Description

Drying Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus, and more particularly, to an apparatus for drying a wood semi-finished product such as wood, veneer, or wood or other product cut by a saw.

Small trees, such as perennial trees, contain a relatively large amount of moisture, depending on the type after they are cut. As is known, wood contains capillaries in cells, which contain free liquid and absorbed water molecules called water content, which must be lowered to a certain level in order to meet industrial requirements. For this reason, wood should be dried to an acceptable final moisture distribution in order to prevent the occurrence of defects due to proper treatment, for example drying. This drying process is an important factor from an economic point of view.

Wood can be dried in an open natural environment if the climate conditions associated with the wood are quite good and a suitable quality dried wood can be produced (air drying). It should be taken into account that air drying wood is a long process that can take several years. Finally, the drying of wood requires proper storage conditions, where the warm drying air circulates naturally and includes different design conditions. It is to be taken into account that water absorbed in wood can only be evaporated by ambient airflow if its surface is not covered by rain, snow or other material. Reloading to be ventilated only helps a little in the air drying method, and the drying is uneven, which may degrade the quality of the wood and may continue to be damaged by fungi, microorganisms, fungi and insects. There may always be unpredictable drying conditions that can be prevented by any preconditioning or monitoring method, namely shape deformation problems that may arise due to natural air. Moisture distribution in wood is dependent on the method of drying with air after a certain period of time depending on climatic conditions, which means that there is a time variable in design due to higher costs and higher quality failures. On the other hand, this technology also affects low energy consumption, large dry areas, storage and safety measures. Experiments to reduce air, that is, drying method using an axial fan, were also performed, but there are many variables such as relative humidity that the axial fan cannot control.

In order to reduce drying time in terms of cost, quality and time, different types of drying equipment have been developed which can be distinguished by technical attempts in the following manner. The first type is the lossless dryer (compartment kiln type) and tunnel type dryer (tunnel kiln type). These known drying apparatuses can be characterized by a stationary type. According to the first type of drying apparatus, wood is disposed in a compartment capable of generating different physical conditions such as temperature, humidity, airflow capacity, etc. in order to proceed with the drying treatment. According to the drying apparatus of the second type, the wood is conveyed through the drying apparatus by a horizontal transport unit, which is processed continuously under various physical conditions mainly to gradually carry out the drying treatment. The drying device of the lost dryer is cheaper than the drying device of the tunnel dryer, but the investment cost is relatively high due to the low production speed.

Known types of drying units have several drawbacks, such as the high investment costs and difficulty of installation, in terms of the economics described later.

Nowadays, technical treatments used to dry wood are a means of obtaining processing temperatures, for example, by oil, convection, conduction or radiation principles, such as low temperatures of 15-45 ° C, intermediate temperatures of 45-90 ° C or 90-130 ° C. It is carried out at high temperatures.

According to some types of drying equipment, the wood is placed in a compartment by a suitable transport carriage. Ventilation fans placed on the ceiling or elsewhere generate air flows which in some cases are blown in the transverse direction, in others they are guided in the horizontal and transverse directions and in other examples the air is guided in the longitudinal direction.

According to all of these known dryers, the transport is constructed in such a way and size that it can load as much wood as possible in the kiln volume. The wood is loaded along the ventilator in such a way that the airflow is in at least one horizontal plane. Specific compromises should be obtained, taking into account the size of air gaps required for airflow and timber in the kiln. When hot air comes into contact with wood containing high moisture content, the air absorbs moisture to the maximum possible, allowing it to absorb moisture deep within the loaded timber. The ventilation fan thus creates a sufficiently strong airflow with the maximum possible amount of water, which means that a lot of energy is consumed. Due to the high moisture content in the air, it is easy to cause damage by condensation in cold places such as walls and other equipment. Condensate that remains in the kiln volume has a detrimental effect on kiln volume and drying treatment.

