Description

Technical Field

[0001] This invention relates to the field of dairy processing equipment, and more specifically, to a milk impurity filtration device with a function of removing air bubbles. Background Technology

[0002] Milk is a complex emulsion mainly composed of water, fat, protein, lactose, minerals, and vitamins. Water accounts for 86% to 90% of its composition. Milk and its products are important sources of protein, calcium, phosphorus, vitamin A, vitamin D, and vitamin B2 in the diet.

[0003] As people's living standards improve, they are paying more and more attention to their diet. Milk is rich in essential nutrients, so many people consume a certain amount of milk daily to meet their nutritional needs. With the increasing demand for milk, traditional milk production is mostly done manually, which is inefficient and clearly unsuitable for modern milk production. Therefore, milk production is now mostly industrialized. However, after milk collection, due to the presence of hair and impurities, the milk needs to be pre-filtered to improve its quality. But existing filters are easily clogged by impurities, which seriously affects the filtration efficiency.

[0004] To address the aforementioned issues, some solutions have been proposed in the prior art. For example, Chinese utility model patent CN219308101U discloses an anti-clogging filter mechanism for milk production. This mechanism works by having a rotating shaft assembly drive a scraper to rotate back and forth after milk is poured into a concave filter tray. A partition plate limits and isolates the scraper. During the scraper's rotation, it pushes impurity particles filtered by the concave filter tray into a collection trough, facilitating the collection of filtered impurities and preventing clogging of the concave filter tray. While existing technologies can collect impurities centrally, preventing their accumulation on the top wall of the filter screen and thus avoiding clogging and reduced milk filtration efficiency, air bubbles are generated in the milk after it is poured into the filter mechanism. These bubbles easily adhere to the filter screen surface after passing through, affecting the speed at which the milk passes through the screen and consequently severely impacting filtration efficiency. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a milk impurity filtration device with a bubble removal function, which can achieve the goal of improving milk filtration efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A milk impurity filtration device with a bubble removal function includes a filter cylinder, a discharge valve inserted on the bottom wall of the filter cylinder, a filter screen for filtering milk inside the filter cylinder, a feed pipe for pouring milk into the filter cylinder inserted on the top wall of the filter cylinder, and a defoaming component inside the filter cylinder.

[0008] The defoaming assembly includes an annular plate fixedly installed on the inner wall of the filter cylinder. A first spring is fixedly installed between the top wall of the annular plate and the filter screen. A motor is installed on the top wall of the filter cylinder, and a rotating rod is fixedly installed on the output end of the motor. Breaking rods for breaking bubbles are evenly fixedly installed on the rotating rod. A cleaning rod is rotatably installed on the top wall of the filter screen, and the rotating rod has a groove that slides with the cleaning rod. An inclined block that cooperates with the cleaning rod is fixedly installed on the side wall of the filter cylinder, and the bottom wall of the inclined block is inclined. A telescopic tube is fixedly installed between the bottom wall of the filter screen and the annular plate, and the telescopic tube can restrict the filter screen from rotating.

[0009] Furthermore, the cleaning rod is provided with an impact groove, the impact groove is provided with an impact hole, the annular plate is provided with an inlet valve communicating with the filter cylinder, the annular plate is provided with a drain valve, the impact groove is provided with a first water pipe, the annular plate is provided with a connecting component communicating with the first water pipe, and the drain valve is connected to the first water pipe through the connecting component.

[0010] Furthermore, the connecting component includes an elastic air cushion fixedly installed on the bottom wall of the annular plate, the elastic air cushion having a cavity, and the output end of the drain valve communicating with the cavity. A horizontal plate cooperating with the rotating rod is fixedly installed on the annular plate, and a cavity is opened on the horizontal plate. A second water pipe communicating with the cavity is inserted into the cavity, and a communicating hole communicating with the first water pipe is opened on the top wall of the cavity.

[0011] Furthermore, a collection box is fixedly installed on the side wall of the filter cartridge, and a collection groove communicating with the filter cartridge is opened on the collection box. A sealing plate is hinged on the collection groove, and a spring is installed on both the sealing plate and the collection box. A first magnet is embedded on the sealing plate, and a second magnet that repels the first magnet is embedded on the cleaning rod.

