Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to a tea oil filtering equipment used for tea oil production. Background Art

[0002] The filtering equipment in tea oil production is mainly used to remove impurities in the oil, purify the tea oil, and ensure the quality of the tea oil. The filtering equipment is generally equipped with a filter element. During the filtration, a filter cake is generally formed on the filter element. The formation of the filter cake helps to improve the filtration efficiency. The filter cake acts as an additional filter layer, which can intercept finer particles and make the filtration process smoother.

[0003] During the filtration process, the filter cake on the filter element will gradually thicken as impurities gradually accumulate. When the filter cake is too thick, the filtration performance will drop significantly, which will reduce the filtration efficiency. A thicker filter cake can be scraped into a filter cake of moderate thickness by a scraper, but during the process of filtering and purifying tea oil, the filter cake is scraped off. During the scraping process, due to the effect of flowing oil, the filter cake fragments that have just been scraped off may be re-attached to the filter element under the action of the oil flow. This situation is particularly obvious when the oil flow rate is high. This will make the effect of scraping the filter cake not obvious during high-speed filtration, resulting in the thickness of the filter cake being difficult to control during the continuous purification and filtration of tea oil. The filter cake is prone to being too thick, resulting in a decrease in the purification and filtration efficiency of tea oil. Summary of the invention

DETAILED DESCRIPTION

[0040] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] Embodiment 1, as Figures 1 to 17As shown, a tea oil filtering device for tea oil production proposed by the present invention comprises a tank body 1, a liquid inlet 101 is provided on the top of the tank body 1 and a liquid outlet 102 is provided on the bottom, a filter element 2 is fixedly installed in the tank body 1, and when filtering the tea oil, the tea oil first needs to be input into the tank body 1 through the liquid inlet 101, and the tea oil will enter the interior of the filter element 2 through the filter element 2 and be discharged through the liquid outlet 102, so that the filtration and purification of the tea oil can be completed, but the impurities in the tea oil will not be able to pass through the filter element 2, and will gradually adhere to the filter element 2 to form a filter cake, and the present embodiment also includes a filter element cleaning component installed in the tank body 1, and the filter element cleaning component includes a plurality of scraping components, and the scraping component includes a scraper 4 for scraping impurities on the filter element 2, a cleaning knife 401 for scraping adhesions on the scraper 4, and a collection box 402 for collecting impurities detached from the filter element 2, and a power mechanism for driving the filter element cleaning component to rotate in the tank body 1 is installed on the tank body 1. A plurality of scrapers 4 are driven to rotate in the tank body 1 by a power mechanism, so that the scrapers 4 are attached to the filter cake and the rotating scrapers 4 can scrape the filter cake. In the process of scraping the filter cake, grease will adhere to the scraper 4, which may make the scraper 4 blunt. A blunt scraper 4 may cause damage to the filter cake when scraping the filter cake, affecting the filtering effect and product quality. The adhesion on the scraper 4 can be scraped off by a cleaning knife 401 to keep the scraper 4 sharp.

[0042] Furthermore, the power mechanism includes a turntable 3 and a support ring 301 rotatably installed in the tank body 1, a filter element cleaning component is installed between the turntable 3 and the support ring 301, a transmission shaft 302 is fixedly installed on the turntable 3, a motor 303 is fixedly installed on the top of the tank body 1, and the output shaft of the motor 303 is coaxially fixedly connected with the transmission shaft 302. The scraper 4 and the cleaning knife 401 are both slidably connected with the turntable 3 and the support ring 301, and the collection box 402 is fixedly installed between the turntable 3 and the support ring 301. The motor 303 can drive the turntable 3 to rotate through the transmission shaft 302, and the rotating turntable 3 can drive the scraper 4, the cleaning knife 401 and the collection box 402 to move synchronously, so that the scraper 4 can move in a circle around the filter element 2, and then the filter cake on the filter element 2 can be scraped off.

