Description

Technical Field

[0001] This utility model relates to the technical field of laver processing equipment, specifically a high-efficiency sorting device for removing impurities from laver. Background Technology

[0002] Weeds (such as seaweed and agar-agar) differ greatly in shape and color from laver. Their mixing can lead to uneven coloring and a rough texture in the finished laver, reducing the edible experience. The food and processing industries have clear standards for the purity of laver; laver with excessive weed content is classified as a low-grade product and cannot enter the high-end market.

[0003] Currently, when sorting laver into weeds, laver clumps together and are difficult to separate. Furthermore, when laver passes through grates of fixed width, blockages are easily caused, requiring frequent machine shutdowns for cleaning, resulting in less than 60% effective operating time for the equipment. During the sorting process, laver is severely damaged, with mechanical compression causing a laver fragmentation rate as high as 10%-15%, affecting the quality of the finished product.

[0004] Current sorting machines are only equipped with one sorting component, which cannot effectively screen out weeds. Moreover, once the weeds are sorted out, they cannot be transferred in time, causing secondary mixing with the seaweed to be sorted later. This results in low sorting efficiency and high sorting difficulty. Summary of the Invention

[0005] The purpose of this invention is to provide a highly efficient sorting device for removing impurities from seaweed, addressing the problems mentioned in the background section. This invention utilizes two sets of sorting components and a reciprocating oscillating sieve to clean the trough in real time, ensuring smooth sorting of seaweed along the trough and its descent into the discharge port. Larger weeds are completely separated and stored in a sorting box for batch cleaning from the top opening. This process significantly reduces trough wear while maintaining the integrity of the seaweed, resulting in a high-quality finished product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency sorting device for removing impurities from seaweed, comprising a sorting box, a top opening at the top of the sorting box, a sealed top cover on the top opening, a feed inlet on one side wall of the sorting box, a discharge outlet on the bottom plate of the sorting box, and a sorting assembly located directly opposite the discharge outlet inside the sorting box. The sorting assembly includes two sets of parallel grate cylinders, each grate cylinder being a semi-cylindrical thin shell, with the inner shell of the semi-cylindrical thin shell facing downwards and communicating with the discharge outlet. The grate cylinder has several equidistant grating teeth along the axis of the cylinder, and a grating groove is formed between two adjacent grating teeth to facilitate the sieving of seaweed. Above the grate cylinder is a row of several synchronously reciprocating grating blades, each grating blade passing through the grating groove and extending downwards into the inner shell space of the semi-cylindrical thin shell.

[0007] Several sieve blades are evenly spaced in each row. A swinging assembly is located above each blade to drive its reciprocating motion. The swinging assembly is mounted on both sides of the sorting box and connected to a drive mechanism located outside the sorting box. By using the reciprocating sieve blades, the troughs are cleaned in real time, ensuring that the seaweed is smoothly sorted along the troughs and falls into the discharge port. Weeds, due to their larger size, are completely sorted out and temporarily stored in the sorting box, exiting in batches from the top opening for further cleaning. During the sorting process, wear on the troughs is greatly reduced, while ensuring the integrity of the seaweed, resulting in high-quality finished seaweed.

[0008] As a further embodiment of this utility model, the swing assembly includes a blade holder, which includes an upper blade holder and a lower blade holder. A swing shaft is provided between the upper blade holder and the lower blade holder. One end of the swing shaft is set on the side wall of the sorting box, and the other end of the swing shaft is set on the opposite side wall through a bearing. The swing shaft is located on one side of the bearing and connected to the drive mechanism.

[0009] The lower blade holder has swing arm plates on both sides of its bottom surface. Between the two swing arm plates are an upper mounting shaft and a lower mounting shaft arranged sequentially. Each grate blade has a first shaft hole and a second shaft hole on its upper part. The upper mounting shaft is interference-fitted with the first shaft hole on each grate blade, and the lower mounting shaft is interference-fitted with the second shaft hole on each grate blade. A drive mechanism drives the swing assembly to reciprocate, resulting in high transmission efficiency and effectively driving the grate blades to continuously swing, cleaning the grate trough in real time, ensuring efficient sorting of the grate trough, and greatly improving the operating efficiency and timeliness of the equipment.

[0010] As a further embodiment of this invention, the drive mechanism includes a drive motor mounted on the side wall of the sorting box. A motor rocker arm is located at the output shaft end of the drive motor. A large connecting rod is hinged to the lower end of the motor rocker arm, and a small connecting rod is hinged to the free end of the large connecting rod. Both ends of the small connecting rod are hinged to large rocker arms. A large-end hinge hole is located on the upper part of the large rocker arm, and the large-end hinge hole is interference-fitted with the swing shaft. The drive mechanism, as a power source, transmits power to the swing assembly, saving energy and installation space while effectively utilizing the kinetic energy provided by the drive motor.

