Description

Technical Field

[0001] The invention relates to the field of dairy product processing equipment, and more particularly to a milk impurity filtering device with a bubble removing function. Background Art

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

[0003] As people's living standards improve, they pay more and more attention to diet, and milk is rich in a large number of essential nutrients for the human body, so many people will consume a certain amount of milk every day to meet daily nutritional needs. With the growing demand for milk, traditional milk production is mostly manual, and the efficiency of this kind of milk production is too low, which is obviously not suitable for modern milk demand. Therefore, most of the current milk production is industrialized. However, after the milk is collected, since hair and impurities are mixed in the milk, in order to improve the quality of the milk, after the milk is collected, it is necessary to perform preliminary filtration on the milk through a filtration device, but the existing filtration device is easily clogged by impurities, which seriously affects the filtration efficiency of the milk.

[0004] In view of the above problems, some solutions are also provided in the prior art. For example, the Chinese utility model patent with announcement number CN219308101U discloses an anti-clogging filtering mechanism for milk production. By setting the anti-clogging filtering mechanism, after the milk is poured into the concave filter disc, the rotating shaft assembly drives the slag collecting scraper to rotate back and forth, and the isolation plate is used for limiting and isolating the slag collecting scraper. During the back-and-forth rotation of the slag collecting scraper, the impurity particles filtered out by the concave filter disc are pushed into the slag collecting trough, which is convenient for collecting the impurities after filtration and preventing the concave filter disc from being blocked. Although the prior art can collect impurities in a centralized manner, thereby avoiding the accumulation of impurities on the top wall of the filter screen and causing the filter screen to be blocked and affect the filtering efficiency of the milk, bubbles will be generated in the milk after the milk is poured into the filtering mechanism, and then after the milk passes through the filter screen, the bubbles are easily attached to the surface of the filter screen, thereby affecting the speed at which the milk passes through the filter screen, which will seriously affect the filtering efficiency of the milk.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution provides a cleaning rod, which can drive the cleaning rod to rotate and clean impurities on the top wall of the filter screen during the rotation of the rotating rod, and can drive the filter screen to shake during the rotation of the cleaning rod.

At the same time, the provision of multiple connecting holes can make the milk ejected intermittently, thereby improving the bubble elimination effect, effectively preventing the bubbles from adhering to the top wall of the filter screen and affecting the normal passage of the milk through the filter screen, and further improving the filtering efficiency of the milk.

[0021] (3) This solution uses a collection box. During the rotation of the cleaning rod, the impurities on the top wall of the filter can be driven into the collection box through the collection port, thereby preventing the filter from accumulating too much impurities and affecting the efficiency of milk passing through the filter. In addition, the blocking plate is set. When there are too many impurities in the collection box, the user can fix the blocking plate with a fixing rod, so that the impurities can be cleaned while filtering the milk. In this way, the user does not need to stop filtering and spend time cleaning the impurities, which further improves the filtering efficiency of the milk. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The debubble assembly 5 includes an annular plate 501 fixedly mounted on the inner wall of the filter cartridge 1, a first spring 502 is fixedly mounted 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 cartridge 1, a rotating rod 504 is fixedly mounted on the output end of the motor 503, a crushing rod 505 for crushing bubbles is evenly fixedly mounted on the rotating rod 504, a cleaning rod 506 is rotatably mounted on the top wall of the filter screen 3, and a groove 507 for slidingly cooperating with the cleaning rod 506 is formed on the rotating rod 504, an inclined block 508 cooperating with the cleaning rod 506 is fixedly mounted on the side wall of the filter cartridge 1, and the bottom wall of the inclined block 508 is an inclined surface, a telescopic tube 509 is fixedly mounted between the bottom wall of the filter screen 3 and the annular plate 501, and the telescopic tube 509 can limit the filter screen 3 from rotating.

