Description

The invention relates to a device for the transport and / or storage of bulk products such as dry materials in the form of granules and more particularly dry sludge. -chauffantes. Self-heating sludges are sludges resulting from chemical reactions having a dryness greater than 70%, that is to say containing less than 30% by weight of water. They are typically in the form of granulated product, more particularly in the form of granules or balls of size not exceeding 10 to 15 millimeters. Self-heating sludge is typically derived from the treatment of wastewater in wastewater treatment plants. They are likely to self-heat due to internal chemical processes, and self-ignite. Self-heating sludge is considered to be a hazardous material, so transport is subject to specific regulations. These are products classified 4.2, packing group III (weakly dangerous) in accordance with the ADR (European Agreement for the Transport of Dangerous Goods by Road) regulations. Several devices are known for conveying self-heating sludge.

For volumes greater than 3 m3, it is known to transport self-heating sludge in tanks that must obtain official authorization in accordance with ADR regulations. However, transport in tanks (with a capacity of more than 3 m3) is very restrictive because it requires the use of specific expensive equipment subject to regular controls. According to the ADR regulations, it is also possible to transport these products using bags of 1 m3 called "big bag" on a semi-trailer platform. Indeed, the ADR stipulates: "the substances transported in parcels of a volume not exceeding 3 m3 are exempt from the class 4.2".

However, these bags require several manipulations to load, stow and unload the bags on the trailer tray, with expensive equipment to handle and an operator continuously present to control the equipment. The object of the present invention is to overcome all or part of the above problems by a new transport device. The invention aims to reduce the number of manipulations of the operator to reduce the loading time and / or docking and / or unloading. The invention also aims to improve the safety of property and people with regard to the risk of auto-ignition. Another object of the invention is to reduce the number of handling equipment. In addition, the object of the invention is to facilitate the transport of self-heating sludge.

DESCRIPTION OF THE INVENTION These objectives are achieved by a device for the transport and / or storage of bulk products, in particular self-heating sludge, comprising a bucket having a rear discharge opening and arranged to receive and position at least two vats (or packages) in an elevated position with respect to a bottom of the bucket. In addition, the tanks comprise at least one anterior tank remote from the rear discharge opening and arranged to open towards a common discharge space extending below the tanks until the discharge opening. The bucket is tilted back to evacuate the bulk material transferred from the tanks into the dumping space. In this way, the device requires very few operations and especially no complex operation for the operator since it is sufficient to tilt the device by traditional lifting equipment. In addition, it allows to evacuate the contents of each anterior tank quickly by the common spill space. At the same time, the tanks may have a capacity below a threshold below which the risks associated with the self-heating character of the product are eliminated or greatly reduced, for example a regulatory threshold, for example 3 m3, below which the regulatory constraints For storage and transport are lightened According to the invention, the device is arranged to simultaneously evacuate the contents of each tank. In particular, the device is arranged to simultaneously evacuate the contents of each prior tank in the discharge space. Not only does this reduce the number of manipulations of the operator, but above all it allows to unload the contents of several tanks very quickly. According to a preferred embodiment, each tank may have an interior volume strictly less than 3 m 3, preferably between 2 and 3 m 3, preferably between 2.5 and 3 m 3, preferably between 2.8 and 3 m 3.

In addition, each tank, or at least one tank, can be provided to contain dry matter in the form of granules whose main dimension is less than 15 mm. According to a particular embodiment, each tank, or at least one tank, is designed to contain self-heating sludge, that is to say sludge from chemical reactions having a dryness greater than 70% and likely to self-heating and even self-igniting. According to a particular embodiment, each tank, or at least one tank, is designed to contain dry matter in the form of granules whose main dimension is less than 15 mm, and having a dryness greater than 70%, that is to say -It contains less than 30% by weight of water.

Preferably, the at least one anterior tank is arranged to open during the inclination of the bucket, the bucket being inclined in a plane of inclination forming a non-zero angle with respect to a horizontal plane. According to the invention, the tanks are aligned in the bucket in a longitudinal direction of the bucket, all oriented in a defined manner.

Preferably, each tank has a filler flap arranged on an upper wall of the tank so that the contents can be loaded gravitarily in said tank. Preferably, each tank may have at least one drain flap arranged to allow the contents to evacuate gravitarily when tilting the bucket. According to a feature of the invention, each tank has at least one drain flap arranged along a rear transverse side wall of said tank.

