Description

The group of inventions relates to the woodworking and wood-chemical industry, in particular to equipment for drying wood and methods of moving a trolley with wood, and can be used in the design of drying machines.

Known installation for drying sawn timber (patent for invention No. RU2042093 published on 20.08.1995), containing a drying unit, including a heat-insulated sealed case with air ducts placed in it, thermometers with a wetting system to control temperature and humidity, a rail track, a transport gate, and a hardware unit , including a fan with air ducts, a heater and a condensing device with a closed cooling circuit and a drip tray for collecting condensate, characterized in that the drying and hardware units are made in the form of modules docked using connectors and flexible connections, and the rail track is equipped with a folding section connected to the latter is hinged, and the body is vertically fixed by a lever interacting with the hinged section, while the design uses swing or sliding doors of the chamber.

The use in the design of the described analogue of swing (wing) or sliding doors has a number of disadvantages.

When opening swing doors fixed on hinges, free space is required outside the working area of the chamber; Since doors in industrial and vacuum drying chambers are heavy, powerful force hinges are required that can withstand lateral loads; in addition, the structure of the door opening must withstand deformation loads arising in the open position of the door; it is difficult to load materials into the chamber from the side where the door is open. Sliding door designs also require free space outside the working area of the chamber; an additional design of the guides is required to roll the power door out of the chamber.

In addition, the described design does not provide for special means for rolling up and rolling out trolleys with lumber.

The closest technical solution, selected as a prototype for the claimed drying complex, is a dryer (patent for invention No. RU2244228, published on 01/10/2005), containing a drying chamber connected to heating and compressed air systems with a stack clamping device, a rail track, a pallet truck, removable rail, characterized in that the clamping device is made in the form of separate elastic chambers according to the number of inter-row spacers in the horizontal row of boards along the length of the stack, the drying chamber also contains a hinged cover fixed in the upper part of the chamber inlet. The dryer works as follows. In the initial position, the pallet truck is on the track. Planks are stacked on the platform of the undercarriage. When forming a stack, inter-row spacers are stacked vertically, one above the other. The distance between the spacers must be equal to the distance between the elastic chambers of the dryer. The outer spacers are flush with the ends of the stack. After the end of the formation of the stack with the open hinged lid, the stacker trolley with the stack is moved along the rail tracks into the drying chamber. The hinged cover of the drying chamber is closed. The valves are opened, compressed air enters the elastic chambers through the pipeline. When filling the chamber volume with compressed air, they move the pallets until they come into contact with the stack, while the stack is pressed. Then the fan turns on and hot air after the heat exchanger enters the pressure panel through the discharge line. From the discharge panel, air enters the stack and then to the suction panel, then to the suction pipe. Drying of the stack continues until the final moisture is obtained. The pallets are lifted by springs, the pallet truck with a stack rolls out of the drying chamber without hindrance.

The disadvantages of prototypes are:

- an increase in the total height of the entire system, which entails special requirements for the height of ceilings and significantly limits the possibility of placing drying chambers with such door designs in closed rooms;

- the need to mount and dismantle separate removable rail tracks;

- the lack of special means of rolling out and rolling up the trolley complicates and delays the drying process.

The closest technical solution chosen as a prototype for the proposed method of operating the drying complex is a vacuum drying chamber and its operation method (patent for invention No. RU2215954 published on November 10, 2003), containing a body in the form of a horizontally oriented cylinder with internal panels for condensate drain and end a cover mounted on a pivoting arm with the ability to open and close the chamber, rail tracks for installing a cart with a stack of wood, a vacuum station, means for connecting temperature and humidity sensors connected to the control panel, as well as devices for connecting flat heating elements of zone heating of wood, placed in rows in a stack, characterized in that the panels for condensate drain are made in the form of sheets of fiberglass, obliquely placed in the upper part of the chamber at an angle to each other on both sides of the vertical plate symmetry planes of the housing with the formation of a gap for steam to enter the upper part of the chamber, and the devices for connecting heating elements and sensors are made in the form of two boxes with panels of electrical connectors connected to a power source and a control panel equipped with at least first and second thermostats for controlling heating elements in different areas of the stack. The camera is operated as follows. The loaded cart is rolled along removable rails into the chamber, heating elements and sensors are connected by cables to the corresponding connectors (connectors) on the panels in the boxes. After that, the rails are removed and the cover is rotated and attracted by the clamps. After drying is completed, the chamber is cooled to, after which air can be introduced into it and the lid is opened. Then all electrical connectors (connectors) are undocked, all cables are removed. Removable rails are installed and the trolley is rolled out of the chamber until it stops along the access roads.

The disadvantages of prototypes are:

- when opening hinged swing doors, free space is required outside the working area of the chamber;

- the need to mount and dismantle separate removable rail tracks;

- the occurrence of lateral deforming loads when using the method of opening and closing the door, made on a hinged connection in the form of a pivot arm;

- the lack of special means of rolling out and rolling up the trolley complicates and delays the drying process.

The objective of the claimed invention is to eliminate the above disadvantages.

The technical result to be achieved by the present invention is to remove the lateral deforming load on the structure of the body and the opening of the drying chamber, save space outside the chamber area, allow free access to and load the trolley platform from any side, the possibility of integrating a section of the rail track for rolling out the trolley into door structure, while giving it additional rigidity, reducing the means of mechanization and simplifying the operations associated with the operation of drying cabinets, vacuum chambers and chambers for heat treatment and drying of wood, namely, simplifying the process of rolling out and rolling the trolley, as well as opening and closing the door of the drying chamber , due to the use of one winch to perform the listed technological operations.

