The sieve pores of the upper sieve mesh and the lower sieve mesh are all taper holes with large upper parts and small lower parts; effectively prevent the sieve pores from being blocked.

The aperture and the hole spacing of the sieve holes of the upper sieve are smaller than those of the lower sieve; the secondary filtration of the effluent can be realized.

A water flow impact-proof plate is arranged in the cylinder body at the corresponding position of the water outlet end of the water inlet pipe; avoid intaking to cause direct impact to the barrel inner wall, can prolong the life of barrel.

The water outlet pipe is connected with the cylinder body through a flange; the screen can be replaced by disassembling the flange, the operation is simple, the maintenance is convenient, and the service life of the device is prolonged.

The water inlet pipe and the flushing pipe are connected to a clean water pipeline of a concentrating mill through a tee; the number of pipelines is reduced, and the cost is reduced.

Beneficial effects of the utility model

The utility model has the advantages that the electric cabinet is used for carrying out interlocking control on the four electric valves on the water inlet pipe, the water outlet pipe, the flushing pipe and the sewage discharge outlet, thereby realizing the automatic control of filtering and cleaning, saving labor and simultaneously ensuring the use safety; the device has the advantages of small volume, simple structure, convenient installation and maintenance, low failure rate and suitability for mineral separation water supply pipelines with small operation space and severe water supply environment; the utility model has the automatic dredging function, achieves the purpose of cleaning the interior through water flow impact, is operated by a worker through a button of the control box, and has simple and convenient filtering and cleaning operations; adopted double-deck screen cloth structure, prolonged the life of screen cloth, the sieve mesh is big-end-up's taper hole, can effectually prevent that the sieve mesh from blockking up, when long-time the use leads to the screen cloth damaged, removable screen cloth has prolonged the life of this device.

Detailed Description

The utility model discloses an electric cabinet 10, barrel 3, inlet tube 13, outlet pipe 1 and flushing pipe 12, be provided with PLC 9 in the electric cabinet 10, be provided with trash cleaning button 8 and the water supply button 11 of being connected with the PLC 9 input respectively on the electric cabinet 10, 3 lower extremes of barrel are drain 7, outlet pipe 1 passes through flange 2 and links to each other with the upper end of barrel 3 days, be provided with screen cloth 4 and lower screen cloth 5 in the barrel 3, the sieve mesh on last screen cloth 4 and the lower screen cloth 5 is big-end-up's taper hole, the aperture and the hole interval of the sieve mesh on the sieve mesh of last screen cloth 4 than screen cloth 5 down are all little, can realize secondary filter to going out water. The water outlet end of the water inlet pipe 13 is arranged in the barrel 3 below the lower screen 5, and the obliquely arranged water flow impact-proof plate 6 is arranged on the inner wall of the barrel 3 facing the water outlet end of the water inlet pipe 13, so that the direct impact of water inlet on the inner wall of the barrel 3 is avoided. The water outlet end of the flushing pipe 12 is connected with the cylinder 3 between the upper screen 4 and the water outlet pipe 1 and is communicated with the inside of the cylinder 3.
