Description

Technical Field

[0001] This utility model relates to the field of pomegranate peel polyphenol extraction technology, and in particular to a crushing device for extracting pomegranate peel polyphenols. Background Technology

[0002] Crushing equipment is a key component in the extraction of polyphenols from pomegranate peel. Its main function is to crush the pomegranate peel to a suitable particle size to facilitate subsequent extraction operations. The working principle of crushing equipment is based on the material breaking under external force. Commonly used crushing equipment in the extraction of polyphenols from pomegranate peel, such as hammer crushers and roller crushers, utilize different mechanical forces to crush the material.

[0003] A hammer crusher mainly consists of a rotor, hammers, a screen plate, and a machine body. The rotor drives the hammers to rotate at high speed, and the hammers impact and shear the pomegranate peels entering the crushing chamber. When the pomegranate peels enter the crushing chamber, they are crushed into smaller particles by the impact and shearing action of the high-speed rotating hammers. At the same time, the screen plate plays a screening role, ensuring that the particle size of the crushed material meets the requirements.

[0004] However, when implementing existing technical solutions, screen hole clogging is a common problem for crusher screen plates. When the material contains a lot of impurities or fine powder, these impurities or fine powder may clog the screen holes, preventing the material from passing through the screen plate normally. Screen hole clogging will affect crushing efficiency and crushing quality. Summary of the Invention

[0005] The purpose of this invention is to provide a crushing device for extracting polyphenols from pomegranate peel. The vibration of the screen plate can effectively promote the movement and dispersion of materials on the screen, making it easier for fine particles to pass through the screen holes, thereby improving the screening efficiency. At the same time, the scraping action of the scraper can further clean the screen surface and ensure that the screen holes remain unobstructed, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for extracting polyphenols from pomegranate peel, comprising a crushing chamber, a discharge base fixedly installed at the bottom of the crushing chamber, a filter drive assembly provided at the connection between the discharge base and the crushing chamber, the filter drive assembly including an assembly groove formed on the upper surface of the discharge base, an assembly ring slidably installed inside the assembly groove, a sieve plate fixedly installed at the middle position of the assembly ring, and fixing plates fixedly installed at both ends of the assembly ring, with a transmission guide rod fixedly installed on the side of the fixing plate near the inner wall of the crushing chamber.

[0007] Preferably, the crushing box is provided with a crushing drive assembly, which includes a crushing motor fixedly installed on the top surface of the crushing box, and the power output end of the crushing motor is fixedly connected to a drive shaft through the top surface of the crushing box.

[0008] Preferably, a transmission rod is fixedly installed on the bottom outer wall of the transmission shaft, and a scraper is fixedly installed on the side wall of the transmission rod near the sieve plate.

[0009] Preferably, a crushing rope is fixedly installed on the side wall of the drive shaft opposite to the drive rod, and a crushing ball is fixedly installed at the other end of the crushing rope.

[0010] Preferably, an assembly drive rod is fixedly installed on the side wall of the drive shaft above the drive rod, and two crushing blades are horizontally fixedly installed on the outer wall of the assembly drive rod. The top end structure of the assembly drive rod is a hemispherical structure.

[0011] Preferably, the bottom of the crushing box has a cavity, and a spring is fixedly installed on the inner wall of the cavity. The other end of the spring is fixedly connected to a fixing plate.

[0012] Preferably, a limiting groove is formed on the bottom end face of the assembly ring, and a limiting guide is slidably installed inside the limiting groove, with the bottom end face of the limiting guide being fixedly connected to the assembly groove.

[0013] Preferably, the upper surface of the discharge base is a funnel-shaped structure, and a discharge valve pipe is fixedly installed inside the discharge base, with a filling hopper penetrating one side of the top of the crushing box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This invention reduces clogging of the sieve plate during filtration by vibrating the sieve plate, and the scraping action of the scraper further reduces clogging. The vibration of the sieve plate effectively promotes the movement and dispersion of materials on the sieve mesh, making it easier for fine particles to pass through the sieve holes, thereby improving screening efficiency. This helps to separate the desired polyphenolic substances more quickly and thoroughly during the extraction of pomegranate peel polyphenols. Vibrating sieving reduces clogging of the sieve holes because the vibration can loosen or dislodge particles stuck in the sieve holes due to the impact force. At the same time, the scraping action of the scraper further cleans the surface of the sieve mesh, ensuring that the sieve holes remain unobstructed, which is crucial for maintaining a continuous and stable extraction process.

