Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter cloths, and in particular to high-precision filter cloths. Background Art
[0002] During the production process, edible oil requires filtration to remove suspended solids and oil residue. Currently, edible oil filtration is mostly performed using a plate and frame filter press. The filter components of a plate and frame filter press primarily consist of a filter frame, filter plates, and filter cloth. The filter cloth intercepts solid particles, achieving a solid-liquid separation effect.
[0003] However, in actual use, people have found that as time goes by and the number of uses increases, the filter cloth is prone to changes in physical properties due to friction with solid particles, causing the fibers of the filter cloth to loosen or tear, resulting in a larger filter aperture, making it difficult to maintain good filtration accuracy for a long time, thereby affecting the service life of the filter cloth. Utility Model Content
[0004] The utility model provides a high-precision filter cloth, which solves the problem in the related art that the filter cloth's filter aperture becomes larger due to friction with solid particles, affecting its service life.
[0005] The technical solution of the utility model is as follows:
[0006] The high-precision filter cloth includes a first cloth body and a second cloth body. The first cloth body and the second cloth body are integrally formed. The first cloth body and the second cloth body each include a plurality of filter layers. Each of the filter layers has a plurality of filter holes. Each of the filter layers is arranged in sequence along a linear direction, and the filter holes of adjacent filter layers are staggered.
[0007] Furthermore, each of the filter layers has a steep twill structure.
[0008] Furthermore, a connection frame for connecting the filter layers is provided between each filter layer of the first cloth body and the second cloth body.
[0009] Furthermore, a fixing structure for fixing the first cloth body and the second cloth body on the filter plate is provided between the connection frames.
[0010] Furthermore, the fixing structure includes a plurality of limiting components, each of the limiting components includes a limiting rope for connecting the first cloth body and the second cloth body, and a plurality of limiting holes for the limiting rope to pass through, and each of the connecting frames has a plurality of limiting components.
[0011] Furthermore, the limiting holes on the first cloth body correspond to the limiting holes on the second cloth body one by one, and adjacent limiting holes are staggered.
[0012] Furthermore, each of the limiting holes is provided with a stabilizing tube body, and the stabilizing tube body is fixedly connected to the connecting frame.
[0013] Furthermore, each of the filter layers is made of fine-denier polyester DTY low-elastic yarn material.
[0014] The working principle and beneficial effects of the utility model are as follows:
[0015] 1. The first and second fabric bodies of the present invention both have a plurality of filter layers, each having a plurality of filter holes. The filter layers are arranged in sequence along a linear direction, so that when the present invention realizes solid-liquid separation, only one filter layer comes into contact with the solid particles in the oil. When the filter layer is damaged, the solid particles will come into contact with the next filter layer. That is, each filter layer plays the role of filtering the oil in sequence, effectively ensuring the filtration accuracy and service life of the present invention.
[0016] 2. The filter holes on adjacent filter layers in the present invention are staggered, thereby avoiding the overlap of the filter holes on adjacent filter layers (filter media), so that the spacing between adjacent filter holes on each filter layer is different or arranged in an irregular form. Compared with the orthogonally arranged filter holes, the staggered filter holes enable the fluid to be more evenly distributed on each filter layer when passing through, thereby reducing the probability of local flow rate being too fast or too slow, which is conducive to uniformly dispersing the oil flow and the pressure generated when filtering the oil, avoiding different pressures in different parts of each filter layer, resulting in damage to the filter layer, and ensuring the service life of the filter layer.
[0017] 3. At the same time, since the axes of the filter holes in the present invention are not on the same straight line, it can effectively prevent the fine solid particles in the oil from moving smoothly along the filter holes on each filter layer, and prevent the fine solid particles from simultaneously wearing the filter holes on each filter layer, causing the filter hole diameter to become larger, thereby fully ensuring the filtering accuracy of this embodiment.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1
[0028] like Figures 1 to 3 As shown, this embodiment proposes a high-precision filter cloth, which mainly includes a first cloth body 1 and a second cloth body 2. The first cloth body 1 and the second cloth body 2 are integrally formed to ensure the strength and stability of the overall structure of this embodiment.
[0029] Both the first fabric body 1 and the second fabric body 2 include a plurality of filter layers 3, each having a plurality of filter holes 31. The filter layers 3 are arranged in sequence along a linear direction. That is, during the filtration process of this embodiment, the filtered material (oil) passes through each filter layer 3 in sequence, so that during the filtration process, only one filter layer 3 comes into contact with the solid particles in the oil, and the filter layer 3 isolates the solid particles, so that the solid particles only come into contact with the filter layer 3 that isolates them, effectively reducing the wear of the embodiment caused by the solid particles in the oil.
