Abstract

Zařízení pro současné sušení a třídění zrnitých hmot ve fluidní vrstvě Je konstruováno tak, že do fluidní vrstvy Je ponořena přepážka s otvory a/nebo mezerami, která odděluje jemné částice od hrubých. Uvedená přepážka se v zařízení otáčí, vibruje nebo posouvá. Přitom po nepohyblivé přepážce s otvory a/nebo mezerami, která je další variantou zařízení podle vynálezu, se pohybuji svislé nebo šikmé děrované přepážky, kterými se vynášejí hrubé částice z fluidní vrstvy. Ve fluidní vrstvě nad uvedenou přepážkou s otvory a/nebo mezerami jsou umístěny částice větších rozměrů, než je zpracovávaná. zrnitá hmota. V prostoru pod přepážkou, ponořenou do fluidní vrstvy, je rovněž do fluidní vrstvy ponořen teplosměnný povrch. Výhodou zařízení podle vynálezu je, že ve fluidní vrstvě lze sušit částice, které jsou ve vlhkém stavu lepivé, tvoří shluky nebo obsahují částice, které by po sušení nefluidovaly, protože jsou příliš velké. Další výhodou zařízení je vysoká intenzita sušení a tím i jeho malé rozměry. Konstrukce a použitelnost zařízení jsou popsány třemi příklady s přihlédnutím ke třem obrázkům.Device for simultaneous drying and sorting of granular materials in a fluidized bed It is constructed in such a way that a partition with holes and/or gaps is immersed in the fluidized bed, which separates fine particles from coarse ones. The said partition rotates, vibrates or moves in the device. In this case, vertical or inclined perforated partitions move along the fixed partition with holes and/or gaps, which is another variant of the device according to the invention, through which coarse particles are removed from the fluidized bed. In the fluidized bed above the said partition with holes and/or gaps, particles of larger dimensions than the granular material being processed are placed. In the space below the partition, immersed in the fluidized bed, a heat exchange surface is also immersed in the fluidized bed. The advantage of the device according to the invention is that particles can be dried in a fluidized bed which are sticky in the wet state, form agglomerates or contain particles which would not fluidize after drying because they are too large. Another advantage of the device is the high drying intensity and thus its small dimensions. The design and usability of the device are described by three examples with reference to three figures.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for the mechanical protection of a welding torch in an electro-arc welding, comprising a support portion of a welding torch, power supplies, flanges, shear pins. At present, mechanical protection of welding torches is known, in which the welding torch with the supporting part is attached to the kinematic chain of the manipulator or robot by springs or friction joints. Such a solution protects the mechanical welding torch only in a direction perpendicular to its axis. There is no welding torch in the direction of its axis. The relative movement of the welding torch in this direction is destroyed.

If, in the case of the relative movement of the welding torch and the weld in the direction perpendicular to the welding torch axis, the mechanical protection prevents its damage, it is then necessary to set the welding torch in the flood position so that its welding trajectories and especially its welded joints do not have to be reprogrammed. Sometimes it is advantageous to re-create a motion program because it takes longer to set a motion program.

These disadvantages are largely eliminated by the invention. SUMMARY OF THE INVENTION The essence of the invention lies in the design of the mechanical protection of the welding torch for electro-arc welding. The device for mechanical protection of the welding torch in electro-arc welding consists of the supporting part of the welding torch, the energy supply, the flange and the shear pins. The shear pins anchored in the flange are inserted with their ends into the openings in the torch body, it being preferred that the shear pins can be adjusted in the direction of their axis.

The device for mechanical protection of the welding torch according to the invention has several advantages. It protects the welding torch against damage in all directions of mechanical impact to the welding torch. By replacing the shear pins with repeat accuracy, the welding torch is placed in the initial position set before impact, thereby reducing the welding time. The design is simple, it does not complicate the technological head, thus ensuring a low weight of the head and its reliability An example of the mechanical protection of the welding torch is shown in the attached drawing, where the figure represents a partial view of the mechanical protection.

The device for the mechanical protection of the welding torch in the electro-arc welding has shear pins 1 anchored in the flange 2 and are inserted with their ends 3 into the holes 4 in the torch body 5, it being advantageous if the shear pins 1 can be adjusted in the direction of their axis 6.

The device for the mechanical protection of the welding torch in the electro-arc welding of the invention, consisting of the support part 8 of the welding torch 5, the energy inlet 9, is attached to the kinematic chain of the manipulator or robot, which moves the welding torch 5 according to the predetermined path motion. . If there is an obstacle in the defined path of the burner 5, the torch body 5 will strike, causing the shear pins to break and release the welding torch from the flange 2 to prevent damage. By replacing these pins 1 and positioning the torch body 5 in the axis direction 1, repeated accurate alignment of the torch body 5 in its support portion 8 is achieved.

The device for the mechanical protection of a welding torch in an electro-arc welding process according to the invention is applicable to machine and automatic welding of all types of welds, especially when welding by industrial robots.
