Description

DEVICE FOR FEEDING A PLANT OF TREATMENT OF MATERIAL AND VIBRATORY MILL EQUIPPED WITH THE SAME FIELD OF THE INVENTION The present invention relates to a feeder device for a material processing plant and to a vertical cone vibratory shearing machine equipped with this device. However, although more especially it is intended for these applications, the feeder device can also be used, in particular, with other types of crushing and grinding machines.

BACKGROUND OF THE INVENTION In order for a vibratory cone breaker to be able to function correctly, it is preferred that the machine operates under load, that is to say that its breaker chamber is continuously fed with material. For this reason, special care should be taken in the design of this type of feeder system. At present, most conventional feeding systems consist of a ramp that is fixed to the appliance itself. The shape and dimensions may vary according to the technology used for the breaking machine. While these devices ensure that P1005 / 00MX, however, has the problem of generating a static pressure that is due, in particular, to the fact that the mass of the materials decreases the efficiency of the machine and restricts its operation. To solve these problems, some devices have been invented, for example, those that have a rotating ramp. Another device has been developed that consists of a small hopper integrated to the cone breaker, but which has a flat bottom equipped with two horizontal discs. One of the discs is fixed to the vertical cylindrical wall and is integrated with it and has openings in the form of spiral arcs, centered in the arch of the disc. The second disk, which is mobile, comprises the same openings but these are a little wider. The displacement of the disk by means of a jack makes it possible to control the openings partially, distributing the feed to the breaking chamber. Another known device is constituted by an arrow emerging on a distribution plate, provided above the breaker and integral with the central cone of the breaker, so as to distribute the material flowing towards the break chamber around the cone.

P1005 / OOMX These devices present the problem of limiting only the processing of fine grain sizes. In addition, in hoppers or storage silos, discharge devices are known which have a conical central unit at the base of the hopper, designed to vibrate and facilitate the flow of stored materials when they tend to stick and / or form inverted U-shapes. . The material is re-centered before it leaves the hopper. However, it is observed that all the aforementioned devices lead, during use in a cone breaker, to the presence of material in the area of the upper portion of the cone, thus providing the lifting of the wear forces, which generate the wear, energy consumption and considerable mechanical stress, which is unnecessary.

SUMMARY OF THE INVENTION The object of the invention is to provide a feeder device that solves the aforementioned problems and makes it possible to protect certain members of the plant equipped with the device, in particular to protect them against the phenomenon of wear. Another object of the present invention is P1005 / O0HX provide a feeder device that can be used with materials that have grain sizes that can vary over a wide range. Another object of the invention is to provide a device that allows the plant equipped with the device to be fed continuously while, at the same time, the static pressure is controlled. A further object of the invention is to provide a vibrating cone breaker, equipped with a feeder device, where the wear on the upper portions of the cone, possibly not active, is reduced or eliminated. Another object of the present invention is to provide a vibrating cone breaker, equipped with a feeder device, wherein the mechanical stresses exerted on the cone are reduced and / or move considerably. Another object of the present invention is to provide a vibrating cone breaker equipped with a feeder device, wherein the static pressure inside the break chamber can be controlled. Other objects and advantages of the invention will emerge during the following description which is provided only by way of illustration and is not intended to limit the invention. According to the invention, the device P1005 / 00MX feeder for the processing plant of material such as, for example, a breaker, includes an outer shell or external shell and a bell, provided at least internally in the outer shell and secured to the latter, the bell is provided so as to be oriented essentially parallel to the flow direction of the material, so as to allow the deviation of the material to protect the members, which are provided downstream of said plant.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for feeding a material processing plant, for example and in particular, a breaker. It can be, for example, a feeder device where the flow of material is facilitated by the vibrations generated by said plant. As shown in Figures 1 to 3, the device 1 of the present invention for feeding to a material processing plant 2 includes an external shell 3. The latter is placed, for example, below a storage hopper 4, from which the material flows, in particular by gravity feed. The external shell 3 has, for example, a rotationally symmetrical shape, in particular frusto-conical or cylindrical. Its axis of symmetry is oriented, for example essentially vertically, in particular in the extension of the axis P1005 / 00MX longitudinal of the hopper 4 and / or of that of the plant 2, which in turn, where appropriate, are also provided to remain essentially vertical. According to the invention, the feeder device 1 also includes a bell-shaped element 6, provided at least internally in the external shell 3 and secured to the latter. The bell 6 is provided so as to be oriented essentially parallel to the flow direction of the material. The latter can thus be deflected in the directions of the arrows 7 and 8, making it possible to protect the members 9 of the floor 2. In fact, the member or members that are provided with low current are no longer, at least partially, in contact with the material. The expression "provided downstream" refers, in particular, to the members 9 being located downstream of the feeder device 1, below the bell 6 and / or, as shown, are covered by the bell 6. The bell 6 is provided, in particular, so as to be level with the outlet and / or emerge therefrom from the outer shell 3. This favors the annular distribution of the material. Therefore, bell 6 has, for example, a rotationally symmetrical shape, for example cylindrical or cylindrical-conical.