[0043] The tea oil filtering device of the present embodiment also includes a filter cake control module, which is installed inside the tank body 1. The filter cake control module includes a zoom mechanism that controls multiple scrapers 4 and cleaning blades 401 to shrink or expand synchronously with the axis of the tank body 1 as the center. Due to the different filter cake thicknesses required when filtering different media, such as thin filter cakes, medium filter cakes and thick filter cakes, thin filter cakes are 0.5 mm to 2 mm thick and are generally considered to be thinner filter cakes, suitable for occasions requiring high filtration rate and low resistance. Medium filter cakes are medium-thick filter cakes with a thickness of 2 mm to 5 mm, which are suitable for most industrial filtration operations, and thick filter cakes are filter cakes of more than 5 mm that are considered to be thicker, and this thickness may reduce the filtration rate, but can increase the capture of solid matter. Therefore, in the actual operation process, it is necessary to adjust the position of the scraper 4 according to the filtering requirements of the reagent so that the scraper 4 can adapt to filter cakes of different thicknesses.

[0044] Among them, the zoom mechanism includes a driving ring 5 rotatably installed on the turntable 3, a plurality of first connecting rods 501 are rotatably installed on the driving ring 5, a plurality of first sliding grooves 502 are provided on the turntable 3, a first slider 503 is slidably installed in the first sliding groove 502, the first slider 503 corresponds to the scraper 4 one-to-one and is fixedly connected, the first connecting rod 501 corresponds to the first slider 503 one-to-one and is rotatably connected, a plurality of second connecting rods 504 are rotatably installed on the turntable 3, a plurality of second sliding grooves 505 are provided on the turntable 3, a second slider 506 is slidably installed in the second sliding groove 505, the second slider 506 corresponds to the cleaning knife 401 one-to-one and is rotatably connected, and the second connecting rod 504 corresponds to the second slider 506 one-to-one and is rotatably connected. When the driving ring 5 rotates, the rotating driving ring 5 will drive the first connecting rod 501 and the second connecting rod 504 to rotate synchronously, and the rotating first connecting rod 501 and the second connecting rod 504 will push the first slider 503 and the second slider 506 to move along the first slide groove 502 and the second slide groove 505 respectively, and then the scraper 4 and the cleaning knife 401 can be driven to move by the first slider 503 and the second slider 506 respectively, and then the position of the scraper 4 can be adjusted, and the thickness of the filter cake on the filter element 2 can be controlled according to actual conditions, so as to achieve a better purification purpose for the tea oil.

[0045] In this embodiment, a positioning assembly is installed between the turntable 3 and the drive ring 5, and the positioning assembly controls whether the turntable 3 and the drive ring 5 can rotate relative to each other. A stacking assembly for driving the drive ring 5 to rotate on the turntable 3 is installed on the tank body 1. Since the drive ring 5 and the turntable 3 are rotatably connected, when there is no need to adjust the position of the scraper 4, the turntable 3 and the drive ring 5 should be fixedly connected, so that the drive ring 5 rotates with the turntable 3 under the action of the motor 303, and when the position of the scraper 4 needs to be adjusted, the drive ring 5 needs to be rotated on the turntable 3, and the drive ring 5 is driven to rotate through the stacking assembly to achieve the purpose of adjusting the position of the scraper 4.