[0040] An impact groove 601 is provided on the cleaning rod 506, an impact hole 602 is provided on the impact groove 601, an inlet valve 603 connected to the filter cartridge 1 is inserted on the annular plate 501, a drain valve 604 is inserted on the annular plate 501, a first water pipe 605 is inserted on the impact groove 601, a connecting component 7 connected to the first water pipe 605 is provided on the annular plate 501, and 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 mounted on the bottom wall of the annular plate 501, a cavity 702 is provided on the elastic air cushion 701, and the output end of the drain valve 604 is connected with the cavity 702, a horizontal plate 703 is fixedly mounted on the annular plate 501 and rotatably cooperates with the rotating rod 504, a cavity 704 is provided on the horizontal plate 703, a second water pipe 705 connected with the cavity 704 is inserted in the cavity 702, and a connecting hole 706 connected with the first water pipe 605 is provided on the top wall of the cavity 704.

[0042] When in use, first pour the milk into the filter cartridge 1 through the feed pipe 4, then the filter screen 3 can filter the impurities in the milk, and the user can take out the filtered milk through the discharge valve 2. At the same time, the user can start the motor 503, and then the motor 503 drives the crushing rod 505 to rotate through the rotating rod 504, and the bubbles in the milk can be broken up during the rotation of the crushing rod 505, and the cleaning rod 506 can be driven to rotate through the groove 507 during the rotation of the rotating rod 504, and then the impurities on the top wall of the filter screen 3 can be cleaned during the rotation of the cleaning rod 506, and at the same time, the cleaning rod 506 gradually contacts the inclined surface of the inclined block 508 during the rotation, and then the inclined block 508 is rotated. The inclined surface of 08 drives the cleaning rod 506 to move downward along the groove 507. In the process of the cleaning rod 506 moving downward, it drives the filter 3 to move downward and squeezes the first spring 502. When the cleaning rod 506 is out of contact with the inclined block 508, the first spring 502 stretches and drives the cleaning rod 506 to move downward along the groove 507 through the filter 3. That is, in the process of the cleaning rod 506 cleaning the filter 3, it can also drive the filter 3 to shake up and down, and then in the process of the filter 3 swinging up and down, the bubbles in the milk can be cut again, thereby avoiding impurities and bubbles adhering to the top wall of the filter 3, affecting the speed of milk passing through the filter 3, and playing a role in improving the milk filtration efficiency.

[0043] Since the cleaning rod 506 is in rotational cooperation with the filter screen 3, and the cleaning rod 506 is in sliding cooperation with the rotating rod 504 through the groove 507, the filter screen 3 can be limited by setting the telescopic tube 509 to prevent the rotating cleaning rod 506 from driving the filter screen 3 to rotate and affecting the efficiency of milk passing through the filter screen 3. At the same time, the telescopic tube 509 is driven to extend and retract back and forth during the up and down shaking of the filter screen 3. Then, during the extension of the telescopic tube 509, the space between the outer wall of the telescopic tube 509 and the filter cartridge 1 absorbs the milk under the filter screen 3 through the liquid inlet valve 603. Then, 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 cartridge 1 flows to the connecting component 7 through the drain valve 604, and flows to the impact groove 601 through the connecting component 7 and the first water pipe 605, and then impacts the bubbles in the milk through the impact hole 602 on the impact groove 601 and breaks up the bubbles. Further, through the bubble removal effect, the bubbles are further prevented from affecting the milk filtering efficiency, thereby further improving the milk filtering 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 cartridge 1 flows into the cavity 702 through the drain valve 604, and expands the elastic air cushion 701. Then, the elastic air cushion 701 gradually contracts under the action of its own elastic force, and drives the milk in the cavity 702 to flow into the cavity 704 through the second water pipe 705, and then flows to the impact groove 601 through the connecting hole 706 on the cavity 704 and the first water pipe 605, and impacts the bubbles in the milk through the impact hole 602 on the impact groove 601. After the cleaning rod 506 rotates one circle, The elastic air cushion 701 gradually returns to a normal state, that is, by providing the elastic air cushion 701 with a cavity 702, the milk can continuously flow into the cavity 704 through the second air pipe, that is, when the filter 3 drives the telescopic tube 509 to extend, the milk can still continuously flow to the impact groove 601 through the cavity 702, the second water pipe 705, the cavity 704, the connecting hole 706, and the first water pipe 605, and impact the bubbles in the milk through the impact hole 602 on the impact groove 601, thereby further improving the bubble elimination effect, thereby further improving the milk filtering efficiency.

