Abstract

Recycling tire mill, of the type used to crush the tire out of use, characterized because it has two rotating rotating blades with rectangular blades, which are made four slits in the bottom ( two on each side of the blade), of sufficient size to accommodate the tabs of the armor plates and armor plates to which are incorporated two tabs of a height greater than 5 mm., so that the tabs of the armor plates are inserted into the slits of the blades, being held by the blade itself without the need for any other fastening element.

Tire recycling mill.

TECHNICAL SECTOR

Under Royal Decree 1619/2005 on the management of tires whose main purpose is to prevent the generation of tires out of use, these are collected and crushed for reuse.

The products from these crushes have numerous applications such as energy valorization, asphalt modifications, manufacture of tiles for playgrounds, manufacture of artificial grass, shoe soles, among others.

The crushing of these tires is the first step in obtaining a new product and reusing it. This is carried out in some mills where the whole tire enters and is cut into small pieces of different sizes.

These mills are composed of a cutting chamber consisting of two wheels or rotors against rotating. On these wheels are placed blades that make scissors effect cut the tires.

When introducing the tires used in the rotors, they suffer a lot of wear, so there are a number of elements that must be changed periodically to ensure the quality of the product in terms of cutting and at the same time avoid excessive wear of the rotors. In this type of mills the elements that are changed periodically are: the blades element that makes the cut, the armor plates that protect the rotors and the keys that hold the armor plates.

STATE OF THE TECHNIQUE

There is a publication referring to a cutting unit for double-shaft and slow-speed shredders, Publication number ES2283177 A1 () Application number P200500472 () Applicant: IMABE IBERICA SA (ES) The cutting system referred to in this patent is different from our utility model.

EXPLANATION OF THE INVENTION

The cutting chamber of the tire recycling crushers that occupy us, consists of two rotors or counter-rotating wheels with blades made of steel.

The blades are an element of wear that changes periodically.

The lateral areas of the rotor where the blade or blade supports are supported, are protected by two armor plates, one right and one left, which in turn are held together by two keys. Thus, the armor plates are placed laterally on both sides of the blade holder, the keys are placed on the top horizontally holding the two plates and above these the blade is also placed horizontally that is held to the blade holder with three screws.

The invention consists in modifying the design of the blades and the armor plates so that the use of the keys is not required.

The blades are manufactured in mechanized, tempered, tempered and ground grinding powder-coated steel. The armor plates are made of anti wear steel and laser cut.

Four slits have been made in the lower part of the two blades on each side and the design of the armor plates has been modified by adding two tabs so that the blades directly hold the armor plates that are embedded in the grooves of the blades .

Claims (1)

1. Tire recycling mill, of the type used to crush the tire out of use, characterized in that it has two rotors against rotating with blades in 5 rectangular shape, which are made four grooves in the bottom (two on each side of the blade), of sufficient size to accommodate the flanges of the armor plates and armor plates to which two flanges of a height greater than 5 mm are incorporated, so that the flanges of the armor plates are introduced into the slits of the blades, being held by the blade itself without the need for any other element of fastening.
