Description

The backpulsing water filter

Technical field:

The utility model relates to a kind of water filter of coal-winning machine, particularly a kind of water filter that has scavenge unit.

Background technology:

In the atomizing de-dusting system of coal-winning machine, supply water by water pump, its water source is the mine water of mine normally, obviously mostly damage ratio is more serious at these water sources, the mine water water quality that pump sucks is relatively poor, contain all kinds of particulate contaminants in the water, as directly mine water being infeeded the atomizing de-dusting system, the associated components of its pollutant in may the grievous injury system, for this reason, early stage water supply control techniques such as the sedimentation basin that adopts purifies when practical, mine water purifying station etc., problem makes it be difficult to promote the use of but its clean-up effect is poor, and infrastructure investment is big etc., the pipeline water filter is generally adopted in the atomizing de-dusting systematic comparison of existing coal-winning machine, and gradually form the dustproof pipeline fluid contaminant filter equipment special of cooling, and corresponding series specification is arranged, its actual measurement filter efficiency can reach more than 80%, but the common issue with of existing these water filters is, need regularly dismounting to clean filter core, use inconvenience, also increase running cost; At this, dealer's exploitation has the novel automatic self-cleaning filter, as PM60 series of Britain Mi Ke company etc., can regularly clean as required, its cleaning frequency can be controlled according to pollution concentration in the water that detects automatically automatically, cleaning adopts the high speed rotary water current, dash to remove and accumulate in filter screen outside pollutant, and can not interrupt the supply of filtered water, but the structure of this water filter is complicated greatly, its cost of manufacture is far above the existing product that uses, and the specification requirement of operation and maintenance also significantly promoted, further increase its use cost, under existing coal-mining technique condition, be difficult to promote the use of.

The utility model content:

Technical problem to be solved in the utility model is: a kind of improved backpulsing water filter is provided, and it can realize flushing filter core outside pollutant in the process of filtered water without interruption, and simple in structure, easy to operate, making and use cost are all lower.

The technical scheme in the invention for solving the above technical problem is:

In the housing of backpulsing water filter filter core is set, this housing one end is provided with delivery port, its other end is connected with contiguous block, be provided with ball valve in this contiguous block, this contiguous block other end is provided with water inlet, ball valve is controlled opening or closing of this water filter, be characterized in: described backpulsing water filter has an operating mechanism, this operating mechanism is connected with the big ball valve that is arranged in the contiguous block, also has the small ball that is connected with big ball valve in this contiguous block, this small ball one side is connected with the recoil delivery port, has outer flow passage in this contiguous block, this outer flow passage is connected with small ball and housing exocoel respectively, has inner flow passage in this contiguous block, this inner flow passage is connected with housing inner chamber and small ball respectively, also has side runner in this contiguous block, this side runner is connected with housing exocoel and big ball valve respectively, when operating mechanism is in recoil 1 the time, water inlet is communicated with through filter core and delivery port, the part water of water inlet is through inner chamber, through hole, exocoel, the realization recoil is discharged at the reflexive mouth of a river of going out of outer flow passage and small ball, when operating mechanism is in recoil 2 the time, water inlet is through side runner, exocoel, through hole and inner chamber, through filter core from inner flow passage, small ball and the discharging of recoil delivery port realize recoil, and part water flows out from delivery port.

Large and small ball valve of the present utility model, and be aided with inside and outside, side runner, realize that the interrupt delivery filtered water does not reach the purpose of washing filter core outside pollutant, its structure and existing filter difference are little, but can simplify the maintenance clean operation of filter greatly, can significantly reduce the cost of manufacture and the use cost of water filter, and can favourablely on various coal-winning machines, promote the use of, have good economic benefit and social benefit.
