ES2277527A1 - Ladle for transporting molten metal, has discharge opening provided in side of sloping discharge tube that acts as pivot axis for ladle relative to its support structure - Google Patents

Abstract

Device for transporting molten metal comprises a ladle which is mounted in a support structure and includes an upper inlet opening for receiving the metal, as well as a discharge opening located to one side of the inlet opening, in the side of a sloping discharge tube. This tube can rotate relative to the support structure so that it acts as the pivot axis for the ladle relative to this structure. The ladle has a folding lid for covering the inlet opening and the discharge tube includes a lid for sealing its bottom end.

Description

Metal transport device molten.

Object of the invention

The present invention relates to a device for transporting molten metal, of which comprise a spoon intended to contain and transport the laundry or molten metal for pouring through the upper mouth and that are arranged on a frame for tilting during the emptying or unloading operation.

Background of the invention

Currently for metal transport various types of spoons or containers are used specially adapted for this service. These spoons can be hung on cranes that transport them, or in the case of need more mobility and a reduced size, the spoons are arranged on racks or structures that can be transported by conventional forklifts. For this, these racks or support structures have inferiorly some housings or passages for the grip of the device using forklift fingernails.

These devices present various problems among which the risk of involuntary discharge of a part of the laundry when performing sudden maneuvers during transport and lack of control in the pouring of metal when dump the spoon for unloading, leaving the metal through the mouth upper irregularly depending on the tilting angle of the spoon.

Other drawbacks of these devices is that the spoon before being used must be subjected to a preheating to prevent cooling of molten metal to transport and that said spoon must have an insulation Suitable to reduce heat transfer and loss.

Description of the invention

The device for transporting metal Cast of this invention has some peculiarities construction that allow safe transport of molten metal, no risk of accidental spillage and greater control of spillage of said metal when the spoon is emptied.

The device comprises a spoon that it presents laterally and next to its upper mouth a mouth of discharge attached to the side mouth of a discharge tube, which It has a certain lateral inclination and is mounted with possibility of rotation with respect to the support structure or frame, said discharge tube defining the tilt axis of the spoon with respect to the support structure.

In this way when the spoon is tilted, the spill or exit of the molten metal is done through the lateral mouth of said tube, in a more controlled way, since the mouth is arranged in a fixed position with respect to the support structure and the pipe spout  It acts as a capacity, limiting and regulating the metal output molten.

The spoon comprises a folding lid for the Close your upper mouth and avoid involuntary spills of the molten metal due to possible abrupt maneuvers during transport of the device with forklift or any other  conveyance.

It is also planned that the spoon is of a Ceramic insulating material and high strength. This allows it is not necessary to preheat the spoon before of pouring molten metal inside and preventing the loss of heat to the outside that entails a solidification of the metal in its inside, if it is for a long time, or at least its densification

The discharge tube has the upper end closed and has at the lower end, a mouth for the exit of the laundry, provided with a closing lid to prevent accidental pouring of the laundry during transport. This lid collaborates with the folding lid of the spoon in preventing accidental outflow of molten metal to the outside. This discharge tube cover is related to a hydraulic actuating cylinder for its control in
tancia

The discharge tube is fixed on the support structure by detachable clamps, which they allow the release, with respect to the support structure, of the set formed by the spoon and the tube Download

The device comprises at least two cylinders hydraulic for the tilt bucket drive to the support structure. In this way the failure of one of these cylinders does not involve the immediate fall of the bucket in the case if the molten metal is being poured through the pipe discharge.

The device comprises hydraulic connections of all hydraulic elements with the transport truck for its operation from its controls.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a perspective view of the device of the invention showing the spoon lid open

- Figure 2 shows an elevation view of the device.

- Figure 3 shows a plan view of the device.

- Figure 4 shows a profile view of the device.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the device for the transport of molten metal comprises a spoon (1), of ceramic material, intended for contain and transport the casting or molten metal and which has an upper loading mouth (11) and laterally, close to said upper mouth (11), a discharge mouth (12) fixed to the mouth side of a discharge tube (14) having a certain lateral inclination

The set formed by the spoon (1) and the tube discharge (14) is mounted with possibility of rotation with respect to a support structure (2), the axis being defined of rotation by the discharge tube itself (14).

The spoon (1) comprises a hinged lid (15) for closing the upper loading mouth (11). The tube of discharge (14) has its upper end closed and at its end lower one outlet or discharge of the laundry; is mouth bottom is provided with a closing cover (16) to prevent the accidental pouring of laundry during transport.

Said closure cap (16) of the tube (14) is found related to a hydraulic cylinder (17) of drive for closing and opening.

The support structure (2) presents inferiorly some housings (21) or passages for the grip of the device using a forklift or similar, presenting detachable clamps at the top (22) for securing the discharge pipe (14). The extraction of clamps (22) allows the release, with respect to the structure of support (2), of the assembly formed by the spoon (1) and the tube discharge (14), which greatly simplifies the operation of Spoon replacement.

The structure (2) comprises at least two hydraulic cylinders (23) for the tilting drive of the spoon (1) with respect to the support structure (2). By depressing the bucket (1), together with the discharge tube (14), towards a horizontal discharge position, molten metal passes through the mouth side (12) into the discharge tube (14) that is maintains the same inclination when forming the axis of rotation or tilt of the set, leaving molten metal evenly through the lower mouth of said discharge tube.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