To achieve the specified technical result, a drying complex and a method of operating the drying complex are proposed.

The drying complex consists of a drying chamber with a hinged door, which is the base of a part of the outer rail track, a trolley with a cable, an outer rail track, an inner rail track, a hinged door support, and the node connecting the door to the chamber body is located at the bottom of the door leaf, which makes it possible to remove lateral deforming loads from the chamber body, while the door in the upper part is equipped with a winch, in addition, a trolley roll-out unit is installed at the beginning of the outer rail track, and a trolley rolling unit is installed at the end of the inner rail track, behind which the trolley cable is wound.

Also, the drying complex can be performed as follows.

The hinged door support is also the support for the outer track.

The door of the chamber is opened by lowering it forward and in the horizontal position the said door is a support for the section of the rail track along which the trolley rolls out and rolls in.

On the inner surface of the door there is a part of the rail track along which the trolley rolls out and rolls up.

The winch installed in the upper part of the door together with the winch cable attachment allows you to open and close the chamber door.

The winch installed in the upper part of the door together with the roll-out and roll-out units allows the roll-out and roll-out of the trolley to be carried out.

Contains track inserts that connect the inner and outer rail tracks to a section of track located on the inner surface of the door.

The method of operating the drying complex includes the following technological operations: opening and closing the door of the drying chamber, rolling the trolley out of the drying chamber, rolling the trolley into the drying chamber, and in the closed state of the door, the winch cable is fixed in the upper part of the drying chamber body and is in a taut state, opening the door carried out by unwinding the winch cable to the position in which the door rests on the hinged door support, after which the winch cable is wound behind the roll-out block and attached to the trolley, the winch is turned on, thereby rolling out the trolley from the chamber onto the outer rail track, after loading the trolley, the winch cable is connected with the trolley cable, which is preliminarily wound behind the rolling block, turn on the winch, thereby rolling the trolley into the chamber, after which the winch cable is disconnected from the trolley cable, fixed in the upper part of the drying chamber body and, turning on the winch, close the door.

The chamber door is opened by lowering it forward.

After opening the door, rail track inserts are installed on it, connecting the inner and outer rail tracks with the track section located on the inner surface of the door.

The winch cable is attached to the top of the drying chamber when opening and closing the door. If, with the door open, the track section integrated into the door leaf does not connect to the outer rail track and to the inner rail track, track inserts are placed on the door and fixed between the inner track and the track section integrated into the door leaf, and between an external track and a track section integrated into the door leaf, forming a single track for the movement of the trolley.

The essence of the invention is illustrated by drawings.

The drying complex consists of a drying chamber 13 with a hinged door 7, a trolley 8 with a cable 5, an external rail track 11, an internal rail track 10, a hinged door support 9, which is also a support for an external rail track, and the node connecting the door 7 with the chamber body 13 is located in the lower part of the door leaf, while the door 7 in the upper part is equipped with a winch 1, and a section of the rail track 14 is fixed on the inner surface of the door 7, in addition, at the beginning of the outer rail track 11, a cylindrical block for rolling out the trolley 2 is installed, and at the end of the inner rail track a cylindrical rolling block for trolley 3 is installed, behind which the trolley cable 5 is wound.

When installing the door 7, bearing hinges (not shown in the figures) are fixed to the lower end of the door and the lower end of the door opening in the horizontal plane. Bearing hinges are the connection unit of the hinged door 7 with the chamber body 13. In the closed vertical position, the door 7 rests on the hinges. When opening, the door 7 moves to a horizontal position with the help of a winch 1 and rests on the support of the hinged door 9, which is the base of the outer rail track 11. The section of the rail track 14, integrated into the door leaf, connects the outer rail track 11 and the inner rail track 10 through inserts 12 ...

An example of the implementation of the method of operating a drying complex.

In the “door closed” position, the trolley 8 is inside the chamber, the winch cable 4 is fixed on the camera body on the cable 6 mount and is in a taut state. To open the door 7, the winch cable 4 is unwound, the door opens and rests on the support of the hinged door 9. Next, the inserts of the rail track 12 are placed on the door 7 and fixed between the inner rail track 10 and the outer rail track 11, forming a single rail track for the movement of the trolley ... Then the winch cable 4 is wound behind block 2 and is attached to the trolley 8. When the winch 1 is turned on, the trolley 8 rolls out of the chamber onto the outer rail track 11. To roll the trolley 8 into the chamber, the winch cable 4 is wound under the trolley and is connected to the trolley cable 5, In this case, the trolley cable is wound behind the rolling block 3 and is fixed on the trolley 8. When the winch 1 is turned on, the trolley 8 is rolled into the chamber onto the inner rail track 10.

Thus, the winch installed in the upper part of the door together with the fastening of the winch cable allows opening and closing the chamber door, and in the horizontal position of the door, installed in the upper part of the winch together with the rolling out and rolling units, allow the rolling out-rolling operation of the trolley.

Analysis of patent and scientific and technical literature did not reveal technical solutions with a similar set of essential features, which allows us to conclude that the claimed group of inventions meets the “novelty” criterion.

The claimed essential features that predetermine the obtaining of the specified technical result do not explicitly follow from the prior art, which makes it possible to conclude that the claimed group of inventions corresponds to the patentability condition "inventive step".
