Description

The invention relates to devices for spraying and applying liquids on the surface of products and can be used to paint products, for example pipes.

The aim of the invention is to improve the safety of service and fire safety.

FIG. 1 shows an installation for painting products; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one; in fig. - installation diagram.

The installation contains a rectangular chamber 1 with an opening 2 in the upper wall 3 for inserting the stand k with articles 5 and grooves 6 in the side walls 7. Along the side walls 7 are guides 8 with driving carriages 9 mounted on them. collectors 10 with paint sprayers 11. Spray heads 12 paint sprayers

11 are inserted into the chamber 1 through the slots 6 in the syukovye walls 7. The collector bars 10 are connected by hoses 13 to the tanks C for paint. Ookovy walls 7 adjoin casings 15 and form with them isolated compartments in which guides 8 with carriages 9 and collector rods 10 with spray guns 11 are placed.

The grooves 6 in the side walls 7 are closed with flexible curtains 16. The opening 2 in the upper wall of the chamber 1 is closed with sliding lids 17, equipped with a drive made in the form of pneumatic cylinders 18 with a pneumatic distributor 19. The pneumatic distributor 19 is connected to the compressed air supply line 20 with a pipeline 21 equipped with the air cleaner 22, the moisture separator 23 and the shut-off valve 24.

Paint tanks and paint sprayers 11 communicate with the main line

7.0 compressed air through pipe 25 with a valve 26.

On the covers 17 and the side walls 7, limit switches 27, 28, 29 are mounted in the control circuit of the reversing motor 30, which serves to move the carriages 9 along the guides 8 through the circuit 31. The stand C is made in the form of a frame with vertical struts and a pin Mi 32 dl - installation products. The installation is equipped with a ventilation system including hydraulic filters 33 and fans 3, and an emergency protection unit including a gas analyzer 35 and a fan 36. The installation has a control panel 37 containing a manual and automatic control unit, a time relay 38 and a pneumatic valve 39.

The installation works as follows.

The stand k with the products 5 fixed on it is lowered into the chamber 1 through the open opening 2 in the upper wall. Under the action of the weight of the product stand, a lever (not shown) of the control unit is activated and the compressed air is supplied to the pneumatic distributor 19. The pneumatic cylinders 18 close the covers 17. When the cap 17 closes, the limit switch 27 turns on the reversing motor 30, the compressed air supply valve 26 tanks 1 and spray guns 11. In the process of moving the carriages 9 with the spray guns 11 along the side walls 7, the spray heads 12 paint the surface of the products 5 on all sides and along the entire length. When the carriages S reach The limit switch 28 is triggered, which switches the engine 30. When the carriages 9 return to their initial position, the limit switch 29 switches off, providing the engine 30 and the shut-off valve 2-1 to turn off, time relay 38 switches on and the air distributor 19 switches. spirit and paint to the spray gun 11 is terminated.

After a set period of time, the signal of the time relay 38 turns on the fans 3, and the pneumatic cylinders 18 open the covers 17. The stand with the painted products is removed from the chamber 1. When manually operated, the installation for switching on the compressed air supply to the pneumatic distributor is performed by opening the pneumatic valve 39. After opening the covers 17, a stand b with articles 5 is installed, then the pneumatic valve 39 is closed. The covers 17 are closed. The drive of the carriages 9 and the supply of compressed air to the tanks 1 and the spray guns 11 are turned on. After the painting is over, the pneumatic valve 39 is opened. The covers 17 are opened. Then, a stand with colored articles is removed from the chamber.

Equipped with enclosures and placing guides with carriages and paint sprayers in the isolated compartments formed by enclosures and side walls and making slots in the side walls of the chamber with flexible shutters helps to limit the spread of paint spray to the environment, which improves sanitary and hygienic conditions for staff and increases fireproof installation.
