[0046] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0047] Example 1, reference Figure 1-Figure 3This embodiment provides a sludge separation device, including a sedimentation frame 1, a bottom plate unit 2 and a sewage discharge unit 5; the sedimentation frame 1 is composed of four plates connected end to end, and a sedimentation cavity is provided inside the sedimentation frame 1. The sewage is placed in the sedimentation cavity, and the sludge is precipitated in the sedimentation cavity, so that the sludge and sewage can be initially separated. The sewage is then extracted for further purification, and finally the sludge is removed, and the sedimentation and separation operation can be carried out again.

[0048] The bottom plate unit 2 is installed in the sedimentation frame 1. The bottom plate unit 2 includes two partitions 3 rotatably arranged inside the sedimentation frame 1, and driving components 4 respectively arranged at the bottom of the two partitions 3. The two driving components 4 control the rotation and contact sealing of the ends of the two partitions 3. Except for the parts that contact each other, the remaining parts of the two partitions 3 are sealed in contact with the inner wall of the sedimentation frame 1. The space above the partition 3 and the inner sides of the four sides of the sedimentation frame 1 constitutes a sedimentation cavity. The sludge in the sewage will fall on the partition 3 after settling in the sedimentation cavity.

[0049] The sewage discharge unit 5 is installed at the bottom of the sedimentation frame 1. The sewage discharge unit 5 includes a sewage collecting frame 6 arranged at the bottom of the sedimentation frame 1, a sewage discharge hole 7 provided on the sedimentation frame 1 and communicating with the sewage collecting frame 6, and a conveying assembly 8 provided in the sewage collecting frame 6; the sewage collecting frame 6 is located below the contact surface of the two partitions 3, and the conveying assembly 8 is used to discharge the sludge in the sewage collecting frame 6;

[0050] When the two partitions 3 are in contact and sealed, the bottom of the sedimentation cavity will be closed. At this time, the sludge can be settled in the sedimentation cavity. After the sludge is settled, the sewage will be pumped away. At this time, the two drive components 4 of the control chain work synchronously to control the two partitions 3 to rotate at the same time, so that the two partitions 3 are separated. After the partitions 3 are separated, the bottom of the sedimentation cavity is opened. At this time, the sludge can flow out from the gap between the two partitions 3 and enter the sewage collecting rack 6, where the two ends of the sewage collecting rack 6 are in contact with the inner wall of the sedimentation frame 1. The cross-section of the sewage collecting rack 6 is U-shaped. The sludge flowing out from the gap between the partitions 3 will enter the sewage collecting rack 6 and contact the conveying component 8, and thus be discharged from the sewage collecting rack 6 by the conveying component 8.

[0051] The conveying assembly 8 includes a conveying shaft 33 rotatably arranged in the sedimentation frame 1, a spiral blade 34 arranged on the conveying shaft 33, and a driving motor 2 35 arranged at the end of the conveying shaft 33; the spiral blade 34 is located inside the sewage collecting frame 6, and the driving motor 2 35 mobilizes the conveying shaft 33 and the spiral blade 34 to rotate to send the sludge falling inside the sewage collecting frame 6 out of the sewage discharge hole 7. A collection device is installed outside the sewage discharge hole 7 to collect the discharged sludge, and the driving motor 2 35 is located outside the sedimentation frame 1.

[0052] Furthermore, the driving assembly 4 is arranged below the partition 3, which includes a telescopic rod 10 installed on the inner wall of the sedimentation frame 1, and a connecting rod 11 arranged between the telescopic rod 10 and the partition 3. The two ends of the connecting rod 11 are rotatably connected to the end of the telescopic rod 10 and the bottom of the partition 3 respectively. A groove is provided at the end of the telescopic rod 10 and the bottom of the partition 3. A rotating shaft is provided in the groove, and the railing can be fixed by the rotating shaft. When the telescopic rod 10 is extended or retracted, the partition 3 can be controlled to rotate, thereby controlling the two partitions 3 to close and separate, thereby realizing the closing and opening of the bottom of the sedimentation cavity. There are multiple telescopic rods 10 and connecting rods 11 to improve the stability of the partition 3. The telescopic rod 10 is made of an electric telescopic rod or a cylinder.

[0053] Furthermore, the partition 3 and the sedimentation frame 1 are rotationally connected through a fixed shaft, and the sides of the partition 3 are wrapped with a rubber layer, so that the partition 3 and the sedimentation frame 1 are fitted and sealed; when the two partitions 3 are in contact at their ends, the whole is V-shaped. When the two partitions 3 are in contact and sealed, the V-shape can increase the area of ​​the sedimentation cavity.

