Description

The utility model relates to the structural elements of sewage treatment plants, in particular, plants designed for biological treatment of domestic sewage sewage of detached houses and cottages.
The tank is the main structural element in the biological treatment plant for domestic sewage and its body can be made of various materials. Typically, the shells of these reservoirs are divided by partitions into hydraulically interconnected spatially coupled compartments (receiving, primary and secondary sedimentation tanks, aeration tanks, etc.), in which technological equipment is installed (airlifts, aerators, pipelines, compressors, etc.), see, for example, SU No. 1174385, M.cl. C 02 F 3/02, 1984, RU No. 2228915, C 02 F 3/02, 2003; RU No. 2220112, C 02 F 3/02, 2003; RU No. 2233247, C 02 F 3/12, 2002
The disadvantage of analogues is that reinforced concrete or metal cases (made of anticorrosive alloys) are material-intensive, low-tech in manufacture and, or not transportable, or extremely inconvenient for transportation. At the same time, attempts to use other materials for the manufacture of tank shells have not yielded positive results since such a material must satisfy the following requirements — be chemically neutral, lightweight, durable, and easy to process (including welding) and relatively cheap.
The closest analogue adopted for the prototype of this utility model is a reservoir, the details of which are given in the description of patent RU No. 2228915, C 02 F 3/02, 2003
According to the prototype, the tank body is equipped with a heat-insulated lid and is divided by partitions into spatially conjugate compartments hydraulically interconnected (receiving, primary and secondary sedimentation tanks, aeration tanks, etc.).
The disadvantage of the prototype is that the execution of the tank body is equal without taking into account changes (in the height of the body) of the hydrostatic load, which leads to an overexpenditure of the material during manufacture. In addition, the separation of the partitions from the walls of the tank body and its failure from spacer stresses under the action of hydrostatic load from the inside of the body is possible, especially with fluctuations in the liquid level in the compartments.
The technical problem solved by the utility model is the creation of a simple, technologically advanced in manufacture and reliable in operation tank design.
The solution to this problem is provided by the fact that the tank for biological treatment plants for domestic sewage containing a housing in the form of a tank with a bottom, sides and partitions rigidly fixed in the housing with the formation of spatially conjugate compartments in it, according to the utility model, the housing and partitions are made of sheet polymer material, with the sidewalls made in the form located along the height of the casing of the tiers of the sheets, moreover, in each upstream adjacent tier, the thickness of the sheets is less than an adjacent adjacent tier, and on the outside of the sheets of the lower tiers made reinforcing relief, while the tank is equipped with external and internal reinforcing elements. In embodiments, the external reinforcing element is made in the form of at least one belt of horizontal beams mounted on the sidewalls outside the tank at a height of at least 0.5 sidewall heights, the horizontal beams are made in the form of half-grousers and equipped with mounting holes ; internal reinforcing elements are made in the form of couplers - spacers horizontally mounted inside the housing on the sidewalls and partitions; the external reinforcing element is made of body material; internal reinforcing elements are made of a polymer profile of square or circular cross section, identical in composition to the polymer material of the body; reinforcing relief is made in the form of regularly arranged rows of vertical and horizontal stiffeners, between the intersections of which there are trough-shaped rectangular recesses.
This embodiment of the tank allows to reduce the cost of manufacture, to improve convenience during transportation and installation, as well as reliability during operation
The utility model is illustrated by drawings, where:
- Figure 1 shows a General view of the body of the tank (side view);
- figure 2 - section bb in figure 1;
- figure 3 is a cross section of a smooth sheet of polymeric material of two adjacent in height tiers of sidewalls;
- figure 4 is a fragment of a cross section of a side wall formed from sheets of various thicknesses;
- figure 5 is a sheet of a polymeric material with reinforcing relief (axonometry);
- figure 6 is the same, plan view.
- figure 7 is a section KK figure 6.
The tank for biological treatment plants for domestic sewage, contains a housing with a bottom 1 and sidewalls 2. In the housing, dividing walls 3 are rigidly fixed, which form spatially conjugate compartments inside the housing. Bottom 1 and partition walls 3
made of polymer sheets 4. Sidewalls 2 are made in the form of polymer sheets 4 arranged along the height of the tier body, for example A, B, C, and in each upstream adjacent tier, the thickness (a) of sheets 4 is less than the thickness (b) of sheets 4 c downstream adjacent tier, see figure 3. The tank is also equipped with external and internal reinforcing elements. The external reinforcing element is made in the form of at least one belt in the form of horizontal beams 5, mounted on the sidewalls 2 outside the tank body at a height of not less than 0.5 of the height of the sidewalls 2. The beams 5 can be equipped with lug shelves 6 with mounting holes 7. To reduce the cost of manufacture, it is preferable that the beams 5 are made of housing material (for example, from scraps of material with a smooth surface formed during the manufacture of the housing). The internal reinforcing elements are made in the form of screeds - spacers 8, horizontally fixed inside the body on the sidewalls 2 and partitions 3. It is preferable that the screeds-spacers 8 were made of a polymer profile of square or round cross section, identical in composition to the polymer material of the case, which ensures reliable welding of these elements with a housing and partitions. On the outside of the sheets of the lower tiers, for example tiers A and B of the sidewalls 2, a reinforcing relief is made, while the upper (or upper) tier, for example, tier C, is made with a smooth surface. The reinforcement relief is made in the form of regularly arranged rows of vertical and horizontal stiffeners, respectively 9 and 10, between the intersections of which there are trough-like rectangular recesses 11.
As the polymeric material for the manufacture of the housing, dividing walls and reinforcing elements can be used polyethylene, propylene, vinyl plastic, or other similar materials. However, the most preferred material is foamed polypropylene and its foamed varieties - three-layer integral, extrusion, cast and stamped polypropylene. Foamed polypropylene and its varieties have the best performance for use as a structural material for tanks. This material is chemically inert, has increased durability, does not age, is well processed and welded, is lightweight and relatively cheap.
The tank is usually installed in a pre-prepared recess in the ground, while the mounting device of the lifting mechanism is fixed in the mounting holes of 7 beams 5. In the case of weak, floating soil, lug shelves 6 of the beams 5 protect the tank from displacement when moving the soil. The supply of the tank body with external and internal reinforcing elements allows it to be manufactured with almost any proportions, which is important for high elongated tanks. Internal reinforcing elements also provide redistribution
hydrostatic loads with changing levels of the cleaned fluid in the compartments, which also increases the reliability of the tank. The housing is reinforced, with sidewalls of different thicknesses and heightening relief on the lower tiers of the sidewalls, which makes it possible to rationally distribute the stresses in the sidewalls from hydrostatic load along the height of the tank, thereby reducing material consumption during its manufacture. In addition, the implementation of the tank body, dividing walls and reinforcing elements from one polymer material, in particular from foamed polypropylene (or its varieties), makes it possible to simplify and reduce the cost of manufacturing technology by welding homogeneous materials. Light weight (along with chemical inertness and durability), provides increased portability and reliability of the proposed tank.
