    权利要求:
    Claims (2)
    [1]
    The invention relates to installations for the production of molded polystyrene foam units, mainly from hot polyurethane foam, and can be used in various industries. Closest to the present invention is a plant for the manufacture of products from expandable, polymeric materials, containing a rotary drive table with detachable forms located on it, connected through a system of connecting and distributing pipelines for water and steam and cooling water with centrally located the table axis of the distribution head 1. The disadvantages of this installation include the possibility of steam shocks and the destruction, thereby, of connecting cooling pipes or molds at cooling of the latter with running water, as well as the possibility of corrosion in the cooling pipes, which reduces the service life of the installation elements. The purpose of the invention is to increase the reliability of the installation and produce it. . This goal is achieved in that the installation for the production of foaming of polymeric materials, contains a rotary drive table with dismountable forms arranged on it, connected through a system of connecting and distribution pipelines for supplying and discharging steam and cooling water with the distribution grid located along the central axis of the table head, equipped with an interconnecting and distribution piping system with a cooling water preparation unit made in the form of a tank for ndensata, collection of cooling water and a refrigerator connected through a pump for pressurizing the cooling water with the collection. FIG. 1 shows the installation, top view; FIG. 2 is a cross section A-A in FIG. one; in FIG. The principle piping for supplying and discharging heat-transfer agent (steam) and cooling water with appropriate external sources of supply; in fig. 4 - the form with the lid open and the system of coils, rear view. The installation contains a drive rotary table 1 with forms 2 installed on it along its perimeter (the number of forms can be any: 6, 8.12 or more). Table 1 contains a star-shaped support frame 3 with transverse struts 4 and 5, as well as nodular located along the central axis of the stand. slab b. On the lower side of the supporting frame 3 along the outer perimeter, almost under the forms 2, a closed circular running rail 7 is installed with a toothed crown 8 on the inner side of the rail 7. The running rail 7 is supported on several driving wheels 9 fixed in the foundation 10 by means of supports 11 and is provided in motion by the engine 12, the power take-off gear 13 engages with the ring gear 8, so that the table 1 rotates with a predetermined speed. On the upper side of the support frame, frames 14 are placed along its outer diameter for mounting the forms 2, and the number of frames corresponds to the number of forms. The forms themselves are made of two parts: the bottom part 15 and the hinged cover 17 connected to it by means of a hinged connection 16 (Fig. 4). Form 2 is provided with coils on the entire surface of its surface. On the top of the cover 17, there is a serpentine 18, connected at one end to the central inlet pipe 19 and the other end with an outlet pipe 20 installed on the invisible side. On the lateral surface of the lower part 15 Another coil 21 is provided with its own inlet 22 and outlet 23 holes, and on the adjacent surface: the inner part 15 is a coil 24 with inlet 25 and outlet 26 holes. Forms 2 and their coils 18, 21 and 24 are filled in succession with steam for heating or cold water for cooling. Different types of working medium are introduced and discharged through the distribution head 27 located on the central axis of the table 27, which consists of a stationary lower part 28 with an inlet pipe 29 from the steam boiler rotating with the table top 30, from which the feed lines. Inside the distributor head 27, various types of working medium transfer from a stationary to a rotating system. The upper part 30 of the distributor head is surrounded by four annular conduits 31-34 located one above the other, which, through the radial connecting conduits 35-38, are connected to the distribution pipelines 39-42 located next to each other. . From these pipelines to the corresponding inlet and outlet ports of the coils on the forms are the corresponding connecting pipes 43-46. Each of the connecting pipelines has its own shut-off valve 47-50, respectively, each of which is regulated depending on time or on the position of the table. The cooling water preparation unit includes a condensate tank 51, a cooling water collector 52 connected via a connecting pipe 53, a cooler 54 connected by a connecting pipe 55 to a collector cooling water through a valve 56 and a pump 57 for increasing the pressure included in the pipeline in order to raise the pressure of the cooling water to the required level to cool the molds without evaporation and eliminate steam shocks. The spent cooling water returns to the cooling water collector through pipe 58, and a reducing valve 59 is provided in front of the cooling water collector. Cooling water enters the distributor head from refrigerator 54 through pipe 60. To ensure reliable shape closure, frame 14 is vertically movable during the whole foaming process plate 61, under which is an air cushion 62 created by compressed air. The installation operates as follows. After filling form 2 with foaming mixture at the loading position and closing the lid 17 with its additional pressing with an air cushion, when the table reaches the next position, valves 47 and 49 are opened to allow steam to enter and condensate to drain. Steam from the steam boiler through supply pipe 29, distribution; head, connecting pipe 38 to the surrounding distributive, pipeline 39, from where it goes through the connecting pipe 43 of separate forms into the inlet pipe 19 of the coil 18. From the coil 18, steam condensate through the exhaust 20, connecting 44, distribution 40, radial connecting 37 and The annular 33 piping is returned to the steam condensate collector 51, from where it returns to the system as a steam boiler (not shown). After reaching and maintaining the required temperature (after half a turn of form), valves 47 and 49 are closed, form cover 17 is opened, the product is removed, and valves 48 and 50 are opened so that cooling water flows through the coils and cools the form to a predetermined temperature. The cooling water from the refrigerator 54 through the connecting pipe 60 and the distribution head enters the ring pipe 32 and then through the radial connecting pipe 36 - into the distribution pipe 45 - into the same inlet pipe 19 of the coil 18, so that this causes the cooling
    [2]
    2. The heated cooling water leaves the coil 18 through the outlet 20, connecting 46, distribution 42 and radial connecting 35 pipelines and flows through the ring pipe 31 and pipe 58 into the cooling water collection 52, from where it is fed through pipe 55 and the pump 57 to increase the pressure the refrigerator 54c is intended for further use in the cooling water circulation system. In order to avoid corrosion in the coil of the molds, steam condensate is used as cooling water, for which steam condensate flows from tank 51 through conduit 53 to cooling water collection 52, from where it along with spent cooling water enters refrigerator 54 for further use. The use of the proposed plant allows to increase its service life and reliability of elements and to increase productivity. Claims An apparatus for manufacturing products from expandable polymeric materials comprising a rotary driving table with detachable forms located on it, connected through a system of connecting and distribution pipelines for supplying and discharging steam and cooling water to a distribution head located along the central axis of the table, characterized by so that, in order to increase the reliability of the installation and its performance, it is equipped with a connecting and distribution piping system node preparing rows of cooling water, configured as a container for the condensate collector and the cooling water condenser connected through a pump for pressurizing the cooling water with the collection.