P1005 / 00MX According to the exemplary forms different from the embodiment illustrated, the material flows vertically and the axis of symmetry 10 of the bell 6 is provided, on the other hand, as will be evident from the previous explanations, so that it can be oriented substantially in the same direction. The outer shell 3 and the bell 6 are secured to each other, in particular by means of wing members 11, provided so as to be uniformly vertical and uniformly distributed around the axis of symmetry 10 of the bell 6. The feeder device 1 of according to the invention includes, in particular, three of the vane members 11 placed in a star configuration and spaced apart from each other by 120 °, four of the wing members being spaced apart by 90 °. The wing members 11 may be provided, as applicable, in order to be able to orient themselves, for example, each pivoting about an essentially horizontal axis. in this way, they will make it possible, in particular, to adjust the flow velocity of the material by closing the passage between bell 6 and outer shell 3 to a greater or lesser degree, and to moderate the static load.

P1005 / 00MX As illustrated, outer shell 6, bell 6 and / or member 9 are, for example, coaxial. With reference to Figure 4, it will be noted that according to the first embodiment, the external shell 3 is made in one piece. According to another embodiment, which is illustrated in Figure 5, the external shell 3 is constituted by a lower element 12 referred to herein as "ramp" and by an upper element 13 emerging on the ramp 12. In addition, as illustrated in Figures 1, 3 and 4, bell 6 is, for example, made in one piece or, as illustrated in other Figures, constituted by a dome 14 and by a tubular element 15, which fits within the dome 14. When outer shell 3 is formed, as mentioned above, by two independent elements 12, 13, the bell 6, when it is made in one piece and / or its dome, when it is not made in one piece, are in particular secured to the upper element 13. With respect to the tubular element 15, this is assembled, for example, on the ramp 12. According to certain applications, it can also be contemplated to provide a bell 6 that rises upstream of the external shell 3 and here emerges, for example, in the hopper 4. The present invention also relates to P1005 / 00MX a vibratory crusher 2 with a vertical cone 16 and a cracking chamber 17 equipped with a feeder device 1, as described above. As already described, the device 1 is provided between a storage hopper 4 and the breaker 2 and allows the latter to be fed with material, in particular through the combined effect of gravity and / or the vibrations generated by the breaker 2. The bell 6 of the feeder device 2 is provided, for example, above the breaking chamber 17 of the breaker 2 and therefore makes it possible to protect the members 9 provided therein, isolating them, at least partially, from the flow of material. . This implies, in particular, that the cone 16 provided according to the different exemplary forms of the illustrated embodiment, emerges externally above the breaking chamber 17. The bell 6 is then provided in order to be able to cover, at least partially, to the emerging end 18 of the cone 16, a residual space 21 being provided between the two members. As it is no longer directly surrounded by material in the area of the end 18, the cone 16 is free in its movement and at least in this area, that is, in particular in an area where the cone 16 does not perform an activity in the fragmentation.

P1005 / 00MX This prevents wear. In addition, this absence of material and the reduction of static pressures between the parts 16 and 19, are obtained thanks to the insulation provided by the hood 6, considerably reducing the mechanical stresses exerted on the cone 16, the latter being capable of vibrating, moving and / or rotate while undergoing minor forces. The cone 16 and the bell 6, in particular, as already mentioned above, are provided to be coaxial. With respect to the breaker 2, the latter includes, by way of example, a frame 20 having a vibrating ring 19 provided, at least partially, facing the cone 16. The ring 19 is made to vibrate, in particular, by means of a vibratory device with unbalanced weights, not shown, which are mounted on the frame 20 and thus allow the material to be crushed once again against the cone 16. The ring 19 and the cone 16 are, in particular, coaxial and the cone 16 it is possibly free to rotate about its longitudinal axis and in this way facilitate the flow of material during the breaking operation. As already mentioned above, according to the different ways of exemplifying the illustrated embodiments, the end 18 of the cone 16 is provided P1005 / 00MX so that it emerges above the ring 19. According to a first form of the modality, the hood 6 protects the upper end 18, in particular, over the entire corresponding height of the cone 16, that is to say over the portion of the cone 16 located above the upper edge of the ring 19. According to other forms of the embodiment, the The bell 6 can also be of a shorter or longer length and, in the latter case, enters the breaking chamber 17. The bell 6 covers, at least partially, the emerging end 18 of the cone 16. The outer shell 3 rests, example, on the frame 20 in the area of the ring 19. If the external shell 3 is constituted, as is the possibility already mentioned above, by means of a ramp 12 and by an upper element 13, the ramp 12 is then secured, for example, to the frame 20, while the upper element 13 is suspended from the hopper 4. In this connection, in case the outer shell 3 is made of a single element, the external shell 3 is secured, directly or indirectly, to the breaker 2, mie while remaining free in relation to the hopper 4, under which it is arranged. These arrangements allow the breaker 2 and the hopper 4 to dissociate from one another and in this way limit the transfer of static charges.

P1005 / 00MX It should be noted that in order to be able to operate, if desired, using a wet process, the breaker according to the invention can include means for injecting a fluid, for example water in particular, into the break chamber 2 from the feeder device 1. The construction of the feeder device 2 in two parts, 12 and 13, makes this introduction and distribution of water even easier. The water can be injected, effectively, at the interface between the upper element 13 and the ramp 12. According to another form of the mode, arrangements can be made for the injection in the area of the bell 6, in the residual space 21. For for this purpose, the members of wing 11 have, for example, a thickness that enables the ducts to run through the bell 6. Having mentioned the above, according to a non-illustrated mode, arrangements can be made to secure the bell 6 to the frame 20. Other forms of the mode within the skill of the person skilled in the art may be contemplated without thereby departing from the scope of the present invention.
