Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0021] Example 1, referring to Figures 1 - 3 , this embodiment provides a sludge separation device, including a precipitation frame 1, a bottom plate unit 2 and a sewage discharge unit 5; wherein the precipitation frame 1 is formed by enclosing four plate-shaped parts connected end to end. There is a sedimentation cavity inside the precipitation frame 1. Sewage is statically placed in the sedimentation cavity, and sludge precipitates in the sedimentation cavity, which can realize the preliminary separation of sludge and sewage. Then, the sewage is pumped for further purification, and finally the sludge is removed, and then the precipitation separation operation can be carried out again.

[0022] Among them, the bottom plate unit 2 is installed in the precipitation frame 1. The bottom plate unit 2 includes two partition boards 3 rotatably arranged inside the precipitation frame 1, driving assemblies 4 respectively arranged at the bottoms of the two partition boards 3. The two driving assemblies 4 control the ends of the two partition boards 3 to rotate and contact for sealing. Except for the parts where the two partition boards 3 contact each other, the remaining parts are in sealing contact with the inner wall of the precipitation frame 1. The space between the upper part of the partition board 3 and the inner sides of the four sides of the precipitation frame 1 forms a sedimentation cavity. The sludge in the sewage will fall on the partition board 3 after precipitation in the sedimentation cavity.

[0023] Among them, the sewage discharge unit 5 is installed at the bottom of the sedimentation frame 1. The sewage discharge unit 5 includes a sewage collection rack 6 arranged at the bottom of the sedimentation frame 1, a sewage discharge hole 7 arranged on the sedimentation frame 1 and communicated with the sewage collection rack 6, and a conveying component 8 arranged in the sewage collection rack 6; the sewage collection rack 6 is located below the contact surface of the two partition plates 3, and the conveying component 8 is used to discharge the sludge in the sewage collection rack 6; When the two partition plates 3 are in contact and sealed, the bottom of the sedimentation cavity will be closed. At this time, the sludge can precipitate in the sedimentation cavity. After the sludge precipitates, the sewage is pumped away. At this time, the control chain makes the two driving components 4 work synchronously to control the two partition plates 3 to rotate simultaneously, so that the two partition plates 3 are separated. After the partition plates 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 partition plates 3 and enter the sewage collection rack 6. Both ends of the sewage collection rack 6 are in contact with the inner wall of the sedimentation frame 1. The cross-section of the sewage collection rack 6 is U-shaped. The sludge flowing out from the gap between the partition plates 3 will enter the sewage collection rack 6 and contact the conveying component 8, so as to be discharged from the sewage collection rack 6 by the conveying component 8.

[0024] Among them, the conveying component 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 second driving motor 35 arranged at the end of the conveying shaft 33; the spiral blade 34 is located inside the sewage collection rack 6.

A groove is provided at the end of the first telescopic rod 10 and the bottom of the partition plate 3, and a rotating shaft is provided in the groove. The railing one can be fixed through the rotating shaft. When the first telescopic rod 10 expands and contracts, it can control the partition plate 3 to rotate, so as to control the two partition plates 3 to close and separate, realizing the closing and opening of the bottom of the sedimentation cavity. Among them, there are multiple first telescopic rods 10 and connecting rods 11 to improve the stability of the partition plate 3. The first telescopic rod 10 is made of an electric telescopic rod or a cylinder.

[0026] Furthermore, the partition plate 3 is rotatably connected to the sedimentation frame 1 through a fixed shaft. The peripheral side edges of the partition plate 3 are wrapped with a rubber layer, and the partition plate 3 is in close contact and sealed with the sedimentation frame 1; when the two partition plates 3 are in contact at their ends, the whole is in a V shape. When the two partition plates 3 are in contact and sealed, the V shape can increase the area of the sedimentation cavity.

[0027] The usage process is as follows: First, bring the two partition plates 3 into contact to close the sedimentation cavity, then introduce sewage for sludge sedimentation. After that, pump out the sewage and separate the two partition plates 3 so that the sludge is discharged from the gap between the partition plates 3 into the sewage collection rack 6, and finally is sent out by the rotating spiral blade 34. Then, close the bottom of the sedimentation cavity by closing the two partition plates 3 and inject sewage again for sludge sedimentation.

