SU9997A1 - Cascade heater for feedwater installed in the steam space of the boiler - Google Patents

Description

The invention relates to cascade heaters for feedwater installed in the steam space of a boiler and consisting of a series of grooved elements arranged one above the other.

In order to simplify the design of such preheaters and make them easily collapsible, as well as to improve heat transfer, separate cholas, two or uri zholob elements, are made with ends bent up and arranged in a checkerboard pattern. Water flows through the preheater, at which it stagnates in its elements and flows through their lateral edges at a speed much lower than that with free flow. Due to the particular changes that undergo the direction and speed of the water, the latter is sprayed into small streams, and steam everywhere has free access to water particles. By (the ice is not only warmed up, but also cleaned, since the temperature at which it comes from the injector or pump in the heater

rises rapidly to a temperature that precipitates the dissolved constituents.

Zholoba can be made of

each square, there are three parallel water streams, two at the edges and three other parts of water at the top. flows down the side walls of the squares. A box or semicircular chute can also be used. A sprayer is installed in front of the preheater, which supplies water in the form of a large number of thin streams. The gases released from the feed water are collected at the top in a suction bowl. At this point, it is good to remove them, for which a steam boiler with a heater can be placed, for example, on a boiler having a second steam boiler for steam removal. Then the gases, through a pipeline, are supplied from a steam boiler with a heater to the steam boiler for removal of steam and go along with the steam to the machine. The solids released from the water are also sent, as defined by the patent of the Fritz 9997 patent by Wagner and E.

to the patent and the other firm "K. A. Fez and Son (S. A. & Sohn),

in the city of Berlin - Lichtanberg, Germany, on September 27, 1927 (for reference. certificate. No. 19105).

The real inventor is In-et T. Langenberg (T. Langenberg).

Priority from October 1, 1926, on the basis of art. 4 Soviet - German agreement on the protection of industrial property.

On granting a patent published June 29, 1929. The patent has been granted for 15 years dated June 29, 1929.

The proposed invention relates to centrifugal continuous action, both plates of which are pressed to each other by means of a hydraulic press, and have the goal, by connecting these plates with a piston and a hydraulic press cylinder, to avoid the axial forces arising in existing centrofuges and forcing of this, make the centrifuge bed powerful enough.

In FIG. 1 shows a longitudinal section of the centrifuge in FIG. 2 - longitudinal section through the centrofugu, working hundred.

According to FIG. 1, the upper cone-shaped lattice plate 1 is connected to a flange-like expanding field by a drive shaft 2, through which the material to be centrifuged is fed.

The bristle plate 1 is connected by centering the ribs 4 to cylinder 5, guided by cylinder 6 of another lattice plate 7. In cylinder 5

there is a piston 8 connected by a pin 9 with a lower lattice plate. The trunnion 9 passes through the hole in the bottom of the cylinder 10 and this passage is sealed by means of a gasket 11.

If the oil or some other liquid is supplied to cylinder 5 through the axial hole 12 of the trunnion 9, then the edges 14 and 15 of the trellis plates 1 and 7 are pressed together and the centrifuge closes without pressure on the stopper.

The liquid constituents of the material fed into the centrifuge during rotation of the centrifuge can be ejected through the openings 13, while the dense constituents remain in the drum.

If the pressure-producing fluid is released from cylinder 5, the lower lattice plate is lowered by its own weight, as a result of which a gap is formed between the edges 14 and 15 and dense components can be thrown out through the generous part.

According to FIG. 2, the cylinder 5 is connected in a similar manner by means of the ribs 4 to the grid plate 1. A pin 9 connecting the porsche 8 to the lower grid plate is made in the form of an Irivod shaft. The shaft is located in the supporting bearing 16 with a conventional buffer device. The lower end of the shaft 9 is located in the usual way in the under of the Tunic, which is loaded only with its own weight of the centrifuge, but not with axial pressure when centrifuging.

In order for centrifuging, as shown in FIG. 2, the edges .14 and 15 were moved away from each other after removal of the pressure producing fluid from the cylinder 5, between the bottom of the cylinder 10 and the lower lattice plate 7 a screw spring 22 was placed, raising the vertical axis: (a new lattice cup 1.

Subject Pdtent.

1. A continuous centrifuge, the two plates of which are pressed to each other by means of an axially arranged hydraulic press, characterized in that one plate is connected to the cylinder and the other to the press piston.

2. The form of execution of the centrifuge indicated in paragraph 1, which differs, and with the fact that one of the plates is equipped with a guide 6 for articulated c. another plate cylinder & press.
