Abstract

A furnace car 1 has two sets of wheels where one pair of axles (13.1, 13.2) is at right angles to the other pair of axes (19.1, 19.2), so that the car can be moved in two different directions on perpendicular tracks. The car may travel through the furnace and then travel at right angles onto another track which is parallel to the furnace, so that the car can be returned to the starting point. The two sets of wheels (9.1, 9.2, 9.3, 9.4 and 11.1, 11.2, 11.3, 11.4) may be positioned at different heights.

Description

2368384 FURNACE CAR

DESCRIPTION

This invention relates to a furnace car (kiln car).

Furnace cars are used to hold material for firing while it is being dried and fired in a furnace.

They are used especially in the stoneware and ceramics industries, where they are used to hold ceramic goods, for example.

Furnace cars may be used in continuous furnaces, such as tunnel furnaces, as well as in discontinuous furnaces such as bogie hearth furnaces.

The goods for firing are usually placed on the furnace car following the shaping operation, and then they are sent by furnace car to the remaining treatment process, in particular the drying and firing operations.

The goods remain on the same furnace car during practically the entire operation.

For movement of the furnace cars, they have on their bottom side wheels with which they can roll on a rail system These furnace cars, like railroad cars, can be moved back and forth along the linear direction of rolling of the wheels Movement across this direction of rolling is impossible To do so, the furnace car must be displaced on a rotating platform, for example.

In this connection, the direction of rolling is an imaginary line along which the furnace car can move, i.e, along which it can roll without having to be displaced on to another conveyance medium.

The object of this invention is to make available a furnace car which can move along more than one direction of rolling.

This invention solves this problem in an amazingly simple manner by means of a furnace car having wheels on which the furnace car can roll, whereby the axes of the wheels are arranged in two parallel horizontal planes, within each plane the axes run parallel to and at a distance from one another, and the axes in one plane run at an angle of 90 degrees to the axes of the other plane.

According to one embodiment, at least two wheels are arranged rotatable along each axis.

Thus, this makes available a furnace car of the type described above which can be moved along more than one direction of rolling without having to be moved on a transport platform or along any other transport medium.

The axes of the wheels are arranged in two parallel planes, and these planes may be arranged either at a distance from one another or not, i e they may be superimposed.

An axis in the sense indicated above is understood to be an imaginary geometric straight line representing the axis of rotation of the wheels.

Within each plane the axes run parallel and with a distance to each other Just two axes may be provided in one plane But more than two axes may also be provided in one plane.

The axes in one plane run at a right angle ( 900) to the axes of the other plane The furnace cars can thus be moved in two directions of rolling at right angles to one another.

In each plane, the wheels of the axes may be arranged one behind the other in the direction of rolling within one plane This embodiment thus corresponds to the typical arrangement of wheels for a furnace car in this plane, like those on a railway car If the wheels are designed accordingly in both planes, then the furnace car has two sets of wheels more or less, each with four wheels of the type typical for a furnace car and arranged at an angle to one another.

With a furnace car according to this invention, for example, it is possible to first transport the kiln car through the furnace along the direction of rolling of the wheels by means of the wheels arranged in one plane, and then by means of the wheels arranged in the other plane, to transport the kiln car along their direction of rolling on another track, e g, a return track.

The furnace car may have, for example, an essentially rectangular horizontal cross section At the same time, one direction of rolling may be along the longitudinal axis of the furnace car while the other direction of rolling is along the transverse axis of the furnace car, so the axes of the wheel sets are at an angle of to one another in the respective planes.

In this case, the furnace car may be transported through the furnace crosswise, for example, i e, with its greater length perpendicular to the direction of rolling, and then guided lengthwise, i e, with its shorter length perpendicular to the direction of rolling, on a return track running parallel to the furnace.

In this case, one advantage is the small amount of space required for the return track.

This invention is explained in greater detail below on the basis of a highly schematized embodiment.

The figures show:

Figure 1: a furnace car 1 in a side view, Figure 2: a furnace car in a bottom view, and Figure 3: a tunnel kiln and a return track running parallel to it.

The furnace car 1 according to Figure 1 has a furnace car superstructure which is labeled as 3 in the diagram (and has a refractory ceramic lining 3 F) which is mounted on the furnace car substructure 7 by means of fastening elements 5 During the firing operation, the upper side 3 1 of the furnace car superstructure 3 faces the firing chamber of the furnace The material for firing (not shown) can be transported on the upper side 3 1.

Wheels 9 1, 9 2, 11 1 and 11 2 of the furnace car 1 are arranged on the furnace car substructure 7 This side view shows only four of the total of eight wheels which are present in this embodiment (see Figure 2) The additional four wheels here are arranged on the other side of the furnace car 1 in mirror symmetry with the plane of the drawing, corresponding to the wheels 9 1, 9.2, 11 1, 11 2 shown here.

The wheels 11 1, 11 2 are each mounted on the furnace car substructure 7 in such a way that they can rotate about a shaft Each shaft extends along an axis 13 1 or 13.2 The axes 13 1, 13 2 are running parallel to one another and perpendicular to the plane of the drawing and are arranged with a distance between them in a first plane 15.

Another plane 17 extends beneath the first plane 15 and parallel to the first plane 15 The wheels 9 1, 9 2 are mounted on the furnace car substructure in this plane so that they can rotate about a shaft which extends along the axis 19 1 The axis 19 1 runs parallel to the plane of the drawing.

The wheels 9 1, 9 2 are placed on rails 21.

In Figure 2, the furnace car 1 is shown in a top view of the embodiment according to Figure 1, i e, a view of the furnace car substructure 7 as seen from above.

The axle 13 1 of wheels 11 1, 11 3 runs parallel to the axle 13 2 of wheels 11 2, 11 4, with wheels 11 1 and 11.2 and 11 3 and 11 4 being arranged one behind the other in the direction of rolling Q.

The outer periphery of the furnace car 1 describes a rectangular shape whose greater length extends along the direction of rolling L and whose shorter length extends along the direction of rolling Q.

In a tunnel kiln 23 according to Figure 3, furnace cars 1 of the embodiment described above are first rolled through the furnace 23 in the rolling direction Q on wheels 11 1, 11 2, 11 3 and 11 4.

After passing through the furnace 23, the furnace cars are rotated by 900 at the first turning location 25 and then are rolled in the rolling direction Q to the second turning location 27.

Without further rotation, the furnace cars 1 are then rolled back in the direction of rolling L parallel to the furnace 23 via the return track 29 on wheels 9 1, 9.2, 9 3 and 9 4.