[0054] The usage process is as follows: first, the two partitions 3 are brought into contact to close the sedimentation cavity, then sewage is introduced to precipitate the sludge, then the sewage is pumped out and the two partitions 3 are separated so that the sludge is discharged from the gap between the partitions 3 into the sewage collecting rack 6, and finally sent out by the rotating spiral blades 34, and then the two partitions 3 are closed to close the bottom of the sedimentation cavity and sewage is injected again to precipitate the sludge.

[0055] Example 2, reference Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a supplementary sealing component 9 is provided at the bottom of the partition 3, and the end of the supplementary sealing component 9 can move relative to the partition 3; the ends of the two supplementary sealing components 9 are in contact and sealed, and the two supplementary sealing components 9 are respectively connected to the two driving components 4.

[0056] Among them, the supplementary sealing assembly 9 includes a fixed block 13 arranged at the bottom of the partition 3, a sliding rod 14 slidably arranged in the fixed block 13, a mounting plate 15 arranged at the end of the sliding rod 14, and a sealing strip 16 arranged at the end of the mounting plate 15; wherein the fixed block 13 and the sliding rod 14 are provided in plurality to improve the stability of the mounting plate 15.

[0057] The top of the sealing strip 16 contacts and seals with the partition 3, and the two sides of the sealing strip 16 contact and seal with the precipitation frame 1; the two sealing strips 16 contact and seal; when the two partitions 3 contact and seal, the two mounting plates 15 are controlled to move closer so that the two sealing strips 16 contact and perform supplementary sealing to improve the sealing effect.

[0058] The other end of the slide rod 14 is connected to the drive assembly 4, wherein the drive assembly 4 includes a telescopic rod 2 12, which is installed at the bottom of the partition 3, and the end of the telescopic rod 2 12 is connected to the slide rod 14. The telescopic rod 2 12 can be used to control the extension and retraction of the slide rod 14 and the mounting plate 15, thereby controlling the two sealing strips 16 to approach each other and contact and seal. The telescopic rod 2 12 is made of an electric telescopic rod or a cylinder.

[0059] The use process is as follows: first, the two partitions 3 are brought into contact to close the sedimentation cavity, and then the two sealing strips 16 are brought into contact for additional sealing, and then sewage is introduced to precipitate the sludge. After that, the sewage is pumped out, and the two sealing strips 16 are separated first, and then the two partitions 3 are separated so that the sludge is discharged from the gap between the partitions 3 into the sewage collecting rack 6, and finally sent out by the rotating spiral blades 34. After that, the two partitions 3 are closed to close the bottom of the sedimentation cavity, and then the two sealing strips 16 are brought into contact, and finally sewage is injected again to precipitate the sludge.

[0060] The sealing strip 16 is separated first to prevent the sludge from adhering to the sealing strip 16 and affecting the sealing effect of the sealing strip 16 when it falls into the dirt collecting rack 6. When the sludge is discharged, the sealing strip 16 is retracted behind the contact surface of the partition 3, which can effectively prevent the sludge from contacting the sealing strip 16. When the two partitions 3 are closed, the two sealing strips 16 are contacted again to increase the service life of the sealing strip 16.

[0061] Example 3, reference Figure 5-Figure 9 , which is the third embodiment of the present invention, differs from the second embodiment in that: the driving assembly 4 includes a driving portion 17 rotatably disposed at one end of the sedimentation frame 1, and a supporting portion 18 rotatably disposed between the driving portion 17 and the other end of the sedimentation frame 1; the supporting portion 18 is connected to the partition 3;

[0062] The driving portion 17 is connected to the slide bar 14 ; the driving portion 17 controls the support portion 18 to rotate.

[0063] Among them, the driving part 17 includes a mounting shaft 19 rotatably set on the sedimentation frame 1, a driving motor 20 set at the end of the mounting shaft 19, a mounting disk 21 set at the other end of the mounting shaft 19, and an opening tube 22 set on the mounting disk 21; wherein the driving motor 20 is located outside the sedimentation frame 1.

[0064] The bottom of the support portion 18 is located inside the open tube 22; both ends of the open tube 22 can respectively rotate and contact with both sides of the support portion 18; one end of the open tube 22 is connected to the slide rod 14 through a connecting rod 23.

