Description

Pulp drainage inclined net device

Technical Field

The utility model relates to the technical field of papermaking equipment, in particular to a pulp drainage inclined screen device.

Background

The pulping workshop is provided with a plurality of bed inclined net concentrating device equipment which are mainly distributed in the heavy slag remover, the trench recycling pulp and other working sections. The method has the main effects of concentrating the slurry concentration of the system and recovering the fibers in the waste water produced in the workshop trench so as to meet the production process requirements, stabilizing production, filtering the fibers in the recovered waste water, filtering and dehydrating the large impurities in the waste water, and reducing the system fiber loss and the waste water treatment difficulty of the water treatment workshop.

The existing inclined screen device can lay a layer of nylon screen on the steel plate screen according to different concentration requirements during operation, the concentrated and filtered slurry flows onto the nylon screen surface from the top of the inclined screen, and flows downwards to filter out part of white water through the gravity principle, so that the purpose of concentrating and filtering is achieved.

However, after the nylon filter screen is paved, the nylon filter screen is extremely easy to wear due to the fact that the nylon filter screen contacts with the opposite convex points or edges of the net surface of the steel plate net under the scouring of high-flow slurry for a long time, so that a large number of holes or tearing openings appear, a large number of fibers enter the white water system, and the burden of the system production or sewage treatment system is affected.

Disclosure of Invention

The utility model aims to provide a pulp drainage inclined screen device for solving the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the pulp water filtering inclined net device comprises a water filtering groove, wherein the front end of the water filtering groove is close to a pulp receiving groove, a supporting plate is arranged at the rear end of the water filtering groove, an inclined steel plate net is paved from the top of the supporting plate to the edge of the water filtering groove, connecting rods which are transversely arranged are fixed at the upper end and the lower end of the steel plate net, and a lining net is arranged between the two connecting rods;

the top of backup pad still is equipped with a plurality of first string knot, the front end border department of drainage groove is equipped with a plurality of second string knot, it has a nylon filter screen to hang to connect between first string knot and the second string knot, the nylon filter screen is located the lining net top.

Preferably, the two sides of the lining net are provided with sleeves, and the sleeves at the two sides are respectively sleeved on the corresponding connecting rods.

Preferably, the mesh number of the nylon filter screen is 60-115 mesh.

Preferably, the mesh number of the lining mesh is 6 mesh.

Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, a lining net is paved between the nylon filter screen and the steel plate net, so that the direct contact surface of the surface layer filter screen and the steel grid is blocked, the dewatering effect of the filter screen is not affected, and the phenomenon of replacement caused by frequent abrasion of the surface layer filter screen is avoided; the mesh number of the specially-arranged lining net is 6 meshes, so that the silk threads of the lining net are relatively thick, have certain stiffness, the net surface is relatively smooth, firm and wear-resistant, and the meshes are relatively large, so that the dewatering function of the surface layer filter screen is not affected.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the present utility model provides a technical solution: the utility model provides a paper pulp drainage inclined wire device, includes drainage groove 1, the front end of drainage groove 1 is next to stock tank 2 the rear end fixed mounting backup pad 3 of drainage groove 1, then lay a steel sheet net to be the slope form and fix between the top of backup pad 3 to the border of drainage groove 1, simultaneously at the connecting rod 41 that the upper and lower both ends of this steel sheet net 4 all fixed a horizontal setting, can overlap between two connecting rods 41 and install lining net 5.

In this embodiment, a plurality of first hanging buckles 31 are further disposed on the top of the supporting plate 3, a plurality of second hanging buckles 11 are disposed at the edge of the front end of the water filtering tank 1, and then a nylon filter screen 6 is hung between the first hanging buckles 31 and the second hanging buckles 11, and the nylon filter screen 6 is located above the lining screen 5.

In this embodiment, the sleeves 51 are disposed on two sides of the lining net 5, and then the sleeves 51 on two sides are respectively sleeved on the corresponding connecting rods 41, so that the lining net is mounted above the steel plate net, and the lining net can be disassembled and replaced by disassembling the sleeves on the connecting rods.

In this embodiment, the nylon filter screen 6 has a mesh number of 60-115 mesh for concentrating the filtered slurry.

In this embodiment, the mesh number of the lining mesh 5 is 6, so the silk threads of the lining mesh are relatively thick, have a certain stiffness, the mesh surface is relatively flat, firm and wear-resistant, and the mesh openings are relatively large, so that the dewatering function of the surface layer filter screen is not affected.

In summary, a lining net is laid between the nylon filter screen and the steel plate net to prevent the direct contact surface of the surface layer filter screen and the steel mesh, and the dewatering effect of the filter screen is not affected, so that the phenomenon of replacement caused by frequent abrasion of the surface layer filter screen is avoided; the mesh number of the special lining net is 6 meshes, so that the silk threads of the lining net are relatively thick, have certain stiffness, the net surface is relatively flat, firm and wear-resistant, the meshes are relatively large, and the dehydration function of the surface layer filter screen is not affected
