The flexible filter interlayer is provided with water seepage holes, and a drainage channel is formed inside the flexible filter interlayer. The support is arranged in the drainage channel along the length direction of the drainage channel, and the support is used to support the flexible filter interlayer and allow the water in the filter bag to seep out through the flexible filter interlayer.
[0006] Optionally, the filter bag and the flexible filter interlayer are integrally formed.

[0024] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0025] As shown in Figures 1 to 3 The present application provides a kind of mud rapid dehydration filter device, including filter bag 1, flexible filter sandwich 4 and support 2.Mud injection port 11 is equipped on filter bag 1.Mud injection port 11 is located at the top of filter bag 1.Flexible filter sandwich 4 is located in filter bag 1, and is sealed with filter bag 1 Connection, to form mud storage cavity between filter bag 1 And flexible filter sandwich 4.Water seepage hole is equipped on flexible filter sandwich 4, and drainage channel 41 is formed in flexible filter sandwich 4.Support 2 is located in drainage channel 41 Along the length direction of drainage channel 41, support 2 is used to support flexible filter sandwich 4 And allow moisture in filter bag 1 Pass through flexible filter sandwich 4 Seepage.
[0026] In the mud rapid dehydration filter device of the present application, high-pressure mud 3 is injected into the mud storage cavity through the mud injection port 11, and the moisture in the mud 3 is discharged through the outer surface of the filter bag 1 and the water seepage hole of the flexible filter sandwich 4 under the action of the pressure of the mud 3 and the gravity of the moisture itself. Because the moisture in the mud 3 can be discharged through the water seepage hole of the flexible filter sandwich 4, the drainage area of the filter bag 1 is increased, the efficiency of moisture discharge is improved, and the processing efficiency of the dehydration and drying of the mud 3 is further improved.
[0027] As shown in Figures 1 to 3 Filter bag 1 and flexible filter sandwich 4 are integrally formed, so that filter bag 1 and flexible filter sandwich 4 are well sealed, and the production efficiency is high.
[0028] In some embodiments, the material of the flexible filter sandwich 4 is the same as that of the filter bag 1. The filter bag 1 and the flexible filter sandwich 4 are both woven mesh bags. The woven mesh bag is usually made of plastic materials such as polypropylene (PP), polyethylene (PE), etc., and can also be made of natural fibers such as jute, etc. The woven mesh bag has a mesh structure, good air permeability, allows moisture to pass through, and prevents the mud 3 from passing through. The woven mesh bag has high strength and wear resistance, and can withstand a certain weight. The woven mesh bag also has corrosion resistance and can resist the corrosion of chemicals, and is suitable for various environments.
[0029] In some embodiments, the filter bag 1 and the flexible filter interlayer 4 are both geotextile bags. Geotextile bags are a kind of geosynthetic material products used in civil engineering, usually made of high-strength, wear-resistant geotextile materials, which can be filled with materials such as sand, gravel, concrete, slurry 3, etc., and used for various engineering structures and environmental management projects. Geotextile bags are usually made of high-strength synthetic materials such as polypropylene (PP) and polyester (PET). Geotextile bags are durable, have good resistance to ultraviolet light, chemical corrosion and biological degradation, are also water permeable, which is beneficial to the drainage of water, and have a certain flexibility, which can adapt to different terrain and structural requirements.
[0030] As shown in Figure 1 and Figure 2 , the drainage channel 41 is one, and the drainage channel 41 is arranged at the middle of the filter bag 1, so that the distance of water in the slurry 3 in the slurry storage cavity to the drainage channel 41 is substantially the same, so that the dehydration rate of the slurry 3 is relatively uniform, and the dehydration effect is good.
[0031] As shown in Figure 3 , in some embodiments, the number of drainage channels 41 is multiple. The multiple drainage channels 41 are uniformly distributed on the filter bag 1. Each drainage channel 41 is respectively provided with a support 2. As shown in Figure 3 , the number of drainage channels 41 is 4, of course, the number of drainage channels 41 can be set according to the size of the filter bag 1, and the number of drainage channels 41 is not limited herein. In this embodiment, since multiple drainage channels 41 are provided, not only the drainage area of the filter bag 1 is increased, but also the migration distance of water is shortened, so that the drainage efficiency is further improved.
[0032] As shown in Figure 1 , the drainage channel 41 penetrates through the filter bag 1 to form two drainage openings, so that the water discharged into the drainage channel 41 can be discharged through the two drainage openings respectively, improving the efficiency of water discharge.
[0033] In some embodiments, the support 2 is detachably arranged in the drainage channel 41. In this example, the support 2 is detachably arranged, which is convenient for later disassembly, maintenance or replacement.
[0034] As shown in Figures 1 to 3 , the support 2 is a spiral steel wire. The spiral steel wire can not only meet the requirement of supporting the wall surface of the drainage channel 41, but also not hinder the drainage of the wall surface of the drainage channel 41. As shown in Figure 1 , the slurry 3 extrudes the flexible filter interlayer 4 under the action of pressure and its own gravity, so that the water in the slurry 3 can be discharged through the water permeable holes on the flexible filter interlayer 4. For example, the diameter of the spiral steel wire is 2 to 4 mm. Of course, the diameter of the spiral steel wire can also be set according to actual needs.
[0035] In some other embodiments, the support 2 is a cylinder with the cylinder wall being provided with drainage holes. The cylinder can meet the requirement of supporting the wall surface of the drainage channel 41 and does not hinder the drainage of the wall surface of the drainage channel 41. Of course, the support 2 can also be other structures as long as it can play a supporting role and does not hinder the drainage of the wall surface of the drainage channel 41.
[0036] In some embodiments, the cross section of the drainage channel 41 is circular, prismatic or rectangular. Preferably, the cross section of the drainage channel 41 is circular. The circular drainage channel 41 makes the force uniform and the drainage effect better.
[0037] In some embodiments, one or more supports 2 can be arranged in the drainage channel 41 according to the requirement. When one support 2 is arranged, the cross section size of the support 2 is consistent with the cross section size of the drainage channel 41. When multiple supports 2 are arranged, the sum of the cross section sizes of the multiple supports 2 is consistent with the cross section size of the drainage channel 41.
[0038] According to the above description of the present specification, those skilled in the art can also understand that the terms used such as "upper", "lower", "horizontal", "top", "bottom", "inner", "outer" and the like indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present specification, which are only for the purpose of facilitating the description of the scheme of the present utility model and simplifying the description, and are not explicitly or implicitly indicating or suggesting that the devices or elements involved must have the specific orientation, be constructed and operated in the specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as the limitation of the scheme of the present utility model.
[0039] In addition, in the description of the present specification, the meaning of "multiple" is at least two, such as two, three or more, etc., unless otherwise explicitly and specifically limited.
