During the pretreatment process, some filter units have poor filtering effects and fail to effectively remove impurities, sediments or suspended matter in the salted duck egg white, causing these impurities to enter the ultrafiltration tube. Impurities or particulate matter in the salted duck egg white can easily cause blockage and contamination of the ultrafiltration membrane, affecting the normal operation and desalination effect of the ultrafiltration membrane, resulting in unsatisfactory product quality. In addition, some filter units are inconvenient to clean and maintain, which will also reduce the filtering efficiency of the salted duck egg white and affect subsequent processing.

[0003] Chinese patent authorization announcement number CN222151562U discloses a salted duck egg white membrane ultrafiltration desalination device, which processes salted duck egg white through filtering, dilution stirring, ultrasonic and ultrafiltration steps.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 6 as well as Fig.11 As shown: A salted duck egg white desalination membrane filtration device, comprising a barrel 1, the side wall of the barrel 1 is provided with at least two feed inlets, a feed bin 2 is provided at the feed inlet, a branch pipe 16 for conveying salted duck egg white is provided on the feed bin 2, and the ends of the plurality of branch pipes 16 are connected to a main pipe 15; an installation slot 17 is provided on the outer wall of the feed bin 2, a plug plate 21 is inserted in the installation slot 17, a placement groove 22 is provided on the plug plate 21, and a filter screen 3 is placed in the placement groove 22; a circular downwardly extending groove is provided at the edge of the filter screen 3 A dirt tank 31; a rotating block 32 is rotatably connected to the center of the filter screen 3, and a first scraper 33 is provided on the rotating block 32, which can scrape large-volume impurities accumulated on the upper surface of the filter screen 3 into the dirt tank 31; the side wall of the barrel 1 is also provided with a dilution tube 11 for conveying water to the inside of the barrel 1; a stirring rod 14 for stirring materials is provided in the barrel 1, and a discharge pipe 12 is provided at the bottom of the barrel 1, and the other end of the discharge pipe 12 away from the barrel 1 is connected to an ultrafiltration tube for ultrafiltration of the filtered egg white; an ultrasonic element 13 is also provided on the barrel 1.

[0033] The salted duck egg whites are transported to each feed bin 2 through the branch pipe 16. In the feed bin 2, the egg whites first pass through the filter screen 3 in the placement groove 22. The edge of the filter screen 3 is provided with a circular dirt collecting groove 31 extending downward to effectively collect the intercepted large-volume impurities to avoid clogging.

[0034] In order to reduce the replacement frequency of the filter 3, a rotating block 32 is rotatably connected at the center of the filter 3, and a first scraper 33 is installed on the rotating block 32. When the rotating block 32 is driven to rotate, the first scraper 33 will scrape the large volume impurities accumulated on the upper surface of the filter 3 into the dirt tank 31, thereby reducing the replacement frequency of the filter 3 and extending the working time of a single filter 3.

[0035] At the same time, the dilution tube 11 arranged on the side wall of the barrel 1 can transport water to the inside of the barrel 1 to dilute the salted duck egg white to reduce its salt concentration in preparation for subsequent ultrafiltration treatment. The diluted egg white is fully mixed in the barrel 1 through the stirring action of the stirring rod 14 to ensure uniform distribution of salt and improve desalination efficiency.

[0036] The diluted and stirred egg white then flows into the ultrafiltration tube through the discharge pipe 12 at the bottom of the barrel 1. As the core component of the desalination membrane filtration device, the ultrafiltration tube can utilize the selective permeability of the semipermeable membrane to discharge small molecules (such as water, some sugars, etc.) and salt in the egg white through the membrane layer, while macromolecules such as proteins are retained on one side of the membrane, thereby achieving desalination of the egg white.

[0037] In addition, an ultrasonic element 13 is also provided in the barrel 1. The ultrasonic vibration can enhance the fluidity of the egg white and reduce its adhesion to the inner wall of the barrel 1 and the stirring rod 14. It also helps to destroy the tiny particle aggregates in the egg white and improve the filtering effect and desalination rate.

[0038] Reference Figure 6 As shown in FIG. 3 , the aperture of the circular dirt receiving groove 31 is smaller than the aperture of the filter screen 3 .