[0045] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a collecting box 801 is fixedly installed on the side wall of the filter cartridge 1, a collecting groove connected to the filter cartridge 1 is opened on the collecting box 801, a sealing plate 802 is hinged on the collecting groove, a spring 803 is installed on the sealing plate 802 and the collecting box 801, a first magnet 804 is embedded in the sealing plate 802, and a second magnet 805 that repel each other with the first magnet 804 is embedded in the cleaning rod 506.

[0046] A plug hole 901 is provided on the top wall of the blocking plate 802, a fixing rod 902 is vertically slidably installed on the top wall of the collecting box 801, a second spring 903 is installed between the fixing rod 902 and the collecting 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 on the side wall of the collecting box 801, a third spring 906 is installed between the limiting rod 905 and the side wall of the collecting box 801, and a drain valve 907 is inserted on the bottom wall of the collecting 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, and when the first magnet 804 and the second magnet 805 are closest, the repulsive force on the first magnet 804 reaches the maximum, and then under the action of the repulsive force, the first magnet 804 drives the blocking plate 802 to rotate around the hinge point. At this time, the spring 803 begins to accumulate power and has a tendency to recover, and during the rotation of the cleaning rod 506, it will drive the impurities on the top wall of the filter screen 3 to rotate, and then under the action of centrifugal force, the impurities move in the direction 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 are away from each other, the spring 803 stretches and drives the blocking plate 802 to reset and block the collection groove again. By collecting impurities, it is possible to prevent the impurities from adhering to the top wall of the filter screen 3 again and affecting the filtration efficiency of the milk, thereby improving the filtration efficiency of the milk.

[0048] In the initial state, the second spring 903 is in a stretched state, and the third spring 906 is in a freely stretched state. When there are too many impurities in the collection box 801, the user can first pull the limiting rod 905 to make the limiting rod 905 disengage from the fixing groove 904. At this time, the third spring 906 is stretched, and then after the limiting rod 905 disengages from the fixing groove 904, the second spring 903 contracts and drives the fixing rod 902 to move downward. At the same time, the plug hole 901 is driven to rotate during the rotation of the blocking plate 802. After the plug hole 901 contacts the fixing rod 902, the second spring 903 drives the fixing rod 902 to be inserted into the plug hole 901 and fixes the blocking plate 802. At this time, the user can open the drain valve 907. , and then the impurities in the collection box 801 will flow to the outside together with the milk in the collection box 801. When the impurities are cleaned, the user can pull the fixing rod 902 upwards. At this time, the second spring 903 is stretched and has a tendency to recover. In the process of the fixing rod 902 moving upwards, the fixing groove 904 is driven 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 socket 901, the impurities in the collection box 801 can be cleaned while the milk is filtered, so there is no need to stop the filtration of the milk to clean the impurities as in the prior art, which further improves the filtration efficiency of the milk.

[0049] like Figure 3 As shown, elastic needles 13 are evenly and fixedly installed on the inner wall of the filter cartridge 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 scheme, the milk in the filter cylinder 1 can be driven to rotate during the rotation of the breaker rod 505, and then the bubbles inside the milk can be driven to rotate during the rotation of the milk, and then the elastic needle 13 can cut the bubbles during the rotation of the bubbles, and the breaker rod 505 will gradually contact the elastic needle 13 during the rotation, and cause the elastic needle 13 to deform, and then when the breaker rod 505 is out of contact with the elastic needle 13, the elastic needle 13 shakes under the action of its own elastic force, and the bubble breaking effect can be improved during the shaking of the elastic needle 13. At the same time, during the operation of the motor 503, the heating wire starts to work and generates heat, so that the milk above the filter net 3 can be heated, further improving the bubble overflow efficiency, thereby further improving the milk filtration efficiency.

