Description

The invention relates to the field of instrumentation, namely to devices for processing diazomaterials, and can be used for copying documents.

The aim of the invention is to improve the reliability and quality of processing "

The figo shows the device, cut; FIG. 2 is view A of FIG. 1; on fig.Z - device evaporator; figure 4 - dosing device.

A device for processing diazomaterials consists of a base 1 on which chamber 2 is placed. The walls of the chamber are made of heat insulating material. An evaporator 3 is installed in the upper part of the chamber, in contact with a heater 5 placed along the entire plane of the top wall 4, B a shaft 6 of a transport mechanism is installed diazomaterial (not shown) in contact with the liner

7 of the antifriction material, fixed in the base 1 A window is made in the wall of the chamber at its base

8, through which the output material is fed through the material being processed. Inside chamber 2, arcuate pipes made of thermal insulation material are installed in two rows; Vl 9 and 10; At the same time, external guides 9 are fixed at one end at base 1, and at other ends over bottom 8, installed at an acute angle to the vertical of the camera and with the possibility of contact with the shaft 6 in diameter; - but the opposite points about Vnu. -miniuyu Yuphe 10 set1: e .4 with a gap of) to к 1.p & 1 ush} 1M 9 and the ends contact with Rg.lim 6,

21 for the release of ammonia vapors and a U-shaped partition 22 is divided into communicating sections 23 and 24, the bottom of each of which is inclined so that the lower level: the bottom of section 23 is the upper level of the bottom of section 24, B is not; -: A tube 25 is fixed to the point of the U-shaped non-partition 22, the connecting evaporator 3 with the unpressurized part 26 of the tank 11, provided with a stopper 27U. The device is also equipped with a thermal control system (not shown),

The device works as follows

Open the plug 27 and fill the container 26 with the developing agent at 1/2 its height. Liquid, fill the container 26, opens the valve 15 and flows into the container 16. The liquid level in the containers 16 and 26 is leveled. After filling the liquid, the plug 27 is closed. The heater 5 is turned on and, when reaching the operating temperature, the microcompressor 12 is turned on, which creates an increased pressure in the tank 16: 1 in. At that, the valve 15 is closed and the liquid is lifted from the tube 18 to the dropper 13, Flow; i: 1 the boilers are set up with a screw 19 through the drip pan. Through the tube 20 the metered amount of liquid flows to the evaporator 3 and, evaporating from the upper chamber 2 steam layer that strips / ivetav with steam 3vatS1M,

The drive shaft 6 is driven, which rotates along the insert 7, carries the diazo material 28 on B1, and has sent 9 to the shaft with a narrow shaft, then diazomatrix evil due to its stiffness of the link, along the entire length of the gap formed outside 9 and 10 internal guides. Getting into the upper part of the chamber, the diazo material is treated with ammonia para-sh, lowers along the gap to the second contact point of the external directions with shaft 6 and is completely removed from the chamber. If there is an excess of ammonia, it does not evaporate completely and the remaining part of it flows down the slope - The bottom of the evaporator 3 and the outlet tube 25 into the tank 26. During operation of the microcompressor 12, a liquid is used in the tank 16. When the microcompressor is turned off

the pressure in the tank 16 drops, the valve 15 opens and the ypoBeib fluid in the tanks 16 and 26 is equalized. In this case, from the upper volume of the dropper 13 (FIG. A), the liquid returns to the tank 16 by gravity due to gravitational forces. As a result, the supply of ammonia to the evaporator stops. When the microcompressor is turned on, the process is repeated.

The present invention provides a complete and reliable removal of the diazo material from the production chamber. The quality of the treatment is improved by eliminating areas obscured by the guides, since the outer guides are inclined. The system of supply and return of the developing agent eliminates emergency evaporator overflow, and the inertia of the system of delivery of the developing agent is small and ensures its economical use.