[0011] As a further embodiment of this utility model, the sorting box is also provided with a dispersing mechanism respectively arranged on both sides of the sorting component. One of the dispersing mechanisms is located at the feed inlet. The dispersing mechanism includes a guide plate for dispersing clumps of seaweed. A synchronous shaft is provided above the guide plate. Two suspension rings are provided between the guide plate and the synchronous shaft for fixed suspension. The two ends of the synchronous shaft are hinged to the inner wall of the sorting box.

[0012] Both the synchronous shaft and the top surface of the upper blade holder are equipped with connecting rod seats, and an intermediate connecting rod is provided between the two connecting seats. During the continuous oscillation process, the dispersing mechanism breaks up the clumps of laver. After dispersing, the weeds are initially separated from the laver, and the weeds wrapped in the clumps of laver are dispersed and sorted thoroughly, picking out each weed. Moreover, the dispersed laver is easier to pass through the trough for efficient sorting, and it will not cause the laver to be squeezed or torn.

[0013] As a further embodiment of this invention, the suspension ring is provided with a locking hole in the radial direction, and a thread is provided in the locking hole. A locking screw is threaded into the locking hole, and the head of the locking screw is pressed perpendicularly to the synchronous shaft. By locking the suspension ring with the locking screw, the guide plate swings synchronously in the circumferential direction with the suspension ring.

[0014] As a further embodiment of this invention, the discharge port includes two discharge branch pipes arranged side by side. The two discharge branch pipes are connected to a main discharge pipe via a tee, and a suction pump is connected to the main discharge pipe. When the suction pump operates, a negative pressure discharge space is created at the discharge port, allowing the sorted seaweed to be separated and transferred at high speed.

[0015] As a further embodiment of this utility model, the sealing top cover includes a flat cover surface, and side baffles are provided on both sides of the flat cover surface. The flat cover surface and the two side baffles form a U-shaped groove structure, and the opening of the U-shaped groove faces downward to fit and cover the top surface of the sorting box.

[0016] As a further embodiment of this utility model, sealing clips are provided on both sides of the sealing top cover along its length. The sealing clips include a card seat set on the top plate of the sorting box. A pressure arm is hinged to the end of the card seat near the sealing top cover, and a bracket is hinged to the end of the card seat away from the sealing top cover. A handle is hinged between the pressure arm and the free end of the bracket.

[0017] The sealed top cover has two symmetrical clamps on each side along its width. Each clamp includes a clamp base with a clamp pressure rod hinged to it. A retaining ring is hinged to the bent part of the clamp pressure rod. A locking block corresponding to the retaining ring is located on the outer wall of the sorting box. Through the cooperation of the sealing clips and clamps, the sealed top cover is completely sealed to the top opening. The sealed top cover can be opened and closed quickly and easily, ensuring a stable sorting space inside the sorting box and preventing seaweed from splashing outwards during the sorting process.

[0018] As a further improvement of this invention, a viewing window is provided in the center of the sealed top cover, and a viewing glass is installed inside the viewing window. The status inside the sorting box can be observed in real time through the viewing glass to determine whether weeds need to be cleared.

[0019] As a further embodiment of this invention, the bottom of the sorting box is provided with a drain outlet, which is located on the side of the feed inlet, and a drain pipe is provided at the drain outlet. The drain outlet facilitates the discharge of impurities generated after sorting operations and allows for regular cleaning of the internal structure of the sorting box.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This device includes a sorting box with a top opening and a sealed top cover. A feed inlet is located on one side wall of the sorting box, and a discharge outlet is located on the bottom plate. A sorting assembly is located inside the sorting box, directly opposite the discharge outlet. The sorting assembly includes two sets of parallel grate cylinders. Each grate cylinder is a semi-cylindrical thin shell, with the inner shell facing downwards and communicating with the discharge outlet. A drive mechanism drives reciprocating oscillating grate blades to clean the grate troughs in real time, ensuring that the seaweed is smoothly sorted along the grate troughs and falls into the discharge outlet. Weeds, due to their large size, are completely sorted out and temporarily stored in the sorting box, exiting in batches from the top opening for cleaning. During the sorting process, wear on the grate troughs is greatly reduced, while ensuring the integrity of the seaweed, resulting in high-quality finished seaweed.

[0021] The swing assembly is driven by a drive mechanism to swing back and forth, which has high transmission efficiency and effectively drives the grate knife to swing continuously, cleaning the grate in real time, ensuring efficient sorting of the grate, and greatly improving the operating efficiency and timeliness of the equipment.

[0022] The weeds are sorted twice by the sorting components, resulting in a cleaner finished seaweed product. This greatly improves sorting efficiency and yields high-quality finished seaweed.