As mentioned in patent application EP 0 170 648 AI, which implements one of the recent drying methods, the compartment has a warm insulating wall. The sawed wood is loaded into the kiln volume for longitudinal ventilation. The drying apparatus is provided with a ventilation fan for passing the airflow through the heating zone, passing the loaded wood to the cooling zone, and guiding the same airflow loop in this cooling zone. After the air is heated in the heating zone, it takes moisture as it passes through the loading timber, which is then released as it goes through the cooling zone to the heating zone. This combination is easy to make condensate when dealing with freshly cut wood, but is well suited for wood with low moisture content, ie finished wood, before being used industrially.

Air must be heated to release as much moisture from the compartment as possible from the saturated air generated by drying the loaded wood. In order to dispose of a large amount of saturated air, there is a lot of heat loss before using it as heated air. This wood drying method is low in energy efficiency.

In addition to the drying methods described above, vacuum drying methods are described in PCT / DK87 / 00012 and WO 87/04779, where the strength of the drying method can be monitored, for example, to avoid defects in drying. The apparatus employing the vacuum method is very sensitive to maintaining proper vacuum conditions and is more suitable for drying wood with less moisture, so other drying methods should be used to remove most of the moisture.

According to the above known means, these methods all have some imperfect aspects, for example, relatively low energy efficiency, unsuitable for the world economy, high requirements for space consumption, high dependence on power sources, high dry defect potential, very small It is made as a fixed type with a dry capacity which determines the quantity and method of dry wood.

According to the present invention, the drying apparatus is provided with a ventilation housing, the inner region of which is connected to the surrounding region by an exhaust pipe and a vent pipe. Therefore, according to the principles of the present invention, a new drying device is made based on a number of ventilation systems having various air intakes and air disposal means fixed to the drying device. Such a device comprises a heating condensation device comprising a heating part, a condensation part and a ventilation fan. This drying apparatus has a drying kiln on which the wood to be dried is placed with the aid of a transport carriage. The drying treatment is carried out in a drying kiln by forced circulating air. At least one wall of the kiln compartment comprises a system ventilating unit having a function of pre-orienting air at any time during the drying process in accordance with an air deflection plate placed on a loading space integrated in the kiln compartment by the heating condensation unit. An integral part of the chamber is provided with suitable vents for venting and venting, the heating condensing end being at the bottom of the kiln compartment from the opposite side of the drying compartment. The air deflection plate by the heat condenser has at least one vent, which can be a self-regulating integral part consisting of the partition wall and the top of the kiln volume, which is a tunnel in which the ventilation system is located in common with the top of the kiln compartment. Provide type vents. The whole part mentioned above is called air deflection plate. The vent described above begins at a microclimate vent mounted on top of the kiln compartment and is then mainly guided along the sidewall and ends in the kiln volume space.

In the kiln volume there is arranged at least one vent which can be angled by positioning in the on or off state. When the microclimate exhaust section is connected to the vent hole and closed, internal circulation occurs from the top of the kiln compartment and extends through the kiln volume.In the open state, the internal circulation air contacts the outside atmosphere again with the help of the ventilator. Parallel airflow of humid air into the atmosphere is taken out and absorbed into the fresh dry air in the tunnel-type vent due to the pressure difference. It is advisable to install heating elements in the tunnel vents.

According to the present invention there is provided a loading portion for loading the wood or other products to be dried is provided with accessories to enable vertical and horizontal stacking and longitudinal ventilation. This accessory can also position the main face of the dry wood vertically. Remote holders that enable the loading of wood are arranged perpendicular to each other and are shorter than the vertical supports of the stack. The stacking portions may be mounted stacked on each other. The bottom carriage may have a transport wheel. According to the present solution, an ultraviolet radiator for emitting ultraviolet rays to moisture contained in the air is disposed in the kiln compartment space close to the microclimate ventilator to eliminate the possibility of growth of molds, fungi and other microorganisms.

