Description

TECHNICAL FIELD

[0001] The utility model relates to a conveying pipeline technical field especially relates to a sectional filling slurry conveying pipeline structure. BACKGROUND

[0002] Coal mine paste filling is a new filling mining mode. The paste filling slurry is mixed with ordinary cement as cementing material and fly ash as aggregate according to certain proportion, and water is stirred to prepare non-Newtonian homogeneous slurry with mass concentration of 72% to 80%, and finally the filling slurry is transported to the designated filling position through the pipeline.

[0003] During the conveying of the filling slurry, with the increase of the filling slurry concentration, the wear rate of the pipeline will increase significantly, especially on the horizontal pipeline, the pipeline wall is seriously worn due to the continuous friction with the filling slurry.

DETAILED DESCRIPTION

[0028] The specific implementation of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0029] Please refer to Figures 1-8 The utility model provides a sectional filling slurry conveying pipeline structure, including two adjacent groups of pipeline body 1 and control valve 3 and pipeline connecting assembly 4 between two adjacent groups of pipeline body 1, control valve 3 is connected through flange between the pipeline body 1 at right side, pipeline connecting assembly 4 includes main pipe 41, movable pipe 42 and fixed pipe 44, main pipe 41 is connected through flange between the pipeline body 1 at left side, movable pipe 42 is slidably arranged at the right side of main pipe 41, the outside of main pipe 41 is connected with adjusting part 43 for driving movable pipe 42 to slide relative to main pipe 41, fixed pipe 44 is connected through flange at the left side of control valve 3, the right end of movable pipe 42 and the left end of fixed pipe 44 are mutually inserted and are fixed relative to each other through fixed part 45 between the two, adjusting part 43 drives movable pipe 42 to slide relative to main pipe 41 to make movable pipe 42 and fixed pipe 44 mutually insert or separate.

[0030] The utility model discloses a pipeline connecting assembly 4 is used to connect two groups of pipeline bodies 1, when needing to replace a certain section of pipeline body 1, only needs to disconnect the pipeline connecting assembly 4 at the both ends of pipeline body 1 respectively, can realize the quick dismantling of a certain section of pipeline body 1, greatly reduces the cumbersome step in the dismantling process under the traditional flange connecting mode, and the operation is time-saving and labor-saving, and the working efficiency is improved. In addition, the connecting part of pipeline connecting assembly 4 and pipeline body 1 still uses the traditional flange connecting mode, without changing the structure of pipeline body 1.

[0031] The utility model discloses a pipeline connecting assembly 4 is used to connect two groups of pipeline bodies 1, when needing to replace a certain section of pipeline body 1, only needs to disconnect the pipeline connecting assembly 4 at the both ends of pipeline body 1 respectively, can realize the quick dismantling of a certain section of pipeline body 1, greatly reduces the cumbersome step in the dismantling process under the traditional flange connecting mode, and the operation is time-saving and labor-saving, and the working efficiency is improved. In addition, the connecting part of pipeline connecting assembly 4 and pipeline body 1 still uses the traditional flange connecting mode, without changing the structure of pipeline body 1.

[0032] Preferably, since the inner diameter of the movable pipe 42 is smaller than the inner diameter of the main pipe 41, in order to make the slurry flow more smoothly and avoid step resistance, the left end inner edge of the movable pipe 42 is chamfered. In this way, the chamfer design can effectively reduce the resistance of the slurry in the transition area.

[0033] Further, a plurality of maintenance openings 11 are provided on the upper surface of the pipeline body 1, and a connecting pipe 2 is fixedly connected to the maintenance opening 11, and a cover plate 21 is connected to the upper end of the connecting pipe 2 by bolts.

[0034] Specifically, a plurality of maintenance openings 11 are provided on the pipeline body 1, which facilitates regular inspection and maintenance of the pipeline body 1 by the staff. The staff only needs to open the cover plate 21, and then the running state and condition inside the pipeline body 1 can be directly observed through the connecting pipe 2 and the maintenance opening 11.