[0023] The drive mechanism includes a drive motor mounted on the side wall of the sorting box. As a power source, the drive mechanism transmits power to the swing assembly, saving energy and installation space while effectively utilizing the kinetic energy provided by the drive motor.

[0024] The sorting box is also equipped with a dispersing mechanism on both sides of the sorting component. During the continuous oscillation process, the dispersing mechanism breaks up the clumps of laver. After dispersing, the weeds are initially separated from the laver, and the weeds wrapped in the clumps of laver are dispersed. The sorting is thorough, and each weed is separated. Moreover, the dispersed laver is easier to be efficiently sorted through the trough without causing the laver to be squeezed or torn.

[0025] The discharge manifold at the discharge port is connected to a suction pump. When the suction pump operates, it creates a negative pressure discharge space at the discharge port, allowing the sorted seaweed to be separated and transferred at high speed.

Detailed Implementation

[0039] 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 scope of protection of the present utility model.

[0040] Example 1

[0041] Please see the appendix Figure 1 -Appendix Figure 8 A high-efficiency sorting device for removing impurities from seaweed includes a sorting box 2 with a top opening and a sealing top cover 202. The sealing top cover includes a flat surface with side flanges on both sides, forming a U-shaped groove structure. The U-shaped groove opening faces downwards and fits to the top surface of the sorting box. A viewing window 221 is provided in the center of the sealing top cover, and a viewing glass is installed inside the window. The device monitors the operation of the sorting box in real time. When a certain amount of weeds are observed to have been sorted out, the device is paused, the sealing top cover is opened, and the weeds are removed from the top opening. After cleaning, the sealing top cover is closed, and the device resumes operation.

[0042] The sealing top cover is provided with sealing clips 4 on both sides along its length. The sealing clips include a card seat 401 set on the top plate of the sorting box. A pressure arm 402 is hinged to the end of the card seat near the sealing top cover, and a bracket 403 is hinged to the end of the card seat away from the sealing top cover. A handle 404 is hinged between the pressure arm and the free end of the bracket.

[0043] The sealing top cover has two clamps 3 symmetrically arranged on both sides of the width direction. The clamps are set on the sealing top cover. The clamps include a clamp seat 301, a clamp pressure rod 302 is hinged on the clamp seat, a retaining ring 303 is hinged at the bend of the clamp pressure rod, and a retaining block 304 corresponding to the retaining ring is provided on the outer wall of the sorting box.

[0044] Before the equipment is put into operation, the sealing top cover 202 is placed on the top surface and the position is adjusted. First, the pressure arm is rotated by rotating the handle through the bracket. The pressure arm presses against the sealing top cover and is pressed tightly in the length direction of the sealing top cover 202.

[0045] Next, rotate the clamping rod 302 to cause the retaining ring to flip downward. After the retaining ring 303 engages with the retaining block 304, rotate the clamping rod 302 in the opposite direction to tighten the retaining ring 303 vertically, so that the retaining ring 303 and the retaining block 304 generate a clamping force, which presses and positions the sealing top cover in the width direction.

[0046] The sorting box has a feed inlet 204 on one side wall, and a feed pipe 241 is provided at the feed inlet. The feed pipe is connected to a feeding device. The seaweed to be sorted is completely immersed in water, and the water in which the seaweed is suspended is injected into the sorting box through the feed inlet at a certain speed.

[0047] The bottom plate of the sorting box 2 is provided with a discharge port, which includes two discharge branch pipes 232 arranged side by side. The two discharge branch pipes are connected to a discharge main pipe 231 through a tee. The discharge main pipe is connected to a suction pump.

[0048] During the sorting process, the suction pump is constantly in operation. Activating the pump creates a negative pressure environment at the outlet and within the inner shell of the semi-cylindrical thin-shell structure. This continuously draws out the seaweed passing through the grates and discharges it along the main outlet pipe.

[0049] The sorting box is equipped with a sorting component located directly opposite the discharge port. The sorting component includes two sets of parallel grate cylinders 5. The grate cylinder is a semi-cylindrical thin shell. The inner shell of the semi-cylindrical thin shell is set downward and communicates with the discharge port. The grate cylinder is provided with a number of grating teeth at equal intervals along the axis of the cylinder. A grating groove 501 is provided between two adjacent grating teeth to form a grating groove for sieving laver. A row of several grating blades 504 that swing back and forth synchronously are provided above the grate cylinder. Each grating blade passes through the grating groove and extends downward and inward into the inner shell space of the semi-cylindrical thin shell.

