Description

Technical Field

[0001] The present invention relates to the technical field of pipeline filtration, in particular to a filtration structure and a slag flushing jellyfish pipe. Background Art

[0002] In recent years, the 165MW boilers at the thermal power plant have adopted a hydraulic ash conveying system. The slag produced by the boilers is collected in a slag pool using slag flushing water. This is then pumped to a dehydration bin via an ash pump for dehydration. The separated slag water is then pumped to the slag flushing water main in the second plant for recycling. Due to the age of the equipment, the slag-water separation in the dehydration bin is less than ideal, resulting in ash in the slag flushing water. This causes frequent clogging of the ditch nozzles in the second plant, leading to nozzle failure and ditch blockage. To address this issue, the present invention provides a filtration structure and slag flushing water main pipeline. Summary of the Invention

[0003] In view of the problems existing in the above-mentioned existing filtering structure and slag flushing jellyfish pipe pipeline, the present invention is proposed.

[0004] Therefore, one of the objects of the present invention is to provide a filtering structure, the purpose of which is to improve the filtering effect of slag.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a filtering structure comprising:

[0013] As a preferred solution of the filtration structure of the present invention, a sewage discharge portion is provided at the bottom of the filtration pipe, and the sewage discharge portion is used to seal the filtration pipe.

[0014] As a preferred solution of the filtering structure of the present invention, the filtering portion includes a mounting cylinder and a plurality of filtering holes arranged in the mounting cylinder.

[0015] As a preferred solution of the filtering structure of the present invention, a plurality of blades are provided on the inner side of the installation cylinder, and the blades drive the installation cylinder to rotate when in contact with the circulating liquid.

[0016] As a preferred solution of the filtering structure of the present invention, wherein: an annular base is provided at the bottom of the mounting cylinder, and an interception groove is provided on the base;

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0036] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0037] Example 1, with reference to Figure 1-Figure 4 , which is a first embodiment of the present invention, provides a filtering structure, which includes a liquid passing pipe 1 and a filtering pipe 2;

[0038] A liquid passage M is provided inside the liquid passage pipe 1 for liquid to flow through, and flanges are installed at both ends of the liquid passage pipe 1 to facilitate its installation in the transport pipeline.

[0039] The filter pipe 2 is connected to the liquid passage pipe 1, and a filter portion 21 is provided inside the filter pipe 2. The inlet end N of the filter portion 21 passes through the liquid passage M. When the liquid flows inside the liquid passage M, it will pass through the inlet end N. After the liquid passes through the inlet end N, it enters the filter portion 21, and finally is discharged from the filter portion 21 and enters the liquid passage M again. When the liquid flows in the liquid passage M, impurities will be filtered out by the filter portion 21.

[0040] Furthermore, the filter portion 21 is rotatably disposed in the filter pipe 2 . When the liquid passes through the filter portion 21 , the rotating filter portion 21 can increase the effective filtration area of the filter portion 21 , thereby increasing the service life of the filter portion 21 .

[0041] The filter portion 21 includes a mounting tube 211 and a plurality of filter holes 212 disposed in the mounting tube 211. The top of the mounting tube 211 is an inlet end N, and the top of the mounting tube passes through a liquid passage M. When the liquid passes through the liquid passage M, it enters the mounting tube 211 and the filter holes 212, and then returns to the liquid passage M to complete the filtration of the liquid.

[0042] Among them, a drain part 22 is provided at the bottom of the filter pipe 2, and the drain part 22 is used to close the filter pipe 2. The drain part 22 closes the bottom of the filter pipe 2 so that the liquid will not be discharged from the bottom of the liquid pipe 1 after entering the installation cylinder 211, ensuring that the liquid will return to the filter channel again after passing through the installation cylinder 211.

[0043] Furthermore, a raised block 11 is provided on the inner wall of the liquid passage 1, and the bottom of the raised block 11 is in contact with the filter portion 21; the inlet end N runs through the entire liquid passage M, and the raised block 11 reduces the cross-sectional area of the liquid passage M. The top of the mounting cylinder 211 of the filter portion 21 can be lowered so that the top of the inlet end N is against the raised block 11, and the inlet end N is lower than the bottom of the liquid passage M, so that the inlet end N runs through the entire filter channel, ensuring that the liquid enters directly from the inlet end N.

[0044] Furthermore, the inner wall on the same side of the protrusion 11 and the inlet end N is a guide side 111. The guide side 111 is arc-shaped and the bottom intersects with the inlet end N. The liquid will turn when passing through the guide side 111, causing the flow direction of the liquid to change, thereby causing the liquid to vertically enter the inlet end N at the front end of the mounting cylinder 211.

