Technical Field
[0001] The utility model relates to the field of oil-liquid separation, in particular to a solid-oil-liquid separation system. Background Art
[0002] Oil-water mixtures, when directly discharged or leaked into the environment, can cause serious pollution to soil, water, and organisms. By separating oil from water, the grease and pollutants can be removed, reducing the impact on the environment and protecting the health of the ecosystem.
[0003] A centrifuge is typically used to separate oil and water. Existing centrifuges, such as those described in patent application number CN202311538176.8, place the oil-water mixture in a centrifugal chamber, which rotates with it. Due to the different densities of oil and water, the mixture separates during rotation. However, many oil-water mixtures often contain solid waste, which also has a high density. This can cause a significant amount of solid waste to be carried in the water after centrifugation.
[0004] Therefore, how to prevent the water obtained after centrifugal separation from carrying a large amount of solid waste residue is a technical problem that needs to be solved urgently. Utility Model Content
[0005] The purpose of the utility model is to overcome the above technical deficiencies and propose a solid-oil-liquid separation system to solve the technical problem in the prior art of how to avoid a large amount of solid waste residue being entrained in the water obtained after centrifugal separation.

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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.
[0024] In order to solve the technical problem of how to avoid a large amount of solid waste being entrained in the water obtained after centrifugal separation, the utility model provides a solid-oil-liquid separation system that can separate solids, oil and water from each other, thereby avoiding a large amount of solid waste being entrained in the water obtained after centrifugal separation.
[0025] It should be noted that the solid-oil-liquid separation system of the present invention is used for but not limited to waste liquid recovery, etc. For the sake of convenience, in the present invention, only the application of the solid-oil-liquid separation system to waste liquid recovery is used as an example for explanation. The principle of applying the solid-oil-liquid separation system to other types of equipment is essentially the same as the principle applied to waste liquid recovery, so they will not be described one by one here.
[0026] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a solid-oil-liquid separation system in one embodiment of the present invention. The solid-oil-liquid separation system includes a solid-liquid separation assembly 100 and an oil-water separator 200. The solid-liquid separation assembly 100 includes a settling tank 110 and a filter 120. The settling tank 110 has a liquid outlet 111 at one end. The filter 120 is installed at the liquid outlet 111 to prevent solid residue from passing through the liquid outlet 111. The oil-water separator 200 receives the liquid discharged from the liquid outlet 111 and separates the water and oil in the liquid.
[0027] In this embodiment, the liquid to be treated is first introduced into a sedimentation tank 110. Solid impurities entrained in the liquid settle within the tank. Filter 120 prevents solid residue from passing through liquid outlet 111. The oil-water mixture is then introduced through outlet 111 into an oil-water separator 200, which separates the water and oil. This solid-oil-liquid separation system can separate solids, oil, and water, preventing the entrainment of large amounts of solid waste residue in the water obtained after centrifugal separation.
[0028] In some embodiments, a slag outlet 112 is formed at the bottom of the sedimentation tank 110 , and a slag outlet 112 is equipped with a slag valve 113 .
[0029] In this embodiment, since the solid waste residue is precipitated in the sedimentation tank 110, the solid waste residue will accumulate at the bottom of the sedimentation tank 110. When the solid waste residue in the sedimentation tank 110 needs to be cleaned, the slag discharge valve 113 can be opened to discharge the solid waste residue from the slag discharge port 112.
[0030] In some embodiments, the bottom end of the sedimentation tank 110 has a guide slope, and the guide slope is inclined toward the slag outlet 112 .
[0031] In this embodiment, the guide slope is inclined toward the slag outlet 112 . Under the guiding action of the guide slope, the solid waste slides along the guide slope, thereby accumulating around the slag outlet 112 , so that the solid waste is discharged from the slag outlet 112 .
[0032] In some embodiments, the liquid outlet 111 defines a mounting groove 1111 , and the filter device 120 is embedded in the mounting groove 1111 .
[0033] In this embodiment, the installation groove 1111 can fix the filter device 120, so that the filter device 120 can be more stably installed in the liquid outlet 111.
[0034] Any filter device 120 that can filter solid waste is feasible. In some embodiments, the filter device 120 includes a filter screen 121 and a support frame 122 . The support frame 122 surrounds the filter screen 121 and is embedded in the installation groove 1111 .
[0035] In this embodiment, the support frame 122 is embedded in the installation groove 1111, so that the filter 121 can be installed at the liquid outlet 111. The filter 121 can allow liquid to pass through the filter 121 and pass through the liquid outlet 111, while blocking solid waste in the sedimentation tank 110.
[0036] In some embodiments, the filtering device 120 further includes a bag filter 123 . The bag filter 123 is installed at the liquid outlet 111 , and the bag filter 123 is disposed between the filter screen 121 and the oil-water separator 200 .
[0037] In this embodiment, the bag filter 123 has a better filtering effect, and the solid impurities are filtered through the filter 121 and the bag filter 123 in sequence, thereby further reducing the probability of solid impurities passing through the liquid outlet 111.
[0038] In some embodiments, the solid-liquid separation assembly 100 further includes a feed pump 130 , which is used to transport the liquid in the sedimentation tank 110 to the liquid outlet 111 .
[0039] In this embodiment, the feed pump 130 can extract the liquid in the sedimentation tank 110 and transport the liquid to the liquid outlet 111 .
[0040] In some embodiments, the settling tank 110 is a stainless steel settling tank 110 .
[0041] In this embodiment, since the settling box 110 is made of stainless steel, the settling box 110 has better corrosion resistance.
[0042] In some embodiments, the solid-liquid separation component 100 also includes a discharge component 300, which includes a pushing screw 310 and a motor 320. The pushing screw 310 is rotatably installed at the bottom end of the sedimentation box 110, and one end of the pushing screw 310 is mounted above the slag outlet 112. The motor 320 is connected to the pushing screw 310 to drive the pushing screw 310 to rotate.
[0043] In this embodiment, the motor 320 drives the pushing screw 310 to rotate. Rotating the pushing screw 310 can push the solid waste residue, so that the solid waste residue can be discharged through the residue outlet 112.
[0044] Any implementation of the oil-water separator 200 that can separate oil and water is feasible. In some embodiments, the oil-water separator 200 is preferably a centrifugal separator.
[0045] In order to better understand the present invention, the following Figures 1 to 2 The technical solution of the utility model is described in detail:
[0046] First, the liquid to be treated is introduced into the sedimentation tank 110. Solid impurities entrained in the liquid will settle within the sedimentation tank 110. The feed pump 130 extracts the liquid from the sedimentation tank 110 and delivers it to the liquid outlet 111. The liquid is then filtered through the filter screen 121 and the bag filter 123, preventing solid residue from passing through the liquid outlet 111. The oil-water mixture is then introduced through the liquid outlet 111 into the oil-water separator 200, which separates the water and oil. This solid-oil-liquid separation system can separate solids, oil, and water, preventing the entrainment of large amounts of solid waste residue in the water obtained after centrifugal separation.
[0047] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
