High flow low pressure suction device

A high flow low pressure suction device, wherein

• sucking fan(s) or rotating impeller(s) attached with a base plate, facing towards a vacuum chamber formed interior of the base plate sucks air or fluid or slurries from the environment through the perimeter of the device, where the interior geometrical design of the base plate by way of three subdivided flow sections comprises acceleration zone, turbulence zone and smooth zone;
• wherein the air or fluid or slurries from the perimeter of the device enters straight into the acceleration zone where the air or fluid or slurries is accelerated and then goes to the turbulence zone wherein the air or fluid or slurries experiences a sharp drop in pressure owning to the huge amount of energy loss due to turbulence created in zone and then after the air or fluid or slurries continues into the smooth zone wherein by the help of a flow diverter present at the center of the smooth zone which need not touch the sucked surface, diverts and controls flow and enables a constant cross section condition throughout the flow path faced by the air or fluid or slurries and wherein the smooth zone maintains the pressure over a large bottom area surface structure and finally the flow is sucked by the fan(s) and exhausted back into the surroundings (or the sump);
• thereby the device creates suction and sucks the surface;
• wherein the suction device does not need to contact the sucked surface.

A high flow low pressure suction device, wherein

• sucking fan(s) or rotating impeller(s) attached with a base plate, facing towards a vacuum chamber formed interior of the base plate sucks air or fluid or slurries from the environment through the perimeter of the device, where the interior geometrical design of the base plate by way of two subdivided flow sections comprises turbulence zone and smooth zone;
• wherein the air or fluid or slurries from the perimeter of the device enters directly into the turbulence zone which accelerates and creates turbulence to the air or fluid or slurries and experiences a sharp drop in pressure owning to the huge amount of energy loss due to turbulence created in zone and then after the air or fluid or slurries continues into the smooth zone wherein by the help of a flow diverter present at the center the smooth zone which need not touch the sucked surface, diverts and controls the flow and enables a constant cross section condition throughout the flow path faced by the air or fluid or slurries and wherein the smooth zone is designed so to keep the turbulence to a minimum and maintains the pressure over a large bottom area surface structure;
• and finally the flow is sucked by the fan(s) and exhausted back into the surroundings (or the sump);
• thereby the device creates suction and sucks the surface;
• wherein the suction device does not need to contact the sucked surface.

• sucking fan(s) or rotating impeller(s) attached with a base plate, facing towards a vacuum chamber formed interior of the base plate sucks air or fluid or slurries from the environment through the perimeter of the device, where the interior geometrical design of the base plate by way of four subdivided flow sections comprises two acceleration zones, one turbulence zone and one smooth zone;
• wherein the air or fluid or slurries from the perimeter of the device enters straight into the first acceleration zone where the air or fluid or slurries is accelerated and then goes to the turbulence zone wherein the air or fluid or slurries experiences a sharp drop in pressure owning to the huge amount of energy loss due to turbulence created in zone then again flows into a second acceleration zone and then after the air or fluid or slurries continues into the smooth zone, wherein by the help of a flow diverter present at the center of the smooth zone which need not touch the sucked surface, diverts and controls flow and enables a constant cross section condition throughout the flow path faced by the air or fluid or slurries and wherein the smooth zone maintains the pressure over a large bottom area surface structure and finally the flow is sucked by the fan(s) and exhausted back into the surroundings (or the sump);
