Description

Technical Field

[0001] The present invention relates to the technical field of oil fume purification, and in particular to an oil fume purification method of a commercial oil fume purification all-in-one machine. Background Art

[0002] The oil fume purification machine is used to purify the large amount of oil fume generated in the process of food processing and cooking in large hotels, canteens and food processing plants, so as to avoid the oil fume being directly discharged into the atmosphere and causing air pollution.

[0003] In the prior art, when actually treating oil fume, harmful substances in the oil fume are usually first adsorbed and purified by water mist, and then the oil stains in the oil fume are filtered out by a filter. For example, the invention patent with application publication number CN109028240A discloses a commercial oil fume purification all-in-one machine, which adopts the above method.

[0004] However, after actual application by technicians in this field, it was found that the above method still has some disadvantages. The most obvious one is that as the grease on the surface of the filter increases, the operator often needs to manually remove and clean the filter, or use the manually driven scraper provided in the above invention patent to scrape and clean the filter. Both methods require manual cleaning on a regular basis, which is inconvenient and labor-intensive.

[0005] In addition, since the interval between two adjacent grease cleanings is long, the grease on the surface of the filter is prone to stubborn adhesion, which often makes it difficult to manually clean or scrape it, and the actual cleaning effect is not ideal.

[0006] Therefore, it is necessary to invent a commercial oil fume purification method of an all-in-one oil fume purification machine to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide an oil fume purification method for a commercial oil fume purification integrated machine, which is provided with an oil fume purification mechanism, a transmission drive mechanism, a secondary trigger mechanism and a one-way scraping mechanism, so as to utilize the oil fume purification mechanism to purify the oil fume. During the purification process, the transmission drive mechanism activated by the water flow drives the one-way scraping mechanism to descend, and the one-way scraping mechanism is cleaned during the descent process. Subsequently, the secondary trigger mechanism triggers the one-way scraping mechanism under the drive of the transmission drive mechanism, so that the one-way scraping mechanism no longer contacts the oil fume purification mechanism, and avoids unnecessary friction with the cleaned oil fume purification mechanism during the subsequent resetting process of the one-way scraping mechanism, so as to prolong the service life of the oil fume purification mechanism and the one-way scraping mechanism. During the subsequent resetting process of the one-way scraping mechanism driven by the transmission drive mechanism, the one-way scraping mechanism is driven to be cleaned. , the secondary trigger mechanism triggers the one-way scraping mechanism again, thereby restoring the one-way scraping mechanism, so that the oil fume purification mechanism can be cleaned again under the drive of the transmission drive mechanism, thereby shortening the time interval between two adjacent cleaning operations, in order to solve the problem raised in the above background technology that as the grease on the surface of the filter increases, the operator often needs to manually remove and clean the filter, or use the manual scraper provided in the above invention patent to scrape and clean the filter. Both methods require manual regular cleaning, which is inconvenient and labor-intensive. In addition, since the interval between two adjacent grease cleanings is long, the grease on the surface of the filter is prone to stubborn adhesion, and there are often great operational difficulties in subsequent manual cleaning or manual scraping, and the actual cleaning effect is not ideal.

[0013] Preferably, the secondary trigger mechanism comprises an outer sleeve plate, a longitudinal trigger column and a transverse trigger column; The outer sleeve plate is fixedly sleeved on the outer bottom end of the outer sleeve, the longitudinal trigger column is fixedly arranged on the end of the outer sleeve plate, the transverse trigger column is fixedly arranged on the inner wall of the second shell, and the bottom end of the longitudinal trigger column and the bottom of the transverse trigger column are both provided with inclined surfaces.

