Description

In the proposed device for the introduction of colloidal graphite into the steam boiler, in order to protect the boiler from scale, namely, in the glass connected with the reservoir of colloidal graphite and with the water intake pipe, a sleeve is inserted with annular channels interconnected by recesses with the adjusting screw screwed into it having transverse and longitudinal channels, of which the latter communicates with an injector that sucks graphite into the boiler; in a modified device, instead of a regulating screw, the glass is filled with adjacent inserts fitted with end sockets and central channels that expand in the direction of movement of colloidal graphite.

In FIG. 1 shows a vertical section of the device, FIG. 2 - a general view of installing it; FIG. 3-vertical section of the device with inserts; FIG. 4 is a general view of installing it.

The device (Fig. 1 and 2) consists of a glass cup A, in which a sleeve B is screwed, having annular undercuts - an external A - / {and internal I-I, which are interconnected by radial channels / ;. A adjusting screw N having channels, a longitudinal axial o and a transverse rf, is screwed into the sleeve B, and at the end provided with a cap with a hole about one millimeter in diameter. When fully screwed in, the adjusting screw with its conically sharpened end is inserted into the correspondingly shaped part of the hole at the bottom of the glass. From the bottom of the cup with the turned out nest for placing the check valve P, the cover is threaded, the shank of which is screwed into the pipe branch pipe t, which is connected to the injector body at the place where the water purification grid is placed. The fittings E yi D, screwed into the walls of the glass, are connected with pipes; fitting E is a reservoir filled with graphite with cavity I of sleeve B, another D-water intake pipe of the injector with a cavity of glass A.

At the moment of the start of water injection, the steam fills all the chambers of the injector, goes through the pipelines and lifts the valves P, closing the entrance to the device.

Then, when the injector starts working, valve P sits down into place under the influence of suction force, and partly of its own weight, and graphite from the reservoir

through the tube through the fitting E, the undercut k, the channel n, the annular cavity I and the channels d and o begin to be sucked into the injector and fed into the boiler.

To reduce the flow of graphite, it is necessary to raise the screw N; then, due to the connection of fitting I) with the water intake pipe and with the ring pblost & g, the suction is slow and the flow of graphite will slow down. Turns of the screw for the desired degree of supply are marked by risks on the top of sleeve B. Maintenance of the device is reduced to filling with a graphite in the reserve tank and setting the adjusting wine N to the desired flow.

The modified device shown in FIG. 3 and 4, consists of a glass A, filled with inserts k, depending on the amount of graphite supplied. The inserts have end sockets and conical channels with, with, with the narrow side, these channels are directed against the movement of colloidal graphite, in order to slow down the movement of fluid. The need to slow down the flow of graphite and the flow of graphite is caused by the fact that graphite is supplied in relation to the pumped water of an extremely small amount: for example, 7 grams of graphite is fed to a ton of water. The nozzle J connects the instrument to the injector body. As soon as the injector injects water, now, through the tube L of the reservoir T with colloidal graphite, the graphite is sucked into the injector, and from there into the boiler. Adjustment is done / once.

I, precisely by following the locomotive, determine by a fixed way the required j quantity of graphite consumption and the required number of inserts is determined.

The subject of the patent.

1. A device for inserting colloidal graphite into a steam boiler, characterized by using glass A, provided in the bottom with an opening e, leading into the pipeline w connected to the injector, in which glass L by means of an internal sleeve B and screwed into the adjustment screw N annular cavities are formed: 1-for water and I-for colloidal graphite, communicating with hole e with a channel in said screw, also intended for separating the hole with cavity Y by inserting a conically sharpened end of the screw in respectively the completed part of the hole, for which automatically, when filled with pipeline in steam, serves as a check valve P..

2. Variations of the device described in paragraph 1, characterized in that the glass A (FIGS. 3 and 4) instead of the adjusting screw N is filled with inserts k, adjacent ends and equipped with, each, an end socket and a center channel expanding in the direction of colloidal graphite movement.
