Description

The straight barrel type disk piece filter

Technical field

The utility model relates to a kind of filter, and the disk piece filter of impurity in a kind of filtered water particularly belongs to the technical field of water filtration device.

Background technology

Disk piece filter belongs to a kind of in the present various water filtration device, generally constitutes by crossing filter core and shell, base.Cross filter core and all be usually by one pile of upper and lower surface all fluted ring-shaped discs be enclosed within on the center framework, the depth of disc two sides groove and quantity have determined the whole filtering accuracy of crossing filter core, have pressure cap to compress on the disc group.During filtration: water flow through filter core from outside to inside, and impurity is trapped within disc group outer surface, and during backwash: pressure cap is by jack-up, and the disc group is unclamped, and water is from inside to outside tangentially spouting by playpipe simultaneously, and impurity is rinsed away.

What US Patent No.-6398037 and US-6419826 and Chinese patent 201020102471.0 were all described is the filter of this version, filter housing and base are by mould machine-shaping respectively, couple together with the various forms counterpart and to constitute a pressure space, disc is crossed filter core and is installed with therein, finishes the function of filtration and backwash.

Existing Chinese patent 201020047036.2 has been introduced a kind of novel disc filter element, and describe the adjustable for height design starting point of filter core and advantage in detail, its center frame design has become the branch body structure, can be according to the filtration plate accuracy that adopts, adjust the quantity of the skeleton unit that uses, namely adjust the filter area of whole filter core in the hope of reaching the maximum water flow of coupling skeleton lower opening, make the filter efficacy performance maximization of filter core, avoided waste, on-the-spot use is adjusted more flexible.

But, though this filter core design has realized adjustable height, reached purpose of design, but but there is not a kind of matching used shell design with it in the market, as continue to adopt existing shell and base form, come production and processing by mould, owing to can produce the demand of a variety of outer cover heights like this, the corresponding shell that has a lot of specifications, it is too big to make that mould drops into, and cost improves, and mould efficient is low, the shell tissue is produced also pretty troublesome, so the adjustable for height advantage of this filter core is also never given full play of.

The utility model content

The purpose of this utility model is that a kind of shell straight barrel type disk piece filter that cost is lower, simple in structure, filter efficacy is preferable and energy consumption is lower that easier production obtains is provided in order to solve the problems of the technologies described above.

To achieve these goals, the utility model is by the following technical solutions:

A kind of straight barrel type disk piece filter, it comprises: shell, upper head plate, bottom plate, mistake element kit and water inlet and delivery port, described shell upper end connects upper head plate, the lower end connects bottom plate, this is crossed element kit and is installed with in the cavity of this shell and upper head plate and bottom plate formation, it is characterized in that: described shell is the straight-tube shape structure, both ends open; Described element kit excessively is the disk type filter core, comprises disc pressure cap, skeleton loam cake, filter cartridge seat, center framework, disc group and check spare, and described center framework is for dividing body structure, and it comprises the skeleton unit of at least two series connection; The described element kit of crossing cooperates with the outer casing inner wall face also and can slide up and down along this internal face; On the described upper head plate delivery port is arranged.

The syndeton of described shell and upper head plate, described shell and bottom plate is the clamping hoop type syndeton.

On the described bottom plate water inlet is arranged.

The described element kit of crossing also includes into water termination, and described water inlet termination and skeleton loam cake are connected by connecting rod, between water inlet termination and the skeleton loam cake spring and disc pressure cap are arranged, and this spring and disc pressure cap are sleeved on the described connecting rod.

Outer shroud place, described water inlet termination is evenly equipped with the flow deflector of at least four turbo blade shapes.

Described shell is metal or fiberglass material.

Accompany the smooth light face sheet at least one two sides in the described disc group, this light face plate shape is roughly the same with the filtration disc.

The beneficial effects of the utility model: filter housing is straight barrel structure, metal or fiberglass material, but not die sinking tool mode is produced, can adopt the mode of production of the pressure vessel of counter-infiltration in the market and ultrafiltration apparatus, production standardization, versatility are good, so cost is low, the height specification is a lot, and quality is also guaranteed easily.The jointing clip of end plate is the standard universal product also up and down, and dismounting all makes things convenient for.For reaching the utility model purpose, cross also corresponding adjustment improvement of element kit: the flow deflector of water inlet termination, can avoid the current short circuit so that come water to rotate into filter from bottom to top along tangent line, and sewage also is to rotate to excrete during backwash, helps to improve to filter and the backwash effect; In addition, for the element kit of being made up of too much skeleton of crossing, because the disc group is blocked up, backwash disc group is easy to take place adhesion between disc when unclamping, influence the backwash effect, increase several light face sheets that profile is roughly the same for this reason, whole disc group initiatively can be divided into several small disc groups, improve the backwash effect, this light face tablet quality overweights the filtration disc, the material difference, adopting has self-lubricating effect material, better effects if.
