Abstract
The utility model relates to the technical field of paper manufacturing machinery, in particular to a filtering device provided with inclined nets. The filtering device provided with the inclined nets comprises a rack, wherein overflowing grooves are formed in the upper part of the rack, water collecting grooves are arranged below the overflowing grooves, filtering nets are obliquely mounted between the overflowing grooves and the water collecting grooves, and a slurry collecting groove is formed below the water collecting groove. The filtering device is characterized in that a plurality of scraping knives are arranged on the backs of the filtering nets, blades of the scraping knives are propped against the filtering nets, and the mounting directions of the blades of the scraping knives are opposite to the flow direction of slurry. The filtering device has the benefits as follows: the water filtering effect is good, the structure is simple, the use is convenient, the operation is simple and easy, and the working efficiency is improved.
Description
Technical field
The utility model relates to the papermaking equipment technical field, relates in particular to a kind of oblique net filtration device.
Background technology
Tiltedly vertical screen frame posture absorption method is one of slurry recovery method, its principle is pulp-water to be brought up to the top of screen frame, allow pulp-water flow down from screen frame, after current network, flow to the below of oblique net from the mesh of oblique net, arrive to collect in the water device and drain again, in this drainage process, water is that other factors such as gravity on one's own account flow down, and the drainage weak effect is not thorough, cause in the paper pulp of recovery moisture many, of poor quality.
The utility model content
The purpose of this utility model is to provide a kind of oblique net filtration device, to solve traditional paper pulp water treatment plant drainage weak effect, the inefficient technical problem of drainage.
The utility model is to realize like this, a kind of oblique net filtration device, comprise frame, the top of described frame is provided with overflow launder, the below of described overflow launder is provided with water leg, between described overflow launder and water leg, is tiltedly installed with filter screen, and the below of described water leg is provided with the slurry collector groove, the back side of described filter screen is provided with some scrapers, the blade of described scraper and described filter screen offset and the installation direction of described scraper blade and slurry flow to contrary.
As further improvement, in described slurry collector groove, be provided with the spiral Size delivery unit.
After having adopted technique scheme, the beneficial effects of the utility model are:
Because the top of frame is provided with overflow launder, the below of described overflow launder is provided with water leg, be tiltedly installed with filter screen between described overflow launder and water leg, the below of described water leg is provided with the slurry collector groove, the back side of described filter screen is provided with some scrapers, the blade of described scraper and described filter screen offset and the installation direction of described scraper blade and slurry flow to contrary, like this during the water flow on filter screen, will be subject to the active force that scraper gives, increased the time of staying of moisture on filter screen simultaneously, strengthened the probability of moisture outflow filter screen, greatly improved the drainage effect, improved operating efficiency, drainage is effective, simple in structure, easy to use.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1, frame, 2, filter screen, 3, scraper, 4, overflow launder, 5, stock inlet, 6, water leg, 7, water discharge outlet, 8, the slurry collector groove, 9, grout outlet.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of oblique net filtration device, comprise frame 1, the top of frame 1 is provided with overflow launder 4, the below of overflow launder 4 is provided with water leg 6, between overflow launder 4 and water leg 6, is tiltedly installed with filter screen 2, and the below of water leg 6 is provided with slurry collector groove 8, the back side of filter screen 2 is provided with some scrapers 3, the blade of scraper 3 and filter screen 2 offset and the installation direction of scraper blade and slurry flow to contrary.
Be provided with the spiral Size delivery unit in slurry collector groove 8.
During use, give overflow launder 4 and pass into paper pulp from stock inlet 5, can from overflow launder 4, flow out after paper pulp is full, enter on the filter screen 2 of lower end connection, because filter screen 2 is more flexible, so on cloth after slurry filter screen 2 will produce distortion, in the process of distortion, moisture also can follow the deformation direction of filter screen 2 to flow, and just in time touches the scraper 3 arranged on back, and the globule will flow to because of the effect of scraper 3 below filter screen smoothly like this, enter in water leg 6, flow out from water discharge outlet 7 afterwards;
The paper pulp of dehydration is manually pulled up or is transported in the slurry collector groove 8 arranged on bottom along filter screen 2, and the inclined-plane on slurry collector groove 8 flows to bottom land fast, then in the grout outlet 9 at bottom land place, flows in the spiral Size delivery unit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
