Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, and particularly relates to a filtering structure of a kudzu powder concentrating cyclone. Background Technique

[0002] In the process of kudzu starch processing, cyclones are usually used to purify and concentrate the starch slurry to improve the extraction rate and quality of starch. Through the treatment of the concentrating cyclone, impurities in the starch slurry can be removed, and at the same time, the concentration of starch can be increased, which provides convenience for subsequent processes such as drying and packaging. However, there are still some deficiencies in the existing cyclones during use.

[0003] For example, a kudzu powder concentrating cyclone with a publication number of CN218871381U can replace the filter screen at any time according to needs through a lifting member and a connecting member, which is convenient for the staff to clean and maintain it. Since a cleaning brush is arranged inside the feed pipe, although the cleaning brush can clean the filter screen, the volume of the cleaning brush is relatively large, resulting in a decrease in the flow rate of the kudzu powder solution in the feed pipe, affecting the efficiency and output of the entire concentrating process, and it is not convenient to clean the slag discharge pipe.

[0004] Therefore, we propose a filtering structure of a kudzu powder concentrating cyclone to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a filtering structure of a kudzu powder concentrating cyclone to solve the problems in the above background technique, that is, the relatively large volume of the cleaning brush in the current market leads to a decrease in the flow rate of the kudzu powder solution in the feed pipe, affecting the efficiency and output of the entire concentrating process, and it is not convenient to clean the slag discharge pipe.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A filtering structure of a kudzu powder concentrating cyclone, including a cylinder body, a sand discharge port is opened at the bottom end of the cylinder body, an overflow port is opened at the top end of the cylinder body, and a feed pipe is fixedly connected to the side wall of the cylinder body;

[0007] It further includes:

[0008] A group of chutes are symmetrically arranged inside the feed pipe, a slag discharge port is opened at the bottom end of the feed pipe, and a shunt pipe for shunting is connected to the outside of the feed pipe. Two sliders are movably connected in the two chutes, a filter screen is fixedly connected to the side walls of the opposite sides of the two sliders, and a slag cleaning mechanism is rotatably installed inside the filter screen. A collection box is fixedly connected to the outer side wall of the feed pipe below the slag discharge port. A blocking plate is arranged inside the feed pipe, the upper end of the blocking plate penetrates through and extends out of the feed pipe, and a fixing rod is movably connected to the blocking plate.

[0009] Preferably, a first spring is connected between the slider and the chute, and an elastic telescopic structure is formed between the slider and the chute through the first spring.

[0010] Preferably, the slag cleaning mechanism includes a scraping blade, a rotating shaft and a water wheel. The rotating shaft is rotatably installed in the filter screen, and one end of the rotating shaft penetrates and extends out of the filter screen. The extending end of the rotating shaft is fixedly connected to the water wheel. The end of the rotating shaft away from the water wheel penetrates and extends out of the filter screen, and the extending end of the rotating shaft is fixedly connected to the scraping blade. The scraping blade is attached to the surface of the filter screen, and the filter screen corresponds to the slag discharge port.

[0011] Preferably, the slag cleaning mechanism further includes a baffle. The baffle is fixedly connected to the side wall of the filter screen, and two groups of baffles are symmetrically arranged. Openings are formed on both groups of baffles, and a liquid hole is formed on one of the baffles. Both groups of baffles are arranged in an arc structure.

[0012] Preferably, two blocking plates are symmetrically arranged with respect to the feed pipe. The two blocking plates are located between the shunt pipe and the filter screen.