[0012] Furthermore, the top wall of the sealing plate is provided with an insertion hole, the top wall of the collection box is vertically slidably mounted with a fixing rod, a second spring is installed between the fixing rod and the collection box, the fixing rod is provided with a fixing groove, a limiting rod for limiting the fixing rod is inserted into the side wall of the collection box, a third spring is installed between the limiting rod and the side wall of the collection box, and a drain valve is inserted into the bottom wall of the collection box.

[0013] Furthermore, elastic needles are uniformly fixedly installed on the inner wall of the filter cylinder, and a heating wire electrically connected to the motor is embedded in the impact groove.

[0014] Furthermore, the cleaning rod is provided with uniformly spaced breaking holes.

[0015] Furthermore, multiple connecting holes are evenly distributed.

[0016] Furthermore, the bottom wall of the collection box is inclined, and the bottom wall of the fixing rod is conical.

[0017] Furthermore, the inclined surface of the inclined block is a smooth mirror surface.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) This solution sets up a cleaning rod, which can drive the cleaning rod to rotate and clean the impurities on the top wall of the filter screen during the rotation of the rotating rod. In addition, the cleaning rod can drive the filter screen to shake during the rotation of the cleaning rod. During the shaking of the filter screen, the air bubbles on the top wall of the filter screen can be cut, thereby avoiding the impurities and air bubbles from passing through the filter screen and improving the efficiency of milk filtration.

[0020] (2) This solution uses a telescopic tube to drive milk through the impact hole to impact the air bubbles in the milk during the up-and-down shaking of the filter screen, and to break up the air bubbles. In addition, by setting an elastic air cushion, milk can still be sprayed out through the impact hole during the upward shaking of the filter screen. At the same time, the setting of multiple connecting holes can make the milk spray out intermittently, thereby improving the air bubble elimination effect and effectively preventing air bubbles from adhering to the top wall of the filter screen and affecting the normal passage of milk through the filter screen, thus further improving the milk filtration efficiency.

[0021] (3) This solution uses a collection box. During the rotation of the cleaning rod, the impurities on the top wall of the filter screen can be driven into the collection box through the collection port, thereby avoiding excessive accumulation of impurities on the filter screen and affecting the efficiency of milk passing through the filter screen. As well as the setting of the sealing plate, when there are too many impurities in the collection box, the user can fix the sealing plate with the fixing rod, so that the impurities are cleaned while the milk is being filtered. This prevents the user from stopping the filtration and spending time cleaning the impurities, further improving the filtration efficiency of the milk. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 7 A milk impurity filtration device with a bubble removal function includes a filter cylinder 1, a discharge valve 2 inserted on the bottom wall of the filter cylinder 1, a filter screen 3 for filtering milk inside the filter cylinder 1, a feed pipe 4 for pouring milk into the filter cylinder 1 inserted on the top wall of the filter cylinder 1, and a defoaming component 5 inside the filter cylinder 1.

[0039] The defoaming assembly 5 includes an annular plate 501 fixedly installed on the inner wall of the filter cylinder 1. A first spring 502 is fixedly installed between the top wall of the annular plate 501 and the filter screen 3. A motor 503 is provided on the top wall of the filter cylinder 1. A rotating rod 504 is fixedly installed on the output end of the motor 503. A breaking rod 505 for breaking bubbles is evenly fixedly installed on the rotating rod 504. A cleaning rod 506 is rotatably installed on the top wall of the filter screen 3. A groove 507 is provided on the rotating rod 504 to slide with the cleaning rod 506. An inclined block 508 that cooperates with the cleaning rod 506 is fixedly installed on the side wall of the filter cylinder 1. The bottom wall of the inclined block 508 is inclined. A telescopic tube 509 is fixedly installed between the bottom wall of the filter screen 3 and the annular plate 501. The telescopic tube 509 can restrict the filter screen 3 from rotating.

[0040] The cleaning rod 506 has an impact groove 601 and an impact hole 602. The annular plate 501 is equipped with an inlet valve 603 that communicates with the filter cylinder 1. The annular plate 501 is equipped with a drain valve 604. The impact groove 601 is equipped with a first water pipe 605. The annular plate 501 is equipped with a connecting component 7 that communicates with the first water pipe 605. The drain valve 604 is connected to the first water pipe 605 through the connecting component 7.

