SU204A1 - Rotary filter press for squeezing coagulated peat mass, etc. of works - Google Patents

Description

The dehydration of coagulated peat by pressure depends on the volume of the compressible layer and the ability of not tempering and peremianiya it: the thinner this layer is, the faster it is to:) remove water from the peat and the water; the initial product is obtained. In the proposed rotary filter press, the authors strive to satisfy the above; these requirements by dividing the peat mass into the press into a number of individual thin layers that are pressed between the filter discs.

FIG. 1 filter press is shown in vertical section; in fig. 2 is shown in horizontal |, Noah projection and partly in section; in fig. 3 is given a radial section of the filter disk and in FIG. 4 shows the structure of the filter layer .I

A rotary filter press consists of a stationary outer drum 77, in which filter disks 78 rotate on a shaft 75. A mass, subject to release J, is injected between the disks with a special filler 2- W, Fig. 1 and 2,: or in another way and together with them, an almost complete circle runs from entrance 24 to exit 25. To sub-:

keep the pressure constant, and, even by some CTeneini, can increase the pressure by the end of the press, between the individual. due to the bending of the same pads, the mass is pushed out of the press through the sleeve 25. To produce axial pressure, the opening disks 79 are made more durable, on both sides around the circumference, while rotating, they are pressed by the rollers 23, reinforced in the back of the outer drum 77. The entire machine is mounted on frame 7 and is driven by a motor 77 with a worm gear 12 and a gear coupling 73 and J4.

Filter discs, FIG. 3 and 4 are castings provided on both sides with annular grooves 27 and sparse radial grooves 30; the channels of the latter are terminated by openings 37 in the hollow shaft 32, the inner channel of which serves to remove water that is collected along the grooves in an extraneous manner. Radial grooves 30

are covered with plates 28 with holes 29 through which water from the annular grooves 27 passes li grooves 30. For the o6pa3oiiaiuiM of the filter bed, the KanaBOJC serhe plate on the cast iron surface, on the Toii and the other side, is superimposed, 4, first a grid of 26 is thick, then a grid of 25 is fine, and finally a wire of iron or steel sheet 24 serves as a III for Ol-damage grid.

National sponsor, FIG. 1 and 2, represents the funnel 7, in which two vertical shafts 8 with blades 10, inclined at an angle of 45 to IopnZONT}, which by their turning, press the mass down, run it into cylinders 5 with pistons 4, driven by saline from the low 2. The mass is ported through a two-fold bed to apache 6, not the low mass in the opposite direction.

Rotational filter press to squeeze the peat mass, but to coagulate, and so on. work, characterized by the use inside the cylindrical casing 17 of a number of filter discs 18 mounted on a rotating hollow 1st shaft 15 and the section 1x from each other with fixed metal cores2 (9, such a shape that the pressed material introduced under pressure in the radial with respect to Direction-blind discs are gradually compressed in the interstices between the discs and then removed outside the casing.