[0046] Furthermore, the positioning assembly includes a connecting sleeve 6 fixedly mounted on the driving ring 5, the transmission shaft 302 is located inside the connecting sleeve 6 and is rotatably connected, a first connecting block 601 is rotatably mounted on the transmission shaft 302, a second connecting block 602 is rotatably mounted on the connecting sleeve 6, an oil barrel 603 is fixedly mounted on the second connecting block 602, a sealing block 604 is slidably mounted in the oil barrel 603, a positioning rod 605 is fixedly mounted on the sealing block 604, the positioning rod 605 passes through one side of the oil barrel 603 and is fixedly connected to the first connecting block 601, oil pipes 606 are installed on the upper and lower sides of the oil barrel 603, electric control valves 607 are fixedly mounted on the two oil pipes 606, and the oil barrel 603 and the oil pipes 606 are filled with hydraulic oil. When the electric control valve 607 is in a closed state, the hydraulic oil on the upper and lower sides of the sealing block 604 will not be able to communicate with each other. At this time, the sealing block 604 will not be able to slide in the oil barrel 603, and the distance between the first connecting block 601 and the second connecting block 602 cannot be adjusted. When the drive ring 5 and the turntable 3 need to rotate relative to each other, the transmission shaft 302 and the connecting sleeve 6 will rotate relative to each other. The relatively rotating transmission shaft 302 and the connecting sleeve 6 will drive the first connecting block 601 and the second connecting block 602 to move, which will change the distance between the first connecting block 601 and the second connecting block 602. Due to the closed state of the electric control valve 607, the spacing between the first connecting block 601 and the second connecting block 602 will not be changed, so that the drive ring 5 and the turntable 3 can be kept in a fixed state. When the electric control valve 607 is opened, the hydraulic oil on both sides of the sealing block 604 can circulate with each other, which will make the distance between the first connecting block 601 and the second connecting block 602 adjustable, so that the drive ring 5 and the turntable 3 remain in a state of rotational connection.

[0047] Furthermore, the stacking assembly includes a transmission rod 608 fixedly mounted on the connecting sleeve 6, a push rod motor 609 is rotatably mounted on the tank body 1, and the output shaft of the push rod motor 609 is rotatably connected to the transmission rod 608. When the position of the scraper 4 needs to be adjusted, the electric control valve 607 is first opened, and then the push rod motor 609 is extended or retracted, so that the connecting sleeve 6 can be driven to rotate through the transmission rod 608, and then the driving ring 5 is rotated.

[0048] Among them, a driving assembly for driving the cleaning knife 401 to rotate is installed in the tank body 1, and the driving assembly includes a first friction wheel 507 rotatably installed on the second slider 506 and coaxially fixedly connected with the cleaning knife 401. A plurality of first telescopic rods 508 are fixedly installed in the tank body 1, and an arc-shaped friction track 509 is fixedly installed on the first telescopic rod 508, and the first friction wheel 507 abuts against the arc-shaped friction track 509. Through the action of the friction force between the first friction wheel 507 and the arc-shaped friction track 509, when the first friction wheel 507 rotates with the turntable 3, it will rotate under the action of the friction force between the first friction wheel 507 and the arc-shaped friction track 509, and then the cleaning knife 401 fixedly connected thereto can be driven to rotate, and the rotating cleaning knife 401 can scrape off the adhesion on the scraper 4, so that the scraper 4 can be kept sharp, avoiding damage to the filter cake when scraping off the filter cake, and preventing the filtering and purification effect of the tea oil and the product quality from being affected. A plurality of third connecting rods 510 are rotatably mounted on the turntable 3, and the third connecting rods 510 correspond to the arc-shaped friction track 509 one by one and are rotatably connected. Through the action of the third connecting rods 510, the position of the arc-shaped friction track 509 can be adjusted while adjusting the position of the scraper 4, so that the first friction wheel 507 can always be against the arc-shaped friction track 509. The first friction wheel 507 here can also use a gear, and the arc-shaped friction track 509 can use an arc-shaped rack, and the gear and the arc-shaped rack are meshed with each other. This method can make the rotation of the cleaning knife 401 more stable.

[0049] It should be noted that a screen 405 is slidably installed in the collection box 402, and both sides of the collection box 402 are provided with an opening and closing component for controlling the opening and closing state of the two sides of the collection box 402 according to the moving state of the collection box 402. The opening and closing component includes two sealing plates 403 rotatably installed on both sides of the collection box 402, and an elastic connecting member 404 is fixedly installed on the sealing plate 403. The other end of the elastic connecting member 404 is fixedly connected to the inner wall of the collection box 402, and the bottom of the collection box 402 is connected to the outside. When the impurities on the filter cake are scraped off by the scraper 4, they will enter the collecting box 402 located behind the scraper 4. When the collecting box 402 rotates with the turntable 3, the tea oil will be pushed to move, and the tea oil will apply a thrust to the sealing plate 403 to rotate the sealing plate 403, so that both sides of the collecting box 402 can be in an open state. At this time, the tea oil will pass through the collecting box 402 and the screen 405 inside the collecting box 402, and the scraped impurities will be resisted by the screen and will adhere to the screen 405 under the thrust of the tea oil, thereby effectively preventing the impurities scraped off by the scraper 4 from adhering to the filter cake again under the action of the flow of tea oil, thereby effectively ensuring the accuracy of the filter cake thickness control and the stability of the tea oil during filtration and purification. When the turntable 3 stops rotating, that is, the collecting box 402 does not rotate, the sealing plates 403 on both sides will seal the collecting box 402 again under the action of the elastic connecting piece 404. At this time, even if the tea oil continues to be filtered and purified, the flowing tea oil cannot interfere with the impurities in the collecting box 402. At this time, the impurities inside the collecting box 402 will move downward under the action of gravity.