[0041] The connecting component 7 includes an elastic air cushion 701 fixedly installed on the bottom wall of the annular plate 501. The elastic air cushion 701 has a cavity 702, and the output end of the drain valve 604 is connected to the cavity 702. A horizontal plate 703 that rotates and cooperates with the rotating rod 504 is fixedly installed on the annular plate 501. A cavity 704 is opened on the horizontal plate 703. A second water pipe 705 connected to the cavity 704 is inserted into the cavity 702. A connecting hole 706 connected to the first water pipe 605 is opened on the top wall of the cavity 704.

[0042] In use, milk is first poured into filter cylinder 1 through feed pipe 4. Filter screen 3 then filters impurities from the milk, and the user can remove the filtered milk through discharge valve 2. Simultaneously, the user can start motor 503, which drives crushing rod 505 to rotate via rotating rod 504. During the rotation of crushing rod 505, air bubbles in the milk are broken up. Simultaneously, the rotation of rotating rod 504 drives cleaning rod 506 to rotate via groove 507. During the rotation of cleaning rod 506, impurities on the top wall of filter screen 3 are cleaned. As cleaning rod 506 rotates, it gradually comes into contact with the inclined surface of inclined block 508. The inclined surface of block 508 drives the cleaning rod 506 to move downward along the groove 507. During the downward movement of the cleaning rod 506, the filter screen 3 moves downward and squeezes the first spring 502. After the cleaning rod 506 disengages from the inclined block 508, the first spring 502 extends and drives the cleaning rod 506 downward along the groove 507 through the filter screen 3. That is, during the cleaning process of the cleaning rod 506 cleaning the filter screen 3, it can also drive the filter screen 3 to shake up and down. During the up and down swing of the filter screen 3, it can cut the air bubbles in the milk again, thereby preventing impurities and attached air bubbles from adhering to the top wall of the filter screen 3 and affecting the speed at which the milk passes through the filter screen 3, thus improving the milk filtration efficiency.

[0043] Because the cleaning rod 506 rotates with the filter screen 3, and the cleaning rod 506 slides with the rotating rod 504 through the groove 507, the telescopic tube 509 can limit the filter screen 3, preventing the rotating cleaning rod 506 from causing the filter screen 3 to rotate and affecting the efficiency of milk passing through the filter screen 3. At the same time, during the up-and-down shaking of the filter screen 3, the telescopic tube 509 extends and retracts back and forth. During the extension of the telescopic tube 509, the space between the outer wall of the telescopic tube 509 and the filter cylinder 1 draws in milk below the filter screen 3 through the liquid inlet valve 603. During the compression of the telescopic tube 509, the milk in the space between the outer wall of the telescopic tube 509 and the filter cylinder 1 flows to the connecting component 7 through the liquid outlet valve 604, and then flows to the impact groove 601 through the connecting component 7 and the first water pipe 605. Then, the milk impacts the air bubbles in the milk through the impact holes 602 on the impact groove 601 and breaks them up. Through the air bubble removal effect, the milk filtration efficiency is further improved, thus preventing air bubbles from affecting the milk filtration efficiency.

[0044] During the contraction of the telescopic tube 509, the milk in the space between the outer wall of the telescopic tube 509 and the filter cylinder 1 flows into the cavity 702 through the drain valve 604, causing the elastic air cushion 701 to expand. Then, the elastic air cushion 701 gradually contracts under its own elastic force, driving the milk in the cavity 702 to flow into the cavity 704 through the second water pipe 705. Then, it flows into the impact groove 601 through the connecting hole 706 on the cavity 704 and the first water pipe 605, and impacts the air bubbles in the milk through the impact hole 602 on the impact groove 601. After the cleaning rod 506 rotates once, The elastic air cushion 701 gradually returns to its normal state. By setting the elastic air cushion 701 with the cavity 702, milk can continuously flow into the cavity 704 through the second air pipe. Even when the filter screen 3 drives the telescopic tube 509 to extend, milk can still continuously flow through the cavity 702, the second water pipe 705, the cavity 704, the connecting hole 706, and the first water pipe 605 to the impact groove 601. The milk then impacts the air bubbles in the milk through the impact holes 602 on the impact groove 601, further improving the air bubble elimination effect and thus further improving the milk filtration efficiency.

[0045] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a collection box 801 is fixedly installed on the side wall of the filter cylinder 1. The collection box 801 has a collection groove that communicates with the filter cylinder 1. A sealing plate 802 is hinged to the collection groove. A spring 803 is installed on both the sealing plate 802 and the collection box 801. A first magnet 804 is embedded in the sealing plate 802. A second magnet 805 that repels the first magnet 804 is embedded in the cleaning rod 506.

