Detailed Description of the Invention:
The present invention is mainly focused on reducing the human intervention to maximum extent in the process of collecting dry waste and use a simple machine which is not complex in design and can be easily operated. The invention mainly includes an electric motor, a collecting bin, a suction pipe, a suction nozzle mounted to the bin which is attachable and detachable, a handle, wheels attached to the bin. The basic process involved in our invention is, an electric motor is used which create suction pressure, this electric motor is enclosed inside a bin which is sealed thus vacuum losses are reduced. A suction pipe is attached to bin, this suction pipe collects the dry waste in the bin. Electric motor converts electrical energy to mechanical energy.
The proposed vacuum street cleaner consists of an electric motor which is operated at 230vs. The vacuum cleaner consists of 2000WATTS, 2.5HP suction motor and 47 liters dust collecting chamber. As the motor spins the driveshaft, the driveshaft subsequently rotates the impeller (a small disc resembling a fan) at high speeds, typically ranging from 13000 RPM. An impeller is used to generate suction. An impeller consists of a circular plastic base containing a series of fan blades stemming from the middle and receding outward towards the edge. A small hole is cut in the center of the impeller to allow for the driveshaft to connect it the motor. The main function of the impeller is to provide suction to the vacuum. In this vacuum street cleaner, air is pulled through the chamber of dust collector towards the vacuum conveying pump at high speed, it spins in cyclonic motion. The centrifugal force created by this fast, circular air flow drives the heavier particles, fines and dust outward towards the wall of cyclone chamber. They hit the wall lose velocity and fall down into the collector tank. And also, it consists of air filter and it is be positioned before the fan, so the air is filtered as soon as it enters the vacuum
The electrical motor (3) which works on 230 V AC(alternating current) power supply. It has the power of 2.5hp. it operates up-to 13000 rpm. It is very high-speed motor which spins in cyclic motion the centrifugal force created by this fast, circular air flow drives the heavier particles and dust outward towards the wall of cyclone chamber. They hit the wall and losses the velocity and fall down into the collecting bin. The Impeller is used to generate suction which is attached to the suction motor. This impeller is made of hard plastic which can operates up-to 29000 rpm.
Air filter which prevents the dust from being spread around the room. In addition, the vacuum motor can become overheated if the dust particles are not filtered out and make their way into the motor. The main purpose of air filter is, filtering the air as it passes through the vacuum prevents fine dirt and dust particles from getting into the motor and building up over time. If a vacuum motor becomes gummed up or clogged with dust, your run the risk of experiencing dangerous and expensive mechanical failures.
The Foam Board (7) on which the motor is installed inside the bin. The foam board is placed in the bin with the support of L-clamps which are screwed to the walls of the bin. And this board plays a key role in creating the vacuum inside the bin by closing the boundaries all the sides of the beside the motor and walls of the bin. And the whole contacting part of board and the bin is sealed with a vacuum sealing tape in order to prevent the vacuum created inside the bin without escaping through the tiny openings.
The collecting bin (1) is made of aristo-plastic. Thickness of the bin is 3mm. wheels are mounted to bin in order to ensure the free movement while operating. A handle is also mounted on the bin to guide the movement while operating. The capacity of the bin is 47ltrs. The motor is fitted to the bin which is sealed to reduce the vacuum losses. The suction pipe and suction nozzle are attached to the bin, the dry waste is collected through the pipe and drops into the bin. The suction nozzle (6) is mounted to the base of the bin. The diameter of the suction nozzle is 25mm. This suction nozzle will suck the waste particles directly into the bin while the bin is moving on through it. A brush present behind the nozzle hole helps to collect the waste particles towards the center to simplify the suction.
The suction pipe (4) is attached to the face of the bin just a distance of 100mm above the suction nozzle. The diameter of the suction pipe is 50.8mm(i.e., 2inch). This suction pipe should be handled manually. The pipe should be moved close to the waste particles which are needed to be collected into the bin. The sucked waste particles will be directly collected into the bin. The length of the pipe is 1.5meters . Both the suction nozzle and suction pipe are attachable and detachable. The cap (2) is used to close the bin and cover the motor when not used and a handle is used to guide the movement of the machine.
