[0012] Preferably, a driving assembly is provided at the upper end of the baffle, and the driving assembly is used to drive the rotating rod to rotate.

[0020] The sludge inside the collection component is introduced into the collection tank. The truncated cone-shaped base can transfer the collected sludge to both sides. When cleaning, the sludge outlet is opened by rotating the closing plate, so the sludge can be cleaned quickly.

[0021] When the sewage flows vertically into the treatment tank through the feed pipe, in order to avoid deformation and damage to the baffle caused by the continuous impact of the sewage, the imported sewage is diverted by the installation block, thereby reducing the impact of the water flow on the baffle; When sewage flows, it will hit the driving blades. The impacted driving blades will rotate, driving the rotating rod to rotate. While quickly diverting the sewage, the sludge will fall onto the baffle, and the rotating baffle will generate centrifugal force, performing differential centrifugal separation on the sludge and sewage, thereby improving the separation efficiency of sludge and sewage.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0026] Reference Figure 1-Figure 9, an integrated device for separating and purifying oily sewage sludge, comprising: a treatment tank 1, a feed pipe 10 fixed at the upper end of the treatment tank 1 and a collection tank 2 arranged at the bottom of the treatment tank 1, the upper end of the treatment tank 1 is arranged in a hemispherical shape, and two outlet pipes 3 are fixedly connected on both sides, an oil-water separation component 6 is arranged at the upper end of the outlet pipe 3, and a filter block 15 is arranged inside the outlet pipe 3; A support assembly 4 is vertically fixedly connected inside the collection tank 2, and a collection assembly 5 is arranged on the upper end of the support assembly 4, and the collection assembly 5 is used to separate and collect sludge; The collecting assembly 5 includes a bottom plate 51, a telescopic rotating member 52, a baffle 53 and a spiral piece 54. The bottom plate 51 is vertically fixedly connected to the upper end of the supporting assembly 4 and is sealingly and slidably arranged inside the processing tank 1. The telescopic rotating member 52 is vertically fixedly connected to the middle part of the top of the bottom plate 51. The middle part of the baffle 53 is fixedly connected to the upper end of the telescopic rotating member 52. The baffle 53 is an arc-shaped plate with a protruding surface facing upward. The spiral piece 54 is sleeved on the telescopic rotating member 52 through a connecting member 8. The spiral piece 54 is made of elastic material, and the middle part is concave downward, and a plurality of filter holes are evenly opened on the surface.

[0027] In the embodiment of the above technical solution, the sewage to be treated is introduced into the treatment tank 1 through the feed pipe 10, and the sludge and water are separated by the filter block 15. A multi-layer filter module (mostly used in the existing mud-water separation) is arranged inside the filter block 15 to separate the sludge and water, and the sludge is confined inside the treatment tank 1. The sludge will settle downward under the action of its own gravity. At the same time, the arc-shaped baffle will drive the sewage to flow around. After the water flow hits the side wall, it will form two upper and lower flow layers. The downward water flow will push the precipitated sludge to the position of the spiral sheet 54, and the sewage will be discharged from the outlet pipes 3 on both sides. At this time, the baffle 53 is located below the feed pipe 10, and the sludge will fall into the collection tank 2 along the arc edge of the baffle 53, and fall on the bottom plate 51, thereby forming the separation of sludge and sewage. The separation of sludge and sewage is located inside the treatment tank 1, and then the sewage will be separated from oil and water through the oil-water separation component 6, and the sludge and oil and water will be separated in different regions, thereby improving the separation efficiency without affecting each other.

[0028] At the same time, since the telescopic rotating member 52 will rotate during the sewage introduction process, the rotating spiral blade 54 will rotate the sludge that falls into the treatment tank 1 and move it downward. The sludge is blocked by the spiral blade 54, thereby preventing the continuously introduced sludge from being impacted and shifting its position, thereby ensuring the sludge collection effect. When the sludge is collected to a certain extent, the baffle 53 is driven downward by contracting the telescopic rotating member 52, and the baffle 53 seals and separates the treatment tank 1. The bottom plate 51 is then driven downward by controlling the support assembly 4 to guide the sludge accumulated on the bottom plate 51 into the collection tank 2, thereby improving the sludge treatment efficiency without stopping the sewage introduction.

