Description

Technical Field

[0001] This utility model relates to the field of sludge treatment, and in particular to an electro-disrupting pipe flow guiding structure. Background Technology

[0002] For sludge carbonization treatment, drying and dewatering before the sludge enters the carbonization furnace is a crucial step. Currently, sludge dewatering is mostly carried out using filter presses, which can reduce the sludge moisture content to between 40% and 70%.

[0003] Since the biomass cells and sludge cores in sludge contain a large amount of bound water, the effect of pressure filtration on the removal of bound water is limited. Therefore, some existing technologies use an improved high-pressure AC pulse sludge decomposition device and its application disclosed in application number 201711460712.1. This device uses internal and external electrodes in the pipeline to electro-break the sludge flowing through it, thereby controlling the sludge moisture content to decrease further during the pressure filtration process.

[0004] Existing sludge electro-disruption equipment has the following problems when in use: it is difficult to balance the sludge flow rate and the electro-disruption effect. That is, when the sludge moves too fast in the pipe, the electro-disruption effect is limited. Although reducing the sludge flow rate in the pipe improves the electro-disruption effect, it has a significant impact on the sludge feeding rate.

[0005] Based on this, the applicant improved the pipeline-type sludge cell disruption structure. Specifically, the pipeline is divided into a conveying pipeline and an electro-disrupting pipeline connected to the conveying pipeline. The electro-disrupting pipelines are connected to each other by flanges. The inner diameter of the electro-disrupting pipeline is larger than that of the conveying pipeline, so that the flow cross-section of the electro-disrupting pipeline is larger than that of the conveying pipeline. The sludge flow velocity in the electro-disrupting pipeline decreases, thereby increasing the thoroughness of sludge electro-disruption in the electro-disrupting pipeline. At the same time, the small-diameter conveying pipeline reduces the overall radial dimension of the pipeline and maintains the sludge flow velocity in the conveying pipeline, thereby improving the treatment effect of sludge electro-disruption.

[0006] At the connection between the conveying pipeline and the electro-disrupting pipeline, the sludge flow cross-section changes instantaneously, causing turbulence in the sludge at this location. This increases the resistance to sludge flow and creates turbulent impacts on the flange end face of the conveying pipeline and the inner surface of the electro-disrupting pipeline, even causing erosion and affecting the overall stability of the pipeline.

[0007] Therefore, how to guide the smooth flow of sludge in the conveying pipeline and the electro-disruption pipeline is an urgent problem to be solved. Utility Model Content

[0008] To address the aforementioned technical problems, this utility model provides an electro-disruptive pipe flow guiding structure, which can guide sludge to flow at the junction of the conveying pipe and the electro-disruptive pipe through a flow guiding cylinder, and the flow guiding cylinder is easy to install, effectively solving the problems existing in the prior art.

[0009] To address the aforementioned problems, this utility model provides an electro-disruptive pipe flow guiding structure, comprising a conveying pipe and an electro-disruptive pipe. The inner diameter of the electro-disruptive pipe is larger than the inner diameter of the conveying pipe. The conveying pipe is provided with a first flange, and the electro-disruptive pipe is provided with a second flange connected to the first flange. The flow guiding structure further includes a flow guiding cylinder, one end of which is connected to the first flange or the inner side of the electro-disruptive pipe, and the other end of which abuts against the first flange or the electro-disruptive pipe at a corresponding position via a sealing ring. The inner surface of the flow guiding cylinder gradually increases in size along the direction from the conveying pipe toward the electro-disruptive pipe.

[0010] Furthermore, one end of the guide tube is connected to the first flange, and the other end abuts against the inside of the electric wall-breaking pipe through a sealing ring.

[0011] Furthermore, the guide tube is connected to the first flange via threaded fasteners.

[0012] Furthermore, the threaded fastener includes a stud welded to the first flange and a nut capable of being screwed onto and fixed to the stud;

[0013] The guide tube is provided with an outer flange, and the outer flange is provided with a through hole for the stud to pass through.

