Description

Herringbone net belt

Technical Field

The utility model relates to a solid-liquid separation equipment technical field especially relates to a chevron shape guipure.

Background

The belt filter press is a solid-liquid separation device, which is widely applied to the filtration of various industries such as biochemical sludge, mine sludge, electroplating sludge, paper mill pulp and the like. The dehydration principle is as follows: the solid-phase-containing material enters an upper mesh belt and a lower mesh belt which are in a tensioned state and continuously rotate in a belt filter press, and then the solid-phase-containing material passes through a series of rolling cylinders to be extruded so as to achieve the aim of dewatering.

For a belt filter press, a filter mesh belt is the core of the filter mesh belt, the existing mesh belt which is usually woven by 3 heald weaving is low in flatness, so that materials are easy to remain on the surface of the mesh belt, and meanwhile, the mesh belt is easy to elongate and extend in the pressurizing process, so that the materials are easy to enter the mesh belt.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

In the description of the present invention, it is to be noted that the terms "upper", "bottom", "inner", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and should not be construed as limiting the present invention.

Referring to fig. 1-2, the herringbone mesh belt comprises a plurality of warps 1 and a plurality of wefts 2, wherein the warps 1 are woven in a top-three-bottom-four manner, the arrangement of the warps 2 is 5-30 warps 2 per cycle, in a single cycle, the interval of the warps 2 passing through the wefts 1 is one for any adjacent warps 2, and the warps 2 are in a continuous ascending or descending trend.

In particular, as shown in figure 1, the so-called warp 2 and weft 1, which are terms common in the field of weaving, respectively denote the longitudinal and transverse threads of the textile fabric. Meanwhile, the upper three-lower four-weaving mode means that the warp 2 firstly passes through 3 weft 1 and is arranged above the weft 1, then passes through 4 weft 1 and is arranged below the weft 1, and then passes through 3 weft 1 and is arranged above the weft 1, and the process is repeated. In fig. 1, the solid line portions of the warp threads 2 indicate portions thereof provided above the weft threads 1, and the dotted line portions of the warp threads 2 indicate portions thereof provided below the weft threads 1.

The arrangement of the warp threads 2 is 5 to 30 warp threads 2 per cycle, which means that, because the warp threads 2 in each cycle have a characteristic arrangement manner in the embodiment, the number of the warp threads 2 in each cycle is 5 to 30.

For any adjacent warp yarn 2, the interval of passing through the weft yarn 1 is one, and the warp yarn has a trend of continuously ascending or continuously descending. That is, when the warp 2 has a continuous ascending trend, for the nth warp 2, the nth warp firstly passes through the ith weft 1 and is arranged above the (i to i + 2) th weft 1, and then passes through the (i + 3) th weft 1 and is arranged below the (i +3 to i + 6) th weft 1; then, for the n +1 th warp 2, the warp firstly passes through the (i + 1) th weft 1 and is arranged above the (i + 1) th to (i + 3) th wefts 1, and then passes through the (i + 4) th weft 1 and is arranged below the (i + 4) th to (i + 7) th wefts 1; for the n-1 th warp yarn 2, the warp yarn firstly passes through the (i-1) th weft yarn 1 and is arranged above the (i-1) th to i +1 th weft yarns 1, and then passes through the (i + 2) th weft yarn 1 and is arranged below the (i + 2) th to i + 5) th weft yarn 1. When the warp threads 2 are in a continuously descending trend, the arrangement direction is opposite.

And the warp threads 2 may have different or the same tendency to change in adjacent cycles, for example, in some cases, the warp threads 2 all tend to rise for m, m-1, m-2, etc. cycles, but the warp threads 2 tend to fall for m +1, m +2, m +3, etc. cycles.

Meanwhile, since the weaving manner of top three and bottom four is adopted in this embodiment, the arrangement of the warp 2 is preferably a multiple of 7 per cycle, such as 7 warps 2, 14 warps 2, 21 warps 2, and so on.

The mesh belt real object diagram prepared when each cycle of the arrangement of the warp threads is 7 warp threads is shown in fig. 2, and as can be seen from fig. 2, in the cycle on the left side, the warp threads tend to rise; in the right cycle, the warp is descending. Meanwhile, as can be seen from the figure, the herringbone mesh belt has good compactness and high flatness.

The method for using the mesh belt of this embodiment is the same as that of the conventional mesh belt, and therefore, the process of using the mesh belt is not described in detail.

Meanwhile, the inventor found that when the arrangement of the warp threads 2 is a multiple of 7 per cycle, it has a better effect, and particularly when the arrangement of the warp threads 2 is 7 per cycle, it is applied to a belt filter press, and compared with a conventional 3-heddle woven mesh belt, it has the following effects:

can effectively save the medicament volume, 3 of conventionality are heald and are woven the guipure, and its net space ratio is great, and the material leaks easily, and the guipure of this embodiment, its structure of weaving is very inseparable, consequently, the material is difficult for leaking. Through the experiments of the inventor, the dosage of the medicament (such as flocculating agent and the like) can be reduced by 20-30% under the condition of long-time work.

The material breaks away from soon, because the braided structure of guipure of this embodiment is inseparable, and its roughness is higher relatively simultaneously, consequently, the guipure surface is smooth, and the material is peeled off easily.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiments of the present invention are all covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
