Description

The technical solution relates to the production of foam glass and can be used in the building materials industry.

Known installations that use one-stage and two-stage schemes for the production of block foam glass, in which forms with a charge are introduced into the foaming furnace installed on a large area face [1, 2, 3].

Closest to the claimed technical solution is the installation for the production of foam glass blocks, containing a foaming furnace and annealing furnace, detachable forms vertically mounted on a smaller face, transfer trolleys, a form pusher, transport lines, a charge hopper [4]. Despite its high performance, such an installation has considerable dimensions under optimal operating conditions (annealing furnace over 100 m), which requires appropriate production areas and is not always optimal in terms of minimizing the time required for transportation and mold preparation.

The purpose of the technical solution is to expand the functional and technological capabilities of the installation, increase operational reliability, and optimize its weight and size characteristics.

This goal is achieved by the fact that the installation for the production of foam glass blocks containing a foaming furnace and annealing furnace, metal molds mounted vertically on one of the smaller faces so that foaming of the charge occurs parallel to the plane of the largest face of the mold; transport path for moving molds; transfer trolleys , pushers of forms, the hopper-dispenser of the foaming mixture, is equipped with additional annealing furnaces, which are loaded alternately, and a line for the rapid return of forms. The essence of the technical solution is illustrated by the drawing, which shows a diagram of the proposed installation for the production of foam glass blocks.

Installation for the production of foam glass blocks contains a foaming furnace 1, annealing furnace 2, vertically mounted forms 14 on a stand, a self-propelled transfer trolley with a receiving chamber and a heating system 5, self-propelled transfer trolleys 4, 10, 18, pushers of forms 3, transport lines 6, 7 , 15, belt conveyor 9, roller conveyor 11, section for extracting blocks from forms 8, section for preparing forms 12, 16 feed hopper with a charge and a dispenser 13, 17. Plots for machining, storage of blocks and preparation of the charge are not shown.

Installation works as follows.

The main operating mode of the installation. The foaming mixture is loaded using a dispenser 13 into molds 14, which are transferred by a transfer trolley 4 to the loading zone of the foaming furnace 1. The load is carried out cyclically every 3-5 minutes with a pusher 3. At the outlet of the furnace 1, the trolley 5, which has a receiving chamber with a heating system, receives forms with blocks and transports them to the loading zone in the annealing furnace 2, which are loaded sequentially according to the scheme 1-2-3-1-2-3 with pushers 3. Structurally, the forms have adjustable stiffness, selected so as not to destroy the blocks upon cooling. At the exit of the furnaces 2, the carriage 10 receives a stand with molds from which foam glass blocks are removed at section 8 and sent to a conveyor 9 for machining or to a warehouse. Free forms with a stand using the pusher 3 and the conveyor 11 are supplied first to the preparation area 12, and then to the charge charge. The arrows show the movement of forms and finished blocks.

Additional operating mode of the installation. The operation of the installation in the main mode requires a large number of forms that fill both the foaming furnace and all annealing furnaces. With a limited arsenal of forms or with the release of a small batch of products, the installation design provides for the possibility of annealing blocks without forms. For this purpose, the installation is equipped with an additional line for the rapid return of molds - the foaming furnace 1 is unloaded to the trolley 18, where the molds are opened, the foam glass blocks are loaded into the receiving chamber of the trolley 5 with subsequent annealing in the ovens 2, and the free molds are fed by the trolley 18 to preparation 16 and loading charge 17.

In the event of an emergency, the design of the installation allows reorienting the transport flows of the molds, disabling one of the annealing furnaces, sending the molds for annealing according to a temporary pattern to other furnaces.

The choice of the specific dimensions of the annealing furnaces is determined by the required plant capacity, the presence of the corresponding production areas, the physicochemical and rheological characteristics of the annealed material, and, for example, for a four-row arrangement of molds with a size of 500 × 500 × 120 mm, with an average cooling rate of foam glass blocks of 0.7 deg./min varies depending on the number of furnaces within 19-123m (table).

The introduction of additional annealing furnaces and a mold return line into the production scheme of block foam glass expands the functional and technological capabilities of the installation, increases its operational reliability, allows optimizing weight and size characteristics, turning the installation into a universal tool for the technological conversion of a wide range of glass raw materials into high-quality heat-insulating products.
