Description

Electro-pneumatic command apparatuses for hydroabrasive processing of products coming from a bunker and moved by a conveyor from one working position to another are known. However, these installations do not provide sufficient processing quality, since the products in nph are not moved.

In the installation described, this disadvantage is eliminated due to the use of paddle drums installed above the main conveyor, which are associated with rotation opposite to the direction of movement of this conveyor and cyclic reciprocating movement perpendicular to the direction of its movement. Apply these drums to mix products at all processing positions; degreasing, sandblasting, washing, passivation and essence. In addition, an additional nutrient coiler was used in the installation, feeding portions of the product from the bunker to the main conveyor.

FIG. 1 image 15a installation, side view; in fig. 2 - same view

The base / unit is an all-welded bath divided into the corresponding working position of the section: degreasing section 2, water sanding section 3, washing section 4, passivation section 5, and essence 6. Each section has water, compressed air and electricity.

The main conveyor is made in the form of a welded frame 7, on which drive 8 and tension 9 drums, roller bearings 10 with perforated mite // conveyor and drive shafts of mixing blade drums 12 are mounted.

Above the hoop / welded box 13 is installed, divided into the same number of sections as the base. In these sections, drums 12 driven by a single drive and pneumatic number 1.34583-2 motor 14, which inform the drums in a cyclical reciprocating motion in the direction perpendicular to the direction of movement of the belt 11 of the main conveyor, are mounted.

In addition, the described installation is equipped with an additional feed conveyor 15.

The products to be cleaned are placed in the bunker J6, from where they freely enter the conveyor belt 15, the capacity of which is controlled by changing the cross section of the discharge window of the bunker 16. Thereafter, the drives of the main conveyor, transmitting parts from one working position to another, paddle drums 12, circulating pumps 17 servicing jet collectors 18 of sections 2 and 5 of degreasing and passivating, and driving a mortar pump 19 supplying a water-jet mixture to sandblaster 20. It includes the water supply to the part 4 washing section and the supply of compressed air to sections 3 and 6 of the sandblasting and drying unit. Finally, the feeding conveyor 15 is turned on, with the start-up of which the automatic operation of the installation begins.

The conveyor 15 feeds a portion of parts to the moving belt 11 of the main conveyor. By entering the degreasing section 2, the parts fall into the first drum 12, the direction of rotation of which is opposite to the direction of movement of the main conveyor belt. The drum blades carefully move the parts washed by the degreasing liquid coming from the jet nozzles. After the time predetermined by the cycle has elapsed, a time relay is triggered, including the electromagnetic pneumatic valve of the pneumatic cylinder 14 of the drum 12 and the lifting of this drum occurs, releasing the parts for further movement together with the belt 11, which enters section 3 of the sandblasting unit, the drum 12 installed in this sections. Here, an operation similar to the previous one takes place, only instead of degreasing, hydrodisturbing is performed. During the transition of the batch of parts from the degreasing section 2 to the hydro-sandblasting section 3, the first mixing blade drum 12 is automatically lowered and the feeding conveyor 15 is simultaneously turned on, feeding the next batch of parts to the // main conveyor belt, and to the degreasing section 2. In this way, sequential cleaning of the parts is automatically carried out.

Claims (2)

1. Installation for automatic hydroabrasive cleaning of products coming from the bunker and moved by the main conveyor from one working position to another, characterized in that, in order to ensure the movement of the products during their processing, at all working positions - in the degreasing sections, hydro sandblasting, washing, passivating and drying - the blade drums are installed above the main conveyor, which receive rotation in the opposite direction and cyclical reciprocating movement in the direction perpendicular to Moving the main conveyor. 2. In the installation of claim 1, the use of an additional nutrient conveyor for batch feeding of products from the hopper to the; -blavny conveyor.