[0028] Embodiment 2, referring to Figure 4 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a supplementary sealing assembly 9 is provided at the bottom of the partition plate 3, and the end of the supplementary sealing assembly 9 can move relative to the partition plate 3; the ends of the two supplementary sealing assemblies 9 are in contact for sealing, and the two supplementary sealing assemblies 9 are respectively connected to the two driving assemblies 4.

[0029] Among them, the supplementary sealing assembly 9 includes a fixed block 13 provided at the bottom of the partition plate 3, a sliding rod 14 slidably arranged in the fixed block 13, a mounting plate 15 provided at the end of the sliding rod 14, and a sealing strip 16 provided at the end of the mounting plate 15; a plurality of fixed blocks 13 and sliding rods 14 are provided to improve the stability of the mounting plate 15.

[0030] The top of the sealing strip 16 is in contact with the partition plate 3 for sealing, and both sides of the sealing strip 16 are in contact with the sedimentation frame 1 for sealing; the two sealing strips 16 are in contact for sealing; when the two partition plates 3 are in contact for sealing, then control the two mounting plates 15 to approach so that the two sealing strips 16 are in contact for supplementary sealing to improve the sealing effect.

[0031] The other end of the sliding rod 14 is connected to the driving assembly 4. Among them, the driving assembly 4 includes a second telescopic rod 12. The second telescopic rod 12 is installed at the bottom of the partition plate 3, and at the same time, the end of the second telescopic rod 12 is connected to the sliding rod 14. The sliding rod 14 and the mounting plate 15 can be controlled to expand and contract through the second telescopic rod 12, and then the two sealing strips 16 can be controlled to approach and contact for sealing. The second telescopic rod 12 is made of an electric telescopic rod or a cylinder.

[0032] The usage process is as follows: First, bring the two partition plates 3 into contact to close the sedimentation cavity, then bring the two sealing strips 16 closer to contact for supplementary sealing, then introduce sewage for sludge sedimentation. After that, pump out the sewage, and first separate the two sealing strips 16, then separate the two partition plates 3 so that the sludge is discharged from the gap between the partition plates 3 into the sewage collection rack 6, and finally is sent out by the rotating spiral blade 34. Then, close the bottom of the sedimentation cavity by closing the two partition plates 3, then bring the two sealing strips 16 into contact, and finally inject sewage again for sludge sedimentation; First, separating the sealing strip 16 can prevent sludge from adhering to the sealing strip 16 when it falls into the sewage collection rack 6, which affects the sealing effect of the sealing strip 16. When discharging the sludge, the sealing strip 16 retracts behind the contact surface of the partition plate 3, which can effectively prevent the sludge from contacting the sealing strip 16. When the two partition plates 3 are closed, the two sealing strips 16 contact again, increasing the service life of the sealing strip 16.

[0033] Embodiment 3, referring to Figures 5 - 9 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the driving assembly 4 includes a driving part 17 rotatably arranged at one end of the precipitation frame 1, and a supporting part 18 rotatably arranged between the driving part 17 and the other end of the precipitation frame 1; the supporting part 18 is connected to the partition plate 3; The driving part 17 is connected to the sliding rod 14; the driving part 17 controls the rotation of the supporting part 18.

[0034] Among them, the driving part 17 includes a mounting shaft 19 rotatably arranged on the precipitation frame 1, a first driving motor 20 arranged at the end of the mounting shaft 19, a mounting disc 21 arranged at the other end of the mounting shaft 19, and an opening cylinder 22 arranged on the mounting disc 21; among them, the first driving motor 20 is located outside the precipitation frame 1.

[0035] The bottom of the supporting part 18 is located inside the opening cylinder 22; both ends of the opening cylinder 22 can respectively rotate and contact the two sides of the supporting part 18; one end of the opening cylinder 22 is connected to the sliding rod 14 through a first connecting rod 23.

