PT92725B - CHEMICAL AND BACTERIOLOGICAL CLEANING EQUIPMENT OF SAND SOILS - Google Patents

Description

DESCRIPTION MEMORIES the present invention relates to equipment used for cleaning sand beaches, that is, soils containing mostly free rock grains ranging in size from 0.1 to 10 mm located generally along the sea or lakes , places increasingly frequented by vacationers.

the important development of industrial and especially tourist activities along the coastlines causes the phenomenon of pollution to appear: undesirable deposits of debris of all species and also contamination of the sand by pathogenic germs. In addition to the aesthetic aspect, this pollution presents dangers for holidaymakers, dangers of injury to sharp objects, such as broken glass and also the dangers of diseases transmitted by microbial germs that find in the sand a hot and humid environment conducive to their proliferation.

Health authorities are sensitized by this problem, regular cleaning of coastlines. For several machines to make this national or local, so they have to proceed to do it, there are currently t r a b a 1 h o.

This sand is taken to a sieving mat where it is sieved at a time to remove all solid debris (such as bottles, cigarette butts, canning boxes, etc.) before being deposited again. in the soil. ; This machine also comprises, more and more frequently, means of spraying liquid chemical and bacteriological cleaning solution on the sand, which means, preferably, at the level of the sieving mat where the removed sand, in fine particles, can be easily impregnated for a minimum required amount. To this p-purpose, and xp o s i ς · - ó e s can be mentioned the DE 3 209 134, DE 3 147 equipment disclosed 648 and FR 2 612 965.

-3previously, it comprises a fitted rotor that is straight, twisted or bent, spraying is mounted parallel to the rotor pair to spray with liquid solution stirred by the rotating blades.

However, it has been revealed in practice that numerous areas of a beach remain inaccessible to these machines. Indeed, it is necessary first of all to mention the zone of average influx of waves even at the edge of the sea, in which the sand bathed by the water presents itself as a viscous mass, and cannot be harvested or removed in the traditional way. Following this first zone is a second one marked by the upper limit of inflow of waves or tide depending on the narrowness of the coast. This second zone is easily noticed by its appearance hardened by superficial crust and its darker color in relation to the dry sand zones due to the fact that the sand there is still largely impregnated with water. If ef ect i. although the aforementioned machines can collect the surface layer, it appears that agglomerates of sand coming from this upper crust cannot pass through the sieve in any form: static, vibrant, conveyor belt. These pellets will quickly overload the rear waste container.

It seems that these two areas mentioned above are, in fact, the most frequented by the public, even in a period of low turnout. Most people there stay, of course, to play with the waves, to walk on hard ground, to admire the landscape or other considerations. It seems, then, contestable to just clean the dry areas of the beach, as is currently practiced, which only benefits a minority.

In addition, these usually large machines cannot turn in less than a minimum radius of around 3 m. This means that if there is an obstacle on the beach, such as a tent, a tree or a boat, an area of sand that surrounds it cannot necessarily feel clean, despite being very frequented.

-4Finally, it was also found that the wheels of the machines themselves leave behind polluted traces, reducing from 5 to 10% the surface actually treated.

The purpose of the present invention is an equipment comprising means for removing soil in depth in the form of small particles and means for spraying liquid cleaning solution on the particles before their deposition back into the soil, equipment that is more complete, i.e. that is, to allow the treatment of the most important particular areas mentioned above to conclude the work undertaken.

These purposes have not been achieved thanks to equipment that also comprises lateral means of spraying liquid cleaning solution from the side directly onto the ground.

Advantageously, the liquid cleaning solution used in this equipment is an electrolyte of sea water whose concentration in chlorine equivalent is comprised between 200 and 2,000 rag / 1.

According to a first preferred embodiment, the sand soil cleaning equipment comprises means for collecting sand to take it on top of a mat from which it is deposited back onto the ground and located close to the mat spraying on the sand of liquid solution solution further comprises sieving means, cleaning means. This fractionation of the sand crust upstream of the middle collection and

According to a second embodiment, the sand cleaning equipment comprises a rotor fitted with fins and spray means oriented towards the rotor as well as, on each of the side walls, at least one spray nozzle with a decentralized plane oriented downwards.