[0050] Furthermore, an oscillating mechanism is installed in the tank body 1 to drive the screen 405 to vibrate when the collection box 402 moves. As the amount of tea oil filtered increases, the impurities accumulated on the screen 405 will gradually increase. In order to ensure that the impurities in the collection box 402 can automatically move downward and separate from the screen 405 under the action of gravity after the two sides of the collection box 402 are closed, the screen 405 needs to be kept in a vibrating state to prevent the impurities from sticking to the screen 405 and unable to separate under the action of gravity.

[0051] Among them, the oscillation mechanism includes a plurality of third slide grooves 511 arranged on the turntable 3, a third slider 512 is slidably installed inside the third slide grooves 511, the third slider 512 corresponds to the screen 405 one by one and is fixedly connected, a first slide bar 513 is rotatably installed on the third slider 512, a slide sleeve 514 is slidably installed on the first slide bar 513, the middle part of the slide sleeve 514 is rotatably connected to the turntable 3, a second slide bar 515 is slidably installed on the other end of the slide sleeve 514, a plurality of second friction wheels 516 are rotatably installed on the turntable 3, the second friction wheels 516 correspond to the second slide bar 515 one by one and are eccentrically rotatably connected, a friction ring 517 is fixedly installed on the tank body 1, and the second friction wheel 516 abuts against the friction ring 517. When the turntable 3 rotates, it will drive the second friction wheel 516 to rotate, and under the action of the friction force between the second friction wheel 516 and the friction ring 517, the second friction wheel 516 can rotate on its own. The second friction wheel 516 here can be replaced by a gear, and the friction ring 517 can be replaced by a gear ring, so as to achieve a better transmission effect, so that the second friction wheel 516 can drive the sliding sleeve 514 to swing back and forth through the second sliding rod 515. At this time, the reciprocating sliding sleeve 514 will drive the screen 405 to slide back and forth along the third sliding groove 511 through the transmission of the first sliding rod 513, so that the screen 405 is always in an oscillating state when capturing impurities, which can prevent impurities from sticking to the screen 405 and being unable to detach. When scraping the filter cake, it only needs to periodically drive the turntable 3 through the motor 303 to make the impurities periodically enter the collection box 402 and settle downward under the action of gravity.

[0052] In this embodiment, a waste residue discharge mechanism is installed at the bottom of the tank body 1, and the waste residue discharge mechanism discharges the waste residue collected by the collection box 402 to the outside of the tank body 1. The waste residue discharge mechanism includes a waste residue collection tank 7 arranged in the tank body 1, and a discharge hole 701 is provided on the waste residue collection tank 7. A cleaning plate 702 is fixedly installed on the support ring 301, and a discharge pipe 703 is fixedly installed on the discharge hole 701. The discharge pipe 703 passes through the bottom of the tank body 1 and extends to the outside of the tank body 1. A discharge valve 704 is fixedly installed on the discharge pipe 703. The impurities settled in the collection box 402 will enter the waste residue collection tank 7, and the support ring 301 will rotate with the rotation of the turntable 3, so that the support ring 301 drives the cleaning plate 702 to move. The cleaning plate 702 can push the impurities entering the waste residue collection tank 7, so that the impurities entering the waste residue collection tank 7 are pushed into the discharge hole 701, and finally enter the discharge pipe 703 and accumulate in the discharge pipe 703. At this time, opening the discharge valve 704 can discharge the impurities through the discharge pipe 703 to the outside of the tank body 1 under the action of the internal hydraulic pressure, so that the tea oil can be continuously filtered to improve the efficiency of tea oil production and purification.

