Description

(54) HYDRAULIC PLUG OF TUNNEL FURNACE

t

The invention relates to the production of ceramics and refractories, namely, tunneling (shcham for compression products).

A hydraulic shutter tunnel kiln E is known, containing the water content & the gutter with the butt joints immersed in it, which are glued to the waddisses, the elastic straps from the torsovios. sides and moving end sections of SC

The use of a known hydraulic shutter is associated with additional oriental operations (output). trolleys in the field and employees of the paraphernalia (receivers for sleeping, lifting devices, moving sections, seals). Silver slings are subject to wear, especially due to the constant lateral displacement of the trolley knives relative to; The famous event requires an increase in the overall dimensions of the furnace, which limits its use on operating furnaces.

The closest to the present invention is the hydraulic shutter of the tunnel furnace, which contains a chute filled with lushness with knives immersed in it, attached to the trolleys, and a recycling system with nozzles for supplying a liquid outlet, at the ends of the chute, there are gates to maintain a constant level in the chute C21.

ten

The known gate requires the presence of sluices at the ends in order to ensure a constant level in the gutter, which complicates the introduction of the trolley into the gate.

The purpose of the invention is to simplify the construction by facilitating the insertion of the waggon into the closure.

Claims (2)

The goal is achieved by the fact that in a hydraulic plug of a tunnel kiln containing a liquid-filled trench with knives immersed in it {fixed to the trolleys and a recycling system with nozzles for supplying and discharging fluid, the nozzle 39 for supplying fluid is placed in the middle part gutter, and for removal - on xitsah. With a dynamic pressure relief circuit, the worm is equipped with a grill installed in the pipe for supplying liquid. In order to control the flow of liquid, it is equipped with flexible plates installed in front of the pipe for liquid discharge. FIG. 1 shows (without knives of trolleys) a shutter with partial cuts, general view; in fig. 2 shows section A-A in FIG. 1. The hydraulic shutter contains an outlet 1, to the bottom of which is attached a nozzle for supplying 2 and nozzles for extracting 3 of a liquid. In the pipe for supplying liquid 2 there is an absorber for amylic pressure, for example, a grating 4. At the ends of the forehead 1, flexible plates 5 are installed in front of the pipes 3 for draining the liquid, forming a gap between them through which the knife of the trolley 6 passes (Fig. 2 ). The hydraulic shutter works as follows. The fluid in the groove of the shutter 1 is fed through the nozzle for supplying 2, the dynamic liquid pump is quenched by the grating 4, then the fluid flows in both directions to the ends of the shutter, non-cutting occurs. the slots between the flexible plates 5 and the knife of the trolley 6 and are drained through the branch pipes 3 for removal. Changing the size of the gaps between the flexible plates 5 and the Vagiette 6 knife changes the flow rate. The simplicity of the design of the proposed hydraulic shutter allows the additional devices to be discarded and 6 eliminates the additional operations associated with the insertion (output) of the wafer into the shutter. This ensures a more efficient cooling of the shutter at the same flow rate, the liquid, since the highest temperature is observed in the middle part of the furnace. The use of the proposed valve does not require an increase in the dimensions of the furnace. Claim 1. Hydraulic shutter of a tunnel kiln containing a fluid filled chute with knives immersed in trolleys immersed in it and a recirculation system with nozzles for supplying and draining fluid, in order to simplify the design by facilitating the introduction of the trolley into the shutter, the pipe for the supply of fluid is placed in the middle part of the gutter, and for drainage - on the x. 2. Shutter according to claim 1, that is, so that, in order to quench the dynamic pressure of the liquid, it is equipped with a grid installed in the pipe for the supply of liquid. 3. The closure according to claim 1, which is designed so that, in order to regulate & neither the flow rate of the liquid, the device is equipped with flexible plates installed in front of the nozzles for draining the liquid.
