Abstract

The utility model discloses a mechanical fiber filter controlled a cable lifter, which is suitable to the water clarification system. It is mainly composed of a cable lifter, a movable pore plate, bundle fibers filtering material and a fixing pore plate, in particular is a mechanical fiber filter, which controls the elevating of the movable pore plate to adjust fibers filtering material accumulating density by the cable lifter. The utility model is simple in structure and convenient in operation.

Description

Mechanical fiber filter

The utility model relates to a kind of improved fiber filter device (fabric filter and fibrous filtering pool), particularly a kind of bulk density and the effective positive and negative fiber filter device of washing of fiber filtering of implementing that can conveniently regulate fiber filtering.Be suitable for water supply purifying system.

At present the mechanically operated fabric filter produced of home and abroad mainly by worm drive system, sealing device, removable orifice plate, fiber filtering and fixedly orifice plate form.It utilizes the lifting of worm drive band removable orifice plate to compress and loosens fiber filtering, realizes filtering and positive and negative washing, and this transmission system complexity, sealing difficulty is big, and efficient is low, the energy consumption height.Also have a kind of lifting that utilizes cylinder to drive removable orifice plate to compress and loosen the fabric filter of fiber filtering, its structure is more complicated also, also needs to set up separately power source, and processing cost is higher.

The rapid filter that is widely used in water supply purification now all is to adopt particulate filter, and its porosity is little, and specific area is few, and flow velocity is low, so general water factory floor space is bigger.

The purpose of this utility model provides a kind of filter that utilizes the rope jack machinism to control, and it is simple in structure, and is easy to operate.

The utility model is achieved in that processing one sets of cords jack machinism, drives on the removable orifice plate by rope and moves, and utilizes the gravity of removable orifice plate to make its decline, and rope plays position-limiting action to it.By the bulk density that fiber filtering is regulated in the ascending, descending of rope control removable orifice plate, realize the filtration, purification of water, the positive and negative of fiber filtering washed.

Below with reference to accompanying drawing utility model is described in further detail.

Fig. 1 is the longitudinal profile principle schematic of an embodiment of the utility model mechanical fiber filter.

Fig. 2 is the longitudinal profile principle schematic of an embodiment of the utility model mechanical fiber filtering ponds.

With reference to Fig. 1, in a pressurized tank ［ 1 ］ lining, the fixing orifice plate ［ 4 ］ of weldering lastblock is suspended on removable orifice plate ［ 2 ］ to bundle fiber filtrate ［ 3 ］ and fixedly between the orifice plate ［ 4 ］.Be bearing in bearing ［ 5 ］ lining after fixing a reel ［ 11 ］ in the rotating shaft ［ 7 ］, prevent that with sealing device ［ 6 ］ pressurized tank ［ 1 ］ from leaking.During filtration, utilize manpower or power that rotating shaft ［ 7 ］ and reel ［ 11 ］ are rotated, rope ［ 8 ］ has discharged the lifting force to removable orifice plate ［ 2 ］ by reel ［ 11 ］ and fixed pulley ［ 10 ］, removable orifice plate ［ 2 ］ is descended, utilize the pressure differential ［ P of filter into and out of saliva ₁-P ₂And the gravity of removable orifice plate ［ 2 ］ compress fiber filtering ［ 3 ］.Like this, the impurity in the water inlet is subjected to absorption and mechanical detention effect and is held back by the surface of fiber filtering ［ 3 ］ by the small eyelet that the fiber filtering ［ 3 ］ that compresses forms, thereby reaches the filtration, purification effect of feedwater.If regulate the bulk density of fiber filtering ［ 3 ］, can drive that removable orifice plate ［ 2 ］ is upper and lower to be moved and the adjusting filter is regulated pressure differential (P into and out of saliva into and out of the flow of saliva by the rope jack machinism ₁-P ₂), the bulk density that may regulate fiber filtering ［ 3 ］ easily by two kinds of methods like this.During fiber filtering ［ 3 ］ flushing, with manpower or power rotating shaft ［ 7 ］ and reel ［ 11 ］ are rotated, rope ［ 8 ］ drives on the removable orifice plate ［ 2 ］ and moves (have mechanical link stopper ［ 9 ］ spacing) by reel ［ 11 ］ and fixed pulley ［ 10 ］, fiber filtering ［ 3 ］ bulk density is diminished, be in a kind of loose condition (of surface), be beneficial to just washing and backwash with clear water, make removable orifice plate ［ 2 ］ upper and lower mobile by the rope jack machinism, increase the frictional force between the fiber filtering ［ 3 ］, make positive and negative wash more thorough.

With reference to Fig. 2, the bottom in a conventional rapid filter ［ 15 ］ lining, distributing main ［ 14 ］ and fix a fixedly orifice plate ［ 4 ］ above the range pipe ［ 13 ］ is suspended on bundle fiber filtrate ［ 3 ］ fixedly between the orifice plate ［ 4 ］ and removable orifice plate ［ 2 ］.Reel ［ 11 ］ and fixed pulley ［ 10 ］ are fixed on the rigid support ［ 16 ］, and rope ［ 8 ］ connects reel ［ 11 ］ and removable orifice plate ［ 2 ］ by fixed pulley ［ 10 ］, and wash-water gutter ［ 12 ］ also plays the position-limiting action of removable orifice plate ［ 2 ］.The filtration of these mechanical fiber filtering ponds is identical with the mechanical fiber filter of above-mentioned Fig. 1 with the flushing principle.
