Abstract

The invention relates to the block diagrams. A device has means for trimming of the boards of tires, means for supplying the tires with cut off boards for destruction, a destructor of tires in the form of surge gap on the basis of capacitors.

Description

The second, additional to the first, difference lies in the fact that the central rod is equipped with a support platform on one side, on which a dielectric gasket and one of the fasteners are laid, and is rigidly fixed in a fixed base, and on the other side! kinematically connected with the second latch. Such a form of mounting of the central rod and its interconnections with the other parts of the axisymmetric means of connecting the destructible busbars to the impulse arrester facilitates loading of busbars and the reliability of their retention during the discharge of capacitors.

The third, additional to the second, difference consists in the fact that the central rod and the second retainer are filled in the form of "screw-nut" pairs, which allows the tire to be destroyed! of different sizes, adjusting the contact force between the cut edges of the tires and the fasteners depending on the stiffness of the tires.

The fourth, additional to the second, difference consists in the fact that the central rod in the middle part is equipped with a stop, and the second retainer is built in the form of a collapsible coupling. This form of execution is preferable for the ongoing destruction of tires of the same standard size.

The fifth additional difference is that the additional current-conducting protrusion is filled in the form of a peripheral ring, which makes it possible to significantly simplify the means of protecting the zone of tire destruction.

The sixth, additional to the fifth, difference is that the peripheral ring is filled as the side wall of the "bottom-lid" part, consisting of two parts arranged one above the other with annular inner edges, which essentially turns that part of the device into a protective chamber.

The seventh additional difference, aimed at solving the problem in its second part, consists in the fact that the device for electric discharge destruction of tires with a metal cord is equipped with a device for the destruction of side rings, which has an inductor, a connection to a pulse arrester, a bed for laying pre-cut sides and clamp, installed with the possibility of reciprocating and forward movement. At the same time, full electric discharge destruction of the tires is ensured.

The eighth, additional to the seventh, difference lies in the fact that the device for destroying side rings is equipped with a second inductor, which is also connected to a pulse discharger, which facilitates the destruction of side rings with the remains of cord wires.

The proposed device for the destruction of worn tires with a metal cord generally has the following main parts (see Fig. 1): arbitrary design mechanism 1 for cutting flat tires, which can be completed, for example, in the form of two or more commercially available milling heads, and which provides access to the ends of most of the cord wires in the bus breaker; tayuke arbitrary design mechanism 2 for feeding cut tires to destruction, implemented taking into account the dimensions and mass of the tires, for example, in the form of a commercially available belt or walking conveyor and/or automatic manipulator; destructor Z on the basis of a pulse arrester 4 and an axisymmetric device 5 for predominantly galvanic connection of that arrester 4 to a metal cord; a remote control panel for obtaining data on the state of the destructor Z and transmitting control information to it; an arbitrary design tool 7 for the removal of tire destruction products from the working zone, which can contain, for example, a mechanical conveyor for feeding pieces of metal-free rubber! for further grinding, the pneumatic transporter of metal particles is not indicated in the collector.

At the outlet of the device for destruction of worn tires, it is expedient to install means 8 for crushing and grinding rubber. Similar to the equipment used for the production of rubber crumb from tires with a textile cord, it can include: a commercially available mechanical crusher, at least one mechanical mill (respectively for preliminary crushing and further grinding of pieces of rubber into crumbs of the required size) and a set of sieves.

The impulse discharger 4 (see Fig. 2) is made on the basis of at least one, and preferably several, identical high-voltage capacitor modules 9 for the accumulation of electric charges and their simultaneous impulse discharge on the metal cord of the destructible tires. The discharger 4 is equipped with: a power supply unit 10 for charging high-voltage capacitor modules 9, which generally includes a transformer and a rectifier; block 11 protection! of high-voltage equipment against sparks and possible short-circuits in electrical circuits, which, in a manner known to specialists, provides control of serviceability and disconnection of malfunctioning high-voltage components and signaling, and block 12 of synchronous ignition of high-voltage capacitor modules 9, which, as a rule, is equipped with a generator of single high-voltage low-current pulses connected to the control inputs of standard electronic dischargers of all high-voltage capacitor modules 9.

Each module 9 (see fig. 3) has at least one, as is well known to the specialist and therefore not designated by a person in the drawings, but preferably several high-voltage capacitors connected in parallel and a standard electronic discharger for their connection through the indicated means of 5 Kk metal cord of destructible tires.

Axisymmetric device 5 for galvanic connection of high-voltage capacitor modules 9 to metal cord (see fig. 4 and 5) regardless of form! The filling has two conductive retainers 13 and 14 with working surfaces in the form of truncated cones and an additional conductive protrusion 15, which is located coaxially in both directions of the retainers 13 and 14, galvanically connected to one of them and electrically isolated from the second by a dielectric gasket 16.

The first preferred form of implementation of the axisymmetric device b (see fig.4) has an additional current-conducting inlet 15 in the form of a central, predominantly cylindrical rod, the diameter of which should preferably allow the sliding fit of the destructuring tires along their inner diameter. Such a rod-protrusion 15 on the one hand is preferably provided with a steep support platform for placing on it a dielectric gasket 16 and a second retainer 14 placed on it and is rigidly fixed (for example, in a non-shown immovable body of a security camera), and on the other hand! during work! holds the first retainer 13.

