Description

Technical Field

[0001] The utility model relates to the field of sludge treatment, in particular to a pipeline type sludge electric wall breaking structure. Background Art

[0002] For sludge carbonization treatment, drying and dehydration before the sludge enters the carbonization furnace is a key step. At present, sludge dehydration is mostly carried out by filter press, which can reduce the moisture content of sludge to between 40% and 70%.

[0003] The biomass cells and mud cores in the sludge contain a large amount of bound water, and 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 No. 201711460712.1, which arranges inner and outer electrodes in the pipeline to perform electrical 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] In the existing pipeline external electrode setting method, the sludge flow pipe is set to an insulating material, and then the external electrode is set outside the sludge flow pipe. The sludge flow pipe is made of a transparent quartz tube, and the sludge flow pipe is connected to the metal pipe through a metal flange head.

[0005] In actual use, the durability and processability of the transparent quartz tube are insufficient, especially after the diameter of the quartz tube increases to 50 mm, the strength of the quartz tube is difficult to maintain and it is easy to be damaged under vibration. Based on this, the applicant optimized and improved the external electrode structure of the pipeline sludge. Utility Model Content

[0025] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0028] In the present utility model, 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 utility model. 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.

[0029] In the present utility model, if Figure 1-4 As shown, a pipeline sludge electric wall breaking structure is provided, including a pipeline 1, wherein the pipeline 1 is a metal pipeline 1, a mounting hole 2 is opened on the surface side of the pipeline 1, an inner electrode 3 is arranged in the pipeline 1, and an outer electrode plate 4 is installed at the position of the mounting hole 2 of the pipeline 1.

[0030] The electric wall breaking structure of the utility model adopts a mounting hole 2 opened on a metal pipe 1 to install an outer electrode plate 4. The metal pipe 1 is easy to obtain, and the processing and manufacturing cost is low. The metal pipe 1 is not easy to be damaged during use, and the structure is stable. Especially when the diameter of the pipe 1 increases to more than 50 cm, compared with the existing quartz insulation pipe 1, the metal pipe 1 of the present application has a stable and durable structure. In some working conditions, in order to reduce the viscous resistance of the inner wall of the pipe 1 to the flow of sludge and inhibit the sludge from clumping on the inner wall of the pipe 1, in some embodiments, a vibrating member can also be provided on the outer electrode plate 4 to promote the flow of sludge at the outer electrode plate. The metal pipe 1 is relatively stable and not easy to be damaged under vibrating working conditions.

[0031] In addition, by opening the installation hole 2 in the pipeline 1, the present application can use the finished outer electrode plate 4 to directly act on the sludge in the pipeline 1. Compared with the method of using an insulating pipeline 1, the electric field action distance between the outer electrode plate 4 and the sludge is shortened.

[0032] In a preferred embodiment, the arrangement of the utility model is further specifically described as shown in the figure, the pipeline 1 is provided with a plurality of mounting holes 2 at intervals along its length direction, and the pipeline 1 is provided with a plurality of mounting holes 2 at intervals along its circumferential direction in each of the mounting holes 2. As shown in the figure, the outer electrode plates 4 are arranged at intervals along its circumferential direction on the outside of the pipeline 1, and the pipeline 1 portion between the mounting holes 2 is used to maintain the structural strength of the pipeline 1.

[0033] In the illustrated embodiment, for the installation mechanism of the utility model, further specifically, as shown in the figure, the outer edge of the outer electrode plate 4 is provided with an installation side edge 401, and the installation side edge 401 overlaps the outer surface of the pipe 1 at the edge of the installation hole 2, and the inner surface of the outer electrode plate 4 is consistent with the contour of the inner surface of the pipe 1. As shown in the figure, after the outer electrode plate 4 is installed, the inner surface of the outer electrode plate 4 is roughly consistent with the inner surface contour of the pipe 1, so as to reduce the viscosity of the sludge when it flows inside and reduce the sludge agglomeration.

[0034] In the illustrated embodiment, the pipe 1 is provided with a supporting step at the edge of the mounting hole 2, and the mounting side edge 401 overlaps the supporting step. The supporting step is arranged in the structural style of the mounting plate, and the outer electrode plate 4 is fixed to the mounting plate so that the mounting side edge 401 extends out of the edge of the outer electrode plate 4.

[0035] In the illustrated embodiment, a further optimized setting of the utility model is that, as shown in the figure, an elastic spacer ring 5 is provided between the inner edge of the mounting hole 2 and the outer electrode plate 4. The elastic spacer ring 5 can achieve sealing between the outer electrode plate 4 and the pipeline 1 to prevent sludge from leaking out, and can also reduce the vibration transmitted between the outer electrode plate 4 and the pipeline 1 during the sludge flow process to improve the stability of the connection between the pipeline 1 and the outer electrode plate 4. In particular, in some working conditions, when a vibrating member is provided on the outside of the outer electrode plate 4, the vibration transmitted from the outer electrode plate 4 to the pipeline 1 can be reduced; or in some working conditions, when the outer electrode plate vibrates due to the impact of sludge flow, the vibration transmitted from the outer electrode plate 4 to the pipeline 1 can be reduced.