[0051] like Figure 7 As shown, the cleaning rod 506 is evenly provided with crushing holes 12 .

[0052] By adopting the above technical solution, by opening the crushing hole 12 on the cleaning rod 506, the crushing hole 12 is driven to rotate during the rotation of the cleaning rod 506, and then the bubbles above the filter 3 can be broken up during the rotation of the crushing hole 12, so as to facilitate the bubbles to overflow the milk, effectively prevent the bubbles from affecting the normal passage of milk through the filter 3, and thus effectively improve the milk filtration efficiency.

[0053] like Figure 7 As shown, a plurality of the communication holes 706 are evenly arranged.

[0054] By adopting the above technical solution, by evenly opening a plurality of connecting holes 706, the connecting holes 706 are indirectly connected to the first water pipe 605, that is, the milk can flow indirectly to the first water pipe 605, so that the impact hole 602 can indirectly spray the milk, and further the bubble breaking effect of the impact hole 602 spraying the milk can be improved.

[0055] like Figure 2 , Figure 5 As shown, the bottom wall of the collecting box 801 is an inclined surface, and the bottom wall of the fixing rod 902 is a cone.

[0056] By adopting the above technical solution, by making the bottom wall of the collecting box 801 an inclined surface, it is possible to facilitate the impurities in the collecting box 801 to flow to the outside through the drain valve 907, and by making the bottom wall of the scraper rod a cone, the initial contact area between the fixed rod 902 and the socket 901 can be reduced during the process of inserting the fixed rod 902 into the socket 901, thereby facilitating the insertion of the fixed rod 902 into the socket 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, in the process of the cleaning rod 506 driving the filter net 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 direct 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 can drive the filter net 3 to move normally through the inclined block 508.

[0059] Instructions for use: When in use, first pour the milk into the filter cartridge 1 through the feed pipe 4, then the filter screen 3 can filter the impurities in the milk, and the user can take out the filtered milk through the discharge valve 2. At the same time, the user can start the motor 503, and then the motor 503 drives the crushing rod 505 to rotate through the rotating rod 504. During the rotation of the crushing rod 505, the bubbles in the milk can be broken up, and during the rotation of the rotating rod 504, the cleaning rod 506 can also be used to drive the filter screen 3 to shake up and down, and the bubbles in the milk can be cut; at the same time, the filter screen 3 is shaken up and down. During the movement, the telescopic tube 509 is driven to expand and contract back and forth, and the milk in the space between the outer wall of the telescopic tube 509 and the filter cartridge 1 is driven to flow to the connecting component 7 through the drain valve 604, and then flows to the impact groove 601 through the connecting component 7 and the first water pipe 605, and then impacts the bubbles in the milk through the impact hole 602 on the impact groove 601 to break up the bubbles; during the rotation of the cleaning rod 506, the impurities on the top wall of the filter screen 3 are driven to rotate, and then under the action of centrifugal force, the impurities move in the direction away from the rotating rod 504, and enter the collection box 801 through the collecting groove; when the impurities in the collection box 801 are When there is too much mass, the user can first pull the limiting rod 905 to make the limiting rod 905 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 to move downward. At the same time, the plug hole 901 is driven to rotate during the rotation of the blocking plate 802. After the plug hole 901 contacts the fixing rod 902, the second spring 903 drives the fixing rod 902 to be inserted into the plug hole 901 and fixes the blocking 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 together with the milk in the collection box 801. When the impurities are cleaned, the user can pull the fixing rod 902 upwards. At this time, the second spring 903 is stretched and has a tendency to recover. In the process of the fixing rod 902 moving upwards, 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 socket 901, the impurities in the collection box 801 can be cleaned while filtering the milk.

[0060] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
