SUPPORT STRUCTURE OF A TREATMENT MUD PLANT AND RELATIVE

TREATMENT MUD PLANT ***

DESCRIPTION

Field of the invention

The present invention relates to a support structure of a treatment plant of mud, in particular a clarification and dehydration plant of sludge derivatives, for example, by the work of stone.

Furthermore, the present invention relates to a treatment plant arranged on said support structure.

State of the art

Are known the plants of clarification and dehydration of sludge which is derivatives, for example, by the work of stone. Such plants are commonly used in slots of stone or in companies that made working of this stone material, where operations of cutting, breaking, removal or the like are provided. Such operations make waste in the form of sludge, which must to be disposal. In particular, such plants allow to treat the sludge to obtain substantially: a solid component and a liquid component. The solid component is extracted from a filter press. The filter press allows to dehydrate the sludge to obtain solid mud, easily to be disposed of. By the filter press is extracted also a liquid component, which is in turn treated and reused, where necessary.

Associated to the filter press other treatment machines such as silos of settling, homogenizer of sludge, reservoirs, conveyors of material etc. are provided.

The above described known type plants, even if with a small size dimension, i.e. configured for treating reduced flow sludge measured in m ³ /h, have to be mounted/removed to loco and require transports of the various components disassembled to each other. Therefore, these require passive time of assembly/disassembly as well . setting operations of the various treatment machines by expert operators, so that these can carry out the operative treatment cycles in a favorably way. The passive time influences the installation costs .

It is felt therefore the need to provide a treatment plant that is conformed to exceed such drawbacks, and that is easily and quickly arranged on a site work to minimize the passive time of installation, for a ready use.

With reference to Fig. 1, a support structure 1 of a treatment plant of mud is shown, wherein the treatment plant comprises at least one treatment machine, in particular more machine 2 that operatively connected to each other are adapted to receive as input a flow of mud or sludge to treat, for example sludge derivative from the work of stone, or sludge derivatives from excavations, to obtain respectively as output a solid component and a liquid component separate to each other. In particular, the process provides a dehydration of the sludge. The solid component is thus easily disposal and withdrawn from the work site through bulldozer or camion means, whereas the liquid component once treated and clarified can be reused in the process.

The support structure 1, according to the present invention, comprises a support frame 3 having a plurality of longitudinal 31 and transversal 32 beams that define a base quadrant 33, normally open. The main feature and the advantages of a girders structure to will be described then.

On the base quadrant 33 are arranged lock means 4 of releasable type which is conformed to lock at least one treatment machines 2. The treatment machines 2 and their components are connected, for example by fastening portions 41 and lock screws to the beams. Furthermore, the support structure comprises hanging means 5 arranged on the frame 3 that define a plurality of hanging points 51. The hanging points 51 allow to prearrange cable or other elements so that the frame 3 is moved by a lifting means (not shown) .

In particular, the hanging points 51 is arranged near the vertices of the base quadrant 33, as well as - preferably - in intermediate points of the same, such . that the frame 3 maintains a configuration substantially parallel to the plane of the ground P during its handling. In this way, the support structure on which is mounted the plant or part of it can be loaded or discharged on/from a vehicle, as a single monobloc. Further details structural of this solution are described then .

The fastening means 5 are, for example, ring portions 51 conformed to allows the connection of cable in turn functionally connected to the lifting means.

In this way, the plant that is arranged on the frame assume a movable configuration on carrying means, reducing remarkably the installation costs operations.

In a first exemplary embodiment, as better shown in Fig. 2, the support frame 3 comprises intermediate beams 35, 36 arranged longitudinally and transversally in the base quadrant 33 that define substantially a grid structure with more quadrants 33a, 33b, 33c, 33d. In particular, each quadrant defines an area of installation of a respective treatment machine. The beams 35, 36 realizes a support for fastening means 4 through which the machines are integrally connected to the frame.

Furthermore, the support structure comprises a stabilization means 6 of the support frame 3 in the plane of the ground P.

In particular, the support frame 3 assume _. a box-like configuration. Such box-like configuration of the frame allows to stack to each other more box-like frames so that the treatment machines 2 mounted on their inner volume can be easily connected to each other, and so that the layout of arranging on a site work is of minimum encumbrance, as shown in Figs. 5, 6 and 7.

In a first exemplary embodiment the treatment plant comprises a plurality of treatment machines mounted on the support frame 3, 3' . The treatment machines are arranged in way suitable for not protrude from the area defined by the base quadrant 33.

For example, the plant shown in Figs. 1 and 2 comprises mainly a filter press 2a, a silos decanter 2b, a homogenization unit of sludge 2c, a compressor 2d and different reservoirs of water.

Such plant is adapted to treat a medio-small hydric flow and comprises all the components of a depuration and dehydration standard plan of sludge in a single "block" which can be easily moved, for example by ship nave or train.

In a second exemplary embodiment, the plant comprises a treatment machine mounted each on a respective support frame 3, 3' .

In particular, the plant comprises a treatment machine mounted each on a respective box-like frame support 3' , to form a single treatment unit.

In particular, the support frame box-like 3' comprises a base face, a head face opposite to the base face and side faces arranged between the base face and the head face. The side faces comprise at least one apertures, in order to prearranging connection devices between various treatment unit.

The open configuration of the faces allows to interface the different machines to each other, prearranging hydraulic connection systems, electric and other.

In an example shown in Figs. 5, 6 and 7, the plant provides at least one filter press unit, where it is located also a system for extracting the sludge, a dedicated homogenization machine of sludge, a clarified unit of water, a unit to prepare the various chemical solutions which is used also as monitoring and controlling station of the plant, and at least one support frame 3 where silojs 2b are arranged. Such plants cover a requirement of a medium and large required hydric. Such configuration of plant, according to the present invention, is completely movable and modulable. Owing to its modularity in unity, to the components chosen and to the size designed, can be easily transported on camion or via sea and can be adapted to each work condition and site .

According to the required hydric necessary, the plant can be equipped with variable number of unit and size of the machines specially designed.
