Description

Technical Field

[0001] The invention relates to the technical field of concentrator cleaning, in particular to a rake-type concentrator guide tube cleaning device. Background Art

[0002] The rake thickener mainly uses the principle of gravity sedimentation to separate solid particles from liquid. Its basic structure includes a thickening tank, a rake, a drive device and a discharge pipe. After the slurry enters the rake thickener, it is separated into agglomerates and filtrate by the screen plate. Under the action of the rake and the screen plate, the coal sludge agglomerates are compressed and sent to the discharge port, thereby achieving the purpose of concentration. In order for the coal sludge concentrate to be fed into the tank at a stable flow rate, the cleanliness of the feed pipe must be maintained to prevent the concentrate from condensing and affecting the passing efficiency.

[0003] However, the existing cleaning agencies have the following deficiencies:

[0004] Since the cleaning position is at the connection between the pool bottom and the guide tube, the operating space for on-site cleaning is small, and the guide tube structure is conical in shape, and its inner diameter varies. Therefore, when the traditional cleaning structure is pushed into the inner side of the conical guide tube from bottom to top, due to the continuous change of the inner diameter of the guide tube, the traditional cleaning structure cannot keep the brush head always in contact with the inner wall of the pipe, so that the attached coal slurry cannot be fully removed by the force of the brush head during removal, and the treatment effect is not ideal. In addition, when the fitting distance between the brush head and the inner wall of the pipe changes due to the movement along the closing structure in the tube, the spray width of the spray mechanism for spraying the dissolved medium cannot be adjusted adaptively. When the diameter of the guide tube is reduced and the sprayed dissolved medium is too concentrated, its dissolved coverage area cannot meet the expected requirements as the diameter of the guide tube is reduced. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a cleaning device for a guide tube of a rake-type concentrator.

[0008] Preferably, an assembly linkage plate is fixedly connected between the embedded transmission rod and the transmission rod member, the transmission rod member and the embedded transmission rod are arranged parallel to the embedded transmission rod, the embedded transmission rod and the transmission rod member slide synchronously through the assembly linkage plate, and the sliding extension length of one end of the transmission rod member fixedly connected to the directional transmission wheel is greater than the sliding extension length of the embedded transmission rod.

[0009] Preferably, a flow control groove is provided at one end of the single-way storage tube close to the wall-adhering flow guide cleaning brush head, the foldable sealing plug is slidably connected to the inner side of the flow control groove, the foldable sealing plug is fixedly connected to a sealing strip on one side close to the embedded transmission rod, and the single-way storage tube and the inner wall of the flow control groove are sprayed with Teflon coating.

[0010] Preferably, a pressure trigger switch is fixedly connected to the inner side of the flow control guide groove, and the pressure trigger switch is connected to the electric drive nozzle signal.

[0011] Preferably, the dissolving medium transport assembly includes a storage barrel, an injector and a connecting valve head, the storage barrel is mounted on the upper end of the connecting valve head, the injector is slidably connected to the storage barrel, the storage barrel and the injector are used to inject the dissolving medium into the single-way storage tube fitting, and a folding bellows is also provided at one end of the intermediate tilt bracket, the output end of the folding bellows is threadedly connected to the single-way storage tube fitting, and the other end of the folding bellows is fixedly connected to a two-way connecting valve, and the input end of the two-way connecting valve is detachably connected to the storage barrel.

[0012] Preferably, an anti-slip groove is opened on the inner side of the retractable transmission seat, one end of the transmission rod slides and extends to the inner side of the anti-slip groove, and a wall-holding spring is fixedly connected between the end of the transmission rod located on the inner side of the anti-slip groove and the anti-slip groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a central connection component, an inner diameter contraction component and an intermediate tilting bracket as a pushing mechanism for cleaning into the cylinder, when the intermediate tilting bracket enters the single-pass storage pipe, the contact distance between the wall-adhering diversion cleaning brush head and the transmission rod and the wall surface can be changed synchronously according to the inner diameter size of the cylinder, so that the wall-adhering diversion cleaning brush head is always in contact with the cylinder wall during movement to complete scraping and cleaning, avoiding movement restrictions while fully bringing out the attached coal slurry.

