Description

Technical Field

[0001] This utility model relates to the field of oil extraction equipment technology, specifically a bottom-discharge centrifugal oil extractor. Background Technology

[0002] Bottom-discharge centrifugal oil separators are devices that use centrifugal force to separate oil from solids in materials. The discharge port is located at the bottom of the equipment, and the material is discharged through the bottom after oil removal. This equipment is widely used in food processing, machinery manufacturing, and other fields, and features high efficiency, energy saving, and a high degree of automation.

[0003] In existing centrifugal oil separators, the high-speed rotation of the driven drum generates strong centrifugal force, causing oil in the material to be thrown out. During this process, the thrown-out oil remains attached to the inner wall of the drum, making it impossible to collect. Over time, this accumulation is difficult to remove, resulting in waste and requiring frequent shutdowns for cleaning, increasing maintenance time and costs. Furthermore, as the core component of the oil separator, the drum can become clogged with oil in the filter pores of its inner wall over time, forming stubborn grease and reducing oil removal efficiency. Regular disassembly and cleaning are necessary, and the oil can be thoroughly removed through chemical cleaning or high-pressure flushing to restore the equipment's performance. Typically, the drum is fixed to the drive system with multiple bolts. Disassembly requires workers to use tools to unscrew the bolts one by one, and then reinstall them after cleaning. This cumbersome process consumes a lot of time and reduces the ease of maintenance for the oil separator. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-5As shown, a bottom-discharge centrifugal oil separator includes a cylinder 1 with an oil discharge pipe at its bottom for discharging oil to the outside. A lifting assembly 2, consisting of a lead screw and a guide block, is installed at the top of the cylinder 1. When the lead screw rotates, it drives a fixed frame 3 threadedly connected to it to move up and down. Simultaneously, the fixed frame 3 slides along the outer side of the guide block, which restricts the movement path of the fixed frame 3. A fixed frame 3 is installed on the outer side of the lifting assembly 2. A power assembly 4 and a discharge assembly 7 are installed on the top of the fixed frame 3. The power assembly 4 consists of a motor and two bevel gears, one of which is fixed to... On the outside of the transmission rod 5, a bevel gear is used to transmit the kinetic energy output by the motor and drive the transmission rod 5 to rotate; the transmission rod 5 is provided on the outside of the power assembly 4, and a drum 6 is provided on the inside of the cylinder 1. The bottom of the drum 6 is tapered and has a discharge port; a discharge pipe 11 is provided at the bottom of the drum 6, which is fixed to the bottom of the cylinder 1 and located below the discharge port of the drum 6. It is inclined and used to discharge waste material into the cylinder 1. A connecting frame 8 is fixed on the outside of the transmission rod 5. Four connecting blocks 9 are slidably connected on the inside of the connecting frame 8, and four sets of outer shells 10 are fixedly connected on the outside of the connecting frame 8.

[0027] The drive assembly 12 is disposed on the inner wall of the cylinder 1. A scraper ring 13 is disposed on the outer side of the drive assembly 12. The bottom of the scraper ring 13 is flat and can scrape off the oil on the inner wall of the cylinder 1 when it moves downward. A guide assembly 14 is disposed on the outer side of the scraper ring 13.

[0028] An adjustment component 15 is located inside the housing 10. An adjustment block 16 with an arc-shaped surface is provided on the outside of the adjustment component 15. A guide component 17 is provided on the outside of the adjustment block 16. A connecting seat 18 is located on the outside of the guide component 17. A second spring 19 is sleeved on the outside of the connecting seat 18. Two sets of fixing components 20 are provided on the outside of the connecting seat 18. A limit block 21 is rotatably connected to the outside of the housing 10.

[0029] The discharge assembly 7 includes a cylinder 71 fixed to the top of the fixed frame 3. The piston rod of the cylinder 71 is fixedly connected to an extension rod 72. One end of the extension rod 72 is fixedly connected to a blocking block 73, which is slidably connected to the discharge port of the drum 6. The outer side of the extension rod 72 is slidably connected to the inner wall of the transmission rod 5. After the degreasing is completed, the piston rod of the cylinder 71 retracts, and the blocking block 73 is moved upward through the extension rod 72, so that the bottom of the drum 6 is unblocked. Under the action of gravity, the waste material rolls down along the conical slope at the bottom of the drum 6 into the discharge pipe 11, thus completing the discharge.