[0014] Preferably, the one-way scraping mechanism comprises an inverted U-shaped frame, a scraper, a guide groove, a moving rod, a trigger block, a second return spring, a first magnet and a second magnet; The inverted U-shaped frame is fixedly arranged at the bottom end of the inner sleeve, the scraper is slidably arranged on the inner side of the inverted U-shaped frame in a horizontal direction and its right end is in contact with the left side of the filter screen, the guide groove is opened on the inner side of the inverted U-shaped frame and extends to the top of the inverted U-shaped frame, the moving rod is slidably arranged on the inner side of the guide groove in a horizontal direction and is fixedly connected to the scraper, the trigger block is fixedly arranged on the top of the moving rod, the second return spring is fixedly connected between the inner wall of the guide groove and the side wall of the moving rod, the first magnet is fixedly arranged on the left side of the moving rod, and the second magnet is fixedly nested on the left side of the guide groove and is colinear with the first magnet in the horizontal direction.

[0015] Preferably, the method specifically comprises the following steps: S1. The suction fan inside the smoke inlet pipe inputs the oil smoke into the first shell through the smoke inlet pipe, and the oil smoke is continuously transmitted along the channel between two adjacent guide baffles. During this process, water flows into the sealing cover through the water supply pipe, and then enters the multiple atomizing nozzles through the water inlet main pipe and multiple water inlet branches, and finally forms water mist in multiple channels. The water mist preliminarily purifies the oil smoke when the oil smoke passes through. The preliminarily purified oil smoke passes through the filter screen for secondary purification, and then is input into the atmosphere under the action of the suction fan inside the smoke outlet pipe; S2. When water is inputted into the sealing cover from the water supply pipe, the water drives the impeller to rotate continuously. When the impeller rotates, the reciprocating screw is driven to rotate continuously. When the reciprocating screw rotates, the outer sleeve guided by the guide plate is driven to descend. When the outer sleeve descends, the inner sleeve is driven to descend through the first return spring, and the longitudinal trigger column is driven to descend through the outer sleeve plate; S3. When the inner casing descends, the inverted U-shaped frame drives the moving rod to descend, and when the moving rod descends, the scraper is driven to descend synchronously. During the descent of the scraper, the grease attached to the left wall of the filter screen is scraped off, and the grease is pushed at the same time, so that the grease falls and passes through the oil guide port into the oil-water separator for treatment; S4, when the outer sleeve descends to a first threshold, the bottom of the inverted U-shaped frame fits with the top of the baffle bar, and the filter screen is cleaned. At this time, due to the obstruction of the baffle bar, the inverted U-shaped frame cannot continue to descend. Subsequently, as the outer sleeve continues to descend, the first return spring is compressed by the inner sleeve that also cannot descend, and at the same time, the outer sleeve plate continues to drive the longitudinal trigger column to descend; S5, when the outer sleeve descends to a second threshold, the bottom of the longitudinal trigger column fits with the inclined surface on the right side of the top of the trigger block. As the longitudinal trigger column continues to descend, the longitudinal trigger column drives the moving rod to move leftward inside the guide groove through the trigger block. When the moving rod moves leftward, the second return spring is compressed, and the first magnet is driven to move toward the second magnet. In addition, when the moving rod moves, the scraper is driven to move leftward synchronously, thereby releasing the contact between the scraper and the side of the filter screen. S6, when the outer sleeve descends to a third threshold, the outer sleeve moves to the bottom of the reciprocating thread outside the reciprocating screw, at which time the first magnet and the second magnet attract each other, and subsequently as the reciprocating screw continues to rotate, the outer sleeve moves upward and resets, and during the upward movement of the outer sleeve, the outer sleeve plate drives the longitudinal trigger column to reset, and at the same time drives the compressed first reset spring to gradually recover; S7, when the upward movement distance of the outer sleeve reaches the fourth threshold, the compressed first return spring is restored, and as the outer sleeve continues to move upward, the outer sleeve drives the inner sleeve to move upward through the first return spring, and when the inner sleeve moves upward, it moves upward synchronously with the scraper through the inverted U-shaped frame, and the scraper does not rub against the filter screen during the upward movement; S8, when the upward movement distance of the outer sleeve reaches the fifth threshold, the trigger block after moving left contacts the horizontal trigger column. As the outer sleeve continues to move upward, the inclined surface at the bottom of the horizontal trigger column pushes the trigger block, and the trigger block drives the first magnet to separate from the second magnet through the moving rod. In this process, the moving rod drives the scraper after moving left to move right and reset; S9. When the upward movement distance of the outer sleeve reaches the sixth threshold, the outer sleeve arrives at the top of the reciprocating thread on the outside of the second shell, that is, the initial position. At this time, the moving rod has driven the scraper to reset, and the scraper is again in contact with the left wall of the filter. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves down again, and then the next grease cleaning begins.

