Abstract

An aerodynamic dryer containing a chamber with a door in its end wall, a centrifugal fan rotor oriented along the longitudinal wall of the chamber, dividing and guiding screens, a humidification device, characterized in that the chamber is made through and is equipped with a second door located in the end wall of the chamber opposite the first door while the separation screen is rotatable, and the guide screen is in the form of a parabola and the latter is installed between the fan rotor and the second door, and its straight sections are in executed by mobile.

Description

AERODYNAMIC DRYER.

The utility model relates to a technique for drying materials, namely wood.

Known aerodynamic dryer containing a chamber with a door in its end wall, a rotor of a centrifugal fan, oriented along the longitudinal wall of the chamber, dividing and guiding screens, humidification device (AS No. 436217 F26B9 / 06, publ. 1974).

This technical solution is the closest to the proposed utility model.

A disadvantage of the known device is the limited technological capabilities. The purpose of the utility model is to expand technological capabilities.

This goal is achieved by the fact that the camera is made through and equipped with a second door located in the end wall of the camera opposite the first door, while the separation screen is rotatable, and the guide screen is in the form of a parabola and the latter is installed between the fan rotor and the second door, and its direct the plots are movable.

In the drawing of Fig. 1, a general view of an aerodynamic dryer is given, in Fig. 2 is a section AA in Fig. 1.

The aerodynamic dryer contains a heat-insulated passage chamber 1 with a door 2 and a door 3 with seals, a centrifugal fan rotor 4, a rotary separation screen 5, a parabola-shaped guide screen 6, the straight sections 7, 8 of which are made movable, a humidification device 9, a pressure channel 10.

Aerodynamic dryer operates as follows. Through one of the doors 2 or 3, the stack is loaded into the chamber 1, while in the case of loading through the door 3, divide 9-o in e / o / 02, e9 s-6 /

The body screen 5 rotates on the axis and frees up the passage for the stack. After the stack is installed in the chamber 1, the doors are closed and the rotor 4 of the centrifugal fan is turned on, as a result, the agent is sucked from the interstitial gap into the volume between the door 3 and the dividing rotary screen 5 and then the drying agent is pumped into the pressure channel 10 formed by the chamber wall 1 and the stack. Thanks to the guide screen 6, made in the form of a parabola, a uniform supply of the drying agent is achieved over the entire height of the stack. To remove waterlogged air from the chamber 1 and supply fresh, there are nozzles (not shown in the drawing) having an adjustable flow area. Humidity control is carried out using the built-in psychrometer. To humidify the air at the end of the drying process, the supply of hot water through the humidifier 9 is provided. After the drying process is completed, the stack is unloaded from the chamber 1.