[0016] 2. The crushing blades of this utility model pre-treat the pomegranate peel by cutting and crushing, thereby improving the convenience of crushing the pomegranate peel. The rotation of the crushing rope can swing the crushing ball, and the high-speed rotation of the crushing ball can crush the pomegranate peel by impact. At the same time, the rotating crushing rope can also crush the pomegranate peel in the middle part, thereby further improving the crushing effect of the pomegranate peel.

[0024] 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.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4 A crushing device for extracting polyphenols from pomegranate peel includes a crushing chamber 1. A discharge base 4 is fixedly installed at the bottom of the crushing chamber 1. A filter drive assembly 6 is provided at the connection between the discharge base 4 and the crushing chamber 1. The filter drive assembly 6 includes an assembly groove 603 formed on the upper surface of the discharge base 4. An assembly ring 602 is slidably installed inside the assembly groove 603. A sieve plate 601 is fixedly installed in the middle of the assembly ring 602. Fixing plates 605 are fixedly installed at both ends of the assembly ring 602. A transmission guide rod 607 is fixedly installed on the side of the fixing plate 605 near the inner wall of the crushing chamber 1. The top end of the transmission guide rod 607 has a hemispherical structure. The upper surface of the discharge base 4 has a funnel-shaped structure, and a discharge valve pipe 5 is fixedly installed inside the discharge base 4. A filling hopper 3 penetrates one side of the top of the crushing chamber 1.

[0027] The crushing box 1 is equipped with a crushing drive assembly 2. The crushing drive assembly 2 includes a crushing motor 201 fixedly installed on the top surface of the crushing box 1. The power output end of the crushing motor 201 passes through the top surface of the crushing box 1 and is fixedly connected to a drive shaft 202. A drive rod 205 is fixedly installed on the bottom outer wall of the drive shaft 202. A scraper 206 is fixedly installed on the side wall of the drive rod 205 near the screen plate 601. A crushing rope 207 is fixedly installed on the side wall of the drive shaft 202 away from the drive rod 205. A crushing ball 208 is fixedly installed at the other end of the crushing rope 207. An assembly drive rod 203 is fixedly installed on the side wall of the drive shaft 202 above the drive rod 205. Two crushing blades 204 are horizontally fixedly installed on the outer wall of the assembly drive rod 203. The top structure of the assembly drive rod 203 is a hemispherical structure.

[0028] By adopting the above technical solution, during use, the pomegranate peel to be crushed is added to the crushing box 1 through the filling hopper 3. When crushing is required, the crushing motor 201 is started. The operation of the crushing motor 201 drives the drive shaft 202 to rotate, which in turn drives the assembly drive rod 203 to rotate. The rotation of the assembly drive rod 203 allows the horizontally installed crushing blades 204 to cut and crush the pomegranate peel, thereby improving the convenience of crushing the pomegranate peel. When the drive shaft 202 rotates, it simultaneously drives the crushing rope 207 to rotate. The rotation of the crushing rope 207 causes the crushing ball 208 to rotate. Thus, the high-speed rotation of the crushing ball 208 impacts and crushes the pomegranate peel. At the same time, the rotating crushing rope 207 can also crush the pomegranate peel. The pomegranate peel in the middle part is crushed to further improve the crushing effect. During crushing, the rotation of the drive shaft 202 drives the drive rod 205 to rotate. The scraper 206 installed on the drive rod 205 can scrape the upper surface of the screen plate 601, which can avoid the problem of clogging of the screen plate 601 and improve the crushing and filtering effect of the pomegranate peel. The drive rod drives the crushing blade 204 to perform cutting and crushing pretreatment. At the same time, the rotation of the crushing rope 207 and the crushing ball 208 also increases the crushing effect. This multi-crushing mechanism can crush the pomegranate peel into smaller particles more quickly and effectively, thereby improving the extraction efficiency of polyphenols. The filtered and screened pomegranate peel material can fall into the discharge base 4, and the material can be discharged through the discharge valve pipe 5 at the bottom of the discharge base 4.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a cavity 604 is provided at the bottom of the crushing box 1. A spring 606 is fixedly installed on the inner wall of the cavity 604. The other end of the spring 606 is fixedly connected to a fixing plate 605. A limiting groove 608 is provided on the bottom surface of the assembly ring 602. A limiting guide 609 is slidably installed inside the limiting groove 608. The bottom surface of the limiting guide 609 is fixedly connected to the assembly groove 603. The limiting groove 608 and the limiting guide 609 can limit the movement of the assembly ring 602. The upper surface of the assembly ring 602 is in contact with the bottom surface of the inner wall of the crushing box 1 to prevent material from entering the cavity 604. The cavity 604 is used to house the spring 606, the fixing plate 605, and the transmission guide rod 607, thereby ensuring that the transmission guide rod 607 drives the fixing plate 605 to drive the assembly ring 602 and the screen plate 601 to operate stably.

