Description

Technical Field

[0001] This utility model relates to the field of glycerol preparation technology, specifically to a continuous glycerol refining and impurity removal device. Background Technology

[0002] Glycerin, also known as glycerol, is an organic compound with the chemical formula C3H8O3. It is a simple polyol compound. In the extraction and refining of glycerin, crude glycerin needs to be pretreated to filter out large particles, thereby obtaining high-quality glycerin.

[0003] A search revealed a crude glycerol refining device with application number 202420586638.7. This device uses a motor-driven fan to create a swirling flow of glycerol. Centrifugal force forces the less dense glycerol through the filter holes, while larger particles fall to the bottom of the separation tank, thus separating glycerol of different densities and improving filtration efficiency. Although it can separate large impurities in glycerol, the gap between the fan and the separation tank results in poor agitation of the glycerol, especially at the bottom of the separation tank. Furthermore, the filter holes require time to filter the glycerol; most of the glycerol, under gravity, gradually follows the impurities to the bottom of the separation tank and is discharged with them, requiring recollection and filtration, severely impacting production efficiency. Similarly, smaller or lighter impurities are also affected by centrifugal force. Unable to pass through the filter holes, they adhere to the inner wall of the separation tank, clogging the filter holes and affecting glycerol throughput, thus impacting the filtration efficiency of crude glycerol. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a continuous glycerol refining and impurity removal device to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous glycerol refining and impurity removal device, comprising a base and a separation cylinder. A servo motor is provided at the top of the separation cylinder, and a rotating shaft is connected to the output end of the servo motor. A collision rod is connected to the bottom end of the rotating shaft, and a scraper is connected to the outer surface of the rotating shaft. A first magnet is installed at the bottom of the scraper. A filter cylinder is placed inside the separation cylinder through a support ring. A slag outlet is opened at the bottom of the filter cylinder, and a baffle is connected inside the slag outlet. A second magnet is installed on one side of the top of the baffle. Two mounting plates are connected to one side of the bottom of the filter cylinder. A guide plate is connected between the two mounting plates through a rotating rod. A collision block and a spring are connected to the bottom of the guide plate, and one end of the spring is connected to the mounting plate.

[0006] Furthermore, a feed pipe is installed on the upper side of one side of the separating cylinder, and a discharge pipe is installed on the other side of the separating cylinder, with a valve installed at one end of both the feed pipe and the discharge pipe.

[0007] By adopting the above technical solution, the staff opens the valve (not shown in the figure), and the crude glycerin enters the filter cylinder through the feed pipe for filtration. Driven by the output of the servo motor, the rotating shaft drives the scraper to rotate and agitate the glycerin, causing the glycerin to swirl and circulate inside the filter cylinder. Through the agitation of the scraper, the filtration speed of the glycerin through the filter holes on the filter cylinder is accelerated. The filtered glycerin is then transported to the next process through the discharge pipe for subsequent processing.

[0008] Furthermore, the scraper comes into contact with the inner wall of the filter cartridge.

[0009] By adopting the above technical solution, after crude glycerol enters the filter cylinder, it is rotated inside the filter cylinder by the scraper. The centrifugal force accelerates the speed at which the glycerol passes through the filter holes on the filter cylinder, thereby improving the filtration efficiency. At the same time, the side wall of the scraper contacts the inner wall of the filter cylinder, scraping away the impurities adsorbed on the filter cylinder and preventing impurities from adsorbing on the inner wall of the filter cylinder and causing the filter holes to become clogged.

[0010] Furthermore, a first groove is provided at the bottom of the filter cylinder, and the baffle is slidably connected to the filter cylinder through the first groove.

[0011] By adopting the above technical solution, when it is necessary to clean the impurities inside the filter cylinder, the operator closes the feed pipe valve and starts the servo motor to reverse. The output end of the servo motor drives the rotating shaft to rotate, thereby driving the scraper to rotate in the opposite direction. Under the drive of the scraper, the first magnet and the second magnet are magnetically attracted. The first magnet drives the second magnet to move along the first chute, thereby driving the baffle to move and remove the obstruction to the slag outlet. At the same time, the scraper scrapes the impurities into the slag outlet and away from the filter cylinder. There is no need for manual cleaning of the impurities inside the filter cylinder, thereby speeding up production efficiency.