[0035] Further, an annular sliding groove 421 is provided at the left end of the movable pipe 42, the main pipe 41 is slidingly inserted into the annular sliding groove 421, a plurality of sealing rings 422 are arranged between the inner wall of the main pipe 41 and the outer wall of the main pipe 41 and the annular sliding groove 421 respectively, and a plurality of mounting grooves 423 for mounting the sealing rings 422 are provided on both sides of the annular sliding groove 421.

[0036] Specifically, when the adjusting member 43 adjusts the position of the movable pipe 42, the movable pipe 42 will slide relatively in the annular sliding groove 421. During the sliding process, the plurality of sealing rings 422 can effectively seal the gap between the movable pipe 42 and the main pipe 41, avoiding the problem of leakage of the slurry in the main pipe 41 and the movable pipe 42 due to sliding. Specifically, in this structure, the sealing ring 422 clamped between the outer wall of the movable pipe 42 and the annular sliding groove 421 can effectively prevent external pollutants or impurities from entering the inside of the main pipe 41 and the movable pipe 42. The sealing ring 422 clamped between the inner wall of the movable pipe 42 and the annular sliding groove 421 can prevent the slurry in the main pipe 41 and the movable pipe 42 from leaking. In addition, the sealing ring 422 is installed in the installation groove 423, which can prevent it from falling off during sliding.

[0037] Further, the left end of the main pipe 41 is fixedly connected with a flange plate 411 connected with the flange of the pipeline body 1, and the adjusting member 43 includes two groups of slide rail groups 431, which are symmetrically arranged on the front and rear sides of the main pipe 41, and the left sides of the two groups of slide rail groups 431 are fixedly connected with the flange plate 411. The side of the slide rail group 431 away from the main pipe 41 is fixedly connected with a support seat 432, and the side of the support seat 432 away from the flange plate 411 is rotatably connected with a threaded adjusting rod 433 through a bearing. The outer wall of the movable pipe 42 is symmetrically fixed with a connecting seat 434 on the front and rear sides, the connecting seat 434 is slidably connected to the inner side of the slide rail group 431, and the side of the connecting seat 434 away from the movable pipe 42 is fixedly connected with an ear seat 435 which is threadedly sleeved on the outer side of the threaded adjusting rod 433.

[0038] Specifically, when it is necessary to drive the movable pipe 42 to slide relative to the main pipe 41, precise adjustment can be achieved by synchronously rotating the two groups of threaded adjusting rods 433. During the rotation of the two groups of threaded adjusting rods 433, the two groups of ear seats 435 are synchronously moved relative to each other, and the two groups of ear seats 435 drive the movable pipe 42 to slide relative to the main pipe 41 through the two groups of connecting seats 434, thereby indirectly achieving the disconnection or connection of the pipeline connecting assembly 4, which is simple and convenient to operate.

[0039] Further, the slide rail group 431 is composed of two C-shaped slide rails 4311 which are symmetrically arranged above and below, and the upper and lower sides of the connecting seat 434 are rotatably connected with a pulley 436, and the two groups of pulleys 436 are slidably connected to the inner sides of the corresponding C-shaped slide rails 4311.

[0040] Specifically, when the movable pipe 42 slides relative to the main pipe 41, the movable pipe 42 drives the two groups of connecting seats 434 to slide in the inner sides of the two groups of slide rail groups 431, and the connecting seats 434 in turn drive the upper and lower pulleys 436 to slide in the corresponding C-shaped slide rails 4311. The relative sliding cooperation of the pulleys 436 and the C-shaped slide rails 4311 can position and guide the sliding of the movable pipe 42, ensuring that the movable pipe 42 can only slide in the direction of the C-shaped slide rails 4311. Meanwhile, the arrangement of the pulleys 436 makes the sliding of the movable pipe 42 more smooth.

[0041] Further, the right end of the movable pipe 42 is fixedly connected with an annular plug plate 424, the left end of the fixed pipe 44 is provided with an annular plug groove 441 matched with the annular plug plate 424 for plug-in connection, the right end of the fixed pipe 44 is fixedly connected with a secondary pipe 442, and the right end of the secondary pipe 442 is connected with the left side of the control valve 3 through a flange.

