DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 10 In an embodiment of the present invention, a waste oil impurity removal device includes a shell 1, a feeding port 3 is provided on the top of the shell 1, a bottom plate 7 is fixedly provided in the shell 1, a stirring rod 5 is rotatably provided above the bottom plate 7 in the shell 1, a collecting bin 6 is provided below the bottom plate 7 in the shell 1, a partition 11 is provided between one end of the bottom plate 7 and the inner wall of the shell 1, and both ends of the partition 11 are slidably fitted with the inner wall of the shell 1.

[0031] Preferably, since the partition 11 needs to rotate, there is a gap between the partition 11 and the end of the bottom plate 7, and between the side of the partition 11 away from the bottom plate 7 and the inner wall of the shell 1, so the second sealing plate 13 is elastically connected to the side walls of the partition 11 on both sides by springs, and the bottom plate 7 and the side walls of the shell 1 close to the second sealing plate 13 are both provided with square grooves 24 that are slidably adapted to the second sealing plate 13, and the square grooves 24 are elastically connected with the first sealing plate 12 that is slidably adapted to the second sealing plate 13 by springs. When in use, the second sealing plate 13 protrudes from the side walls of the partition 11 on both sides, and extends into the square grooves 24 to fit with the first sealing plate 12, thereby blocking the gap between the partition 11 and the bottom plate 7 and the shell 1. A driving assembly is provided at the center of the partition 11, and an auxiliary assembly is provided on the bottom plate 7. When the driving assembly rotates, the driving assembly causes the second sealing plate 13 to move into the partition 11. When the second sealing plate 13 moves into the partition 11 and cannot move, the driving assembly drives the partition 11 to rotate.

[0032] Preferably, two groups of feeding ports 3 are provided at the top of the shell 1 and are provided on one side of the top of the shell 1. The top of the bottom plate 7 is inclinedly provided with a drainage surface, and the higher end of the top of the bottom plate 7 is fixed to the inner wall of the shell 1, and the impurity discharge port is between the lower end and the shell 1. The partition 11 is rotatably provided in the discharge port, and the two ends of the partition 11 away from the second sealing plate 13 are tightly slidably fitted with the inner wall of the shell 1, that is, the wide side of the partition 11 is tightly slidably fitted with the inner wall of the shell 1, and the top transmission of the stirring rod 5 is provided with a second motor, and the second motor is fixedly provided at the top center position of the shell 1. A cleaning plate 2 is provided on the lower end side wall of the shell 1, and the cleaning plate 2 is provided at one end of the collecting bin 6 close to the partition 11. The collecting bin 6 can collect impurities on the bottom plate 7, and the impurities in the collecting bin 6 can be cleaned by opening the cleaning plate 2. The partition 11 is rotatably connected to the shell 1 through a driving assembly.

[0033] During use, when the waste oil is subjected to the impurity removal process by the flocculation method, the waste oil to be removed and the flocculant are added into the outer shell 1 through the feeding port 3, and then the second motor is started. The second motor rotates and drives the stirring rod 5 to rotate through the output end. The stirring rod 5 rotates to stir the waste oil and flocculant in the outer shell 1 to make them fully mixed. Then, the floating impurities in the waste oil will settle and fall on the drainage surface of the bottom plate 7 under the action of the flocculant. In this process, the second sealing plate 13 extends into the square groove 24 near the end of the square groove 24 and slides and fits with the first sealing plate 12, so that the partition plate 11 blocks the gap between the bottom plate 7 and the outer shell 1, that is, the discharge port is blocked, thereby preventing the oil from entering the collection bin 6. After the flocculation of the waste oil is completed, that is, the flocculant is fully mixed with the impurities in the oil and the precipitation is completed, the waste oil is removed through the external extraction device. The oil after impurities are removed from the shell 1 is extracted (the extraction device is a pump body and a delivery pipe commonly used in the prior art for extracting oil, and the specific related structure and working principle will not be described in detail here). Then, the driving component is started. The driving component rotates clockwise to first move the second sealing plate 13 into the partition 11 and separate from the square groove 24. Then, when the second sealing plate 13 moves into the partition 11 until it cannot move, the driving component uses the second sealing plate 13 to rotate the partition 11 clockwise to open the discharge port. Then, when the partition 11 rotates 90°, the driving component drives the auxiliary component to move relative to the partition 11 on the bottom plate 7, thereby scraping impurities precipitated on the bottom plate 7 to the discharge port, thereby realizing rapid cleaning of the bottom plate 7, thereby saving the time required for impurities to flow on the bottom plate 7 by gravity, thereby improving production efficiency.