According to the principles of the present invention there is provided a new drying apparatus having a magnet assembled in a bipolar arrangement in a kiln compartment, the magnetization of which affects all treatments, ie chemical, physical and biological treatments.

According to the invention the drying apparatus also comprises a heating condensing apparatus having a ventilation fan assembled in the opening of the partition wall. This heat condenser is designed to connect irregular intermediate airflows to improve the condensation effect and heat dissipation.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

The drying apparatus shown in Figs. 1 to 3 is made of wood and the like having a kiln compartment (1) configured to satisfy the standards and other requirements known in the field of transport using standard containers for all known transport purposes. Designed to dry the material. The kiln compartment 1 has several advantages and some limitations compared to all currently known drying apparatuses, but this limitation can be overcome by the solution according to the invention. In this way the user can, for example, install the device very quickly and simply in a suitable position to use the drying device as a stationary or movable device.

At least one of the sidewalls 11, 12, 13, 14 of the kiln compartment 1, ie in this embodiment the longitudinal wall 13, is for example allowed to enter the kiln compartment 1 and to be accessed by a person, for example. An appropriate door 131 is provided. On the other hand, in the illustrated embodiment, the vertical wall 11 has a lifting door, which in this example is at least one fixed system ventilator 111, which in another way is the vertical wall 11. It should be placed at the site of. Hereinafter, the role of the system ventilation unit 111 according to the general idea of the present invention will be described in more detail as follows.

Opposite side of the kiln compartment 1, ie the upper part of the wall 12, is provided with appropriate exhaust funnels 1210 and 1220 of vent holes 121 and 122, respectively, for exhausting the interior of the kiln compartment to the outside atmosphere. An appropriate microclimate ventilation unit 1211 is fixed. By the micro-climate ventilation unit 1211, the vent hole 121 connects or disconnects the outer zone and the inner zone 10 'near the upper plate 100 of the kiln compartment 1, and the vent hole 122 is similarly In the same way, the appropriate microclimate ventilation section 1221 connects the interior atmosphere 10 " near the bottom 101 of the kiln compartment 1 with the outside atmosphere at a distance from the rear wall 12, A heating condensation device 2 is also located on the rear wall 2. By using the micro-climate ventilation unit 1211, a great advantage is obtained when the drying program is performed in an automatic manner.

The heating condenser 2 is schematically shown in FIG. 8 and has a housing 20, a condenser 21, a heater 22, and a compressor 23 having the following part, namely an outlet for condensation 201. And a throttle, which, together with the condenser 21, the heater 22, and the ventilation fan 25, are connected to an appropriate circuit 26 and the ventilation fan 25 is directed towards the other interior zone of the kiln compartment 1. Air continues to flow from the condensation part 21 to the heating part 22 in the same direction. This heating condensation apparatus 2 allows the warm humid air to reduce the amount of water formed as the condensate flowing out through the drain pipe 201 with the help of the condensation unit 21. The air warms in the heating section 22 by approximately 2 ° C. relative to the temperature of the air entering the kiln from the surrounding zone.

The kiln compartment 1 has a partition having an air deflection plate 3 proximate the heating condensation unit 2 at a predetermined distance from the side wall 12 connected to the bottom 101 of the kiln compartment 1 at the top of the kiln volume. The wall is assembled. The vents 121, 122 and the heating condensation device 2 are arranged between the side wall 12 and the upper region 100, and the air deflection plate 3 has a constant distance from the upper region 100 of the kiln compartment 1. Located below the upper zone 100 and extends toward the door 11 with the system vent 111 of the kiln compartment 1. In the upper region 100 having the air deflection plate 3, the vent 111 of the kiln compartment 1 blocks the passage 30 between the top 100, the side wall 112, and the air deflection plate 3. Position relative to the top 100 and the door 11.

