DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] It will be understood that the terms "first," "second," etc. used herein may be used to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0034] like Figure 1 、 Figure 3 and Figure 4 As shown, in one embodiment, a river sludge treatment device for ecological environment protection is proposed, the device includes four stations: a conveying station a, a collecting station b, a resetting station c, and a waiting station d, and also includes:

[0035] Main frame 1: including a mounting platform 101 provided on the main frame 1;

[0036] Filter mechanism 2: includes four inflow pipes 201 mounted on the mounting platform 101. A three-way fixing block 202 is fixedly mounted on the surface of each inflow pipe 201. A filter screen 203 is slidably connected to the inner wall of the three-way fixing block 202. An outflow pipe 204 is fixedly mounted on the surface of the three-way fixing block 202. The inflow pipes 201, the three-way fixing block 202, and the outflow pipes 204 are internally connected.

[0037] Moving mechanism 3: used to cooperate with the chute mechanism 4 to drive the inflow pipe 201 to revolve;

[0038] Rotating mechanism 5: used to cooperate with switching mechanism 6 to open the passage of three-way fixing block 202;

[0039] Pipeline mechanism 7: used to cooperate with negative pressure mechanism 8 to continuously extract sludge.

[0040] In practical application of the embodiment of the present invention, when sludge is extracted, Figure 1 As shown, at this time, the sludge is transported from the pipe mechanism 7 to the inflow pipe 201 through the negative pressure mechanism 8. At this time, the sludge passes through the three-way fixed block 202 in sequence, and the solid metal is blocked at the position of the filter mesh 203 by the filtering effect of the filter mesh 203, thereby achieving the purpose of automatically filtering the solid metal, and the sludge is extracted through the outflow pipe 204. When the impurities in the filter mesh 203 reach a certain amount, as shown in FIG. Figure 3 As shown, from Figure 3 Looking from the front direction, at this time, due to the constant negative pressure suction of the negative pressure mechanism 8, the resistance generated by the solid metal at the position of the filter 203 increases, and the filter 203 is driven to move obliquely to the upper left, driving the moving mechanism 3 to move synchronously. At this time, the moving mechanism 3 is separated from the limiting effect of the chute mechanism 4, as shown in FIG. Figure 4 As shown, the three-way fixed block 202 moves from the conveying station a to the collecting station b under the action of the gravity of the internal sludge. At this time, the new three-way fixed block 202 moves from the waiting station d to the conveying station a, and then the sludge extraction continues. Because the three-way fixed block 202 moves from the conveying station a to the collecting station b under the action of the pipeline mechanism 7, it will gradually disconnect from the main channel, and the new three-way fixed block 202 moves from the waiting station d to the conveying station a and gradually connects to the main channel The negative pressure mechanism 8 is internal, thereby ensuring continuous operation of the negative pressure mechanism 8 and avoiding the phenomenon of empty suction, thereby achieving the purpose of continuous sludge extraction. At the same time, when moving from the conveying station a to the collecting station b, the other channel of the three-way fixed block 202 is driven to open under the action of the rotating mechanism 5 and the switching mechanism 6. Under the action of the sludge's own gravity and the centrifugal force of rotation, the solid metal on the filter screen 203 and the sludge fall into the rotating mechanism 5, thereby achieving the purpose of automatically removing the solid metal and avoiding affecting the sludge extraction.

[0041] like Figure 3 As shown, as a preferred embodiment of the present invention, the moving mechanism 3 includes a moving slide rod 301 fixedly connected to the filter screen 203, the moving slide rod 301 passes through the rotating mechanism 5 and is slidably connected to the rotating mechanism 5, and the end of the moving slide rod 301 away from the filter screen 203 is fixedly connected to a connecting block 303, the connecting block 303 is connected to the rotating mechanism 5 through a compression spring 302, and a sliding rod 304 is fixedly installed on the surface of the connecting block 303.

[0042] In practical application, the embodiment of the present invention is as follows: Figure 3 As shown, from Figure 3 When the filter screen 203 moves obliquely to the upper left, the movable slide bar 301 is driven to move synchronously. The movement of the movable slide bar 301 drives the sliding bar 304 to move in the chute mechanism 4 through the connection of the mechanism. At the same time, the compression spring 302 is compressed. At this time, when the movable slide bar 301 moves to the point where it is no longer limited by the chute mechanism 4, the gravity of the sludge inside the three-way fixed block 202 drives the three-way fixed block 202 to revolve from the conveying station a to the collecting station b. When it moves to the collecting station b, it is out of the negative After the negative pressure suction of the pressure mechanism 8 acts, the filter screen 203 is reset under the elastic potential energy of the compression spring 302. At this time, the sliding rod 304 returns to the chute mechanism 4. When the three-way fixed block 202 at the transfer station d moves to the conveying station a, the sliding rod 304 is limited by the chute mechanism 4 and no longer causes the three-way fixed block 202 to revolve. At this time, the sludge extraction operation continues until the new filter screen 203 moves, and the same action is repeated again, thereby achieving the purpose of automatic and rapid cycle of sludge extraction to avoid the influence of solid metal on extraction.