[0034] See also Figure 2-Figure 6Preferably, the driving assembly includes a driving shaft 17; the driving shaft 17 passes through the centers of both ends of the partition 11, and the two ends of the driving shaft 17 are rotatably connected to the side walls of the housing 1, a sleeve 19 is sleeved on the periphery of the driving shaft 17, and the sleeve 19 is rotatably arranged in the partition 11, and a pull rope 18 is fixedly arranged at the center of one end of the second sealing plate 13 close to the sleeve 19, and the end of the pull rope 18 away from the second sealing plate 13 is fixedly connected to the sleeve 19; the driving shaft 17 and the partition 11 are rotatably fitted, and the end of the pull rope 18 away from the second sealing plate 13 slides through The side wall of the partition 11 is fixed to the sleeve 19; one end of the driving shaft 17 is transmission connected to the first motor 4, the first motor 4 is fixedly installed on the side wall of the shell 1, and the output shaft of the first motor 4 can also rotate freely when not started. A baffle rod 14 is arranged under the partition 11, and both ends of the baffle rod 14 are fixedly connected to the shell 1. The baffle rod 14 is arranged when the partition 11 is rotated 90° clockwise from a horizontal state, that is, the partition 11 is in a vertical state and away from one side of the bottom plate 7, thereby limiting the rotation angle of the partition 11.

[0035] When in use, when the partition 11 is in a horizontal state and the discharge port is blocked, the second sealing plate 13 slides and fits with the first sealing plate 12, and the second sealing plate 13 extends into the square groove 24 to block the gap between the partition 11 and the bottom plate 7 and the outer shell 1 to prevent oil from leaking out of the gap. When it is necessary to discharge impurities on the bottom plate 7 in the outer shell 1, the first motor 4 is started to rotate forward, and the first motor 4 drives the driving shaft 17 to rotate clockwise through the output shaft. The clockwise rotation of the driving shaft 17 first drives the sleeve 19 to rotate clockwise, and the rotation of the sleeve 19 winds the pull rope 18. At this time, since the second sealing plate 13 is in the square groove 24 and both ends of the partition 11 The outer shell 1 is in a tight fit, that is, the friction between the partition 11 and the outer shell 1 is relatively large, so the pull rope 18 is rolled up, which will cause the second sealing plate 13 to move into the partition 11, so that the second sealing plate 13 is separated from the square groove 24. When the second sealing plate 13 moves to the maximum movement state and cannot move, the active shaft 17 continues to rotate and then drives the partition 11 to rotate clockwise through the pull rope 18 and the second sealing plate 13. After rotating 90° clockwise, the partition 11 contacts the baffle rod 14, and then the partition 11 stops rotating. At this time, the partition 11 is in a vertical state, that is, the discharge port is opened, so that the impurities on the bottom plate 7 can flow into the collection bin 6 through the discharge port.

[0036] See also Figure 6-Figure 8Preferably, cylinders 192 are fixedly provided on the inner walls of both ends of the sleeve 19, and multiple groups of cylinders 192 are arranged in an annular array along the central axis of the sleeve 19. An annular groove 171 is provided on the driving shaft 17 to slide with the cylinder 192. A communicating notch 25 is provided on one side of the annular groove 171 close to the end of the sleeve 19. Multiple groups of notches 25 are arranged in an annular array along the central axis of the driving shaft 17, and the number and size of the notches 25 are adapted to the cylinder 192. When in use, When the partition 11 is in a horizontal state, the cylinder 192 is in the notch 25. At this time, when the discharge outlet needs to be opened, the first motor 4 is started to rotate forward, so that the driving shaft 17 rotates clockwise. The rotation of the driving shaft 17 drives the sleeve 19 to rotate clockwise through the cooperation between the notch 25 and the cylinder 192. The rotation of the sleeve 19 winds the pull rope 18, so that the second sealing plate 13 moves into the partition 11, and then drives the partition 11 to rotate 90° clockwise to open the discharge outlet.