[0030] The drive assembly 12 includes a motor 121 fixed to the top of the cylinder 1. A screw 122 is provided at the output end of the motor 121. Two sets of rollers 123 are fixedly connected to the outer side of the scraper ring 13. A guide rail is provided on the inner wall of the cylinder 1. The rollers 123 are slidably connected to the inner side of the guide rail. The outer side of the screw 122 is threadedly connected to the inner wall of the scraper ring 13. The motor 121 drives the screw 122 to rotate, which causes the scraper ring 13 to move vertically along the axial direction of the screw 122 and slide along the inner wall of the cylinder 1 through the rollers 123.

[0031] The flow guiding assembly 14 includes an oil scraping groove 141 opened on the outside of the scraper ring 13. The inner wall of the scraper ring 13 is provided with a plurality of flow guiding holes 142. The oil scraping groove 141 is connected to the inner side of the flow guiding holes 142. The oil scraped by the oil scraping groove 141 will gradually flow into the flow guiding holes 142 and fall into the bottom of the cylinder 1.

[0032] The adjustment assembly 15 includes a slider 151 that slides inside the housing 10. A slider 152 and an adjustment block 16 are fixedly connected to the outside of the slider 151. A first spring 153 is sleeved on the outside of the slider 152. The outside of the slider 152 is slidably connected to the inner wall of the housing 10. When the slider 151 slides, it will compress the first spring 153. The elastic force generated by the first spring 153 will push the slider 151 to reset. The slider 152 is used to limit the compression path of the first spring 153 and improve its stability.

[0033] The guide assembly 17 includes a limiting groove 171 formed on the outside of the adjusting block 16. A pulley 172 is slidably connected to the inner wall of the limiting groove 171. The outer side of the pulley 172 is fixedly connected to one side of the connecting seat 18. When the adjusting block 16 moves, the pulley 172 can slide along the inner side of the limiting groove 171. The position of the pulley 172 will not change and will remain in the original position with the connecting seat 18 without lateral movement.

[0034] The fixing component 20 includes a positioning rod 201 fixed to the outside of the connecting seat 18. A fixing groove 202 is provided on the inner side of the connecting block 9. The outer side of the positioning rod 201 is slidably connected to the inner wall of the fixing groove 202. When the positioning rod 201 enters the inner side of the fixing groove 202, it can fix the connecting block 9 and the connecting frame 8.

[0035] Working principle: During use, when cleaning the inner wall of the cylinder 1, the motor 121 first drives the screw 122 to rotate, causing the scraper ring 13 to move up and down along the inner wall of the cylinder 1. The roller 123 restricts the movement path of the scraper ring 13 to keep it stable. When the scraper ring 13 moves upward, the oil scraping groove 141 scrapes off the oil residue on the inner wall of the cylinder 1, causing it to adhere to the surface of the oil scraping groove 141. As the amount of oil accumulates, the oil is squeezed under the action of gravity and gradually flows into the guide hole 142 and falls into the cylinder. 1. The oil is discharged from the bottom of the cylinder 1 through the drain pipe, completing the cleaning. When the drum 6 needs to be replaced, first rotate the lead screw in the lifting assembly 2 to drive the fixed bracket 3, which is threaded to its outer side, to move upward and drive the drum 6 to disengage from the inner side of the cylinder 1. After reaching a certain height, slide the slider 151 to drive the adjusting block 16 to move. Under the push of the second spring 19, the pulley 172 slides along the limit groove 171 on the surface of the adjusting block 16. When the pulley 172 slides into the adjusting block 16 with the connecting seat 18, the adjustment block 16 is fully extended. When the lowest point of the surface of segment 16 is reached, the positioning rod 201 moves along with it, and one end of it disengages from the inside of the fixing groove 202, causing the connecting block 9 to lose its limit and disengage from the fixed connection with the connecting frame 8. Then, the limiting block 21 is rotated downwards so that it is on the side of the sliding button 151, preventing the sliding button 151 from resetting under the action of the first spring 153. Then, following this step, the other three sets of connecting blocks 9 are disengaged from their limits. Then, the drum 6 is pulled out downwards to complete the disassembly. When installing the drum 6, the connecting blocks 9 on its inner wall are aligned and inserted into the inside of the connecting frame 8 to form a preliminary connection. Then, the limiting block 21 is rotated upwards, and the sliding button 151 loses its limit and resets under the push of the first spring 153. The adjusting block 16 moves along with it and changes its position so that the pulley 172 is at its highest point on the outside. The positioning rod 201 is then pushed into the inside of the fixing groove 202, making the connecting block 9 fixed to the connecting frame 8. Then, the other three sets of connecting blocks 9 are fixed in sequence to complete the installation.
