Description

BACKGROUND OF THE INVENTION The invention relates to batch-casting machines for the manufacture of fibrous nlies.

A feature of the casting machine described below is in the following elements: a casting machine, a grid conveyor, a high-pressure hydraulic press, a drive roller table and a hydraulic pick-up for stacker carriages.

The drawing shows a machine in three projections.

The casting device 1 consists of a vacuum chamber 5, a molding box 6, a hydraulic lift 7 and a dosing tank 9.

The vacuum chamber 5 serves to create a vacuum under the casting plate in the forming box on the grid of the grid conveyor 3. The vacuum chamber has a grille 8 along which the grid of the grid conveyor moves. The vacuum chamber with two tubes is connected to the receiver of the vacuum pump. The vacuum in the vacuum chamber is created by a vacuum pump. Vacuum reaches 600 mm Hg. Art.

The molding box b, which serves to receive the mass from the dosing tank 9 and the plate ebb, is installed on the vacuum chamber 5. Lifting and lowering the molding box 6 and pressing it to the grid and the vacuum chamber are performed by two hydraulic lifts 7. The lower edge of the molding box has a rubber seal, that the bottom edge of the box during the casting of the plate is tightly attached to the vacuum chamber, clamping the grid. The molding box in the lower part is divided across the partition a, so that two plates of specified sizes can be cast at the same time.

A high pressure hydraulic press 2 is used to press the cast plate in the casting machine to a predetermined size on the grid of the grid conveyor, under which is the press plate, which is a grid.

The grid conveyor 3 serves for pouring and moving the plates. The ebb of the slab takes place in the mold box 6 on the endless grid of the grid conveyor.

No. 83783

For this purpose, used paper machine grids can be used. The grid conveyor is driven by an electric motor through a gearbox. Periodic and re-guided grids (with an interval of up to 5 mip.) Are performed by stopping and starting the electric motor. Tensioning and straightening of the mesh is performed by means of an i.e. live device. Under the vacuum chamber, the screen is deflected downward by a deflection shaft.

Drive roller 4 serves to receive pressed plates from under the press and load them into the working trolley. The drive of the roller conveyor receives from the grid transceiver, the removal of finished slabs from the roller table 3 is led through the base frame 10. The drying frame, made in the form of a rectangular lattice, is laid in the intervals between the roller rollers in such a way that the frame parts forming the frame grid are aligned with by the breaks of the rollers with the rollers, and the intervals that form the living section of the frame, coincide with the installation location of the rollers. With the help of a lifting carriage, the slab, along with the frame, is pushed into the gap of the multi-storey cart. The trolley is moved by means of a hydraulic lift in a vertical plane, combining the loading floors with rollers.

Work maschiny occurs as follows. by vacuuming the mass of the dosing tank into the mold box 6, the vacuum chamber 5 is filled with water slightly higher than the grid, and then the mass is lowered by opening the valve 12. After the end of the vacuum, the masses turn on the vacuum pump and it sucks the water out of the chamber through the receiver. Under the action of vacuuga, the plate is dehydrated on the grid of the grid conveyor in the molding box. After dewatering, a hydraulic lift 7 is switched on, which raises the forging box, followed by the grid driving, the cast plates move the iodine press, the conveyor mesh stops, the press turns on, and the pressed plates occur. At the same time, the forming box is lowered and the next plates are cast. The next movement of the grid, pressed plates from under the press, previously released from the pressure of the presses, go to the roller table, and the molded new plates in the mold, the iodine press goes to him. Plates from the roller table by means of the pre-installed installed removable frames are rendered together with the frame and, with the aid of the carriage, the carriages are easily slid into the floor of the trolley. After filling all the floors, the trolley is fed into a tunnel drying chamber. A cast plate on the frame may come;) for the piece also on a multi-plate hot press.
