Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example 1: a magnetic suspension rotary grating as shown in fig. 1, which comprises a grating roller 6 and a base 8, wherein the grating roller 6 is connected above the base 8 through a magnetic suspension module 4 in a non-contact way;
the magnetic suspension modules 4 are arranged on the outer walls of the two ends of the grid roller 6 and are matched with the two ends of the base 8;
the one end of grid cylinder 6 is opened there is sewage water inlet 1, be equipped with row's sediment flight 5 along its length direction in the grid cylinder 6, the length of the length grid cylinder 6 of base 8 is the same, and passes through connecting rod fixed connection in base 8 below of sewage water inlet 1, be equipped with hourglass hopper-shaped delivery port 7 on the base 8.
The other end that sewage water inlet 1 was kept away from to grid cylinder 6 is opened there is slag notch 9, the one end that grid cylinder 6 is the same with sewage water inlet 1 is opened there is the high pressure and is washed the water inlet, the inside water drive impeller 3 that is equipped with of grid cylinder 6, water drive impeller 3 locates the one end that grid cylinder 6 is close to sewage water inlet 1, the outer peripheral face of water drive impeller 3 is fixed in the inner wall of grid cylinder 6, row's sediment spiral and base 8 are 340 or 316L stainless steel.
When the invention is carried out specifically, because the roller is not contacted with the base 8, the invention avoids the easy damage problem of the prior roller connecting part with the motor when the roller rotates.
Wherein, high pressure wash water inlet 2 connects high pressure water pipe reinforcing hydraulic drive to the mobility that relies on water drives the rotation of the hydraulic drive impeller 3 in the grid cylinder 6 and drives the grid cylinder 6 rotatory simultaneously, and row's sediment flight 5 and grid cylinder 6 syntropy rotation simultaneously in the grid cylinder 6, sewage passes through the delivery port 7 through the filtration of grid cylinder 6 and discharges, and the solid that is greater than the 6 clearances of grid cylinder is intercepted and is collected to slag notch 9 discharge through row's sediment flight 5 rotation in the cylinder.
The sewage is delivered to the equipment by a lift pump through a sewage pipe network, the pipe network is butted with the equipment by a flange, and a water inlet pipeline of the equipment area is supported by a pipeline and fixed on an equipment platform by an anchor ear. The pipeline entering the interior of the grating roller 6 is designed into a vortex pipeline, and the water outlet is aligned with the water retaining blade.
The high-pressure washing part adopts a high-pressure pump to collect water, two rows of high-pressure nozzles can be arranged on two sides of the grid roller to wash the grid roller 6 from outside to inside, and solid blocked in the gaps of the grid roller 6 is washed away to ensure the water passing performance of the filter screen.
Two ends of the grid roller 6 are designed with the ring guide type magnetic suspension module 4, so that the grid roller 6 can hover in the magnetic force central space. The mode that the impact nature of water drives water conservancy drive impeller 3 drive grid cylinder 6 in the grid cylinder has evaded traditional motor drive or shaft drive, uses the design of bearing tug. The whole set of equipment has no vulnerable parts (bearing, transmission device, speed reducer, etc.)
The invention can efficiently intercept solids with the diameter of more than 0.5 mm, effectively reduce the processing load of the post-process section, reduce the damage of the solids to the post-process section equipment and greatly reduce the maintenance cost.
In this embodiment, the sewage water inlet 1 is equipped with the bearing in the junction of locating grid cylinder 6, reduces frictional force.
Having thus described the basic principles and principal features of the invention, it will be appreciated by those skilled in the art that the invention is not limited by the embodiments described above, which are given by way of illustration only, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
