Description

Technical Field

[0001] The utility model relates to the field of sludge dehydration and filter pressing equipment, in particular to an electrode installation structure for sludge electric wall breaking. Background Art

[0002] For sludge carbonization treatment, drying and dehydration before the sludge enters the carbonization furnace is a key step. Currently, sludge dehydration is mostly carried out through filter presses. This treatment method can reduce the sludge moisture content to between 40% and 70%. During the plate and frame filter press process, in order to recover soluble phosphorus in the sludge, the filter press is often repeatedly switched between filtration and water washing to reduce the phosphorus content in the sludge after filtration.

[0003] Since the biomass cells and mud nuclei in the sludge contain a large amount of bound water, the filter press has limited effect on filtering out the bound water. Therefore, some existing technologies use an improved high-voltage AC pulse sludge decomposition device and its application as disclosed in application number 201711460712.1. The device sets inner and outer electrodes in the pipeline to perform electric wall breaking treatment on the sludge flowing through, thereby controlling the water content of the sludge to further decrease during the filter press process.

[0004] This type of electrostatic wall breaking treatment is carried out while the sludge is moving, and is mostly carried out during the sludge pipeline transportation. When the sludge is transported through the pipeline and electrostatic wall breaking is carried out, it is easy for the uneven water content of the sludge, lumps, air pockets and other reasons to affect the uniformity and smoothness of the sludge flow in the pipeline, thereby affecting the effect of the electrostatic wall breaking.

[0005] Based on this, the applicant proposed a sludge electrolytic wall-breaking treatment device. This device uses a canister structure with a filter cartridge installed inside. Electrode plates are installed on the filter cartridge wall. Sludge is passed into the filter cartridge, and water is injected and stirred to eliminate clumps and air pockets in the sludge. Simultaneously, the electrode plates electrolytically break the sludge walls. After the electrolytic wall-breaking is complete, excess water is filtered out through the filter cartridge and the sludge is discharged. Because the sludge needs to be stirred during operation, the electrode plates are subject to the agitation of the sludge after installation. Therefore, how to stably install the electrode plates is a key issue. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an electrode installation structure for sludge electric wall breaking, which can facilitate the installation of electrode plates and stably fix the electrode plates through a support frame, effectively solving the existing problems.

[0008] Furthermore, the support tube is provided with a hollow hole, the mounting structure includes a connecting portion that can be mounted in the hollow hole, and the support frame is detachably connected to the connecting portion.

[0009] Furthermore, the connecting portion includes a connecting block that can be installed in the hollow hole, and a limiting plate arranged on the side of the connecting block away from the support frame. The limiting plate can abut against the support tube for limiting position, and the support frame and the connecting block are detachably connected.

[0026] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In this utility model, if Figure 1-5 As shown, an electrode mounting structure for sludge electric wall breaking is provided, including a support tube 1, which is arranged to be hollow; an electrode plate 2; a support frame 3, and an inner pressure plate 301 is formed on the inner edge of the support frame 3, and the inner pressure plate 301 can be pressed on the edge of the electrode plate 2, and the support frame 3 can be detachably connected to the support tube 1 so that the inner pressure plate 301 can press and fix the electrode plate 2 on the support tube 1.

[0029] The installation structure of the present invention is shown in the figure. When installing the electrode plate 2, it is only necessary to place the electrode plate 2 in the installation position, install the support frame 3 on the outside of the electrode plate 2, and connect the support frame to the support tube 1 to achieve the fixation of the electrode plate 2. Through such installation, the electrode plate 2 does not need to be processed with the connection structure with the support tube 1, so that the finished electrode plate 2 can be purchased, and the material can be easily obtained. Moreover, the support frame 3 can press the electrode plate 2 at the outer edge of the electrode plate 2, and can fix the electrode plate 2 more evenly to prevent the edge of the electrode plate 2 from warping and deforming, especially under the impact of sludge stirring, the support frame 3 can be used to form protection for the edge of the electrode plate 2.

In this way, the hollow hole 4 of the support tube 1 can be used to connect and fix the support frame 3, eliminating the need to modify the structure of the support tube 1, thereby simplifying the structure of the support tube 1.

[0031] The surface of the support cylinder 1 can be covered with a filter cloth 5 to filter the sludge.

[0032] In a preferred embodiment, the structure of the connecting portion 6 is further specifically described as shown in the figure.

As shown in the figure, when installing the connecting portion 6, the connecting block 601 can be inserted into the hollow hole 4 from the outside of the support tube 1, so that the limiting plate 602 abuts against the outer surface of the support tube 1. After the support frame 3 is connected and fixed, the constraint of the limiting plate 602 is used to prevent the support frame 3 from separating from the support tube 1.

[0033] In a preferred embodiment, for the structure of the present invention, more specifically, the connecting block 601 is provided with a threaded hole 7. At this time, a through hole can be provided in the support frame 3, and the threaded section of the bolt 8 can be passed through the through hole of the support frame 3 and fixed in the threaded hole 7 to complete the fixation of the support frame 3.

[0038] Specifically, the connecting portion 6 can be a plastic connecting portion 6, and the connecting block 601 and the limiting plate 602 can be integrally processed by injection molding to further facilitate the connection. The deformation ability of the plastic connecting block 601 can also be used to achieve interference insertion of the connecting block 601 in the hollow hole 4.

[0039] In the illustrated embodiment, further specifically, Figure 4 As shown, the support frame 3 is provided with a waist-shaped countersunk hole 10. Figure 4 As shown, by setting the waist-shaped countersunk hole 10, the position of the connecting block 601 and the support frame 3 can be flexibly adjusted to facilitate installation.