[0030] By adopting the above technical solution, during use, when the assembly drive rod 203 rotates, the hemispherical structure at the top of the assembly drive rod 203 and the hemispherical structure at the top of the transmission guide rod 607 collide and press against each other, thereby pushing the transmission guide rod 607 to move. When the transmission guide rod 607 moves, it can drive the fixed plate 605 to move. The moving fixed plate 605 can compress the spring 606. When the spring 606 has no force acting on the fixed plate 605, its own elasticity recovers, thereby pushing the fixed plate 605 back to its initial position. At the same time, the fixed plate 605 can drive the assembly ring 602 to move. The assembly ring 602 can vibrate left and right in the assembly groove 603 through the limiting groove 608 and the limiting guide seat 609, thereby enabling the assembly ring 602 to move. The internally assembled sieve plate 601 vibrates, which reduces the risk of clogging during filtration. The scraping action of the scraper 206 further reduces clogging. The vibration of the sieve plate 601 effectively promotes the movement and dispersion of materials on the screen, making it easier for fine particles to pass through the sieve holes, thus improving screening efficiency. This helps to separate the desired polyphenols more quickly and thoroughly during pomegranate peel polyphenol extraction. Vibrating sieving reduces clogging because the vibration causes particles stuck in the sieve holes to loosen or fall off due to the impact force. Simultaneously, the scraping action of the scraper 206 further cleans the sieve surface, ensuring the sieve holes remain unobstructed, which is crucial for maintaining a continuous and stable extraction process.

[0031] Working principle: During use, the pomegranate peel to be crushed is added to the crushing box 1 through the feeding hopper 3. When crushing is required, the crushing motor 201 is started. The operation of the crushing motor 201 drives the transmission shaft 202 to rotate, which in turn drives the assembly drive rod 203 to rotate. The rotation of the assembly drive rod 203 allows the horizontally mounted crushing blades 204 to cut and crush the pomegranate peel, thereby improving the convenience of crushing the pomegranate peel. When the drive shaft 202 rotates, it synchronously drives the crushing rope 207 to rotate. The rotation of the crushing rope 207 causes the crushing ball 208 to rotate. The high-speed rotation of the crushing ball 208 impacts and crushes the pomegranate peel. Simultaneously, the rotating crushing rope 207 further crushes the pomegranate peel in the middle section, improving the crushing effect. During crushing, the rotation of the drive shaft 202 drives the drive rod 205 to rotate. The scraper 206 installed on the drive rod 205 scrapes the upper surface of the sieve plate 601. When the assembly drive rod 203 rotates, the hemispherical structure at the top of the assembly drive rod 203 contacts and presses against the hemispherical structure at the top of the drive guide rod 607, thus pushing the drive guide rod 607 to move. When the drive guide rod 607 moves, it can... The fixed plate 605 is moved, and the moving fixed plate 605 can compress the spring 606. When the spring 606 is not under any force, its own elasticity recovers, thus pushing the fixed plate 605 back to its initial position. At the same time, the fixed plate 605 can move the assembly ring 602. The assembly ring 602 can vibrate left and right in the assembly groove 603 through the limiting groove 608 and the limiting guide seat 609, so that the screen plate 601 assembled inside the assembly ring 602 can vibrate. When the screen plate 601 vibrates, it can reduce the problem of clogging during filtration. With the scraping action of the scraper 206, the problem of clogging of the screen plate 601 can be further reduced. The filtered and screened pomegranate peel material can fall into the discharge base 4, and the material can be discharged through the discharge valve pipe 5 at the bottom of the discharge base 4.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