A second spring is connected between the fixing rod and the blocking plate, and an elastic telescopic structure is formed between the fixing rod and the blocking plate through the second spring.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The filtering structure of the kudzu powder concentrator cyclone can utilize the impact of the kudzu powder solution to automatically clean the filter screen during use, and can clean the filtered residue without stopping the transportation. The specific content is as follows:

[0015] 1. The slider and the filter screen are provided. When the filter screen is blocked, the kudzu powder solution will impact the filter screen at this time, causing the filter screen to drive the slider to slide along the chute, thereby squeezing the first spring to contract, causing the filter screen to drive the baffle to move backward. While automatically opening the shunt pipe, the blocking plate will move downward under the action of the elastic force of the second spring, and then pass through the opening to block the front and rear ends of the filter screen. At this time, the filter screen is aligned with the slag discharge port, and the water wheel will rotate under the impact of the kudzu powder solution, thereby driving the scraping blade to rotate and cleaning the filter screen.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1 - 5 As shown in the figure, the present utility model provides a technical solution: a filtering structure of a kudzu root powder concentrator cyclone, including a cylinder body 1, a sand discharge port 2 is opened at the bottom end of the cylinder body 1, an overflow port 3 is opened at the top end of the cylinder body 1, and a feed pipe 4 is fixedly connected to the side wall of the cylinder body 1.

[0024] With the setting of the feed pipe 4 in this technical solution, when in use, a container filled with kudzu root powder solution is connected to the feed pipe 4 through a pipeline, and then the pump is started to convey the kudzu root powder solution into the feed pipe 4 and then into the cylinder body 1 through the feed pipe 4. When the kudzu root powder slurry enters the concentrator cyclone, the rotating device will cause it to generate a swirling flow. The centrifugal force generated by this swirling flow will force the larger kudzu root powder particles to gradually settle outward, while the smaller particles or liquid will continue to rotate with the fluid. The kudzu root powder particles that settle to the bottom are discharged from the cyclone through the sand discharge port 2, and the relatively clean liquid part is discharged from the cyclone through the overflow port 3.

[0025] Example 2: The technical content disclosed in this example is an improvement based on Example 1 above. Currently, due to the large volume of the cleaning brush, the flow rate of the kudzu powder solution in the material pipe is reduced, affecting the efficiency and output of the entire concentration process. The technical solution is as follows Figure 1 and Figure 5 shown. It discloses the filtering component of the hydrocyclone. A group of chutes 5 are symmetrically arranged in the feed pipe 4. A slag discharge port 6 is opened at the bottom end of the feed pipe 4. A diversion pipe 7 for diversion is connected to the outside of the feed pipe 4. Two sliders 8 are movably connected in the two chutes 5. A filter screen 9 is fixedly connected to the side walls of the opposite sides of the two sliders 8. A first spring 14 is connected between the slider 8 and the chute 5. The slider 8 and the chute 5 form an elastic telescopic structure through the first spring 14.

[0026] In this technical solution, as shown in Figure 1 shown, by setting the filter screen 9, large particle impurities, incompletely pulverized kudzu blocks and possible foreign matters in the kudzu powder solution can be effectively removed, ensuring the purity of the raw materials in the subsequent processing process.

[0027] It adopts the technical solution as shown in Figure 5 shown. First, the filter screen 9 will conduct preliminary filtration on the kudzu powder solution. When the kudzu powder solution passes through the filter screen 9, the solid particles in the solution will be screened according to their particle size. Particles with a particle size larger than the pore size of the filter screen 9 will be intercepted by the filter screen 9 and remain on the surface of the filter screen 9, while particles with a particle size smaller than or equal to the pore size of the filter screen 9 can smoothly pass through the filter screen 9 and enter the cylinder 1.

