Abstract

The utility model aims at providing a rotate filter system, comprising a filter turn table, a sieve tray pressure ring, a sieve tray, a feeding template, a discharging template, a driving component, a high pressure cleaning component and a locating ring. The filter turn table is arranged between the feeding template and the discharging template; the sieve tray is arranged in the filter cave of the filter turn table and is compressed by the sieve tray pressure ring; the driving component is fixed on the upper end of the discharging template; the high pressure cleaning component is arranged on the right side of the discharging template; and the locating ring is connected between the feeding template and the discharging template. The utility model adopts the above technique proposal, can realize the helpful effect of no any pressure fluctuation and quality problem because of the large filter area.

Description

Rotating filter system

Technical field:

The utility model relates to the plastic sheeting technical field of processing equipment, refers in particular to a kind of full-automatic, technology continuous fused mass rotating filter system.

Background technology:

Filtration system commonly used at present is discontinuous type filter, the filter effect of this filter plant is relatively poor, precision is generally greater than 300 μ m, a kind of so-called continous way bicylindrical filter is arranged now as if than above-mentioned discontinuous filter advanced person, but, because this filter unites two into one melt-flow when changing filter screen, makes system pressure sharply increase.If the operating time is longer, as 15-30 minute, pressure raise and to cause that temperature raises, and can cause melt to burn, and this type of material enters and often causes in the melt-flow that film is torn, so it makes unstable product quality.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of filter area bigger, in the filter screen transfer process without any the rotating filter system of pressure oscillation and quality problems.

For achieving the above object, the technical scheme that the utility model provides is: include and filter rotating disk, filter screen dish trim ring, filter screen dish, charging template, material discharging mould, driver part, high-pressure wash parts, centring ring, filtering rotating disk is contained in the middle of the charging template material discharging mould, the filter screen dish is contained in the filtration cave of filtering rotating disk, and compress with filter screen dish trim ring, driver part is fixed on the material discharging mould top, the high-pressure wash parts are contained in the material discharging mould right side, and centring ring is connected in the middle of charging mould and the material discharging mould.

Filter screen dish of the present utility model distributes to be fixed on and filters on the rotating disk, and follows the rotation of filtering rotating disk, and by melt flow channel, when the melt-flow screen pack, foreign particle is barred from this, makes filtration system front and back pressure differential slightly increase.Control system can increase this pressure reduction makes a response, make and filter about about 1 degree of dial rotation, therefore contaminated screen pack is continuously removed melt flow channel, and clean filter screen moves into continuously, based on this working method, the filtration system operating pressure keeps constant and technology keeps continuously, before occurring in it and be about to enter melt flow channel for the cleaning of used screen pack (dirty filter screen), foul on the screen pack is washed off by the contrary purging system of a high pressure and clean again, therefore, in the filter screen transfer process without any pressure oscillation and quality problems.

Description of drawings:

Fig. 1 is this rotating filter system assembled construction schematic diagram;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment:

See shown in accompanying drawing～accompanying drawing 2,

Present embodiment includes two templates, and one is charging template 4, and another is a material discharging mould 5, filters rotating disk 1 and rotates therebetween, and be fixed together by five big centring rings 8.The Surface Machining tolerance of template is extremely little, and extremely flat harder surface is arranged, and this is the prerequisite of filter ne-leakage operation.Filter screen dish 3 is contained in the filtration cave of filtering rotating disk 1, and compresses with filter screen dish trim ring 2, and driver part 6 is fixed on the material discharging mould top, and high-pressure wash parts 7 are contained in the material discharging mould right side, and it is middle with material discharging mould 5 that centring ring 8 is connected charging mould 4.