[0043] like Figure 5 and Figure 6 As shown, as another preferred embodiment of the present invention, the slide mechanism 4 includes a slide circular plate 401 fixedly mounted on the mounting platform 101, and the surface of the slide circular plate 401 is rotatably connected to a block wheel 404, a plurality of blocks are provided on the block wheel 404, and a circular track is formed between the block wheel 404 and the slide circular plate 401, and the surface of the slide circular plate 401 is provided with a vertical slide 405, an outer slide 402 and a horizontal slide 403 that cooperate with the sliding rod 304 and are sequentially connected, and the other ends of the horizontal slide 403 and the vertical slide 405 are both connected to the circular track.

[0044] In practical application of the embodiment of the present invention, when the sliding rod 304 is pulled by the moving sliding rod 301, as shown in FIG. Figure 5As shown, at this time, the sliding rod 304 slides in the horizontal slide groove 403, and the contact end of the sliding rod 304 and the horizontal slide groove 403 is provided with a rolling ball, thereby converting the sliding friction into rolling friction, thereby increasing the service life of the device. When the sliding rod 304 slides to the circumferential track between the block wheel 404 and the slide groove circular plate 401, the block wheel 404 is driven to revolve through the sliding rod 304 under the action of the gravity of the three-way fixed block 202, so that the three-way fixed block 202 moves from the conveying station a to the collecting station b. When it moves to the collecting station b, as shown in FIG. Figure 6 As shown, at this time, due to the suction effect of the negative pressure mechanism 8 being separated from the inside of the three-way fixing block 202, the sliding rod 304 moves into the vertical slide groove 405 under the elastic action of the compression spring 302, so that the sliding rod 304 revolves in the outer slide groove 402 during the later cycle, and the sliding rod 304 at the transfer station d moves to the horizontal slide groove 403 at the conveying station a, so that the sliding rod 304 is limited again, ensuring the cyclic operation of sludge extraction and improving the sludge extraction efficiency.

[0045] like Figure 3 and Figure 7 As shown, as another preferred embodiment of the present invention, the rotating mechanism 5 includes four rotating gears 501 mounted on the mounting platform 101, and a driving bevel gear 502 is fixedly mounted on the surface of each rotating gear 501. The driving bevel gear 502 is rotatably connected to the surface of the recovery elbow 507, and the recovery elbow 507 is fixedly connected to the surface of the three-way fixing block 202. The driving bevel gear 502 is engaged with the driven bevel gear disc 503, and the driven bevel gear disc 503 is provided with two arc grooves 504. The trajectory radius of the arc groove 504 gradually increases, and each Each arc groove 504 cooperates with the linkage slide rod 505, and a closing block 506 is fixedly installed on the surface of the linkage slide rod 505. The closing block 506 passes through the recovery elbow 507 and is slidingly connected to the recovery elbow 507. A semicircular hole with the same diameter as the movable slide rod 301 is opened on the closing block 506, and the driven bevel gear plate 503 is rotatably connected to the recovery elbow 507. The other ends of the four recovery elbows 507 are fixedly connected to the linkage rotating plate 508, and the linkage rotating plate 508 is slidably connected to the collection tube 509, and the collection tube 509 is provided with a pipe opening.

[0046] In practical application of the embodiment of the present invention, when moving from the conveying station a to the collecting station b, as shown in FIG. Figure 3As shown, at this time, the rotating gear 501 is synchronously revolving, and the rotating gear 501 is driven to rotate by the cooperation of the rotating gear 501 and the switching mechanism 6 from the conveying station a to the collecting station b. At this time, the rotation of the rotating gear 501 drives the driven bevel gear plate 503 to rotate through the action of the bevel gear set. It should be noted here that when the three-way fixing block 202 at the conveying station a moves to the collecting station b, when the three-way fixing block 202 is disconnected from the main channel, the interior is closed at this time, and the rotating gear 501 is driven to rotate under the action of the rotating gear 501 and the switching mechanism 6, as shown in FIG. Figure 7 As shown, the arc groove 504 opened on the driven bevel gear disc 503 drives the linkage slide bar 505 to move away from the central axis of the driven bevel gear disc 503. At this time, the movement of the linkage slide bar 505 drives the closing block 506 to connect the recovery elbow 507 with the inside of the three-way fixed block 202. At this time, the solid metal and part of the sludge blocked by the filter screen 203 flow from the recovery elbow 507 to the collection barrel 509 under the action of gravity and the centrifugal force of the revolution, thereby achieving the purpose of automatically cleaning the solid metal. When the cycle is carried out next time, that is, when it moves from the collection station b to the reset station c, the rotating gear 501 rotates again and drives the rotating gear 501 to reverse under the action of the switching mechanism 6. At this time, the reversal of the rotating gear 501 drives the closing block 506 to move in the opposite direction, and then the channel of the recovery elbow 507 is closed through the closing block 506, thereby ensuring the normal use of the subsequent re-circulation.