[0042] Specifically, the movable pipe 42 and the fixed pipe 44 are spliced by the way that the annular plug plate 424 is inserted into the annular plug groove 441, so that the two can be tightly connected and the structure is stable. When it is necessary to separate the movable pipe 42 and the fixed pipe 44, the annular plug plate 424 can be removed from the annular plug groove 441. This plug-in splicing method not only improves the efficiency of disassembly and assembly, but also greatly reduces the difficulty and time cost of maintenance. At the same time, the close cooperation of the annular plug plate 424 and the annular plug groove 441 can effectively enhance the sealing between the fixed pipe 44 and the movable pipe 42, preventing leakage during use. During use, a sealing gasket can be attached to the side of the annular plug plate 424 away from the movable pipe 42, thereby enhancing the sealing between the annular plug plate 424 and the annular plug groove 441.

[0043] Preferably, since the inner diameter of the fixed pipe 44 is smaller than the inner diameter of the secondary pipe 442, in order to make the slurry flow more smoothly and avoid step resistance, chamfering is performed on the right end inner edge of the fixed pipe 44 and the connection with the secondary pipe 442. In this way, the chamfering design can effectively reduce the resistance of the slurry in the transition area

[0044] Further, the fixing member 45 includes a plurality of stand seats 451, which are annularly arranged and fixed on the right end outer wall of the movable pipe 42. The side of the stand seat 451 away from the main pipe 41 is fixedly connected with a fixed plate 452. A plurality of fixed seats 453 are annularly arranged and fixed on the left end outer wall of the fixed pipe 44. The left side of the fixed seat 453 is provided with a fixed groove 4531 for plug-in connection of the fixed plate 452, and the fixed seat 453 and the fixed plate 452 are fixed by bolts.

[0045] Specifically, when the annular plug 424 is inserted into the annular slot 441, the fixed plate 452 is just inserted into the fixed slot 4531, at this time, the fixed plate 452 and the fixed seat 453 can be fixed by bolts, that is, the relative position between the movable pipe 42 and the fixed pipe 44 is locked, and the accidental displacement or loosening of the pipeline body 1 is prevented.

[0046] Working principle: when a certain section of the pipeline body 1 needs to be replaced, the pipeline connecting assembly 4 at both ends of the pipeline body 1 is only disconnected, so that the section of the pipeline body 1 can be quickly removed, thereby reducing the maintenance time.

[0047] Specific disassembly process of the pipeline connecting assembly 4: first, the bolt used to lock the relative position of the fixed plate 452 and the fixed seat 453 is unscrewed, at this time, the movable pipe 42 and the fixed pipe 44 lose the fixed state. Then, rotate the two sets of threaded adjusting rods 433 synchronously, the two sets of threaded adjusting rods 433 indirectly drive the movable pipe 42 to slide towards the main pipe 41, thereby driving the annular plug 424 at the right end of the movable pipe 42 to disengage from the annular slot 441 on the left side of the fixed pipe 44, at this time, the movable pipe 42 and the fixed pipe 44 are in a separated state, thereby realizing the quick disconnection of the pipeline connecting assembly 4.

[0048] Specific assembly process of the pipeline connecting assembly 4: first, place the pipeline body 1 to be replaced in place. Then, rotate the two sets of threaded adjusting rods 433 in the opposite direction synchronously, the two sets of threaded adjusting rods 433 indirectly drive the movable pipe 42 to slide away from the main pipe 41, until the annular plug 424 at the right end of the movable pipe 42 is inserted into the annular slot 441 on the left side of the fixed pipe 44. At the same time, the fixed plate 452 is also inserted into the fixed slot 4531 at the corresponding position. Finally, after being inserted into position, the fixed plate 452 and the fixed seat 453 are fixed by using bolts.

[0049] It should be noted that in actual use, the main pipe 41 and the movable pipe 42 in the pipeline connecting assembly 4 can be connected to the right end of the pipeline body 1 in advance, and the fixed pipe 44 in the pipeline connecting assembly 4 can be connected to the left end of the pipeline body 1, thereby speeding up the replacement process of the pipeline body 1.

[0050] The above is only a preferred embodiment of the present application, and is not used to limit the present application. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
