DE2827590A1 - Drying chamber for tumble-galvanised objects - has open-top container for receiving, tilting and rotating work basket - Google Patents

Abstract

The drying chamber comprises a container (2) capable of receiving a basket (1) for the objects to be dried, particularly tumble-galvanised components. The container is arranged so that the basket can be tilted and rotated (4) about its longitudinal axis. The arrangement may permit filling or emptying the basket whilst inside and outside the chamber. The basket or the contents may be introduced into the chamber from the top (3). The basket may be tipped for removing the contents through the bottom of the chamber. The chamber may be provided with fans and a heater.

Designation: Area of application:

Dryer for metallic bulk parts and / or for other bulk goods.

The invention relates to a device for drying, in particular of metallic fiassentteile, whose surface has been refined or treated beforehand.

Purpose:

The surface of metallic parts by mass becomes mainly treated or refined in so-called drums. After the last treatment stage (rinsing bath), these parts must be dried will. In many cases this is done by centrifugation. Since the material to be dried does not have its position in simple centrifuges changed, very long drying times must be accepted for scooping parts. Another disadvantage is that the protective layer or the parts themselves are still soft forces occurring in the centrifuges are damaged.

When drying with warm air, the material to be dried must be repositioned several times, because otherwise stains will form. At the same time, scooping parts are emptied and the drying time is considerably shortened.

Object of the invention:

The invention is based on the object of sensitive and scooping items to be dried to be gently tumbled and dried with warm air.

Solution:

According to the invention, this object is achieved by a drying chamber with a device for receiving a shopping cart, which tilts the shopping cart and rotates it about its longitudinal axis. The items to be dried are rearranged by the Schickanen built into the shopping cart. Warm air is blown at high speed onto the items to be dried in the basket, which is open at the top. The water evaporates in the process.

Some of the water can drain through the perforations in the wall and bottom of the basket. There If this basket rotates very slowly, no centrifugal forces act on the items to be dried. The mechanical stress on the items to be dried is minimal.

An embodiment of the invention is shown in the drawing and is described below described in more detail.

It show: Figure t:

The basket (1) when loading and unloading the dryer. The shopping cart (1) will inserted vertically into the holding device (2) during loading.

Figure 2:

The position of the basket (1) and the holding device (2) during drying.

The cover (3) is mechanically connected to the holding device (2) so that when the Cover the holding device with the shopping cart is pivoted by 45 °. In this inclined Position is set by the gear motor (4) of the basket (1) and the holding device (2) around the inclined axis rotated.

A mixture of fresh air and exhaust air is sucked in by the fan (7) and heated in the air heater (6) and then blown onto the material to be dried via the air jet nozzle (5).

After drying is complete, the basket (1) and the holding device (2) become vertical again placed and the shopping cart (1) lifted upwards.

Figure 3:

Another way of emptying the shopping cart.

At the end of the drying process, the holding device (2) and the basket (1) are placed on the Air nozzle (5) on the opposite side swiveled so far that the items to be dried are out of the basket (1) may fall out. During the emptying phase, the shopping basket (1) also rotates around its Longitudinal axis.