[0017] 2. When the middle tilt bracket moves on the wide-diameter cleaning surface in the cylinder, the electrically driven nozzle is used as the spraying end of the dissolving medium. When the middle tilt bracket moves to the narrow-diameter cleaning surface in the cylinder, the middle tilt bracket is compressed to produce relative movement. The directional transmission wheel is squeezed by the cylinder wall to drive the transmission rod to shrink inwardly of the contraction transmission seat, so that the assembly linkage piece synchronously drives the embedded transmission rod to move inwardly of the single-pass storage pipe fitting, and the flow control guide groove is adjusted to the conducting state. At this time, the pressure trigger switch no longer receives the contact signal, and the dissolving medium is no longer directly sprayed out by the electrically driven nozzle, but flows directly from the flow control guide groove to the wall-adhering flow guide cleaning brush head, so that the wall-adhering flow guide brush head is directly sprayed out by the electrically driven nozzle. The wall diversion cleaning brush head directly guides the dissolved medium to the cleaning surface while scraping the narrow diameter cleaning surface in the cleaning barrel. The coal slime adhering to the barrel wall is scraped off by the wall diversion cleaning brush head. By changing the spray mode of the dissolved medium, it is avoided that when the diameter of the diversion barrel is reduced, the sprayed dissolved medium is too concentrated, resulting in the coverage area not meeting the expected requirements. At the same time, since the downward inclination angle of the middle tilting bracket gradually increases when it moves toward the narrow diameter cleaning surface in the barrel, even if the dissolved medium inside the single-pass storage pipe is gradually reduced during cleaning, it can be stably discharged through the flow control guide groove or the electric drive nozzle after the diversion inclination angle increases, thereby ensuring the continuity during operation.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figure 1 - Figure 6 As shown, a rake-type concentrator guide tube cleaning device described in the present invention includes a dissolving medium transport component 1, a central connecting component 2 and an inner diameter telescopic rod 6, the inner diameter telescopic rod 6 is arranged at the bottom of the central connecting component 2, both ends of the central connecting component 2 are rotatably connected to an intermediate tilting bracket 4, one end of the intermediate tilting bracket 4 is detachably connected to a single-pass storage pipe 41, one end of the single-pass storage pipe 41 is provided with an inner diameter contraction component 3 and a wall-attaching cleaning follower component 5, the inner diameter contraction component 3 is slidably connected to the intermediate tilting bracket 4 and the wall-attaching cleaning follower component 5, respectively.

[0028] In this embodiment, a central connection component 2, an inner diameter contraction component 3, an intermediate tilt bracket 4 and an inner diameter telescopic rod 6 are provided as a pushing mechanism for cleaning into the barrel, wherein the inner diameter telescopic rod 6 can be a manual telescopic rod or an electric telescopic rod.

[0029] The central connection component 2 includes a rotating jacket 21, an intermediate transmission seat 22 and a drooping elastic stretching member 23. The inner diameter telescopic rod 6 is fixedly connected to the bottom of the intermediate transmission seat 22. Both rotating jackets 21 are rotatably connected to the intermediate transmission seat 22. The two ends of the drooping elastic stretching member 23 are respectively fixedly connected to the two ends of the single-pass storage pipe 41. The inner diameter contraction component 3 includes a wall-attached diversion cleaning brush head 31 and an embedded transmission rod 32. One end of the embedded transmission rod 32 is bonded and fixed to the wall-attached diversion cleaning brush head 31, and the other end of the embedded transmission rod 32 extends To the inner side of the single-way storage tube 41, and the embedded transmission rod 32 is located at one end of the inner side of the single-way storage tube 41 and a retractable sealing plug 321 is installed. The retractable sealing plug 321 is used to slide and seal the open end of the single-way storage tube 41. The wall-adhering cleaning follower assembly 5 includes a retractable transmission seat 51, a transmission rod 52 and a directional transmission wheel 53. The retractable transmission seat 51 is fixedly connected to the middle tilt bracket 4, one end of the transmission rod 52 is slidably connected to the inner side of the retractable transmission seat 51, and the other end of the transmission rod 52 is rotationally connected to the directional transmission wheel 53.

[0030] In an optional implementation of the present embodiment, an assembly linkage plate 521 is fixedly connected between the embedded transmission rod 32 and the transmission rod member 52, the transmission rod member 52 is arranged parallel to the embedded transmission rod 32, the embedded transmission rod 32 and the transmission rod member 52 slide synchronously through the assembly linkage plate 521, and the sliding extension length of one end of the transmission rod member 52 fixedly connected to the directional transmission wheel 53 is greater than the sliding extension length of the embedded transmission rod 32.

