Description

 The invention relates to drying equipment and can be used in the building materials industry for drying ceramic products of bricks, tiles, etc.

 A well-known industrial building for drying ceramic products, including walls with side shields, floor, roof, forming a drying chamber (Bakhmutsky KM Brick production in small factories. Sverdlovsk, 1961, p. 40).

 The disadvantage of this building is its low productivity due to the long cycle of the drying of clay bricks.

 As a prototype, an industrial building for drying ceramic products, including walls with side shields, a floor, a roof with a ridge, forming a drying chamber with fans, and a technical underground (Bakhmutsky K.M. Brick production in small plants. Sverdlovsk, 1961, p. .40-43).

 The disadvantage of this building is the insufficiently high quality of dried ceramic products due to the lack of uniform recirculation of heated atmospheric air.

 Another disadvantage of this building is the low drying capacity due to the insufficiently high degree of mechanization of loading and unloading in the drying chamber, and also due to the uneven drying of clay bricks along the length and width of the drying chamber, which lengthens the drying cycle.

 In addition, in this building it is impossible to dry clay bricks under various weather conditions at all times of the year, which reduces its technological capabilities.

 The problem solved by this invention is to improve the quality of the semi-finished products, the drying process productivity and expanding the technological capabilities of the industrial building by ensuring uniform air recirculation both along and across the drying chamber.

 This is achieved by the fact that the industrial building for drying ceramic products is equipped with hoisting and conveying equipment with crane tracks, recirculation ducts with slots, and coolant ducts located in the technical underground, the floor has ducts for the coolant, and the fans are located on the conveyor equipment at the ridge of the roof and connected to air ducts for air recirculation.

 A comparison of the claimed invention with analogues identified in the analysis of the prior art, allowed us to establish compliance with its criterion of "Novelty."

 The set of essential features of the claimed invention should not be obvious to a specialist from the prior art, which allows us to conclude that it meets the criterion of "Inventive step".

 Due to the fact that the proposed device is intended for use in the building materials industry, and when it is used, the above technical result can be achieved, the claimed invention meets the criterion of "Industrial applicability".

 The drawing shows a device for drying ceramic products.

 The device includes walls 1, of which the sides have shields 2, and end doors 3, and floor 4, roof 5, forming a drying chamber 6, which has two fans 7, as well as a technical underground 8.

 In order to solve the problem, the industrial building is equipped with lifting and handling equipment made in the form of a "gantry" crane 9, moving on crane tracks 10 and having a load gripping mechanism 11, as well as air ducts 12 for air recirculation and air ducts 13, 14, respectively, for supply and selection coolant. Ducts 13 for supplying coolant are located in the technical underground 8 near the side walls 1, and duct 14 for taking coolant is located in the central part of the technical underground 8. Fans 7, ducts 12 (right and left) are located on the gantry valve 9 and are interconnected . Slots 15 are made in the air ducts 12 for air recirculation, and in the floor 4 of the building there are channels 16 for supplying and withdrawing coolant connected to the air ducts 13, 14. Fans 7 are located in the ridge 17 of the industrial building.

 Drying of ceramic products, such as clay brick packages 18, in the proposed industrial building is as follows.

 Clay brick to be dried, laid in bags 18, through door 3 using trolleys (not shown) and a load-gripping mechanism 11 of the gantry crane 9 is placed in the drying chamber 6 of the industrial building.

 During natural drying, the shields 2, doors 3 are open. Atmospheric air enters the drying chamber 6, passes through brick packages 18, while warm air rushes into the ridge zone 17 of the industrial building. A new portion of atmospheric air is mixed into the air that has passed through these zones, which then leaves through open panels 2 and doors 3.

 In the artificial drying mode, the shields 2 and the doors 3 of the drying chamber 6 are closed. Heat carrier heated air is supplied to the cavity of the air ducts 13 located near the side walls 1, and through the channels 16 of the floor 4 it enters the drying chamber 6, rushing into the ridge zone 17, as well as into the heat transfer duct 14.

 In both natural and artificial or mixed drying, warm air in the area of the ridge 17 is sucked in by the fans 7 and through the slots 15 of the air ducts 12 is sent to the clay brick packages 18, thereby recirculating the air across the drying chamber 6. Moving the gantry crane 9 s installed on it by fans 17, recirculate air along the drying chamber 6.

 After the drying process is completed by means of the load-gripping mechanism 11 of the "gantry" crane 9, the clay brick packages 18 are mounted on trolleys and transferred to kilns.

 Due to the fact that the industrial building is equipped with lifting and handling equipment, made in the form of a "gantry" crane 9, which has six support racks and a load gripping mechanism 11, mechanization of labor-intensive loading and unloading operations is provided.

 Placing fans 7 near the ridge zone 17 and air ducts 12 having slots 15 on the “gantry” valve 9 allows air recirculation both along and across the drying chamber 6, as a result of which the drying process of clay bricks is accelerated and their drying uniformity increases, which improves productivity and drying quality.

 Placing in the technical underground 8 air ducts 13, 14 for supplying and withdrawing coolant and connecting them to channels 16 made in floor 4 allows the drying process to be carried out regardless of weather conditions and the season, which expands the technological capabilities of an industrial building.

 Thus, the use of the present invention allows for year-round drying of ceramic products, the quality is not inferior to natural drying, and in terms of productivity approaching artificial drying with a significant reduction in energy costs for the drying process.
