Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seafood processing technology, specifically a screening device for processing wakame seaweed. Background Technology
[0002] Wakame seaweed, also known as "sea mustard" or "skirt seaweed," is a type of seaweed with green, pinnately lobed leaves that are thinner than kelp. Its shape resembles a large, broken palm leaf fan or a skirt, hence its name. Wakame is a brown algae belonging to the Laminariaceae family and is considered a "sea vegetable." Rich in various trace elements and vitamins, it has extremely high nutritional value and is widely consumed and loved in daily life. During production and processing, dried wakame seaweed needs to be sieved to classify it into different sizes for easier subsequent processing and packaging.
[0003] However, traditional screening equipment often uses metal screens or fixed aperture structures, which has the following problems: wakame seaweed tends to clump together and clog the screen holes; rigid screening can easily damage the algae; multi-stage synchronous sorting cannot be achieved; and cleaning and maintenance are difficult. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides a screening device for processing wakame seaweed, which solves the problems of damage to the algae and low screening accuracy of traditional equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for processing wakame seaweed, characterized in that it includes a feeding system, a main frame, a screening mechanism, and a vibrator. The main frame adopts a double-layer rectangular structure, divided into upper and lower layers, which are connected by four vertical columns to form a stable box-type frame. The upper frame supports the screening mechanism and the feeding system, and the lower frame has a built-in collection trough and a vibrator installed at the bottom.
[0006] Optionally, the feeding system includes a conical inlet, a rotating shaft, and an adjusting plate. The upper part of the conical inlet is configured as a conical surface, and the lower part is configured as a cylindrical shape. The rotating shaft is installed inside the conical inlet cylinder, and a spiral plate is connected to the rotating shaft. The adjusting plate is installed at the conical surface of the conical inlet, and a pull rod is provided on the adjusting plate.
[0007] Optionally, the main frame includes a fixing ring, a first box, and a second box. The fixing ring, the first box, and the second box are connected in order from top to bottom. The fixing ring is connected to the first box through a baffle. The conical inlet cylinder is fixed at the center ring of the fixing ring. A collection groove is provided inside the second box, which is divided into three parts: left, middle, and right.
[0008] Optionally, the screening mechanism includes a support frame, a first screen, a second screen, a third screen, and vibrating balls. The first screen, the second screen, and the third screen are arranged in a first housing in a top-to-bottom order, with the height of the first screen lower than the height of the baffle. The screen has multiple filter holes, and springs are provided on both sides of the screen, embedded in the inner wall of the first housing. The first housing has a first slide rail and a second slide rail on both sides. The first slide rail is connected to the first screen at the beginning and leads to the collection trough at the end. The second slide rail is connected to the second screen at the beginning and leads to the collection trough at the end. A funnel is installed at the bottom of the third screen, and the outlet of the funnel leads to the collection trough. Multiple thin ropes are connected to the support frame, and multiple vibrating balls are installed on the thin ropes. All vibrating balls abut against the bottom of the screen.
[0009] Optionally, the vibrator is provided with a base at its bottom, and a plurality of shock-absorbing pads are provided at the bottom of the base.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] In this invention, the screen can be made of nylon, which has a smooth surface and low breakage rate. It has three layers of screen, with the filter holes of each layer decreasing in size as the height decreases. Each layer of screen is spring-embedded on both sides of the main frame. When vibrating, the screen bounces up, down, left, and right. Vibrating balls are set under each layer of screen. When the machine vibrates, the vibrating balls automatically and continuously tap the back of the screen, allowing the wakame seaweed to be filtered in stages as it moves down through the filter holes. The impact force is buffered by the flexible material and then transmitted to the filter hole area, which can eject the wakame seaweed debris stuck in the holes. Traditional metal screens are too hard and can easily scratch the surface of the wakame seaweed, resulting in nutrient loss and poor appearance. Rigid vibration can also cause the algae to break during the screening process, resulting in waste of debris. In this invention, the combination of nylon screen, spring elastic support, and self-cleaning vibrating balls can reduce the breakage rate of wakame seaweed and achieve precise filtration and self-cleaning anti-clogging functions.
[0012] In this invention, the screened vegetables vibrate left and right due to the elasticity of the spring, and can slide to the left and right parts of the collection trough along the first and second slides. Meanwhile, the vegetables in the third sieve can slide to the center of the collection trough along the funnel, so that vegetables of different sizes can enter different areas, thereby completing the collection during the vibration process and greatly improving the screening efficiency.
[0013] The feeding system of this invention is equipped with an adjustment plate. Users can push and pull the adjustment plate with a lever to control the feeding speed. The rotating shaft drives the spiral plate, which can effectively break up the clumps of vegetables, thereby improving the efficiency of the screening process. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 7 As shown, this utility model provides a screening device for processing wakame seaweed, characterized in that it includes a feeding system 1, a main frame 2, a screening mechanism 3 and a vibrator 4. The main frame 2 adopts a double-layer rectangular structure, which is divided into upper and lower layers and connected by four vertical columns 15 to form a stable box frame. The upper frame supports the screening mechanism 3 and the feeding system 1, and the lower frame has a built-in collection trough 5 and a vibrator 4 installed at the bottom.
