Description

Technical Field

[0001] The utility model relates to the technical field of oil residue separation devices, and specifically relates to an oil residue separation device for oil extraction. Background Technique

[0002] In the prior art, centrifugal separation is often used for separating petroleum and oil residue. That is to say, the strong centrifugal force generated by a high-speed rotating drum is used to separate the residue and oil in a solid-liquid manner to achieve the purpose of oil product filtration.

[0003] In the prior art, such as an oil residue separation device for oil extraction according to the Chinese patent with the application number 202322007960.8, when in use, a scraper 304 can be used to assist in removing the oil residue on the surface of the filter screen. However, scraping the filter screen up and down with the scraper 304 makes it easier for the oil residue to embed into the mesh holes of the filter screen, and its cleaning effect is poor. Therefore, an oil residue separation device for oil extraction is needed to improve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide an oil residue separation device for oil extraction to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An oil residue separation device for oil extraction, including a housing, a fixed frame is fixedly arranged inside the housing, a transmission rod is movably arranged in the middle of the inner side of the fixed frame through a bearing, a rotating drum is fixedly arranged at the lower end of the transmission rod, a filter screen is fixedly arranged on the outer surface of the rotating drum, a cleaning mechanism for cleaning the filter screen is arranged outside the filter screen inside the fixed frame, the cleaning mechanism includes a fixed ring, a wire cleaning brush, a screw rod, and a sliding rod. The upper end of the outer surface of the rotating drum is movably sleeved with a fixed ring, a number of wire cleaning brushes are evenly fixedly arranged on the inner side wall of the fixed ring, a screw rod is movably arranged through a bearing on one side inside the fixed frame, a sliding rod is fixedly arranged on the side inside the fixed frame away from the screw rod, the side of the fixed ring close to the screw rod is movably sleeved on the outer surface of the screw rod through a thread, and the side of the fixed ring close to the sliding rod is movably sleeved on the outer surface of the sliding rod.

[0006] Preferably, a support roller is movably arranged through a rotating shaft at the lower end inside the fixed frame, and the support roller is movably clamped at the lower end of the rotating drum. The stability of the rotating drum can be improved through the support roller.

[0007] Preferably, a number of feed ports are evenly opened at the upper end of the rotating drum. Through the feed ports, it is convenient to rotate and input the oil residue that needs to be centrifuged into the rotating drum.

[0008] Preferably, an annular groove is fixedly arranged on the outer surface of the upper end of the rotary drum. When there is no need to clean the filter screen, the fixed ring and the wire cleaning brush are at the upper end of the rotary drum. At this time, the wire cleaning is flush with the annular groove. In this way, when the rotary drum rotates, the wire cleaning will not contact the filter screen and the rotary drum, thus avoiding unnecessary frictional losses.

[0009] Preferably, an electric push rod is arranged at the lower end of the fixed frame. The movable end of the electric push rod is movably arranged with a sealing bottom plate through a bearing. The sealing bottom plate is movably clamped inside the rotary drum, and the sealing bottom plate can play a role in sealing the lower end of the rotary drum. At the same time, when the rotary drum rotates, the sealing bottom plate is interference-fitted inside the lower end of the rotary drum. At the same time, since the movable end of the electric push rod is connected to the sealing bottom plate through a bearing, the rotary drum can drive the sealing bottom plate to rotate together. When discharging slag is required, the electric push rod contracts to drive the sealing bottom plate to move downwards, as Figure 3 shown, and at this time, the impurities at the lower end inside the rotary drum can be discharged.

[0010] Preferably, a protrusion is arranged at the upper end of the sealing bottom plate, and a lower slope is formed through the protrusion. In this way, when the sealing bottom plate moves downwards and separates from the rotary drum, the impurities at the upper end of the sealing bottom plate are more likely to fall off.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] When the present utility model needs to clean the filter screen, the rotary drum is kept in a stopped state at this time. At this time, by contracting the electric push rod, the sealing bottom plate can be driven to move downwards, as Figure 3 shown, and at this time, the impurities at the lower end inside the rotary drum can be discharged. At this time, the fixed ring can be driven to move downwards by rotating the screw. When the fixed ring moves downwards, the wire cleaning brush moves downwards. At this time, the wire cleaning brush can clean the mesh holes of the filter screen. The wire cleaning brush can easily be inserted into the mesh holes of the filter screen from the outside, so that the impurities in the mesh holes of the filter screen are pushed into the rotary drum and discharged from the opened sealing bottom plate. In this way, compared with scraping and cleaning the filter screen from the inside, the present device cleans the filter screen from the outside of the filter screen and uses the wire cleaning brush to clean, making it easier to clean the mesh holes of the filter screen, and thus better cleaning the impurities stuck inside the filter screen.