[0016] Technical effects and advantages of the present invention: The present invention is provided with an oil fume purification mechanism, a transmission driving mechanism, a secondary triggering mechanism and a one-way scraping mechanism, so as to utilize the oil fume purification mechanism to purify the oil fume. During the purification process, the transmission driving mechanism activated by the water flow drives the one-way scraping mechanism to descend, and the one-way scraping mechanism is cleaned during the descent process. Subsequently, the secondary triggering mechanism is driven by the transmission driving mechanism to trigger the one-way scraping mechanism, so that the one-way scraping mechanism no longer contacts the oil fume purification mechanism, and unnecessary friction between the one-way scraping mechanism and the cleaned oil fume purification mechanism is avoided during the subsequent resetting process, so as to prolong the service life of the oil fume purification mechanism and the one-way scraping mechanism. During the resetting process of the one-way scraping mechanism driven by the transmission driving mechanism, the secondary triggering mechanism triggers the one-way scraping mechanism again, thereby restoring the one-way scraping mechanism, so that the oil fume purification mechanism can be cleaned again under the drive of the transmission driving mechanism, thereby shortening the time interval between two adjacent cleaning operations. Compared with the same type of devices and methods in the prior art, the present invention has a higher degree of automation and can utilize the water flow to be atomized to achieve continuous driving, thereby eliminating the need for manual dismantling or manual regular cleaning, saving manpower and being more convenient to use. In addition, due to the short cleaning interval, the stubborn adhesion of grease can be effectively avoided, thereby reducing the operational difficulty of the cleaning process and making the cleaning effect more ideal.

Connected to the bottom ends of multiple water inlet branch pipes 22, multiple guide baffles 27 are staggered and fixed from left to right on the top of the inclined bottom plate 24, the inclined bottom plate 24 is fixed at the bottom of the inner cavity of the first shell 11, the oil guide port 25 is opened at the top of the inclined bottom plate 24, the baffle 26 is fixed at the top of the inclined bottom plate 24 and is located on the left side of the oil guide port 25, the fixed frame 28 is fixed at the top of the inclined bottom plate 24 and is located on the right side of the oil guide port 25, and the filter screen 29 is fixed on the inner side of the fixed frame 28.

[0028] By setting the above-mentioned shell assembly 1 and the oil fume purification mechanism 2, the suction fan inside the smoke inlet pipe 12 can input the oil fume into the first shell 11 through the smoke inlet pipe 12, and the oil fume is continuously transmitted along the channel between two adjacent guide baffles 27. In this process, water flows into the sealing cover 34 through the water supply pipe 35, and then enters into the multiple atomizing nozzles 23 respectively through the water inlet main pipe 21 and the multiple water inlet branch pipes 22, and finally forms water mist in the multiple channels respectively. The water mist performs preliminary purification on the oil fume when the oil fume passes through. The initially purified oil fume passes through the filter 29 for secondary purification, and is then input into the atmosphere under the action of the suction fan inside the smoke outlet pipe 13.