[0045] Furthermore, a plurality of blades 213 are provided on the inner side of the mounting cylinder 211. When the blades 213 come into contact with the circulating liquid, the mounting cylinder 211 will be driven to rotate. The liquid will change its path when passing through the guide side 111, so that the liquid enters the inlet end N as directly as possible. When the liquid comes into contact with the blades 213, the blades 213 will be driven to rotate, thereby driving the mounting cylinder 211 to rotate. The rotating mounting cylinder 211 can make all the annular filter holes 212 perform filtering operations, thereby improving the utilization rate of the filter holes 212.

[0046] The bottom of the mounting tube 211 is provided with an annular base 214, and a blocking groove 215 is provided on the base 214. When the mounting tube 211 is inserted into the filter channel, it contacts the blocking groove 215, thereby limiting the position of the mounting tube 211.

[0047] A protruding ring 23 is provided at the bottom of the filter pipe 2, and a limiting block 24 is provided on the protruding ring 23. The limiting block 24 is plugged into and matched with the blocking groove 215. During the filtering operation, the sewage discharge part 22 lifts up the protruding ring 23, so that the limiting block 24 is separated from the blocking groove 215, and the top of the installation cylinder 211 contacts the blocking groove 215.

[0048] When draining sewage, the sewage discharge part 22 needs to be removed. At this time, the mounting cylinder 211 will drive the base 214 to contact the convex ring 23 under the impact of the water flow, and the limit block 24 will be inserted into the blocking groove 215, thereby blocking the rotation of the mounting cylinder 211, eliminating the influence of the centrifugal force of the mounting cylinder 211 on the impurities in the filter hole 212, so that when the water flow impacts the impurities adsorbed inside the mounting cylinder 211, it will drive the impurities out of the mounting cylinder 211 and finally be discharged from the bottom of the filter pipe 2. There are multiple blocking grooves 215 and limit blocks 24, and they are evenly spaced. The top of the base 214 is an inclined surface to prevent impurities from accumulating and remaining on the base 214.

[0049] A threaded groove is provided on the inner side of the convex ring 23, and the sewage discharge part 22 includes a threaded column 221 and a nut 222. The threaded column 221 is threadedly connected to the convex ring 23, and the top of the threaded column 221 is in contact with the base 214. The contact surface between the two is smooth. After the threaded column 221 is threadedly connected to the convex ring 23, the threaded column 221 will lift the mounting cylinder 211, so that the base 214 is separated from the convex ring 23, and the nut 222 is in contact with the bottom of the convex ring 23, thereby closing the filter pipe 2.

[0050] During use, the liquid will pass through the interior of the mounting tube 211 when entering the liquid passage M, and will be discharged from the filter hole 212 and enter the liquid passage M again. When the liquid passes through the filter hole 212, impurities will be removed, thereby removing impurities inside the liquid.

[0051] Example 2, reference Figure 5-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the sewage discharge part 22 includes a mounting block 223 arranged at the bottom of the convex ring 23, wherein a right-angle groove 224 is provided in the mounting block 223, one end of the right-angle groove 224 is communicated with the filter pipe 2, and a closed ring 225 is provided in the direct groove, wherein the closed ring 225 is arranged parallel to the base 214, and a mounting shaft 226 is threadedly connected to the mounting block 223, and an extrusion plate 227 is provided at the end of the mounting shaft 226, and a sealing plate 228 is provided in the middle of the mounting cylinder 211, wherein the extrusion ring is abutted against the base 214, and the sealing plate 228 is in contact and sealed with the closed ring 225, thereby separating the right-angle groove 224, wherein the other end of the right-angle groove 224 can be used to install a sewage pipe.

[0052] When the installation shaft 226 controls the extrusion ring to abut against the base 214, and the sealing plate 228 contacts and seals the closing ring 225, the installation cylinder 211 abuts against the blocking groove 215, and the base 214 separates from the convex ring 23. At this time, the bottom of the filter pipe 2 is closed, and the liquid passes through the installation cylinder 211 to be filtered.

[0053] When the installation shaft 226 controls the extrusion ring to separate from the base 214, and the sealing plate 228 separates from the closing ring 225, the bottom of the filter pipe 2 is opened, and the base 214 is contacted and limited by the convex ring 23 and cannot rotate. At this time, the impurities inside the installation cylinder 211 are discharged from the filter pipe 2 along with the water flow.

[0054] The remaining structures are the same as those of Example 1.

[0055] Example 3, reference Figure 7 , which is a third embodiment of the present invention, provides a slag flushing jellyfish pipe pipeline, including a slag flushing pipe 3 and a slag pool 4;

[0056] The slag pool 4 is connected to the slag flushing pipeline 3, and a filtering structure is provided in the slag flushing pipeline 3.

[0057] The remaining structures are the same as those of Example 2.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