[0012] Furthermore, both the first magnet and the second magnet are neodymium magnets.

[0013] By adopting the above technical solution, neodymium magnets have strong magnetic force, high mechanical strength, are not easy to break, and have a long service life. Through the magnetic attraction between the first magnet and the second magnet, when the servo motor rotates forward, the first magnet drives the baffle to move to one side of the first chute under the limit of the first chute, thus closing the slag outlet. When the servo motor rotates in reverse, the second magnet drives the baffle to move to the other side of the first chute, thus opening the slag outlet. Therefore, it is not necessary to stop the device to clean the impurities, so as to realize continuous production and improve production efficiency.

[0014] Furthermore, the collision block has an inverted triangular cross-section, and the collision rod is in contact with the collision block.

[0015] By adopting the above technical solution, the rotating shaft drives the collision rod to rotate under the output of the servo motor. During the rotation of the collision rod, it intermittently collides with the collision block. In conjunction with the spring, the guide plate slides up and down on one side to generate vibration. The vibration increases the movement speed of impurities on the guide plate, thereby quickly discharging them from the separation cylinder. The triangular design ensures that the collision rod can quickly detach after contacting the collision block when rotating forward or backward.

[0016] Furthermore, the rotating rod is provided in two sets, and one set of rotating rods is rotatably connected to the mounting plate.

[0017] By adopting the above technical solution, the guide plate is driven by the rotating rod to rotate within a small range between the two mounting plates, and in cooperation with the spring, when the collision rod contacts the collision block, the guide plate vibrates. Through the vibration generated and guided by the guide plate, impurities are quickly discharged from the separation cylinder.

[0018] Furthermore, a second sliding groove is provided in the mounting plate, and another rotating rod is slidably connected to the mounting plate through the second sliding groove.

[0019] By adopting the above technical solution, the guide plate is limited by the second slide groove and another rotating rod, thereby controlling the rotation amplitude of the guide plate and keeping the rotation amplitude within a certain range.

[0020] Furthermore, a rubber layer is provided at the bottom of the baffle.

[0021] By adopting the above technical solution, the rubber layer corresponds to the slag outlet. The rubber layer increases the sealing between the baffle and the slag outlet, thereby preventing glycerin from leaking during the filtration process and affecting the practicality of the device.

[0022] Furthermore, the outer surface of the separation cylinder is provided with an observation window, which is made of transparent acrylic.

[0023] By adopting the above technical solution, the acrylic observation window has extremely high transparency, which can clearly display the internal items. It is also easy to process and has low cost. Workers can observe the inside of the separation cylinder through the observation window to keep track of the production process, so as to deal with any problems that arise inside, thereby improving production efficiency.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by setting up a scraper and a filter cylinder, removes impurities from crude glycerin. Under the drive of the output end of the servo motor, the rotating shaft drives the scraper to rotate, so that the glycerin rotates inside the filter cylinder. Centrifugal force accelerates the speed at which the glycerin passes through the filter holes on the filter cylinder, thereby improving the filtration efficiency. At the same time, the side wall of the scraper contacts the inner wall of the filter cylinder, scraping away the impurities adsorbed on the filter cylinder, avoiding the impurities adsorbed on the filter cylinder wall and causing the filter holes to be blocked, thus affecting the filtration effect.

[0026] 2. This utility model is equipped with a first magnet, a second magnet, a baffle, and a rubber layer. When the scraper rotates, the first magnet and the second magnet are magnetically attracted to each other. When the servo motor rotates forward, the first magnet drives the baffle to move to one side of the first chute under the limit of the first chute, and the second magnet drives the baffle to close the slag outlet. The rubber layer improves the sealing between the baffle and the slag outlet, preventing leakage from the slag outlet during glycerin filtration. When the servo motor rotates in reverse, the second magnet drives the baffle to move to the other side of the first chute, opening the slag outlet. Therefore, it is not necessary to stop the device to clean the impurities, so as to realize continuous production and improve production efficiency.

