Description

The invention relates to the production of building products and structures, namely, devices intended for the heat treatment of concrete and similar products in vertical cassettes or thermoforms.

Known thermal compartment cassette installation, divided by a system of partitions into a number of interconnecting cavities [ί].

The closest of the Known by the technical essence and the achieved result to the invention is the thermal compartment of the cassette installation for the heat treatment of concrete products, including heating metal sheets, end walls, branch pipe, steam supply and condensate drainage and horizontal partition walls forming the directional flow of the heat carrier [2 /}.

A disadvantage of the known devices is the low efficiency of heat transfer from the coolant to the product.

The aim of the invention is to increase the efficiency of heat transfer.

This goal is achieved by the fact that the heat compartment of the cassette installation for heat treatment of concrete

products, including heating metal sheets, end walls, ι horizontal partition walls and pipes for steam supply and condensate drainage, are provided with a vertical partition forming an additional cavity with the end wall, and a diffuser in which the steam nozzle is placed; on a vertical partition.

Fig, 1 shows a thermal compartment, a general view; see 2 — node I in FIG. one.

The heat compartment includes heating metal sheets 1, end walls 2, horizontal partitions 3, which divide the internal volume of the compartment into a number of interconnecting cavities, branch pipes for steam supply 4 with nozzle 5 and condensate drain 6, vertical partition 7 forming the end wall 8 additional cavity, and the diffuser 8, which forms with the nozzle '

5 ejector.

Works thermal compartment as follows.

Heat carrier, such as steam, is supplied to the internal volume of the steam room.

heads through nozzle 5. In the initial period of temperature rise, intense heat transfer occurs and almost all the steam is converted to condensate, which flows through the nozzle

6. With the further flow of steam through the nozzle 5, it passes through the diffuser 8, fills the First 'cavity' formed by the upper wall of the compartment and the upper horizontal partition, then passing between the rest of the horizontal partitions, the steam enters the additional cavity formed by the end wall 2 and a vertical septum 7, and under the influence of the ejection effect when steam is supplied from the main steam line, it is drawn back into the first cavity.

Thus, the steam is constantly circulating inside the vat compartment. 20

Using the described thermal compartment allows you to increase

to the product and simplify the design and operation of the installation.

Claims Thermal compartment of a cassette installation for heat treatment of concrete products, including heating metal sheets, end walls, horizontal partition walls and nozzles for steam supply and condensate drain, which differs from me, that, in order to catch the efficiency of heat transfer, it is provided with a vertical partition, forming an additional cavity with the end wall, and a diffuser, in which the nozzle of the nozzle 15 is placed. For supplying steam, the diffuser is mounted on a vertical partition.