[0014] Furthermore, a sealing gasket is clamped and fixed between the outer flange and the first flange.

[0015] Furthermore, the flow guiding structure includes a supporting rib disposed on the outside of the flow guiding cylinder. One end of the supporting rib is connected to the outer flange, and the other end is connected to the flow guiding cylinder. The axis of the supporting rib is parallel to the axis of the electric wall-breaking pipe.

[0016] Furthermore, the flow guiding structure also includes an outer cylinder rib disposed on the outside of the flow guiding cylinder, and a support ring rib connected to the outer cylinder rib and the flow guiding cylinder and / or the support cylinder rib; one end of the outer cylinder rib is connected to the end of the flow guiding cylinder away from the outer flange, and the other end is connected to the support ring rib, and the sealing ring is provided between the outer surface of the outer cylinder rib and the conveying pipe.

[0017] Furthermore, the supporting ring reinforcement is connected to the side of the supporting cylinder reinforcement;

[0018] Alternatively, the supporting ring rib is connected to the guide tube, and the supporting tube rib is connected to the side of the supporting ring rib.

[0019] Furthermore, the outer diameter of the outer cylinder rib gradually decreases along the direction toward the electric wall-breaking pipe.

[0020] Furthermore, a plurality of sealing gaskets are provided coaxially between the outer flange and the first flange.

[0021] The beneficial effect of this utility model is that it can guide the sludge to flow at the junction of the conveying pipeline and the electric wall-breaking pipeline through the guide tube, and the installation of the guide tube is easy, which effectively solves the problems existing in the prior art.

[0028] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0029] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0032] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] In this utility model, such as Figure 1-3 As shown, an electro-disruptive pipe flow guiding structure is provided, including a conveying pipe 1 and an electro-disruptive pipe 2. The inner diameter of the electro-disruptive pipe 2 is larger than the inner diameter of the conveying pipe 1. The conveying pipe 1 is provided with a first flange 101, and the electro-disruptive pipe 2 is provided with a second flange 201 connected to the first flange 101. The flow guiding structure also includes a flow guiding cylinder 3. One end of the flow guiding cylinder 3 is connected to the first flange 101 or the inner side of the electro-disruptive pipe 2, and the other end abuts against the first flange 101 or the electro-disruptive pipe 2 at the corresponding position through a sealing ring 4. The inner surface of the flow guiding cylinder 3 gradually increases in the direction from the conveying pipe 1 toward the electro-disruptive pipe 2.

[0034] During installation, the flow guiding structure of this utility model can be pre-fixed at a position in either the conveying pipe 1 or the electro-disrupting pipe 2. When connecting the conveying pipe 1 and the electro-disrupting pipe 2, the flow guiding cylinder 3 is inserted entirely into the electro-disrupting pipe 2, thus completing the installation of the flow guiding cylinder 3 inside the electro-disrupting pipe 2. When the sludge flows between the conveying pipe 1 and the electro-disrupting pipe 2, as shown in the figure, the inner surface of the flow guiding cylinder 3 is set into a conical surface to guide the sludge flow and prevent turbulent sludge flow from directly impacting the first flange 101 and the inner surface of the electro-disrupting pipe 2.

[0035] In the illustrated embodiment, specifically regarding the structure of this utility model, as shown in the figure, one end of the guide tube 3 is connected to the first flange 101, and the other end abuts against the inner side of the electric wall-breaking pipe 2 via a sealing ring 4. This allows the guide tube 3 to be fixed to the first flange 101 from the outside of the first flange 101, facilitating operation.

[0036] In alternative embodiments, the end of the guide tube 3 may be pre-connected to the inner surface of the electro-breaking pipe 2 (e.g., by welding or by bolting).

[0037] In the illustrated embodiment, more specifically regarding the structure of this utility model, as shown in the figure, the guide tube 3 is connected to the first flange 101 by threaded fasteners.