[0029] The preferred technical solution in this embodiment is: Reference Figure 1-4 The oil-water separation component 6 includes a connecting end 61, a gas guiding end 62, a reaction spiral tube 63 and a water outlet pipe 64. The connecting end 61 is connected to the upper end of the outlet pipe 3, the gas guiding end 62 is fixedly connected to the side of the connecting end 61, the reaction spiral tube 63 is fixedly connected to the side of the gas guiding end 62, and the water outlet pipe 64 is an inverted U-shaped tube, and one side is connected to the reaction spiral tube 63.

[0030] This device uses flotation separation to separate oil and water. The flotation separation method is to introduce gas, usually air or nitrogen, into the sewage to produce tiny bubbles. These bubbles can attach to oil droplets or suspended particles to form flotation bodies. Due to the buoyancy of the bubbles, these flotation bodies will float to the water surface, thereby achieving the separation of oil and water or suspended matter. The flotation separation method can effectively remove oil, suspended matter and colloid substances in sewage, and is suitable for treating oily sewage of different properties, including emulsified oil, dissolved oil and non-emulsified oil.

[0031] When performing oil-water separation, the outlet pipes 3 vertically arranged on both sides will separate the sludge from the sewage, and the sewage will enter the connecting end 61 through the outlet pipe 3, while the gas guide end 62 is connected to the connecting end 61. When the sewage enters, the gas guide end 62 will introduce gas into the sewage. At the same time, in order to ensure the effect of flotation separation, a spiral tube 63 is set to ensure that the gas is combined with the oil droplets or suspended particles inside the oil and water. At the same time, since the separation process is carried out at both ends at the same time, the sewage introduction speed is controlled to ensure the water inlet speed. At the same time, there is enough space at the upper end of the outlet pipe 64 to separate the bubbles from the liquid.

[0032] The wastewater after oil-water separation is discharged through the outlet end of the outlet pipe 64 to ensure the wastewater treatment efficiency.

[0033] An extraction component 7 is provided at the curved upper end of the outlet pipe 3, and the extraction component 7 is used to extract the flotation body generated by flotation. The extraction component 7 includes an air flotation collection pipe 71 and an extraction terminal 72. The air flotation collection pipe 71 is fixedly connected to the curved upper end of the outlet pipe 3, and the extraction terminal 72 is fixedly installed on the upper end of the air flotation collection pipe 71 for extracting the flotation body.

[0034] After the oil and water are separated, the generated flotation body will be transferred to the space for collecting gas at the top of the water pipe. At the same time, as the gas accumulates, the gas will enter the flotation collection pipe 71, and then the continuously generated flotation body will be extracted through the extraction end 72 to avoid gas accumulation and ensure the rapid separation of oil and water.

[0035] Reference Figure 5-6 The support assembly 4 includes a telescopic support column 41 and a base 42. The base 42 is truncated cone-shaped. The telescopic support column 41 is vertically fixedly connected to the middle of the base 42, and the upper end of the telescopic support column 41 is fixedly connected to the bottom plate 51. A mud outlet is opened on the side of the collection tank 2, and the mud outlet is located on the side of the base 42. A closing plate 11 is rotatably installed on the mud outlet.

[0036] The upper collecting assembly 5 is driven to move up and down by the telescopic support column 41. When the upper collecting assembly 5 collects a large amount of sludge, the telescopic support column 41 is controlled to move downward, so as to introduce the sludge inside the collecting assembly 5 into the collecting tank 2. In this way, the collected sludge can be transferred in time without affecting the introduction of sewage. The truncated cone-shaped base 42 can transfer the collected sludge to both sides. When cleaning, the sludge outlet can be opened by rotating the closing plate 11, so that the sludge can be cleaned quickly.

[0037] Reference Figure 7-8 The telescopic rotating member 52 includes a telescopic bottom tube 521, a sealing block 522 and a rotating rod 523. The telescopic bottom tube 521 is vertically fixedly connected to the middle of the bottom plate 51. The sealing block 522 is sealingly slidably arranged inside the telescopic bottom tube 521 (equivalent to an oil cylinder). The rotating rod 523 is rotatably installed on the sealing block 522, and the upper end of the rotating rod 523 is fixedly connected to the baffle 53.

