Abstract
The utility model discloses a profile sieve plate which is used to sieve the paper pulp in the paper-making industry. The hole shapes are a '< ' shape, a 'C'-shaped and a anS' shape, and the shape of the hole depth is like a horn shape. The intensity is higher than the strength of the existing sieve plate, the profile sieve plate is tear-resistant, the opening hole rate is high, and the discharging pulp rate is high.
Description
The utility model relates to a kind of Profile sieve plate, is used for the pulp screen of paper industry screening paper pulp.
In the paper industry,, adopts paper pulp pulp screen for being screened.Earlier on metallic plate, process many long narrow holes, be called sieve plate, then sieve plate is rolled into garden tubular or other shape, be loaded on the pulp screen, so that paper pulp is screened.
The hole shape of existing sieve plate is linear, sees Fig. 1.Its weak point is: the intensity of sieve plate is low, and when particularly slurry was mixed in screening, because weight impurity mixes, sieve plate was very easily torn.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and Profile sieve plate that a kind of anti tear is provided.
The purpose of this utility model can reach by following measure: the hole shape of sieve plate is "＜" shape, " C " shape and serpentine.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the local enlarged diagram of prior art (straight line hole shape sieve plate).
Fig. 2 is the utility model " local enlarged diagram of＜" shape sieve plate.
Fig. 3 is the local enlarged diagram of the utility model " C " shape sieve plate.
Fig. 4 is the local enlarged diagram of the utility model serpentine sieve plate.
The utility model is described in further detail below in conjunction with embodiment: the hole shape of sieve plate is "＜" shape (see figure 2), " C " shape (see figure 3) and serpentine (see figure 4).The shape of sieve plate hole depth is like tubaeform, sees shown in Fig. 2,3 and 4 the sectional drawing.Width between the straight length of the width of sieve plate hole seam, hole seam and hole seam and the hole seam is all identical with prior art (straight line hole shape sieve plate).
The utility model contrast prior art has following advantage: the intensity of sieve plate increases, energy anti tear, thereby the service life of having improved sieve plate; Under the constant situation of hole shape straight length, prolonged the length of hole seam, thereby improved the percent opening of sieve plate; Horn shape on the seam degree of depth of hole helps leading slurry, has reduced logical slurry resistance, thereby has improved pulping rate.
Claims (2)
1, the sieve plate used of a kind of pulp screen is characterized in that, the hole shape of sieve plate be "
" shape, " C " shape and serpentine.
2, sieve plate according to claim 1 is characterized in that, the shape of sieve plate hole depth is like tubaeform.
