RU41848U1 - DRYING CHAMBER - Google Patents

Abstract

The utility model relates to the field of building materials and can be used in the technology of woodworking and wood drying. The drying chamber includes a thermally insulated body, a reversible-jet air circulation system with a blower fan, an air heating system and moisture condensation; the side walls of the chamber are provided with calibrated holes. It differs in that the calibrated openings are located in the lower part of the chamber to the level 1 / 6-1 / 8 of the height of its side walls from above, and moisture condensers - in the upper part of the chamber equidistant from its walls. Due to the proposed structural design of the drying chamber, an increase in profitability, acceleration of the drying process of wood is provided, and a decrease in the drying temperature allows the use of a drying chamber for drying vegetables and fruits.

Description

The utility model relates to the field of building materials and can be used in the technology of woodworking and wood drying.

Known drying chamber (Japan patent No. 6100423 B4 from 12.12.94, 5 F 26 In 21/04, publ. Bull. No. 6, 1998), consisting of a sealed chamber, as well as a system of pressure and air intake.

However, due to the significant cost of the coolant, it is not possible to dry and efficiently dry wood.

Also known is a drying chamber (certificate. No. 20956 U1 dated 05/29/2001, 7 F 26 В 21/02, publ. Bull. No. 34, 2001 - prototype), which includes a heat-insulated casing, a reversible-jet air circulation system with a blower fan, a system for heating air and moisture condensation, and in which the side walls of the chamber are provided with calibrated holes and the moisture condensers are equipped in the side air ducts.

The disadvantages of the prototype are the long drying cycle of wood due to the location of moisture condensers in the ducts and lack of efficiency, since the calibrated holes are located over the entire area of the side walls of the chamber, which requires the use of a powerful fan to create a uniform reverse circulation of the heated air.

The technical problem to which the utility model is aimed is to accelerate the drying of wood, increase efficiency, expand the scope.

The technical problem is solved as follows. In a drying chamber including a thermally insulated body, a reversible-jet air circulation system with a blower fan, an air heating and moisture condensation system, and in which the side walls of the chamber are provided

calibrated holes, calibrated holes are located in the lower part of the chamber to the level 1 / 6-1 / 8 of the height of its side walls from above, and moisture condensers - in the upper part of the chamber equidistant from its walls.

Due to such a design of the drying chamber, the duration of the drying cycle of the wood is reduced, the drying temperature is reduced, the power of the used blower is reduced, which increases economy, accelerates the drying of wood, and the decrease in the drying temperature allows the use of the drying chamber for drying fruits and vegetables.

The process of drying wood in such a drying chamber occurs due to the uniform reverse circulation of heated air throughout the surface of the loaded stack, which is ensured by the passage of air through calibrated openings in the walls of the chamber located in the lower part of the chamber to a level of 1 / 6-1 / 8 of the height of its side walls from above, creating the same thermophysical conditions for all surface sections of the dried billets.

The utility model is illustrated in the figure. In FIG. depicts a drying chamber in plan with a schematic illustration of equipment.

The drying chamber consists of a thermally insulated housing 1, equipped with a blower fan 2, a purge cooler with oil heating 3, air ducts 4 with calibrated openings inside the chamber, moisture condensers 5, and doors with a seal 6.

The drying chamber operates as follows. The wood blanks formed in stacks are loaded into a drying chamber. Then turn on the blower fan 2 and heat the purge radiator with oil heating 3. The uniformity of wood drying is ensured by uniformly blowing the entire stack section through calibrated openings. Moisture condensers 5 maintain the necessary humidity, To improve the drying mode, moisture condensers are located in the upper

parts of the chamber equidistant from its walls and symmetrical to each other, for example as shown in FIG. their amount is selected depending on the moisture content of the feedstock and the required humidity after drying. Raising and maintaining the temperature regime of drying is achieved by an electric circuit for heating transformer oil and heat extraction from purge radiators. The heating process takes place automatically. The operation of the drying chamber is controlled by a standard automatic station, which provides a reverse mode of operation of the discharge fan and control of temperature and humidity.