[0028] Example 3: The technical content disclosed in this example is a further improvement based on Example 1 and Example 2 above. Since it is not convenient to clean the slag discharge pipe, in order to further solve this technical problem, the technical solution is as follows Figures 2 - 3As shown, a cleaning component of a cyclone is disclosed. A slag cleaning mechanism is rotatably installed inside a filter screen 9. A collecting box 10 is fixedly connected to the outer side wall of a feed pipe 4 below a slag discharge port 6. A blocking plate 12 is arranged inside the feed pipe 4, and the upper end of the blocking plate 12 penetrates and extends out of the feed pipe 4. A fixing rod 13 is movably connected to the blocking plate 12. The slag cleaning mechanism includes a scraping blade 15, a rotating shaft 16 and a water wheel 17. The rotating shaft 16 is rotatably installed inside the filter screen 9, and one end of the rotating shaft 16 penetrates and extends out of the filter screen 9. The extending end of the rotating shaft 16 is fixedly connected to the water wheel 17. The end of the rotating shaft 16 away from the water wheel 17 penetrates and extends out of the filter screen 9, and the extending end of the rotating shaft 16 is fixedly connected to the scraping blade 15. The scraping blade 15 is attached to the surface of the filter screen 9. The filter screen 9 corresponds to the slag discharge port 6. The slag cleaning mechanism further includes a baffle plate 18. The baffle plate 18 is fixedly connected to the side wall of the filter screen 9. Two groups of baffle plates 18 are symmetrically arranged. Openings 19 are formed in both groups of baffle plates 18. A liquid hole 20 is formed in one of the baffle plates 18. Both groups of baffle plates 18 are arranged in an arc structure. Two blocking plates 12 are symmetrically arranged with respect to the feed pipe 4. The two blocking plates 12 are located between a shunt pipe 7 and the filter screen 9. The two blocking plates 12 are both slidably connected to the feed pipe 4. The blocking plates 12 correspond to the openings 19 one by one. The water outlet at the end of the shunt pipe 7 corresponds to the liquid hole 20. The liquid hole 20 corresponds to the water wheel 17. Two fixing rods 13 are symmetrically arranged with respect to the blocking plate 12. The bottom ends of the two fixing rods 13 are fixedly connected to the outer wall of the feed pipe 4. A second spring 11 is connected between the fixing rod 13 and the blocking plate 12. The fixing rod 13 and the blocking plate 12 form an elastic telescopic structure through the second spring 11.

[0029] In this technical solution, as Figure 2 shown, by using the arrangement of the scraping blade 15, the rotating shaft 16 and the water wheel 17, when the filter screen 9 is blocked, at this time the blocking plate 12 will block the feed pipe 4, so that the kudzu powder solution flows through the shunt pipe 7, thereby impacting the water wheel 17, causing the water wheel 17 to drive the scraping blade 15 to rotate through the rotating shaft 16. The rotating scraping blade 15 will scrape off the impurities on the surface of the filter screen 9, making them fall into the collecting box 10 for collection. Thus, automatic cleaning is realized without affecting the normal operation of the device, and the production efficiency is improved.

[0030] It adopts such as Figure 1 and Figures 3 - 5In the technical solution shown, first, when the filter screen 9 becomes blocked, the filter screen 9 will be pushed backward by the kudzu powder solution, thereby driving the slider 8, the rotating shaft 16, and the water wheel 17 to move synchronously. While the slider 8 slides backward along the chute 5, it squeezes the first spring 14 to contract. At the same time, the filter screen 9 drives the baffle 18 to move. Immediately afterwards, the baffle 18 in front of the filter screen 9 gradually moves away from the shunt pipe 7, opening the liquid inlet of the shunt pipe 7. The liquid holes 20 on the baffle 18 behind the filter screen 9 are aligned with the liquid outlet of the shunt pipe 7. At this time, the plugging plate 12 is aligned with the opening 19 on the baffle 18. Thus, under the elastic force of the second spring 11, the plugging plate 12 is pushed into the feed pipe 4 to achieve plugging, thereby forming a blank area before and after the filter screen 9. At this time, the kudzu powder solution will flow out through the shunt pipe 7, and then impact the water wheel 17, causing the water wheel 17 to drive the rotating shaft 16 to rotate, and then driving the scraping blade 15 to rotate. The scraping blade 15 will clean the surface of the filter screen 9, and the scraped impurities will fall into the collection box 10 for collection.
