SUBMITTAL-SUN SUCTION UNIT

The proposed utility model relates to the field of municipal engineering, mainly to devices for cleaning debris from city roads and sidewalks.

A device is known for a vacuum machine designed for garbage collection, containing a fan, a hopper with a feed bin; a sleeve located in the upper part of the hopper, a baffle w, a drain (divider) mounted movably in a vertical plane in the upper part of the hopper opposite to the outlet pipe of the feeding sleeve , between the baffle plate and the outlet pipe, two reflectors (baffle plates) of the air flow with a curved surface in plan, a concave surface facing the baffle plate are rigidly attached to the side walls of the hopper , Vsholnennomu a triangular prism disposed symmetrically about the longitudinal axis of the outlet, wherein the baffle plate is pivotally mounted in a vertical plane and is spring-loaded relative to the plane of rotation of the hopper (AU № 1,276,737, 1985., EOSH).

The contaminants absorbed by the supply sleeve with the air flow enter the hopper through the outlet pipe. Getting on the baffle plate (divider), the air flow bifurcates and then, spinning, gets on the reflectors. The concave surface of the reflectors spins the air flow even more, which contributes to better separation of contaminants. Due to the fact that the shield is spring-loaded, the slope of the shield changes, and, consequently, the trajectory of the air flow deflected by the shield.

However, in the closest analogue, there is a counter direction of movement of the cleaned air stream and the air stream with garbage.

when air flows in contact, the efficiency of separation of debris decreases.

The purpose of the proposed device is to increase the efficiency of garbage separation due to the optimal organization of the movement of air flows in the hopper.

This goal is achieved due to the fact that in the sweeping suction unit, the fan and the hopper and intake connected in series with its suction cavity are connected through the supply sleeve to the hopper inlet, a divider made in the form of a trihedral prism, mounted inside the hopper in its upper part, opposite to the inlet symmetrically located to the inlet two baffle plates, rigidly fixed to the walls of the hopper, the divider is placed horizontally in a longitudinal vertical oskosti hopper with the location of one of the ribs of opposite inlet and to its beveled in a vertical transverse plane of the ends of the baffle plate is rigidly attached to form together with the side faces of the deflector and the walls of the hopper spatial guide surfaces forming the air flow inside the hopper.

This embodiment of the sweeping-suction unit provides the optimal organization of air flows, eliminating their oncoming direction of movement.

The sweeping suction unit and the organization of air flows in the hopper are shown in the figures:

-Fig. 1 - sweeping-suction unit, a longitudinal section;

-Fig. 2 - the movement of air flow in the longitudinal plane;

-Fig. 3 - the movement of air flows in the transverse plane. The unit includes an intake device 1 communicated by

supply sleeve 2 with an inlet 3 of the hopper 4, in the upper part of which an outlet 5 is made, closed by a grid 6, communicating the hopper 4 with the duct 7. The duct 7 communicates the hopper 4 with a suction

fan cavity 8 and beyond - with the atmosphere. In the upper part of the hopper 4 opposite to the inlet 3, a horizontally placed divider 9 is rigidly fixed, made in the form of a trihedral prism with ends beveled in the vertical transverse plane to which the baffle plates 10 are rigidly attached.

During operation of the unit, the fan 8 creates a vacuum in the hopper 4, due to which the estimate (garbage) from the swept surface along with the air is sucked through the intake device 1, enters the supply sleeve 2 and then through the inlet 3 into the hopper 4. Having a significant speed, the flow reaches the lateral faces of the divider 9, bifurcates and deviates by the lateral faces of the prism in opposite directions, and interacting with the baffle plates 10 and the walls of the hopper 4, it further twists with a change in the trajectory of motion relative to and bzshkera. The movement of air occurs along spatial curves formed by a combination of divider surfaces, baffle plates and hopper surfaces. Existing centrifugal forces remove debris to the periphery of the flows, and it falls to the bottom of the hopper 4. In addition, during movement in the hopper, the air flow loses speed and is freed from the estimate, which is deposited on the bottom of the hopper. The air freed from debris, through the outlet 6 with a mesh 7 enters the duct 5 and then into the fan 8, and then is discharged into the atmosphere. The grid 7, installed at the inlet to the outlet duct, delays the fraction of the estimate partially remaining in the air flows. The proposed organization of the movement of air flows eliminates the intersection of air flows with garbage at the entrance to the hopper and air flows exempted from the estimate at the exit of the hopper, providing a more complete deposition of garbage to the bottom of the hopper.
