La presente invención se refiere a una máquina que ha sido especialmente concebida para llevar a cabo el pre-tratamiento de los rechazos de las plantas de residuos sólidos urbanos, con el fin de preparar estos rechazos y poder convertirlos en combustible derivado de residuos. The present invention relates to a machine that has been specially designed to carry out the pre-treatment of rejections of urban solid waste plants, in order to prepare these rejections and convert them into fuel derived from waste.
Así pues, la máquina que se preconiza está destinada a formar parte de una planta de fragmentado de rechazo para biomasa, sustituyendo a los clásicos molinos trituradores. Thus, the machine that is recommended is destined to be part of a fragmented rejection plant for biomass, replacing the classic crushing mills.
Tal como acaba de decirse, hasta la fecha el pre-tratamiento de los rechazos de residuos urbanos se lleva a cabo con la colaboración de molinos trituradores que independientemente de sus diseños específicos presentan como denominador común la siguiente problemática: As it has just been said, to date the pre-treatment of urban waste rejections is carried out with the collaboration of crushing mills that, independently of their specific designs, present the following problem as a common denominator:
La entrada de objetos duros, como barras de acero, piedras, etc., produce la rotura de las cuchillas de corte. The entry of hard objects, such as steel bars, stones, etc., causes breakage of the cutting blades.
La entrada de objetos de naturaleza textil y similar, tales The entry of objects of a textile and similar nature, such
como moquetas, sacos textiles, etc., provoca atasco y such as carpets, textile bags, etc., causes jam and
parada de los molinos. mills stop.
Se reqUIere una potencia eléctrica instalada muy considerable, con el consecuente consumo energético también alto. A very large installed electrical power is required, with the consequent high energy consumption.
No extraen la humedad de los rechazos. They do not extract moisture from rejections.
Determinadas partes del molino están sometidas a grandes desgastes, lo que supone un mantenimiento de los mismos importante. Certain parts of the mill are subject to great wear, which is important maintenance.
La máquina que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en todos y cada uno de los diferentes aspectos comentados. The machine that the invention proposes solves in a fully satisfactory way the problem described above, in each and every one of the different aspects mentioned.
Para ello y de forma mas concreta dicha máquina está constituida mediante la combinación funcional de una prensa y una cizalla, de manera que el prensado de los residuos trae consigo un doble efecto, por un lado una compactación de los mismos, y por otro una sustancial eliminación de la humedad existente en ellos. For this, and more specifically, said machine is constituted by the functional combination of a press and a shear, so that the pressing of the waste brings with it a double effect, on the one hand a compaction of the same, and on the other a substantial elimination of moisture in them.
De forma mas concreta la prensa de compactación, que recibe los residuos a través de una tolva superior, genera con los mismos un prisma contiguo de sección rectangular, que se desplaza de forma también continua hacia la zona de corte de la máquina, donde dicho pnsma es cortado determinando tramos de longitud predeterminada y ajustable en función de las exigencias especificas de cada caso. More specifically, the compaction press, which receives the waste through an upper hopper, generates with them an adjacent prism of rectangular section, which also moves continuously towards the cutting area of the machine, where said pnsma It is cut by determining sections of predetermined length and adjustable according to the specific requirements of each case.
De forma mas concreta bajo la citada tolva se establece un túnel sobre el que desemboca la misma y en el que juega un pistón accionado por al menos un cilindro hidráulico, pistón que cumple su función prensora mas allá de la citada tolva, en un sector del túnel provisto de ranuras para drenaje de la humedad, rematándose dicho túnel en una zona de corte donde se establecen cuchillas de corte fijas y cuchillas de corte móviles, éstas ultimas accionadas por al menos también un cilindro hidráulico, situándose a la salida de la zona de corte una cortina de seguridad, basculante, que impide el acceso manual a la zona de corte. More specifically under the said hopper a tunnel is established on which it flows and in which a piston operated by at least one hydraulic cylinder plays, a piston that fulfills its pressing function beyond the said hopper, in a sector of the tunnel provided with slots for moisture drainage, said tunnel being finished off in a cutting area where fixed cutting blades and mobile cutting blades are established, the latter driven by at least one hydraulic cylinder, located at the exit of the zone of cut a safety curtain, tilting, which prevents manual access to the cutting area.

