RU2454324C2 - Curing room - Google Patents

Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to construction and may be used for curing concrete articles. Proposed curing room comprises walls with inner flange, hydraulic gate frame mounted on wall edges, shield with inner surface provided with steam-and-water insulation coating and heat insulation, steam duct, and condensate drain chute. Hydraulic gate frame is made up of horizontal channels arranged horizontally along room walls to house elastic porous material for room sealing by absorbing condensed steam. Aforesaid shield is made up of carcass consisting of weight-reduced channels coated by heat-insulation material with inner cavities. Said shield serves to press elastic porous material against all edges of channel cavity.

EFFECT: high-reliability sealing.

Description

The invention relates to the field of construction and can be used for steaming concrete products.

Known autoclave, consisting of a housing, two covers with lifting mechanisms and two bayonet rings with rotation mechanisms, movable bearings, fixed bearings, pump station with a hydraulic and electrical control system [1].

Its disadvantages are the complexity and cumbersome design, heavy weight, the need to cool the rubber gasket from overheating, which leads to its destruction and the need to spend additional resources.

The closest in technical essence and the achieved technical effect is a pit steaming chamber containing walls made with an inner rim, a water lock frame mounted on the walls around the perimeter, a screen in the form of vertically mounted along the chamber perimeter and interconnected trough-like plates, the inner surface of which has vapor-waterproofing coating and thermal insulation [2].

Of all the above analogues, the closest in technical essence and the achieved technical effect is a steaming chamber of the pit type [2].

The disadvantage of this pit-type steaming chamber is that the frame is laid directly on the sides, which does not ensure the tightness of the screen when it is deformed and requires high precision manufacturing of both the screen and the sides.

The above disadvantages can be eliminated if the chamber is sealed.

The problem is achieved in that in a known steaming chamber, including walls made with an inner rim, a water seal frame mounted on the walls around the perimeter, a screen, the inner surface of which is made with a steam-waterproof coating and heat insulation, a steam pipe, a groove for condensate drain, a water seal frame from channels placed horizontally along the chamber walls, into the cavity of which elastic porous material is laid to a height exceeding the height of the channels to seal the chamber due to absorbing condensed steam into an elastic porous material, and the screen is made in the form of a frame of a lightweight profile coated with a heat-insulating material having internal cavities, while the screen is mounted with the possibility of pressing the porous material along the entire contour of the channel cavity.

Another difference is that the porous elastic material is made of foam rubber, and the screen is made of a lightweight rectangular profile, covered on the outside with heat-insulating material made of lightweight polycarbonate, with closed longitudinal internal cavities.

The use of a steam-waterproofing coating is necessary to reduce the share of thermal energy consumption for heating the enclosing structure of the chamber.

The implementation of the walls with the inner side ensures the tightness of the steaming chamber.

The use of cellular polycarbonate significantly saves energy, the air contained in the space between the stiffeners inside the panels is an excellent heat insulator and can save up to 50% of energy. Lightweight polycarbonate panels withstand temperatures from -50 to + 120 ° C. Also, this material has high strength [3].

An additional search of scientific and technical literature showed that the set of essential features given in the invention is unknown, therefore, the technical solution has novelty.

The given set of features does not follow explicitly from the modern engineering level, therefore, it has an inventive step. The proposed technical solution is tested in production, therefore, it is industrially applicable. Thus, the proposed technical solution meets the eligibility criteria.

The steaming chamber is illustrated by drawings, where Fig. 1 is a schematic sectional view of a steaming chamber, Fig. 2 is a diagram of a water seal, Fig. 3 is a diagram of a water seal with a closed lid, and Fig. 4 is a schematic view from above of a steaming chamber , and figure 5 shows the frame of the screen and a rectangular profile, and figure 6 is a device for vapor barrier.

The steaming chamber consists of walls - 1, made with inner sides - 2, mounted on the walls along the perimeter, screen - 3, water seal - 4, consisting of channel - 5, laid horizontally along its walls - 1, into the formed grooves of which elastic porous is laid material (foam rubber) - 6 to a height exceeding the height of the channel element, while the screen - 3 is made in the form of a frame - 7 with a rectangular profile - 8, covered with heat-insulating material - 9 with internal cavities - 10, vapor barrier -11. A steam line was conducted to the tank - 12. The bottom is equipped with a groove - 13 for condensate drain.

The steaming chamber works as follows: concrete products are loaded into the steaming chamber, and then a screen - 3 is laid, which presses elastic porous material (foam) - 6 around the entire contour, creating a seal. Steam is supplied through the steam line from the steam generator, which, while warming up the product, partially condenses on the screen surface - 3, moisture, draining, is absorbed into the elastic porous material (foam rubber) - 6, cooling, it seals the inner space. The rest of the condensate flows down the walls - 1 into the groove - 13. At the end of the steaming of the concrete products, the steam supply stops, after cooling the product is removed from the steaming chamber.

The use of the proposed technical solution allows, in comparison with the prototype, to achieve a technical effect - reliable sealing of the camera, a significant reduction in screen weight.