[0038] Alternatively, the guide tube 3 can also be welded to the first flange 101.

[0039] For threaded fastener connection methods, in Figure 1 In the embodiment shown, more specifically, as shown in the figure, the threaded fastener includes a stud 5 welded to the first flange 101 and a nut 6 that can be screwed and fixed to the stud 5; the guide tube 3 is provided with an outer flange 7, and the outer flange 7 is provided with a through hole for the stud 5 to pass through.

[0040] As shown in the figure, this allows for easy tightening and loosening of the nut 6 from the outside of the guide tube 3 when assembling the guide tube 3 into the first flange 101.

[0041] In the illustrated embodiment, a further optimization is that, as shown in the figure, a sealing gasket 8 is clamped and fixed between the outer flange and the first flange 101.

[0042] As shown in the figure, this can prevent sludge from entering the outside of the guide tube 3, and further prevent the threaded fasteners, the first flange 101 and the second flange 201 from rusting.

[0043] In the illustrated embodiment, a further optimization is provided, as shown in the figure, that the flow guiding structure includes a support rib 9 disposed on the outside of the flow guiding cylinder 3. One end of the support rib 9 is connected to the outer flange 7, and the other end is connected to the flow guiding cylinder 3. The axis of the support rib 9 is parallel to the axis of the electro-disrupting pipe 2. As shown in the figure, by providing the support rib 9, the flow guiding cylinder 3 can be positioned by the support insertion auxiliary support, thereby preventing deformation of the flow guiding cylinder 3.

[0044] In a preferred embodiment, a further optimization of the present invention is that the flow guiding structure further includes an outer cylinder rib 10 disposed on the outside of the flow guiding cylinder 3, and a support ring rib 11 connecting the outer cylinder rib 10 to the flow guiding cylinder 3 and / or the support cylinder rib 9;

[0045] One end of the outer cylinder rib 10 is connected to the end of the guide cylinder 3 away from the outer flange 7, and the other end is connected to the support ring rib 11. The sealing ring 4 is provided between the outer surface of the outer cylinder rib 10 and the conveying pipe 1.

[0046] As shown in the figure, this increases the installation area of ​​the sealing ring 4 by increasing the number of sealing rings 4 or the sealing area, which helps to improve the sealing effect. The supporting ring ribs 11 and the outer cylinder ribs 10 improve the structural strength of the guide tube 3, further preventing deformation of the guide tube 3.

[0047] In the illustrated embodiment, more specifically, as shown in the figure, the supporting ring rib 11 is connected to the side of the supporting cylinder rib 9.

[0048] Alternatively, as shown in the figure, the supporting ring rib 11 is connected to the guide tube 3, and the supporting tube rib 9 is connected to the side of the supporting ring rib 11.

[0049] In the illustrated embodiment, a further optimization of this invention is that, as shown in the figure, the outer diameter of the outer cylinder rib 10 gradually decreases along the direction towards the electro-blending pipe 2. This reduces the resistance when the guide cylinder 3 enters the electro-blending pipe 2.

[0050] In the illustrated embodiment, more specifically, a plurality of sealing gaskets 8 are provided coaxially between the outer flange 7 and the first flange 101.

[0051] It should be noted that the improvement of this utility model lies in the flow guiding structure at the positions of the electric wall-breaking pipe 2 and the conveying pipe 1. There are no restrictions or improvements on the electrode installation of the electric wall-breaking pipe 2 or the inner electrode on the inner side of the electric wall-breaking pipe 2. As one example, an installation hole is opened in the electric wall-breaking pipe 2, and the electrode plate 12 is installed in the installation hole to form the outer electrode installation of the electric wall-breaking pipe 2. An electrode cylinder 13 is provided on the inner side of the electric wall-breaking pipe 2. Electrode arc plates are provided on both the inner and outer surfaces of the electrode cylinder 13. An electrode rod 14 is provided on the inner side of the electrode cylinder 13.