[0027] 3. This utility model is equipped with a collision rod, a guide plate and a spring. After the impurities fall into the guide plate, the shaft drives the collision rod to rotate under the drive of the servo motor output. During the rotation of the collision rod, it intermittently collides with the collision block. In cooperation with the spring, the guide plate slides up and down on one side to generate vibration. The vibration increases the movement speed of the impurities on the guide plate, thereby quickly discharging the impurities from the separation cylinder. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A continuous glycerol refining and impurity removal device, such as Figures 1-5 As shown, the system includes a base 1 and a separation cylinder 2. A servo motor 5 is mounted on the top of the separation cylinder 2, and a rotating shaft 6 is connected to the output end of the servo motor 5. A collision rod 14 is connected to the bottom end of the rotating shaft 6, and a scraper 7 is connected to the outer surface of the rotating shaft 6. A first magnet 8 is installed at the bottom of the scraper 7. A filter cylinder 4 is placed inside the separation cylinder 2 via a support ring. A slag outlet 10 is opened at the bottom of the filter cylinder 4, and a baffle 12 is connected inside the slag outlet 10. A second magnet 13 is installed on one side of the top of the baffle 12. Two mounting plates 15 are connected to one side of the bottom of the filter cylinder 4, and a guide plate 16 is connected between the two mounting plates 15 via a rotating rod 17. A collision block 18 and a spring 19 are connected to the bottom of the guide plate 16. One end of spring 19 is connected to mounting plate 15. A feed pipe 3 is installed on the upper side of one side of the separation cylinder 2, and a discharge pipe 9 is installed on the other side of the separation cylinder 2. Both the feed pipe 3 and the discharge pipe 9 are equipped with valves. When the operator opens the valves (not shown in the figure), the crude glycerin enters the filter cylinder 4 through the feed pipe 3 for filtration. Driven by the output of servo motor 5, the rotating shaft 6 drives the scraper 7 to rotate and agitate the glycerin, causing the glycerin to swirl and circulate inside the filter cylinder 4. By agitating the glycerin through the scraper 7, the filtration speed of the glycerin through the filter holes on the filter cylinder 4 is accelerated. The filtered glycerin is then transported to the next process through the discharge pipe 9 for further processing.

[0037] See Figure 2 and Figure 3In the above embodiment, the scraper 7 is in contact with the inner wall of the filter cylinder 4. After the crude glycerin enters the filter cylinder 4, it is rotated inside the filter cylinder 4 by the scraper 7. The centrifugal force accelerates the speed at which the glycerin passes through the filter holes on the filter cylinder 4, thereby improving the filtration efficiency. At the same time, the side wall of the scraper 7 is in contact with the inner wall of the filter cylinder 4, scraping away the impurities adsorbed on the filter cylinder 4, and preventing impurities from adsorbing on the inner wall of the filter cylinder 4 and causing the filter holes to become blocked.

[0038] See Figure 2 , Figure 3 and Figure 5 In the above embodiment, the bottom of the filter cylinder 4 is provided with a first sliding groove 11, and the baffle 12 is slidably connected to the filter cylinder 4 through the first sliding groove 11. When it is necessary to clean the impurities inside the filter cylinder 4, the operator closes the valve of the feed pipe 3 and starts the servo motor 5 to reverse. The output end of the servo motor 5 drives the rotating shaft 6 to rotate, thereby driving the scraper 7 to rotate in the opposite direction. Under the drive of the scraper 7, the first magnet 8 and the second magnet 13 are magnetically attracted. The first magnet 8 drives the second magnet 13 to move along the first sliding groove 11, thereby driving the baffle 12 to move and release the obstruction of the slag outlet 10. At the same time, the scraper 7 scrapes the impurities into the slag outlet 10 and leaves the filter cylinder 4. There is no need for manual cleaning of the impurities inside the filter cylinder 4, thereby speeding up the production efficiency.

[0039] See Figure 2 , Figure 3 and Figure 5 In the above embodiment, both the first magnet 8 and the second magnet 13 are neodymium magnets. Neodymium magnets have strong magnetic force, high mechanical strength, are not easy to break, and have a long service life. Through the magnetic attraction between the first magnet 8 and the second magnet 13, when the servo motor 5 rotates forward, the first magnet 8 drives the second magnet 13 to move the baffle 12 to one side of the first chute 11 under the limit of the first chute 11, thus closing the slag outlet 10. When the servo motor 5 rotates in reverse, the second magnet 13 drives the baffle 12 to move to the other side of the first chute 11, thus opening the slag outlet 10. Therefore, it is not necessary to stop the device to clean the impurities, thereby realizing continuous production and improving production efficiency.