[0029] like Figure 4As shown, the transmission drive mechanism 3 includes a second housing 31, a reciprocating screw 32, an impeller 33, a sealing cover 34, a water supply pipe 35, an outer sleeve 36, a first return spring 37, an inner sleeve 38 and a guide plate 39, wherein the second housing 31 is fixedly arranged on the top of the first housing 11, the reciprocating screw 32 passes through the top of the second housing 31 in the vertical direction and extends to the inside of the second housing 31 and is rotatably connected to the second housing 31 through a bearing, the impeller 33 is fixedly arranged on the top of the reciprocating screw 32, and the sealing cover 34 is sleeved on the outside of the impeller 33 and fixedly arranged on the second housing 3 1 top, the water supply pipe 35 is fixedly arranged at the top center of the sealing cover 34, the outer sleeve 36, the first return spring 37 and the inner sleeve 38 are sleeved and arranged on the outside of the reciprocating screw 32 in sequence from top to bottom, the outer sleeve 36 is transmission-connected with the reciprocating screw 32, the first return spring 37 is fixedly connected between the outer sleeve 36 and the inner sleeve 38, the inner sleeve 38 is slidably connected with the reciprocating screw 32 and is slidably arranged on the inner side of the outer sleeve 36 along the vertical direction, and the guide plate 39 is fixedly sleeved and arranged on the top of the outer side of the outer sleeve 36 and is slidably arranged on the inner side of the second housing 31 along the vertical direction.

[0030] By setting the above structure, when water flows from the water supply pipe 35 into the sealing cover 34, the water flows to drive the impeller 33 to rotate continuously. When the impeller 33 rotates, it drives the reciprocating screw 32 to rotate continuously. When the reciprocating screw 32 rotates, it drives the outer sleeve 36 guided by the guide plate 39 to descend. When the outer sleeve 36 descends, it drives the inner sleeve 38 to descend through the first return spring 37.

[0031] like Figure 4 As shown, the secondary trigger mechanism 4 includes an outer sleeve plate 41, a longitudinal trigger column 42 and a transverse trigger column 43, wherein the outer sleeve plate 41 is fixedly sleeved on the outer bottom end of the outer sleeve 36, the longitudinal trigger column 42 is fixedly arranged at the end of the outer sleeve plate 41, and the transverse trigger column 43 is fixedly arranged on the inner wall of the second shell 31, and the bottom end of the longitudinal trigger column 42 and the bottom of the transverse trigger column 43 are both provided with inclined surfaces.

[0032] By setting the above structure, when the outer sleeve 36 is raised or lowered, the outer sleeve plate 41 drives the longitudinal trigger column 42 to rise or fall, thereby triggering the one-way scraping mechanism 5 twice in succession. The first triggering causes the one-way scraping mechanism 5 to no longer contact the oil fume purification mechanism 2, and the second triggering resets the one-way scraping mechanism 5.

[0033] like Figure 4 and Figure 5As shown, the one-way scraping mechanism 5 includes an inverted U-shaped frame 51, a scraper 52, a guide groove 53, a moving rod 54, a trigger block 55, a second return spring 56, a first magnet 57 and a second magnet 58, wherein the inverted U-shaped frame 51 is fixedly arranged at the bottom end of the inner sleeve 38, the scraper 52 is slidably arranged on the inner side of the inverted U-shaped frame 51 along the horizontal direction and its right end is in contact with the left side of the filter screen 29, the guide groove 53 is opened on the inner side of the inverted U-shaped frame 51 and extends to the top of the inverted U-shaped frame 51, the moving rod 54 is slidably arranged on the inner side of the guide groove 53 along the horizontal direction and is fixedly connected to the scraper 52, the trigger block 55 is fixedly arranged at the top of the moving rod 54, the second return spring 56 is fixedly connected between the inner wall of the guide groove 53 and the side wall of the moving rod 54, the first magnet 57 is fixedly arranged on the left side of the moving rod 54, and the second magnet 58 is fixedly nested on the left side of the guide groove 53 and is colinear with the first magnet 57 in the horizontal direction.