[0039] When the salted duck egg white passes through the filter 3, the filter 3 will intercept the large volume of impurities and particles in the egg white, ensuring that only the relatively pure egg white continues to flow. However, the intercepted impurities will gradually accumulate on the filter 3, forming a layer of obstruction, affecting the filtering efficiency and effect.

[0040] When the first scraper 33 on the rotating block 32 rotates and scrapes the surface of the filter screen 3, the accumulated impurities will be effectively scraped into the dirt receiving tank 31, thereby achieving effective collection of the impurities.

[0041] Reference Figure 1-Figure 6 and Fig.11 As shown: the shape of the filter screen 3 is a circular structure, and the length of the first scraper 33 is equal to the radius of the filter screen 3; a partition plate 9 is arranged in the feed bin 2, and the partition plate 9 is arranged directly above the plug plate 21, and a through hole that matches the filter screen 3 is formed on the partition plate 9, and the upper surface of the partition plate 9 is formed with a slope 10 extending toward the center of the filter screen 3.

[0042] The slope 10 helps to guide the egg white to flow more smoothly to the center of the filter screen 3, avoiding accumulation and retention on the side wall of the feed bin 2. At the same time, the existence of the slope 10 also makes it easier for the impurities intercepted by the filter screen 3 to be scraped into the circular dirt collecting tank 31 by the first scraper 33, because the impurities will naturally converge to the center of the filter screen 3 under the guidance of the slope.

[0043] The first scraper 33 rotates on the upper surface of the filter screen 3 to push the accumulated impurities toward the dirt receiving tank 31. Since the length of the first scraper 33 is equal to the radius of the filter screen 3, it can ensure that the entire surface of the filter screen 3 is thoroughly cleaned.

[0044] Reference Figure 1-Figure 11 As shown: a rotating shaft 4 is vertically arranged in the feed bin 2, one end of the rotating shaft 4 is keyed to the top of the rotating block 32, and the other end of the rotating shaft 4 can rotate to pass through the top of the feed bin 2 and extend upward; a servo motor 41 is arranged at the top center of the barrel 1, and a connecting shaft 48 is arranged at the output end of the servo motor 41, which passes through the top of the barrel 1 and extends into the inside of the barrel 1, and the connecting shaft 48 is fixedly connected to the stirring rod 14; the connecting shaft 48 and the rotating shaft 4 are connected through a synchronous transmission mechanism 6.

[0045] The output end of the servo motor 41 is connected to a connecting shaft 48 that passes through the top of the barrel 1 and extends into the inside of the barrel 1. The connecting shaft 48 is fixedly connected to the stirring rod 14, so when the connecting shaft 48 rotates, the stirring rod 14 will also rotate to stir the egg white in the barrel 1.

[0046] A synchronous transmission mechanism 6 is provided between the rotating shaft 4 and the connecting shaft 48 , through which the power of the servo motor 41 is efficiently transmitted to the rotating shaft 4 and also to the connecting shaft 48 , thereby achieving synchronous driving of the stirring rod 14 and the rotating block 32 .

[0047] When the servo motor 41 is started, its output shaft drives the connecting shaft 48 to rotate, and the connecting shaft 48 in turn drives the stirring rod 14 to rotate, stirring the egg white in the barrel 1. At the same time, through the synchronous transmission mechanism 6, the rotating shaft 4 also rotates, and drives the rotating block 32 key-connected thereto to rotate together, and the first scraper 33 and other components on the rotating block 32 also rotate accordingly, scraping and cleaning the filter screen 3, and pushing impurities into the dirt receiving tank 31.

[0048] Reference Figure 7-Figure 11As shown: a disc 43 is provided at the top of the rotating shaft 4, and a cross limit block 42 is provided at the bottom of the disc 43; a fixed sleeve 44 is provided at the top of the feeding bin 2, and a driven wheel 45 is rotatably provided outside the fixed sleeve 44, and a cross limit through-hole 47 adapted to the cross limit block 42 is opened on the driven wheel 45, and two blocks 46 capable of clamping the disc 43 are provided on the top of the driven wheel 45, and the two blocks 46 are arranged in a mirror image.