[0031] In this embodiment, the directional transmission wheel 53 is connected to the transmission rod 52, so that the directional transmission wheel 53 can change the sliding guide spacing through the sliding action of the transmission rod 52 and the contraction transmission seat 51 after being squeezed. Even if the middle roll bracket 4 moves to the narrow diameter position in the cylinder, the two left-right symmetrical directional transmission wheels 53 can adapt to the change of spacing as the diameter of the cylinder becomes narrower. At the same time, the length of the transmission rod 52 is longer than the embedded transmission rod 32, so that the directional transmission wheel 53 can still preferentially contact the inner wall of the cylinder as the diameter of the cylinder becomes narrower under the extension action of the transmission rod 52, thereby avoiding sliding interference caused by the embedded transmission rod 32.

[0032] In an optional implementation of this embodiment, a pressure trigger switch 412 is fixedly connected to the inner side of the flow control guide groove 411 , and the pressure trigger switch 412 is connected to the electric drive nozzle 413 by signal.

[0033] In this embodiment, when the inner diameter of the cylinder becomes narrower and the directional transmission wheel 53 pushes the transmission rod 52 to shrink toward the inside of the shrinking transmission seat 51, the embedded transmission rod 32 is synchronously displaced with the transmission rod 52 through the connection of the assembly linkage plate 521, and then the foldable sealing plug 321 is pushed toward the inside of the single-way storage tube 41, so that the foldable sealing plug 321 is away from the open end of the single-way storage tube 41. At this time, the pressure trigger switch 412 no longer receives the release signal of the foldable sealing plug 321, and immediately sends a stop signal to the electric drive nozzle 413, so that after the electric drive nozzle 413 stops, the liquid flows out to the outside through the sliding gap between the flow control guide groove 411 and the foldable sealing plug 321 toward the open end of the single-way storage tube 41, thereby completing the adaptive debugging of the dissolving medium spray mode when the inner diameter of the cylinder is narrowed for cleaning.

[0034] In an optional implementation of the present embodiment, a flow control groove 411 is provided at one end of the single-way storage tube 41 close to the wall-adhering diversion cleaning brush head 31, a retractable sealing plug 321 is slidably connected to the inner side of the flow control groove 411, a side of the retractable sealing plug 321 close to the embedded transmission rod 32 is fixedly connected to a sealing strip, and the inner wall of the single-way storage tube 41 and the flow control groove 411 are sprayed with Teflon coating.

[0035] In this embodiment, the Teflon coating is provided to improve the sliding property of the inner wall of the single-way storage tube 41 and the flow control groove 411, so that when the dissolved medium inside the single-way storage tube 41 flows out to the outside through the single-way storage tube 41 and the flow control groove 411, the flow will not be affected by the viscosity.

[0036] In an optional implementation of this embodiment, the dissolving medium transport component 1 includes a storage barrel 11, an injector 12 and a connecting valve head 13. The storage barrel 11 is mounted on the upper end of the connecting valve head 13. The injector 12 is slidably connected to the storage barrel 11. The storage barrel 11 and the injector 12 are used to inject the dissolving medium into the single-pass storage pipe 41. One end of the middle tilt bracket 4 is also provided with a folding bellows 42. The output end of the folding bellows 42 is threadedly connected to the single-pass storage pipe 41. The other end of the folding bellows 42 is fixedly connected to a two-way connecting valve 43. The input end of the two-way connecting valve 43 is detachably connected to the storage barrel 11. The dissolving medium is a sludge dissolving agent.

[0037] In this embodiment, a one-way valve is arranged between the folded bellows 42 and the one-way storage pipe 41. The one-way valve is arranged to prevent backflow after the dissolved medium in the storage barrel 11 is added. After the dissolved medium in the one-way storage pipe 41 is used up, the two-way connecting valve 43 is connected to the connecting valve head 13, so that the connecting valve head 13 is connected to the one-way storage pipe 41. The dissolving medium in the storage barrel 11 is pushed and pressurized by the pusher 12 to be input into the inner side of the one-way storage pipe 41 through the connecting valve head 13, the two-way connecting valve 43 and the folded bellows 42. The pusher 12 can also use a pump to inject the dissolved medium in the storage barrel 11 into the inner side of the one-way storage pipe 41.

[0038] An anti-slip groove 511 is provided on the inner side of the retractable transmission seat 51, and one end of the transmission rod 52 slides and extends to the inner side of the anti-slip groove 511, and a wall-adhering spring 512 is fixedly connected between the end of the transmission rod 52 located on the inner side of the anti-slip groove 511 and the anti-slip groove 511.