[0034] By setting the above structure, when the inner sleeve 38 descends, the moving rod 54 is driven to descend through the inverted U-shaped frame 51, and when the moving rod 54 descends, the scraper 52 is driven to descend synchronously. During the descent of the scraper 52, the grease attached to the left wall of the filter screen 29 is scraped off, and at the same time, the grease is pushed, so that the grease falls and passes through the oil guide port 25 into the oil-water separator 14 for processing. When the bottom of the inverted U-shaped frame 51 is subsequently attached to the top of the baffle 26, the filter screen 29 is cleaned. At this time, due to the obstruction of the baffle 26, the inverted U-shaped frame 51 cannot continue to descend; After the bottom of the longitudinal trigger column 42 fits with the inclined surface on the right side of the top of the trigger block 55, as the longitudinal trigger column 42 continues to descend, the longitudinal trigger column 42 drives the moving rod 54 to move leftward inside the guide groove 53 through the trigger block 55. When the moving rod 54 moves leftward, it compresses the second return spring 56 and drives the first magnet 57 to move toward the second magnet 58. In addition, when the moving rod 54 moves, it drives the scraper 52 to move leftward synchronously, thereby releasing the contact between the scraper 52 and the side of the filter screen 29 until the first magnet 57 and the second magnet 58 are attracted to each other. When the inner sleeve 38 moves upward, the inverted U-shaped frame 51 and the scraper 52 move upward synchronously, and the scraper 52 does not rub against the filter 29 during the upward movement. In addition, through the one-way cleaning method, while ensuring the cleaning effect, unnecessary friction between the scraper 52 and the cleaned filter 29 during the resetting process is avoided, thereby extending the service life of the filter 29 and the scraper 52. When the trigger block 55 that has subsequently moved left contacts the lateral trigger column 43, as the outer sleeve 36 continues to move upward, the inclined surface at the bottom of the lateral trigger column 43 pushes the trigger block 55, and the trigger block 55 drives the first magnet 57 and the second magnet 58 to disengage through the moving rod 54. During this process, the moving rod 54 drives the scraper 52 that has moved left to move right and reset, thereby facilitating and quickly carrying out the next cleaning operation.