Preferably, the positioning means and the support means are arranged to hold the tanks in position during the inclination of the bucket. In this way, the contents can be poured safely. In one embodiment, the tanks are aligned in the longitudinal direction of the bucket. Each vessel is typically oriented in the bucket so that the length of the vessel is transverse, i.e. parallel to the width of the bucket. Preferably, the length of each tank occupies the entire useful width of the bucket, the mounting clearance. According to a feature of the invention, the common discharge space is delimited vertically between the bottom of the bucket and the lower walls of the tanks and transversely by side elevation walls belonging to the bucket. The elevation walls allow to channel the bulk product of the tanks towards the discharge opening. The height of the space is of sufficient size to allow the flow of the product, and this space occupies the entire surface of the bottom of the bucket. It can also be envisaged that the height of the common spill space increases towards the spill opening, in other words from the front to the rear of the skip. It could also be envisaged that the forwardmost vessel in the bucket is adjacent to the bottom of the bucket, without interposing a spill space under this vessel. Preferably, the discharge opening is equipped with a tailgate hinged by its upper edge to the bucket to close the opening when the bucket is in the road position, and to clear the discharge opening during the inclination of the bucket. the bucket by lifting from its opposite end to the spill opening.

This selection comprises at least one preferably functional characteristic without structural details, and / or with only a part of the structural details if this part alone is sufficient to confer a technical advantage or to differentiate the invention from the state of the art. earlier. First of all, with reference to FIGS. 1 and 2, a device 100 for the transport and / or storage of any bulk product and / or dry material in the form of granules will be described. More particularly, this embodiment is intended to transport self-heating dry sludge in the form of granules typically having a diameter of less than 15 mm. According to the invention, the device 100 comprises a bucket 1 arranged to receive and position at least two tanks 20 in an elevated position relative to a bottom 44 of the bucket (not visible in Figures 1 and 2). Each tank 20 is arranged to store and / or transport the self-heating dry sludge. Referring to Figures 1, 2 and 6, the bucket 1 is attached to a hoe 2 type "Ampliroll". "Ampliroll" type cradle is understood to mean a L-shaped metal frame with a horizontal portion 2h extending in a longitudinal direction and a vertical portion 2v. The armature is for example connected to the bucket by welding so that the outer face of the bottom of the bucket is welded to the horizontal part 2h of the cradle 2 and the outer front surface of the bucket is welded to the vertical part 2v 2. Hogwheel 2 is capable of supporting the bucket in a static and dynamic manner, making it possible to manipulate the bucket 1. The bucket is handled by means of appropriate equipment, in particular by a gripping part of the crane 2 such as a handle 2a. Referring to Figures 2 and 6, the handle 2a is located on the vertical portion 2v of the cradle 2, close to the front face of the bucket. In addition, the cradle 2 comprises wheels 2r arranged to facilitate the translation and / or pivoting of the bucket 1 relative to different supports such as the ground or mobile platforms. In addition, with reference to FIG. 2, the "Ampliroll" type 2 cradle can be provided to be tilted / inclined relative to a plane, such as the ground plane or in particular with respect to a truck, so that the bucket is capable of pivoting about an axis of rotation passing through an axis of rotation of wheels 2r of the cradle 2. The cradle 2 allows to hoist the device 100 on a truck equipped with a suitable lifting device, well known in the field of road transport or construction. According to a preferred embodiment, the device 1 is tilting about a transverse horizontal axis. Typically, the tilting is operated by a tilting device conventionally provided on a vehicle of the road and / or industrial vehicle type which transports the device according to the invention. With reference to Figures 1 and 2, the bucket 1 carries five tanks. They have in their upper wall a filler door 25 to allow their filling of bulk product. Preferably, each tank is a metal tank and is adapted by its composition to receive products such as self-heating sludge. Each vat extends over the entire width of the bucket.

According to the invention, and with reference to FIGS. 1, 4 and 5, the tanks 20 each comprise a drain flap 22 arranged along a rear transverse side wall 23 of said tanks 20. Preferably, the flush hatches 22 are substantially vertical and articulated by their upper edge. Each drain flap 22 has the shape of a substantially rectangular flap. Preferably, the hatch 22 is connected to the wall 23 via pivoting means such that at least one hinge on its upper edge and extending in a transverse direction. In one embodiment, each hatch extends over the entire length of the tank. In one embodiment, the hatch extends over approximately the lower third of the height of the tank. The hatch selectively closes a drain opening of the tank. It is advantageous that the lower edge of the emptying opening is flush with the lower face of the bottom of the tank.