[0037] See also Figure 4-Figure 7 Preferably, a slide groove 26 is provided at the bottom of the partition 11, and the slide groove 26 is symmetrically arranged along the bottom center of the partition 11, and the slide groove 26 is arranged at the bottom of the partition 11 along its width direction, and a trigger plate 22 is slidably arranged in the slide groove 26, and fixed plates 20 are provided on both sides of the outer periphery of the sleeve 19, and the bottom of the fixed plate 20 slides through the side wall of the partition 11, and the bottom of the fixed plate 20 is fixedly connected to the top of the trigger plate 22, and a movable groove 201 is provided on the fixed plate 20, and the outer periphery of the end of the sleeve 19 is rotatably connected to the swivel 19 1, an extension column 27 extending into the movable groove 201 is fixedly provided on the periphery of the rotating ring 191, and the two ends of the slide groove 26 are respectively facing the bottom plate 7 and the side of the shell 1 close to the cleaning plate 2, and the end of the trigger plate 22 close to the bottom plate 7 protrudes from the side wall of the partition 11 and slides with the bottom of the bottom plate 7. The end of the trigger plate 22 away from the bottom plate 7 is in the slide groove 26 and does not affect the opening and closing of the discharge port by the rotation of the partition 11. The movable groove 201 is inclined, and the inclination direction of the movable grooves 201 on the multiple groups of fixed plates 20 is consistent.

[0038] See also Fig. 9Preferably, positioning holes 202 are provided on the side walls of both sides of the fixing plate 20, and a plurality of positioning holes 202 are arranged in a vertical array on the side walls of the fixing plate 20. The inner wall of the partition 11 is elastically connected with a positioning post 203 slidably adapted to the positioning holes 202 through a spring, and the end of the positioning post 203 is a semicircular structure, and the inner wall of the positioning hole 202 is an arc structure adapted to the end of the positioning post 203. In this way, after the fixing plate 20 moves, there will be corresponding positioning holes 202 that are slidably adapted to the positioning post 203, and when the fixing plate 20 is subjected to a large external force, the positioning post 203 will move and shrink into the partition 11, that is, when the fixing plate 20 moves relative to the sleeve 19, the positioning post 203 will slide and separate from the adapted group of positioning holes 202, and slide and adapt to the next group of positioning holes 202. Through the setting of the positioning holes 202 and the positioning post 203, the positioning of the fixing plate 20 is realized, and the problem of easy movement of the fixing plate 20 is avoided.

[0039] When in use, in the initial state, that is, the partition 11 is in a horizontal state, the second sealing plate 13 is in the square groove 24, the cylinder 192 is in the notch 25, the trigger plate 22 is at the bottom of the partition 11, that is, the top of the trigger plate 22 is close to the bottom of the partition 11, the swivel 191 is at the top position in the movable groove 201, and the end of the trigger plate 22 protruding from the side wall of the partition 11 is slidably fitted with the bottom of the bottom plate 7, and the positioning column 203 is now adapted to a group of positioning holes 202; when the driving shaft 17 rotates clockwise, through the cooperation of the notch 25, the cylinder 192, the sleeve 19, and the pull rope 18, The second sealing plate 13 moves into the partition 11, and then the partition 11 rotates 90° clockwise. Under the action of the blocking rod 14, the trigger plate 22 first moves into the slide groove 26. The movement of the trigger plate 22 into the slide groove 26 will cause the fixed plate 20 to move toward the sleeve 19, and then through the cooperation of the movable groove 201 and the rotating ring 191, the sleeve 19 moves on the active shaft 17 away from the notch 25, and then the cylinder 192 moves into the annular groove 171, and then the driving component can drive the auxiliary component to move on the bottom plate 7 relative to the partition 11 to complete the scraping work of the bottom plate 7.

[0040] See also Figure 2-Figure 3 , Figure 7-Figure 9Preferably, the driving shaft 17 is elastically connected with a one-way block 172 through a spring, and the one-way block 172 is arranged at a position corresponding to the annular groove 171, and a plurality of one-way blocks 172 are arranged in an array along the central axis of the driving shaft 17. Preferably, the number of the one-way blocks 172 corresponds to the notch 25, and one end of the one-way block 172 extending into the annular groove 171 is provided with an inclined surface. When in use, when the cylinder 192 is in the annular groove 171, the driving shaft 17 rotates clockwise, driving the one-way block 172 to rotate clockwise. At this time, when the one-way block 172 contacts the cylinder 192 through the inclined surface, the one-way block 172 will slide and shrink toward the inside of the driving shaft 17, that is, when the driving shaft 17 rotates clockwise, the one-way block 172 will not conflict with the cylinder 192, and when the driving shaft 17 rotates counterclockwise, the one-way block 172 rotates counterclockwise. At this time, the one-way block 172 will contact the cylinder 192 through the inclined surface. 192 collides, and the side where the one-way block 172 collides with the cylinder 192 is flush with the side of the notch 25, so as to facilitate the subsequent movement and reset of the cylinder 192 toward the notch 25. Then, the active shaft 17 drives the sleeve 19 to rotate counterclockwise through the collision between the one-way block 172 and the cylinder 192, thereby causing the partition 11 to rotate counterclockwise and reset. The rotation and reset of the partition 11 will cause the trigger plate 22 to cooperate with the bottom side wall of the bottom plate 7, and cause the trigger plate 22 to move and reset. After the trigger plate 22 moves and resets, a restriction on the rotation and reset of the partition 11 is formed, and the movement and reset of the trigger plate 22 will also cause the cylinder 192 to move and reset into the notch 25 through the cooperation of the fixed plate 20, the movable groove 201, and the extension column 27. Then, the second sealing plate 13 elastically moves and resets to extend into the square groove 24 and cooperate with the first sealing plate 12 to form a blockage for the discharge port.