For such retention, the retainer 13 and the rod-protrusion 15 can be filled! in different ways, for example, in the form of pairs! "screw-nut" (preferably with a stop thread), as conventionally shown in the drawing. Such a variant (not shown to the individual, but understandable to specialists) is also possible, in which the rod-prong 15 has a stop in the middle part in the form of several radial protuberances or a continuous annular edge, and the retainer 13 is filled in the form of a collapsible coupling, having at least two parts contacting the working position with the mentioned stop.

However, regardless of the form! the completion of the retainer 13 with the completion of the protrusion 15 in the form of a rod requires a protective chamber not shown.

The second preferred form of implementation of the axisymmetric means 5 (see Fig. 5) is equipped with an additional current conductor/m projection 15 in the form of a peripheral ring, the inner diameter of which preferably allows the sliding arrangement of destructible tires along the outer diameter. It is expedient that the peripheral ring-protrusion 15 was filled as the side wall of the "bottom-lid" pair, consisting of two parts of the same diameter, located one above the other, with annular inner edges and essentially a protective chamber.

For additional (along with electrical) synchronization of the operation of all high-voltage capacitor modules 9 and reduction of their total capacity, necessary for the destruction of tires of each specific size, it is advisable to observe the following conditions for their placement relative to the axisymmetric means 5: if the shape, overall size and relative arrangement of the means of maintenance and fencing destructor Z allows, zty modules 9 duties! the wires should be installed symmetrically at practically the same linear and angular distances from the protrusion 15, as shown in Fig. b, and all incoming electrical conductors should have as close as possible and as small as possible inductance values; with the imposed asymmetry of the installation of these modules 9 relative to the protrusion 15 (see Fig. 7), the leveling and minimization of the inductance values of the incoming electrical conductors may fail! changes in their sizes and/or shapes (for example, when strip lines are used for transmission of electrical energy, the increase in inductance when their length is increased can be compensated by a corresponding increase in their width).

It is expedient to supplement the described device with a device for destroying side rings, which generally has (see Fig. 8): an inductor 17, made, for example, in the form of one or more turns of a conductor connected to a pulse arrester 4, a housing 18 for laying side rings and movable clamp 19, installed, in particular, with the possibility of reciprocating movement.

In cases where there are remnants of the metal cord 20 in the cut-off sides of the tires, it is expedient to supplement the device for the destruction of side rings with a second inductor 21, which should also be connected to the pulse arrester 4 either directly or in parallel with the inductor 17, as shown in Fig.9.

The described device is used as follows.

Each next tire after trimming is fed by the on-board mechanism 1 by mechanism 2 to the destructor Z and fixed between the current-conducting clamps 13 and 14 of the axisymmetric device 5.

When using such a tool 5, as shown in Fig. 4, the tire is put on the conductive protrusion-rod up to the stop in the lower (stationary) conductive retainer 14, and then install (for example, screw in) the upper conductive retainer 13, clamping the edge cut and introducing the exposure at cut off the end! cord wires in galvanic contact with the pulse arrester 4. Similarly, when using the means 5 shown in Fig. 5, the bus is placed on the lower (stationary) conductive retainer 14 on the "bottom" of the lower part of the peripheral ring-entrance 15 and then its upper part is installed as a "lid", under the weight of which the clipped sides are clamped.

According to the commands from the remote control panel 6, the power supply unit 10 from the stationary electrical network or other source of electrical energy charges the entire capacitor! of high-voltage capacitor modules 9, and then block 12 synchronously ignites these modules 9. The current pulse passing through the core wires, which are in galvanic contact with the current-conducting clamps 13 and 14, generates eddy currents in those wires as well, ends! which remained unopened when trimming the sides.

At the same time, in almost all core wires, within a few milliseconds, heat is released so intensively along the boundaries of the crystalline grains of the metal that it explodes, and the formed small (generally powdery) particles tear the breaker and the busbar protector and, in the main, fly out of the channels formed in the rubber mainly as a result of its mechanical expansion and, to an insignificant degree, as a result of its burning on the surface of contact with the cord wires.

Due to the shortness of the current pulse and costs! most of the energy for the destruction of the metal cord mass of rubber! does not have time to warm up noticeably. Therefore, volatile toxic substances are practically not released from it, and the process turns out to be ecologically safe.

Regardless of whether the external (see Fig. 4) or internal (see Fig. 5) electrode of coaxial pairs! turns out to be a metal cord of a destructible busbar, an axisymmetric device 5 equipped with a protrusion 15 during the pulse discharge of high-voltage capacitor modules 9 ensures the opposite direction of currents in the metal cord and in the protrusion 5. This contributes, as already noted, to a decrease in the total electrical inductance of the specified device 5 and the metal cord, to a reduction in the duration of the electrical pulse and increasing amplitudes! and the current density in it and, secondly, the manifestation in the metal cord of destructible tires, as a result of "magnetic impact", the more powerful repulsive mechanical impulses, the higher the current amplitude in the destructuring electrical impulses.

Similarly, each cut side ring is placed in the housing 18, fixed with a clamp 19 and the inductor 17 is brought to it (as in Fig. 8) or - if there are remnants of cord wires in the ring - both inductors 17 and 21 (as in Fig. 9) and metal is extracted from rubber during pulse discharge of high-voltage capacitor modules 9 on inductors).

Product! destruction of tires is taken out of working areas! means 7, feeding pieces of metal-free rubber! into means 8 for its crushing and grinding, and metal particles - into the collector, after which the cycle of destruction is repeated.