All the tanks 20 are aligned in a substantially longitudinal direction of the bucket and positioned on the bucket 1 so that the tanks 20 are all oriented in the same direction. According to the invention, the tanks 20 are oriented so that the emptying hatches 22 open towards the rear of the bucket 1. With reference to FIGS. 1 and 2, the tanks other than the one situated in front are called "anterior tanks". the rearmost of the bucket 1. The anterior tanks are arranged to open to a common spill area 40 (which will be described later). According to the example shown, there are four prior vessels 20 arranged to open towards the common discharge space 40 extending below the tanks 20 to a discharge opening 46 located in the bottom of a rear face 47 of the bucket 1. The common spill area 40 extends between the tanks 20 and the bottom 44 of the bucket. Typically, it covers the entire bottom surface of the bucket, except possibly the region below the tank 20 adjacent to the front of the bucket. Laterally and at the front end, the common discharge space is formed by blind walls of the bucket 1. The rear face 47 of the bucket is traversed by the spill opening 46 whose height and width substantially correspond preferably to those of the common spill area. Spill opening 46 is selectively closed by a hatch 46h. Referring to Figures 3 and 4, each vessel 20 has a wall 24 opposite the vertical wall 23 and also extending in a transverse direction so that the wall 24 is arranged to clear a clearance space for the opening of the drain flap 22 of the adjacent vessel. Preferably, the wall 24 comprises a vertical upper part and a beveled lower part oriented at an angle preferably between 10 and 45 degrees with respect to the upper part. The bevel allows the pivoting of the emptying hatch 22 of the adjacent tank 20. It is thus formed between two adjacent tanks, that is to say between a wall 24 of a tank, more precisely the lower part beveled, and a wall 23 of an adjacent tank, a generally triangular space that communicates freely with the discharge space 40 and which allows the clearance of the drain flap 22 pivoting about its upper transverse axis between its open and closed positions. All the tanks 20 are oriented in a precise direction, that is to say the respective drain hatches 22 of the tanks 20 oriented towards the rear of the bucket, to allow, with reference to Figures 2 and 4, the pivoting traps 22 when tilting the bucket. Thus, by tilting the bucket 1 towards the rear, with reference to FIG. 2, it is possible to evacuate outside the bucket 1, through the opening 46, by gravity the bulk product transferred from the tanks 20 in the discharge space 40, and that the product is evacuated gravitarily out of the bucket 1. According to the invention, all the tanks 20 are arranged to open during the inclination of the bucket, the bucket being inclined according to a plane of inclination forming a non-zero angle with respect to a substantially horizontal plane. According to a particular embodiment and with reference to Figures 1 and 2, the bucket 1 is arranged so that the tank 20 adjacent to the rear end of the bucket not open in the common spill space 40 but directly out of the bucket 1. In this embodiment, the rear tank 20 is identical to the previous tanks. FIG. 2 shows the device in the inclined state, with the emptying hatches 22 (shown in dotted line) having opened in the clearance space. The arrows 43 indicate the trajectory of the sludge or other material transported, which migrates by gravity from the previous tanks into the dumping space 40 and from there through the opening 46 to the outside. In one embodiment, all the tanks 20 are identical.

According to a preferred embodiment, and each tank 20 has with reference to Figures 4 and 5 a locking device 19 for locking the drain flap 22. The locking device 19 comprises with reference to Figures 2 to 5 a crank or a lever 21 arranged to actuate the locking or unlocking. Preferably, the crank or the lever 21 extends outside the tank 20 and even outside the bucket 1 when said tank 20 is positioned in the bucket 1. Typically, all the levers or cranks 21 are accessible from the same side of the bucket 1. Thus to evacuate the contents of each tank, the operator maneuver one or more levers 21, and inclines the bucket 1, by a motorized tipping equipment (not shown) provided on the vehicle (not shown) and the contents of each tank 20 are evacuated via the spill space 40. In this way, the operator performs only simple and fast manipulations. In addition, thanks to the device for locking the tank, it is possible to evacuate the contents of each tank 20 simultaneously or choose to evacuate the contents of one or more tanks 20 independently of the others. The particular arrangement of the flush hatch 22 associated with the elevation allows each content to evacuate without being impeded by an emptying flap of an adjacent tank that could impede the evacuation of the contents. It is possible to separate the tanks from the bucket, for example to load different tanks at different sites, and then to load the full tanks in the bucket previously installed on a truck.