[0041] See also Figure 6-Figure 7Preferably, the top two ends of the trigger plate 22 are symmetrically slidably connected to the limit plate 21 along the center, and a spring is arranged between the limit plate 21 and the inner wall of the trigger plate 22, and an air bag 23 is arranged between the side of the limit plate 21 away from the fixed plate 20 and the inner wall of the trigger plate 22, and the two side wall arrays of the trigger plate 22 are provided with a plurality of groups of air holes 210 connected with the air bag 23. When the trigger plate 22 cooperates with the bottom plate 7, the top height of the limit plate 21 is lower than the bottom height of the second sealing plate 13, so that it will not affect the movement of the second sealing plate 13 in the partition 11, and when the trigger plate 22 moves into the slide groove 26, the limit plate 21 extends into the partition 11 to limit the position of the second sealing plate 13. When in use, after the partition 11 rotates 90° clockwise, the trigger plate 22 moves into the slide groove 26 under the action of the blocking rod 14, so that the limit plate 21 moves and extends into the partition 11. At this time, the second sealing plate 13 is in a position close to the sleeve 19, and the second sealing plate The end of 13 away from the sleeve 19 is on the side of the limit plate 21 close to the sleeve 19, and the movement of the trigger plate 22 into the slide groove 26 will cause the cylinder 192 to move into the annular groove 171, so the second sealing plate 13 will move and reset under the action of elasticity. At this time, the second sealing plate 13 will push the limit plate 21 to move. The movement of the limit plate 21 will cause its corresponding spring to stretch and compress the airbag 23. The compression of the airbag 23 causes the gas to be ejected through the air hole 210, thereby cleaning the end of the second sealing plate 13 to prevent impurities from adhering thereto, thereby affecting the subsequent sealing state and extending its service life. By arranging the first sealing plate 12 in the square groove 24, impurities will not accumulate in the square groove 24. When the second sealing plate 13 is separated from the square groove 24, the first sealing plate 12 will move toward the opening of the square groove 24 under the action of the corresponding spring to prevent impurities from flowing into the square groove 24 and affecting the subsequent sealing effect.

[0042] See also Figure 2-Figure 3 , Figure 10-11Preferably, the auxiliary component includes a scraper 8; a circular frame 802 is sleeved on the periphery of the scraper 8, and connecting columns 803 are fixedly arranged at both ends of the circular frame 802, and the end of the connecting column 803 away from the circular frame 802 is rotatably connected to the conveyor belt 10, and the two ends of the conveyor belt 10 are transmission-matched with auxiliary shafts 101, and the inner wall of the shell 1 is provided with a groove 28, and the conveyor belt 10 and the auxiliary shaft 101 are both arranged in the groove 28, and the groove 28 and the drainage surface are arranged in a parallel state, and horizontal plates are arranged on both sides of the scraper 8, Springs are provided on the top of the transverse plate and the circular frame 802, and the bottom of the scraper 8 slides in contact with the top of the bottom plate 7. When in use, when the auxiliary shaft 101 rotates clockwise, the conveyor belt 10 rotates clockwise, and then the connecting column 803 rotates clockwise. The rotation of the connecting column 803 drives the circular frame 802 to move toward the partition 11 on the bottom plate 7. During this process, the scraper 8 scrapes off the impurities on the bottom plate 7, so that the impurities on the bottom plate 7 are quickly transported to the collection bin 6, thereby improving efficiency.