[0035] Example 2

[0036] The method specifically comprises the following steps: S1. The suction fan inside the smoke inlet pipe 12 inputs the oil smoke into the first shell 11 through the smoke inlet pipe 12, and the oil smoke is continuously transmitted along the channel between two adjacent guide baffles 27. During this process, the water flow enters the sealing cover 34 through the water supply pipe 35, and then enters the multiple atomizing nozzles 23 through the water inlet main pipe 21 and the multiple water inlet branch pipes 22, and finally forms water mist in the multiple channels. The water mist performs preliminary purification on the oil smoke when the oil smoke passes through. The initially purified oil smoke passes through the filter 29 for secondary purification, and then is input into the atmosphere under the action of the suction fan inside the smoke outlet pipe 13; S2. When water is inputted into the sealing cover 34 through the water supply pipe 35, the water drives the impeller 33 to rotate continuously. When the impeller 33 rotates, the reciprocating screw 32 rotates continuously. When the reciprocating screw 32 rotates, the outer sleeve 36 guided by the guide plate 39 is driven to descend. When the outer sleeve 36 descends, the inner sleeve 38 is driven to descend through the first return spring 37, and the longitudinal trigger column 42 is driven to descend through the outer sleeve plate 41. S3, when the inner sleeve 38 descends, the moving rod 54 is driven to descend through the inverted U-shaped frame 51, and when the moving rod 54 descends, the scraper 52 is driven to descend synchronously. During the descent process, the scraper 52 scrapes off the grease attached to the left wall of the filter screen 29, and at the same time pushes the grease, so that the grease falls and passes through the oil guide port 25 into the oil-water separator 14 for treatment; S4, when the outer sleeve 36 descends to a first threshold, the bottom of the inverted U-shaped frame 51 is in contact with the top of the stop bar 26, and the filter screen 29 is cleaned. At this time, due to the obstruction of the stop bar 26, the inverted U-shaped frame 51 cannot continue to descend. Subsequently, as the outer sleeve 36 continues to descend, the first return spring 37 is compressed by the inner sleeve 38 which is also unable to descend, and at the same time, the outer sleeve plate 41 continues to drive the longitudinal trigger column 42 to descend; S5, when the outer sleeve 36 descends to a second threshold, the bottom of the longitudinal trigger column 42 fits with the inclined surface on the right side of the top of the trigger block 55. As the longitudinal trigger column 42 continues to descend, the longitudinal trigger column 42 drives the moving rod 54 to move leftward inside the guide groove 53 through the trigger block 55. When the moving rod 54 moves leftward, the second return spring 56 is compressed, and the first magnet 57 is driven to move toward the second magnet 58. In addition, when the moving rod 54 moves, the scraper 52 is driven to move leftward synchronously, so that the scraper 52 is released from contact with the side of the filter screen 29. S6, when the outer sleeve 36 descends to a third threshold, the outer sleeve 36 moves to the bottom of the reciprocating thread on the outer side of the reciprocating screw 32, and the first magnet 57 and the second magnet 58 are attracted to each other. Subsequently, as the reciprocating screw 32 continues to rotate, the outer sleeve 36 moves upward and resets. During the upward movement of the outer sleeve 36, the outer sleeve plate 41 drives the longitudinal trigger column 42 to reset, and at the same time drives the compressed first reset spring 37 to gradually recover. S7, when the upward movement distance of the outer sleeve 36 reaches the fourth threshold, the compressed first return spring 37 is restored, and as the outer sleeve 36 continues to move upward, the outer sleeve 36 drives the inner sleeve 38 to move upward through the first return spring 37, and when the inner sleeve 38 moves upward, it moves upward synchronously with the scraper 52 through the inverted U-shaped frame 51, and the scraper 52 does not rub against the filter screen 29 during the upward movement process; S8, when the upward movement distance of the outer sleeve 36 reaches the fifth threshold, the trigger block 55 after moving left contacts the horizontal trigger column 43. As the outer sleeve 36 continues to move upward, the inclined surface at the bottom of the horizontal trigger column 43 pushes the trigger block 55. The trigger block 55 drives the first magnet 57 to disengage from the second magnet 58 through the moving rod 54. In this process, the moving rod 54 drives the scraper 52 after moving left to move right and reset. S9, when the upward movement distance of the outer sleeve 36 reaches the sixth threshold, the outer sleeve 36 arrives at the top of the reciprocating thread on the outside of the second shell 31, that is, the initial position. At this time, the moving rod 54 has driven the scraper 52 to reset, and the scraper 52 is again in contact with the left side wall of the filter screen 29. Subsequently, as the reciprocating screw 32 continues to rotate, the outer sleeve 36 moves down again, and then the next grease cleaning begins.