[0065] Furthermore, one end of the open tube 22 is an extrusion end 31, and the other end of the open tube 22 is a limiting end 32, and the extrusion end 31 is connected to the slide bar 14 through a connecting rod 23; wherein the extrusion end 31 and the end of the slide bar 14 are provided with grooves, and the connecting rod 23 is rotatably installed in the groove through a rotating shaft, so that the two ends of the connecting rod 23 are respectively rotatably connected with the extrusion end 31 and the slide bar 14; wherein when the open tube 22 rotates, it can control the movement of the connecting rod 23, thereby driving the slide bar 14 to move, which is equivalent to the partition 3, thereby controlling the two sealing strips 16 to extend or contract and separate; the extrusion end 31 can squeeze the support part 18 to control the rotation of the support part 18 when controlling the contraction of the sealing strip 16, and the limiting end 32 contacts the support part 18 to limit the support part 18 to prevent the support part 18 from rotating.

[0066] Furthermore, the support portion 18 includes a support shaft 24 rotatably arranged between the mounting plate 21 and the sedimentation frame 1, a plurality of support seats 25 arranged on the support shaft 24, a connecting rod 26 arranged between the support seat 25 and the partition 3, and a reset member 27 arranged between the support seat 25 and the sedimentation frame 1, wherein a groove is provided between the end of the support seat 25 and the partition 3, and the two ends of the connecting rod 26 are respectively rotatably connected to the grooves of the partition 3 and the support seat 25 through a rotating shaft, wherein when the support seat 25 rotates, the connecting rod 26 can drive the partition 3 to rotate, thereby realizing the close sealing or separation opening gap between the two partitions 3.

[0067] Among them, an arc-shaped groove 28 is provided on the mounting disk 21; the reset member 27 includes a fixed plate 29 arranged in the sedimentation frame 1, and a spring 30 arranged between the fixed plate 29 and the support seat 25; the fixed plate 29 passes through the arc-shaped groove 28 and is fixedly connected to the sedimentation frame 1 at both ends. When the mounting disk 21 rotates, the fixed plate 29 will not interfere with the mounting disk 21 in the arc-shaped groove 28. In the initial state, the support seat 25 supports the connecting rod 26 under the elastic force of the spring 30, so that the connecting rod 26 supports the partition 3, and the two partitions 3 are close to each other under the elastic force of the two springs 30.

[0068] In the initial state, the two partitions 3 are in contact and sealed under the elastic force of the two springs 30. At this time, the limiting end 32 of the opening tube 22 contacts the support seat 25 to support the support seat 25, thereby preventing the partition 3 from being pushed open when sewage is injected into the sedimentation cavity; when the limiting end 32 contacts the support seat 25, the extrusion end 31 is away from the support seat 25, and the two sealing strips 16 contact each other to achieve supplementary sealing;

[0069] During use: when the sludge settles in the sedimentation cavity and the sewage is pumped out, the spring 30 pulls the support seat 25 to control the two partitions 3 to contact each other. At this time, the partition 3 can support the sludge under the elastic force of the spring 30. When the sludge needs to be discharged, it is only necessary to control the two drive motors 20 to rotate at the same time. At this time, the rotation directions of the two drive motors 20 are opposite. Under the operation of the drive motor 20, the mounting plate 21 will be driven to rotate, and the mounting plate 21 will drive the opening cylinder 22 to rotate. First, the extrusion end 31 will approach the support seat 25. When the extrusion end 31 approaches the support seat 25, the connecting rod 23 will pull the slide bar 14. The two sealing strips 16 are separated first. When the two sealing strips 16 are separated and retracted a distance behind the contact part of the two partitions 3, the extrusion end 31 will contact the support seat 25 to push the support seat 25 to rotate. When the support seat 25 rotates, the spring 30 will be compressed, and at the same time, the connecting rod 26 will be driven to pull the partition 3, so that the two partitions 3 are rotated and separated to open a gap. At this time, the sludge can fall from the gap and be rotated and sent out by the spiral blade 34; the two sealing strips 16 are separated first to prevent the sludge from adhering to the sealing strip 16 when it falls, thereby ensuring the cleanliness of the sealing strip 16 and increasing the service life of the sealing strip 16.

[0070] When the sludge is discharged, the partition 3 is simply flushed to remove the sludge on the partition 3, and the two drive motors 20 are controlled to reverse at the same time. The mounting plate 21 will drive the opening cylinder 22 to rotate. At this time, the extrusion end 31 will separate relative to the support seat 25, and under the elastic force of the spring 30, the support seat 25 is always close to the extrusion end 31, and the partition 3 will rotate until the two partitions 3 rotate and contact, and the support seat 25 will stop rotating. At this time, the extrusion end 31 rotates away from the support seat 25 until the two sealing strips 16 contact and seal, and at the same time, the limit end 32 will resist the support seat 25. The limit end 32 can limit the support seat 25, and then sewage is injected into the sedimentation cavity to separate the sludge again.

[0071] The remaining structures are the same as those of Example 2.

[0072] 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.