Due to the shape and position of the air deflection plate 3 located at the bottom of the upper region 100, a tunnel-shaped vent hole 1000 is formed, which is installed in the vent hole close to the vent holes 121 and 122. There is a ventilation section 40 consisting of two ventilation fans 41, 42 spaced apart from each other, with two other ventilation fans 43, 44 also having a heating element 430, 440. It may be disposed in the middle of the).

The loading door 11 is located in the space between the bottom 101 of the upper and air deflection plates 3 and the system ventilation section 111 and the wall, respectively, and the remaining kiln volume 6 provides a sufficiently large kiln volume. To carry at least one or more carriages with a stacking portion 5 on which the wood or other material to be dried is stacked. Hereinafter, all the details regarding the loading part 5 according to the principle of the present invention will be described.

In the drying apparatus there is also provided at least one ventilation section 7 consisting of at least one ventilation fan 71 which distributes the flow of air. In position, the ventilation fan is inactive when disposed parallel to the adjacent side wall of the kiln compartment 1 and is active when it is pivoting in reverse. The ventilation fan should be swiveled when inactive, for example when the carriage 5 moves along the kiln volume 6 for some reason. The two ventilating fans 71 ', 71 "shown in FIG. 3 are arranged separately on appropriate supports 72', 72", each support of the longitudinal side walls 13, 14 of the kiln compartment 1; Located on one side.

The wooden carriage loading part 5 as shown in FIG. 9 has a wheel and is placed in the kiln volume 6. The carriage loading section 5 allows the vertical stacking elements 52 to be stacked in a vertical state by means of the vertical remote element 51 and at the same time allows the vertical loading section 52 to be loaded to a certain extent over the entire width. It consists of. The at least one stack 5 has the wheel 50 of FIG. 4 and may have more stacks. In this manner, the separate stacking portions 5 having the wheels 50 can be mounted to each other at a desired height. Thus, as shown in FIG. 5 and FIG. 7, it can be loaded to desired extent in the vertical and horizontal direction with respect to the whole kiln volume 6, and air can be vented well.

According to the invention it is best suited to choose to load wood in the kiln volume 6 on the stack 5 in such a way that the main surface of the wood is arranged on a vertical plane. The timber sections having a small width need to be stacked in the stacking section 5 by stacking them vertically to create an air gap between the timbers by means of suitable remote elements 51 '.

In addition, according to the present invention, the ultraviolet radiation device 8 is mounted in the kiln compartment 1, more precisely in the zone 10 ', which is preferably an ultraviolet emitter, and includes fungi, fungi and other microorganisms. In order to eliminate the possibility of strains of the ultraviolet radiation to the moisture contained in the air.

It is also possible to use at least two magnets 9 arranged bipolar in the kiln compartment 1 in zone 10 ', which magnetization affects all processes, ie chemical, physical and biological treatments. It affects the properties of all moisture present in volume (1).

According to the present invention, the drying apparatus of FIGS. 4 and 5 provides a drying method which dehumidifies by the condensation-convection method in the manner as described above. The timber to be dried is opened by lifting the lifting door 11 on the loading section 5 where the timber is properly stacked by an accessory 51 which may have a vertical remote element 51 'and a horizontal remote element 52 as necessary. It is placed in the kiln volume (6). At this stage a thin layer of wet material attached to the rough side of the sawn cut wood is provided to the wood to prevent further loss of moisture from the wood. After the wood is put into the kiln volume 6 and the door 11 is closed, the ventilation fans 41, 42, 43, 44, the ventilation part 40, the ventilation fan 25 and the ventilation fan attached to the heating condensation part ( Operation 71) starts the drying process. The system ventilation unit 111 and the door 11 assembled to the wall are closed. The heating condensation unit 2 is operated so that air circulates at a predetermined temperature value obtained by operating the heating elements 430 and 440 of the ventilation unit 40. If this state matches that desired, the heating elements 430 and 440 are stopped and the desired heat can be supplied only by the heating condensing device 2 in the operating state. Appropriately heated air must be properly circulated to accelerate the drying process. When the water present in the wood / in water is absorbed by the air, it passes through the heating condenser 2, and the water is removed by the drain pipe 201 after the moisture is removed with the help of the condensation unit 21 shown in FIG. It is withdrawn from the heat condenser. In this step, the kiln compartment 1 may be connected to the outside air by the vent holes 121 and 122. When the air passes through the heat condenser 2, the air is heated to a certain temperature and absorbed by the ventilation fans 25, 41, 42, 43, 44 during the circulation movement through the tunnel-type vent hole 1000. The pores are heated by appropriate heating elements 430 and 440 as necessary and then pass through passage 30 and into the kiln volume 6 by means of the system vent 111 and air deflection plate 3 where the carriage It is guided by the ventilation fan 17 according to the arrangement of the wood stacked on the stack 50.

