(54) METHOD FOR DRYING BURNERS IN STABLES AND CAMERA FOR ITS IMPLEMENTATION

t

 The invention relates to the drying technique, in particular to the drying of lumber, and can be used in wood processing.

Known cnocot & i drying lumber in piles placed in a drying chamber, by feeding pfzogret drying agent into the cavity of the chamber and.

Known methods of drying lumber are carried out in chambers containing a body with stacked lumber stacks, moisture condensers and heat-ventilating equipment 11.

A disadvantage of the known methods of drying lumber is a significant temperature difference across the cross section of the piles and, as a result, uneven drying of lumber.

 The closest to the invention in its technical nature is a method of drying lumber in piles placed in a drying chamber, by circulating the drying agent, then cooling it and condensing excess moisture. This drying method is carried out in chambers containing

a body with piles of lumber placed inside it, heaters, fans connected to the channels for supplying the drying agent, moisture condensers and reflective screens located on the front sides of the piles 2.

The disadvantage of this method

10 drying lumber and the camera for its implementation is the low quality and uneven drying of lumber.

The purpose of the invention is to search for ca. lumber drying qualities.

15

This goal is achieved by the fact that when drying lumber. in stacks arranged in the drying chamber, by circulating the drying ariBHta with its subsequent cooling,

20, the condensation of excess moisture is carried out in the upper part of the drying chamber above the piles and the condensate obtained sweeps the end surfaces of the sawn timber.

The proposed method of drying lumber is carried out in a drying chamber comprising a body with lumber piles inside, heaters, a fan and channels for supplying arsHia drying, moisture condensers and reflective screens located on the end sides of the piles, with capacitors placed above the piles and are supplied with moisture collectors, made in the form of trays with a longitudinal slit, under which the curtains closing ends of the stacks are made of heat-resistant and moisture-permeable material, advantageously ety steklotka audio, Figure 1 shows A proposed for lumber drying chamber; figure 2 is a cross section aa in figure 1; on fig.Z - section bb in fig, 2. The chamber for suyka sawnwood comprises a housing 1 in which stacks of 2 sawn timber are placed. In the interior, along the side walls of the housing 1, the heaters 3 are located. Above the piles 2 of the sawn timber there are condensators 4, made in the form of columns, in which cooling water circulates. For receiving condensed moisture, the capacitors are provided with collectors 5, made in the form of trays with a longitudinal slit, under which the curtains of the heat-resistant and moisture-conducting material are fixed at the ends of the stacks. In the chamber there is a fan 7, installed inside the pressure pot 8, located under the stacks in the horizontal plane a pargitel with suction channel 9. The side screens 10, the discharge channel 8 and the suction channel 9 serve for the directional movement of the drying agent from the heaters. They are connected to the cavity of the chamber with holes 11 and are provided with shutters 12 with a distributor mechanism 13. The camera operates as follows. In-case 1 load sha-abels of 2 pi materials. The drying agent, heated by heaters 3, is supplied by the fan 7 and guided by side screens 10 to the horizontal channels of the stack 2. After passing the head of the drying agent, they are heated by calorimeters 3 at the opposite side of the chamber. Then the drying agent is fed into the hole -11 suction channel. where it transmits the heat of the upper walls. | Ke suction 9 and nagGleatnogo 8 channels, and through them - the lower part of the stack. In the upper part of the chamber, the spent drying agent is cooled by condensers 4, in which curing water circulates. The condensed moisture enters the collections 5, then through the slit in the collections on the curtain 6 and moistens the end surfaces of the piles. . The directional circulation of the drying agent in the horizontal channels of the stacks is carried out by simultaneous feeding and suction through the slotted holes 11, which are alternately closed after 0.5-3.0 minutes, then at one or the other pile, the movable gate 20, which moves under the action of distribution mechanism 13. The application of the proposed method And the chamber for drying lumber in piles allows to increase the uniformity of the distribution of heat and moisture indicators of the drying agent throughout the volume of the pile, to improve the GUT material to be dried by eliminating drying stacks of end surfaces at more economical expenditure of thermal energy by the use for - moistening the ends vlygi condensed. claims 1. A method of drying lumber in piles placed in a drying chamber, by circulating the drying agent, then cooling it and condensing excess moisture, which means that, in order to improve the quality of drying, moisture condensation is carried out in the upper part of the drying The chambers above the piles and the condensate obtained will moisten the end surfaces of the pilots. 2.. A chamber for drying sawn timber in piles, comprising a body in which the saw-saw piles are located. materials, heaters, fan and channels for supplying the drying agent, moisture condensers and reflective screens located on the end sides of the stacks, which means that, in order to improve the quality of drying, the condensers are placed above the stacks and equipped with moisture collectors / in the form of trays with a longitudinal slit, the floor of which is fixed by the curtain ends of the stacks of heat-resistant and moisture-transmitting material, mainly fiberglass.