[0036] As a preferred embodiment, the structure of the elastic spacer ring 5 in the utility model is further specifically described as shown in the figure, the elastic spacer ring 5 includes a support layer 501 and elastic layers 502 arranged on both sides of the support layer 501. As shown in the figure, by providing the support layer 501, the shape of the elastic spacer ring can be kept stable to prevent the elastic spacer ring from being dislocated during installation and use, especially when the outer electrode plate vibrates, the elastic spacer ring 5 can be prevented from moving and dislocating to maintain the sealing and vibration isolation of the elastic spacer ring 5.

[0037] In a preferred embodiment, for the structure of the utility model, more specifically, the support layer 501 is set as a ceramic support layer 501. By setting the ceramic support layer 501, the heat insulation of the ceramic support layer 501 can be used to reduce the heat transfer to the elastic layer outside the ceramic support layer 501 when the outer electrode plate 4 is heated, and the elastic force of the elastic layer 502 outside the ceramic support layer 501 is maintained to suppress the weakening of the sealing due to the softening of the elastic layer 502 due to heat.

[0038] In the illustrated embodiment, for the installation of the outer electrode plate 4, to be more specific, as shown in the figure, the electric wall breaking structure also includes a fixing frame 6, the fixing frame 6 is connected to the outer surface of the pipe 1, and the fixing frame 6 can press the installation side 401 on the pipe 1. As shown in the figure, the outer electrode plate 4 is pressed and fixed by the dedicated fixing frame 6, so that the outer electrode plate 4 can provide a relatively balanced extrusion force to the elastic separation ring 5 between the pipe 1 to maintain the stable installation of the outer electrode plate 4. In addition, there is no need to drill holes or weld the outer electrode plate 4.

[0039] In the illustrated embodiment, with regard to the installation structure of the fixing frame 6 , to be more specific, as shown in the figure, the fixing frame 6 is fixed to the pipeline 1 by threaded fasteners.

[0040] In the illustrated embodiment, more specifically, a threaded connection column 12 is provided at the edge of the installation hole 2 of the pipeline 1, and a nut 7 is fixed on the connection column to press and fix the fixing frame 6.

[0041] Through such an arrangement, when a single outer electrode plate 4 fails or is damaged, the single outer electrode plate 4 can be easily disassembled. The utility model can also use the mounting hole 2 to clean and maintain the inside of the pipeline 1.

[0042] In the illustrated embodiment, for the structure of the utility model, further specifically, as shown in the figure, the inner electrode 3 includes a plurality of support ribs 8 arranged at intervals around the pipe 1 in the circumferential direction, and the support ribs 8 are connected to the pipe 1 in the area at the edge of the mounting hole 2.

[0043] As shown in the figure, the inner electrode 3 can be installed through the support rib 8, so that the inner electrode 3 can be stably installed. As for the connection method between the support rib 8 and the pipeline 1, specifically, as shown in the figure, the support rib 8 is provided with a threaded hole, and the connecting bolt 9 is fixed to the support rib 8 after passing through the wall of the pipeline 1. The connecting bolt 9 is provided with a positioning ring on the outer part of the pipeline 1, and an elastic sealing gasket is provided between the positioning ring and the pipeline 1. In this way, when the inner electrode 3 needs to be taken out, the connecting bolt 9 can be removed. Compared with the existing insulating quartz pipeline 1, the utility model adopts a metal pipeline 1, and a fixing structure of the support rib 8 can be provided in the pipeline 1, which makes it easier to achieve stable installation and fixation of the inner electrode 3.

[0044] In the illustrated embodiment, the arrangement of the inner electrode 3 is used as an exemplary description. The inner electrode 3 includes an electrode tube 11 and an electrode rod 10 arranged inside the electrode tube 11. The outer surface of the electrode tube 11 is provided with an outer electrode arc plate, and the inner surface of the electrode tube 11 is provided with an inner electrode 3 tube arc plate, so that an electric wall breaking action area is formed between the outer electrode arc plate and the outer electrode plate 4, and an electric wall breaking action area is formed between the inner electrode 3 arc plate and the electrode rod 10. After increasing the inner diameter of the pipeline 1, the electrode tube 11 is used to form two inner and outer electric wall breaking action areas to improve the treatment effect of the electric wall breaking of the sludge. Based on the large weight and certain length of the electrode tube 11, the electrode tube 11 is connected and fixed in the pipeline 1 by the support ribs 8, which can effectively maintain the stability of the structure and position of the electrode tube 11.

[0045] The arrangement of the inner electrode 3 is not limited to the manner including the electrode tube 11 as shown in the figure. In an optional embodiment, an electrode rod 10 may also be arranged in the pipeline 1, and an electric wall breaking area is directly formed between the electrode rod 10 and the outer electrode plate 4.

[0046] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