[0043] Furthermore, preferably, a guide rod 801 is fixedly provided on the top of the scraper 8, and guide grooves 9 are provided on both sides of the inner wall of the shell 1, which are slidably fitted with the guide rod 801. The guide grooves 9 and the drainage surface are arranged in a parallel state. The end of the guide groove 9 close to the partition 11 is a lifting part, corresponding to the end of the conveyor belt 10 close to the partition 11, and the end of the guide groove 9 away from the partition 11 is a descending part, corresponding to the end of the conveyor belt 10 away from the partition 11. When in use, when the scraper 8 moves, the guide rod 801 slides in the guide groove 9, and when the connecting column 803 moves close to the partition 11 and then moves to the top of the groove 28, the guide rod 801 moves to the end of the guide groove 9, and then moves to the side of the guide groove 9 away from the groove 28. At this time, the conveyor belt 10 continues to move, so that the connecting column 803 moves to the end of the guide groove 9, and then moves to the side of the guide groove 9 away from the groove 28. The column 803 moves back in the direction away from the partition 11, and then the guide rod 801 moves upward a certain distance through the lifting part of the guide groove 9. The movement of the guide rod 801 causes the scraper 8 to move upward and separate from the top of the bottom plate 7. Subsequently, when the connecting column 803 and the guide rod 801 move to the end of the conveyor belt 10 away from the partition 11 and the descending part of the guide groove 9 respectively, the scraper 8 is again fitted with the top of the bottom plate 7 under the action of the spring corresponding to the cross plate, thereby facilitating the cleaning of the top of the bottom plate 7 again. In the process of the scraper 8 moving back away from the partition 11, the scraper 8 moves upward to form a gap with the bottom plate 7, thereby avoiding the problem that the scraper 8 remains in contact with the bottom plate 7 on the way back, causing impurities to not be cleaned.

[0044] Furthermore, preferably, a driven shaft 15 is rotatably connected in the baffle rod 14, a tooth plate 16 is slidably connected to the center of the side wall of the baffle rod 14, a first magnet is provided at one end of the tooth plate 16 close to the bottom plate 7, a second magnet adapted to the first magnet is embedded in the bottom side wall of the partition 11, and the magnetic poles of the first magnet and the second magnet are opposite at one end, the tooth plate 16 is arranged above the driven shaft 15, and a tooth groove meshing with the tooth plate 16 is arranged on the periphery of the driven shaft 15, and a first tooth ring 29 is fixedly arranged on a group of auxiliary shafts 101 close to the partition 11, and the first tooth ring 29 is fixedly arranged on the auxiliary shaft 10 1 is away from the scraper 8, and the outer periphery of the driving shaft 17 away from the partition 11 is fixedly provided with a second gear ring 30. The outer periphery of the end of the driven shaft 15 away from the partition 11 is rotatably connected with an L plate 151. The two ends of the driven shaft 15 are provided with threads. The inner side wall of the L plate 151 is provided with screw teeth adapted to the threads on the driven shaft 15. The end of the L plate 151 away from the driven shaft 15 is rotatably connected with a gear 152. The gear 152 is in transmission cooperation with the first gear ring 29 and the second gear ring 30. The L plate 151, the gear 152, the first gear ring 29, and the second gear ring 30 are all arranged in the side wall of the housing 1.

[0045] During specific use, when the partition 11 rotates clockwise, the partition 11 pushes the tooth plate 16 to move away from the bottom plate 7, thereby causing the driven shaft 15 to rotate counterclockwise. The rotation of the driven shaft 15 causes the L plate 151 to move toward the direction of the partition 11, thereby causing the gear 152 to move toward the direction of the partition 11, thereby achieving a state of adaptation with the first gear ring 29 and the second gear ring 30. At this time, the driving shaft 17 rotates through the second gear ring 30, the gear 152, and the first gear ring 29 to drive the auxiliary shaft 101 to rotate clockwise; when the partition 11 rotates counterclockwise, the tooth plate 16 is driven to move and reset through the adsorption action of the first magnet and the second magnet. At this time, the tooth plate 16 drives the driven shaft 15 to move clockwise, causing the L plate 151 to move and reset, thereby causing the gear 152 to separate from the first gear ring 29 and the second gear ring 30, thereby causing the auxiliary shaft 101 to no longer rotate.

After the impurities on the bottom plate 7 are cleaned, the driving assembly is started to rotate and reset the partition 11. The partition 11 rotates and resets to allow the second sealing plate 13 to move into the square groove 24 and reset, and then the next batch of waste oil impurity removal work is carried out.