[0050] During the sorting process, laver and weeds float in the water. Both laver and weeds swing rhythmically with the sieve blades. Laver is small in size and, under the negative pressure inside the semi-cylindrical shell, it quickly falls into the semi-cylindrical shell along the sieve 501 and is then discharged through the outlet.

[0051] The weeds are too large to pass through the grate 501 and remain suspended in the water inside the sorting box. When the weeds accumulate to a certain extent, they are cleaned up in time, and the sorting process continues after the cleaning is completed.

[0052] Several 504 sieve blades are equidistantly arranged in each row. The upper part of the sieve blade is equipped with a swinging component that drives the sieve blade to swing back and forth. During the sorting process, the sieve blade is always in a swinging state to clean the seaweed stuck in the sieve groove and maintain a smooth discharge gap.

[0053] The swing assembly is mounted on both sides of the sorting box body. The swing assembly includes a blade holder 503, which includes an upper blade holder 531 and a lower blade holder 533. A swing shaft 532 is provided between the upper blade holder and the lower blade holder. One end of the swing shaft 532 is mounted on the side wall of the sorting box, and the other end of the swing shaft is mounted on the opposite side wall through a bearing 502. The swing shaft is located on one side of the bearing 502 and is connected to the drive mechanism.

[0054] The lower blade holder has swing arm plates 534 on both sides of its bottom surface. Between the two swing arm plates are an upper mounting shaft and a lower mounting shaft 535 arranged sequentially. Each grate blade has a first shaft hole and a second shaft hole on its upper part. The upper mounting shaft is in series with the first shaft hole on each grate blade, and the lower mounting shaft is in series with the second shaft hole on each grate blade.

[0055] The swing assembly is connected to a drive mechanism located outside the sorting box. The drive mechanism includes a drive motor 105 mounted on the side wall of the sorting box. A motor rocker arm 101 is located at the output shaft end of the drive motor. A large connecting rod 102 is hinged to the lower end of the motor rocker arm. A small connecting rod 104 is hinged to the free end of the large connecting rod. Large rocker arms 103 are hinged to both ends of the small connecting rod. A large-end hinge hole is located on the upper part of the large rocker arm, and the large-end hinge hole is interference-fitted with the swing shaft.

[0056] During the sorting process, the drive motor 105 is started, the output shaft of the drive motor rotates, and the drive motor rocker arm 101 swings back and forth. The power is transmitted to the large rocker arm 103 through the large connecting rod 102 and the small connecting rod 104 in sequence, and finally drives the swing shaft to rotate. The rotation angle with the vertical direction is less than 45°.

[0057] The rotation of the swing shaft drives the blade holder and the swing arm plate to swing synchronously and reciprocally, so that the grate blades installed between the two swing arm plates 534 swing synchronously and reciprocally at the same time, and the swing arc formed by the blade blades just fills the grate groove 501.

[0058] Example 2

[0059] Please see the appendix Figure 5 -Appendix Figure 11Unlike Embodiment 1, the sorting box is also equipped with a dispersing mechanism 6 respectively located on both sides of the sorting component. One of the dispersing mechanisms is located at the feed inlet to disperse the seaweed clumps that enter and remain in the sorting box, so that the impurities in the seaweed clumps are separated from the seaweed and dispersed and float in the water.

[0060] The dispersing mechanism includes a guide plate 606 for dispersing clumps of seaweed, a synchronous shaft 601 above the guide plate, and two suspension rings 602 for fixed suspension between the guide plate and the synchronous shaft. Each suspension ring has a locking hole along its radial direction, with threads inside the locking hole. A locking screw 603 is threaded into the locking hole and its head is perpendicularly pressed against the synchronous shaft. The synchronous shaft is hinged at both ends to the inner wall of the sorting box.

[0061] Both the synchronous shaft and the top surface of the upper tool post are provided with connecting rod seats 604, and an intermediate connecting rod 605 is provided between the two connecting seats.

[0062] The rotation of the swing shaft transmits the motion to the synchronous shaft through the intermediate connecting rod. The synchronous shaft also rotates within a certain angle range. The rotation drives the guide plate to swing back and forth, patting and stirring the seaweed ball to break it up.

[0063] Two dispersing mechanisms completely disperse the seaweed in the sorting box, ensuring that the seaweed is fully separated from weeds.

[0064] Example 3

[0065] After the seaweed is sorted, there will be residual seaweed or weed residue, as well as deposited impurities, in the sorting box.

[0066] The bottom of the sorting box is provided with a drain outlet, which is located on the side of the feed inlet, and a drain pipe 201 is provided at the drain outlet.

[0067] Remove the sealed top cover 202 from the top opening, and flush clean water into the sorting box through the top opening. The flushing water will continuously wash away the impurities inside and discharge them through the drain outlet.

[0068] Clean the inside of the sorting box thoroughly before using it next time.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0070] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
