Description

Technical Field

[0001] This utility model relates to the technical field of high-dryness oil sludge separation devices, specifically a high-dryness oil sludge separation device with scum filtration function. Background Technology

[0002] In the oil sludge treatment industry, horizontal screw centrifugal oil sludge high-dryness separation devices are widely used for the separation of oil, water, and solid materials in oil sludge. The working principle is that the motor drives the inner cylinder to rotate at high speed to generate centrifugal force, which causes the components of different densities in the oil sludge to separate into layers. The heavier solid materials are concentrated towards the conical end of the inner cylinder under the action of centrifugal force, and then pushed out from the dry material outlet by the spiral blades. The liquid materials move away from the conical end under the compression of the solid materials. Under the action of centrifugal force, the denser water in the liquid material is located on the outside, and the less dense oil is located on the inside. The two are discharged from the corresponding liquid outlets to achieve the initial separation of oil, water, and solid materials.

[0003] Currently, the structural design of existing horizontal screw centrifugal oil-sludge high-dryness separation devices only focuses on the centrifugal stratification separation of oil, water, and solid materials. They do not have a dedicated filtration device for the scum on the inside of the oil. Under the action of centrifugal force, the scum will be located on the inside of the oil, causing the scum to be discharged from the oil outlet along with the oil, affecting the purity of the separated oil. An additional scum removal process is required for secondary treatment of the oil. At the same time, if the scum accumulates inside the equipment for a long time, it can easily block the oil outlet, resulting in a decrease in the separation efficiency of the equipment.

[0004] Therefore, a high-dry separation device for oil sludge with scum filtration function is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil sludge high-dryness separation device with scum filtration function. Through the filter chamber and the first liquid outlet chamber, it can specifically filter the scum located inside the oil after centrifugal separation, intercept the scum to prevent it from being discharged with the oil, improve the purity of the separated oil, and eliminate the need for additional scum removal process for secondary oil treatment. This can solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes an outer cylinder, an inner cylinder, a feed pipe, and a filter chamber. The feed pipe is inserted into the inner cylinder, and one end of the feed pipe inserted into the inner cylinder is rotatably connected to the inner cylinder. The outer cylinder is sleeved on the outside of the inner cylinder, and the outer cylinder is rotatably connected to the inner cylinder. The outer cylinder and the feed pipe are fixedly connected by a fixing bracket. The filter chamber is located at one end of the inner cylinder near the feed pipe. The filter chamber is inserted into the inner cylinder. The filter chamber includes a filter screen, a liquid-dispensing plate, a filter housing, and a sealing end cap. The outer cylinder has a first liquid outlet chamber and a second liquid outlet chamber at one end near the filter chamber. The filter screen protrudes from the outer side of the inner cylinder and communicates with the first liquid outlet chamber.

[0007] Preferably, the outer cylinder near the filter chamber is rotatably connected to the inner cylinder through two sealed bearings. The two sealed bearings form two sealing surfaces, and the two sealing surfaces, together with the outer surface of the outer cylinder and the inner surface of the inner cylinder, constitute the first liquid outlet chamber.

[0008] Preferably, the inner cylinder has multiple No. 1 liquid outlets on its surface near the No. 1 liquid outlet chamber, and the outer cylinder has a No. 2 liquid outlet on its inner end face near the No. 2 liquid outlet chamber, with the No. 2 liquid outlets fitting against the inner surface of the outer cylinder.

[0009] Preferably, the liquid-dispensing plate is located at the open end of the filter chamber, the open end of the filter chamber is inserted into the outer cylinder, and the open end of the filter chamber is directly opposite the first liquid outlet.

[0010] Preferably, the sealing end cap is fixedly connected to the end of the filter housing, and the sealing end cap is in contact with the end face of the outer cylinder.

[0011] Preferably, the sealing end cap is a rubber gasket, and a sealing mounting plate is sleeved on the outer side of the feed pipe. The sealing mounting plate is fixedly connected to the end face of the outer cylinder, and the sealing mounting plate is used to press the sealing end cap.

[0012] Preferably, one end of the liquid-dispensing plate that extends into the filter housing is fixedly connected to the filter housing, while the opposite sides of the liquid-dispensing plate are not connected to the filter housing.

[0013] Preferably, the liquid-dispensing plate is arc-shaped, and the bending direction of the liquid-dispensing plate is towards the rotation direction of the inner cylinder.

[0014] Compared with the prior art, this utility model provides an oil sludge high-dryness separation device with scum filtration function, which has the following beneficial effects: 1. Through the filter chamber and the No. 1 liquid outlet chamber, the scum located inside the oil after centrifugal separation can be filtered in a targeted manner, intercepting the scum to prevent it from being discharged with the oil, improving the purity of the separated oil, eliminating the need for an additional scum removal process for secondary oil treatment, and also preventing the scum from accumulating inside the equipment for a long time and clogging the oil outlet, thus avoiding a decrease in the equipment's separation efficiency.

