ES1158785U - Block tire recycling mill (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Recycling model of block tires, of the type used to grind out-of-use tires, characterized in that it has two rotating anti-rotating blades with rectangular blades, to which four grooves are made in the lower part (two on each side of the blade), of sufficient size to accommodate the tabs of a height greater than 5 mm., which incorporate the armor plates, so that the tabs of the armor plates are inserted into the slots of the blades, being held by the blade itself without any other type of restraint.

DESCRIPTION

Block tire recycling mill.

Technology 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 constitutes the first step in obtaining a new product and its reuse. 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, these suffer a lot of wear and tear, there are a number of elements that must be changed periodically to be able 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 art

Publication referring to a cutting unit for double-shaft and slow speed shredders, Publication number ES2283177 A1 () Application number P200500472 (2-032005) Applicant: IMABE IBERICA SA (ES) The cutting system referred to in this patent It is different from our utility model.

Publication concerning a tire recycling mill that does not use a block, in our case the rotor is attached to the block with two centering bolts and a central screw, publication number ES1149458U (), Application number U201531309 (), Applicant: Astry-Quark , SL

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, placed on the sides of a block that you see is placed on the rotors.

Blades and blocks are an element of wear that changes periodically.

The lateral areas of the rotor where the block or support of the blades is supported, are protected by two armor plates, one right and one left, placed laterally on both sides of the block and held together by two keys.

The keys are placed horizontally by holding the two armor plates above the block, which has grooves to accommodate the keys and hold the blades located vertically, this block is attached to the rotor by means of two centering bolts and a central screw

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

Brief description of the drawings

Figure 1 shows a side view of the set of elements that accompany the assembly of the blades of grinding mills of tires out of use, currently used, consisting of:

1 - Right blade (A1)

2 - Keys (B1)

3 - Block (C1)

4 - Right armor plates (D1)

5 - Assembly

6 - Left blade

7 - Keys

9 - Block

10 - Left armor plate

Figure 2 shows a side view of the set of elements that accompany the assembly of the blades of crusher mills of modified out-of-use tires and in which the need for the use of the keys and that consist of:

1 - Interchangeable right blade (A2)

2 - Block (C2)

3 - Right armor plate (D2)

4 - Assembly

5 - Interchangeable left blade

6 - Block

7 - Left armor plate Preferred embodiment of the invention

5 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 grooves 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 flanges so that the blades directly hold the armor plates that are embedded in the grooves of the blades

Claims (2)

1. Recycling model of block tires, of the type used to crush out-of-use tires, characterized in that it has two rotors against rotating with some 5 rectangular blades, which are made four grooves in the bottom (two on each side of the blade), of sufficient size to accommodate the lashes of a height greater than 5 mm., Which incorporate the plates of shielding, so that the flanges of the shield plates are inserted into the slits of the blades, being held by the blade itself without the need for any other type of fastening. 10 2. A pneumatic block recycling mill, according to claim 1, characterized in that the blades are incorporated horizontally into the rotor, are positioned horizontally above the block and fastened by means of three screws to said block. 15 3. Block tire recycling mill, according to previous claims, characterized in that the blades are interchangeable.
