    A device for sedimentation of particles from a liquid in which several plate-formed lamellae are arranged in and inclined at an angle in relation to the tank. The tank on both sides of said lamellae is provided with compartments which are separated by an inclined partition wall in a fluid-proof manner into two elongated partitions. (Through the lower of those partitions the liquid which is to be purified is supplied to the device and is fed through inlet openings at the lowermost edge). The lower of these partitions is provided with inlet openings to the lamellae space, whereby the upper edge of the tank is provided with a overflow to each of the upper partitions which has outlet openings for the purified liquid. The lowermost part of the tank is a funnel-shaped hopper having a sludge outlet.

    The invention relates to a device for the purification of liquids from particles by the method of sedimentation (sedimentation) and can be used in the field of sanitary engineering, in industrial cleaning. Different types of sedimentary devices are known in the form of a reserve with inclined disks, or plates in which the suspension is fed to the upper part of the sedimentation tank and the flow is thus directed vertically downwards from the upper side and then vertically upwards again. The fluid circulates around the plate stack and passes through the inlet openings between the plates, while the precipitated sludge is removed through separate outlets. Since the surface of the precipitated sludge is at the same or slightly lower level than the outlet, the liquid flow and sludge flow can be overlaid with each other, which means that portions of the mlama are whirling, resulting in a reduced sedimentation effect. A known structure in which sedimentation should take place in a number of inclined egrugs, where each slip plane is formed by a cylindrical part, the cross section of the surface of the deposited sludge has the form of a circular segment. However, the surface of sedimentation of plates made of tubes is significantly smaller than the surface of sedimentation of plates of such installations, which include an inclined plane or corrugated discs. A fixed wall of the partition is provided in the device in the lower part of the tubes, which serves to distribute the entry. suspension from the removal of sludge. The walls of the partition are located at right angles to the tubes, which means that the angle of inclination of the tubes cannot exceed 45, because otherwise the sludge opening will be clogged. Also known is the construction of a plate composed of perforated corrugated discs or narrow strips, which generally have a curved cross section and are located at such a distance from each other that there is a gap between them. When using this type of plate, it is not possible to achieve a laminar fluid flow therefore, the basic requirements necessary for the sedimentation of very small particles, such as falling flakes, are not fulfilled. In addition, the flow in this installation mainly has a horizontal direction. The purpose of the invention is to increase the efficiency of sedimentation while maintaining a high sedimentation rate and a smaller working volume, i.e. improvement of the cleaning process. The goal is achieved by the fact that the device is equipped with an upper collector installed along each side wall and adjacent along the entire length, along the outlet collector and a downstream collector, mostly divided by a common partition, and the side walls are below the upper level of the plates and in them before each plastino., at the bottom of the akskhodny collector, the holes are filled. Figure 1 shows the proposed sedimentation device; figure 2 is the same longitudinal section. The installation of sedimentation includes a tank 1 in the shape of a box and four walls 2, 3, 4 and 5, which in their most part ends with a chamber b for collecting sludge with a device for unloading, for example, in the form of a valve 7. In tank 1 there are a number of inclined plates 8 constituting an angle with a horizontal plane of at least 50 ° in the flocculated sludge. The plates are connected along vertical side walls 3 and 5 in such a way that no large amount of liquid can pass from one compartment 9 made up of plates into the other, adjacent compartment. On each outer side of the side walls 3 and 5 of the tank 1 there is an inlet distribution manifold 10, the bottom 11 of which is flush with the lower end of the plates 8. The distribution manifolds 10 are connected to the compartments 9 made up of plates by means of a series of inlets 12 located at the lower part of each plate 8 in the plane of the plate, which forms an acute angle with the horizontal plane. The inlets 12 occupy a portion of the total surface between the plates. The flow rate of the fluid in the distribution manifolds 10 is basically equal to the opposite flow within the same plate, so that the fluid flows through the two opposite inlets 12 are basically equal. A significant amount of energy possessed by the liquid stream is released when the flows meet in the center. The fluid flow and the sludge flow do not cross each other, the fluid flow is distributed as evenly as possible over the surface.