[0049] A driven wheel 45 is rotatably arranged outside the fixing sleeve 44 . The driven wheel 45 is provided with a cross-limiting through hole 47 whose shape and size match the cross-limiting block 42 , so that the cross-limiting block 42 can smoothly pass through the driven wheel 45 and form a stable connection with the driven wheel 45 .

[0050] Since the driven wheel 45 can rotate freely relative to the fixing sleeve 44 , when the disc 43 is clamped, the rotating shaft 4 can still continue to rotate.

[0051] Reference Figure 1-Figure 10 As shown in the figure: the top of the driven wheel 45 is provided with a moving mechanism 5 for driving the two blocks 46 to move toward or away from each other, and the moving mechanism 5 includes a first moving box 51 and a second moving box 56; the number of the first moving boxes 51 is the same as the number of the blocks 46 and they are arranged on the top of the driven wheel 45 in a one-to-one correspondence, the bottom of the blocks 46 can be movably arranged in the first moving box 51, and the inside of the first moving box 51 is provided with a horizontally arranged guide rod 52, the bottom of the blocks 46 is provided with a through hole that can move along the axis of the guide rod 52, and the outer sleeve of the guide rod 52 is provided with a return spring, The two ends of the positioning spring are respectively set to abut one end of the interior of the first moving box 51 and the side wall of the block 46; the number of the second moving boxes 56 is the same as the number of the first moving boxes 51, the second moving boxes 56 are set at the top of the driven wheel 45 and are located between the two first moving boxes 51, and the interior of the second moving box 56 is provided with a pushing rod 57 that can move toward the axial direction of the driven wheel 45, and the two sides of the pushing rod 57 are respectively hinged with rotating rods 55, and the two sides of the block 46 are respectively provided with moving blocks 54, and one end of the two rotating rods 55 is respectively hinged with the moving blocks 54 on the corresponding two blocks 46.

[0052] The clamping block 46 can move along the first movable box 51 at the top of the driven wheel 45 to achieve engagement or disengagement with the disc 43. In order to ensure the stable movement of the clamping block 46, a guide rod 52 is provided in the first movable box 51, and a return spring 53 is sleeved on the guide rod 52. The return spring 53 provides an elastic force for the clamping block 46 to move toward the disc 43, ensuring that the clamping block 46 can be tightly engaged with the disc 43 when there is no external force.

[0053] The guide rod 52 is inserted into the through hole, thereby limiting the block 46 to move only along the direction of the guide rod 52 .

[0054] The push rod 57 is slidably connected in the second moving box 56 . When the block 46 needs to be separated from the disc 43 , the push rod 57 can be pushed along the second moving box 56 toward the disc 43 .

[0055] The pushing rod 57 and the moving block 54 are rotatably connected via the rotating rod 55. When the pushing rod 57 moves, the pushing rod 57 drives the moving block 54 to move in the through groove of the first moving box 51 via the rotating rod 55. Since the moving block 54 is connected to the blocking block 46, the movement of the moving block 54 will drive the blocking block 46 to move along the first moving box 51 in a direction away from the disc 43, thereby realizing the separation of the blocking block 46 from the disc 43.

[0056] Reference Figure 1-Figure 11 As shown: the synchronous transmission mechanism 6 includes a driving gear 61 and a driven gear 63; the driving gear 61 is arranged on the connecting shaft 48, the number of the driven gears 63 is the same as the number of the driven wheels 45 and are arranged one by one on the side of the driving gear 61, and the driving gear 61 is meshed with the driven gear 63; a rotating rod 62 is arranged at the center of the driven gear 63, the rotating rod 62 is fixedly arranged on the top of the barrel 1, the driven gear is rotatably connected to the rotating rod 62, and a driving wheel 64 is fixedly connected to the top of the driven gear 63; the driving wheel 64 and the driven wheel 45 are connected through a synchronous belt transmission.

[0057] When the connecting shaft 48 rotates, the driving gear 61 rotates accordingly, and the driven gear 63 meshes with the driving gear 61 . When the driving gear 61 rotates, it can drive all the driven gears 63 to rotate synchronously.