[0053] The working principle of this embodiment is as follows: when filtering and purifying tea oil, the tea oil first needs to be input into the tank body 1 through the liquid inlet 101, and the tea oil will enter the interior of the filter element 2 through the filter element 2 and be discharged through the liquid outlet 102, thereby completing the filtering and purification of the tea oil. However, the impurities in the tea oil will not be able to pass through the filter element 2, and will gradually adhere to the filter element 2 to form a filter cake. The motor 303 can drive the turntable 3 to rotate through the transmission shaft 302, and the rotating turntable 3 can drive the scraper 4, the cleaning knife 401 and the collection box 402 to move synchronously, so that the scraper 4 can move in a circle around the filter element 2, and the filter cake on the filter element 2 can be scraped off.

[0054] When the driving ring 5 rotates, the rotating driving ring 5 will drive the first connecting rod 501 and the second connecting rod 504 to rotate synchronously, and the rotating first connecting rod 501 and the second connecting rod 504 will push the first slider 503 and the second slider 506 to move along the first slide groove 502 and the second slide groove 505 respectively, and then the scraper 4 and the cleaning knife 401 can be driven to move by the first slider 503 and the second slider 506 respectively, and then the position of the scraper 4 can be adjusted, and the thickness of the filter cake on the filter element 2 can be controlled according to actual conditions, so as to achieve a better purification purpose for the tea oil.

[0055] After the impurities on the filter cake are scraped off by the scraper 4, they will enter the collection box 402 located behind the scraper 4. When the turntable 3 stops rotating, that is, the collection box 402 does not rotate, the sealing plates 403 on both sides will seal the collection box 402 again under the action of the elastic connecting piece 404. At this time, even if the tea oil continues to be filtered and purified, the flowing tea oil cannot interfere with the impurities in the collection box 402. At this time, the impurities in the collection box 402 will move downward under the action of gravity. The impurities settled in the collection box 402 will enter the waste residue collection tank 7. The impurities entering the waste residue collection tank 7 can be pushed by the cleaning plate 702, so that the impurities entering the waste residue collection tank 7 are pushed into the discharge hole 701, and finally enter the discharge pipe 703 and accumulate in the discharge pipe 703. At this time, the discharge valve 704 can be opened to discharge the impurities to the outside of the tank body 1 through the discharge pipe 703 under the action of the internal hydraulic pressure, so that the tea oil can be continuously filtered to improve the efficiency of tea oil production and purification.

[0056] Embodiment 2, as Figures 1 to 3As shown, based on the first embodiment, a self-cleaning mechanism for crushing and removing the filter cake is installed on the tank body 1, and the self-cleaning mechanism includes an electric valve 8 fixedly installed on the liquid outlet 102, and an air inlet 801 arranged on the electric valve 8, and the air inlet 801 is connected to an external air source. After the tea oil is completely filtered, the filter cake on the filter element 2 needs to be thoroughly removed. At this time, the electric valve 8 can be opened, and the gas is transported into the tank body 1 through the external air source. At this time, one end of the liquid outlet 102 needs to be blocked, and a valve can be set for blocking, or the component connected to the liquid outlet 102 can be blocked. At this time, the gas will enter the tank body 1 and blow from the inside of the filter element 2 to the outside. At this time, the filter cake on the filter element 2 will gradually dry and crack, and will gradually separate from the filter element 2. At this time, the scraper 4 can also be used in conjunction to scrape the filter cake with the scraper 4.

[0057] Furthermore, a spray head 803 is fixedly installed on the top of the tank body 1, and a spray port 802 is connected to the spray head 803. By conveying cleaning liquid into the spray port 802, the cleaning liquid can be sprayed on the inside of the tank body 1, and the inside of the tank body 1 and the filter element 2 can be further cleaned.

[0058] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
