Description

Molten iron filter device

Technical field

The utility model relates to a kind of coremaking equipment suitable for yin-yang rotor, and in particular to a kind of molten iron filter device.

Background technique

It generally will use ceramic filter in Foundry Production: for carrying out the slag in molten iron during casting and pouring Filter, reduction form cinder hole risk；Previous filtering does setting and is not provided with slag trap, dark air-out needle, when there are many slag in molten iron When, filtering base is easy to be plugged, and reduces the flow of molten iron, and it is serious to be easy to produce the problem of can not pouring (casting is scrapped), It is likely to cause filtering base pressure excessive, causes filter breakage in filtering base, cause casting to be scrapped into casting type chamber； Such as China Patent Publication No.: a kind of 207308890U funnel sprue cup disclosed in 2018, including sprue cup ontology, institute The sprue cup ontology stated is cylindrical, and one end of cylindrical body is casting ladle iron liquid socket end, and the other end is running gate system connection It holds, bottom of a cup is provided in cylindrical body, a through-hole being connected to running gate system sprue, through-hole are set in the bottom of a cup Two sides be respectively set one along casting ladle iron liquid socket end extend boss；The bottom of a cup is by the first bottom of a cup and the second bottom of a cup Constitute and connected by stage portion transition, the top surface of first bottom of a cup is higher than the top surface of the second bottom of a cup, the through-hole with The boss of its two sides is respectively positioned in the first bottom of a cup.When it is used when there are many slag in molten iron, filtering base is easy to be plugged, drop The low flow of molten iron, it is serious to be easy to produce the problem of can not pouring (casting is scrapped), it is likely to cause filtering base pressure It is excessive, filter breakage in filtering base is caused, causes casting to be scrapped into casting type chamber.

Utility model content

Utility model aims to solve the above-mentioned prior arts to exist when there are many slag in molten iron, and filtering base holds very much It is easily plugged, reduces the flow of molten iron, serious be easy to produce can not pour the problem of casting of initiation is scrapped, and provide a kind of tool The molten iron filter device for having exhaust, keeping away slag effect

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of molten iron filter device, feature exist In: including cross gate, upper filtering base, air-out needle, lower filtering base, ceramic tube ingate and filter, during the upper filtering base is in Empty square mesa-shaped, the side of the upper filtering base raises upward to form collection slags hollow and with upper filtering base connects with the internal cavities Packet, the cross gate are connect with the side wall of the upper filtering base other side, and the cavity inside the cross gate and the upper filtering base connects It is logical, air-out needle is fixed at the top of the slag trap, air-out needle upwardly extends, the sky inside the air-out needle and the slag trap Chamber connection, the upper filtering base correspond to that slag trap position is downwardly open, and the lower filtering base is in hollow inverted trapezoidal shape, under described The slag trap position of the corresponding upper filtering base of filtering base offers connector, and the lower filtering base bottom and ceramic tube ingate connect It connects, ceramic tube ingate is connected to the cavity inside lower filtering base, and the upper filtering base is connect with the top of the filter, institute The top for stating lower filtering base is connect with the lower part of the filter.Since slag is gently to be easy to float on molten iron surface very much, this reality Slag can be focused in the slag trap on top with novel, the gas in running gate system can also by air-out needle discharge type chamber, Reduce the risk of slag plug filter piece, so that reducing casting can not pour the risk scrapped, decreases filter breakage Risk ensure that the quality of casting.

Preferably, the filter includes filter mounting box and filter, the top of the filter mounting box is solid Surely it is connected to the lower section of the upper filtering base, the lower part of the filter mounting box is fixedly connected on the upper of the lower filtering base Side, the filter are mounted on the middle part of the filter mounting box.

Preferably, being equipped with several ceramic tube ingates on the lower filtering base.

Preferably, lower part of the outer rim of the lower filtering base top surface with the filter mounting box is fixed.

The substantial effect of the utility model is: the utility model can focus on slag in the slag trap on top, casting Gas in system can also reduce the risk of slag plug filter piece by air-out needle discharge type chamber, to reduce casting The risk scrapped can not be poured, the risk of filter breakage is decreased, ensure that the quality of casting.

Specific embodiment

Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically It is bright.

Embodiment 1:

A kind of molten iron filter device (referring to attached drawing 1 and attached drawing 2), including cross gate 3, upper filtering base 1, air-out needle 5, descended Filter block 2, ceramic tube ingate 6 and filter 7, the upper filtering base are in hollow square mesa-shaped, a side of the upper filtering base to On convex to form slag traps 4 hollow and with upper filtering base connects with the internal cavities, the cross gate and the upper filtering base other side Side wall connection, the cross gate are connected to the cavity inside the upper filtering base, are fixed with air-out needle at the top of the slag trap, Air-out needle upwardly extends, and the cavity connection inside the air-out needle and the slag trap, the upper filtering base corresponds to slag trap position Set downwardly open, the lower filtering base is in hollow inverted trapezoidal shape, the slag trap position of the corresponding upper filtering base of the lower filtering base Connector is offered, the lower filtering base bottom is connect with ceramic tube ingate, inside ceramic tube ingate and lower filtering base Cavity connection, the upper filtering base are connect with the top of the filter, top and the filter of the lower filtering base Lower part connection.Lower part of the outer rim of the lower filtering base top surface with the filter mounting box is fixed.The filter packet Filter mounting box and filter are included, the top of the filter mounting box is fixedly connected on the lower section of the upper filtering base, institute The lower part for stating filter mounting box is fixedly connected on the top of the lower filtering base, and the filter is mounted on the filter peace The middle part of mounted box.Several ceramic tube ingates are installed on the lower filtering base.

Since slag is gently to be easy to float on molten iron surface very much, the present embodiment can lodge the washing away scum collection of molten iron In to top slag trap in cavity at, the gas in running gate system can also reduce slag by air-out needle discharge type chamber The risk of plug filter piece decreases the risk of filter breakage so that reducing casting can not pour the risk scrapped, and guarantees The quality of casting.

Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