[0040] See Figure 4 In the above embodiment, the collision block 18 has an inverted triangular cross-section, and the collision rod 14 is in contact with the collision block 18. Driven by the output of the servo motor 5, the rotating shaft 6 drives the collision rod 14 to rotate. During the rotation of the collision rod 14, it intermittently collides with the collision block 18. In conjunction with the spring 19, it causes the guide plate 16 to slide up and down on one side and generate vibration. The vibration increases the movement speed of impurities on the guide plate 16, thereby quickly discharging them from the separation cylinder 2. The triangular arrangement allows the collision rod 14 to quickly detach after contacting the collision block 18 when rotating forward or backward.

[0041] See Figure 4 In the above embodiment, there are two sets of rotating rods 17, and one set of rotating rods 17 is rotatably connected to the mounting plate 15. The rotating rods 17 drive the guide plate 16 to rotate within a small range between the two mounting plates 15 and cooperate with the spring 19. When the collision rod 14 contacts the collision block 18, the guide plate 16 vibrates. Through the vibration generated and guided by the guide plate 16, the impurities are quickly discharged from the separation cylinder 2.

[0042] See Figure 2 and Figure 4 In the above embodiment, a second sliding groove 20 is provided in the mounting plate 15, and another rotating rod 17 is slidably connected to the mounting plate 15 through the second sliding groove 20. The second sliding groove 20 cooperates with the other rotating rod 17 to limit the guide plate 16, thereby controlling the rotation amplitude of the guide plate 16 and keeping the rotation amplitude within a certain range.

[0043] See Figure 2 , Figure 3 and Figure 5 In the above embodiment, the bottom of the baffle 12 is provided with a rubber layer 22, which corresponds to the slag outlet 10. By providing the rubber layer 22, the sealing between the baffle 12 and the slag outlet 10 is increased, thereby preventing glycerin from leaking during the filtration process and affecting the practicality of the device.

[0044] Example 2: To facilitate staff understanding of the internal workings of the device, Example 2 is an improvement upon Example 1. (See attached document.) Figure 1 The outer surface of the separation cylinder 2 is provided with an observation window 21, which is made of transparent acrylic. The acrylic observation window 21 has extremely high transparency, which can clearly display the internal items. It is also easy to process and has low cost. The staff can observe the inside of the separation cylinder 2 through the observation window 21 to grasp the production process, so as to deal with the problems that arise inside, thereby improving production efficiency.

[0045] The implementation principle of this utility model is as follows: The operator starts the servo motor 5 to rotate forward. Under the drive of the output end of the servo motor 5, the rotating shaft 6 drives the scraper 7 to rotate. Under the drive of the scraper 7, the first magnet 8 and the second magnet 13 are attracted, thereby driving the baffle 12 to move and close the slag outlet 10. After the slag outlet 10 is closed, the operator opens the valves on the feed pipe 3 and the discharge pipe 9 respectively. The crude glycerin continuously enters the filter cylinder 4 through the feed pipe 3. The scraper 7 agitates the glycerin, causing the glycerin to swirl and circulate inside the filter cylinder 4. At the same time, the side wall of the scraper 7 contacts the inner wall of the filter cylinder 4, scraping away the impurities adsorbed on the filter cylinder 4. The filtered glycerin is transported to the next process through the discharge pipe 9 for subsequent processing.

[0046] When there are too many impurities in the filter cylinder 4 and cleaning is required, the operator closes the valves on the feed pipe 3 and the discharge pipe 9 respectively, controls the servo motor 5 to reverse, and the output end of the servo motor 5 drives the rotating shaft 6 to rotate, thereby driving the scraper 7 to rotate in the opposite direction. Under the drive of the scraper 7, the first magnet 8 and the second magnet 13 are magnetically attracted. The first magnet 8 drives the second magnet 13 to move along the first slide groove 11, thereby driving the baffle 12 to move and release the obstruction of the slag outlet 10. At the same time, the scraper 7 scrapes the impurities into the slag outlet 10, so that the impurities leave the filter cylinder 4 and fall into the guide plate 16. Meanwhile, under the drive of the rotating shaft 6, the collision rod 14 intermittently collides with the collision block 18 during rotation and cooperates with the spring 19 to make the guide plate 16 vibrate. The vibration makes the movement speed of the impurities on the guide plate 16 faster, thereby quickly discharging the impurities from the separation cylinder 2.