[0046] The sealing plate 802 has an insertion hole 901 on its top wall. A fixing rod 902 is vertically and slidably installed on the top wall of the collection box 801. A second spring 903 is installed between the fixing rod 902 and the collection box 801. A fixing groove 904 is provided on the fixing rod 902. A limiting rod 905 for limiting the fixing rod 902 is inserted into the side wall of the collection box 801. A third spring 906 is installed between the limiting rod 905 and the side wall of the collection box 801. A drain valve 907 is inserted into the bottom wall of the collection box 801.

[0047] By adopting the above technical solution, during the rotation of the cleaning rod 506, the second magnet 805 is driven to approach the first magnet 804. When the first magnet 804 and the second magnet 805 are closest, the repulsive force on the first magnet 804 reaches its maximum. Then, under the action of the repulsive force, the first magnet 804 drives the sealing plate 802 to rotate around the hinge point. At this time, the spring 803 begins to store power and has a tendency to return to its original state. During the rotation of the cleaning rod 506, the impurities on the top wall of the filter screen 3 will rotate. Then, under the action of centrifugal force, the impurities move away from the rotating rod 504 and enter the collection box 801 through the collection groove. When the first magnet 804 and the second magnet 805 move away from each other, the spring 803 extends and drives the sealing plate 802 to reset and seal the collection groove again. By collecting the impurities, it is possible to prevent the impurities from re-attaching to the top wall of the filter screen 3 and affecting the milk filtration efficiency, thus improving the milk filtration efficiency.

[0048] Initially, the second spring 903 is in a stretched state, and the third spring 906 is in a freely extended state. When there are too many impurities in the collection box 801, the user can first pull the limiting rod 905, causing it to disengage from the fixing groove 904. At this time, the third spring 906 is stretched. Then, after the limiting rod 905 disengages from the fixing groove 904, the second spring 903 contracts and drives the fixing rod 902 downward. At the same time, as the sealing plate 802 rotates, it drives the insertion hole 901 to rotate. After the insertion hole 901 contacts the fixing rod 902, the second spring 903 drives the fixing rod 902 to insert into the insertion hole 901 and fix the sealing plate 802. At this time, the user can open the drain valve 907. Then, the impurities in the collection box 801 will flow to the outside along with the milk in the collection box 801. After the impurities are cleaned, the user can pull the fixing rod 902 upward. At this time, the second spring 903 is stretched and has a tendency to return to its original state. As the fixing rod 902 moves upward, it drives the fixing groove 904 to gradually contact the limiting rod 905. At this time, the third spring 906 retracts and drives the limiting rod 905 to insert into the fixing groove 904 to fix the fixing rod 902. That is, through the cooperation of the fixing rod 902 and the insertion hole 901, the impurities in the collection box 801 can be cleaned while the milk is being filtered. Therefore, it is not necessary to stop the milk filtration to clean the impurities as in the existing technology, which further improves the milk filtration efficiency.

[0049] like Figure 3 As shown, elastic needles 13 are uniformly fixedly installed on the inner wall of the filter cylinder 1, and a heating wire 11 electrically connected to the motor 503 is embedded in the impact groove 601.

[0050] By adopting the above technical solution, the milk inside the filter cylinder 1 can be rotated during the rotation of the crushing rod 505. Then, the milk rotates, causing the air bubbles inside the milk to rotate. During the rotation of the air bubbles, the elastic needle 13 can cut the air bubbles. As the crushing rod 505 rotates, it gradually comes into contact with the elastic needle 13, causing the elastic needle 13 to deform. Then, when the crushing rod 505 loses contact with the elastic needle 13, the elastic needle 13 vibrates under its own elastic force. During the vibration of the elastic needle 13, the air bubble crushing effect can be improved. At the same time, during the operation of the motor 503, the heating wire starts to work and heats up, thereby heating the milk above the filter screen 3, further improving the air bubble overflow efficiency, and thus further improving the milk filtration efficiency.

[0051] like Figure 7 As shown, the cleaning rod 506 has uniformly opened breaking holes 12.