[0036] Furthermore, one end of the opening cylinder 22 is an extrusion end 31, and the other end of the opening cylinder 22 is a limiting end 32. The extrusion end 31 is connected to the sliding rod 14 through a first connecting rod 23; among them, grooves are provided at the ends of the extrusion end 31 and the sliding rod 14, and the first connecting rod 23 is rotatably installed in the grooves through a rotating shaft, so that both ends of the first connecting rod 23 are respectively rotatably connected to the extrusion end 31 and the sliding rod 14; among them, when the opening cylinder 22 rotates, it can control the movement of the first connecting rod 23, thereby driving the sliding rod 14 to move relative to the partition plate 3, so as to control the two sealing strips 16 to extend and approach or contract and separate; when the extrusion end 31 controls the contraction of the sealing strip 16, it can squeeze the supporting part 18 to control the rotation of the supporting part 18, and the limiting end 32 contacts the supporting part 18 to limit the rotation of the supporting part 18 to prevent the supporting part 18 from rotating.

[0037] Furthermore, the support part 18 includes a support shaft 24 rotatably arranged between the mounting disc 21 and the sedimentation frame 1, a plurality of support seats 25 arranged on the support shaft 24, a second connecting rod 26 arranged between the support seat 25 and the partition plate 3, and a reset member 27 arranged between the support seat 25 and the sedimentation frame 1. A groove is provided between the end of the support seat 25 and the partition plate 3. Both ends of the second connecting rod 26 are rotatably connected to the partition plate 3 and the groove of the support seat 25 through a rotating shaft. When the support seat 25 rotates, the second connecting rod 26 can drive the partition plate 3 to rotate, so as to realize the close sealing or separation and opening of the gap between the two partition plates 3.

[0038] Among them, an arc-shaped groove 28 is provided on the mounting disc 21; the reset member 27 includes a fixing plate 29 arranged in the sedimentation frame 1 and a spring 30 arranged between the fixing plate 29 and the support seat 25; the fixing plate 29 passes through the arc-shaped groove 28 and both ends are fixedly connected to the sedimentation frame 1. When the mounting disc 21 rotates, the fixing plate 29 will not interfere with the mounting disc 21 in the arc-shaped groove 28. In the initial state, the support seat 25 supports the second connecting rod 26 under the elastic force of the spring 30, so that the second connecting rod 26 supports the partition plate 3, and the two partition plates 3 are close to and contact each other under the elastic force of the two springs 30.

[0039] In the initial state, the two partition plates 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 cylinder 22 contacts the support seat 25 to support the support seat 25, so as to prevent the partition plate 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 far away from the support seat 25 at this time, and the two sealing strips 16 contact each other at this time to achieve supplementary sealing; During use: when the sludge precipitates in the sedimentation cavity and the sewage is pumped out, the spring 30 pulls the support seat 25 to control the two partition plates 3 to contact. At this time, the partition plates 3 can support the sludge under the elastic force of the spring 30. When it is necessary to discharge the sludge, only need to control the two driving motors 20 to rotate simultaneously. At this time, the rotation directions of the two driving motors 20 are opposite. Under the operation of the driving motors 20, the mounting disc 21 will be driven to rotate, and the mounting disc 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 first connecting rod 23 will pull the sliding rod 14, so that the two sealing strips 16 will be separated first. After the two sealing strips 16 are separated and retracted a certain distance behind the contact part of the two partition plates 3, the extrusion end 31 will contact the support seat 25 and thus 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 second connecting rod 26 will be driven to pull the partition plate 3, so that the two partition plates 3 rotate and separate 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 avoid the sludge adhering to the sealing strips 16 when it falls, ensuring the cleanliness of the sealing strips 16 and improving the service life of the sealing strips 16.

[0040] After the sludge is completely discharged, simply rinse the partition plate 3 to remove the sludge on the partition plate 3. At the same time, control the two driving motors 1 to reverse. The mounting plate 21 will drive the opening cylinder 22 to rotate. At this time, the extrusion end 31 will move away from the support seat 25. Under the elastic force of the spring 30, the support seat 25 always approaches the extrusion end 31. At the same time, the partition plate 3 will rotate until the two partition plates 3 rotate and contact each other. Then 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. At the same time, the limiting end 32 will abut against the support seat 25, and the limiting end 32 can limit the support seat 25. After that, inject sewage into the sediment cavity to separate the sludge again.

[0041] The rest of the structure is the same as that of Embodiment 2.