[0039] In this embodiment, the directional transmission wheel 53 applies pressure to the wall-holding spring 512 when the inner diameter of the tube shrinks, so that the wall-holding spring 512 shrinks and drives the transmission rod 52 to slide toward the inside of the shrinking transmission seat 51. The anti-slip groove 511 is used to provide space for the transmission rod 52 to slide and shrink toward the inside of the shrinking transmission seat 51. At the same time, the diameter of the transmission rod 52 extending to one end of the inner side of the shrinking transmission seat 51 is larger than the diameter of the open end of the anti-slip groove 511, which can prevent the transmission rod 52 from directly falling out of the anti-slip groove 511 when it is subjected to the elastic restoring force of the wall-holding spring 512.

[0040] The wall-adhering diversion cleaning brush head 31 is made of a highly water-absorbent material, and the highly water-absorbent material is preferably a melamine resin sponge.

[0041] The working principle and use process of the present invention are as follows: when the intermediate tilt bracket 4 enters the single-pass storage pipe 41, the reaction force generated by the anti-slip groove 511 on the transmission rod 52 causes the directional transmission wheel 53 and the end of the wall-adhering diversion cleaning brush head 31 to contact the inner wall surface of the tube first. And when the intermediate tilt bracket 4 extends from bottom to top into the tube, the transmission seat 51 is contracted to provide a contraction path for the transmission rod 52, so that the single-pass storage pipe 41 can move in the relative direction through the rotation connection between the rotating jacket 21 and the intermediate transmission seat 22, and then the contact distance between the wall-adhering diversion cleaning brush head 31 and the transmission rod 52 and the wall surface can be changed synchronously according to the inner diameter size of the tube, so that the wall-adhering diversion cleaning brush head 31 always adheres to the tube wall during the movement to complete the scraping and cleaning, and remove the attached coal slurry. At the same time, when the middle tilt bracket 4 moves on the wide-diameter cleaning surface in the cylinder, the embedded transmission rod 32 and the folding sealing plug 321 are set to block the single-pass storage pipe 41. At this time, the electric-driven nozzle 413 is used as the spraying end of the dissolving medium, so that a large spraying distance is left between the electric-driven nozzle 413 and the cylinder wall, and the sprayed dissolving medium can cover a large area in the cylinder. When the middle tilt bracket 4 moves to the narrow-diameter cleaning surface in the cylinder, the middle tilt bracket 4 is compressed to produce relative movement, and the directional transmission wheel 53 is squeezed by the cylinder wall to drive the transmission rod 52 to shrink inside the shrinking transmission seat 51, so that the assembly linkage piece 521 synchronously drives the embedded transmission rod 32 to move inside the single-pass storage pipe 41, and the flow control guide groove 411 is adjusted to the conducting state. At this time, the pressure trigger switch 412 moves with the displacement of the foldable sealing plug 321, so that the pressure trigger switch 412 no longer receives the contact signal, and controls the electrically driven nozzle 413 to automatically close when it reaches the narrow diameter cleaning surface in the cylinder. At this time, the dissolving medium inside the single-pass storage tube 41 is no longer directly sprayed out by the electrically driven nozzle 413, but flows directly to the wall-adherent flow-guiding cleaning brush head 31 through the flow control guide groove 411, so that the wall-adherent flow-guiding cleaning brush head 31 directly guides the dissolving medium to the cleaning surface while scraping and cleaning the narrow diameter cleaning surface in the cylinder, and the wall-adherent flow-guiding cleaning brush head 31 guides the dissolving medium to the cleaning surface through the wall-adherent flow-guiding cleaning brush head 31. The flow cleaning brush head 31 scrapes off the coal slime adhering to the cylinder wall, and changes the spraying mode of the dissolved medium to avoid the situation where the dissolved medium sprayed out is too concentrated when the diameter of the guide cylinder is reduced, resulting in the coverage area not meeting the expected requirements. At the same time, since the downward inclination angle of the middle tilting bracket 4 gradually increases when it moves toward the narrow-diameter cleaning surface in the cylinder, even if the dissolved medium inside the single-pass storage pipe 41 gradually decreases during cleaning, it can be stably discharged through the flow control guide groove 411 or the electric-driven nozzle 413 after the diversion inclination angle increases, thereby ensuring the continuity during operation.