[0013] When the present utility model discharges slag, the entire sealing bottom plate is separated from the rotary drum. The impurities remaining inside the rotary drum can fall off more easily under the action of gravity and are easier to clean. In this way, the impurities of the present device are better cleaned, more convenient, and faster. Description of the Drawings

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an oil residue separation device for oil extraction, including a housing 1, a fixing frame 2 is fixedly arranged inside the housing 1, a transmission rod 3 is movably arranged in the middle of the inner side of the fixing frame 2 through a bearing, a rotating drum 4 is fixedly arranged at the lower end of the transmission rod 3, a filter screen 5 is fixedly arranged on the outer surface of the rotating drum 4, a cleaning mechanism for cleaning the filter screen 5 is arranged outside the filter screen 5 inside the fixing frame 2, the cleaning mechanism includes a fixing ring 6, a wire cleaning brush 7, a screw 8, and a sliding rod 9, a fixing ring 6 is movably sleeved on the upper end of the outer surface of the rotating drum 4, a plurality of wire cleaning brushes 7 are uniformly fixedly arranged on the inner side wall of the fixing ring 6, a screw 8 is movably arranged through a bearing on one side inside the fixing frame 2, a sliding rod 9 is fixedly arranged on the side of the fixing frame 2 away from the screw 8, the side of the fixing ring 6 close to the screw 8 is movably sleeved on the outer surface of the screw 8 through a thread, and the side of the fixing ring 6 close to the sliding rod 9 is movably sleeved on the outer surface of the sliding rod 9.

[0021] A support roller 10 is movably arranged at the lower end inside the fixed frame 2 through a rotating shaft. The support roller 10 is movably engaged at the lower end of the rotating drum 4. The stability of the rotating drum 4 can be improved through the support roller 10.

[0022] A number of feeding ports 11 are evenly arranged at the upper end of the rotating drum 4. Through the feeding ports 11, it is convenient to rotate and input the oil residue that needs to be centrifuged into the rotating drum 4.

[0023] An annular groove 12 is fixedly arranged on the outer surface of the upper end of the rotating drum 4. When there is no need to clean the filter screen 5, the fixed ring 6 and the wire cleaning brush 7 are at the upper end of the rotating drum 4. At this time, the wire cleaning is flush with the annular groove 12. In this way, when the rotating drum 4 rotates, the wire cleaning will not contact the filter screen and the rotating drum 4, so unnecessary frictional losses can be avoided.

[0024] An electric push rod 13 is arranged at the lower end of the fixed frame 2. The movable end of the electric push rod 13 is movably arranged through a bearing with a sealing bottom plate 14. The sealing bottom plate 14 is movably engaged inside the rotating drum 4. The sealing bottom plate 14 can play a role in sealing the lower end of the rotating drum 4. At the same time, when the rotating drum 4 rotates, the sealing bottom plate 14 is press-fitted inside the lower end of the rotating drum 4. At the same time, since the movable end of the electric push rod 13 is connected to the sealing bottom plate 14 through a bearing, the rotating drum 4 can drive the sealing bottom plate 14 to rotate together by using friction. When discharging slag is required, the electric push rod 13 contracts to drive the sealing bottom plate 14 to move downward, as Figure 3 shown, and at this time, the impurities at the lower end inside the rotating drum 4 can be discharged.

[0025] A protrusion 15 is arranged at the upper end of the sealing bottom plate 14. A lower slope is formed through the protrusion 15. In this way, when the sealing bottom plate 14 moves downward and separates from the rotating drum 4, the impurities at the upper end of the sealing bottom plate 14 are more likely to fall off.

[0026] Working principle: When using this device, through the feeding port 11, it is convenient to rotate and input the oil residue that needs to be centrifuged into the rotating drum 4. Subsequently, the transmission rod 3 is externally connected to a motor. The motor can drive the rotating drum 4, the filter screen 5, and the sealing bottom plate 14 to rotate at a high speed, and the oil residue at the upper end of the sealing bottom plate 14 inside the rotating drum 4 rotates at a high speed. In this way, the oil residue separation operation can be carried out through centrifugal force. The oil liquid is thrown out and then impacts on the inner side wall of the housing 1 and finally flows down along the housing 1. The impurities will remain inside the rotating drum 4.

[0027] As the device is used, when the filter screen 5 needs to be cleaned, at this time, the rotating drum 4 is kept in a stopped state. At this time, the electric push rod 13 contracts, and the sealing bottom plate 14 can be driven to move downward, as Figure 3As shown, the impurities at the lower end inside the rotating drum 4 can be discharged at this time. At this time, the screw 8 can be rotated to drive the fixed ring 6 to move downward. When the fixed ring 6 moves downward, the wire cleaning brush 7 moves downward. At this time, the wire cleaning brush 7 can clean the mesh holes of the filter screen 5. The wire cleaning brush 7 can easily be inserted into the mesh holes of the filter screen 5 from the outside, so that the impurities in the mesh holes of the filter screen 5 are pushed into the rotating drum 4 and discharged from the opened sealing bottom plate 14. In this way, compared with scraping and cleaning the filter screen from the inside, this device cleans the filter screen from the outside of the filter screen and uses the wire cleaning brush 7 for cleaning, making it easier to clean the mesh holes of the filter screen 5, so that the impurities stuck inside the filter screen can be better cleaned.

[0028] Moreover, when the device discharges slag, the entire sealing bottom plate 14 is separated from the rotating drum 4. The impurities remaining inside the rotating drum 4 can more easily fall under the action of gravity and are easier to clean. In this way, the impurities of this device can be better cleaned, more conveniently and faster.