8. The oil fume purification method of a commercial oil fume purification integrated machine according to claim 7, characterized in that: The method specifically comprises the following steps: S1, the suction fan inside the smoke inlet pipe (12) inputs the oil smoke into the first shell (11) through the smoke inlet pipe (12), and the oil smoke is continuously transmitted along the channel between two adjacent guide baffles (27). During this process, water flows into the sealing cover (34) through the water supply pipe (35), and then respectively enters the multiple atomizing nozzles (23) through the water inlet main pipe (21) and the multiple water inlet branch pipes (22), and finally forms water mist in the multiple channels. The water mist performs preliminary purification on the oil smoke when the oil smoke passes through. The initially purified oil smoke passes through the filter (29) for secondary purification, and is then input into the atmosphere under the action of the suction fan inside the smoke outlet pipe (13); S2, when water is input from the water supply pipe (35) into the sealing cover (34), the water drives the impeller (33) to rotate continuously, and the impeller (33) drives the reciprocating screw (32) to rotate continuously. When the reciprocating screw (32) rotates, it drives the outer sleeve (36) guided by the guide plate (39) to descend. When the outer sleeve (36) descends, it drives the inner sleeve (38) to descend through the first return spring (37), and drives the longitudinal trigger column (42) to descend through the outer sleeve plate (41); S3, when the inner sleeve (38) descends, the moving rod (54) is driven to descend through the inverted U-shaped frame (51), and when the moving rod (54) descends, the scraper (52) is driven to descend synchronously, and when the scraper (52) descends, the grease attached to the left wall of the filter screen (29) is scraped off, and at the same time, the grease is pushed, so that the grease falls and passes through the oil guide port (25) into the oil-water separator (14) for processing; S4, when the outer sleeve (36) reaches a first threshold value, the bottom of the inverted U-shaped frame (51) is in contact with the top of the stop bar (26), and the filter screen (29) is cleaned. At this time, due to the obstruction of the stop bar (26), the inverted U-shaped frame (51) cannot continue to descend. Subsequently, as the outer sleeve (36) continues to descend, the first return spring (37) is compressed by the inner sleeve (38) which is also unable to descend, and at the same time, the outer sleeve plate (41) continues to drive the longitudinal trigger column (42) to descend; S5, when the outer sleeve (36) descends a distance that reaches a second threshold, the bottom of the longitudinal trigger column (42) fits into the inclined surface on the right side of the top of the trigger block (55), and as the longitudinal trigger column (42) continues to descend, the longitudinal trigger column (42) drives the moving rod (54) to move leftward inside the guide groove (53) through the trigger block (55). When the moving rod (54) moves leftward, the second return spring (56) is compressed, and the first magnet (57) is driven to move in a direction close to the second magnet (58). In addition, when the moving rod (54) moves, the scraper (52) is driven to move leftward synchronously, thereby causing the scraper (52) to release contact with the side of the filter screen (29); S6, when the outer sleeve (36) descends to a third threshold, the outer sleeve (36) moves to the bottom of the reciprocating thread on the outer side of the reciprocating screw (32), and the first magnet (57) and the second magnet (58) are attracted to each other. Subsequently, as the reciprocating screw (32) continues to rotate, the outer sleeve (36) moves upward and resets. During the upward movement of the outer sleeve (36), the outer sleeve plate (41) drives the longitudinal trigger column (42) to reset, and at the same time drives the compressed first reset spring (37) to gradually recover. S7, when the upward movement distance of the outer sleeve (36) reaches a fourth threshold value, the compressed first return spring (37) is restored, and subsequently as the outer sleeve (36) continues to move upward, the outer sleeve (36) drives the inner sleeve (38) to move upward through the first return spring (37), and when the inner sleeve (38) moves upward, it moves upward synchronously with the scraper (52) through the inverted U-shaped frame (51), and the scraper (52) does not rub against the filter screen (29) during the upward movement process; S8, when the upward movement distance of the outer sleeve (36) reaches the fifth threshold value, the trigger block (55) that has moved to the left contacts the transverse trigger column (43), and as the outer sleeve (36) continues to move upward, the inclined surface at the bottom of the transverse trigger column (43) pushes the trigger block (55), and the trigger block (55) drives the first magnet (57) and the second magnet (58) to separate through the moving rod (54). During this process, the moving rod (54) drives the scraper (52) that has moved to the left to move to the right and reset; S9, when the upward movement distance of the outer sleeve (36) reaches the sixth threshold value, the outer sleeve (36) reaches the top of the reciprocating thread on the outside of the second shell (31), that is, the initial position. At this time, the moving rod (54) has driven the scraper (52) to reset, and the scraper (52) is again in contact with the left wall of the filter screen (29). Subsequently, as the reciprocating screw (32) continues to rotate, the outer sleeve (36) moves downward again, and then the next grease cleaning begins.