By this dry state, moisture can be strongly transferred from the wood into the purified air. Through the air vent 122, the air exits from the kiln volume 6 and the kiln compartment 1 to the outside atmosphere. As can be seen scientifically, the moisture-rich cooling air tends to descend to the downstream side, in this case down to the bottom 101 of the kiln compartment 1. However, since the pressure difference occurs at the same time, the air released through the vent hole is replaced by fresh air containing less moisture through the vent hole 12 by the micro climate vent unit 1211.

The remainder of the available air in the kiln volume 6 passes through the heating condensation unit 2, releasing moisture from the air by the condensation unit 21 and slightly dried, and heated and released to the desired degree by the heating unit 22. With the help of all the ventilation fans, a new circulation cycle is started by entering the tunnel vents (1000) and into the kiln volume (6). The heating method as described above provides an effective way to dry wood without heating the wood to a high temperature, which causes known drying defects in past drying treatments, especially if there is a large amount of moisture on and within the wood initially.

The newly developed kiln volume in a simple and surprisingly short time by means of the drying device in the newly developed kiln volume 6 without combining any kind of accessories, reloading wood and further heating the air in the manner described above. It can dry by the drying apparatus in (6). Since in most cases no additional air heating is required, air passes through the passage 30 near the air deflection plate 3 and the system vent 111 is opened and even functionally as shown in FIGS. 6 and 7. Newly developed drying methods removed can be implemented. By implementing the newly developed drying method, the microclimate ventilation unit 1211 and the ventilation holes 12 1 and 122 are closed.

Therefore, according to the present invention, the difference compared with the solution of the known drying method is to physically prevent the repetitive circulation and the mixing of the dry air and saturated air which can cause low efficiency. By operating the ventilation fans 41, 42, 43, 44 of the ventilation part 40 and the ventilation fan 25 and the ventilation fan 71 of the heating condenser 2, proper air circulation is generated. The outside air entering the kiln compartment (1) and continuously into the kiln volume (6) passes through the open system ventilation section (111) and is then guided through the kiln volume (6) and through the self-regulating ventilation section (31). It is then functionally or permanently removed mostly or permanently through the heating condenser 2 with the heating section 22 but is guided to the air passage 30 through the tunnel-type vent hole 1000 by the ventilation fan 25. When the system vent part 111 is in the open state, air from the air passage 30 cannot enter the kiln volume 6 again, but is exhausted from the kiln compartment 1 to the outside atmosphere. Only this dry fresh air can come into contact with the dry wood. Those skilled in the art should understand that the fresh air introduced must be treated in several ways in the event of extreme climatic conditions which may be achieved by accessories which do not affect the principles of the present invention.

The drying apparatus according to the present invention is capable of controlling and transferring moisture from wood under specific atmospheric conditions by air movement, and is used for drying processing of all wood products regardless of size to meet the transport container size and transport volume. By improving the quality of the dry wood including the conventional drying effect, the drying apparatus can be used by the user as a fixed type or a movable type.