[0047] like Figure 8 and Figure 10 As shown, as another preferred embodiment of the present invention, the switching mechanism 6 includes a switching turntable 601 fixedly connected to the slide groove circular plate 401, and the switching turntable 601 is provided with an inner switching tooth 602 and an outer switching tooth 603 that cooperate with the rotating gear 501, and the radius of the inner switching tooth 602 is smaller than the radius of the outer switching tooth 603.

[0048] In practical application of the embodiment of the present invention, when moving from the conveying station a to the collecting station b, after the three-way fixing block 202 is disconnected from the negative pressure channel, as shown in FIG. Figure 10 As shown, at this time, the rotating gear 501 is engaged with the inner switching tooth 602, and the rotating gear 501 is driven to rotate by the revolution, thereby driving the two closing blocks 506 to open the connection channel between the recovery elbow 507 and the three-way fixing block 202 through the action of the rotating mechanism 5. At this time, the solid metal flows into the rotating mechanism 5 under the action of gravity and centrifugal force. When it moves from the collection station b to the reset station c, the rotating gear 501 is engaged with the switching turntable 601. At this time, the rotating gear 501 is reversed, thereby driving the closing block 506 to close the connection channel between the recovery elbow 507 and the three-way fixing block 202, thereby ensuring the next recycling use.

[0049] like Figure 2 、 Figure 8 and Figure 9 As shown, as another preferred embodiment of the present invention, the pipeline mechanism 7 includes a mud suction pipe 701 that passes through the mounting platform 101 and is fixedly connected to the mounting platform 101, an open groove 702 is provided on the surface of the mud suction pipe 701, a fixed block 703 is fixedly installed on the surface of the mud suction pipe 701, an arc-shaped notch is provided on the fixed block 703, a rotating cylinder 704 is rotatably installed on the surface of the mud suction pipe 701, the rotating cylinder 704 is rotatably connected to the fixed block 703, the surface of the rotating cylinder 704 passes through the switching turntable 601 and is rotatably connected to the switching turntable 601, one end of the outflow pipe 204 is connected to the rotating cylinder 704, and one end of the inflow pipe 201 is connected to the rotating cylinder 704.

[0050] In actual application of the embodiment of the present invention, when the sludge is extracted, the sludge suction pipe 701 is inserted into the sludge underwater, and the negative pressure mechanism 8 starts to move so that negative pressure is generated inside the device to extract the sludge. When the solid metal blocks the filter screen 203, the moving mechanism 3 is caused to revolve under the action of the chute mechanism 4. Figure 2 As shown, at this time, the revolution of the three-way fixed block 202 drives the rotating cylinder 704 to rotate synchronously, as shown in FIG. Figure 9 As shown, due to the action of the opening groove 702, the inflow pipe 201 at the conveying station a is separated from the opening groove 702, and the inflow pipe 201 at the collecting station b is gradually connected with the opening groove 702. At the same time, through the arc-shaped notch set on the fixed block 703, the outflow pipe 204 at the conveying station a is separated from the arc-shaped notch, and the outflow pipe 204 at the collecting station b is connected with the arc-shaped notch, thereby avoiding the internal closed idling of the negative pressure mechanism 8 and achieving uninterrupted cyclic extraction operation.

[0051] like Figure 2 As shown, as another preferred embodiment of the present invention, the negative pressure mechanism 8 includes a negative pressure pump 801 fixedly mounted on the mounting platform 101, and an output pipe 802 and an input pipe 803 are fixedly mounted at both ends of the negative pressure pump 801, the input pipe 803 is rotatably connected to the surface of the rotating cylinder 704, and the input pipe 803 is fixedly connected to the surface of the switching turntable 601.

[0052] In practical application, the embodiment of the present invention is as follows: Figure 2 As shown, when the sludge is extracted, the negative pressure pump 801 starts to run, thereby generating negative pressure inside the input pipe 803 and positive pressure inside the output pipe 802, thereby extracting the sludge from the sludge suction pipe 701 to the other end of the output pipe 802 for collection, thereby achieving the purpose of automatically extracting the sludge.