[0038] Hydraulic oil is arranged inside the telescopic bottom tube 521, and the up and down movement of the sealing block 522 is regulated by the hydraulic bar, thereby driving the rotating rod 523 to move up and down, changing the distance between the baffle 53 and the bottom plate 51, and sealing the upper end of the treatment tank 1 through the baffle 53, which facilitates the discharge of the sludge inside the collection tank 2 and reduces the mixing of sewage.

[0039] Reference Figure 8The connecting member 8 includes a fixed block 81 and a sliding block 82. The fixed block 81 is fixedly connected to the inner side of the upper end of the spiral piece 54 and is fixedly connected to the side of the rotating rod 523. A sliding groove is opened on the side of the rotating rod 523. The sliding block 82 is slidably set inside the sliding groove and is fixedly connected to the bottom side of the spiral piece 54.

[0040] The upper end of the spiral piece 54 is fixed to the rotating rod 523 by the fixing block 81, and the other end of the spiral piece 54 is slidably set on the rotating rod 523 by the sliding block 82. When the rotating rod 523 is telescopically slid inside the telescopic bottom tube 521, the sliding block 82 will be blocked, thereby folding the spiral piece 54 to form a blocking layer to block the sludge collected below and prevent the sludge from leaking out.

[0041] Reference Figure 8 A driving assembly 9 is disposed at the upper end of the baffle 53, and the driving assembly 9 is used to drive the rotating rod 523 to rotate; The driving assembly 9 includes a mounting block 91 and driving blades 92 . The mounting block 91 is fixedly connected to the upper end of the baffle 53 , and the top end is configured to be conical. A plurality of driving blades 92 are annularly fixedly connected to the side of the mounting block 91 .

[0042] After the sewage flows vertically into the treatment tank 1 through the feed pipe 10, in order to avoid deformation and damage to the baffle 53 caused by the continuous impact of the sewage, the introduced sewage is diverted by the mounting block 91, thereby reducing the impact of the water flow on the baffle 53. At the same time, the sewage will hit the driving blade 92 during the flow. The impacted driving blade 92 will rotate, driving the rotating rod 523 to rotate. While quickly diverting the sewage, the sludge will fall onto the baffle 53, and the rotating baffle 53 will generate centrifugal force, driving the water flow to flow quickly to the side. The flowing water flow is impacted and flows downward, thereby accelerating the rapid transfer of sedimentation. At the same time, the baffle 53 blocks the directly impacting water flow, forming an upper guide layer and a lower sedimentation layer, reducing the impact on the sludge that has already settled below, and ensuring the sedimentation effect of the sludge.

[0043] At the same time, the driving component 9 drives the rotating rod 523 to rotate, and drives the spiral piece 54 to rotate. After the sludge falls onto the spiral piece 54, the rotating spiral piece 54 will drive the sludge to move downward, and guide the sludge onto the bottom plate 51. At the same time, the diameter of the spiral piece 54 is consistent with the diameter of the collection tank 2, which ensures that the sludge will not turn up again after moving downward, thereby ensuring the collection of the sludge.

[0044] Reference Fig. 9The baffle plate 53 has two liquid outlets symmetrically formed thereon, and two sealing sheets 12 are symmetrically fixedly connected inside the liquid outlets. Both sealing sheets 12 are arc-shaped sheets, and their close ends are in contact with each other up and down, forming an arc that bulges upward.

[0045] As the sludge accumulates inside the collecting assembly 5, it is necessary to clean the sludge into the collecting tank 2. At this time, by controlling the downward movement of the baffle 53, the bottom surface of the spiral blade 54 is in contact with and squeezed against the sludge layer, so that the moisture inside the sludge layer is squeezed out, and the sewage is discharged through the arc-shaped sealing sheet 12, thereby avoiding a large amount of sewage being mixed in the discharged sludge.

[0046] A plurality of frame blocks 13 are fixedly connected to the edge of the bottom plate 51 , and a sealing ring 14 is fixedly connected to the plurality of frame blocks 13 . The edge of the baffle plate 53 is made of elastic material.

[0047] When the telescopic rotating member 52 drives the baffle 53 to move downward, the baffle 53 contacts the sealing ring 14, so that the baffle 53 forms a sealing layer to prevent the sewage above from entering the collection component 5, and there is enough space inside the processing component to store the collected sludge.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