[0052] By adopting the above technical solution, by opening a breaking hole 12 on the cleaning rod 506, the breaking hole 12 is driven to rotate during the rotation of the cleaning rod 506. During the rotation of the breaking hole 12, the air bubbles above the filter screen 3 can be broken up, so that the air bubbles can overflow the milk, effectively preventing the air bubbles from affecting the normal passage of the milk through the filter screen 3, thereby effectively improving the milk filtration efficiency.

[0053] like Figure 7 As shown, multiple connecting holes 706 are evenly distributed.

[0054] By adopting the above technical solution, and by uniformly opening multiple connecting holes 706, the connecting holes 706 are indirectly connected to the first water pipe 605, so that milk can flow indirectly to the first water pipe 605, thereby allowing the impact hole 602 to spray milk indirectly, which can improve the effect of the milk sprayed by the impact hole 602 on breaking up bubbles.

[0055] like Figure 2 , Figure 5 As shown, the bottom wall of the collection box 801 is inclined, and the bottom wall of the fixing rod 902 is conical.

[0056] By adopting the above technical solution, by making the bottom wall of the collection box 801 sloped, it is easy for impurities in the collection box 801 to flow to the outside through the drain valve 907. By making the bottom wall of the scraper rod conical, the initial contact area between the fixing rod 902 and the insertion hole 901 can be reduced during the process of inserting the fixing rod 902 into the insertion hole 901, thereby facilitating the insertion of the fixing rod 902 into the insertion hole 901.

[0057] like Figure 3 As shown, the inclined surface of the inclined block 508 is a smooth mirror surface.

[0058] By adopting the above technical solution, during the process of the cleaning rod 506 driving the filter screen 3 to move through the inclined block 508, the cleaning rod 506 and the inclined surface of the inclined block 508 will rub against each other. By making the inclined surface of the inclined block 508 a smooth mirror surface, the friction between the inclined surface of the inclined block 508 and the cleaning rod 506 can be reduced, thereby ensuring that the cleaning rod 506 drives the filter screen 3 to move normally through the inclined block 508.

[0059] Instructions for use: First, pour milk into the filter cylinder 1 through the feed pipe 4. Then, the filter screen 3 filters out impurities from the milk. The user can remove the filtered milk through the discharge valve 2. At the same time, the user can start the motor 503. The motor 503 then drives the crushing rod 505 to rotate via the rotating rod 504. During the rotation of the crushing rod 505, air bubbles in the milk are broken up. Simultaneously, the rotating rod 504 also causes the filter screen 3 to vibrate up and down via the cleaning rod 506, cutting the air bubbles in the milk. During the operation, the telescopic tube 509 extends and retracts, causing the milk in the space between the outer wall of the telescopic tube 509 and the filter cylinder 1 to flow through the drain valve 604 to the connecting component 7, and then through the connecting component 7 and the first water pipe 605 to the impact tank 601. The milk then impacts the air bubbles in the milk through the impact holes 602 on the impact tank 601, breaking them up. As the cleaning rod 506 rotates, it causes the impurities on the top wall of the filter screen 3 to rotate. Under the action of centrifugal force, the impurities move away from the rotating rod 504 and enter the collection box 801 through the collection tank. When the impurities in the collection box 801... When there is excessive sediment, the user can first pull the limiting rod 905, causing it to disengage from the fixing groove 904. At this time, the third spring 906 is stretched. Then, after the limiting rod 905 disengages from the fixing groove 904, the second spring 903 contracts and drives the fixing rod 902 downward. Simultaneously, as the sealing plate 802 rotates, it drives the insertion hole 901 to rotate. After the insertion hole 901 contacts the fixing rod 902, the second spring 903 drives the fixing rod 902 to insert into the insertion hole 901, thus fixing the sealing plate 802. At this point, the user can open the drain valve 907. Then, the impurities in the collection box 801 will flow to the outside along with the milk in the collection box 801. After the impurities are cleaned, the user can pull the fixing rod 902 upward. At this time, the second spring 903 is stretched and has a tendency to return to its original state. As the fixing rod 902 moves upward, it drives the fixing groove 904 to gradually contact the limiting rod 905. At this time, the third spring 906 contracts and drives the limiting rod 905 to insert into the fixing groove 904 to fix the fixing rod 902. That is, through the cooperation of the fixing rod 902 and the insertion hole 901, the impurities in the collection box 801 can be cleaned while filtering the milk.

[0060] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