[0030] At the same time, the filter holes 31 of adjacent filter layers 3 are staggered, thereby preventing the filter holes 31 on adjacent filter layers 3 (filter media) from overlapping each other in the vertical horizontal plane, so that the spacing between adjacent filter holes 31 on each filter layer 3 is different. Compared with the orthogonal arrangement of the filter holes 31, the staggered arrangement of the filter holes 31 allows the fluid to be more evenly distributed on each filter layer 3 when passing through the filter layer 3, thereby reducing the probability of local flow rate being too fast or too slow, which is conducive to uniformly dispersing the oil flow and the pressure generated when filtering the oil, avoiding different pressures in different parts of each filter layer 3, resulting in damage to the filter layer 3, and ensuring the service life of the filter layer 3; and the axes of the filter holes 31 are not on the same straight line, which can effectively prevent fine solid particles in the oil from moving smoothly along the filter holes 31 on each filter layer 3, and prevent fine solid particles from simultaneously wearing out the filter holes 31 on each filter layer 3, resulting in the pore size of the filter holes 31 becoming larger, fully ensuring the filtration accuracy of this embodiment.
[0031] Each filter layer 3 has a steep twill structure. Even if the warp and weft yarns constituting the filter layer 3 are interlaced to form oblique lines, the floating lines of each filter layer 3 can be longer. Under the conditions of the same thickness and density of the warp and weft yarns, its anti-friction and wear resistance are better than those of plain fabrics, so that each filter layer 3 in this embodiment can better resist wear and tear; and due to the staggered arrangement of the warp and weft yarns, the interlacing points between the yarns are effectively increased, thereby fully improving the overall strength of the filter layer 3.
[0032] Furthermore, each filter layer 3 is made of fine-denier polyester DTY low-stretch yarn. Specifically, the yarn used to weave the filter layers 3 is preferably fine-denier polyester DTY low-stretch yarn. This ensures that this embodiment also possesses the advantages of fine-denier polyester DTY low-stretch yarn: high breaking strength and elastic modulus, excellent heat setting and resilience, good corrosion and heat resistance, and easy cleaning, fully ensuring the practicality of this embodiment.
[0033] A connecting frame 4 for connecting each filter layer 3 is provided between each of the first and second fabric bodies 1 and 2. This connecting frame 4 smoothes the irregular side surfaces of the filter layers 3 (first and second fabric bodies 1 and 2), maintaining a smooth surface for installation in a plate-and-frame filter press, such as a filter plate. Specifically, the first and second fabric bodies 1 and 2 in this embodiment each include a connecting frame 4 and a plurality of filter layers 3. The connecting frame 4 is similarly woven from fine-denier polyester (DTY) yarn, allowing it to connect to each filter layer 3. The connecting frame 4 and each filter layer 3 are preferably woven together and, if necessary, can be secured by heat pressing to ensure the overall strength of this embodiment.
[0034] A fixing structure 5 is provided between each connecting frame 4 for fixing the first cloth body 1 and the second cloth body 2 on the filter plate, which facilitates the staff to install this embodiment on the filter plate, thereby cooperating with the filter plate, filter frame and other plate and frame filter press filter components to complete the filtration work.
[0035] The fixing structure 5 includes a plurality of limiting components 51, each of which includes a limiting rope 511 for connecting the first cloth body 1 and the second cloth body 2, and a plurality of limiting holes 512 for the limiting rope 511 to pass through. Each limiting rope 511 is detachably connected to the first cloth body 1 and the second cloth body 2. Compared with the existing limiting rope 511 (fixing rope) directly fixed on the first cloth body 1 and the second cloth body 2, the detachable limiting rope 511 greatly avoids the limit rope 511 from breaking when the centrifugal cleaning machine is used to clean the filter cloth, resulting in the first cloth body 1 and the second cloth body 2 being unable to be installed. The phenomenon of being installed on the filter plate occurs, which affects the service life of the filter cloth; and through the mutual cooperation between the limiting ropes 511 and the limiting holes 512 opened on the connecting frame 4, the first cloth body 1 and the second cloth body 2 can be better restrained. With the help of this restraining effect, this embodiment is fixed on the filter plate, and after the fixation is completed, the ends of the limiting ropes 511 are knotted to prevent the limiting ropes 511 from detaching from the first cloth body 1 and the second cloth body 2; each connecting frame 4 has a plurality of limiting components 51, so as to perform multiple constraints on this embodiment and ensure the stability of this embodiment after installation.
[0036] like Figure 4 As shown, since the connecting frame 4 itself is relatively soft, in order to avoid deformation of the limiting holes 512 opened in the connecting frame 4, which makes it difficult to pass the limiting rope 511, a stabilizing tube body 6 is provided in each limiting hole 512 in this embodiment. The stabilizing tube body 6 is fixedly connected to the connecting frame 4, and the structural structure of the stabilizing tube body 6 itself plays a role in supporting the limiting hole 512 to facilitate the passing of the limiting rope 511.
[0037] Example 2
[0038] Different from Example 1, Figure 5 As shown, this embodiment proposes that: each limiting hole 512 on the first cloth body 1 corresponds to each limiting hole 512 on the second cloth body 2 one by one, so that the constraint work is completed by passing through each limiting hole 512 at the same time, so that the staff does not need to carry too many limiting ropes 511 when installing this embodiment, which facilitates the installation work of this embodiment; adjacent limiting holes 512 are staggered, so that the staff can identify the order of the limiting holes 512 through which the limiting rope 511 is to be passed, thereby improving the installation speed of this embodiment.
[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
