Description

The utility model relates to devices for collapsing bulk material vaults in bunkers and silos.

A device for collapse of the arch of bulk material is known, containing a nozzle with a curved tip, made with the possibility of rotation around the axis of the nozzle (SU No. 330091, B65G 65/72, publ. 24.11.1972).

A device for collapsing arches of bulk material in bunkers is known, containing a hollow body with nozzles installed on its surface, which can rotate around its axis from the torque generated by the air flowing from the nozzles (SU No. 1454758, B65D 88/70, publ. 30.01.1989 ).

The disadvantage of these devices is the lack of efficiency, since the shape of the gas jet does not ensure the impact of the outgoing gaseous medium on a sufficient volume of bulk material.

The closest technical solution to the claimed utility model is a high-pressure valve for supplying repetitive pulses of a compressed gaseous medium, containing a movable piston element having a structure movably engaged with the central channel in the housing, the piston element having an enlarged end of the head sealing the front end of the channel (US No. 6237893, F16K 15/06, F16K 1/36, published 05/29/2001).

The disadvantage of this device is the lack of efficiency due to the area of the gas jet, limited by the expanding shape of the piston element.

The objective of the utility model is to increase the efficiency of the device for collapsing bulk material vaults by increasing the zone of impact of the gas jet.

The technical result is achieved by the fact that the device for collapsing the arch of bulk material contains a housing, a spring installed in the housing, an electromagnetic valve, a rotor, the cavity of which has the shape of a Laval nozzle, having holes, the axis of which is located at an angle of not more than 67 degrees to the tangent to the surface of the rotor, covered and held inside the housing by a spring, a nipple installed between the solenoid valve and the housing, a polyamide ring enclosing the rotor in front of the housing in front of the spring.

The essence of the device for the collapse of the arch of bulk material is illustrated by the drawing.

The device for collapse of the arch of bulk material contains a housing 1, in which a rotor 2 is installed, the internal cavity of which has the form of a Laval nozzle, having holes 3, the axis of which is located at an angle of not more than 67 degrees to the tangent to the surface of the rotor 2 (determined by calculation), held in the housing 1 by a spring 4, and the housing 1 communicates with a source of compressed gas medium (not shown in the drawing), supplied through the solenoid valve 5, through the nipple 6, and to reduce friction, a polyamide ring 7 is installed in the housing 1, and the device itself is mounted in the hole , drilled in the wall of the hopper 8, and is held in the wall by an adjusting ring 9, which is fixed on the outer surface of the housing with three set screws 10.

The device for the collapse of the arch of bulk material works as follows.

When the solenoid valve 5 is opened, the compressed gaseous medium enters the body 1 through the nipple 6 and begins to fill the rotor 2, compressing and accelerating as it passes through the internal cavity in the form of a Laval nozzle. Gradually, as the compression force of the spring 4 is overcome, the rotor 2 moves out of the body 1, and the gas flow begins to exit through the holes 3, creating a torque, since the axes of the holes 3 do not intersect the axis of the rotor 2, and spinning the rotor 2. high speed from the holes 3 gas flows destroys the arch of bulk material and resume the process of its expiration.

When the solenoid valve 5 is closed, the gas medium ceases to enter the housing 1, and the rotor 2 moves inside the housing 1 due to the increase in the resistance force of the spring 4.

Compared with the prototype, this device for the collapse of the arch of bulk material is more efficient, since the retractable and rotating rotor provides the effect of the released gaseous medium on a larger volume of bulk material.
