Description

Drying chamber

The utility model relates to equipment for drying wood primarily in the form of lumber or blanks.

For this purpose, various dehumidification chambers with

convective heating of the dried materials and forced recirculation of the soup agent in horizontal or vertical planes relative to the stack of lumber (Krechetov I.V. Drying of wood. M., Ed. Breeze, 1997, cip.244).

In the drying technique, the most progressive aerodynamic circuits of the drying agent circulation are chambers with a vftical ring of air movement relative to the stack of lumber. This is due to two circumstances:

1. The ability to create cameras with any volume of loading and transporting piles to both ends of the camera.

2. The ability to organize the movement of air flow along the shortest circulation ring with its lowest aerodynamic drag.

However, due to such inherent disadvantages as uneven air flow along the height and length of the stack, an increase in the height of the chamber due to the space behind the false ceiling, and the high cost of electric fan equipment for forced air circulation, they did not find wide application in domestic drying equipment.

A well-known timber chamber of Latgiprom containing a housing, a heat source, a recirculation fan with a snail, air ducts, a centrifugal fan. But such a model of the camera did not find SECURITY. The main reason for this was the significant non-uniformity of the flow of the soup agent in the stack (I.V. Krechetov. Wood drying. M., Izd. Briz, 1997, p. 222) - prototype.

The technical task of the utility model is to increase the uniformity of the distribution of the drying agent over the stack of lumber with a vertical circulation ring by creating an air duct with constant static pressure along its height in front of the side surface of the stack of sawn lumber and with direct induction of air movement by a centrifugal fan.

To increase the uniformity of the flow of the drying agent in the ogabel of sawn timber in a known chamber containing a housing, a heat source, a recirculating fan with a scroll, air ducts, a centrifugal fan or fans, is installed in the middle part on one side of the chamber, with its exhaust opening directed to the upper part of the chamber, and the surface of the shell of the cochlea, facing the stack, names the drying agent between the false ceiling and the ceiling of the chamber, and the fan motor is located outside the working volume. Near the walls of the chamber there are vertical E1fans that overlap the end zones of the stack.

Comparison of the claimed utility model with the prototype shows that it has the following features:

- a centrifugal fan or fans is installed in the middle part on one side of the chamber;

a strong agent between the false ceiling and the cell ceiling;

- the electric fan drive is located outside the working volume of the chamber.

Therefore, the claimed utility model meets the criterion of “Novelty.

The inventive utility model can be made using

well-known processes and equipment.

Therefore, it meets the criterion of Industrial applicability.

In Fig, 1 schematically shows a longitudinal section of the camera, and in Fig, 2 the camera in plan.

The camera contains a housing 1 in the middle part near one of the walls of which there is a centrifugal fan (fans) 2 with a cochlea. In front of the fan there is a kayaliferifer 3. In the upper part of the chamber there is a false ceiling 4. Vertical screens 5 overlap the end zones of the wall plug 6.

The operation of the camera is as follows.

The air flow is ejected by the fan 2 between the false ceiling 4 and the ceiling of the chamber and then enters the space along the side surface of the cable on the opposite side of the fan. At the same time, the air flow changes its direction by 180 degrees and the air enters the inter-row space of the stack 6. Passing along the gaskets, the flow enters the air heater 3 through its entire width, and then into the suction hole of fan 2, Vertical screens 5 overlap the end zones of the stack 6 and reduce the acgava zone of the circulating agent of the drying agent along the length of the lumber. In these areas, the speed of the drying agent is close to zero, which avoids the occurrence of microcracking.
