DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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.

[0017] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0018] 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: The main frame 1 includes a mounting platform 101 disposed on the main frame 1; Filter mechanism 2: comprises four inflow pipes 201 mounted on the mounting platform 101, each inflow pipe 201 is fixedly mounted with a three-way fixing block 202 on its surface, 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, and the interiors of the inflow pipe 201, the three-way fixing block 202 and the outflow pipe 204 are connected; Moving mechanism 3: used to cooperate with the chute mechanism 4 to drive the inflow pipe 201 to revolve; Rotating mechanism 5: used to cooperate with the switching mechanism 6 to open the passage of the three-way fixing block 202; Pipeline mechanism 7: used to cooperate with negative pressure mechanism 8 to continuously extract sludge.

[0019] 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 pipeline mechanism 7 to the inflow pipeline 201 through the negative pressure mechanism 8. At this time, the sludge passes through the three-way fixing block 202 in sequence, and the solid metal is blocked at the position of the filter screen 203 through the filtering effect of the filter screen 203, thereby achieving the purpose of automatically filtering the solid metal, and the sludge is extracted through the outflow pipeline 204. When the impurities in the filter screen 203 reach a certain amount, as shown in FIG. Figure 3 As shown, from Figure 3 From the front view, at this time, the negative pressure suction force of the negative pressure mechanism 8 is constant, but the resistance generated by the solid metal at the position of the filter screen 203 increases, and at this time, the filter screen 203 is driven to move obliquely to the upper left, and the moving mechanism 3 is driven to move synchronously. At this time, the moving mechanism 3 is separated from the limiting effect of the chute mechanism 4, such as Figure 4 As shown, the three-way fixed block 202 moves from the conveying station a to the collecting station b under 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 is continuously extracted. 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 internally provided, thereby ensuring continuous operation of the negative pressure mechanism 8 and avoiding the phenomenon of empty suction, so as to achieve the purpose of continuously extracting the sludge. At the same time, when moving from the conveying station a to the collecting station b, the other channel of the three-way fixing 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.

[0020] 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.

[0021] 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 moving slide bar 301 is driven to move synchronously. The movement of the moving slide bar 301 drives the slide bar 304 to move in the slide slot mechanism 4 through the connection of the mechanism. At the same time, the compression spring 302 is compressed. At this time, when the moving slide bar 301 moves to the point where it is no longer limited by the slide slot mechanism 4, the three-way fixed block 202 is driven to revolve from the conveying station a to the collecting station b under the gravity of the sludge inside the three-way fixed block 202. 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 slide groove 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 slide groove 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 extraction of sludge and avoiding the influence of solid metal on extraction.

[0022] 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 table 101, the surface of the slide circular plate 401 is rotatably connected to a block wheel 404, a plurality of blocks are arranged 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 which 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.

[0023] In actual 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 5 As 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, so as to convert the sliding friction into rolling friction, thereby increasing the service life of the device. When the sliding rod 304 slides to the circular track between the block wheel 404 and the slide groove circular plate 401, at this time, under the action of the gravity of the three-way fixed block 202, the sliding rod 304 drives the block wheel 404 to revolve, 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 6As shown, at this time, due to the suction effect of the negative pressure mechanism 8 that is 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.

[0024] 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 installed on the mounting platform 101, and the surface of each rotating gear 501 is fixedly installed with an active bevel gear 502, the active bevel gear 502 is rotatably connected to the surface of the recovery elbow 507, the recovery elbow 507 is fixedly connected to the surface of the three-way fixing block 202, the active bevel gear 502 is meshed with the driven bevel gear disc 503, and the driven bevel gear disc 503 is provided with two arc grooves 504, and 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 slidably 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. 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. The linkage rotating plate 508 is slidably connected to the collection tube 509, and the collection tube 509 is provided with a pipe opening.

[0025] 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 3 As 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 7As shown, the arc groove 504 opened on the driven bevel gear disc 503 drives the linkage slide rod 505 to move away from the central axis of the driven bevel gear disc 503. At this time, the movement of the linkage slide rod 505 drives the closing block 506 to connect the recovery elbow 507 with the inside of the three-way fixing 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 next cycle is carried out, that is, when it moves from the collection station b to the reset station c, the rotating gear 501 revolves 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.

[0026] like Figure 8 and Fig.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.

[0027] In actual 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. Fig.10 As shown, at this time, the rotating gear 501 is meshed with the inner switching tooth 602, and the rotating gear 501 is driven to rotate by the revolution, so that the two closing blocks 506 are driven by the action of the rotating mechanism 5 to open the connection channel between the recovery elbow 507 and the three-way fixing block 202. 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 meshed 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.

[0028] like Figure 2 , Figure 8 and Fig. 9As shown, as another preferred embodiment of the present invention, the pipeline mechanism 7 includes a mud suction pipeline 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 pipeline 701, a fixed block 703 is fixedly installed on the surface of the mud suction pipeline 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 pipeline 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 pipeline 204 is connected to the rotating cylinder 704, and one end of the inflow pipeline 201 is connected to the rotating cylinder 704.

[0029] 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 revolves 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 perform synchronous revolution, as shown in FIG. Fig. 9 As shown, due to the effect of the opening groove 702, the inflow pipe 201 at the conveying station a is separated from the opening groove 702, while 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, while 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.

[0030] 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 respectively 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.

[0031] 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.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
