Description

The manufacture of artificial corks from paper pulp followed by impregnation and npeccoBaHHeMj as well as the use of various presses for these purposes is well known. In the proposed J instrument for the manufacture of artificial corks of paper pulp, a tank is used for the said mass and a removable perforated bottom with holes filled with paper pulp using compressed air blown into the tank. An air press is provided to move the removable bottom and press it to the tank.

The drawing shows a general diagram of the device.

The proposed device consists of a reservoir D for paper and a removable bottom (shape) E with holes d, which, in turn, are screwed in cartridges d, in shape corresponding to the shape of the manufactured plugs. The lower edges of the cartridges d are adjacent to the movable bottom E, the latter is raised and lowered, and also tight to the tank D is carried out by means of an air press P. In the upper part of the device, the agitator A is installed with horizontal blades and the agitator B. prevent paper pulp from taking cottony solution.

In the manufacture of artificial plugs, the raw materials are pre-grinded and washed in an ordinary bulk roll. The threshing mass is lowered into the basin, where it is diluted with water to the desired concentration, precisely set for each case (2–3%). There must be three such pools in production: one operating from which the mass goes to the machine, the other with the necessary concentration and the third in which the weight is needed for work. From the active basin, the mass enters the mixer A with horizontal blades and with vertical, rapidly rotating propeller mixers B. From the common mixer L, the mass is taken from individual machines. A machine of such automata can be serviced by one worker. Each of the individual machines has a propeller agitator B. Through valve C, the mass from mixer B fills tank D. After filling tank C with mass, valve C is closed and hot air is injected through valve C (temperature 100-150; under pressure 10 at. Due to which causes mass dehydration and water through the mass layer in the cartridges is squeezed into the internal cavity of the bottom E, from where, through the hole e on the side of the bottom case E and

at the bottom of tank D, into channel G, and then discharged into the sewer. After the dewatering process, the hot air, in turn, penetrates through the plugs cast in the above manner also into the bottom E and, thus, intensive drying of the plugs occurs, and since drying also occurs under a pressure of 10 at, the warping of the plugs cannot have places. Exhausted during the drying process, but still hot air can be used in a suitable economizer for heating fresh portions of air. If the corks are to be impregnated, then this can also be done after pre-drying in the same apparatus, for which the impregnating composition is supplied to the tank D through the corresponding pipe // and the impregnation and final drying of the corks is carried out under the air pressure. By the end of the drying

The moving bottom E, with the assistance of the dog K, is lowered by 2–3 mm and the cast plugs from the cartridges d fall onto the mesh surface, and then fall down with it. At the bottom stop E, the molded stoppers are mechanically pushed into the conveyor to follow to their destination and the casting process begins again.

The subject matter of the invention.

1. A device for the manufacture of plugs of paper pulp using compressed air, characterized by the use of a reservoir /) for paper pulp and a removable perforated bottom (shape) E with holes d, filled with pulp by compressed air forced into the reservoir D.

2. In the device specified in p. 1, use an air press P assigned to move the removable bottom (shape) E and press it to tank D.