[0058] A rotating rod 62 is provided at the center of each driven gear 63, and the rotating rod 62 is fixed to the top of the barrel 1. A driving wheel 64 is fixedly connected to the top of the driven gear 63. The driving wheel 64 and the driven wheel 45 are connected through a synchronous belt. When the driven gear 63 rotates, it will drive the driving wheel 64 above it to rotate synchronously, and then drive the driven wheel 45 to rotate through the synchronous belt.

[0059] Reference Figure 1 and Figure 2 As shown: the branch pipe 16 is provided with a solenoid valve.

[0060] The operator can precisely control the flow of the fluid in the branch pipe 16 by controlling the power-on and power-off states of the solenoid valve.

[0061] Reference Figure 1-Figure 10 As shown: the stirring rod 14 is provided with a second scraper 7 which fits the inside of the barrel 1 .

[0062] When the stirring rod 14 starts to rotate, the second scraper 7 will move with the stirring rod 14 and scrape along the inner wall of the barrel 1. During this process, the second scraper 7 can effectively scrape off the egg white solution or other residues attached to the inner wall of the barrel 1 to ensure that they can be fully mixed or filtered.

[0063] Reference Figure 1-Figure 11 As shown: a limiting mechanism 8 is provided at the installation slot 17 outside the feed bin 2, and the limiting mechanism 8 includes a limiting sleeve 81 and a limiting insert block 82; the limiting sleeve 81 is provided on the outside of the feed bin 2, and the limiting insert block 82 is inserted in the limiting sleeve 81, and when the insert plate 21 is inserted in the feed bin 2, the inner side of the limiting insert block 82 abuts against the outer side of the insert plate 21.

[0064] When the limiting plug block 82 is fully inserted into the limiting sleeve 81 , the position of the plug board 21 can be effectively limited to prevent the plug board 21 from accidentally moving or falling off in the installation slot 17 .

[0065] The salted duck egg white is introduced into the feed bin 2 of the device. Due to the slope 10 of the side wall of the feed bin 2 extending toward the center of the filter screen 3, the egg white can flow smoothly to the filter screen 3. The filter screen 3 intercepts large-volume impurities and particulate matter in the egg white, and only allows relatively pure egg white to continue to flow for subsequent desalination treatment. The intercepted impurities gradually accumulate on the filter screen 3, forming a layer of obstruction. At this time, the servo motor 41 is started, and its output shaft drives the connecting shaft 48 to rotate, and the connecting shaft 48 then drives the stirring rod 14 to rotate in the barrel 1 to stir the egg white. At the same time, through the synchronous transmission mechanism 6, the rotating shaft 4 also rotates therewith, and drives the rotating block 32 keyed thereto to rotate together. The first scraper 33 on the rotating block 32 moves on the upper surface of the filter screen 3 with the rotation of the rotating shaft 4, pushing the accumulated impurities to the dirt receiving tank 31. Since the aperture of the dirt receiving tank 31 is smaller than the aperture of the filter screen 3, the impurities are effectively collected in the dirt receiving tank 31, avoiding entering the barrel 1 again.

[0066] In addition, when the filter 3 needs to be cleaned or replaced, the moving mechanism 5 can be operated to disengage the clamping block 46 from the disc 43, thereby releasing the fixation of the rotating shaft 4. At this time, the rotating block 32 and the filter 3 can be easily taken out for cleaning or replacement.

[0067] During the desalination process, the operator can precisely control the flow of the fluid in the branch pipe 16 by controlling the power-on and power-off states of the solenoid valve, thereby achieving precise control of the desalination process.

[0068] At the same time, the second scraper 7 on the stirring rod 14 scrapes along the inner wall of the barrel 1 as the stirring rod 14 rotates, scraping off the egg white solution or other residues attached to the inner wall of the barrel 1 to ensure that they can be fully mixed or filtered.

[0069] Finally, when the insert plate 21 is inserted into the installation slot 17 and fixed by the limiting mechanism 8, the entire filtering device forms a closed system, ensuring the stability and safety of the egg white during the filtration and desalination process. The design of the limiting mechanism 8 prevents the insert plate 21 from accidentally moving or falling off in the installation slot 17, further improving the stability and reliability of the device.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