[0025] The feeding system 1 includes a conical inlet 6, a rotating shaft 7, and an adjusting plate 8. The upper part of the conical inlet 6 is set as a conical surface, and the lower part is set as a cylindrical shape. The rotating shaft 7 is installed inside the cylindrical part of the conical inlet 6, and a spiral plate 9 is connected to the rotating shaft 7. The adjusting plate 8 is installed at the conical surface of the conical inlet 6, and a pull rod 10 is provided on the adjusting plate 8.
[0026] The above solution is adopted: The feeding system 1 of this utility model is equipped with an adjustment plate 8. The user can push and pull the adjustment plate 8 through the pull rod 10 to control the feeding speed. The rotating shaft 7 drives the spiral plate 9, which can effectively break up the clumps of vegetables, thereby improving the efficiency of the screening process.
[0027] The main frame 2 includes a fixing ring 11, a first box 12, and a second box 13. The fixing ring 11, the first box 12, and the second box 13 are connected in order from top to bottom. The fixing ring 11 is connected to the first box 12 through a baffle 14. The conical inlet 6 is fixed at the center of the fixing ring 11 at the cylindrical part. The second box 13 is provided with a collection groove 5, which is divided into three parts: left, middle, and right.
[0028] Using the above scheme: In this utility model, the screened vegetables can slide to the left and right parts of the collection trough 5 along the first slide 23 and the second slide 24 due to the elastic vibration of the spring 22, while the vegetables in the third screen 19 can slide to the center of the collection trough 5 along the funnel 25, so that vegetables of different sizes enter different areas, thereby completing the collection during the vibration process and greatly improving the screening efficiency.
[0029] The screening mechanism 3 includes a support 16, a first screen 17, a second screen 18, a third screen 19, and vibrating balls 20. The first screen 17, the second screen 18, and the third screen 19 are arranged in the first housing 12 in a top-to-bottom order, and the height of the first screen 17 is lower than the height of the baffle 14. The screen is provided with multiple filter holes 21, and springs 22 are provided on both sides of the screen. The springs 22 are embedded in the inner wall of the first housing 12. The first slide 23 and the second slide 24 are provided on both sides of the first housing 12. The first slide 23 is connected to the first screen 17 at the head and leads to the collection trough 5 at the tail. The second slide 24 is connected to the second screen 18 at the head and leads to the collection trough 5 at the tail. A funnel 25 is installed at the bottom of the third screen 19, and the outlet of the funnel 25 leads to the collection trough 5. Multiple thin ropes 26 are connected to the support 16, and multiple vibrating balls 20 are installed on the thin ropes 26. All vibrating balls 20 are in contact with the bottom of the screen.
[0030] The above-mentioned solution is as follows: In this utility model, the screen can be made of nylon, which has a smooth surface and low breakage rate. It has three layers of screen, and the filter holes 21 of each layer become smaller as the height decreases. Each layer of screen is inlaid on the main frame 2 with springs 22 on both sides. When vibrating, the screen bounces up, down, left and right. Each layer of screen is equipped with a vibrating ball 20. When the machine vibrates, the vibrating ball 20 automatically and continuously hits the back of the screen, so that the wakame can be filtered in stages as it goes down through the filter holes 21. The impact force is buffered by the flexible material and transmitted to the filter hole 21 area, which can pop out the wakame debris stuck in the holes. Traditional metal screens are too hard and easily scratch the surface of the wakame, resulting in nutrient loss and poor appearance. Rigid vibration can also easily cause the algae to break during the screening process, resulting in waste of debris. In this utility model, the nylon screen + spring 22 elastic support + vibrating ball 20 self-cleaning can reduce the breakage rate of wakame and achieve precise filtration and self-cleaning anti-clogging function.
[0031] The vibrator 4 has a base 27 at its bottom, and multiple shock-absorbing pads 28 are provided at the bottom of the base 27.
[0032] The working principle and usage process of this utility model: After the user introduces the vegetables into the feeding system, the adjusting plate 8 can be pushed or pulled by the pull rod 10 to control the feeding speed. The rotating shaft 7 drives the spiral plate 9, which can effectively break up clumps of vegetables, thus improving the efficiency of the screening process. The screening mechanism 3 is equipped with three layers of screens, and the filter holes 21 of each layer become smaller as the height decreases. Each layer of screen is embedded in the main frame 2 with springs 22 on both sides. When vibrating, the screen bounces up, down, left, and right. Vibrating balls 20 are set below each layer of screen. When the machine vibrates, the vibrating balls 20 automatically and continuously tap the back of the screen, so that the seaweed can be graded and filtered downwards through the filter holes 21. The impact force is buffered by the flexible material and transmitted to the filter hole 21 area, which can remove the seaweed stuck in the holes. Wakame seaweed fragments are ejected. Traditional metal screens are too hard and easily scratch the surface of the wakame seaweed, leading to nutrient loss and poor appearance. Furthermore, rigid vibration can easily cause the seaweed to break during the screening process, resulting in waste of fragments. In this invention, the nylon screen + spring 22 elastic support + vibrating ball 20 self-cleaning can reduce the breakage rate of wakame seaweed and achieve precise filtration and self-cleaning anti-clogging functions. After screening, the seaweed can slide to the left and right parts of the collection tank 5 along the first slide 23 and the second slide 24 due to the elastic left and right vibration of the spring 22. The seaweed in the third screen 19 can slide to the center of the collection tank 5 along the funnel 25, so that seaweed of different sizes can enter different areas, thus completing the collection during the vibration process and greatly improving the screening efficiency.
