Problems solved by technology

Small and medium-sized nozzles are used in the thermal drying process, requiring the operator or the mechanical arm to adjust the blowing angle. The drying process not only takes a long time and consumes more heat energy, but also cannot be quickly

Example Embodiment

[0023] Example 1

[0024] See Figure 5 , Rings a manual or mechanical robot of the present invention will be lifted and placed in a fixed waste paint bucket 10, the shutter 2 from the casing inner wall 10 from the waste paint bucket to 85mm, from the bottom of at least 100mm. The 3 upper airways through the center hole of the fixed heat source contact 11 and the outer tube 7 is integrally connected to the screw. Subsequently, through the hot air, hot nitrogen or hot steam 10 to heat the purge waste paint bucket.

[0025] See Image 6 , Introduced from the nozzle hole 3 under the center hole of the hot gas passage filled with gas waste paint bucket bottom 10, the nip 10 between the baffle extended housing 2 and the waste paint bucket 12 flows out quickly, in the process of waste paint away by evaporation volatiles inner wall surface of the tub 10, the final completion of the rapid drying process. The average temperature of the wall surface of the center hole 3 of the airways than th...

Abstract

The invention discloses a nozzle for hot drying of a waste paint bucket. The nozzle is characterized in that the hot drying nozzle is composed of a central hole air passage sleeved in a baffle shell, the baffle shell is a thin-wall barrel, and the bottom and the top of the baffle shell are respectively provided with a through hole; and an air nozzle, with a flange, at one end of the central hole air passage is arranged on the through hole at the bottom of the baffle shell through a lower gasket, and an air inlet, with an external thread, at the other end of the central hole air passage is fixed on the through hole at the top of the baffle shell through an upper gasket and a nut; Compared with the prior art, the nozzle has the advantages of being capable of rapidly and efficiently drying the waste paint bucket, simple in structure, low in manufacturing cost and convenient to use, on the premise that the heat drying effect is not affected, the surface air speed of hot air with the stable temperature passing through the steel bucket wall is increased as much as possible, the pressure drop in the whole process is reduced, and the time needed for drying is shortened; and operation actions and processes required by an operator and a mechanical arm are reduced, and shells of different sizes can be replaced according to the actual types of scrap steel buckets, so that the nozzle is suitable for batch drying treatment of the scrap steel buckets.

Description

technical field [0001] The invention relates to the technical field of paint bucket cleaning and recovery, in particular to a nozzle used for thermal drying of waste paint buckets. Background technique [0002] At present, the disposal of a large number of waste paint buckets produced in the painting operation of the shipbuilding industry mainly includes dry grinding and wet cleaning. Before dry grinding and disposal of waste paint buckets, the waste paint buckets need to be dried. Due to the small blowing area of ​​conventional gas hot air nozzles in thermal drying applications, it is only suitable for rapid introduction of heating systems with small and medium holes, and enlarging the nozzles will cause energy waste. However, the opening and volume of scrap steel barrels are large, and only the bottom and surface are contaminated with volatile solvents and pollutants. Rapid drying only requires hot air to quickly blow the bottom and surface. The inner surface of the steel...
