Abstract
The utility model relates to a screening apparatus using a screen plate strainer to screen the slurry, belonging to the apparatus of the paper making industry. The utility model adopts an arc-shaped screen plate of 700-900 mm, and the upper part of the screen plate is fixedly connected with the labial plate of a slurry jetting mouth on the upper part of a box body. The slurry jetting mouth is provided with an opening deegree regulator. A slurry inlet pipe is arranged on the upper part of the box body by that the flange plane of the slurry inlet pipe and the horizontal plane form 45DEG, ane besides, the ingression direction of the slurry liquid is coincident to the tangential direction of the radian of the screen plate. As a consequence, the utility model has the advantages of simple structure, no rotary and vibrating elements, difficult damage, long service life, no power transmission, high efficiency, low consumption, etc.
Description
The utility model relates to a kind of equipment that carries out the slurry screening with the sieve plate filter screen, be applicable to that the paper pulp of paper industry concentrates, in the processing procedures such as deinking washing, also be useful in the starch in the food industry, in the production processes such as sugaring.
Domestic more common screening plant is the frame sieve that shakes at present, and it is mounted with sieve plate in casing, is used as power with motor, produces vibration by eccentric disc, makes that the liquid material that promptly need screen filters by the slurry of sieve plate.This shortcoming of shaking the frame sieve is to expend electric power, be used as power with motor, energy consumption is bigger, and slurry stops up sieve aperture (seam) easily, generally sparge pipe is arranged constantly to wash away at the sieve plate upper unit, with anti-clogging, this has obviously increased energy consumption again, has increased the complexity of structure, the frame sieve is carrying out constantly vibration when work owing to shake, therefore the consumable accessory of equipment is more, damages easily, and service life is short.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, to provide a kind of efficient, energy-conservation, and does not rotate or vibrating mass, does not need power transmission, the screening installation that screening effeciency is higher.
The purpose of this utility model is finished by following technical solution, and promptly sieve plate is an arc shape, and its top is fixed on the labial lamina of mouth spray, and mouth spray is provided with the aperture adjuster.
With its Flange Plane and the horizontal plane casing top that is placed at 45, and its slurries approach axis is consistent with sieve plate radian tangential direction with pulp-inlet pipe for the utility model.
The utility model is selected the arc screening plate of arc radius 700～900mm for use, and the sieve seam is the slit shape, and section is wedge shape, and the sieve seam is wide to be 0.05～0.2mm.
Aperture adjuster described in the utility model is made up of screw mandrel, nut and handwheel etc.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 is the utility model mouth spray and controller structure schematic diagram.
To be described in detail the utility model by accompanying drawing below: Fig. 1-Fig. 2, casing 1 has corrosion resistant plate weldering system to form, the bottom is funnel-form, and top is mounted with the pulp-inlet pipe 3 of band adpting flange 2, and the arrangement of this pulp-inlet pipe 3 becomes α=45 with the plane of its flange 2 with horizontal plane ° be the best.Mouth spray 4 on the pulp-inlet pipe 3 is provided with aperture adjuster 5, and it is by screw mandrel 6, and nut 7 and handwheel 8 are formed, and nut 7 is connected on the fixed mount 9 on the casing 1, and screw mandrel 6 can rotate in nut 7, and its leading section is tight against on the adjustable wall of mouth spray 4, sees accompanying drawing 3.The special slit shape that is processed into of sieve plate 10 usefulness stainless steels, section is wedge shape, so that dehydration, sieve seam width is 0.05～0.20mm, specifically can select according to the size of concentration of fluid and solid content by user's technological requirement.Above-mentioned sieve plate 10 is an arcuation, and arc radius is chosen in 700～900mm, and the top of sieve plate 10 is fixed on pressing plate 11 on the labial lamina 12 of mouth spray 4, and the both sides of sieve plate 10 are with regulating bolt by the angle bar clamping, so that dismounting.
The utility model is to utilize pumping fluid tangentially to spray into the arc compass screen surface, relies on centrifugal force and Gravity Separation solid content and liquid, simultaneously, clean filter wash net (sieve plate) by means of the rolling of the solid content of separating and the souring of liquid waterpower, play self purification, be characterized in simple structure, do not rotate and vibrating mass, not fragile, long service life does not need power transmission, less energy consumption, characteristics such as dehydration thickening efficiency height are that domestic a new generation is efficient, the screening installation of low consumption.