A la vista de las figuras reseñadas puede observarse como la máquina que la invención propone está constituida a partir de un túnel (1) preferentemente de sección rectangular, que adopta una disposición horizontal y que descansa sobre el suelo o cualquier superficie de sustentación a través de patas (2), adecuadamente distribuidas. In view of the aforementioned figures it can be seen how the machine that the invention proposes is constituted from a tunnel (1) preferably of rectangular section, which adopts a horizontal arrangement and that rests on the ground or any bearing surface through legs (2), properly distributed.
Este túnel (1), abierto por ambos extremos, presenta también una abertura superior (3) a través de la que desemboca en su seno una tolva (4) sobre la que se depositan los rechazos de los residuos sólidos urbanos, por ejemplo con la colaboración de un transportador de lamas metálicas, no representado. This tunnel (1), opened at both ends, also has an upper opening (3) through which a hopper (4) flows into it, on which the rejections of urban solid waste are deposited, for example with the collaboration of a conveyor of metal slats, not shown.
En el túnel (1) juega un pistón (5) solidarizado al vástago (6) de un cilindro hidráulico (7), pistón que queda integrado en un carro de prensado (8), deslizante a lo largo del túnel (1) desde una posición anterior a la tolva (4), la representada en la figura 3, hasta una posición en la que sobrepasa dicha tolva. In the tunnel (1) a piston (5) plays in solidarity with the rod (6) of a hydraulic cylinder (7), a piston that is integrated in a pressing carriage (8), sliding along the tunnel (1) from a previous position to the hopper (4), the one represented in figure 3, to a position in which said hopper exceeds.
El pistón (5) está dotado de una cuchilla (9) que se desplaza con el mismo, cuya evidente finalidad es seccionar la masa de residuos a nivel de la embocadura (3) de comunicación con la tolva, colaborando con dicha cuchilla móvil (9) una cuchilla fija (10) situada sobre un puente de corte (11) establecido a continuación de la tolva (4). The piston (5) is provided with a blade (9) that moves with it, whose obvious purpose is to section the mass of waste at the level of the mouth (3) of communication with the hopper, collaborating with said mobile blade (9 ) a fixed blade (10) located on a cutting bridge (11) established after the hopper (4).
El sector terminal del túnel (1) está provisto de ranuras laterales (12) para drenaje de la humedad de que pueden ser portadores los residuos, y dicho túnel se remata en unas mordazas fijas (13) accionadas por un cilindro (14), cuya finalidad es la de inmovilizar el bloque de residuos durante la fase de corte de los mismos. The terminal sector of the tunnel (1) is provided with lateral grooves (12) for draining moisture from which the waste can be carriers, and said tunnel is finished off in fixed jaws (13) actuated by a cylinder (14), whose The purpose is to immobilize the waste block during its cutting phase.
Dicha fase de corte se lleva a cabo con la colaboración de un cabezal de corte (15), que en el ejemplo de realización practica elegido está provisto de una pareja de cilindros de corte (16), con respectivas cuchillas móviles (17) montadas sobre vástagos de dichos cilindros (16), cuchillas (17) con las que colaboran otras cuchillas fijas (18) establecidas en la cara inferior del citado cabezal de corte (15). Said cutting phase is carried out in collaboration with a cutting head (15), which in the example of practical embodiment chosen is provided with a pair of cutting cylinders (16), with respective movable blades (17) mounted on rods of said cylinders (16), blades (17) with which other fixed blades (18) established on the underside of said cutting head (15) collaborate.
