Description

 The invention relates to a drying technique and can be used in the building materials industry for drying ceramic bricks and ceramic tiles.

A known installation for drying products containing a drying chamber with vertical partitions forming a zigzag channel in which a vertically closed conveyor with pendants for products and air distribution boxes is placed [1]
Also known is a sectional conveyor dryer SMK-216, taken as a prototype, containing sectional drying chambers, a vertically closed conveyor with hangers for products and air distribution ducts [2]
The disadvantages of the known devices are long drying times due to the lack of devices for creating and regulating a vapor-air environment.

 The aim of the invention is to accelerate drying and improve product quality.

 This goal is achieved by the fact that in the installation for drying products containing a drying chamber with vertical partitions forming a zigzag channel in which a vertically closed conveyor with pendants for products and air distribution boxes is placed, pallets with water and heaters are installed under the lower branches of the conveyor to create steam media and air distribution ducts with air heaters, and openings with regulators for venting air are made over the upper branches of the conveyor in the side walls s installation.

 In FIG. 1 shows the proposed installation, a longitudinal section; in FIG. 2 same cross section.

 The apparatus for drying products contains a drying chamber 1, vertical partitions 2, dividing it into sections, above which there is a horizontal partition 3, a vertically closed conveyor 4 with perforated suspensions 5 for products 6, air distribution boxes 7. Under the lower branches of the conveyor 4 and boxes 7 are installed pallets 8 with water and heaters 9. In the boxes 7 at the inlet openings 10, heaters 11 are installed. Above the upper branches of the conveyor 4, holes 12 are made in the side walls for venting air from the installation. Before the holes 12, air flow regulators 13 are installed. To move the conveyor 4 in the upper part of the chamber mounted hydraulic cylinders 14, pivotally connected with levers 15, mounted using an overrunning clutch on the shaft 16 of the conveyor. To tighten the chains of the conveyor 4, tensioning devices 17 are installed on the lower branches of the conveyor 17. A loading hole 18 is made in the end wall of the drying chamber 1. Rails 19 are mounted on the drying chamber 1, on which a carrier 20 of the layer with a group gripper 21 is mounted for removing products 6 from suspensions 5 and their further movement into the kiln.

 Installation for drying products operates as follows.

 Products 6 coming from the press are stacked in a predetermined position by the stacker on perforated suspensions 5 mounted opposite the loading hole 18. With hydraulic cylinders 14, through the levers 15, the conveyor moves one step of the suspensions, after which the next suspension is loaded with products. In each section of the drying chamber 1, its own temperature and humidity regime is created. To do this, the heaters 9, the water in the pallets 8 is heated to a predetermined temperature to ensure vaporization, and the air entering through the openings 10 into the air distribution boxes 7 is also heated by the heaters 11 to a predetermined temperature. The vapor-air mixture formed in the dryer through the openings 12 with the regulators 13 is discharged into the duct system with a vacuum fan. In boxes 7, incoming air is evenly distributed over the entire area of each section. Due to convection, the air-vapor mixture in each section rises up, while the entire temperature of the section provides the specified temperature and humidity conditions for all products in the section. The steam-air mixture is discharged separately from each section through the openings 12 with the regulators 13. The flow of the steam-air mixture discharged from each section is set by the regulators 13. The conveyor 4 of the product 6 moves in a zigzag manner through all sections of the drying chamber, in each of which they are dried according to their predetermined temperature humid conditions and dried up to the specified parameters are moved to the upper horizontal branch for unloading. By group capture 21 of the carrier 20, the layers of the product 6 are captured from the suspensions, rise up above the drying chamber, after which the carrier 20 of the layer, rolling along the rails 19, transfers the products to be loaded into the kiln.

 The inventive installation for drying products by creating a vapor-air medium with predetermined parameters in each section and moving products through sections allows you to provide the specified mode, speed up the drying of products and improve their quality.