[0015] 2. With the sealing mounting plate, when it is necessary to install or remove the filter chamber, simply remove the sealing mounting plate and back along the feed pipe. When the distance between the sealing mounting plate and the end face of the inner cylinder is greater than the length of the filter chamber, the filter chamber can be removed or installed. The whole operation process is simple, which facilitates the cleaning, maintenance or replacement of the filter chamber in the later stage, avoids long-term downtime of the equipment due to complicated filter chamber maintenance operations, and reduces equipment maintenance costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1 - Figure 7 This embodiment of an oil sludge high-dry separation device with scum filtration function includes an outer cylinder 1, an inner cylinder 2, a feed pipe 3, and a filter chamber 4. The feed pipe 3 is inserted into the inner cylinder 2, and one end of the feed pipe 3 inserted into the inner cylinder 2 is rotatably connected to the inner cylinder 2. The outer cylinder 1 is sleeved on the outside of the inner cylinder 2, and the outer cylinder 1 is rotatably connected to the inner cylinder 2. The outer cylinder 1 and the feed pipe 3 are fixedly connected by a fixing frame 5. To achieve the scum filtration function, the filter chamber 4 is located at the end of the inner cylinder 2 near the feed pipe 3. The filter chamber 4 is inserted into the inner cylinder 2. The filter chamber 4 includes a filter screen 401, a liquid-dispersing plate 402, a filter housing 403, and a sealing end cap 404. The filter housing 403 is used to connect the filter screen 401, the liquid-dispersing plate 402, and the sealing end cap 404. The filter screen 401 is used to directly intercept scum, the liquid-dispersing plate 402 assists the flow of oil, and the sealing end cap 404 is used for sealing the end face. Please see Figure 3 as well as Figure 5 The outer cylinder 1 has a first outlet chamber 6 and a second outlet chamber 7 at one end near the filter chamber 4. The filter screen 401 protrudes from the outer side of the inner cylinder 2 and communicates with the first outlet chamber 6, so that the filtered oil directly enters the first outlet chamber 6 for collection and is then discharged through a pipe. At the same time, the outer cylinder 1 is rotatably connected to the inner cylinder 2 through two sealed bearings 8. The two sealed bearings 8 form two sealing surfaces. The two sealing surfaces, together with the outer side of the outer cylinder 1 and the inner side of the inner cylinder 2, form the first outlet chamber 6. The sealed bearings 8 enable the outer cylinder 1 and the inner cylinder 2 to rotate and cooperate, and also prevent the oil in the first outlet chamber 6 from leaking.

[0020] Please see Figure 3 - Figure 5To guide the flow of different liquids, the inner cylinder 2 has multiple No. 1 liquid outlets 9 on its surface near the No. 1 liquid outlet 6, and the outer cylinder 1 has a No. 2 liquid outlet 10 on its inner end face near the No. 2 liquid outlet 7. The No. 2 liquid outlet 10 is attached to the inner surface of the outer cylinder 1. The No. 1 liquid outlet 9 is used to discharge the mixture of oil and scum, while the No. 2 liquid outlet 10 is adapted to the heavier water on the outside after centrifugation. The water flows into the No. 2 liquid outlet 7 along the inner surface of the outer cylinder 1. In addition, the liquid-dispensing plate 402 is located at the opening end of the filter chamber 4. The opening end of the filter chamber 4 is inserted into the outer cylinder 1, and the opening end of the filter chamber 4 is directly opposite the No. 1 liquid outlet 9. The mixture discharged from the No. 1 liquid outlet 9 can accurately enter the filter chamber 4. When the equipment is running, the inner cylinder 2 is driven to rotate by the motor. After the material enters the inner cylinder 2 through the feed pipe 3, it enters the space between the inner cylinder 2 and the outer cylinder 1 through the hole on the outer side of the inner cylinder 2. Under the action of centrifugal force, the heavier solid material on the outermost side is concentrated and discharged towards the conical end. The water on the outer side of the liquid material enters the second liquid outlet 7 through the second liquid outlet 10. The mixture of oil and scum on the inner side flows to the filter chamber 4 through the first liquid outlet 9. After the mixture enters the filter chamber 4, the filter screen 401 intercepts the scum. The oil passes through the filter screen 401 and enters the first liquid outlet 6, thus achieving the separation of scum and oil. This method specifically filters the scum on the inner side of the oil and improves the purity of the oil.

[0021] Please see Figure 1 - Figure 5 Furthermore, to improve oil filtration efficiency and equipment maintenance convenience, one end of the liquid-dispensing plate 402 extending into the filter housing 403 is fixedly connected to the filter housing 403, while the opposite sides of the liquid-dispensing plate 402 are not connected to the filter housing 403. The liquid-dispensing plate 402 is made of elastic material and is located inside the filter housing 403 when no external force is applied. The liquid-dispensing plate 402 is arc-shaped, with its bending direction facing the rotation direction of the inner cylinder 2. When the inner cylinder 2 rotates at high speed... The liquid-dispensing plate 402 is thrown out of the filter chamber 4 due to its own elasticity. The arc-shaped structure accelerates the flow of the inner oil into the filter chamber 4, further improving the separation efficiency. The sealing end cap 404 is fixedly connected to the end of the filter housing 403. The sealing end cap 404 is in contact with the end face of the outer cylinder 1, and the sealing end cap 404 is a rubber gasket. The outer side of the feed pipe 3 is fitted with a sealing mounting plate 11, which is fixedly connected to the end face of the outer cylinder 1. The sealing mounting plate 11 is used to squeeze the sealing end cap 404.

[0022] Under the pressure of the sealing mounting plate 11, the rubber sealing end cap 404 can tightly fit the end face of the outer cylinder 1, enhancing the sealing of the filtration area and preventing liquid leakage. When the filter chamber 4 needs maintenance, the sealing mounting plate 11 is first removed and moved back along the feed pipe 3. When the distance between the sealing mounting plate 11 and the end face of the inner cylinder 2 is greater than the length of the filter chamber 4, the filter chamber 4 can be taken out for cleaning, maintenance or replacement. The whole process does not require disassembling the main body of the equipment, and the operation is simple and convenient, effectively reducing equipment downtime for maintenance and lowering maintenance costs. The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
