is obtained. The cast blank achieves the aim of no machining or less machining due to the fact that the cast blank is almost formed, so that the cost is reduced, the manufacturing time is reduced to a certain extent, and the method is one of the bases of modern equipment manufacturing industry. Before metal casting, a melting furnace is needed to change metal from a solid state to a liquid state, the liquid level of the molten metal is gradually lowered after the molten metal is taken, and new solid metal raw materials need to be added into the melting furnace in time. However, solid metal raw materials and the like are heavy, and easily fall into a melting furnace directly in the charging process, so that the metal liquid level in the melting furnace fluctuates, the molten metal is easy to overflow outwards, and the molten metal has high temperature, so that serious potential safety hazards are buried.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, a feeder of a melting furnace belongs to the technical field of metal casting, and can prevent metal liquid from overflowing from the melting furnace in the feeding process.

The utility model discloses a melting furnace charging means, including the fixed casing 1 of charging means, 1 inside link up from top to bottom of the fixed casing of charging means, the casing 1 inside that link up from top to bottom can regard as reinforced passageway. Be provided with first flitch 2 and second flitch 3 in the fixed casing 1 of charging means, first flitch 2 articulates on the inner wall of the fixed casing 1 of charging means, can make the relative pin joint of first flitch 2 rotate. The bottom of first flitch 2 articulates there is electric putter 4, and electric putter 4's the other end articulates on the inner wall of fixed casing 1, and electric putter 4 flexible can drive first flitch 2 and overturn from top to bottom to can empty the metal solid raw materials on first flitch 2 on second flitch 3. On the one end of second flitch 3 was fixed in the inner wall of the fixed casing 1 of charging means, second flitch 3 was used for buffering first flitch 2 and emptys the metal solid raw materials that get off, prevented that the metal solid from directly dropping the liquid splash that arouses in to the metal liquid. The other end of the second material plate 3 is arranged in a hanging manner, so that the metal fixing raw materials on the second material plate 3 can fall into the melting furnace through a feed opening formed between the second material plate 3 and the inner wall of the shell 1. And the second flitch 3 is located first flitch 2 board lower part, and crisscross setting with first flitch 2, and the second flitch 3 of crisscross setting can effectively block metal liquid's splash when metal solid raw materials drop with first flitch 2. The bottom of the second material plate 3 is fixed with a vibration motor 5, and under the action of the vibration motor 5, the metal solid raw materials can slide down from the second material plate 3 to the melting furnace.

The second material plate 3 is obliquely arranged downwards, and the second material plate 3 which is obliquely arranged downwards can improve the charging efficiency of the metal solid raw material.

The third material plate 6 is arranged at the lower part of the second material plate 3, the distance between the metal solid raw material and the metal liquid in the melting furnace is further shortened by the third material plate 6, the fluctuation of the metal liquid level caused by the falling metal solid is smaller, and the buffer effect is achieved. The third material plate 6 is hinged to the inner wall of the feeder fixing shell 1 and is arranged in a staggered mode with the second material plate 3, so that the third material plate 6 can be pressed down when metal solids fall, and the metal solid raw materials can fall into the melting furnace conveniently. The top of the third material plate 6 is fixed with an expansion spring 7, the other end of the expansion spring 7 is fixed on the inner wall of the feeder fixing shell 1, and the expansion spring 7 can enable the third material plate 6 to automatically reset after the metal solid raw material falls into the melting furnace.

The following describes the usage of the present invention with reference to the drawings.

The method comprises the following steps: the feeder is vertically fixed at the top of a furnace mouth of a melting furnace;

step two: the electric push rod 4 is extended out to enable the first material plate 2 to be in a horizontal position;

step three: adding a metal solid raw material into a feeder shell 1, and stacking the raw material on a first material plate 2;

step four: retracting the electric push rod 4 to drive the first material plate 2 to overturn, so that the metal solid raw material on the first material plate 2 slides to the second material plate 3;

step five: the electric push rod 4 is extended out to reset the first material plate 2, and the vibration motor 5 is started to slide the metal solid raw materials on the second material plate 3 into the melting furnace.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