The invention is described below in more detail with the aid of examples of execution without limiting character, illustrated in the attached drawings, in which 70 44 2

The equipment comprises a chassis 110 mounted on two rear wheels 112 and which is pulled along the beach to be cleaned by a tractor 100. This chassis 110 takes a collection blade 130 located just behind a drum with fins 120, projecting the sand thus collected for an endless sieving mat 140. The fine sand passing through this sieving mat 140 falls back to the ground, while the solid residues are carried to the top of the mat before being poured into a rear container 150.

The liquid solution spraying means are represented schematically by a block 160 comprising a solution reservoir and a pump and by two spray ramps 170 whose facts are oriented directly on the sand projected onto the sieving mat 140.

According to a feature of the invention, this chassis further comprises a cylindrical wire brush 600 located parallel to this drum 120. This wire brush 600 can be lifted off when the machine passes through lower dry areas and clutched in areas whose sand is encrusted. Of course, twisted or curved straight blades can be installed in place of the metal rods that make up the brush. It can; it is also possible to conceive, instead of this brush, a device built by two thick plates with teeth, mounted parallel to each other and animated by a lateral reciprocating movement.

According to another feature, this chassis 110 is furthermore completed on each side by two ramps 400 having one or more spraying nozzles with center plane 420. When not used, this ramp 400 can be lowered backwards as illustrated on the right side. This ramp 400 is put into operation, extending perpendicularly to the chassis 110 as

Advantageously, the length of this ramp is between 2 and 3 m. A plumbing not shown connects this ramp to the reservoir included in 160.

According to a supplementary feature, a special spray distributor 500 is mounted on the top of each of the rear wheels, allowing to permanently clean the sand raised by said wheels. So, the traces left behind by this equipment are themselves free of bacteria.

As can be seen in the figure, this equipment proves to be iritically useful, once the corresponding side distributor 400 has been extended, since the equipment pulled by a tractor can be passed over a second crust-hardened area (13) while spraying and cleaning the first area wet (17).

Combined with the use of a sea water electrolyzate as a liquid cleaning solution as sold under the name I4ERACTTVE, this equipment allows effective cleaning in just one passage of the two particular areas mentioned above.

In addition, if the radius of v, the act of the set does not allow to pass sufficiently close to an obstacle, such as a stranded boat, it is always possible to extend the distributor 400 again momentarily to clean the neighboring area of this obstacle.

The machine illustrated in figure 7 is usually used in alternation with the one described with reference to figure 1. However, this machine, which costs less than the first one, allows for an effective chemical cleaning when a collection of debris is not. still needed.

This machine comprises a frame 115 holding a rotor 135 parallel to the ground. This rotor is provided with its entire length with transverse fins 136 completed with blades that attack the ground. This rotor 135 is animated by a rotating movement thanks to a power connection 125 connecting the tractor 100 to

-Ί a box with speed 126 that transmits the torque of forces to an axis 127 and a set of chains inside a housing 128. Blades, partially represented for better understanding with the figure, contain the sand when projected . A distributor 180 is located above and parallel to the rotor 135 below the blades 117. This ramp allows the spraying of liquid cleaning solution onto the projected sand.

If this machine continues to be entirely effective for the second area of encrusted sand, it is, however, insufficient for the first area whose sand is viscous. In order to clean this first zone when passing through the second, one or more nozzles 430 are provided on one side and the other of the machine, spraying the liquid cleaning solution laterally directly on the ground. Preferably, this nozzle is of the decentralized plane type, as illustrated in figure 2, allowing a harmonious spraying along the line d of approximately 1.5 m. In addition, this nozzle 430 can also be activated momentarily when the machine passes through an area close to an obstacle.

Numerous improvements can be made to this equipment within the framework of this invention.
