Pressure tank comprising a shell, closed with tank head/bottom (2, 3 or 3A), at least one tank head/bottom is flat, equipped with connections (6) and with at least one inspection manhole (7) is characterized in that below flat tank bottom (2) at least one reinforced concrete slab (4) connected to a shell (1) using fixing elements (5) and slab (4) is arranged.

Description

Pressure Tank
The present invention relates to pressure tank used for storage of pressurized mediums as well as for processes with pressurized mediums.
Pressure tanks with their bottom mounted directly on a stable foundation are commonly known. They comprise a cylindrical shell closed with tank heads and bottoms of elliptic or other spherical shapes.
From Polish description of utility model No. 113909 pressure filter tank is known which is closed with flat tank head and bottom and load caused by pressure inside the tank is transferred by suitably shaped tank head and bottom having form of rib reinforced disks.
According to this invention pressure tank comprising shell closed with tank head and bottom, at least one of them is flat, is equipped with connections and with one ore more inspection manholes, has at least one reinforced concrete slab that is connected to tank shell using fixing elements. Reinforced concrete slab is arranged below flat bottom. Above flat tank head, opposite to reinforced concrete slab, upper reinforced concrete slab is arranged that is connected to lower slab with fixing elements. Upper reinforced concrete slab is connected to lower reinforced concrete slab using connecting elements, i.e. tank shell and/or supporting elements. On shell perimeter reinforcements are arranged that are connected to reinforced concrete slabs using fixing element.
Pressure tank according to this invention makes possible loads on tank head/bottom caused by a pressure inside the tank to be transferred to reinforced concrete slabs and then to connecting elements. Due to such construction, manufacture of big size tanks, not achievable today, using simple technologies is possible. It can be done due to replacement of elliptic and other spherical tank heads/bottoms by a flat one. Compared to spherical tank heads/bottoms, manufacture of flat heads/bottoms is easy and less labour-consuming. To produce spherical heads/bottoms special tools and processes are required, and above certain diameter it's even impossible to manufacture such head/bottom under normal conditions, and they cost considerably more money than a flat one. Structurally, strain hardening in form of reinforced concrete slabs is easy to produce and its manufacture difficulty degree is similar to manufacture of reinforced concrete constructions.
Pressure tank is shown on Fig. 1 - 8; Fig. 1 represents filter tank with reinforced concrete slab arranged under flat tank bottom, Fig. 2 - filter tank with upper flat reinforced concrete slab mounted in a shell, with drainage and distribution system, Fig. 3 - filter tank with two flat reinforced concrete slabs arranged outside a shell, Fig. 4 - filter tank with two flat reinforced concrete slabs arranged inside a shell, Fig. 5 - filter tank with upper flat reinforced concrete slab mounted inside a shell, with supporting elements and horizontal lacing, Fig. 6 - tank with upper flat reinforced concrete slab mounted inside a shell and supporting elements, Fig. 7 - aerator tank with upper flat reinforced concrete slab mounted inside a shell, with air distribution system and distribution system, Fig. 8 - reactor tank with medium mixing tank, with deposit collection tank and deposit and medium guiding hopper.
Pressure tank according to this invention is of cylindrical shape, closed with tank head and bottom made of metal sheet and sections welded tight. Pressure tank comprises a shell 1 closed with head and bottom 2,3 or 3 A, at least one of them is flat and strain hardened with reinforced concrete slab. Slab 4 made of reinforced concrete is connected with tank shell 1 in such a way that load caused by inside pressure is transferred by fixing elements 5.
Fig.l shows water treatment filter with pressure tank having flat bottom 2 and elliptic head 3 A. Flat bottom 3 is strain hardened with reinforced concrete slab 4 connected with shell 1 using fixing elements 5. During operation pressure tank is filled partially with filter bed being spread on the tank bottom 2.
On the lateral surface of cylindrical shell 1 connections 6 and inspection manholes 7 are mounted. On shell perimeter reinforcement 8 connected with reinforced concrete slab 4 with fixing elements 5 is arranged.
Fig.2 shows water filter; here water flows in the filter through an upper connection 6 and is distributed by a distribution system 9. Filter is filled partially with sand bed, e.g. quartz sand. Water flows through a sand bed and solids are settled there. Water already filtered flows then by drainage 10 and lower connection 6 to the system.
Filter deposits are periodically washed out with water and air jet. Water and air supplied via lower connection 6 remove deposit collected on a sand bed. Excessive gases are drained through connection 6C. Because water supplied to the filter contains gases pressure inside the filter arises and it is directed evenly toward the shell 1 and head/bottom 2, 3. Loads exerted on head/bottom 2,3 are taken over by reinforced concrete slabs 4.4A first and then by connecting elements, i.e. shell 1 and supporting elements 11 as shown in Fig. 5 and 6. Filter shown in Fig. 3 has head/bottom 2,3 strain hardened with reinforced concrete slabs 4,4A arranged outside the shell 1 and connected to it with fixing elements 5,5A. On external surface of the shell 1 reinforcements 8, 8 A are situated. Fig. 4 shows another solution with arrangement of reinforced concrete slabs 4 and 4A inside the shell 1.
Fig. 5 and 6 show solution for big diameter filter with supporting elements 11 rest on reinforced concrete slab 4 or foundation to support reinforced concrete slab 4A. Filter with supporting elements 11 ace. to Fig. 6 is bound to horizontal lacings 1 IA maintaining reinforcements in a fixed position. Supporting elements 11 can be positioned inside the tank also, and then they rest on the tank bottom 2 and reinforced concrete slab 4, accordingly. Supporting elements 11 relieve effectively tank shell of a load resulting from upper reinforced concrete slab 4A. Pressure tank shown in Fig. 7 is used for water aeration in water treatment plants and water/air mixing plants as well as for temporary water retention before next processing. Pressure tank has a cylindrical shape and consists of a metal shell 1 closed with flat metal head and bottom 2,3 strain hardened with reinforced concrete slabs 4,4A. Water inlet and outlet connections 6 and air inlet connection 12 and inspection manholes 7 are situated in the shell 1 and venting connection 6C is located in the tank head 3.
Inside the tank, above tank bottom 2 air distribution system 13 and below tank head 3 distribution system are arranged. Pressure tank shown in Fig. 8 is used as a reactor tank in water and wastewater treatment processes.
Pressure tank is of cylindrical shape and consists of a metal shell 1 closed with flat metal head/bottom 2,3 strain hardened with reinforced concrete slabs 4,4A.
Water inlet and outlet connections 6 and 6A, deposit drain connection 6B and inspection manholes 7 are situated in the shell 1. Inside the tank, above tank bottom 2 medium mixing and distributing system 14 is located. Above tank bottom deposit collection system 15 and hopper 16 for guiding of deposits and mixing mediums are arranged.
