Fig. 2 is a top view of an embodiment of the silt separator with adjustable rotating flow rate of the present invention.
in the figure: 1. a cross beam; 2. separating the equipment body wall; 3. a water inlet; 4. a water outlet; 5. a rotary drum; 5.1, a drum rotating shaft; 5.2, a cylinder bracket; 6. a variable speed motor; 7. a rotating flow; 8. turbulent flow; 9. a conical hopper; 10. silt pipeline.
Detailed Description
The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the bottom of the silt separation equipment with adjustable rotating flow rate is a cone which gradually shrinks to form a cone-shaped mud bucket, the bottom end of the cone-shaped mud bucket is connected with a silt pipeline, as for the arrangement of a water inlet and a water outlet, a water inlet is arranged on one side of the upper end of the silt separation equipment in the embodiment, and a water outlet is arranged on the other side of the upper end, so that the water inlet direction is parallel to the water outlet direction, and the connection line of the water inlet and the water outlet passes through the central position of the silt separation equipment. In other embodiments, silt separation equipment's cross section also can set up to other shapes, for example circular, rectangle etc. the setting of delivery port and water inlet also is not restricted to in silt separation equipment's both sides, also can all set up in silt separation equipment's homonymy, for example only need when local formation whirl in equipment, can corresponding adjustment water inlet and delivery port's position, only need make it all be located the tangential direction of whirl can.
Be equipped with the crossbeam at silt splitter's top, the crossbeam on be fixed with actuating mechanism through bolted connection, welding or other well-known connected modes, actuating mechanism preferably adopts variable speed motor, variable speed motor can set up in the central authorities of crossbeam and also can set up in one side of crossbeam, variable speed motor's output shaft passes through gear or drive belt or other well-known transmission structure and a support cooperation is connected and can drive a support rotation, a support downside fixedly connected with section of thick bamboo pivot, a section of thick bamboo pivot be connected with a revolving drum, under variable speed motor's drive, a section of thick bamboo support can drive a section of thick bamboo pivot and rotate with a revolving drum that a section of thick bamboo pivot is connected. The inner diameter of the rotary cylinder can be set to be the same from top to bottom or gradually reduced from top to bottom, and when the inner diameter of the rotary cylinder is set to be gradually reduced from top to bottom, the flow velocity is increased and the pressure intensity is reduced due to the fact that the inner diameters of the rotary cylinders are different, and therefore the turbulent flow velocity is enhanced. Preferably, in this embodiment, the drum support includes two supports arranged in a cross manner, and two ends of the supports are respectively welded to the top end of the rotary drum.
When the silt separation equipment operates, inflow water containing silt flows in from the water inlet and forms a rotational flow, a turbulent flow which is upward from the inner side of the rotational cylinder and downward from the outer side of the rotational cylinder is formed by rotating the rotational cylinder, and the silt is accelerated to be accumulated at the conical hopper below the rotational cylinder under the combined action of the rotational flow and the turbulent flow. The silt gathered to the conical hopper is pressed out through a silt pipeline by a water head difference or pumped out of the separation equipment by a pump to be treated next, the water after silt separation is discharged from a water outlet, and the water outlet can be provided with the pumping equipment.
In a preferred embodiment, the variable speed motor is capable of being intermittently turned on and off, i.e. in use, the variable speed motor is controlled to run at a predetermined speed in response to the particle size of the silt, and then the motor is turned off to allow the silt to settle in the conical hopper for a suitable period of time, and the silt is removed. And after the sedimentation, restarting the motor and repeating the steps.
