Definitions
- the present invention refers to a tank for a water-treatment device, for example a device for decalcifying the water supplied by an aqueduct.
- homes or condominiums are equipped with such a type of device, for example to decalcify the water, or in any case, alter its physical-chemical characteristics and make it more suitable for uses, for example as drinking water.
- the water-treatment devices are inserted upstream of the domestic or industrial distribution network, and generally comprise a tank that is connected to the water network. [0006] . During device operation, these tanks contain water at a high pressure compared with the characteristics of the distribution network downstream of the device, and a mass of organic resins, whose composition is connected with the specific treatment, to which the water is subjected. [0007] . In any case, said tanks are made of a material that is suitable for contact with the water, which may be used as drinking water.
- said tanks have an internal coating and a cover for reinforcement.
- connection devices such as a thread
- the object of the present invention is to create a tank for a water-treatment device fitted with an opening that has such characteristics to increase resistance to elevated working pressure or tank testing.
- This object is achieved by means of a tank made according to claim 1.
- the claims depending on this describe possible variations.
- the tank can be made in accordance with the construction method according to claim 18. Claims depending on this describe variations of implementation of said method.
- FIG. 1 shows a partially sectioned perspective view of a tank according to the present invention
- FIG. 1 represents a sectioned surface view of an opening area of the tank in figure 1
- FIG. 3 shows a sectioned surface view of an insert of the tank in figure 1.
- a tank for a water-treatment device is globally indicated with reference numeral 1.
- the tank 1 comprises an internal coating 2, which extends prevalently along a longitudinal X-X axis, between a closed bottom and an opening area 6 with an opening 8 to the atmosphere.
- said bottom can be made according to the characteristics illustrated below for said opening area 6.
- the coating 2 comprises a wall of coating, between said bottom and said opening area, which is basically cylindrical, and surmounted by a cap wall 9a that culminates in a neck 9b, marking said opening 8, and projecting longitudinally from said cap wall 9a.
- the coating 2 is made of a coating material that is compatible with water, in other words, a material that does not release fragments and cause processes of chemical deterioration, or release unwanted, harmful or similar substances, when it comes into contact with water, even after lengthy periods of time.
- said coating is made of a plastic resin, for example high-density polyethylene (HDPE) for alimentary purposes .
- the tank 1 also comprises a hollow insert 10, connected to said coating 2 on a level with the opening 8 of this.
- the insert 10 comprises an annular wall 12, for connecting said insert 10 to the coating 2, and a collar 14, connected to the annular wall 12, projecting externally from the coating 2, marking the opening 8.
- the annular wall 12 preferably comprises gripping devices suitable for making a notch for connection between the coating 2 and the insert 10.
- said gripping devices comprise at least one annular projection 16 that projects radially from said annular wall.
- said gripping devices comprise a variety of annular projections 16, spaced out longitudinally between each other and projecting radially from the annular wall.
- the collar 14 preferably projects radially in relation to the annular wall 12 of the insert, defining a touching crown 18, an annular lateral surface 20 and a free crown 22.
- the insert preferably presents an annular groove 24 on a level with said touching crown 18, which is suitable for holding a sealing ring 26.
- the touching crown 18 appears as the counterpart of the neck 9b of the coating 2.
- the insert presents an annular indentation 28 on a level with said lateral surface 20. [0032] .
- the insert 10 presents a threaded part 30, which is suitable for connecting the tank 1 to a valve of the water-treatment device and an entrance part 32, flaring towards the inside of the coating 2.
- the insert 10 is preferably made of a material that is harder than the coating 2 material .
- the insert 10 is made of a plastic resin, such as high-density polyethylene (HDPE) for alimentary purposes, for example with glass fibres.
- HDPE high-density polyethylene
- the tank 1 comprises an external cover 40, which covers the coating, at least in part, since it is in close contact with this.
- the cover 40 preferably comprises at least one bundle of fibres 42 that is wrapped tightly several times around the coating 2.
- said bundle comprises glass fibres .
- said cover 40 comprises a matrix in which said bundle of fibres is buried.
- Said matrix is preferably an isophthalic neopentilic resin, with the optional addition of colorant and filaments in glass fibre.
- the cover 40 comprises a portion of covering 50 covering the collar 14 at least partially, which is in close contact with this, thus strengthening the connection between said insert 10 and said coating 2.
- the portion of covering 50 penetrates into the annular indentation 28 of the insert 10, at least partially, further strengthening the connection between said insert and coating 2.
- the tank 1 can be made according to a construction method, which envisages making the insert 10 separately from the coating 2, for example for pressing. [0043] . Said method also foresees a phase of production for the coating 2 connected to the insert 10.
- Said phase can be carried out in a press for blowing, with a support for the insert 10, a relatively mobile die and a counter-punch, devices for blowing air into the cavity between the die and counter-punch in closed configuration and devices for feeding a soft tube between the die and counter-punch in open configuration.
- said coating production phase can be carried out in a rotational press.
- the insert 10 is positioned on the support between the die and the counter-punch; the sealing ring is inserted into the relative annular groove. [0047] .
- the bundle of fibres is wrapped several times around the collar 14 of the insert 10 and then continuously around the rest of the coating 2.
- the tank presents a high resistance opening, suitable for resisting high working pressure or tank testing.
- the tank presents a longer working life and improved features of seal and resistance in time.
- the insert results strongly connected to the coating.
- the insert is made of a harder material than that of the coating material .
- the portion of covering of the collar and the covering of the coating create a continual barrier, which prevents external leaks or losses.
- said matrix in which the bundle of fibres is buried contributes to creating said continual barrier.
- the portion of covering, which envelops the collar holds the insert and, in particular, it holds said collar in contact with said neck of the coating.
- the sealing ring positioned between said gripping devices of the annular wall and said portion of covering, prevents external leaks or losses.
- the covering increases the resistance of the coating also on a level with the cylindrical wall and said cap wall .
- the bundle of fibres wraps the coating tightly, and the matrix in which it is buried, contributes to creating a compact layer, which opposes the action of the high pressure inside the coating, which is in a state of traction over the whole of the coating.
- said bundle of fibres reacts in a way that can be compared to the metal rings associated with the walls of wooden barrels, in a uniform manner over the whole of the coating, guaranteeing the numerous aforesaid additional advantages .
